Description

Technical Field

[0001] The invention relates to the technical field of desks and chairs, in particular to a desk and chair for students during lunch break to prevent them from catching a cold. Background Art

[0002] Desks and chairs are a combination of tables and chairs used exclusively by students in class, also known as student desks and chairs. They can be divided into kindergartens, primary schools, middle schools, and universities according to the user groups. They have functions ranging from fixed to liftable, and materials include wood, plastic, and a mixture of wood and steel. At present, naps are essential for teenagers, and in some limited classroom environments, students can only sleep on their stomachs. However, desks and chairs for student lunch breaks are made of rigid wood or metal structures, and the tabletops are flat. Therefore, students have significant defects during their winter lunch breaks: traditional desks and chairs for lunch breaks leave their abdomens suspended in the air when they sleep on their stomachs, so cold wind blows directly from doors and windows, which can easily lead to gastrointestinal discomfort. In addition, when sleeping on their stomachs, the waist is forced to bend due to lack of support, causing strain. Summary of the Invention

[0012] Preferably, the side panel shell slides through the inner side of the receiving opening, and the damping shaft provides a damping effect at the connection between the side panel shell and the movable bar.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Pull out the insulation cloth and the abdominal support plate from the inner side of the table until the abdominal support plate and the connecting shaft are moved out of the first storage cavity, rotate the abdominal support plate and the connecting shaft downward along the connecting shaft block, and then rotate the V-shaped support bar and the support rod along the round rod and move them out of the inside of the square groove. At the same time, twist the rotating torsion spring to support the V-shaped support bar at the edge of the table pocket. The insulation cloth and square memory foam on the abdominal support plate can support the abdomen of the student lying on the table, and the square memory foam provides flexible support to the abdomen, and the insulation cloth keeps the student's abdomen warm to prevent the abdomen from catching cold. The square Velcro on the insulation cloth is convenient for removing and cleaning the insulation cloth, and the twisting rotating torsion spring facilitates the subsequent automatic retraction of the V-shaped support bar and support rod.

[0015] 2. The fixed rope drums on both sides rotate along the round rod, driving the fixed rope drums on both sides and the four sets of side panel pull ropes to be pulled. The four sets of side panel pull ropes respectively pull the four connected rotating side panels. The four sets of rotating side panels on both sides are rolled up toward the middle abdominal support plate, forming an arc shape that wraps around the two sides of the abdomen, providing side shielding and support for the abdomen of students taking lunch break, increasing protection and warmth for students during lunch break, and improving the comfort of lunch break.

[0016] 3. While the square frame is moving, the fixed shafts on both sides slide along the movable opening, and the two sets of first circular shafts push the connected push rods and second circular shafts respectively, so that the movable bar and the side panel shell are automatically moved out from the second storage cavity and the inside of the storage opening. After the side panel shell is completely moved out, the side panel shell is rotated upward, and the damping shaft is used to make the side panel shell stand upright. Pulling out the inner panel from the inside can increase the height of the side panel shell side guard, shielding the head of the student lying on the table, reducing the side cold wind blowing directly to the student's head, preventing the cold wind from irritating the face and ears, and improving the overall sleep quality.

[0039] While the square frame 32 moves, the fixed shafts 45 on both sides slide along the movable opening 44, and the two groups of first circular shafts 46 push the connected push rods 49 and second circular shafts 48 respectively, so that the movable bar 47 and the side panel shell 410 are automatically moved out from the second storage cavity 41 and the inner side of the storage opening 42. After the side panel shell 410 is moved out, the side panel shell 410 is rotated upward, and the damping shaft 411 is used to make the side panel shell 410 stand upright, and the inner side panel 412 is pulled out from the inside to increase the height of the side guard of the side panel shell 410, thereby shielding the head of the student lying on the table 1, reducing the side cold wind from blowing directly onto the student's head, preventing the cold wind from irritating the face and ears, and improving the overall sleep quality.

[0040] Working principle: During lunch break, pull out the insulation cloth 37 and the abdominal support plate 36 from the inner side of the table 1 until the abdominal support plate 36 and the connecting shaft 35 are moved out of the first storage cavity 31, and then rotate the abdominal support plate 36 and the connecting shaft 35 downward along the connecting shaft block 33, and then rotate the V-shaped support bar 313 and the support rod 312 along the round rod 311 and move out of the inside of the square groove 310, and twist the rotating torsion spring 314 at the same time to support the V-shaped support bar 313 at the edge of the table pocket of the table 1, and the insulation cloth on the abdominal support plate 36 is 37. The square memory foam 38 can support the abdomen of the student lying on the table 1, and the square memory foam 38 provides flexible support for the abdomen, and the thermal insulation cloth 37 keeps the student's abdomen warm to prevent the abdomen from catching cold. The square Velcro 39 set on the thermal insulation cloth 37 is convenient for removing and cleaning the thermal insulation cloth 37, and the twisting rotating torsion spring 314 facilitates the subsequent automatic retraction of the V-shaped support bar 313 and the support rod 312; at the same time, the fixed rope drums 317 on both sides rotate along the round rod 311, driving the fixed rope drums 317 on both sides to rotate with the fixed rope drums 317 and the fixed rope drums 317 on both sides. The four sets of side panel pull ropes 318 connected in a fixed manner are pulled, and the four sets of side panel pull ropes 318 respectively pull the four sets of connected rotating side panels 315, and the four sets of rotating side panels 315 on both sides are retracted toward the middle abdomen support plate 36, forming an arc-shaped state wrapped around the positions on both sides of the abdomen, providing side shielding and support for the abdomen of students taking lunch break, increasing the protection and warmth of students taking lunch break, and improving the comfort of lunch break; in addition, while the square frame 32 moves, the fixed shafts 45 on both sides slide along the movable opening 44, and the two sets of first circular shafts 46 respectively push the connected push shafts The rod 49 and the second circular shaft 48 make the movable bar 47 and the side panel shell 410 automatically move out from the inside of the second storage cavity 41 and the storage port 42. After the side panel shell 410 is completely moved out, the side panel shell 410 is rotated upward, and the damping shaft 411 is used to make the side panel shell 410 stand upright. The inner panel 412 is pulled out from the inside to increase the height of the side guard of the side panel shell 410, thereby shielding the head of the student lying on the table 1, reducing the side cold wind from blowing directly to the student's head, preventing the cold wind from irritating the face and ears, and improving the overall sleep quality.
