Abstract

Disclosed is an electric collapsible table which comprises a movable table board and a collapsing device composed of an electromotor, a drive chain and a dump rail. The utility model has the advantages of convenient usage, reliable performance and small occupying area, and can be enlarged when in use, thus the utility model is an ideal household article.

Description

Electronic convergent-divergent table

Affiliated technical field

The utility model relates to a kind of household supplies---desk, particularly can dwindle the electronic convergent-divergent table of amplification.

Background technology

The desk every household that present crowd knows has, owing to vary in size, its shared space is also different, and big table floor space is big, and the teapoy usable floor area is little, and the people is not enough for a long time.

Summary of the invention

Take up an area of when putting in order to solve this desk little, the difficult problem that the time spent area is big, the utility model provides the electronic convergent-divergent table that a kind of time spent can be big, can be little when putting.

The utility model solves the scheme that its technical problem takes: be divided into two desktops in the centre of teapoy, these two can be movable desktop beneath also have one can lifting desktop, when two top desktops separate automatically, that beneath piece desktop just rises automatically, like this, the desk of positive square has originally just formed the desk of a rectangle, has enlarged usable floor area.

The beneficial effects of the utility model are, can place the bigger desk of usable floor area in less place, decontrol when needed, and conserve space, and also unique generous.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the schematic diagram of the electronic convergent-divergent table of the utility model.

Fig. 2 is this schematic diagram of emitting to both sides.

Fig. 3 is the schematic diagram after this middle desktop all rises.

Fig. 4 is the transmission device principle schematic of middle desktop automatic lifting.

The principle schematic of Fig. 5 electric transmission machanism that to be desktop separate automatically to both sides.

Among the figure 1, be leg of a table and frame, 2, the desktop track, 3, left desktop, 4, the last lifting push rod of middle desktop, 5, middle desktop, 6, the desktop rail bracket, 7, right desktop, 8, lifting push rod, 9, lifting motor, 10, the lifting push rod, 11, lifting push rod, 12 lifting push rods, 13, drive chain, 14, movable wheel, 15, drive chain, 16, left desktop connecting rod, 17, mobile motor, 18, right desktop connecting rod, 19, movable wheel.

The specific embodiment

Connect power supply, open the switch of mobile motor (17), at this moment left desktop (3) and right desktop (7) move to both sides respectively, mobile motor during to certain position (17) stops automatically, lifting motor (9) is started working simultaneously, rotate simultaneously through driving chain (13) drive screw mandrel type elevating lever (8,10,11,12), middle desktop (5) is upwards promoted, until with till the desktop of left and right desktop (3,7) is equal, lifting motor (9) just quits work automatically, the process knot speed that desktop is decontroled.

When receiving desktop, open the switch of lifting motor (9), it is auto-reverse, drives screw mandrel type elevating lever (8,10,11,12) opposite spin through driving chain (13), and middle desktop (5) descends automatically, automatically stop during to certain position, mobile motor (17) also begins work in the other direction simultaneously, left and right sides desktop (3,7) is received simultaneously inwards, till closing up, motor just quits work, whole process knot speed.

Claims

1. can receive the electronic convergent-divergent table that can put for one kind, it has the motor that drives desktop rising in left and right sides desktop mobile motor and the drive, it is characterized in that: the mobile motor (17) that drive left and right sides desktop moves is through driving chain (15) work.

2. electronic convergent-divergent table according to claim 1 is characterized in that: the lifting motor (9) that desktop in the drive (5) rises carries out lifting through driving chain (13) drive lifting push rod (8) (10) (11) (12).
