Be designed in this way, no matter desk be placed in where, can from more conveniently position and direction complete to desktop Height is continuously adjusted with flip angle.One of the technical features not disclosed in this embodiment and specific embodiment one to six It is identical.

Working principle

When being adjusted, to being highly adjusted, hand height of table top release handle 4 is inserted into any one lift in height hole In 7-1, hand height of table top release handle 4 is rotated, is nibbled by second connecting rod 12-1 or third connecting rod 12-10 rotation driven gear pair Transmission is closed, and then the second screw rod 12-8 and third screw rod 12-9 and support frame 3 is driven to relatively rotate, realizes the tune to height of table top Section；While height adjustment, the pinion gear 13-1 being connected with second connecting rod 12-1 is also rotated simultaneously, is engaged and is passed by between cog It is dynamic, drive connecting plate 13-4 to move adjusting indicator 13-5 on bottom plate 13-6 by gear wheel 13-2 and rack gear 13-3, when When adjusting suitable height, adjusting indicator 13-5 is moved to by the groove on bottom plate 13-6 using memory sliding block 13-7 It sets, record user's name and uses height number；When desktop flip angle is adjusted, hand desktop is overturn and is adjusted Section handle 5 is inserted into any one desktop tumble port 7-2, rotates hand desktop overturning release handle 5, overturns driving dress by desktop The first connecting rod 11-1 in 11 is set to drive gear pair to rotate and then drive the rotation of the first screw rod 14 or directly drive the first screw rod 14 Rotation drives separable thread slider 10 to move on the first screw rod 14, passes through the desktop being connected with separable thread slider 10 The overturning that strut 8 pushes desktop 1 angled.

When the height and flip angle regulated at present is not suitable for, hand height of table top release handle 4 need to be only reversely rotated Overturn release handle 5 with hand desktop, so that it may realize the reduction of height of table top and flip angle, complete continuously to desk for children into The adjusting of row height and angle.

During the decline of desktop flip angle, occur foreign matter (such as children's finger) between desktop 1 and desk dock 7 When, if continuing to rotate hand desktop overturning release handle 5, moving resistance increases, and makes the threaded block 10- in separable thread slider 10 2 separation, at this moment the first screw rod 14 dallies, and desktop flip angle will not continue to reduce, and reduces the further injury to foreign matter；When It when removing foreign matter, need to only rotate backward, threaded block 10-2 is closed under spring 10-3 effect, is continued to complete to desktop flip angle Decline adjust.
