The three-dimensional adjusting device for the drawer and the guide rail thereof comprises a base body 1 used for connecting the drawer and a guide rail installation body 2 arranged on the base body 1 and used for connecting the guide rail, wherein the guide rail installation body 2 can move back and forth relative to the base body 1, and a front and back adjusting driving structure used for driving the guide rail installation body 2 to move back and forth relative to the base body 1 is arranged between the base body 1 and the guide rail installation body 2 so as to adjust the front and back relative positions of the drawer and the guide rail.
Specifically, the base body 1 is provided with a front and rear adjusting thread 30, the guide rail mounting body 2 is provided with a front and rear adjusting screw 32 engaged with the front and rear adjusting thread 30, and the front and rear adjusting screw 32 is provided with a front and rear sliding part 34 capable of driving the guide rail mounting body 2 to move front and rear. The front and rear adjusting screw 32 is rotated, and the front and rear adjusting screw 32 moves along the axial direction, so that the front and rear sliding part 34 drives the guide rail mounting body 2 to move back and forth. The base body 1, the guide rail installation body 2 and the front and back adjusting driving structure form a front and back adjusting structure for the drawer and the guide rail thereof, and the front and back adjusting structure is driven and slides in a screw thread and screw rod matching mode, and the front and back sliding and rotating part 34 can adjust the front and back relative positions of the drawer and the guide rail, so that stable stepless adjustment can be realized.
Further, be equipped with on the base body 1 cover in the front and back thread groove 31 of transferring on the screw rod 32 around, the front and back screw thread 30 is multistage circular-arc distributes in the front and back thread groove 31 of transferring, the front and back screw thread groove 31 with the guide rail installation body 2 forms the front and back passageway of transferring, the front and back screw rod 32 of transferring stretch into in the front and back passageway of transferring and with the front and back screw thread 30 meshes mutually. The installation of front and back accent thread groove 31 need not carry out the installation of axial screw-in from the screw thread entry end, it takes from the mounting means of radial cover to transfer thread groove 31 around, has remain the screw thread screw rod cooperation and has adjusted stable advantage, and it is more convenient to install.
Of course, the front and back channel can be formed by splicing a plane of the guide rail installation body 2 and the front and back adjusting thread groove 31, and more preferably, the guide rail installation body 2 is provided with an arc-shaped limiting notch 39, and the limiting notch 39 and the front and back adjusting thread groove 31 are staggered and intersected to form the front and back channel. The circular arc-shaped limiting notches 39 can more stably limit the front and rear adjusting screw rod 32 in the front and rear adjusting thread groove 31, so that the rotation adjustment is more stable and sensitive.
In order to realize that the front and rear sliding and rotating parts 34 drive the guide rail installation body 2 to move back and forth, the guide rail installation body 2 is provided with front and rear clamping adjusting holes 33, the front and rear sliding and rotating parts 34 are parts extending outwards along the radial direction of the front and rear adjusting screw rods 32, and the front and rear sliding and rotating parts 34 partially extend into the front and rear clamping adjusting holes 33. Specifically, the front and rear sliding-rotating portion 34 may be a cylinder having a larger diameter than the front and rear set screw 32, and a partial edge of the periphery thereof is located in the front and rear set hole 33. So that the front and rear sliding and rotating parts 34 can still drive the guide rail mounting body 2 to move back and forth.
Accordingly, the radial surfaces of the front and rear sliding-rotating portions 34 protrude from the lower surface of the base body 1. The front and rear sliding portions 34 are provided at the rear ends of the front and rear adjusting screws 32. And the front and rear sliding-rotating parts 34 are provided with vertical protrusions in a circumferential array. The vertical protrusion makes the friction force larger, the dial easier and the touch feeling better when the front and rear sliding portions 34 are dial by hand.
