DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0025] Referring to Figs. 1-6 The utility model provides a detachable car door panel buckle, including main part 1, the bottom of inside main part 1 has the buckle part 4 of movable, buckle part 4 adopts several independent pawls, and every independent pawl can move synchronously, the upper portion of inside main part 1 still is provided with the guiding assembly 3 of the up and down movement, when guiding assembly 3 moves down, every independent pawl in buckle part 4 can move away from the axle position of main part 1, when guiding assembly 3 moves up, every independent pawl in buckle part 4 can contract to the axle position of main part 1. The top of main part 1 is provided with top cover 2 through screw thread, and guiding assembly 3 can move in top cover 2.

[0026] Buckle part 4 is composed of several independent pawls, and the pawls can move synchronously. When the pawls move away from the axle position of main part 1, they can be clamped into the holes on the automobile door panel sheet metal, realizing the close connection of the buckle and the door panel. When the pawls contract to the axle position of main part 1, the pawls are separated from the door panel holes, facilitating the disassembly of the buckle from the door panel for maintenance or replacement of the door panel.

[0027] A conical guide 41 is arranged on the top of buckle part 4. When guiding assembly 3 moves down, it will act on the conical guide 41, thereby moving the independent pawls in buckle part 4 outward, and finally making the pawls of buckle part 4 clamped into the sheet metal holes. This structure design effectively solves the problem of easy breakage of the traditional buckle part 4, and improves the service life and reliability of the buckle.

[0028] Embodiment one: referring to Figs. 1-4 The guiding assembly 3 includes a guiding rod 31 that can slide up and down in the main part 1. The bottom of the guiding rod 31 is fixed with a first guiding block 312, and the diameter of the lower end of the first guiding block 312 is smaller than that of the upper end. A first handle 311 is fixed on the top of the guiding rod 31. When the first handle 311 is pressed, the first guiding block 312 can drive every independent pawl in the buckle part 4 to move. The guiding assembly 3 also includes a support block 313 near the first guiding block 312. The guiding assembly 3 also includes a first spring 314 that is sleeved on the guiding rod 31. One end of the first spring 314 is in contact with the support block 313, and the other end is in contact with the bottom of the top cover 2.

[0029] The operator presses the first handle 311, which drives the guide rod 31 to move downward. When the guide rod 31 moves downward, the first guide block 312 moves downward as well. Since the diameter of the lower end of the first guide block 312 is smaller than that of the upper end, the first guide block 312 exerts an outward pushing force on the clamping claws in the clamping portion 4, causing the clamping claws to move away from the axial position of the main body 1. The first spring 314 provides a continuous elastic force to keep the clamping claws in the clamping portion 4 in the same position.

[0030] Embodiment Two: Reference Figs. 5-6 As shown, the center of the inner part of the top cover 2 is provided with an internal thread, and the guide assembly 3 further includes a threaded rod 32 which is engaged with the internal thread in the top cover 2. The bottom of the threaded rod 32 is connected with a second guide block 322, the diameter of the lower end of the second guide block 322 is smaller than that of the upper end, and the top of the threaded rod 32 is further connected with a second handle 321. When the second handle 321 is rotated to make the threaded rod 32 move downward, the second guide block 322 can move each independent clamping claw in the clamping portion 4.

[0031] The operator rotates the second handle 321. Since the threaded rod 32 is engaged with the internal thread in the top cover 2, according to the principle of threaded transmission, the threaded rod 32 will move downward along the axial direction. The downward movement of the threaded rod 32 drives the second guide block 322 to move downward, which exerts an outward pushing force on the clamping claws in the clamping portion 4, causing the clamping claws to move away from the axial position of the main body 1. When the clamping claws are clamped into the metal plate hole, the clamping operation is completed.

[0032] The top of each independent clamping claw in the clamping portion 4 is provided with a tapered guide 41, and the inner part of the main body 1 near the bottom is further provided with a plurality of sliding grooves 11, and each independent clamping claw of the clamping portion 4 is further provided with a sliding rail 42 which cooperates with the sliding groove 11. The sliding groove 11 is further provided with a second spring 5 which can reset each independent clamping claw of the clamping portion 4. The bottom of the main body 1 is further provided with a ring groove 12 which contains a sealing ring 6.

[0033] If the clamping buckle needs to be disassembled, the guide assembly 3 moves in the opposite direction, and the second spring 5 pushes the clamping claws to contract towards the axial position of the main body 1 under the action of its own elastic force, achieving automatic resetting of the clamping claws for the next use.

[0034] When the guide assembly 3 moves upward, it will separate from the clamping portion 4. At this time, the second spring 5 will move the independent clamping claws in the clamping portion 4 towards the center position of the main body 1 under the action of its own elastic force, so that the clamping claws of the clamping portion 4 are pulled out of the metal plate hole, facilitating the replacement of the decorative plate and improving the efficiency of disassembly and maintenance.

[0035] The above embodiment only expresses one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
