Cable sheaths come in various types, including PVC split tubing, which can also be used for cable protection.

[0003] When PVC split pipes are processed into protective sleeves, a limiting device is needed to limit their movement so that workers can process them. However, traditional limiting devices often do not have a good fixing effect, and the PVC split pipes can still move during processing, thereby reducing the processing quality. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a limiting mechanism for processing flame-retardant cable protective sleeves. This mechanism can provide double limiting for PVC half tubes, effectively improving the limiting effect and preventing the PVC half tubes from shaking during processing, which would lead to poor processing quality. It also solves the problem that traditional limiting devices often have insufficient fixing effect and are not stable enough during processing, which would reduce processing quality.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a C-shaped frame 1, a placement block 2 fixedly connected to the right side of the C-shaped frame 1, a placement groove 3 opened on the top of the placement block 2, a support leg 4 fixedly connected to the bottom of the placement block 2, a clamping mechanism 5 provided on the inner side of the C-shaped frame 1, and a fixing mechanism 6 provided on the top of the placement block 2. Clamping mechanism 5 is used to limit the PVC split pipe from both the front and rear sides; The fixing mechanism 6 is used in conjunction with the placement block 2 to limit the PVC split pipe from the top and bottom, further improving the limiting effect.

[0022] Specifically, it achieves double limiting of PVC split pipes, effectively improving the limiting effect and preventing the PVC split pipes from shaking during processing, which would lead to poor processing quality.

[0023] Furthermore, by setting the handwheel 501 to drive the bidirectional screw 502 to rotate, the two clamping blocks 504 clamp the front and rear sides of the PVC half pipe. By driving the screw 602 to rotate through the knob 601, the pressure block 603 cooperates with the placement block 2 to limit the PVC half pipe in the vertical direction.

[0024] An anti-slip pad 13 is fixedly connected to the inner wall of the placement groove 3. When the PVC split tube is placed in the placement groove 3, the anti-slip pad 13 increases the friction between the PVC split tube and the placement groove 3, preventing the PVC split tube from sliding within the placement groove 3. This enhances the stability of the PVC split tube during placement.

[0025] Example 2 The second embodiment of this utility model provides a clamping mechanism 5 including a handwheel 501. A bidirectional lead screw 502 is fixedly connected to the rear side of the handwheel 501. The rear end of the bidirectional lead screw 502 extends through to the inner side of the C-shaped frame 1 and is rotatably connected to the inner side of the C-shaped frame 1 through a bearing. The surface of the bidirectional lead screw 502 is rotatably connected to the inner wall of the C-shaped frame 1 through a bearing. A transmission block 503 is drively connected to the surface of the bidirectional lead screw 502. A clamping block 504 is fixedly connected to the right side of the transmission block 503.

[0026] Specifically, by operating the handwheel 501, workers can easily limit the movement of the PVC split pipe, thus initially preventing the PVC split pipe from moving during processing.

[0027] Furthermore, by rotating the handwheel 501, the bidirectional lead screw 502 is driven to rotate. The bidirectional lead screw 502 is connected to the transmission block 503, which causes the two transmission blocks 503 to move relative to each other along the bidirectional lead screw 502, thereby driving the clamping block 504 to move. The clamping block 504 clamps the front and rear sides of the PVC half pipe through the protective pad 12.

[0028] Example 3 The third embodiment of this utility model provides a fixing mechanism 6 including a knob 601, a screw 602 fixedly connected to the bottom of the knob 601, a pressure block 603 rotatably connected to the bottom of the screw 602 through a bearing, and a movable frame 604 drivingly connected to the surface of the screw 602.

[0029] Specifically, it is simple and convenient to operate, and can quickly fix the PVC split pipe in the vertical direction, further enhancing the limiting effect and preventing the PVC split pipe from warping during processing.

[0030] Furthermore, rotating the knob 601 drives the screw 602 to rotate. The screw 602 is connected to the movable frame 604. Under the action of the movable frame 604, the screw 602 will drive the pressure block 603 to move up and down. When the pressure block 603 moves down, the pressure block 603 cooperates with the placement block 2 through the protective pad 12 to limit the PVC half pipe in the up and down direction.

[0031] Square plates 7 are fixedly connected to both the front and rear sides of the placement block 2. Limiting grooves 8 are formed on the inner walls of the square plates 7, and limiting blocks 9 are slidably connected to the inner walls of the limiting grooves 8. The top of the limiting blocks 9 extends above the limiting slots and is fixedly connected to the movable frame 604. When the movable frame 604 moves left and right, it drives the limiting blocks 9 to slide within the limiting grooves 8. The cooperation between the limiting grooves 8 and the limiting blocks 9 allows the fixing mechanism 6 to move stably left and right. By allowing the fixing mechanism 6 to move, the fixing position can be easily adjusted as needed, and the farther the fixing position of the fixing mechanism 6 is from the fixing position of the clamping mechanism 5, the better its limiting effect.

[0032] A first round rod 10 is slidably connected to the inner wall of the transmission block 503. Both ends of the first round rod 10 are fixedly connected to the inner side of the C-shaped frame 1. A second round rod 11 is fixedly connected to the top of the pressure block 603. The top end of the second round rod 11 extends above the movable frame 604, and the surface of the second round rod 11 is slidably connected to the inner wall of the movable frame 604. The first round rod 10 prevents the transmission block 503 from rotating with the bidirectional screw 502, thereby affecting the clamping effect; the second round rod 11 prevents the pressure block 603 from shifting with the rotation of the screw 602, ensuring that the pressure block 603 can accurately limit the PVC half pipe through the protective pad 12.

[0033] Protective pads 12 are fixedly connected to one side of clamping block 504 and the bottom of pressure block 603. When clamping block 504 and pressure block 603 come into contact with PVC split pipe, the protective pads 12 directly contact the surface of PVC split pipe, which can increase the friction of the contact area and prevent clamping block 504 and pressure block 603 from scratching or damaging the surface of PVC split pipe, thus preventing damage to PVC split pipe and improving product qualification rate.

[0034] Working principle: Place the PVC split pipe on the anti-slip pad 13 in the placement groove 3, and make its left end abut against the right side of the C-shaped frame 1. Then, turn the handwheel 501 to drive the double-acting screw 502 to rotate. The double-acting screw 502 is connected to the transmission block 503, which will cause the two transmission blocks 503 to move relative to each other along the double-acting screw 502, thereby driving the clamping block 504 to move. The clamping block 504 clamps the front and rear sides of the PVC split pipe through the protective pad 12. By operating the handwheel 501, the operator can easily limit the PVC half pipe, initially preventing it from moving during processing. Then, according to the needs, the movable frame 604 is pushed to bring the fixing mechanism 6 to the appropriate position. The knob 601 is turned to drive the screw 602 to rotate. The screw 602 is connected to the movable frame 604. Under the action of the movable frame 604, the screw 602 will drive the pressure block 603 to move up and down. When the pressure block 603 moves downward, it limits the PVC half pipe in the vertical direction through the protective pad 12 and the placement block 2. The operation is simple and convenient, and it can quickly fix the PVC half tube in the vertical direction, further enhancing the limiting effect and preventing the PVC half tube from tilting during processing. The farther the fixed position of the fixing mechanism 6 is from the fixed position of the clamping mechanism 5, the better the limiting effect. The first round rod 10 prevents the transmission block 503 from rotating with the bidirectional screw 502, thus affecting the clamping effect. The second round rod 11 prevents the pressure block 603 from shifting with the rotation of the screw 602, ensuring that the pressure block 603 can accurately limit the PVC half tube through the protective pad 12. The protective pad 12 is in direct contact with the surface of the PVC half tube, which can increase the friction of the contact area and prevent the clamping block 504 and the pressure block 603 from scratching or damaging the surface of the PVC half tube, thus preventing damage to the PVC half tube and improving the product qualification rate.

[0035] In summary, the combination of clamping and fixing mechanisms enables double limiting of PVC split pipes, effectively improving the limiting effect and preventing poor processing quality caused by shaking of the PVC split pipes during processing.
