Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-7As shown, a lifting assembly for a table includes a lifting sleeve 1, a second lifting sleeve 2 slidably disposed within the first lifting sleeve 1, a third lifting sleeve 3 slidably disposed within the second lifting sleeve 2, a third lifting screw 4 rotatably disposed within the third lifting sleeve 3, a second lifting screw 5 rotatably disposed within the third lifting screw 4, a first lifting screw 6 rotatably disposed within the second lifting screw 5, a nut 7 that mates with the third lifting screw 4 installed at the upper end of the third lifting sleeve 3, a limit slider 8 provided between the lower outer periphery of the third lifting screw 4 and the third lifting sleeve 3, and a connecting piece 9 installed at the upper end of the third lifting screw 4 extending beyond the nut 7. Connector 3 9 is connected to the upper end of lifting sleeve 2 2. Connector 3 9 is provided with nut 2 10 that mates with lifting screw 2 5. Limit slider 2 11 is provided between the lower end of lifting screw 2 5 and lifting screw 3 4. The upper end of lifting screw 2 5 extends out of nut 3 7 and is equipped with connector 2 12. Connector 2 12 is connected to the upper end of lifting sleeve 1 1. Connector 2 12 is provided with nut 1 13 that mates with lifting screw 1 6. Limit slider 1 14 is provided between the lower end of lifting screw 1 6 and lifting screw 2 5. The upper end of lifting screw 1 6 extends out of nut 1 13 and is provided with adjusting connection part 15.

[0022] This utility model, through the design of the lifting sleeve, allows the lifting sleeve to move up or down during actual use by adjusting the connecting part 15 and rotating the lifting screw 6, thereby raising or lowering the height of the table.

[0023] During the rotation of the connecting part 15, the lifting screw 16 moves to one side inside the nut 13, and the lifting screw 16 drives the lifting screw 2 5 to rotate synchronously through the limiting slider 14, so that the nut 2 10 drives the lifting sleeve 2 2 to move to one side. The lifting screw 2 5 drives the lifting screw 3 4 to rotate synchronously through the limiting slider 2 11, so that the nut 3 7 drives the lifting sleeve 3 3 to move to one side. Multiple sleeves and screws move synchronously to achieve rapid adjustment.

[0024] The outer periphery of the limiting slider 2 11 is formed with several limiting strips 2 16, and the inner periphery of the lifting screw 3 4 is formed with limiting groove 3 17.

[0025] The outer periphery of the limiting slider 14 is formed with several limiting strips 18, and the inner periphery of the lifting screw 5 is formed with a limiting groove 19 to restrict its rotation and convert its rotational force into the linear movement force of the slider.

[0026] A rotating bearing 20 is provided between the upper outer periphery of the lifting screw 2 5 and the connecting piece 2 12 to improve the stability during rotation.

[0027] The adjustment connection 15 is connected to an adjustment gearbox 21 to facilitate manual adjustment.

[0028] The lower end of the lifting sleeve 3 is equipped with a plug 22, which serves as a support base.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
