The positioning mechanism comprises a base, a movable plate, and a clamping plate. The movable plate is rotatably mounted on the top of the base, and the clamping plate is slidably disposed between the base and the movable plate. The movable plate has equally spaced strip-shaped holes inside, and a protrusion is fixedly mounted on the upper surface of the clamping plate. The protrusion is slidably disposed inside the strip-shaped holes, and the partition block overlaps the surface of the movable plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a winding assembly for a photovoltaic transformer, including an insulating frame 1, a high-voltage winding 2 movably mounted on the inner side of the insulating frame 1, a positioning mechanism 3 provided at the bottom of the insulating frame 1, a triangular prism 5 fixedly mounted on the top of the insulating frame 1, and a partition block 4 fixedly mounted on the outer wall of the triangular prism 5. The positioning mechanism 3 includes a base 31, a movable plate 32, and a clamping plate 39. The movable plate 32 is rotatably mounted on the top of the base 31, and the clamping plate 39 is slidably disposed between the base 31 and the movable plate 32. The movable plate 32 has equally spaced slotted holes 38 inside, and a protrusion 310 is fixedly mounted on the upper surface of the clamping plate 39. The protrusion 310 is slidably disposed inside the slotted holes 38. The partition block 4 overlaps the surface of the movable plate 32, and the triangular prism 5 penetrates the movable plate 32 and is inserted into the interior of the base 31. The shape of the edge of the clamping plate 39 is adapted to the triangular prism 5.

[0019] The specific setup and function of this embodiment are described below. This component uses an insulating frame 1 as its base. A high-voltage winding 2, movably mounted inside the insulating frame 1, is used to realize the energy conversion function of the photovoltaic transformer. A positioning mechanism 3 at the bottom of the insulating frame 1 is responsible for positioning and fixing the overall structure. The base 31 in the positioning mechanism 3 provides the mounting support foundation for the entire component. When positioning the insulating frame 1 is required, the triangular prism 5 is inserted into the base 31. Then, the movable plate 32 is rotated. Utilizing the sliding engagement between the strip hole 38 and the protrusion 310 on the upper surface of the clamping plate 39, the clamping plate 39 is moved towards the center of the base 31, completing the clamping of the triangular prism 5. The separator block 4 overlaps the surface of the movable plate 32, further assisting in defining the position of the insulating frame 1, ultimately completing the winding assembly. Precise positioning and fixation: The positioning mechanism 3, through the coordinated action of the base 31, movable plate 32, and clamping plate 39, combined with the sliding cooperation of the strip hole 38 and the protrusion 310, achieves flexible clamping and positioning of the insulating frame 1. It is convenient to operate and has strong positioning stability. The structure of the triangular prism 5 penetrating the movable plate 32 and inserting into the base 31, combined with the shape adaptation design of the clamping plate 39 and the triangular prism 5, greatly improves the anti-displacement ability of the insulating frame 1 after installation, and avoids structural displacement caused by vibration during long-term operation. The separator 4 can not only overlap on the movable plate 32 to help fix the insulating frame 1, but also physically separate the high-voltage winding 2 from the surrounding components, reduce electromagnetic interference, ensure the energy conversion efficiency of the high-voltage winding 2, and thus improve the operational stability and service life of the entire photovoltaic transformer.

[0020] Example 2: Figure 1 and Figure 2 As shown, an extension block 33 is fixedly installed at the edge of the movable plate 32, and a lead screw 34 is threadedly connected inside the extension block 33. A positioning block 35 is fixedly installed at the edge of the base 31, and a driven block 36 is rotatably installed on the upper surface of the positioning block 35. One end of the lead screw 34 is rotatably connected inside the driven block 36. A limit screw assembly 311 is fixedly installed on the upper surface of the base 31. The nut of the limit screw assembly 311 overlaps the upper surface of the movable plate 32. An arc-shaped hole 37 is provided at the junction of the movable plate 32 and the limit screw assembly 311. The arc-shaped hole 37 and the strip hole 38 are located at the trisection line of the movable plate 32.

[0021] The overall effect of this embodiment is that the extension block 33 on the edge of the movable plate 32 is threadedly connected to the lead screw 34, the positioning block 35 supports the driven block 36, and when the lead screw 34 is rotated, the extension block 33 drives the movable plate 32 to rotate around the base 31 under the action of the thread. The limiting screw assembly 311 passes through the arc-shaped hole 37, and its nut can not only prevent the movable plate 32 from falling off, but also press and fix the movable plate 32. The threaded cooperation between the extension block 33 and the lead screw 34 makes the rotation adjustment of the movable plate 32 more precise and labor-saving, and facilitates quick clamping and positioning. The positioning block 35 and the driven block 36 provide stable support for the lead screw 34, avoiding deviation or jamming during transmission and improving structural stability. The nut of the limiting screw assembly 311 can quickly lock the movable plate 32 to prevent loosening due to vibration during operation and enhance positioning reliability.

[0022] The method of use and working principle of this device: Fix the base 31 in the designated position, install the high voltage winding 2 inside the insulating frame 1, insert the triangular prism 5 at the top of the insulating frame 1 through the movable plate 32 and into the base 31, so that the partition block 4 overlaps the surface of the movable plate 32, rotate the lead screw 34, and under the support of the threaded engagement between the extension block 33 and the lead screw 34 and the driven block 36 on the positioning block 35, drive the movable plate 32 to rotate around the base 31. The movable plate 32 drives the clamping plate 39 to move towards the center of the base 31 through the sliding engagement between the internal strip hole 38 and the protrusion 310 on the clamping plate 39, until the clamping plate 39 and the triangular prism 5 are tightly fitted and clamped. At this time, the limiting screw assembly 311 on the base 31 passes through the arc hole 37 of the movable plate 32, tighten the nut of the limiting screw assembly 311, and make it overlap the upper surface of the movable plate 32 to achieve fixation.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
