Abstract
The invention relates to a deviation switch for multi-angle adjustment of an inner wheel. The technical problem that existing deviation switches are complicated in structure and simple in function and cannot achieve the multi-angle adjustment is mainly solved. A deviation mechanism comprises a deviation shaft and a trigger, wherein the trigger comprises a first cam, a second cam and a third cam. The center of a body is provided with a regular-octagonal transmission hole, the deviation shaft is a square shaft, the body detachably penetrates through the deviation shaft through the transmission hole to form circumferential linkage connection, and the first cam, the second cam and the third cam and the microswitch can form circumferential rotating angles of 12 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees or 45 degrees. Due to the fact that the deviation switch adopts a transmission mode that cam pieces are matched with the square shaft in a unique octagonal mode, the cam pieces can be rotated to achieve the multi-angle adjustment according to the demands when the deviation switch is used, and the deviation switch is simple in structure, rich in function and good in using effect.

Detailed description of the invention
For accompanying drawing, embodiments of the invention are described further below:
As shown in the figure, the deviation switch that a kind of interior wheel multi-angle regulates, comprise housing 1, micro-switch 2 and sideslip mechanism, described sideslip mechanism comprises sideslip axle 3, touch part, described shake-up comprises part body 4 and three of being positioned at around described body open 2 passes with described fine motion and press the cam coordinated, first cam 5 respectively, second cam 6 and the 3rd cam 7, the center of described body 4 is provided with the driving hole 8 of positive octagonal star, described sideslip axle 3 is square shaft, described body 4 forms circumference by described driving hole 8 detouchable through described sideslip axle 3 and is connected, the both sides of the first cam 5 are provided with the first cam front surface 51 and the anti-surface 52 of the first cam, the both sides of described second cam 6 are provided with the second cam front surface 61 and the anti-surface 62 of the second cam, the both sides of described 3rd cam 7 are provided with the 3rd cam front surface 71 and the anti-surface 72 of the 3rd cam, and described first cam front surface 51, the anti-surface 52 of first cam, second cam front surface 61, the anti-surface 62 of second cam, the anti-surface 72 of 3rd cam front surface 71 or the 3rd cam from can form any one of six kinds of different circumferential rotational angles between described micro-switch 2.Described six kinds of circumferential rotational angles of difference are respectively 12 °, 20 °, 25 °, 30 °, 35 ° and 45 °.According to such scheme, due to the type of drive that this deviation switch adopts the unique positive octagonal star of cam bit employing to match with square shaft, in use, just the adjustment of multiple angle can be realized by rotating cam sheet as required, structure is simple, and feature richness, result of use is good.
In the present invention, described first cam front surface 51 and micro-switch 2 are the rotational angle of 30 °, and the anti-surface 52 of described first cam is 45 ° of rotational angles with micro-switch 2.Because driving hole 8 is positive octagonal star, front, each three kinds of week side's rotary states in aspect can be realized with square shaft, as shown in Figure 1, touch part is set on sideslip axle 3, first cam 5 cw is close to micro-switch 2, initial position, there is between the front surface 51 of the first cam and micro-switch 2 rotational angle of 30 °, thus realize the control of 30 ° of sideslip angles, again with the first cam 5 on this figure for benchmark, take out touch part and be turned to another side, the rotational angle that the anti-surface 52 of the first cam and micro-switch are 45 ° can be formed, as shown in Figure 4.
In the present invention, described second cam front surface 61 and described micro-switch 2 are the rotational angle of 35 °, and the anti-surface 62 of described second cam and described micro-switch 2 are the rotational angle of 25 °.Be as the criterion with Fig. 1, rotate other angle to be formed as shown in Figure 2, second cam 6 cw is close to micro-switch 2, initial position, has the rotational angle of 35 °, thus realizes the control of 35 ° of sideslip angles between the front surface 61 of the second cam and micro-switch 2, again with the second cam 6 on this figure for benchmark, take out touch part and be turned to another side, the rotational angle that the anti-surface 62 of the second cam and micro-switch 2 are 20 ° can be formed, as shown in Figure 5.
In the present invention, described 3rd cam front surface 71 and described micro-switch 2 are the rotational angle of 20 °, and the anti-surface 72 of described 3rd cam and described micro-switch 2 are the rotational angle of 12 °.Be as the criterion with Fig. 1, rotate last angle to be formed as shown in Figure 3,3rd cam 7 cw is close to micro-switch, initial position, has the rotational angle of 20 °, thus realizes the control of 20 ° of sideslip angles between the front surface 71 of the 3rd cam and micro-switch 2, again with the 3rd cam 57 on this figure for benchmark, take out touch part and be turned to another side, the rotational angle that the anti-surface 72 of the 3rd cam and micro-switch 2 are 12 ° can be formed, as shown in Figure 6.By the setting position of above-mentioned first cam 5, second cam 6 and the 3rd cam 7, in conjunction with driving hole and the foursquare sideslip axle 3 of positive octagonal star, positive and negative totally six kinds of Angle ambiguity forms can be realized, simple and reasonable for structure, easy to use, can when reduce can parts, achieve more abundant operating mode.
Embodiment should not be considered as the restriction to invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
