Abstract

Disclosed is a study desk with adjustable height and inclination angle, belonging to desk field. The study desk is suitable for students in all ages and is suitable to be used as an office desk, a microcomputer desk and a drawing desk. The utility model mainly adopts the technical scheme that a fixing plate is fixed at the underside of a desk top; two axle beds are fixed on the fixing plate through bolts; a screw rod is installed in the axle beds and is axially fixed in the axle beds through a retainer block and a retainer ring; a nut is installed on the screw rod; a push rod is installed on the nut through a pin roll; the other end of the push rod is installed through a shaft in the axle beds fixed on the underside of the desk top; the desk top is connected with a vertical plate through a gemel; and a detachable crank is installed on the head of the screw. The study desk has the advantages that the inclination angle of the desk top can be adjusted freely without affecting the other people; the study desk is simple in structure; and provided with bearings, the lifting screw and the rotating shaft are flexible to rotate and convenient to lift and descend.

Description

Can heighten study table low, the angle of inclination

One: technical field:

The utility model belongs to field of tables.

Two: background technology:

Present desk kind is a lot, have student classroom with the table, have desk, again have a meal with the table or the like, these desks still are special purpose, multi-functional desk is also arranged, for example: the day for announcing: on October 29th, 2008, the patent No.: ZL200720175077.8, title: multi-functional automatic lifting study table.This desk major technique is: each fixes square tube on below the centre position, two of desk framework, square tube is enclosed within respectively on the following square tube that is fixed on the cross bar that connects ground on this, each fixes an axle bed in the pipe up, one rhizoid Bars axle respectively is installed in axle bed, each fixing bevel gear of the upper end of silk Bars axle, the screw thread of silk Bars axle partly is contained on the nut that is fixed on down in the square tube, bevel gear on the silk Bars axle and the bevel gear engagement that is contained in turning cylinder two, turning cylinder is fixed in the square tube with axle bed; Respectively adorn a box body at two, the back side of desk, elongated turning cylinder is housed in the box body links up two box bodys, on the turning cylinder in two box bodys, respectively adorn a bevel gear, the bevel gear engagement on the screw rod on bevel gear and two axle beds that are contained in the box body, screw rod is contained in the microscler square nut.This desk major defect is: adorn the mechanism of the adjustment desktop angle of a nested structure complexity at the back side of desk, if double table, a people will transfer the angle of desktop, when a people does not transfer the angle of desktop, has coordinated with regard to bad.In the mechanism of lifting desk height, do not have bearing on the axle in addition, rotate effort.Owing to above shortcoming is arranged, so will improve to it.

Three: summary of the invention:

The purpose of this utility model is exactly to design a kind of angle that can adjust desktop separately, does not influence during adjustment that other people can heightening is low, the study table at angle of inclination.

The technical scheme that the utility model technical solution problem adopts: below desktop, fix a fixed head, be screwed two axle beds on the fixed head, adorn a rhizoid thick stick in the axle bed, leading screw carries out axial restraint with block and baffle ring in axle bed, nut is housed on the leading screw, adorns a push rod with bearing pin on the nut, the push rod other end is contained in the axle bed that is fixed on below the desktop with one, be connected with hinge between desktop and the riser, adorn a dismountable crank on the leading screw head; Bearing is equipped with in turning cylinder and square tube junction, between the bevel gear and the fixed block in the square tube on the lead screw shaft, pressure bearing is housed all between the boss on fixed block and the lead screw shaft.

The beneficial effects of the utility model are: desktop is the angle of inclination arbitrarily, and does not influence other people, and simple in structure; Owing on elevating screw and the turning cylinder bearing is housed, to rotate flexibly, lifting is convenient.

Four: description of drawings:

Fig. 1 is that the B-B of Fig. 2 is to cross-sectional schematic.

Fig. 2 be the A-A of Fig. 1 to cross-sectional schematic, and be front elevational schematic of the present utility model.

Five: the specific embodiment:

Describe details of the present utility model and working condition in detail in conjunction with Fig. 1, Fig. 2.Desk all has desktop 9, and the desk of study usefulness has drawer 23, and desk also must have leg 24.Below desktop 9, fix a fixed head 20, fix two axle beds 2 with screw 11 on the fixed head, adorn a rhizoid thick stick 1 in the axle bed, leading screw carries out axial restraint with block 4 and baffle ring 3 in axle bed, nut 5 is housed on the leading screw, adorns a push rod 6 with bearing pin 22 on the nut, the push rod other end is contained in 7 li of the axle beds that are fixed on below the desktop with one 8, be connected with hinge between desktop 9 and the riser 21, adorn a dismountable crank 10 on 1 of the leading screw.As long as leading screw 1 rotates, nut 5 will move on leading screw, because nut moves, the push rod 6 on the nut just can or put down desktop 9 jack-up, because be with hinged between desktop and the riser 21, so energy jack-up or put down.Push rod 6 can be movable across fixed head 20, and desktop can set level, and is owing to have a long slot bore 25 on fixed head 20.On push rod, done one section flat segments 21.Turning cylinder 26 is equipped with bearing 12 with square tube 14 junctions, between the fixed block 18 that bevel gear 15 on the lead screw shaft 16 and square tube are 14 li, between the boss 17 on fixed block 18 and the lead screw shaft 16 pressure bearing 13 is housed all.Because turning cylinder and lead screw shaft all are equipped with bearing, so rotate flexibly, lifting is convenient.
