Problems solved by technology

[0004] However, because the replacement and maintenance of the workpiece is carried out in a radiation environment, the operator cannot directly operate the nuts and bolts in the existing fastening device, and can only operate the nuts and bolts in the existing fastening device with the help of operating tools. The remote control operation of bolts and nuts, on the one hand, makes the bolts and nuts in the existing fastening device rigidly impacted when they are rigidly joined, and the first thread is prone to damage during multiple joints, which leads to the inability of the bolts and nuts to join. On the one hand, the bolts or nuts in the existing fastening devices are easy to fall due to the inflexible movement and visual obstruction due to the remote maintenance operation, so the safety of the disassembly and fastening of the existing fastening devices is extremely poor

Embodiment Construction

[0026] In order to describe the technical content and structural features of the present invention in detail, the following will further explain in conjunction with the embodiments and the accompanying drawings.

[0027] See Figure 1 to Figure 7 The fastening device 100 that can be used in remote maintenance of the present invention is used to fix the workpiece 200 on the support 300, wherein the fastening device 100 that can be used in remote maintenance of the present invention includes a screw 10, a nut structure 20, and a stop 出Component 30. The rear end of the screw 10 has a rotating block 11. Specifically, in this embodiment, the rotating block 11 is fixed to the rear end of the screw 10 by a screw 13 so that the rotating block 11 is on the screw 10 The installation of the screw 10 and the installation of the screw 10 on the workpiece 200; and the front end of the screw 10 passes through the workpiece 200. Specifically, the workpiece 200 is provided with a through hole 210 ...

Abstract

The invention discloses a fastening device applicable to remote-control maintenance, which comprises a screw rod, a nut structure and a stopping component; the rear end of the screw rod is provided with a rotating block and the front end of the screw rod passes through a workpiece and is provided with a threaded connecting part which is connected with the nut structure; an accommodating cavity is arranged on the nut structure; the stopping component is engaged and connected with an inner wall of the accommodating cavity by means of rotating relatively; the rear end of the stopping component stretches out of the nut structure and is connected with the screw rod to prevent the nut structure from screwing out of the threaded connecting part, and a supporting piece is provided with a containing cavity and a rotating cavity which are communicated and in cross arrangement. The nut structure is rotated to drive the rotating block to rotate in the rotating cavity by the stopping component until the rotating block props against an inner wall of the rotating cavity when the rotating block is arranged in the accommodating cavity and corresponds to the rotating cavity, so that the stopping component slips relative to the inner wall of the accommodating cavity and the nut structure rotates relative to the stopping component, thereby screwing the nut structure in the threaded connecting part and connecting the workpiece on the supporting piece in this way, the safety in detaching and fastening is guaranteed.

Description

Technical field [0001] The invention relates to a fastening device, in particular to a fastening device that can be used in remote maintenance. Background technique [0002] In all walks of life, we can see a fastening device composed of a screw and a nut everywhere. With the help of the fastening device, the operator can realize a detachable connection between the two workpieces, thereby facilitating the rapid replacement of the workpiece when it is damaged. The purpose of maintenance. [0003] Among them, when the workpiece to be fixed with the existing fastening device in a radiation environment is damaged and needs to be replaced and maintained, the operator at this time first uses an operating tool to separate the bolt and nut in the existing fastening device ; Next, the operator uses the operating tool to take out the damaged workpiece and nut; then, the operator then makes the new workpiece pass through the bolt of the support; finally, the operator uses the operating tool ...
