Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical cabinet technology, specifically to a robust subway electrical cabinet. Background Technology
[0002] Subway electrical cabinets are electrical control and distribution devices in subway systems. They are used to manage and distribute power and control various equipment, such as signaling systems, lighting, ventilation equipment, and other electrical systems. Electrical cabinets may include components such as circuit breakers, relays, and control panels to ensure the stability and safety of the power system.
[0003] A utility model patent with Chinese authorized patent publication number "CN220086704U" discloses "a robust subway electrical cabinet, comprising an electrical cabinet body, a fixed base installed below the electrical cabinet body, fixed brackets fixedly installed on both sides of the fixed base, lower clamping plates installed inside both sides of the fixed base, and a threaded rod rotatably installed at the upper end of each lower clamping plate, with each threaded rod threaded through and installed on the inner wall of the fixed base." It utilizes a spring to move upwards and reset, where the inclined plate acts as a barrier against the sides of the electrical cabinet body. Simultaneously, the rubber pads on the inner wall of the fixed base provide good filling, reducing the probability of the electrical cabinet body swaying inside the fixed base. By employing auxiliary secondary fixing, the stability of the electrical cabinet body inside the fixed base is further improved, thus enhancing the robustness of the electrical cabinet body.
[0004] In the above-mentioned utility model, the electrical cabinet is fixed multiple times by components such as inclined plates, clamps and rubber pads, thereby improving its installation firmness. However, this also makes it more cumbersome to use and affects its actual disassembly and assembly efficiency. At the same time, it mainly fixes the bottom of the electrical cabinet. Since the electrical cabinet is mainly used in the subway system, and there may be many circuit system devices in the subway, the electrical cabinet may also be larger. Therefore, fixing only the bottom may not be able to guarantee its overall firmness and stability.
[0005] In view of this, we propose a robust subway electrical cabinet. Utility Model Content
[0006] Technical problems to be solved
[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a subway electrical cabinet with strong sturdiness, which can effectively solve the problem that the existing technology is cumbersome to fix the electrical cabinet and only fixes it to the bottom, which cannot guarantee the overall sturdiness and stability.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] The present invention will be further described below with reference to the embodiments.
[0028] Example: A robust subway electrical cabinet includes a fixed frame 1 and an electrical cabinet body 2 disposed inside the fixed frame 1. The top and bottom of the inner cavity of the fixed frame 1 are provided with second sliding grooves 11. Two sets of sliding strips 12 are slidably installed on the inner side walls of the two sets of second sliding grooves 11. On the side of the two sets of sliding strips 12 slidably installed on the inner side walls of the two sets of second sliding grooves 11 away from the second sliding grooves 11, L-shaped clamping plates 3 are fixedly installed. A driving member is provided on one side of the four sets of L-shaped clamping plates 3, and the driving member is disposed inside the fixed frame 1. The driving member can simultaneously drive the four sets of L-shaped clamping plates 3 to move, thereby clamping and fixing the electrical cabinet body 2.
[0029] Specifically, the fixed frame 1 can be used to fix the entire unit in the corresponding position in the subway system. At the same time, the fixed frame 1 has many hollow designs to facilitate the wiring of the electrical cabinet body 2. When the electrical cabinet body 2 needs to be installed, the electrical cabinet body 2 can be sent into the corresponding position of the fixed frame 1. The four sets of L-shaped clamps 3 support and limit the electrical cabinet body 2. At this time, the driving component can drive the L-shaped clamps 3 set on the top and bottom to move towards the electrical cabinet body 2, thereby clamping the four corners of the electrical cabinet body 2 to ensure its firmness. At the same time, the second sliding groove 11 and the internal sliding strip 12 can effectively improve the stability of the L-shaped clamps 3 during the movement.
[0030] Specifically, the driving component includes a bidirectional lead screw 5 rotatably mounted at the bottom of the inner cavity of the fixed frame 1. The surface of the bidirectional lead screw 5 is threaded with two sets of threaded sleeves 6. Guide plates 7 are fixedly mounted on the side of the two sets of threaded sleeves 6 near the electrical cabinet body 2. The two sets of guide plates 7 are U-shaped. The surface of the two sets of guide plates 7 is provided with two sets of guide grooves 9. Guide rods 10 are slidably mounted on the inner cavity sidewall of the two sets of guide grooves 9. The ends of the four sets of guide rods 10 near the electrical cabinet body 2 are fixedly mounted on one side of the L-shaped clamping plate 3. The four sets of L-shaped clamping plates 3 can simultaneously clamp and fix the four corners of the electrical cabinet body 2. Two sets of first sliding grooves 8 are provided on one side of the fixed frame 1. The inner cavity sidewall of the two sets of first sliding grooves 8 is slidably connected to the surface of the two sets of guide plates 7. The top of the bidirectional lead screw 5 rotates through the fixed frame 1, and a knob 4 is fixedly mounted on the top of the bidirectional lead screw 5.
[0031] Specifically, when it is necessary to install and fix the electrical cabinet body 2, the knob 4 can be turned to drive the bidirectional lead screw 5, which is rotatably installed at the bottom of the inner cavity of the fixing frame 1, to rotate. The surface of the bidirectional lead screw 5 has two sets of opposite thread patterns. Since the two sets of guide plates 7 are slidably installed in the first slide groove 8 and are limited by the first slide groove 8, the two sets of guide plates 7 can be driven to move towards the middle while the bidirectional lead screw 5 is rotating. Furthermore, the guide grooves 9 opened on the guide plates 7 guide the guide rod 10. When the L-shaped clamps 3 are brought together by the guide rod 10, they can be clamped and fixed at all four corners of the electrical cabinet body 2. Elastic rubber pads are fixedly installed on the inner side walls of the multiple sets of L-shaped clamps 3, which not only improves the firmness of the clamping and installation of the electrical cabinet body 2, but also avoids wear on the surface of the electrical cabinet body 2 due to excessive clamping force. Conversely, when it is necessary to remove the electrical cabinet body 2, simply turn the knob 4 in the opposite direction to move the multiple sets of L-shaped clamps 3 outward and release the electrical cabinet body 2.
[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
