Abstract
The utility model relates to a handle connecting shaft which belongs to the technical field of electric appliance operating mechanisms and comprises a handle, a transition shaft and a moving contact, wherein the handle and the moving contact are connected by the transition shaft; one end of the handle is provided with an operating handlebar, the other end of the handle is semicircular, and a shaft hole is arranged in the center of the semicircle; one end of the moving contact is provided with a half shaft hole, and the other end is also provided with a half shaft hole which is provided with a hang spring block shaft; and the transition shaft is in stepped cylinder shape, one end of the transition shaft is provided with an optical shaft while the other end is provided with a step shaft, and the transition shaft penetrates through the shaft hole of the handle and the half shaft holes of the moving contact to position and connect the handle and the moving contact. The handle connecting shaft has the beneficial effects of being simple in structure, solving the defects including the easy-breaking of the handle shaft and the easy-falling of the moving contact after being changed into a way that a metal transition shaft is adopted for connection and transmission, alleviating the abrasion of the handle, enhancing the flexibility and the matching precision of the mechanisms, and meeting the requirements of improving the reliability of the actions of the mechanism and prolonging the service life.
Description
Technical field
The utility model relates to a kind of handle connecting axle, belongs to the operating mechanism for electrical appliances technical field.
Background technology
Realize the on/off switch operation of circuit breaker, need moving contact be passed in the operation of circuit breaker on/off switch by engineering plastics system handle, because the restriction of structure space and size, the boss axle form of homogeneity material is adopted in the junction of handle and moving contact, the size of boss axle is thinner, handle junction intensity is low, and is easy to wear easily broken, and junction, wearing and tearing back moving contact easily comes off.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of handle connecting axle.
The technical scheme that its technical problem that solves the utility model adopts is: comprise handle, transition axis, moving contact, handle is connected by transition axis with moving contact.
Handle is connected by transition axis with moving contact.
The design of handle one end has the operator handle, other end semicircular in shape, and semicircle center is shaped on axis hole.
The first end of movable contact is shaped on the semiaxis hole, and the other end also is shaped on to be equipped with on semiaxis hole and the semiaxis hole hangs the spring gear shaft.
It is cylindric that transition axis is ladder, and an end is an optical axis, and the other end is the step axle.
Transition axis passes the axis hole and the moving contact semiaxis hole of the semicircle center of handle, with handle with the moving contact location be connected
The beneficial effects of the utility model are simple in structure, become by after the metallic transition axis connection transmission operation, it is low easily broken to have solved handle boss axle place intensity, the caducous defect of moving contact, the wearing and tearing of handle have been alleviated, strengthened the flexibility and the quality of fit of mechanism, reached and improved the moving reliability of doing of mechanism and the requirement in life-span.
