Description
Technical field
The utility model relates to joint field, particularly relates to a kind of offtake.
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 offtake that can infinitely expand.
To achieve these goals, the utility model is by the following technical solutions: a kind of offtake, comprise block and joint body, described joint body 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 internal thread outside described expansion female, be provided with sealing cover inside internal thread, sealing cover is by spring compresses shutoff screw mouth; 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 sealing of described block one end, block is inner to be provided with and the internal thread expanded male outside thread and mate, is provided with seal ring inside screw thread of blocking a shot.
As preferably, inside described spring, be provided with the retaining post of sealing cover.
As preferably, outside described block, be provided with the ear mechanism be convenient to hand and twisted.
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) is expanded female and had self-sealing function, novel structure; (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 offtake, see Fig. 1, Fig. 2, comprises block 1 and joint body 2, described joint body 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, and expand male 5 and expand female 3 to be oppositely arranged; Expand male 5, expansion female 3 is 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 16 of sealing cover 9 is provided with inside described spring 10, make sealing cover 9 to press down certain distance, retaining post 16 is one-body molded with expansion female 3, also for restraining spring 10 position; Be provided with outside described expansion male 5 and the outside thread 13 expanded female 3 internal thread 8 and mate, end face is provided with boss 14, and for strutting the sealing cover 9 expanded in female 3, boss 14 is provided with breach 15, as shown in Figure 3; The sealing of described block 1 one end, 1 inside of blocking a shot is provided with and the internal thread 8 expanded male 5 outside thread 13 and mate, is provided with seal ring 12 inside 1 screw thread of blocking a shot, can shutoff expansion male 5 better; The ear mechanism 11 be convenient to hand and twisted also is provided with outside described block 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 offtake is used alone, block 1 that the expansion male 5 of joint body 2 is screwed on, owing to blocking a shot, 1 inside is provided with seal ring 12, shutoff preferably can expand male 5; On the tracheae of required docking, overlap upper cap nut again, be then connected on the input termination 6 of major joint 1 both sides air pipe connector 4 respectively, tightening nuts is fixed, and now, is provided with spring 10, sealing cover 9 mechanism, can realizes selfsealings owing to expanding in female 3; When joint need be expanded, the internal thread 8 that the outside thread 13 second joint body 2 being expanded male 5 and first joint body 2 expand female 3 is aimed at and is screwed up, when being screwed to last section, second joint body 2 boss 14 expanded on male 5 end face can be pushed first joint body 2 open and expand sealing cover 9 in female 3, and then, realize being communicated with by the breach 15 on boss 14 between two joint bodies 2, as shown in Figure 4; When joint body 2 need be expanded again, the like.
