Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 6, an easily assembled signaling water meter includes a housing 1 and a base meter, the base meter includes a case 2, a glass 3, and a middle cover 4 disposed on the glass 3 and pressing the glass 3, an annular gasket 5 is disposed between the middle cover 4 and the glass 3, the annular gasket 5 includes an annular body 51 and an annular positioning body 52 coaxially disposed, the annular body 51 is fixedly disposed between the middle cover 4 and the glass 3, the annular positioning body 52 is disposed in an inner ring of the middle cover 4, a certain gap 6 is disposed between the annular positioning body 52 and the glass 3, a notch 521 is disposed on an inner peripheral wall of the annular positioning body 52, a hook 11 is disposed on the housing 1, when the housing 1 is covered on the base meter from top to bottom, the hook 11 passes through the notch 521, and after the housing 1 rotates by a certain angle, the hook 11 rotates along the gap 6 and abuts against the annular positioning body 52, the rotary assembly of the shell 1 and the base meter is completed, screws are not needed, the assembly procedures are reduced, the assembly time is greatly reduced, and the assembly of the water meter is simpler and more convenient.
The number of the hooks 11 and the notches 521 may be one, or a plurality of hooks 11, and the number of the hooks 11 may be equal to or less than the number of the notches 521.
In this embodiment, the outer diameter of the annular body 51 is larger than the outer diameter of the annular positioning body 52, and the annular positioning body 52 is in an inverted L shape.
The inner peripheral wall of the annular positioning body 52 is further provided with limiting teeth 522, the shell 1 is further provided with a slot 12, and after the shell 1 rotates for a certain angle, a limiting block 7 is inserted into the slot 12 and meshed with the limiting teeth 522. The rotation of the case 1 assembled on the base watch can be prevented by the cooperation of the limit block 7 and the limit teeth 522.
In order to improve the horizontal positioning between the housing 1 and the base watch, the limiting block 7 is provided with engaging teeth 71, and the engaging teeth 71 are matched with the limiting teeth 522. After the limiting block 7 is inserted into the slot 12, the engaging teeth 71 engage with the limiting teeth 522, and the limiting teeth 522 are arranged on the inner peripheral wall of the annular positioning body 52, so that the strength of the limiting teeth arranged on the outer peripheral wall of the annular positioning body is higher than that of the limiting teeth, and the shell 1 is less prone to rotating.
The limit teeth 522 may be provided as a segment, or may be provided around the inner peripheral wall of the annular positioning body, preferably the latter.
In order to fix the limiting block 7 and the shell 1, a positioning table 13 is arranged in the slot 12, a positioning hole 131 is arranged on the positioning table 13, a limiting hole 72 is formed in the limiting block 7, a positioning pin is inserted into the limiting hole 72 and the positioning hole 131, or an elastic point 73 is arranged on the side face of the limiting block 7, and when the limiting block 7 is inserted into the slot 12, the elastic point 73 is elastically abutted against the side wall of the slot 12. The latter arrangement mode is adopted in the embodiment, and after the limiting block 7 of the latter is inserted, the elastic point 73 is elastically abutted to the side wall of the slot 12, so that the limiting block 7 is not easy to be taken out, and the two modes can be combined for use.
Firstly, covering the annular gasket 5 on the glass 3, then rotationally fastening the middle cover 4 and the watch case 2, at this time, the annular body 51 can be partially or completely firmly pressed between the middle cover 4 and the glass 3, the annular positioning body 52 is completely positioned in the inner ring of the middle cover 4, then covering the annular body 1, inserting the hook 11 on the casing 1 into the notch 521, then rotating the casing 1, rotating the hook 11 along the gap 6, after rotating a certain angle, assembling the casing 1 and the base watch in place, abutting the hook 11 and the annular positioning body 52 up and down, enabling the base watch and the casing 1 to realize the up-and-down fixation, then inserting the limiting block 7 into the slot 12, elastically abutting the elastic point 73 on the limiting block 7 with the side wall of the slot 12, and enabling the occlusion tooth 71 to be engaged with the limiting tooth, so that the casing 1 and the base watch do not rotate, and making lead seal on the slot 12, thereby forming an integral water meter 522.
Compared with the water meter in the prior art, the water meter does not need fixing elements such as screws and bolts, reduces the assembly procedures and the assembly time, can form a complete water meter only by carrying out lead sealing on the shell, and does not need to carry out lead sealing on the base meter and the shell respectively.
