SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a gas table upper cover and with counter bottom plate connection structure to among the solution prior art, gas table upper cover is complicated with counter bottom plate riveting process, and production efficiency is relatively poor, and riveting quality influence factor is more the scheduling problem.

The technical scheme is as follows:

the utility model provides a gas table upper cover, includes the lid, one side surface of lid has heavy platform, and its key lies in: in the counter sink area, the cover body is provided with at least two convex hulls, and the convex hulls and the cover body are integrally formed.

By adopting the scheme, the follow-up convex closure can be directly riveted and fixed with the counter bottom plate, the screw welding process in the traditional process is saved, and the cover body can be ensured to have better structural strength because the convex closure and the cover body are integrally formed.

Preferably, the method comprises the following steps: the convex hull is of a hollow structure. By adopting the scheme, the quick riveting is convenient, and the riveting impact force is reduced.

The utility model provides a gas table upper cover and counter bottom plate connection structure which the key lies in: the counter bottom plate is provided with punched holes corresponding to the convex hulls one to one, and the counter bottom plate is fixed to the cover body through the punched holes and the convex hulls in a riveting mode. By adopting the scheme, the welding procedure of riveting screws is reduced, the production cost is reduced, the riveting and assembling time of the bottom plate and the upper cover of the counter is greatly shortened, and the riveting quality is improved.

Preferably, the method comprises the following steps: the convex hulls are four and distributed in a rectangular shape, and the convex hulls are close to the corners of the sinking platform. By adopting the scheme, the riveting stability is further improved, and the situation that the whole body is loosened due to poor riveting individually is prevented.

Preferably, the method comprises the following steps: the convex hull is cylindrical, and the outer edge of the end face of the convex hull is provided with an arc chamfer. By adopting the scheme, punching holes on the counter are convenient to align the convex hulls and then put into the sinking platform, after the counter is riveted on the other hand, the appearance is in a flat round shape, burr corners can not be formed, and the counter has good appearance quality.

Compared with the prior art, the beneficial effects of the utility model are that:

adopt the utility model provides a gas table upper cover and with counter bottom plate connection structure thereof omits traditional riveting screw welding process, can improve gas table upper cover and counter bottom plate riveting efficiency, have better riveting fixed quality simultaneously, be favorable to improving gas table production efficiency and whole quality.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 5, the gas meter upper cover and the connection structure of the gas meter upper cover and the counter bottom plate, both the gas meter upper cover and the counter bottom plate are metal members, wherein the gas meter upper cover mainly includes a cover body 1, as shown in fig. 3 and 4, a sinking platform 10 is provided on an outer surface of one side of the cover body 1, at the same time, in a region of the sinking platform 10, the cover body 1 is provided with at least two convex hulls 11, the convex hulls 11 are in an evenly distributed posture with respect to a center of the sinking platform 10 in a normal condition, the convex hulls 11 are vertically and outwardly protruded with respect to the cover body 1, and the protrusion height is greater than the depth of the sinking platform 10.

Protruding package 11 passes through the tensile shaping of mould integrative punching press with lid 1 in this application, and protruding package 11 is hollow structure.

The connection structure in this application mainly includes above-mentioned lid 1 to and counter bottom plate 2 that suits with heavy platform 10, counter bottom plate 2 bottom thickness is unanimous basically with the degree of depth of heavy platform 10 promptly, and the bottom profile adapts to each other, has the punching a hole 20 with convex closure 11 one-to-one on counter bottom plate 2 simultaneously, and counter bottom plate 2 is through punching a hole 20 and convex closure 11 riveting fixed to on the lid 1.

In order to further improve the connection stability of the counter bottom plate 2, four convex hulls 11 are provided and distributed in a rectangular shape in the present embodiment, the sinking platform 10 is substantially rectangular, and the four convex hulls 11 are respectively close to four corners of the sinking platform 10.

As shown in fig. 3 and 4, in the present embodiment, the convex hull 11 is cylindrical, and the outer edge of the end surface has an arc chamfer, which makes it easier to pass through the punched hole 20, and can maintain a better and complete appearance quality after the punching and riveting are completed.

Referring to fig. 1 to 5, a gas meter upper cover and its and counter bottom plate connection structure, cover integrated into one piece convex closure 11 on the gas meter through the mould is direct in the production process, when carrying out the assembly of gas meter bottom plate, only need with lid 1 with the gesture of heavy platform 10 after fixed up, put to heavy platform 10 behind the convex closure 11 with the 20 that punch a hole of counter bottom plate 2, after aligning convex closure 11 with towards riveting equipment, connect between the two, compared with the conventional art, convenient province, be favorable to improving the whole production efficiency of gas meter.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
