Abstract

The utility model discloses a liftable desk. The liftable desk comprises a desktop and desk legs, wherein, four connection blocks are arranged at the four desk corners on the lower surface of the desktop and form an isosceles trapezoid; each connection block is hinged with a desk leg; two desk legs on the same waist of the isosceles trapezoid are mutually crossed; a circular through hole and a strip-shaped groove which is formed along the length direction of each desk leg are formed on the joint surface of each of the mutually crossed desk legs; the through hole is formed between the strip-shaped groove and the ground-contact part of the desk leg; the two crossed desk legs are connected together through a limit pin, so as to rotate relatively; a plurality of projections uniformly distributed along the length direction of the desk leg are formed between the strip-shaped groove and the hinge hole on the desk leg, and on the desk leg on the outer side surface perpendicular to the side on which the strip-shaped groove is formed; and the circular through holes on the desk legs on the same plane are connected with the two ends of a straight rod which is bent four times by 90 degrees, so as to form the supporting structure of the whole desk. The desk has the advantages that the height of the desk can be adjusted according to the requirements, the stationarity is higher, the structure is simple, and the operation is easy.

Description

Lifting table

Technical field

The utility model relates to a kind of desk, particularly a kind of lifting table.

Background technology

At present, because growth in the living standard, people are doing very big effort aspect the architecture advances of desk, the improvement of lifting table structure has also obtained certain effect, as Chinese utility model patent number is ZL200720079128.7, referring to Fig. 4, is to connect into movable table leg by the table legs that butterfly shape clamping screw will be divided into two joints, butterfly shape clamping screw passes the transverse link that a center has groove, carries out adjusting to table height by regulating butterfly shape clamping screw.But this liftable desk needs people that there is good assurance the position of adjusting butterfly shape clamping screw.When the butterfly shape clamping screw position on both sides was not symmetrical with respect to the desktop center, desk was with run-off the straight, and it is convenient inadequately to use.

The utility model content

The purpose of this utility model just is to provide the degree of balance higher, simple in structure lifting table.

To achieve these goals, the technical solution adopted in the utility model is such: the utility model comprises desktop and table leg, place, four table angles of the lower surface of desktop is provided with a contiguous block respectively, described contiguous block is isosceles trapezoidal structure and distributes, each contiguous block all adopts articulated manner to be connected with a table leg, two table legs that are positioned on the same waist of isosceles trapezoid intersect mutually, and the table leg tread surface is a semi circular surface, on intersecting the face of fitting mutually, table leg has a manhole and a bar-shaped trough along the table leg length direction, through hole contacts to earth between the part at bar-shaped trough and table leg, article two, the table leg that intersects links together by a position-limitting pin that passes bar-shaped trough, and can relatively rotate; Simultaneously between the hinge hole on bar-shaped trough and the table leg, be provided with several along the equally distributed projection of table leg length direction, described projection is positioned on the lateral surface vertical with bar-shaped trough place face on the table leg, the support bar two ends that are bent to form by the same directions of a straight-bar four times 90 degree be positioned at conplane two table legs on manhole be connected the supporting construction of formation entire table.For the distribution that adapts to contiguous block can table leg being played a supporting role, then described two support bars are a long weak point; The length of strut of drawing money on credit equals the long base of isosceles trapezoid that contiguous block is formed, and the length of short support bar equals described trapezoidal short base.

Compared with prior art, advantage of the present utility model is: the stationarity of this lifting table is higher, and is simple in structure easy to operate.

The specific embodiment

Referring to Fig. 1,4 contiguous blocks 2 and the table leg 4 that are provided with on four angles of desktop 1 by lower surface flexibly connect, the contiguous block 2 that is provided with is the isosceles trapezoid shape and distributes, two table legs 4 that are positioned on the same waist of isosceles trapezoid intersect mutually, on intersecting the face of fitting mutually, table leg 4 has a manhole 9 and a bar-shaped trough 6 along table leg 4 length directions, through hole 9 contacts to earth between the part two at bar-shaped trough 6 and table leg 4 and intersects table leg 4 and link together by a position-limitting pin 7 that passes bar-shaped trough 6, and can relatively rotate; Simultaneously between the hinge hole on bar-shaped trough 6 and the table leg 4, be provided with three along the equally distributed projection 5 of table leg 4 length directions, described projection 5 is positioned on the lateral surface vertical with bar-shaped trough 5 place faces on the table leg 4, the support bar 8 that is bent to form by the same directions of a straight-bar four times 90 degree passes described through hole 9 and is positioned at conplane two table legs 4 and is connected the supporting construction of formation entire table.Table leg 4 tread surfaces are semi circular surface, and table leg 4 and ground contacts when helping desk and being in differing heights.For the distribution that adapts to contiguous block 2 can table leg 4 being played a supporting role, two support bars 8 are designed to a long weak point; The length of strut 8 of drawing money on credit equals the long base of isosceles trapezoid that contiguous block 2 is formed, and the length of short support bar 8 equals described trapezoidal short base.

Referring to Fig. 2, set projection 5 is three, and when support bar 8 is positioned at second projection 5 times, because the position-limiting action of projection 5, desk will be in certain height stably.

Referring to Fig. 3, when the support bar 8 at table leg two ends is positioned at bottom projection 5 times, desk will raise relatively.

Claims

1. lifting table, comprise desktop and table leg, the lower surface of desktop is provided with a contiguous block respectively near place, four table angles, described contiguous block is isosceles trapezoidal structure and distributes, each contiguous block all adopts articulated manner to be connected with a table leg, two table legs that are positioned on the same waist of isosceles trapezoid intersect mutually, and the table leg tread surface is a semi circular surface, it is characterized in that: on table leg intersects the face of fitting mutually, have a manhole and a bar-shaped trough along the table leg length direction, through hole contacts to earth between the part at bar-shaped trough and table leg, article two, the table leg that intersects links together by a position-limitting pin that passes bar-shaped trough, and can relatively rotate; Simultaneously between the hinge hole on bar-shaped trough and the table leg, be provided with several along the equally distributed projection of table leg length direction, described projection is positioned on the lateral surface vertical with bar-shaped trough place face on the table leg, the support bar two ends that are bent to form by the same directions of a straight-bar four times 90 degree be positioned at conplane two table legs on manhole be connected the supporting construction of formation entire table.
