【Detailed ways】

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figures 1 to 6, a quick joint structure includes a joint body 1 that can be inserted into the insertion tube. The joint body 1 is connected with a fixing seat 2, and the fixing seat 2 is provided with a The elastic clamping part 3 used to clamp the insertion tube behind the joint body 1, the housing 4 that can slide relative to it is sleeved on the said fixing base 2, and the inner wall of the said housing 4 is provided with Press the elastic clamping part 3 so that the elastic clamping part 3 clamps the first protruding part 41 of the insertion tube. When the housing is in the initial position, the first protruding part of the inner wall of the housing presses against the elastic clamping part and then clamps the insertion tube. In the clamped state, the insertion tube cannot be pulled out at this time. The fixed seat 2 is provided with a first shrapnel 5 that can bounce the shell 4 back to the initial position after sliding relative to the fixed seat 2. The shell 4 of the described The inner wall is provided with a second protruding part 42 that can slide and fit with the first elastic piece 5. The second protruding part presses the first elastic piece to further bend the first elastic piece, and quickly unlocks the insertion tube. Return to the initial position under the reaction force of a shrapnel, quickly pop up the shell, one end of the joint body is connected to the quick male buckle of the faucet or water gun, and the other end is used to connect the water pipe; the quick joint structure of the present invention uses the first shrapnel to replace the original The unique spring structure can quickly pop up the shell, which saves cost and simplifies the structure. Moreover, the upper end of the first shrapnel is bent inward to cooperate with the shell to avoid breakage during long-term use. The design is reasonable and can prolong the service life.

As shown in Figures 1 to 6, in this embodiment, the end of the first elastic piece 5 is bent inward, and the surface of the second protruding portion 42 is an arc matching the outer side of the end of the first elastic piece 5. surface, the shell slides, the second protruding part presses the first shrapnel to bend inward, and the rebound force is stronger. When the shell is loosened, the first shrapnel rebounds under the action of its own elastic force, which produces a reaction force on the shell and restores the shell. To the initial position, quick rebound is realized, and the end of the first elastic piece 5 is bent inwardly to reduce the sliding resistance of the casing, so that the first elastic piece will not be broken after long-term use, and the service life is prolonged.

As shown in FIG. 1 to FIG. 6 , in this embodiment, the number of the first elastic pieces is three, which are arranged on the fixing seat in the circumferential direction, and the springback effect is good.

As shown in Figures 1 to 6, in this embodiment, the elastic clamping part 3 includes a plurality of second elastic pieces 31 connected to the fixing seat 2 and extending vertically, and the upper ends of the second elastic pieces 31 are bent A clasp 32 for locking the insertion tube is provided, and the joint body 1 is provided with an opening 11 through which the clasp 32 can pass; when the shell is in the initial position, the first protrusion 41 presses the clasp 32, The hook 32 clamps the insertion tube after passing through the opening 11; when the housing is slid, the first protrusion 41 is away from the hook 32, and the hook pops out from the opening 11, releasing the insertion tube. In this embodiment, the number of clasps is 3, which are evenly distributed in the circumferential direction, so as to better clamp the insertion tube.

As shown in FIGS. 1 to 6 , in this embodiment, the fixing base 2 is also vertically provided with a plurality of limiting pieces 21 connected with the connector body 1 and capable of restricting the sliding of the housing 4 . The further sliding of the shell can be restricted to play the role of limit.

As shown in Figures 1 to 6, in this embodiment, one end of the joint body 1 extends outward to form a boss 14 that can prevent the shell 4 from falling off, and the second protrusion 42 abuts against the boss 14 and the interface. The step formed by the body 1 prevents the shell from popping up when the body 4 returns to the initial position.

As shown in Figures 1 to 6, in this embodiment, the outer wall of the joint body 1 is provided with ribs 12, and the limiting piece 21 is provided with a groove for the ribs 12 to snap into, and the ribs Engaging with the groove makes the fixing seat 2 fixedly connected to the joint body 1, preventing the fixing seat from sliding together with the shell.

As shown in Figures 1 to 6, in this embodiment, one end of the joint body 1 is provided with a water pipe interface 13, and the joint body 1 is connected with a water pipe for locking the water pipe after the water pipe is connected to the water pipe interface 13. The swivel cover 6, when in use, first connect the water pipe to the water pipe interface 13, then rotate the swivel cover 6 to fix it.

As shown in FIG. 1 to FIG. 6 , in this embodiment, the fixed seat 2 , the elastic clamping portion 3 and the first elastic piece 5 are integrally formed as an integral structure, and the structure is stable.
