Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment.
As Figure 1-Figure 8, present embodiment provides a kind of handrail rotating mechanism, including fixing axle 1, handrail 2, clamping block
3, stop nut 4, wind spring 5 and locked component 6, handrail 2 offer circular hole 201, the surrounding of 201 side of circular hole in rotation the center point
For an annular groove 202, fixing axle 1 is through in circular hole 201 from the other side of circular hole 201, and clamping block 3 is mounted on annular groove
In 202, stop nut 4 locks clamping block 3, wind spring 5 by the external screw thread on 1 surface of fixing axle from the same side that clamping block 3 is installed
It is set in the outer surface of stop nut 4, the both ends of wind spring 5 are fixed on clamping block 3, and the shaft core position of fixing axle 1 opens up useful
In the blind hole 101 of installation locked component, it is preferred that be provided with locking projections 301 and multiple lock holes 302, wind spring on clamping block 3
5 both ends are respectively set to horizontal end 502 and perpendicular end 501, and horizontal end 502 is inserted into lock hole 302, erect end 501 and hook in locking projections
On 301, due to also adding stop nut 4 between wind spring 5 and clamping block 3, it is used for so being also provided on stop nut 4
Through-hole 401 across the horizontal end 502 of wind spring 5, wherein locked component 6 is mainly made of lock shaft 601 and dead bolt 602,
And lock shaft 601 is also made of inner shaft 603 and outer shaft 604, and the inside of outer shaft 604 and inner shaft 603 is also provided with compressed spring,
It realizes that inner shaft 603 and outer shaft 604 are mutually moved by compressed spring, and is also provided with bolt shallow bore hole on the surface of outer shaft
605, bolt shallow bore hole 605 and dead bolt 602 cooperate, to realize the positioning of lock shaft 601, in order to realize that dead bolt exists
Reciprocating motion in fixing axle 1, the surface of fixing axle 1 offer sliding recess 102, when inner shaft 603 is inserted into blind hole 101, insert
Pin shallow bore hole 605 is to be located in sliding recess 102, and the depth of bolt shallow bore hole 605 cannot too deep or bolt shallow bore hole 605
Along not instead of not straight up and down, there is certain gradient at the position of sliding recess 102, so that dead bolt 602 backhauls
Dynamic, in order to enable locked component 6 is not excessively lofty, the application is also additionally provided with trim 7 in the other end of lock shaft 601, and
