Hinge assembly, folding ladder and combined guide rail crawling ladder
The invention relates to the technical field of guide rail crawling ladders, and provides a hinge assembly, a folding ladder and a combined guide rail crawling ladder.The hinge assembly comprises a first hinge piece, a second hinge piece and a hinge component, and the hinge end of one of the first hinge piece and the second hinge piece is provided with a first positioning hole and a first positioning groove; a second positioning hole is formed in the hinged end of the other one; the hinging part comprises a hinging shaft, a shaft sleeve, an elastic part, a limiting part and a positioning part, and the shaft sleeve is arranged on the outer side of the hinging shaft in a sleeving mode and fixedly matched with the hinging part provided with a first positioning hole and a first positioning groove; the elastic piece is located between the hinge shaft and the shaft sleeve. The limiting part and the matching part are matched for limiting; the positioning part is fixedly arranged on the hinge shaft and suitable for moving along with the hinge shaft so that the positioning part can be inserted into the first positioning hole and the second positioning hole in the unfolded state and can be inserted into the first positioning groove and the second positioning hole in the folded state. The guide rail ladder stand is novel in structural design and convenient to assemble on site when being applied to the guide rail ladder stand.
本发明涉及导轨爬梯技术领域，提供一种铰链组件、折叠梯子及组合式导轨爬梯，铰链组件包括第一铰接件、第二铰接件和铰接部件，第一铰接件和第二铰接件中一者的铰接端上设有第一定位孔和第一定位槽，另一者的铰接端上设有第二定位孔；铰接部件包括铰接轴、轴套、弹性件、限位部件和定位部件，轴套套设于铰接轴的外侧，并与设有第一定位孔和第一定位槽的铰接件固定配合；弹性件位于铰接轴和轴套之间；限位部件和配合部相配合进行限位；定位部件固定设于铰接轴，适于随铰接轴运动，以在展开状态下，插设至第一定位孔和第二定位孔，以在折叠状态下，插设至第一定位槽和第二定位孔。本发明的结构设计新颖，应用在导轨爬梯时，方便其进行现场装配。
