Description

Technical Field

[0001] The utility model relates to the technical field of electrical control cabinets, and particularly relates to a detachable-filter electrical control cabinet. Background Art

[0002] An electrical control cabinet is a cabinet made of steel materials to protect components to work normally. The manufacturing materials of the electrical cabinet are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. The cold-rolled steel plate is relatively softer in material and more suitable for the manufacture of electrical cabinets. The electrical cabinet has a wide range of applications and is mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. There are ventilation openings on the electrical control cabinet, and filters are usually arranged in the ventilation openings to block dust and sundries outside the control cabinet. The filter is generally connected to the electrical control cabinet by bolts. After the filter is fixed, if it needs to be removed for cleaning or replacement, tools such as screwdrivers are required, which is not convenient for the quick disassembly and subsequent installation of the filter. Therefore, a detachable-filter electrical control cabinet is proposed to facilitate the disassembly and installation of the filter. Content of the Utility Model

During installation, after placing the filter screen in the support, rotate the pressing frame. The pressing frame squeezes the filter screen. Pull the connecting block. After sleeving the clamping seat on the ends of the two clamping blocks away from the blocking seat, slide the clamping seat towards the blocking seat. After the convex block is inserted into the blocking seat, release the connecting block. The spring pushes the insertion block towards the convex block, and finally the insertion block is inserted into the slot on the side wall of the convex block, which facilitates the fixing of the clamping seat.

[0006] Specifically, stoppers are integrally formed on both sides of the two supports.

[0007] By adopting the above technical solution, the setting of the stoppers can block the gap between the support and the pressing frame.

[0008] Specifically, a plurality of anti-slip protrusions are integrally formed on both sides of the two clamping seats.

[0009] By adopting the above technical solution, the setting of the anti-slip protrusions facilitates holding the clamping seat, and thus is conducive to the taking and placing of the clamping seat.

[0010] Specifically, handles are fixed on the side walls of the two pressing frames away from the cabinet body.

[0011] By adopting the above technical solution, holding the handle facilitates pulling the pressing frame to rotate.

[0012] Specifically, a plurality of reinforcing bars are integrally formed in the two pressing frames.

[0013] By adopting the above technical solution, the setting of the reinforcing bars can improve the strength of the pressing frame.

[0014] Specifically, a plurality of positioning columns are integrally formed in the two supports.

[0015] By adopting the above technical solution, the setting of the positioning columns is conducive to the positioning of the filter screen.
