driving gear

4a, 4b and a pair of driven

tooth bar

5a, 5b, wherein, a pair of

driving gear

4a, 4b rotatably be located at respectively shelf 1 left and right end downside and be connected to drive first support bar 2 with the two ends of first support bar 2 and pivot, alternatively, a pair of

driving gear

4a and 4b are sector gear.Alternatively, the central angle of

driving gear

4a and 4b is the 80-150 degree.A pair of driven

tooth bar

5a, 5b cooperate correspondingly with the rotation with

driving gear

4a, 4b with a pair of

driving gear

4a, 4b respectively and are converted into moving forward and backward of driven

tooth bar

5a, 5b, and a pair of driven

tooth bar

5a, 5b are connected to drive second support bar 3 with the two ends of second support bar 3 respectively and move forward and backward.

For example as Fig. 3 and shown in Figure 7, driving gear 4a rotatably is located at the downside of the left end of shelf 1, driving gear 4b rotatably is located at the downside of the right-hand member of shelf 1, and driving gear 4a is connected with the left connection part 2a of first support bar 2, and driving gear 4b is connected to drive first support bar 2 with the right connection part 2b of first support bar 2 and pivots.Simultaneously driven tooth bar 5a cooperates with the rotation with driving gear 4a with driving gear 4a and is converted into moving forward and backward of driven tooth bar 5a, driven tooth bar 5b cooperates with the rotation with driving gear 4b with driving gear 4b and is converted into moving forward and backward of driven tooth bar 5b, and driven tooth bar 5a is connected with the left connection part 3a of second support bar 3, and driven tooth bar 5b is connected to drive second support bar 3 with the right connection part 3b of second support bar 3 and moves forward and backward.

At this moment, in the time of need depositing bottle, rotate to the upright position from horizontal level with hand propelled first support bar 2, a pair of driving gear 4a, the 4b that be connected with first support bar 2 this moment rotates, and by the cooperation of driving

gear

4a, 4b and driven

tooth bar

5a, 5b, driven

tooth bar

5a, 5b move forward and backward, thereby drive second support bar 3 from after move forward, control folding and expansion process of rack assembly 100 by the engagement of rack-and-pinion, simple to operate and stable, easy to maintenance.

As Fig. 2-shown in Figure 7, according to one embodiment of present invention, rack assembly 100 further comprises a pair of

hinge seat

6a, 6b and a pair of pivotal axis 7a, 7b, wherein, a pair of

hinge seat

6a, 6b is separately fixed at the left side of shelf 1, on the lower surface of right-hand member, and a pair of

driving gear

4a, 4b is installed in a pair of hinge seat 6a respectively, on the 6b, a pair of pivotal axis 7a, 7b is located at a pair of hinge seat 6a respectively correspondingly, last and the driving gear 4a of 6b, 4b can be with respect to corresponding pivotal axis 7a, 7b pivots, by

hinge seat

6a, 6b and pivotal axis 7a, 7b is driving gear 4a, thereby 4b is connected to the downside of shelf 1 and drives first support bar 2 and pivot, and makes rack assembly 100 easy to assembly and Stability Analysis of Structures.

Particularly, as Fig. 2-shown in Figure 7, hinge seat 6a is fixed on the lower surface of left end of shelf 1, and driving gear 4a is installed on the hinge seat 6a, and pivotal axis 7a is located at that hinge seat 6a goes up and driving gear 4a can pivot with respect to pivotal axis 7a.Hinge seat 6b is fixed on the lower surface of right-hand member of shelf 1, and driving gear 4b is installed on the hinge seat 6b, and pivotal axis 7b is located at that hinge seat 6b goes up and driving gear 4b can pivot with respect to pivotal axis 7b.
