Safe self-locked quick joint

Abstract

The invention discloses a safe self-locked quick joint which comprises a first pipe joint and a second pipe joint. A leakage-proof inner sleeve plate is arranged on the side, close to the second pipejoint, in the inner part of the first pipe joint; an annular straight slot is formed in the side wall of one side, close to the leakage-proof inner sleeve plate, of the first pipe joint; an annular sliding plate is slidably connected in an annular chute; more than our column slots which are symmetrically distributed at equal angles are formed in the side wall of the outer side, close to the annular sliding plate, of the first pipe joint; cover plates are arranged on the sides of the outer parts, close to the column slots, of the first pipe joint; the cover plates are connected to the first pipe joint through inside hexagonal bolts; self-locked clamping columns are arranged in the lower sides of the column slots; and semi-circular chutes formed in one sides of the lower ends of the self-locked clamping columns in sliding fit to an inclined chute and a smooth chute formed in one side of the second pipe joint are in fit connection to self-locked clamping slots, so that the first pipe joint and the second pipe joint are self-locked safely.

Description

technical field [0001] The invention relates to the technical field of quick connectors, in particular to a safety self-locking quick connector. Background technique [0002] A pipeline is a device used to transport gas, liquid and fluid with solid particles connected by pipes, pipe connectors and valves. At present, in various pipeline connections, in order to facilitate the arrangement and installation of pipes, conduits are often used The joint realizes steering and connection, but the existing joint cannot realize fast and safe self-locking, the sealing performance is not good, it cannot realize quick connection, it is not easy to disassemble, and the flow of the medium cannot be controlled during use, such as the patent application publication number 201220728791.6 disclosed A safety self-locking quick connector, including a quick-connect outer cover and connecting screws, an inner sleeve is provided on the inner wall of the quick-connect outer cover, and a first spring...

[0002] A pipeline is a device used to transport gas, liquid and fluid with solid particles connected by pipes, pipe connectors and valves. At present, in various pipeline connections, in order to facilitate the arrangement and installation of pipes, conduits are often used The joint realizes steering and connection, but the existing joint cannot realize fast and safe self-locking, the sealing performance is not good, it cannot realize quick connection, it is not easy to disassemble, and the flow of the medium cannot be controlled during use, such as the patent application publication number 201220728791.6 disclosed A safety self-locking quick connector, including a quick-connect outer cover and connecting screws, an inner sleeve is provided on the inner wall of the quick-connect outer cover, and a first spring is set on the inner cover, and the quick-connect outer cover and the inner sleeve move relative to each other in the axial direction. There is a ball valve between the quick-connect outer casing and the connecting screw. One end of the ball valve is sealed and connected to the inner casing, and the other end of the ball valve is sealed and connected to the connecting screw through a sealing device. However, the above patents cannot achieve fast and safe self-locking during use. Poor sealing performance, unable to achieve quick connection, not easy to disassemble
