[0017] 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.

[0018] This utility model provides, for example Figure 1-4 The cable tray connection structure shown includes a cable tray 1, which is at least two sets. At the close ends of the two sets of cable trays 1, a hook assembly 2 and a plate assembly 3 are respectively fixedly installed. Both the hook assembly 2 and the plate assembly 3 are provided with bolts 4, and one end of the bolts 4 extends to the cable tray 1. The hook assembly 2 and the plate assembly 3 are two sets, symmetrically arranged. When fixing the two sets of cable trays 1, the hook assembly 2 is installed on one of the cable trays 1 with bolts 4, and the plate assembly 3 is fixed on the adjacent cable tray 1 with bolts 4. After the hook assembly 2 and the plate assembly 3 are installed, the sliding connecting plate 11 can be used to drive the locking plate 12 to move, so that the locking plate 12 is connected to the locking block 7, and the pin 16 is moved into the fixing port 17, so that the position of the connecting plate 11 is fixed. The locking plate 12 is a U-shaped plate rotated 90 degrees. The U-shaped locking plate 12 is connected to the locking block 7 to achieve the purpose of connecting the hook assembly 2 and the plate assembly 3. When it is necessary to disconnect the connection between the two cable trays 1, the pin 16 can be pulled upward to make the connecting plate 11 slide, and the push rod 15 can be slid from the end of the slide groove away from the fixing seat to the end close to the fixing seat. In this way, the locking plate 11 can be fixed. Pushing block 13 to opposite sides simultaneously slides connecting plate 11 closer to fixed plate 10, so that when block 13 slides to contact block 7, it presses one end of block 7 downward and offsets it from the locking block until block 7 and locking plate 12 are completely offset. Then push rod 15 can be released, and the two blocks 13 will move closer to each other under the action of tension spring 19, and push rod 15 will slide from one end of the groove to the initial end. After connecting plate 11 is completely slid to a state parallel to one end of fixed plate 10, it can be connected to another fixing port 17 through pin 16 to fix the position of connecting plate 11. Through the above operation, the operation steps of connecting cable tray 1 are reduced. Moreover, according to the needs of use, the hooks and hook assemblies 2 can be fixed on cable tray 1 respectively to realize the installation of multiple cable trays 1. The operation is simple and easy to use, which is conducive to improving the installation of cable tray 1 and the fixing of cables.

[0019] Specifically, the hook assembly 2 includes a base plate 5, an extension seat 6, and a locking block 7. The base plate 5 is fixedly connected to the outer wall of the cable tray 1. The extension seat 6 is fixedly mounted on the base plate 5, and a groove 8 is provided on the extension seat 6. The locking block 7 is rotatably mounted in the groove 8. The outer wall of one side of the locking block 7 is movably connected to the inner wall of the groove 8, and a spring 9 is provided between the groove 8 and the locking block 7. (See attached diagram.) Figure 2As shown, the base plate 5 is fixed to the cable tray 1 by bolts 4. An extension seat 6 fixedly connected to the base plate 5 has a groove 8. A locking block 7 rotates within the groove 8. The normal state of the locking block 7 is: one end is inside the groove 8, and the other end is outside the groove 8. A spring 9 is located on the lower outer wall outside the groove 8. Both ends of the spring 9 are fixedly connected to the groove 8 and the locking block 7, respectively. To ensure the normal use of the spring 9, a rod for sliding is also provided on the locking block 7. The spring 9 is sleeved on the outside of the rod. A slot is provided in the groove 8 to provide space for the rod to move. The slot can be rectangular, trapezoidal, etc., allowing the rod to move freely. The locking block 7 has an opening that makes arc-shaped movement, and the rod body is movably connected to the inner wall of the slot. The spring 9 is located at the upper end of the slot. During use, the state of the locking block 7 is affected by the movement of the connecting plate 11. For example, when the connecting plate 11 drives the locking plate 12 to move, when it slides to a certain position, the locking plate 12 will contact the outer wall on the upper side of the locking block 7. Under the force of the locking plate 12, the spring 9 is forced to contract, and one end of the locking block 7 rotates downward at a certain angle, so that the locking plate 12 can slide smoothly to the side closer to the bottom plate 5 and separate from the locking block 7. The spring 9 will push the locking block 7 upward in the same way to facilitate subsequent connection with the locking plate 12.

[0020] Specifically, the clamping plate assembly 3 includes a fixing plate 10 and a connecting plate 11. The fixing plate 10 is fixedly connected to the outer wall of the cable tray 1. The connecting plate 11 is slidably mounted on the fixing plate 10. A snap-fit ​​plate 12 is provided on the connecting plate 11, and the snap-fit ​​plate 12 is movably connected to the clamping block 7. A stop block 13 is movably mounted on the lower outer wall of the connecting plate 11. A guide groove 14 is provided on the lower outer wall of the connecting plate 11, and the stop block 13 is slidably mounted in the guide groove 14. A push rod 15 is provided on the connecting plate 11, and a sliding groove for installing the push rod 15 is opened on the connecting plate 11. The push rod 15 is movably connected to the outer wall of one side of the stop block 13. A pin 16 is provided on the connecting plate 11, and a fixing opening 17 is opened on the fixing plate 10. One end of the pin 16 is movably mounted in the fixing opening 17. (See attached diagram.) Figure 3 , 4As shown, the fixing plate 10 is provided with a slot for sliding the connecting plate 11 and a fixing port 17 for the connecting pin 16. When connecting the hook assembly 2, the connecting plate 11 can be slid to the upper side of the base plate 5 by sliding the connecting plate 11, and then slid until it is in contact with the outer wall of the upper side of the block 7. After that, it is moved to its front side. As the block 7 rebounds upward under the drive of the spring 9, the connecting plate 11 can be pulled in the opposite direction until it is connected with the locking plate 12. Then, the pin 16 is moved into the fixing port 17 to fix the position of the connecting plate 11, so as to connect the two cable trays 1. A push rod 15 is provided on the connecting plate 11. One end of the push rod 15 extends to the lower side of the connecting plate 11 through a sliding groove. When it is necessary to disconnect the connection of the two cable trays 1, the pin 16 is first pulled upward and disengaged from the fixing port 17, and the push rod 15 drives the abutment block. Push 13 to one side, so that the abutment 13 gradually moves away from both sides under the force of the oblique wall of the push rod 15. After the push rod 15 slides to the other end of the groove, the abutment 13 is located on the upper side of the locking block. Then, move the connecting plate 11 closer to the fixed plate 10. At this time, the abutment will gradually connect with the locking block 7. As the connecting plate 11 moves, the abutment 13 presses down on the locking block 7 until the locking plate 12 moves smoothly to the other side of the locking block 7. At this time, the push rod 15 can be released, so that the abutment 13 is reset under the action of the tension spring 19. Then, slide the connecting plate 11 to the other end of the slot provided on the fixed plate 10, and insert the pin 16 into the fixing port 17 to fix the connecting plate 11. Through the above operation, the installation steps of the cable tray 1 are simplified, so as to facilitate the installation of the cable tray 1 and the fixing of the cable, and facilitate its use.

[0021] The connecting plate 11 has an installation port, and the pin 16 is slidably installed in the installation port. A rectangular block is provided on the pin 16, and a rectangular opening that mates with the rectangular block is provided on the installation port. A tension spring 18 is provided in the installation port. After the connecting plate 11 slides to the target position, the pin 16 can be rotated to slide through the rectangular opening into the installation port. After sliding a certain distance, the rectangular opening in the installation port engages with the rectangular block, thus fixing the position of the fixing block. In subsequent disassembly, the pin 16 is pulled upward to the outside of the installation port and rotated to make the rectangular block of the pin 16 offset from the rectangular opening. In this way, the pin 16 will be fixed under the obstruction of the rectangular block, and one end of it will be disengaged from the fixing port 17 to facilitate the movement of the connecting plate 11.
