Description
A cable limiting structure for cable trench supports Technical Field
[0001] This utility model relates to the field of cable support technology, specifically a cable limiting structure for cable trench supports. Background Technology
[0002] Cable trench supports are mainly used to support and fix cables, ensuring that cables remain neat, stable and safe during the laying process. They are usually made of metal materials and are fixed to the trench wall by welding or screws. Cable limiting structures are an important part of cable trench supports. They are mainly used to fix and support cables to prevent them from swinging excessively or being damaged by external forces.
[0003] Existing cable limiting structures often suffer from cumbersome operation, poor limiting and fixing effect, and difficulty in removal for maintenance after installation. Specifically, traditional cable limiting mechanisms lack a flexible locking mechanism, making it difficult to quickly release the cable after installation for later maintenance. At the same time, the cable limiting process is complex, requiring multiple steps and tools, which is not only time-consuming and labor-intensive, but may also affect the limiting effect due to improper operation, thus failing to effectively guarantee the stability and safety of the cable.
[0004] Therefore, a cable limiting structure for cable trench supports is needed to solve the problems of cumbersome installation process and difficulty in removal and maintenance after installation in the existing technology. Summary of the Invention
[0005] The purpose of this utility model is to provide a cable limiting structure for cable trench supports, so as to solve the problems of cumbersome installation process and difficulty in removal and maintenance after installation in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable limiting structure for a cable trench support, comprising a support frame, wherein two parallel mounting plates are fixedly connected to the outer right side of the support frame, and multiple evenly distributed U-shaped seats are fixedly connected to the top surface of each of the two mounting plates, wherein a limiting mechanism is provided inside each U-shaped seat, and a top plate is provided on the top surface of each U-shaped seat, and a reinforcing rod is fixedly connected between the bottom surface of the two mounting plates and the outer right side of the support frame;
[0007] Each set of limiting mechanisms includes four fixed blocks, which are arranged in pairs and fixedly connected to the inner walls of both sides of the U-shaped seat. A vertical rod is fixedly connected between two fixed blocks on the same side. A movable block is slidably sleeved on the outer surface of the vertical rod, and a spring is sleeved on the outer surface of the vertical rod. A connecting rod is rotatably connected to the outer wall of the movable block away from the U-shaped seat. A limiting plate is rotatably connected to the end of the connecting rod away from the movable block. Auxiliary rods are fixedly connected to the outer walls of both ends of the movable block.
[0008] It should be noted in the solution that a support seat is fixedly connected to the center of the inner wall of the bottom surface of each U-shaped seat, and guide rods are fixedly connected between the outer walls of the two sides of the support seat and the inner walls of the two sides of the corresponding U-shaped seat. A sliding rod is slidably sleeved on the outer surface of the guide rod.
[0009] It is worth noting that each of the top plates has a screw threaded into its top surface. The bottom end of the screw thread passes through the bottom surface of the corresponding top plate and is coaxially rotatably connected to a pressure plate. Extension plates are fixedly connected to both outer walls of the pressure plate, and a screw cap is coaxially fixedly connected to the top end of the screw.
[0010] Furthermore, it should be noted that each of the U-shaped seats has two parallel support plates fixedly connected to the left side of its top surface, and a fixing plate fixedly connected to the outer wall of the right side of each U-shaped seat. The top surface of the fixing plate is rotatably connected to two parallel rotating shafts, and the outer surface of the rotating shafts is fastened with buckles. Each top plate has two through holes on the right side of its top surface that correspond one-to-one with the buckles.
[0011] In a preferred embodiment, the top and bottom ends of each spring are respectively fixedly connected to the bottom surface of the corresponding moving block and the top surface of the corresponding fixed block, and each top plate is rotatably connected between the two support plates on the top surface of the corresponding U-shaped seat.
[0012] In a preferred embodiment, the top surface of each slide bar is fixedly connected to the bottom surface of the corresponding limiting plate, and the length of the through hole is greater than the length of the buckle.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Through the cooperation of the rotating shaft, the buckle and the through hole, after the top plate is rotated, the rotating shaft drives the buckle to rotate, locking the top plate and preventing the cable from coming out of the U-shaped seat. Similarly, when the cable is inspected, it is easy to take the cable out of the U-shaped seat. It is highly flexible and effectively avoids the problem of the cable being difficult to remove for inspection after the cable is limited and installed.
[0015] 2. The screw drives the pressure plate to move, which in turn pushes the extension plate to drive the auxiliary rod to move the moving block. The moving block then pushes the limit plate to move through the connecting rod. The pressure plate and the two limit plates simultaneously clamp and fix the cable, achieving rapid limit installation of the cable. The limit fixing effect is good, the operation is simple, and it effectively avoids the cumbersome process of cable limit installation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: As shown in Figures 1-4, this utility model provides a technical solution including a support frame 1. Two parallel mounting plates 2 are fixedly connected to the outer right side of the support frame 1. Multiple evenly distributed U-shaped seats 3 are fixedly connected to the top surface of the two mounting plates 2. Each U-shaped seat 3 is provided with a limit mechanism 4 inside. Each U-shaped seat 3 is provided with a top plate 5 on its top surface. A reinforcing rod 6 is fixedly connected between the bottom surface of the two mounting plates 2 and the outer right side of the support frame 1.
[0023] Each set of limiting mechanisms 4 includes four fixed blocks 41. The four fixed blocks 41 are arranged in pairs and are fixedly connected to the inner walls of both sides of the U-shaped seat 3. The same vertical rod 42 is fixedly connected between two fixed blocks 41 on the same side. A movable block 43 is slidably sleeved on the outer surface of the vertical rod 42. A spring 44 is sleeved on the outer surface of the vertical rod 42. A connecting rod 45 is rotatably connected to the outer wall of the movable block 43 away from the U-shaped seat 3. A limiting plate 46 is rotatably connected to the end of the connecting rod 45 away from the movable block 43. Auxiliary rods 47 are fixedly connected to the outer walls of both ends of the movable block 43.
[0024] As further shown in Figures 2, 3 and 4, it is worth noting that a support seat 7 is fixedly connected to the center of the inner wall of the bottom surface of each U-shaped seat 3. Guide rods 8 are fixedly connected between the outer walls on both sides of the support seat 7 and the inner walls on both sides of the corresponding U-shaped seat 3. A sliding rod 9 is slidably sleeved on the outer surface of the guide rod 8.
[0025] As further shown in Figures 2, 3 and 4, it is worth noting that each top plate 5 has a screw 10 threadedly inserted into its top surface. The bottom end of the screw 10 is threaded through the bottom surface of the corresponding top plate 5 and is coaxially rotatably connected to a pressure plate 11. Extension plates 12 are fixedly connected to both outer walls of the pressure plate 11, and a screw cap 13 is coaxially fixedly connected to the top end of the screw 10.
[0026] Further, as shown in Figures 2, 3 and 4, it is worth noting that each U-shaped seat 3 has two parallel support plates 14 fixedly connected to the left side of its top surface, and each U-shaped seat 3 has a fixed plate 15 fixedly connected to the outer wall of its right side. The top surface of the fixed plate 15 is rotatably connected to two parallel rotating shafts 16, and the outer surface of the rotating shafts 16 is fastened with buckles 17. Each top plate 5 has two through holes 18 on the right side of its top surface that correspond one-to-one with the buckles 17.
[0027] Further, as shown in Figures 2, 3, and 4, it is worth noting that the top and bottom ends of each spring 44 are respectively fixedly connected to the bottom surface of the corresponding moving block 43 and the top surface of the corresponding fixed block 41. When the extension plate 12 no longer presses down on the auxiliary rod 47, the spring 44 can push the moving block 43 to quickly separate the limiting plate 46 from the cable through the connecting rod 45, thereby quickly releasing the limitation on the cable. Each top plate 5 is rotatably connected between the two support plates 14 on the top surface of the corresponding U-shaped seat 3. By rotating the top plate 5, it is easy to put the cable into the U-shaped seat 3 or take it out from the U-shaped seat 3.
[0028] As further shown in Figures 2, 3 and 4, it is worth noting that the top surface of each slide bar 9 is fixedly connected to the bottom surface of the corresponding limiting plate 46 to guide the movement direction of the limiting plate 46 and improve the stability of the limiting plate 46 when it moves. The length of the through hole 18 is greater than the length of the buckle 17 to avoid interference from the rotating shaft 16 when the top plate 5 rotates.
[0029] In summary: When installing and limiting the cable, first rotate the top plate 5 away from the corresponding U-shaped seat 3. After placing the cable on the top surface of the support seat 7, rotate the top plate 5 in the opposite direction to seal the top surface of the U-shaped seat 3. Then, rotate the two rotating shafts 16, which drive the buckle 17 to rotate. When the buckle 17 rotates from the horizontal state to the vertical state, the bottom surface of the buckle 17 is in contact with the top surface of the top plate 5 to a certain extent, thus locking the top plate 5 and preventing the cable from coming out of the U-shaped seat 3. Similarly, when the cable is being inspected, it is easy to remove the cable from the U-shaped seat 3, which is highly flexible and effectively avoids the problem of the cable being difficult to remove for inspection after installation.
[0030] After locking the top plate 5, rotate the screw cap 13 to drive the screw 10 to rotate. Under the action of the thread, the screw 10 pushes the pressure plate 11 to move downward. During this process, the pressure plate 11 pushes the auxiliary rod 47 through the extension plate 12 to drive the moving block 43 to slide downward. The moving block 43 squeezes the spring 44 and pushes the limiting plate 46 to move along the direction of the guide rod 8 through the connecting rod 45. The pressure plate 11 and the two limiting plates 46 move towards the cable at the same time to clamp and fix the cable placed on the support seat 7, thereby realizing the rapid limiting installation of the cable. The limiting and fixing effect is good, the operation is simple, and the problem of cumbersome process during cable limiting installation is effectively avoided.
