[0025] 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.

[0026] Please see Figure 1-8As shown, a folding chair with easy ventilation includes a frame 1 and a seat 2. The seat 2 is hinged to the surface of the frame 1. The surface of the frame 1 has a sloping groove 3. A connecting frame 4 is fixedly connected to the surface of the seat 2. The surface of the connecting frame 4 contacts the inner wall of the sloping groove 3. The position of the seat 2 can be easily restricted by the cooperation of the sloping groove 3 and the connecting frame 4. This is a mature existing technology and will not be described in detail here. A ventilation groove 5 is provided at the top of the seat 2, and a sliding groove is provided at the bottom of the seat 2. A horizontal crossbar is slidably connected to the inner wall of the sliding groove. The plate 7 has guide grooves 6 on both sides of its inner wall. Guide rods 8 are fixedly connected to the surfaces of both sides of the plate 7. The surfaces of the guide rods 8 are in contact with the inner walls of the guide grooves 6. The cooperation between the guide rods 8 and the guide grooves 6 guides and limits the movement of the plate 7. A support plate 17 is fixedly connected to the bottom of the inner wall of the slide. The top of the support plate 17 is in contact with the bottom of the plate 7. The support plate 17 restricts the position of the plate 7 after it is stored. A slot 9 is provided at the bottom of the plate 7. Both sides of the wall have cylindrical grooves 10, and short columns 11 are rotatably connected to the inner walls of the cylindrical grooves 10. One end of the short column 11 is fixedly connected to a mounting plate 12. The surface of the mounting plate 12 is in contact with the inner wall of the groove 9. A fan 13 is embedded in the surface of the mounting plate 12. After the fan 13 is started, it can drive airflow to increase the heat dissipation effect. The top of the horizontal plate 7 has a slot 14 and a cavity. A locking plate 15 is hinged to the inner wall of one side of the slot 14. The locking plate 15 facilitates the support of the rotating mounting plate 12. The length of the support plate 15 is equal to the length of the horizontal plate 7. A limiting mechanism 16 is installed inside the cavity. The limiting mechanism 16 can restrict the position of the support plate 15 to increase the stability of the support plate 15. A storage groove 18 is opened on the top of the mounting plate 12. A first positioning groove 19 and a second positioning groove 20 are respectively opened on the bottom of the inner wall of the storage groove 18 and the surface of the base plate 2. A protective mechanism 21 is installed inside the storage groove 18. A groove is opened on the surface of the protective mechanism 21. A positioning mechanism 22 is set inside the groove.

[0027] It should be noted that when the folding chair is not in use, the seat plate 2 can rotate with the adjustment of the support 1. At this time, the second positioning groove 20 faces upward, which makes it easy for the horizontal plate 7 to be stably placed inside the slide under the action of gravity. When the support 1 is unfolded, the seat plate 2 rotates in the opposite direction and is parallel to the ground. At this time, the horizontal plate 7 can be stably placed inside the slide under the action of friction, ready for subsequent use.

[0028] The limiting mechanism 16 includes an arc-shaped plate 161, a limiting rod 162, and a movable plate 163. The arc-shaped plate 161 is slidably connected to the inner wall of the cavity. The limiting rod 162 and the movable plate 163 are respectively fixedly connected to the surface and top of the arc-shaped plate 161. A first tension spring 164 is sleeved on the surface of the limiting rod 162. The limiting rod 162 slides through the surface of the clamping plate 15. Under the action of the elastic force of the first tension spring 164, the limiting rod 162 passes through the clamping plate 15 and fixes the position of the clamping plate 15. When the user rotates the clamping plate 15, he can first pull the movable plate 163 to move the arc-shaped plate 161, thereby releasing the limiting rod 162 from limiting the clamping plate 15.

[0029] The protective mechanism 21 includes a rotating shaft 211, a protective net 212, and a fixing plate 213. The two ends of the rotating shaft 211 rotate through both sides of the inner wall of the storage slot 18. The protective net 212 is wound around the surface of the rotating shaft 211 by a spring. The fixing plate 213 is fixedly connected to the protective net 212. A groove is formed on the surface of the fixing plate 213. When the user pulls the fixing plate 213, the protective net 212 unfolds. The user can limit the unfolded protective net 212 by the cooperation between the positioning mechanism 22 and the second positioning groove 20. Accordingly, the fan 13 can be blocked by the protective net 212 to increase the safety of the structure during use. After the contact between the positioning mechanism 22 and the second positioning groove 20 is released, the protective net 212 can be rewound around the surface of the rotating shaft 211 under the action of the spring.

[0030] The positioning mechanism 22 includes a smooth rod 221, a positioning plate 222, and a second tension spring 223. The two ends of the smooth rod 221 are fixedly connected to the two sides of the inner wall of the groove, respectively. There are two positioning plates 222 and two second tension springs 223. The two positioning plates 222 are slidably sleeved on the two sides of the surface of the smooth rod 221, and the second tension springs 223 are sleeved on the surface of the smooth rod 221. The surface of the positioning plate 222 is in contact with the inner walls of the first positioning groove 19 and the second positioning groove 20. When the user moves the positioning plate 222, the second tension spring 223 is stretched under force. When the protective mechanism 21 is idle, the surface of the positioning plate 222 is in contact with the inner wall of the first positioning groove 19. When the protective mechanism 21 is in use, the positioning plate 222 is in contact with the inner wall of the second positioning groove 20. Under the action of the elastic force of the second tension spring 223, the position of the positioning plate 222 can be restricted.

[0031] Working principle: In hot weather, the user can pull the horizontal plate 7 to move it outward, thereby removing the obstruction of the ventilation slot 5 by the horizontal plate 7, so that air at the bottom of the seat plate 2 can flow through the ventilation slot 5. Afterward, the user can pull the moving plate 163 while rotating the locking plate 15. After the locking plate 15 releases its restriction on the mounting plate 12, the user can flip the mounting plate 12 and adjust it to the desired position. Figure 2As shown in the diagram, the user can then rotate the card plate 15 in the reverse direction and limit it using the limiting mechanism 16, thereby supporting the mounting plate 12. The user can then move the positioning plate 222 and push the fixing plate 213 upwards as needed, releasing the contact between the positioning mechanism 22 and the first positioning groove 19. The user can then pull the fixing plate 213, causing the protective net 212 to unfold. Finally, the user can adjust the state of the positioning mechanism 22 and the protective mechanism 21 by connecting the positioning plate 222 to the second positioning groove 20. Figure 2 As shown, the protective net 212 is extended to its maximum extent at this time. The protective net 212 can further reinforce the position of the mounting plate 12. When in use, the protective net 212 can shield the fan 13 to reduce the possibility of the user's clothes or hair getting caught in the fan 13. After the fan 13 is adjusted with the mounting plate 12, the user can turn on the fan 13 to drive the airflow behind the user to increase the heat dissipation effect and improve the user's comfort.
