Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, and in particular to a sleeve-type lifting structure for products such as displays and all-in-one computers. Background Art

[0002] Current monitors, all-in-one computers and other products are usually installed using a lifting device so that the height can be easily adjusted. Currently, most mainstream lifting structures use metal slide rail solutions, and a small number use aluminum extruded sleeves + die-castings + POM wheels or bearings to achieve lifting. However, most existing lifting structures of this type have defects such as complicated assembly procedures, low efficiency, and high material costs, resulting in a decline in competitiveness. At the same time, since the limit of the lifting process is mainly provided by the contact between the POM wheel inside the sleeve and the surface of the inner wall of the sleeve, the lifting structure is prone to loosening and shaking, and the lifting operating force cannot meet the specification requirements due to insufficient friction, such as the lifting operating force cannot meet the 1kg requirement. Utility Model Content

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a sleeve slider type lifting structure, comprising a sleeve, a sliding block and a roller, the roller is installed on the sliding block, and the sliding block is installed in the sleeve, and is characterized in that: a pressure rib is provided on the inner wall of the sleeve at a position opposite to the roller, the pressure rib extends from top to bottom along the axial direction of the sleeve, and the roller abuts against the surface of the pressure rib; elastic arms are respectively provided on both sides of the sliding block, and a friction bone position is provided on the inner wall of the sleeve at a position opposite to the elastic arm, the friction bone position extends from top to bottom along the axial direction of the sleeve, and the friction bone position and the elastic arm are in contact with each other in a front-to-back relative posture.

[0005] Furthermore, the elastic arm includes a front elastic arm and a rear elastic arm, the front elastic arm abuts against the front surface of the friction bone position, and the rear elastic arm abuts against the rear surface of the friction bone position.

[0006] Furthermore, the front elastic arm and the rear elastic arm are of a structure with one higher and one lower and staggered with each other, and a group of front elastic arms and rear elastic arms are respectively provided at upper and lower positions on the left and right sides of the sliding block.

[0007] Furthermore, a roller is provided on the upper front portion of the sliding block near the left and right sides, and the two rollers are respectively connected to pressure ribs.

[0008] Furthermore, a guide protrusion is provided on the back side of the sliding block in the longitudinal direction, and a limiting rib is provided on the inner wall of the sleeve at a position corresponding to the guide protrusion. The limiting rib is divided into a guide limiting groove, and the guide protrusion is embedded in the guide limiting groove.

[0009] Furthermore, a constant force spring is installed in the sliding block, and the tail end of the constant force spring presses against the inner wall of the sleeve opposite to the back of the sliding block to push the sliding block forward so that the roller presses against the pressing rib.

[0010] Preferably, the sleeve is made of plastic material, and the sliding block and the roller are both made of POM material.

[0011] Furthermore, a top cover assembly is installed on the top of the sleeve, and the sliding block and the roller are covered by the top cover assembly to prevent dust and other debris from entering.

The roller 3 is installed on the sliding block 2, and the sliding block 2 is installed in the sleeve 1; a pressure rib 11 is provided on the inner wall of the sleeve 1 at a position opposite to the roller 3, and the pressure rib 11 extends from top to bottom along the axial direction of the sleeve 1, and the roller 3 abuts against the surface of the pressure rib 11 to support the roller 3, so that the sliding block is more stable and shakes less when sliding up and down; elastic arms are provided on both sides of the sliding block 2, and a friction bone position 12 is provided on the inner wall of the sleeve 1 at a position opposite to the elastic arm. The friction bone position 12 extends from top to bottom along the axial direction of the sleeve 1, and the friction bone position 12 contacts the elastic arm in a front-to-back relative posture.

[0022] The elastic arm includes a front elastic arm 21 and a rear elastic arm 22. The front elastic arm 21 abuts the front surface of the friction bone 12, while the rear elastic arm 22 abuts the rear surface of the friction bone 12. This effectively embeds the friction bone 12 between the front and rear elastic arms 21 and 22. This not only solves the problem of insufficient friction causing the lifting operating force to fail to meet specification requirements, but also further improves the stability of the lifting structure and prevents it from loosening.

[0023] The front elastic arm 21 and the rear elastic arm 22 are staggered with one higher and one lower. A set of front elastic arms 21 and rear elastic arms 22 are respectively provided at upper and lower positions on the left and right sides of the sliding block 2 .

[0025] A guide protrusion 23 is provided longitudinally on the back side of the sliding block 2, and a limiting rib 13 is provided on the inner wall of the sleeve 1 at a position corresponding to the guide protrusion 23. The limiting rib 13 is divided into a guide limiting groove, and the guide protrusion 23 is embedded in the guide limiting groove to improve the stability of the lifting process.

[0026] A constant force spring 4 is installed in the sliding block 2, and the tail end of the constant force spring 4 presses against the inner wall of the sleeve 1 and the back of the sliding block 2 to push the sliding block 2 forward so that the roller 3 presses against the pressing rib 11, reducing the shaking during the lifting process.

[0027] The sleeve 1 is made of plastic material, and the sliding block 2 and the roller 3 are both made of POM material, namely the POM sliding block and the POM roller.

[0028] A top cover assembly 6 is installed on the top of the sleeve 1 to cover the sliding block 2 and the roller 3 to prevent dust and other debris from entering.

[0029] A sliding hole 14 is provided on the front side of the sleeve 1 along its axial direction. A mounting base 5 for mounting devices such as a display and an all-in-one machine is fixedly connected to the sliding block 2 via a connecting bracket passing through the sliding hole 14 .
