This, the prior art is there is installation trouble and has the problem of security risk.
Utility model content
The purpose of the utility model is to provide a kind of rotational structures of chair.The utility model have facilitate installation and
The characteristics of can be improved safety in utilization.
The technical solution of the utility model includes: the rotational structure of chair, including fixing seat, fixing seat top are equipped with rotating seat；
The fixing seat includes pedestal, and the fixing groove matched with support plate is equipped with below pedestal, circular trough, circle are equipped with above pedestal
Shape slot inner wall is equipped with annular slot, and circular trough bottom is equipped with multiple mounting holes being circular layout, is successively arranged bullet in mounting hole
Spring and detent ball.
In the rotational structure of chair above-mentioned, the rotating seat includes the rotating cylindrical matched with circular trough, rotation
Cylindrical base is equipped with location hole corresponding with mounting hole, is equipped with mounting plate above rotating cylindrical；The rotating cylindrical outer wall is set
There are two the raised lines being arranged symmetrically, and raised line is matched with annular slot.
In the rotational structure of chair above-mentioned, it is equipped with telescopic rod between the raised line inner wall and rotating cylindrical outer wall, stretches
Compressed spring is arranged on contracting bar；The ring rib outer wall is equipped with idler wheel.
In the rotational structure of chair above-mentioned, the fixing groove is equipped with threaded hole.
Compared with prior art, the utility model replaces traditional rotary shaft by setting rotation stool surface, effectively mentions
The high security performance of rotation, while being also convenient for installing.By the way that fixing groove is arranged in pedestal bottom, to be matched with support plate,
Not only facilitate installation, but also the precision of installation can be improved, moreover it is possible to guarantee the stability used；By the way that spring is arranged in fixing seat and determines
Location hole is arranged in rotating seat bottom in position ball, and the two is combined, can be positioned to rotary course, to control rotation
Speed, improve security performance.By the way that telescopic rod and compressed spring are arranged between raised line and rotating cylindrical, be both easily installed and
Disassembly, and buffering can be played the role of, guarantee being normally carried out for rotation.In conclusion the utility model, which has, facilitates installation
The characteristics of with can be improved safety in utilization.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.The rotational structure of chair is constituted as shown in Figure 1 to Figure 3, and the rotation stool surface 3 includes fixing seat 301,
Rotating seat 302 is equipped with above fixing seat 301；The fixing seat 301 includes pedestal 303, is equipped with below pedestal 303 and support plate
6 fixing grooves 304 matched, circular trough 305 is equipped with above pedestal 303, and 305 inner wall of circular trough is equipped with annular slot 306, circle
305 bottom of shape slot is equipped with multiple mounting holes 307 being circular layout, and is successively arranged spring 308 and detent ball in mounting hole 307
309。
The rotating seat 302 includes the rotating cylindrical 311 matched with circular trough 305, and 311 bottom of rotating cylindrical is equipped with
Location hole 312 corresponding with mounting hole 307 is equipped with mounting plate 313 above rotating cylindrical 311；311 outer wall of rotating cylindrical
If there are two the raised lines 314 being arranged symmetrically, and raised line 314 is matched with annular slot 306.
It is equipped with telescopic rod 315 between 311 outer wall of 314 inner wall of raised line and rotating cylindrical, is arranged on telescopic rod 315
Compressed spring 316；314 outer wall of ring rib is equipped with idler wheel 317.
The fixing groove 304 is equipped with threaded hole 310.
The course of work of the utility model: by manual compression raised line and idler wheel, so that rotating cylindrical enters in circular trough,
After idler wheel reaches annular slot, extend under spring force, idler wheel is in contact with annular slot, mounting hole and location hole phase
Matching, is positioned by detent ball.In rotary course, rotating seat is rotated, idler wheel is moved along annular slot, meanwhile,
The lower end surface of rotating cylindrical is in contact with detent ball, compression set ball, so that detent ball driving compressed spring is shunk, when
After next location hole occurs, detent ball resets under spring force, realizes positioning and limit.
