[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a buckle structure applied to a water pipe under a sink, comprising a pipe 9 and a convex ring 10, comprising a ring body 1, the inner wall of the ring body 1 is provided with a fixing component of the convex ring 10 for fixing the pipe 9, one side of the ring body 1 is movably connected with a cover body 3, the cover body 3 is provided with a card slot 5, the side of the ring body 1 away from the cover body 3 is fixedly connected with a buckle seat 6, and the buckle seat 6 is fixedly provided with a buckle 7 for engaging with the card slot 5.

[0021] Specifically, the inner walls of the cover body 3 and the buckle seat 6 are arc surfaces with the same curvature as the inner wall of the convex ring 1. The fixing components are two fixing strips 2 symmetrically arranged on the inner wall of the ring body 1, which improve the fit between the entire buckle structure and the pipe 9. The opposite inner walls of the two fixing strips 2 are respectively fitted with the convex rings 10 of the two pipes 9. The two pipes 9 are plugged in, and the convex rings 10 on the outer walls of the pipes overlap (this is the prior art). The two convex rings 10 are covered within the two fixing strips 2, thereby performing a good limit fixation on the pipe 9.

[0022] Specifically, the cover body 3 is rotatably connected to the ring body 1 through the bending piece 4, and the bending piece 4 is fixedly connected to the cover body 3 and the ring body 1 respectively. The bending piece 4 is a bending-resistant plastic, and the bending piece 4 can be bent multiple times without breaking. The ring body 1, the cover body 3, the buckle seat 6 and the buckle 7 are all made of elastic plastic, which makes it convenient for the ring body 1 to be mounted on the convex ring 10, and the elastic deformation of the buckle 7 is used to engage with the slot 5.

[0023] Specifically, the buckle 7 includes a guide plate 71 and a protrusion 72. The guide plate 71 is symmetrically provided with two outer walls that are far away from each other and respectively fit with the inner walls of the slot 5. The outer walls of the two guide plates 71 can pass along the inner wall of the slot 5, thereby improving the stability of the slot 5 during the buckling process. The protrusion 72 is fixed at one end of the two guide plates 71 that is far away from each other. The distance between the farthest ends of the two protrusions 72 is greater than the width of the slot 5, ensuring that the protrusion 72 can be snap-connected and fixed to the slot 5.

[0024] Specifically, the inner wall of the slot 5 fits with the side wall of the buckle seat 6, and both sides of the protrusion 72 are arranged with arc surfaces and are tangent to the guide plates 71, which facilitates the buckling of the cover body 3 and the buckle 7. After the ring body 1 is installed on the pipe 9, the cover body 3 is rotated to move in the direction of the buckle 7, and the two guide plates 71 fit the inner wall of the slot 5 and slide in until the inner wall of the slot 5 abuts against the protrusion 72. Under the action of pressure, the guide plates 71 are deformed so that the inner wall of the slot 5 can slide along the arc surface of the protrusion 72 until the inner wall of the slot 5 slides over the protrusion 72 and fits the side wall of the buckle seat 6. At this time, the inner wall of the cover body 3 fits the pipe. When the locking cam 72 is in the unlocking state, the locking cam 71 is in the unlocking state, and the locking cam 71 is in the unlocking state.

[0025] Specifically, a lever cover 8 is fixedly provided on the outer wall of the cover body 3 on one side close to the buckle seat 6 , and the cover body 3 can be easily moved by the lever cover 8 .

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, the two pipes 9 are plugged in, the convex rings 10 on the outer walls of the pipes overlap (this is the prior art), the ring body 1 is sleeved on the outside of the two convex rings 10, and the two convex rings 10 are covered within the two fixing strips 2, so that the pipes 9 are well limited and fixed, the cover body 3 is rotated to move in the direction of the buckle 7, and the two guide plates 71 slide in against the inner wall of the slot 5 until the inner wall of the slot 5 abuts against the protrusion 72. Under the action of pressure, the guide plate 71 is deformed so that the inner wall of the slot 5 can follow the protrusion 72. 2 until the inner wall of the slot 5 slides over the protrusion 72 and fits with the side wall of the buckle seat 6. At this time, the inner wall of the cover body 3 is in contact with the pipeline, and the outer walls of the cover body 3 on both sides of the slot 5 are against the blocks 72, thereby completing the installation of the buckle structure. When disassembling, the cover 8 is pulled outward with force to drive the cover body 3. The inner wall of the slot 5 acts on the protrusion 72 to deform the guide plate 71, so that the slot 5 slides along the arc surface of the protrusion 72 until it is separated from the protrusion 72, thereby unlocking the buckle structure and facilitating disassembly.
