DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 12 As shown, the present invention provides a quick-release structure of an electric meter box cover, including a box body 1 and a box cover 2, wherein at least two bases 3 are detachably connected at intervals along the height direction near the edge of the front side of the box body 1, and a space-avoiding groove 4 for the front end of the base 3 to be placed is arranged on the box cover 2 corresponding to the position of the base 3, and a connecting column 5 is vertically arranged in the space-avoiding groove 4, the rear side of the base 3 is connected to the box body 1, and a columnar installation groove 6 with a lateral opening for the connecting column 5 to be placed laterally is vertically arranged on the front side of the base 3, and a connecting notch 7 is arranged from the back to the front in the base 3, and the front end of the connecting notch 7 is The upper and lower parts are provided with outwardly extending locking holes 8; a connecting block 9 is inserted into the connecting notch 7, and elastic strips 10 are provided on the upper and lower sides of the connecting block 9, and the front end of the elastic strip 10 extends outward to form a locking block 11, and the front end of the connecting block 9 is vertically provided with an arc-shaped mounting strip 12 with an opening on one side; after the connecting block 9 is inserted into the connecting notch 7 and is in place, the locking block 11 is snapped into the locking hole 8 and buckled to prevent it from falling out, and the arc-shaped mounting strip 12 blocks the lateral opening part of the columnar mounting groove 6 to prevent the connecting column 5 from falling out laterally; the other side of the box cover 2 is correspondingly provided with a locking member connected and fixed to the box body 1.

[0025] Preferably, a base mounting groove 13 is provided at the box body 1, and the base 3 is connected to the screw hole of the base mounting groove 13 by screws.

[0026] Preferably, an observation hole 14 is provided on the base 3 , one end of the observation hole 14 is connected to the locking hole 8 , and the other end of the observation hole 14 passes through the surface of the base 3 .

[0027] Furthermore, an operating panel 15 extends outward from the inner surface of the connecting block 9. When the operating panel 15 is pressed backward with force, the elastic strip 10 is deformed so that the block 11 disengages from the locking hole 8 and moves backward. The arc-shaped mounting strip 12 leaves the lateral opening of the columnar mounting groove 6 so that the connecting column 5 can be laterally disengaged.

[0028] During installation, first insert the connecting block 9 into the connecting notch 7 of the base 3 from the back to the front, then connect the base 3 to the screw hole of the base mounting groove 13 of the box body 1 by screws, then align the air avoidance groove 4 of the box cover 2 with the base 3, and laterally insert the connecting column 5 into the columnar mounting groove 6 of the base 3, press and push the operating plate 15 forward, drive the connecting block 9 to move forward, and the elastic strip 10 deforms so that the block 11 is inserted into the positioning hole 8 and buckled upside down to prevent it from falling out. At this time, the arc-shaped mounting strip 12 blocks the lateral opening part of the columnar mounting groove 6 to prevent the connecting column 5 from falling out laterally, completing the limiting of the connecting column 5 so that the connecting column 5 can only be in a rotating state. After the multiple connecting columns 5 on the box cover 2 are installed, the installation process of the box cover 2 is completed.

[0029] During disassembly, force is applied to the operating panel 15 to move the operating panel 15 backward, so that the elastic strip 10 is deformed so that the block 11 is disengaged from the locking hole 8, and then the arc-shaped mounting strip 12 leaves the lateral opening of the columnar mounting groove 6. At this time, the connecting column 5 can be disengaged laterally. After the multiple connecting columns 5 on the box cover 2 are all disengaged, the disassembly process of the box cover 2 is completed.

[0030] The above installation and disassembly process is convenient and quick, the overall structure is novel, the use is stable and the quality is reliable.

[0031] The above description is only a preferred embodiment of the present invention and does not impose any form of limitation on the invention. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
