Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically a sliding telescopic cable tray. Background Technology
[0002] Cable trays are commonly used for laying cables in power and communication industries. They are widely used in cable organization and protection scenarios in construction, industry and other fields. Their structural design needs to meet the functional requirements of cable layout, installation and maintenance in different construction environments. In particular, when facing different spatial lengths or layout scenarios that need to be dynamically adjusted, higher requirements are placed on the adaptability of the cable tray itself.
[0003] Existing cable tray technologies have certain limitations in practical applications: First, traditional cable tray structures are mostly of fixed length, making it difficult to flexibly adjust the length according to actual site requirements. When facing installation scenarios with different spans or needing to dynamically change the layout length, additional splicing or cutting methods are often required, which are cumbersome and have poor adaptability. Second, the connection and fixing methods between the cable tray and the external structure are relatively simple, resulting in insufficient connection stability. Under external forces or during long-term use, loosening and displacement are likely to occur. Third, some cable trays with telescopic functions lack effective buffering and shock absorption designs during the telescopic process. The impact force generated during telescopic movement can easily cause the cable tray to vibrate, which not only affects the stability of the cable arrangement but may also cause jamming and uneven sliding. In addition, the poor structural sealing makes it easy for dust and debris to intrude, affecting the service life of the cable tray and the safety of cable operation. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a sliding telescopic cable tray to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sliding telescopic cable tray, comprising:
[0006] The main body of the cable tray, as well as the upper cable limiting frame and the lower cable tray mounting frame that make up the main body of the cable tray, and the bottom center of the upper cable limiting frame and the top center of the lower cable tray mounting frame are both provided with slide rails.
[0007] A sliding limit block is set at the center of the perimeter between the upper cable limit frame and the lower cable tray mounting frame, and is slidably connected to the slide rail. A threaded hole is installed at the center of the corresponding position of the sliding limit block.
[0008] Magnetic suction components are located at the front and rear ends of the threaded holes and are inserted and connected to the corresponding sliding limit blocks. Nail holes are provided on both sides of the center between the tops of adjacent magnetic suction components. After the sliding limit blocks are first installed inside the slide rails of the upper cable tray support and the lower cable tray mounting bracket, the sliding limit blocks can move along the slide rails. The sliding limit blocks can be connected to the mounting wall or building surface through the threaded holes, magnetic suction components, and nail holes, thus enabling staggered installation of the upper and lower layers of the cable tray within a certain range. This allows for length adjustment and meets the needs of different length scenarios.
[0009] Preferably, the upper cable limiting frame and the lower cable tray mounting frame are connected by slide rails on all four sides, and the upper cable limiting frame has a longitudinally spaced mounting hole at its top center. C-shaped brackets can be detachably inserted into the inner walls of both the upper cable limiting frame and the lower cable tray mounting frame. The upper cable limiting frame and the lower cable tray mounting frame are connected by C-shaped brackets, which limit the movement of the upper and lower structures, facilitating stable handling. The sliding limiting block can move in a circle along the slide rails of the upper cable limiting frame and the lower cable tray mounting frame. Compared to some slide rail structures that can only move back and forth, this structure offers higher operability and practicality.
[0010] Preferably, the sliding limit block has a Z-shaped design, and its back side fits snugly against the upper cable limiting frame and the lower cable tray mounting frame. The threaded holes, magnetic fasteners, and nail holes are all located at corresponding positions on the lower front side of the sliding limit block. The sliding limit block can move by fitting against the outer wall of the upper cable limiting frame and the lower cable tray mounting frame.
[0011] Preferably, each sliding limit block has a longitudinally spaced limit hole at its top center, which corresponds in shape and position to the mounting hole, and a limit post is longitudinally inserted into the inner cavity of each limit hole. The limit post can be inserted into the interior of the limit hole and the mounting hole of the sliding limit block.
[0012] Preferably, the top of the limiting post is provided with anti-slip grooves on all four sides, and the limiting post is cylindrical in shape. The bottom end of the limiting post passes through the limiting hole and is inserted into the mounting hole. The lower part of the limiting post passes through the limiting hole and is inserted into the mounting hole, so that the sliding limiting block is connected to the upper cable limiting frame, thereby preventing the sliding limiting block from moving on the upper cable limiting frame and the lower cable tray mounting frame.
[0013] Preferably, each sliding limit block is equipped with a telescopic double-ended rod at its center on the back side, and a compression spring is fitted onto the surface of the telescopic ends at the top and bottom of each telescopic double-ended rod. A sliding post is installed at the telescopic end of each telescopic double-ended rod and inserted into the corresponding slide rail cavity, fitting tightly against the inner wall of the slide rail. Under the action of the compression spring, the telescopic end of the telescopic double-ended rod drives the corresponding sliding post to extend outward and insert into the corresponding slide rail. The sliding limit block slides on the slide rail via the sliding post, facilitating the disassembly and replacement of the sliding limit block with the slide rail.
[0014] Compared with the prior art, this utility model provides a sliding telescopic cable tray, which has the following advantages:
[0015] This sliding telescopic cable tray uses a slide rail between the upper cable limiting frame and the lower cable tray mounting frame in the main body of the cable tray, and a sliding connection with the sliding limiting block, to achieve staggered installation of the upper and lower layers of the cable tray, thus realizing the length extension and adjustment to meet the usage needs of different length scenarios.
[0016] The threaded holes and magnetic components on the sliding limit block facilitate connection and fixation with external structures, and the nail holes at the top of the adjacent magnetic components can further enhance the stability of the connection.
[0017] The telescopic double-headed rod on the back of the sliding limit block is fitted with a compression spring. The sliding column at its telescopic end is inserted into the slide rail. The spring's elasticity can buffer the impact force during the extension and retraction of the bridge frame, reducing vibration. At the same time, the design that fits tightly against the inner wall of the slide rail ensures smoothness and sealing during the sliding process. Attached Figure Description

Detailed Implementation
[0022] 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.
[0023] This utility model provides a technical solution: a sliding telescopic cable tray, comprising: (see details) Figure 1 The cable tray body 1, and the upper cable limiting frame 2 and lower cable tray mounting frame 3 that make up the cable tray body 1, can all have sealing plates installed on the surfaces of both the upper and lower structures through threaded structures to achieve the effect of a drawer-type passage. The installation method can be either suspended or upright, i.e., it can be... Figure 1 Place it either on its own or flip it upside down, and install it according to the actual usage requirements. The bottom center of the upper cable limit bracket 2 and the top center of the lower cable tray mounting bracket 3 are both provided with slide rails 4.
[0024] Please see Figure 3 The sliding limit block 5 is located at the center of the perimeter between the upper cable limit frame 2 and the lower cable tray mounting frame 3, and is slidably connected to the slide rail 4. A threaded hole 6 is installed at the center of the corresponding location of the sliding limit block 5.
[0025] When it is necessary to install the upper and lower components in a staggered manner, two sets of sliding limit blocks 5 can be removed, leaving only the two sets of opposing sliding limit blocks 5, which can easily achieve horizontal and lateral staggered telescopic adjustment of the upper and lower components.
[0026] Magnetic suction element 7 is located at the front and rear ends of threaded hole 6 and is inserted and connected to sliding limit block 5 at corresponding positions. Nail holes 8 are provided on both sides of the center between the top ends of adjacent magnetic suction elements 7. After the sliding limit block 5 is first added inside the slide rail 4 of the upper cable limit frame 2 and the lower cable tray mounting frame 3, the sliding limit block 5 can move along the slide rail 4. The sliding limit block 5 can be connected to the mounting wall or building surface through threaded hole 6, magnetic suction element 7, and nail holes 8, thereby enabling staggered installation of upper and lower layers of cable trays within a certain range. This allows for length adjustment to meet the needs of different length scenarios. Furthermore, multiple cable tray structures can be combined and installed using screws, making it suitable for a wide range of applications.
[0027] Please see Figure 2The upper cable limiting frame 2 and the lower cable tray mounting frame 3 are connected by slide rails 4 on all four sides. The upper cable limiting frame 2 has a longitudinally spaced mounting hole 9 at its top center. C-shaped brackets 15 are detachably inserted into the inner walls of both the upper cable limiting frame 2 and the lower cable tray mounting frame 3. The upper cable limiting frame 2 and the lower cable tray mounting frame 3 are connected by C-shaped brackets 15, which limit the movement of the upper and lower structures, facilitating stable handling. When staggered installation of the upper and lower layers is required, the C-shaped brackets 15 of the handling auxiliary structure can be removed. The sliding limiting block 5 can move in a circular motion along the slide rails 4 of the upper cable limiting frame 2 and the lower cable tray mounting frame 3. Compared to some slide rail structures that can only move back and forth, this structure offers greater adjustability and practicality.
[0028] Please see Figure 3 The sliding limit block 5 has a Z-shaped design, and its back side fits against the upper cable limit frame 2 and the lower cable tray mounting frame 3. The threaded hole 6, magnetic 7, and nail hole 8 are all located at the corresponding positions on the lower front side of the sliding limit block 5. The sliding limit block 5 can move by fitting against the outer wall of the upper cable limit frame 2 and the lower cable tray mounting frame 3.
[0029] Please see Figure 2 Each sliding limit block 5 has a longitudinally spaced limit hole 10 at its top center, which corresponds to the shape and position of the mounting hole 9. Each limit hole 10 has a longitudinally inserted limit post 11 inside its cavity. The limit post 11 can be inserted into the interior of the limit hole 10 and the mounting hole 9 of the sliding limit block 5.
[0030] Please see Figure 3 The top of the limiting post 11 is longitudinally grooved with anti-slip grooves around its four sides. The limiting post 11 is cylindrical in shape, and its bottom end passes through the limiting hole 10 and is inserted into the mounting hole 9. The lower part of the limiting post 11 passes through the limiting hole 10 and is inserted into the mounting hole 9, so that the sliding limiting block 5 is connected to the upper cable limiting frame 2, thereby preventing the sliding limiting block 5 from moving on the upper cable limiting frame 2 and the lower cable tray mounting frame 3. A telescopic double-headed rod 12 is installed at the center of the back of the sliding limiting block 5, and a compression spring 13 is sleeved on the surface of the telescopic end of the top and bottom of the telescopic double-headed rod 12. A sliding post 14 is installed at the telescopic end of the telescopic double-headed rod 12 and is inserted into the inner cavity of the corresponding slide rail 4, and fits tightly against the inner wall of the slide rail 4. The telescopic end of the telescopic double-headed rod 12, under the action of the compression spring 13, drives the corresponding sliding column 14 to extend outward and insert into the corresponding slide rail 4. The sliding limit block 5 slides on the slide rail 4 through the sliding column 14. At the same time, it is convenient to disassemble and replace the sliding limit block 5 with the slide rail 4. The sliding limit block 5 can be replaced.
[0031] This solution involves first installing a sliding limit block 5 inside the slide rail 4 between the upper cable limit frame 2 and the lower cable tray mounting frame 3. The sliding limit block 5 can then move along the slide rail 4. It can be connected to the wall or building surface via threaded holes 6 and magnetic attachments 7. Cables can be bound to the surfaces of the upper and lower structures, achieving the function of a cable tray. The telescopic end of the telescopic double-headed rod 12, under the action of the compression spring 13, drives the corresponding sliding column 14 to extend outward and insert into the corresponding slide rail 4. The sliding limit block 5 slides on the slide rail 4 via the sliding column 14, facilitating easy disassembly and replacement of the sliding limit block 5 and the slide rail 4. The upper cable limit frame 2 and the lower cable tray mounting frame 3 are connected by a C-shaped bracket 15, and the sliding limit block 5 can move in a circular motion along the slide rail 4 between the upper cable limit frame 2 and the lower cable tray mounting frame 3. The lower part of the limiting post 11 passes through the limiting hole 10 and is inserted into the mounting hole 9, so that the sliding limiting block 5 is connected to the upper cable limiting frame 2.
