DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A cable support device with a buffer structure includes a traction seat 1, a conveying ring 2 is fixed inside the traction seat 1, a rotating ring 6 is provided between the conveying ring 2 and the traction seat 1, and the rotating ring 6 is rotatably connected to the inner wall of the traction seat 1, wherein the conveying ring 2 is provided with circumferentially distributed conveying rollers 3, the conveying rollers 3 are connected to the rotating ring 6 through a buffer mechanism 4, the buffer mechanism 4 is used for elastic support of the conveying rollers 3, and a plurality of staggered arc plates 9 are provided inside the conveying ring 2, the arc plates 9 are connected to a driving mechanism 5, and the driving mechanism 5 is used to drive the plurality of arc plates 9 to move relative to each other.

[0023] In the present embodiment, when the cable is pulled, the device passes the cable through the inside of the conveying ring 2. When the cable passes through the inside of the conveying ring 2, it passes through a plurality of conveying rollers 3 and a plurality of arc plates 9 in sequence. The conveying rollers 3 support the cable. The cable and the plurality of conveying rollers 3 are all rollingly connected, which can effectively reduce the friction between the conveying ring 2 and the cable, and facilitate the pulling of the cable by the staff. At the same time, it can also avoid the damage to the cable caused by the side wall of the conveying ring 2, and play a protective role for the cable. When the cable is pulled, the driving mechanism 5 drives the plurality of arc plates 9 to move synchronously. The arc plates 9 can squeeze the cable while moving until the arc plates 9 press the cable against the inner wall of the conveying ring 2, thereby playing a pressing and fixing role on the cable, effectively improving the stability of the cable and the cross-connection. The staggered arc plate 9 can not only press and hold the cable, but also bend the cable. On the one hand, it enables the cable to move toward the inside of the conveying ring 2, which has a gathering effect on the cable and reduces the length of the cable outside the conveying ring 2. On the other hand, it can increase the friction between the cable and the arc plate 9, thereby improving the fixing effect of the arc plate 9 on the cable, ensuring the stability of the cable. When the cable is subjected to external tension, the cable will squeeze one of the conveying rollers 3. At this time, the rotating ring 6 can buffer the cable through the buffer mechanism 4, thereby avoiding damage to the cable caused by the rigid contact between the cable and the conveying ring 2. The number of conveying rollers 3 can be four, so that no matter in which direction the cable is subjected to pressure, the conveying roller 3 can buffer the cable, effectively improving the protection performance of the cable.

[0024] See also Figure 2 and Figure 3 The buffer mechanism 4 includes a bracket 41 rotatably connected to the conveying roller 3, the bracket 41 is connected to the inner wall of the conveying ring 2 through a first elastic component 42, the bracket 41 is fixedly connected to a support rod 43, the support rod 43 penetrates the side wall of the conveying ring 2 and is slidably connected to the side wall of the conveying ring 2, and one end of the support rod 43 away from the bracket 41 is rotatably connected to a connecting rod 44, and the other end of the connecting rod 44 is rotatably connected to the rotating ring 6; When the cable is subjected to external tension, the cable squeezes one of the conveying rollers 3, and the conveying roller 3 squeezes the first elastic component 42 through the bracket 41. The first elastic component 42 can be a spring. The first elastic component 42 plays a buffering role on the cable through the bracket 41 and the conveying roller 3, thereby avoiding damage to the cable caused by the rigid contact between the cable and the conveying ring 2. When the bracket 41 is squeezed, it also drives the support rod 43 to move, and the support rod 43 drives the rotating ring 6 to rotate through the connecting rod 44.

[0025] See also Figure 2The inner wall of the traction seat 1 is provided with a plurality of arc grooves 8 distributed in a circumference, and the outer wall of the rotating ring 6 is provided with a plurality of sliders 7 distributed in a circumference and adapted to the arc grooves 8, and the sliders 7 are located inside the arc grooves 8 and are slidably connected to the arc grooves 8; The rotating ring 6 drives the slider 7 to slide inside the arc groove 8 while rotating. The arc groove 8 limits the rotating ring 6 through the slider 7, thereby effectively improving the stability of the rotating ring 6 during rotation.

[0026] See also Figure 4 The driving mechanism 5 includes a slide bar 52 fixedly connected to the arc plate 9, the slide bar 52 passes through the conveying ring 2 and the traction seat 1, and a traction plate 53 is fixed to one end of the slide bar 52 outside the traction seat 1, and the traction plate 53 is connected to a traction assembly, and the traction assembly is used to drive multiple traction plates 53 to move synchronously toward the traction seat 1. A second elastic component 51 is provided outside the slide bar 52, and both ends of the second elastic component 51 are fixedly connected to the arc plate 9 and the inner wall of the conveying ring 2 respectively; When the cable is laid, the traction assembly drives multiple traction plates 53 to move synchronously toward the traction seat 1. The traction plate 53 drives the arc plate 9 to move through the slide rod 52, so that the arc plate 9 presses the cable against the inner wall of the conveying ring 2, and then gathers the cable to the inner wall of the conveying ring 2. At the same time, the stability of the cable can also be ensured. The second elastic component 51 can be a spring, which can play a resetting role on the arc plate 9.

[0027] See also Figure 2 and Figure 4 The traction assembly includes fixed blocks 55 fixed to the outside of the traction seat 1 and symmetrically distributed, the fixed blocks 55 are rotatably connected to the rotating rods 57, one end of the rotating rods 57 passes through one of the fixed blocks 55, a plurality of winding rollers 56 are fixed to the outside of the rotating rods 57, the winding rollers 56 are all fixedly connected to the pull ropes 54, the other end of the pull ropes 54 is fixedly connected to the traction plate 53, one of the fixed blocks 55 is provided with a fixing component inside, the fixing component is used to fix the rotating rod 57; When the cable is laid, the rotating rod 57 is rotated, and the rotating rod 57 drives the winding roller 56 to rotate. The winding roller 56 reels the pull rope 54 while rotating, and the pull rope 54 pulls the traction plate 53, so that the traction plate 53 drives the arc plate 9 to press the cable synchronously through the sliding rod 52. When the arc plate 9 presses the cable on the inner wall of the conveying ring 2, the fixing component inside one of the fixing blocks 55 just fixes the rotating rod 57, thereby ensuring the stability of the rotating rod 57, and then ensuring the fixing effect of the arc plate 9 on the cable.

[0028] See also Figure 2 and Figure 5The fixing member includes a slot 58 disposed outside the rotating rod 57, and a rod 59 adapted to the slot 58 is passed through the side wall of the fixing block 55. One end of the rod 59 is in contact with the side wall of the rotating rod 57, and a baffle 511 is fixed to the other end of the rod 59. The baffle 511 is connected to the side wall of the fixing block 55 through a third elastic member 510; When the arc plate 9 presses the cable against the inner wall of the conveying ring 2, the slot 58 on the side wall of the rotating rod 57 is aligned with the clamping rod 59. Under the action of the third elastic component 510 and the baffle 511, the clamping rod 59 automatically enters the slot 58. The clamping rod 59 fixes the rotating rod 57 through the slot 58, thereby ensuring the fixing effect of the arc plate 9 on the cable, wherein the third elastic component 510 can be a spring.

[0029] See also Figure 3 and Figure 5 A traction rope 512 is fixed on the side wall of the rotating ring 6, and a channel is passed through the side wall of the traction seat 1. The traction rope 512 passes through the channel and is fixedly connected to the baffle 511; When the cable is subjected to external tension, the cable squeezes the conveying roller 3, and the buffer mechanism 4 buffers the cable through the conveying roller 3. When the conveying roller 3 is squeezed, the buffer mechanism 4 drives the rotating ring 6 to rotate, and the rotating ring 6 pulls the baffle 511 through the traction rope 512. When the cable is subjected to a large external tension, the conveying roller 3 is squeezed to the maximum extent, and the buffer mechanism 4 reaches the buffering limit. At this time, the traction rope 512 just pulls the slot 58 out of the inside of the slot 58 through the baffle 511, and the limit of the card rod 59 is lost. The arc plate 9 automatically resets under the action of the second elastic component 51, and the arc plate 9 no longer squeezes the cable. The cable is automatically straightened under the action of the external tension, thereby achieving the effect of releasing the line in the same direction, effectively avoiding damage to the cable caused by the large external tension.

[0030] See also Figure 5 A guide column 513 is fixed to the outside of the traction seat 1, and a guide groove is passed through the inside of the guide column 513, and the guide groove is connected to the channel, wherein the traction rope 512 passes through the inside of the guide groove; The guide column 513 and the guide groove can guide the traction rope 512 , so that the baffle 511 can be vertically stressed, making it easier for the traction rope 512 to pull the baffle 511 .

[0031] Working principle: When the device is pulling the cable, the cable passes through the inside of the conveying ring 2, and the conveying roller 3 supports the cable. The cable and multiple conveying rollers 3 are all connected in a rolling manner, which can effectively reduce the friction between the conveying ring 2 and the cable, making it convenient for the staff to pull the cable, and at the same time avoid the damage to the cable caused by the side wall of the conveying ring 2, which plays a protective role for the cable. When the cable is pulled, the rotating rod 57 is rotated, and the rotating rod 57 drives the winding roller 56 to rotate. The winding roller 56 rotates and reels the pull rope 54, so that the pull rope 54 is pulled The traction plate 53 is moved, and the traction plate 53 moves while driving the arc plate 9 to move through the slide bar 52. When the arc plate 9 presses the cable on the inner wall of the conveying ring 2, the slot 58 on the side wall of the rotating rod 57 is aligned with the clamping rod 59, and the clamping rod 59 automatically enters the inside of the slot 58. The clamping rod 59 fixes the rotating rod 57 through the slot 58, thereby ensuring the fixing effect of the arc plate 9 on the cable, effectively improving the stability of the cable, and the staggered arc plates 9 can also bend the cable while pressing the cable, so that The cable can move toward the inside of the conveying ring 2, which has a gathering effect on the cable, reduces the length of the cable outside the conveying ring 2, and improves the aesthetic performance. On the other hand, it can increase the friction between the cable and the arc plate 9, and improve the fixing effect of the arc plate 9 on the cable. When the cable is subjected to external tension, the cable squeezes one of the conveying rollers 3, and the conveying roller 3 squeezes the first elastic component 42 through the bracket 41. The first elastic component 42 plays a buffering role on the cable through the bracket 41 and the conveying roller 3, thereby avoiding the rigid contact between the cable and the conveying ring 2 and the cable. The damage caused, wherein the bracket 41 is squeezed and the support rod 43 is driven to move, and the support rod 43 drives the rotating ring 6 to rotate through the connecting rod 44. When the cable is subjected to a large external tension, the conveying roller 3 is squeezed to the maximum extent. At this time, the traction rope 512 just pulls the card slot 58 out of the card slot 58 through the baffle 511, and the limit of the card rod 59 is lost. The arc plate 9 automatically resets, and the arc plate 9 no longer squeezes the cable. The cable is automatically straightened under the action of the external tension, thereby achieving the effect of releasing the line in the direction of the trend, which can effectively avoid damage to the cable caused by the large external tension.
