Example 2:

referring to fig. 1 to 12, on the basis of the lifting frame body of embodiment 1, the lifting frame body of the present embodiment has the same general structure as that of the lifting frame body of embodiment 1, except that a torsion spring 32 is disposed between the inner wall of the motor casing cover 31 and the helical gear 24, and the torsion spring 32 is filled in a gap between the upper end of the helical gear 24 and the inner wall of the motor casing cover 31.

Because the cabinet body 35 has a certain dead weight, and after the cabinet body 35 stores a certain weight of articles, the cabinet body can generate a certain gravity action on the lifting driving mechanism of the lifting frame body, and at the moment, the influence on the service life and the service state of the lifting driving mechanism, which is possibly caused by overcoming the weight of the cabinet body 35, needs to be considered for the lifting driving mechanism.

For daily use, the cabinet 35 is raised or lowered within 10 seconds, the length of the push rod is 600mm, and the speed is estimated to be 60 mm/s. To achieve this speed, only the motor speed is increased or the lead of the lead screw 16 is increased.

The rotating speed of the motor is increased, and the purpose of increasing the speed can be achieved. But the problem of noise caused by the noise cannot be solved (the problem exists in the linear driving industry all the time). Therefore, the lead of the screw rod 16 is increased, and the problem of weakening self-locking force caused by increasing the lead of the screw rod 16 is generally solved in the industry. The lifting driving mechanism of the embodiment is always loaded in the axial direction of the screw rod 16, and the self-locking force is reduced to bring about the automatic sinking of the cabinet body 35, which is a problem to be avoided for the lifting cabinet. So, under the action of gravity of the cabinet body 35, in time when driving motor 27 is in quiescent condition, screw 17 and slip table 18 subside downwards under the influence of the gravity of the cabinet body 35, screw 17 descends and can drive lead screw 16 to rotate, lead screw 16 and helical gear 24 lug connection, helical gear 24 follows the rotation, helical gear 24 rotates and drives out axle worm 25 rotatory, generally speaking, in this stage, direct current motor can compare in the better auto-lock performance of alternating current motor because of the existence of permanent magnet, when the auto-lock power of motor is greater than the revolving force that worm 25 brought because of slip table 18 subsides, the phenomenon that slip table 18 subsides can not take place this moment. However, as the lead is increased, the sinking force of the sliding table 18 is increased, the rotating force of the connecting screw rod 16 and the helical gear 24 is increased, so that the rotating force of the worm 25 is increased, and when the rotating force at the worm 25 is larger than the self-locking force of the motor, the whole lifting driving mechanism moves in the opposite direction to the rated direction.

In view of the above, the present embodiment is provided with a torsion spring 32 between the inner wall of the motor housing cover 31 and the helical gear 24, and the torsion spring 32 is filled in the gap between the upper end of the helical gear 24 and the inner wall of the motor housing cover 31. Specifically, the torsion spring 32 adopted in this embodiment includes an annular body 321, and a first convex tooth 322 and a second convex tooth 323 which are arranged at two ends of the annular body 321 in the axial direction; the first convex teeth 322 are used for connecting with the inner wall of the motor casing cover 31; the second spur 323 is for coupling with the helical gear 24.

When the driving motor 27 is operating normally, i.e. the helical gear 24 is operating normally, the annular body 321 of the torsion spring 32 near the second protruding tooth 323 is partially contracted, the radial dimension of the whole torsion spring 32 is reduced, the friction force between the torsion spring 32 and the motor housing 31 is reduced, and the normal rotation force of the motor is not greatly influenced. When the weight of the cabinet 35 borne by the nut 17 is large, the cabinet 35 makes the nut 17 move downward relative to the screw rod 16, at this time, the screw rod 16 will rotate relative to the nut 17, because the screw rod 16 is connected with the helical gear 24, the helical gear 24 rotates along with the screw rod 16, so that the part of the whole torsion spring 32 near the second convex tooth 323 is opened, and the first convex tooth 322 will not rotate with the second convex tooth 323 due to the existence of friction force, at this time, the whole torsion spring 32 is in an opened state, and the friction force with the motor housing cover 31 is increased. The frictional force can effectively offset the rotating force caused by the falling of the cabinet body 35 under the action of gravity, thereby improving the use stability of the integral lifting driving mechanism.
