Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a cable fixing device. Background Art

[0002] With the continuous development of technology, various electronic devices, electrical devices, etc. have been widely used in people's lives. During the use of these devices, a large number of cables are often required for signal transmission and power supply. To ensure the normal operation of the cables, effective fixing and protection of the cables are needed.

[0003] When the traditional cable fixing device fixes the cable, the fixing method is relatively simple, the firmness of the cable is poor, and the cable will become loose after a long time. Moreover, the traditional fixing device is not easy to disassemble and has poor practicability. Summary of the Utility Model

[0004] Aiming at the above-mentioned shortcomings or deficiencies of the prior art, the utility model provides a cable fixing device that can clamp the cable twice, limit the clamping ring to improve the fixing effect, and is easy to disassemble at the same time.

[0005] A cable fixing device includes an installation base, a fixing ring is fixedly connected to the installation base, two through holes are opened on the fixing ring, a fixing rubber pad is fixedly connected to the fixing ring, a movable ring is placed on the fixing ring, two round holes are opened on both the fixing ring and the movable ring, a fastening bolt is placed between the two round holes on the same side, there are two fastening bolts in total, nuts are threadedly connected to the two fastening bolts, both nuts are in contact with the fixing ring, and a secondary clamping component is provided on the movable ring.

[0006] Further explanation, the secondary clamping component includes a screw rod, the screw rod is threadedly connected to the movable ring, the bottom of the screw rod is rotatably connected to a clamping ring, the clamping ring is slidably connected to the fixing ring, and a movable rubber pad is fixedly connected to the clamping ring.

[0007] Further explanation, it also includes rotating support plates, four rotating support plates are fixedly connected to the installation base, two rotating support plates are in a group, the two groups of installation bases are symmetrically arranged, a column gear is rotatably connected between the two rotating support plates in each group, and a ratchet wheel is fixedly connected to each of the two column gears.

[0008] Further explanation, it also includes a clamping rod, the clamping rod is rotatably connected to two rotating support plates close to the ratchet wheel, a reed is fixedly connected to the two rotating support plates close to the ratchet wheel, the reed and the clamping rod on the same side are in a group, and the reed in the same group is in contact with the top of the clamping rod.

[0009] Further explanation: It also includes a toothed rod. The two sides of the clamping ring are fixedly connected to the toothed rod, and each toothed rod extends into the perforations formed in the lower fixing ring.

[0010] The beneficial effects of the present utility model are as follows: 1. When the staff rotates the screw rod, the screw rod rotates and moves downward, driving the clamping ring to move downward to clamp the cable again. When it is necessary to remove the cable, the staff only needs to rotate the screw rod in the reverse direction and then rotate the fastening bolt in the reverse direction, and the cable is no longer limited, thus facilitating disassembly. In this way, after the cable is clamped by the fixing ring and the movable ring, and then the cable is secondarily clamped by the downward movement of the clamping ring, the fixing effect on the cable can be improved.

[0011] 2. During the downward movement of the movable ring and the clamping ring, the clamping ring will drive the toothed rod to descend. The toothed rod descends through the perforations formed in the fixing ring, and the toothed rod will engage with the column gear. The toothed rod drives the column gear to rotate, and the column gear drives the ratchet to rotate. The rotation of the ratchet will squeeze the latch, and the latch will swing upward under the extrusion. The upward swing of the latch will squeeze the reed, and the reed will deform under the extrusion. When the ratchet no longer squeezes the latch, the reed resets and drives the latch to re-lock the ratchet. In this way, the ratchet cannot reverse, and the non-reversal of the ratchet makes the column gear unable to rotate. The non-rotation of the column gear limits the toothed rod, thus realizing the limitation of the clamping ring and preventing the clamping ring from loosening. Description of the Drawings

Detailed Description of the Invention

[0018] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and explanations of this utility model are used to explain the present utility model, but do not limit the present utility model.

[0019] Embodiment 1: A cable fixing device, as Figures 1 - 5 shown, includes an installation base 1. A fixing ring 2 is fixedly connected to the installation base 1. Two through holes are opened on the fixing ring 2. A fixing rubber pad 3 is fixedly connected to the fixing ring 2. The fixing rubber pad 3 is used to prevent the device from scratching the surface of the cable. A movable ring 4 is placed on the fixing ring 2. Two round holes are opened on both the fixing ring 2 and the movable ring 4. A fastening bolt 5 is placed between the two round holes on the same side. There are two fastening bolts 5 in total. Nuts 6 are threadedly connected to the two fastening bolts 5. By tightening the nuts 6, the fixing ring 2 and the movable ring 4 can be closed. Both of the two nuts 6 are in contact with the fixing ring 2. A secondary clamping component is provided on the movable ring 4.

[0020] The secondary clamping component includes a screw rod 7. The screw rod 7 is threadedly connected to the movable ring 4. The bottom of the screw rod 7 is rotatably connected to a clamping ring 8. The clamping ring 8 is slidably connected to the fixing ring 2. A movable rubber pad 9 is fixedly connected to the clamping ring 8.

[0021] At first, the staff first places the cable to be fixed between the fixing ring 2 and the movable ring 4. Then the staff tightens the fastening bolts 5 and the nuts 6. Under the action of the fastening bolts 5 and the nuts 6, the movable ring 4 moves towards the fixing ring 2. The movable ring 4 and the fixing ring 2 clamp the cable. Then the staff rotates the screw rod 7 again. The screw rod 7 rotates and moves downward. The screw rod 7 drives the clamping ring 8 to move downward to clamp the cable again. In this way, after the cable is clamped by the fixing ring 2 and the movable ring 4, the cable is clamped again by the downward movement of the clamping ring 8. When the cable needs to be removed, the staff only needs to rotate the screw rod 7 in the reverse direction. The screw rod 7 drives the clamping ring 8 to rise. Then the staff rotates the fastening bolts 5 in the reverse direction. The movable ring 4 moves away from the fixing ring 2. The cable is no longer limited. The staff can remove the cable, so it is convenient to disassemble. In this way, by clamping the cable again by the downward movement of the clamping ring 8, the fixing effect on the cable can be improved.

[0022] Embodiment 2: On the basis of Embodiment 1, as Figures 4 - 5 shown, it further includes a rotating support plate 10. Four rotating support plates 10 are fixedly connected to the installation base 1. Two rotating support plates 10 are in a group. Two groups of installation bases 1 are symmetrically arranged. A column gear 11 is rotatably connected between the two rotating support plates 10 in each group. A ratchet 12 is fixedly connected to both of the two column gears 11.

[0023] It further includes a latch rod 13. The latch rod 13 is rotatably connected to each of the two rotating support plates 10 close to the ratchet wheel 12. A reed 14 is fixedly connected to each of the two rotating support plates 10 close to the ratchet wheel 12. The reed 14 and the latch rod 13 on the same side form a group. The reed 14 in the same group contacts the top of the latch rod 13. The reed 14 is used to keep the latch rod 13 in contact with the ratchet wheel 12 all the time, so that the ratchet wheel 12 cannot reverse.

[0024] It further includes a toothed rod 15. The toothed rod 15 is fixedly connected to both sides of the clamping ring 8. Each toothed rod 15 extends into a perforation formed in the lower fixing ring 2.

[0025] During the downward movement of the movable ring 4 and the clamping ring 8, the clamping ring 8 will drive the toothed rod 15 to descend. The toothed rod 15 descends through the perforation formed in the fixing ring 2. The toothed rod 15 will mesh with the spur gear 11. The toothed rod 15 drives the spur gear 11 to rotate. The rotation of the spur gear 11 drives the ratchet wheel 12 to rotate. The rotation of the ratchet wheel 12 will squeeze the latch rod 13. The latch rod 13 will swing upward under the extrusion. The upward swing of the latch rod 13 will squeeze the reed 14. The reed 14 will deform under the extrusion. When the ratchet wheel 12 no longer squeezes the latch rod 13, the reed 14 resets and drives the latch rod 13 to re - catch the ratchet wheel 12. In this way, the ratchet wheel 12 cannot reverse. The non - reversibility of the ratchet wheel 12 makes the spur gear 11 unable to reverse. The non - rotation of the spur gear 11 limits the toothed rod 15. In this way, the clamping ring 8 is limited to prevent the clamping ring 8 from loosening. When disassembly is required, the staff only needs to press down the latch rod 13 so that the latch rod 13 is disengaged from the ratchet wheel 12, and then the cable can be disassembled.

[0026] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
