Description

Buffering damping device for furniture hanging sliding door

Technical Field

The utility model relates to the field of buffering damping devices, in particular to a buffering damping device for a furniture hanging sliding door.

Background

Since a general large-sized sliding door is heavy, there is a possibility that the sliding door collides with the door-closing side end portion due to a strong impact force caused by its potential force when the sliding door starts to move. This condition can reduce the quality of the furniture. In order to prevent the collision state when the door is closed on the door closing side of the sliding door, the potential force when the sliding door is closed is as weak as possible, which tends to cause the sliding door to be not tightly closed. This is also responsible for the reduced quality of the furniture. Therefore, the damper (buffer) is generally used on the hanging sliding door of the existing furniture, and the shifting block for shifting the damper is arranged in the upper rail of the hanging sliding door, when the sliding door is pushed to the side, the shifting block is clamped on the movable piece of the damper to drive the hanging sliding door to slowly move until the hanging sliding door is stopped beside the frame of the door, and due to the buffer reset effect of the damper, the hanging sliding door can not collide when approaching the frame, so that noise is prevented from being generated due to collision, and even the hanging sliding door is prevented from being damaged due to collision, so that the hanging sliding door is quite popular with consumers.

As disclosed in patent No. CN208202932U, a lower wheel buffer of a sliding door comprises a buffer rod, a release claw and a spring, wherein a release claw pin shaft is arranged at the right position of the buffer deflection groove; one end of the buffer rod is arranged in the buffer outer tube, and the other end of the buffer rod is hinged with the release claw through the release claw pin shaft; the spring is arranged in the spring mounting groove, one end of the spring is clamped in the spring mounting groove, and the other end of the spring is clamped in the right bayonet of the spring. In the structure, the head end of the buffer rod is directly hinged with the release claw, the length of the shell is at least set to be the sum of the length of the buffer rod and the movement travel of the release claw, and the shell is longer and is not applicable to door leaves with smaller width; in addition, the buffer rod is hinged with the release claw, so that the buffer rod and the release claw are easy to unhook and lock in the operation process of the release claw, and the use is unstable.

Referring to fig. 3, when the cabinet door is in a closed state, under the action of the return spring 5, the striker 4 pushes the poking needle on the cabinet door to the end through the buckling groove 403, so that the door panel is in a closed state. Referring to fig. 6, when a user needs to open the door, the door is pushed, and the striking pin on the door drags the striking block 4 and the sliding piece 2 to move towards the head end of the damping rod 3, and simultaneously stretches the damping rod 3 and the return spring 5. When the plunger 4 moves to the tail end of the straight guide groove 105, the swing shaft 401 on the plunger 4 enters the disengaging groove 106, so that the plunger 4 deflects and is disengaged from the poking needle, and the poking needle and the cabinet door can be completely opened. Since the escape groove 106 is arranged perpendicular to the straight guide groove 105, the striker 4 can be caught in the escape groove 106 without being reset by the reset spring 5. When the door is closed, a user only needs to push the door plate, so that the poking needle is installed on the door plate to collide with the buckling groove 403 on the collision block 4, the collision block 4 deflects and swings out from the separation groove 106 to hang the door plate with the poking needle again, and under the action of the reset spring 5 and the damping rod 3, the door plate is slowly driven to move to the door edge by the collision block 4, so that the reset buffering effect is realized.

The same and similar parts of the embodiments in this specification are all referred to each other, and each embodiment focuses on the differences from the other embodiments.
