[0001] This utility model relates to the field of monitor stand technology, and more specifically, to a height-adjustable monitor stand. Background Technology

[0002] A monitor is an electronic output device used to display images, videos, text and other information. It is a core component of systems such as computers, game consoles and televisions. A monitor stand is a device used to fix and adjust the position of a monitor. It is designed to optimize user comfort through multi-directional adjustment functions, while saving space and improving the working environment.

[0003] For example, application number CN202020636325.X discloses an adjustable height monitor stand. By adjusting the handle, the engagement and disengagement of the limiting block and the teeth can be achieved to move up and down. The height can also be adjusted by fixing it at any point on the rack. In the prior art, the vertical height adjustment range of some stands is limited. Moreover, during the height adjustment process of the monitor stand, when limiting the height after adjustment, the locking device may fail. That is, the joint screws of the stand need to compromise between "tightening so that it cannot rotate" and "loosening so that the monitor sags", which affects the adjustment experience.

[0004] Therefore, a height-adjustable monitor stand is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a height-adjustable monitor stand to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable monitor stand, comprising a base, a support column, a height adjustment component, and a connecting plate. The support column is provided on the upper surface of the base, and the height adjustment component is provided on the end of the support column away from the base. The connecting plate is provided on the movable end of the height adjustment component.

[0007] The up-down adjustment assembly includes a housing and a limiting strip. The housing has a limiting strip inside its cavity, and there are two sets of limiting strips. A sliding groove is longitudinally provided through the side end face of the housing. A first limiting hook is provided on the side of the limiting strip away from the connecting plate. An adjustment block is provided inside the housing, and a second limiting hook is provided on the side of the adjustment block near the first limiting hook. A threaded rod is transversely provided through the center of the side end face of the adjustment block, and a threaded groove is provided on the contact surface between the adjustment block and the threaded rod. A handwheel is provided at one end of the threaded rod.

[0008] Preferably, the side end face of the connecting plate is provided with a connecting hole, and a connecting seat is provided at the center of the side of the connecting plate away from the connecting hole. Limiting posts are provided above and below the connecting seat. The connecting seat on the side end face of the connecting plate is connected to the end of the threaded rod away from the handwheel through a bearing.

[0009] Preferably, the base is triangular, the support column is composed of a grid plate and a reinforcing plate, the grid plate in the support column forms a hollow cuboid shape, and the inner cavity of the hollow cuboid grid plate is provided with a reinforcing plate, and the reinforcing plate is arranged in an X-shape. The grid plate and the reinforcing plate in the base and the support column are both made of carbon fiber material.

[0010] Preferably, the limiting strips in the inner cavity of the housing are symmetrically arranged, and the second limiting hooks on the side end face of the adjusting block are symmetrically arranged. The widths of the first limiting hooks on the side end face of the limiting strips and the second limiting hooks on the side end face of the adjusting block are the same.

[0011] Preferably, the threaded rod and the adjusting block form a threaded connection structure through the threaded groove, and the housing forms a sliding structure through the threaded rod arranged through the side end face of the adjusting block via the sliding groove.

[0012] Preferably, the connecting plate forms a sliding structure with the sliding groove on the side end face of the housing through the connecting seat and the limiting post, and the side end face of the connecting plate is limited and connected to the threaded rod through the bearing.

[0013] Preferably, the outer diameter surface of the bearing is limited to the connecting seat, and the inner diameter surface of the bearing is limited to the outer surface of one end of the threaded rod. The threaded rod forms a rotating structure around the center of the bearing through the bearing and the connecting seat.

[0014] Preferably, the first limiting hook on the side end face of the limiting strip and the second limiting hook on the side end face of the adjusting block form a fastening structure, and the first limiting hook and the second limiting hook are evenly arranged on the side end faces of the limiting strip and the adjusting block.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this height-adjustable monitor stand has an advantage in that the limiting strip and the first limiting hook in the height adjustment component for supporting the display screen are engaged with the adjustment block and the second limiting hook. At the same time, due to gravity, the first limiting hook and the second limiting hook are tightly fitted together, thereby achieving stable and high-strength limiting of the adjusted state. This avoids the need for the joint screws of the stand to compromise between "tightening so that it cannot rotate" and "loosening so that the monitor sags", which would affect the adjustment experience.

[0017] Compared with existing technologies, this height-adjustable monitor stand features a height adjustment mechanism that allows for adjustment of the connecting plate's height via a vertical adjustment component. Two sets of limiting strips are provided within the housing cavity, and a first limiting hook on the side end of the limiting strip and a second limiting hook on the side end of the adjustment block form a locking structure, facilitating height adjustment of the connecting plate. When adjusting the connecting plate's height, manually rotating the handwheel causes the threaded rod to rotate. The threaded rod, through a threaded groove, moves the adjustment block away from or closer to the limiting strip, enabling the first and second limiting hooks to engage and disengage, thus facilitating height adjustment. Simultaneously, the engagement of the first and second limiting hooks helps to limit the adjusted state, preventing the joint screws from having to compromise between "tightening to prevent rotation" and "loosening causing the monitor to sag," which negatively impacts the adjustment experience. Furthermore, during height adjustment, the threaded rod slides up and down against the housing via a groove, ultimately facilitating height adjustment of the connecting plate.

[0018] Compared with existing technologies, this height-adjustable monitor stand uses a base and support column to adjust the height of the components and the display screen. The support column is composed of a grid plate and a reinforcing plate, which improves the strength of the device while reducing its weight. The connecting plate is connected to an external display screen through connecting holes, and the connecting plate forms a sliding structure with the sliding groove on the side end face of the housing through a limiting post. It is also limited by the connecting seat and bearing and the threaded rod, which facilitates the height adjustment of the connecting plate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] As attached Figures 1 to 6 The illustrated height-adjustable monitor stand includes a base 1, a support column 2, a height adjustment component 3, and a connecting plate 4. The support column 2 is provided on the upper surface of the base 1, and the height adjustment component 3 is provided on the end of the support column 2 away from the base 1. The height of the connecting plate 4 is adjusted by the height adjustment component 3. The connecting plate 4 is provided on the moving end of the height adjustment component 3. The height adjustment component 3 includes a housing 31 and a limiting strip 32. The limiting strip 32 is provided in the inner cavity of the housing 31, and there are two sets of limiting strips 32. The limiting strips 32 in the inner cavity of the housing 31 are symmetrically arranged. A sliding groove 33 is provided longitudinally through the side end face of the housing 31. A first limiting hook 34 is provided on the side of the limiting strip 32 away from the connecting plate 4. An adjustment block 35 is provided in the inner cavity of the housing 31, and a second limiting hook 36 is provided on the side of the adjustment block 35 near the first limiting hook 34.

[0029] The second limiting hook 36 on the side end face of the adjusting block 35 is symmetrically arranged. The first limiting hook 34 on the side end face of the limiting strip 32 and the second limiting hook 36 on the side end face of the adjusting block 35 have the same width. Both the first limiting hook 34 and the second limiting hook 36 are made of titanium alloy. A threaded rod 37 is transversely arranged through the center of the side end face of the adjusting block 35. The housing 31 forms a sliding structure with the threaded rod 37 arranged through the side end face of the adjusting block 35 through the sliding groove 33. When adjusting the height of the connecting plate 4, the threaded rod 37 slides up and down with the housing 31 through the sliding groove 33, which facilitates the adjustment of the height of the connecting plate 4. The contact surface between the adjusting block 35 and the threaded rod 37 is provided with a threaded groove 38. The threaded rod 37 forms a threaded connection structure with the adjusting block 35 through the threaded groove 38. A handwheel 39 is provided at one end of the threaded rod 37. When adjusting the height of the connecting plate 4... Manually rotating the handwheel 39 causes the threaded rod 37 to rotate. The threaded rod 37, through the threaded groove 38, moves the adjusting block 35 away from or closer to the limiting strip 32, thus enabling the first limiting hook 34 and the second limiting hook 36 to engage and disengage. This facilitates the adjustment of the height of the connecting plate 4. Simultaneously, the engagement of the first limiting hook 34 and the second limiting hook 36 helps to limit the adjusted state. The first limiting hook 34 on the side end of the limiting strip 32 and the second limiting hook 36 on the side end of the adjusting block 35 form an engaging structure, further facilitating the adjustment of the height of the connecting plate 4. Furthermore, the first limiting hook 34 and the second limiting hook 36 are evenly arranged on the side end faces of the limiting strip 32 and the adjusting block 35. This structure avoids the need for the bracket's joint screws to compromise between "tightening to prevent rotation" and "loosening causing the monitor to sag," thus affecting the adjustment experience.

[0030] The base 1 is triangular in shape. The support column 2 is composed of a grid plate 21 and a reinforcing plate 22. The grid plate 21 in the support column 2 forms a hollow cuboid shape, and the inner cavity of the hollow cuboid grid plate 21 is provided with reinforcing plates 22, which are arranged in an X-shape. The grid plate 21 and the reinforcing plate 22 in the base 1 and the support column 2 are both made of carbon fiber material, which improves the strength of the device while reducing its weight. The side end face of the connecting plate 4 has a connecting hole 41. The connecting plate 4 is connected to an external display screen through the connecting hole 41. A connecting seat 42 is provided at the center of the side of the connecting plate 4 away from the connecting hole 41. Limiting posts 43 are provided above and below the connecting seat 42. The connecting seat 42 on the side end face of the connecting plate 4 is connected to the end of the threaded rod 37 away from the handwheel 39 through a bearing 44. The connecting plate 4 is connected to the end of the threaded rod 37 away from the handwheel 39 through the bearing 44. The connecting seat 42 and the limiting post 43 form a sliding structure with the sliding groove 33 on the side end face of the housing 31. The side end face of the connecting plate 4 is limited and connected to the threaded rod 37 through the bearing 44. The outer diameter surface of the bearing 44 is limited and connected to the connecting seat 42, and the inner diameter surface of the bearing 44 is limited and connected to the outer surface of one end of the threaded rod 37. The threaded rod 37 forms a rotating structure around the center of the bearing 44 through the bearing 44 and the connecting seat 42. The connection between the connecting seat 42 and the bearing 44 and the threaded rod 37 facilitates the adjustment of the height of the connecting plate 4. In this embodiment, titanium alloy and carbon fiber are commercially available and well-known to those skilled in the art. They can be customized or selected according to actual needs. Here we only use them without making any structural or functional improvements, and we will not go into details here.

[0031] The working process of this utility model is as follows: The height of the connecting plate 4 is adjusted using the up-down adjustment component 3. When adjusting the height of the connecting plate 4, the handwheel 39 is manually rotated, which drives the threaded rod 37 to rotate. The threaded rod 37 uses the threaded groove 38 to move the adjusting block 35 away from or closer to the limiting strip 32, thereby achieving the engagement and disengagement of the first limiting hook 34 and the second limiting hook 36. This adjusts the height of the connecting plate 4 by using the engagement of the first limiting hook 34 and the second limiting hook 36, which is convenient for adjusting the height of the connecting plate 4. The adjusted state is limited, and when adjusting the height of the connecting plate 4, the threaded rod 37 slides up and down with the housing 31 through the slide groove 33, which makes it easy to adjust the height of the connecting plate 4. The base 1 and the support column 2 are used to adjust the up and down adjustment components 3 and the display screen. The connecting plate 4 is connected to the external display screen through the connecting hole 41, and the connecting plate 4 forms a sliding structure with the slide groove 33 on the side end face of the housing 31 through the limiting column 43. It is limited and connected to the threaded rod 37 through the connecting seat 42 and the bearing 44, which makes it easy to adjust the height of the connecting plate 4.
