Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch cabinets, specifically to an explosion-proof switch cabinet. Background Technology
[0002] Traditional switchgear cabinets use a hinged cover on one side and a lock on the other. While this design facilitates maintenance, in the event of a short circuit, the internal 10kW high-voltage current can cause an explosion. The force of the explosion can blow the traditional cover off, posing a significant danger. Therefore, an explosion-proof switchgear cabinet is needed that can be easily installed while preventing the cover from being blown off. Utility Model Content
[0003] The purpose of this utility model is to provide an explosion-proof switch cabinet.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] An explosion-proof switch cabinet is provided, including a cabinet body and a cover installed on the cabinet body. The cabinet body is provided with two side panels, and the cover is provided on the outer side of the two side panels. Each side panel has multiple card slots, and the cover is fixedly provided with card posts that engage with the card slots.
[0006] Furthermore, each card interface includes a vertical card slot, and the top side of the vertical card slot has a notch for the card post to pass through.
[0007] Furthermore, both the upper and lower sides of the side panel are sealed by connecting plates, and the height of the square area formed by the side panel and the connecting plate is less than the height of the opening of the lid.
[0008] Furthermore, a locking strip is fixedly installed on the cabinet body, and a bent plate that engages with the locking strip is fixedly installed on the box cover. When the locking post is inserted into the bottom of the vertical locking groove, the bottom of the bent plate is inserted into the inside of the locking strip.
[0009] Furthermore, a pull-out plate is fixedly installed on the top of the lid.
[0010] The beneficial effects of this utility model are as follows: The explosion-proof cover of the switch cabinet can be snapped into the cabinet body, which can achieve a better fixing effect and prevent the cover from being blown away by an explosion. Moreover, the snap-fit method of vertical slot and pull-out pin makes disassembly and installation simple and quick, without spending much time. After snapping, it has a strong effect against the impact of side explosions. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0020] Reference Figures 1 to 5 The explosion-proof switchgear shown includes a cabinet body 1 and a cover 2 mounted on the cabinet body 1. The cabinet body 1 has two side panels 1a, and the cover 2 covers the outside of the two 1a panels. Each side panel 1a has multiple snap-fit interfaces, and the cover 2 is fixedly provided with snap-fit posts 2a that engage with the snap-fit interfaces. This snap-fit connection between the cover 2 and the cabinet body 1 provides a better securing effect.
[0021] Each card slot includes a vertical card groove 1a1, and a notch 1a2 is provided on the top side of the vertical card groove 1a1 for the card post 2a to pass through. The card post 2a passes through the notch 1a2 and then slides down along the vertical card groove 1a1, thereby achieving the snap-fit fixation of the cover 2. This snap-fit method is relatively simple and quick to disassemble and install, does not require much time, and after snap-fit, it has a strong effect against the side explosion impact.
[0022] Both the upper and lower sides of the side panel 1a are sealed by connecting plates. The height of the square area formed by the side panel 1a and the connecting plates is less than the height of the opening of the lid 2. This allows the lid 2 to be installed by first covering the outer edge of the square area. At this time, the locking post 2a will slide through the notch 1a2 into the vertical locking groove 1a1. Then, by pushing the lid 2 upward, the locking post 2a can be locked into the bottom of the inner edge of the vertical locking groove 1a1, thus forming a direct locking and fixing between the lid 2 and the cabinet 1.
[0023] A retaining strip 3 is fixedly installed on the cabinet body 1, and a bent plate 4 that engages with the retaining strip 3 is fixedly installed on the lid 2. When the retaining post 2a is inserted into the bottom of the vertical retaining groove 1a1, the bottom of the bent plate 4 is inserted into the inside of the retaining strip 3. By adding the retaining strip 3 and the bent plate 4, the fixing effect is further enhanced.
[0024] A lifting plate 5 is fixedly installed on the top of the lid 2. By providing the lifting plate 5, the lid 2 can be pulled up more easily when it is removed.
[0025] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
