[0039] like Figures 1 to 5As shown, a slide buckle assembly includes an elastic reset cover 100, a fastener 200 and a handle 300. An inclined straight channel 211 is provided inside the elastic reset cover 100. A rotating shaft 500 is placed horizontally inside the inclined straight channel 211. The rotating shaft 500 passes through the slide buckle assembly and is used for the elastic reset cover 100 to rotate externally. An elastic member is also provided on the elastic reset cover 100 to enable the elastic reset cover 100 to have an elastic reset function. The fastener 200 includes a guide portion 210 and a fastening portion 220. The guide portion 210 and the fastening portion 220 are bent and connected to form a bending angle. The guide portion 210 is arranged in the inclined straight channel 211 and can move linearly along the inclined straight channel 211. Under the action of the guide portion 210, the fastening portion 220 also moves linearly along the inclined straight channel 211. The guide part 210 is provided with a strip hole 212 arranged along the length direction of the inclined straight channel 211. The rotating shaft 500 is inserted into the strip hole 212 and can move relative to the strip hole 212 along the length direction of the inclined straight channel 211. The strip hole 212 limits the linear range of movement of the guide part 210. The fastening part 220 is provided with a buckle position 221. The guide part 210 is on the side facing away from the buckle position 221. Due to the existence of the bending angle, when the guide part 210 moves linearly along the inclined channel, the buckle position 221 is pushed outward and moves horizontally to the outside at the same time, and is separated from the original buckled place to make the fastener 200 disengaged. The mechanical disengagement method is adopted to complete the door release function, which is ingenious in design and simple in structure. The handle 300 is arranged on the elastic reset cover 100 and can push the elastic reset cover 100 to open away from the buckle position 221. The handle 300 is used to pull the elastic reset cover 100 to rotate.

[0040] In some embodiments of the present invention, guide posts 230 are provided on both sides of the guide portion 210. The guide posts 230 are laterally attached to the outer side surface of the guide portion 210 to limit the movement direction of the guide portion 210 and reduce the guiding friction generated by the guide portion 210 relative to the inner wall of the inclined straight channel 211. A guide groove 213 is provided on the inner wall of the inclined straight channel 211. The guide groove 213 is arranged along the movement direction of the guide portion 210. The guide groove 213 is a linear groove that can just accommodate the guide post 230. The guide post 230 is arranged in the guide groove 213 and can roll on the guide groove 213. In this embodiment, the guide groove 213 is provided with two groups, each group is composed of two parallel and opposite linear grooves arranged on the inner arm of the inclined straight channel 211. Each group of guide grooves 213 is installed with a guide post 230. The two ends of the guide post 230 are fixed across the two linear grooves of each group of guide grooves 213, so as to realize the guidance and movement of the guide portion 210 in the inclined straight channel 211.

[0041] Specifically, the guide portion 210 is provided with arc grooves 240 on both sides facing the guide groove 213. The arc grooves 240 are formed in the middle of the raised positions on both sides of the guide portion 210. The groove surface of the arc groove 240 is adapted to the cylindrical surface of the guide column 230, and the diameter and length thereof are the same. The guide column 230 is arranged on the arc groove 240 and can roll in the arc groove 240. The arc groove 240 restricts the guide column 230 to be outside the guide portion 210, and is sandwiched between the guide portion 210 and the inclined straight channel 211, thereby reducing the friction of the guide portion 210.

[0042] Both ends of the inclined straight channel 211 are provided with placement openings, and the fastener 200 enters the inclined straight channel 211 from the placement openings. A notch connected to the guide groove 213 is provided on the placement opening, and the guide column 230 enters the inclined straight channel 211 from the notch.

The handle 300 moves the elastic reset cover 100 from the outside, so that the fastener 200 rotates with the elastic reset cover 100 and disengages from the buckle plate 700.

[0045] In some embodiments of the present invention, the handle 300 has two connecting ears 310 rotatably connected to the rotating shaft 500, and the two connecting ears 310 are fixedly connected to the two sides of the elastic reset cover 100, so that the handle 300 and the elastic reset cover 100 are fixedly connected as one body, and the two can be formed by integral injection molding, and the two ends of the rotating shaft 500 pass through the elastic reset cover 100 and the connecting ears 310 respectively, and extend to the outside of the connecting ears 310, and are connected to the outside, so that the handle 300 and the elastic reset cover 100 are rotatably connected to the outside. In addition, the handle 300 and the elastic reset rod can also realize the function of toggling the elastic reset cover 100 and then toggling the fastener 200 to rotate by tightening, and the elastic reset cover 100 resets and pushes the handle 300 back and forth when resetting.

[0046] Furthermore, a return torsion spring 600 is installed on the rotating shaft 500, and the return torsion spring 600 presses against the handle 300 or the elastic return cover 100 to push the handle 300 or the elastic return cover 100 to rotate. Of course, the elastic return cover 100 and the handle 300 can also realize the return function through other return parts such as a tension spring, and the technical effect of the present invention can also be achieved.

[0047] Specifically, the edge of the lock is folded to one side to form an arc-shaped guide surface 710 with four sides folded inward, and the folding direction of the arc-shaped guide surface 710 is opposite to the insertion position of the fastener 200. The fastener 200 passes through the side of the lock containing the arc-shaped guide surface 710 and is fastened to the inner side of the lock. When the fastener 200 is fastened to the buckle plate 700, it smoothly transitions into the lock through the arc-shaped guide surface 710 and is finally fastened to the buckle plate 700.
