When collection box 14 is stretched out in the upper end of bar 22, the rotation of box frame 13 will be enabled through, so that the upper end of balancing pole 22 retracts in through-hole 25,
Upper end to can guarantee balancing pole 22 does not influence the rotation of box frame 13 when stretching out.
The length of drive rod 30 is not less than 5 times of 29 length of pawl, and drive rod 30 and pawl 29 are about driving gear
The equal angular setting of 26 axis, can be convenient for passing through lever principle, so that the second runner 12 is rotated by lesser power, so that driving
Moving gear 26 rotates together with the second runner 12, and by pawl 29, drive rod 30 and resets shaft 28 with nutating gear 27
Continuous rotation, and then realize and use lesser power, the purpose for driving support rod 3 to rotate.
Working principle: this is carried to convenient for the adjustment height desk of categorised collection building blocks using position first, in children
When using the desk, the desk can be about to certainly and be moved to certain using position, the mode of movable desk is as follows:
Step 1: threaded rod 6 being rotated by the first runner 7, so that threaded rod 6 moves up, to drive follow block 8 to move up, in turn
Mounting rod 11 is lifted close to one end of follow block 8, the mounting rod 11 close to 8 one end of follow block is lifted, in supporting block 9 and connecting shaft 10
Under the action of, the other end of mounting rod 11 can be made to move down, so that the castor 18 in race 17 stretches out support base 1
Lower surface, in order to jack up the desk；
Step 2: the desk is pushed to certain using position by castor 18 by children；
Step 3: the first runner 7 is rotated backward, threaded rod 6 is driven to rotate backward, so that threaded rod 6 drives follow block 8 to move down,
Since the center of gravity that mounting rod 11 and castor 18 constitute structure is in mounting rod 11 about connecting shaft 10 close to one end of follow block 8, institute
With when follow block 8 no longer supports mounting rod 11, one end that mounting rod 11 is connected with castor 18 will be self-possessed in center of gravity and the desk
Under the action of move up so that the desk is supported on ground by the lower surface of support base 1, and then guarantee that the desk exists
Stabilization when use；
Then children can adjust the height of the desk, voluntarily when using the desk in order to which the height of the desk can expire
Its use demand of foot, the mode for adjusting desk height are as follows:
By 12 rotational driving gear 26 of the second runner, drives gear 26 in rotation, drive rod 30 will be dialed, thus band
Dynamic to reset shaft 28, in order to which band pawl 29 stirs transmission gear 27, in rotation, support rod 3 is supporting transmission gear 27
Height on pipe 2 will be adjusted, to achieve the purpose that adjust the desk height；
Finally, children can be rotated box frame 13, and extracting out need to the 14 (connection of collection box 14 and box frame 13 of collection box to be used
The mode that mode such as drawer is connect with desk), then the building blocks in collection box 14 are poured over to the upper surface of table frame 4, in order to
Using building blocks, after building blocks use, empty collection box 14 can be slid into box frame 13, and by rotation box frame 13, adjusted
The position of empty collection box 14, when the upper end of balancing pole 22 in the collection box 14 withstands on the lower end of convex block 16 (in building blocks from receipts
After pouring out in collection box 14, compressed spring 31 will discharge its elastic potential energy, so that it is sliding on sliding block 21, so that balancing pole 22 is upper
The upper surface of collection box 14 is stretched out at end), cover board 15 will be jacked up, then by 23 rotating plate 15 of folding shaft (when cover board 15 is not pushed up
When rising, upper surface is flushed with the upper surface of table frame 4, to be difficult to open cover board 15), and will be by cover slot 19 by table frame 4
The building blocks of upper surface are swept into empty collection box 14, and the content being not described in detail in this specification belongs to this field professional technique
