Transformer cabinet with self-locking anti-falling cable fixing clamp

Abstract

This utility model belongs to the field of power equipment, and in particular to a transformer cabinet with a self-locking anti-drop cable clamp. It addresses the problem that existing cabinets have limited internal space, requiring operation in a confined area during installation or maintenance; and that existing fixing methods, often relying on cable ties or simple clips, are prone to loosening and falling off under equipment vibration or external force. The proposed solution includes a cabinet with an open top and an operating hole in the upper half of the back. A back plate is slidably connected to the inner walls of both sides of the operating hole, and a top plate is fixedly connected to the top of the back plate. A cabinet door is hinged to one side of the cabinet. Wiring holes are located at the bottom of the back plate and the top of the back of the cabinet. In this utility model, through the linkage design of the upper pressure plate and the clamping plate, when a cable is inserted into the wiring hole, the arc-shaped hole of the upper pressure plate automatically squeezes the clamping plate, causing it to clamp the cable under the action of a second spring. The top plate and back plate can be moved upwards as a whole, and temporary support is provided by the clearance groove of the sliding support plate to prevent the structure from falling during operation.

Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a transformer cabinet with a self-locking anti-drop cable fixing clamp. Background Technology

[0002] In the field of power equipment, transformer cabinets, as key power distribution devices, rely heavily on the installation of internal electrical components and the securing of cables to ensure stable equipment operation. Traditional transformer cabinets face the following technical bottlenecks in practical use:

[0003] The cabinet's interior space is compact, requiring operation in a small area during installation or maintenance, which can easily lead to cable tangling, accidental contact with electrical components, or even safety hazards.

[0004] Existing fixing methods mostly rely on cable ties or simple clips, which are prone to loosening and falling off under equipment vibration or external force, affecting the stability of power supply.

[0005] To address the aforementioned issues, this application proposes a transformer cabinet that integrates a self-locking anti-drop cable clamp with a structural linkage design. Through the combination of mechanical linkage and elastic clamping technology, safe and efficient cable routing and fixing are achieved. Utility Model Content

[0006] The purpose of this utility model is to solve the problems of existing technologies, such as the compact internal space of the cabinet, which requires operation in a small area during installation or maintenance, easily leading to cable entanglement, accidental contact with electrical components, and even safety hazards; and the shortcomings of existing fixing methods, which mostly rely on cable ties or simple buckles, which are easy to loosen and fall off under equipment vibration or external force, affecting the stability of power supply. Therefore, this utility model proposes a transformer cabinet with a self-locking anti-fall-off cable fixing clamp.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A transformer cabinet with a self-locking anti-drop cable clamp includes a cabinet body, which has an opening at the top and an operating hole in the upper half of the back. The inner walls on both sides of the operating hole are slidably connected to a back plate, and the top of the back plate is fixedly connected to a top plate.

[0009] The cabinet door is hinged to one side of the cabinet body;

[0010] Wiring holes are located at the bottom of the back panel and the top of the back of the cabinet.

[0011] A fixing plate is fixed to the inner wall of one side of the cabinet and located directly below the wiring hole, with a fixing component on its top;

[0012] A limiting component is located on the side of the cabinet near the cabinet door to lock the top panel;

[0013] When the cabinet door is opened, the limiting component is triggered to release the top plate lock, and the back plate can move upward along the operating hole to expose the wiring area; when the back plate moves downward, its bottom is inserted into the clearance groove of the sliding support plate on the inner wall of the cabinet to form temporary support, and at the same time the back plate drive fixing component clamps the cable.

[0014] In one possible design, the fixing component includes:

[0015] The chute is located at the top of the fixed plate;

[0016] Two sliders are symmetrically connected within the groove;

[0017] The second spring has its two ends connected to the opposite sides of the two sliders via spring seats;

[0018] The clamping plate, vertically fixed to the top of the slider, is used to clamp the cable.

[0019] In one possible design, the limiting component includes:

[0020] Sealing plate, fixed to the inner wall of the cabinet;

[0021] A rectangular block is fixed to the top of the sealing plate and has a T-shaped hole.

[0022] T-block, slidably connected inside T-hole;

[0023] The first spring is located between the inner walls of the T-block and the rectangular block;

[0024] Fixing block, fixed to the inside of the cabinet door;

[0025] When the cabinet door is closed, the fixing block pushes the T-shaped block to compress the first spring and insert it into the socket of the top plate to lock the top plate.

[0026] In one possible design, a strip plate is fixed to the bottom of the top plate, and side blocks are vertically connected to both ends of the strip plate. The side blocks have insertion holes that mate with T-shaped blocks.

[0027] In one possible design, multiple upper pressure plates are fixed to the side of the back panel facing the cabinet door, and an arc-shaped hole is opened at the bottom of the upper pressure plate; when the back panel moves down, the inclined surface of the arc-shaped hole presses against the outside of the clamping plate, forcing the two clamping plates to move towards each other to clamp the cable.

[0028] In one possible design, sliding support plates are slidably connected to the inner walls on both sides of the cabinet. A clearance groove is opened at the top of the sliding support plate, and a temporary support structure is formed when the bottom of the back panel is inserted into the clearance groove.

[0029] In one possible design, a rubber anti-slip pad is attached to the inner side of the clamping plate, and the maximum distance between the two clamping plates is less than the cable diameter.

[0030] In one possible design, ventilation holes are provided on both sides of the cabinet, and a handle is fixedly connected to one side of the cabinet door.

[0031] In this application, when installing internal electrical components, the cabinet door needs to be opened by the handle. At this time, the fixing block on one side of the cabinet door will not push the T-block. The T-block moves laterally under the elastic force of the first spring and moves out of the socket, thereby releasing the braking state of the side block.

[0032] At this point, the top and back panels can be moved upwards as a whole to make room for the cabling. Then, the sliding support plates on both sides can be moved laterally, and the bottom of the back panel can be inserted into the recessed slot to ensure that the top and back panels will not fall off suddenly during installation, thus ensuring safety.

[0033] At this point, the cable can be laid out normally. The cable is then connected inside the wiring hole below. After the cable laying is completed, the sliding support plate is reset, and the top plate and back plate move down normally. At this time, multiple upper pressure plates on one side of the back plate press the two clamping plates together. The two clamping plates drive the slider to slide inside the slide groove and move closer to each other. The clamping plates fix the cable to prevent it from falling. After closing the cabinet door, the T-block is inserted into the socket again to ensure the stability of the device.

[0034] Beneficial effects: Through the linkage design of the upper pressure plate and the clamping plate, when the cable is inserted into the wiring hole, the arc-shaped hole of the upper pressure plate automatically squeezes the clamping plate, causing it to clamp the cable under the action of the second spring. This structure can achieve self-adaptive fixation without manual operation, effectively preventing the cable from falling off, and is especially suitable for vibration environments or frequent maintenance scenarios.

[0035] The top and back plates can be moved upwards as a whole, with temporary support provided by the clearance groove of the sliding support plate to prevent the structure from falling during operation. This design fully exposes the wiring area, facilitating wiring, maintenance, and component installation, significantly improving operational efficiency and safety.

[0036] When the cabinet door is opened, the fixing block releases its pressure on the T-block, and the T-block retracts from the socket under the action of the first spring, releasing the braking state of the top plate. After the cabinet door is closed, the T-block automatically inserts into the socket, locking the top plate. This linkage mechanism ensures structural stability during operation and prevents structural displacement or overturning caused by misoperation.

[0037] Both the fixing components (clamping plate, spring) and the limiting components (T-block, insertion hole) adopt a modular design, which facilitates quick replacement or maintenance; the clearance groove of the sliding support plate is inserted into the bottom of the back plate to form double support, further reducing operational risks.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0045] In one embodiment; reference Figure 1-5 A transformer cabinet with a self-locking anti-drop cable clamp.

[0046] The top of cabinet 1 remains open. An operating hole 25 is provided on the upper half of the back of cabinet 1. Sliding rails are installed on the inner walls of both sides of the operating hole 25, and the back panel 6 is slidably connected to the operating hole 25 via the rails. The top plate 5 is fixed to the top of the back panel 6 with bolts. The cabinet door 4 is connected to the right side of cabinet 1 via a hinge. Circular wiring holes 7 are provided at the bottom of the back panel 6, corresponding to the top of the back of cabinet 1; the number is determined according to cable requirements. Multiple horizontal fixing plates 12 are welded to the inner wall of the left side of cabinet 1. The number of fixing plates 12 is the same as the number of wiring holes 7, and they are vertically positioned directly below the wiring holes 7.

[0047] A fixing component is provided on the top of the fixing plate 12: a straight groove 23 is milled into the top surface of the fixing plate 12, and two symmetrical aluminum alloy sliders 21 are installed in the groove 23. The bottom of the sliders 21 is embedded in the groove of the groove 23 to achieve a sliding fit. A second spring 22 is installed between the two sliders 21, and the two ends of the second spring 22 are pressed against the inner side of the slider 21 by welded spring seats. A clamping plate 20 is vertically fixed to the top of each slider 21, and a rubber anti-slip pad is attached to the inner side of the clamping plate 20 for clamping the cable.

[0048] A limiting component is installed on the side of cabinet 1 near cabinet door 4: an L-shaped sealing plate 26 is welded to the inner left wall of cabinet 1, and a rectangular block 19 is fixed to the upper surface of the sealing plate 26. A T-shaped hole 16 is opened on the right side of the rectangular block 19, and a T-shaped block 17 that can slide laterally is installed in the T-shaped hole 16. A first spring 18 is installed between the left side of the T-shaped block 17 and the inner wall of the T-shaped hole 16. A cylindrical fixing block 9 is welded to the inner side of cabinet door 4, and the axis of the fixing block 9 is aligned with the center of the T-shaped block 17.

[0049] A strip plate 13 is welded to the front bottom of the top plate 5. Side blocks 14 are vertically fixed at both ends of the strip plate 13. The side blocks 14 are drilled with through holes 15, the diameter of which matches the outer diameter of the T-shaped block 17. Multiple upper pressure plates 10 are welded to the front surface of the back plate 6. The number of upper pressure plates 10 is the same as that of the wiring holes 7 and they are located directly above the corresponding wiring holes 7. An arc-shaped hole 24 is milled at the bottom of each upper pressure plate 10. The curved contour of the arc-shaped hole 24 matches the protruding parts on the outer side of the two clamping plates 20.

[0050] This application can be used in the field of power equipment, or in other fields applicable to this application.

[0051] In another embodiment; reference Figure 1-5 A transformer cabinet with a self-locking anti-drop cable clamp is used in the field of power equipment. The cabinet body 1 has arrayed ventilation holes 2 stamped on both side panels, and handles 3 are installed on the outer surface of the cabinet door 4. Slide rails are set on the front and rear inner walls of the cabinet body 1, and the sliding support plate 8 moves horizontally through the slide rails. A U-shaped clearance groove 11 is opened on the top surface of the sliding support plate 8, and the width of the clearance groove 11 is fitted with the thickness of the back plate 6.

[0052] Pulling handle 3 opens cabinet door 4. As cabinet door 4 rotates, it causes fixing block 9 to disengage from T-block 17. T-block 17 moves to the left under the force of the first spring 18 and exits from the insertion hole 15 of side block 14.

[0053] The operator holds the top plate 5 and pulls it upward, causing the back plate 6 to move 200mm upward along the slide rail of the operating hole 25. The sliding support plates 8 on both sides are pulled out horizontally by 150mm, so that the bottom of the back plate 6 is embedded in the relief groove 11 to form a temporary support.

[0054] The cable is introduced into the cabinet 1 through the wiring hole 7, and the lower end of the cable is placed on the corresponding fixing plate 12. After the cable arrangement is completed, the sliding support plate 8 is pushed back, and the back plate 6 is slowly lowered. During the downward pressing of the upper pressure plate 10, the inclined surface of the arc hole 24 presses against the outside of the clamping plate 20, forcing the two sliders 21 to slide towards each other along the slide groove 23 to compress the second spring 22. The clamping plate 20 presses the cable tightly against the surface of the fixing plate 12.

[0055] When the cabinet door 4 is closed, the fixing block 9 pushes the T-shaped block 17 to the right to compress the first spring 18. The T-shaped block 17 is inserted into the socket 15 to lock the side block 14, and the top plate 5 forms a seal with the top of the cabinet 1.
