DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0023] Such as Figure 1-6As shown in the figure, a lifting column for a household elevator includes an inner column 4 fixedly connected to the top plate and an outer column 5 sleeved on the outer periphery of the inner column 4 and sliding up and down along the outer surface of the inner column 4. The upper end surface of the inner column 4 is fixedly connected with an upper bearing seat 8 by a screw C12, and the lower end surface of the inner column 4 is fixedly connected with a lower bearing seat 2 by a screw D13. An upper bearing 9 is arranged in the upper bearing seat 8, and a lower bearing 3 is arranged in the lower bearing seat 2. The upper end of the screw rod 6 passes through the upper bearing 9 and is connected with the power output component, and the lower end of the screw rod 6 is connected with the lower bearing 3. A slide block nut 7 fixedly connected with the outer column 5 is in spiral fit connection with the outer periphery of the screw rod 6. When the external power input component drives the screw rod 6 to rotate clockwise or counterclockwise, the slide block nut 7 drives the outer column 5 to move up and down along the length direction of the screw rod 6, realizing the lifting of the household elevator.

[0024] In order to improve the installation convenience, an outer column notch 15 is formed on the outer surface of the outer column 5, and an inner column notch 16 is formed on the surface of the inner column 4 opposite to the outer column notch 15. The slide block nut 7 is fixedly connected to the edge of the outer column notch 15 by a screw A10 and extends into the cavity of the inner column 4 through the inner column notch 16, realizing that while the slide block nut 7 moves along the length direction of the screw rod 6, it drives the outer column 5 to move up and down.

[0025] In order to facilitate improving the sliding smoothness of the outer column 5 relative to the inner column 4, mutually cooperating sliding slide rails 1 are fixedly connected to their relative surfaces respectively by screws B11.

[0026] Working principle: External torque is transmitted to the screw rod 6, and the screw rod 6 rotates to drive the nut slider 7 to move up and down along the length direction of the screw rod 6. The outer column 5 fixedly connected to the nut slider 7 moves up and down accordingly. The inner column 4 can be fixed to an external wall surface or other parts through a fixing plate 14. The outer column notch 15 on the outer column 5 can avoid the fixing plate 14 during movement.

[0027] One part of the slide rail 1 is fixedly connected to the inner column 4, and the other part of the slide rail 1 is fixedly connected to the outer column 5. These two parts of the slide rail 1 cooperate to achieve sliding, making the outer column 5 more stable and less likely to shake when moving up and down relative to the inner column 4. A storage plate is arranged between the two outer columns 5, and different components or products can be arranged on the storage plate, thereby realizing the lifting of the component or product.

[0028] The basic principle, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
