Abstract

The utility model relates to a quick stopping leak joint which provides the fast steady jointing of a tube used for the diversion of liquid indoors and outdoors and has the effect of safety and leakage stopping. The outer tube of a joint body is provided with a conical inner tube whose caliber on an outer end is slightly small and caliber on an inner end is slightly large, and a thimble groove for the embedding of the tube is formed between the outer tube and the inner tube; the inner side on the upper part of the outer tube is additionally provided with a pushing pulling surface which are for the embedding of a rubber leakage stopping ring and a lantern ring. The purpose of novelty, practicality, use value promoting can be obtained through the action of a vacuum suction thimble presenting a bevel-shaped on the inner side of the rubber leakage stopping ring and the tube and utilizing the tabling of an embedding block which is arranged outside the lantern ring and the embedding hole of the outer tube.

Description

Quick stopping leak joint

The utility model relates to a kind of quick stopping leak joint, and it comprises joint body, rubber drop-stopping ring and the collar, and it can make, and joint body engages with pipe way rapidly, firm, stopping leak safety again.

General common joint structure, see also shown in Figure 1ly, it is respectively equipped with joint 10 mainly in the end of joint body 1, after pipe 2 inserts sleeve pipe 11 inside of

joint

10,11 of pipe 2 outer walls and sleeve pipes form trickle gap, then provide polyethylene (PVC) pipe to connect agent 12 and insert, and with the hands help through a period of time, beginning can be solidified joint, time-consumingly take a lot of work again, and since the not good relation of this kind staple structural design use a period of time to be easy to cause and get loose.

For overcoming above-mentioned disappearance, main purpose of the present utility model is to provide a kind of quick stopping leak joint, and it can make, and joint body engages with pipe way fast, firm, stopping leak safety again.

Another purpose of the present utility model is to provide a kind of quick stopping leak joint, and it is simple in structure, manipulates maintenance and goes up simply easily, more saves cost than staple.

For achieving the above object, the quick stopping leak joint that provides of the utility model comprises joint body, rubber drop-stopping ring and the collar; It mainly becomes to have inner and outer pipes with the head design of joint body, and make formation therebetween for the capel groove of pipe sleeve, and the outer tube inner top side is provided with pushing face-drawing, with be provided with in providing respectively vacuum inhale capel be embedded the rubber drop-stopping ring of absorption with pipe and be provided with outward with outer tube on the collar of the chimeric abaculus in embedding hole, make it to form a firm integral body.

For other features of the present utility model, purpose and advantage can more be manifested, now lift preferred embodiment conjunction with figs. explanation as back:

Fig. 1 connects sectional drawing that agent engage with pipe by PVC jelly or PVC for staple;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is a combination front elevation of the present utility model;

Fig. 3 A cuts open figure for C-C among Fig. 3;

See also shown in Figure 2, be three-dimensional exploded view of the present utility model, it mainly includes joint body 3, drop-stopping ring 35, the collar 36, wherein the head 30 of joint body 3 is made of outer tube 31 and interior pipe 32, and be provided with a capel groove 33 that is embedded for pipe 2 betwixt, simultaneously because outer tube 31 interior pipes 32 are length, and be provided with cancave embedded part 311 at the inside front of outer tube 31, be fixed in its inside to provide the rubber drop-stopping ring 35 and the collar 36 to be embedded, and around cancave embedded part 311 tops of outer tube 31, other is provided with the embedding hole of running through 34, and its purpose then provides the abaculus 361 in the collar 36 outsides to be embedded, to prevent that rubber drop-stopping ring 35 is broken away from by outer tube 31 places, as for the rubber drop-stopping ring 35 that is fixedly arranged on the pipe, its inboard then is provided with the vacuum with gradient and inhales capel 351, so that vacuum tight absorption to be provided, and pipe is inserted easily, and it is difficult to choose.

See also shown in Fig. 3, the 3A, be combination front elevation of the present utility model, sectional drawing, quite easy during its combination, only rubber drop-stopping ring 35 must be inserted earlier in the cancave embedded part 311 of outer tube 31 inside fronts of joint body 3, the collar 36 with hard embeds again, this moment, the abaculus that is inverted triangle 361 in the collar 36 outsides promptly can relatively easily be slipped in the embedding hole of running through outer tube 31 tops 34 by its inclined-plane, and then its three is fixed into one, in order to the pipe sleeve.

See also shown in Figure 5, A enlarged view partly for Fig. 3, the vacuum of its performance rubber drop-stopping ring 35 inside is inhaled capel 351 and is not subjected to pipe compressing vacuum suction situation, since the capel 351 of rubber drop-stopping ring 35 be 30 ° gradient (less than any angles of 90 degree all can), therefore, after pipe inserts, it can be inhaled the gradient effect of capel 351 by vacuum, and enter easily, compressing forms vacuum suction, when pipe 2 was desired to take out outward, this vacuum was inhaled capel 351 and promptly is difficult for being removed (please hold aftermentioned) just like barb and vacuum forces.

See also shown in Fig. 4, the 4A, be the utility model and pipe 2 chimeric front elevation and sectional drawing, because situation shown in the earlier figures 3,5, pipe 2 is not chimeric with the utility model, it is standby condition, after pipe 2 inserts, pipe 2 i.e. the collar 36 of elder generation's process head 30, to be the outstanding vacuum suction capel 351 of being located at rubber drop-stopping ring 35 inboards of gradient again presses down, and then form vacuum suction around pipe 2, till pipe 2 continues to advance, and manages in the 32 capel grooves 33 that constitute, promptly be the secure shape downwards in pipe 2 ends embed by outer tube 31 and taper.

See also shown in Figure 6, B part enlarged view for Fig. 4, because the insertion of pipe 2, causing the vacuum of being located in the rubber drop-stopping ring 35 to inhale capel 351 tightly is adsorbed in around the pipe 2, the capel 351 of vacuum suction simultaneously is the gradient shape, therefore pipe 2 inserts quite easy and convenient unaffected (promptly easily inserting), but when pipe 2 is outwards extracted because of its gradient barb and vacuum suction relation, therefore be difficult to extract, so can reach splendid stopping leak effect, pipe 2 also is subjected to the effect of the capel groove 33 and the collar 36 simultaneously, quite firm, safety, if desire to extract pipe 2 by joint body 3, then must the rubber drop-stopping ring 35 and the vacuum on pipe 2 surfaces be eliminated with rotation mode, begin to extract.And the rubber drop-stopping ring 35 of model utility and the collar 36 also can be chimeric with the head 30 of another form, shown in Fig. 4 A, this head 30 only is provided with outer tube 31, pipe 32 in not having, in outer tube 31, be provided with simultaneously for its two pushing face-drawing that is embedded 311, and also be provided with the embedding hole 34 that is embedded for the collar 36 outside abaculus 361 on the outer tube 31.

In sum, the utility model is forgone the disappearance of staple, the novel progressive practical effect of special tool, and promote this product use value.
