Problems solved by technology

[0003] When using the magnetic suction method for fastening and fixing, due to the limited magnetic suction force, it is difficult to achieve high sealing requirements, and the protection level is generally below IP54. For some special environments (such as high temperature, high humidity, high salt spray concentration) environment) safety protection is not up to
The buckle fastening method is used, because it needs to be opened and closed repeatedly, the buckle can only be designed with a small amount of fastening, and the load it can bear is very small. After a long time of use, the stress relaxation may cause the buckle to trip and fail. invalidate the seal

Abstract

The invention relates to the field of the metering instrument product, and specifically relates to a metering instrument controller capable of opening / closing a cover plate through rotation, and a gasmeter. The controller comprises a controller lower shell connected to a base metering instrument and an upper shell cooperatively assembled with the lower shell; the controller comprises a battery bunker, the upper shell comprises a upper shell body and a battery bunker cover buckled on ten upper shell body in an open / close way; the controller further comprises a fixing button for fixing the battery bunker cover on the upper shell body; the battery bunker cover comprises a first fixing part, a second fixing part corresponding to the first fixing part is arranged on the upper shell body; and the fixing button fixes the battery bunker cover on the upper cover body by penetrating the first fixing part and the second fixing part. The gas meter comprises the controller and the base instrument.The technical scheme disclosed by the invention can satisfy the high protection requirement in the use process of the metering instrument, and has the technical advantages of being simple in operation and smart in design.

Description

technical field [0001] The invention relates to the field of intelligent measuring instrument products, in particular to a metering instrument controller for rotating and opening and closing a cover plate and a gas meter with the controller. Background technique [0002] As we all know, most of the existing measuring instruments (such as gas meters, water meters, etc.) are powered by batteries due to safety factors, and the DC battery is installed inside the battery compartment of the controller. In order to facilitate battery replacement, the existing battery compartment design is usually With the cover plate design, when the battery needs to be repaired or replaced, it is only necessary to open the battery compartment cover to operate the internal battery. In the prior art, the design of the cover plate of the battery compartment mostly adopts the method of magnetic attraction or buckle fixing. [0003] When using the magnetic suction method for fastening and fixing, due ...
