Description

The desk at adjustable height of table top and inclination angle

The utility model relates to a kind of desk.

Existing desk is 87203924 Chinese patent as publication number, and the adjusting of its height of table top realizes by liftable column, and positioned by fastening bolt.Its shortcoming is: 1) adjusting of height of table top is to realize by carrying or press down liftable column on artificial, because the dynamics of carrying or pressing down on artificial is wayward, so the adjusting of height of table top is accurately difficult, and also harder; 2) phenomenon of the sliding tooth of bolt in use can appear in desk, causes to locate height instability unreliable, desk, and perhaps rocking appears in desktop.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, the desk at a kind of adjustable height of table top and inclination angle is provided, so that the adjusting of height of table top is accurate, light, reliable, and make it have adjustable desktop inclination angle, can keep off the whereabouts of desktop article, and can clamp the characteristics such as paper on the desktop.

The desk at adjustable height of table top of the utility model and inclination angle, it contains desktop, the table pin, the table pin includes hollow inner prop and column jacket, the inner prop kink is in column jacket, and have lowering or hoisting gear between inner prop and the column jacket, its feature is: its lowering or hoisting gear includes gear and the tooth bar that is equipped with in inner prop, its middle rack is fixed on the internal face of inner prop, gear is installed in axle and goes up and mesh with tooth bar, axle passes from inner prop and column jacket and is overhanging, on its overhanging end worm gear is housed, the worm screw of the same band rocking handle of this worm gear is meshed, and have on the inner wall can for the axle on, the slotted hole of lower slider.

The desk at adjustable height of table top of the utility model and inclination angle, the device that has adjustable desktop inclination angle between its desktop and the table pin, this device includes the following flange that is fixed in the desktop bottom, the last flange that is fixed in a pin top, and bearing pin, be positioned at the arc-shaped through-hole on the following flange, bearing pin is fixed on the flange and kink is connected down in the arc-shaped through-hole of flange, and the bearing pin end has the nut of fastening usefulness.

The desk at adjustable height of table top of the utility model and inclination angle, have clip board equipment on its desktop, this clip board equipment includes clip board, connecting rod, and connecting rod can be flexibly connected lower bearing pin on the table and can make clip board be fixed on pin on the connecting rod, compress the spring of usefulness.

When regulating the utility model table height, rotatable rocking handle rotates worm screw, at this moment worm screw drives the worm gear rotation, by axle gear is rotated again, thereby make the rack drives inner prop that is engaged with in column jacket, do corresponding upper and lower slip, realize the rising or the decline of desktop: when desktop arrives setting height, i.e. stop rotation crank, at this moment worm gear, worm screw, gear, tooth bar are all left alone without help stays on this position, and is locked on this height by the self-locking action of worm and gear.

The utility model has the advantages that: 1) the desktop adjustment process is to realize by the gear motion of worm and gear and rack-and-pinion, so more accurate, light and reliable, stable to the locking of height to the adjusting of height; 2) the utility model desk height of adjustable desktop not only, but also adjustable desktop inclination angle, and also have the clip board equipment that can prevent the baffle plate that article fall and can clamp the desktop paper on the desktop, so its easy to use, reliable, make that it becomes reading, writes, designs, drawing, music etc. learn the employed desirable desk of colony.

To and contrast accompanying drawing by embodiment below the desk at adjustable height of table top of the utility model and inclination angle will be done narration further.Accompanying drawing thes contents are as follows:

Fig. 1 is the stereogram of the desk at adjustable height of table top of the utility model and inclination angle;

Fig. 2, Fig. 3 and Fig. 4 are respectively rearview, front view and the vertical views of the desk at adjustable height of table top of the utility model and inclination angle;

Fig. 5 is that A among Fig. 3 is to view.

From Fig. 1～Fig. 4, can see the structure of the desk at adjustable height of table top of the utility model and inclination angle, it contains desktop 1, table pin 2, the table pin includes hollow inner prop 21 and hollow column jacket 22, and the inner prop kink and has lowering or hoisting gear between inner prop and the column jacket in column jacket.This lowering or hoisting gear includes gear 32 and tooth bar 31 is housed in inner prop, its middle rack is fixed on the internal face of inner prop, gear is installed on the axle 33 and with tooth bar 31 engagements, axle 33 passes from inner prop and column jacket and overhanging, and the worm gear 34 that is meshed with worm screw 35 with rocking handle 37 is housed on this overhanging end; Having on the inner wall can be for the slotted hole 23 of axle 33 upper and lower slips within it.Rotation crank 37 can make worm screw drive worm gear 34 motions, and by axle 33 driven gears, tooth bar, the inner prop affixed with tooth bar promptly slides up and down in column jacket accordingly again; When desktop arrives setting height, the rotation stop of rocking handle, worm gear, worm screw, gear, tooth bar stop immediately are motionless, and desktop is locked on this height and position.

The desk at adjustable height of table top of the utility model and inclination angle, the device that also can have adjustable desktop inclination angle between its desktop and the table pin, this device can be seen from Fig. 1, Fig. 2, Fig. 3 and Fig. 5, it includes the following flange 11 that is fixed in the desktop bottom, the last flange 24 that is fixed in a pin top, and be positioned at the arc-shaped through-hole 41 on the following flange and be fixed in flange also kink at the bearing pin 42 of the threaded end of the arc-shaped through-hole of flange down, the nut 4 of fastening usefulness.Clamp nut in the present embodiment is a wing nut.With convenient manual turn.When needs are regulated the inclination angle of desktop, can unscrew nut 4 and rotary desktop, at this moment desktop is along with the arcuate socket 41 on the flange down slides and yaw tilt on bearing pin 42, gets final product fastening nut when waiting to go to the angle of setting, and desktop just remains on this inclination angle.

The desk at adjustable height of table top of the utility model and inclination angle, can have clip board equipment on its desktop, this clip board equipment can be seen from Fig. 1～Fig. 4, it comprises a rectangular clip board 51, connecting rod 52, and connecting rod can be connected lower bearing pin 53 on the table and can make clip board be fixed on pin 54 on the connecting rod, compress the spring 7 of usefulness.Spur connecting rod 53 to the left or to the right, clip board can be up or down; In the time of downwards, the horizontal top surface on the clip board can be pushed down page, and is compressed by spring 7, has kept the clamped condition of paper; Oppositely at this moment pulling connecting rod 52 has overcome spring force and has taken out page.

From Fig. 1, Fig. 3 and Fig. 4, can see the baffle plate 62 in the utility model desk, have through hole 63 on this baffle plate, be fastened on screw 61 kinks in the sidewall of desktop 1 in through hole 63.Unclamp nut 4, baffle plate can be done upper and lower inclination and move in the altitude range of through hole, blocks height thereby regulated baffle plate retaining on the table; Fastening nut 4 can be kept this retaining and block height.
