Description of the drawings
Fig. 1 is the power supply waterproof case dimensional structure diagram of the utility model embodiment；
Fig. 2~Fig. 3 is the close-up schematic view of Fig. 1.
Specific implementation mode
As shown, a kind of power supply waterproof case, including upper cover 1, lower cover 4, upper cover 1, lower cover 4 are all the box of one side opening
Body, upper cover 1, lower cover 4, which work in coordination to combine, constitutes outer casing of power supply, and the box opening face edge of lower cover 4 is provided with from cooperation
Raised limit ribs upwardly, limit ribs lateral surface are adapted with 1 medial surface shape of upper cover, size；On the outside of limit ribs
It is provided with the limiting slot 7 for coordinating certainly and being recessed downwards, 7 medial surface of limiting slot and limit ribs lateral surface are in the same plane,
Water proof ring 2 is installed, upper cover 1 squeezes water proof ring 2 simultaneously when being assembled with the cooperation of lower cover 4 so that water proof ring 2 seals in limiting slot 7
Between upper cover 1 and lower cover 4, waterproof, insect prevention, corrosion resistance and good, degree of protection height；Upper cover 1 is provided at both ends with outwardly convex
Clamp boss 12, the middle part of clamp boss 12 has groove, the limit ribs at 4 both ends of lower cover corresponding to the groove of clamp boss 12
Position setting is jagged, and 4 box body of lower cover is located at the side wall outside notch and is provided with what outwardly directed and clamp boss 12 was adapted
Block 8；4 box body quadrangle of lower cover is provided with through-hole 3 up and down, and 1 box body quadrangle of upper cover is provided with spiral shell with 3 corresponding position of through-hole
Line counterbore, limit ribs quadrangle are arc transition, and arc transition section is recessed inwardly, and through-hole 3 and arc transition section are concentric；Upper cover 1
Mating surface edge surrounding have outwardly convex reinforcing rib 6,4 mating surface edge surrounding of lower cover also have corresponding reinforcing rib,
To enhance outer casing of power supply bonding strength；1 medial surface of upper cover is with after the limit ribs cooperation assembly of lower cover 4, and from 4 bottom of lower cover, warp is logical
Hole 3 penetrates screw 10 and is fastenedly connected with the screw-threaded counterbore of upper cover 1, and connection is reliable, easy to operate.
2 height of water proof ring is more than the 3/2 of 7 depth of limiting slot, and water resistance can be effectively ensured.
