Drawer height adjusting device of stealth-type slide rail

Abstract

The invention relates to a drawer height adjusting device of a stealth-type slide rail, and the drawer height adjusting device comprises an adjusting wheel and a movable rail, wherein the adjusting wheel is provided with a first rotating shaft, one end of the first rotating shaft is connected with an eccentric rotary supporting body, the other side of the eccentric rotary supporting body is provided with a second rotating shaft which is coaxial with the first rotating shaft, the upper part of the front end of the movable rail is provided with a square hole, two side walls of the square hole are respectively provided with a rotating shaft hole with an upper opening, the eccentric rotary supporting body is arranged in the square hole, the first rotating shaft and the second rotating shaft on the adjusting wheel are respectively installed inside rotating shaft holes, one side of the front end of the movable rail is also provided with an arc body, the adjusting wheel is provided with an elastic positioning salient point, a positioning adjusting structure is arranged between the arc body and the positioning salient point on the adjusting wheel, the positioning adjusting structure is an arc positioning rack which is arranged on the outer side arc surface of the arc body, the positioning salient point is matched with the arc positioning rack, and a central line of the outer side arc surface of the arc body is overlapped with the axial leads of the first rotating shaft and the second rotating shaft. By adopting the structure, the drawer height adjusting device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a drawer level height adjustment mechanism, in particular to a drawer height adjustment device for hidden slide rails. Background technique [0002] Nowadays, the hidden slide rails used in furniture, cabinets and drawers are generally used as figure 1 The height adjustment mechanism shown has the following defects: 1) the support plate 20 is connected to the movable rail 17 by spot welding, and the quality is unstable and consumes electric energy during the manufacturing process; 2) the adjustment wheel 18 and the positioning rod 19 are threaded. , turn the adjustment wheel to adjust the drawer front height. Since the thickness of the adjustment wheel is limited and thin, the threads on the adjustment wheel and the positioning rod must be made into fine threads, but the adjustment wheel must bear the weight of the drawer and the gravity of the items placed inside the drawer, so the adjustment wheel is very Easy to damage; 3)...

[0002] Nowadays, the hidden slide rails used in furniture, cabinets and drawers are generally used as figure 1 The height adjustment mechanism shown has the following defects: 1) the support plate 20 is connected to the movable rail 17 by spot welding, and the quality is unstable and consumes electric energy during the manufacturing process; 2) the adjustment wheel 18 and the positioning rod 19 are threaded. , rotate the adjusting wheel to adjust the height of the front of the drawer

Since the thickness of the adjustment wheel is limited and thin, the threads on the adjustment wheel and the positioning rod must be made into fine threads, but the adjustment wheel must bear the weight of the drawer and the gravity of the items placed inside the drawer, so the adjustment wheel is very Easy to damage; 3) The adjustment mechanism is set on one side of the slide rail, which causes a single side force on the slide rail. In the case of a full load of items placed inside the drawer, the slide rail is blocked and easily damaged; 4) The cost is high and the process is complicated
