Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, and in particular to a wiring device for low-voltage engineering. Background Technology

[0002] Low-voltage electrical engineering is a category of electrical applications. Electrical applications can be divided into two categories according to the power transmission capacity: high-voltage and low-voltage. In the field of low-voltage electrical engineering, a large number of wires are used, thus requiring wiring devices to arrange and organize the wires.

[0003] A search revealed that Chinese patent application CN221767496U discloses a wiring device for low-voltage engineering, which can adjust the distance between each group of lines in the low-voltage circuit, making the wiring layout clearer and neater.

[0004] Compared with existing technologies in related fields, it is known that when cutting wires during the wiring process, the cut wires need to be fixed by the staff. Subsequent wiring requires the wires to be unfixed before wiring can proceed, which increases the complexity of the operation and slows down the wiring speed. Utility Model Content

[0005] The purpose of this invention is to provide a wiring device for low-voltage engineering in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A wiring device for low-voltage engineering includes a base, on which a cable storage base and a guide unit are installed. The cable storage base is provided with placement slots, and a fixing unit and a limiting unit are installed in the placement slots. A cable wheel is installed on the fixing unit.

[0008] The limiting unit in the placement slot includes a slider. A bidirectional adjustment mechanism is installed in the placement slot. The slider is installed at both ends of the bidirectional adjustment mechanism. The slider is slidably connected to the wire storage seat. Both sliders are equipped with ratchet seats. A connecting shaft and a non-returning pawl are rotatably installed on the ratchet seats. A ratchet is installed on the part of the connecting shaft located inside the ratchet seat. A guide roller is installed on the connecting shaft. An anti-slip pad is installed on the guide roller. The ratchet is engaged with the non-returning pawl.

[0009] Furthermore, the bidirectional adjustment mechanism in the placement slot includes a bidirectional screw, which is rotatably installed in the placement slot. A handwheel is installed at the upper end of the bidirectional screw, and the two ends of the bidirectional screw have opposite thread directions. The two ends of the bidirectional screw are connected to a slider by threads on their opposite threads.

[0010] Furthermore, the fixing unit in the placement slot includes a mounting base, which is rotatably installed in the placement slot. A reel is mounted on the mounting base, and a lead screw is threadedly connected to the mounting base. The lead screw is slidably connected to the reel, and a limit plate is rotatably mounted on the upper end of the lead screw, with the limit plate located above the reel.

[0011] Furthermore, the guide unit on the base includes a support seat, which is arranged and installed on the base. A mounting bracket is rotatably mounted on the support seat, and a limit ring and a cutting unit are installed on the mounting bracket. The center positions of the limit ring and the guide roller correspond to each other.

[0012] Furthermore, a protective pad is installed on the limit ring.

[0013] Furthermore, the cutting unit on the mounting frame includes a bracket and a slide rod. The bracket is mounted on the mounting frame, and the slide rod is slidably mounted on the bracket. A pressure plate is mounted on the upper end of the slide rod, and a spring is sleeved on the slide rod. A cutter assembly is mounted on the lower end of the slide rod, and the two ends of the spring are respectively connected to the pressure plate and the upper surface of the bracket.

[0014] Furthermore, a baffle is installed inside the placement groove. The baffle is slidably connected to the guide roller and the ratchet seat, and the baffle is located on both sides of the guide roller.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. During wiring, the bidirectional adjustment mechanism limits the wire roller and anti-slip pad to different sizes of wires. The ratchet mechanism, composed of ratchet seat, connecting shaft, ratchet and anti-reverse pawl, ensures that the wire roller can only rotate in one direction. The wire roller and anti-slip pad can clamp the cut wire. When wiring the cut wire, simply pull the wire, reducing the operator's workload and improving the convenience and efficiency of wiring.

[0017] 2. The limiting ring limits and guides the wires in the wiring, isolating them and preventing them from deviating or mixing together. At the same time, due to the rotatable connection between the support and the mounting base, the direction of the limiting ring can be adjusted, allowing it to limit and guide wires in different wiring directions, thus improving ease of use.

Detailed Implementation

[0029] like Figures 1-8As shown, a wiring device for low-voltage engineering includes a base 1, on which a wire storage base 2 and a guide unit 6 are installed. The wire storage base 2 is provided with placement slots 9. A fixing unit 4 and a limiting unit 3 are installed in the placement slots 9. A wire wheel 8 is installed on the fixing unit 4. The fixing unit 4 fixes the wire wheel 8 in the placement slot 9. The limiting slot limits the wire on the wire wheel 8. During wiring, the guide unit 6 limits and guides the wire. After wiring is completed, the limiting unit 3 limits and clamps the cut wire, making it easy to pull the wire again and increasing the convenience of wiring.

[0030] like Figures 3-7 As shown, the limiting unit 3 in the placement groove 9 includes a slider 303. A bidirectional adjustment mechanism is installed in the placement groove 9. The slider 303 is installed at both ends of the bidirectional adjustment mechanism. The slider 303 is slidably connected to the wire storage seat 2. Both sliders 303 are equipped with ratchet seats 304. A connecting shaft 305 and a ratchet pawl 309 are rotatably mounted on the ratchet seats 304. A ratchet 308 is installed on the part of the connecting shaft 305 located inside the ratchet seat 304. A guide roller 306 is installed on the connecting shaft 305. An anti-slip pad 307 is installed on the guide roller 306. The ratchet 308 is engaged with the ratchet pawl 309. According to the size of the wire during wiring, the bidirectional adjustment mechanism drives the slider 303 to move. The slider 303 drives the guide roller 306 to move through the ratchet seats 304 and the connecting shaft 305, adjusting the distance between the two guide rollers 306 so that the guide roller 306... The movable anti-slip pad 307 adheres to the wire, protecting it. The ratchet seat 304, connecting shaft 305, ratchet 308, and anti-reverse pawl 309 combine to form the ratchet 308 mechanism. Due to the anti-reverse pawl 309 limiting the ratchet 308, the guide roller 306 can only rotate in one direction. During wiring, the guide roller 306 limits the wire, and the operator pulls the wire. The wire drives the ratchet 308 to rotate through the anti-slip pad 307 and the guide roller 306. The guide roller 306 and the anti-slip pad 307 do not obstruct the movement of the wire. During the wiring process, when the operator cuts the wire, the anti-slip pad 307 and the guide roller 306 limit the cut wire end, preventing the wire from retracting into the placement groove 9, making it easier for the operator to pull the wire again for wiring, thus improving the convenience and efficiency of the wiring operation.

[0031] like Figures 1-4 , Figure 7As shown, the bidirectional adjustment mechanism in the placement slot 9 includes a bidirectional screw 302, which is rotatably installed in the placement slot 9. A handwheel 301 is installed at the upper end of the bidirectional screw 302. The two ends of the bidirectional screw 302 have opposite thread directions, and the slider 303 is threaded onto the opposite threads at both ends of the bidirectional screw 302. Rotating the handwheel 301 drives the bidirectional screw 302 to rotate, which in turn drives the slider 303 to move, thereby adjusting the position of the slider 303.

[0032] like Figures 1-3 , Figure 6 As shown, the fixing unit 4 in the placement slot 9 includes a mounting base 401, which is rotatably installed in the placement slot 9. A wire wheel 8 is mounted on the mounting base 401, and a lead screw 402 is threadedly connected to the mounting base 401. The lead screw 402 is slidably connected to the wire wheel 8, and a limiting plate 403 is rotatably mounted on the upper end of the lead screw 402. The limiting plate 403 is located above the wire wheel 8. The wire wheel 8 is installed on the mounting base 401, and the mounting base 401 positions and installs the wire wheel 8. After the wire wheel 8 is installed, the lead screw 402 passes through the wire wheel 8 and is threadedly connected to the mounting base 401. The lead screw 402 drives the limiting plate 403 to press against the wire wheel 8, thereby locking and fixing the wire wheel 8. During wiring, the mounting base 401 can rotate to facilitate the wire wheel 8 to lay out the wire.

[0033] like Figure 1 , Figure 3 , Figure 8 As shown, the guide unit 6 on the base 1 includes a support base 601, which is arranged and installed on the base 1. A mounting bracket 602 is rotatably mounted on the support base 601. A limiting ring 603 and a cutting unit 5 are installed on the mounting bracket 602. The center position of the limiting ring 603 and the wire roller 306 are corresponding. The wire passes through the limiting ring 603. During wiring, the limiting ring 603 limits and guides the wires to prevent them from deviating or mixing together, thus isolating them. At the same time, since the support base 601 and the mounting bracket 602 are rotatably connected, the direction of the limiting ring 603 can be adjusted, so that the limiting ring 603 can limit and guide wires in different wiring directions, improving the convenience of use.

[0034] like Figure 3 , Figure 8 As shown, a protective pad 7 is installed on the limiting ring 603. The protective pad 7 protects the wire passing through the limiting ring 603, reduces the friction between the wire and the limiting ring 603 during wiring, and reduces the wear of the wire during wiring.

[0035] like Figures 1-3 , Figure 8As shown, the cutting unit 5 on the mounting bracket 602 includes a bracket 501 and a slide rod 502. The bracket 501 is mounted on the mounting bracket 602, and the slide rod 502 is slidably mounted on the bracket 501. A pressure plate 504 is mounted on the upper end of the slide rod 502, and a spring 503 is sleeved on the slide rod 502. A cutter assembly 505 is mounted on the lower end of the slide rod 502. The two ends of the spring 503 are respectively connected to the pressure plate 504 and the upper surface of the bracket 501. The cutter assembly 505 adopts existing technology. 05 Sliding connection bracket 501: After wiring is completed, when the staff needs to cut the wire, press the pressure plate 504. The pressure plate 504 drives the cutter assembly 505 to move through the slide rod 502. At the same time, the pressure plate 504 compresses the spring 503. The cutter assembly 505 cuts the wire on the mounting bracket 602. After the wire is cut, release the pressure plate 504. Under the elastic force of the spring 503, the spring 503 drives the slide rod 502 and the cutter assembly 505 to reset through the pressure plate 504.

[0036] like Figure 4 , Figure 7 As shown, a baffle 10 is installed in the placement groove 9. The baffle 10 slidably connects the guide roller 306 and the ratchet seat 304. The baffle 10 is located on both sides of the guide roller 306. The baffle 10 limits and guides the guide roller 306 and the ratchet seat 304, improves the stability of the guide roller 306 and the ratchet seat 304 during the adjustment and movement process, and limits the wires on the guide roller 306.

[0037] Working principle: such as Figures 1-3 , Figure 6 As shown, the spool 8 is positioned and installed on the mounting base 401, and the lead screw 402 is threaded through the spool 8 and connected to the mounting base 401. The lead screw 402 drives the limiting plate 403 to press against the spool 8, thereby installing the spool 8 in the placement groove 9.

[0038] like Figures 1-8 As shown, the wire is passed through the wire roller 306 and the limiting ring 603 in sequence. According to the size of the wire, the handwheel 301 is turned, which drives the bidirectional screw 302 to rotate. The bidirectional screw 302 drives the slider 303 to move. The slider 303 drives the wire roller 306 to move through the ratchet seat 304 and the connecting shaft 305. The wire roller 306 drives the anti-slip pad 307 to stick to the wire.

[0039] like Figures 1-8 As shown, during wiring, the worker pulls the wire, which drives the conductor roller 306 and the wire wheel 8 to rotate, so that the wire on the wire wheel 8 is laid out. The wire is limited and guided by the limiting ring 603. Since the support 601 and the mounting bracket 602 are rotatably connected, the limiting ring 603 can limit the wire in different wiring directions.

[0040] like Figures 1-3 , Figure 8 As shown, when the wiring is completed and the staff needs to cut the wire, they press the pressure plate 504. The pressure plate 504 drives the cutter assembly 505 to move through the slide rod 502. At the same time, the pressure plate 504 compresses the spring 503, and the cutter assembly 505 cuts the wire on the mounting bracket 602. After the wire is cut, the pressure plate 504 is released. Under the elastic force of the spring 503, the spring 503 drives the slide rod 502 and the cutter assembly 505 to return to their original positions through the pressure plate 504.

[0041] like Figures 3-7 As shown, when the worker cuts the wire, the anti-slip pad 307 and the guide roller 306 limit the wire end of the cut wire. Due to the ratchet pawl 309 limiting the ratchet 308, the guide roller 306 can only rotate in one direction, so that the guide roller 306 can better clamp and limit the cut wire.
