Description

Rotate skin chair

Technical field

The present invention relates to a kind of rotation skin chairs.

Background technology

The rotation of existing rotation skin chair is inconvenient to use, and when rotation is obstructed larger, and is easy bad, when rotation is easy to send out different The sound of sample.

Invention content

The purpose of the present invention, which is that, provides a kind of rotation skin chair, and rotation skin chair rotation is steady, has no abnormal sound, and bearing capacity By force.

Technical solution is：A kind of rotation skin chair, including backrest, Double armrest, cushion and chair leg, the cushion lower section are connected with Strong bearing capacity rotates smoothly seat, and chair leg is connected to strong bearing capacity and rotates smoothly under seat.

Preferably, it includes seat and rotating mechanism in support base, rotation that the strong bearing capacity, which rotates smoothly seat, bottom is supported Through-hole is respectively arranged in seat and rotation on seat, rotating mechanism passes through seat in support base and rotation.

Preferably, the support base include square box, 2 arc-shaped types movement items, 2 trapezoidal mobile items, 2 it is flat Row quadrangle moves item and horizontal stripe, 2 arc-shaped type movement items, 2 trapezoidal mobile items, 2 parallelogram movement item settings On square box 57,2 arc-shaped type movement items, 2 trapezoidal mobile items, 2 parallelogram movement item first places are sequentially connected, Horizontal stripe both ends are connected on square box.

Preferably, the length of the diameter and 2 parallelogram movement items every of 2 arc-shaped type movement items every It is equal.

Preferably, the side length of 2 trapezoidal mobile items every moves the wide phase of item every with 2 parallelogram Deng.

Preferably, the included angle of straight line in described 2 arc-shaped type movement every both ends of item and the center of circle is 60 degree.

Preferably, the rotating mechanism include rotary shaft, plane bearing, rolling bearing, stop washer, shaft washer, Round nut and bearing holder (housing, cover), bearing holder (housing, cover) are sleeved on rolling bearing outer surface, and plane bearing is arranged above rolling bearing, rolling bearing It is aligned with plane bearing central hole, rotary shaft is each passed through plane bearing, rolling bearing, horizontal stripe, shaft washer, stop pad Circle, round nut are connected to rotation shaft end.

Preferably, the rolling bearing is deep hook bearing.

Preferably, the rotation shaft length is 20-1 with rotation shaft diameter ratio.

Preferably, the rotation shaft length is 10-15 with rotation shaft diameter ratio.

Compared with prior art, the beneficial effects of the present invention are：

The present invention using when rotation is steady, has no abnormal sound, and bearing capacity is strong.

Description of the drawings

Fig. 1 is overall structure of the present invention；

Fig. 2 is support base structural schematic diagram of the present invention；

Fig. 3 is rotating mechanism decomposition diagram of the present invention.

Specific implementation mode

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 ?.

The present invention will be further described with reference to the accompanying drawings.

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

It includes seat 4 and rotating mechanism 7 in support base 5, rotation, support base 5 and rotation that strong bearing capacity, which rotates smoothly seat, 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 parallel four side of the arc-shaped type movement trapezoidal mobile item 52,2 of item 53,2 of square box 57,2 Shape moves item 51 and the arc-shaped type movement parallelogram of trapezoidal mobile item 52,2 of item 53,2 of horizontal stripe 56,2 moves item 51 It is arranged on square box 57, the 2 arc-shaped type movement parallelogram of trapezoidal mobile item 52,2 of item 53,2 movement items 51 are first Position is sequentially connected, and 56 both ends of horizontal stripe are connected on square box 57.

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

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

Preferably, the included angle of straight line in 1 arc-shaped type movement both ends 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, bearing holder (housing, cover) 76 are sleeved on 77 outer surface of rolling bearing, and plane bearing 72 is 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, which can reach, preferably matches It closes, on the one hand, firmly smaller to achieve the effect that rotation, on the other hand, service life is also longer.It is preferred that rotary shaft 71 is grown 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 present invention rather than limits the present invention's Range, some nonessential modifications and adaptations that those skilled in the art's the above according to the present invention is made belong to this The protection domain of invention.

The present invention expands to any new feature disclosed in the present specification or any new combination, and any disclosed New combination.
