Document Type and Number:
WIPO Patent Application WO/2022/110625
Kind Code:
A1
Abstract:
The present invention relates to a diaphragm assembly, comprising a diaphragm structure and a transmission member connected to the diaphragm structure and used for driving the diaphragm structure to move. The transmission member comprises a transmission shaft and a connection plate connected onto the transmission shaft, the connection plate comprises a first part and a second part which are connected in sequence, the second part and the first part are arranged obliquely, and a limiting column is arranged symmetrically at the tail end of the second part along the width direction of the second part; a positioning sliding table is arranged symmetrically, along the width direction of the second part, on the side of the second part facing towards the diaphragm structure, and the diaphragm structure comprises a boss slideway which is arranged symmetrically and matches the positioning sliding table. According to the diaphragm assembly of the present invention, by means of matching between the positioning sliding table and the boss slideway, a certain guiding effect is achieved when the transmission member drives the diaphragm structure; in addition, it is beneficial to ensuring that the transmission member stably transmits power to the diaphragm structure, ensuring that the diaphragm structure is moved periodically and stably, and thus guaranteeing the accuracy of an assembled gas meter.
