In view of this, the purpose of this utility model is to provide a kind of knob, to solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
A kind of knob, wherein, including ladder main shaft, the first limited block, the second limited block, elastic spacing block, spill spin block,
Back-up ring, elastomeric element, Magnet and banking stop, described Magnet is fixed on bottom described ladder main shaft, and described ladder main shaft is by upper
Having groove, the first ladder, the second ladder and the 3rd ladder under to, described first limited block has the first locating notch and overlaps
Being located on described ladder main shaft and be positioned on described first ladder, described elastic spacing block is sheathed on described ladder main shaft also
Being positioned on described second ladder, described spill spin block is boss structure and is sheathed on described ladder main shaft and is positioned described
On three ladders, described second limited block has the second locating notch and is sheathed on described elastic spacing block and bottom and described rotation
Switch block screw top connects, and described elastomeric element is located in described elastic spacing block, the second ladder of described ladder main shaft and the
Having the 3rd locating notch between three ladders, described banking stop has the 4th locating notch and is sheathed in described groove, described
First locating notch, described second locating notch, described 3rd locating notch and described 4th locating notch towards same direction,
Described shield ring sleeve is located at bottom described second limited block and is carried on the boss structure of described spill spin block.
Above-mentioned knob, wherein, described elastomeric element is spring.
Compared with the prior art, the beneficial effects of the utility model are:
Reduce the external forces impact on the mandrel of encoder, improve the job stability of encoder.
