Abstract

The invention discloses a nested bolt fastener easy to remove. The nested bolt fastener comprises a bolt, and the bolt is in contact connection with a lower thread sleeve; one end of the lower threadsleeve is fixedly connected with an extension part, and the extension part is hinged to one end of an upper thread sleeve; the upper thread sleeve and the lower thread sleeve are each provided with acavity internally, and sleeved with a rotating shaft separately and rotatably; the other end of the rotating shaft extends into the cavities, and the extension end of the rotating shaft is fixedly connected with a rotating rod; the other end of the rotating rod is rotatably connected with a sliding block, and the other end of the sliding block is slidably sleeved in a sliding sleeve; and the sidewall of the sliding block is fixedly connected with a guide rod. According to the nested bolt fastener easy to remove, a clamping part can be secured, so that the clamping part is engaged with a fixing bolt; bidirectional operation for the bolt is not required, and the installation is easy; the thread engagement slip is avoided, and the fastening effect is improved; the fastener is easy to remove,and manual rotation of the bolt is not required; and the working efficiency is improved, and damage to components is avoided.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a conveniently disassembled nested bolt fastener. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization and generalization. Therefore, some people A class of fasteners with existing national standards is called standard fasteners, or simply called standard parts; [0003] The general nuts and bolts on the market are engaged by threads, which are easy to slip during installation, and the bolts need to be operated in two directions, which is not easy to install, and also makes the fastening effect poor, and the general fasteners are not easy to disassemble, which makes disassembly complicated and time-consuming It is laborious, reduces work efficiency, and brings about the...
