Detailed Description

The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.

Example (b): an electric lifting table is shown in figure 1 and comprises a table top 4, wherein a plurality of table legs 1 are arranged at the lower end of the table top 4, a motor 6 is arranged at the lower end of the table top 4, a cross rod 12 is connected between two table legs 1 at the same side, a placing plate 5 is connected between the two cross rods 12, the motor 6 is arranged on the placing plate 5, and an output shaft of the motor 6 is connected with a threaded rod 8; the novel table leg structure is characterized in that the table leg 1 is sleeved with a sliding sleeve 2, the inner wall of the sliding sleeve 2 is not in contact with the side wall of the table leg 1, the sliding sleeve 2 and the side wall of the table leg 1 can be prevented from being damaged due to long-time mutual friction, a connecting plate 11 is connected between two sliding sleeves 2 at the same side, a moving plate 10 is connected between two connecting plates 11, and a threaded sleeve 7 in threaded connection with a threaded rod 8 is embedded in the moving plate 10; the upper surface of the connecting plate 11 is provided with a supporting rod 9, and the upper end of the supporting rod 9 is connected with the lower surface of the table top 4.

The side wall of the table leg 1 is provided with a plurality of guide grooves 3, as shown in figure 2, the inner wall of the sliding sleeve 2 is provided with a plurality of grooves 13, the grooves 13 are internally provided with balls 14, the caliber of the notch of each groove 13 is smaller than the maximum diameter of each ball 14, the widest part of each ball 14 is positioned in each groove 13, namely, more than half of each ball 14 is positioned in each groove 13, only the small part of each ball is exposed out of each groove 13 to ensure that each ball 14 cannot fall out of each groove 13, each ball 14 is positioned in the corresponding guide groove 3 and is attached to the inner wall of each guide groove 3 to ensure that the sliding sleeve 2 can only move up and down along the guide groove 3, so that the table top 4 can only move up and down to improve the stability of the table top 4 when moving, the length of each guide groove 3 is larger than that of the threaded rod 8, the inner wall of each guide groove 3 is provided with an arc surface which can enable each ball 14 to be attached to the inner wall of each groove 13, the situation that the ball 14 slips in the groove 13 is prevented, and the ball 14 can roll in the groove 13 smoothly.

The working principle is as follows: when the height of desktop 4 needs to be adjusted, only need starter motor 6, motor 6's output shaft drives threaded rod 8 and rotates, because thread bush 7 inlays and establishes on movable plate 10, and movable plate 10 is connected with sliding sleeve 2 through connecting plate 11 for thread bush 7 only can reciprocate, can't rotate along with threaded rod 8's rotation, thread bush 7 reciprocates and can drive movable plate 10 and connecting plate 11 and reciprocate, and then drives bracing piece 9 and reciprocate, finally drives desktop 4 and reciprocates, thereby realizes the regulation to desktop 4 height.

When the connecting plate 11 reciprocated, can drive corresponding sliding sleeve 2 and reciprocate for ball 14 rolls from top to bottom in guide way 13, can enough play the effect of direction, can be changed into the rolling friction between ball 14 and the guide way 13 with the sliding friction between sliding sleeve 2 and the table leg 1 again, has reduced frictional force, makes desktop 4 reciprocate more stably.

Furthermore, when the lifting table needs to be lubricated and maintained, only lubricating oil needs to be smeared on the guide groove 13, the operation is simple and convenient, and for the lifting table made of a metal material, even if the inner wall of the sliding sleeve 2 rusts due to air oxidation in long-time use, the sliding sleeve 2 is not in contact with the table legs 1, the phenomenon of blocking cannot occur in the process of moving the table top 4 up and down, and the table top 4 is ensured to move more stably.
