Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 9, the invention provides a quick-release structure for a box cover of an electric meter box, which comprises a box body 1 and a box cover 2, wherein at least two bases 3 are arranged on one side of the front surface of the box body 1 at intervals along the height direction near the edge, a shaft hole 4 and an arc-shaped avoiding groove 5 are vertically arranged on each base 3, a base mounting part 6 is arranged on the inner side surface of the box cover 2 corresponding to the position of each base 3, an upper limiting block 7 and a lower limiting block 8 are arranged on each base mounting part 6, shaft holes are vertically arranged on the upper limiting block 7 and the lower limiting block 8, the base 3 is positioned between the upper limiting block 7 and the lower limiting block 8, and a clamping block 9 extends out of the side surface of the upper limiting block 7; the clamping device is characterized by further comprising a pin shaft 10, wherein the top end of the pin shaft 10 is connected with a clamping sleeve 11, an elastic clamping hook 12 extends out of the outer side of the clamping sleeve 11, and the pin shaft 10 penetrates through shaft holes of the upper limiting block 7, the base 3 and the lower limiting block 8 respectively and then the elastic clamping hook 12 at the top of the pin shaft is deformed and clamped in the clamping block 9 for fixing in a reverse clamping manner; the other side of the box cover 2 is correspondingly provided with a clamping locking piece fixedly connected with the box body 1.
On the basis of the above scheme, preferably, the side surface of the box cover 2 is provided with a clearance groove 13 at a position between the upper limiting block 7 and the lower limiting block 8, and the position of the clearance groove 13 corresponds to the arc-shaped clearance groove 5. And, the arc dodges the crooked radian direction of groove 5 and case lid 2 and opens the rotation direction looks adaptation of in-process dodging slot 13 for can not produce the interference in base 3 department when case lid 2 is opened, the case lid 2 of being convenient for is normally opened.
Preferably, a base mounting groove 14 is formed at the box body 1, and the base 3 is connected in a screw hole of the base mounting groove 14 by a screw.
In the above scheme, one case body 1 may be correspondingly matched with one case cover 2, or may be matched with two case covers 2, or even multiple case covers 2, which may be designed and changed by a designer according to needs.
In addition, the base 3 can also be one and is arranged at the middle position of the edge of the box body 1, and theoretically, the function can also be realized.
The core point of the invention is that on the basis of realizing the hinge function, the connecting structure between the box cover 2 and the box body 1 can carry out the manual quick assembling and disassembling function, and the assembling and disassembling process does not need to use external tools.
When dismantling case lid 2, only need open case lid 2, pull elasticity trip 12 outward with the hand for elasticity trip 12 breaks away from out fixture block 9 lower surface, upwards extracts cutting ferrule 11, because cutting ferrule 11 and round pin axle 10 link into an organic whole, and round pin axle 10 follows cutting ferrule 11 and extracts, and the spacing fixed mode between base installation department 6 on case lid 2 and the base 3 this moment just is in the relieved state, extracts all cutting ferrule 11 the back, can directly take off case lid 2, realizes dismantling. Similarly, when the box cover 2 is installed, the box cover 2 is well aligned, the clamping sleeve 11 and the pin shaft 10 are inserted from top to bottom, and the elastic clamping hook 12 is deformed and reversely clamped after being inserted in place, so that the installation of the box cover 2 can be completed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change or modification made to the above embodiments according to the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
