Description

a damper

【Technical field】

The utility model relates to a damper for furniture, which belongs to the household hardware manufacturing industry.

【Background technique】

I submitted a patent application titled "A New Type of Buffer" to the State Patent Office, which disclosed a new type of buffer, including a fixed plate, a damper, a damper wheel and a door mounted on the guide rail. The damper includes a housing, and a through groove is arranged in the housing, and a damping tube, a tension spring and a movable part are arranged in the through groove. The shifting block cooperates with the movable part, so as to achieve the purpose of damping and buffering.

Since the movable part needs to slide back and forth in the through slot, the movable part is limited by the size of the through slot. The thickness of the slot of the movable part is generally set below 2.5MM. Since the slot of the movable part is relatively thin, when pushing the sliding door, When the shifting block is matched with the slot of the movable part, it is easy to dislocate, resulting in the failure of the damper, so that the damping effect cannot be achieved.

【Content of utility model】

The purpose of the utility model is to provide a simple structure, which will not dislocate when the shifting block cooperates with the movable part, which is beneficial to the normal movement of the damper.

For the above purpose, the utility model adopts the following technical solutions:

A damper includes a housing, a damping tube, a tension spring and a movable part. The other end of the housing is bifurcated as an upper shell and a lower shell, and a gap is provided between the upper shell and the lower shell. The movable part is stuck in the gap, the damping tube includes a telescopic rod, and the front end of the telescopic rod is rotatably connected to the middle part of the movable part; one end of the extension spring is fixed to the bottom of the housing, and the other end is connected to the movable part The tail part is fixed; it is characterized in that the movable part is provided with a card slot exposing the outside of the shell, and the card slot is provided with an upwardly thickened front card edge and a rear card edge; a guiding chute is provided on the lower shell. The front end of the chute is provided with an arc portion bent inward, and the front end of the movable part is provided with a guide column sliding along the guide groove.

A damper as described above is characterized in that the thickness of the front card edge and the rear card edge of the card slot is set between 2.5 mm and 15 mm.

A damper as described above is characterized in that the slide groove on the lower shell is arranged outside the upper shell.

A damper as described above is characterized in that a groove with the same shape as the arc portion is provided on the upper case at the arc portion of the chute on the lower case, when the guide column of the movable part slides to the arc portion of the chute When the top of the shape part is formed, the front edge of the movable part is sunk into the groove, and the rear edge of the movable part is exposed outside the housing.

A damper as described above is characterized in that an accommodating cavity is provided at one end of the housing, and the damping tube is arranged in the accommodating cavity.

A damper as described above is characterized in that a groove is provided on the outside of the accommodating cavity, and the tension spring is arranged in the groove.

A damper as described above is characterized in that the ends of the upper shell and the lower shell are fixed by screws.

The beneficial effects of the utility model are as follows: by thickening the front edge and the rear edge of the card slot of the movable part upwards, generally between 2.5-15MM, thereby effectively preventing the shifting block on the door rail from moving from the movable part. The hazard of falling off in the card slot 9 ensures the quality of the product and is more conducive to its use, so it has more market competitiveness.

【Detailed ways】

As shown in the figure, a damper referred to in the utility model includes a housing 1, a damping tube 2, a tension spring 3 and a movable part 4, and the other end of the housing 1 is bifurcated as an upper shell 5 and the lower shell 6, the upper shell 5 and the lower shell 6 are provided with a gap 7, the movable part 4 is stuck in the gap 7, so that the movable part 4 can move in the gap 7, and the damping tube 2 includes A telescopic rod 8, the front end of the telescopic rod 8 is rotationally connected to the middle part of the movable part 4; one end of the extension spring 3 is fixed to the bottom of the housing 1, and the other end is fixed to the tail of the movable part 4; wherein the movable part 4 is provided with a card slot 9 that exposes the outer side of the housing 1, and the card slot 9 is provided with an upwardly thickened front card edge 10 and a rear card edge 11, so that the shift block on the door rail of the sliding door is not easy to move from the card slot 9. Comes off for smooth sliding door movement. A guiding chute 12 is provided on the lower shell 6, and an inwardly curved arc portion 13 is provided at the front end of the chute 12, and a guide column 14 sliding along the guide groove 11 is provided at the front end and the rear end of the movable part 4. .

In the present invention, the chute 12 on the lower shell 6 is arranged outside the upper shell 5 . On the upper shell 5, a groove 15 with the same shape as the arc portion 13 is provided at the arc portion 13 of the chute 12 of the lower shell 6. When the guide post 14 of the movable part 4 slides to the top of the arc portion 13 of the chute 12 At this time, the front edge 10 of the movable part 4 is sunk into the groove 15, and the rear edge 11 of the movable part 4 is exposed outside the housing 1 at this moment. When the sliding door is moving, the shifting block on the door track moves into the slot 9 of the movable part 4 to drive the damper to work.

In this embodiment, an accommodating chamber 16 is provided at one end of the housing 1 , and the damping tube 2 is disposed in the accommodating chamber 16 . A slot 17 is provided on the outside of the accommodating chamber 16 , and the tension spring 3 is disposed in the slot 17 .
