Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
The manual control mechanism of a kind of tube shaped electric machine as shown in Figures 1 to 4, including the first end cap 1 He being equipped with
Second end cap 2, is provided with, between the first end cap 1 and the second end cap 2, the sprocket wheel 4 being fixed on sprocket shaft 3, sprocket wheel 4 is arranged with
Chain (not shown), chain stretches out in the first end cap 1 and outside of the second end cap 2.
The medial wall of the second end cap 2 is fixedly connected with friction pulley 5, and specifically, the medial wall of the second end cap 2 is convexly equipped with set
Ring 21, friction pulley 5 is arranged at the outside of the collar 21.In order to avoid friction pulley 5 occurs rotation, the outer wall of the collar 21 to be provided with some limits
Position protruding 22, the inwall of friction pulley 5 is provided with some stopper slots 51 coordinated with spacing preiection 22 spline.
In order to improve axiality when sprocket shaft 3 is installed, and reduce the frictional resistance that sprocket shaft 3 is suffered when rotating,
Sprocket shaft 3 is inserted in the collar 21, and is provided with bearing 6 between sprocket shaft 3 and the collar 21.
Sprocket wheel 4 is fixedly connected with at least one spring steel plate 7, it is preferable that sprocket wheel 4 is provided with two spring steel plates 7, two
Spring steel plate 7 is set in parallel, and arranges two spring steel plates 7, it is possible to improve stability of the present utility model further with reliable
Property.
The outer wall of friction pulley 5 circumferentially arranged with some with spring steel plate 7 corresponding matching confined planes 52, spring steel plate 7 with
It is freely rotatable that confined planes 52 coordinates to limit sprocket wheel 4.Specifically, some confined planes 52 are distributed in friction pulley end to end
On the periphery wall of 5, some confined planes 52 coordinate in class regular prism face structure.
Friction pulley 5 is inserted into the inside of sprocket wheel 4, and the two ends of spring steel plate 7 are fixed on the inwall of sprocket wheel 4, specifically,
The two ends of spring steel plate 7 are inserted on the inwall of sprocket wheel 4 respectively, and corresponding confined planes 52 is close at the middle part of spring steel plate 7.
It is provided with on the inwall of sprocket wheel 4 and supports the bracer 41 coordinated, a bracer 41 and friction pulley 5 points with spring steel plate 7
Not being positioned at the both sides of spring steel plate 7, a bracer 41 is for playing a supportive role to spring steel plate 7, and the elasticity improving spring steel plate 7 is multiple
Position effect.
When manually pulling chain, under the effect of confined planes 52, sprocket wheel 4 can be applied by friction pulley 5 by spring steel plate 7
Certain resistance so that sprocket wheel 4 can not rotate easily；When the pulling force applying chain is more than the resistance of friction pulley 5, now bullet
Spring steel disc 7 will produce a certain amount of deformation along the radial direction of friction pulley 5 under the mating reaction of sprocket wheel 4 and confined planes 52 so that
Sprocket wheel 4 rotates relative to friction pulley 5, thus has driven sprocket shaft 3 to rotate；When unclamping chain, the pulling force of sprocket wheel 4 is disappeared by chain
Losing, now spring steel plate 7 is close to confined planes 52 under its own resilient effect again so that sprocket wheel 4 cannot be relative to friction pulley 5 turns
Dynamic.
In sum, when not pulling chain, due to the mating reaction of spring steel plate 7 with friction pulley 5, the rotation of sprocket wheel 4
Need to overcome the active force between spring steel plate 7 and friction pulley 5, therefore, it is possible to the position degree of sprocket wheel 4 is effectively ensured, it is to avoid chain
There is less desirable rotation in wheel shaft 3, it is ensured that the normal work of tube shaped electric machine.
The above is only better embodiment of the present utility model, therefore all according to described in this utility model patent claim
Structure, feature and principle done equivalence change or modify, be all included in this utility model patent claim.
