One end of the second sliding rod 208 extends to the outside of the second sliding groove 207 and is fixedly connected to a second driving disk 209. The other end of the second sliding rod 208 is fixedly connected to a second insertion rod 210. The second insertion rod 210 is provided with a locking groove 211 for the first insertion rod 204 and the limit block 205 to be plugged in. The other end of the bridge body 1 is fixedly connected to an assembly part 3, and the front end of the assembly part 3 is fixedly connected to a U-shaped structure connecting plate 301. The connecting plate 301 is provided with a fixing hole 302 for the second insertion rod 210 to be plugged in when two adjacent bridge bodies 1 are connected end to end. The outer wall of the connecting plate 301 is provided with a plurality of reinforcing plates 303 with a trapezoidal structure.

[0026] Furthermore, the mounting portion 2 is provided with a connecting groove 212 for the connecting plate 301 to be plugged in and a reinforcing groove 213 that fits with the reinforcing plate 303. By setting the connecting groove 212 and the connecting plate 301, the bottom supporting force at the connection between the two bridge frame bodies 1 is improved. By setting the reinforcing groove 213 and the reinforcing plate 303, the connection strength between the two bridge frame bodies 1 is further strengthened.

[0027] Furthermore, a first insertion slot 214 capable of allowing the first insertion rod 204 to move up and down is defined at the bottom of the first sliding slot 201 , and a limiting slot 215 capable of allowing the limiting block 205 to move up and down is defined inside the first insertion slot 214 .

[0033] refer to Figure 6 After the installation of the two adjacent bridge bodies 1 is completed, the second insertion rod 210 rebounds under the elastic action of the second spring 218 and clamps the first insertion rod 204. The first insertion rod 204 rebounds under the elastic action of the first spring 216 and drives the limit block 205 to clamp the second insertion rod 210. The limit block 205 fixes the first insertion rod 204 and the second insertion rod 210 to prevent the first insertion rod 204 and the second insertion rod 205 from separating from each other, thereby enhancing the stability of the connection between the two bridge bodies 1.

[0034] The working principle of this utility model:

[0035] During installation, align the connecting plate 301 on the bridge body 1 with the connecting groove 212 on the adjacent bridge body 1 and plug them in, so that the two bridge bodies 1 are initially fixedly connected. At the same time, the reinforcing plate 303 on the outer wall of the connecting plate 301 is plugged into the reinforcing groove 213 outside the connecting groove 212, further strengthening the connection strength between the two bridge bodies 1. At this time, the fixing holes 302 on the connecting plate 301 are connected one by one with the second plugging groove 217 on the adjacent bridge body 1, and the second driving disk 209 is pressed inward to make the second plugging rod 210 pass through the fixing hole 302 and resist against the inner wall of the second plugging groove 217. At the same time, the second spring 218 is stretched and elastic Deformation, then press the first driving disk 203 downward to make the first insertion rod 204 and the limit block 205 pass through the locking groove 211, and at the same time the first spring 216 is stretched to undergo elastic deformation, and then release the second driving disk 209, and the second insertion rod 210 rebounds under the elastic action of the second spring 218 to clamp the first insertion rod 204, and finally release the first driving disk 203, and the first insertion rod 204 rebounds under the elastic action of the first spring 216 to drive the limit block 205 to clamp the second insertion rod 210, so that the first insertion rod 204 cannot be separated from the locking groove 211, thereby firmly locking the connecting plate 301 in the connecting groove 212, thereby making the bridge body 1 stably connected.
