Abstract

The utility model discloses a gas table core measurement chamber cap for form the measuring room casing with the combination of measuring room shell, and support the core on the shell is showed in the gas through the lug on the measurement chamber cap body lateral surface, the lug forms angle on the caping of trapezoidal measurement chamber cap body, and measurement chamber cap body is setting up the region of lug has the bodiness part of increase in thickness that has regional for the next -door neighbour, and this bodiness part is outstanding outside at measurement chamber cap body to by the outside attenuate gradually of lug, and through the circular arc transition between bodiness part and the lug. Preferred, the bodiness part bodiness volume bodiness value at big position is more than or equal to the half who closes on regional thickness, bodiness part the caping plane top edge of measurement chamber cap body apart from the lug apart from more than or equal to 15mm. The beneficial effects of the utility model are that, the gas meter core supports firmly, and the warehousing and transportation spoilage is low, and the fruitless labour is few, and economic benefits is good.

Description

Gas meter movement metering chamber cap

Technical field

This utility model patent relates to a kind of gas meter movement, particularly a kind of gas meter movement metering chamber cap。

Background technology

The metering of combustion gas gas consumption is realized by gas meter, and gas meter includes movement sum counter, and movement is arranged in watchcase, and enumerator is located at outside watchcase。Movement includes measuring room and gas consumption shifter, and the transform linear motion of epithelium in measuring room is rotary motion output by crank connecting rod mechanism by shifter, with by the accumulative gas consumption of enumerator。Measuring room housing is made up of main casing and the metering chamber cap being sealedly connected on main casing both sides。Measuring room housing is supported on gas meter housing by the projection on the measuring room lid of both sides, the weight of measuring room acts on gas meter shell by projection, therefore, projection need to have some strength except itself except must also and metering chamber cap between there is good bonding strength, to avoid vibrations in the transportation of gas meter to damage measuring room shell。But existing metering chamber cap is formed as thin wall plastics usually by injection moulding, gas meter usually destroys the connecting portion between projection and shell body in storage and transport process because of vibrations, have to change measuring room shell becoming housing to tear, cause Reseal, the fruitless labour such as adjustment even again。For this reason, it may be necessary to existing metering chamber cap is improved。

Summary of the invention

The purpose of this utility model is aiming at the deficiencies in the prior art, it is provided that a kind of gas meter movement metering chamber cap。This metering chamber cap, by the connecting portion of lid body with projection is formed the structure of partial thickening, to increase bonding strength therebetween, improves resisting breakage ability, reduces fruitless labour, improve business efficiency。

For achieving the above object, this utility model adopts the following technical scheme that。

A kind of gas meter movement metering chamber cap, for forming measuring room housing with the combination of measuring room shell, and is supported on movement on gas meter, flow meter watchcase by measuring the projection on chamber cap outer body face；Projection forms angle on the caping of trapezoidal metering chamber cap body, metering chamber cap body has in the region arranging described projection and has, relative to immediate area, the thickening that thickness increases, this thickening highlights in metering chamber cap body exterior, and outwards thinning gradually by projection, and between thickening and projection, pass through arc transition。

Adopt this utility model of preceding solution, projection and lid body is made to form good bonding strength by progressively thickening mode, the mode simultaneously connected by arc transition forms the attachment structure of unstressed or little stress, the ability resisting vibration limits can be effectively improved, damage hidden danger is torn in the vibrations reduced or eliminate in storage and transport process, thus eliminating or reducing fruitless labour, increase economic efficiency。And thickened section is located at hull outside, do not affect the revolution volume of measuring room, it is simple to measuring room designing and calculating, improve design efficiency and metering precision。

Preferably, the described maximum position of thickening amount of swelling thicken value more than or equal to 1/2nd of close region thickness。, while improving bonding strength, to save material consumption。

Preferably, described thickening in the caping plane top edge distance from projection of metering chamber cap body be more than or equal to 15mm。Improve bonding strength further。

The beneficial effects of the utility model are, gas meter movement firm supporting, accumulating spoilage is low, and fruitless labour is few, good in economic efficiency。

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described, but therefore this utility model is not limited among described scope of embodiments。

Referring to Fig. 1, Fig. 2, a kind of gas meter movement metering chamber cap, for forming measuring room housing with the combination of measuring room shell, and by measuring the projection 2 on chamber cap body 1 lateral surface, movement is supported on gas meter, flow meter watchcase；Two projections 2 are respectively formed at two upper angles of the caping of trapezoidal metering chamber cap body 1, metering chamber cap body 1 has in the region arranging described projection 2 and has, relative to immediate area, the thickening 1a that thickness increases, this thickening 1a highlights outside metering chamber cap body 1, and outwards thinning gradually by projection 1, and pass through arc transition between thickening 1a and projection 2。

Wherein, the maximum position of thickening 1a amount of swelling thicken value h more than or equal to 1/2nd of close region thickness H；Thickening 1a at the caping plane top edge distance B from projection 2 of metering chamber cap body 1 be more than or equal to 15mm。

Preferred embodiment of the present utility model described in detail above。Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work。Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims。
