Detailed Implementation

[0014] 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.

[0015] Example 1 Please refer to Figure 1-6 As shown, this utility model provides an outdoor voltage transformer, including a fixed base 1 and a voltage transformer body 10. The top of the fixed base 1 is provided with a mounting seat 3, and the bottom of the voltage transformer body 10 is provided with a connecting seat 11 adapted to the mounting seat 3. The inner side of the mounting seat 3 is provided with a pre-positioning mechanism to facilitate the installation of the voltage transformer body 10. Two sets of connecting plates 7 are symmetrically provided on the outer ring of the mounting seat 3 near the top. Two sets of protruding plates 12 are symmetrically provided on the outer ring of the connecting seat 11. The two sets of protruding plates 12 are respectively connected and fixed to the two sets of connecting plates 7 through a fixing mechanism that facilitates disassembly and assembly.

[0016] Specifically, when the outdoor voltage transformer is in operation, the connecting seat 11 at the bottom of the voltage transformer body 10 is first aligned with the mounting seat 3 at the top of the fixed base 1. The voltage transformer body 10 can be initially positioned by the pre-positioning mechanism on the inner side of the mounting seat 3, so that the connecting seat 11 is accurately placed on the mounting seat 3. At this time, the two sets of protruding plates 12 on the outer ring of the connecting seat 11 are respectively attached to the two sets of connecting plates 7 on the outer ring of the mounting seat 3. Then, the two sets of protruding plates 12 and the two sets of connecting plates 7 can be connected and fixed by the fixing mechanism that is easy to disassemble and assemble, thereby completing the installation and fixing of the voltage transformer body 10. When disassembling, the protruding plates 12 and the connecting plates 7 can be separated by releasing the locking of the fixing mechanism, so as to facilitate the disassembly of the voltage transformer body 10. Thus, through the above structure, the installation efficiency and maintenance convenience of the voltage transformer are improved, and the positioning is accurate and the installation is stable.

[0017] The pre-positioning mechanism includes a contact plate 8. The contact plate 8 is located on the inner side of the mounting base 3. The bottom of the contact plate 8 is connected to the bottom of the inner side of the mounting base 3 via a spring 9. Two sets of vertical grooves 4 are symmetrically opened on the side wall of the mounting base 3. A movable groove 5 is opened on one side of the bottom of each set of vertical grooves 4. A positioning groove 6 is opened at the end of each set of movable grooves 5 away from the vertical grooves 4. When the outdoor voltage transformer is working, the connecting seat 11 at the bottom of the voltage transformer body 10 is first aligned with the mounting base 3 at the top of the fixed base 1. The voltage transformer body 10 can be initially positioned by the pre-positioning mechanism inside the mounting base 3. This allows the connector 11 to be accurately placed on the mounting base 3. At this time, the two sets of protruding plates 12 on the outer ring of the connector 11 are respectively attached to the two sets of connecting plates 7 on the outer ring of the mounting base 3. Then, the two sets of protruding plates 12 and the two sets of connecting plates 7 can be connected and fixed by a fixing mechanism that is easy to disassemble and assemble, thereby completing the installation and fixing of the voltage transformer body 10. When disassembling, the protruding plates 12 and the connecting plates 7 can be separated by releasing the locking of the fixing mechanism, so as to facilitate the disassembly of the voltage transformer body 10. Thus, through the above structure, the installation efficiency and maintenance convenience of the voltage transformer are improved, and the positioning is accurate and the installation is stable.

[0018] Both sets of connecting plates 7 are integrally formed with the mounting base 3 and are respectively placed above the two sets of positioning grooves 6. The integral formation of the two sets of connecting plates 7 with the mounting base 3 and their position above the two sets of positioning grooves 6 can not only enhance the structural strength of the connecting plates 7, but also ensure that the pre-positioned protruding plate 12 can be accurately aligned with the connecting plates 7, thereby improving the installation stability and alignment accuracy.

[0019] The fixing mechanism includes a retaining ball 15. A insertion groove 19 is provided at the bottom of the connecting plate 7. A retaining tube 13, adapted to the insertion groove 19, passes through the protruding plate 12. Two sets of placement grooves 14 are symmetrically provided on the inner wall of the retaining tube 13 near its end, and retaining balls 15 are placed therein. A lead screw 16 is threadedly connected to the inner side of the retaining tube 13. One end of the lead screw 16 has a knob 17, and the other end has a contact head 18 that abuts against the two sets of retaining balls 15. When the fixing mechanism is working, after the pre-positioning mechanism completes the pre-positioning of the connecting seat 11 and the mounting seat 3, the retaining tube 13 on the protruding plate 12 can be precisely aligned with the insertion groove 19 at the bottom of the connecting plate 7. Under the action of the spring 9, the retaining tube 13 can be inserted into the insertion groove 19. Then, rotating the knob 17 at one end of the lead screw 16 can drive the lead screw 16 to move inside the retaining tube 13. The screw rotates and moves toward the end of the plug-in cylinder 13. The contact head 18 at the other end of the screw 16 can move with the screw 16. It can gradually come into contact with and squeeze the two sets of retaining balls 15 in the placement groove 14. Under the action of the contact force, parts of the two sets of retaining balls 15 can pop out from the placement groove 14 and be inserted into the plug-in groove 19, thereby locking the plug-in cylinder 13 and the plug-in groove 19. This can fix the convex plate 12 and the connecting plate 7. When disassembling, turn the knob 17 in the opposite direction, which can drive the screw 16 and the contact head 18 to disengage from the retaining balls 15. After the retaining balls 15 lose the contact force, they return to the placement groove 14, and the plug-in cylinder 13 can be pulled out. This can release the fixation of the convex plate 12 and the connecting plate 7. Thus, by setting it up, the voltage transformer body 10 can be quickly locked and unlocked without additional tools, making disassembly and assembly convenient.

[0020] Among them, the two sets of protruding plates 12 are adapted to the two sets of vertical grooves 4, movable grooves 5, and positioning grooves 6. The two sets of protruding plates 12 are adapted to the two sets of vertical grooves 4, movable grooves 5, and positioning grooves 6. During the pre-positioning process, they can slide along the vertical grooves 4, rotate in the movable grooves 5, and be inserted into the positioning grooves 6 in sync with the connecting seat 11. This can not only help to complete the accurate pre-positioning, but also avoid structural interference between the protruding plates 12 and the mounting seat 3, thus improving the smoothness of installation.

[0021] The fixed base 1 has four corners with fixing holes 2 to facilitate its installation and fixation. The fixing holes 2 at the four corners of the fixed base 1 can be used to quickly fix the fixed base 1 to the outdoor installation position with fasteners such as bolts, providing a stable support for the entire voltage transformer and ensuring that it is not easy to move when used outdoors.

[0022] Working principle: First, align the connecting seat 11 at the bottom of the voltage transformer body 10 with the mounting seat 3 at the top of the fixed base 1 and press it down. This causes the outer ring of the connecting seat 11's protruding plate 12 to slide down along the vertical groove 4 on the side wall of the mounting seat 3 and compress the inner abutment plate 8 and spring 9. After the protruding plate 12 slides to the bottom of the vertical groove 4, rotate the connecting seat 11 so that the protruding plate 12 slides into the movable groove 5 and finally locks into the positioning groove 6. At this time, under the action of the spring 9, the abutment plate 8 is lifted, which can press the connecting seat 11 to complete the pre-positioning. At the same time, the protruding plate 12 is aligned with the connecting plate 7 on the mounting seat 3. The plug-in cylinder 13 on the 2 can be inserted into the plug-in slot 19 of the connecting plate 7. By rotating the knob 17, it can drive the lead screw 16 forward, causing the contact head 18 at its end to press the retaining ball 15 inside the plug-in cylinder 13. The retaining ball 15 can pop out and lock into the plug-in slot 19. When disassembling, rotate the knob 17 in the opposite direction, which will drive the contact head 18 to retract and release the retaining ball 15, so that the plug-in cylinder 13 can be pulled out. Rotating the knob in the opposite direction and lifting the connecting seat 11 can disengage the convex plate 12 from the positioning slot 6, so that the voltage transformer body 10 can be removed, thus completing the entire operation process.
