Detailed Description

The claimed technical solution of the present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 5, the vertical speaker rack with a jacking and lifting function in this embodiment includes a pipe sleeve, an upright post 2 sleeved with the pipe sleeve and extending and descending relative to the pipe sleeve, a jacking mechanism for driving the upright post 2 to ascend and descend, and a folding leg.

The upper end of the upright post 2 is provided with a connector 21 for connecting a sound box, the middle section of the upright post 2 is formed with an external thread part 22, and the lower section of the upright post 2 is formed with a rotation stopping part 23. The jacking mechanism comprises a threaded sleeve 11 rotatably connected to the upper end of the pipe sleeve and a rotation stopping hole 12 arranged in the lower section of the pipe sleeve, specifically, in the embodiment, the pipe sleeve comprises an upper pipe section 1a and a lower pipe section 1b which are mutually and threadedly connected, and the rotation stopping hole 12 is formed at the lower end of the upper pipe section 1a or the upper end of the lower pipe section 1 b. The threaded sleeve 11 is in threaded engagement with the external threaded portion 22 of the upright 2, while the anti-rotation hole 12 is in engagement with the anti-rotation portion 23 of the upright 2.

Because the threaded sleeve 11 is in threaded fit with the external threaded part 22 of the upright post 2 and cannot rotate relatively before the upright post 2 and the pipe sleeve are matched under the condition that the rotation stopping hole 12 is matched with the rotation stopping part 23 of the upright post 2, the threaded sleeve 11 and the upright post 2 form a ball screw pair, and the upright post 2 can be driven to lift by screwing the threaded sleeve 11. In this embodiment, the threaded sleeve 11 is formed with a holding portion 111 formed on an outer surface of the threaded sleeve 11 and covering the socket, and the user can hold the threaded sleeve 11 by using the holding portion 111 to facilitate screwing the threaded sleeve 11 for height adjustment.

In this embodiment, the folding leg includes three legs 31, three connecting rods 32 and a sliding sleeve 33 sleeved outside the pipe sleeve and slidably engaged with the pipe sleeve, the sliding sleeve 33 is threaded with a locking screw 332, and the surface of the pipe sleeve is provided with a plurality of step holes 13 engaged with the locking screw 332. The sliding sleeve 33 is formed with three annularly distributed pivoting seats 331, the three pivoting seats 331 are pivoted with the three legs 31 one by one, one end of each of the three connecting rods 32 is pivoted with the three legs 31 one by one, and one end of each of the three connecting rods 32 is pivoted with the pipe sleeve. The above structure can realize the folding of the folding legs, and the connecting rod 32 can further improve the structural stability of the folding legs due to the connecting rod 32 connected between the legs 31 and the tube sleeves, and the folding or unfolding state of the folding legs can be maintained due to the above structure since the relative position of the sliding sleeve 33 between the tube sleeves is related to the unfolding degree of the folding legs.

The use of this embodiment is as follows: during installation, the height of the upright post 2 can be adjusted to a lower level, then the sound box is installed on the connector 21 of the upright post 2, and then the threaded sleeve 11 is screwed to drive the upright post 2 to be jacked so as to drive the sound box to rise to a higher height. And the upright post 2 and the thread bush 11 form a ball screw pair, so that the labor-saving effect is achieved when the upright post 2 is jacked.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make further changes and modifications to the invention, or modify equivalent embodiments to equivalent variations, without departing from the scope of the invention.
