[0011] Compared with the prior art, the beneficial effects of this utility model are: the cable tray with an anti-seismic structure for cable laying is reasonable and has the following advantages:

[0012] (1) This design facilitates the buffering and shock absorption of the cable tray body through the cooperation of the locking block, the first insertion hole, bolts, nuts, connecting block, slot, fixing plate, second insertion hole, air inlet, air outlet, and rubber block. The cable tray is designed to improve the seismic performance of the cable tray by setting a connecting block between the first and second cable tray bodies and opening C-shaped slots on both sides of the connecting block. Under vibration, the cooperation between the C-shaped slots and the locking block allows for a certain displacement, thereby absorbing and buffering the vibration energy and reducing the direct impact on the cable tray. In addition, the honeycomb rubber block filled in the connecting block further enhances the stability of the structure. The elasticity of the rubber can absorb vibration, reduce the vibration of the structure, and improve the overall stability of the cable tray. This design enables the cable tray to maintain its stability in harsh environments. Maintaining stable operation ensures the safe laying and normal use of cables. The cable tray's connecting blocks are equipped with air inlets and outlets on both sides, with one-way inlet and outlet valves controlling gas flow. This design optimizes the connection method, making the connection between the first and second cable tray bodies tighter and more stable. The fixing components include fixing plates and bolts; the cooperation between the second and first insertion holes ensures a firm connection. Furthermore, rubber pads on both sides of the connecting blocks prevent direct contact between the cable tray bodies and the connecting blocks, reducing wear and noise, and facilitating installation and maintenance. This design simplifies the installation process, improves installation efficiency, and also facilitates maintenance and repair, as the bolted connection components are easy to disassemble and replace. This optimized connection method not only improves the reliability of the cable tray but also reduces maintenance costs and labor intensity. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0021] Example 1:

[0022] A cable tray with an anti-seismic structure for cable laying includes a first cable tray body 100 and a second cable tray body 300. A connecting block 200 is provided between the first cable tray body 100 and the second cable tray body 300. The connecting block 200 has slots 201 on both sides, and the slots 201 are C-shaped. The first cable tray body 100 and the second cable tray body 300 have locking blocks 101 on both sides that cooperate with the slots 201. The connecting block 200 has an air inlet 204 on one side and an air outlet 205 on the other side. The first cable tray body 100, the second cable tray body 300 and the connecting block 200 are connected by a fixing component.

[0023] The fixing component includes fixing plates 202 fixedly disposed on both sides of the connecting block 200. Two second insertion holes 203 are symmetrically opened on the fixing plates 202. The first cable tray body 100 and the second cable tray body 300 are symmetrically provided with first insertion holes 102. Fixing members are inserted into the second insertion holes 203.

[0024] The fastener includes a bolt 103 inserted into the second insertion hole 203, and nuts 104 are provided at both ends of the bolt 103 to cooperate with it.

[0025] The connecting block 200 is filled with rubber blocks 206, and the rubber blocks 206 are honeycomb-shaped.

[0026] The air inlet 204 is equipped with a one-way air inlet valve, and the air outlet 205 is equipped with a one-way air outlet valve.

[0027] Rubber pads are provided on both sides of the connecting block 200 to prevent the first cable tray body 100 and the second cable tray body 300 from directly contacting the connecting block 200.

[0028] Working principle: In use, the first cable tray body 100 is attached to the connecting block 200, and the locking block 101 on the first cable tray body 100 is engaged with the locking groove 201 on the connecting block 200, thus completing the docking of the first cable tray body 100 and the connecting block 200. The second cable tray body 300 is also installed on the other side of the connecting block 200 in the same manner. The locking block 101 and the locking groove 201 ensure precise alignment between the docking blocks, reduce errors, and improve the assembly accuracy of the overall structure. At the same time, the cooperation between the locking block 101 and the locking groove 201 provides a mechanical lock. To increase structural stability and prevent displacement of the first cable tray body 100 and the second cable tray body 300 during use, rubber pads are provided on both sides of the connecting block 200 to prevent direct contact between the first cable tray body 100 and the second cable tray body 300 and the connecting block 200, reducing wear and extending the service life of the first cable tray body 100 and the second cable tray body 300. Simultaneously, the rubber pads can absorb and disperse energy generated by vibration or impact, reducing damage to the first cable tray body 100 and the second cable tray body 300. After docking, bolts 103 are inserted into the fixed position. The bolt 103 passes through the first insertion hole 102 and is fixed by the engagement of the nut 104, thus completing the installation. The bolt 103 provides additional tightening force, thereby enhancing the stability of the entire structure. When the first cable tray body 100 or the second cable tray body 300 is subjected to external force, the first cable tray body 100 or the second cable tray body 300 will compress the rubber block 206 set in the connecting block 200 under the action of the locking block 101. The rubber block 206 absorbs and disperses the energy generated by vibration. Since the rubber block 206 is honeycomb-shaped, The honeycomb-shaped rubber block 206 has higher elasticity, allowing it to better recover its original shape after being compressed, thus providing a continuous cushioning effect. The honeycomb structure can also increase internal air circulation. When compressed, the internal gas is expelled by the air outlet 205. When the force is removed, the external gas is introduced into the connecting block 200 by the air inlet 204, ensuring the stability of the cushioning effect. The rubber block 206 absorbs vibration force, and the cooperation between the rubber block 206 and the rubber pad reduces the damage caused by vibration force to the first cable tray body 100 or the second cable tray body 300.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
