Description

Can realize closed rebounder of door leaf buffering and cabinet door structure

Technical Field

The utility model belongs to the technical field of hardware fitting's technique and specifically relates to a can realize closed bounce-back ware of door leaf buffering and cabinet door structure.

Background

The rebounder is a switch used for furniture such as a cabinet, a drawer and the like, and after the rebounder is installed on a cabinet door, a handle is not needed when the cabinet door is opened or closed, and the door can be opened or closed only by pressing a door plate.

The prior patent with the publication number of CN216921787U discloses a rebounder capable of realizing automatic buffering closing of a door leaf and a cabinet door structure, wherein the rebounder comprises a shell; an inner support slidably disposed within and extendable out of the housing; the inner support is provided with an adjusting rod which can extend out of the shell and is used for being abutted against the door leaf in a sliding mode, and the adjusting rod and the inner support are fixed relatively through a clamping structure; a support disposed within the housing and providing a supporting force for the inner support; when the door leaf is closed, under the combined action of the closing force of the door leaf and the supporting force provided by the supporting piece, the adjusting rod can slide backwards relative to the inner support and can be fixed relatively through the clamping structure, and therefore the door leaf is closed automatically. The linkage mechanism is arranged on the inner support and comprises a transmission mechanism, a telescopic piece and a second elastic piece which are arranged on the inner support; the transmission mechanism comprises a first rack, a gear and a second rack which are sequentially meshed with each other for transmission, the first rack is arranged on the pressing block, and the second rack is arranged on the telescopic piece.

This bounce-back ware is applied to the door leaf, when closing the door leaf, this door leaf is at first contacting the regulation pole at the closing in-process, and make under the effect of door leaf closing force adjust the pole and slide backward, at this in-process, this inner support is under the effect of attenuator, motionless or slow motion, thereby make and adjust the pole and drive the briquetting and move and compress first elastic component together, when couple on this briquetting removed along the guide way, first rack on this briquetting passes through gear drive second rack and extensible member and removes and compress the second elastic component, when the couple on up this briquetting hooks the notch, this regulation pole is in the locking state, can realize the self-closing of door leaf this moment. In the process, the inner support frame is not slid in place temporarily under the action of the damping oil cylinder. After the actions are locked, the first elastic piece and the second elastic piece are both in a compression locking state, at the moment, the inner support and the shell are in an inelastic state, the inner support slides backwards along the shell under the action of closing force of the door leaf and slowly compresses the piston rod of the damper until the door leaf is completely buffered and closed, and therefore the buffering effect is achieved.

The above prior art solutions have the following drawbacks: the pressing block is linked with the telescopic piece through a first rack, a gear and a second rack, the first rack is arranged on the pressing block, the second rack is arranged on the telescopic piece, and the first rack and the second rack are both meshed with the gear; when assembling the rebounder, attention needs to be paid to the position where the gear is respectively meshed with the teeth on the first rack and the position where the gear is meshed with the teeth on the second rack; if the gear is not properly matched with the position where the gear is meshed with the teeth on the first rack and the position where the gear is meshed with the teeth on the second rack, when the adjusting rod retracts into the shell, the hook cannot hook the notch, so that the adjusting rod cannot be in a locking state, and the rebounder cannot be normally used; in addition, during installation, the gear is clamped between the first rack and the second rack and is respectively meshed with the first rack and the second rack, the structure is complex, the assembly speed is low, and the assembly speed of the rebounder is slow.
