Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

Referring to fig. 1-3, a power supply with a waterproof structure comprises an outer casing 1, outer vent holes 2 are formed on the left and right sides of the outer casing 1, a dust screen is arranged inside the outer vent holes 2 to prevent dust from entering the inner part, an inner casing 3 is arranged inside the outer casing 1, a backing plate 17 is arranged at the bottom of the inner casing 3 for supporting, a power supply body 4 is arranged inside the inner casing 3, a power output line and a power input line are connected to the bottom of the power supply body 4, inner vent holes 5 are formed on the left and right sides of the inner casing 3, expansion devices are arranged on the left and right sides of the inner part of the outer casing 1, the two expansion devices are symmetrically arranged, a push plate 6 is fixedly connected to the front end of each expansion device, each expansion device is an expansion link 10 with a spring inside, a limiting device for limiting the expansion link 10 is further arranged on the outer casing 1, each limiting device comprises a lifting plate 11, limiting blocks 12 are arranged on the two sides below the lifting plate 11, two sides above the lifting plate 11 are provided with slide bars 13, the slide bars 13 pass through the top of the outer shell 1 and are connected with a handle 14, the push plate 6 is provided with a plurality of waterproof plugs 7, the positions of the waterproof plugs 7 correspond to the positions of the inner vent holes 5 on the inner shell 3, the waterproof plugs 7 are provided with expansion parts 9, the expansion parts 9 are made of elastic materials, in the embodiment, silica gel is adopted as the material for forming the expansion parts 9, the diameter of the middle of the expansion parts 9 is larger than the diameter of two sides, after the waterproof plugs 7 enter the outer vent holes 2, the inner cavity of the outer vent hole 2 can extrude the expansion part 9, so that the waterproof effect of the waterproof plug 7 is better, under the normal state, the push plate 6 at the front end of the telescopic rod 10 is in a compressed state under the action of the limiting block 12, the waterproof plug 7 is far away from the outer vent hole 2, so that the power supply body 4 keeps a ventilation and heat dissipation state, and the bottom of the outer shell 1 is also provided with a water level sensor 8.
