Description

A cable tray for easy cable fixing Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray that facilitates cable fixing. Background Technology

[0002] Cable trays are a structured support system used to safely and orderly arrange and support cables, wires and other cables inside or outside buildings. They are usually made of metal, non-metal or composite materials and have the functions of protecting cables from damage, optimizing layout, and improving system reliability and maintainability.

[0003] To prevent cables from shifting loosely within the cable tray, cable ties are typically used to secure them. However, when cables need to be inspected or replaced, tools are needed to cut the cable ties, and new cable ties are required to re-secure the cables, making the process very inconvenient. Therefore, we propose a cable tray design that facilitates cable securing. Summary of the Invention

[0004] The main purpose of this utility model is to provide a cable tray that facilitates cable fixing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable tray for easy cable fixing includes a U-shaped cable tray with a top cover movably connected to the top of the U-shaped cable tray, and the top cover is in the shape of an inverted U.

[0007] Furthermore, a support block is fixedly installed on the bottom wall of the U-shaped cable tray, a fixing ring is fixedly installed on the top of the support block, a guide rod is symmetrically fixedly installed on one side of the fixing ring, a first spring is symmetrically fixedly installed on one side of the fixing ring, a movable ring is fixedly connected to the tail end of the first spring, a connecting block is fixedly installed on the outer surface of the movable ring, a connecting rod is rotatably connected to the inner wall of the connecting block, a movable block is rotatably connected to the tail end of the connecting rod, and a clamping block is fixedly installed at the tail end of the movable block.

[0008] Furthermore, the number of support blocks is set in multiple sets, the guide rod is slidably connected to the inner wall of the movable ring, the movable block is slidably connected to the inner wall of the fixed ring, and the first spring is movably sleeved on the outer surface of the guide rod.

[0009] Furthermore, the top wall of the upper cover is symmetrically and fixedly equipped with plug-in blocks, the inner wall of the plug-in blocks is movably connected to limit blocks, the outer surface of the limit blocks is fixedly equipped with pull rods, and the outer surface of the limit blocks is fixedly connected to second springs.

[0010] Furthermore, the plug-in block is movably connected to the inner wall of the U-shaped cable tray, the limiting block is slidably connected to the inner wall of the U-shaped cable tray, the pull rod is slidably connected to the inner wall of the U-shaped cable tray, and the front end of the pull rod moves through to the outer side of the U-shaped cable tray. The tail end of the second spring is fixedly connected to the inner wall of the U-shaped cable tray, and the second spring is movably sleeved on the outer surface of the pull rod.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0012] In this invention, a movable ring, a first spring, a connecting rod, and a movable block are configured. Pushing the movable ring causes the clamping block to move in a dispersed manner, facilitating the cable to pass through the fixed ring. Releasing the movable ring allows the clamping block to close together with the cooperation of the first spring and the connecting rod, until the cable is clamped. This achieves the purpose of quickly clamping and fixing cables of different diameters. Pushing the movable ring again releases the cable from the fixation, facilitating cable disassembly. The operation is simple and convenient, requiring no other tools. By setting a limiting block, the top cover and the U-shaped cable tray can be quickly fixed together. Pulling the pull rod releases the fixation between the top cover and the U-shaped cable tray, allowing the top cover to be removed. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Referring to Figures 1-5, a cable tray for easy cable fixing includes a U-shaped cable tray 1, with a top cover 2 movably connected to the top of the U-shaped cable tray 1, and the top cover 2 is in the shape of an inverted U.

[0021] In a preferred embodiment, a support block 101 is fixedly installed on the bottom wall of the U-shaped cable tray 1, a fixing ring 102 is fixedly installed on the top of the support block 101, a guide rod 103 is symmetrically fixedly installed on one side of the fixing ring 102, and a first spring 104 is symmetrically fixedly installed on one side of the fixing ring 102. A movable ring 109 is fixedly connected to the tail end of the first spring 104. The movable ring 109 can slide horizontally along the trajectory of the guide rod 103. By setting the guide rod 103, the stability of the movable ring 109 is effectively improved. When ring 109 slides toward fixed ring 102, it will compress the first spring 104. When the compressing force disappears, the first spring 104 can drive the movable ring 109 away from the fixed ring 102. A connecting block 108 is fixedly installed on the outer surface of the movable ring 109. A connecting rod 107 is rotatably connected to the inner wall of the connecting block 108. A movable block 105 is rotatably connected to the tail end of the connecting rod 107. The movable block 105 is connected to the movable ring 109 through the connecting rod 107 and the connecting block 108. A clamping block 106 is fixedly installed at the tail end of the movable block 105.

[0022] In a preferred embodiment, the number of support blocks 101 is arranged in multiple sets, the guide rod 103 is slidably connected to the inner wall of the movable ring 109, the movable block 105 is slidably connected to the inner wall of the fixed ring 102, the fixed ring 102 can restrict the movement of the movable block 105, and the first spring 104 is movably sleeved on the outer surface of the guide rod 103.

[0023] When laying the cable, the movable ring 109 is pushed towards the fixed ring 102. At this time, the first spring 104 is compressed. During the movement of the movable ring 109, the connecting block 108 moves synchronously. Then, under the linkage of the connecting rod 107, the several sets of movable blocks 105 gradually disperse, making the area enclosed by the several sets of movable blocks 105 larger, so that the cable can pass smoothly through the movable ring 109 and the fixed ring 102. After the cable passes through the movable ring 109 and the fixed ring 102, the movable ring 109 is released. At this time, the first spring 104 rebounds, which in turn causes the movable ring 109 to slide in the opposite direction. The linkage 107 causes several sets of movable blocks 105 to gradually move closer together until several sets of clamping blocks 106 clamp the cable, thereby achieving the purpose of fixing the cable. It can also adapt to cables of different diameters, effectively improving the flexibility and practicality of the device. When it is necessary to repair or replace the cable, the movable ring 109 is pushed towards the fixed ring 102 again. With the cooperation of the linkage 107 and the movable blocks 105, the clamping blocks 106 are moved away from the cable, thereby releasing the clamping and fixing of the cable. Then the cable can be pulled out from the fixed ring 102 and the movable blocks 105. The operation is simple and quick, without the need for other tools.

[0024] In a preferred embodiment, plug-in blocks 201 are symmetrically fixedly installed on the top wall of the upper cover 2. The plug-in blocks 201 are distributed around the top wall of the upper cover 2. Limiting blocks 202 are movably connected to the inner wall of the plug-in blocks 201. Pull rods 203 are fixedly installed on the outer surface of the limiting blocks 202. A second spring 204 is fixedly connected to the outer surface of the limiting blocks 202. Pulling the pull rod 203 will cause the limiting blocks 202 to be pulled and squeeze the second spring 204. When the pulling force is removed, the second spring 204 can drive the limiting blocks 202 and the pull rod 203 to spring back to their original positions.

[0025] In a preferred embodiment, the plug block 201 is movably connected to the inner wall of the U-shaped cable tray 1, the limiting block 202 is slidably connected to the inner wall of the U-shaped cable tray 1, the pull rod 203 is slidably connected to the inner wall of the U-shaped cable tray 1, and the front end of the pull rod 203 moves through to the outer side of the U-shaped cable tray 1. The tail end of the second spring 204 is fixedly connected to the inner wall of the U-shaped cable tray 1, and the second spring 204 is movably sleeved on the outer surface of the pull rod 203.

[0026] After the cable is fixed inside the U-shaped cable tray 1, align the plug block 201 on the upper cover 2 with the slot at the top of the U-shaped cable tray 1. Then, place the upper cover 2 vertically downwards so that the plug block 201 is inserted into the slot. When the plug block 201 moves downwards and contacts the inclined surface of the limiting block 202, the plug block 201 will press against the limiting block 202, causing the limiting block 202 to move horizontally. At this time, the second spring 204 is compressed. When the notch on the plug block 201 aligns with the limiting block 202, the second spring 204 will move... The limiting block 202 and the pull rod 203 rebound, causing the front end of the limiting block 202 to insert into the plug block 201, thereby fixing the plug block 201 inside the U-shaped cable tray 1, and thus fixing the top cover 2 to the U-shaped cable tray 1, thereby completing the quick installation of the top cover 2. When it is necessary to remove the top cover 2, pull the pull rod 203 to disengage the limiting block 202 from the plug block 201, thereby releasing the fixation between the top cover 2 and the U-shaped cable tray 1. Then, lift the top cover 2 upwards to easily remove the top cover 2.

[0027] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
