Abstract
The invention discloses a waterproof structure of an outer shell of an intelligent gas meter. The waterproof structure comprises a front shell and a rear shell which are matched in a covered mode, the splicing parts of the front shell and the rear shell are provided with a concave groove and a convex groove matched with the concave groove, the outer side wall of a concave opening of the concave groove is connected with the side wall of a convex opening of the convex groove in an abutting-against mode, a drain opening is formed in the outer side wall at the bottom of the concave groove, and a drain groove is formed in the bottom of the concave opening of the concave groove. By applying the waterproof structure, the matched concave groove and convex groove waterproof structure is arranged on the outer shell, additional waterproof units including waterproof strips and the like are not needed, and the waterproof structure is simple in structure, high in waterproof performance, long in waterproof effective life and low in cost; the drain groove and the drain opening are additionally formed and can guide and drain water immerging in a shell body, stop the water from immerging into the shell body and protect the gas meter.
Description
Technical field
The present invention relates to a kind of proof mechanism of water, relate in particular to a kind of waterproof construction of intelligent gas watch case.
Background technology
A lot of resident families all can use gas meter, flow meter, and gas meter, flow meter, for to using combustion gas to measure, has circuit and electronic devices and components etc. in gas meter, flow meter, and when gas meter, flow meter is intake, water body can damage circuit and electronic devices and components, cause gas meter, flow meter to damage.
In prior art, relate to a kind of intelligent gas meter, in this intelligent gas meter, also there is communication facilities etc., thus to the having relatively high expectations of water proofing property, and existing waterproof construction to be housing increase the waterproof constructions such as water-proof strip, this kind of waterproof construction is mainly the effect that water body is stopped, when the water yield is excessive or service time is longer, water body still can immerse in gas meter, flow meter, and gas meter, flow meter is damaged, and additional waterproof construction, has improved assembly cost.
Summary of the invention
The object of the invention is to the technical matters solving, propose a kind of waterproof construction of intelligent gas watch case.
Object of the present invention, will be achieved by the following technical programs:
The waterproof construction of intelligent gas watch case, comprise the fore shell and the back cover that cover mutually, especially, the splicing position of described fore shell and back cover is provided with groove and the tongue matching, the recess lateral wall of described groove and the tang sidewall of tongue connect, the groove lateral wall of described bottom portion of groove is provided with drain port, and the notched bottoms of described groove is provided with drain tank.
Preferably, the cross section of described drain tank is that trapezoidal, trapezoidal wedge angle position is runner.
Beneficial effect of the present invention is mainly reflected in:
1. the groove matching is set on shell and tells groove waterproof construction, without increasing the additional waterproof unit such as water-proof strip, simple in structure, water resistance is strong, and waterproof useful life is long, and cost is lower;
2. increase drain tank and drain port, can carry out water conservancy diversion discharge to immersing the water body of housing, hindered water body and immersed enclosure interior, protected gas meter, flow meter.
Accompanying drawing explanation
Fig. 1 is the structural representation of intelligent gas meter inner casing of the present invention and shell.
Fig. 2 is the structural representation of the waterproof construction of intelligent gas watch case of the present invention.
Embodiment
The invention provides a kind of waterproof construction of intelligent gas watch case, on shell, increased easy waterproof construction, can intelligent gas meter be caused damage effectively anti-water-stop body.
As depicted in figs. 1 and 2, the waterproof construction of intelligent gas watch case, comprises the fore shell 1 and the back cover 2 that cover mutually, and the splicing position of fore shell 1 and back cover 2 is provided with groove 3 and the tongue 4 matching, and the recess lateral wall 31 of groove 3 connects with the tang sidewall 41 of tongue 4.Concrete, because the groove 3 between housing splices mutually with tongue 4, causing thering is good sealing in housing, internal pressure is almost constant, and when extraneous water body invasion, water body pressurized is difficult to intrude into enclosure interior.4 notched bottoms of groove are provided with drain tank 6, and the recess lateral wall 31 of groove 4 bottoms is provided with drain port 5, and after extraneous water body invasion, water body can enter drain tank, flow to drain port discharge along drain tank, can not intrude into intelligent gas meter inside.For convenience of producing, the cross section of drain tank can be for trapezoidal, trapezoidal wedge angle is partly runner, after housing is invaded by water body, water body can enter in the notch of groove along the groove of case top and the gap of tongue, and trapezoidal wedge angle can hold water body and carry out water conservancy diversion, the drain tank by housing both sides flows down, because the existence of this polymorphic structure can well be discharged from water body.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection scope of the present invention.
Claims (2)
1. the waterproof construction of intelligent gas watch case, comprise the fore shell and the back cover that cover mutually, it is characterized in that: the splicing position of described fore shell and back cover is provided with groove and the tongue matching, the recess lateral wall of described groove and the tang sidewall of tongue connect, the groove lateral wall of described bottom portion of groove is provided with drain port, and the notched bottoms of described groove is provided with drain tank.
2. the waterproof construction of intelligent gas watch case according to claim 1, is characterized in that: the cross section of described drain tank is that trapezoidal, trapezoidal wedge angle position is runner.
