Description

Technical Field

[0001] The utility model belongs to the technical field of slide rail drawers and relates to a three-dimensional adjuster of a drawer. Background Art

[0002] Existing high-end slide rail drawers are connected to the drawer and the slide rail by an adjustment handle, and the connection position of the slide rail can be adjusted at the same time. For example, the invention patent with patent number 201810117350.4 discloses a three-dimensional adjustment handle, including a mounting seat connected to the outer bottom of the drawer, a cover plate buckled with the mounting seat, and a locking mechanism for locking or separating the slide rail and the drawer on the mounting seat. The locking mechanism includes a spring, a handle hinged on the mounting seat, and a lock tongue that slides with the mounting seat. The front end of the lock tongue can be inserted into the lock hole of the slide rail, and the tail of the lock tongue has a connecting groove for the inner end of the handle to be inserted. The two ends of the spring are respectively against the tail of the lock tongue and the mounting seat. When the handle is turned and the handle drives the lock tongue to move backward, the spring is compressed and the lock tongue is separated from the slide rail; after the external force is lost, the spring stretches to push the lock tongue forward, so that the lock tongue is inserted into the slide rail, so that the drawer and the slide rail are locked. However, the above-mentioned locking mechanism has many parts, which is troublesome to assemble, and the structure is not firm and the stability is poor. Utility Model Content

[0003] The utility model aims to solve the above problems in the prior art and proposes a three-dimensional adjuster for a drawer, which has a stable and firm structure, few parts, simple and fast installation and disassembly, easy operation and low cost.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a three-dimensional adjuster for a drawer, comprising a metal bottom shell connected to the outer bottom of the drawer, a mounting base and a cover plate fixed on the metal bottom shell, characterized in that a locking handle is rotatably connected to the inner side of the cover plate through a pin shaft, a locking tongue is provided at the front end of the locking handle, a tension spring is connected between the middle part of the locking handle and the cover plate, the cover plate has a front stopper and a rear stopper on both sides of the tension spring, a square window for the locking tongue to pass through is opened on the edge of the cover plate, and a left-right adjustment mechanism for adjusting the left-right position of the drawer and the slide rail is also provided between the metal bottom shell and the mounting base.

[0005] Furthermore, the left-right adjustment mechanism includes left-right adjustment gears and left-right adjustment clamps. The rear ends of the left-right adjustment clamps are provided with left-right adjustment screws threadedly connected to the left-right adjustment gears. The front ends of the left-right adjustment clamps are provided with slots for the slide rail ends to be inserted into. The metal bottom shell is provided with limit slots for the left-right adjustment gears to be embedded and rotated.

[0006] Furthermore, a strip groove is formed on the upper end surface of the left and right adjustment clamps, and a limiting sliding block is provided on the mounting seat, which is inserted into the strip groove and slides along the strip groove.

[0007] Furthermore, a height adjustment mechanism that can adjust the upper and lower distances between the drawer and the slide rail is provided between the metal bottom shell and the mounting seat. The height adjustment mechanism includes upper and lower adjustment plates that slide with the mounting seat, and upper and lower adjustment gears with threaded holes. The rear end of the upper and lower adjustment plates has a height adjustment screw that cooperates with the threaded holes of the upper and lower adjustment gears, and the front end of the upper and lower adjustment plates has a working inclined surface that acts between the slide rail and the drawer bottom plate.

[0008] Furthermore, a front-to-rear adjustment mechanism for adjusting the front-to-rear position of the drawer and the slide rail is provided between the metal bottom shell and the mounting seat, the front-to-rear adjustment mechanism includes a front-to-rear adjustment seat, a front-to-rear adjustment top piece, and a front-to-rear adjustment gear. The front-to-rear adjustment seat is embedded in the mounting seat, and one side of the front-to-rear adjustment top piece is provided with a front-to-rear adjustment screw and an insertion guide bar, the insertion guide bar is embedded in the sliding hole of the front-to-rear adjustment seat, the front-to-rear adjustment gear is sleeved on the front-to-rear adjustment screw and is threadedly connected with the front-to-rear adjustment screw, and the front-to-rear adjustment seat has a gear groove for the front-to-rear adjustment gear to be embedded.

[0009] The metal bottom shell has a strong anti-collision function and can protect the internal parts. By turning the upper and lower adjustment gears, the upper and lower adjustment pieces move forward and backward, and the working bevel extends forward into the slide rail, and the drawer is raised to achieve the purpose of adjusting the gap between the drawer and the slide rail. By turning the left and right adjustment gears, it can move the left and right adjustment cards with the left and right adjustment cards, driving the slide rail to move left and right. By turning the front and back adjustment gears, the front and back adjustment top pieces move forward and backward relative to the front and back adjustment seats. When the drawer slides forward and backward, the front and back adjustment top pieces abut against the fixed rail, and the position of the drawer when it is closed can be adjusted. A square hole is opened at the front end of the slide rail, and the front end of the slide rail is inserted into the card slot, and the lock tongue passes through the square window and is inserted into the square hole under the action of the tension spring, so that the three-dimensional adjuster of the drawer is locked with the slide rail and moves synchronously, and the metal bottom shell is opened with a connection hole and connected to the bottom of the drawer by screws, so that the drawer and the slide rail can move synchronously. By manually pushing the locking handle, the drawer can be unlocked and the drawer can be separated from the slide rail.

[0010] Compared with the prior art, the three-dimensional adjuster of the drawer has the following advantages:

[0011] 1. The structure is stable and firm, with few parts, simple and fast installation and disassembly, easy operation and low cost.

[0012] 2. All three directions are adjusted and controlled by means of screws and adjusting gears. This method is simple to operate, will not be unsmooth like other transmission mechanisms, and has high adjustment accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A left-right adjustment mechanism is also provided between the metal bottom shell 1 and the mounting seat 2 for adjusting the left-right position of the drawer and the slide rail.

[0023] The left-right adjustment mechanism includes a left-right adjustment gear 11 and a left-right adjustment clamp 12. The rear end of the left-right adjustment clamp 12 has a left-right adjustment screw 13 threadedly connected to the left-right adjustment gear 11. The front end of the left-right adjustment clamp 12 has a slot 14 for the slide rail end to be inserted into. The metal bottom shell 1 has a limiting slot 15 for the left-right adjustment gear 11 to be embedded and rotated.

[0024] The upper end surface of the left-right adjustment clamp 12 is provided with a strip groove 16 , and the mounting seat 2 is provided with a limiting slider 17 which is inserted into the strip groove 16 and slides along the strip groove 16 .
