[0033] Based on this, the present application provides a transformer structure, which solves the problem of unstable transformer structure, ensures that the transformer structure is not easily deformed, extends the service life of the transformer body 150, and reduces costs.

[0034] The following references Figure 1 and Figure 3 describe the transformer structure of the embodiments of the present application.

[0035] It can be understood that: The transformer structure of the embodiment of the present application includes: a fixing component, a transformer body 150, and a vertical fixing bracket 170. The fixing component includes a fastener 190 and a fastening adapter 100; The transformer body is provided with a through cavity 151, the through cavity 151 penetrates through the transformer body 150, a structural adhesive is filled in the through cavity 151, and a fixing through groove penetrating the structural adhesive is provided in the structural adhesive; The vertical fixing bracket 170 includes a bottom plate 173 and a side plate 172. The bottom plate 173 and the side plate 172 are perpendicular to each other, the bottom plate 173 is parallel to the horizontal plane, the bottom of the transformer body 150 is connected to the bottom plate 173, the side plate 172 is provided with a first convex portion 171, the first convex portion 171 is engaged with the through cavity 151, the first convex portion 171 is provided with a first fixing hole, the fixing through groove and the first fixing hole are coaxially arranged, one end of the fastener 190 sequentially passes through the first fixing hole and the fixing through groove, the fastening adapter 100 is detachably installed at the other end of the fastener 190, and the fastening adapter 100 abuts against the structural adhesive.

[0036] The beneficial effects of the transformer structure of the embodiment of the present application can be manifested as follows: By installing the transformer body 150 on the side plate 172 of the vertical fixing bracket 170, the vertical installation of the transformer body 150 can be realized, so that the transformer body 150 can adapt to more application scenarios. By connecting the transformer body 150 to the bottom plate 173, it can effectively prevent the transformer body 150 from accidentally detaching and causing excessive damage. By filling the through cavity 151 of the transformer body 150 with structural adhesive, the structural adhesive can fill the inside of the transformer body 150, so that the structure of the transformer body 150 is more stable, less likely to deform during installation, and at the same time, the risk of mechanical failure during use is reduced.

[0037] Exemplarily, in some embodiments, refer to Figure 1 and Figure 3, the fastener 190 and the fastening adapter 100 are a bolt and a nut respectively. A through cavity 151 penetrating the transformer body 150 is provided at the central position of the transformer body 150. The through cavity 151 is filled with structural adhesive, so that the structural adhesive cures in the through cavity 151, and then the transformer body 150 is reinforced and stabilized in the through cavity 151. A fixing through groove is provided on the structural adhesive, and the fixing through groove penetrates the cured structural adhesive. The vertical fixing bracket 170 includes a bottom plate 173 and a side plate 172. The bottom plate 173 and the side plate 172 are perpendicular to each other. The bottom plate 173 is parallel to the horizontal plane. The bottom plate 173 and the side plate 172 are of an integral structure. Triangular reinforcing structures are provided at both ends of the connection between the bottom plate 173 and the side plate 172 to reinforce the connection between the bottom plate 173 and the side plate 172 and prevent deformation. A first convex portion 171 is provided on the side plate 172. The first convex portion 171 can just be engaged with the fixing through cavity 151, and the top surface of the first convex portion 171 abuts against the structural adhesive, thereby ensuring the airtightness of the transformer body 150. A first fixing hole is provided on the first convex portion 171. The fixing through groove and the first fixing hole are coaxially arranged. One end of the bolt sequentially passes through the first fixing hole and the fixing through groove, and the nut is detachably installed at the other end of the bolt, thereby fixing the transformer body 150 and the vertical fixing bracket 170. In the prior art, the vertical transformer body 150 is vertically fixed by suspending it with two groups of brackets. In the embodiment of the present application, the transformer body 150 is connected to the bottom plate 173 instead of being in a suspended state, which can avoid excessive damage caused by the height difference when the transformer body 150 accidentally falls off. And the transformer body 150 is vertically fixed only by one group of vertical fixing brackets 170, so the cost required for the vertical transformer is reduced. The surface of the nut close to the transformer body 150 abuts against the structural adhesive.

Therefore, the sealing of the transformer structure in the embodiments of the present application is jointly achieved by the cover plate 130 and the side plate 172. Therefore, the replacement of the structural adhesive in the transformer structure of the embodiments of the present application is also more convenient. While disassembling the cover plate 130 and the side plate 172, the sealing state of the transformer body 150 can be changed, so that the structural adhesive can be replaced.
