Description

Technical Field

[0001] The utility model relates to the technical field of drawer storage cabinets, in particular to a drawer type storage cabinet. Background Art

[0002] Generally, drawer-type lockers are provided with multiple drawers that can slide individually on the cabinet body. However, there are now drawer-type lockers with multiple drawers that can be linked together on the market, in which two drawers are connected to each other by a connecting rod, and a guide piece is provided in the cabinet layer. By pulling the main drawer, the other sub-drawer can be synchronously linked with the main drawer through the connecting rod, and a pulley group that cooperates with the guide piece for limited sliding is provided at the bottom of the sub-drawer. The sub-drawer can be pulled out together with the main drawer through the limited sliding of the pulley group and the guide piece. This kind of drawer-type locker with two or more drawers that can be linked together synchronously has better privacy when storing things, and when it is necessary to take items from multiple drawers, only the main drawer needs to be pulled out to pull out the remaining drawers together, which also improves the convenience needed in daily life.

[0026] See also Figure 1-8The utility model provides a technical solution: a drawer-type storage cabinet, a cabinet body 1, an active drawer 2 and a driven drawer 3 linked with the active drawer 2 are arranged in the cabinet body 1, the active drawer 2 and the driven drawer 3 are arranged in multiple layers in the cabinet body 1, the active drawers 2 on the same layer correspond to the driven drawers 3 on the same layer, a fixedly installed sliding frame 20 is arranged below the active drawer 2, the sliding frame 20 and the active drawer 2 are fixed by screw locking, the sliding frame 20 is provided with a first telescopic linear guide 21 connected thereto at one end, and the other end of the first telescopic linear guide 21 is fixedly connected to a layer plate 12 installed in the cabinet body 1, so when the active drawer 2 is pulled out, the active drawer 2 can be pulled out of the cabinet body 1 through the first telescopic linear guide 21, and a damping slide rail 22 is also provided on the layer plate 12, the damping slide rail 22 is just arranged below the sliding frame 20, and a buckle 220 that cooperates with the limited sliding is provided in the damping slide rail 22, and the sliding frame 20 A buffer block 221 is provided at the bottom just corresponding to the damping slide rail 22. When the active drawer 2 needs to be pushed back after being pulled out, the buffer block 221 can be mutually locked with the buckle 220 during the process of pushing the active drawer 2 back. When the buffer block 221 is locked with the buckle 220, the buffer block 221 is automatically pushed back and coupled in the damping slide rail 22, so that the buffer block 221 continues to drive the buckle 220 to slide in the damping slide rail 22. Since the drawer 20 has built-in damping, the sliding speed of the buckle 220 in the damping rail 22 will become slower and slower until it stops, thereby achieving the effect that the buckle 220 can be automatically pushed back to its original position in the damping rail 22 after the buffer block 221 and the buckle 220 are engaged. The movement speed of the active drawer 2 when it is pushed back is buffered and stopped by utilizing the engagement between the buffer block 221 and the buckle 220, thereby avoiding the active drawer 2 from being hit due to the inability to control its speed when it is pushed back.

When the active drawer 2 is pulled, the sliding frame 20 will drive the transmission rod 41 to rotate with it. At this time, the transmission rod 41 will drive the transmission plate 42 to drive the support frame 32 to work in conjunction, and after the support frame 32 is driven by the connecting rod mechanism 4, the first guide pulley 30 will slide along the path of the first guide rail 5, thereby driving The driven drawer 3 slides along the path of the first guide rail 5 to the top of the layer plate 12. When the driven drawer 3 slides to the top of the layer plate 12, since the back side of the support frame 32 is connected to the back side of the cabinet body 1, and the box body 33 is slidably matched with the support frame 32, and the second guide rail 31 at the bottom of the box body 33 and the second guide pulley 40 on the transmission plate 42 slide with each other, when the active drawer 2 continues to be pulled, the transmission rod 41 will continue to drive the transmission plate 42 to rotate, and the second guide pulley 40 on the transmission plate 42 is limited by the second guide rail 31. At this time, when the transmission plate 42 rotates, it will also drive the horizontal position of the second guide pulley 40 to change, thereby driving the box body 33 to slide along the support frame 32 and out of the cabinet The drawer 3 is pulled out of the main body 1, thereby achieving the technical effect of synchronously pulling out the boxes 33 in the active drawer 2 and the driven drawer 3. By providing a first guide rail 5 and a first guide pulley 30 at the bottom of the driven drawer 3, the first guide pulley 30 is limited and slidably cooperated with the first guide rail 5, so that the travel of the driven drawer 3 in the pulling and drawing process is more stable and smooth.
