Specific embodiment

All features disclosed in this specification can be with any other than mutually exclusive feature and/or step Mode combines.

Any feature disclosed in this specification unless specifically stated can be equivalent or with similar purpose by other Alternative features are replaced.That is, unless specifically stated, each feature is an example in a series of equivalent or similar characteristics ?.

Below in conjunction with attached drawing, the utility model is described in further detail.

Such as Fig. 1-3, a kind of rotation skin chair, including backrest 1, Double armrest 2, cushion 3 and chair leg 6 are connected with below cushion 3 strong Bearing capacity rotates smoothly seat, and chair leg 6 is connected to strong bearing capacity and rotates smoothly under seat.

It includes support base 5, seat 4 and rotating mechanism 7 in rotation that strong bearing capacity, which rotates smoothly seat, support base 5 and rotation Through-hole 55 is respectively arranged on middle seat 4, rotating mechanism 7 passes through seat 4 in support base 5 and rotation.

Support base 5 includes mobile trapezoidal 52,2 parallel four sides of mobile item of item 53,2 of square box 57,2 arc-shaped types The mobile item 51 of shape and the trapezoidal mobile item 51 of 52,2 parallelogram of mobile item of the mobile item 53,2 of horizontal stripe 56,2 arc-shaped types It is arranged on square box 57, the mobile item 51 of trapezoidal 52,2 parallelogram of mobile item of the mobile item 53,2 of 2 arc-shaped types is first Position is sequentially connected, and 56 both ends of horizontal stripe are connected on square box 57.

Preferably, the diameter of the mobile item of 1 arc-shaped type is equal with the mobile length of item of 1 parallelogram.

Preferably, the side of 1 trapezoidal mobile item is long equal with the mobile width of item of parallelogram.

Preferably, the included angle of straight line in the mobile both ends of 1 arc-shaped type and the center of circle is 60 degree.

Rotating mechanism 7 includes rotary shaft 71, plane bearing 72, rolling bearing 77, stop washer 74, shaft washer 73, circle Nut 75 and bearing holder (housing, cover) 76,76 sets of bearing holder (housing, cover) on 77 outer surface of rolling bearing, plane bearing 72 be arranged on rolling bearing 77 Side, rolling bearing 77 and 72 central hole of plane bearing alignment, rotary shaft 71 be each passed through plane bearing 72, rolling bearing 77, Horizontal stripe 56, shaft washer 73, stop washer 74, round nut 75 are connected to 71 end of rotary shaft.

Rolling bearing 77 is deep hook bearing.

When 71 length of rotary shaft and 71 diameter ratio of rotary shaft are 20-1, bearing capacity and rotary force can achieve and preferably match It closes, on the one hand, firmly can achieve the effect of rotation compared with urine, on the other hand, service life is also longer.It is preferred that rotary shaft 71 is long Degree is 10-15 with 71 diameter ratio of rotary shaft.

It should be understood that the above embodiment that this specification is described in detail is merely to illustrate the utility model rather than limits this reality With novel range, some nonessential improvement that those skilled in the art's above content according to the present utility model is made and Adjustment belongs to the protection scope of the utility model.

The utility model expands to any new feature disclosed in the present specification or any new combination, and disclose Any new combination.
