Description

Technical Field

[0001] This utility model relates to a switch cabinet, specifically, to a switch cabinet that is easy to wire and maintain. Background Technology

[0002] Switchgear is a key device in power systems used for distributing, controlling, and protecting electrical equipment. It requires a large number of cables to be laid inside to connect various electrical components, such as circuit breakers and transformers. In the current technology, the wiring is often carried out by setting a movable mounting base inside the switchgear and installing wire clamps on the base. The advantage of this wiring method is that the movable base can centrally manage related cables, which facilitates the subsequent inspection and maintenance of cables.

[0003] However, this technology has the following drawbacks: First, the cable clamps rely solely on their own elastic clamping force to fix the cables. This passive clamping method lacks stability. When the cables are pulled externally or the cabinet is vibrated, the cables are prone to coming loose from the opening side of the clamps, posing a safety hazard. Second, the mounting base itself lacks rigid positioning on the guide rail. It is prone to accidental sliding or displacement during wiring or daily operation. This not only disrupts the overall order of the wiring but also subjectes the cables and their connections to additional mechanical stress, leading to loose connections or even damage. Utility Model Content

[0004] The purpose of this invention is to provide a switch cabinet that facilitates wiring and maintenance, so as to solve the problems mentioned in the background art.

[0005] To address the above problems, the present invention aims to provide a switch cabinet that facilitates wiring and maintenance. The cabinet includes a cabinet body with several vertically arranged movable positioning components inside. Each movable positioning component includes a guide rail fixedly installed on the inner wall of the cabinet. Several cable fixing mechanisms are arranged on the guide rail, each cable fixing mechanism including a slider slidably mounted on the guide rail. Several wire clamps are horizontally arranged and fixedly installed on the side of the slider away from the guide rail. A cover plate is hinged to one side of the slider, and a locking mechanism is provided at the other end of the cover plate. A limit mechanism is also provided on the slider. When the cover plate rotates to a position spanning all the wire clamps, the limit mechanism locks the cover plate onto the slider, and simultaneously, the locking mechanism locks the slider onto the guide rail.

[0006] As a further improvement to this technical solution, the wire clamp has a U-shaped structure, with an opening on the side of the wire clamp away from the slider. When the cover plate rotates to a position spanning all the wire clamps, the cover plate blocks the opening of the wire clamp.

[0007] As a further improvement to this technical solution, the limiting mechanism includes a bolt threaded onto the cover plate, and a nut is fixedly installed on the slider, with the nut located between two adjacent clamps.

[0008] As a further improvement to this technical solution, when the cover plate is rotated to a position spanning all the clamps, the bolt and nut are threaded together.

[0009] As a further improvement to this technical solution, a blocking component is provided on the side of the cover plate near the slider, corresponding to each wire clamp. The blocking component includes two blocks fixedly installed on the cover plate.

[0010] As a further improvement to this technical solution, when the cover plate is rotated to a position spanning all the wire clamps, the two stops are respectively located at the two ends of the corresponding wire clamps.

[0011] As a further improvement to this technical solution, the locking mechanism includes a round rod integrally formed on the cover plate, and the guide rail has several arc-shaped grooves arranged in a horizontal array on the side near the slider.

[0012] As a further improvement to this technical solution, when the cover plate is rotated to a position spanning all the wire clamps, the round rod is embedded in a corresponding arc-shaped groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This switch cabinet, which facilitates wiring maintenance, allows the cover plate to rotate across all clamps after the cable is inserted into the elastic clamp. Then, the bolt in the limiting mechanism is screwed into the nut on the slider, locking the cover plate onto the slider and sealing the clamp opening. Simultaneously, the stop on the cover plate contacts both ends of the clamp, limiting its elastic deformation and preventing the cable from slipping out of the clamp when pulled or vibrated. At the same time, the round rod in the locking mechanism embeds into the arc groove on the guide rail, locking the slider onto the guide rail and preventing accidental sliding or displacement. This synchronous fixing mechanism ensures the cable is securely clamped and the slider position is reliable, solving the problems of easy cable loosening and unstable mounting base, thus improving the safety and orderliness of wiring maintenance.

[0016] 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. Example 1

[0017] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a switch cabinet that facilitates wiring maintenance, including a cabinet body 1. Several moving positioning components 2 are arranged vertically inside the cabinet body 1. The moving positioning components 2 include a guide rail 21 fixedly installed on the inner wall of the cabinet body 1. Several cable fixing mechanisms 22 are arranged on the guide rail 21. The cable fixing mechanisms 22 are used to position and fix the cables.

[0018] The cable fixing mechanism 22 includes a slider 221 slidably mounted on the guide rail 21. Several wire clips 222 made of elastic plastic are horizontally arrayed and fixed on the side of the slider 221 away from the guide rail 21. The wire clips 222 have a U-shaped structure and are open on the side away from the slider 221. Since the wire clips 222 are made of elastic plastic, their U-shaped structure can undergo elastic deformation when subjected to force, thereby generating a continuous clamping force to firmly restrict the cable inside the wire clips 222, thus achieving the clamping and fixing of the cable.

[0019] In actual use, the operator can insert the cable into the wire clamp 222 through the opening and use the elastic clamping force of the wire clamp 222 itself to pre-fix the cable.

[0020] To further enhance the fixing effect, a cover plate 223 is hinged to one side of the slider 221, and a locking mechanism is provided at the other end of the cover plate 223. A limit mechanism is also provided on the slider 221. When the cover plate 223 rotates to the position that spans all the wire clamps 222, the limit mechanism locks the cover plate 223 onto the slider 221. At this time, the cover plate 223 acts as a physical barrier, directly blocking the openings of all the wire clamps 222, fundamentally preventing the cable from coming out of the opening side due to any accidental force. At the same time, the locking mechanism locks the slider 221 onto the guide rail 21, thereby achieving overall fixing of the cable inside the cabinet 1.

[0021] The following details the structure of the limit mechanism, referring to... Figures 4-6 The limiting mechanism includes a bolt 225 threaded onto the cover plate 223, and a nut 226 fixedly installed on the slider 221. The nut 226 is located between two adjacent wire clamps 222. A blocking component is provided on the side of the cover plate 223 near the slider 221, corresponding to each wire clamp 222. The blocking component includes two blocks 227 fixedly installed on the cover plate 223. The blocks 227 are triangular prisms. The side of the two blocks 227 that are close to each other is an inclined surface, so that the two blocks form a figure-eight structure, which makes it easy for the two ends of the wire clamp 222 to be engaged.

[0022] Reference Figure 6 In the initial state, the cover plate 223 is in the open state, and the opening of the wire clamp 222 is completely open. After the operator inserts the cable into the wire clamp 222, the cover plate 223 is rotated to a position that spans all the wire clamps 222. At this time, the positions of the bolt 225 and the nut 226 are corresponding. The operator rotates the bolt 225 and screws it into the nut 226. The bolt 225 and the nut 226 are threaded together. At this time, the bolt 225 and the nut 226 cooperate to prevent the cover plate 223 from rotating back to its original position, thereby fixing the position of the cover plate 223.

[0023] When the cover plate 223 is locked in this position, the two blocks 227 approach each other on one side and contact the two ends of the corresponding clamps 222 respectively. At the same time, the inclined surfaces of the two blocks 227 guide the two ends of the clamps 222 towards each other, so that the clamps 222 clamp and fix the cable. If the cable is subjected to outward pulling force or vibration impact, it will force the opening ends of the elastic clamps 222 to open outward to release the cable. The blocks 227 play a blocking role here, limiting the elastic deformation range of the two ends of the clamps 222, so that they cannot open to a degree sufficient to release the cable. Through this physical interference, the clamping force of the clamps 222 on the cable can be maintained under the force state, thereby preventing the cable from coming out of the inside of the clamps 222, thus further strengthening the overall sealing function of the cover plate 223, and together with the cover plate 223, they constitute a dual anti-dislodgement mechanism.

[0024] The structure of the locking mechanism is described in detail below. The locking mechanism includes a round rod 224 integrally formed on the cover plate 223. Several arc-shaped grooves 211 are arranged in a horizontal array on the side of the guide rail 21 near the slider 221. When the cover plate 223 rotates to a position that spans all the wire clamps 222, the round rod 224 is embedded in the corresponding arc-shaped groove 211. While the limiting mechanism fixes the position of the cover plate 223, the engagement of the round rod 224 with the arc-shaped groove 211 restricts the sliding of the slider 221 along the guide rail 21.

[0025] When using this device, the cable is inserted into the opening of the clamp 222. The U-shaped clamp 222, made of elastic plastic, provides initial pre-fixation of the cable using its own elastic clamping force. Then, the cover plate 223 is rotated to span all the clamps 222 to block their openings. The position of the cover plate 223 is locked onto the slider 221 by a limiting mechanism. While the cover plate 223 is locked, the round rod 224 on it is embedded into the arc groove 211 of the guide rail 21. The slider 221 is locked onto the guide rail 21 by this locking mechanism, thereby achieving reliable overall fixation of the cable inside the cabinet 1.

[0026] When it is necessary to open the cover plate 223 to add, remove, or maintain cables, the operator only needs to unscrew the bolt 225 from the inside of the nut 226 to release the locking mechanism from the cover plate 223, thus easily opening the cover plate 223. During this process, as the cover plate 223 rotates, the round rod 224 will simultaneously disengage from the arc groove 211, thereby releasing the locking mechanism from the slider 221, allowing the slider 221 to slide freely along the guide rail 21. The advantage of this synchronous release design is that the operator can automatically unlock the slider 221 while opening the cover plate 223, adjusting the cable position or adding or removing cables for maintenance without additional steps, improving the convenience and efficiency of wiring maintenance, reducing operation time, and lowering the risk of misoperation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
