Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray connector that can be quickly installed. Background Technology

[0002] Cable trays are essential facilities in electrical engineering used to support and protect cables. They are widely used in buildings, factories, computer rooms, and other settings, and require connectors to ensure stable assembly between the tray body and the cover plate. As electrical systems become increasingly complex, the industry demands greater ease of installation for cable trays. Quick-installation cable tray connectors have emerged to meet this need. These connectors are adaptable to various common cable laying environments, helping to ensure neat cable arrangement and safe operation, and providing fundamental support for electrical engineering construction.

[0003] Utility model patent CN222673816U discloses a powder-coated cable tray. This powder-coated cable tray includes a tray body with openings at both ends and one side for cable placement; a cover plate positioned over the opening on one side of the tray body; several plastic fasteners integrally connected to the tray body; a deformation gap configured to cooperate with the plastic fasteners to cause plastic deformation, thereby fastening and fixing the cover plate to the tray body; and a limiting structure positioned between the cover plate and the plastic fasteners to restrict their relative movement along the length of the tray body. This powder-coated cable tray is easy to operate and has low production costs, thus ensuring convenient maintenance.

[0004] This powder-coated cable tray has two main drawbacks. First, installation relies on plastic deformation. The cover plate must first be aligned with the insertion gap and inserted, and then the plastic limiting section of the plastic fastener must be manually bent to fit into the limiting hole. Each connection requires a separate "insertion-bending" operation, and the plastic deformation operation requires precise control of the force. It cannot be quickly fixed by simply pushing or using threaded connections. Second, the plastic fastener relies on plastic deformation for fixation, and it is prone to irreversible deformation after bending. If the cover plate needs to be removed, the plastic fastener may be damaged. When reinstalling, a new plastic fastener needs to be replaced. It cannot be quickly reassembled using the original structure, further reducing installation efficiency. In view of this, we propose a cable tray connector that can be installed quickly. Utility Model Content

[0005] The purpose of this invention is to provide a cable tray connector that can be installed quickly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A quick-installable cable tray connector includes a cable tray body and a cover plate disposed at the top of the cable tray body. The top of the cable tray body has protruding edges on both the left and right sides. The bottom of the cover plate has inserts fixed on both the left and right sides. The bottom end of the insert passes through the protruding edges and is fitted with a connector. The connector is used to install the cable tray body to the bottom of the cover plate. The connector includes a sleeve block and two locking components symmetrically arranged at the left and right ends of the sleeve block. The sleeve block has a slot, and the bottom end of the insert block is inserted into the slot. The locking component includes a locking block that is laterally inserted into the sleeve block and slidably connected to the sleeve block, and a rotating column that passes through the locking block and is rotatably connected to the locking block. When the insert block is inserted into the slot, the locking block can be inserted into the insert block by pushing the two locking components on both sides inward. The ends of the two rotating columns can be threaded together when they are close to each other.

[0007] Preferably, the protruding edge has several through holes, the positions of the holes correspond to the positions of the plug, and the bottom end of the plug passes through the holes; This setting guides the insert block to precisely penetrate the protruding edge, providing a basis for the alignment of the cable tray body and the cover plate, and preventing the insert block from shifting during installation.

[0008] Preferably, the top surface of the slot and the end surface near the main body of the cable tray are both open. When the main body of the cable tray is placed against the bottom of the cover plate and the insert is made to pass through the insertion hole, the bottom end of the insert can be inserted into the slot from the opening of the slot by moving the sleeve block close to the bottom end of the insert block, and the top surface of the sleeve block abuts against the bottom surface of the protrusion. In this design, the open structure facilitates the docking of the sleeve block and the insert block, and the sleeve block abuts against the convex edge so that the sleeve block and the cover plate can clamp the convex edge.

[0009] Preferably, the sleeve block has a rectangular cross-section through groove that runs horizontally through the sleeve block and is connected to the slot. The locking block is fitted inside the through groove and can move horizontally along the through groove. Preferably, a baffle is fixed at both ends of the through groove. The baffle has a rectangular frame structure and is used to prevent the locking block from coming out of the through groove. In these two settings, the through slot provides lateral movement space for the lock block and connects to the slot, making it easy for the lock block to be inserted into the insert block; the retaining frame can limit the range of motion of the lock block and prevent the lock block from dislodging from the through slot, which would cause the connection to fail.

[0010] Preferably, the lock block has a sleeve hole opened laterally, the rotating column is sleeved in the sleeve hole, the outer end face of the lock block has an insert hole, the insert hole is connected to the sleeve hole, a limiting pin is embedded in the insert hole, and an annular groove is opened on the outer peripheral surface of the rotating column, the end of the limiting pin extends into the annular groove. In this configuration, the sleeve hole provides installation space for the rotating column, and the limit pin and the ring groove cooperate to restrict the axial movement of the rotating column, ensuring that the rotating column only rotates around its own axis and does not disengage from the locking block.

[0011] Preferably, the end of the rotating post on one of the locking components is provided with a threaded post, and the end of the rotating post on the other locking component is provided with a threaded hole, so that the threaded post can be screwed into the threaded hole by approaching the two rotating posts; Preferably, the first end of the rotating column extends outward from the sleeve block and is fixed with a handle, which can drive the rotating column to rotate by rotating the handle; In these two settings, the threaded post and the threaded hole can quickly fix the two rotating posts, which is convenient for subsequent disassembly; the handle is easy for the operator to hold and rotate, reducing the difficulty of operating the rotating posts and requiring no additional tools.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This quick-installable cable tray connector uses an assembly logic of inserting a plug through the insertion hole, inserting it into the slot of the sleeve block, pushing the locking block into the plug, and threaded connection to the rotating column. It can be fixed simply by pushing the locking component and turning the handle, making the operation process simpler. 2. This quick-installable cable tray connector allows the locking assembly to lock and unlock via a sliding connection where the locking block moves along the through groove and a rotating connection where the rotating column rotates with the locking block. During disassembly, simply rotate the rotating column in the opposite direction to separate the threaded connection and pull the locking block outward to remove the connector. There is no irreversible deformation in any of the structures, allowing for repeated installations and making secondary installations more convenient, further improving overall installation efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figures 1-6 The cable tray connector is quick-installable and includes a cable tray body 100 and a cover plate 200 at the top of the cable tray body 100. Both the cable tray body 100 and the cover plate 200 are made of cold-rolled steel plate with a powder-coated surface to improve corrosion resistance. The left and right edges of the top of the cable tray body 100 are provided with protruding edges 110, which are integrally stamped with the cable tray body 100, enhancing the structural strength of the top edge and preventing edge deformation during installation. Insert blocks 210 are fixed to the left and right edges of the bottom surface of the cover plate 200. The insert blocks 210 have transversely openable pin holes 211 and are made of galvanized steel plate. The material is fixed to the cover plate 200 by welding, and the weld is ground to ensure connection stability. Several through holes 120 are opened on the protruding edge 110. The position of the holes 120 corresponds to the position of the plug 210, which can ensure that the plug 210 accurately passes through the protruding edge 110. The bottom end of the plug 210 passes through the holes 120 and extends downward through the protruding edge 110 and is equipped with a connector 300. The connector 300 is used to install the cable tray body 100 to the bottom of the cover plate 200. Through the cooperation of the plug 210 and the connector 300, the initial positioning of the cable tray body 100 and the cover plate 200 can be achieved, providing a foundation for subsequent fixing.

[0016] like Figures 4-6As shown, in this utility model, the connector 300 includes a sleeve block 310 and two locking components 320 symmetrically arranged at the left and right ends of the sleeve block 310. The sleeve block 310 is made of aluminum alloy, which is lightweight and has high hardness, reducing the overall weight of the connector while ensuring load-bearing capacity. A slot 311 is provided in the sleeve block 310. The size of the slot 311 is adapted to the cross-sectional size of the insert 210, allowing the bottom end of the insert 210 to be stably inserted into the slot 311, preventing the insert 210 from shaking in the slot 311. The top surface of the slot 311 and the area near the bridge The end faces of the frame body 100 are all open. This open structure facilitates the docking of the sleeve block 310 with the insert block 210 from the side and bottom, reducing operational obstacles during installation. The locking assembly 320 includes a locking block 321 that is laterally inserted into the sleeve block 310 and slidably connected to the sleeve block 310, and a rotating column 322 that passes through the locking block 321 and is rotatably connected to the locking block 321. The locking block 321 is made of stainless steel, which can improve wear resistance and extend the service life of repeated sliding. The surface of the rotating column 322 is chrome-plated, which can reduce the coefficient of friction during rotation and make the rotation operation smoother.

[0017] Specifically, when the cable tray body 100 is placed against the bottom of the cover plate 200 and the insert 210 passes through the socket 120, the bottom end of the insert 210 is inserted into the slot 311 from the opening of the slot 311 by moving the sleeve 310 closer to the bottom end of the insert 210, and the top surface of the sleeve 310 abuts against the bottom surface of the protrusion 110. After the sleeve 310 abuts against the protrusion 110, it can axially limit the insert 210 and prevent the insert 210 from coming out of the socket 120 upwards; when the insert 210 is inserted into the socket 120... After the slot 311 is inserted, the two locking components 320 on both sides can be pushed inward to insert the locking block 321 into the insert block 210 until the end of the locking block 321 is inserted into the pin hole 211. After the locking block 321 is inserted into the insert block 210, it can restrict the lateral relative movement between the insert block 210 and the sleeve block 310, further improving the connection stability. The ends of the two rotating columns 322 can be threaded together when they are close to each other. The threaded connection structure can fix the locking components 320 on both sides and prevent the locking block 321 from sliding outward during use.

[0018] like Figure 4As shown, furthermore, a rectangular through groove 312 is laterally formed on the sleeve block 310. The cross-sectional dimensions of the through groove 312 match the cross-sectional dimensions of the locking block 321, ensuring that the locking block 321 slides smoothly along the through groove 312. The through groove 312 passes through the sleeve block 310 laterally and is connected to the slot 311. This connection structure provides a channel for the locking block 321 to be inserted into the insert block 210. The locking block 321 is fitted in the through groove 312 and can move laterally along the through groove 312. A retaining frame 313 is fixed at both ends of the through groove 312. The retaining frame 313 is made of engineering plastic and is fixed to the sleeve block 310 by a snap-fit ​​method, making it easy to install and disassemble. The retaining frame 313 has a rectangular frame structure and is used to prevent the locking block 321 from coming out of the through groove 312, thus preventing the locking block 321 from coming out of the through groove 312 during sliding and causing connection failure.

[0019] like Figure 4 and Figure 6 As shown, in addition, a sleeve hole 3211 is provided laterally on the locking block 321. The inner wall of the sleeve hole 3211 is polished to reduce friction with the rotating column 322. The rotating column 322 is fitted into the sleeve hole 3211. An insert hole 3212 is provided on the outer end face of the locking block 321. The insert hole 3212 is connected to the sleeve hole 3211. A limit pin 3213 is embedded in the insert hole 3212. The limit pin 3213 is made of high-strength steel and has good shear resistance. An annular groove 3221 is provided on the outer circumferential surface of the rotating column 322. The width of the annular groove 3221 is adapted to the diameter of the end of the limit pin 3213. The end of the limit pin 3213 extends into the annular groove 3221. This structure can restrict the axial movement of the rotating column 322, ensuring that the rotating column 322 can only rotate around its own axis and does not disengage from the locking block 321.

[0020] like Figure 5 and Figure 6 As shown, it is worth noting that the end of the rotating post 322 on one of the locking components 320 is provided with a threaded post 3222, and the end of the rotating post 322 on the other locking component 320 is provided with a threaded hole. The threaded post 3222 and the threaded hole are matched in thread specification. By approaching the two rotating posts 322, the threaded post 3222 can be screwed into the threaded hole. The threaded connection can realize the quick fixation of the two rotating posts 322, and at the same time facilitates the loosening and separation by reverse screwing during subsequent disassembly.

[0021] like Figures 3-6As shown, it is worth noting that the first end of the rotating column 322 extends outward from the sleeve block 310 and is fixed with a handle 3223. The handle 3223 is made of ABS plastic and has anti-slip texture on the surface, which can increase the friction between the hand and the handle 3223, making it easier for the operator to hold and rotate. By rotating the handle 3223, the handle 3223 can drive the rotating column 322 to rotate, reducing the difficulty of operating the rotating column 322 and completing the rotation operation without the need for additional tools.

[0022] In this embodiment, the quick-installable cable tray connector is used as follows: First, the cable tray body 100 is placed against the bottom of the cover plate 200, aligning the insert 210 on the bottom surface of the cover plate 200 with the insertion hole 120 on the protruding edge 110, and the bottom end of the insert 210 is passed through the insertion hole 120, completing the initial alignment of the cable tray body 100 and the cover plate 200; then, the connector 300 is taken, with the opening of the slot 311 of the sleeve 310 facing the bottom end of the insert 210, and the sleeve 310 is moved closer to the insert 210 until the bottom end of the insert 210 is inserted into the slot 311, and the top surface of the sleeve 310 abuts against the bottom surface of the protruding edge 110, realizing the initial assembly of the connector 300 and the insert 210; Then, push the locking components 320 at both ends of the sleeve block 310 inward, so that the locking block 321 slides laterally along the through groove 312 and is inserted into the pin hole 211 in the insert block 210. At this time, the limiting pin 3213 moves synchronously with the locking block 321 in the annular groove 3221 of the rotating column 322, restricting the axial position of the rotating column 322. Finally, hold the handle 3223 at the head end of the two rotating columns 322, and rotate the handle 3223 to drive the rotating column 322 to rotate, so that the threaded post 3222 at the end of one rotating column 322 is screwed into the threaded hole at the end of the other rotating column 322, completing the fixation of the two rotating columns 322, thereby realizing the stable connection between the cable tray body 100 and the cover plate 200.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
