The utility model discloses a kind of high-strength framework structures of solid wood composite door, including door body, upper frame and lower frame are separately provided on door body, outer frame and inner frame are separately provided on the both sides of door body, rectangular tubular crosspiece is equipped in the middle of outer frame and inner frame, fixed block is equipped in the middle of crosspiece, threaded hole is vertically equipped in the middle of fixed block, main support rod is equipped in threaded hole, a plurality of I wheels are equipped on the main support rod of crosspiece up and down, vice support rod connection inner frame and outer frame are equipped on the both sides of I wheel.The utility model has the beneficial effects that: the high-strength framework structure of solid wood composite door of the utility model utilizes the design of advanced metal and wood combination, guarantees the appearance and firmness of door body, provides excellent compression resistance, corrosion resistance and deformation resistance performance;The utility model improves the strength and stability of door body in compression resistance, bending resistance, tensile resistance and other aspects by optimizing internal support frame, reasonably distributing stress, selecting high-strength material and strengthening connecting part.

The utility model discloses a transparent high-strength glass cover plate, and belongs to the technical field of glass cover plates. A transparent high-strength glass cover plate comprises a buffer supporting assembly, a front cover plate assembly and a rear cover plate assembly, the front cover plate assembly comprises an aluminum alloy framework, and the risk that the glass cover plate is deformed and damaged due to uneven stress when the front portion of the glass cover plate is impacted is reduced through aluminum; the overall bending strength of the glass cover plate can be further improved through the aluminum alloy framework and the chemically strengthened glass, the protection comprehensiveness of the glass cover plate is better than that of an existing glass cover plate, edge impact and front impact of the glass cover plate can be effectively buffered better, and the overall impact strength of the glass cover plate is improved.

A wristband with segments made of a rigid material. The present invention relates to a wristband (1) comprising: a first row (8) having at least one central segment (2); a second row (9) and a third row (10) respectively disposed on both sides of the first row (8) and each including at least one side segment (3); a connecting rod (4) positioned in three aligned holes in the first, second and third rows, the wristband (1) being characterized in that the connecting rod (4) includes a shoulder (5), and wherein each hole (2a) of the central segment (2) leads at one of its ends to a cutout (6) formed in the central segment (2), the cutout (6) being defined by a first wall (6b) and a second wall (6c), the first wall (6b) and the second wall (6c) serving as a first limiter and a second limiter for the shoulder (5) when the central segment (2) pivots about the connecting rod (4), thereby limiting the range of rotation of the central segment (2) about the connecting rod (4).
