Technical Field
[0001] This utility model relates to the field of seating technology, specifically to a reclining chair with adjustable tilt angle. Background Technology
[0002] The materials available for lounge chairs are diverse, mainly including wood, metal, plastic, leather, and fabric. Wood, due to its natural, environmentally friendly, and durable properties, is often used to make chair frames and armrests. Metal, due to its high strength, light weight, and ease of processing, is often used to make the supporting structure of chairs. Plastic materials have the advantages of low cost, easy molding, and rich colors, making them suitable for making lounge chairs of various shapes. Leather and fabric are often used to cover the seat and backrest, providing a soft and comfortable touch.
[0003] In existing technology, park benches have a relatively simple structure, typically consisting of a seat, backrest, armrests, and legs. However, these benches cannot be personalized to suit a user's body type, posture, or physical needs. This may cause discomfort for some users after prolonged use, affecting their quality of rest. Utility Model Content

The adjustment component includes a guide slide rail installed at the top of the bracket, a slider slidably connected inside the guide slide rail, a lead screw connected to the inner wall of the slider, an armrest fixedly connected to the end of the lead screw away from the slider, connecting rods rotatably connected to both sides of the outer wall of the slider, mounting blocks rotatably connected to the ends of the two connecting rods away from the slider, push plates installed on the opposite sides of the two mounting blocks, and the bottom ends of the two mounting blocks fixedly connected to one top side of the seat cushion.
[0006] Furthermore, the surface of the handrail is integrally molded with anti-slip particles, each particle measuring one to three millimeters in size.
[0007] Furthermore, a rotating shaft is installed on the inner wall of the backrest near the bottom, and support arms are installed at both ends of the rotating shaft.
[0008] Furthermore, the rotating shaft and the support arm are fixedly connected, while the outer wall of the rotating shaft and the inner wall of the backrest are rotatably connected.
[0009] Furthermore, each support arm is equipped with a leg at its bottom, the leg being arc-shaped. Two reinforcing support columns are installed on one side of the bottom of the bracket, and each reinforcing support column is equipped with an anti-slip pad at its bottom.
[0010] Furthermore, the outer wall of the slider is provided with a groove, and the inner wall of the groove is provided with a thread. The slider is connected to the outer wall of the lead screw by the thread on the inner wall.
[0011] Furthermore, a backrest is installed on one side of the outer wall of the push plate, and the backrest is fixedly connected to the outer wall of the opposite side of the push plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are: by using the lead screw in the adjustment component for rotational adjustment, the backrest angle can be finely adjusted, and the lead screw can maintain high stability during or after adjustment, preventing accidental movement or shaking during use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution for a reclining chair with an adjustable tilt angle:
[0021] In the embodiments of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 4The system includes a seat cushion 1, which serves as the foundation of the component and is located near the bottom of the structure. To provide a comfortable user experience, a support frame 2 is installed on one outer wall of the seat cushion 1. Two reinforcing support columns are installed on one side of the bottom of the support frame 2, and each reinforcing support column has an anti-slip pad at its bottom. The reinforcing support columns enhance the structural stability of the component, ensuring that the seat will not tip over when the user adjusts the recline after sitting down. The anti-slip pads also effectively prevent the component from sliding in wet or slippery environments. An adjustment component is installed at the top of the support frame 2. The adjustment component includes a guide rail 3 installed at the top of the support frame 2. A slider 4 is slidably connected inside the guide rail 3, providing a sliding track for the slider 4 and ensuring that the slider 4 can move horizontally. A lead screw 5 is connected to the inner wall of the slider 4, and a groove is opened on the outer wall of the slider 4. The inner wall of the groove is threaded. The slider 4 is threadedly connected to the outer wall of the lead screw 5 through the thread on the inner wall. The threaded connection has higher stability and can resist larger axial and radial forces, ensuring that the slider 4 will not loosen due to force during movement or stabilization. The screw rod 5, located away from the slider 4, is fixedly connected to an armrest 6. Users can easily move the slider 4 horizontally along the inner wall of the guide rail 3 by rotating the armrest 6. The armrest 6 has integrally formed anti-slip particles, each ranging from one to three millimeters in size. These particles increase friction between the armrest 6 and the user's hand, preventing slippage in wet or sweaty conditions and improving user safety. To prevent hand slippage and external injury, connecting rods 7 are rotatably connected to both sides of the outer wall of the slider 4. Mounting blocks 8 are rotatably connected to the ends of the two connecting rods 7 away from the slider 4. Push plates 9 are installed on the opposite sides of the two mounting blocks 8. The connecting rods 7 can convert the movement of the slider 4 into the tilting movement of the push plates 9. The bottom ends of the two mounting blocks 8 are fixedly connected to the top side of the seat cushion 1 to ensure the stability of the component. The push plates 9 are linked with the slider 4 through the transmission of the connecting rods 7, thereby pushing the backrest 10 to achieve the angle adjustment of the backrest 10.
[0022] participate Figure 1 , Figure 2 , Figure 3 , Figure 4 A backrest 10 is installed on one side of the outer wall of the push plate 9. The backrest 10 is fixedly connected to the outer wall of the push plate 9 on the opposite side. A rotating shaft 11 is installed on the inner wall of the backrest 10 near the bottom. Support arms 12 are installed at both ends of the rotating shaft 11. The rotating shaft 11 allows the backrest 10 to rotate and adjust around the support arms 12. The angle adjustment meets the needs of different users for sitting comfort.
[0023] Working principle: When the user rotates the armrest 6, it drives the lead screw 5 to rotate synchronously. Because the outer wall of the lead screw 5 is rotatably connected to the inner wall of the guide rail 3, the lead screw 5 will not move on the outer wall of the guide rail 3 after rotating. However, the slider 4, which is threaded to the outer wall of the lead screw 5, will move on the inner wall of the guide rail 3 according to the rotation of the lead screw 5. After the lead screw 5 drives the slider 4 to move, the slider 4 pulls the mounting block 8 to drive the push plate 9 to tilt around the mounting block 8, thereby realizing the angle adjustment of the backrest 10 around the rotating shaft 11, meeting the needs of different users for the tilt of the chair, and enhancing the adaptability of the components.
