[0013] In summary, the beneficial effects of the present invention are:

[0014] 1. This structure can enhance the structural stability of the switching power supply housing, and support the edges of the switching power supply housing to prevent the corners of the switching power supply from being easily bumped and squeezed and deformed.

[0015] 2. The design of the reinforcement plate and the buckle strip allows people to directly push the reinforcement plate to buckle the buckle strip to the vent, or pinch the buckle strip so that the buckle strip can slide away from the vent to complete the removal and installation of the reinforcement plate. The operation process is relatively convenient.

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 5 As shown, the utility model discloses a reinforced switching power supply, including a housing 1, a plurality of vents 12 are provided on the side wall of the housing 1, and a plurality of reinforcement mechanisms are provided on the housing 1, the reinforcement mechanisms are mainly used to support the inner side wall of the housing 1 with the vents 12, specifically:

[0027] Each group of reinforcement mechanisms includes a plurality of reinforcement plates 21, which are arranged with gaps between and fixedly connected to each other, and each reinforcement plate 21 includes adjacent first side walls 22 and second side walls 23. In this structure, the first side walls 22 and the second side walls 23 are perpendicular to each other, and the first side walls 22 and the second side walls 23 are respectively used to abut against the inner side walls of the shell 1. In addition, the side walls of the reinforcement plates 21 facing the vents 12 are provided with snap-fit ​​portions for detachably connecting the reinforcement plates 21 to the shell 1.

[0028] The buckle portion specifically includes a buckle strip 31, which includes a first rod portion 32 and a second rod portion 33. The first rod portion 32 and the second rod portion 33 are formed by bending the buckle strip 31, and there is an acute angle between the first rod portion 32 and the second rod portion 33, wherein the first rod portion 32 extends into the shell 1 through the vent 12 and is fixedly connected to the reinforcement plate 21, and the second rod portion 33 extends from one end of the first rod portion 32 away from the reinforcement plate 21 and is bent to the outside of the shell 1. In this structure, the end of the second rod portion 33 away from the first rod portion 32 is used to abut against the outer wall of the shell 1.

[0029] At the same time, each buckle portion includes buckle strips 31 in groups of two. In this structure, the first rod portion 32 of each group of buckle strips 31 is used to abut against the two ends of the inner wall of the ventilation opening 12.

[0030] The position of the buckle strip 31 can be further referred to in the accompanying drawings. Figure 1 As shown in the figure, in this embodiment, the housing 1 is provided with ventilation openings 12 on its left side wall and upper side wall. Then, the buckle strips 31 on the left reinforcing plate 21 and the right reinforcing plate 21 are arranged at different positions. Figure 4 As shown, if the upper end face or the left end face of each reinforcing plate 21 in the fixing mechanism corresponds to the ventilation hole, two buckle strips 31 should be provided on the end face of the ventilation hole 12 corresponding to the reinforcing plate 21 for being inserted into the ventilation hole 12. Figure 5 As shown, two buckle strips 31 should be provided on the upper end surface of the reinforcement plate 21 for being inserted into the ventilation opening 12 .

[0031] Through this structure, people only need to align the buckle strip 31 on the reinforcement plate 21 with the vent 12, press the reinforcement plate 21 to the inner wall of the shell 1, and make the buckle strip 31 pass through the shell 1 from the vent 12, so that the buckle strip 31 can be buckled on the shell 1, and thereby achieve the function of fixing the reinforcement plate 21. At the same time, in this structure, since the reinforcement plates 21 are grouped together, the reinforcement plates 21 can be further prevented from being skewed.
