However, most cabinets are integrated cabinets. The integrated cabinets have a small internal installation space and the internal cables are arranged in a messy manner. When installing and testing the wires, it is inconvenient for operators to swing handheld instruments inside the cabinet, and the use of testing instruments inside the cabinet is also limited by the narrow space and the messy cable arrangement, which is inconvenient. Therefore, the present application designs a variable frequency exhaust control device to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example: See Figure 1-5 The utility model discloses a variable frequency exhaust control device, comprising a placement cabinet 2, an exhaust control device 4 is arranged inside the placement cabinet 2, a side end of the placement cabinet 2 is abutted against a support plate 1, and a cover plate 5 is hingedly connected to the other side end of the placement cabinet 2, a side panel 3 is arranged on the outer side of the side wall of the placement cabinet 2, and a fixing seat for limiting and supporting the placement cabinet 2 is arranged between the support plate 1 and the placement cabinet 2. Through the arrangement of the side panel 3, the space for observation and maintenance can be increased by disassembling and assembling the side panel 3, so as to facilitate the detection and installation of the wires on the connecting column 7; two mounting grooves 6 for clamping the fixing seat are symmetrically arranged on the side wall of the placement cabinet 2, and through the arrangement of the mounting groove 6, the placement cabinet 2 can be better installed and fixed on the fixing seat; the fixing seat is composed of a limiting connecting plate 10 and a limiting protrusion 11, and a plurality of fixing bolts for fixing the limiting connecting plate 10 are symmetrically arranged on the limiting connecting plate 10. Through the arrangement of the limiting connecting plate 10 and the fixing bolts, the limiting connecting plate 10 can be better fixed on the supporting plate 1, so as to stably install the placement cabinet 2.

[0021] In the present invention, the limiting protrusion 11 is obliquely protruded on the limiting connecting plate 10, and the limiting protrusion 11 is engaged with the mounting groove 6. By setting the inclined mounting groove 6 and the inclined limiting protrusion 11, the placement cabinet 2 can be better fixed to prevent the placement cabinet 2 from sliding on the fixed seat and causing the placement cabinet 2 to fall; the side wall of the placement cabinet 2 is provided with a fixing groove 8 for installing the side panel 3, and the side end of the exhaust control device 4 is provided with a plurality of connection columns 7 for connecting the wires, and the side panel 3 is provided with a threading hole 1 for threading the wires. 2. By setting the threading hole 12, the wires can be better combined into one place, so as to prevent the scattered distribution of the wires from affecting the detection and maintenance of the wires; a number of bolt holes 9 are symmetrically provided on the side wall of the placement cabinet 2, and a number of limit bolts for threaded connection with the bolt holes 9 are symmetrically provided on the side plate 3. Circular chamfers 13 are symmetrically provided at both ends of the threading hole 12. By setting the circular chamfers 13, the wires can be better threaded and the scratches of the wires when passing through the threading hole 12 can be reduced, thereby improving the service life of the wires.

[0022] Working principle: When the utility model is used, the fixing seat is first installed on the support plate 1 by fixing bolts. When the fixing seat is installed, the limiting protrusion 11 at the side end of the limiting connecting plate 10 is tilted upward, and then the installation groove 6 and the limiting protrusion 11 are snapped together. The inclined installation groove 6 and the inclined limiting protrusion 11 can better fix the placement cabinet 2 to prevent the placement cabinet 2 from slipping on the fixing seat and causing the placement cabinet 2 to fall. The placement cabinet 2 is installed on the side end of the support plate 1, and then the side panel 3 is removed from the placement cabinet 2. Then, each wire is passed through the threading hole 12, and then each wire is linearly connected to the connecting column 7. Then, the side panel 3 is slid to the side end of the placement cabinet 2, and the side panel 3 is fixed to the side wall of the placement cabinet 2 through the threading bolt and the bolt hole 9. The wires are tightened and located at the threading hole 12. At this point, the installation of the variable frequency exhaust control device is completed.
