[0002] Suspension clamps are essential hardware used to secure conductors in overhead power lines. A suspension clamp consists of a hull and a pressure plate; the conductor passes through the hull and is secured by the pressure plate.

[0007] Furthermore, the extension plates are arranged symmetrically on both sides of the hull.

[0008] Furthermore, the adjusting mechanism includes a lower cylinder, an upper cylinder, and a threaded rod. The lower cylinder is fixed to the pressure plate, the upper cylinder abuts against the connecting piece, and the threaded rod is screwed between the lower cylinder and the upper cylinder.

[0009] Furthermore, the top of the upper cylinder is provided with an arc-shaped groove for engaging with the connector.

[0010] Furthermore, the threaded rod is arranged perpendicular to the connector.

[0011] Furthermore, the threaded rod is arranged perpendicular to the conductor.

[0012] Furthermore, a connecting plate is attached to the connector.

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0017] Please see Figures 1 to 2 In this embodiment of the application, an overhead line fixing device is provided, which includes a hull 10 and a pressure plate 20. A connector 11 is provided on the hull 10, and a telescopic adjustment mechanism 30 is provided on the pressure plate 20. The top of the adjustment mechanism 30 abuts against the connector 11. When the adjustment mechanism 30 is extended, it pushes the pressure plate 20 toward the hull 10.

[0018] The hull 10 refers to a structure that defines a U-shaped threading space. The conductor 40 passes through the threading space of the hull 10, and the hull 10 is used to support the conductor 40.

[0019] The two side walls of the hull 10 are provided with outwardly protruding extension plates 14. The extension plates 14 are located on the same plane as the side walls of the hull 10, and the two extension plates 14 are symmetrically arranged on both sides of the wiring space of the hull 10.

[0020] The connector 11 refers to a detachable structure that passes between the two extension plates 14. The connector 11 includes, but is not limited to, bolts.

[0021] As an example, connector 11 is arranged perpendicularly to extension plate 14.

[0022] The pressure plate 20 refers to a structure that can apply pressure to the wire 40 passing through the hull 10. The pressure plate 20 is constructed as an arc-shaped plate that matches the shape of the wire 40. The pressure plate 20 is snapped into the wire-passing space of the hull 10 along the extension direction of the wire 40. The pressure plate 20 is pressed on top of the wire 40 to restrict the wire 40 within the wire-passing space of the hull 10.

[0023] The adjusting mechanism 30 refers to the structure that can press the pressure plate 20 onto the wire 40. The adjusting mechanism 30 includes a lower cylinder 31, an upper cylinder 32, and a threaded rod 33. The lower cylinder 31 is fixed to the pressure plate 20, the upper cylinder 32 abuts against the connector 11, and the threaded rod 33 is screwed between the lower cylinder 31 and the upper cylinder 32.

[0024] The lower cylinder 31, the upper cylinder 32, and the threaded rod 33 are arranged coaxially. The two ends of the threaded rod 33 are screwed into the corresponding lower cylinder 31 and upper cylinder 32. Rotating the threaded rod 33 can drive the lower cylinder 31 and upper cylinder 32 to move synchronously in opposite directions, thereby changing the overall length of the adjustment mechanism 30.

[0025] It should be noted that the lower cylinder 31 is fixedly connected to the pressure plate 20, and the upper cylinder 32 is snapped into the connector 11 to restrict the rotation of the upper cylinder 32, so as to ensure that when the threaded rod 33 is rotated, the lower cylinder 31 and the upper cylinder 32 can move synchronously.

[0026] As an example, the top of the upper cylinder 32 is provided with an arc-shaped groove that engages with the connector 11. The axis of the arc-shaped groove is arranged coaxially with the axis of the connector 11. The arc-shaped groove covers part of the circumferential surface of the connector 11, thereby restricting the rotation of the upper cylinder 32.

[0027] It should be noted that the threaded rod 33 is arranged perpendicularly to the connector 11. At the same time, the threaded rod 33 is also arranged perpendicularly to the wire 40. When the threaded rod 33 is rotated to make the lower cylinder 31 and the upper cylinder 32 move in opposite directions, the adjusting mechanism 30 can be tightened between the connector 11 and the pressure plate 20 to ensure that the pressure plate 20 can stably restrict the wire 40 inside the hull 10.

[0028] It should be understood that by rotating the threaded rod 33, the pressure plate 20 can be moved toward the wire 40, thus adjusting the amount of pressure applied by the pressure plate 20 to the wire 40.

[0029] In this embodiment, a connecting plate 12 is also attached to the connecting member 11. The connecting plate 12 is constructed in a U-shape. The connecting member 11 passes through the U-shaped groove of the connecting plate 12. An avoidance groove 121 for placing the upper cylinder 32 is provided on the connecting plate. A locking bolt 13 is provided on the connecting plate 12. The locking bolt 13 is used to fix the connecting plate 12 to the external components, thereby completing the fixed installation of the overhead line fixing device.

[0030] The overhead line fixing device provided in this application embodiment can adjust the pressure applied by the pressure plate 20 to the conductor 40 passing through the hull 10 by the adjustment mechanism 30 between the pressure plate 20 and the connector 11 to move the pressure plate 20 toward the hull 10.

[0031] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
