DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] like Figure 1 As shown, a guiding and anti-falling structure of an insulating cross arm includes a utility pole 10, on the top wall of which a guide rod 11 is fixedly mounted, and on the left and right side walls of the guide rod 11 are provided a guide device for guiding the wires and preventing them from falling off, and the guide device includes two movable slots 12.

[0028] It is worth noting that the utility pole 10 and the guide rod 11 have been disclosed in a live working insulating cross arm (201610269108.X), and will not be described in detail here.

[0029] In specific use, the prior art usually guides the wires by moving the card slot 12. The guiding device can guide the wires and can also effectively prevent the wires from being disengaged or shaking significantly.

[0030] In summary, by providing the guide device, the guide device can guide the electric wires and can also effectively prevent the electric wires from being detached or shaking greatly. The guide device is easy to use and has a simple structure.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the two movable card slots 12 are respectively fixedly mounted on the left and right side walls of the guide rod 11, and the front and rear side walls of the two movable card slots 12 located above the guide rod 11 are both hollowed out, and the two hollows are interconnected. A through hole 15 is fixedly mounted on the top wall of the cavity and the left and right side walls of the movable card slot 12.

[0032] A left and right movable plate 14 is disposed on the left and right side walls of the movable slot 12 , and a first connecting rod 16 is fixedly installed on the side wall where the two left and right movable plates 14 are close to each other. The two first connecting rods 16 pass through the corresponding through holes 15 .

[0033] A clamping plate 17 is fixedly installed on the side wall where the two first connecting rods 16 are close to each other, and the two clamping plates 17 are both located in the cavity of the movable slot 12. Two springs 18 are fixedly installed on the side wall where the two left and right movable plates 14 are close to each other, and the ends of the two groups of springs 18 close to each other are fixedly connected to the left and right side walls of the movable slot 12 respectively.

[0034] During specific use, the two sets of springs 18 both exert a force to move the two left and right movable plates 14 toward positions close to each other. When the two left and right movable plates 14 move toward positions close to each other, the two first connecting rods 16 can be driven to move toward positions close to each other. When the two first connecting rods 16 move toward positions close to each other, the two clamping plates 17 can be driven to move toward positions close to each other. When the two clamping plates 17 move toward positions close to each other, the wires can be clamped and limited, thereby limiting the left and right ends of the wires. The perforations 15 can limit the clamping plates 17 and the left and right movable plates 14 through the first connecting rods 16, and the guide rods 11 can limit the movable slots 12.

[0035] In summary, by setting the guide rod 11, the movable slot 12, the upper movable plate 13, the left and right movable plates 14, the through hole 15, the first connecting rod 16, the clamping plate 17 and the spring 18, the two clamping plates 17 can clamp the left and right side walls of the wire through the force of the spring 18, so as to limit the wire and effectively prevent the wire from detaching and shaking drastically.

[0036] like Figure 5 and Figure 6 As shown, an upper movable plate 13 is provided on the top wall of the movable slot 12, a second connecting plate 25 is fixedly installed on the bottom wall of the upper movable plate 13, the second connecting plate 25 passes through the through hole 15 above, and two springs 18 are also fixedly installed on the bottom wall of the upper movable plate 13 and the top wall of the movable slot 12.

[0037] Two fixing blocks 22 are fixedly installed on the front and rear ends of the bottom wall of the second connecting plate 25, and a fixing plate 24 is provided at one end of the front and rear fixing blocks 22 close to each other. The front and rear side walls of the fixing plate 24 are hollow, and a torsion spring 23 is fixedly installed at one end of the front and rear fixing blocks 22 close to each other. The ends of the two torsion springs 23 close to each other are fixedly connected to the cavity of the fixing plate 24.

[0038] A bottom plate 19 is fixedly mounted on one end of the two fixed plates 24 away from each other. A telescopic groove 20 is opened on the wall surface of the two bottom plates 19 away from each other. A telescopic plate 21 is movably mounted in the cavity of the two telescopic grooves 20.

[0039] When in use, the two springs 18 on the bottom wall of the upper movable plate 13 have the force to pull the upper movable plate 13 downward. When the upper movable plate 13 moves downward, the second connecting plate 25 can be driven to move downward. When the bottom plate 19 moves downward, the two sets of fixed blocks 22 can be driven to move downward. The movement of the two sets of fixed blocks 22 can drive the fixed plate 24 to move through the fixed plate 24. The torsion spring 23 can make the fixed plate 24 automatically reset after rotation. When the two fixed plates 24 move downward, the two bottom plates 19 can be driven to move downward. The downward movement of the two bottom plates 19 can drive the telescopic plate 21 to move downward through the telescopic groove 20. The left and right side walls of the two telescopic plates 21 are respectively fitted with the side walls of the two clamping plates 17 that are close to each other. When the bottom plate 19 and the telescopic plate 21 move downward, the upper and lower side walls of the wires can be clamped and limited by the bottom wall of the cavity of the mobile card slot 12 and the bottom wall of the bottom plate 19 and the telescopic plate 21, which can further prevent the wires from detaching or shaking significantly.

[0040] In summary, by setting the upper movable plate 13, spring 18, bottom plate 19, telescopic slot 20, telescopic plate 21, fixed block 22, torsion spring 23, fixed plate 24 and second connecting plate 25, the bottom plate 19 and telescopic plate 21 can cooperate with the bottom wall of the cavity of the movable card slot 12 to limit the upper and lower side walls of the wire, which can further prevent the wire from detaching or shaking drastically. It is easy to use and has a simple structure.
