When seat rotates, seat support is rotated resetting block and rotates simultaneously, and now bearing A rotates on the upper surface of spinning reduction block,
Owing to the end face of rotating restoring device exists a difference in height, and bearing is in the upper surface of spinning reduction block when initial position
Lowest part, therefore the rotation of seat support will necessarily make the decrement of the compression spring between spinning reduction block and locating part become
Changing, after externally applied forces is cancelled, the power lifting spinning reduction block of compression spring deformation makes bearing A be returned to spinning reduction block
The lowest part of upper surface, now seat support is just returning again.And by the side making bearing A rotate on the inclined-plane of spinning reduction block
Formula makes compression spring be compressed, the rotational angle of seat support in 0-180 degree and two intervals of 180-360 degree, the decrement of spring
Respectively corresponding, can ensure that seat support in the slewing area of 360 degree and the multiple of 360 degree, seat support all can just return.
The lower section of seat support is provided with installation cavity A, and the medial wall of installation cavity A is provided with axially disposed rib A, described connection
Part is provided with installation cavity B, and the lateral wall of installation cavity B is provided with the muscle groove A coordinated with described rib A, and the medial wall of installation cavity B sets
Having axially disposed muscle groove B, the lateral wall of spinning reduction block is provided with the rib B coordinated with described muscle groove B.By muscle groove and
The mode that rib coordinates connects seat support and spinning reduction block, limits and relatively rotates between three, simple in construction, and rotates multiple
The motion on vertical direction is may occur in which between position block and connector.
As preferably, described locating part is arranged on bearing axle by bearing B, and the lateral wall of locating part is provided with described
The rib C that muscle groove B coordinates, described spinning reduction block, bearing A, bearing are fixed axle, compression spring, bearing B and locating part and are positioned at peace
Behaveing affectedly in B, connector is positioned in installation cavity A.Locating part is coordinated by rib C and muscle groove B and is connected with connector, and locating part leads to
Cross bearing to install so that frictional force when seat support band follower link rotates reduces.
As preferably, coordinated fixing between bearing axle with chair foot by Morse's taper.By cone between bearing axle and chair foot
Degree coordinates fixing.
As preferably, coordinated fixing between bearing axle with chair foot by Morse's taper.Make the easy to assembly of this device.
As preferably, described chair foot is four star feet, and four star feet are provided with callosity.
The spinning reduction mechanism of the swivel chair of said structure, has the advantages that 1, is oblique by bearing A, upper surface
The spinning reduction block in face and compression spring realize resetting, simple in construction.2, it is flexibly connected between spinning reduction block with bearing axle,
Spinning reduction block is connected with seat support by connector, and seat support can realize rotating at any angle.

Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiment of this patent is described in further detail.
The spinning reduction mechanism of a kind of swivel chair as Figure 1-Figure 4, including seat support 1, bearing axle 9 and chair foot 11.Seat support 1
Upper end level, be used for installing seat, it is column that the bottom of seat support 1 is provided with installation cavity A, installation cavity A, the medial wall of installation cavity A
Circumference on be distributed many and have axially disposed rib A.Coordinated fixing between bearing axle 9 with chair foot 11 by Morse's taper,
Between bearing axle 9 and chair foot 11 fixed.The chair foot 11 of the present embodiment selects four star feet, and chair foot 11 is provided with callosity 12.
Spinning reduction block 3, compression spring 6 and locating part 7 it is sequentially installed with from top to bottom on bearing axle 9.Can be around bearing axle 9
The spinning reduction block 3 rotated is actively socketed on bearing axle 9, and spinning reduction block 3 is the class cylinder that upper surface is inclined-plane, rotates
The lateral wall of resetting block 3 is provided with rib B.The top of bearing axle 9 is provided with axis hole, can rotate along the end face of spinning reduction block 3
Bearing A4 fixes axle 5 by bearing and is fixed on described bearing axle 9, and initial position and seat support 1 towards dead ahead time, bearing A4
It is positioned at the lowest part of spinning reduction block 3 upper surface.Locating part 7 is fixed on the bottom of bearing axle 9 by bearing B, outside locating part 7
Side is provided with rib C.Compression spring 6 is compressed between spinning reduction block 3 and locating part 7.
Spinning reduction block 3 is connected with seat support 1 by connector 2, and connector 2 is provided with installation cavity B, the lateral wall of installation cavity B
Being provided with muscle groove A, the medial wall of installation cavity B is provided with muscle groove B, spacing with rib B by muscle groove B between connector 2 and seat support 1
Closely cooperating, can not relatively rotate between connector 2 and seat support 1, muscle groove B and rib B coordinates restriction spinning reduction block 3 and connector
Relatively rotate between 2, but the relative slip on vertical direction can occur between spinning reduction block 3 with connector 2.Limit
Position part 2 is positioned at the downside in installation cavity B, and rib C and muscle groove B coordinates relatively rotating between restriction locating part and connector.
The equal position of axle 5 fixed by the bearing B8 of this device, locating part 7, compression spring 6, spinning reduction block 3, bearing A4 and bearing
In the installation cavity B of connector 1, connector 1 is positioned in the installation cavity A of seat support 1.A part for installation cavity A sidewall is positioned at chair foot
In 11, do not fix between chair foot 11 and base 1, and the coupling part between seat support 1 and chair foot 11 is provided with plastic sleeve 10.
