Description

A kind of water meter cover

Technical field

This utility model belongs to field of mechanical technique, relates to a kind of water meter, particularly a kind of Water meter cover.

Background technology

Water meter is the instrument for measuring discharge, would generally be according to actual need during use , periodically or non-periodically copy reading meter reading, therefore, the protective clear layer on water meter rises To being easy to reading and the effect of protective meter dish, but, if not on protective clear layer Installing water meter cover additional, the outer surface of protective clear layer can accumulate substantial amounts of dust, is not easy to reading, And the water meter of outdoor installation is easily intake, the metallic element of inside is caused to get rusty, and then The induction sensitivity causing water meter reduces, and reading is forbidden, additionally, protective clear layer is the easiest Broken by extraneous weight, cause water meter to damage.But, existing structure of water meter cover is complicated, Need during installation to take water meter apart, cause installation inconvenience, and the course of processing of water meter cover Complexity, is generally not capable of one-shot forming, and production cost is high.

The easy mount type plastic water meter lid of one as disclosed in Chinese patent literature (application number: 201510700112.2), include cage, upper cover, between cage, upper cover, be provided with connection Portion, cage is ring-type, and cage is provided with through hole, above covers and is provided with the card matched with through hole Post, card column includes cylinder and is arranged on the convex ball of cylindrical end；In the bottom of cage Edge is provided with at least two holding section, and holding section is on same circumference, the horizontal stroke of holding section Cross sectional shape is the arc that the lower inner edge with cage is agreed with mutually；Outside the lower end of holding section Side is provided with card ear, and Ka Er and holding section are formed barb-like.But the upper cover of this water meter cover is in Free state, therefore its folding more has some setbacks.

Summary of the invention

The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that A kind of smooth opening and closing and water meter cover easy to connect.

The purpose of this utility model can be realized by following technical proposal: a kind of water meter cover, Including downward opening housing, the upper center of described housing has the through hole run through, It is characterized in that, the outside of described housing is uniformly provided with some bar shaped convex bodys and described Bar shaped convex body is parallel to the axis of described housing and arranges, and one of them described bar shaped is convex The upper center of body is provided with the connecting hole run through, and has the described bar shaped convex body of connecting hole Lateral wall be provided with convex shoulder, the sidepiece of described convex shoulder is arcwall face.

The through hole of housing is hinged with lid, and lid is hinged on bar shaped convex body by connecting hole On, owing to the lateral wall of bar shaped convex body is provided with convex shoulder, the sidepiece of convex shoulder is arcwall face, makes During the rotation of lid, there is preferable guidance quality, there is smooth opening and closing and use the most square Just advantage.

In above-mentioned a kind of water meter cover, the two side of described bar shaped convex body is respectively provided with Convex shoulder and two described convex shoulders are symmetrical arranged.It is arranged with on the two side of bar shaped convex body Convex shoulder, has the advantage that structure is relatively stable.

In above-mentioned a kind of water meter cover, the lateral wall of described housing is provided with annular convex shoulder, Described annular convex shoulder is positioned at the middle part of described housing.By arranging annular convex shoulder, just In the crawl of housing, have and dismount conveniently advantage.

In above-mentioned a kind of water meter cover, the quantity of described bar shaped convex body is 3 to 6 And be uniformly distributed centered by the axis of described housing.By above-mentioned setting, make this water The advantage that the intensity of table cover is higher and profile is the most attractive in appearance.

In above-mentioned a kind of water meter cover, described through hole is the taper hole opened toward outside, The tapering of described through hole is 15 °-20 °.

In above-mentioned a kind of water meter cover, the rectangular in cross-section of described bar shaped convex body.

Compared with prior art, this one water meter cover has the advantage that

1, being provided with convex shoulder due to the lateral wall of bar shaped convex body, the sidepiece of convex shoulder is arcwall face, When making the rotation of lid, there is preferable guidance quality, there is smooth opening and closing and use more Advantage easily；

2, it is arranged with convex shoulder on the two side of bar shaped convex body, there is structure relatively stable Advantage；

3, by arranging annular convex shoulder, it is simple to the crawl of housing, there is dismounting more convenient Advantage.
