[0002] The air spring is mainly a spring component prepared by compressibility of air set in a sealed elastic space. Its structure is relatively simple, mainly composed of a sealed air elastic component and a cover component. The cover of the air spring is usually made of metal. The upper and lower ends of the air spring are limited by the cover, and the compressible range of the air spring is also limited. According to the requirements of the elastic regulation effect of the spring, the cover needs to be tightly connected to the two ends of the airbag to ensure that the airbag can maintain good air tightness inside during operation;

[0003] In order to facilitate the installation of the air spring cover, a conventional air spring cover is generally provided with a screw, and the screw cooperates with a nut to connect the cover to a fixed frame at a specified position;

[0004] In the prior art, the screw is generally assembled by directly welding the screw to the air spring cover. Although this can achieve a connection effect between the screw and the air spring cover to a certain extent, such an installation method causes the screw to be set upright on the cover for a long time and protrude too much from the cover. When the cover is transported, the protruding screw is very easy to be hit and broken, which seriously affects the installation effect of the cover at a later time. Summary of the invention

[0005] In order to solve the above technical problems, a high-strength air spring metal cover is provided, which solves the assembly problem of the screw in the prior art. Generally, the screw is directly fixed on the air spring cover by welding. Although it can achieve the connection effect between the screw and the air spring cover to a certain extent, such installation method causes the screw to be set upright on the cover for a long time and protrude too much from the cover. When the cover is transported, the protruding screw is very easy to be hit and broken, which seriously affects the installation effect of the cover in the later stage.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a high-strength air spring metal cover plate, comprising a metal cover plate body and a fixing bracket arranged on the top of the metal cover plate body, the fixing bracket is provided with a mounting hole, a fixing screw is passed through the mounting hole, a fixing nut abutting against the top surface of the fixing bracket is threadedly connected to the rod of the fixing screw, characterized in that a receiving groove is provided on the top surface of the metal cover plate body, a movable seat matched with the fixing screw is provided in the receiving groove, and a positioning piece for locking the movable seat is provided on the outer side of the metal cover plate body;

[0007] The movable seat comprises a rotating rod which is laterally rotatably arranged between the inner walls at the front and rear sides of the storage groove, and a rotating seat which is fixedly connected to the bottom end of the fixing screw rod is tightly sleeved on the rod body of the rotating rod.

[0008] Preferably, the positioning member includes a movable frame slidably arranged in an L shape on the outside of the metal cover body and an insertion rod vertically fixed on the inner wall of the movable frame, one end of the rotating rod is provided with a square positioning hole adapted to the insertion rod, and the outer wall of the metal cover body is provided with a through groove corresponding to the insertion rod, and the end of the insertion rod penetrates the through groove and extends into the square positioning hole.

[0009] Preferably, a connecting plate is horizontally arranged above the metal cover body, one end of the connecting plate is fixedly connected to the movable frame, and an inclined clamping plate is fixed to the other end of the connecting plate, and the clamping plate abuts against the top outer wall of the fixing nut.

[0010] Preferably, a locking screw is threadedly penetrated on the bottom surface of the movable frame, and a fixing screw hole matched with the locking screw is opened on the bottom surface of the metal cover body.

[0011] Preferably, the metal cover plate body is composed of a metal layer, a carburized layer and a galvanized layer, the carburized layer is located on the top surface of the metal layer, and the galvanized layer is located on the top surface of the carburized layer.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] (1) By setting the movable seat, the fixed screw can be pushed and pulled, and the storage groove, the rotating rod and the fixed screw can be rotated as a whole.
