Description

Technical Field

[0001] This invention relates to the field of electronic screen product support device technology, and in particular to a display screen bracket that can be smoothly adjusted. Background Technology

[0002] In recent years, with the continuous development of society and the advancement of science, the production technology of electronic products has progressed at an increasingly rapid pace, and the frequency of product upgrades has also increased. For example, televisions have evolved from black and white to color televisions, and from desktop televisions to today's LCD flat-screen TVs and computers, greatly enriching people's cultural lives and improving their living standards. Flat-screen TVs and tablets, among other electronic products, have advantages such as being lightweight and space-saving, making them convenient for viewing and use. People typically use movable stands to fix these electronic products to tables or walls for use.

[0003] Currently, the existing patent, titled "A Movable Support Frame," with patent number 201420151704.4, proposes a technical solution that utilizes a force-applying mechanism to provide a thrust to the concave wheel component, causing the cam surface of the concave wheel component to abut against the roller on the fixed seat. The roller provides a supporting force to the concave wheel component, and this supporting force F forms an upward-sloping component F1 on the cam surface. This component F1 is transmitted to the connecting seat through the force-applying mechanism and connecting rod, allowing the connecting seat to support an object of a certain weight, such as a monitor or television screen. When the weight T of the supported object is the same as the component F1, the supported object can remain at a certain position. Furthermore, since the component F1 is equal at any position on the cam surface, the object supported on the connecting seat can be adjusted to stay at any height, resulting in stepless adjustment and providing convenience and flexibility in adjustment. However, this technical solution still has defects. When adjusting the position, there is insufficient fit between the cam surface of the force application mechanism and the roller, and the spring of the force application mechanism is prone to wobble during adjustment, resulting in the movable support frame not being adjusted smoothly.

[0004] Therefore, there is an urgent need in the market for a smoothly adjustable display stand to solve this problem. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by proposing a smoothly adjustable display screen bracket. The addition of a limiting sleeve structure design encloses the pressure spring, preventing it from swaying during adjustment. This effectively prevents the connecting rod assembly from becoming unstable, difficult to move, or not moving smoothly during adjustment, making it highly practical.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smoothly adjustable display screen bracket includes: a first connecting seat, a connecting rod assembly, and a second connecting seat. The connecting rod assembly is disposed between the first connecting seat and the second connecting seat. The connecting rod assembly includes a connecting rod, a force-applying mechanism, a limiting sleeve, a concave wheel component, and a roller. The roller is rotatably mounted on the second connecting seat. One end of the force-applying mechanism is connected to the first connecting seat, and the other end of the force-applying mechanism is connected to the concave wheel component. Under the pushing action of the force-applying mechanism, the concave wheel surface of the concave wheel component abuts against the roller. The limiting sleeve covers the outer side of the force-applying mechanism.

[0008] As a further explanation of the above technical solution:

[0009] In the above technical solution, the force-applying mechanism includes a pressure spring, one end of which abuts against the concave wheel.

[0010] In the above technical solution, the force-applying mechanism further includes a hanging plate, an adjusting screw, and an adjusting moving block. One end of the hanging plate is pivotally connected to the first connecting seat. The adjusting screw is engaged with the hanging plate through a screw head. The adjusting moving block is screwed onto the adjusting screw. The pressure spring is sleeved on the outside of the adjusting screw and its two ends abut against the adjusting moving block and the concave wheel. The limiting sleeve covers the outside of the pressure spring.

[0011] In the above technical solution, the limiting sleeve includes a flexible sleeve, the inner diameter of which is adapted to the outer diameter of the pressure spring, and the flexible sleeve covers the outside of the pressure spring.

[0012] In the above technical solution, the limiting sleeve includes a rigid sleeve, the inner diameter of which is adapted to the outer diameter of the pressure spring, and the rigid sleeve covers the outside of the pressure spring.

[0013] In the above technical solution, the limiting sleeve includes a flexible sleeve and a rigid sleeve. The inner diameter of the flexible sleeve is adapted to the outer diameter of the pressure spring, and the inner diameter of the rigid sleeve is adapted to the outer diameter of the flexible sleeve. The flexible sleeve covers the outside of the pressure spring, and the rigid sleeve covers the outside of the flexible sleeve.

[0014] In the above technical solution, the connecting rod includes a first connecting rod and a second connecting rod. The second connecting rod covers the upper end of the first connecting rod. One end of the first connecting rod is pivotally connected to a first connecting seat, and the other end of the first connecting rod is pivotally connected to a second connecting seat. One end of the second connecting rod is pivotally connected to the first connecting seat, and the other end of the second connecting rod is pivotally connected to the second connecting seat. The rigid sleeve is fixed to the second connecting rod by screws.

[0015] In the above technical solution, the second connecting rod is provided with a concave wheel sleeve that is adapted to the concave wheel component. The concave wheel component is slidably disposed at the concave wheel sleeve, and the concave wheel sleeve is fixed to the second connecting rod by screws.

[0016] In the above technical solution, the roller is located at the front side between the pivot joint of the first connecting rod, the second connecting rod and the second connecting seat.

[0017] The above technical solution also includes a mounting base, a connecting bracket, and a fixing base.

[0018] Compared with the prior art, this invention has significant advantages and beneficial effects. Specifically, it has a novel structure and reasonable design. By adopting a new limiting sleeve and a concave wheel sleeve, and reducing the structural design of the center rod, the flexible sleeve wraps around the pressure spring, and the rigid sleeve further restricts it, preventing the pressure spring from swinging during adjustment. This effectively prevents the connecting rod assembly from being unstable, difficult to move, or not moving smoothly during adjustment. It also provides a stepless adjustment effect, making the adjustment convenient, flexible, and highly practical.

[0019] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Attached Figure Description
