Description

Diaphragm rotating shaft mechanism

Technical Field

The utility model relates to a gas table technical field specifically is a diaphragm pivot mechanism.

Background

As shown in figure 1, the prior diaphragm rotating shaft mechanism is formed by riveting a diaphragm rotating shaft 1 and a diaphragm oscillating bar 2 together. The upper end 1-1 and the lower end 1-2 of the diaphragm rotating shaft 1 have different structures. One end 1-2 of the diaphragm rotating shaft 1 penetrates through a through hole 2-1 of the diaphragm oscillating bar 2 and is riveted together in an interference manner. The end 1-2 of the diaphragm rotating shaft 1 is complex to process, the processing cost is high, and the structures of the end 1-1 and the end 1-2 are different, so that the direction riveting needs to be fixed during riveting.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a diaphragm pivot mechanism to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a diaphragm pivot mechanism, includes diaphragm pivot and diaphragm pendulum rod, the epaxial blind hole riveting of diaphragm pendulum rod and diaphragm pivot, the diaphragm pivot includes diaphragm pivot main part and the first knurling portion and the second knurling portion that are located its both ends, first knurling portion and second knurling portion structure are unanimous, be provided with little cylinder on the diaphragm pendulum rod.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, relatively old-fashioned diaphragm pivot mechanism, the cost is lower, and production efficiency is higher.
