The specific embodiment

A kind of rotary seat of the utility model comprises seat support, chair seat frame, pedestal, it is characterized in that: bottom one side of said chair seat frame is connected with chair seat frame through rotating mechanism.

To shown in Figure 5, a kind of turning chair of present embodiment comprises seat support 1, chair seat frame 2 and is located at the pedestal 3 at one lateral edges place, chair seat frame bottom like Fig. 1; Seat support in the present embodiment comprise backrest with can with the folding cushion of backrest, cushion can move between folding position and use location, this seat support is folding chair; Be provided with rotating mechanism and detent mechanism between pedestal 3 and the chair seat frame 2; The middle part of being located at the handle 24 of chair seat frame one side is connected with chair seat frame 2 through rotating shaft 26, can 26 rotate to an angle around the shaft.The chair seat frame of handle 24 1 ends below is provided with limit shaft 27, and the other end and fix shaft 23 are hinged.

Rotating mechanism comprises the reaction plate 31 of being located at pedestal and is located at chair seat frame and the rotating disk of reaction plate corresponding position 21.Rotation axis hole 32 in the middle of the reaction plate 31.Corresponding rotation axis hole position is provided with the S. A. 22 of protrusion on the rotating disk 21, and S. A. 22 cross sections are circular, and S. A. 22 inserts can cooperatively interact in the rotation axis hole 32 and also can rotate around central axis, makes reaction plate 31 and rotating disk 21 rotate relatively.

Detent mechanism comprises on the reaction plate 31 around rotation axis hole bung three positioning grooves 33 on a round track is set.The angle that positioning groove is 33 can be set according to the reservation needs, can be made as miter angle.Cross-sectional plane is also other shape of circle.Detent mechanism also comprises a fix shaft 23 of rotating disk 2 corresponding positioning groove positions protrusion; The shape of fix shaft 23 matches with positioning groove 33; Rotating disk 21 forwards to when subscribing the position, and fix shaft 23 can insert in the positioning groove 33 and cooperatively interact, and makes rotating disk 21 and reaction plate 31 fix in the X-Y direction.As shown in Figure 7, S. A. 22 inserts in the rotation axis hole 32, and installs through the bearing 4 and the hole wall matching and fixing of rotation axis hole 32, but can rotate relatively.S. A. 22 ends of bearing 4 belows are connected with the nut 5 that can prevent that S. A. 22 and bearing from getting loose, and the locating ring 6 that is used to prevent nut 5 loosening landings, thereby make S. A. 22 and rotation axis hole 32 fixing on Z-direction.As shown in Figure 6, an end of fix shaft 23 upper ends and handle 24 is hinged, and its stage casing outer wall is with a retracing spring 28 simultaneously, and the outside is socket one axle sleeve 29 again.The axle sleeve bottom is affixed with rotating disk 21.Retracing spring 28 lower ends and fix shaft 23 end flange are conflicted, and conflict in upper end and axle sleeve 29 tops.Instantly the other end of pressure handle hand 24, fix shaft 23 is driven to move up synchronously, its lower end retraction rotating disk 21 and compression reseting spring 28; Can apply power rotary turnplate 21 this moment, i.e. rotary seat is when to rotating to the desired location; Unclamp handle 24; Retracing spring 28 resets fix shaft 23 simultaneously, and its lower end is stretched out rotating disk 21 again and headed in the positioning groove 33 and cooperates, and then can realize the location.

Detent mechanism also comprises the arc notch 34 that reaction plate 31 is provided with along edge week place, and the radian of arc notch 34 is a bit larger tham or equals three maximum angle number of degrees between the positioning groove 33.Corresponding arc notch 34 places are provided with an angle axle 25 on the rotating disk 21.During rotating disk 21 rotations, angle axle 25 moves along camber line in arc notch 34, can prevent that the dial rotation angle is excessive, and can accurately locate, and fix shaft 23 is inserted in the positioning groove 33 rapidly and accurately.
