Abstract

The utility model relates to a toothless pipe joint, which is composed of a clamp sleeve barrel, an upper loop biting ring, a stanch rubber ring, a lower loop biting ring, a C-shaped cramp ring and a main joint pipe head. The C-shaped cramp ring is sealed in a concave ring slot on the outer margin of the main joint pipe head, a convex part is used for buckling the inner part of a penetration slot arranged in the ring slot, the main joint pipe head is respectively in turn inserted into the upper loop biting ring, the stanch rubber ring and the lower loop biting ring. The clamp sleeve barrel is sheathed, pressed and combined on the upper loop biting ring, the C-shaped cramp ring is inserted and buckled in caulking slots on the periphery of the clamp sleeve barrel, and the clamp sleeve barrel is pressed inside by buckling. The upper and the lower loop biting rings in the clamp sleeve barrel are engaged on the pipe wall of a joint pipe in a bidirectional way. The utility model reaches the effects of leakage resistance, high pressure resistance, strong solid-connection force and fast engaging speed. The utility model is a pipe joint reaching a triple clamping effect by one clamp sleeve barrel.

Description

No dentition formula pipe joint

The utility model belongs to pipe-line equipment, relates in particular to a kind of no dentition formula pipe joint.

The pipe joint that tradition is used, by spiral shell seat and nut locking, establish one at spiral shell seat upper end inner edge and compress cushion rubber, during locking nut, make the top that compresses cushion rubber inner top surface against lock nut, to take over the endoporus that inserts the spiral shell seat during joint, when lock nut is screwed down, compresses cushion rubber and take over, by the sealed strength of lock nut to the internal condensation compressing, impel to compress cushion rubber and urge pipe shaft, reach the effect that pipe joint engages.This pipe joint, easier during joint, quick, but its internal pressure that can bear is only in certain scope, because of it only compresses cushion rubber pressing pipe shaft with one, only play and pin adeciduate effect, can't bear bigger pulling force and anti-higher pressure, in case cushion rubber is aging, lose and compress effect, leak just inevitable.

The purpose of this utility model is to provide a kind of no dentition formula pipe joint, and it saves the main thread of taking over, and can reduce cost; It utilizes being forced into of clamp sleeve, makes the upper and lower ring application of force respectively of stinging, and forms the two-way wall that is engaged in main adapter and connecting tube, reaches two and takes over the state of stinging solid same position; It is upper and lower stings between ring folder and establishes the leak-stopping cushion rubber, and leakage-proof effect is good, slows down the aging of cushion rubber, thereby overcomes the defective that traditional product exists.

The utility model adopts following technological scheme:

No dentition formula pipe joint of the present utility model, it is by clamp sleeve, on sting ring, the leak-stopping cushion rubber, under sting ring, C shape clasp and main nipple are formed, clamp sleeve is a hollow sleeve, insert in main nipple, periphery wall is provided with multiple tracks ring-type caulking groove, be pressed on the lower end surface and sting ring, the leak-stopping cushion rubber is stung ring under reaching, on sting ring and be slightly convex of imploded arcs, the internal diameter periphery offers several line of rabbet joint that width is arranged slightly, dispose and be crushed on clamp sleeve root edge face, under sting toroidal ring structure with on to sting toroidal ring structure identical, both present in configuration, reverse cooperation down, leak-stopping cushion rubber cramping is last, under sting between ring, taking on the wall with interior radially the defeating that forms, C shape clasp opening two ends are provided with the handle groove, with outside latch closure mode latch closure in the annular groove of main nipple outer rim end, and with five equilibrium indent formula protuberance that it was provided with, scarf is tipped the main nipple annular groove in and is passed through in the groove, main nipple is inserted in regular turn and is stung ring, the leak-stopping cushion rubber is stung ring under reaching, its ora terminalis is provided with an annular groove, waits the groove that passes through that is arranged with for C shape clasp scarf in the annular groove.

Specifically narrate embodiment below in conjunction with accompanying drawing:

Ring (plan structure) schematic representation

Fig. 5 is the whole assembling of a utility model cross-sectional schematic

Fig. 6 is the best instrument schematic appearance that the utility model uses

Fig. 7 is Fig. 5 A-A part enlarged diagram

Among the figure, sting ring, 20 lines of rabbet joint, 3 leak-stopping cushion rubbers on 1 clamp sleeve, 11 caulking grooves, 2, sting ring for 4 times, 5C shape clasp, 51 protuberances, 52 handle grooves, 6 main nipples, 61 annular grooves, 62 pass through groove, 7 instruments, 8 are taken over walls

During enforcement, consult Fig. 1, shown in Figure 2, no dentition formula pipe joint of the present utility model, it is by clamp sleeve 1, on sting ring 2, leak-stopping cushion rubber 3, under sting ring 4, C shape clasp 5 and main nipple 6 are formed, clamp sleeve 1 is a hollow sleeve, insert in main nipple, periphery wall is established multiple tracks ring-type caulking groove 11, be pressed on the lower end surface and sting ring 2, under reaching, leak-stopping cushion rubber 3 stings ring 4, this triplicity has the double action of interlock and leak-stopping, on, under sting ring 2 and 4 whens assembling, for last, oppositely cooperate down, therebetween is established leak-stopping cushion rubber 3, on, under sting ring and be slightly convex of imploded arcs, the internal diameter periphery offers several line of rabbet joint that width is arranged slightly 20 (shown in Figure 3), on, under sting ring 2, behind 4 pressurizeds, the line of rabbet joint 20 that width is arranged is slightly shunk, make it be slightly convex trend pressing of imploded arcs, so that sting ring 2,4 interior ring is internal condensation radially, in the formation, each hoop embedding together is engaged in the great power of tube wall down, and therebetween by the leak-stopping cushion rubber 3 of clamping, except having the cushion rubber of preventing distortion, outside the advantages such as distortion, on being subjected to, under sting ring 2,4 clamping strength, and wall 8 is being taken in radially strength packing in producing, in the formation, following interlock and clamping, leak-stopping triple functions integrated (shown in Figure 7), as shown in Figure 4, C shape clasp 5 opening two ends are provided with handle groove 52, with outside latch closure mode latch closure in main nipple 6 outer rim end annular grooves 61, wait to be arranged with in the annular groove 61 and pass through groove 62, the five equilibrium indent formula protuberance 51 that is provided with C shape clasp 5, scarf is tipped passing through in the groove 62 of main nipple annular groove 61 in, reach the purpose of buckle at clamp sleeve 1 periphery caulking groove 11, as shown in Figure 5, during assembling will on sting ring 2, stinging 4 three elements of ring under leak-stopping cushion rubber 3 reaches packs into earlier, again with C shape clasp 5 buckles in the annular groove 61 of main nipple 6 outer rims, clamp sleeve 1 is pressed into along taking over 8 with opening mallet instrument 7 (shown in Figure 6), make C shape clasp 5 protuberances 51 one by one along the caulking groove 11 that imbeds clamp sleeve, make clamp sleeve 1 compress within it sting ring 2,4 and leak-stopping cushion rubber 3 (shown in Figure 4), if need fitting is recombinated, maintenance, during dismounting, only need C shape clasp 5 two ends handle grooves 52 are strutted, make it break away from the annular groove 61 of main nipple, just the clamp sleeve in it 1 can be deviate from, and remove simultaneously and sting ring 2 and 4 and the power that compresses of leak-stopping cushion rubber, reach fast and simple dress, tear effect open.

In sum, no dentition formula pipe joint of the present utility model, reasonable in design, novel, practical, simple, convenient, overcome the defective of traditional product, reach design purpose.
