Abstract
The invention discloses a handle device which has a dustproof function and is capable of two-way rotation. The handle device comprises an outer hand wheel and an inner hand wheel, wherein the inner hand wheel is positioned in the outer hand wheel, the inner hand wheel and the outer hand wheel are connected through two symmetrical rotating shafts, a U-shaped hole is formed in the circumference of the outer hand wheel, a handle which is connected with the inner hand wheel is arranged through the U-shaped hole, the handle is operated, so that the inner hand wheel is rotated in the outer hand wheel through the rotating shafts, and a main shaft is connected to the center of the circumference of the outer hand wheel. According to the handle device which has the dustproof function and is capable of two-way rotation, the handle device has the dustproof function, two-way rotation control can be realized, when the inner hand wheel is driven to rotate by a handle lever, a dustproof blocking piece is pushed to slide in a chute of the outer hand wheel by the handle lever, and a clearance in a hand wheel device is dynamically sealed, so as to prevent foreign matter and dust from falling in the handle device, so that the traditional installation space of two one-way rotating handles for two-way control is reduced, the utilization efficiency of the handle is improved, and the reliability of a mechanism is increased.
Description
Technical field
The invention belongs to locomotive control technical field of electric appliances is and in particular to one kind has dust reduction capability and can Double-directional rotary

Background technology
Handle apparatus are widely used in locomotive control electric equipment, by the work of the position control locomotive of turning handle
Make state, some handle apparatus are one-directional rotation at present, span of control is limited, to control both direction, then needs two handles
Device, causes equipment volume excessive, mechanism is loaded down with trivial details；In addition there is necessary stroke gap between handlebar and handwheel, have different
Thing falls into inside handle apparatus, causes the clamping stagnation of handle apparatus or destruction so as to reliability reduces, and brings hidden for safe handling
Suffer from.
Content of the invention
It is an object of the invention to provide a kind of have dust reduction capability and can Double-directional rotary handle apparatus, only pass through one
Individual handle apparatus can achieve Double-directional rotary function.
The technical solution adopted in the present invention is: have dust reduction capability and can Double-directional rotary handle apparatus, including outer
Handwheel and be located at outer hand wheel within interior handwheel, be connected by two symmetrically arranged rotating shafts between interior handwheel and outer hand wheel,
The provided circumferentially about of outer hand wheel has u shape hole, u shape hole is provided with the handle being connected with interior handwheel, control crank makes interior handss
By rotating shaft in outer hand wheel inner rotation, the circle center of outer hand wheel is connected with main shaft to wheel.
The feature of the present invention also resides in:
U shape in the hole portion on outer hand wheel offers chute, is provided with dynamic mobile and prevents foreign body from falling into the right-hand side in chute
Dust-proof catch within wheel, handle passes through dust-proof catch and the hole shape with dust-proof catch is adapted.
The chamfering being adapted with handle shape is provided with the perforate of dust-proof catch.
It is additionally provided with back-moving spring between interior handwheel and outer hand wheel.
Between outer hand wheel and main shaft, the cone bolt by being arranged within outer hand wheel is realized connecting.
The invention has the beneficial effects as follows: the present invention have dust reduction capability and can Double-directional rotary handle apparatus have anti-
Dirt function and enable two-way rotation and control, handlebar drive in hand wheel rotating when, handlebar promotes dust-proof catch in outer handss
Move in the chute of wheel, dynamic sealing is stopped the gap on wheel apparatus, stop foreign body and dust from falling into inside handle apparatus, and prevent
Chamfering in dirt catch perforate ensures that handlebar smoothly can not produce catching phenomenon relative to slip with dust-proof catch, not only reduces
It is conventionally used to the installing space of two one-directional rotation handles of double-direction control, and increases handle utilization ratio, improve mechanism
Reliability.

Specific embodiment
With reference to specific embodiment, the present invention is described in detail.
The present invention provide have dust reduction capability and can Double-directional rotary handle apparatus structure as depicted in figs. 1 and 2,
Including the outer hand wheel 3 being connected by two symmetrical rotating shafts 4 and interior handwheel 6, interior handwheel 6 is threaded connection with handle, handss
Handle is made up of connected handle head 1 and handlebar 2, is provided with two back-moving springs 8, in the right-hand side between outer hand wheel 3 and interior handwheel 6
It is threaded connection equipped with dust-proof catch 5, interior handwheel 6 and handlebar 2 on the chute of wheel 3, and handlebar 2 passes through dust-proof catch
Perforate on 5, main shaft 7 passes through to bore the connection of bolt 9 realization and outer hand wheel 3.
Referring to Fig. 1 and Fig. 2, the present invention have dust reduction capability and can Double-directional rotary handle apparatus, interior handwheel 6 passes through
Two symmetrical rotating shafts 4 be connected with outer hand wheel 3 it is achieved that interior handwheel 6 with respect to outer hand wheel 3 around x-axis rotation, the same to time limit
Handwheel 6 motion in other directions with respect to outer hand wheel 3 in fixed；Main shaft 7 passes through to bore bolt 9 and formed with outer hand wheel 3 to be connected, handle
Bar 2 is threaded connection with interior handwheel 6, and the stroke that u-shaped groove dimension limitation on outer hand wheel 3 handlebar 2 rotates around x-axis is empty
Between, two back-moving springs 8 are installed between outer hand wheel 3 and interior handwheel 6 it is achieved that interior handwheel 6 occurs to turn with respect to outer hand wheel 3
Automatically reseting after dynamic, by above structure, finally realizes handlebar 2, outer hand wheel 3, interior handwheel 6, main shaft 7 turn together about y-axis
Dynamic, and interior handwheel 6 with respect to outer hand wheel 3 around the rotation of x-axis and reset, two kinds rotate between separate, non-interference, real
Existing handle Double-directional rotary operation.
Referring to Fig. 2 and Fig. 3, the handlebar 2 of the present invention is threaded connection with interior handwheel 6, and handlebar 2 can drive interior handss
Wheel 6 rotates around x-axis, and realizes and the relatively rotating of outer hand wheel 3, and the u-shaped groove size on outer hand wheel 3 has reserved handlebar 2 around x-axis
Rotate stroke space, then exist between handlebar 2 and outer hand wheel 3 width be 11mm, area be 77mm2 gap, in order to
Seal this gap, outer hand wheel 3 chute built with dust-proof catch 5, dust-proof catch 5 follows the rotation of handlebar 2 in outer hand wheel 3
Chute in move, the gap between handlebar 2 and outer hand wheel 3 is realized with dynamic sealing, stops foreign body from falling in handle apparatus
Portion, on dust-proof catch 5, the chamfering of circular hole both sides ensures that handlebar 2 does not successfully produce clamping stagnation with dust-proof catch 5 relative to slip
Phenomenon.
