Description

Technical Field

[0001] This utility model relates to the field of cable pipe cutting equipment technology, and in particular to a limiting structure based on a rigid polyvinyl chloride cable pipe cutting device. Background Technology

[0002] Rigid PVC cable conduit is a cable protection pipe made primarily of PVC resin with appropriate additives, processed through extrusion and other processes. It boasts advantages such as high mechanical strength, strong corrosion resistance, good insulation performance, and low cost. It effectively protects cables from external mechanical damage and chemical corrosion, and is widely used in cable laying projects in the power and telecommunications industries.

[0003] Currently, it is difficult to effectively limit the cable conduit of any size because there are many specifications and large differences in diameter of cable conduits at the construction site. Existing limiting structures are often only applicable to cable conduits within a specific size range. For cable conduits that exceed their design size range, they cannot be tightly fitted and fixed, which causes the cable conduit to shake and shift during the cutting process, seriously affecting the cutting accuracy. This may result in inconsistent cable conduit lengths and uneven cuts after cutting, which in turn affects subsequent cable laying and installation work. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a limiting structure based on a rigid polyvinyl chloride cable pipe cutting device.

[0005] This utility model is achieved using the following technical solution: a limiting structure based on a rigid polyvinyl chloride cable pipe cutting device, comprising a cutting machine body, with limiting components symmetrically arranged on both sides of the cutting machine body for limiting cable pipes of different thicknesses, and a lifting component below each limiting component capable of raising or lowering adjacent limiting components, the limiting component comprising a first limiting plate disposed on one side of the cutting machine body, and a second limiting plate rotatably mounted on one side of the first limiting plate, the first limiting plate and the second limiting plate being arranged in a semi-circular ring shape.

[0006] Through the above technical solution, the semi-circular ring structure composed of the first limiting plate and the second limiting plate can be opened or closed by rotation according to the thickness of the cable pipe, so as to achieve preliminary adaptation and limiting of cable pipes of different diameters. Compared with the traditional limiting structure, it can better adapt to cable pipes of various sizes.

[0007] As a further improvement of the above solution, a plurality of moving columns arranged in a "C" shape are provided inside the ring formed by the first limiting plate and the second limiting plate. A rubber column is rotatably sleeved on each moving column. Both ends of each moving column penetrate through the adjacent first limiting plate or the second limiting plate. A plurality of pushing plates are provided outside the ring formed by the first limiting plate and the second limiting plate. Each pushing plate is fixedly installed at both ends of the adjacent moving column.

[0008] Through the above technical solution, when it is necessary to further fix the cable pipe, push the pushing plate. The pushing plate drives the moving column to move, and the rubber column on the moving column随之移动并与电缆管表面接触, the rubber column can not only increase the friction force with the cable pipe to prevent the cable pipe from sliding back and forth during the cutting process, but also the design of the rotatable sleeve allows the cable pipe to rotate during the cutting process, adapting to more cable pipe cutting methods.

[0009] As a further improvement of the above solution, a threaded column is provided on one side of each pushing plate. One end of each threaded column threadedly penetrates through the adjacent pushing plate and is rotatably installed with a connecting block. Each connecting block is fixedly installed on the adjacent first limiting plate or the second limiting plate. The other end of each threaded column is fixedly installed with a rotating block. A nut is threadedly sleeved on each threaded column.

[0010] Through the above technical solution, rotate the rotating block, and the threaded column随之转动. Since the threaded column is threadedly connected to the pushing plate, the pushing plate will move under the action of the threaded column, thereby precisely adjusting the extrusion force of the rubber column on the cable pipe. After the adjustment is completed, tighten the nut to fix the position of the pushing plate, ensuring that the limiting effect of the rubber column on the cable pipe during the cutting process is stable and reliable, and achieving precise limiting and fixing of the cable pipe.

[0011] As a further improvement of the above solution, a first connecting plate is fixedly installed at the bottom of the cutting machine main body. The lifting component includes a first support plate fixedly installed at the top of one end of the first connecting plate. A second support plate is slidably sleeved on the first support plate. The top of the second support plate is fixedly installed with the adjacent second limiting plate.

[0012] Through the above technical solution, the second support plate can slide on the first support plate, thereby adjusting the height of the limiting component to adapt to cable pipes with different placement heights, further improving the versatility of the present limiting structure, and ensuring effective limiting of the cable pipe in various construction scenarios.

[0013] As a further improvement of the above solution, a plurality of first fixing holes penetrating through itself are provided on the first support plate. A second fixing hole penetrating through itself is provided on the second support plate. One side of the second support plate is provided with a fixing plate arranged in an "L" shape. One side of the fixing plate passes through the adjacent first fixing hole and the second fixing hole. It should be noted that there are some inaccurate expressions in the original text such as "随之移动并与电缆管表面接触" and "随之转动" which are not accurately translated in the above content. You may need to further correct and refine these parts according to the actual situation.

[0014] With the above technical solution, after adjusting the height of the second support plate on the first support plate, insert the fixing plate into the corresponding first fixing port and second fixing port, and the position of the second support plate can be fixed, preventing the limiting component from moving up and down during the cutting process, ensuring the stability of the limit, and thus ensuring the smooth progress of the cutting work.

[0015] As a further improvement of the above solution, a second connecting plate fixedly installed with the bottom of the cutting machine main body is provided on one side of the first connecting plate. Both ends of the top of the second connecting plate are fixedly installed with third support plates. A sliding groove is provided on one side of the top of each of the two third support plates. A third limiting plate arranged in a "C" shape is provided between the two third support plates. The third limiting plate is slidably matched with the two third support plates through the sliding groove. Limiting rods are provided at the bottoms of both ends of the third limiting plate. One end of each of the two limiting rods is fixedly installed with one side of the adjacent first limiting plate.

[0016] With the above technical solution, the third limiting plate can slide in the sliding groove of the third support plate. When the third limiting plate slides to a suitable position, the limiting rods at the bottoms of its two ends can limit the rotation angle of the first limiting plate, ensuring that the first limiting plate and the second limiting plate remain fixed when limiting the cable pipe, and preventing the first limiting plate and the second limiting plate from separating and opening during the cutting process.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: [[ID=第十二]]

[0018] By setting the rotatable first limiting plate and second limiting plate, and cooperating with components such as the moving column, rubber column, pushing plate, and threaded column, the present utility model realizes the rapid and accurate limiting and fixing of cable pipes with different thicknesses, solves the problems in the prior art that it is impossible to effectively limit cable pipes of any size and the speed of limiting and fixing is slow; at the same time, the setting of the lifting component and the third limiting plate further improves the versatility and stability of the limiting structure, ensuring that the cable pipe can be efficiently and accurately limited in the complex environment of the construction site, thereby improving the cutting quality and construction efficiency of the cable pipe.

[0024] Next, in combination with the accompanying drawings and the detailed implementation mode, the present utility model will be further described. It should be noted that on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 , A limiting structure of a cutting device for rigid polyvinyl chloride cable pipes in this embodiment includes a cutter main body 1. On both sides of the cutter main body 1, limiting components for limiting cable pipes of different thicknesses are symmetrically arranged. Below each limiting component, a lifting component capable of raising or lowering adjacent limiting components is provided.

[0026] The limiting component includes a first limiting plate 201 arranged on one side of the cutter main body 1. On one side of the first limiting plate 201, a second limiting plate 202 is rotatably installed. Both the first limiting plate 201 and the second limiting plate 202 are arranged in a semi-circular ring shape.

[0027] The semi-circular ring structure formed by the first limiting plate 201 and the second limiting plate 202 can be opened or closed by rotation according to the thickness of the cable pipe, realizing the preliminary adaptation and limitation of cable pipes of different pipe diameters. Compared with the traditional limiting structure, it can better adapt to cable pipes of various sizes.

[0028] Inside the ring formed by the first limiting plate 201 and the second limiting plate 202, a plurality of moving columns 4 arranged in a "C" shape are provided. Each moving column 4 is rotatably sleeved with a rubber column 5. Both ends of each moving column 4 penetrate through the adjacent first limiting plate 201 or second limiting plate 202. Outside the ring formed by the first limiting plate 201 and the second limiting plate 202, a plurality of push plates 6 are provided. Each push plate 6 is fixedly installed with both ends of the adjacent moving column 4.

[0029] When further fixing the cable pipe is needed, push the push plate 6. The push plate 6 drives the moving column 4 to move. The rubber column 5 on the moving column 4 moves accordingly and contacts the surface of the cable pipe. The rubber column 5 can not only increase the friction with the cable pipe to prevent the cable pipe from sliding back and forth during the cutting process, but also the rotatable sleeve design allows the cable pipe to rotate during the cutting process, adapting to more cable pipe cutting methods.

[0030] On one side of each pushing plate 6, there is a threaded column 7. One end of each threaded column 7 threadedly penetrates through the adjacent pushing plate 6 and is rotatably installed with a connecting block 8. Each connecting block 8 is fixedly installed with the adjacent first limiting plate 201 or second limiting plate 202. The other end of each threaded column 7 is fixedly installed with a rotating block 9, and a nut 10 is threadedly sleeved on each threaded column 7.

[0031] Rotate the rotating block 9, and the threaded column 7 will rotate accordingly. Since the threaded column 7 is threadedly connected to the pushing plate 6, the pushing plate 6 will move under the action of the threaded column 7, thereby precisely adjusting the extrusion force of the rubber column 5 on the cable pipe. After the adjustment is completed, tighten the nut 10 to fix the position of the pushing plate 6, ensuring that the limiting effect of the rubber column 5 on the cable pipe during the cutting process is stable and reliable, and achieving precise limiting and fixing of the cable pipe.

[0032] The bottom of the cutting machine main body 1 is fixedly installed with a first connecting plate 11. The lifting component includes a first support plate 301 fixedly installed at the top of one end of the first connecting plate 11. A second support plate 302 is slidably sleeved on the first support plate 301. The top of the second support plate 302 is fixedly installed with the adjacent second limiting plate 202. The first support plate 301 is provided with a plurality of first fixing holes penetrating through itself. The second support plate 302 is provided with a second fixing hole penetrating through itself. One side of the second support plate 302 is provided with a fixing plate 303 arranged in an "L" shape, and one side of the fixing plate 303 passes through the adjacent first fixing hole and second fixing hole.

[0033] After adjusting the height of the second support plate 302 on the first support plate 301, insert the fixing plate 303 into the corresponding first fixing hole and second fixing hole to fix the position of the second support plate 302, prevent the limiting component from moving up and down during the cutting process, ensure the stability of the limit, and thus ensure the smooth progress of the cutting work.

[0034] One side of the first connecting plate 11 is provided with a second connecting plate 12 fixedly installed with the bottom of the cutting machine main body 1. Both ends of the top of the second connecting plate 12 are fixedly installed with third support plates 13. One side of the top of the two third support plates 13 is provided with sliding grooves. A third limiting plate 14 arranged in a "C" shape is provided between the two third support plates 13. The third limiting plate 14 is slidably matched with the two third support plates 13 through the sliding grooves. Limiting rods 15 are provided at the bottoms of both ends of the third limiting plate 14, and one end of each of the two limiting rods 15 is fixedly installed with one side of the adjacent first limiting plate 201.

[0035] The third limiting plate 14 can slide within the sliding groove of the third support plate 13. When the third limiting plate 14 slides to the appropriate position, the limiting rods 15 at the bottom of both ends can limit the rotation angle of the first limiting plate 201, ensuring that the first limiting plate 201 and the second limiting plate 202 remain fixed when limiting the cable pipe, and preventing the first limiting plate 201 and the second limiting plate 202 from separating and opening during the cutting process.

[0036] The implementation principle of the limiting structure based on the rigid polyvinyl chloride cable pipe cutting device in this application embodiment is as follows: Before cutting the cable pipe, firstly, according to the placement height of the cable pipe, the fixing plate 303 is pulled out, the position of the second support plate 302 on the first support plate 301 is adjusted so that the height of the limiting component is adapted to the cable pipe, and after the adjustment is completed, the fixing plate 303 is inserted and fixed.

[0037] Then, remove the third limiting plate 14. At this time, the limiting rod 15 is no longer blocked by the third limiting plate 14, and the first limiting plate 201 and the second limiting plate 202 can be rotated open. Place the cable tube in the semi-circular ring structure formed by the first limiting plate 201 and the second limiting plate 202, and rotate the first limiting plate 201 and the second limiting plate 202 to make them initially fit the cable tube.

[0038] Next, rotate the rotating block 9 on the threaded column 7. The rotation of the threaded column 7 drives the push plate 6 to move. The push plate 6 pushes the moving column 4. The moving column 4 drives the rubber column 5 to move towards the cable pipe until the rubber column 5 is in close contact with the surface of the cable pipe. After adjusting the squeezing force, tighten the nut 10 to fix the position of the push plate 6, thereby achieving the limit fixation of the cable pipe.

[0039] The third limiting plate 14 is slidable so that it slides into the sliding groove to a suitable position to block the movement of the limiting rod 15. The limiting rod 15 restricts the rotation angle of the first limiting plate 201 to ensure the stability of the limiting.

[0040] At this point, the main body of the cutting machine 1 can be started to cut the cable pipe.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
