The way of fixing the elastic parts and shells of the metal band clamps
(57) Abstract:The invention relates to the field of fastening elastic parts and shells of the metal band clamps and can be used for fixing the rubber protective covers hinges of equal angular speeds of the front-wheel drive passenger cars. The way of fixing the elastic parts and shells of the metal band clamps includes wrapping tape clamp around the fixed part and the fastening end of the tape in the castle. According to the invention the tape clamp is wrapped twice and pass the end through the buckle lock, which is pre-fix polevkami on sinocom land with the bend angle 180othe other end of the tape. After tightening the clamp the tape re-bend 180oand separat by pressing antennae buckle lock. This results in a simpler design, in addition, this method does not bring imbalance to fasten the parts subjected to rotation, provides a tight seal. 2 Il. The invention relates to the field of fastening elastic parts and shells of the metal band clamps and can be used for fixing the rubber protective covers joints of equal Uglova and shells, including wrapping tape metal clamp around the fixed part with threading the ribbon end through the screw securing the end of a lock in the form of worm pairs (see leaflet 2.1 company "NORMA", Germany).A known method of fixation has some significant drawbacks:
the imbalance due to the significant mass of the castle, leading to vibration when using this method for mounting the rotating parts and shells;
complex technology installation, requiring the use of special tools.Closest to the claimed method is a method of fixing the elastic parts and shells of the metal belt clips, including the wrapping of the tape clamp around the fixed part and the fastening end of the tape through action crimp tool for special grips, made in the castle (see leaflet 3.5. company "NORMA", Germany).A significant disadvantage of this method of fixation is a complex technology manufacturing and installation clamps, due to the shape of the tape and lock clamp, and the use of special installation tools.The objective of the invention is to provide a method which makes a difference on the fixed parts, undergoing rotation with providing reliable air-tightness of the connection.The task is achieved in that in the method of fixing the elastic parts and shells of the metal belt clips, including the wrapping of the tape clamp around the fixed part of securing the ends of the belt in the castle, according to the invention the tape clamp is wrapped twice and pass the end through the buckle lock, which is pre-fix polevkami on sinocom plot with a bend angle 180othe other end of the tape, after tightening of the fastener tape re-bend 180oand separat by pressing antennae buckle lock.The proposed method of fixing the elastic parts and shells of the metal band clamps is different from the prototype in essential characteristics:
the belt clip is wrapped twice around the fixed part;
- threading the belt end through the buckle lock;
- buckle lock pre-fix polevkami on sinocom plot with a bend angle 180othe other end of the tape;
- after tightening the clamp the tape re-bend 180o;
- tape separat by pressing antennae buckle lock.Therefore, the proposals by slipping the ends of the belt through the buckle lock and pre-fastening of the buckle polevkami allows tightly clasp elastic membrane, providing uniform contact pressure along the perimeter of the compound, and the presence of puklavec provides reliable fastening of the buckle lock when exposed to considerable effort tighten the clamp with subsequent locking by clamping bars of the buckle lock.In the proposed invention, all the hallmarks are interrelated and in combination with other features allow you to obtain a new technical result, to simplify the technology of manufacturing and installation, to ensure the reliability of connection
Therefore, the proposed invention meets the criterion of "inventive level".The invention is illustrated by drawings, where figure 1 shows a General view of the metal belt clip to implement the method of Fig.2.Metal belt clip contains the tape 1, one end of which is the castle, made by bending a flat plate 2 and forms a buckle with 3 antennae 4, which is fixed on the tape using puklavec 5
Fixation is performed by wrapping tape 1 twice around the elastic membrane 6, jamming the end of the tape 1 through the buckle 3, which is pre-fixed on poklevki 5 sinocom plot with a bend angle 180ofrom the other end of the LASS="ptx2">Application of the proposed invention will provide a secure elastic parts and shells, to ensure a tight seal, will greatly simplify the technology of manufacturing and assembling the parts used in this method of fixation. The way of fixing the elastic parts and shells of the metal belt clips, including the wrapping of the tape clamp around the fixed part and the fastening of the belt end in the lock, characterized in that the belt clip is wrapped twice and pass the end through the buckle lock, which is pre-fix polevkami on sinocom land with the bend angle 180othe other end of the tape, after tightening of the fastener tape re-bend 180oand separat by pressing antennae buckle lock.
SUBSTANCE: said invention relates to quick-release elements of flange connections, in particular, to band clamps. The clamp consists of a tie band with loop knots, in which band-fixed tie elements are installed, and a tie bolt and nut. On one side of the tie band there is a recess, links being provided with outer clamps, while tension sleeves with side shoulders act as tie elements. On shoulders of the first sleeve, there are flats, while inner surfaces of the other sleeve are parallel-plane, a clearance of 2-3% of the tie band outer diameter is being provided between the sleeve flat surface and the nut end.
EFFECT: enhanced reliability of the machine fastening security and enhanced ease of the clamp manufacture and installation.
SUBSTANCE: invention relates to devices for split joints of axisymmetric cylindrical or conical details. The device consists of a tension tape covering details to be jointed together in planes of tension, a tension belt and tightening elements. Tie bars are arranged on the tension tape inside to interact with the details flanges. The tension belt passes around of bolts of the tension tape, the bolts being located perpendicular to a direction of the tension tape stretching. Two opposite removable bolts are interconnected by means of the tightening element. Every tightening element consists of two tightening levers fixed to turn on the support plate at a distance from each other. The support plate accommodates the bolts to locked in tightened position. On releasing, the tightening levers are loaded by slowing down elements.
EFFECT: adjustable and optimised release of axisymmetric details.

SUBSTANCE: sprinkler clip comprises bending loop-like support clamp with its ends furnished with one hole and superimposed in closed position. Note here that, in the said position, the first hole in the inside end of support clamp mates the second hole on the clamp outside end so that the clamping element is received into both holes, the said clamping element being furnished with a radial ledge resting upon inside hole edge from inside. In compliance with the invention, the second hole cross section differs from that of the first hole, and that the clamping element is furnished with a radial bulge at a distance from the previously mentioned radial ledge, which allows the clamping element to be held on the fist hole edge without slippage and to enter the second hole.
EFFECT: simple and reliable fastening of sprinkler pipelines on mounting components.

SUBSTANCE: strip of clamp is wrapped around wrapped part: at first fixing end of strip is secured in locking device, then this end is bent to 180 degrees and finally fixed by filaments of locking device. Locking device is made by doing three cuts on end locking part of strip parallel to the main direction of the strip (at that length of cut is more than width of strip), by further bending of four straps perpendicular to the main direction of the strip into directions corresponding to directions of straps location relative to the strip, by use of two formed filaments for initial attachment of fixing end of strip in locking device and two other filaments for final attachment of fixing end of strip. For initial attachment of strip in locking device filaments formed by outer straps may be used. For attachment of end of bent strip filaments formed by inner straps may be used. Length of central cut is 1/4 of strip width more than lengths of side cuts.
EFFECT: improving production effectiveness and autonomy production, reducing dimensions of mounted clamp with locking device.
