Detailed description of the invention
In order to more clearly state technical characteristic of the present utility model, illustrate in greater detail below in conjunction with accompanying drawing.
As shown in Figure 1-2, a kind of height adjustable desk, is made up of desktop 1, fixing table leg 21, movable table leg 22, table pin 3, link 4 and height-regulating device; Described desktop version and movable table leg 22 are welded to connect, and can realize sliding up and down in the guide rail that movable table leg 22 is stuck in fixing table leg 21, and fixing table leg 21 is welded on a pin 3, and two table pin 3 are welded together by link 4.
As Figure 1-5, height-regulating device of the present utility model by heightening pinion 5, heighten main shaft 6, heighten tooth bar 7, set lever 8, locking ratchet 9, locking gear 10, fixed axis 11, transmit gear 12, heighten master gear 13, bearing 14, heighten countershaft 15, heighten handle 16, locking nut 17, protective jacket 18, protection block set 19 and protection end cap 20 form; Heighten and main shaft 6 is provided with two and heightens 14, one, pinion 5, two bearings and heighten master gear 13, heighten main shaft 6 and be arranged on fixing table leg 21 through movable table leg 22, fixing table leg 21; Be fixed on movable table leg 22 with the tooth bar 7 of heightening heightening pinion 5 engaged transmission, being arranged on the transmission gear 12 heightening master gear 13 engaged transmission heightens on countershaft 15, meanwhile, heighten countershaft 15 also arranges locking gear 10, lock with locking nut 17 heighten handle 16; The locking ratchet 9 forming intermittently-driving with locking gear 10 is arranged on fixed axis 11, and fixed axis 11 is arranged on fixing table leg 21; Locking ratchet 9 is provided with set lever 8; Protection end cap 20 is arranged on the left of desk, is provided with the protection block set 19 being fixed on fixing table leg 21 on the right side of desk, and protective jacket 18 is arranged in protection block set 19.
As Fig. 1-5, composition graphs 6, Fig. 7, operation principle of the present utility model is as follows: when needs lifting tabletops plate 1, effect set lever 8, push locking ratchet 9 aside, locking gear 10 can be rotated, namely unclamp and heighten countershaft 15, then manually handle 16 is heightened to rotate clockwise, now heighten countershaft 15 to rotate, transmission gear 12 is driven to rotate clockwise, the master gear 13 of heightening engaged with transmission gear 12 rotates counterclockwise, so heighten main shaft 6, heighten pinion 5 to rotate with identical direction, with heighten that pinion 5 engages heighten tooth bar 7 upward sliding, because movable table leg 22 is be fixedly connected with heightening tooth bar 7, movable table leg 22 is along the guide rail upward sliding of fixing table leg 21, realize the rising of desktop 1.After heightening suitable height, pull set lever 8, locking ratchet 9 blocks locking gear 10, and at this moment heightening countershaft 15 cannot rotate, and realizes stablizing heightening securely.In like manner, when needing the height reducing desktop 1, effect set lever 8, pushes locking ratchet 9 aside, heightens handle 16 to rotate counterclockwise, and after dropping to suitable height, after pulling set lever 8, realizes the adjustment reducing height.
