Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and in particular to a cable tray with a cabling structure and a ring network. Background Technology

[0002] Cable trays, as an important support structure for cable laying, are widely used in construction, industry and other fields. Different fasteners are required for cables of different sizes, which makes the operation cumbersome. The self-adaptive locking force is insufficient, and it is easy to apply uneven pressure to cables of different diameters. This can easily result in insufficient fastening force for thin cables and damage to thick cables, making it impossible to achieve stable fixation of cables of various specifications.

[0003] A search revealed Chinese patent documents (authorization announcement number CN220066733U), indicating that this utility model relates to the field of cable tray technology. It discloses a cable tray comprising a main body, legs mounted at the bottom of the main body, and horizontal partitions snapped onto the inner wall of the main body. Vertical partitions are snapped onto both the horizontal partitions and the bottom of the inner cavity of the main body. Several rows of connecting brackets are evenly spaced from top to bottom on opposite inner walls of the main body. This structure fully utilizes the space of the main body, allowing it to accommodate various cable arrangements, thus improving its applicability. While the device meets basic usage requirements, its self-adaptive locking force is insufficient, leading to uneven pressure on cables of different diameters. This can result in insufficient fastening force for thin cables and damage to thick cables, failing to achieve stable fixation of multiple cable specifications. Utility Model Content

[0004] The purpose of this invention is to provide a cabling structure and a ring network cable tray to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable tray structure and a ring network cable tray, including a ring tray plate for placing cables and cables, wherein a hollow column for limiting rotation is installed on the vertical inner wall of the ring tray plate. The hollow column has a circular rotating groove inside, and a rotating column is rotatably connected inside the circular rotating groove. Both ends of the rotating column are connected to rotating rods. Two spring-loaded springs are installed inside the circular rotating groove. One end of each spring is connected to the outer periphery of the two rotating rods, and the other end of each spring is connected to the inner wall of the hollow column. A limiting plate is installed at the end of the rotating rod away from the rotating column to limit the rotation of the rotating rod and the rotating column. A compression locking plate is connected to the outer periphery of the rotating column, and a limiting groove for the rotation of the compression locking plate is provided on the surface of the hollow column.

[0006] Preferably, the top of the compression locking plate is equipped with a multi-circular hollow block, and the interior of the multi-circular hollow block is provided with multi-circular grooves for limiting displacement.

[0007] Preferably, the interior of the multi-circular groove is connected to a plurality of compression springs for adaptive pressure adjustment, and the ends of the plurality of compression springs are connected to limit moving plates, which are slidably disposed inside the multi-circular groove.

[0008] Preferably, a round-headed extrusion post for extruding the cable is installed on the side of the limiting moving plate away from the extrusion spring, and the round-headed extrusion post completely penetrates the interior of the extrusion locking plate.

[0009] Preferably, the bottom of the annular bridge plate is rotatably connected to a threaded post for adjustment, and the end of the threaded post is rotatably mounted with a locking hook plate for engaging and locking with the end of the compression locking plate, and the end of the threaded post is rotatably disposed inside the locking hook plate.

[0010] Preferably, the inner bottom wall of the annular cable tray plate is provided with a cable trough for laying and placing cables, and the bottom of the cable trough is provided with an observation groove for observing the cable locking status.

[0011] Preferably, the top of the annular cable tray is fitted with a cover plate for protecting the cables inside the annular cable tray.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This cable tray structure and ring network cable tray benefit from the structure of the round-headed extrusion column. The extrusion springs in the multi-circular grooves are connected to the round-headed extrusion column through the limiting moving plate. When cables of different sizes are extruded, the round-headed extrusion column can drive the limiting moving plate to slide in the multi-circular groove, so that the extrusion springs can adapt to the expansion and contraction, ensuring that appropriate pressure is applied to cables of different diameters. This avoids insufficient clamping force for thin cables and ensures that thick cables are clamped, thus achieving stable fixation of cables of various specifications.

[0013] This cable tray structure and ring network utilize a compression locking plate. A spring provides initial tension, bringing the compression locking plate into contact with the locking hook plate and creating initial compression. Rotating the threaded column pulls the compression locking plate through the locking hook plate, causing the spring to deform secondary and adjust the pressure. This dual-spring design allows for both rapid basic locking and precise adjustment of the compression force, balancing ease of operation and reliable fixation. Attached Figure Description

[0019] like Figures 1 to 5 The cable tray structure and ring network cable tray shown include a ring tray plate 1 for placing cables and cabling, characterized in that: a hollow column 2 for limiting rotation is installed on the vertical inner wall of the ring tray plate 1. The hollow column 2 has a circular rotating groove 202 inside, and a rotating column 205 is rotatably connected inside the circular rotating groove 202. Rotating rods 204 are connected to both ends of the rotating column 205. Two spring-loaded springs 203 are installed inside the circular rotating groove 202. One end of each spring-loaded spring 203 is connected to the outer periphery of the two rotating rods 204, and the other end of each spring-loaded spring 203 is connected to the inner wall of the hollow column 2. A limiting plate 206 is installed at the end of the rotating rod 204 away from the rotating column 205 to limit the rotation of the rotating rod 204 and the rotating column 205. A compression locking plate 3 is connected to the outer periphery of the rotating column 205. The surface of the hollow column 2 has a limiting groove 201 for compressing the rotation of the locking plate 3. The spring-loaded springs 203 are in a state of natural tension in the initial state, and their elastic force is transmitted through the rotating rods 204 and the rotating column 205. The clamping plate 3 is pressed down so that its hook-shaped end remains in contact with the locking hook plate 401 (not fully locked but in a close fit). At this time, there is a certain gap between the round-headed clamping column 304 and the cable trough 102, and the cable can be directly placed between them to complete the initial cable arrangement. When it is necessary to place or remove the cable, the clamping plate 3 is manually pulled upward to separate its hook-shaped end from the locking hook plate 401. During the separation process, the rotating column 205 rotates in the circular rotating groove 202 of the hollow column 2, which drives the rotating rods 204 at both ends to rotate synchronously, so that the spring spring 203 is twisted (elastic potential energy increases). The limiting plate 206 restricts the axial displacement of the rotating parts to ensure stability. At this time, the round-headed clamping column 304 is lifted with the clamping plate 3, and the gap between it and the cable trough 102 increases, which facilitates the placement and adjustment of the cable.

[0020] The top of the compression locking plate 3 is equipped with a multi-circular hollow block 301. The interior of the multi-circular hollow block 301 has a multi-circular groove 302 for limiting displacement. Multiple compression springs 303 for adaptive pressure adjustment are connected inside the multi-circular groove 302. Each end of the compression springs 303 is connected to a limit moving plate 305, which is slidably disposed inside the multi-circular groove 302. A round-headed compression post 304 for compressing cables is installed on the side of the limit moving plate 305 away from the compression springs 303, and the round-headed compression post 304 completely penetrates the interior of the compression locking plate 3. After the cable is placed in place, the compression locking plate 3 is released, and the spring 203 releases its elastic potential energy (returning to its initial state), causing the rotating column 205 to rotate in the opposite direction, so that the hook-shaped end of the compression locking plate 3 re-contacts the locking hook plate 401. At this time, the round-headed compression column 304 moves closer to the cable under the tension of the spring, and cooperates with the cable groove 102 to form a preliminary compression on the cable. By utilizing the elastic deformation of the compression spring 303 in the multi-circle groove 302 (the round-headed compression column 304 drives the limiting moving plate 305 to slide after being compressed), the preliminary adaptation and fixation of cables of different sizes is achieved.

[0021] The bottom of the annular cable tray plate 1 is rotatably connected to a threaded post 4 for adjustment. The end of the threaded post 4 is rotatably mounted with a locking hook plate 401 for engaging and locking with the end of the compression locking plate 3. The end of the threaded post 4 is rotatably located inside the locking hook plate 401. To increase the fixing force, the threaded post 4 at the bottom of the annular cable tray plate 1 is rotated. Because the threaded post 4 is threadedly connected to the cable tray plate and its end engages with the locking hook plate 401, the rotation of the threaded post 4 causes the locking hook plate 401 to move downwards. The locking hook plate 401 pulls down the hook of the compression locking plate 3. The rounded end (utilizing its slight deformation properties to achieve tight pulling) further presses down the compression locking plate 3. At this time, the spring 203 is slightly twisted a second time (the elastic potential energy increases slightly), the pressure of the rounded compression column 304 on the cable increases, and the compression of the compression spring 303 increases, ensuring that the pressure is transmitted evenly. If it is necessary to reduce the fixing force, the threaded column 4 is rotated in the opposite direction, the locking hook plate 401 moves upward, the compression locking plate 3 is slightly lifted under the action of the spring spring's rebound force, the pressure of the rounded compression column 304 on the cable is reduced, and the compression spring 303 relaxes.

[0022] The inner bottom wall of the annular cable tray plate 1 is provided with a cable trough 102 for cable routing and placement. The bottom of the cable trough 102 is provided with an observation slot 103 for observing the cable locking status. The top of the annular cable tray plate 1 is equipped with a cover plate 101 to protect the cables inside. The cable trough 102 standardizes the cable arrangement path. The bottom observation slot 103 allows for direct observation of the contact status between the round-headed extrusion column 304 and the cable, determining whether the fixation is reliable. When the top cover plate 101 is closed, it forms a closed space, protecting the cables from external environmental interference. The limiting groove 201 on the surface of the hollow column 2 restricts the rotation angle of the extrusion locking plate 3, preventing excessive rotation and damage to components. Together with the limiting disc 206, it forms a double rotation constraint, ensuring the structural stability. The multi-circular hollow block 3... The multi-circular groove 302 within 01 provides a precise sliding trajectory for the limiting moving plate 305, preventing the round-headed extrusion column 304 from shifting and ensuring that the extrusion points on the cable are always evenly distributed. After the cover plate 101 on the top of the annular cable tray plate 1 is closed, it forms a closed space with the cable trough 102, which not only prevents dust and water but also reduces the impact of external collisions on the fit between the round-headed extrusion column 304 and the cable. In addition, the threaded connection design between the threaded column 4 and the annular cable tray plate 1 makes the displacement adjustment of the locking hook plate 401 quantifiable. By controlling the number of rotations of the threaded column 4, the increase or decrease of the extrusion pressure can be controlled more precisely to meet the fixing needs in different scenarios. These detailed designs make the various components work together more closely, ensuring both ease of operation and improving the adaptability and reliability of fixing multiple specifications of cables.

[0023] To avoid the impact of environmental, maintenance, and material factors on the normal operation of the cable tray structure and the ring network cable tray, targeted measures need to be taken from multiple dimensions: Regarding environmental protection, for humid environments, a waterproof coating can be sprayed onto the inner wall of the ring tray plate 1 and the inner side of the cover plate 101. The observation slot 103 at the bottom of the cable trough 102 adopts a transparent waterproof sealing cover design to prevent moisture infiltration and subsequent component corrosion. For dusty locations, a rubber sealing strip is installed at the connection between the cover plate 101 and the ring tray plate 1 to reduce dust entry. Simultaneously, the internal dust accumulation should be checked regularly through the observation slot 103 and cleaned promptly. In high-temperature environments, high-temperature resistant silicone rubber is used to make the round-headed extrusion column 304 and the extrusion spring 303 to prevent the material from losing elasticity due to high-temperature aging. In low-temperature environments, the spring spring 203 uses alloy steel with excellent low-temperature toughness to prevent low-temperature brittle fracture and ensure stable tension. In addition, in scenarios with frequent vibration, damping pads can be installed at the connection between the hollow column 2 and the annular bridge plate 1 to reduce the impact of vibration on rotating components such as the rotating column 205 and the rotating rod 204, and to prevent loosening. For maintenance, a regular inspection plan should be established. Weekly, check the contact status between the round-headed extrusion column 304 and the cable through the observation slot 103 to ensure there is no looseness or excessive extrusion. Monthly, manually operate the extrusion locking plate 3 to check its smooth engagement with the locking hook plate 401; if jamming occurs, apply a small amount of lubricant to the contact area. Quarterly, rotate the threaded column 4 to test the extrusion pressure adjustment function, clean the thread surface to prevent rust and jamming. Annually, test the elasticity of the spring 203 and the extrusion spring 303; if elasticity degradation is found, replace with springs of the same specification. When replacing or adjusting the cable, fully unlock the extrusion locking plate 3 first to avoid forced pulling that could deform the hook end or bend the round-headed extrusion column 304. After operation, ensure all components are back in place. In terms of material selection, the annular bridge plate 1 and hollow column 2 are made of hot-dip galvanized steel to improve overall corrosion resistance; the rotating column 205 and rotating rod 204 are made of stainless steel to reduce wear and corrosion during rotation. The hook-shaped end of the compression locking plate 3 is made of spring steel with good elastic deformation capability, which ensures a tight fit with the locking hook plate 401 and avoids breakage after repeated deformation; the surface of the locking hook plate 401 is chrome-plated to enhance wear resistance. The multi-circular hollow block 301 is made of high-strength engineering plastic to reduce weight and avoid electrochemical corrosion from contact with metal parts; the limiting moving plate 305 is made of wear-resistant alloy material to extend the sliding life in the multi-circular groove 302. Through the above measures, environmental erosion can be effectively resisted, losses caused by improper maintenance can be reduced, material performance can be ensured to be stable, and the long-term normal operation of the structure can be guaranteed.

[0024] Working principle In the initial state of use, the spring 203 of this cable tray structure and ring network is under natural tension. The rotating rod 204 and rotating column 205 drive the compression locking plate 3, keeping its hook-shaped end in contact with the locking hook plate 401. A gap remains between the round-headed compression column 304 and the cable tray 102, allowing direct placement of cables. When removing or placing cables, the compression locking plate 3 is manually pulled up to separate it from the locking hook plate 401. The rotating column 205 rotates within the circular rotating groove 202 of the hollow column 2, causing the rotating rod 204 to twist the spring 203 (increasing its elastic potential energy). The limiting disc 206 restricts axial displacement, and the round-headed compression column 304... As the cable is lifted, the increased gap facilitates operation. After the cable is placed, the compression locking plate 3 is released, the spring 203 releases its energy and resets, causing the rotating column 205 to reverse, so that the end of the compression locking plate 3 re-contacts the locking hook plate 401. Under the action of the spring force, the round-headed compression column 304 cooperates with the cable trough 102 to initially compress the cable. The compression spring 303 in the multi-circular groove 302 adapts to different cable sizes through the sliding of the limiting moving plate 305. The compression pressure can be adjusted by rotating the threaded column 4: clockwise rotation pulls down the locking hook plate 401 to compress the locking plate 3, the spring 203 twists a second time, and the pressure of the round-headed compression column 304 increases; counterclockwise rotation decreases the pressure. The cable trough 102 standardizes cable arrangement, the observation groove 103 facilitates status monitoring, and the cover plate 101 provides protection, achieving stable cable fixation and management as a whole.
