Detailed Description

The technical solutions of the present invention will be explained and explained in detail with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement the present invention.

Example 1

Referring to fig. 1 and fig. 6, the polymer is a gas meter and includes an upper cover 1 and a bottom case 2, the upper cover 1 and the bottom case 2 are fastened by two sets of fasteners a and B, and are fixed by screws in combination with two screw holes C.

Referring to fig. 2 and 3, the fastener a includes a first slot 11 and a second projection 12 configured on the top side of the upper cover 1 and configured in parallel and adjacent to each other, and a third projection 13 configured in the direction perpendicular to the second projection 12; the bottom case 2 is configured with a first protrusion 21 at a position corresponding to the first locking groove 11 of the upper cover 1, a second locking groove 22 at a position corresponding to the second protrusion, and a third locking groove 23 at a position corresponding to the third protrusion. In addition, one side surface of the third bump 13 of the upper cover 1 close to the second bump 12 is an inclined surface, so that the third bump 13 can be conveniently slid into the third slot 23 during buckling, and is not easy to be separated after being slid into the third slot, thereby playing a fastening role.

Referring to fig. 4 and 5, the buckle B includes a fourth protrusion 14 and a fifth locking groove 15 respectively configured at two side edges of the upper cover 1 from inside to outside, and a sixth locking groove 16 configured in a direction perpendicular to the fifth locking groove 15; the two side edges of the bottom case 2 are configured with a fourth locking groove 24 corresponding to the fourth protrusion 14 of the upper cover 1, a fifth protrusion 25 corresponding to the fifth locking groove 15 of the upper cover 1, and a sixth protrusion 26 corresponding to the sixth locking groove 16 of the upper cover 1. Similarly, a side surface of the sixth protrusion 26 close to the fifth protrusion 25 is an inclined surface, so that the sixth protrusion 26 can slide into the sixth slot 16 when being fastened, and is not easy to be separated after sliding, thereby playing a fastening role.

The upper cover 1 and the bottom shell 2 are also respectively provided with two corresponding screw holes C at the lower part for screwing and fixing, see 6.

When the polymer is connected and fixed, the convex blocks and the clamping grooves of the buckle A and the buckle B are aligned and slide into the clamping groove, and then the screw is screwed into the two screw holes C, so that the operation is simple and convenient.
