Description

Technical Field

[0001] This utility model relates to an inward folding door structure with a buffer self-closing system. Background Technology

[0002] The existing patent, CN202322297058.4, is titled "A Shower Room Hinged Door Structure for Narrow Spaces." It includes a track beam, a glass door, and a glass clamp fixed to the door. Its key feature is the inclusion of a support rod and a sliding assembly. The sliding assembly is mounted on the track beam and can slide along it. One end of the support rod is rotatably connected to the track beam, and the glass clamp is rotatably connected to the other end of the support rod and the sliding assembly. This structure requires manual pulling of the glass door to close, lacks cushioning, and is prone to significant impact when excessive force is applied, resulting in an unreasonable structural arrangement. Summary of the Invention

[0003] The purpose of this utility model is to provide an inward folding door structure with a buffer self-closing system, which solves the technical problems of existing technology where the glass door needs to be manually pulled to close, there is no buffer, and when too much force is applied, the glass door is easily subjected to a large impact, and the structure is not reasonably arranged.

[0004] The technical solution of this utility model is implemented as follows:

[0005] This utility model provides an inward folding door structure with a buffer self-closing system, including a door frame, a glass door, a pulley assembly and a connecting rod. The door frame includes a top beam, and a slide rail is provided below the top beam. The pulley assembly includes a connecting seat and a pulley provided on one side of the connecting seat. The bottom of the connecting seat is rotatably connected to the glass door. The pulley slides in the slide rail. One end of the connecting rod is rotatably connected to the top beam, and the other end of the connecting rod is rotatably connected to the top of the glass door.

[0006] The top of the top beam has a groove, in which a buffer is installed. The top of the buffer has a slide groove, in which a sliding contact part is provided. The top of the connecting seat has a connecting block. When the pulley assembly drives the glass door to close, the connecting block on the connecting seat contacts the contact part of the buffer. The connecting block is engaged with the contact part, and the contact part drives the connecting block to slide, so that the glass door achieves a self-closing effect.

[0007] The groove described above has fixing blocks on both sides, and the buffer is supported on the fixing blocks on both sides.

[0008] The aforementioned top beam is provided with a first hinge part, and the connecting rod is rotatably connected to the first hinge part; the other end of the connecting rod is provided with a second hinge part, and the second hinge part is rotatably connected to the top of the glass door.

[0009] The glass door described above has a connecting frame at the top, and a first hinge shaft and a second hinge shaft are provided on the connecting frame. The first hinge shaft is rotatably connected to the connecting seat, and the second hinge shaft is rotatably connected to the second hinge part.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. An inward-folding door structure with a buffer self-closing system, comprising a door frame, a glass door, a pulley assembly, and a connecting rod. The door frame includes a top beam with a slide rail below it. The pulley assembly includes a connecting seat and a pulley disposed on one side of the connecting seat. The bottom of the connecting seat is rotatably connected to the glass door. The pulley slides within the slide rail. One end of the connecting rod is rotatably connected to the top beam, and the other end is rotatably connected to the top of the glass door. The top of the top beam has a groove, in which a buffer is installed. The top of the buffer has a sliding groove with a slidable contact portion. The top of the connecting seat has a connecting block. When the pulley assembly closes the glass door, the connecting block on the connecting seat contacts the contact portion of the buffer, and the connecting block engages with the contact portion, causing the contact portion to slide, thus achieving a self-closing effect for the glass door. Furthermore, the buffer also provides a cushioning effect, effectively preventing the glass door from being subjected to strong impacts. The structure is rationally arranged.
