Therefore, they cannot be understood as limitations on the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0044] like Figure 1-6 As shown, the utility model discloses a display stand, including a stand body 10 and a lifting assembly 20, wherein the stand body 10 is provided with an activity space 11, and the outer wall of the stand body 10 is provided with a longitudinal opening 12 communicated with the activity space 11, and the lifting assembly 20 can be slid up and down in the activity space 11, and the lifting assembly 20 includes a lifting seat 21 and a constant force spring (not shown) arranged on the lifting seat 21, and the mounting portion 211 on the lifting seat 21 extends out of the longitudinal opening 12, and the mounting portion 211 can be used to install the display, and the lifting seat 21 and the stand body 10 are both connected to the constant force spring, and the constant force spring can realize that the lifting seat 21 stays at any height position, wherein the constant force spring adopts a coil spring.

[0045] The lifting assembly 20 also includes a first slide 22 and a second slide 23, both of which are made of plastic. The first slide 22 and the second slide 23 are respectively installed on the left and right sides of the lifting seat 21. The lifting seat 21 is slidably arranged in the activity space 11 through the first slide 22 and the second slide 23. The left side wall of the first slide 22 is provided with a plurality of first elastic friction plates 221 extending obliquely upward, and the right side wall of the second slide 23 is provided with a plurality of second elastic friction plates 231 extending obliquely upward.

During assembly, the upper end of the first elastic friction plate 221 is pressed by the inner wall of the first slide groove 13, so that the upper end of the first elastic friction plate 221 is elastically deformed and shrinks inward. At this time, the elastic force inside the first elastic friction plate 221 will keep the upper end of the first elastic friction plate 221 in contact with the inner wall of the first slide groove 13. The principle of the second elastic friction plate 231 is the same as that of the first elastic friction plate 221.

[0046] The first elastic friction plates 221 include a left elastic friction plate 2211, a first front elastic friction plate 2212 and a first rear elastic friction plate 2213. The left elastic friction plate 2211, the first front elastic friction plate 2212 and the first rear elastic friction plate 2213 are respectively in sliding contact with the corresponding three adjacent inner walls of the first slide groove 13.

[0049] The angles between the left elastic friction plate 2211, the first front elastic friction plate 2212, the first rear elastic friction plate 2213 and the right elastic friction plate 2311 and the horizontal plane are 40 degrees-50 degrees. Preferably, the angles between the left elastic friction plate 2211 and the right elastic friction plate 2311 and the horizontal plane are 40 degrees. Preferably, the angles θ between the first front elastic friction plate 2212 and the first rear elastic friction plate 2213 and the horizontal plane are 45 degrees. By adopting the left elastic friction plate 2211, the first front elastic friction plate 2212 and the first rear elastic friction plate 2213 with angles of 40 degrees-50 degrees, when the lifting seat 21 moves upward, a suitable damping effect is provided between the first slide seat 22 and the first slide groove 13.

There are multiple first front elastic friction plates 2212 and first rear elastic friction plates, which are spaced apart along the up and down directions. By setting two left-side elastic friction plates 2211 and arranging the first front elastic friction plate 2212 and the first rear elastic friction plate 2213 between the two left-side elastic friction plates 2211, the contact points between the first slide seat 22 and the first slide groove 13 are reasonably arranged with good balance, which is conducive to improving stability.
