Abstract
Description
Technical Field
[0001] This utility model relates to the field of folding chair technology, and in particular to an outdoor folding chair with high compressive strength. Background Technology
[0002] An outdoor folding chair is a foldable chair designed specifically for outdoor activities, typically used for camping, fishing, picnics, beaches, and other similar occasions. Outdoor folding chairs are usually lightweight, easy to fold, convenient to carry and store, and made of wear-resistant and weather-resistant materials that can withstand the test of outdoor environments. The support legs of outdoor folding chairs are usually made of metal, which has a certain degree of strength, but there are still problems that need to be solved.
[0003] In most existing outdoor folding chairs, when unfolded, there is a certain angle between the two support legs. When a heavier user sits on the chair, the angle between the two support legs may increase further. The support legs and connecting parts of the chair may be subjected to excessive pressure, causing material fatigue or breakage. The chair may then be at risk of breaking, resulting in a poor user experience. Therefore, it is necessary to design an outdoor folding chair with high compressive strength to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an outdoor folding chair with high compressive strength.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-compression-strength outdoor folding chair includes a chair body. Two support legs are provided on each side of the chair body. The two support legs on the same side are respectively fixedly connected to a first fixing plate and a second fixing plate. A fixing shaft is fixedly connected to one side of the first fixing plate. A sleeve is fitted onto the fixing shaft, and the sleeve is rotatably connected to the fixing shaft. A first reinforcing rod is fixedly connected to the outer wall of the sleeve. A locking block is fixedly connected to one side of the first reinforcing rod. A limiting shaft is fixedly connected to one side of the second fixing plate. The locking block has a slot adapted to the limiting shaft. A fixing seat is fixedly connected to the outer wall of the support leg near the first fixing plate. Two rotating shafts are rotatably connected to the fixing seat. The two rotating shafts are fixedly connected to the same second reinforcing rod. A sleeve plate is fitted onto the top of the second reinforcing rod. Both sleeve plates are fixedly connected to the chair body. Due to the use of the first reinforcing rod, locking block, and second reinforcing rod... The technology of using reinforcing bars to improve support and connection strength allows for several advantages. First, the reinforcing bar limits the opening angle between the two support legs when a heavier user sits on the chair, preventing damage due to excessive opening angle. Second, the reinforcing bar increases support strength and prevents the seat cushion from collapsing. This effectively solves the problem mentioned in the background section of existing outdoor folding chairs where, after unfolding, there is an angle between the two support legs. When a heavier user sits on the chair, this angle may increase further, potentially causing excessive pressure on the support legs and connections, leading to material fatigue or breakage, and ultimately, chair collapse and a poor user experience. This technology significantly improves safety, effectively prevents collapse when a heavier user sits on the chair, enhances overall load-bearing capacity, and improves the chair's lifespan and performance.
[0007] As a further embodiment of this utility model, the first reinforcing rod is provided with a first insertion hole, and the second reinforcing rod is provided with a second insertion hole.
[0008] As a further embodiment of this utility model, an L-shaped plate is fixedly connected to the outer wall of the support leg near the second socket. A handle is provided on one side of the L-shaped plate, and square plates are fixedly connected to both sides of the handle. A first pin and a second pin are fixedly connected to the same side of the two square plates respectively. The first pin is adapted to the second socket, and the second pin is adapted to the first socket.
[0009] As a further embodiment of this utility model, two fixed rods are fixedly connected to one side of the handle, and the two fixed rods are fixedly connected to the same movable plate.
[0010] As a further embodiment of this utility model, guide rods are provided at both ends of the movable plate, the movable plate is slidably connected to the guide rods, and the guide rods are fixedly connected to the L-shaped plate.
[0011] As a further embodiment of this utility model, the guide rod is fitted with a return spring, which is disposed between the moving plate and the handle.
[0012] The beneficial effects of this utility model are as follows:
[0013] By employing a first reinforcing rod, a locking block, and a second reinforcing rod to enhance support and connection strength, the first reinforcing rod limits the opening angle between the two support legs when a heavier user sits on the chair, preventing damage due to excessive opening angle. The second reinforcing rod increases support strength and prevents the seat cushion from collapsing. This effectively solves the problem mentioned in the background art where, in most existing outdoor folding chairs, there is an angle between the two support legs after unfolding. When a heavier user sits on the chair, this angle may further increase, potentially causing excessive pressure on the support legs and connections, leading to material fatigue or breakage, and the risk of the chair collapsing, resulting in a poor user experience. This significantly improves safety, effectively prevents collapse when a heavier user sits on the chair, enhances overall load-bearing capacity, and improves the chair's lifespan and performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-5 A high-compression-strength outdoor folding chair includes a folding chair body 1. Two support legs 101 are provided on both sides of the folding chair body 1. The two support legs 101 on the same side are respectively fixedly connected to a first fixing plate 2 and a second fixing plate 7. A fixing shaft 3 is fixedly connected to one side of the first fixing plate 2. A sleeve 4 is fitted onto the fixing shaft 3, and the sleeve 4 is rotatably connected to the fixing shaft 3. A first reinforcing rod 5 is fixedly connected to the outer wall of the sleeve 4. A locking block 6 is fixedly connected to one side of the first reinforcing rod 5. A limiting shaft 8 is fixedly connected to one side of the second fixing plate 7. The locking block 6 has a slot adapted to the limiting shaft 8. A fixing seat 9 is fixedly connected to the outer wall of the support leg 101 near the first fixing plate 2. Two rotating shafts 10 are rotatably connected to the fixing seat 9. The two rotating shafts 10 are fixedly connected to the same second reinforcing rod 11. A sleeve plate 12 is fitted onto the top of the second reinforcing rod 11. Both sleeve plates 12 are fixedly connected to the folding chair body 1. Due to the use of the first reinforcing rod 101... The technical means of using a strong rod, a locking block, and a second reinforcing rod to improve support and connection strength allows the first reinforcing rod to limit the opening angle between the two support legs when a heavier user sits on the chair, preventing damage due to excessive opening angle. The second reinforcing rod increases support strength and prevents the seat cushion from collapsing. This effectively solves the problem mentioned in the background art that in most existing outdoor folding chairs, after unfolding, there is a certain angle between the two support legs. When a heavier user sits on the chair, this angle may further increase, potentially causing excessive pressure on the support legs and connections, leading to material fatigue or breakage, and the risk of the chair collapsing, resulting in a poor user experience. Therefore, this technology significantly improves safety, effectively prevents collapse when a heavier user sits on the chair, improves overall load-bearing capacity, and enhances the chair's lifespan and performance.
[0022] In this embodiment, the first reinforcing rod 5 has a first insertion hole 13, and the second reinforcing rod 11 has a second insertion hole 14.
[0023] In this embodiment, an L-shaped plate 15 is fixedly connected to the outer wall of the support leg 101 near the second socket 14. A handle 18 is provided on one side of the L-shaped plate 15, and square plates 19 are fixedly connected to both sides of the handle 18. A first pin 20 and a second pin 21 are fixedly connected to the same side of the two square plates 19, respectively. The first pin 20 is adapted to the second socket 14, and the second pin 21 is adapted to the first socket 13. By inserting the second pin 21 into the first socket 13 and the first pin 20 into the second socket 14, the angle of the first socket 13 and the second socket 14 can be restricted. When the chair is folded and transported, the first socket 13 and the second socket 14 will not unfold, making it easy to transport.
[0024] In this embodiment, two fixed rods 17 are fixedly connected to one side of the handle 18, and the two fixed rods 17 are fixedly connected to the same movable plate 16.
[0025] In this embodiment, guide rods 22 are provided at both ends of the movable plate 16. The movable plate 16 is slidably connected to the guide rods 22, and the guide rods 22 are fixedly connected to the L-shaped plate 15. When the movable plate 16 moves, it will move along the guide rods 22 to ensure the stability of the movable plate 16 during movement, and also to enable the first pin 20 and the second pin 21 to move in a straight line stably.
[0026] In this embodiment, the guide rod 22 is fitted with a reset spring 23, which is located between the moving plate 16 and the handle 18. By setting the reset spring 23, the moving plate 16 can be reset without external force due to the elastic force of the reset spring 23.
[0027] Working principle: When the chair is unfolded, pulling handle 18 moves it, which in turn moves square plate 19. Square plate 19 then moves first pin 20 and second pin 21. Removing first pin 20 from second insertion hole 14 and second pin 21 from first insertion hole 13 releases the restriction on first reinforcing rod 5 and second reinforcing rod 11. Unfolding first and second reinforcing rods 5 and 11, rotating first reinforcing rod 5 moves locking block 6, which then engages with limiting shaft 8. Rotating second reinforcing rod 11 moves the end away from fixed seat 9 into sleeve plate 12. When the user sits on the folding chair body 1, the bottom ends of the two support legs 101 move away from each other, but the movement distance is limited by first reinforcing rod 5. Therefore, when a heavier user sits on the chair, damage caused by excessive opening angle of the two support legs 101 can be avoided. Furthermore, when the seat cushion of the folding chair body 1 is under pressure, it will cause the sleeve plate 12 to... As the chair descends, the sleeve 12 is supported by the second insertion hole 14, preventing the seat cushion from collapsing. Under gravity, the locking block 6 remains locked on the limiting shaft 8, preventing it from falling off. When the chair needs to be folded, the second reinforcing rod 11 is removed from the sleeve 12, and the locking block 6 is removed from the limiting shaft 8. Pulling the handle 18 again moves the first pin 20 and the second pin 21. During this process, the handle 18 moves the fixing rod 17, which in turn moves the moving plate 16. The moving plate 16 moves along the guide rod 22 and compresses the return spring 23, causing it to contract. This causes the first reinforcing rod 5 and the second reinforcing rod 11 to rotate until they are parallel to the support leg 101. Releasing the handle 18 allows the first pin 20 to be inserted into the second insertion hole 14 and the second pin 21 to be inserted into the first insertion hole 13. This restricts the angle of the first reinforcing rod 5 and the second reinforcing rod 11, preventing them from changing angle and unfolding during transport, thus facilitating handling.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
