[0002] The electronic screen can display changing numbers, text, graphics and images. It can be used not only in indoor environments but also in outdoor environments. It has advantages that projectors, TV walls and LCD screens cannot match. When the electronic screen is used outdoors, the wiring harness needs to be routed to the power source for connection across the road. If the wiring harness is placed directly on the road surface, it is easy to be damaged by passing vehicles. Therefore, a protective device is needed to protect the wiring harness crossing the road surface.

[0003] The prior art discloses a pipeline protection structure for road construction that can be quickly disassembled and assembled with publication number CN113300309A. The protection device can not only protect the pipeline and prevent it from being damaged by being crushed by passing vehicles, but also can be quickly spliced ​​and disassembled without the need for bolt connection, with simple operation and fast disassembly and assembly speed.

[0004] Although the protective device can be quickly disassembled and assembled, there are still some defects in the actual use process. Since the wire crossing plate lacks a drainage structure and most of the wire crossing plates are made of softer plastic material, when the device is placed on a sunken or inclined road section for use, too much water will accumulate inside the wire crossing plate, and the wiring harness will be soaked in water, which poses a great safety hazard and greatly reduces the protection effect of the electronic screen wiring harness.

[0005] Therefore, an outdoor electronic screen harness protection structure is proposed to solve the above problems. Summary of the invention

[0009] In the above technical solution, further, a slope is provided on the bottom end of the extrusion block away from the groove.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 6The wire harness protection structure of an outdoor electronic screen shown in the figure includes a wire-passing plate body 1, a groove 2 for placing the wire harness is opened at the top of the wire-passing plate body 1, a top plate 3 is hingedly connected to the top of the groove 2, a sunken drainage groove 4 is opened on one side of the groove 2, a water-absorbing sponge 5 is fixedly connected to the bottom of the drainage groove 4, and the water-absorbing sponge 5 is arranged near one side of the groove 2 and extends to the bottom of the groove 2, an extrusion block 6 for squeezing the water-absorbing sponge 5 is slidably connected to the inner side of the drainage groove 4, a lower L-shaped rod 7 is fixedly connected to the top of the extrusion block 6, and a slide groove 8 is opened on the inner side of the groove 2 and at a position corresponding to the lower L-shaped rod 7, the side wall of the lower L-shaped rod 7 passes through the slide groove 8 and is arranged in the groove 2, and an arc-shaped Elastic plate 9, several upper L-shaped rods 10 are fixedly connected to the bottom of the elastic plate 9 and penetrate the top plate 3 to be arranged in the groove 2. It should be noted here that both sides of the upper L-shaped rod 10 above the top plate 3 are hollowed out. When a vehicle passes by, it will first squeeze the side wall of the elastic plate 9, and will squeeze the upper L-shaped rod 10 obliquely, which can avoid hindering the upper L-shaped rod 10 from sliding obliquely, and at this time, the upper L-shaped rod 10 can still squeeze the lower L-shaped rod 7. The bottoms of several upper L-shaped rods 10 are in contact with the top of the lower L-shaped rod 7. Several drainage holes 11 are opened on the side wall of the drainage groove 4 and penetrate the side wall of the wire plate body 1. Several upper springs 12 are fixedly connected between the top of the drainage groove 4 and the top of the extrusion block 6;

[0027] When in use, when there is water accumulated in the groove 2, the water accumulated in the groove 2 will be absorbed on the water absorbent sponge 5 under the action of the water absorbent sponge 5. Then, when a vehicle passes over the line board body 1, the gravity of the vehicle will squeeze the elastic plate 9, causing the elastic plate 9 to elastically deform and move downward, which will drive the upper L-shaped rod 10 to move downward and squeeze the lower L-shaped rod 7, thereby driving the squeezing block 6 to slide downward and stretching the upper spring 12. Then the water absorbent sponge 5 is squeezed, so that the water absorbed on the water absorbent sponge 5 is squeezed out and then discharged through the drainage hole 11. This process can be repeated to completely drain the accumulated water in the groove 2. When the vehicle is reset after driving away, the elastic plate 9 resets itself under its own elasticity and repeats the above operation in reverse.

[0028] In order to prevent the water squeezed on the water-absorbing sponge 5 from flowing into the groove 2, a baffle 13 for blocking water is fixedly connected to the bottom of the drainage groove 4. An inward-facing groove 14 is provided at the bottom of the water-absorbing sponge 5 and at a position corresponding to the baffle 13. The baffle 13 can serve as a blocking end for the drainage groove 4 to prevent the squeezed water from flowing into the groove 2. An inclined surface is provided at the bottom end of the squeezing block 6 away from the groove 2, so that the squeezing block 6 first squeezes the water-absorbing sponge 5 away from the drainage hole 11, thereby facilitating the discharge of the squeezed water. The bottom of the drainage groove 4 is inclined toward the drainage hole 11, so that the squeezed water is guided to the drainage hole 11 side for rapid discharge.

[0029] In order to prevent the vehicle from slipping when passing through the line board body 1, the elastic plate 9 is made of elastic metal plate material, and a plurality of anti-skid grooves 15 are provided on the top of the elastic plate 9. The anti-skid grooves 15 can increase the anti-skid performance of the vehicle when passing by.

[0030] A plurality of upper water troughs 16 are equidistantly provided at the front end of the wire board body 1, and a plurality of lower water troughs 17 are equidistantly provided on the side wall of the wire board body 1. The upper water troughs 16 are provided to facilitate the outflow of water on the road and avoid being blocked by the wire board body 1. If too much water accumulates on the road, the lower water troughs 17 are provided to facilitate the discharge of water accumulated on both sides of the wire board body 1, thereby improving the practical performance of the device.

[0031] In order to improve the stability of the wire-passing plate body 1 when it is spliced, a pair of T-slots 18 are provided on both sides of the top of the wire-passing plate body 1, an inward-recessed docking groove 19 is provided at one end of the wire-passing plate body 1 and is connected to two of the T-slots 18, a docking plate 20 is fixedly connected to the other end of the wire-passing plate body 1 and the corresponding position of the docking groove 19, a limiting plate 21 is slidably connected to the inner side of the docking groove 19, a through groove 22 for bolts to pass through is provided at the top of the limiting plate 21 and the corresponding position of the T-slot 18, a sunken limiting groove 23 is provided at the top of the docking plate 20, a limiting block 24 is fixedly connected to the bottom of the limiting plate 21 and the corresponding position of the limiting groove 23, and a pair of lower springs 25 are fixedly connected between the inner bottom end of the T-slot 18 and the bottom of the limiting plate 21;

[0032] When installing the wire crossing plate body 1, first dock the wire crossing plate body 1 that needs to be docked, and insert the docking plate 20 into the corresponding docking groove 19, then hit the expansion bolt cap on the road, and then pass the bolt through the through groove 22 and the T-slot 18 and thread it in the expansion bolt cap. In the process of tightening the bolt, the limit plate 21 will be squeezed downward to slide downward, and the lower spring 25 will be compressed, thereby driving the limit block 24 to be inserted into the limit groove 23. Then, when the bolt is tightened, the limit block 24 will be tightly inserted into the limit groove 23, so as to achieve a tight docking between adjacent wire crossing plate bodies 1, avoid long-term thrust when vehicles pass by, so that the two wire crossing plate bodies 1 are gradually separated, and it is easy to pull the wiring harness to cause damage, thereby further improving the protection effect of the electronic screen wiring harness.
