Problems solved by technology

Since the battery is used for power supply, when the battery power is low, the battery cover needs to be opened to replace the battery. If the battery cover is fixed with screws, the opening and closing of the battery cover needs to be done with tools, which is cumbersome and inefficient; if the battery cover is fixed by buckles To close the cover, you need to press the battery cover hard, and to open the cover, you need to break the battery cover forcibly. The opening and closing operation will easily lead to the deformation of the buckle and the battery cover, and the strength of the buckle will be weakened after repeated opening and closing, which will affect the closing of the battery cover. cover effect

Embodiment 1

[0047] refer to figure 1 , 2 , the meter controller proposed by Embodiment 1 of the present invention includes a box body 100, a control unit, and a power supply unit 300 for supplying power to the control unit. Cover 200, wherein the power supply unit 300 generally refers to a small power storage device that can provide electric energy, usually a battery, and the meter in this embodiment is a gas meter. Considering the safety of the gas meter, an independent power supply unit 300 is used as the control unit For power supply, when the power supply unit 300 is insufficient, it is necessary to open the power supply cover 200 for replacement. The rear side of the power supply cover 200 of this embodiment is connected to the box body 100 through the rotating shaft. Flip around the axis of rotation on the box body 100. When the power cover 200 is opened, it remains connected to the box body 100 to prevent the problem of falling and losing the power cover 200 after opening; the po...

Embodiment 2

[0058] The difference between this embodiment and the first embodiment is that an elastic member is provided on the box body in this embodiment, and when the driving latch is separated from the box body, the elastic member pushes the power supply cover to open. For example: a spring or an elastic push rod is installed on the upper surface of the box body in conjunction with the power cover. When the power cover is locked on the box body, the upper end of the spring or elastic push rod is against the power cover. Push the lever up to open the power supply cover.

Embodiment 3

[0060] The difference between this embodiment and Embodiment 1 is that the elastic part of this embodiment is a torsion spring, and the torsion spring is set on the rotating shaft at the rear side of the power supply cover. One end of the torsion spring is connected to the power supply cover, and the other end of the torsion spring is connected to the On the box body, when the power cover is locked on the box body, the torsion spring is compressed and twisted, and when the latch part is separated from the box body, the torsion spring releases the torsion force to pop the power cover off.

[0061] In addition to gas meters, the embodiments of the present invention can also be applied to other metering instruments such as electricity meters, water meters, and heat meters.

Abstract

The invention discloses a meter controller, belongs to the technical field of metering equipment, and solves the problem that a battery cover of an existing meter controller is not convenient to openor close. The meter controller comprises a box body, a control portion and a power supply portion for supplying power for the control portion. The box body has a power supply cabin for accommodating the power supply portion and a power supply cover for covering the power supply cabin. The power supply cover is provided with a pin. The box body is provided with a slot. The power supply cover or thebox body is provided with an elastic element. The pin is inserted into the slot to enable the power supply cover to be locked to the box body; and when the pin is driven to separate from the box body, the elastic element drives the power supply cover to open. According to the scheme, the power supply cover is locked to the box body through the movable pin; the cover can be opened just by drivingthe pin to separate from the box body, and the opening and closing operation of the power supply cover can be finished quickly without assistance of tools; and an operation worker can finish opening and closing operation of the power supply cover with a single hand, thereby saving time and energy.

Description

【Technical field】 [0001] The invention relates to the technical field of metering equipment, in particular to a controller of a meter. 【Background technique】 [0002] Existing meters (such as gas meters) include a base meter and a controller installed on the base meter. The controller is mainly used to control the work of the base meter, read cards, and display metering data. To ensure safe use, the controller uses a battery The power supply maintains the work. The controller has a battery compartment for installing the battery. After the battery is installed, cover the battery cover. The battery cover is fixed by screwing or snapping. Since the battery is used for power supply, when the battery power is low, the battery cover needs to be opened to replace the battery. If the battery cover is fixed with screws, the opening and closing of the battery cover needs to be done with tools, which is cumbersome and inefficient; if the battery cover is fixed by buckles To close the ...
