Description

Technical Field

[0001] This utility model relates to the field of wooden rocking chair technology, and in particular to a gravity-balanced and stable wooden rocking chair. Background Technology

[0002] A wooden rocking chair is a type of leisure chair with a rocking structure that utilizes the user's own force to achieve a small swaying motion. When sitting in a rocking chair, the user's body can sway backward, achieving the purpose of relieving stress and relaxing the mind and body.

[0003] However, in existing wooden rocking chairs, when the user leans back, the center of gravity of the user and the chair also moves backward. If the center of gravity moves too far and crosses the fulcrum behind, it is easy to tip over backward. Therefore, a gravity-balanced and stable wooden rocking chair is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gravity-balanced and stable wooden rocking chair.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gravity-balanced and stable wooden rocking chair, including a seat plate, a leg support plate fixedly connected to one end of the seat plate, a fixed post fixedly connected to the bottom of the seat plate, a snap-fit ​​groove opened at the bottom of the fixed post, an inner sleeve block snapping into the snap-fit ​​groove, a snap-fit ​​hole opened on one side of the inner sleeve block, a counterweight block fixedly connected to the bottom of the inner sleeve block, and a snap-fit ​​structure provided on the fixed post. If the center of gravity shifts excessively, the counterweight block at the bottom of the inner sleeve block will generate a reverse torque, pulling the seat plate back to the stable area through the lever principle.

[0006] The snap-fit ​​structure includes a fixed frame fixedly connected to one side of a fixed post. A sliding rod is slidably connected through one side of the fixed frame. A handle fork is rotatably connected to one end of the sliding rod. One side of the handle fork is in contact with one side of the fixed frame. Moving the handle fork causes the sliding rod to move.

[0007] The other end of the sliding rod is fixedly connected to a snap-fit ​​post. The snap-fit ​​post is slidably connected to one side of the fixed post and is adapted to the corresponding snap-fit ​​hole. The sliding rod drives the snap-fit ​​post to move, so that the snap-fit ​​post disengages from the snap-fit ​​hole.

[0008] A return spring is fitted on the sliding rod. One end of the return spring is fixedly connected to the inside side of the fixed frame, and the other end is fixedly connected to one side of the snap-fit ​​post. Through the elastic return of the return spring, the snap-fit ​​post is pushed into the snap-fit ​​hole to snap and fix the inner sleeve block.

[0009] The other end of the seat is fixedly connected to a backrest, and a headrest is fixedly connected to one side of the backrest. When the user leans against the backrest, the headrest supports the head, improving head comfort.

[0010] The bottom of the seat is fixedly connected to four support columns. The bottom of two support columns on the same side is fixedly connected to an arc-shaped support leg. The opposite side of the two arc-shaped support legs is fixedly connected to two connecting columns. With the support of the arc-shaped support legs, it is convenient for the user to sit on the seat and rock back and forth.

[0011] The bottom of the seat plate is fixedly connected to two fixing plates. Each fixing plate has two support rods fixedly connected to one side by bolts. The upper surfaces of the two support rods on the same side are fixedly connected to armrests, allowing the user to place their arms on the armrests to improve arm comfort.

[0012] This utility model has the following beneficial effects: 1. By setting an inner sleeve block and a counterweight block, when the user sits on the seat and rocks back, the center of gravity of the person will move backward and upward. If the center of gravity moves too far, the counterweight block at the bottom of the inner sleeve block will generate a reverse torque, which will pull the seat back to the stable area through the lever principle, preventing the seat from tipping over and ensuring safety and stability during use.

[0013] 2. By setting a fixed frame, sliding rod, handle fork, locking pin, and return spring, the handle fork is moved, which drives the sliding rod to move. The sliding rod drives the locking pin to move, causing the locking pin to disengage from the locking hole and compressing the return spring. Then the inner sleeve block can be pulled out, making it convenient to replace the counterweight block with a different weight according to the user's own weight. Attached Figure Description
