Description

Counter cover

Technical field

This utility model patent relates to a kind of gas meter counter component, particularly a kind of counter cover。

Background technology

Gas meter, flow meter is the instrument for metering user gas consumption。In view of existing gas meter metering method, the accuracy of metering can be affected by suitably changing or adjust internal structure。For ensureing the safety of gas meter use procedure and metering accuracy, need to carry out adjustment before gas meter dispatches from the factory, lead sealing after the inspection that also need to be exercised supervision by metrological supervision department before as merchandise sales。The counter cover of gas meter generally adopts four screws to fix, and both there is the fixing workload of installation big, and has been unfavorable for that Anti-theft-dismounting structure is arranged。For this reason, it may be necessary to improve。

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 simple in construction, easy for installation, and can conveniently realize the counter cover of tamper。

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

A kind of counter cover, including rectangular cover sandwich type element, the header board of housing is formed with observation window, the medial wall, one end of housing is formed with support platform, and this support platform is for being connected to the connection wing plate back side installing pedestal of enumerator；The housing other end is formed with a barrel shaped structure, and this barrel shaped structure is positioned at enclosure interior, and is extended back by the header board of housing, and the bottom of barrel shaped structure is formed with a screw mounting hole, and the far-end outer face of barrel shaped structure is positioned at the connection wing plate front of described installation pedestal。

Adopt this utility model of preceding solution, during use, the connection wing plate back side installing pedestal being supported on enumerator by the support platform on shell one end shell inwall of counter cover, the drum head outer face by barrel shaped structure of the other end is connected to before the connection wing plate installing pedestal, and fixed by an installation screw, thus it is fixedly connected on installation pedestal。Its simple in construction, easy for installation, and only Anti-theft-dismounting structure need to be set at a position with fixing screw and can realize Anti-theft-dismounting easily。

Preferably, the inwall of the barrel shaped structure side of described housing also forms auxiliary and support platform。So that case is in the support connecting wing plate of fixing threaded end shape mounted in pairs pedestal。

Preferably, described support platform is also formed with reinforcement。To improve the intensity supporting platform, increase the service life。

Preferably, the bucket wall of described barrel shaped structure forms engaging gap。To be located at tamper sealing cap in barrel shaped structure, and it is fastened in gap by the card base on sealing cap, it is prevented that sealing cap is removed easily, further facilitates and realize Anti-dismounting structure setting。

It is further preferred that described housing is at the bunghole part of barrel shaped structure, it is formed with the bolt line structure being made up of housing seamed edge。To facilitate, sealing cap bolt together with calibrating label or lead sealing cotton rope, on housing, is improved tamper performance further。

Further preferred, described bolt line structure seamed edge entity outside the through wires hole on housing and oblique outer groove is constituted。To form concealed formula structure, it is ensured that bolt line difficult drop-off。

The beneficial effects of the utility model are, simple in construction, easy for installation, and can conveniently realize tamper。

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, Fig. 3, Fig. 4, a kind of counter cover, including rectangular cover sandwich type element 1, the header board of housing 1 is formed observation window 2, the medial wall, one end of housing 1 is formed support platform 3, this support platform 3, for being connected to the connection wing plate back side installing pedestal of enumerator, supports and is also formed with reinforcement 3a on platform 3；Housing 1 other end is formed with a barrel shaped structure, it is internal that this barrel shaped structure is positioned at housing 1, and extended back by the header board of housing 1, the bottom of barrel shaped structure is formed with a screw mounting hole 4, and the far-end outer face of barrel shaped structure is positioned at the connection wing plate front of described installation pedestal。Wherein, the inwall of the barrel shaped structure side of housing 1 also forms auxiliary and support platform 5；Housing 1, at the bunghole part of barrel shaped structure, is formed with the bolt line structure being made up of housing 1 seamed edge, and this bolt line structure seamed edge entity outside the through wires hole 7 on housing 1 and oblique outer groove 8 is constituted。

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。
