Connecting rod 111 and lower link 112, then coordinate the desktop for being capable of achieving that angle is zero degree by adjusting support 12 and teeth 13.
Drawing teaching state as shown in Figure 3, after desktop 1 rises, is fixed by spine tooth rotating shaft mechanism 15 first
With the cooperation of teeth 13, connecting rod 111 and lower link 112, then realize that 1 front end of desktop is downward-sloping by adjusting support 12, with water
Horizontal line angle is 5 °～10 °.
Drawing teaching state as shown in Figure 4, after desktop 1 rises, adjusts the angle of upper connecting rod 111, by spine
Tooth rotating shaft mechanism 15 fixes upper connecting rod 111 and lower link 112, does not use adjustment support 12 to be supported, directly make desktop 1 with
Connecting rod 3 is contacted.
As shown in fig. 7, lock pin is first separated by the folding shrinking process of the present invention with lock groove 24, then spine tooth is turned
Axis mechanism 15 is unlocked, and desktop 1 is adjusted support 12 and is put down, put down naturally desktop, enables locking device 16 afterwards real
The locking of existing desktop 1 and base plate relative position, you can pack up or carry.
The function such as theory teaching study, various mechanical drawing teachings, various drawing teaching is integrated in one by the present invention, is made
One tables and chairs is provided simultaneously with multiple classroom and uses function, disclosure satisfy that various use demands of existing teaching, and according to difference
Human body adjustment meets the condition of the ergonomics of oneself, picks up good habits of study, and is conducive to that user's is healthy
Grow up, meanwhile, the present invention can also aid in correcting the student of bad study habit, correction sitting posture etc.；Can be according to user
The current desired use position wanted, desktop angle oneself adjustment, adjustment are simple, easy to operate；Not only in material using section
About, simple structure, and being substantially reduced in the space put, it is conveniently laying, packed up using can fold after finishing, even more can
The service efficiency of enough effective rooms for promotion, is an economizing type design, meanwhile, present configuration is simply cheap, to big
Many schools can set up, and the teaching of its multifunction, multi-functional usability are practical, it might even be possible to be applied to
The occasions such as office, equally with superiority, the field such as batch application to teaching, office, its cost further can reduce, Er Qieben
Invention is transported after folding, it is also possible to significantly relatively low cost of transportation, easy to utilize.
