Abstract
Description
Technical Field
[0001] The utility model relates to the field of daily necessities, and specifically relates to a chair armrest that can be adjusted at multiple angles. Background Art
[0002] Chairs are a very common daily necessity in people's daily lives and are widely used in homes, offices and other places. Chairs are usually composed of a seat and a backrest. In order to provide a more comfortable resting effect, armrests are installed on both sides of the chair to facilitate people to put their hands on the armrests during use. However, chair users have different heights, weights, and sitting postures due to work and entertainment on the chair. Therefore, there is a great demand for angle adjustment of the armrests on both sides of the seat. At present, the armrests on conventional chairs are all set to a fixed structure. The armrests themselves cannot be adjusted, which does not provide a more effective resting effect and is inconvenient to use. Utility Model Content

[0004] In order to solve the above-mentioned existing technical problems, the present invention adopts the following solution: a seat armrest that is easy to adjust, including an armrest and a bracket, the armrest is installed on the bracket, an adjustment seat is provided at the bottom of the armrest, and an adjustment switch is provided on the side of the adjustment seat. The bottom of the adjustment switch is connected to the tensioning structure in the bracket, and the bottom of the bracket is connected to the seat through a connecting piece.
[0005] Preferably, the armrest is provided with a mounting groove, and a slider is installed on the mounting groove.
[0006] Preferably, a plurality of bearings are provided on both sides of the adjustment seat, and the bearings are respectively connected to gasket 1 and gasket 2, gasket 1 is placed on the inner side of the upper mounting cover, and gasket 2 is placed on the inner side of the lower mounting cover, the connecting hole on gasket 1 is connected to the tensioning structure, and a torsion spring is installed on the mounting shaft above the tensioning structure, hook 1 and hook 2 on the tensioning structure are connected to the adjustment seat, and the end of the tensioning structure is installed on the connecting piece through a connecting piece, and an upper rack is installed on the tensioning structure, the upper rack is meshed with the lower rack, and the lower rack is installed at the bottom of the bracket.
[0007] Preferably, the end of the torsion spring is mounted on a limiting groove on the tensioning structure.
[0008] Preferably, the bottom of the adjustment seat is provided with an arc structure.
[0009] Preferably, the connecting member is provided with a continuous arc structure, and the arc structure matches the arc surfaces of the ends of the upper mounting cover and the lower mounting cover.
[0010] The utility model adopts the above technical solution to provide a chair armrest that is easy to adjust. It can simulate human joints and can be adjusted up and down, front and back, left and right, greatly reducing human fatigue. Compared with the existing technology, it has the following advantages:
[0011] 1. Install the bottom of the bracket on the side of the seat through the connector. The armrest and backrest are independent of each other, and the angles of the armrest and backrest can be adjusted independently.
[0012] 2. Press the adjustment switch to drive the adjustment frame to disengage the upper rack and lower rack on the tensioning structure, making it easier to adjust the armrest. BRIEF DESCRIPTION OF THE DRAWINGS
