Abstract

The utility model relates to a study desk capable of being lifted, which mainly resolves the problem that the height of a desk cavity (1) in the prior art can not be raised. The study desk is characterized in that a lead screw (7) is fixed under the desk cavity (1), a nut (14) is arranged on the lead screw (7), a fixing bolt (3) is fastened on the lead screw (7) after penetrating through the nut (14), a plane thrush bearing (13) and a radial ball bearing (12) which are fixed by supporting of steps of a bearing block (5) are arranged at external angles under the nut (14), the bearing block (5) is fixed on a desk leg (6) which is provided with a sliding chute (16), a guide pin (8) penetrating through the lead screw (7) is engaged with the sliding chute (16), and the desk leg (6) is fixed with a base (9). The study desk has the advantages of optionally adjusting the height of the desk cavity (1) thereof.

Description

A kind of liftable study table

Technical field:

The utility model relates to student's schooling apparatus field, particularly relates to a kind of liftable study table.

Background technology:

At present, in education sector, in the school or family, the used study table of student is level altitude substantially, because student learning time is long, tired easily, tall person student particularly, the height of study table is limited, reads a book, writes and must bend over, long-time sitting posture, the school grade that causes spinal curvature easily, listens to the teacher and do not concentrate, influence the student.

The utility model content:

The purpose of this utility model is the deficiency that solves the problem that the study table of prior art can not same table hall height, a kind of liftable study table that the utility model provides, and this device has the advantage that can adjust study table table hall height arbitrarily.

The purpose of this utility model is achieved by the following technical solution: the table hall of this device is fixed with leading screw by connecting plate down, nut is arranged on the leading screw, on nut, be equipped with handwheel, set bolt is through at nut mutually and is stuck on the leading screw, the place, exterior angle has the bearing block ladder to entrust fixing plain thrust bearing and radial ball bearing under the nut, and bearing block is fixed on the table leg of chute, be combined with the guide finger that is through at leading screw mutually on the chute, guide finger can be through at the leading screw lower end mutually, table leg and base fix, be equipped with stay pipe at base, rubber blanket is fixed on base end face.

The utlity model has following effect: because this device has been taked technique scheme, study table table hall can be promoted or descend, thoroughly solve the sitting posture of student problem, make sitting posture of student correct, prevented student's vertebra, cervical spondylosis, the while student listens to the teacher concentrated, improves student's school grade.

Description of drawings:

Accompanying drawing 1 is a profile of the present utility model;

Accompanying drawing 2 is table leg of the present utility model and base left view.

In the accompanying drawing: 1-table hall, 2-connecting plate, 3-set bolt, 4-handwheel, 5-bearing block, 6-table leg, 7-leading screw, 8-guide finger, 9-base, 10-stay pipe, 11-rubber blanket, 12-radial ball bearing, 13-plain thrust bearing, 14-nut, 15-handwheel, 16-chute.

The specific embodiment:

Below in conjunction with embodiment the utility model is further described:

As Fig. 1, shown in 2, this device comprises table hall 1, the table hall of this device 1 time is fixedly connected with leading screw 7 by connecting plate 2, nut 14 is arranged on the leading screw 7, on nut 14, be equipped with handwheel (4,15), set bolt 3 is through at nut 14 mutually and is stuck on the leading screw 7, and place, 14 times exterior angles of nut has bearing block 5 ladders to entrust fixing plain thrust bearing 13 and radial ball bearing 12, and bearing block 5 is fixed on the table leg 6 of chute 16, be combined with the guide finger 8 that is through at leading screw 7 mutually on the chute 16, guide finger 9 can be through at leading screw 7 lower ends mutually, is in order not allow table leg 6 and leading screw 7 produce relative rotation, thereby table hall 1 is not produced relative rotation with table leg 6, table leg 6 fixes with base 9, being equipped with stay pipe 10 at base 9, is in order to strengthen base intensity, and rubber blanket 11 is fixed on base 9 times.

During concrete operations, at first that set bolt 3 is loosening, make it no longer block leading screw 7, with hand propelled handwheel (4,15), and then drive nut 14 rotations, be combined with the guide finger 8 that is through at leading screw 7 mutually on leading screw 7 and the chute 16 and rise simultaneously or descends thereby make, and then make 1 elevated height or a reduction, after table hall 1 reaches predetermined altitude, make set bolt 3 chucking leading screws 7, make leading screw 7 and nut 14, no longer produce relative displacement no longer rotating.
