Technical Field

[0001] This utility model relates to the field of rattan chair technology, specifically to an outdoor rattan chair breathable and waterproof seat cushion. Background Technology

[0002] The outdoor environment is complex and changeable, and rattan chair cushions need to withstand direct sunlight, rain, and humid air. Ordinary cushions are prone to mold, rot, and fading under these conditions, shortening their lifespan. Therefore, they need to have good waterproof and breathable properties to keep them dry and comfortable and extend their service life.

[0003] Existing devices mainly involve placing the cushion on the seat of a rattan chair. Many existing technologies resemble rattan chairs with easily removable cushions. The structure disclosed in CN220876334U includes a support plate with armrests mounted opposite each other on the upper surface of the support plate along its width. A detachable component includes two T-shaped connecting plates connected to the sides of the cushion near the armrests. The detachable component also includes mounting grooves on the inner sidewalls of the two armrests. This device, by incorporating a detachable component, allows the cushion to be stably mounted on the rattan chair during use and can be easily removed to adapt to the needs of different materials for cushions in different seasons. However, there are still areas for improvement in this device.

[0004] Existing devices mainly use a detachable structure to place the seat cushion, which makes it difficult to place the rattan seat cushion under the movable seat board in some devices. As a result, some rattan seat cushions are easily rained on and affect their use. At the same time, some devices have difficulty limiting and braking the movable seat board to ensure stable support, which reduces the working efficiency and practicality of the device. Therefore, there is an urgent need to design a breathable and waterproof outdoor rattan chair seat cushion to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a breathable and waterproof outdoor rattan chair cushion to solve the problems mentioned in the background art. The existing devices mainly use a detachable structure to place the cushion, which makes it difficult for some devices to place the rattan cushion under the movable seat board. As a result, some rattan cushions are easily rained on and affect their use. At the same time, some devices have difficulty limiting and braking the movable seat board to facilitate stable support of the movable seat board.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an outdoor rattan chair breathable and waterproof seat cushion, including a seat frame, a chair back fixedly connected to the top right side of the seat frame, chair legs fixedly connected to the four bottom corners of the seat frame, a movable seat board movably connected to the rear side of the inner wall of the seat frame, a rattan seat cushion fixedly connected to the bottom of the movable seat board, a transmission box fixedly connected to the middle of the front side of the seat frame, and a fixing frame fixedly connected to the right side of the seat frame;

[0012] Preferably, the outer wall of the push bolt is threaded with a fixing nut, and the left side of the fixing nut is fixedly connected to the middle right side of the fixing frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This outdoor rattan chair's breathable and waterproof seat cushion utilizes a flipping mechanism consisting of a transmission worm gear, a first torsion cover, a transmission worm wheel, a transmission shaft, a main gear, an internal gear, a rotating disk, and a rotating shaft. Rotating the first torsion cover causes the transmission worm gear to rotate to a limit position. The transmission worm gear meshes with the transmission worm wheel, transmission shaft, and main gear, which in turn mesh with the main gear, causing the internal gear and rotating disk to rotate synchronously. The rotating disk then drives the rotating shaft and the movable seat plate to rotate to a limit position, thus flipping the movable seat plate. This allows some parts of the device to place the rattan seat cushion under the movable seat plate, effectively preventing the rattan seat cushion from getting wet and affecting its use, thus improving the device's protective and practical functions.

[0015] This outdoor rattan chair's breathable and waterproof seat cushion utilizes a limiting mechanism consisting of a sleeve, a push bolt, a second twist cap, and a fixing nut. By rotating the second twist cap clockwise, the push bolt is limited to rotate. The push bolt, restricted by the fixing nut, causes the sleeve to slide to the left, allowing the sleeve to fit onto the right side of the movable seat. This achieves a limiting brake on the movable seat, enabling partial braking of the movable seat and facilitating stable support, thus improving the stability and practicality of the device.
