Mooring type fastening assembly

Abstract

The invention provides a mooring type fastening assembly. The mooring type fastening assembly comprises a mooring type bolt and a connecting structure. The mooring type bolt comprises an outer sleeve piece, a lock sleeve, a spring, a half ring and a bolt which are arranged on the same axis. The outer sleeve piece and the lock sleeve are cylindrical. An inner cavity of the outer sleeve piece is divided into two segments which are a first outer sleeve piece inner cavity and a second outer sleeve piece inner cavity respectively, and the inner diameter of the first outer sleeve piece inner cavity is smaller than that of the second outer sleeve piece inner cavity. An inner cavity of the lock sleeve is divided into two segments which are a first lock sleeve inner cavity and a second lock sleeve inner cavity respectively, and the inner diameter of the first lock sleeve inner cavity is smaller than that of the second lock sleeve inner cavity. The bolt sequentially comprises a screw head, a screw and a threaded end. The mooring type fastening assembly high in integration degree is provided for overcoming the defects of an existing fastener, the problems that the existing fastener is larger in number of parts and not convenient to use and preserve, and potential safety hazards exist are solved, and a good effect is achieved when the mooring type fastening assembly is applied to an auxiliary power device.

Description

technical field [0001] The present invention relates to the technical field of fasteners, and more specifically, to a captive fastening assembly. Background technique [0002] Fasteners are the most widely used mechanical fastening basic parts, among which threaded fasteners are widely used in various fields. Ordinary threaded fasteners usually include bolts and nuts, which are used in conjunction with the connected parts to Realize the fastening of the connected parts. At present, the commonly used bolt connection structure is shown in the figure below. The bolt passes through the through hole of one or more components and is screwed into the threaded hole of another component; or the bolt passes through two or After the through holes of multiple components, tighten with nuts. When assembling and using, it is necessary to completely pass the rod of the bolt through the bolt hole of the connected part, and then tighten the nut to fasten the connected part; when disassemblin...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problems of many tools, large space, long assembly and disassembly time, many parts are easy to fall, and inconvenient storage when the existing ordinary threaded fastening assembly is assembled and disassembled, and provides a tethered fastening assembly. Tighten the components to improve the integration of the product and avoid the bolts from being independent of the installation components. It is not only easy to use and install, reduces the time of installation / disassembly, improves work efficiency, but also effectively avoids the loss of bolts, washers and other parts, reducing wrong installation, The probability of incidents such as missing installation and foreign objects falling in reduces the space requirements for maintenance
