A tethered fastening component

Abstract

The invention provides a tethered fastening assembly, which includes a tethered bolt and a connection structure; the tethered bolt includes an outer sleeve, a lock sleeve, a spring, a half ring and a bolt on the same axis; the outer shell The piece and the lock sleeve are cylindrical, and the inner cavity of the outer sleeve is divided into two sections, which are respectively the inner cavity of the first outer sleeve and the inner cavity of the second outer sleeve, and the inner diameter of the inner cavity of the first outer sleeve is smaller than that of the second outer sleeve. The inner diameter of the inner cavity; the inner cavity of the lock sleeve is divided into two sections, which are respectively the inner cavity of the first lock sleeve and the inner cavity of the second lock sleeve, and the inner diameter of the first lock sleeve inner cavity is smaller than the inner diameter of the second lock sleeve inner cavity; The bolt includes a screw head, a screw rod and a threaded end in turn. The present invention provides a highly integrated tethered fastening assembly for the shortcomings of the existing fasteners, which solves the problems of the existing fasteners with many parts, inconvenient use and storage, and potential safety hazards. The tethered fastening assembly described in the invention is applied to an auxiliary power unit and has achieved good results.

Description

Technical field [0001] The present invention relates to the technical field of fasteners, and more specifically, to a tethered fastening assembly. Background technique [0002] Fasteners are one of the most widely used mechanical fastening basic parts. Among them, threaded fasteners are widely used in various fields. Common threaded fasteners usually include bolts and nuts, which are used in conjunction with the connected parts. Realize the fastening of the connected parts. At present, the commonly used bolt connection structure is shown in the following figure. 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 them with nuts. When assembling and using, the rod of the bolt needs to be completely passed through the bolt hole of the connected part, and then tightened by the nut to fasten the connected part; when disa...

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
