[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a general steel cable tray based on modular design as shown in Figure 1 - Figure 6 The steel cable tray is mainly used for cable protection, including a cable tray body 2. The cable tray body 2 is a steel cable tray, which is a prior art and will not be described in detail herein. A plurality of cable tray bodies 2 form a cable tray module 1, and the cable is protected through the cable tray body 2. Support rods 3 are fixedly provided on both inner walls of the cable tray body 2. Rectangular holes are opened inside the support rods 3, and elastic plates 13 are fixedly provided inside the rectangular holes. A connecting plate 5 is fixedly provided at the upper end of the elastic plate 13. One side of the connecting plate 5 is fixedly connected to the end of a limiting block 6. Guide plates 12 are fixedly provided on both inner walls at both ends of the cable tray body 2. The support rods 3 are in movable contact with the guide plates 12, and the cross-section of the guide plates 12 is concave.

[0027] After an operator fixes one cable tray body 2, then moves another cable tray body 2 towards the fixed cable tray body 2 to align the support rods 3 with the guide plates 12, which is convenient for initially assisting the installation of the support rods 3 during installation.

[0028] A plurality of limiting blocks 6 are movably provided at the end of the support rod 3 away from the connecting sleeve 4. The edge of the limiting block 6 is provided with an inclined surface. A plurality of limiting holes 7 are opened at one end of the connecting sleeve 4. The limiting blocks 6 are movable inside the corresponding limiting holes 7. The number of unlocking rods 8 is equal to that of the limiting holes 7 and the limiting blocks 6. A connecting sleeve 4 for connecting the corresponding support rods 3 is fixedly provided at the end of the support rod 3 inside the cable tray body 2.

[0029] The movement of the support rod 3 drives the movement of the elastic plate 13 and the connecting plate 5. The connecting plate 5 drives the plurality of limiting blocks 6 to move. The limiting blocks 6 contact the corresponding connecting sleeve 4, so that the connecting sleeve 4 contacts the limiting blocks 6. The limiting blocks 6 enter the limiting holes 7 on the connecting sleeve 4 through their own inclined surfaces, completing the connection of the two cable tray bodies 2.

[0030] Through the setting of the limiting blocks 6 and their own inclined surfaces, when connecting the two cable tray bodies 2, the installation can be quickly completed, reducing the installation time.

[0031] Through the arrangement of the support rod 3, when installing two bridge body 2, the overall strength of the side of the bridge body 2 can be increased through the support rod 3, the anti-collision ability of the bridge body 2 can be improved, and the anti-deformation ability can be improved.

[0032] Sliding plates 9 are movably arranged on the inner walls at both ends of the bridge body 2. A plurality of unlocking rods 8 are fixedly arranged at the lower ends of the sliding plates 9. Two rectangular grooves 10 are penetrated and opened on the inner walls at both ends of the bridge body 2. T-shaped plates 11 are slidably arranged inside the rectangular grooves 10. One end of the T-shaped plate 11 is fixedly connected to one end of the sliding plate 9. One end of the support rod 3 extends out of the bridge body 2. Through the obvious feature of the extended support rod 3, when installing the bridge body 2, the installation direction of the bridge body 2 can be quickly distinguished;

[0033] When the bridge body 2 needs to be removed, only need to press the sliding plate 9. Under the limitation of the rectangular groove 10 and the T-shaped plate 11, the sliding plate 9 can only move up and down. The sliding plate 9 drives a plurality of unlocking rods 8. The unlocking rods 8 enter the limiting holes 7. By the unlocking rods 8 squeezing the limiting blocks 6, the limiting blocks 6 squeeze the elastic plates 13 to complete the connection between the support rod 3 and the connecting sleeve 4, and complete the disassembly of the two bridge bodies 2.
