Height adjusting mechanism for accurate positioning of drawer slide

Abstract

The invention discloses a height adjusting mechanism for the accurate positioning of a drawer slide, which comprises a connecting base which is arranged at the bottom of a drawer and detachably connected with a pull-out rail in a sliding rail component. The height adjusting mechanism is characterized in that an adjusting mechanism used for adjusting the height of the drawer is arranged on the connecting base; the height adjusting mechanism comprises a spanner or a rotating wheel arranged on the connecting base, and an adjusting block used for adjusting the height of the drawer; the spanner or the rotating wheel is in transmission connection with the adjusting block in a meshed way; and at least one section of stroke of the adjusting block is supported on the pull-out rail during the adjustment of the height of the drawer. The height adjusting mechanism has the advantages that the spanner or the rotating wheel is in transmission connection with the adjusting block in a meshed way, so that the adjusting block slides on the connecting base, the height of the drawer can be adjusted, the drawer and a cabinet are more orderly and artistically assembled, the connection compactness and strength of all components is improved through the multiple stage mesh transmission of the adjusting block, the adjusting block is rapid, accurate and stable for positioning, and rapid, accurate and stable positioning of the drawer is finally realized.

Description

technical field [0001] The invention relates to a drawer slide rail, in particular to a height adjustment mechanism for accurate positioning of the drawer slide rail. Background technique [0002] The Chinese patent document number is CN101664249, which discloses a drawer slide rail quick-installation adjustment mechanism on September 12, 2009. It includes a connecting seat arranged on the outer bottom of the drawer and connected to the drawer and the slide rail respectively. The adjustment block for adjusting the height position of the front panel of the drawer is connected with the adjustment dial. There is an adjustment wrench on one side of the adjustment dial, which is connected to the connection seat in rotation. The adjustment wrench is connected to the adjustment dial through the elastic part. There is a locking block on the side that matches the positioning of the connecting seat. The locking block is separated from the connecting seat after being pressed. One end o...

Problems solved by technology

[0003] It is said that the above structure can disengage the locking block from the coupling seat by pressing the adjusting wrench, which effectively locks the adjusting block and prevents the adjusted adjusting block from moving again; however, when the anti-retraction teeth on the adjusting dial When cooperating with the positioning teeth on the coupling seat, because one side of the positioning teeth of a unit on the coupling seat is inclined, and the other side is vertical, the inclined surface is used to facilitate the rotation of the adjustment turntable, and the vertical surface is used to position the adjustment turntable, so that the adjustment turntable will not Displacement phenomenon occurs, because of this, the adjustment block can only be positioned in a vertical direction, and the direction of the inclined surface is difficult to locate. If the load capacity of the drawer is large, or the drawer is pushed and pulled repeatedly, the anti-retraction teeth and positioning teeth will appear. Tooth removal will cause difficulty in the positioning of the adjustment block, resulting in displacement; and after the anti-retraction teeth mesh with the positioning teeth, if you want to adjust the position of the adjustment block, you must first press the locking block on the adjustment dial to make the anti-retraction teeth and the positioning teeth two The adjustment process is quite cumbersome, and in order to facilitate the pressing and rotation of the adjustment dial, the connection between the adjustment dial and the connecting seat is relatively soft, and the overall structure is loose. Long-term pressing and short rotating life
