Description

Technical Field

[0001] The utility model relates to the field of off-line devices, in particular to a safe off-line device. Background Art

[0002] Wires are wires used to transmit electrical energy, mainly consisting of two parts: conductor and insulation layer. When a wire is damaged, it needs to be disassembled and replaced.

[0003] The existing method of wire disassembly is to cut off the current supply, peel off the wire sheath, and then use wire cutters to cut the wire. However, since electrical equipment usually needs to connect multiple wires, when cutting one of the wires, it is necessary to manually fix the wire to be disassembled and then push the surrounding wires away. This operation is inconvenient and affects the efficiency of wire disassembly by the staff.

[0004] Therefore, a safe wire-removing device has been developed that can clamp the wire to be removed and push away the surrounding wires to facilitate workers to cut the wires and improve the efficiency of wire removal. Utility Model Content

[0005] In order to overcome the disadvantages of the existing wire disassembly that the wires need to be fixed manually and then the surrounding wires need to be pushed aside, which is inconvenient and affects the workers' efficiency in disassembling the wires. The utility model provides a safe wire-cutting device that can clamp the wires to be disassembled and push the surrounding wires aside to facilitate the workers to cut the wires, thereby improving the wire disassembly efficiency.

[0006] The technical solution is: a safe disconnection device, including a handle, a first bidirectional screw, a guide rod, a main shaft, an outer cover box, a motor, a second bidirectional screw, a clamp and an anti-interference mechanism. The first bidirectional screw is rotatably connected to the right side of the handle, and the right part of the handle is connected to the guide rod. The upper and lower parts of the first bidirectional screw are threadedly connected to the main shaft, and the main shaft is slidably connected to the guide rod. The right side of the main shaft is connected to the outer cover box, the front side of the outer cover box is connected to the motor, and the second bidirectional screw is connected to the motor output shaft. The second bidirectional screw is rotatably connected to the adjacent outer cover box, the front and rear parts of the second bidirectional screw are threadedly connected to the clamp, and the clamp is slidably connected to the adjacent outer cover box. The outer cover box is provided with an anti-interference mechanism that can prevent interference from other wires.

[0007] As an improvement of the above-mentioned scheme, the anti-interference mechanism includes a slider and a paddle. The front and rear parts of the second bidirectional screw are both threadedly connected with the slider, the sliders are both located on the outsides of adjacent clamps, the sliders are connected with paddles, the paddles are both slidably connected to adjacent outer cover boxes, the paddles are both in contact with adjacent clamps, and when the clamps slide close to each other, the sliders are moved away from each other through the reverse threads in the sliders, driving the paddles to move away from each other, so that the paddles can push away the wires around the wires to be removed.

[0008] As an improvement of the above scheme, a protective mechanism is also included, which includes a ring, a baffle and a pin. The right part of the main shaft is connected to the ring, and the front and rear sides of the ring are rotatably connected to the baffle, and the baffle is connected to the pin. When cutting the wire to be removed, the baffle is rotated to make the baffle perpendicular to the ring, so that the baffle shields the wire to be removed.

[0009] As an improvement of the above solution, a handle is connected to the upper side of the first bidirectional screw rod.

[0010] As an improvement of the above solution, a limit block is provided on the lower side of the first bidirectional screw rod.

[0011] As an improvement to the above solution, clamping blocks are provided on the clamping plates.

[0012] The beneficial effects are as follows: 1. The utility model allows the clamping plates to slide towards each other while the reverse threads in the sliders allow the sliders to move away from each other, driving the paddles to move away from each other, so that the paddles can push aside the wires around the wires to be removed, thereby achieving the effect of clamping the wires to be removed and pushing aside the surrounding wires, making it easier for staff to cut off the wires, thereby improving the efficiency of wire removal.

[0013] 2. The utility model rotates the baffle plate when cutting the wire to be removed, so that the baffle plate is perpendicular to the ring, so that the baffle plate shields the wire to be removed, thereby preventing arc splashing and avoiding harm to workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] A safety disconnection device, such as Figure 1 and Figure 2 As shown, it includes a handle 1, a first bidirectional screw rod 2, a guide rod 3, a main shaft 4, an outer cover box 40, a motor 5, a second bidirectional screw rod 6, a clamping plate 7 and an anti-interference mechanism 8. The first bidirectional screw rod 2 is rotatably connected to the right side of the handle 1, and the right part of the handle 1 is connected to the guide rod 3. The upper and lower parts of the first bidirectional screw rod 2 are both threadedly connected to the main shaft 4, and the main shaft 4 is slidably connected to the guide rod 3. The upper side of the first bidirectional screw rod 2 is connected to a grip for easy rotation. A limit block is provided on the lower side of the first bidirectional screw rod 2 for easy limiting. The right side of the main shaft 4 is connected to the outer cover box 40, and the front side of the outer cover box 40 is connected to the motor 5. The second bidirectional screw rod 6 is connected to the output shaft of the motor 5. The second bidirectional screw rod 6 is rotatably connected to the adjacent outer cover box 40. The front and rear parts of the second bidirectional screw rod 6 are threadedly connected to the clamping plate 7, and the clamping block is provided on the clamping plate 7 for clamping the wire. The clamping plate 7 is slidably connected to the adjacent outer cover box 40, and the outer cover box 40 is provided with an anti-interference mechanism 8.

[0021] like Figure 1 and Figure 3 As shown, the anti-interference mechanism 8 includes a slider 81 and a paddle 82. The front and rear parts of the second bidirectional screw 6 are threadedly connected to the slider 81. The sliders 81 are located on the outside of the adjacent clamping plates 7. The sliders 81 are connected to the paddles 82. The paddles 82 are slidably connected to the adjacent outer cover box 40, and the paddles 82 are in contact with the adjacent clamping plates 7.

[0022] When using the utility model, first rotate the first bidirectional screw rod 2 according to the length of the wire to be removed, and drive the main shaft 4 to move closer to or away from each other on the guide rod 3 through the thread, adjust the distance between the main shafts 4 so that the distance between the main shafts 4 corresponds to the length of the wire to be removed. After the adjustment, grasp the handle 1 and move the clamping plate 7 to the wire to be removed so that the wire to be removed is located between the clamping plates 7. Then start the motor 5 to drive the second bidirectional screw rod 6 to rotate, so that the clamping plates 7 slide closer to each other on the outer cover box 40 to clamp the wire. When the clamping plates 7 slide closer to each other, the reverse threads in the sliders 81 make the sliders 81 move away from each other, driving the paddles 82 to move away from each other, so that the paddles 82 can pry apart the wires around the wire to be removed, thereby clamping the wire to be removed and prying apart the surrounding wires, so that the staff can cut the wires and improve the efficiency of wire removal.

[0023] like Figure 1 and Figure 4 As shown, a protection mechanism 9 is also included, which includes a collar 91, a baffle 92 and a latch 93. The right part of the main shaft 4 is connected to the collar 91, and the front and rear sides of the collar 91 are rotatably connected to the baffle 92, and the baffle 92 is connected to the latch 93.

[0024] The protective mechanism 9 of the device can prevent arc splashing. When the wire to be removed is cut off, the baffle 92 is rotated to make the baffle 92 perpendicular to the ring 91, so that the baffle 92 shields the wire to be removed, thereby preventing the arc from splashing and avoiding harm to the staff. After the wire to be removed is cut off, the baffle 92 is rotated to make the pin 93 engage with the ring 91 to fix the baffle 92.
