The utility model content
The purpose of the utility model is to design a kind of later-model rotary positioning mechanism, addresses the above problem.
To achieve these goals, the technical scheme of the utility model employing is following:
A kind of rotary positioning mechanism; Comprise upper base plate, following seat board, central rotating shaft, bearing and registration device; Said upper base plate and said seat board down are oppositely arranged up and down; Said bearing embeds in the said seat board down, and the bottom of said central rotating shaft is stretched in the said bearing and with said bearing and matched, and the top of said central rotating shaft is fixed on the said upper base plate; Said registration device comprises fixed muffle, set pin, spring and backguy up and down, and said fixed muffle is fixed on the said upper base plate, and said spring and said set pin up and down are arranged in the said fixed muffle, and said spring withstands on the said set pin up and down; One end of said backguy connects said set pin up and down, and the other end stretches out said fixed muffle; Said seat board down is provided with at least one fixed orifice that matches with said set pin up and down.
Also comprise nylon cushion, be relatively set with low groove on said upper base plate and the following seat board, said going up between the low groove is provided with groove cavities, and said nylon cushion is arranged in the said groove cavities.
Said backguy is a steel rope.
Said fixed muffle is fixed on the said upper base plate through screw thread.
When said fixed orifice during more than or equal to two, said fixed orifice axis around said central rotating shaft on said seat board down is uniformly distributed with into a week.
Said fixed orifice is 24.
Task of the present invention provides simple, the easy to operate rotating mechanism of a kind of mechanism.This rotating mechanism structure is as shown in the figure.Whole rotary positioning mechanism is divided into 1 upper base plate, 2 nylon cushions, 3 times seat boards, 4 central rotating shafts, 5 springs, 6 steel ropes, 7 fixed muffles, part such as set pin, 9 bearings is formed about in the of 8.Upper base plate 1 and cushion frame seat surface plate etc. are connected, and the chair leg of following seat board 3 and seat etc. is connected, and bearing 9 embeds down in the seat boards 3; Lubricate when nylon jacket 2 is rotated at seat, central rotating shaft 4 is connected with upper base plate 1 through bolt, and fixed muffle 7 is to be threaded with upper base plate 1; Spring 5 is stuck in the fixed muffle 7; Set pin 8 moved up about steel rope 6 drove, and spring 5 was compressed, after upper base plate 1 rotates to selected position; Unclamp steel rope 6, set pin 8 was got back to down in the knock hole of seat board 3 about the application force of spring 5 made.Following seat board has 24 knock holees, and per 15 ° of adjustings once.The present invention can satisfy the static strength requirement of seat again when satisfying the seat spinfunction.Solved the fugitiveness of rotary seat.
The beneficial effect of the utility model can be summed up as follows:
1, the utility model can satisfy the static strength requirement of seat again when satisfying the seat spinfunction, solved the instability problem of rotary seat of the prior art.
2, the utility model is simple in structure, low production cost.
Description of drawings
