[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a fixing bracket for overhead cables. Figure 1-Figure 2 , including a support frame 1, a positioning plate 2 is welded at the bottom end of the support frame 1, and can be directly fixed to the ground through the positioning plate 2, a movable column 8 is movably provided inside the top of the support frame 1, the movable column 8 can be movably extended and retracted in the support frame 1, and a support plate 6 is fixed to the top of the movable column 8, a support shaft 9 is fixed at the center of the top of the support plate 6, an overhead bracket 7 is fixedly connected to the end of the support shaft 9 away from the support plate 6, a limiting frame 14 is provided on the top of the overhead bracket 7, the overhead bracket 7 and the limiting frame 14 are symmetrically arranged, and a group of positioning grooves 10 are equidistantly provided at the ends of the overhead bracket 7 and the limiting frame 14 that are close to each other, which can be used for overhead placement of cables, and the positioning grooves 10 are set to an arc shape to fit the outer wall of the cable, and connecting frames 11 are symmetrically fixed on both sides of the overhead bracket 7.

[0020] A threaded drum 12 is rotatably provided on the connecting frame 11, and the internal thread on the top of the threaded drum 12 is connected to a reverse threaded rod 13. Since the end of the reverse threaded rod 13 away from the threaded drum 12 is movably connected to the outer wall of the limit frame 14, rotating the threaded drum 12 can drive the reverse threaded rod 13 to contract on its inner wall and drive the limit frame 14 to move downward, thereby adjusting the clamping distance between the limit frame 14 and the overhead bracket 7.

[0021] like Figure 3 As shown, movable support shafts 3 for support are symmetrically rotated on both sides of the bottom of the support plate 6, and a connecting ear 4 is welded to the bottom end of the movable support shaft 3. When the support plate 6 is adjusted to a suitable height, the supporting height of the movable support shaft 3 can be stretched. The movable support shaft 3 is a telescopic rod, and a movable groove 21 is opened inside the bottom end of the movable support shaft 3. A support member 22 is rotatably connected in the movable groove 21, and a fastener 23 is rotatably connected at one end of the support member 22 away from the movable groove 21, and a mounting plate 24 is welded to the bottom of the fastener 23. After adjusting to a suitable height, the connecting ear 4 and the mounting plate 24 can be connected and fixed to the ground, which further improves the fixing effect.

[0022] In addition, a cable reel 5 for storing cables is provided on the outer walls at both ends of the support plate 6. A plurality of wire grooves 16 are equidistantly provided on the edge of the cable reel 5 along the circumferential direction. The cable can be led out through the wire grooves 16 for use, which has a good positioning effect. A connecting block 15 for support is connected between the cable reel 5 and the support plate 6, and inner slideways 17 are symmetrically provided on the inner wall of the cable reel 5. Slide blocks 18 are slidably provided in the two inner slideways 17. A spring 20 is provided between the slide block 18 and the inner wall of the inner slideway 17. One end of the slide block 18 extends outside the inner slideway 17 and is fixed with a limit stopper 19. The limit stopper 19 can limit the outer wall of the cable to prevent it from falling off.

[0023] The implementation principle of a fixed bracket for overhead cables in the embodiment of the present application is as follows: the support frame 1 is installed by fixing the positioning plate 2 in advance with bolts. When laying cables, the movable column 8 can be lifted upward in advance according to the laying height of the cables, and then the movable support shafts 3 on both sides are extended downward to make their bottom ends close to the ground. Then, the support angle between the support member 22, the movable support shaft 3 and the fastener 23 is adjusted by rotation to make the mounting plate 24 parallel to the ground. Subsequently, the connecting ear 4, the mounting plate 24 and the ground are fixed by bolts, thereby completing the positioning of the movable support shaft 3 and achieving support for the bottom of the support frame 1 and the support plate 6. Then, the cable is passed between the overhead bracket 7 and the limit bracket 14. According to the thickness of the cable diameter, the connecting ear 4 is rotated to fix the mounting plate 24 and the ground. The threaded drum 12 on the frame 11 then drives the reverse threaded rod 13 to produce corresponding movement inside the threaded drum 12, so as to pull the limit frame 14 to fit the upper part of the cable for limiting, so that the cable can be tightly positioned in the positioning groove 10. During the cable connection process, the excess cable can be wound inside the winding drum 5, and the two sliders 18 inside the winding drum 5 are pinched to make the spring 20 inside the inner slide 17 contract, and then the excess cable can be wound around the two sliders 18 in circles, and then the slider 18 is reset. At this time, the limit block 19 can rebound to limit the front end of the cable to avoid falling off, and one end of the cable can be led out through the wire groove 16 for use. By providing multiple wire grooves 16, the wiring can be flexibly arranged according to the connection angle.
