[0026] Embodiment

[0027] As Figures 1 to 4The utility model provides a kind of power transmission line fixing device, including circular compression ring 1, two line clamps 2 and two locking clamps 3 are provided on circular compression ring 1, two line clamps 2 and locking clamp 3 are all fastened by screw 4.Circular compression ring 1 is used to lock solid effect to insulator string, is realized by locking two locking clamps 3, and line clamp 2 is used for fixing on power transmission line effect.Further, since screw 4 on it is long-term exposed in environment, first protective sleeve 5 for rust prevention is inserted and arranged on line clamp 2, second protective sleeve 6 for rust prevention is inserted and arranged on locking clamp 3, to facilitate the protection of screw 4, thereby prolong the service life of screw 4, avoid that screw 4 appears rust and causes line clamp 2 and locking clamp 3 to be not opened.

[0028] Specifically, as shown in Figure 1 and Figure 2 The first protective sleeve 5 and the second protective sleeve 6 are both square in shape, which can better wrap the line clamp 2 or the locking clamp 3 and improve the sealing performance. The first protective sleeve 5 is detachably installed on the first bottom plate 7, and the second protective sleeve 6 is detachably installed on the second bottom plate 8. The detachable installation facilitates the replacement and disassembly in the later period, and the installation process is also convenient.

[0029] As shown in Figure 3 The first bottom plate 7 and the second bottom plate 8 are both provided with a sleeve groove 9, and the first protective sleeve 5 and the second protective sleeve 6 are both inserted into the sleeve groove 9 to achieve waterproof and moisture-proof effects. The sleeve groove 9 is in the shape of an inverted T, and the bottom of the first protective sleeve 5 or the second protective sleeve 6 is provided with a T-shaped clamping block 10 that is in clamping cooperation with the sleeve groove 9. When the clamping block 10 is in close contact with the sleeve groove 9, the local tightness is ensured.

[0030] Further, the clamping block 10 is made of soft material, such as rubber, silicone, plastic, etc. When the first protective sleeve 5 or the second protective sleeve 6 is inserted into the sleeve groove 9, the clamping block 10 will be plastically deformed due to the tight extrusion caused by the interference fit, which improves the sealing effect and further improves the waterproof and moisture-proof effects.

[0031] Further, a drainage hole 11 is provided on one end of the side wall of the sleeve groove 9 to drain the water in the sleeve groove 9 and prevent water accumulation.

[0032] As shown in Figure 4As shown, the fastening effect of the first protective shell 5 and the second protective shell 6 is realized through the plug-in column 12 arranged thereon. The plug-in column 12 is arranged on the first bottom plate 7 and the second bottom plate 8, and is in cooperation with the plug-in slot 13. The plug-in column 12 is in an interference sliding fit in the plug-in slot 13, and can be installed by using a small hammer to knock during installation, thereby realizing a tight connection effect and enabling long-term stability.

[0033] Further, the limiting elastic piece 14 is arranged on the two end side walls of the plug-in column 12, and the limiting slot 15 is arranged on the two end side walls of the plug-in slot 13 and is in clamping cooperation with the limiting elastic piece 14. During use, when the plug-in column 12 is in sliding fit in the plug-in slot 13, the limiting elastic piece 14 is elastically inserted into the limiting slot 15, thereby realizing limiting and fixing effect. When replacement is needed, it can only be removed by destruction, and then a new one is used, which is beneficial to avoid the case that the old one is used again and the sealing is not firm. The structure shape is implemented as Figure 4 As shown, the limiting elastic piece 14 can be arranged in an L-shaped structure, and the limiting slot 15 is arranged in an inverted L-shaped structure.

[0034] In summary, by arranging the first protective shell 5 and the second protective shell 6, the corrosion of the wire clamp 2, the locking clamp 3 and the screw 4 caused by long-term exposure to the environment is effectively avoided, the service life of the screw 4 connection structure is improved, and at the same time, since the plug-in detachable installation mode is adopted, the later disassembly work is facilitated, and the convenience of the disassembly process is improved.
