Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a device for fixing internal wiring in a control cabinet. Background Technology

[0002] A control cabinet is a cabinet-like device used to centrally install electrical components, control equipment, and related components. It is mainly used to control, protect, monitor, and manage power systems, industrial equipment, or automated processes. Through reasonable layout and electrical connections, circuit breakers, contactors, relays, controllers, instruments, and sensor components are integrated into a closed or semi-closed cabinet to form a complete control unit.

[0003] The internal wiring fixing device of the control cabinet refers to the functional component installed inside the control cabinet to organize, fix and protect the electrical wiring, and ensure that the wiring layout is standardized, the connection is reliable and the operation is safe. Through physical constraints and structured layout, it avoids the failure of wires due to shaking, pulling, wear or electromagnetic interference.

[0004] Existing fixing devices enclose the wires in an independent space to prevent them from directly contacting the metal cabinet or tangling and rubbing against each other, thus reducing the risk of short circuits caused by insulation damage. However, when the wire harness diameter is large, using small-gauge cable ties can lead to loosening of the wire harness due to insufficient binding force, or damage to the insulation layer due to excessive tightening. Current technology uses wire clamps with spring buffers in high-vibration scenarios such as machine tool control cabinets. The spring deformation absorbs vibration energy and reduces the impact force on the wire harness. However, when multiple wire harnesses are fixed individually, uneven force can cause shaking or mutual friction. Traditional clamps need to be installed one by one, which cannot guarantee synchronous clamping. Utility Model Content

[0005] The purpose of this utility model is to provide a device for fixing the internal wiring of a control cabinet, which solves the problem of having to install each wire individually and being unable to guarantee synchronous clamping.

[0006] To achieve the above objectives, this utility model provides a control cabinet internal wiring fixing device. (The control cabinet internal wiring fixing device includes a cabinet body, a back plate fixedly connected to the rear side of the inner wall of the cabinet body, and multiple mounting blocks equidistantly arranged on the front side of the outer wall of the back plate. Each mounting block has a fixing mechanism inside it for fixing data cables. A disassembly mechanism is provided on the rear side of the outer wall of the mounting block for disassembling and repairing the mounting block. The fixing mechanism includes clamping blocks, with multiple clamping blocks equidistantly arranged on the inner side of the outer wall of the mounting block. A connecting shaft is fixedly connected to the middle of the front side of the outer wall of each of the left and right clamping blocks. A connecting block is rotatably connected to the outer wall of each connecting shaft. Two connecting blocks are rotatably connected to the outer walls of two connecting blocks on opposite sides. A connecting shaft is rotatably connected to the middle of the outer wall of each connecting block. Multiple connecting shafts are fixedly connected to the middle of the front side of the outer wall of the clamping block. A fixing block is fixedly connected to the upper middle part of the front side of the outer wall of the right clamping block. A drive assembly is provided inside the mounting block.)

[0007] The drive assembly includes a crank handle, which is located at the center of the front side of the outer wall of the mounting block. A rotating shaft is fixedly connected to the rear side of the outer wall of the crank handle. A gear is fixedly connected to the end of the rotating shaft. A rack is meshed with the top wall of the gear. The rack is fixedly connected to the bottom wall of the mounting block.

[0008] The disassembly mechanism includes a slide groove, which is located on the front side of the outer wall of the mounting block. A locking block is installed inside the slide groove. Telescopic rods are fixedly connected to the front and rear ends of adjacent sides of the outer walls of the two locking blocks. Springs are installed on the outer walls of the telescopic rods. Circular grooves are opened on the front and rear ends of adjacent sides of the inner walls of the multiple slide grooves. The telescopic rods are located inside the circular grooves. A slot is opened on the front side of the outer wall of the back plate. A sliding component is installed inside the mounting block.

[0009] The sliding assembly includes a slider 1, and multiple sliders 1 are fixedly connected to the upper and lower ends and front and rear sides of the outer wall of the locking block. The upper and lower ends and front and rear sides of the inner wall of the sliding groove 1 are provided with sliding grooves 2, and the sliding grooves 2 are slidably connected to the slider 1.

[0010] (The rotating shaft is rotatably connected to the middle of the front side of the outer wall of the mounting block, and the bottom wall of the fixing block is fixedly connected to the right end of the top wall of the rack).

[0011] (The first slide groove is slidably connected to the locking block, and the locking block engages with the slot).

[0014] This utility model discloses a wiring fixing device for an internal control cabinet. 1. In this utility model, when fixing the wire harness, the crank handle is operated to make the rotating shaft and gear rotate simultaneously, thereby moving the rack and driving the fixing block and the right clamping block to move synchronously. The movement of the right clamping block is transmitted to the connecting block 1 through the connecting shaft 1.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please see Figure 2 and Figure 3This utility model provides an embodiment of a control cabinet internal wiring fixing device, including a cabinet body 1. A back plate 2 is fixedly connected to the rear side of the inner wall of the cabinet body 1. Multiple mounting blocks 3 are equidistantly arranged on the front side of the outer wall of the back plate 2. A fixing mechanism 4 is provided inside the mounting block 3 for fixing the wiring harness. A disassembly mechanism 5 is provided on the rear side of the outer wall of the mounting block 3 for disassembling and repairing the mounting block 3. The fixing mechanism 4 includes clamping blocks 401. Multiple clamping blocks 401 are equidistantly arranged on the inner side of the outer wall of the mounting block 3. The middle of the front side of the outer wall of the left and right clamping blocks 401 is fixedly connected to... There is a connecting shaft 402, and a connecting block 403 is rotatably connected to the outer wall of the connecting shaft 402. The movement of the clamping block 401 on the right side is transmitted to the connecting block 403 through the connecting shaft 402. Two connecting blocks 404 are rotatably connected to the outer walls of the two connecting blocks 403 on opposite sides. A connecting shaft 405 is rotatably connected to the middle of the outer wall of the connecting block 404. The connecting blocks 403 drive the connecting blocks 404 to rotate around the connecting shaft 405. Multiple connecting shafts 405 are fixedly connected to the middle of the front side of the outer wall of the clamping block 401. The connecting shafts 405 drive the clamping blocks 401 in the middle, etc. To ensure synchronous movement, a fixing block 406 is fixedly connected to the upper middle part of the front side of the outer wall of the right clamping block 401. A drive assembly 407 is installed inside the mounting block 3. The drive assembly 407 includes a crank 4071, which is located in the middle of the front side of the outer wall of the mounting block 3. A rotating shaft 4072 is fixedly connected to the rear side of the outer wall of the crank 4071. The crank 4071 drives the rotating shaft 4072 to rotate. A gear 4073 is fixedly connected to the end of the rotating shaft 4072, driving the gear 4073 to rotate. A rack 4074 is meshed with the top wall of the gear 4073. The gear 4073 transmits... The rack 4074 above moves and is fixedly connected to the bottom wall of the fixed block 406. The rack 4074 drives the fixed block 406 and the right clamping block 401 to move synchronously. The rotating shaft 4072 is rotatably connected to the middle of the front side of the outer wall of the mounting block 3. The rotating shaft 4072 is located in the middle of the front side of the mounting block 3 to avoid uneven force and shaking caused by eccentric transmission. The bottom wall of the fixed block 406 is fixedly connected to the right end of the top wall of the rack 4074. The rack 4074 drives the right end clamping block 401 on the fixed block 406 to move. The fixed block 406 drives the left end clamping block 401 to move synchronously and equidistantly.

[0026] Specifically, the fixing mechanism 4 is used to fix the wire harness, and the disassembly mechanism 5 is used to disassemble and inspect the mounting block 3. During the fixing of the wire harness, the crank handle 4071 is first turned. The crank handle 4071 drives the rotating shaft 4072 to rotate. The rotation of the rotating shaft 4072 then drives the gear 4073 to rotate. The gear 4073 meshes with the rack 4074 above, causing the rack 4074 to move. This, in turn, causes the fixing block 406 and the right clamping block 401 to move together. The displacement of the right clamping block 401 is transmitted through the connecting shaft 402. Connecting block 403 drives connecting block 404 to rotate around connecting shaft 405, thereby enabling multiple clamping blocks 401 on the left to move synchronously at equal distances. The multiple clamping blocks 401 can open and close synchronously, thus completing the clamping or releasing operation of the wire harness. The rotating shaft 4072 is located in the middle of the front side of the mounting block 3 to avoid uneven force and shaking caused by eccentric transmission. The rack 4074 drives the right clamping block 401 on the fixed block 406 to move, and the fixed block 406 drives the left clamping block 401 to move synchronously at equal distances.

[0027] Please see Figure 3 , Figure 4 and Figure 5 The disassembly mechanism 5 includes a slide groove 501, which is located on the front side of the outer wall of the mounting block 3. A locking block 502 is installed inside the slide groove 501. Telescopic rods 503 are fixedly connected to the front and rear ends of adjacent sides of the outer walls of two locking blocks 502. The telescopic rods 503 are telescopic, and springs 504 are installed on the outer walls of the telescopic rods 503 to return the locking blocks 502. Circular grooves 506 are formed on the front and rear ends of adjacent sides of the inner walls of the multiple slide grooves 501. The telescopic rods 503 are located inside the circular grooves 506 and retract within them. A slot 505 is formed on the front side of the outer wall of the back plate 2. 5 is used to fix the locking block 502. The mounting block 3 is provided with a sliding component 507. The sliding component 507 includes a slider 5071. Multiple sliders 5071 are fixedly connected to the upper and lower ends and the front and rear sides of the outer wall of the locking block 502. The upper and lower ends and the front and rear sides of the inner wall of the slider 501 are provided with a second slider 5072. The second slider 5072 is slidably connected to the slider 5071. The slider 5071 slides on the second slider 5072 to ensure that the movement of the locking block 502 is smooth. The first slider 501 is slidably connected to the locking block 502. The locking block 502 is engaged with the slot 505. The locking block 502 is engaged into the slot 505 of the back plate 2.

[0028] Specifically, during the installation of mounting block 3, locking block 502 needs to be aligned with slot 505 and inserted. Locking block 502 pushes telescopic rod 503 to retract so that locking block 502 can be inserted into slot 505 of back plate 2. Subsequently, the rebound force of spring 504 fixes locking block 502, thereby ensuring that mounting block 3 is firmly fixed on back plate 2. Slider 1 5071 slides on slide groove 2 5072 to ensure smooth movement of locking block 502. If mounting block 3 needs to be removed, both locking blocks 502 should be pressed at the same time to compress spring 504, causing telescopic rod 503 to retract in circular groove 506, thereby causing locking block 502 to disengage from slot 505, and mounting block 3 can then be removed from back plate 2.

[0029] Please see Figure 1 , Figure 3 and Figure 4 Multiple sliding grooves 501 are provided on the left and right ends of the front side of the outer wall of the mounting block 3, and multiple slots 505 are provided at equal intervals on the left and right ends of the front side of the outer wall of the back plate 2. The sliding grooves 501 and slots 505 are distributed at equal intervals on the left and right ends of the mounting block 3 and the back plate 2, so that when the mounting block 3 is engaged with the slots 505 by the locking block 502, the force on the left and right sides is balanced, avoiding tilting or shaking caused by unilateral fixation, and ensuring that the mounting block 3 is firmly connected to the back plate 2. The upper and lower ends of the inner wall of the mounting block 3 are provided with sliding grooves 7. The inner wall of the sliding grooves 7 is slidably connected to the sliders 6. The clamping block 401 is fixedly connected to the adjacent side of the outer wall of the multiple sliders 6. The direct sliding connection between the sliding grooves 7 and the sliders 6 reduces the friction when the clamping block 401 moves, making the clamping force transmission more direct and efficient.

[0030] Specifically, the slide groove 501 and the slot 505 are equidistantly distributed at the left and right ends of the mounting block 3 and the back plate 2, so that when the mounting block 3 is engaged with the slot 505 by the locking block 502, the force on the left and right sides is balanced, avoiding tilting or shaking caused by unilateral fixation, and ensuring that the mounting block 3 is firmly connected to the back plate 2. The direct sliding connection between the slide groove 7 and the slider 6 reduces the friction when the clamping block 401 moves, making the clamping force transmission more direct and efficient.

[0031] Working principle: When it is necessary to fix the wire harness, turn the crank handle 4071. The crank handle 4071 drives the rotating shaft 4072 to rotate. The rotating shaft 4072 drives the gear 4073 to rotate. The gear 4073 drives the rack 4074 above to move. The rack 4074 drives the fixing block 406 and the right clamping block 401 to move synchronously. The movement of the right clamping block 401 is transmitted to the connecting block 403 through the connecting shaft 1 402. The connecting block 1 403 drives the connecting block 2 404 to rotate around the connecting shaft 2 405, so that the multiple clamping blocks 401 on the left side move synchronously at equal distances. This realizes the synchronous opening and closing action of multiple clamping blocks 401, ensuring consistency when fixing multiple wire harnesses, reducing the relative displacement between wire harnesses, reducing the risk of wear, and can clamp a single thick wire harness or multiple thin wire harnesses at the same time.

[0032] When installing mounting block 3, locking block 502 is aligned with and inserted into slot 505. Locking block 502 pushes telescopic rod 503 to retract, so that locking block 502 is locked into slot 505 of back plate 2. Spring 504 rebounds locking block 502, thereby firmly fixing mounting block 3 to back plate 2. At this time, slider 1 5071 slides along slide groove 2 5072 to ensure that locking block 502 moves smoothly. When it is necessary to remove mounting block 3, press both locking blocks 502 at the same time to compress spring 504, so that telescopic rod 503 retracts into circular groove 506, and locking block 502 disengages from slot 505. At this time, mounting block 3 can be removed from back plate 2.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
