[0003] In practical use, the above solution requires unscrewing the four sets of limiting plates, manually winding the optical cable, adjusting the four sets of screws to fix it, and then fixing the four sets of limiting plates again. The steps are relatively cumbersome and laborious. Therefore, this application provides a drop cable pre-reservation device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a drop cable pre-reservation device, which overcomes the shortcomings of the prior art and aims to solve the problem that in actual use, the above solutions require unscrewing the four sets of limiting plates, manually winding the optical cable, adjusting the four sets of screws to fix it, and then fixing the four sets of limiting plates again, which is a relatively cumbersome and laborious process.

[0005] To achieve the above objectives, this application provides the following technical solution: a drop cable pre-reservation device, comprising a pre-reservation box, an inlet hole on one side of the pre-reservation box, a winding mechanism inside the pre-reservation box, the winding mechanism comprising a rotating seat, the rotating seat being fixedly installed inside the pre-reservation box, a rotating shaft being rotatably connected to the top of the rotating seat, a circular plate being fixedly installed on the top of the rotating shaft, a clamping box being fixedly installed through the circular plate at the top of the rotating shaft, a clamping mechanism being provided inside the clamping box, a central shaft being fixedly installed at the top of the clamping box, a rotating handle being fixedly installed at the top of the central shaft, and a plurality of winding rollers being fixedly installed at the top of the circular plate, the plurality of winding rollers being arranged in a circumferential shape around the central shaft.

[0006] By adopting the above technical solution, one end of the optical cable enters the reserved box through the inlet hole. The clamping mechanism fixes one end of the optical cable inside the clamping box. Then, the rotating handle is turned, which drives the central shaft and the rotating shaft to rotate. The central shaft drives several sets of winding rollers to rotate, so that the optical cable is wound on the outer surface of several sets of winding rollers, realizing the reservation of the optical cable. By turning the rotating handle, the optical cable can be quickly wound on several sets of winding rollers. The operation is simple and improves the convenience and efficiency of use.

[0007] As a preferred technical solution of this application, the clamping mechanism includes two sets of springs, both sets of springs are installed inside the clamping box, a lower clamping block is installed at the top of the spring, an upper clamping block is fixedly installed inside the clamping box directly above the two sets of lower clamping blocks, and a connecting rod is installed between the two sets of lower clamping blocks.

[0008] By adopting the above technical solution, the optical cable is fixed between the two sets of lower clamping blocks and upper clamping blocks by utilizing the elastic force of two sets of springs, thereby achieving the purpose of clamping and fixing the optical cable and ensuring the stability of the optical cable during the reservation process.

[0009] As a preferred technical solution of this application, the top of the reserved box is slidably connected with two sets of cover plates. The opposite surfaces of the two sets of cover plates are provided with semi-circular slots that match the rotating handle. A fixing seat is fixedly installed on the top of one set of cover plates, and a vertical plate is fixedly installed on the top of the other set of cover plates. A screw is inserted into the inside of the vertical plate, and a through hole is opened inside the rotating handle. The screw passes through the through hole and is threadedly connected to the fixing seat.

[0010] By adopting the above technical solution, the two sets of cover plates are slidably connected to the reserved box, which facilitates the operation of the components inside the reserved box. The rotating handle is fixed between the upright plate and the fixed base by the screw, and the position of the rotating handle after adjustment is locked to ensure that the wound optical cable will not be accidentally loosened. The two sets of cover plates are also fixed to the top of the reserved box, which improves the protection effect inside the reserved box.

[0011] As a preferred technical solution of this application, a set of lower clamping blocks are fixedly installed on one end of the connecting rod.

[0012] By adopting the above technical solution, the position of the two sets of lower clamping blocks can be adjusted simultaneously by pressing down the pressing plate, which facilitates the placement of one end of the optical cable. Releasing the pressing plate allows the two sets of lower clamping blocks to automatically push the optical cable upward under the elastic action of the two sets of springs, so as to achieve the purpose of clamping and fixing one end of the optical cable together with the two sets of lower clamping blocks and the upper clamping block.

[0013] As a preferred technical solution of this application, anti-slip pads are fixedly installed on the opposite surfaces of the two sets of lower clamping blocks and the upper clamping blocks, and the anti-slip pads are made of rubber.

[0014] By adopting the above technical solution, the anti-slip pad not only increases the friction between the lower and upper clamping blocks when clamping the optical cable, but also avoids damage to the outer wall of the optical cable caused by the spring and the lower clamping block, thereby improving the stability of the optical cable and the protection effect of the optical cable.

[0015] As a preferred technical solution of this application, the bottom of the reserved box is fixedly installed with a guide rail below the circular plate, and the sliding end of the guide rail is slidably connected with two sets of guide blocks, the top end of the guide blocks being fixedly installed at the bottom end of the circular plate.

[0016] By adopting the above technical solution, the circular plate drives two sets of guide blocks to slide at the sliding end of the guide rail when rotating, which guides the circular plate when it rotates and also provides support for the circular plate.

[0017] As a preferred technical solution of this application, a soft sleeve is fixedly installed on the top of the rotating handle.

[0018] By adopting the above technical solution, the soft sleeve makes contact with the operator's hand when rotating the handle, which helps to increase hand comfort.

[0019] As a preferred technical solution of this application, the spring is provided with a telescopic guide rod inside.

[0020] By adopting the above technical solution, the spring's elastic extension and contraction is guided by the telescopic guide rod, which helps to extend the spring's service life.

[0021] The beneficial effects of this application are:

[0022] 1. One end of the optical cable enters the reserved box through the inlet hole. The clamping mechanism fixes one end of the optical cable inside the clamping box. Then, the rotating handle is turned, which drives the central shaft and the rotating shaft to rotate. The central shaft drives several sets of winding rollers to rotate, so that the optical cable is wound on the outer surface of several sets of winding rollers, realizing the reservation of the optical cable. By turning the rotating handle, the optical cable can be quickly wound on several sets of winding rollers. The operation is simple and improves the convenience and efficiency of use.

[0023] 2.

[0030] Reference Figure 1-4 A fiber optic cable pre-installation device includes a pre-installation box 1. An inlet 2 is provided on one side of the pre-installation box 1. A winding mechanism 4 is installed inside the pre-installation box 1. The winding mechanism 4 includes a rotating seat 401, which is fixedly installed inside the pre-installation box 1. A rotating shaft 402 is rotatably connected to the top of the rotating seat 401. A circular plate 403 is fixedly installed on the top of the rotating shaft 402. A clamping box 404 is fixedly installed through the circular plate 403 at the top of the rotating shaft 402. A clamping mechanism 5 is provided inside the clamping box 404. A central shaft 405 is fixedly installed at the top of the clamping box 404. A rotating handle 407 is fixedly installed. Several sets of winding rollers 406 are fixedly installed on the top of the circular plate 403. The sets of winding rollers 406 are arranged in a circumferential shape with the central axis 405 as the center. Two sets of cover plates 3 are slidably connected to the top of the reserved box 1. The opposite surfaces of the two sets of cover plates 3 are provided with semi-circular slots 6 that match the rotating handle 407. A fixed seat 9 is fixedly installed on the top of one set of cover plates 3. A vertical plate 10 is fixedly installed on the top of the other set of cover plates 3. A screw 12 is inserted into the inside of the vertical plate 10. A through hole 11 is opened inside the rotating handle 407. The screw 12 passes through the through hole 11 and is threadedly connected to the fixed seat 9.

[0031] One end of the optical cable enters the pre-reservation box 1 through the inlet 2. The clamping mechanism 5 fixes one end of the optical cable inside the clamping box 404. Then, the rotating handle 407 is rotated, which drives the central shaft 405 and the rotating shaft 402 to rotate. The central shaft 405 drives several sets of winding rollers 406 to rotate, so that the optical cable is wound on the outer surface of the winding rollers 406, realizing the pre-reservation of the optical cable. By rotating the rotating handle 407, the optical cable can be quickly wound on the winding rollers 406. The operation is simple and improves the convenience and efficiency of use. The two sets of cover plates 3 are slidably connected to the pre-reservation box 1, which facilitates the operation of the components inside the pre-reservation box 1. The rotating handle 407 is fixed between the upright plate 10 and the fixed seat 9 by the screw 12. The position of the rotating handle 407 after adjustment is locked to ensure that the wound optical cable will not be accidentally loosened. The two sets of cover plates 3 are fixed to the top of the pre-reservation box 1 to improve the protection effect inside the pre-reservation box 1.

[0032] Reference Figure 1-3 The clamping mechanism 5 includes two sets of springs 501, both sets of springs 501 are installed inside the clamping box 404, and a lower clamping block 502 is installed on the top of the spring 501. An upper clamping block 503 is fixedly installed inside the clamping box 404 directly above the two sets of lower clamping blocks 502. A connecting rod 504 is installed between the two sets of lower clamping blocks 502. A pressing plate 7 is fixedly installed through one set of lower clamping blocks 502 at one end of the connecting rod 504.

[0033] By utilizing the elastic force of two sets of springs 501, the optical cable is fixed between two sets of lower clamping blocks 502 and upper clamping blocks 503, thereby achieving the purpose of clamping and fixing the optical cable and ensuring its stability during the pre-installation process. By pressing down the button 7, the position of the two sets of lower clamping blocks 502 can be adjusted downwards simultaneously, facilitating the placement of one end of the optical cable. Releasing the button 7 allows the two sets of lower clamping blocks 502 to automatically push the optical cable upwards under the elastic action of the two sets of springs 501, achieving the purpose of clamping and fixing one end of the optical cable together with the two sets of lower clamping blocks 502 and upper clamping blocks 503.

[0034] Reference Figure 2-4 Anti-slip pads 8, made of rubber, are fixedly installed on the opposite surfaces of the two sets of lower clamping blocks 502 and upper clamping blocks 503. A soft sleeve 13 is fixedly installed on the top of the rotating handle 407. The anti-slip pads 8 not only increase the friction between the lower clamping blocks 502 and upper clamping blocks 503 when clamping the optical cable, but also prevent the spring 501 and lower clamping blocks 502 from damaging the outer wall of the optical cable, thus improving the stability of the optical cable and the protection effect of the optical cable. When the operator rotates the rotating handle 407, the soft sleeve 13 comes into contact with the operator's hand, which helps to increase the comfort of the hand.

[0035] Reference Figure 1-3The bottom of the reserved box 1 is fixedly installed below the circular plate 403 with a guide rail 15. The sliding end of the guide rail 15 is slidably connected to two sets of guide blocks 14. The top of the guide blocks 14 is fixedly installed at the bottom end of the circular plate 403. The spring 501 is provided with a telescopic guide rod 16. When the circular plate 403 rotates, it drives the two sets of guide blocks 14 to slide at the sliding end of the guide rail 15, which guides the circular plate 403 when it rotates and can also support the circular plate 403. The telescopic guide rod 16 guides the spring 501 during the elastic extension and contraction process, which helps to extend the service life of the spring 501.

[0036] Working principle: One end of the optical cable enters the pre-reservation box 1 through the inlet 2. The clamping mechanism 5 fixes one end of the optical cable inside the clamping box 404. Then, the rotating handle 407 is rotated, which drives the central shaft 405 and the rotating shaft 402 to rotate. The central shaft 405 drives several sets of winding rollers 406 to rotate, so that the optical cable is wound on the outer surface of the winding rollers 406, realizing the pre-reservation of the optical cable. By rotating the rotating handle 407, the optical cable can be quickly wound on the winding rollers 406. The operation is simple and improves the convenience and efficiency of use. The elastic force of two sets of springs 501 is used to fix the optical cable between two sets of lower clamping blocks 502 and upper clamping blocks 503, so as to achieve the purpose of clamping and fixing the optical cable and ensuring the stability of the optical cable during the pre-reservation process.

[0037] The two sets of cover plates 3 are slidably connected to the reserved box 1, which facilitates the operation of the components inside the reserved box 1. The rotating handle 407 is fixed between the upright plate 10 and the fixed seat 9 by the screw 12. The position of the rotating handle 407 after adjustment is locked to ensure that the wound optical cable will not be accidentally loosened. The two sets of cover plates 3 are fixed to the top of the reserved box 1 to improve the protection effect inside the reserved box 1. The position of the two sets of lower clamping blocks 502 can be adjusted by pressing down the button 7, which facilitates the placement of one end of the optical cable. The button 7 is released so that the two sets of lower clamping blocks 502 can automatically push the optical cable upward under the elastic action of the two sets of springs 501, so that the two sets of lower clamping blocks 502 and the upper clamping block 503 can clamp and fix one end of the optical cable together.

[0038] Meanwhile, the anti-slip pad 8 not only increases the friction between the lower clamping block 502 and the upper clamping block 503 when clamping the optical cable, but also prevents the spring 501 and the lower clamping block 502 from damaging the outer wall of the optical cable, thus improving the stability of the optical cable and the protection effect of the optical cable; when the circular plate 403 rotates, it drives the two sets of guide blocks 14 to slide at the sliding end of the guide rail 15, which plays a guiding role when the circular plate 403 rotates, and can also provide support for the circular plate 403.

[0039] In addition, the soft sleeve 13 makes contact with the operator's hand when rotating the handle 407, which helps to increase hand comfort; the telescopic guide rod 16 guides the elastic extension and contraction of the spring 501, which helps to extend the service life of the spring 501.
