Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and specifically relates to a cable tray. Background Technology

[0002] Cable trays are practical devices for "building a framework and channel" for wires and cables. Wherever there is a need for centralized cable routing (such as factory workshops, office buildings, community power distribution rooms, and even outdoor street light lines), cable trays are used to organize messy cables and prevent them from being pulled and dragged haphazardly.

[0003] In some existing cable trays, multiple rows of perforated mounting posts are installed inside. After the cables are placed, they are secured by binding straps that fit into the holes of the mounting posts. This prevents the cables from tangling and effectively reduces the risk of short circuits. However, workers need to use several binding straps to secure the cables one by one, which is a cumbersome process and has low work efficiency. When maintaining or disassembling the cables, several binding straps also need to be removed step by step, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray that, during use, uses the handle structure of the gripping plate and push rod to simultaneously drive all pushing and clamping components to achieve synchronous clamping and fixing of multiple cables, eliminating the need for staff to adjust the clamping components one by one, and greatly simplifying the operation process.

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

[0006] A cable tray, comprising

[0007] The main body of the cable tray has a cover plate snapped onto the top.

[0008] The assembly columns are arranged horizontally from front to back and assembled on the bottom side of the cable tray body. Each assembly column is equipped with a clamping mechanism at its top.

[0009] The clamping mechanism includes several first limiting plates, which are evenly arranged and installed on the top of the assembly column. Several sliding grooves are evenly arranged on the top of the assembly column, corresponding one-to-one with the positions of the several first limiting plates. Clamping components are slidably assembled inside the several sliding grooves.

[0010] As a preferred technical solution, the clamping assembly includes a slider, which is slidably assembled inside the slide groove. A second limiting plate is fixedly installed on the top of the slider. A first spring is fixedly installed on the side of the slider near the first limiting plate. One end of the first spring is fixedly connected to the inner wall of the slide groove. A through groove is opened at the lower front side of the assembly column. A pushing assembly is provided inside the through groove. An opening communicating with the through groove is opened at the bottom of the slide groove. The bottom of the slider is fixedly connected to the top of the pushing assembly.

[0011] As a preferred technical solution, the pushing component includes several L-shaped assembly plates, all of which are slidably connected to the through groove, and the tops of the several L-shaped assembly plates are respectively fixedly connected to the bottoms of several sliders.

[0012] Two L-shaped assembly plates, aligned front and back, are fixedly mounted on one side of each other with a drive rod. Several drive blocks are slidably assembled inside the central slot. Each drive block is located inside the L-shaped assembly plate corresponding to its position. Each pair of adjacent drive blocks is fixedly connected by a connecting block. The drive blocks and the L-shaped assembly plates are fixedly connected by bolts. Two L-shaped assembly plates extend from the front and back sides of the leftmost drive block. A locking component is provided between the leftmost drive block and the assembly column.

[0013] As a preferred technical solution, the locking assembly includes a locking block, a limiting post fixedly installed on the rear side of the central mounting post, several limiting grooves arranged at the bottom of the limiting post, an installation groove on the rear side of the top of the leftmost driving block, the locking block being slidably assembled inside the installation groove, a second spring fixedly installed at the bottom of the locking block, the lower end of the second spring being fixedly connected to the inner wall of the installation groove, an inclined surface on the upper right side of the locking block, the upper end of the locking block extending into one of the limiting grooves, a pull rope fixedly installed at the bottom of the locking block, one end of the pull rope extending out from the rear side of the driving block and fixedly installed with a pull block.

[0014] As a preferred technical solution, push rods are fixedly installed on both the front and rear sides of the leftmost driving block, and the left ends of the two push rods extend out of the cable tray body and are jointly fixedly installed with a holding plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. Simple and efficient operation: The handle structure of the grip plate and push rod can drive all the pushing and clamping components to move simultaneously, so as to achieve synchronous clamping and fixing of multiple cables. There is no need for staff to adjust the clamping components one by one, which greatly simplifies the operation process.

[0017] 2. Flexible and convenient maintenance: When adjusting the whole, the locking component can be quickly unlocked by pulling the block. With the first spring reset function, the clamping component can be reset after the push component is released. When maintaining a specific cable, only the bolts at the corresponding position need to be removed without affecting the fixation status of other cables. The reset and fixation after maintenance is also simple and efficient.

[0018] 3. Stable and reliable fixing: The locking component is pushed into the limiting groove by the second spring, which can stably lock the position of the pushing component and prevent the clamping component from loosening due to external force; the first limiting plate and the second limiting plate work together to clamp the cable, which can effectively limit the cable displacement and ensure the stability of the wiring.

[0019] 4. High adaptability: Several limiting grooves are opened at the bottom of the limiting post, which can adjust the clamping degree of the clamping component according to the cable diameter, adapting to the fixing needs of different specifications of cables, and has a wider range of applications.

[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-6 As shown, this utility model provides a cable tray, including...

[0030] The cable tray body 1 has a cover plate 11 snapped onto the top of the cable tray body 1;

[0031] Assembly column 2, several of which are arranged horizontally from front to back and assembled on the bottom side of the cable tray body 1. Each assembly column 2 is equipped with a clamping mechanism at its top.

[0032] The clamping mechanism includes several first limiting plates 3, which are evenly arranged and installed on the top of the assembly column 2. Several sliding grooves 31, each corresponding to a position of one of the first limiting plates 3, are evenly arranged on the top of the assembly column 2. Clamping components are slidably fitted inside each of the sliding grooves 31. In use, when the cable is passed through the cable tray body 1, there is a fixed space between each clamping component and each first limiting plate 3. The cable is passed through these fixed spaces sequentially. Subsequently, the clamping components are brought close to the first limiting plates 3 to fix and limit the cable, making the operation simple and convenient.

[0033] The clamping assembly includes a slider 4, which is slidably assembled inside the slide groove 31. A second limiting plate 41 is fixedly installed on the top of the slider 4. A first spring 42 is fixedly installed on the side of the slider 4 near the first limiting plate 3. One end of the first spring 42 is fixedly connected to the inner wall of the slide groove 31. A through groove 43 is opened at the lower front side of the assembly column 2. A pushing assembly is provided inside the through groove 43. An opening communicating with the through groove 43 is opened at the bottom of the slide groove 31. The bottom of the slider 4 is fixedly connected to the top of the pushing assembly.

[0034] When it is necessary to clamp the cable, the operator manually drives the push assembly to move, which can simultaneously move several second limit plates 41 close to several first limit plates 3, thereby clamping and fixing the cable. This eliminates the need for the operator to operate each one individually, reducing the operator's workload. After the push assembly is fixed, the positions of the several second limit plates 41 are fixed. After the push assembly is released from its fixed position, the elastic force of several first springs 42 can reset the push assembly, which facilitates subsequent cable maintenance by the operator.

[0035] The pushing component includes several L-shaped assembly plates 5, all of which are slidably connected to the through groove 43, and the tops of the several L-shaped assembly plates 5 are respectively fixedly connected to the bottoms of several sliders 4.

[0036] Two L-shaped assembly plates 5, aligned front to back and close to each other, are fixedly mounted with a drive rod 51. Several drive blocks 52 are slidably assembled inside the central through groove 43. The drive blocks 52 are located inside the L-shaped assembly plates 5 corresponding to their respective positions. Each pair of adjacent drive blocks 52 are fixedly connected by a connecting block 53. The drive blocks 52 and the L-shaped assembly plates 5 are fixedly connected by bolts. Two L-shaped assembly plates 5 extend from the front and rear sides of the leftmost drive block 52. A locking assembly is provided between the leftmost drive block 52 and the assembly column 2.

[0037] When the work pushes the leftmost driving block 52 to move, since each pair of adjacent driving blocks 52 is fixedly connected by a connecting block 53, and the L-shaped assembly plate 5 has an opening for the connecting block 53 to pass through, the leftmost driving block 52 can drive several driving blocks 52 to move synchronously. Because two L-shaped assembly plates 5 aligned front to back are fixedly mounted with a driving rod 51 close to each other on one side, and several driving blocks 52 are located inside the corresponding L-shaped assembly plates 5 and fixed with bolts, pushing one driving block 52 can move all the L-shaped assembly plates 5, thereby clamping and fixing several cables without having to proceed sequentially. When clamping and fixing, similarly, when contacting the clamp, the locking component is released from the leftmost driving block 52. Several first springs 42 generate a reverse thrust, which can push several second limit plates 41 away from several first limit plates 3. The operation is simple and easy to maintain. When only one cable needs to be maintained, the bolt connection at the corresponding position is released. In this way, the L-shaped assembly plate 5 at the corresponding position will be disengaged from the driving block 52. Therefore, the several second limit plates 41 at the corresponding position can be moved away from several first limit plates 3. This allows for cable maintenance at a specific position. Afterwards, the L-shaped assembly plate 5 can be pushed back to its original position and fixed with bolts again.

[0038] The locking assembly includes a locking block 6, a limiting post 61 fixedly installed on the rear side of the central mounting post 2, several limiting grooves 62 arranged at the bottom of the limiting post 61, an installation groove on the rear side of the top of the leftmost driving block 52, the locking block 6 is slidably assembled inside the installation groove, a second spring 63 is fixedly installed at the bottom of the locking block 6, the lower end of the second spring 63 is fixedly connected to the inner wall of the installation groove, an inclined surface 64 is opened on the upper right side of the locking block 6, the upper end of the locking block 6 extends into one of the limiting grooves 62, a pull rope 65 is fixedly installed at the bottom of the locking block 6, one end of the pull rope 65 extends out from the rear side of the driving block 52 and a pull block 66 is fixedly installed thereon.

[0039] Under normal conditions, under the elastic force of the second spring 63, the upper end of the locking block 6 will naturally engage with the corresponding limiting groove 62 at the bottom of the limiting post 61, thereby locking the position of the leftmost driving block 52 and thus fixing the clamping component by pushing the assembly. When it is necessary to release the clamp, simply pull the pull block 66. The pull rope 65 will then drive the locking block 6 to slide downwards against the elastic force of the second spring 63, causing its upper end to disengage from the limiting groove 62 and release the lock. At this time, pushing the grip plate 71 can move the driving block 52 and the entire pushing assembly. During the adjustment process, the inclined surface 64 on the right side of the locking block 6 will contact the bottom of the limiting post 61 and slide smoothly to avoid jamming. After adjusting to the target position, release the pull block 66. The second spring 63 will immediately reset and push the locking block 6 upwards, causing its upper end to re-engage with the corresponding limiting groove 62, completing the locking again and ensuring that the clamping component is stable in the adjusted position.

[0040] The leftmost drive block 52 has push rods 7 fixedly installed on both the front and rear sides. The left ends of the two push rods 7 extend out of the cable tray body 1 and are fixedly installed with a grip plate 71. The two push rods 7 and the grip plate 71 together form a handle, which is convenient for workers to push.

[0041] The device is used as follows: In the initial state, several first springs 42 are in a naturally relaxed state, which drives the slider 4 and the top second limiting plate 41 away from the first limiting plate 3, forming a fixed space for the cable to pass through; in the locking assembly, the second spring 63 pushes the upper end of the locking block 6 into the limiting groove 62 of the limiting post 61, locking the position of the leftmost driving block 52 and the pushing assembly; the two push rods 7 and the grip plate 71 form a handle structure, which is convenient for the operator to operate.

[0042] When fixing the cable, the worker first passes the cable to be laid through the fixing space between each first limiting plate 3 and the corresponding second limiting plate 41 in sequence. The worker holds the holding plate 71 and pushes it to the right, which drives the push rod 7 and the leftmost driving block 52 to move. Since the adjacent driving blocks 52 are fixed by the connecting block 53 and the driving block 52 is bolted to the L-shaped assembly plate 5, and the front and rear L-shaped assembly plates 5 are linked by the driving rod 51, all L-shaped assembly plates 5 can be moved synchronously along the through groove 43, thereby driving the slider 4 and the second limiting plate 41 to move closer to the first limiting plate 3. After the second limiting plate 41 and the first limiting plate 3 clamp the cable together, the pull block 66 is released, the second spring 63 resets and pushes the locking block 6 to move upward, re-clamping into the corresponding limiting groove 62, locking the position of the pushing component, and completing the cable fixing.

[0043] When it is necessary to adjust the cable position or perform overall maintenance, pull the pull block 66 to disengage the locking block 6 from the limit groove 62 to release the lock, and then the cable maintenance can be performed.

[0044] If only cable maintenance is required at a specific location, the worker can remove the connecting bolts between the drive block 52 and the L-shaped assembly plate 5 at that location, causing the corresponding L-shaped assembly plate 5 to disengage from the control of the push assembly. The first spring 42 will push the second limit plate 41 at that location away from the first limit plate 3. After maintenance is completed, the L-shaped assembly plate 5 will be pushed back to its original position and re-secured with bolts.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
