Description

Technical Field

[0001] This utility model relates to the field of switch box technology, and in particular to a switch box. Background Technology

[0002] Switch boxes are typically installed in power systems to centrally house circuit breakers, switches, protection devices, current transformers, and other equipment for circuit control, protection, and monitoring.

[0003] Since a variety of electronic components are concentrated inside the switch box, and these components work together, they generate a lot of heat. Therefore, existing switch boxes are equipped with heat dissipation structures. However, for some precision electronic components, external dust may interfere with their accuracy. The heat dissipation structure must be equipped with a filter. Over time, a lot of dust accumulates on the surface of the filter, which will affect the efficiency of the heat dissipation structure. At the same time, the filter installed on the switch box is inconvenient to remove for cleaning.

[0004] Therefore, it is necessary to invent a switch box to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a switch box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switch box, including a box body, with two first supports connected to the inner wall of the box body. The first supports have multiple threaded holes, and multiple second supports are connected to the first supports by bolts. The second supports have mounting grooves. Sliding grooves are provided on both sides of the box body, and a pull-out frame is placed in the sliding groove. A filter screen is connected to the inner side of the pull-out frame, and a pull rod is connected to one side of the pull-out frame. Ventilation openings are provided on both sides of the box body.

[0007] Preferably, the vent is connected to multiple reinforcing ribs.

[0008] Preferably, the front side of the box has an opening, a door is connected to the opening, and a handle is connected to one side of the door.

[0009] Preferably, the top and bottom of the box are provided with multiple wire holes, and wire hole covers are connected to the wire holes.

[0010] The technical effects and advantages of this utility model are as follows: By setting up a pull-out frame, a filter screen, and a pull rod for use, the presence of the filter screen can ensure that external dust will not enter the inside of the box under normal ventilation conditions. After the filter screen has been used for a period of time, the pull-out frame can be pulled out by the pull rod to clean or replace the filter screen before resetting it. This ensures that the heat dissipation function of the switch box can always be guaranteed to work normally, the filter screen will not be clogged and can be cleaned and used repeatedly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-6 The switch box shown includes a box body 1. Two first brackets 2 are connected to the inner wall of the box body 1. The first brackets 2 have multiple threaded holes. Multiple second brackets 3 are connected to the first brackets 2 by bolts. The second brackets 3 have mounting grooves for mounting electronic components. Slide grooves are provided on both sides of the box body 1. Pull-out frames 4 are placed in the slide grooves. Filter screens 5 are connected to the inner side of the pull-out frames 4. Pull rods 6 are connected to one side of the pull-out frames 4. Ventilation openings are provided on both sides of the box body 1.

[0020] Multiple reinforcing ribs are connected at the ventilation openings to enhance the strength of the enclosure.

[0021] An opening is provided on the front side of the enclosure 1, and a door 8 is connected to the opening. A handle 9 is connected to one side of the door 8, which allows for the inspection or disassembly of electronic components inside the enclosure 1.

[0022] Multiple wire holes are provided on the top and bottom of the housing 1. A wire hole cover 10 is connected to the wire hole for connecting external wire harnesses to electronic components inside the housing 1. The wire hole cover 10 ensures that dust will not enter the housing 1 through the wire hole.

[0023] The working principle of this utility model is as follows: The presence of filter screen 5 ensures that external dust will not enter the interior of the box 1 under normal ventilation conditions. After the filter screen 5 has been used for a period of time, the pull frame 4 can be pulled out by the pull rod to clean or replace the filter screen 5 and reset it.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
