Description
Technical field
The utility model relates to joint field, particularly relates to a kind of prolongable joint.
Background technique
Joint is used for connecting fast between flexible pipe, is communicated with the pipeline such as gas, liquid, is widely used in the every field in productive life.Common joint has straight-through, threeway and four-way, and the air pipe connector quantity of these joints is all fixing, can not expand.Joint market with expanding function does not generally have self-sealing function or can not infinitely expand.
Model utility content
The utility model, in order to solve the problem, proposes a kind ofly have self-sealing function and the joint that can infinitely expand.
To achieve these goals, the utility model is by the following technical solutions: a kind of prolongable joint, comprise major joint and offtake, described major joint comprises one and expands female and at least one air pipe connector, expand female to be communicated with air pipe connector inside, be provided with internal thread outside described expansion female, be provided with sealing cover inside internal thread, sealing cover is by spring compresses shutoff screw mouth; Described offtake comprises one and expands male, an expansion female and at least one air pipe connector, expand male, expansion female is communicated with air pipe connector inside, be provided with outside described expansion male and the outside thread expanded female internal thread and mate, end face is provided with boss, and boss is provided with breach; The expansion female of described offtake is the same with the expansion female structure of major joint.
As preferably, inside described spring, be provided with the retaining post of sealing cover.
As preferably, described air pipe connector is divided into nut joint and input termination, and described nut joint jointing main body and input termination, nut joint is provided with the screw thread mated with hold-doun nut, and described input end head portion is taper.
As preferably, sealing cover material is rubber or silica gel.
Therefore, the utility model has following beneficial effect: (1) has self-sealing function, and major joint can independently use; (2) can infinitely expand, easy to use; (3) adopt thread mechanism docking, connect reliable.

Embodiment
Below in conjunction with accompanying drawing and specific embodiments, the utility model is further described.
A kind of prolongable joint, see Fig. 1, Fig. 2, comprise major joint 1 and offtake 2, described major joint 1 comprises one and expands female 3 and two air pipe connectors 4, arrange in convex, two air pipe connectors 4 are oppositely arranged, expand female 3 and be located at centre, expand female 3 to be communicated with air pipe connector 4 inside, internal thread 8 is provided with outside described expansion female 3, the sealing cover 9 that silica gel is made is provided with inside internal thread 8, sealing cover 9 extrudes shutoff screw mouth by spring 10, realize selfsealings, the retaining post 14 of sealing cover 9 is provided with inside described spring 10, sealing cover 9 is made to press down certain distance, retaining post 14 is one-body molded with expansion female 3, also for restraining spring 10 position.
Described offtake 2 comprises one and expands male 5, expansion female 3 and two air pipe connectors 4, in cross setting, two air pipe connectors 4 are oppositely arranged, expand male 5 and expand female 3 and be oppositely arranged, expand male 5, expansion female 3 is communicated with air pipe connector 4 inside, be provided with outside described expansion male 5 and the outside thread 11 expanded female 3 internal thread 8 and mate, end face is provided with boss 12, for strutting the sealing cover 9 expanded in female 3, boss 12 is provided with breach 13, as shown in Figure 3; The expansion female 3 of described offtake 2 is the same with expansion female 3 structure of major joint 1.
Described air pipe connector 4 is divided into nut joint 7 and input termination 6, and described nut joint 7 jointing main body and input termination 6, nut joint 7 is provided with the screw thread mated with hold-doun nut, and described input termination 6 head is taper.
When only needing to use major joint 1, tracheae overlapping upper cap nut, then is connected on the input termination 6 of major joint 1 both sides air pipe connector 4 respectively, tightening nuts, now, be provided with spring 10, sealing cover 9 mechanism owing to expanding in female 3, can selfsealings be realized; When offtake 2 need be expanded, the internal thread 8 that the outside thread 11 offtake 2 being expanded male 5 and major joint 1 expand female 3 is aimed at and is screwed up, when being screwed to last section, offtake 2 boss 12 expanded on male 5 end face can be pushed major joint 1 open and expand sealing cover 9 in female 3, and then, realize being communicated with by the breach 13 on boss 12 between major joint 1 with offtake 2, as shown in Figure 4; When offtake 2 need be expanded again, as long as dock toward the expansion female 3 of previous offtake 2.
