[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a folding multi-functional office chair. (Refer to...) Figure 1 , Figure 3 , Figure 4 and Figure 5 A folding multi-functional office chair includes a seat 1, with support legs 5 fixedly connected to the four corners of the bottom of the seat 1, and anti-slip pads 6 fixedly connected to the bottom of the support legs 5. The anti-slip pads 6 are made of rubber. A backrest 4 is provided on the top of the seat 1, and a folding mechanism 2 is installed on the back side of the seat 1.

[0025] The folding mechanism 2 includes a fixed base 202, the front of which is fixedly connected to the back of the seat 1. A movable base 203 is rotatably connected to the inner cavity of the fixed base 202. The top of the movable base 203 is fixedly connected to the bottom of the backrest 4. A connecting shaft 207 is fixedly connected to the inner cavity of the movable base 203. Ratchets 206 are fixedly connected to both sides of the surface of the connecting shaft 207, and the two ratchet wheels 206 are arranged opposite to each other. Support rods 209 are fixedly connected to both sides of the fixed base 202. Pads 216 are rotatably connected to the surface of the support rods 209. The top of the pads 216 contacts the bottom of the ratchet wheels 206. A connecting seat 212 is fixedly connected to the back of the pads 216. A rotating seat 213 is rotatably connected to the inner cavity of the connecting seat 212. A connecting rod 215 is rotatably connected to the inner cavity of the rotating seat 213. One side of the connecting rod 215 is fixed. The chair back 4 is connected to a handle 205. When the chair back 4 needs to be folded, the handle 205 is held and moved downwards. The movement of the handle 205 drives the connecting rod 215 to move, which in turn drives the rotating seat 213 to move. The movement of the rotating seat 213 drives the connecting seat 212 to move. During the movement of the rotating seat 213, it rotates both inside the connecting seat 212 and on the surface of the connecting rod 215. The movement of the connecting seat 212 drives the pawl 216 to rotate around the surface of the support rod 209. When the pawl 216 rotates downwards, it disengages from the surface of the ratchet 206, thus removing the obstruction to the ratchet 206. At this time, by holding the chair back 4 and rotating it counterclockwise, the chair back 4 can be pressed against the top of the seat 1, thereby reducing the space occupied by the chair back 4.

[0026] Reference Figure 5 A spring 210 is fixedly connected to the other side of the pawl 216. A fixing plate 211 is fixedly connected to one end of the spring 210. One side of the fixing plate 211 is fixedly connected to the surface of the fixing seat 202. The fixing plate 211 fixes the position of the spring 210 and prevents the pawl 216 from rotating too much, which would affect the normal use of the pawl 216. The spring 210 supports the position of the pawl 216. When the pawl 216 is not under force, the spring 210 can restore its deformation and drive the pawl 216 to quickly reset, so that the pawl 216 can block the position of the ratchet 206 again, ensuring the stability of the chair back 4 during use.

[0027] Reference Figure 5 A limiting ring 208 is fixedly connected to the surface of the support rod 209. One side of the limiting ring 208 is rotatably connected to the surface of the pawl 216. The limiting ring 208 is used to position the pawl 216, thereby improving the stability of the pawl 216 during use and preventing the pawl 216 from detaching from the surface of the support rod 209 during rotation, which would affect the fixing effect of the ratchet 206.

[0028] Reference Figure 2 , Figure 4 and Figure 5 Protective covers 201 are fixedly connected to both sides of the fixed base 202. The inner cavity of the protective cover 201 has a movable groove 204, and the inner cavity of the fixed base 202 has a guide groove 214. The inner cavities of the movable groove 204 and the guide groove 214 are slidably connected to the surface of the connecting rod 215. The protective cover 201 protects the surface of the ratchet 206, the pawl 216, and other parts, preventing the parts from being directly exposed to the external environment. This prevents dirt from the external environment from easily adhering to the surface of the parts, increasing the maintenance frequency and reducing the service life of the parts. The movable groove 204 guides the movement of the connecting rod 215, keeping the connecting rod 215 moving vertically and preventing the position of the connecting rod 215 from shifting during movement, which would affect the normal use of the pawl 216. The guide groove 214 supports the position of the connecting rod 215, improving the stability of the connecting rod 215 during movement, and making it easier to adjust the position of the connecting rod 215.

[0029] Reference Figure 1 and Figure 2 Support mechanisms 3 are installed on both sides of the seat 1. The support mechanism 3 includes a fixed rod 305. One side of the fixed rod 305 is fixedly connected to the surface of the seat 1. An armrest 301 is rotatably connected to the surface of the fixed rod 305. A fixing ring 304 is movably connected to one side of the armrest 301. The inner cavity of the fixing ring 304 is rotatably connected to the surface of the fixed rod 305. The fixed rod 305 supports the position of the armrest 301, allowing the armrest 301 to rotate on the surface of the fixed rod 305, thus adjusting the position of the armrest 301. When it needs to be stored, the armrest 301 can also be rotated downwards to reduce the space occupied above the seat 1. At the same time, the fixing ring 304, when fitted onto the surface of the fixed rod 305, can fix the position of the armrest 301, improving the stability of the armrest 301 during use and preventing the armrest 301 from shifting during use.

[0030] Reference Figure 2 A protective pad 302 is fixedly connected to the top of the inner cavity of the armrest 301. The protective pad 302 is made of silicone. The setting of the protective pad 302 improves the comfort of the armrest 301 when it comes into contact with the skin, and avoids the surface temperature of the armrest 301 being too low, which would irritate the skin and reduce the effectiveness of the armrest 301.

[0031] Reference Figure 2The seat 1 has positioning grooves 303 on both sides. The inner cavity of the positioning groove 303 is rotatably connected to a positioning ring 306. One side of the positioning ring 306 is fixedly connected to the surface of the armrest 301. By setting the positioning groove 303, the positioning ring 306 can rotate in the inner cavity of the seat 1, thereby positioning the rotation of the armrest 301, improving the stability of the armrest 301 during rotation, and avoiding jamming when the armrest 301 rotates.

[0032] Working principle: When the chair back 4 needs to be folded, the handle 205 is moved downwards. The movement of the handle 205 drives the connecting rod 215 to move. During movement, the connecting rod 215 slides within the movable groove 204 and the guide groove 214. The movable groove 204 guides the movement of the connecting rod 215, ensuring it moves vertically and preventing positional deviation that could affect the normal use of the pawl 216. Simultaneously, the guide groove 214 supports the position of the connecting rod 215, improving its stability and facilitating position adjustment. The movement of the connecting rod 215 drives the rotating seat 213 to move, which in turn drives the connecting seat 212. During the movement of the rotating seat 213, the connecting rod 212 slides within the movable groove 204 and the guide groove 214. The interior of the connector 212 and the surface of the connecting rod 215 rotate. The movement of the connector 212 drives the pawl 216 to rotate around the surface of the support rod 209. When the pawl 216 rotates downward, it will disengage from the surface of the ratchet 206, thus removing the obstruction to the ratchet 206. At this time, by holding the backrest 4 and rotating it counterclockwise, the backrest 4 can be pressed against the top of the seat 1, thereby reducing the space occupied by the backrest 4 and making it easier to store the seat 1. The two ratchet wheels 206 are set opposite each other. The left ratchet wheel 206 cooperates with the pawl 216 to prevent the connecting shaft 207 from rotating counterclockwise, and the right ratchet wheel 206 cooperates with the pawl 216 to prevent the connecting shaft 207 from rotating clockwise, thus keeping the connecting shaft 207 in a fixed state. The stability of the backrest 4 during use is ensured by the two ratchet wheels 206 set opposite each other.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
