Detailed Description

For a better understanding of the objects, structure and function of the utility model, a telescopic assembly and a fan of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the telescopic assembly of the present invention includes a fixed tube 1 and a lifting rod 2, wherein one end of the lifting rod 2 is sleeved in the fixed tube 1, and the other end of the lifting rod extends out of the fixed tube 1, so that the lifting rod 2 is connected with the fixed tube 1 in a sliding manner and can lift along the fixed tube 1.

In order to drive the lifting rod 2 to lift, the lifting rod 2 is provided with a driving rod 3 which is controlled to rotate, a driving thread 13 is formed on the inner wall of the fixed pipe 1, and the driving thread 13 is in threaded connection with the driving rod 3, so that the lifting rod 2 is driven to lift along with the rotation of the driving rod 3.

Specifically, the lower end of the lifting rod 2 is formed with a mounting groove, the motor 4 driving the driving rod 3 is fixed in the mounting groove, and the output shaft of the motor 4 extends out of the mounting groove and is fixed with the end of the driving rod 3, so that the driving rod 3 is driven to rotate. Generally, the output shaft is a flat shaft, and the end of the driving rod 3 is provided with a step groove for the flat shaft to be inserted.

As shown in fig. 5 to 9, in order to ensure the stable rotation of the driving rod 3, the lifting rod 2 forms side plates 21 oppositely disposed at two sides of the driving rod 3, a support plate 22 is fixedly connected to one end of each of the side plates 21 far from the lifting rod 2 through a screw, and the support plate 22 is rotatably connected to the lifting rod 2 and is radially fixed thereto. Generally, the support plate 22 is formed with a boss 221, and the active lever 3 is formed with a groove into which the boss 221 is inserted.

Thereby connecting the motor 4 and the boss 221 to both ends of the driving lever 3, respectively, to drive the driving lever 3 to rotate.

Because it is troublesome to set up the screw thread on the fixed pipe 1 inner wall, therefore the dead lever includes outer tube 11, and outer tube 11 inboard rigid coupling has inner tube 12, and drive screw thread 13 sets up on inner tube 12. Specifically, the inner wall of the outer tube 11 is formed with a rib 111 arranged along the circumferential direction, and the inner tube 12 is inserted inside the rib 111 to prevent the inner tube 12 and the outer tube 11 from being separated.

In order to close the gap between the inner tube 12 and the outer tube 11, an annular cover plate 5 is fixed to the end of the inner tube 12, and the annular cover plate 5 covers the gap between the inner tube 12 and the outer tube 11. The annular cover plate 5 is formed with a snap 51 arranged around the inner tube 12, and the inner tube 12 is provided with a clamping groove 121 for clamping the snap 51, so that the annular cover plate 5 is fixed on the inner tube 12. Specifically, one end of the elastic arm of the buckle 51 is fixed to the annular cover plate 5, and the other end is formed with a clamping block which is clamped into the clamping groove 121. And the side of the resilient arm is in surface contact with the inner tube 12.
