Description

Technical Field

[0001] The utility model relates to the field of motor drivers, in particular to a dustproof motor driver. Background Art

[0002] Electrical cabinets are generally used at steel mills. Motor drivers are often installed in the electrical cabinets. Dust can easily enter the interior of the electrical cabinets through the gaps in the electrical cabinets. The contactors of the motor drivers in the electrical cabinets are affected by the dust, and failures occur frequently.

[0003] For example, patent number CN219917961U discloses a dustproof motor driver, which includes a contactor, lead wires, a box, a box cover, a contactor buckle cover and an epoxy resin layer. The box can be detachably connected to the inner wall of the electrical panel cabinet. The box is arranged in a horizontal direction. The box is hollow with an opening on one longitudinal side and closed on all sides. The contactor, contactor buckle cover, silicone layer and epoxy resin are all connected and arranged in the hollow interior of the box. The box cover can be tightly and detachably connected to one side opening of the box, and the box cover can cover the hollow interior of the box to form a sealed space.

[0004] The driver proposed in the above scheme is installed inside the box, but the installation structure between the box cover and the box is relatively simple, which makes it inconvenient to disassemble the box cover and the box; in addition, the side wall of the box is also provided with a lead-out wire through hole, and the internal sealing of the wire through the lead-out wire through hole is poor, which still causes dust to enter the inside of the box. Therefore, a dustproof motor driver is proposed. Utility Model Content

[0005] In view of the above problems existing in the existing dustproof motor driver, the present utility model is proposed.

[0006] Therefore, the utility model aims to provide a dustproof motor driver to solve the problems raised by the background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A dustproof motor driver comprises a driver body, a dustproof box is provided on the outside of the driver body, an opening is provided on one side of the dustproof box, and a box cover is provided at the opening, a mounting plate extending into the interior of the dustproof box is fixedly provided on the side wall of the box cover, and the driver body is fixedly mounted on the surface of the mounting plate; the side walls of the dustproof box and both sides of the opening are elastically provided with clamping rods, the side walls of the box cover are provided with clamping grooves matching the clamping rods, and a pressing rod extending outward is provided at one end of the clamping rod; a lead-out wire through hole is provided on the side of the dustproof box away from the box cover, and a dustproof rubber ring is fixedly provided inside the lead-out wire through hole.

[0009] Preferably, a cavity is provided on the side wall of the dustproof box, and a slider is provided inside the cavity, a spring fixedly connected to the cavity is fixedly provided on the side wall of the slider, one end of the clamping rod is fixedly connected to the side wall of the slider, and one end of the pressing rod is fixedly connected to the side wall of the slider.

[0010] Preferably, the clamping rod is an L-shaped rod, and the clamping groove is an L-shaped groove matched with the clamping rod.

[0011] Preferably, the end of the pressing rod located outside the dustproof box is provided with a round end.

[0012] Furthermore, a limiting block for clamping and limiting one side of the mounting plate is fixedly provided on the inner side wall of the dustproof box.

[0013] Preferably, the side wall of the dustproof box is provided with a dustproof heat dissipation port.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model is provided with a mounting plate, a clamping rod, a clamping groove and a pressing rod. When the driver body needs to be taken out from the inside of the dustproof shell, it is only necessary to push the pressing rods on both sides by hand, so that the two pressing rods push the two clamping rods to move until the clamping rods are moved out from the inside of the clamping grooves. At this time, the box cover can be pulled out from one side opening of the box body, and the driver body on the mounting plate is also pulled out, so that it is convenient to take out the driver body.

[0016] 2. The utility model is provided with a dustproof rubber ring, which can fill the wiring between the wiring and the lead-out wire through-hole, thereby improving the sealing of the wiring and preventing external dust from entering the interior of the box.

[0017] 3. The utility model is provided with a slider and a spring, and the spring can apply elastic force to the slider, so that the slider drives the clamping rod to move and tightly clamp with the clamping groove, so that the box cover and the box body can be firmly connected.
