With the continuous development of technology, people's demand for electricity is very urgent. As the existing long-distance electricity transmission uses large-scale power towers, and short-distance electricity is supported by pole towers, among which the tension plate is an indispensable connection fitting.

[0003] Chinese patent document CN210297191 U discloses an adjustable tension-resistant joint plate with a compact and flexible structure, easy use and installation, and superior performance. Different split spacings and split numbers can be obtained by installing the hanging plate bolts in the installation adjustment holes at different positions, thereby reducing the construction workload and saving costs.

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As Figures 1 - 6 shown, an adjustable tension link plate includes a circular ring plate 1. The outer surface of the circular ring plate 1 is fixedly installed with a protrusion 2 and two arc plates 14, and the two arc plates 14 are located on the front and rear sides below the protrusion 2. The outer surface of the protrusion 2 is slidably connected with two tension link plates 2 4. A tension link plate 1 3 is arranged below the tension link plate 2 4. The front side of the upper surface of the tension link plate 2 4 is fixedly installed with a connecting plate 5 by screws, and the rear side of the connecting plate 5 is L-shaped. Three counterbores 13 are penetrated and opened on the left side of the upper surface of the connecting plate 5. Straight slots 6 are opened on the left side of the upper surface of the tension link plate 2 4 and the rear side of the upper surface of the tension link plate 1 3. An adjustable cylinder 7 is slidably connected to the inner surface of the straight slot 6. A rubber pad 15 is fixedly installed on the lower surface of the circular ring plate 1. A jack 12 is opened on the rear side of the upper surface of the tension link plate 2 4. An internal thread cylinder 17 is movably sleeved on the inner wall of the jack 12. A sliding slot 8 is opened on the front side of the upper surface of the tension link plate 1 3.

[0026] Insert the socket 12 on the tension-resistant joint plate 24 into the internal threaded tube 17, rotate the stud 9 to make it threadedly connected to the internal threaded tube 17, put the tension-resistant joint plate 13 on the arc plate 14, put the tension-resistant joint plate 24 on the protrusion 2, put the connecting plate 5 on the protrusion 2, put one side of the connecting plate 5 on the tension-resistant joint plate 24, and install the tension-resistant joint plate 13 and the connecting plate 5 on the arc plate 14 and the tension-resistant joint plate 24 respectively by screws. When it is necessary to reduce the number of splits, push the stud 9 to drive the internal threaded tube 17 to slide along the slide groove 8, drive the tension-resistant joint plate 24 to move, and make the tension-resistant joint plate 13 It is overlapped and aligned with the straight groove 6 on the tension-resistant connecting plate 2 4, and finally the number of connecting plate splits is changed. The adjustment process reduces the spatial structure of the connecting plate, makes the line clear, and is convenient for maintenance personnel to repair. The tension-resistant connecting plate 2 4 and the connecting plate 5 and the tension-resistant connecting plate 1 3 and the arc plate 14 are installed by screws, so that the disassembly and assembly of the tension-resistant connecting plate 1 3, the tension-resistant connecting plate 2 4, and the connecting plate 5 are more flexible, and the connecting plate is divided into multiple detachable parts. When a component is broken, only the component needs to be replaced, and the remaining components can be recycled to save resources. When in use, a rubber pad 15 is provided to have an anti-slip effect.

[0027] like Figures 1 - 6 As shown, the cross-sections of the straight slot 6 and the adjustable cylinder 7 are both I-shaped, and the inner surface of the slide groove 8 is slidably connected with a cylindrical slider 16. The slide groove 8 is arc-shaped and has a T-shaped cross-section. The upper surface of the slider 16 is welded to the lower surface of the internal threaded cylinder 17, and the inner surface of the internal threaded cylinder 17 is threadedly connected with a stud 9.

[0028] The threaded action of the stud 9 and the internal threaded tube 17 makes the disassembly and assembly of the internal threaded tube 17 and the stud 9 more convenient. Since the internal threaded tube 17 is inserted into the socket 12 on the tension-resistant connecting plate 2 4, pushing the stud 9 can drive the slider 16 and the internal threaded tube 17 to slide along the slide groove 8, thereby driving the tension-resistant connecting plate 2 4 to move, so that the straight slots 6 on the tension-resistant connecting plate 1 3 and the tension-resistant connecting plate 2 4 overlap and align, and finally realize the change of the number of splitting of the connecting plate.

[0031] like Figures 1 - 4 As shown, the upper surface of the arc plate 14 is fixed to the front side of the lower surface of the tension link plate 13 by screws.

[0032] The tension insulator link plate 1-3 and the arc-shaped plate 14 are installed by screws, making the disassembly and assembly of the tension insulator link plate 1-3 more flexible. When a certain component breaks, only that component needs to be replaced, and the remaining components can be recycled, saving resources.

Rotate the locking screw 11 to fix the tension insulator link plate 1-3 and the tension insulator link plate 2-4. Place the tension insulator link plate 1-3 on the arc-shaped plate 14, make the tension insulator link plate 2-4 sleeved on the protrusion 2, place the connecting plate 5 on the protrusion 2, and make one side of the connecting plate 5 placed on the tension insulator link plate 2-4. Then install the tension insulator link plate 1-3 and the connecting plate 5 on the arc-shaped plate 14 and the tension insulator link plate 2-4 respectively by screws. When it is necessary to reduce the number of splits, rotate the locking screw 11 to disengage it from the tension insulator link plate 1-3, push the stud 9 to drive the slider 16 and the internal thread cylinder 17 to slide along the chute 8, drive the tension insulator link plate 2-4 to move, make the straight slot openings 6 on the tension insulator link plate 1-3 and the tension insulator link plate 2-4 coincide and align, make the threaded hole on the tension insulator link plate 2-4 coincide with the threaded hole 10 on the tension insulator link plate 1-3, and then rotate the locking screw 11 to fix the tension insulator link plate 1-3 and the tension insulator link plate 2-4, ensuring the stable connection of the link plate. Finally, the change of the split number of the link plate is realized. The adjustment process reduces the spatial structure of the link plate, making the line clear and convenient for maintenance personnel to repair. Through the threaded action of the stud 9 and the internal thread cylinder 17, the disassembly and assembly of the internal thread cylinder 17 and the stud 9 are more convenient. The tension insulator link plate 2-4 and the connecting plate 5, as well as the tension insulator link plate 1-3 and the arc-shaped plate 14, are installed by screws, making the disassembly and assembly of the tension insulator link plate 1-3, the tension insulator link plate 2-4, and the connecting plate 5 more flexible. The link plate is divided into multiple detachable parts. When a certain component breaks, only that component needs to be replaced, and the remaining components can be recycled, saving resources. A rubber pad 15 is provided during use to achieve an anti-slip effect.
