A self-locking cable tray

Abstract

This utility model discloses a self-locking cable tray, comprising two symmetrical housings. A cover plate is provided on the top of each housing. Three identical hooks are fixedly connected to the front and back of the cover plate, and three identical fasteners are fixedly connected to the front and back of each housing. The hooks and fasteners are compatible. Multiple identical openings are provided on both the front and back of each housing. This utility model allows for cable tray docking via a connecting structure. By placing the two housings together and pushing the fixing rod, the fixing rod enters the inner cavity of the second fixing frame. At this time, the limiting plate is in contact with the first fixing frame. Rotating the torsion block causes the threaded rod to connect with the threaded sleeve, allowing the threaded rod to enter the inner cavity of the second fixing frame and engage with the fixing rod. This eliminates the need for users to use multiple bolts to fix the cable tray, improving the efficiency of cable tray docking.

A cover plate 2 is provided on the top of each housing 1. Three identical hooks 3 are fixedly connected to both the front and back of the cover plate 2. Three identical fasteners 4 are fixedly connected to both the front and back of each housing 1. The hooks 3 and fasteners 4 are adapted to each other. Multiple identical openings 5 ​​are provided on both the front and back of each housing 1. A fixing bracket 6 is bolted to both the front and back of each housing 1. A limiting groove 13 is provided on the front of the fixing bracket 6, adapting to the side of the fixing bracket 6's inner cavity away from the housing 1. Two symmetrical reinforcing plates 14 are fixedly connected to the top and bottom of both the fixing bracket 6 and the second fixing bracket 8. The reinforcing plates 14 are triangular. The reinforcement plates 14 are designed to... When the first fixing frame 6 and the second fixing frame 8 are fixed to the housing 1 by the fixing rod 7, the reinforcing plate 14 will support the first fixing frame 6 and the second fixing frame 8 to prevent the first fixing frame 6 or the second fixing frame 8 from being squeezed and deformed, thus increasing the firmness of the first fixing frame 6 and the second fixing frame 8. The inner cavity of the first fixing frame 6 is slidably connected to the fixing rod 7. The front and back of the housing 1 are fixedly installed with the second fixing frame 8 by bolts.

The inner cavity of the threaded sleeve 9 is threadedly connected to the threaded rod 10. The front of the threaded rod 10 is fixedly connected to the torsion block 11. The threaded rod 10 passes through the inner cavity of the second fixing frame 8 and engages with the fixing rod 7. The front of the fixing rod 7 is fixedly connected to the limit plate 12. Example 2

[0022] Figure 1-4 This invention illustrates a self-locking cable tray according to an embodiment of the present invention. It includes two symmetrical housings 1. A cover plate 2 is provided on the top of each housing 1. Three identical hooks 3 are fixedly connected to both the front and back of the cover plate 2. Three identical fasteners 4 are fixedly connected to both the front and back of each housing 1. The hooks 3 and fasteners 4 are compatible. Multiple identical openings 5 ​​are provided on both the front and back of each housing 1. The openings 5 ​​are elongated. A fixing rod 7 is a hollow square tube. Two symmetrical torsion bars are fixedly connected to the surface of a torsion block 11. A fixing bracket 6 is bolted to both the front and back of each housing 1. The inner... The cavity is slidably connected to a fixing rod 7. The top and bottom of the fixing rod 7 are respectively attached to the top and bottom of the fixing frame 6 and the fixing frame 8. The limiting plate 12 is attached to the fixing frame 6. The front and back of the housing 1 are fixedly installed with the fixing frame 8 by bolts. The fixing rod 7 is adapted to the fixing frame 8.

The front of the threaded rod 10 is fixedly connected to a torsion block 11. The threaded rod 10 passes through the inner cavity of the fixing frame 8 and engages with the fixing rod 7. The front of the fixing rod 7 is fixedly connected to a limiting plate 12.

[0023] Working principle: When using this utility model, the user places two symmetrical shells 1 together and pushes the fixing rod 7, causing the fixing rod 7 to enter the inner cavity of the second fixing frame 8. At this time, the limiting plate 12 will fit against the first fixing frame 6. Rotating the torsion block 11 causes the threaded rod 10 and the threaded sleeve 9 to move threadedly, so that the threaded rod 10 enters the inner cavity of the second fixing frame 8 and engages with the fixing rod 7, thereby limiting the fixing rod 7 and fixing the two symmetrical shells 1. This avoids the need for the user to use multiple bolts to fix the cable tray, improving the efficiency of cable tray connection. With the setting of the reinforcing plate 14, when the first fixing frame 6 and the second fixing frame 8 are fixed to the shells 1 by the fixing rod 7, the reinforcing plate 14 will support the first fixing frame 6 and the second fixing frame 8, preventing the first fixing frame 6 or the second fixing frame 8 from being squeezed and deformed, and increasing the firmness of the first fixing frame 6 and the second fixing frame 8.

[0024] In summary, this self-locking cable tray, by placing the two housings 1 together and pushing the fixing rod 7, allows the fixing rod 7 to enter the inner cavity of the second fixing frame 8. At this time, the limiting plate 12 is in contact with the first fixing frame 6. Rotating the torsion block 11 causes the threaded rod 10 to be threadedly connected to the threaded sleeve 9, so that the threaded rod 10 enters the inner cavity of the second fixing frame 8 and engages with the fixing rod 7. This allows the cable tray to be connected through the connection structure, avoiding the need for users to use multiple bolts to fix the cable tray, thus improving the efficiency of cable tray connection.
