[0002] Lightning arrester: An electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-on time, and often also the follow-on amplitude. Lightning arresters are sometimes also called overvoltage protectors and overvoltage limiters. In the daily installation and use of lightning arresters, lightning brackets are required to assist in the installation and use of lightning arresters.

[0003] For example, application number 202323334476.2 discloses a lightning protection bracket for a wire rope pole, comprising a fixed clamp, a column, and a cross bar, the fixed clamp being arranged at the lower part of the column, the cross bar being arranged in the middle and lower part of the column, and column insulators being arranged at both ends or either end of the cross bar, each of the columns being arranged in an L-shaped structure by an integral molding structure of a vertical beam and a cantilever beam, at least two fixed clamps being arranged at the lower part of the vertical beam, the fixed clamp connecting the two columns into an integral structure, a suspension insulator or a column insulator being arranged at the end of the cantilever beam, a plurality of mounting holes being arranged in the middle and lower part of each vertical beam above the fixed clamp, the cross bar being arranged on the two vertical beams through the mounting holes and bolts, a limiting frame being arranged on the mounting holes at the lowest parts of the two vertical beams through the mounting holes and bolts, a positioning plate being arranged at the top of the two vertical beams, and a lightning rod being arranged at either end of the positioning plate. The utility model combines the wire rope rack and the lightning protection rack into one, which not only has a good lightning protection effect, but also is easy to install and use, has a high tolerance strength, and effectively ensures the normal operation of the power line.

[0004] However, when this type of lightning protection bracket for a power pole is used, although it can effectively perform lightning protection operations on the power pole, it is often still relatively cumbersome to install the lightning arrester through bolts. The lightning arrester is not easy to install on the bracket. When the lightning arrester is bolted to perform high-altitude operations, the installer needs to repeatedly tighten the bolts, which increases the safety of the installer's high-altitude operations and reduces the efficiency of installing the lightning arrester on the bracket.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a lightning protection bracket for a wire pole is proposed. Utility Model Content

[0028] Furthermore, a mounting groove 214 is provided at the connection portion between the top of the mounting box 14 and the arrester body 13, and the connecting rod 211 forms a telescopic structure with the mounting box 14 through the pull button 212 and the spring 213, which is conducive to the movement of the pull button 212 through the connection of the spring 213, driving the connecting rod 211 to perform reciprocating telescopic movement along the outer wall of the mounting box 14, thereby realizing the control operation of locking and fixing the arrester body 13.

[0029] Furthermore, a limiting groove 215 is provided at the connection portion between the outer wall of the bracket body 12 and the arrester body 13. The arrester body 13 forms a sliding structure with the mounting box 14 through the bracket body 12 and the limiting groove 215, which is conducive to the arrester body 13 sliding along the inner wall of the limiting groove 215, driving the arrester body 13 and the mounting box 14 to be engaged and fixed, thereby realizing the control operation of convenient installation between the bracket body 12 and the arrester body 13.

[0030] Furthermore, a fixing groove 216 is provided at the connection portion between the outer wall of the arrester body 13 and the connecting rod 211. The arrester body 13 forms an installation structure with the installation box 14 through the connecting rod 211 and the fixing groove 216, which is conducive to the connecting rod 211 sliding along the inner wall of the fixing groove 216, driving the arrester body 13 and the installation box 14 to be engaged and fixed, thereby realizing the control operation of plugging and installing the arrester body 13 on the bracket.

[0031] Furthermore, two groups of fixing boxes 15 are provided, and the positions of the two groups of fixing boxes 15 are symmetrical about the central axis of the installation box 14 , which is beneficial for controlling the installation stability of the lightning arrester body 13 through the provision of the two groups of fixing boxes 15 .

[0032] Example 2: Figure 1 、 Figure 2 and Figure 5 As shown, the utility model proposes a lightning protection bracket for a wire pole. Compared with the first embodiment, as another embodiment of the utility model, the outer wall of the connecting frame 11 is fixedly connected with a fixing block 3 that fits the outer wall of the bracket body 12. The inner wall of the fixing block 3 is threadedly connected with a buckle 31 that runs through the outer wall of the bracket body 12. The outer wall of the buckle 31 is provided with an outer screw 32. The connection part between the inner side wall of the fixing block 3 and the outer screw 32 is provided with an inner screw 34. The connection part between the outer wall of the bracket body 12 and the buckle 31 is provided with a card groove 33. When working, by setting the buckle 31, it is beneficial to install the lightning arrester through the bracket to improve the installation. The bracket body 12 is installed more efficiently on the top of the connecting frame 11 and the installation personnel can reduce the tediousness of the bracket installation. When the bracket needs to be pre-installed, the bracket body 12 can be inserted into the inner wall of the fixing block 3 first, and the bracket body 12 is connected through the slot 33 so that the bracket body 12 passes through the outer wall of the buckle 31, and the buckle 31 is rotated.

[0033] Furthermore, the outer wall profile of the fixing block 3 is in a "U" shape, and the outer wall profile of the fixing block 3 is adapted to the outer wall profile of the bracket body 12. The bracket body 12 forms a snap-fit ​​structure with the fixing block 3 through the buckle 31 and the slot 33, which is conducive to the buckle 31 sliding along the inner wall of the slot 33, driving the bracket body 12 and the fixing block 3 to be snap-fitted and fixed, thereby achieving the effect of improving the pre-installation efficiency of the bracket body 12 on the connecting frame 11.

[0034] Furthermore, the length of the slot 33 is greater than the length of the buckle 31, and the outer wall profile of the buckle 31 is in a "T" shape. The buckle 31 forms a rotating structure with the fixed block 3 through the outer spiral 32 and the inner spiral 34, which is conducive to driving the buckle 31 to rotate through the connection between the outer spiral 32 and the inner spiral 34, and making the cross-section of the top of the buckle 31 and the cross-section of the bracket body 12 perpendicular to each other, thereby playing the role of clamping and fixing the bracket body 12.

Under the connection of the spring 213, the connecting rod 211 is driven to perform telescopic movement along the inner wall of the installation box 14, and at the same time, the connecting rod 211 is driven to slide into the inner wall of the fixing groove 216, which plays a role in locking and fixing the lightning arrester body 13, thereby realizing the control operation of plugging and installing the lightning arrester body 13 on the bracket.

[0036] Finally, when installing the lightning arrester through the bracket, in order to improve the installation efficiency of the bracket body 12 on the top of the connecting frame 11 and reduce the tediousness of the bracket installation for the installer, when the bracket needs to be pre-installed, the bracket body 12 can be inserted into the inner wall of the fixed block 3 first, and through the connection of the card slot 33, the bracket body 12 is made to pass through the outer wall of the buckle 31, and the buckle 31 is rotated. Under the threaded connection of the outer spiral 32 and the inner spiral 34, the buckle 31 is driven to rotate, and the cross-section of the top of the buckle 31 is set perpendicular to the cross-section of the bracket body 12, which plays a role in locking and fixing the bracket body 12, thereby improving the pre-installation efficiency of the bracket body 12 on the connecting frame 11.
