Drawer type battery case

Abstract

The invention relates to a battery case, in particular to a drawer type battery case which comprises a drawer case, a positive plate, a negative spring and an outer case, wherein the drawer case is connected with an output wire; a battery cavity capable of accommodating a battery is formed in the drawer case; the positive plate and the negative spring are arranged at two inner ends of the battery cavity; the drawer case is arranged in the outer case; the outer walls at both sides of the outer case are provided with bayonets; the outer walls at both sides of an end cover plate of the drawer case are provided with elastic clamps buckled with the bayonets; the edge of the inner wall of the end cover plate is provided with a sealing gasket; the output wire is led out of a wire outlet hole in an outer case shell; and the wire outlet hole and the output wire are sealed through a sealing column. Due to the adoption of the structure, the invention has the advantages that: the drawer type battery case is easy to manufacture, and has low cost and high moisture resistance; and most importantly, the battery can be replaced rapidly and conveniently.

Description

technical field [0001] The invention relates to a battery box for an intelligent gas meter or an intelligent water meter, in particular to a drawer-type battery box which is convenient to replace the dry battery in the box, and can prevent positive and negative electrodes from being reversed and sealed. Background technique [0002] In the smart gas meter and smart water meter industries, the installation environment is relatively humid and relatively narrow. At present, in order to ensure the application of smart gas meters and smart water meters in daily life, most of the battery installation structures used are to install dry batteries in a semicircular groove, and then cover a cover plate on it (the same as the battery installation method of most remote control panels. same). This method is easy to operate, but it is not conducive to the sealing of the dry battery, the ability to resist moisture is not strong, and the service life of the dry battery is seriously shorten...

AI Technical Summary

Problems solved by technology

This method is convenient to operate, but it is not conducive to the sealing of dry batteries, the ability to resist moisture is not strong, and the service life of dry batteries is severely shortened

[0003] In order to prolong the service life of the dry battery, the existing technology is to completely seal the dry battery in the casing, but when replacing the battery, professionals must use professional tools, and the operation is extremely inconvenient

Once the battery is out of power, the smart gas meter or smart water meter will not work normally, which will affect the user's use and increase the maintenance cost of the smart gas meter or smart water meter

[0004] To sum up, the battery boxes for smart gas meters or smart water meters in the prior art cannot meet the needs of battery boxes that can prevent moisture and facilitate battery replacement.
