[0018] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0019] Embodiment

[0020] As Figs. 1-2 shown, a fan plug body skin anti-deformation structure, including fan panel 1, one side of fan panel 1 is connected with skin 3, the lower end of skin 3 is respectively provided with baffle 2, top plate 5 and multiple supporting plates 4, and top plate 5 is located between multiple supporting plates 4.

[0021] Strip groove 6 is formed in skin 3, and the width of strip groove 6 is less than or equal to 5 mm, when plug body skin 3 expands and contracts, a certain expansion space and expansion amount are realized through strip groove 6, and the phenomenon of deformation due to expansion and contraction is prevented.

[0022] One end of skin 3 is connected with fan panel 1, the lower end of skin 3 is welded with baffle 2, the lower end of baffle 2 is connected with supporting plate 4, the upper end of baffle 2 is broken welded with skin 3, the broken welding structure is adopted between one side of skin 3 and baffle 2, a live lap joint mode is formed, a certain amount of expansion space is provided in plug body expansion and contraction through strip groove 6, and the welding seam is divided into several segments by adopting the broken welding method, so that the risk of welding deformation and cracking is reduced.

[0023] Multiple supporting plates 4 are two in number and are respectively arranged on both sides of top plate 5, the upper end of supporting plate 4 is connected with baffle 2, and two supporting plates 4 sandwich top plate 5 to support.

[0024] The top plate 5, the support plate 4 and the baffle 2 are perpendicular to each other, the upper end of the top plate 5 and the baffle 2 have an expansion gap 7, the length of the expansion gap 7 is less than or equal to 10 mm, when the top plate 5 is expanded or contracted, a certain amount of vertical expansion space is provided through the expansion gap 7 at the upper end, so that transverse deformation is prevented.
