[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] This utility model provides a cable laying rack, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a bracket 1, a support rod 2, and a wire feeding roller 3.

[0025] The support rod 2 is connected to the bracket 1.

[0026] The wire feeding roller 3 includes two spacers 31, a connecting rod 32, a locking member 33, and a compression spring 34. Both spacers 31 are sleeved on the support rod 2. The connecting rod 32 passes through the spacers 31 along the axial direction of the spacers 31. The compression spring 34 is sleeved on the support rod 2 and is located between the two spacers 31. The two ends of the compression spring 34 abut against the two spacers 31 respectively. The compression spring 34 causes the two spacers 31 to tend to move away from each other. The two locking members 33 are connected to the connecting rod 32 at any position and abut against the side of the spacers 31 that is away from each other, so that the distance between the spacers 31 can be adjusted.

[0027] In use, both spacers 31 are fitted onto the support rod 2, and the compression spring 34 is also fitted onto the support rod 2 and positioned between the two spacers 31, with its ends abutting against the two spacers 31 respectively. The elastic force of the compression spring 34 causes the two spacers 31 to tend to move away from each other, which is the basis for the wire feed roller 3 to adapt to cable coils of different widths. When the locking member 33 moves closer to the spacers 31, it squeezes the spacers 31, overcoming the elastic force of the compression spring 34, thus reducing the distance between the two spacers 31; conversely, when the locking member 33 moves away from the spacers 31, the distance between the two spacers 31 increases under the action of the elastic force of the compression spring 34. Therefore, the distance between the two spacers 31 can be changed by adjusting the position of the locking member 33 according to the actual width of the cable coil, thereby adapting to cable coils of different widths.

[0028] In this invention, by adjusting the spacing of the partitions 31, it can accommodate cable coils of different widths. Whether it is a narrow communication cable coil or a wide power cable coil, it can be stably placed and used for cable laying operations, which greatly improves the versatility of the cable laying frame, reduces the trouble of having to change different cable laying frames due to different cable coil widths, and lowers costs.

[0029] To prevent the feed roller 3 from sliding on the support rod 2 during the feed process, please refer to... Figure 1 In a preferred embodiment, the wire feeding frame further includes an elastic ring 35, which is sleeved on the support rod 2, located between adjacent wire feeding rollers 3, and abuts against the wire feeding rollers 3.

[0030] During use, the elastic ring 35 abuts against the pay-off roller 3, providing positioning and limiting functions. When the pay-off roller 3 rotates on the support rod 2, the elastic ring 35, through its own contact friction with the pay-off roller 3, can limit unnecessary axial displacement of the pay-off roller 3 on the support rod 2, ensuring that the pay-off roller 3 is always in a suitable working position. Especially when multiple pay-off rollers 3 work together, the elastic ring 35 can ensure the relative position stability between adjacent pay-off rollers 3, avoiding mutual interference during cable pay-off caused by positional deviation of the pay-off rollers 3, and enabling the cable to be paid off from the pay-off rollers 3 in an orderly and smooth manner.

[0031] To improve the ease of installation of link 32, please refer to... Figure 2 In a preferred embodiment, the wire feeding frame further includes a plurality of strip holes 36, which are arranged around the partition plate 31 and extend radially along the partition plate 31. A plurality of connecting rods 32 are provided, and the plurality of connecting rods 32 are slidably connected to the plurality of strip holes 36 respectively.

[0032] During use, when installing the pay-off roller 3, multiple connecting rods 32 can be initially connected and positioned with the spacer 31 through the slotted holes 36. Installers can easily insert the connecting rods 32 into the slotted holes 36 before installing and adjusting other components. This makes the assembly process of the pay-off frame simpler and faster, reduces installation difficulty, and improves work efficiency.

[0033] To improve the strength at the strip hole 36 on the partition plate 31, please refer to... Figure 2 In a preferred embodiment, the wire feeding frame further includes a plurality of reinforcing ribs 37, which are arranged around the partition plate 31 and extend radially along the partition plate 31. The plurality of strip holes 36 are respectively located at the plurality of reinforcing ribs 37.

[0034] In use, multiple slotted holes 36 are located at multiple reinforcing ribs 37, which provide additional support and reinforcement for the slotted holes 36. When the connecting rod 32 slides within the slotted holes 36, the reinforcing ribs 37 ensure the shape and dimensional stability of the slotted holes 36, preventing deformation or damage caused by friction from the connecting rod 32 or the force of the cable. This ensures the smooth sliding connection between the connecting rod 32 and the slotted holes 36, allowing the adjustment function of the partition 31 to be realized smoothly and improving the adaptability of the cable feeder to cable coils of different widths.

[0035] To lock partition 31, please refer to... Figure 2 In a preferred embodiment, the locking element 33 is a nut, which is threaded onto the connecting rod 32 and abuts against the side of the spacer 31 away from the compression spring 34.

[0036] In use, when it is necessary to lock the spacer 31, the nut is rotated, causing it to move on the connecting rod 32. When the nut is rotated to the appropriate position, it will tightly abut against the spacer 31 on the side away from the compression spring 34. At this time, the nut exerts pressure on the compression spring 34 through the spacer 31, compressing the spring 34 and generating a reaction force. This reaction force is transmitted to the nut through the spacer 31, resulting in a large frictional force between the nut and the spacer 31, thereby preventing the nut from continuing to rotate and move, thus locking the spacer 31.

[0037] To guide the cable laying direction, please refer to... Figure 2 In a preferred embodiment, the wire feeding frame further includes a frame 4 and a plurality of guide rings 41. The frame 4 is connected to the support 1, and the plurality of guide rings 41 are sequentially and spaced apart on the frame 4 along the axial direction of the spacer 31. The guide rings 41 correspond one-to-one with the wire feeding rollers 3, and the guide rings 41 allow the cable to pass through.

[0038] In use, frame 4 is connected to bracket 1, providing a mounting base for guide rings 41. Multiple guide rings 41 are sequentially and spaced apart along the axial direction of spacer 31 on frame 4, corresponding one-to-one with feed roller 3. When the cable is released from feed roller 3, it passes through the corresponding guide ring 41. The guide rings 41 guide the cable's direction, ensuring it is released along a predetermined path and direction, preventing random swinging or tangling during the release process, and guaranteeing the orderly delivery of the cable to the subsequent construction or usage location.

[0039] To accommodate cable laying operations at different heights, please refer to... Figure 2 In a preferred embodiment, the wire feeding frame further includes a fixing component 42, the frame 4 is rotatably connected to the bracket 1 to adjust the height of the guide ring 41, and the fixing component 42 is used to fix the frame 4.

[0040] During use, when the height of the guide ring 41 needs to be adjusted, the operator can manually or through other driving devices rotate the frame 4 around the rotating connection point. Since the guide ring 41 is connected to the frame 4, the rotation of the frame 4 will drive the guide ring 41 to move together, thereby changing the height of the guide ring 41. The height of the guide ring 41 can be flexibly adjusted according to different cable laying requirements to adapt to cable laying operations at different heights or to better connect with other equipment. The function of the fixing component 42 is to fix the frame 4 in place after it has rotated to the appropriate position, preventing it from rotating freely.

[0041] To secure frame 4, please refer to... Figure 2 In a preferred embodiment, the fixing component 42 includes a plug rod 421, the frame 4 is provided with a plug hole 422, and the bracket 1 is provided with a plurality of slots 423 spaced apart along the rotation direction of the frame 4, and the plug rod 421 passes through the plug hole 422 and any slot 423.

[0042] In use, when the height of the guide ring 41 needs to be adjusted, the operator manually rotates the frame 4. Due to the rotating connection structure between the frame 4 and the bracket 1, the frame 4 can rotate smoothly around the connection point, causing the guide ring 41 connected to the frame 4 to change its height to adapt to different cable laying requirements. The frame 4 is provided with insertion holes 422, while the bracket 1 has multiple slots 423 spaced apart along the rotation direction of the frame 4. When the frame 4 rotates to the appropriate height position, the insertion holes 422 will align with the corresponding slots 423 on the bracket 1. At this time, the insertion rod 421 is inserted into the insertion hole 422, passing through the insertion hole 422 and entering the corresponding slot 423. The frame 4 is then securely fixed in its current position, ensuring that the height of the guide ring 41 remains stable.

[0043] To make it easier for the insert 421 to slide into the slot 423, please refer to... Figure 2 In a preferred embodiment, the end of the insertion rod 421 near the bracket 1 is spherical.

[0044] In use, the spherical end slides more smoothly into the slot 423 of the bracket 1 compared to a regular flat or sharp end. When the insert 421 needs to be inserted into the slot 423 to fix the frame 4, the spherical end can more easily align with the opening of the slot 423, reducing resistance and jamming during insertion, reducing the difficulty of operation for the operator, and improving the efficiency of fixing the frame 4.

[0045] To improve the stability of the insertion rod 421, please refer to... Figure 2In a preferred embodiment, the fixing component 42 further includes a tension spring, which is sleeved on the insertion rod 421. One end of the tension spring is connected to the insertion rod 421, and the other end of the tension spring is connected to the frame 4. The tension spring is in a stretched state, and the tension spring causes the insertion rod 421 to tend to slide towards the bracket 1.

[0046] In use, a tension spring is fitted onto the insertion rod 421, with one end connected to the insertion rod 421 and the other end connected to the frame 4, and is in a stretched state. The spring force directs the insertion rod 421 towards the bracket 1, and this force continuously acts on the insertion rod 421, providing a stable tension towards the bracket 1. Because the tension spring causes the insertion rod 421 to tend to slide towards the bracket 1, when the insertion rod 421 is inserted into the insertion hole 422 of the frame 4 and the slot 423 of the bracket 1, the spring force will cause the insertion rod 421 to be tightly inserted into the slot 423, increasing the friction between the insertion rod 421 and the slot 423 and the tightness of the connection. This prevents the insertion rod 421 from accidentally coming out of the slot 423 without external force, ensuring a stable connection between the frame 4 and the bracket 1.

[0047] To better understand this utility model, the following is combined with... Figure 1 - Figure 2 The working principle of a cable feeding frame according to the present invention is described in detail below: Two spacers 31 are both sleeved on the support rod 2, and a compression spring 34 is also sleeved on the support rod 2 and located between the two spacers 31, with its two ends abutting against the two spacers 31 respectively. The elastic force of the compression spring 34 causes the two spacers 31 to tend to move away from each other, which is the basis for the feeding roller 3 to adapt to cable coils of different widths. When the locking member 33 moves closer to the spacers 31, the locking member 33 will squeeze the spacers 31, overcoming the elastic force of the compression spring 34, and reducing the distance between the two spacers 31; conversely, when the locking member 33 moves away from the spacers 31, the distance between the two spacers 31 will increase under the action of the elastic force of the compression spring 34. Therefore, the distance between the two spacers 31 can be changed by adjusting the position of the locking member 33 according to the actual width of the cable coil, thereby adapting to cable coils of different widths.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
