[0040] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] like Figures 1 to 4 As shown, the utility model provides a base structure for a display stand, comprising:

[0043] The housing 10 is provided with a mounting cavity 13;

[0044] The counterweight block 20 is located in the installation cavity 13. The counterweight block 20 includes a shell 21 with a hollow interior. The shell 21 is filled with a filler 22. The shell 21 is connected to the outer shell 10. The filler 22 has a certain mass. In the prior art, in order to improve the stability of the product during use, a counterweight metal plate is often installed in the chassis. In order to achieve the required weight, the metal area of the counterweight plate is large and the thickness is relatively thick, the material cost is high, and the manufacturing process generally adopts laser cutting, and the manufacturing cost is also high. In this embodiment, the counterweight block 20 is formed by filling the filler 22 inside the shell 21, which facilitates the selection of more economical materials for the shell 21 and the filler 22, which can not only ensure the counterweight requirements and the stable use of the product, but also reduce the cost of the product.

[0045] In some embodiments, the shell 21 in the counterweight 20 may be made of plastic, and the filler 22 may be a cement mixture or gypsum. The shell 21 includes a body having a filling cavity 211, an injection port communicating with the filling cavity 211, and a sealing cap for sealing the injection port. The cement mixture or gypsum is injected into the filling cavity 211 through the injection port, and the injection port is sealed with the sealing cap. After the cement mixture or gypsum solidifies, it forms the counterweight 20 together with the shell 21. In other embodiments, the filler may be other flowable substances of a certain mass, such as sand, water, etc.

[0046] This embodiment provides a base structure for a display stand, in which a counterweight 20 is formed by filling a shell 21 made of plastic with a cement mixture or gypsum, thereby ensuring stable use of the product while reducing the production cost and processing cost of the product.

[0047] Preferably, the housing 10 includes a bottom plate 11 and a skirt 12 . The skirt 12 is connected to the edge of the bottom plate 11 and extends in the same direction. The bottom plate 11 and the skirt 12 together form a mounting cavity 13 with an opening facing downward.

[0048] In this embodiment, by providing the skirt 12, on the one hand, the strength of the entire shell 10 can be improved, and on the other hand, the counterweight 20 installed in the shell 10 can be prevented from being exposed, thereby improving the aesthetics of the entire base structure.

[0049] Preferably, the base structure also includes a mounting plate 50 , which is disposed in the mounting cavity 13 and located between the housing 10 and the counterweight 20 . The mounting plate 50 is connected to the housing 10 , and the counterweight 20 is connected to the mounting plate 50 .

[0050] It is worth mentioning that since the shell 10 is generally thin, if the counterweight 20 is directly connected to the shell 10, one end of the connection structure between the shell 10 and the counterweight 20 will be exposed on the shell 10, affecting the aesthetics of the entire base structure, and the connection between the two is not very firm.

[0051] In this embodiment, by providing a mounting plate 50, and connecting the mounting plate 50 to the shell 21, the connection position between the counterweight 20 and the shell 10 can be transferred to between the counterweight 20 and the mounting plate 50, and the connection structure between the two can be hidden in the mounting cavity 13 to avoid exposure of the connection structure, thereby not only improving the aesthetics of the entire base structure, but also improving the firmness of the installation of the counterweight 20.

[0052] In addition, the mounting plate 50 and the housing 10 can be integrally arranged, or the connection between the two can be achieved through some fixing method, wherein the fixing method can be selected from bonding, welding, etc., so that the connection structure between the two will not have the risk of being exposed, thereby ensuring the aesthetics of the base structure.

[0053] Optionally, the mounting plate 50 is provided as a flat plate, and the circumferential edge of the mounting plate 50 is welded to the inner wall of the housing 10. A gap is provided between the upper surface of the mounting plate 50 and the lower surface of the bottom plate 11 of the housing 10.

[0054] Optionally, a fastener 30 is further included. The counterweight 20 is provided with a connection hole 212. The fastener 30 passes through the connection hole 212 and is connected to the housing 10 or the mounting plate 50. Specifically, the fastener 30 is a screw. One end of the screw passes through the connection hole 212 of the counterweight 20 and is threadedly connected to the housing 10 or the mounting plate 50, thereby securing the counterweight 20. Preferably, the mounting plate 50 is provided with a threaded hole. One end of the screw passes through the connection hole 212 of the counterweight 20 and is threadedly connected to the threaded hole in the mounting plate 50.

[0055] Further preferably, at least one of the two ends of the connection hole 212 is a funnel-shaped cavity 213. The cavity 213 gradually increases in diameter from the bottom to the surface of the housing 21 where the cavity 213's opening is located, forming a trumpet-like structure. This allows the screw head of the fastener 30 to be concealed within the cavity 213, leaving the exterior of the counterweight 20 smooth.

[0056] It is worth mentioning that when both ends of the connection hole 212 have a funnel-shaped cavity 213 , the entire connection hole 212 presents an hourglass shape.

[0057] Preferably, the base structure further includes a caster 40 , which is connected to one of the housing 10 , the counterweight 20 or the mounting plate 50 .

[0058] In this embodiment, casters 40 are provided to facilitate the movement of the base structure and improve the convenience of using the base structure. If the base structure is applied to a display stand, the movement of the display stand is facilitated.

[0059] It is worth mentioning that the caster 40 has its own braking function. When the base structure reaches the predetermined position, the caster 40 can be self-locked by pressing the self-locking switch on the caster 40, thereby preventing the display stand from moving freely during use and improving the safety of the display stand.

[0060] Further preferably, the counterweight 20 is provided with an escape portion 23, through which one end of the caster 40 passes and is connected to the mounting plate 50. The escape portion 23 can be a notch provided on the edge of the counterweight 20 or an escape hole 214 provided on the counterweight 20. The accompanying drawings only show an example of the escape hole 214. In specific embodiments, the position and number of the escape holes 214 can be adjusted according to actual needs.

[0061] In this embodiment, the provision of a relief notch or relief hole 214 allows the caster 40 to be directly connected to the mounting plate 50. Furthermore, compared to connecting the caster 40 to the counterweight 20, connecting the caster 40 to the mounting plate 50 reduces the height of the entire base structure, thereby lowering the center of gravity of the base structure and further improving the stability of the monitor stand using this base structure during use. Furthermore, the relief hole 214 in this embodiment is located at the center of the counterweight 20 and can serve as a backup mounting location for the caster 40.

[0062] It is further pointed out that the skirt 12 extends downward from the base plate 11, and the height of the skirt is H, the height from the upper surface of the counterweight 20 to the contact point of the caster 40 with the ground is D, and H≥1 / 2D.

[0063] In this embodiment, the reason for specifying the relationship between the height of the skirt 12 and the height from the upper surface of the counterweight 20 to the contact point of the caster 40 with the ground is to ensure that the counterweight 20 and the caster 40 are hidden in the skirt 12 as much as possible while ensuring that the base structure can be moved, thereby improving the aesthetics of the entire base structure.

[0064] The present invention also provides a display stand, including a column 60, one end of which is connected to the base structure of the display stand, and the other end of the column 60 is connected to the arm 70; a head assembly 80 is connected to the arm 70, and the head assembly 80 is used to install the display, etc.
