[0004] The technical solution of this utility model:
[0005] An adjustable damping system includes a base I and a base II; the base I is disposed above the base II and connected to the base II via an elastic structure A; the base I is a structure that can move up and down; the base II is a structure that can be adjusted up and down.
[0006] Further refining the above technical solution, a notch is provided at the bottom of the base I, and the top of the base II is connected to the notch to serve a guiding function. Further refining the above technical solution, the base I and base II are plate-shaped; the adjustable damping system also includes a front cover plate and a rear cover plate, the front cover plate and the rear cover plate are connected, the base I is sandwiched between the front cover plate and the rear cover plate, the base II is sandwiched between the front cover plate and the rear cover plate, and the base II and the rear cover plate are connected by an adjustable snap-fit structure.
[0007] To further refine the above technical solution, a sliding platform is provided on the rear cover plate, and sliding grooves are provided on the substrate I and substrate II. The sliding platform and the sliding groove are connected in a cooperative manner to serve as guides.
[0008] Further refining the above technical solution, the elastic structure A consists of two tension springs, one on the left and one on the right; the front cover plate is provided with two observation windows, which are opposite to the tension springs; these windows can be used to observe the state of the tension springs.
[0009] Further refining the above technical solution, the adjustable buckle structure is embedded in the base II and consists of a left buckle, a right buckle, and an elastic structure B. The left buckle and the right buckle are opposite each other, and their front ends are pressing parts. The front ends of the left buckle and the right buckle extend into the adjustment window provided on the front cover plate, and the ends extend into the adjustment groove provided on the rear cover plate. Both sides of the adjustment groove are toothed. The left buckle and the right buckle are opened by the elastic structure under tension, and the ends are respectively locked between the teeth on both sides of the adjustment groove. The left buckle and the right buckle are closed by pressing the pressing part, and the ends are respectively withdrawn from the teeth on both sides of the adjustment groove.
[0010] Further refining the above technical solution, the elastic structure B is a compression spring.
[0011] Further refining the above technical solution, the adjustment groove is provided with buckle grooves on both sides, and the ends of the left and right buckles are provided with buckle plates, which are fastened in the buckle grooves; this can prevent the ends of the left and right buckles from coming out of the adjustment grooves; when installing the adjustable buckle structure, the left buckle, right buckle, and adjustable buckle structure are combined together. First, the ends of the left and right buckles are placed in the adjustment grooves, so that the buckle plates are in the buckle grooves, thus forming a stable whole. Then, the base II is fastened, so that the whole is embedded in the base II, completing the installation of the adjustable buckle structure, making the installation more convenient.
[0012] Further refining the above technical solution, the base II has a partial protrusion, which extends into the adjustment window set on the front cover and forms a central support for the front ends of the left and right latches; when the pressing part is pressed, the left and right latches are not easily deviated.
[0013] To further refine the above technical solution, the teeth on both sides of the adjustment groove are tilted downward at an angle of 1-5°; this can prevent the ends of the left and right latches from accidentally dislodging from between the teeth on both sides of the adjustment groove.
[0014] The advantages of this utility model are that it has a reasonable design and simple structure. Through the unique layout of the base I and the base II, and in conjunction with the tension spring (elastic structure A), the linkage between the base I and the base II is realized, providing a stable shock absorption effect.
