Abstract
The utility model relates to an electric element, more particularly to a self-locking positioning device for multiple-stage rotary electric elements, dealing with the technical issue of a self-locking positioning device for the multiple-stage rotary electric element. The self-locking positioning device comprises essentially a positioning disk which is fixed on the shell of the electric element, and a twist grip which runs through the top of the rotation axis in the radial direction. The positioning disk has several notches on the edge; the twist grip has a retaining ring on one end, with a return spring between the retaining ring and the rotation axis, and positioning pins on the other end to correspond with the notches. The utility model has advantages that it ensures positioning at multiple stages; no accidental touch will cause misplacement; an O-shaped ring may be added between the positioning disk and the rotation axis, if air-tight is required.
Description
Technical field:
The utility model relates to electric component, relates in particular to a kind of automatic locking positioning device that is applicable to many gears rotary electric element.
Background technology:
Common many gears rotary electric element such as multiband rotary switch, variable potentiometer etc.This class electric component housing is provided with rotating shaft, makes this electric component be positioned at the different operating gear by rotating rotating shaft to certain angle position.Existing this electric component, its positioning of rotating is that armrest rotates rotating shaft to navigate to desired location, there is not self-locking device, under the mistake effect of external force, misplace easily, and, after some workplace such as the shell to electric component carries out watertight, rotating shaft rotates required revolving force can become big, only turn over the position easily, and need to adjust repeatedly repeatedly just to reach desired position, waste time and energy with the hand rotational positioning.
Summary of the invention:
Technical problem to be solved of the present utility model provides a kind of automatic locking positioning device that is applicable to many gears rotary electric element.
For solving the problems of the technologies described above, the utility model proposes that following technical scheme realizes:
A kind of automatic locking positioning device that is applicable to many gears rotary electric element, it is characterized in that: described automatic locking positioning device mainly is made up of the rotary handle 1 that is fixed on the positioning disc 2 on the electric component shell 5 and radially is located in rotating shaft 4 upper ends, described positioning disc 2 edges have some notches, the center of described positioning disc 2 is provided with the axis hole 23 that cooperates with rotating shaft 4, described rotary handle 1 one ends are provided with back-up ring 11, between back-up ring 11 and rotating shaft 4, be provided with back-moving spring 12, be provided with the alignment pin 13 that matches with described notch at rotary handle 1 other end.
Between positioning disc 2 and rotating shaft 4, be provided with O-ring seals 3.
The utility model brings following beneficial effect: guaranteed the location of many gears, and can not misplace because of bump by mistake, because this device has sealing ring, thereby needing can be used for the occasion of sealing.
Description of drawings:
Fig. 1: the front view of the utility model embodiment
Fig. 2: the utility model embodiment is along the longitudinal sectional view of center line
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Referring to Fig. 1, Fig. 2, rotary handle 1 is located in rotating shaft 4 ends, draw-out handle 1, and back-moving spring 12 is compressed, the also equidirectional former place notch 21 that is drawn out of pin 13, when turning handle 1 to next notch 22, release handle 1, handle 1 resets under the resilience force of back-moving spring 12, pin 13 enters notch 22, finishes the location self-locking.
This device can be used for the location self-locking of many gears rotary electric element, in the occasion of needs sealing, only needs that O-ring seals 3 is set and get final product between positioning disc and rotating shaft.
