Abstract

The utility model relates to an electrical driving drawer, which belongs to the electromechanical control electrical driving drawer group. The utility model is composed of a drawer, an outer box plate (a baffle plate for supporting and covering the drawer), and a drive and control device. The opening and the opening extents of the automatic drawer is controlled through an identity identifying disc installed on the panel of the drawer, the identity identifying disc controls a drive and control circuit, thereby controlling the motor to rotate reversely, and a transmission pair is formed through the rotating axle of the motor and the rubber wearing transmission strips, to drive the drawer. A drawer opening rotary knob is arranged on the identity identifying disc, and the opening of the drawer can be preset and modified through the drawer opening rotary knob. A touching screen formed through the outer casing of the identity identifying disc, a neon tube and a light sensitive resistor are compositely sealed into a light shading outer casing to form a photoelectric coupler, to compose a drawer driving circuit, thereby controlling the motor to rotate forward to close the drawer. A locking hook is arranged at the inner side on the rear end of a sliding track, when the drawer is completely closed, the rotary axle of the motor can be exactly driven into the U-shaped gap of the locking hook, to lock the drawer tightly.

Description

Electronic drawer

Technical field

The utility model relates to electronic drawer equipment, and by being installed in the identification dish on the drawer panel, the rotation of control motor drives the turnover of drawer, locks, unblanks.

Background technology

At present more advanced drawer equipment configuration keyboard, CPU, sensing device, Electric lock, but the opening and closing of drawer can not be carried out automatically.

The drawer that has relates to mechanical driving device, employing be screw drive, rack-and-pinion transmission, therefore be difficult to avoid in transmission, produce mechanical oscillation, and shake altogether take place with drawer, produce bigger noise.

Though can alleviate noise (conventional device is provided with reducing gear more) by the opening and closing speed that reduces drawer, but by slowing down, the opening and closing speed of drawer is slower, inapplicablely uses on the long drawer of stroke, and complex structure, the manufacturing cost height.

Specific embodiment

Below by specific embodiment, and the contrast accompanying drawing, further to the electronic drawer explanation of the utility model:

Can find out by Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5: but with forward and backward drive motors (1), be connected on the drawer backboard (2) with band spring (29) hinge (30).Rubber wear-resisting transmission bar (3) be laid in drawer sliding rail decide be fixed on jointly on the gripper shoe (5) of support drawer chute (4) upper edge.The moving chute (6) of drawer sliding rail is fixed on the drawer side (7).But the rotating shaft (8) of forward and backward drive motors (1) with the transmission basal plane (9) that rubber wear-resisting transmission bar (3) constitutes, is formed transmission, constitutes the drive unit of drawer, drive drawer into and out of.

(by the drawer side) is provided with locking bail (10) in the inboard of deciding chute (4) rear end boss (13).By the installing hole (11) on the locking bail (10), screw (12) is connected to locking bail (10) on the boss (13) versatilely, the preceding upper edge of boss (13), be provided with a locking bail locating piece (14) that laterally protrudes, to guarantee that locking bail (10) is under the effect of reset tension spring (15), with transmission basal plane (9) keeping parallelism.In below, locking bail (10) rear end one aperture (16) is arranged, with an end connect apertures (16) of reset tension spring (15), the other end is attached in the hole (17) of deciding below, chute (4) rear end.When drawer is closed fully, but the locking device of formation drawer is just in time sailed in the U-lag (18) of locking bail (10) in the rotating shaft (8) of forward and backward drive motors (1) into.

On the plate (33), be provided with a standard machinery drawer-lock (31) behind the case of locking bail (10) rear lower.Lockhole is positioned at plate (33) outside behind the case, when lock cuts out, dead bolt (32) is over against locking bail (10) rear end lower, when lock was opened, dead bolt (32) levered up locking bail (10) rear end upward, is fulcrum with screw (12), the U-lag that is positioned at locking bail (10) front end descends, discharge rotating shaft (8), drawer can be opened, and constitutes maintenance and opens drawer with assisting.

Identification dish (19), mounting bracket (20) link together by connecting bolt (21), are installed on the drawer panel (22).Identification dish operating surface (23), in the face of drawer panel (22), and with the angle of drawer panel (22), be the center of circle with connecting bolt (21), can adjustment arbitrarily between zero degree is spent with 135.

After identification dish (19) identifies correct identity, export one group of control signal, start and drive drawer drive circuit (24), it is electric that but forward and backward drive motors (1) gets, and rotating shaft (8) counter-rotating (inhour is rotated) is between rotating shaft (8), transmission basal plane (9), the U-lag (18), the interaction of power, U-lag (18) descends, and rotating shaft (8) is rolled away from, and drawer is opened automatically.The startup working time of driving drawer drive circuit (24) is subjected to time timer (25) control, and the timing of timer (25) is set by the drawer aperture knob on the identification dish (19), thereby sets the opening degree of drawer.

Touch is by the touch-screen (26) of the shell formation of identification dish (19), photoelectric coupling circuit (27) (with constituting in neon bulb and the compound encapsulation one shading shell of photo resistance), the drawer drive circuit of forming (28) that advances starts, but forward and backward drive motors (1), (clockwise rotating) just changeed in rotating shaft (8), and drawer is closed automatically.

Circuit between drawer and the outer boxboard is connected as lead by drawer sliding rail, or the flat soft line that drags connects.

Also rotating drive motors but (1) can be installed on the wallboard (5) of support drawer, with rubber wear-resisting transmission bar (3), be installed on the drawer side (7), effect is thought together.
