The working principle is as follows: firstly, the height-adjustable desk convenient for classifying and collecting building blocks is transported to a use position, when a child uses the desk, the desk can be automatically moved to a certain position of the use position, and the mode of moving the desk is as follows:
step 1: the threaded rod 6 is rotated through the first rotating wheel 7, so that the threaded rod 6 moves upwards, the abutting plate 8 is driven to move upwards, one end, close to the abutting plate 8, of the mounting rod 11 is lifted, the mounting rod 11, close to one end of the abutting plate 8, is lifted, the other end of the mounting rod 11 moves downwards under the action of the supporting block 9 and the connecting shaft 10, and then the caster wheel 18 in the wheel groove 17 extends out of the lower surface of the supporting base 1, so that the desk is jacked up;
step 2: the child pushes the desk to a certain position of the using position through the caster wheel 18;
and step 3: the first rotating wheel 7 rotates reversely to drive the threaded rod 6 to rotate reversely, so that the threaded rod 6 drives the abutting plate 8 to move downwards, and because the gravity center of the structure formed by the mounting rod 11 and the caster wheel 18 is positioned at one end, close to the abutting plate 8, of the mounting rod 11 relative to the connecting shaft 10, when the abutting plate 8 does not support the mounting rod 11 any more, one end, connected with the caster wheel 18, of the mounting rod 11 moves upwards under the action of the gravity center and the dead weight of the desk, so that the desk is supported on the ground through the lower surface of the supporting base 1, and the stability of the desk in use is further ensured;
then when children use this desk, can adjust the height of this desk by oneself to the height of this desk can satisfy its user demand, adjusts the mode of desk height as follows:
the driving gear 26 is rotated by the second rotating wheel 12, when the driving gear 26 rotates, the driving rod 30 is dialed, so as to drive the reset rotating shaft 28, so as to drive the pawl 29 to dial the transmission gear 27, when the transmission gear 27 rotates, the height of the supporting rod 3 on the supporting tube 2 is adjusted, and therefore the purpose of adjusting the height of the desk is achieved;
finally, the child can turn the box frame 13 and withdraw the box 14 to be used (connection of the box 14 to the box frame 13, for example, connection of the drawer to the table), dump the building blocks in the box 14 onto the upper surface of the table frame 4 to facilitate use of the building blocks, slide the empty box 14 into the box frame 13 after use of the building blocks, and adjust the position of the empty box 14 by turning the box frame 13, when the upper end of the balancing bar 22 on the box 14 is against the lower end of the projection 16 (after the building blocks are dumped from the box 14, the compression spring 31 will release its elastic potential energy to slide the slider 21 upwards so that the upper end of the balancing bar 22 protrudes from the upper surface of the box 14), lift the cover plate 15, turn the cover plate 15 by means of the folding shaft 23 (when the cover plate 15 is not lifted, its upper surface is flush with the upper surface of the table frame 4, making it difficult to open the cover plate 15), and will sweep the building blocks on the upper surface of the table frame 4 into the empty collecting box 14 through the cover slot 19, which is not described in detail in this description and is well known to the person skilled in the art.
It is to be understood that the terms "central," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for the purpose of convenience and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and are not to be considered limiting of the scope of the present invention.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
