Capacitors, resistors, and filters can only be arranged in depth on both sides of the magnetic devices or up and down.

[0004] In the prior art, the filter is generally installed in the filter cabinet by means of studs and nuts. Since the distance between the mounting frame and the cabinet body in the filter cabinet is limited, it is troublesome for the staff to tighten the nuts when installing the filter, and it is also difficult to disassemble it for subsequent maintenance.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses a quick-install structure for filter installation, referring to Figure 1-3 , including a mounting plate 1 and two symmetrically arranged clamping assemblies 2, the clamping assembly 2 includes a base 21, a pressure block 22, a rotating arm 23 with a locking head, a spring 24, a guide rod 25 and a friction block 26, the base 21 is fixed on the mounting plate 1, the guide rod 25 is vertically fixed on the base 21, the pressure block 22 moves along the guide rod 25, the spring 24 is arranged between the pressure block 22 and the base 21, the rotating arm 23 with a locking head is hinged on the pressure block 22, and the friction block 26 is fixed on On the base 21, the rotating arm 23 with a locking head can be self-locked with the friction block 26. Specifically, the rotating arm 23 with a locking head includes an integrally formed arm body 231 and a cam body 232. A limiting groove 261 is provided on the surface of the friction block 26. The cam body 232 can be frictionally self-locked with the limiting groove 261. A pad 27 is also fixed at a position corresponding to the pressure block 22 on the base 21. In order to ensure that the filter can be pressed, a rubber pad is fixed on the surface of the pad 27.

[0027] A mounting hole is provided in the middle of the mounting plate 1, and a fan 3 is fixed in the mounting hole. The fan 3 can improve the heat dissipation effect of the filter.

[0028] Reference Figure 2 The spring 24 is sleeved on the surface of the guide rod 25, and the top of the spring 24 can abut against the pressure block 22. The top of the guide rod 25 extends out of the pressure block 22. The top of the guide rod 25 is threadedly connected with a locking nut 4. By turning the position of the locking nut 4, the position of the pressure block 22 can be adjusted to adapt to the use of filters of different thicknesses.

[0029] The implementation principle of a quick-install structure and a filter cabinet for filter installation in the embodiment of the present application is as follows:

[0030] When installing the filter, it is only necessary to place the filter on the pads 27 on both sides, and clamp the filter with the clamping components 2 on both sides. When the clamping component 2 is working, it is only necessary to move the arm body 231 in the rotating arm 23 with a locking head upward, and the arm body 231 drives the cam body 232 to frictionally clamp in the limiting groove 261 of the friction block 26 to complete self-locking. In this process, the pressing block 22 moves downward to clamp the filter housing on the pad 27, and the installation is relatively simple.

[0031] Similarly, when removing the filter, it is only necessary to push the arm 231 downward to separate the cam body 232 from the friction block 26, and the spring 24 drives the pressing block 22 to return to its original position, so that the filter can be easily removed.

[0032] The present application also discloses a filter cabinet equipped with the above-mentioned quick-install structure for filter installation, referring to Figure 4 , including a cabinet body 5 , a mounting frame 6 is fixed inside the cabinet body 5 , and a mounting plate 1 is fixed on the mounting frame 6 .

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
