Each group of cable bodies 1110 is embedded in the interior of the positioning hole 240. In the laying of network engineering cables, the cables are embedded into the interior of the first bridge 140, wherein the first bridge 140 is used to wrap the cables to increase the protection of the cables. The fixing seat 110 is fixed to the floor slab at the top of the floor by a fixing piece, and is connected to the first bridge 140 through the connecting plate 130, and the first bridge 140 is hung.

The position of the supporting block 230 is adjusted by the fixing rod 220. The lifting block 230 is positioned in a row, making it more stable during the lifting process. A lifting groove 250 is provided inside the lifting block 230, and a sliding block 260 is embedded in the lifting groove 250. The fixing rod 220 passes through the interior of the sliding block 260. The upper end of the supporting block 230 is connected to a support plate 270, and a positioning hole 240 is provided on the upper end of the support plate 270. A rack 280 is fixedly welded to the top of the supporting block 230. In the process of fixing the cable body 1110, the cable body 1110 is fixed through the positioning hole 240, and the same type of cable bodies 1110 are embedded in the same group of positioning holes 240. They are separated by the positioning holes 240 to avoid confusion between the cable bodies 1110, which is more convenient in later maintenance.

[0039] The inner wall of the first bridge 140 is connected to a lifting assembly 3, which includes a driving rod 310. The inner wall of the first bridge 140 is connected to the driving rod 310. The upper end of the driving rod 310 is fixedly connected to a connecting shaft 320. The upper end of the connecting shaft 320 is connected to a deflection rod 340. The top of the deflection rod 340 is connected to a transmission gear 350. The central axis of the transmission gear 350 is fixedly connected to a shaft. The side of the shaft away from the transmission gear 350 is rotatably connected to the deflection rod 340. The transmission gear 350 and the rack 280 are horizontally aligned. The driving rod 310 is fixedly connected to the inner wall of the first bridge 140. 0 is connected to the outer surface of the transmission belt 360, and the side of the transmission belt 360 away from the driving rod 310 is connected to the upper end of the deflection rod 340. The inner wall of the transmission belt 360 is provided with uneven teeth, and the teeth are engaged with the shaft rod embedded in the deflection rod 340. The driving rod 310 is installed on the side close to the rack 280. The upper end of the driving rod 310 is provided with teeth, and the teeth are embedded in the interior of the transmission belt 360. The transmission belt 360 is wrapped around the upper end of the teeth, and the rotation of the driving rod 310 drives the transmission belt 360 The rotation of the transmission belt 360 is driven by the drive rod 310 to rotate, and the rotation of the transmission belt 360 drives the rotation of the transmission gear 350. When the transmission gear 350 and the rack 280 remain in meshing state, the rack 280 is driven to rise by the rotation of the transmission gear 350. When the rack 280 rises, it also drives the lifting block 230 to rise. When the lifting block 230 rises, it drives the support plate 270 and the positioning hole 240 to rise, wherein the cable body 1110 embedded in the positioning hole 240 is lifted up. As the lifting block 230 continues to rise, the cable body 1110 is lifted up. It is separated from the wrapping of the first bridge 140, which makes it more convenient in later maintenance and will not be blocked by the first bridge 140 during operation. When the cable body 1110 is lifted, in order to prevent the cable body 1110 from shifting to one side, when the support block 230 rises, the sliding block 260 slides inside the lifting groove 250, and the cable body 1110 inside the positioning hole 240 will be pressed by the fixing rod 220, and the cable body 1110 will be bent by the force, and the cable body 1110 will be embedded between the fixing rod 220 and the support plate 270, thereby restricting the cable body 1110.

[0040] The interior of the driving rod 310 is embedded in an embedded rod 330, and the top of the embedded rod 330 is connected to a locking rod 380, which is embedded in the reserved groove 390. The locking rod 380 extends to the outside of the driving rod 310 through the reserved groove 390, and the upper end of the embedded rod 330 is provided with a slot 370, and the upper end of the connecting shaft 320 is provided with a reserved slot 390. The bottom end of the supporting block 230 is fixedly connected to a fixing pin 3110, and the upper end of the fixing pin 3110 is connected to a limiting piece 3120. The fixing pin 3110 corresponds to the transmission gear 350, and the limiting piece 3120 is arranged in an arc shape. The limiting pieces 3120 are distributed on the front and back of the fixing pin 3110. One end of the limiting piece 3120 is fixedly connected to the upper end of the fixing pin 3110, and the other end is suspended on the fixing pin 3110. The upper end of the deflection rod 340 is deflected by controlling the rotation of the embedded rod 330. The embedded rod 330 is rotated to engage the transmission gear 350 at the front end of the deflection rod 340 with the rack 280. Only under the transmission can the lifting block 230 be lifted. Before the lifting block 230 is lifted, it is also necessary to complete the overlap between the rack 280 and the transmission gear 350. The deflection of the positioning hole 240 is specifically operated as follows:

[0041] When the staff needs to check one group of cables, they can rotate the corresponding embedded rod 330. The cable body 1110 will be divided into ten columns vertically when it is embedded in the positioning hole 240. For example, the cable body 1110 that needs to be repaired is located in the third and fourth columns. By pushing the embedded rod 330, the locking rod 380 at the top of the embedded rod 330 is embedded in the connecting shaft 320 at the bottom of the third and fourth columns. After pushing the locking rod 380 to embed into the reserved groove 390, the connecting shaft 320 is driven to rotate by rotating the embedded rod 330. When the connecting shaft 320 rotates, the deflection rod 340 is driven to deflect. After deflection, the deflection rod 340 and the bottom surface of the first bridge 140 remain perpendicular, which also keeps the transmission gear 350 and the rack 280 engaged. After meshing, the embedded rod 330 is pulled out by rotation, so that the locking rod 380 and the reserved groove 390 are disconnected. In order to make the rack 280 The meshing between the transmission gear 350 is more compact. When the positioning hole 240 is close to the supporting block 230, the fixing pin 3110 and the limiting plate 3120 are embedded in the inside of the positioning hole 240, thereby limiting the position of the positioning hole 240 and increasing the connection between the rack 280 and the transmission gear 350. At this time, the transmission belt 360 is driven by rotating the driving rod 310, and then the transmission gear 350 is driven to rotate, so that the supporting block 230 can be raised. By inspecting the different positions of the cables, the locking rod 380 is embedded in the reserved grooves 390 at different positions by pushing the embedded rod 330 to complete the deflection of the positioning hole 240.
