[0034] The fixing mechanism 6 includes a fixing member 62, which is used to fix the first support member 22.

[0035] The first support mechanism 2 supports students' legs during learning activities and lunch breaks. The rotating component 21 is L-shaped and can be made of stainless steel, aluminum alloy, or cast iron, preferably stainless steel. One end of the rotating component 21 is rotatably connected to the surface of one end of the chair 1. The first support component 22 is rotatably mounted on the top section of the rotating component 21. The first support component 22 can be made of solid wood, engineered wood, or plastic, preferably plastic. One end of the first push-pull component 23 is rotatably connected to the surface of the rotating component 21. The second support mechanism 3 supports the student's back. Both ends of the second support component 31 are rotatably connected to the rear end of the chair 1, and the connecting ends can be metal. The second support component 31 can be made of solid wood, engineered wood, or plastic, preferably solid wood. The first connecting component 32 can be made of stainless steel, cast iron, or aluminum alloy. The first support member 22 is fixedly connected to the bottom of the second support member 31. The reinforcement mechanism 4 is used to support and reinforce the first support member 22. The reinforcement member 42 is U-shaped and can be made of solid wood, plastic, stainless steel, etc., preferably solid wood. The adjustment mechanism 5 is used to adjust the angle of the rotating member 21 and the second support member 31, as well as the position of the reinforcement member 42. The main transmission member 51 can be a threaded rod, an electric telescopic rod, or a hydraulic cylinder, etc., preferably a threaded rod. The two ends of the third connecting member 53 are fixedly connected to the two ends of the reinforcement member 42, so that when the main transmission member 51 rotates, the auxiliary transmission member 52 can drive one end of the reinforcement member 42 and the second push-pull member 33 to move to the front end. The fixing mechanism 6 is used to fix the first support member 22. The fixing member 62 can be a bolt, a spring pin, or a buckle, etc., preferably a spring pin.

[0036] The bottom of the second support member 31 is connected to a first connector 32, and the surface of the first connector 32 is connected to a second push-pull member 33. The second push-pull member 33 is used to connect and transmit power with the first connector 32 and the third connector 53 to realize the rotation of the second support member 31.

[0037] There are two of each of the first connector 32 and the second push-pull member 33. They can be made of stainless steel, cast iron, aluminum alloy, etc., preferably stainless steel. The two first connectors 32 are fixedly connected to the bottom of the second support member 31. One end of the two second push-pull members 33 is rotatably connected to the surface of the two first connectors 32, and the other end is rotatably connected to the surface of the third connector 53.

[0038] The bottom of the chair 1 is connected to a limiting member 41, and a second connecting member 43 is connected to one end of the surface of the reinforcing member 42. The limiting member 41 is used to support and limit the reinforcing member 42, and the second connecting member 43 is used to connect with the reinforcing member 42 and the first push-pull member 23 to realize transmission.

[0039] The limiting member 41 can be a slide rail, slide rod, or slide groove, preferably a slide rail. The two ends of the reinforcing member 42 are slidably connected inside the slide rail. The second connecting member 43 is rotatably connected to the other end of the first push-pull member 23 through the surface of one of the limiting members 41. Thus, when the reinforcing member 42 moves, one end of the first push-pull member 23 can be moved through the second connecting member 43.

[0040] One end of the main transmission component 51 is connected to a secondary transmission component 52. An adjusting component 54 is connected to the surface of the secondary transmission component 52. The secondary transmission component 52 is used to drive the movement of the main transmission component 51, and the adjusting component 54 is used to facilitate operation to achieve the movement of the main transmission component 51.

[0041] The secondary transmission component 52 can be a bevel gear, belt, or worm gear, preferably a bevel gear. The two bevel gears in the secondary transmission component 52 are fixedly connected to the front end of the main transmission component 51 and the top of the adjusting component 54, respectively. By rotating the adjusting component 54, the two bevel gears mesh, which can drive the main transmission component 51 to rotate.

[0042] The surface of the first support member 22 is connected to a fixing plate 61 and a fixing hole 63, which are used for connection and fixation.

[0043] The fixing plate 61 is fixedly connected to the other end of the rotating member 21. The surface of the first support member 22 is provided with two fixing holes 63. By embedding the fixing member 62 into the different fixing holes 63, the first support member 22 can be fixed with different faces facing upwards.

[0044] The working principle of the lunch break desk and chair with a folding structure provided by this utility model is as follows:

[0045] When a rest is needed, first pull the fixing member 62 outward so that one end is disengaged from the fixing hole 63. Then rotate the first support member 22 until the bottom is facing upward. Then release the fixing member 62, and one end is inserted into the fixing hole 63, thus fixing the first support member 22. Next, hold the adjusting member 54 and rotate it. The auxiliary transmission member 52 drives the main transmission member 51 to move. The third connecting member 53 drives the reinforcing member 42 and one end of the two second push-pull members 33 to move towards the front end. At the same time, the reinforcing member 42 drives one end of the first push-pull member 23 to move towards the front end. As the first push-pull member 23 moves, its angle changes, pushing the rotating member 21 to rotate the first support member 22 downwards. The other end of the second push-pull member 33 pulls the first connecting member 32 to rotate the second support member 31 to the rear end until the first support member 22 rotates to the same horizontal line as the top of the chair 1 and the bottom is connected to the top of the reinforcement member 42. The second support member 31 then rotates to a suitable angle, and finally the student can lie on the second support member 31 with their back and waist, and rest their legs on the first support member 22.

[0046] Compared with related technologies, the lunch break desk and chair with a folding structure provided by this utility model has the following beneficial effects:

[0047] This utility model provides a lunch break desk and chair with a folding structure. By adjusting the mechanism 5 and the transmission of the first push-pull member 23 and the second push-pull member 33, the rotating member 21 can be rotated to a suitable angle and the second support member 31 can be rotated to be level with the top of the chair 1. The first support member 22 and the fixing mechanism 6 are used to fix it. Students can lie on the chair, which provides support for their back and legs and is beneficial to the development of their spine and bones.
