According to this embodiment, the filter screen 21 can be quickly disassembled and assembled by the locking mechanism 3, so that the filter screen 21 can be cleaned or replaced conveniently, and the working efficiency can be improved.

Referring to fig. 4 and 6-8, in some embodiments, the locking mechanism 3 includes a housing 31, a clamping assembly 32, a stop lever 33, and an end cap 34, the clamping assembly 32 is disposed within the housing 31, one end of the stop lever 33 extends in the second direction and through the housing 31, the clamping assembly 32 is configured to clamp or move away from the stop lever 33, and the end cap 34 is disposed on the housing 31.

Illustratively, the housing 31 is secured to the frame 2; for example, the metal plate is fitted into a hole of the housing 2 or fixed by a bolt or the like. The shape of the housing 31 is the same as the shape of the three-way pipe fitting. The end cap 34 is "mountain" shaped.

According to this embodiment, when the end cap 34 is moved toward the housing 31, a pressing force can be applied to the clamping assembly 32 to effect clamping of the stopper rod 33 by the clamping assembly 32. When the end cover 34 moves away from the shell 31, the clamping assembly 32 moves away from the limiting rod 33 due to the property of the clamping assembly, so that the limiting rod 33 can move freely.

Referring to fig. 4 and 6-8, in some embodiments, end cap 34 is threadably coupled to housing 31.

According to this embodiment, by doing so, not only can the disassembly and assembly of the end cap 34 be facilitated, but also the pressing force can be continuously applied to the clamping assembly 32 when the end cap 34 is connected with the housing 31.

Referring to fig. 4 and 6 to 8, in some embodiments, the clamping assembly 32 includes a first semicircular shaft 321, a second semicircular shaft 322, a guide rod 323 and an elastic portion 324, where the first semicircular shaft 321 and the second semicircular shaft 322 are symmetrically disposed along a radial direction of the stop lever 33, the first semicircular shaft 321 is fixed to the housing 31, the guide rod 323 is at least one pair, the pair of guide rods 323 are disposed between the first semicircular shaft 321 and the second semicircular shaft 322, each guide rod 323 is provided with the elastic portion 324, and two ends of the elastic portion 324 are respectively abutted against the first semicircular shaft 321 and the second semicircular shaft 322.

Illustratively, the guide rod 323 may be fixed with the first semi-circular shaft 321, and a guide hole for the guide rod 323 to move is provided on the second semi-circular shaft 322; or the first semicircular shaft 321 is provided with a guide hole for the guide rod 323 to move, and the guide rod 323 is fixed with the second semicircular shaft 322. The elastic portion 324 may be a spring or an elastic rubber pad, etc.

According to this embodiment, when the end cap 34 moves toward the first semicircular shaft 321, the end cap 34 applies a pressing force to the second semicircular shaft 322, so that the second semicircular shaft 322 moves toward the first semicircular shaft 321, and the first semicircular shaft 321 and the second semicircular shaft 322 may interact to clamp the stopper 33. During this time, the elastic portion 324 deforms. When the end cover 34 moves away from the first semi-circular shaft 321, the second semi-circular shaft 322 can be pushed to be automatically away from the first semi-circular shaft 321 by the extension of the elastic part 324.

Illustratively, the base may be manufactured from a metallic material or the like.

According to this embodiment, the foundation is embedded in the soil during construction. Moreover, the supporting strength of the base can be ensured by the materials.

Specifically, the working principle of the frequency converter control cabinet is as follows: when air enters the cabinet body 1 from each air inlet 12, the filter screen 21 filters the air so as to avoid sundries from affecting the normal operation of the frequency converter. The air then enters the cabinet 1 and flows upwards to take away the heat in the cabinet 1, and the heat dissipation can be accelerated by the fan 111. When the filter screen 21 is installed, the limiting rod 33 sequentially penetrates through the frame body 2 and the holes of the filter screen 21, so that the limiting rod 33 can block the filter screen 21 from moving. When the end cap 34 moves toward the first semi-circular shaft 321, the end cap 34 applies a pressing force to the second semi-circular shaft 322, so that the second semi-circular shaft 322 moves toward the first semi-circular shaft 321, and the first semi-circular shaft 321 and the second semi-circular shaft 322 can interact to clamp the limit rod 33. During this time, the elastic portion 324 deforms. When the filter 21 is disassembled and assembled, the end cover 34 moves away from the first semicircular shaft 321, the second semicircular shaft 322 can be pushed to be automatically away from the first semicircular shaft 321 through the extension of the elastic part 324, and then the limiting rod 33 is pulled out to disassemble the filter 21.

The foregoing is only illustrative of the present utility model and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present utility model.
