Detailed Implementation
[0010] The present invention will now be described in further detail with reference to the accompanying drawings.
[0011] like Figures 1 to 7As shown, the present invention provides an electric shock protection meter box, including a front housing 1 and a rear housing 2. An electric meter 3 is connected to the upper part of the front side of the rear housing 2, and a control switch 4 is connected to the lower part of the front side of the rear housing 2. A transparent cover 5 is connected to the upper part of the front housing 1 corresponding to the position of the electric meter 3. An operation hole 11 is provided on the lower part of the front housing 1 corresponding to the control switch 4. Vertical slots 12 are respectively provided on the left and right outer sides of the operation hole 11 on the rear side of the front housing 1. A [missing information - likely a design feature or feature] is provided on the upper outer side of the vertical slots 12. The limiting block 13 has a sliding cover 6 on the outer side and an insulating protective cover 7 on the inner side inserted from top to bottom in the vertical slot 12. The insulating protective cover 7 has elastic hooks 71 extending from the top left and right sides. After the insulating protective cover 7 is inserted from top to bottom, the elastic hooks 71 deform and buckle upside down on the bottom surface of the limiting block 13 to prevent it from falling out. The insulating protective cover 7 is provided with an operation port 72. The operation flip button part 41 of the control switch 4 protrudes from the operation hole 11. The transparent cover 5 has a flip cover 8 hinged to the outside.
[0012] Specifically, the left and right sides of the rear side of the front housing 1 are vertically provided with positioning ribs 14, the top of the rear side of the front housing 1 extends backward with a rainproof strip 15, the rainproof strip 15 extends to the top of the positioning ribs 14 on the left and right sides, and the horizontal area of the rainproof strip 15 at the top of the front housing 1 extends downward with a locking strip 16; the left and right sides of the front side of the rear housing 2 are vertically provided with locking positioning grooves 21, the top of the front side of the rear housing 2 extends horizontally upward to form a positioning boss 22, when the front housing 1 is fastened to the rear housing 2, the top is fastened to the positioning boss 22 by the locking strip 16, and the left and right sides are engaged into the locking positioning grooves 21 by the positioning ribs 14.
[0013] Specifically, the transparent cover 5 is provided with a groove, and a cover plate 9 is hinged to the top of the groove. A vertical card insertion hole 51 is provided in the groove corresponding to the position of the meter slot, and a reset button hole 52 is provided in the groove corresponding to the position of the meter reset button.
[0014] Specifically, a gripper 61 extends outward from the lower part of the sliding cover 6.
[0015] In this invention, the sliding cover 6 is inserted into the outer area of the vertical slot 12 from top to bottom, and the insulating protective cover 7 is inserted into the inner area of the vertical slot 12 from top to bottom. After the elastic buckle 71 at the top of the insulating protective cover 7 is deformed, it is snapped upside down on the bottom surface of the limiting block 13 to prevent it from falling out. The operation flip button part 41 protruding from the front end of the control switch 4 extends out from the operation port 72 on the insulating protective cover 7. The metal screw connected to the control switch 4 is blocked inside by the insulating protective cover 7 to ensure that the metal screw will not be touched when the switch is turned by hand.
