Description

Drawer guide rail pressing rebounding device

Technical Field

The utility model relates to a hardware fitting specifically is a drawer guide rail presses bounce-back ware.

Background

At present, drawer guide rails are installed on the drawers of various desks to slide freely. In order to ensure that the drawer can be tightly attached to the desk after being closed, the desk is neat and beautiful. The method in the prior art adopts a self-closing angle type guide rail with international general design, a section of guide rail which is slightly inclined downwards is arranged at the rear end of a fixed rail, and a front roller of a sliding rail arranged on a drawer automatically slides downwards under the action of dead weight when the front roller travels to the inclined section, so that the drawer is ensured to be completely closed. However, the self-closing angle type guide rail has the following disadvantages: 1. when the roller of the sliding rail is pushed to the lower sliding end, the roller only slides down along an inclined plane with the angle of 3.5 degrees to the lower degree by the self weight of the drawer, the lower sliding is not obvious to close, and the using effect is not ideal; 2. due to the small bending angle, when the drawer is slightly inclined outwards, the drawer can slide out and fall to the ground; 3. due to the structure, when the fixed slide rail is bent, the connection at the bending point cannot be smooth, so that the drawer always has the feeling of going up and down when being pushed and pulled, and the requirement of a user is difficult to meet; 4. because the drawer has no self-locking function, when the desk is moved, the drawer is easy to slide out under the action of the dead weight, so that the desk is inconvenient to move.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. A drawer guide rail pressing rebounding device comprises a base 3 and a first protective cover 61 which are buckled with each other, wherein a first hook 62 is hinged to the base, a first guide rail 63 is arranged in the first protective cover 61, a first rebounding slide block 64 is installed on the first guide rail 63 to slide, a second hook 65 is arranged at one end, butted with the first hook 62, of the first rebounding slide block 64, the first hook 62 can be buckled with or separated from the second hook 65, a first tension spring 66 is arranged between the first rebounding slide block 64 and the first protective cover 61, the first tension spring 66 pulls the first rebounding slide block 64 towards the closing direction all the time, and the inner end of the first rebounding slide block 64 is abutted against a rebounding hanging block 4; the inner side of the first rebounding slider 64 is further provided with a first slide way 67, a first driving strip 68 is installed in the first slide way 67, the outer end of the first driving strip 68 is pressed against a driving block located on the first hook 62, and the inner end of the first driving strip 68 protrudes out of the inner end face of the first rebounding slider 64 and can be in contact with the rebounding hanging block 4, so that the first driving strip 68 and the first rebounding slider 64 are displaced, and the first hook 62 is driven to deflect and be separated from the second hook 65.

The rear end of the first rebounding slider 64 is provided with a rebounding driving block 5, and the rebounding driving block 5 extends out of the first protection cover 61.

The first rebounding slide block 64, the second hook 65 and the rebounding driving block 5 are integrally made of plastic materials.

First couple 62 install on first protecting cover 61 through pivot 611 is articulated, install the torsional spring in the pivot, the first couple 62 tail end of torsional spring drive is the upswing all the time for first couple 62 is hung with second couple 65 and is detained.

The base 3 is fixed on the movable slide rail 2 of the drawer guide rail, and the rebound hanging block 4 is arranged on the fixed rail 1 of the drawer guide rail.

The bounce hanging block 4 is provided with a mute rubber 41, and the mute rubber 41 is arranged on the contact end surface of the bounce hanging block 4.

The working principle is as follows: when a user presses the guide rail to open the guide rail, the power of the pressing on the guide rail forces the tail end of the first driving strip 68 to press the rebound catch 4, and when the guide rail is pressed, the first driving strip is forced to displace with the first rebound slider 64, and the first driving strip 68 drives the first hook 62 to deflect and separate from the second hook 65. At this time, the first extension spring pulls the first rebound slider 64 to move, thereby playing a role of rebounding open the drawer rail. When the user closed the guide rail, the user can directly push the guide rail with the hand and close, also can make the guide rail close under buffering resetting means's effect, and when the guide rail was closed, bounce-back drive block promoted first bounce-back slider and moved to first couple 62 direction, forces first couple 62 and second couple 65 to hang and detain, plays the effect to the reset of bounce-back drive block and locking guide rail, opens for rebounding next time and provides basic condition.
