Description

Technical Field

[0001] This utility model belongs to the field of home seat technology, specifically relating to a home seat locking and adjustment structure. Background Technology

[0002] Home chairs are seating pieces with backrests, and some also have armrests. They are usually designed to be more ergonomic, aiming to provide a comfortable sitting experience. Currently, most home chairs have the function of adjusting the seat height.

[0003] Existing seat locking and adjustment mechanisms typically rely on bolts for locking and limiting, requiring the bolts to be tightened and loosened during seat raising and lowering operations. This significantly reduces the seat's adjustment efficiency, is inconvenient for operators, and diminishes the practicality of the seat locking and adjustment mechanism. Furthermore, existing seat locking and adjustment mechanisms are difficult to separate from the seat, making it inconvenient to place and transport the seat during production and shipping, increasing the space occupied when storing the seat, and reducing the convenience of the seat locking and adjustment mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a locking and adjusting structure for home use seats, in order to solve the problems that existing seat locking and adjusting structures greatly reduce the adjustment efficiency of seats and make it difficult to separate them from the seats.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a household seat locking and adjustment structure, comprising: a base, a support column connected to the top of the base, an annular plate sleeved on the outer wall of the support column, support plates symmetrically connected to both sides of the annular plate, and a seat body connected to the top of the two support plates; a locking assembly, the locking assembly being disposed between the annular plate and the support column, the locking assembly including a connecting frame, two connecting frames symmetrically connected to both sides of the annular plate, and a spring connected to one side of the inner wall of each of the two connecting frames, one end of the spring being connected to a T-shaped insert, the vertical end of the T-shaped insert penetrating through one side of the inner wall of the annular plate, and a pull rod connected to one side of the T-shaped insert, one end of the pull rod penetrating through one side of the connecting frame, and multiple limiting holes matching the T-shaped insert being opened on both sides of the outer wall of the support column.

[0006] Preferably, a disassembly assembly is provided between the two support plates and the annular plate. The disassembly assembly includes positioning blocks. The two positioning blocks are symmetrically connected to both sides of the annular plate. A positioning groove is provided on one side of the support plate relative to the positioning block. The positioning groove is interconnected with the bottom of the support plate. A screw is provided through one side of the support plate. The screw is threadedly connected to one side of the positioning block. One end of the screw is connected to a torsion plate.

[0007] Preferably, the pull rod passes through one end of the connecting frame and is connected to a pull ring.

[0008] Preferably, the vertical end of the T-shaped insert is provided with a tapered head.

[0009] Preferably, a limiting plate is connected to the top of the support column, and diagonal braces are connected between the bottom sides of the seat body and the two support plates.

[0010] Preferably, the edges of the twist plate are provided with arc grooves.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] (1) By setting a locking component, the pull rod is pulled outward, causing the pull rod to move the T-shaped plug into the inside of the connecting frame, so that one end of the T-shaped plug is disengaged from the limiting hole. During this process, the spring is compressed inside the connecting frame. Then, the ring plate is pulled up and down. After moving to the appropriate position, the pull rod is released. Under the elastic force of the spring, one end of the T-shaped plug is inserted into the limiting hole, realizing the rapid adjustment of the height of the seat body, greatly improving the adjustment efficiency of the seat, and benefiting the operator.

[0013] (2) By setting up a disassembly and assembly component, when it is necessary to separate the seat body from the support column, the twist plate is turned so that the twist plate drives the screw to rotate, so that one end of the screw is separated from the positioning block, so that the support plate is released from the limit on the ring plate, and then the support plate is pulled upward to separate the support plate from the ring plate. This realizes the separation of the support column from the seat body, which is convenient for placing and handling the seat during production and transportation, reduces the space occupied when the seat is stored, and improves the convenience of the seat locking and adjustment structure.
