Referring to Fig. 3 to Figure 23, the utility model desk and chair, by simply propping or packing up movable protective plate or protection Frame 1-A/1-B/1-C/1-D and fixation push and pull extension board A5, overturn turnover panel 6 and push-and-pull extension board B6-1, utilize connection group Part connects or disconnects 2/3 seat, can be achieved with being switched fast for lunch break mode and the mode of attending class, and realizes the utility model study With the conversion of two kinds of functions of lunch break.Concrete operation method are as follows: firstly, packing up movable protective plate or the protection on desk and seat Frame 1-A/1-B/1-C/1-D first presses lower button 1-A-3, then lower by cross bar 1. if movable protective frame is 1-A (double column) 1-A-1 can pack up movable protective frame 1-A (double columns)；2. first being lifted if movable protective frame is 1-A (Dan Lizhu) One end rotation of stull 20 is received to pillar 1-A-2, and sunpender 19 is then rotated, and is allowed to take in cross bar 1-A-1 and by inside Magnetic patch 4 is sucked, and then presses lower button 1-A-3, then under by cross bar 1-A-1 can pack up movable protective frame 1-A (Dan Lizhu)；③ If movable protective frame is 1-B (double column), first lift bolt core 1-B-3A, then overturn cross bar B 1-B-1 to receive to sagging Play movable protective frame 1-B (double columns)；4. first lifting one end of stull 20 if movable protective frame is 1-B (Dan Lizhu) Rotation is received to pillar 1-B-2, and sunpender 19 is then rotated, and is allowed to take in cross bar 1-B-1 and is sucked by the magnetic patch of inside 4, so Movable protective frame 1-B (Dan Lizhu) can be packed up to sagging by overturning cross bar B 1-B-1 again afterwards；5. if movable protective plate or Protective frame is 1-C, first lifts drag hook 1-C-2, and then for rotor plate/frame 1-C-1 to sagging, then rotating drag hook 1-C-2 makes its hook Live in clamp 1-C-3 can pack up movable protective plate or protective frame 1-C；6. if movable protective frame is 1-D, first to spring 24 Side push-and-pull lock piece 1-D-3 lower end handle until the top strut 1-D-2 the end Ka Jiao and lock piece 1-D-3 Ka Jiao It is kept completely separate, then pushes cross bar C1-D-1 to the side of spring 24, work can be packed up by being allowed to go to the position flushed with desktop Dynamic protective frame 1-D then packs up all extension board A5 in desk and chair two sides, extension board B6-1 and extension board C12, finally turns over Turn turnover panel 6 and fix the upper end of turnover panel 6 with rotary buckle 6-2, so, the utility model desk and chair can be opened Mode of learning；, whereas if turnover panel 6 is gone to horizontal position by rotation rotary buckle 6-2 first, the student of seat is slept, it can be 2 A or 3 seats are connected together using connection component, and then, desk and chair two sides institute is unfolded according to oneself height in student Some extension board A5, extension board B6-1 and extension board C12, are pulled to suitable position, finally, erecting the activity on desk and seat Protective plate or protective frame 1-A/1-B/1-C/1-D and fixation first lifted 1. if movable protective frame is 1-A (double column) Cross bar 1-A-1 is pulled to button 1-A-3 alignment holes 116-A, pushes away in spring or (flexible) wire/piece 1-A-4 Power lower button 1-A-3 protrusion hole 116-A can erect movable protective frame 1-A (double columns) and fix；2. if movable Protective frame is 1-A (Dan Lizhu), first lifts cross bar 1-A-1, is pulled to button 1-A-3 alignment holes 116-A, in spring or (tool It is flexible) wire/piece 1-A-4 thrust lower button 1-A-3 protrusion hole 116-A, then rotate one end of sunpender 19 extremely One end rotation of upright position, stull 20 of falling is received to horizontal position, limitation of the sunpender 19 in cross bar 1-A-1 inner wall and stull 20 It is lower just relatively fixed, the movable protective frame 1-A (one-mast support) of standing can be formed in this way and is fixed；3. if movable anti- Retaining frame is 1-B (double column), first overturns column B1-B-2 and stands on above desktop, the bolt core 1-B-3A for rotating two sides is inserted it into In fork 1-B-3B, movable protective frame 1-B (double columns) can be erected and fixed；4. if movable protective frame is 1-B (Dan Lizhu) first overturns column B1-B-2 and stands on above desktop, and rotation bolt core 1-B-3A is inserted it into fork 1-B-3B, Then one end to the upright position of sunpender 19 is rotated, one end rotation for stull 20 of falling is received to horizontal position, and sunpender 19 is in cross bar It is just relatively fixed under the limitation of 1-B-1 inner wall and stull 20, the movable protective frame 1-B (Dan Li of standing can be formed in this way Column) and it is fixed；5. first lifting drag hook 1-C-2 if movable protective plate or protective frame are 1-C, then rotor plate/frame 1-C-1 To standing on above desktop, then rotation drag hook 1-C-2, which makes it hook clamp 1-C-3, can form the movable protective plate of standing Or protective frame 1-C and fixation；6. first lifting the front end cross bar C1-D-1 (has lock piece 1-D-3 if movable protective frame is 1-D One end), strut 1-D-2 rotates upwards therewith, when go to push-and-pull the end lock piece 1-D-3 the top Ka Jiao and strut 1-D-2 Card angular contact when, continue firmly to lift cross bar C1-D-1, at this time the Ka Jiao on the top strut 1-D-2 can firmly squeeze lock piece 1- The Ka Jiao of the end D-3, lock piece 1-D-3 squeeze the spring 24 being attached thereto again, until the Ka Jiao's on the top strut 1-D-2 is following Until the top for crossing the Ka Jiao of the end lock piece 1-D-3, then lock piece 1-D-3 blocks strut under the thrust of spring 24 The Ka Jiao on the top 1-D-2, due to the strut 1-D-2 below the front end cross bar C1-D-1 be locked up part 1-D-3 latching cannot be forwards It rotates, the strut 1-D-2 below the rear end cross bar C1-D-1 cannot be rotated backward by the inner wall limitation of locating groove again, therefore The movable protective frame 1-D of standing and fixation can be formed, in this way, which the utility model desk and chair can open lunch break mould Formula meets the lunch break demand of different height students.
