Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically, to a small transformer that is convenient to disassemble. Background Technique

[0002] Small transformers mainly refer to transformers with a single-phase capacity below 20 KV·A and a three-phase capacity below 50 KV·A. They are characterized by small volume, low cost, and less wire usage. The load factor and utilization rate of small transformers are generally low. The inductive loads they carry are generally not compensated capacitively, and they are widely used in various electrical equipment. Existing small transformers are generally fixed to the carrier by screws, and the disassembly and assembly are relatively cumbersome.

[0003] After retrieval, the utility model patent with the publication number CN218447459U discloses a small transformer that is convenient to disassemble, including a small transformer body and a mounting base. A plurality of connecting plates are respectively fixedly installed on both sides of the small transformer body. One end surface of each connecting plate is fixedly connected with a plug post, and the plug post is movably inserted into a slot. The slots are recessed at the four corners of the mounting base. The mounting base is hollow and provided with a movable cavity. A plurality of locking components are movably arranged in the movable cavity, and an unlocking component is in sliding contact between the locking components; through the cooperation of the plug post and the slot, the disassembly and assembly between the small transformer body and the mounting base are facilitated, avoiding the situation of thread slipping caused by frequent screwing of fixing bolts and ensuring the fastening degree of installation.

[0004] However, the above patent still has the following deficiencies: Locking and unlocking the transformer are achieved by pulling the movable column, but the movable column is placed outside and not protected and fixed, there is a risk of accidental touch causing the fixing of the transformer to be released; and the firmness of fixing the transformer only by the insertion of four plug posts is still somewhat lacking. For this reason, we propose a small transformer that is convenient to disassemble. Content of the Utility Model

[0029] In this embodiment, the side surface of the L-shaped insert block 10 fits against the inner walls of the moving groove 8 and the L-shaped slot 7, ensuring the stability of the L-shaped insert block 10 within the moving groove 8 and the L-shaped slot 7. Additionally, the outer shape and size of the top end of the L-shaped insert block 10 are equal to the size of one end of the inner cavity of the L-shaped slot 7, ensuring the stability of the top end of the L-shaped insert block 10 when inserted into the inner cavity of the L-shaped slot 7.

[0030] Specifically, please refer to Figure 3 , the driving mechanism 15 includes a dual-axis motor 13 fixedly installed in the middle of the inner cavity of the mounting base 1. The two output shafts of the dual-axis motor 13 are respectively fixedly connected to screw rods 14. The end parts of the two screw rods 14 are respectively rotatably connected to the side part of the mounting base 1, and the two screw rods 14 are respectively threadedly sleeved with two moving seats 9.

[0031] Specifically, please refer to Figure 6 , a control box 17 is fixedly connected to the side part of the mounting base 1. A box door 18 is hinged to the outside of the control box 17, and a controller 19 is fixedly installed on the inner wall of the control box 17.

[0032] In this embodiment, the controller 19 is used to control the dual-axis motor 13.

[0035] Specifically, please refer to Figure 2 , two lifting rings 22 are fixedly connected to the top surface of the small transformer body 2.

[0036] In this embodiment, the small transformer body 2 is lifted using the lifting rings 22.

[0037] Specifically, please refer to Figures 1 to 3 , the outer diameter of the plugging post 5 is equal to the inner diameter of the jack 3, the outer diameter of the annular groove 6 is equal to the inner diameter of the arc-shaped clamping groove 12, and the top surface and the bottom surface of the clamping seat 11 respectively fit against the top surface and the bottom surface of the inner cavity of the annular groove 6.

[0038] In this embodiment, the stability of fixing the plugging post 5 is ensured through the cooperation of the arc-shaped clamping groove 12 and the annular groove 6.

[0039] Specifically, please refer to Figure 1 and Figure 3 , the top surface and the bottom surface of the moving seat 9 respectively fit against the top surface and the bottom surface of the mounting base 1.

[0041] Working principle: When in use, first, the mounting base 1 is fixed through the cooperation of the mounting plate 20, the mounting hole 21 and the bolts, and the small transformer body 2 is lifted to the top of the mounting base 1 by using the lifting ring 22, so that the plug column 5 at the bottom of the small transformer body 2 is inserted into the inner cavity of the jack 3, and at the same time the top end of the L-shaped plug 10 is inserted into the inner cavity of the L-shaped slot 7. Then, the double-shaft motor 13 is started to drive the two screw rods 14, and the two moving bases 9 are driven to move away from each other through the threaded cooperation between the screw rods 14 and the moving bases 9, so that the arc-shaped slots 12 on the side clamping seats 11 of the moving bases 9 are inserted into the outside of the annular groove 6, and the plug column 5 is fixed by the clamping seats 11. In addition, when the moving base 9 moves, the L-shaped plug 10 is driven to move, so that the end of the L-shaped plug 10 is inserted into the side of the L-shaped slot 7, thereby installing the small transformer body 2 on the mounting base 1. Then, when it is necessary to disassemble the small transformer body 2, the double-shaft motor 13 is started to drive the two screw rods 14 to reverse, and the two moving bases 9 are driven to move closer to each other through the threaded cooperation between the screw rods 14 and the moving bases 9. At the same time, the arc-shaped slots 12 on the clamping seats 11 are separated from the outside of the annular groove 6, and at the same time, one end of the L-shaped plug 10 is separated from the inner cavity of the L-shaped slot 7, thereby releasing the fixation between the mounting base 1 and the small transformer body 2. Finally, the small transformer body 2 is lifted from the mounting base 1 again by using the lifting ring 22, and that's it.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
