[0003] In the prior art, CN222126361U discloses a primary and secondary fusion pole-mounted switch that is easy to maintain. The primary and secondary fusion pole-mounted switch can swing to adjust to a suitable angle for maintenance personnel to work. However, the primary and secondary fusion pole-mounted switch cannot rotate, which makes it inconvenient for maintenance personnel to perform all-directional maintenance on the primary and secondary fusion pole-mounted switch. At the same time, when the height of the primary and secondary fusion pole-mounted switch body is high compared to the height of the maintenance personnel, it is impossible to adjust the height of the primary and secondary fusion pole-mounted switch body to facilitate maintenance. Therefore, we disclose a primary and secondary fusion pole-mounted switch to meet people's needs. Utility Model Content

[0021] 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.

[0022] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows:

[0023] A primary and secondary fusion column-mounted switch includes a mounting column 3. A rectangular groove 12 is formed on one inner wall of the mounting column 3. A mounting hole is formed on the bottom inner wall of the rectangular groove 12. A screw 14 is rotatably installed in the mounting hole. The top end of the screw 14 is rotatably installed on the top inner wall of the rectangular groove 12. The bottom end of the screw 14 extends to the outside of the mounting hole and is fixedly installed with a rotating block 13. A movable block 15 is threaded onto the screw 14 and is slidably installed in the rectangular groove 12. The side of the movable block 15 extends to the outside of the rectangular groove 12 and is fixedly installed with a movable plate 2. A mounting plate 16 is installed on the movable plate 2 through a rotating mechanism. The primary and secondary fusion column-mounted switch body 1 is fixedly installed on the top of the mounting plate 16.

[0024] The rotating mechanism includes a rectangular cavity 19 opened on the movable plate 2. A round shaft 10 is rotatably mounted on the bottom inner wall of the rectangular cavity 19. The top end of the round shaft 10 passes through the top inner wall of the rectangular cavity 19 and is fixedly mounted on the bottom of the mounting plate 16. A worm gear 20 is fixedly sleeved on the round shaft 10. A worm 18 is meshed on one side of the worm gear 20.

[0025] With the above structure: rotating the knob causes the rotating rod 11 to rotate, which in turn drives the worm gear 18 to rotate, which in turn drives the worm wheel 20 to rotate, thereby causing the round shaft 10 to rotate. The rotation of the round shaft 10 causes the mounting plate 16 and the primary and secondary fusion column switch body 1 to rotate. The rotation of the primary and secondary fusion column switch body 1 facilitates maintenance on both sides of the primary and secondary fusion column switch body 1. Rotating the rotating block 13 causes the screw 14 to rotate, thereby adjusting the position of the primary and secondary fusion column switch body 1 to meet maintenance needs at different heights.

[0026] like Figure 4 As shown, the rotating mechanism includes two rotating rods 11. The ends of the two rotating rods 11, close to each other, are fixedly mounted to both ends of a worm gear 18. Circular holes and circular grooves are respectively provided on the inner walls of both sides of the rectangular cavity 19. One end of one rotating rod 11 passes through the circular hole and is fixedly mounted with a knob, while one end of the other rotating rod 11 is rotatably mounted in the circular groove. The circular grooves and holes facilitate limiting the rotation of the two rotating rods 11, allowing them to only rotate. The knob facilitates the rotation of the rotating rods.

[0027] like Figure 1 and Figure 3 As shown, two mounting sleeves 7 are fixedly installed on the side of the mounting column 3. A mounting shaft 8 is rotatably installed inside each mounting sleeve 7. Connecting blocks 9 are fixedly installed at both ends of the mounting shaft 8. Clamps 6 are fixedly installed on the sides of the two connecting blocks 9 away from the mounting column 3. Threaded holes are provided on the inner walls of each mounting sleeve 7, and fixing bolts 5 are threaded into each of the two threaded holes. Multiple slots 17 are provided on one side of each fixing bolt 5 on the annular side of the mounting shaft 8, with one end of the fixing bolt 5 extending into one of the slots 17. By turning the two fixing bolts 5 to move them out of the slots 17, the mounting sleeves 7 and mounting shaft 8 lose their limiting position. Then, rotating the mounting column 3 allows the primary and secondary fusion column switch body 1 to swing, thereby adjusting the primary and secondary fusion column switch body 1 to the side of the maintenance personnel. Then, rotating the fixing bolts 5 in the opposite direction allows them to enter one of the slots 17, thus fixing the position of the mounting sleeve 7.

[0028] like Figure 1 As shown, the sides of the two mounting sleeves 7 that are far apart from each other contact the sides of the two connecting blocks 9 that are close to each other. The advantage of this arrangement is that the mounting sleeves 7 can only rotate and cannot move up and down.

[0029] like Figure 1As shown, a dustproof plate 4 is fixedly sleeved on the movable block 15. The length of the dustproof plate 4 is equal to twice the length of the rectangular groove 12, and the distance between the top of the dustproof plate 4 and the top of the movable block 15 is equal to the distance between the bottom of the dustproof plate 4 and the bottom of the movable block 15. The side of the dustproof plate 4 contacts the side of the mounting column 3. By setting the dustproof plate 4, the rectangular groove 12 can be sealed, thereby preventing dust from entering.

[0030] Working principle:

[0031] In use, the device can be installed on a utility pole using the clamp 6. When maintenance is required on the primary and secondary fusion pole-mounted switch body 1, the two fixing bolts 5 are turned to move it out of the two slots 17, causing the mounting sleeve 7 and mounting shaft 8 to lose their limit. Then, rotating the mounting column 3 will allow the primary and secondary fusion pole-mounted switch body 1 to swing, thereby adjusting the primary and secondary fusion pole-mounted switch body 1 to the side of the maintenance personnel. Then, the fixing bolts 5 are turned in the opposite direction to move it into one of the slots 17, thereby fixing the position of the mounting sleeve 7. By turning the knob, the rotating rod 11 can be rotated. The rotation of the rotating rod 11 drives the worm gear 18 to rotate, which in turn drives the worm wheel 20 to rotate, thereby causing the round shaft 10 to rotate. The rotation of the round shaft 10 drives the mounting plate 16 and the primary and secondary fusion pole-mounted switch body 1 to rotate. The primary and secondary fusion pole-mounted switch body 1 rotates, making it convenient to maintain both sides of the primary and secondary fusion pole-mounted switch body 1.

[0032] When it is found that the height of the primary and secondary fusion column switch body 1 is too high, the screw 14 can be rotated by rotating the rotating block 13. The moving block 15 is limited by the rectangular slot 12 and can only slide up and down. Therefore, the rotation of the screw 14 causes the moving block 15 to move. The movement of the moving block 15 drives the moving plate 2, the round shaft 10, the mounting plate 16 and the primary and secondary fusion column switch body 1 to move, thereby adjusting the position of the primary and secondary fusion column switch body 1 to meet the maintenance needs of different heights.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
