Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a new technical solution: a double protection tension composite insulator, including an insulator body 1, a first mounting plate 2 fixedly installed at one end of the insulator body 1, and a second mounting plate 3 fixedly installed at the other end of the insulator body 1, with mounting holes 4 opened on both the first mounting plate 2 and the second mounting plate 3.

[0026] The fixing mechanism is mounted on the first mounting plate 2 and includes two fixing plates 5 and two trapezoidal plates 6. The two fixing plates 5 are fixedly mounted on the lower surface of the first mounting plate 2. The interior of each fixing plate 5 is provided with a mounting groove 7. The lower end of each mounting groove 7 is provided with two sliding grooves 8. The two trapezoidal plates 6 are slidably mounted inside the two mounting grooves 7. The lower end of each trapezoidal plate 6 is fixedly mounted with a connecting rod 9. The two connecting rods 9 are fixedly mounted on the lower surface of the two trapezoidal plates 6 and on the inner wall of the two sliding grooves 8. The lower end of the two sliding grooves 8 extends to the lower end of the two fixing plates 5.

[0027] Furthermore, the fixing mechanism also includes two springs 10, which are respectively fixedly installed on the left inner wall of the two mounting slots 7, and the two springs 10 are respectively fixedly connected to the corresponding trapezoidal plates 6.

[0028] Furthermore, the upper surface of the second mounting plate 3 has two fixing grooves 12, which are respectively adapted to the two fixing plates 5.

[0029] Furthermore, by inserting the two fixing plates 5 into the two fixing slots 12 on the other insulator body 1, the two trapezoidal plates 6 are fixed thereto, thereby pre-fixing the two insulator bodies 1 in a simple way, which facilitates the tightening of the fixing bolts 11 later, reduces the difficulty of connecting the two insulator bodies 1, improves the installation efficiency of the insulator, and thus improves the utilization efficiency of the insulator.

[0030] Furthermore, annular plates 13 are fixedly installed on the outer surfaces of both ends of the insulator body 1.

[0031] Furthermore, two semi-annular plates 14 are slidably installed on the outer surface of the insulator body 1. The annular plate 13 slides in contact with the inner wall of the semi-annular plate 14. A fixing block 15 is fixedly installed at the front end of the upper surface of the lower semi-annular plate 14. A storage groove 16 is opened at the rear end of the upper surface of the lower semi-annular plate 14. A fixing rod 17 is fixedly installed on the left surface of the fixing block 15. A circular groove 18 is opened on the right inner wall of the storage groove 16. The upper semi-annular plate 14 is a mirror image of the lower semi-annular plate 14 after rotating 180 degrees.

[0032] Furthermore, by installing two semi-annular plates 14 at the connection between the two insulator bodies 1, the two fixing rods 17 are respectively inserted into the interior of the two circular grooves 18 to fix the two semi-annular plates 14. This allows the two semi-annular plates 14 to protect the connection between the two insulator bodies 1, preventing damage and affecting the connection and use of the two insulator bodies 1, thus improving the safety of the insulator.

[0033] Furthermore, a fixing bolt 11 is threaded onto the inner wall of the mounting hole 4.

[0034] Working Principle: When using this insulator and needing to increase the insulation length, one end of one insulator body 1 can be fixed to the tower, and the second mounting plate 3 on the other insulator body 1 can be fixed to the wire. The cable is then passed through the mounting hole 4 on the second mounting plate 3 and fixed. Next, the first mounting plate 2 on the latter insulator body 1 is aligned with the second mounting plate 3 on the former insulator body 1, and the two fixing plates 5 on the first mounting plate 2 are aligned with the two fixing slots 12 on the second mounting plate 3. The two fixing plates 5 are pushed into the two fixing slots 12. When the two fixing plates 5 enter the two fixing slots 12, the two trapezoidal plates 6 on the two fixing plates 5 are pressed into the corresponding mounting slots 7, compressing the springs 10 inside the corresponding mounting slots 7. The two fixing plates 5 continue downwards. When the first mounting plate 2 and the second mounting plate 3 are in contact, the position of the two mounting slots 7 reaches below the second mounting plate 3, the compression on the two trapezoidal plates 6 disappears, and the two springs 10 release the pressure. The trapezoidal plates 6 are pushed out, fixing the two fixing plates 5 into the two fixing slots 12, thus simply fixing the first mounting plate 2 and the second mounting plate 3. At this time, the fixing bolts 11 can be more easily installed into the mounting holes 4, thereby installing the first mounting plate 2 and the second mounting plate 3, connecting the two insulator bodies 1, reducing the installation difficulty of the two insulator bodies 1. After installation, the two semi-circular plates 14 can be pushed up and down, so that the receiving groove 16 on the upper semi-circular plate 14 aligns with the fixing block 15 on the lower semi-circular plate 14. Then, the two are respectively attached to the two insulator bodies 1, and the two semi-circular plates 14 are pushed into each other. The circular groove 18 on the lower fixing block 15 is pushed into the fixing rod 17 opened in the receiving groove 16 of the upper one, thereby fixing the two semi-circular plates 14 to the connection of the two insulator bodies 1, protecting the fixing mechanism at the connection and reducing the possibility of damage during use.
