In the figure: the water inlet pipe comprises a lower shell 101, a concave sliding groove 102, a through hole 103, a limiting groove 104, an upper shell 201, a convex sliding block 202, a display screen 203, a limiting plate 204, a card slot 205, a metal shell 301, a counting cover 302, a water inlet pipe 303, a water outlet pipe 304 and a torsion spring 4.

Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

As shown in fig. 1-6, a water meter shell, includes metal casing 301, goes up casing 201 and casing 101 down, count cover 302 is installed to metal casing 301 upper end, and inlet tube 303 and outlet pipe 304 are installed respectively to the lower extreme both sides, be equipped with through-hole 103 and concave spout 102 on the casing 101 down, it is equipped with limiting plate 204 and protruding slider 202 to go up casing 201, through-hole 103 with metal casing 301 cooperation, it is located directly over lower casing 101 to go up casing 201, it passes through to go up casing 201 limiting plate 204 with count cover 302 cooperation, protruding slider 202 with concave spout 102 cooperation, limiting plate 204 with torsional spring 4 still installs between the protruding slider 202.

A gap is formed between the limiting plate 204 and the bottom end of the counting cover 302.

The upper end of the torsion spring 4 is connected with the limiting plate 204, and the lower end of the torsion spring 4 is connected with the counting cover 302.

The lower end of the lower shell 101 is also provided with a limiting groove 104, and the limiting groove 104 is matched with the water outlet pipe 304 to ensure that the lower shell 101 is not rotated when being matched with the metal shell 301.

The upper end of the upper shell 201 is also provided with a display screen 203.

The side end of the upper shell 201 is also provided with a card slot 205.

The upper shell 201 and the lower shell 101 are made of plastic.

The specific working process is as follows: when the installation position of the water meter is narrow and card-inserting recharging can not be carried out, a user only needs to pull the upper shell by hand, the upper shell can rotate around the counting cover under the action of the limiting plate as shown in fig. 6, the torsion spring is compressed in the rotating process, and the position of the card-inserting groove in the upper shell is changed to an open position along with the rotation of the upper shell, so that the user can conveniently carry out card-inserting recharging, and the user can conveniently read the current use condition of the water meter through the display screen; after recharging is completed, the upper shell is only required to be loosened, the upper shell is driven to automatically reset under the action of the reset elastic force of the torsion spring, and meanwhile, the upper convex sliding block of the upper shell is matched with the upper concave sliding groove of the lower shell, so that the upper shell and the lower shell are in a parallel state under the condition of no relative rotation.
