[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3The waterproof transformer includes a mounting plate 1, on which a waterproof cover 3 is provided. Inside the waterproof cover 3, four equidistant positioning rods 12 are fixedly installed relative to the upper end of the mounting plate 1. A fixing plate 11 is sleeved on the outer wall of the four positioning rods 12. A transformer 17 is integrally fixedly installed on the upper end of the fixing plate 11. Four second threaded rods 14 are equidistantly installed on the side wall of the fixing plate 11 and are rotatably mounted on the mounting plate 1. Limiting plates 13 are sleeved on the outer wall of the four second threaded rods 14, and the bottom end of the limiting plates 13 is in contact with the fixing plate 11.

[0021] The bottom of the waterproof cover 3 has a waterproof groove, and the upper end of the mounting plate 1 is fixedly installed with an annular sealing strip 2 set in the waterproof groove. Two symmetrically arranged wiring terminals 4 are also fixedly installed on the two side walls of the waterproof cover 3.

[0022] Two pairs of symmetrically arranged first threaded rods 6 are fixedly installed on the mounting plate 1, and the two pairs of first threaded rods 6 are respectively set in two pairs of sliding holes 5. The two first threaded sleeves 7 are both sleeved on the outer wall of the two first threaded rods 6 through internal threads.

[0023] A rotating shaft 8 is fixedly installed on the upper end of the first threaded sleeve 7. A fixed plate 9 is integrally fixedly installed on the outer wall of the rotating shaft 8. The fixed plate 9 moves towards the terminal 4 and comes into contact with the terminal 4, fixing the terminal 4 on the mounting plate 1. At the same time, the waterproof cover 3 is fixed on the mounting plate 1 through the terminal 4 to prevent water from entering the waterproof cover 3. A rotating ring 10 is fixedly installed on the upper end of the rotating shaft 8.

[0024] The outer walls of the four second threaded rods 14 are all fitted with second threaded sleeves 16 by threads, and the four second threaded sleeves 16 are all set on the upper ends of the four limiting plates 13. By rotating the second threaded sleeves 16, the second threaded sleeves 16 push the limiting plates 13 to move towards the fixing plate 11, fixing the fixing plate 11 on the mounting plate 1. At the same time, the positioning rods 12 are used to position the fixing plate 11, preventing the fixing plate 11 from moving laterally under the limitation of the limiting plates 13. Limiting rings 15 are fixedly installed on the upper ends of the four second threaded rods 14.

[0025] It should be noted that the specific model and specifications of the waterproof cover 3 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0026] The functional principle of this utility model can be explained through the following operation methods:

[0027] In use, by rotating the rotating ring 10, the rotating ring 10 drives the rotating shaft 8 to rotate synchronously. The rotating shaft 8 drives the first threaded sleeve 7, which is fixedly installed at the bottom, to rotate on the first threaded rod 6, so that the fixed plate 9 moves towards the terminal 4 and comes into contact with the terminal 4, fixing the terminal 4 on the mounting plate 1. The terminal 4 limits the waterproof cover 3, and together with the sealing strip 2, isolates water on the outer wall of the waterproof cover 3.

[0028] The fixing plate 11 is precisely positioned by four positioning rods 12, and the second threaded sleeve 16 rotates on the second threaded rod 14, pushing the limiting plate 13 to move axially along the second threaded rod 14 toward the fixing plate 11, so that the limiting plate 13 and the fixing plate 11 are in contact and the fixing plate 11 is fixed on the mounting plate 1, which facilitates the installation of the mounting plate 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
