Description

Technical Field

[0001] This utility model relates to the field of lifting bracket technology, and in particular to an ultra-thin liftable monitor bracket. Background Technology

[0002] Existing monitor lift stands, as disclosed in the technology, are quite large in cross-section. With technological advancements, and especially with significant changes in people's aesthetic tastes, there is an increasing demand for thinner monitor lift stands. At the same time, users are increasingly pursuing personalization to meet their diverse aesthetic needs. Utility Model Content

[0003] The purpose of this utility model is to provide an ultra-thin height-adjustable monitor stand to solve at least one of the above-mentioned technical problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model provides an ultra-thin height-adjustable monitor stand, comprising: a base, a U-shaped column, a sliding groove, and a lifting assembly;

[0005] The cross-section of the U-shaped column is U-shaped, and there is an internal space that runs through the top and bottom; the U-shaped column has a long strip opening on the front side of the space.

[0006] The sliding component is provided with a sliding groove that runs through the length direction; two sliding components are symmetrically arranged on the left and right sides of the movable space of the U-shaped column.

[0007] The inner end of the lifting component can be slidably inserted into the movable space; the outer end of the lifting component extends out from the elongated opening for connecting the display screen.

[0008] The lifting assembly has rolling elements on its left and right sides that are adapted to the slide groove, and the rolling elements are rotatably inserted into the slide groove.

[0009] In existing technologies, lifting components typically require slide rails to be mounted on the column for vertical movement. However, the thickness of the slide rail structure severely restricts the overall thinness of the lifting support, making it impossible to achieve an ultra-thin lifting support. This application uses independently machined sliding groove components, in conjunction with rolling elements on the lifting component, to replace the slide rail structure in the prior art, thereby eliminating this limiting factor and achieving an ultra-thin lifting support.

[0010] Furthermore, the chute and / or the U-shaped column are extruded metal profiles.

[0011] Preferably, the chute and the U-shaped column are aluminum extrusion profiles.

[0012] Furthermore, the two sliding groove components are vertically arranged at the edge of the elongated opening in the movable space of the U-shaped column.

[0013] Furthermore, the U-shaped column is provided with mounting platforms on the left and right sides of its elongated opening, and the sliding groove is fixedly mounted on the mounting platforms.

[0015] Furthermore, the lifting assembly includes a plate-shaped connecting arm plate; the inner end of the connecting arm plate is slidably inserted into the movable space, and the outer end of the connecting arm plate extends out from the elongated opening.

[0016] Friction blocks are fixedly installed on the left and right sides of the inner end of the connecting arm plate. The outer side of the friction blocks abuts against the left and right sides of the U-shaped column's movable space to generate frictional resistance between the lifting assembly and the column.

[0017] Furthermore, it also includes a constant force spring, the two ends of which include a coiled portion and a connecting piece portion disposed opposite to each other; the coiled portion is rotatably disposed on the inner end of the connecting arm plate and moves up and down with the connecting arm plate;

[0018] The connecting piece is fixedly connected to the U-shaped column; the constant force spring tends to force the lifting assembly to move upward, thereby providing a force to support the display.

[0019] Furthermore, the constant force spring and friction block work together to enable the lifting components and display screen to stop and start during the upgrade process.

[0020] The drum section is rotatably mounted on one side of the connecting arm plate and between the connecting arm plate and the friction block via a spring seat.

[0021] Furthermore, it also includes a connecting block, which is inserted into the bottom of the U-shaped column, and the lower end of the connecting block is connected to the base. That is, the U-shaped column is connected to the base through the connecting block.

[0022] The connecting block is inserted into the U-shaped column, supporting the movable space and improving the overall rigidity of the U-shaped column. Preferably, the connecting block has a slot at its bottom and a protruding socket on the base, allowing the connecting block to be connected and fixed to the base via the slot and socket. Alternatively, the connecting block can be connected to the base using other quick-release and quick-installation connection structures.

[0023] In addition, the connecting block also serves as a lower limiting structure, limiting the downward travel of the lifting component.

[0024] Furthermore, it also includes an upper limit stop, which is inserted into the top of the U-shaped column and extends downward into the movable space to limit the upward travel of the lifting assembly.

[0025] Furthermore, it also includes a left cover, a right cover, a front cover, a rear cover, and a top cover for covering the U-shaped column.

[0026] Preferably, the left side cover, right side cover, front cover, rear cover and top cover are fixed to the U-shaped column by snap-fit ​​methods such as hooks and slots.

[0027] More preferably, the left cover, right cover, front cover, rear cover, and top cover are made of plastic material.

[0028] Preferably, the front cover includes an upper front cover and a lower front cover, the upper front cover is provided with an elongated opening, and the connecting arm plate extends out of the movable space from the elongated opening.

[0029] Additionally, the rear cover can be made separately as an upper rear cover and a lower rear cover, or the upper rear cover and the upper cover can be made as one piece, forming an L-shaped cover plate used to cover the top surface of the U-shaped column and the upper half of the rear end face. The top of the lower rear cover can also be integrally formed with a buckle structure.

[0030] Furthermore, the slide rail includes an extension extending out of the active space, and the extension is provided with a first groove and a second groove formed in one step by an extrusion process, the first groove and the second groove extending through the length direction of the slide rail;

[0031] The front cover is provided with a first hook that is adapted to the first slot; the front cover is fastened to the sliding part by the cooperation of the first hook and the first slot;

[0032] The front ends of the left and right covers are provided with second hooks that are adapted to the second slots; and the rear ends of the left and right covers are provided with snap-fit ​​structures for snapping into each other. During installation, the rear ends of the left and right covers are fastened together by the snap-fit ​​structures, and the front ends of the left and right covers are fixedly connected to the sliding groove by the second hooks and the second slots.

[0055] The cross-section of the U-shaped column 20 is U-shaped, and an internal space that runs vertically through it is provided; the U-shaped column 20 has a long strip opening on the front side of the space.

[0056] The sliding groove 40 is provided with a sliding groove 43 that runs through the length direction; two sliding grooves 40 are symmetrically arranged on the left and right sides of the movable space of the U-shaped column 20.

[0057] like Figure 3 As shown, the inner end of the lifting component 30 is slidably inserted into the active space; the outer end of the lifting component 30 extends out from the elongated opening for connecting the display screen; the left and right sides of the lifting component 30 are provided with rolling elements 31 adapted to the slide groove 43, and the rolling elements 31 are rotatably inserted into the slide groove 43.

[0058] In the prior art, the lifting assembly 30 must typically be mounted on the column using a sliding rail for vertical movement. However, the thickness of the sliding rail structure severely restricts the thinness of the entire lifting support, making it impossible to achieve an ultra-thin lifting support. This application uses an independently machined sliding groove 40, in conjunction with the rolling element 31 on the lifting assembly 30, to replace the sliding rail structure in the prior art, thereby eliminating this limiting factor and achieving an ultra-thin lifting support.
