[0027] Example

[0028] refer to Figure 1-Figure 7 , an improved cable tray with stable connection, including a cable tray body 1, the cable tray body 1 including a bottom plate 11 and side plates 12 arranged on both sides of the bottom plate 11, the top of the outer end surface of the side plate 12 is fixedly connected to a connecting plate 13 extending along the length direction of the side plate 12, a docking groove 131 is opened on the top end surface of one end of the connecting plate 13, a fixing component 14 is provided in the docking groove 131, and the other end of the connecting plate 13 is provided with a docking plate 132 that can be pressed into the docking groove 131 of the adjacent cable tray body 1.

[0029] Furthermore, an assembly groove 111 is provided on the inner side wall of one end of the bridge body 1 close to the docking groove 131, and a guide groove 121 is provided on the inner side wall of the side panel 12 in the assembly groove 111. An assembly frame 112 adapted to the assembly groove 111 is provided at the end port of the bridge body 1 close to the docking plate 132, and a guide plate 122 is provided on the outer side wall of the assembly frame 112 to match the guide groove 121. The guide plate 122 and the assembly frame 112 on the bridge body 1 are inserted into the guide groove 121 and the assembly groove 111 on the adjacent bridge body 1, so that the two bridge bodies 1 are initially fixedly connected.

[0030] Among them, the fixing assembly 14 includes a fixing block 141 arranged in the docking groove 131, and two oppositely arranged accommodating cavities 142 are opened inside the fixing block 141. A compression spring 143 is provided in the accommodating cavity 142, and one end of the compression spring 143 is fixedly connected to the inner wall of the accommodating cavity 142, and the other end of the compression spring 143 is fixedly connected to a locking rod 144, and the locking rod 144 extends to the outside of the fixing block 141 away from one end of the compression spring 143. The bottom of one end of the locking rod 144 located inside the accommodating cavity 142 is fixedly connected to a driving rod 145 extending to the outside of the accommodating cavity 142 and passing through the connecting plate 13.

[0031] Furthermore, a driving groove 133 for the driving rod 145 to move is formed on the connecting plate 13 , and the driving groove 133 is communicated with the accommodating cavity 142 .

[0032] Furthermore, a fixing groove 134 is provided on the bottom end surface of the docking plate 132 for the insertion of the fixing block 141, and locking grooves 135 are provided on the docking plates 132 on both sides of the fixing groove 134 for the insertion of the locking rod 144. Through the setting of the fixing component 14, the two bridge frame bodies 1 after splicing can be locked, so that the two bridge frame bodies 1 are firmly connected.

[0033] Furthermore, a number of evenly distributed reinforcement plates 113 are provided on the outer walls at both ends of the bridge body 1, and a U-shaped reinforcement frame 15 is slidably connected to the outer wall of one end of the bridge body 1 close to the assembly frame 112. A number of reinforcement grooves 151 corresponding to and matching the reinforcement plates 113 are opened through the inner wall of the reinforcement frame 15. Through the coordination of the reinforcement frame 15 and the reinforcement plate 113, the connection strength and supporting capacity of the connection between the two bridge bodies 1 are further improved.

[0034] Furthermore, the top end surface of the reinforcement frame 15 is symmetrically provided with a limiting column 153, and the connecting plate 13 at one end of the bridge body 1 close to the reinforcement frame 15 is provided with a limiting groove 136 for the displacement of the limiting column 153. By setting the limiting groove 136 and the limiting column 153, the reinforcement frame 15 can be limited in displacement. Positioning threaded holes 137 are provided at both ends of the limiting groove 136. A fastening bolt 16 is screwed in the positioning threaded hole 137. A limiting hole 161 for the limiting column 153 to be inserted is provided at the bottom of the fastening bolt 16. The setting of 16 and the positioning threaded hole 137 can position and fix the reinforcement frame 15. When the bridge body 1 is not spliced, the reinforcement frame 15 is stored at the bottom of the bridge body 1, and the limiting column 153 at the top of the reinforcement frame 15 is located in the limiting groove 136 at one end away from the docking plate 132, and is fixed by the fastening bolt 16. When the bridge body 1 is spliced, the front of the reinforcement frame 15 moves to the bottom of the adjacent bridge body 1, and the limiting column 153 at the top of the reinforcement frame 15 is located in the limiting groove 136 at one end close to the docking plate 132, and is fixed by the fastening bolt 16.

[0035] For better effect, driving handles 152 are provided on the left and right outer side walls of the reinforcement frame 15 to facilitate the staff to operate the reinforcement frame 15.

[0036] The working principle of this utility model:

[0037] During installation, align the guide plate 122 on the bridge body 1 with the guide groove 121 on the adjacent bridge body 1 and insert it downward from the top of the guide groove 121. At the same time, the assembly frame 112 on the bridge body 1 is inserted into the assembly groove 111 on the adjacent bridge body 1. During the insertion process, when the docking plate 132 on the bridge body 1 is close to the docking groove 131 on the adjacent bridge body 1, the driving rod 145 is pressed toward the middle of the fixing block 141, thereby driving the locking rod 144 to move inward. At the same time, the compression spring 143 is squeezed and elastically deformed until the front end of the locking rod 144 is completely received in the accommodating cavity 142. After the fixing block 141 is inserted into the fixing groove 134, release the driving rod 145. The compression spring 143 is reset under the elastic action, driving the front end of the locking rod 144 to extend outward and be inserted into the locking groove 135. Thereby, the two bridge frame bodies 1 are locked, and then the driving handle 152 is pushed to drive the reinforcement groove 151 at the front of the reinforcement frame 15 to be plugged into the reinforcement plate 113 on the adjacent bridge frame body 1. At the same time, the limiting column 153 at the top of the reinforcement frame 15 is synchronously moved to the other end of the limiting groove 136 with the reinforcement frame 15. Finally, the fastening bolt 16 is screwed into the positioning threaded hole 137 where the limiting column 153 is located. At the same time, the upper part of the limiting column 153 is inserted into the limiting hole 161 on the fastening bolt 16, thereby fixing the reinforcement frame 15 on the outside of the connection between the two adjacent bridge frame bodies 1. When the bridge frame body 1 needs to be disassembled, the above operation is reversed, and the driving rod 145 is pressed toward the middle of the fixing block 141 to retract the locking rod 144 into the accommodating cavity 142. The bridge frame body 1 is lifted upward to complete the disassembly of the bridge frame body 1.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0039] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
