SUMMERY OF THE UTILITY MODEL
In order to realize the functions of stable and flexible adjustment of lever transmission, the utility model adopts the following technical scheme:
a vertical lifting mechanism comprises a synchronizing wheel, a driving device, a steel belt, a central shaft, a transmission arm and a rotating shaft; the synchronous wheel is connected with a driving device, and the driving device drives the synchronous wheel to rotate; one end of the steel belt is wound on the synchronizing wheel, the other end of the steel belt is fixedly connected with one end of the transmission arm, the rotating shaft transversely penetrates through the other end of the transmission arm, and the transmission arm rotates around the rotating shaft; the transmission arm is provided with a cavity, a connecting rod is transversely arranged in the cavity, a rotating bearing is fixedly mounted on the connecting rod, and the bottom end of the central shaft is connected with the bottom of the rotating bearing. Through swivel bearing and the bottom of the central shaft, the bearing can rotate, the direct contact between the rotating arm and the bottom surface of the central shaft is avoided, and the abrasion between the rotating arm and the central shaft caused by long-time rotation is reduced. In addition, this vertical lift mechanism passes through the steel band and drives the transmission arm promotion, and the transmission arm is the jacking center pin again, realizes the function of jacking, replaces the rigid member lever spare among the traditional lever mechanism into flexible member lever like this, when guaranteeing that rigid mechanism is stable, utilizes the flexibility of flexible member, nimble adjustment mechanism's transmission distance.
The bearing assembly comprises a shell, a groove is formed in the shell, two bearings are arranged on the inner wall of the shell and located on the same straight line, a transmission arm is arranged in the groove, and the two bearings are connected with a rotating shaft respectively.
Specifically, the shell is provided with a limiting groove, and one end of the transmission arm, which is connected with the steel belt, penetrates through the limiting groove. The transmission arm can be limited to move in a certain height through the limiting groove, and the situation that the steel belt drives the transmission arm to be too high in lifting and damage is caused to the central shaft in the lifting process is avoided.
Specifically, the driving device is a speed reduction motor.
In summary, the apparatus of the present invention has the following advantages: the mechanism replaces a rigid member lever piece in the traditional lever mechanism with a flexible member lever, and utilizes the flexibility of the flexible member to flexibly adjust the transmission distance of the mechanism while ensuring the stability of the rigid mechanism.

Detailed Description
The present invention is further described below with reference to fig. 1 to 3.
A vertical lifting mechanism comprises a synchronizing wheel 1, a driving device, a steel belt 7, a central shaft 2, a transmission arm 4 and a rotating shaft 5; the synchronizing wheel 1 is connected with a driving device, the driving device drives the synchronizing wheel 1 to rotate, and the driving device is a speed reducing motor.
One end of the steel belt is wound on the synchronizing wheel 1, the other end of the steel belt is fixedly connected with one end of the transmission arm 4, the rotating shaft 5 transversely penetrates through the other end of the transmission arm 4, and the transmission arm 4 rotates around the rotating shaft 5; the transmission arm 4 is provided with a cavity 11, the cavity 11 is internally and transversely provided with a connecting rod 8, the connecting rod 8 is fixedly provided with a rotating bearing 6, and the bottom end of the central shaft 2 is contacted with the rotating bearing 6. Connect through bearing and center pin 2 end, bearing self is rotatable, avoids the rotor arm direct and 2 bottom surfaces direct contact of center pin, reduces to rotate for a long time the back cause with the center pin 2 between the wearing and tearing. In addition, this vertical lift mechanism drives transmission arm 4 through steel band 7 and promotes, and transmission arm 4 is jacking center pin 2 again, realizes the function of jacking, replaces the rigid member lever spare among the traditional lever mechanism into flexible member lever like this, when guaranteeing that rigid mechanism is stable, utilizes the flexibility of flexible member, nimble adjustment mechanism's transmission distance.
In order to protect the transmission arm 4 from the influence of the external environment, and to support the fixed support for the transmission arm 4, the housing 3 is further provided, the groove 9 is formed in the housing 3, two bearings are arranged on the inner wall of the groove 9 and located on the same straight line, the transmission arm 4 is arranged in the groove 9, and the two bearings are respectively connected with the rotating shaft 5. The housing 3 may be fixedly mounted with an external platform. In order to limit the transmission arm 4 to move in a certain height, the steel belt is prevented from driving the transmission arm 4 to be lifted too high and damage the central shaft 2 in the lifting process, so that the shell 3 is provided with the limiting groove 10, and one end of the transmission arm 4, which is connected with the steel belt, penetrates through the limiting groove 10.
In summary, the apparatus of the present invention has the following advantages: the mechanism replaces a rigid member lever piece in the traditional lever mechanism with a flexible member lever, and utilizes the flexibility of the flexible member to flexibly adjust the transmission distance of the mechanism while ensuring the stability of the rigid mechanism.
