Description

Inner folding door structure with buffer self-closing system Technical Field The utility model relates to an inward folding door structure with a buffer self-closing system. Background The prior patent number is CN202322297058.4, the patent name is a flat-open door structure of a shower room, which comprises a track beam, a glass door and a glass clamp fixed with the glass door, and is characterized by further comprising a support rod and a sliding component, wherein the sliding component is arranged on the track beam and can slide along the track beam, one end of the support rod is rotationally connected with the track beam, and the glass clamp is rotationally connected with the other end of the support rod and the sliding component. This structure needs the manual work to go the pulling glass door and just can realize closing the door to do not have the buffering, when the excessive power, lead to the glass door to receive great collision easily, structural arrangement is unreasonable. Disclosure of Invention The utility model aims to provide an inward folding door structure with a buffering self-closing system, which solves the technical problems that in the prior art, a door can be closed only by manually pulling a glass door, buffering is omitted, the glass door is easily subjected to larger collision when the force is excessive, and the structural arrangement is unreasonable. The technical scheme of the utility model is realized as follows: The utility model provides an inward folding door structure with a buffer self-closing system, which comprises a door frame, a glass door, a pulley assembly and a connecting rod, wherein the door frame comprises a top beam, a sliding rail is arranged below the top beam, the pulley assembly comprises a connecting seat and a pulley arranged on one side of the connecting seat, the bottom of the connecting seat is rotationally connected with the glass door, the pulley is arranged in the sliding rail to slide, one end of the connecting rod is rotationally connected with the top beam, and the other end of the connecting rod is rotationally connected with the top of the glass door; When the pulley component drives the glass door to close, the connecting block on the connecting seat contacts the contact part of the buffer, and then the connecting block is clamped on the contact part and the contact part drives the connecting block to slide, so that the glass door achieves the self-closing effect. The two sides of the groove are provided with fixed blocks, and the buffer is supported on the fixed blocks at the two sides. The top beam is provided with a first hinge part, the connecting rod is rotationally connected with the first hinge part, the other end of the connecting rod is provided with a second hinge part, and the second hinge part is rotationally connected with the top of the glass door. The top of the glass door is provided with a connecting frame, the connecting frame is provided with a first hinge shaft and a second hinge shaft, the first hinge shaft is rotationally connected with the connecting seat, and the second hinge shaft is rotationally connected with the second hinge part.
