The position of the connecting member 6 corresponding to the telescopic rod 32 of the damper 3 extends downward with a second limiting portion 62. The second limiting portion 62 limits the telescopic rod 32 of the damper 3 longitudinally. Run in balance to avoid bending.

The triggering part is a pendulum hook 41. The direction of the pendulum hook 41 from the head to the tail is the same as the direction of closing the door and the tail is bent downward. The second slider 4 is provided with a cavity 42 for placing the pendulum hook 41. The cavity 42 is hinged with the second slider 4 through a pin. The head of the swing hook 41 is provided with a columnar connecting piece 48, and the end of the second mounting groove 14 near the head of the swing hook 41 is provided with a first U-shaped slot 17, and the first U-shaped slot 17 is connected to the column. Piece 48 snaps on. The second slider 4 is provided with a semi-circular notch 43 at a position in contact with the pendulum hook 41 when the pendulum hook 41 swings, and a muffler soft rubber column 44 is provided on the semi-circular notch 43. The sound of the second slider 4 reduces noise.

The first slider 2 is provided with a first connection groove 21 that is cooperatively connected with the telescopic end of the damper 3, and the second slider 4 is provided with a second connection groove 45 that is cooperatively connected with one end of the elastic member 5. This connection groove is such a connection The method makes the assembly more convenient and quick, and saves the cost of the workpiece.

A support member 15 supporting the telescopic rod 32 of the damper 3 is provided in the first mounting groove 12 to make the telescopic rod 32 of the damper 3 expand and contract smoothly. A fixing position 16 is provided at an end of the second mounting groove 14 away from the second slider 4, and is used to fix an end of the elastic member 5 away from the second slider 4. A second U-shaped clamping groove 18 is laterally provided at one end of the housing 1 at the end in the closing direction. A U-shaped elastic piece 19 is mounted on the second U-shaped clamping groove 18 and plays a positioning role during installation.

One end of the connecting member 6 connected to the first slider 2 is provided with a threaded hole 63, one end connected to the second slider 4 is provided with a square hole 64, and one end connected to the second slider 4 is provided with a positioning slot 65; The top of the first slider 2 is integrally provided with a stud 22 connected to the threaded hole 63, the top of the second slider 4 is provided with a square buckle 46 interlocking with the square hole 64, and the side of the second slider 4 is provided A positioning block 47 is engaged with the positioning slot 65. Threaded holes 63 and studs 22, square holes 64 and square buckles 46, positioning card slots 65 and positioning blocks 47, these connection methods help the connector 6 and the first slider 2, the connector 6 and the second slider 4 Precise positioning during assembly, and at the same time enhance the connection strength of the sliding door buffer when working.

Guide rail grooves are provided on both sides of the first slider 2 and the second slider 4. Correspondingly, guide rails are provided on the groove walls on both sides of the first mounting groove 12 and the second mounting groove 14, so that the first slider 2 The second slider 4 and the second slider 4 can slide in balance in the first mounting groove 12 and the second mounting groove 14, respectively, to prevent the slider from jumping during operation and impacting and rubbing against other parts.

Preferably, the damper 3 is a buffer cylinder, and the elastic member 5 is a tension spring.

The invention is installed on the door frame, and the top of the sliding door 8 can be provided with a dial hook 9 corresponding thereto. When the door is closed, the dial hook 9 dials the swing hook 41 to start buffering.

The working principle of the present invention is as follows:

Before the hook member 9 on the sliding door 8 does not touch the swing hook 41, the cylindrical connecting member 48 on the swing hook 41 is snapped into the first U-shaped clamping groove 17 of the second mounting groove 14. At this time, the elastic member 5 is a stretched state, as shown in FIG. 7. When the door is closed, the pendulum hook 41 of the second slider 4 is moved to the right by the hook member 9 and the cylindrical connecting piece 48 of the pendulum hook 41 detaches from the first U-shaped slot 17, as shown in FIG. 8. 4 is pulled by the elastic member 5 and slides in the door closing direction. Because the connecting member 6 is fixedly connected to the first slider 2 and the second slider 4, respectively, the elastic member 5 pulls the connecting member 6 to move in the door closing direction, and the first slide The block 2 also slides in the direction of closing the door, and because the first slider 2 is connected to the telescopic end of the damper 3, the sliding of the first slider 2 causes the damper 3 to compress, generating cushioning resistance, and alleviating the connector 6, the first sliding The moving speed of the component composed of the block 2, the damper 3, the second slider 4, and the elastic member 5 makes the sliding door 8 close slowly and softly, and eliminates the sound produced by the sliding door striking the door cabinet.

For those skilled in the art, according to the above technical solutions and concepts, various other corresponding changes and modifications can be made, and all these changes and modifications should fall within the protection scope of the claims of the present invention.
