Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet installation structure that facilitates internal wiring. Background Technology
[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are suitable for situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used for situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.
[0003] Utility model patent CN221282591U discloses a power distribution cabinet installation structure that facilitates internal wiring. The structure includes a cabinet body, an internally connected mounting plate, a first fixed plate fixedly mounted at the bottom of the mounting plate, and a second fixed plate fixedly mounted at the top of the mounting plate. Slider blocks are fixedly mounted on both the upper and lower sides of the mounting plate. The advantages are: by setting up the first fixed plate, second fixed plate, slider, bracket, and support rod, on the one hand, when the slider slides inside the groove, the mounting plate can only slide linearly; when the slider is inside the first rotating groove, the mounting plate can rotate freely, thus facilitating the installation of electrical components and the organization of wiring harnesses. On the other hand, when the bracket slides away from the cabinet door, the inclined groove causes the support rod to drive the bracket upwards. Simultaneously, the soft pads used allow the bracket to slide upwards while pressing down on the wires.
[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: Although the above-mentioned device can realize the forward movement and rotation of the mounting plate, after the equipment is installed and the wires are passed through the through slot, there is no separation structure between the wires, which makes the wires easy to get tangled together. In addition, the device can only fix the wires after the mounting plate is reset to the rear. During the movement of the mounting plate, the wires are easy to disperse, resulting in poor subsequent fixing effect and difficulty in meeting the use requirements. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a power distribution cabinet installation structure that facilitates internal wiring, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a power distribution cabinet installation structure that facilitates internal wiring, including a cabinet body and an equipment mounting plate. The cabinet body has a cabinet door hinged to the front side, and side doors are installed on both the left and right sides of the cabinet body via hinges. The bottom wall inside the cabinet body has two linear slide rails extending forward and backward, and sliders are slidably connected to the surface of the linear slide rails. The top of the sliders is fixedly connected to the bottom of the equipment mounting plate. The front side of the equipment mounting plate has multiple mounting rails extending left and right, and the back of the equipment mounting plate has multiple wiring mechanisms. The surface of the equipment mounting plate has multiple wire-passing grooves that cooperate with the wiring mechanisms.
[0007] Furthermore, the wire separating mechanism includes an I-shaped plate located above the wire threading groove. The surface of the I-shaped plate is fixedly connected to the surface of the equipment mounting plate. Several sliding shells are slidably connected to the surface of the I-shaped plate. A wire threading frame is fixed to the bottom of each sliding shell. An extension block is fixed to the surface of the sliding shell. A spring is fixed to the bottom of the extension block. A pressure plate is fixed to the bottom of the spring. The pressure plate is slidably connected to the inner wall of the wire threading frame.
[0008] Furthermore, a connecting frame is detachably connected to the bottom of the threading frame, a winding roller is installed on the surface of the connecting frame, an extension plate is fixed on the surface of the connecting frame, and a positioning mechanism is installed on the surface of the extension plate.
[0009] Furthermore, the positioning mechanism includes a lead screw, which is threaded through an extension plate. The top of the lead screw is rotatably connected to an arc-shaped clamping plate that cooperates with a winding roller. Two guide rods slide through the surface of the extension plate, and the tops of the guide rods are fixedly connected to the bottom of the arc-shaped clamping plate.
[0010] Furthermore, the surface of the arc-shaped clamp is provided with multiple cable outlet grooves.
[0011] Furthermore, guide plates are fixed on both the left and right sides of the inner wall of the wire threading frame, and the pressure plate is slidably connected to the surface of the guide plate.
[0012] Furthermore, a T-shaped plate is fixed to the bottom of the threading frame, and a T-shaped groove is formed on the surface of the connecting frame to cooperate with the T-shaped plate.
[0013] Furthermore, two positioning frames extending forward and backward are fixed to the bottom wall inside the cabinet, and two first positioning blocks are fixed below the surface of the equipment mounting plate. Positioning holes are opened on the surface of the first positioning blocks and the positioning frames. The number of positioning holes on the surface of the positioning frame is two, and they are distributed at intervals.
[0014] Furthermore, the cabinet has an open structure on both the left and right sides, and hinges are fixed on both the left and right sides of the cabinet surface. Side doors are fixed on the hinge surfaces. A third positioning block is fixed above the left and right sides of the cabinet surface, and a second positioning block is fixed above the side door surface. Both the third and second positioning blocks have through holes on their surfaces.
[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0016] First, the sliding design of the equipment mounting plate and the opening design of the side door allow staff to complete equipment installation and wiring without entering the cabinet, greatly reducing the difficulty of operation. The elastic clamping and winding roller storage function of the cable distribution mechanism ensures that the cable remains fixed during the movement of the equipment mounting plate, avoiding the problem of cable dispersion after resetting in traditional technology. The open cabinet and multi-directional operation entrances of the side door, combined with the locking mechanism of multiple positioning blocks, significantly improve maintenance efficiency and safety.

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0024] Please see Figure 1-4 An installation structure for a power distribution cabinet that facilitates internal wiring includes a cabinet body 1 and an equipment mounting plate 2. The cabinet body 1 has a cabinet door 6 hinged to its front side, and side doors 8 are installed on both the left and right sides of the cabinet body 1 via hinges 7. The bottom wall inside the cabinet body 1 has two linear slide rails 9 extending forward and backward, and sliders 10 are slidably connected to the surface of the linear slide rails 9. The top of the sliders 10 is fixedly connected to the bottom of the equipment mounting plate 2. The front side of the equipment mounting plate 2 has multiple mounting rails 3 extending left and right, and the back of the equipment mounting plate 2 has multiple cable distribution mechanisms 5. The surface of the equipment mounting plate 2 has multiple cable passages 4 that cooperate with the cable distribution mechanisms 5.
[0025] Through the above technical solution, the equipment mounting plate 2 is slidably connected to the linear slide rail 9 via the bottom slider 10, realizing the forward and backward movement of the equipment mounting plate 2. Multiple mounting rails 3 are set on the surface of the equipment mounting plate 2 for fixing electrical equipment. The cable tray 4 provides a centralized passage for cables. The cable separation mechanism 5 can separate the lines individually to avoid them getting tangled together, and realize the fixing of the lines and the winding of redundant cables, ensuring that the cables remain stable in the cable tray 4. The open design on both sides of the cabinet 1 and the side door 8 connected by the hinge 7 provide multi-angle operating space, allowing the cables to be operated from multiple directions and reducing maintenance blind spots.
[0026] The wire separating mechanism 5 includes an I-shaped plate 501, which is located above the wire threading groove 4. The surface of the I-shaped plate 501 is fixedly connected to the surface of the equipment mounting plate 2. Several sliding shells 502 are slidably connected to the surface of the I-shaped plate 501. A wire threading frame 503 is fixed to the bottom of the sliding shell 502. An extension block is fixed to the surface of the sliding shell 502. A spring 504 is fixed to the bottom of the extension block. A pressure plate 505 is fixed to the bottom of the spring 504. The pressure plate 505 is slidably connected to the inner wall of the wire threading frame 503. A connecting frame 506 is detachably connected to the bottom of the wire threading frame 503. A winding roller 507 is installed on the surface of the connecting frame 506. An extension plate 508 is fixed to the surface of the connecting frame 506. A positioning mechanism is installed on the surface of the extension plate 508.
[0027] Through the above technical solution, the sliding shell 502 can slide laterally along the I-beam plate 501, and different numbers of sliding shells 502 can be installed on the surface of the I-beam plate 501 as needed. The wire threading frame 503 is connected to the spring 504 and the pressure plate 505 through the extension block. The spring 504 provides downward pressure so that the pressure plate 505 and the inner wall of the wire threading frame 503 form an adaptive clamping space. After the cable is threaded in, it is fixed by the elastic force. The detachable connection between the connecting frame 506 and the wire threading frame 503 allows the wire threading frame 503 to be installed on the surface of the connecting frame 506 when it is necessary to wind a long cable. Conversely, it can separate the wire threading frame 503 from the connecting frame 506. The winding roller 507 is used to store redundant cables, and the positioning mechanism can fix the wound cable to prevent it from loosening.
[0028] The surface positioning mechanism of the extension plate 508 includes a lead screw 509, which is threaded through the extension plate 508. An arc-shaped clamping plate 510 is rotatably connected to the top of the lead screw 509. Two guide rods 511 slide through the surface of the extension plate 508, and the top of the guide rods 511 is fixedly connected to the bottom of the arc-shaped clamping plate 510.
[0029] With the above technical solution, when the lead screw 509 is rotated, the arc-shaped clamp 510 at its top moves vertically along the guide rod 511, so that the arc-shaped clamp 510 can press the wound cable tightly to prevent the cable from loosening. The guide rod 511 is slidably connected to the extension plate 508 to ensure the stability of the clamp's movement trajectory.
[0030] The surface of the arc-shaped clamp 510 is provided with multiple cable outlet grooves 512. Guide plates 514 are fixed on both the left and right sides of the inner wall of the cable pass frame 503. The pressure plate 505 is slidably connected to the surface of the guide plate 514.
[0031] Through the above technical solution, the cable outlet 512 provides a directional outlet for the cable, avoids cross-interference of multiple cables, and adapts to complex wiring requirements. The guide plate 514 provides a straight guide for the pressure plate 505, ensuring that the pressure plate 505 can move vertically along a straight line.
[0032] The bottom of the wire guide frame 503 is fixed with a T-shaped plate 513, and the surface of the connecting frame 506 is provided with a T-shaped groove for use with the T-shaped plate 513.
[0033] Through the above technical solution, the T-shaped plate 513 at the bottom of the wire guide frame 503 is inserted into the T-shaped groove of the connecting frame 506, and the two can be quickly connected or separated by pushing and pulling operations. This modular design improves the convenience of maintenance.
[0034] The cabinet 1 has two positioning frames 11 that extend forward and backward on its inner bottom wall. The equipment mounting plate 2 has two first positioning blocks 12 that are fixed below its surface. The first positioning blocks 12 and the positioning frames 11 are both provided with positioning holes 13. The number of positioning holes 13 on the surface of the positioning frame 11 is two, and they are distributed at intervals.
[0035] With the above technical solution, after the two are aligned through the positioning hole 13, bolts or pins are inserted to fix the equipment mounting plate 2, so as to avoid the equipment mounting plate 2 from moving during and after the equipment installation.
[0036] A third positioning block 15 is fixed on the upper part of both the left and right sides of the cabinet body 1, and a second positioning block 14 is fixed on the upper part of the side door body 8. Both the third positioning block 15 and the second positioning block 14 have through holes.
[0037] With the above technical solution, when the side door 8 is closed, the holes on the upper and lower sides are aligned. At this time, a locking device can be inserted through the holes to achieve a stable closure of the side door 8.
[0038] Working principle: First, the operator pulls the equipment mounting plate 2, and the slider 10 slides outward along the linear slide rail 9, moving the equipment mounting plate 2 to the front of the cabinet 1; this facilitates the installation of electrical equipment from the front. Then, the side doors 8 are opened, allowing the operator to operate on the back of the equipment mounting plate 2. After the equipment is installed on the surface of the mounting rail 3, the cable is introduced into the cabinet 1 through the cable guide 4. The sliding shell 502 of the cable distribution mechanism 5 is adjusted laterally according to the position of the equipment. The cable guide frame 503 elastically clamps the cable through the pressure plate 505, and the winding roller 507 collects the redundant cable, completing the cable arrangement operation. Afterward, the equipment mounting plate 2 is reset. During the reset process, the spring 504 of the cable distribution mechanism 5 continuously presses the cable to prevent it from moving and becoming loose. The arc-shaped clamp 510 presses down on the cable through the lead screw 509 to ensure the cable is in a stable position.
