(57) Abstract:Usage: securing the hose to the nipple. The inventive clamp contains two split cylindrical ring of the same diameter and of different width. One ring installed in the groove of the other rings coaxially with the latter. O-rings are made with curved ends. One end of each ring is made with emphasis. The emphasis turned to the other bent end of the same ring. The ends of the rings are connected by fasteners. Each axis of the fastening element is located relative to the cylindrical part of the ring and stops, respectively, at a distance equal to 1/2 and 3/4 of the diameter of the head of the fastening element. The clamp allows you to squeeze the hose to the nipple evenly around the entire circumference of the nipple with considerable effort. 1 C.p. f-crystals, 6 ill. The invention relates to mechanical engineering and can be used for connection to the hose nipple.Known for the design of the clamp steel wire, both ends of which is made of the sawtooth teeth, putting the ends in engagement with each other 
The disadvantages of the known constructions of the clip are small, the strength of the connection of the hose nipple (pipe) and the engagement of the ends of the clamp each one is s, the technological difficulty of obtaining a sawtooth teeth.The famous design of the clip, which represents a split cylindrical ring, unbent ends with holes for placement of the screw, tightening the clamp with nuts 
The disadvantages of the known constructions of the clip are the lack of integrity and sufficient strength of the connection of the hose nipple. When installing such a clamp plate it occurs unilaterally, respectively, and the hose begins to cling to the nipple under the action of the clamp with one hand. The result will inevitably be formed collection hose (bloating above the surface of the nipple against the open part of the clip. This leads to a significant leak in the connection. Such leaks occur, for example, the operation of the submersible domestic pumps supplying water from a depth of well or wells, the installation of which are also used clamps.Leakage through the loose connection of the hose nipple (fitting pump) in the above pumps are amplified even more by the fact that at the connection of the hose with the pump, there is a considerable pressure (2oC 6 ATI), defined by the depth of the borehole or well. In the leakage syamsoeddin hose with nipple (fitting pump) while maintaining sufficiently high processability of the clip.This is ensured by the fact that the clamp containing a split cylindrical ring with curved ends and fasteners on them, equipped with an additional split cylindrical ring with a diameter equal to the diameter of the main ring, with a groove width of the main ring, with curved ends and fasteners on each main ring installed in the groove of additional rings coaxially with him. In addition, one of the bent ends of each ring can be made with emphasis directed toward the other bent end of the same ring, and each axis of the fastening element is located relative to the cylindrical part of the ring and stops, respectively, at a distance equal to 1/2 and 3/4 of the diameter of the head of the fastening element.In Fig. 1 shows a clamp mounted on the hose nipple; Fig. 2 longitudinal section of the clamp, the hose and the nipple of Fig. 1; Fig. 3 is a view in plan of one of the rings of the two members of the clamp; Fig. 4 is a side view of the ring of Fig. 3; Fig. 5 is a view in plan of the second ring clamp; Fig. 6 is a side view of the second ring clamp of Fig. 5.The clamp consists of two cylindrical rings 1 and 2 of the same diameter D with bent ends 3 and 4, with stops in their approach (stops the entire cylindrical part 9 of the ring 2. With this design, the ring 1 may include laterally in the other ring 2 to a complete matching of the diameters of the rings.Holes 10 and 11 are from the cylindrical surfaces 7 and 9 of each of the rings 1 and 2 at a distance 1/2 d, and from the stops 5 and 6 at a distance of 3/4 d (Fig. 1).The clamp can also be used to connect the hose over the nipple. For this purpose, the free right end of the nipple 12 (Fig. 2) install a second hose (Fig. 2 is not shown) and is mounted similarly to the fastening of the hose 13 to the left end of the nipple 12.When the operation of pumping systems with clamps, no leakage of the fluid in the hose connections with fittings (nipples) pumps or hose with hose and breakdowns hose nipples.A technical advantage of the clip is that it allows you to squeeze the hose to the nipple evenly around the entire circumference of the nipple with considerable effort, defined by tightening the two screws. Uniform pressure to the cylindrical surface of the nipple due to the fact that the hose is covered by a ring clamp simultaneously over its entire circumference from the beginning to the end of its tightening. Increasing efforts are being pressed to the nipple promotes certain of sobrannosti.All the details of the clip can be manufactured by stamping on high-efficiency equipment. 1.
