[0032] Reference Figure 1The utility model provides a combined anti-vibration and shock-absorbing cable bridge, including a support frame 1, which is an existing cable bridge. A movable block 3 is arranged on the inner wall of the support frame 1. The movable block 3 is a clamping component as a whole, and is composed of structures such as a cross plate, a push rod and a first spring. This is the prior art and will not be explained here. A pressure plate 2 is fixedly connected to the outer wall of the movable block 3, and the pressure plate 2 is driven to move by the movable block 3 as a whole. A buffer component 5 is arranged on the outer wall of the support frame 1, and the buffer component 5 can have a certain buffering effect on the support frame 1 and thus protect the support frame 1. An adjustment component 4 is arranged on the inner wall of the bottom end of the support frame 1, and different types of cables can be clamped and fixed by the setting of the adjustment component 4.

[0033] Reference Figure 1-Figure 3 The adjusting component 4 includes a fixing plate 401, the bottom end of which is fixedly connected to the inner wall of the bottom end of the supporting frame 1. The fixing plate 401 can be provided with multiple groups, and the supporting frame 1 can play a certain supporting role on the fixing plate 401. The inner wall of the fixing plate 401 is elastically connected to the movable rod 404 through the connecting spring 406, and the outer wall of the movable rod 404 is rotatably connected to the connecting rod 403, and the elasticity of the connecting spring 406 can exert a certain reaction force on the movable rod 404. The outer wall of the connecting rod 403 is rotatably connected to the clamp 402, and the bottom end of the clamp 402 is fixedly connected to the positioning plate 405. The clamp 402 can adjust cables of different types, and the connecting rod 403 can be connected to the fixing plate 405. One end of the connecting spring 406 is fixedly connected to the inner wall of the fixed plate 401, and the other end of the connecting spring 406 is fixedly connected to the outer wall of the movable rod 404. The outer wall of the movable rod 404 is slidably connected to the inner wall of the fixed plate 401. The elasticity of the connecting spring 406 can reset the movable rod 404. The bottom end of the positioning plate 405 is fixedly connected to the inner wall of the fixed plate 401. The positioning plate 405 can provide a certain supporting force for the fixed plate 401. The clamp 402 is composed of two groups of arc plates, and the two groups of arc plates can rotate relative to each other. By opening the two groups of arc plates, it can adapt to different types of cables. The connecting spring 406 can drive the arc plates to reset.

[0034] Reference Figure 1 and Figure 4 The buffer assembly 5 includes a moving rod 504, the outer wall of the moving rod 504 is fixedly connected to the outer wall of the support frame 1, and the overall length of the two can be adjusted. The outer wall of the moving rod 504 is slidably connected to the limiting column 501, and the inner wall of the limiting column 501 is elastically connected to the movable plate 503 through the positioning spring 502. The positioning spring 502 can play a certain reset function on the movable plate 503. The outer wall of the movable plate 503 is fixedly connected to the support rod 505, and the support rod 505 plays a role in preventing it from falling off. The inner wall of the limiting column 501 is fixedly connected to the guide plate 506, and the inner wall of the guide plate 506 is provided with a wavy line groove. The shape of the moving rod 504 is T-shaped, and the T-shaped setting can prevent the moving rod 504 from falling off.

[0035] Reference Figure 4 One end of the positioning spring 502 is fixedly connected to the outer wall of the movable plate 503, and the other end of the positioning spring 502 is fixedly connected to the inner wall of the limit column 501. The outer wall of the support rod 505 is slidably connected to the inner wall of the guide plate 506. The elasticity of the positioning spring 502 can reset the movable rod 504. The outer wall of the movable plate 503 contacts the outer wall of the movable rod 504. The movable rod 504 moves horizontally, but the movable plate 503 moves in a wave-like manner. The contact between the two makes the movement trajectories non-interfering with each other.

[0036] Working principle: When relevant personnel need to install the cable tray, they first install the support frame 1, and then put the cable into the inner wall of the support frame 1. The cable will contact and squeeze the clamp 402, causing the clamp 402 to open. When the clamp 402 opens, the two sides of the clamp 402 will drive the connecting rods 403 at both ends to move accordingly, and then the connecting rod 403 will drive the movable rod 404 to move. At this time, the connecting spring 406 will be stretched, and the fixation is completed when the cable is completely in contact with the clamp 402. The opening of the clamp 402 can adapt to cables of different sizes, and the connecting spring 406 can provide a certain supporting effect on the clamp 402, and then move the movable block 3 downward, so that the movable block 3 drives the pressure plate 2 to move downward, so that the bottom end of the pressure plate 2 contacts the top of the cable to complete the fixing operation.

[0037] When the cable tray vibrates and shakes due to external force, the support frame 1 will drive the moving rod 504 to move. When the moving rod 504 moves, it will contact and squeeze the movable plate 503, causing the movable plate 503 to move. Then the movable plate 503 will contact and squeeze the positioning spring 502. When the movable plate 503 moves, it will cause the support rod 505 to move, and the support rod 505 will move in the guide groove opened by the guide plate 506, thereby achieving a better buffering effect.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
