Abstract

The invention relates to an anti-drop fast connector. The anti-drop fast connector comprises a male plug and a female plug, wherein external threads are formed in the male plug, and internal threads are formed in the female plug; the male plug is divided into a fixed component and a movable component, a plurality of grooves are formed in the fixed component in the axial direction, and the movable component is arranged in the grooves; the external threads comprise fixed threads and movable threads, wherein the fixed threads are positioned in the fixed component, the movable threads are positioned in the movable component, and springs are arranged at the bottom of the movable component. Through the adoption of the structure of the anti-drop fast connector disclosed by the invention, the movable threads and the fixed threads are combined, the drop of the threads can be effectively avoided, the fixed threads and the movable threads are aligned and screwed during use, and after screwing in, the fixed threads and the movable threads are staggered, so that the purpose is achieved.

Description

A kind of Drop-proof fast connector
Technical field
The present invention relates to the quick interconnection technique field of pipeline, especially relate to a kind of Drop-proof fast connector.
Background technique
In mechanical design field, many places need to adopt screw thread to connect, because function is different, and the non-dismountable connection of the needs that some needs detachably have, when removably connecting, under vibration, there will be the phenomenon that screw thread comes off, if adopt non-dismountable structure, destructive dismounting is needed when maintenance, need again to offer screw thread when installing afterwards to connect, will greatly affect engineering time and the working life of product like this, waste a large amount of artificial and resources.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly can not needs to adopt destructive dismounting can reach the Drop-proof fast connector preventing from coming off.
The present invention solves the technological scheme that its technical problem takes: a kind of Drop-proof fast connector, comprise male plug and female plug, described male plug is provided with outside thread, internal thread is provided with in described female plug, described male plug is divided into fixed block and movable part, described fixed block has offered some grooves in the axial direction, described movable part is arranged in groove, described outside thread comprises retaining thread and movable whorl, described retaining thread is positioned on fixed block, described movable whorl is positioned on movable part, spring is provided with in the bottom of described movable part.
Concrete further, the axial direction of the internal thread of described female plug arranges some grooves.
Concrete further, described movable part comprises loose collar, described loose collar protrudes upward some equidistant external parts, arranges movable whorl at the outer surface of described external part, bottom described loose collar, arrange spring.
Concrete further, described fixed block comprises fixed block body, and described groove is arranged on fixed block body, and described external part is positioned at groove, and described fixed block body lower part is provided with the annular groove placed for loose collar.
The invention has the beneficial effects as follows: after have employed said structure, by adopting the combination of movable whorl and retaining thread, can effectively prevent screw thread from coming off, by retaining thread and movable whorl alignment when using, screw in, after screw-in, retaining thread and movable whorl are staggered, achieve the goal.

Embodiment
Below in conjunction with accompanying drawing, the present invention is explained in detail.
A kind of Drop-proof fast connector as depicted in figs. 1 and 2, comprise male plug 2 and female plug 1, described male plug 2 is provided with outside thread, internal thread 11 is provided with in described female plug 1, described male plug 2 is divided into fixed block 21 and movable part 22, described fixed block 21 has offered some grooves 212 in the axial direction, described movable part 22 is arranged in groove 212, described outside thread comprises retaining thread 211 and movable whorl 223, described retaining thread 211 is positioned on fixed block 21, described movable whorl 223 is positioned on movable part 22, spring 3 is provided with in the bottom of described movable part 22, the axial direction of the internal thread 11 of described female plug 1 arranges some grooves 12, described movable part 22 comprises loose collar 221, and described loose collar 221 protrudes upward some equidistant external parts 222, arranges movable whorl 223 at the outer surface of described external part 222, bottom described loose collar 221, arrange spring 3, described fixed block 21 comprises fixed block body, and described groove 212 is arranged on fixed block body, and described external part 222 is positioned at groove 212, and described fixed block body lower part is provided with the annular groove 213 placed for loose collar 221.
When using, manually by movable part 22 pull-up Compress Spring 3, movable whorl 223 on the external part 222 of movable part 22 is alignd with the retaining thread 211 on fixed block 21, after screwing in female plug 1, unclamp movable part 22, spring 3 drives the movable whorl 223 on movable part 22 to stagger with retaining thread 211, movable whorl 223 just in time keeps off on the internal thread 11 of female plug 1, prevent female plug 1 from dropping, structure is simple, uses efficient and convenient.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
