Embodiment

[0007] Embodiment: A kind of pre-fee gas meter, adding coin linkage mechanism, gas purchase metering transmission mechanism, gas consumption feedback metering transmission mechanism and ventilation braking mechanism to the film type gas meter, when the metering coin is put into the coin slot in the meter, the The two originally separated pallets 3 and 4 with notches are connected together, and the key of the rocker arm 1 is manually pressed to make the active pallet drive the passive pallet to rotate half a circle through the metering coin, and the rotation of the passive pallet drives the gas purchase through the gear system and corresponding accessories. The indicator needle moves laterally and indicates the corresponding gas purchase volume, and at the same time, the ventilation brake mechanism is released from the brake constraint, the main wheel of the gas meter can rotate freely, and the user can use gas at any time. With the increase of gas consumption, the pointer on th...

Abstract

The invention discloses a pre-paid gas meter. A metering coin is put into the meter through a coin port and then connects two originally separated clip boards with notches. A swinging arm is manually pressed to make the driving clip board drive the driven clip board for half a circle through the metering coin, rotation of the driven clip board makes the gas purchasing pointer move transversely and indicate the corresponding gas purchasing amount through a gear system and corresponding accessories, and makes a ventilation braking mechanism release braking limit, then the main wheel of the gas meter can rotate freely, and the user can use gas at any time. As increase of gas consumption, the pointer on the gas meter gradually moves to the initial position. When the gas consumption reaches the gas purchase amount limit, the pointer reaches zero point, a knockout beam arranged at the lower part of the pointer drives the ventilation braking mechanism to automatically lock the driving wheel of the film type meter body to stop gas supply. Advantages of the invention are reasonable structure, convenient toll and managing, human power and cost saving, accurate metering, safety and reliability.

Description

technical field [0001] The invention relates to a prepaid gas meter. Background technique [0002] Existing gas meters are installed indoors and need to be regularly checked and charged, which is not conducive to unified management. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect, a kind of prepaid gas meter is provided. [0004] The technical solution of the present invention is: a pre-charged gas meter, characterized in that a coin linkage mechanism, a gas purchase metering transmission mechanism, a gas consumption feedback metering After putting into the coin slot in the watch, connect the two originally separated pallets with gaps, manually press the button of the rocker arm to make the active pallet drive the passive pallet to rotate for half a circle through the metering coin, and the rotation of the passive pallet passes through the gear system and the corresponding The attachment makes the gas purchase ...
