Abstract
Description
Technical Field
[0001] This utility model relates to the field of power engineering technology, and in particular to a rapid stripping device for power engineering cables. Background Technology
[0002] A cable consists of one or more conductors, all wrapped with an insulating protective layer. Cables are frequently used in electrical construction. During use, the insulation at the connection points needs to be stripped before connecting two cables. Currently, wire strippers are typically used to strip the outer insulation of cables; the user must apply force to the strippers to cut the outer insulation.
[0003] When using wire strippers to cut the outer insulation layer of a cable, the insulation layer must first be circumferentially cut to allow it to be severed. Then, the insulation layer can be pushed off the conductor. However, pushing the insulation layer can easily pull the conductor along with it. If too much force is applied to the insulation layer, the conductor may break, requiring the insulation to be stripped again, which reduces work efficiency. Utility Model Content
[0004] In view of this, the present invention provides a fast stripping device for power engineering cables, the main technical problem to be solved is: solving the problem that excessive force in pushing the insulation layer can easily break the conductor.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fast cable stripping device for power engineering, comprising a fixed frame, a pressure frame movably connected to the upper part of the fixed frame, pressure cylinders fixedly connected to the lower right side of the pressure frame and the inner right side of the fixed frame, a fixed box fixedly connected to the lower left side of the fixed frame and the lower left side of the pressure frame, a stripping device placed inside the fixed box, the stripping device comprising a connecting block placed inside the fixed box, a locking block movably connected inside the connecting block, a compression spring fixedly connected between the connecting block and the locking block, and a cutter and a cutting sleeve fixedly connected to the side of the connecting block away from the fixed box.
[0006] By adopting the above technical solution, during use, the connecting block is aligned with the box and pressed inward. The pressing causes the locking block to retract into the connecting block, allowing the connecting block to smoothly enter the box. Once the connecting block is fully inside the box, the locking block is engaged in the box by the compression spring, thus fixing the stripping device. Then, the cable is inserted from left to right between the stripping device and the pressure cylinder. Pressing down on the pressure frame moves the stripping device downward, allowing the cutter and cutting sleeve to contact the cable. The cutting sleeve cuts the outer insulation layer of the cable by pressing, and pulling the cable to the left cuts the insulation layer, making it easier for the insulation layer to detach from the conductor. This prevents the conductor from being easily broken due to excessive force applied to the insulation layer.
[0007] As a further description of the above technical solution: the fixed frame includes a frame body, and the top of the frame body is provided with a through hole.
[0008] By adopting the above technical solution, the through hole is used for raising and lowering the pressure column.
[0009] As a further description of the above technical solution: the fixed box includes a box body fixedly connected to the lower left side of the frame and the lower left side of the pressure frame, and pressure blocks are movably connected to both the front and rear sides of the box body.
[0010] By adopting the above technical solution, pressing the middle pressing block simultaneously allows it to push the locking block. Continuous pushing causes the locking block to retract into the connecting block, thereby allowing the connecting block to be removed from the box. This facilitates the removal and replacement of the peeling device.
[0011] As a further description of the above technical solution: the pressure cylinder includes a fixed shaft fixedly connected to the lower right side of the pressure frame and the inner right side of the fixed frame. A limit block is fixedly connected to the outside of the fixed shaft. A cylinder body is movably connected to the outside of the fixed shaft and the limit block. A limit groove is provided on the outside of the cylinder body. A tightening device is fixedly connected to the inside of the cylinder body.
[0012] By adopting the above technical solution, the limiting block is used to limit the position of the cylinder, the limiting groove is used to place the cable, and the clamping device is used to clamp the fixed shaft, so that the cylinder cannot easily rotate outside the fixed shaft.
[0013] As a further description of the above technical solution: the clamping device includes a fixed cylinder fixedly connected to the inside of the cylinder body, a top block movably connected inside the fixed cylinder, a clamping spring fixedly connected between the fixed cylinder and the top block, a top column fixedly connected to the side of the top block near the fixed shaft, a connecting plate fixedly connected to the outer end of the top column, and an anti-slip plate fixedly connected to the side of the connecting plate near the fixed shaft.
[0014] By adopting the above technical solution, when stripping the cable, pressing down on the pressure frame allows the upper pressure cylinder to move downwards, thereby pressing the cable down with the two pressure cylinders. When pulling the cable, the anti-slip plate can firmly press against the fixed shaft under the action of the tightening spring, thereby increasing the resistance when the cylinder rotates, and thus straightening the pulled cable, ensuring that the cutter and cutting sleeve will not easily scratch the conductor due to the bending of the cable.
[0015] As a further description of the above technical solution: the pressure frame includes a pressure column movably connected inside the frame, a pressure plate is fixedly connected to the lower part of the pressure column, a connecting column is fixedly connected to the right side of the lower part of the pressure plate, a handle is fixedly connected to the top of the pressure column, a stop block is fixedly connected to the outer side of the pressure column, and a return spring is fixedly connected between the stop block and the frame.
[0016] By adopting the above technical solution, pressing the handle can drive the pressure column to move downward. At this time, the stop block will squeeze the return spring. When the external force is removed, the return spring will allow it to return to its original position, making it easy to strip the cable again.
[0017] By employing the above technical solution, the present invention provides a fast cable stripping device for power engineering, which has at least the following beneficial effects:
[0018] Compared with existing technologies, this rapid cable stripping device for power engineering, by incorporating a stripping mechanism, helps to prevent the metal conductor from being broken when pushing the insulation layer. In use, the connecting block is aligned with the housing and pressed inwards. This pressing causes the locking block to retract into the connecting block, allowing it to smoothly enter the housing. Once fully inside, the locking block is engaged by a compression spring, securing the stripping device. The cable is then inserted from left to right between the stripping device and the pressure cylinder. Pressing down on the pressure frame moves the stripping device downwards, allowing the cutter and cutting sleeve to contact the cable. The cutting sleeve cuts the outer insulation layer of the cable through compression, and pulling the cable to the left causes the cutter to cleave the insulation layer, making it easier for the insulation to detach from the conductor without breaking the conductor due to excessive force applied to the insulation layer.

[0027] Reference Figure 1-6This utility model provides a quick cable stripping device for power engineering: It includes a fixed frame 1, a pressure frame 5 movably connected to the upper part of the fixed frame 1, pressure cylinders 4 fixedly connected to the lower right side of the pressure frame 5 and the inner right side of the fixed frame 1, and a fixed box 3 fixedly connected to the lower left side of the fixed frame 1 and the lower left side of the pressure frame 5. A stripping device 2 is placed inside the fixed box 3. The stripping device 2 includes a connecting block 201 placed inside the fixed box 3, a locking block 203 movably connected inside the connecting block 201, and the locking block 203 can move inside the connecting block 201. A compression spring 202 is fixedly connected between the connecting block 201 and the locking block 203. A cutter 204 and a cutting sleeve 205 are fixedly connected to the side of the connecting block 201 away from the fixed box 3. In use, by aligning the connecting block 201 with the box 301 and pressing it inwards, the locking block 204 is pressed. 03 can retract into the interior of the connecting block 201, allowing the connecting block 201 to smoothly enter the interior of the box 301. After the connecting block 201 is fully inside the box 301, the clamping block 203 can be clamped into the box 301 under the action of the compression spring 202, thereby fixing the stripping device 2. Then, the cable is inserted from left to right between the stripping device 2 and the pressure cylinder 4. By pressing down the pressure frame 5, the stripping device 2 above can move downward. By continuously moving downward, the cutter 204 and the cutting sleeve 205 can contact the cable. By squeezing, the outer insulation layer of the cable can be cut by the cutting sleeve 205. By pulling the cable to the left, the cutter 204 can cut open the insulation layer, making it easier for the insulation layer to detach from the wire. The wire will not be easily broken due to excessive force pushing the insulation layer.
[0028] Furthermore, the fixed frame 1 includes a frame body 101, and the top of the frame body 101 is provided with a through hole 102 for the lifting and lowering of the pressure column 504.
[0029] Furthermore, the fixing box 3 includes a box body 301 fixedly connected to the lower left side of the frame 101 and the lower left side of the pressure frame 5. Pressure blocks 302 are movably connected to both the front and rear sides of the box body 301. The pressure blocks 302 can move inside the box body 301. By pressing the pressure blocks 302 towards the middle at the same time, they can push the locking block 203. By continuously pushing, the locking block 203 can retract into the interior of the connecting block 201, thereby allowing the connecting block 201 to be removed from the box body 301, which facilitates the removal of the peeling device 2 and the replacement of the peeling device 2.
[0030] Furthermore, the pressure cylinder 4 includes a fixed shaft 401 fixedly connected to the lower right side of the pressure frame 5 and the inner right side of the fixed frame 1. The cylinder body 404 can rotate outside the fixed shaft 401. A limit block 402 is fixedly connected to the outside of the fixed shaft 401. The limit block 402 is used to limit the position of the cylinder body 404. The cylinder body 404 is movably connected to the outside of the fixed shaft 401 and the limit block 402. A limit groove 405 is provided on the outside of the cylinder body 404. The limit groove 405 is used for placing the cable. A tightening device 403 is fixedly connected to the inside of the cylinder body 404. The tightening device 403 is used to tighten the fixed shaft 401, so that the cylinder body 404 cannot easily rotate outside the fixed shaft 401.
[0031] Furthermore, the clamping device 403 includes a fixed cylinder 4031 fixedly connected to the inner side of the cylinder body 404. A top block 4033 is movably connected inside the fixed cylinder 4031. A clamping spring 4032 is fixedly connected between the fixed cylinder 4031 and the top block 4033. A top column 4034 is fixedly connected to the side of the top block 4033 near the fixed shaft 401. The top block 4033 and the top column 4034 can move inside the fixed cylinder 4031, and under the action of the clamping spring 4032, the anti-slip plate 4036 can firmly press against the fixed shaft 401. A connecting plate is fixedly connected to the outer end of the top column 4034. 4035, the connecting plate 4035 is fixedly connected to the anti-slip plate 4036 on the side near the fixed shaft 401. When stripping the cable, pressing down on the pressure frame 5 causes the upper pressure cylinder 4 to move downward, so that the two pressure cylinders 4 can press down on the cable. When pulling the cable, the anti-slip plate 4036 can firmly press against the fixed shaft 401 under the action of the tightening spring 4032, so that the resistance when the cylinder 404 rotates increases, so that the pulled cable can be straightened, ensuring that the cutter 204 and the cutting sleeve 205 will not easily scratch the wire due to the bending of the cable.
[0032] Furthermore, the pressure frame 5 includes a pressure column 504 movably connected inside the frame 101. The pressure column 504 can be raised and lowered inside the frame 101. A pressure plate 505 is fixedly connected to the lower part of the pressure column 504. A connecting column 506 is fixedly connected to the right side of the lower part of the pressure plate 505. The connecting column 506 is used to fix the upper pressure cylinder 4. A handle 501 is fixedly connected to the top of the pressure column 504. A stop block 502 is fixedly connected to the outside of the pressure column 504. A return spring 503 is fixedly connected between the stop block 502 and the frame 101. Pressing the handle 501 causes it to move the pressure column 504 downward. At this time, the stop block 502 will squeeze the return spring 503. When the external force is removed, the return spring 503 will cause it to return to its original position, making it easy to strip the cable again.
[0033] Working principle: During use, the connecting block 201 is aligned with the box 301 and pressed inward. The pressing causes the locking block 203 to retract into the connecting block 201, allowing the connecting block 201 to smoothly enter the box 301. Once the connecting block 201 is fully inside the box 301, the locking block 203 is locked into the box 301 by the action of the compression spring 202, thus fixing the stripping device 2. Then, the cable is inserted from left to right between the stripping device 2 and the pressure cylinder 4. By pressing down the pressure frame 5, the stripping device 2 moves downward. As it moves downward, the cutter 204 and the cutting sleeve 205 come into contact with the cable. The cutting sleeve 205 cuts the outer insulation layer of the cable by pressing. By pulling the cable to the left, the cutter 204 cuts open the insulation layer, making it easier for the insulation layer to detach from the wire. This prevents the wire from being easily broken due to excessive force pushing the insulation layer.
