Description

Frequency conversion cabinet

Technical Field

The utility model relates to the field of electrical equipment control, in particular to a frequency conversion cabinet.

Background

Most of the prior frequency conversion cabinets on the market have an air inlet filter screen, so that the outside flocculent sundries can be effectively prevented from entering the cabinet body after the filter screen is used, the normal work of the frequency converter is guaranteed, but most of the prior filter screens used by the frequency conversion cabinets are fixed by screws and are not easy to detach, and the frequency conversion cabinets are inconvenient in normal maintenance, so that the development of the frequency conversion cabinets with the filter screen capable of being quickly detached and installed is urgently needed to meet the development requirement.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a frequency conversion cabinet which is simple in structure and can be quickly disassembled and assembled by a filter screen.

The technical scheme of the utility model is as follows: a variable frequency cabinet which is characterized in that: a variable frequency cabinet which is characterized in that: comprises a cabinet body and an air inlet filtering component; the cabinet body is provided with an air inlet, and the air inlet filtering component is arranged at the air inlet; the air inlet filter assembly comprises a mounting bracket, a framework and a filter screen; the mounting bracket is of a square structure, and is provided with an air inlet through hole I and a framework mounting groove; the air inlet through hole I is communicated with the framework mounting groove and the air inlet; the framework comprises two installation guide inclined planes, and the framework is installed in the framework installation groove through the matching of the installation guide inclined planes and the guide inclined planes in the framework installation groove; a groove I is formed in the installation guide inclined plane and used for installing a sealing rubber strip; a through hole II is formed in the middle of the framework, and grooves II are formed in the periphery of the through hole II; the filter screen is installed on the groove II, and the filter screen seals the through hole II.

Further, the skeleton mounting groove is completely matched with the skeleton.

Further, the cross section of the framework is triangular or trapezoidal.

Further, a handle is arranged on the framework.

Further, the framework is made of alloy or iron materials.

Further, the cross-sectional dimension of the air inlet through hole I is smaller than that of the through hole II.

The utility model has the beneficial effects that: according to the air inlet filter assembly, the inclined plane is matched with the guide installation mode, the framework provided with the filter screen is directly installed into the framework installation groove from the upper portion of the support, installation can be completed under the action of self gravity, other locking mechanisms are not needed, installation is very convenient, when the air inlet filter assembly is detached, the framework is pulled up by holding the handle by hand, detachment operation can be completed, and detachment is very simple and convenient.
