Detailed Description

In this specification, the front is the front direction of the desk, and the back is the opposite direction.

As shown in attached figures 1-5, the automatic lifting desk comprises a desk body 1, wherein a movable bin 2 is arranged at the rear part of the desk body 1, and the movable bin 2 is integrally arranged in the desk body 1 and can move up and down. When the movable bin 2 enters the desk body 1, the movable bin 2 and the upper surface of the desk body 1 are positioned in the same plane.

As shown in fig. 3, four corners of the movable bin 2 are provided with four supporting portions in the vertical direction, wherein the two supporting portions at the front are both racks 21, and the two supporting portions at the back are both sliding bars 22.

Referring to fig. 4, a slide 31 engaged with the slide 22 is provided on the inner side of the back plate 3 of the desk body 1, the slide 22 can slide in the slide 31, and a plurality of friction wheels 32 are fixed on the slide 31 to reduce friction.

As shown in fig. 5, a guide groove 41 engaged with the rack 21 is fixed to the rear side of the front portion of the desk body 1 (i.e., the front portion of the movable bin 2), the rack 21 is located in the guide groove 41, and the opening direction of the guide groove 41 and the tooth direction of the rack 21 are both forward.

The desk body 1 fixes two ends of a driving shaft 4 through bearings, the driving shaft 4 is provided with two driving wheels 42, each driving wheel 42 is meshed with one rack 21, and the driving shaft 4 fixes a second power wheel 46.

A motor 43 is fixed on one side of the desk body 1, a first power wheel 44 of the motor 43 is meshed with a speed reducing wheel 45, and the speed reducing wheel 45 is meshed with a second power wheel 46.

As shown in fig. 2, the front of the movable compartment is open, so that the book 9 can be conveniently taken out.

As shown in fig. 1 and 5, the desk body 1 is provided with a through hole 93 directly above the driving shaft 4, the driving shaft 4 is provided with a fixing hole 49 directly below the through hole 93, one end of the rope 91 is fixed on the desk body 1, a pin 92 is fixed on the other end of the rope 91, and only the end of the pin 92 can enter the fixing hole 49. The pin 92 can block the rotation of the drive shaft 4 when the end of the pin 92 can enter the fixing hole 49. In order to prevent the movable bin from falling when it is moved up, it can be blocked using a pin 92.

When the book taking device is used, as shown in the attached drawings 1-5, when a book needs to be taken, the switch of the motor 43 is started to drive the driving shaft 4 to rotate, the driving shaft 4 drives the rack 21 to ascend through the driving wheel 42, so that the movable bin 2 integrally ascends through the matching of the slide bar 22 and the slide way 31, as shown in fig. 2, the book is only conveniently taken, and the end part of the pin 92 can be inserted into the fixing hole 49 for safety.
