Detailed description of the invention
As shown in Figures 1 to 7, the present invention provides a kind of child learning desk, including table leg 1, it is fixed on a stay tube 2 of table leg 1 upper end, the connecting tube 3 being fixed on a stay tube 2 and the table 4 being rotatably connected in connecting tube 3, connecting tube 3 is provided with at least one hinge 31, and the edge of table 4 is rotatably connected in connecting tube 3 by hinge 31.
nullRotation locking in order to simplify table 4 conciliates latching operation,Described stay tube 2 is provided with locking wrench 5,Described locking wrench 5 includes the articulated elements 51 with rotating shaft 511、It is rotatably connected on the some bump contacted chips 52 in rotating shaft 511 and can lock or unclamp the controlling organization connecting sheet 52,Described controlling organization includes the sleeve 53 being fixed on a stay tube 2、It is located at the drive rod 54 in sleeve 53、It is connected to the baffle plate 55 of drive rod 54 one end、It is located at the first spring 56 between baffle plate 55 and sleeve 53 bottom surface and is located in sleeve 53 and against the drive block 57 of baffle plate 55,The other end of described drive rod 54 stretches out sleeve 53 and is connected sheet and 52 is rotationally connected,Drive rod 54 is arranged with some pieces of the first friction plates 58,Every bump contacted chip 52 is located between two piece of first friction plate 58,Described drive rod 54 is through connecting the threaded locking nut 59 of sheet 52,Described first spring 56 applies resilience force to baffle plate 55 makes connection sheet 52 and the first friction plate 58 be locked between locking nut 59 and a stay tube 2,Described sleeve 53 is provided through the first bearing pin 531 of drive block 57,Described drive block 57 compresses the first spring 56 around the first bearing pin 531 rotation driving baffle plate 55 and connection sheet 52 and the first friction plate 58 is unclamped.
The end of drive rod 54 has external screw thread, rotated on the external screw thread of drive rod 54 by locking nut 59, drive rod 54 is driven to move to connecting sheet 52 direction, baffle plate 55 compresses the first spring 56, baffle plate 55 is applied resilience force by the first spring 56, make locking nut 59 be pressed on the tube wall of a stay tube 2 by connection sheet 52 and the first friction plate 58, connect sheet 52 and be subject to the rubbing action of the first friction plate 58 and cannot rotate around drive rod 54, thus by table 54 locking;
When needs rotate table 4, have only to make drive block 57 rotate around the first bearing pin 531, drive block 57 can extend protuberance be easy to grip, operation drive block 57 rotation urging is convenient, and drive block 57 just can drive baffle plate 55 to move to the first spring 56 against one end of baffle plate 55, and the first spring 56 is compressed, now, connecting sheet 52 and the first friction plate 58 unclamps, connect sheet 52 and just can rotate around drive rod 54, table 4 is with regard to automatic unlocking;Table 4 rotates after being adjusted in place, unclamp drive block 57, first spring 56 automatically resets, resilience force is applied on baffle plate 55 by the first spring 56 again, together with connection sheet 52 is forced into again with the first friction plate 58, table 4 is locked out rotation again, so, greatly simplify the locking rotating table 4 and conciliate latching operation process, teenager is more convenient to use.
In order to make the locking nut 59 compression better effects if to connecting sheet 52, between locking nut 59 and connection sheet 52, it is provided with pad 291.
Described drive block 57 is connected to handle 571, drive block 57 is provided with the first groove 572, described handle 571 inserts the first groove 572 and coordinates, described sleeve 53 is provided through the second bearing pin 532 of drive block 57 and handle 571, the nozzle of sleeve 53 extends to form arc-like sheet to handle 571, arc-like sheet is provided with the pilot hole for the second bearing pin 532 traverse, drive block 57 is remained to rotate around the first bearing pin 531 by under the effect of the second bearing pin 532, second bearing pin 532 is perpendicular to the length direction of a stay tube 2 and arranges, first bearing pin 531 and the second bearing pin 532 are vertically arranged, drive block 57 is provided with through the breach 573 of the first groove 572 along the length direction propping up stay tube 2.Handle 571 rotates around the second bearing pin 532 just can be embedded into breach 573, so, handle 571 just can along the folded lengthwise storage of stay tube 2, it is to avoid handle 571 protrudes, and affects use, even causes teenager to bump to handle 571 and injured.
The bottom surface of described first groove 572 is provided with the first spherical groove 574, the bottom surface of described first spherical groove 574 is provided with the second groove 575, described second groove 575 is provided with the second spring 576, the end of the second spring 576 is placed with ball 577, handle 571 stretches into the end of the first groove 572 and has sphere 5721, sphere 5721 is provided with the second spherical groove 5722, sphere 5721 is rotatably assorted the first spherical groove 574, second spherical groove 575 is rotatably assorted ball 577, and sphere 5721 or the second spherical groove 5722 compress the second spring 576 by ball 577.When ball 577 is arranged in the second spherical groove 5722, owing to the second spring 576 applies resilience force to ball 577, ball 577 will apply pressure to the second spherical groove 5722, handle 571 will keep locking in certain acceptance range, operator is when operating handle 571 and driving described drive block 57, and handle 571 will not arbitrarily rotate skidding;And when handle 571 needs to be folded into breach 573, handle 571 is exerted a force, make the second spherical groove 5722 depart from ball 577, by sphere 5721 against ball 577, sphere 5721 is only small with the force of rolling friction of ball 577, folds up very comfortable, it is simple to the teenager that strength is little uses.
In order to improve the rotation lock effect of table 4 further, described rotating shaft 511 is fixedly connected with the second friction plate 512, every bump contacted chip 52 is located between two piece of second friction plate 512, when connecting sheet 52 and being pressed between locking nut 59 and a stay tube 2, owing to the gap of adjacent two bump contacted chips 52 diminishes, connect sheet 52 to be also close together mutually with the second adjacent friction plate 512, connect sheet 52 and be subject to the frictional force of the second friction plate 512, it is prevented that table 4 rotates around articulated elements 51.
In order to prevent operation locking wrench 5 unlock table 4 rotate time, table 4 rotates down suddenly because of self gravitation effect, prop up stay tube 2 and be provided with the second connecting tube 3a, it is provided with air spring 6 between table 4 and the second connecting tube 3a, the lower surface of described table 4 is provided with the first hinge 61, described second connecting tube 3a is provided with the second hinge 62, and the upper end of described air spring 6 and the first hinge 61 are rotationally connected, and the lower end of air spring 6 and the second hinge 62 are rotationally connected.
Described second hinge 62 is located on the lower surface of connecting tube 3, when air spring 6 so can be made to rotate with table 4, will not being interfered by the second connecting tube 3a, so increasing the maximum angle that air spring 6 rotates with table 4, also increasing the maximum angle that table 4 rotates accordingly.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can be variously modified according to the present invention and deform, and without departing from the spirit of the present invention, all should belong to scope defined in claims of the present invention.
