Description

Technical Field

[0001] This utility model relates to a seat pressing structure that is convenient to extend and adjust. Background Technology

[0002] The primary function of chairs or stools is to provide a place for people to rest. Traditional chairs or stools are generally fixed, taking up a lot of space and being inconvenient to store. To solve these problems, foldable chairs were developed, and they are widely popular because they are easy to store and take up little space. In existing technology, there are many types of folding chairs, but their folding methods and structures vary. One type of folding chair has cross-shaped support legs. One pair of support legs is hinged to the seat at the top, while the other pair has telescopic legs that are hinged to the seat. The seat can be unfolded and folded by controlling the extension or retraction of the telescopic legs. After the telescopic legs and support legs are extended or retracted, they are fixed or unlocked by a flexible locking point. When the locking point inside the telescopic leg is pressed inward into the hole on the support leg, the telescopic leg can be moved. When the locking point inside the telescopic leg is engaged in the fixing hole on the support leg, the telescopic leg and support leg are relatively fixed, serving as a limit. However, because the locking point is relatively small, it is difficult for the operator to find during use. At the same time, it is difficult to operate when pressing the elastic locking point, requiring considerable force to press it in. Utility Model Content

[0003] This invention addresses the aforementioned problem by providing a convenient telescopic and adjustable seat pressing structure that is simple in structure and easy to operate.

[0004] This utility model is constructed as follows: it includes a fixing kit disposed on the upper end of the outer leg tube of the folding chair assembly; a retractable pull tube is sleeved on the upper end of the outer leg tube; the pull tube and the outer leg tube are limited by an elastic button assembly; a rotating plate is hinged to the fixing kit; and a pressure block is provided on the inner side of the rotating plate for conveniently pressing the elastic button assembly into the unlocking position, so as to unlock the outer leg tube and the retractable tube.

[0005] Furthermore, the upper end of the outer leg tube is provided with a limiting slot, and the upper side of the fixing kit is provided with a limiting block for cooperating with the limiting slot.

[0006] Furthermore, the rotating plate and the fixed assembly are hinged via a pin.

[0007] Furthermore, the folding chair assembly includes outer leg tubes, inner leg tubes, and a seat plate. The two upper ends of the inner leg tubes and the upper ends of the two pull tubes are respectively hinged to the seat plate. The outer leg tubes include two outer tubes and an outer horizontal tube disposed at the lower part of the two outer tubes. The inner leg tubes include two inner tubes, an inner middle horizontal tube disposed in the middle of the two inner tubes, and an inner lower horizontal tube disposed at the lower part of the two inner tubes. The two inner tubes are respectively hinged to the two outer tubes.

[0008] Furthermore, the elastic button assembly includes an elastic element disposed inside the core-pulling tube. A through hole is provided on the side wall of the core-pulling tube, and a button that can move along the through hole is disposed in the through hole.

[0014] Compared with existing technologies, this utility model has the following advantages: The device has a simple structure, reasonable design, and is easy to use. When the folding chair assembly needs to be stored, the fixed kit allows for a clear view of the adjustment position. By pressing the rotating plate inward, the pressure block pushes the button of the elastic button assembly into the through hole of the fixed kit, causing the outer leg tube and pull tube to lose their restraints and move freely. Pulling the pull tube upward allows the seat to rotate along the inner leg tube, achieving the function of folding the chair. When the folding chair assembly needs to be unfolded, the pull tube moves downward along the outer leg frame, causing the elastic button assembly on the pull tube to engage with the through hole of the fixed sleeve on the outer leg frame, thus locking the outer leg tube and pull tube, thereby completing the unfolding and fixing of the entire chair. This device, by setting a dedicated rotating plate and pressure block at the button position, facilitates pushing the button of the elastic button assembly into the fixed sleeve, thereby unlocking the outer leg tube and pull tube. The operation is simple and greatly improves operational efficiency. Attached Figure Description
