Description

The lifting rotating disc

Technical field

The utility model relates to the mechanism in a kind of lowering or hoisting gear, the rotating disc in especially a kind of lifting.

Background technology

General chair all is fixed, and the direction of seat is fixed, and needs the moving occasion of not stall just not too suitable at some, as such as in the bar, operates the place of multiple computers, all needs a kind of revolvable seat.

Now some seat can lifting, also can rotate, such as a kind of computer chair of rotation, but this whirligig is the rotation by the lifting cylinder to be realized, in rotation, wearing and tearing can be more serious, and after the rotation, the stressed of lifting cylinder changes, and occurs danger such as detonation easily.

Patent Office of the People's Republic of China's Handling device that to have announced a CN2677357Y patent name be rotatable lifting on February 9th, 2005, comprise base, be installed on elevating mechanism and support platform on the base, also have a rotatable bearing platform to be installed on the support platform, rotatable bearing platform is installed on the support platform by a rotating shaft, and a motor is connected on the rotating shaft by transmission mechanism.Have only a rotating shaft between bearing platform and the support platform, stability of strutting system is bad, tilts easily.

Patent Office of the People's Republic of China discloses a CN101538950A document on September 23rd, 2009, name is called lifting turntable, comprise vehicle-containing location-plate and base, also comprise interconnective rotary unit and lifting unit, rotary unit comprises top rotary table, lower rotary table, the rotating disk reducing motor that distributes from top to bottom, be in transmission connection between top rotary table and the lower rotary table, the rotating disk reducing motor is connected with lower rotary table to drive the lower rotary table rotation.The catching plate structure more complicated of this structure, fault rate is than higher.

Above-mentioned two kinds rotating disk is by electronic mode, and cost is higher.

Summary of the invention

The utility model has solved prior art turntable complex structure, and the shortcoming that fault rate is higher provides a kind of simple in structure, the lifting rotating disc that fault rate is lower.

The utility model has also solved the electronic mode of available technology adopting, and the shortcoming that cost is higher provides a kind of simple in structure, lower-cost lifting rotating disc.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of lifting rotating disc, comprise top rotary table and lower rotary table, top rotary table has a lug boss, has a lug boss on the lower rotary table, the lug boss butt joint was provided with plane bearing between top rotary table and the lower rotary table when top rotary table was connected with lower rotary table.Lower rotary table is fixed on the elevating bracket, the relative lower rotary table of top rotary table rotates, and passes through lug boss butt joint separately when top rotary table is connected with lower rotary table, and lug boss has bigger area, after both contacts, Area of bearing is big, and supporting ﹠ stablizing connects by plane bearing, reduced rotational resistance, the anglec of rotation is also unrestricted, and overall structure is fairly simple, and cost is lower.

As preferably, top rotary table is that stainless steel integrated punching press forms circular configuration, and the centre is a lug boss, and periphery is the plane; Lower rotary table is that stainless steel integrated punching press forms square structure, the middle upper lug boss that is changed in limit partially, and periphery is the plane.Integral body is stamped to form, and is easy to make, the lug boss butt joint, and the plane of periphery just can not contact the resistance that reduces to rotate.

As preferably, be circular hole in the middle of the lug boss of top rotary table, be the circle ring column of turnover in the middle of the lug boss of lower rotary table, the diameter of circle ring column is less than the diameter of circular hole, and circle ring column extend in the circular hole when top rotary table was connected with lower rotary table; Plane bearing is nested with outside the circle ring column, and the Lower Half of plane bearing is outside the lug boss of lower rotary table, and the first half of plane bearing is in the lug boss of top rotary table.Circle ring column extend in the circular hole, plays positioning action, and plane bearing is nested with on circle ring column, has improved connection stability.

As preferably, the peripheral plane of lower rotary table is provided with the reinforcement of projection.The reinforcement at lower rotary table place can prevent that the excessive lower rotary table that makes of weight from deforming.

The beneficial effects of the utility model are: top rotary table is connected by plane bearing with lower rotary table, and lug boss separately is staggered relatively, has increased Area of bearing, improves connection stability.
