Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Embodiment 1: As shown in Figure 1, this multifunctional insulating cross arm includes a cross arm body 1, and the cross arm body 1 is made of epoxy resin material. The cross-arm body 1 is provided with a fixer 2 for fixing it on the utility pole, and the cross-arm body 1 is provided with a cable clamp 3 for fixing horizontal or vertical cables. Wherein the fixer 2 is located in the middle of the cross-arm body 1, two cable clamps 3 for fixing the longitudinal cables are respectively provided on both sides of the cross-arm body 1, and a cable clamp 3 for fixing the horizontal cables is respectively provided at both ends of the cross-arm body 1.

As shown in FIG. 3 , the fixer 2 includes a main body 21 fixed on the cross-arm body 1 , the main body 21 is fixed to the cross-arm body 1 through a pair of hoops 22 , and the position of the fixer 2 can be adjusted according to actual usage conditions. One end of the main body 21 is provided with a front fixing body 23 for fixing the chain 25 , and the other end is provided with a rear fixing body 24 which can cooperate with the chain 25 . The main body 21 is provided with a pair of triangular support bodies 26 . The rear fixed body 24 is provided with a slot whose width is greater than the thickness of the 25 rings of the chain and less than the width of the 25 rings of the chain. The front fixed body 23 is provided with a lock chain holding device.

When in use, wind the chain 25 tightly around the wire column at the target location, and the end of the chain 25 is snapped into the draw-in groove of the rear fixed body 24, and the chain holding device on the front fixed body 23 is adjusted, that is, the front end of the screw rod of the front fixed body 23 is tightened push the positioning block on the screw rod forward, and fix the four points of the positioning block, the rear fixing body 24, and the two triangular support bodies 26 with the wire post, and add the friction force formed by the chain 25 and the wire post, and the horizontal The carrier 1 is positioned on the wire column.
