Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Existing safety protection fences are usually composed of multiple unit fences spliced together. Although they are convenient for assembly and transportation, each unit fence is usually a standardized module, which means that the length of the protection fence formed by their combination can only be n times the length of the unit fence, and the length of the protection fence cannot be flexibly adjusted, resulting in the protection fence being difficult to adapt to construction sites of different sizes, and there is likely to be a problem of being too large or too small in size.

[0026] To solve the defects existing in the above protection fence during use, please refer to Figures 1 - 8, a kind of electric power construction safety protection fence provided by the utility model can flexibly adjust the overall width of the protection fence, can install the protection fence on door frames of different sizes, and expand the applicable range of the protection fence. The protection fence takes a protection plate 1 as the basic structure. Both sides inside the protection plate 1 are slidably installed with adjusting bars 2. The back of the protection plate 1 is provided with an adjusting mechanism 3 for controlling the two adjusting bars 2 to expand and contract towards both sides. By controlling the sliding distance of the two adjusting bars 2, the overall width of the device can be adjusted. One end of the adjusting bar 2 is installed with a fixing frame 7. Threaded holes for installing fastening bolts are opened at the four corners of the fixing frame 7. A limiting mechanism 4 for fixing the adjusting bar 2 inside the protection plate 1 is arranged inside the adjusting bar 2. After adjusting the overall width of the device, insert the adjusting bar 2 into the fixing frame 7, and then connect two adjacent fixing frames 7 through expansion bolts, which can realize the splicing of multiple protection plates 1. And during the insertion process of the adjusting bar 2, the limiting mechanism 4 can be triggered to lock the adjusting bar 2 to prevent the adjusting bar 2 from sliding automatically, thus ensuring the stability of the device.

[0027] Since after inserting the two adjusting bars 2 into the two fixing frames 7, if the adjusting bars 2 are not fixed, the two adjusting bars 2 may automatically contract, resulting in loosening between the adjusting bars 2 and the fixing frames 7, affecting the overall stability of the device. To solve this technical problem, a pressing plate 41 slidably installed inside the adjusting bar 2 is provided. The pressing plate 41 is slidably installed inside the adjusting bar 2. One side of the pressing plate 41 is fixedly connected with a telescopic spring 43. The telescopic spring 43 is arranged at one end of the pressing plate 41 close to the fixing frame 7. There are multiple telescopic springs 43, and the multiple telescopic springs 43 are longitudinally equidistantly distributed, and the number of the telescopic springs 43 is not less than two. The end of the telescopic spring 43 is fixedly connected to the inner side wall of the adjusting bar 2. The other side of the pressing plate 41 is fixedly connected with multiple limiting blocks 42. A rectangular groove 44 is opened on the back of the adjusting bar 2. A top block 45 is rotatably installed inside the rectangular groove 44. The multiple limiting blocks 42 are evenly distributed at equal intervals. Multiple through holes 46 for the limiting blocks 42 to slide out are opened on the adjusting bar 2. Limiting grooves 47 corresponding to the limiting blocks 42 are opened on the protection plate 1. When the adjusting bar 2 is inserted into the fixing frame 7, the fixing frame 7 squeezes the top block 45 to rotate clockwise. The top block 45 rotates clockwise and squeezes the pressing plate 41 to slide. The pressing plate 41 pushes the limiting blocks 42 to pass through the through holes 46. The limiting blocks 42 located inside the protection plate 1 can extend into the limiting grooves 47 through the through holes 46. The limiting grooves 47 limit the limiting blocks 42, which can limit the adjusting bar 2 from sliding along the protection plate 1, thereby realizing the self-locking of the adjusting bar 2, enhancing the stability of the protection plate 1 and the adjusting bar 2, avoiding the shaking of the adjusting bar 2, and ensuring the overall stability of the device.

[0028] To facilitate the control of the sliding of the two adjusting bars 2, refer to Figure 2As shown in the figure, the telescopic rod 31 is fixedly installed at the center of the back of the protection plate 1. The telescopic end of the telescopic rod 31 is fixedly connected with a connecting seat 32. The connecting seat 32 is slidably installed on the back of the protection plate 1, and connecting rods 33 are rotatably installed on both sides of the connecting seat 32. The ends of the two connecting rods 33 are respectively hinged to the two adjusting bars 2. By controlling the telescopic rod 31, the connecting seat 32 can be made to slide. The sliding of the connecting seat 32 can drive the connecting rods 33 to rotate. The rotation of the connecting rods 33 can pull or push the adjusting bars 2 to slide, so that the two adjusting bars 2 can approach or move away from each other, and thus the overall width of the device can be controlled.

[0029] To increase the smoothness of the sliding of the adjusting bar 2, a plurality of pulleys 6 for assisting the sliding of the adjusting bar 2 are fixedly installed on the top of the adjusting bar 2. The plurality of pulleys 6 are evenly distributed at equal intervals, which can more conveniently control the two adjusting bars 2.

[0030] Refer to Figure 1 As shown in the figure, a handle 5 is fixedly installed at the center of the top of the protection plate 1. An anti-slip sheath is installed outside the handle 5. By means of the handle 5, it is convenient to lift the protection plate 1, which not only facilitates the handling of the device, but also facilitates the removal of the protection plate 1 and the adjusting bar 2 from the fixing frame 7.

[0031] The specific implementation process of this embodiment is as follows: During installation, according to the size of the construction site, control the telescopic rod 31 to drive the connecting seat 32 to slide. The sliding of the connecting seat 32 can drive the connecting rods 33 to rotate. The rotation of the connecting rods 33 can pull or push the adjusting bars 2 to slide, so that the two adjusting bars 2 approach or move away from each other, and thus the overall width of the device can be adjusted. Subsequently, insert the two fixing frames 7 at the ends of the adjusting bars 2. The fixing frame 7 squeezes the top block 45 to rotate clockwise. The clockwise rotation of the top block 45 squeezes the pressure plate 41 to slide. The pressure plate 41 pushes the limiting block 42 through the through hole 46. The limiting block 42 located inside the protection plate 1 passes through the through hole 46 and extends into the limiting groove 47. The limiting groove 47 limits the limiting block 42, which can restrict the sliding of the adjusting bar 2 along the protection plate 1, so as to realize the self-locking of the adjusting bar 2. Finally, connect the adjacent two fixing frames 7 with fastening screws. With such a setting, the device can be assembled into guardrails of different lengths to meet the protection requirements for different construction sites and ensure the stability of the guardrail.
