Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection insulators, in particular to a lightning protection insulator for preventing installation loosening. Background Art

[0002] A lightning protection insulator is a special insulator designed for overhead lines to provide lightning protection. Its main function is to connect the overhead insulated wire or bare wire to the fittings of the tension pole or corner pole, thereby tightening and insulating the overhead wire and playing a role in lightning protection. After the staff installs the lightning protection insulator and the insulated wire, due to the great influence of natural weather, the insulated wire and the lightning protection insulator vibrate due to bad weather such as strong wind and heavy rain, and the vibration causes the installation connection to loosen, which will lead to the failure of the power line and cause huge losses. Based on this, a lightning protection insulator for preventing installation loosening is proposed. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problem that the lightning protection insulator is easy to loosen during installation in the prior art, and a lightning protection insulator for preventing installation loosening is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A lightning protection insulator for preventing installation loosening includes a lightning protection insulator body. One end of the lightning protection insulator body is fixedly connected with an insulating sleeve. One end of the insulating sleeve is fixedly connected with a metal guide piece. A fixing pressing piece is arranged on the surface of the metal guide piece. One end of the fixing pressing piece is rotatably connected with a pressing plate. The pressing plate is fixedly connected with the insulating sleeve. Locking components are arranged on both sides of the metal guide piece. The locking components are rotatably connected with the fixing pressing piece. The metal guide piece is threadedly connected with a wire clamping plate. A universal ball is arranged at the other end of the wire clamping plate. The universal ball is connected with a wire connecting cylinder. The wire connecting cylinder is fixedly connected with a shock absorption component. The shock absorption component is rotatably connected with a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are detachably connected with the lightning protection insulator body.

[0006] Preferably, fixing clips are arranged on both sides of the fixing pressing piece. The fixing clips are rotatably connected with limiting clamping plates. Limiting grooves are formed in the limiting clamping plates.

[0007] Preferably, the locking component includes a fixing column fixedly connected with the metal guide piece. The fixing column is fixedly connected with a limiting block. Limiting springs are fixedly connected to both sides of the limiting block. The other ends of the limiting springs are fixedly connected with a trapezoidal blocking block. The trapezoidal blocking block is fixedly connected with a blocking column.

[0008] Preferably, the bolt is threadedly connected with a nut.

[0009] Preferably, fixed grooves are formed on both sides of the wire connection cylinder, and connection blocks are fixedly connected to the fixed grooves, and shock-absorbing sleeves are fixedly connected to the connection blocks.

[0010] Preferably, the shock-absorbing assembly includes a shock-absorbing sleeve fixedly connected to the wire connection cylinder. An expansion rod is connected inside the shock-absorbing sleeve. The expansion rod is rotatably connected to a connecting rod, and the connecting rod is rotatably connected to a clamping plate.

[0011] Preferably, arc-shaped holes adapted to the insulating sleeve are formed on one side of each of the first clamping plate and the second clamping plate. A T-shaped groove is formed on the inner side wall of the first clamping plate, and a T-shaped baffle is fixedly connected to the inner side wall of the second clamping plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In this solution, by providing a universal ball, the universal ball connects the wire clamping plate and the metal guide piece, which can reduce the vibration transmitted from the wire clamping plate to the metal guide piece. Telescopic springs are arranged in the shock-absorbing sleeves connected to both sides of the wire connection cylinder. The telescopic springs can disperse the vibration transmitted by the wire connection cylinder through shaking, effectively reducing the vibration feeling transmitted to the lightning protection insulator and reducing the risk of loosening of the bolts.

[0014] 2. In this solution, by providing a fixed pressing piece, the nut is located between the metal guide piece and the fixed pressing piece. The fixed pressing piece is connected to a limiting clamping plate. When the limiting clamping plate rotates to be adapted to the fixed column, the metal guide piece and the fixed pressing piece will be fixed. The pressing plate is fixedly connected to the insulating sleeve, which plays a role in offsetting the pulling force generated by vibration and reflects the role of dispersing vibration, preventing the loosening of the connection between the metal guide piece and the wire clamping plate due to vibration.

[0023] Refer to Figures 1 to 6 , a lightning protection insulator for preventing installation looseness, including a lightning protection insulator body 1, one end of the lightning protection insulator body 1 is fixedly connected with an insulating sleeve 2, one end of the insulating sleeve 2 is fixedly connected with a metal guide piece 3, a fixed pressing piece 4 is arranged on the surface of the metal guide piece 3, one end of the fixed pressing piece 4 is rotatably connected with a pressing plate 5.

[0024] It should be noted that: the fixed pressing piece 4 is rotatably connected with the pressing plate 5, which is convenient for flipping the fixed pressing piece 4 and facilitating the installation of the nut 14.

[0025] The pressing plate 5 is fixedly connected with the insulating sleeve 2, locking components are arranged on both sides of the metal guide piece 3, and the locking components are rotatably connected with the fixed pressing piece 4. Further, the locking components include a fixed column 15 fixedly connected with the metal guide piece 3, the fixed column 15 is fixedly connected with a limit block 16, limit springs 17 are fixedly connected to both sides of the limit block 16, the other ends of the limit springs 17 are fixedly connected with a trapezoidal blocking block 18, and the trapezoidal blocking block 18 is fixedly connected with a blocking column 19.

[0026] It should be noted that: the trapezoidal blocking block 18 is pressed into the limit groove in the limit clamping plate 13 through the limit spring 17. Since the trapezoidal blocking block 18 is connected with the blocking column 19, the metal guide piece 3 connected to the fixed column 15 can be tightly connected with the fixed pressing piece 4, preventing the nut 14 from loosening due to vibration.

[0027] The metal guide piece 3 is connected with a wire clamping plate 7 through a bolt 6. Further, the bolt 6 is threadedly connected with a nut 14.
