Description

Technical Field

[0001] The utility model relates to the technical field of door frame guide rail buffer structures, in particular to a quick-disassembly and easy-maintenance buffer structure. Background Art

[0002] The door frame rail buffer is installed in the door frame rail. When the door is opened or closed, the door triggers the buffer, which plays a role in buffering and slowing down the door, reducing the impact force of the door on the door frame and reducing the noise of the door opening and closing. In the existing buffer structure, a slot with the same cross section as the buffer is opened on the door frame rail; then the buffer is inserted from one end of the slot to fix the buffer on the door frame rail. Although this installation structure is simple, after the door frame rail is installed, both ends of the rail are closed by the door frame. Therefore, once the buffer is damaged and needs to be replaced, the door frame rail needs to be removed from the door frame, which makes the buffer difficult to repair. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The utility model discloses a quick-disassembly and easy-maintenance buffer structure, which comprises an upper guide rail and a buffer; at least one guide rail groove is arranged on the upper guide rail; two baffles are arranged in the guide rail groove; the two baffles and the inner top wall of the upper guide rail form a positioning piece guide groove extending along the length direction of the upper guide rail; both ends of the buffer are detachably connected with positioning pieces; the cross section of the positioning piece guide groove matches the cross section of the positioning piece; the positioning piece is inserted into the guide groove; the positioning piece is fixed on the upper guide rail.

[0006] Furthermore, the buffer is provided with a positioning countersunk hole; the positioning plate is provided with a first threaded hole; and the first bolt passes through the positioning countersunk hole and is threadedly connected to the first threaded hole.

[0007] Furthermore, a guide rail bolt hole is provided on the upper guide rail; a second threaded hole is provided on the positioning piece; and the second bolt passes through the guide rail bolt hole and is threadedly connected to the second threaded hole.

[0008] Furthermore, a decorative strip is provided on one side of the buffer away from the positioning piece; decorative strip through holes are provided at both ends of the decorative strip; a third threaded hole is provided on the positioning piece; and a third bolt passes through the decorative strip through hole and is threadedly connected to the third threaded hole.

[0009] Furthermore, a positioning sheet hole through which the positioning sheet can pass is provided on the back of the upper guide rail; the positioning sheet hole is connected to the positioning sheet guide groove.

[0010] After adopting the above structure, the beneficial effects of the utility model are as follows: the quick-detachable and easy-to-maintain buffer structure described in the utility model has no essential difference from the prior art when using the utility model, so it is not described in detail. The buffer is connected to the upper guide rail through a positioning plate, and the buffer and the positioning plate are a detachable structure. When the buffer needs to be replaced, it is only necessary to remove the buffer from the positioning plate; the buffer of this structure does not require the upper guide rail to be removed from the door frame, the buffer is easy to disassemble and assemble, the work intensity is reduced, the damage to the door frame is reduced, and maintenance is convenient.
