[0002] Outdoor transformers are electrical devices designed for outdoor environments and used to change AC voltage levels. Outdoor transformers require the use of fixed supports, which are support structures used to stably fix the transformer in a designated location. Their core functions are to prevent tipping, displacement, and ensure safe distances. They must also be compatible with the installation type of the outdoor transformer.

[0003] For a transformer installed between two poles, the mounting bracket is usually installed by first installing clamps on the two poles, then installing crossarms on the two clamps, and finally installing the transformer on the crossarms. Bolts and nuts are required for all assembly processes.

[0004] However, the aforementioned fixing brackets require workers to climb up and down the utility poles multiple times during installation, making the operation cumbersome. Furthermore, the crossarm installation may not be level, depending on the perfect alignment of the two clamps, requiring strict control by the workers, making the operation inconvenient. Additionally, the fixing brackets cannot be adjusted in length to accommodate different distances between two utility poles, limiting their applicability. Therefore, a fixing bracket for outdoor transformers is proposed. Utility Model Content

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.

[0024] This utility model provides a technical solution: such as Figure 1 - Figure 6 The outdoor transformer mounting bracket shown includes V-shaped housing 1 arranged symmetrically at the front and back, each of the two V-shaped housing 1 is provided with a column clamping assembly, and a fixing mechanism for supporting and installing the transformer is provided between the two V-shaped housing 1.

[0025] The fixing mechanism includes a bearing frame 2, which is set between two V-shaped housings 1. Both sides of the bearing frame 2 are fixedly connected to connecting rods 5. The outer walls of the two connecting rods 5 are symmetrically fitted with concave steel 6. The two concave steel 6 located in front are fixedly connected to the rear end of the V-shaped housing 1 located in front, and the two concave steel 6 located in the rear are fixedly connected to the front end of the V-shaped housing 1 located in the rear. Each concave steel 6 is provided with a locking component between it and the adjacent connecting rod 5. An elastic mechanism is provided between the two V-shaped housings 1 and the two connecting rods 5.

[0026] The column assembly includes two fastening bolts 8, which are threaded through and connected to both ends of the V-shaped housing 1. The outer walls of the two fastening bolts 8 are slidably fitted with V-shaped fixing plates 9, and the outer walls of the two fastening bolts 8 are threaded with fastening nuts 7.

[0027] The locking assembly includes an internally threaded tube 13, which is connected to the side wall of the concave steel 6. A stud 11 is threadedly connected to the inner wall of the internally threaded tube 13. One end of the stud 11 is in contact with the side wall of the connecting rod 5, and the other end of the stud 11 is fixedly connected to a screwing block 4.

[0028] The elastic mechanism includes four connecting posts 10 and four cylindrical slides 14. One end of each of the four connecting posts 10 is fixedly connected to the inner wall of the two V-shaped housings 1 in pairs. The four cylindrical slides 14 are respectively opened at the front and rear ends of the two connecting rods 5. The four connecting posts 10 slide in cooperation with the four cylindrical slides 14 respectively, and the other end of each of the four connecting posts 10 is fixedly connected to a spring 12 between it and its corresponding cylindrical slide 14.

[0029] The upper end of the supporting frame 2 has multiple mounting holes 3, which are arranged in a linear array.

[0030] Washers 15 are slidably fitted on the outer walls of the two fastening bolts 8, and the two washers 15 are respectively attached between the two fastening nuts 7 and the V-shaped fixing plate 9.

[0031] Working principle: The mounting bracket for this outdoor transformer is as follows: Figure 1 As shown, first, hold the V-shaped housing 1 with both hands and bring the two V-shaped housings 1 close to each other. During the process, each V-shaped housing 1 will drive the connecting post 10 connected to it to slide in its corresponding cylindrical groove 14 and squeeze the spring 12. During the process, each V-shaped housing 1 will also drive the two concave steels 6 connected to it to slide outside the two connecting rods 5 until the two V-shaped housings 1 can be inserted between the two wire posts. Then, slowly release the two V-shaped housings 1. Under the action of the spring 12, the V-face of the two V-shaped housings 1 will abut against the outer wall of the two wire posts respectively, and can accommodate different spacing between the two wire posts.

[0032] Next, pass two fastening bolts 8 through both ends of a V-shaped housing 1, and align a V-shaped fixing plate 9 from the outside of the corresponding post with the V-shaped housing 1. Then, slip the V-shaped fixing plate 9 over the two fastening bolts 8. Next, place two washers 15 over the two fastening bolts 8, and finally screw two fastening nuts 7 over the two fastening bolts 8. Do not tighten the nuts 7 completely; simply allow the V-shaped fixing plate 9 to remain in contact with the post. Repeat the same process for the other V-shaped fixing plate 9. The final result is as follows: Figure 6 As shown.

[0033] Finally, workers can use existing climbing tools to climb onto a utility pole, pushing a concave steel 6 upwards during the climb. The entire fixing bracket will then slide between the two utility poles. It should be noted that the V-shaped housing 1, affected by the spring 12, has no effect on the contact force between itself and the utility pole, and will not affect the workers' upward pushing of the entire fixing bracket. Once the fixing bracket reaches the appropriate height, all the fastening nuts 7 are tightened using tools. The washers 15 will fit tightly between the V-shaped fixing plate 9 and the fastening nuts 7, preventing the fastening nuts 7 from loosening. At this point, the V-shaped housing 1 and the V-shaped fixing plate 9 are fixed to the corresponding utility poles. Then, the multiple tightening blocks 4 are rotated sequentially, causing each stud 11 to rotate towards the connecting rod 5 within its corresponding internal thread tube 13, until the ends of all studs 11 are tightly abutted against the side wall of the connecting rod 5, thereby improving the stability of the load-bearing frame 2 and the two connecting rods 5. The outdoor transformer can then be installed using the mounting holes 3 on the load-bearing frame 2.

[0034] It should be noted that the existing anti-fall clamp can be installed on the outer wall of the utility pole below the V-shaped housing 1 and the V-shaped fixing plate 9 to further improve the stability of the fixing bracket.

[0035] It should be noted that the fixed bracket can be pre-fixed between two utility poles and is suitable for two utility poles with different spacing. The fixed bracket is easy to push and move upward as the worker climbs. During the process, the fixed bracket is affected by the spring, and there is a certain friction between the fixed bracket and the utility pole, which makes it difficult for it to slide down automatically. This reduces the number of times the worker has to climb up and down the utility pole. In addition, the fixed bracket can be kept horizontal without strict control during installation, which facilitates operation.
