Detailed Description

As shown in fig. 1, the lifting device includes a slide, a rack, a lifting assembly 1 and a lifting synchronizer 2, the lifting assembly 1 is fixedly connected with the lifting synchronizer 2, two ends of the lifting assembly 1 are fixedly connected with sliders and can move up and down along the slide through the sliders, two ends of the lifting synchronizer 2 can move up and down along the rack, the slide and the rack are installed on a frame, and the frame is, for example, a cabinet body assembly 10 of an office cabinet.

Two linear sliding blocks, namely a first left sliding block 13 and a second left sliding block 14, are fixedly connected to the left end of the lifting assembly 1, and the first left sliding block 13 is positioned above the second left sliding block 14; two straight line sliders are fixedly connected to the right end of the lifting assembly 1 and are a first right slider 23 and a second right slider 24, and the first right slider 23 is located above the second right slider 24. Through four straight line sliders, the lifting assembly 1 can stably move up and down along the slide way.

The left side and the right side of the cabinet body assembly 10 are both provided with a slideway and a rack, the left side is provided with a left slideway 11 and a left rack 12, and the left slideway 11 and the left rack 12 are arranged in parallel; the first left sliding block 13 and the second left sliding block 14 are positioned in the left slideway 11 and move up and down along the left slideway 11; the right side is provided with right slide 21 and right rack 22, right slide 21 and right rack 22 set up side by side, first right slider 23 and second right slider 24 are located right slide 21, along right slide 21 up-and-down motion.
