Abstract
The utility model discloses an improved table and chair rotating mechanism, which comprises a supporting bracket, a rotating bracket, rolling balls and a rotating shaft, wherein the rotating bracket is fixedly sheathed on the rotating shaft, a fixed shim for rolling balls is arranged between the supporting bracket and the rotating bracket, and the shim is provided with a circle of circular holes; the positions corresponding to the circular holes on the supporting bracket and the rotating bracket are respectively provided with a circle of annular grooves, the cross sections of which are in a hemisphere shape and the rolling balls are sheathed in the circular holes and arranged in the annular grooves. By the arrangement of the fixed shim for rolling balls, the distance between every two rolling balls is kept constant and thus contact collisions can not occur so as to avoid ruptures resulting from collisions and reduce noises generated from mutual collisions when the utility model rotates. The utility model decreases the used amount of rolling balls and reduces cost, and the improved table and chair rotating mechanism can keep stable and safe when the utility model rotates.
Description
Technical field
The utility model relates to the rotating mechanism of rotary tables and chairs.
Background technology
Existing rotary table, chair often adopt the ball-type rotating mechanism.This rotating mechanism is that the contact-making surface at fixture and revolving part (as rotation supporting plate or rotating disk etc.) is provided with a circle ball, when rotating revolving part, relies on the rolling of ball that revolving part is rotated.When rolling, collide extruding owing to roll mutually, produce bigger noise, and break easily.Fragment after breaking is retained in the gap, easy to clean not, and influence the running of mechanism.Because indivedual balls break, lack, imbalance when causing dial rotation.
Summary of the invention
The purpose of this utility model is to provide a kind of rotating mechanism that can reduce noise, improve the degree of balance, stable rotation tables and chairs safe in utilization.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of improved tables and chairs rotating mechanism, comprise frame support bracket, rotary bracket, ball and rotating shaft, rotary bracket is fixedly sleeved in rotating shaft, it is characterized in that: be installed on a ball setting-up piece between described frame support bracket and the rotary bracket, offer a circle circular hole on the pad; Described frame support bracket and rotary bracket are hemispheric annular groove corresponding to respectively offering a circle cross section on the position of described circular hole, and described ball is sheathed on described circular hole, and installs in groove.
Specifically, described rotary bracket, frame support bracket and rotating shaft are connected and installed by a flat thrust ball bearing, and circle is fixedly installed in described frame support bracket on the bearing, and snare is connected in the described rotating shaft under the bearing.
The utility model is provided with the ball setting-up piece between rotary bracket and frame support bracket, ball rolls in each hole of ball setting-up piece, therefore ball keeps constant space each other, can not come in contact collision, avoided colliding breaking of causing, collided the noise of generation when having reduced rotation mutually.The setting of ball setting-up piece has reduced the use amount of ball, has reduced cost.The setting of ball setting-up piece makes and is keeping fixing distance between rotary bracket and the frame support bracket, even accidental indivedual ball breaks, lacks the balance that also can not influence rotary bracket, makes mechanism held stationary, safety when rotated.
Description of drawings
Fig. 1 is the generalized section that rotating mechanism of the present utility model is fixed in pedestal.
Fig. 2 is a ball setting-up piece schematic diagram.
The specific embodiment
As shown in Figure 1,1 is rotating shaft, and 2 is rotary bracket, and 3 is the ball setting-up piece, and 4 is frame support bracket, and 5 is ball, and 6 is bearing, and 7 is pedestal.
Rotary bracket 2 is installed in supporting splint 4 tops, is lined with ball setting-up piece 3 between the two.Ball setting-up piece 3 structures are annular gaskets that offers a circle circular hole 31 as shown in Figure 2.Corresponding to the position of circular hole 31, respectively offer a ring annular groove on the bottom surface of rotary bracket 2 and frame support bracket 4, the cross section of groove is hemispherical.
Rotary bracket 2, frame support bracket 4 and rotating shaft 1 are connected and installed by flat thrust ball bearing.The circle 61 of going up of bearing is fixedly installed in frame support bracket 4.Frame support bracket 4 is fixed on the pedestal 7 by fixed mechanism.Following circle 62 sockets of bearing are installed on rotating shaft 1.Rotating shaft 1 two ends outwards bend chucking fixedly rotary bracket 2 and bearing 6.Rotary bracket 2 is socketed in the rotating shaft 1.The circle 61 of going up of bearing 6 maintains static, and following circle 62 rotates with rotating shaft 1, and rotary bracket 2 also rotates with rotating shaft 1.
