Description
Affiliated technical field
The utility model relates to a kind of pipe fitting, specifically a kind of hard tube connection rapid pipe joint.
Background technique
At present, rapid pipe joint is that pipeline connects and to have brought many conveniently, solved a lot of inconvenience that brought when ordinary couplings connects, and novel rapid pipe joint constantly occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of novel Quick joint for hard tube, can realize easily connection and the dismounting of hard tube.
The utility model is achieved in that this Quick joint for hard tube comprises lock tube handle, left joint, the bar that furthers, step cover, right connector and rubber sealing boot; On described lock tube handle, there is outside thread; On described left joint, have an interior threaded hole, a lock tube handle is threaded connection on this interior threaded hole, also has a through hole and outside thread on left joint, and this outside thread is for connecting the bar that furthers; On described right connector, have an interior threaded hole, a lock tube handle is threaded connection on this interior threaded hole, also has a step, a through hole and outside thread on right connector, and this outside thread is used for connecting step cover; Described step has put internal thread, is threaded connection on right connector; On the described bar that furthers, have interior threaded hole and an interior step, the bar that furthers is threaded connection on left joint, and the interior step furthering on bar is placed between the step and step cover on right connector; Described rubber sealing boot has a through hole, has a step on through hole, and rubber sealing boot is placed in the through hole of left joint and the through hole of right connector.
The beneficial effects of the utility model: realize easily connection and the dismounting of hard tube.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural scheme of mechanism of the utility model Quick joint for hard tube.
Embodiment
Fig. 1 is the structural scheme of mechanism of the utility model Quick joint for hard tube.By figure, known, the utility model comprises lock tube handle 2, left joint 3, the bar 4 that furthers, step cover 6, right connector 8 and rubber sealing boot 10; On described lock tube handle 2, there is outside thread; On described left joint 3, have an interior threaded hole, a lock tube handle 2 is threaded connection on this interior threaded hole, also has through hole 11 and an outside thread on left joint 3, and this outside thread is for connecting the bar 4 that furthers; On described right connector 8, have an interior threaded hole, a lock tube handle 2 is threaded connection on this interior threaded hole, also has a step 7, through hole 9 and an outside thread, this outside thread to be used for connecting step cover 6 on right connector 8; On described step cover 6, there is internal thread, be threaded connection on right connector 8; On the described bar 4 that furthers, have interior threaded hole and an interior step 5, the bar 4 that furthers is threaded connection on left joint 3, and the interior step 5 furthering on bar 4 is placed between the step 7 and step cover 6 on right connector 8; Described rubber sealing boot 10 has a through hole, has a step 12 on through hole, and rubber sealing boot 10 is placed in the through hole 11 of left joint 3 and the through hole 9 of right connector 8.
The utility model is work like this: the pipe 1 that will connect inserts respectively in the through hole 11 of left joint 3 and the through hole 9 of right connector 8, step 12 on conflict rubber sealing boot 10, screw in lock tube handle 2 and push against pipe 1, the pipe 1 that will connect is connected with left joint 3 and right connector 8 respectively, and the interior step 5 furthering on bar 4 is placed between the step 7 and step cover 6 on right connector 8, the bar 4 that furthers is constant with right connector 8 relative positions, rotation further bar 4 make to further bar 4 and left joint 3 relative furthering under threaded function, can make that left joint 3 is relative with right connector 8 to further, so that the relative rubber sealing boot 10 of pipe 1 that will connect furthers, make it sealing.During dismounting, the further bar 4 outwarded winding is detachable pipe with lock tube handle 2.
In addition to the implementation, the present invention also has other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
