Description

Knocking device for turning-operated shaft

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knock mechanism that generates a knock sound or a knocking feeling at a specific rotational position when operating an operating shaft that rotates to operate a device such as a gas cock.

The operating mechanism of the gas cock is composed of a coke body in which a rotating valve body or the like is assembled in the body of the gas cock, and an operating mechanism coupled to the body of the gas cock by a rotating shaft for operating the rotating valve body. The operation mechanism includes a base plate fastened to a body having an insertion hole of the operation shaft, and an operation shaft guide provided in parallel with an interval on the front surface of the base plate, and a support hole supporting the operation shaft.

Knock mechanism with knock spring consisting of a knock plate which rotates in conjunction with a control shaft assembled with a steel ball on the front of the control shaft, and a leaf spring that presses the corresponding plate and the steel ball with the control shaft guide. And a predetermined rotational position such as a maximum fire position, a heavy fire position, and the like can be recognized as a knock sound or a sense of knock.

The conventional knock mechanism requires a knock spring because the steel ball is assembled into a hole formed in the knock plate as a part, and requires a large number of parts, which makes the assembly cumbersome and expensive.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a knocking mechanism of a rotary operation shaft which reduces the number of parts and the number of assembly operations and enables cost reduction.

The present invention has an operating shaft guide and a support hole for supporting the rotating operation shaft, the operation shaft guide mounted at intervals between the body of the device to be operated by the rotation operation shaft, and installed at the intervals of the operation shaft A knock mechanism of an operating mechanism having a knock mechanism for generating a knock signal at a specific rotational position,

Recesses or projections provided in the operation shaft guide, knock plates arranged at the intervals, rotatably interlocked with the rotation operation shaft, and movably mounted in the axial direction, and installed on the knock plate, A projection or recess coupled to the recess or projection in a specific rotational position and a spring for pressing the knock plate to the operation shaft guide.

The present invention replaces the steel ball by forming a protrusion or recess on one side of the knock plate or the operation shaft guide, and forming a recess or protrusion on the other side. Because of this, the knock mechanism can be configured with a minimum number of parts, and at the same time, assembly is easy. In addition, since the projections or recesses can be easily formed on the knock plate or the operation shaft guide by press molding or the like, the knock mechanism can be manufactured at low cost.

In the structure of Claim 2, since the spring which presses an ignition lever to a base board can be substituted by the spring which presses a knock board to an operation shaft guide, the number of parts can be further reduced.

In the constitution of claim 3, when the projection engages with the recess, the knock plate rapidly moves in the rotational direction as much as the clearance between the rotational operation shaft and the central hole, and the projection strikes the edge of the recess, so that a knocking sound is surely generated.

In the configuration of claim 4, the projection is a hemispherical projection that is expanded by a press, and the recessed portion can be inexpensive and practical by punching in a circular shape.
