Technical field
The invention belongs to locomotive control technical field of electric appliances, be specifically related to a kind ofly there is dust reduction capability and can the handle apparatus of Double-directional rotary.
Background technology
Handle apparatus is widely used in locomotive control electric equipment, and by the duty of the position control locomotive of turning handle, some handle apparatus are one-directional rotation at present, range of control is limited, to control both direction, then needs two handle apparatus, cause equipment volume excessive, mechanism is loaded down with trivial details; There is necessary stroke gap in addition between handlebar and handwheel, have foreign matter and fall into handle apparatus inside, cause clamping stagnation or the destruction of handle apparatus, its reliability is reduced, for safe handling brings hidden danger.
Summary of the invention
The object of the present invention is to provide and a kind ofly there is dust reduction capability and can the handle apparatus of Double-directional rotary, only can realize Double-directional rotary function by a handle apparatus.
The technical solution adopted in the present invention is: have dust reduction capability and can the handle apparatus of Double-directional rotary, comprise outer hand wheel and be positioned at the handwheel of outer hand wheel inside, interior handwheel is connected by two symmetrically arranged rotating shafts with between outer hand wheel, outer hand wheel be circumferentially provided with U-shaped hole, the handle be connected with interior handwheel is provided with through U-shaped hole, control crank makes interior handwheel by rotating shaft in outer hand wheel inner rotation, and the circle center of outer hand wheel is connected with main shaft.
Feature of the present invention is also:
Inside, U-shaped hole on outer hand wheel offers chute, is provided with dynamic mobile and prevents foreign matter from falling into the dust-proof catch of outer hand wheel inside in chute, and handle passes dust-proof catch and adapts with the hole shape of dust-proof catch.
The perforate of dust-proof catch is provided with the chamfering adapted with handle shape.
Also back-moving spring is provided with between interior handwheel and outer hand wheel.
Cone bolt by being arranged at outer hand wheel inside between outer hand wheel and main shaft realizes connecting.
The invention has the beneficial effects as follows: of the present invention have dust reduction capability and the handle apparatus of Double-directional rotary can have dust reduction capability and can realize two-way rotation and control, in handlebar drives during hand wheel rotating, mobile in the chute that handlebar promotes dust-proof catch handwheel outside, dynamic seal (packing) is stopped the gap on wheel apparatus, foreign matter and dust is stoped to fall into handle apparatus inside, and chamfering in dust-proof catch perforate ensures that handlebar and dust-proof catch can smooth relative slidings and do not produce catching phenomenon, not only reduce the installing space of two the one-directional rotation handles being conventionally used to double-direction control, and increase handle utilization ratio, improve the reliability of mechanism.
