Embodiment Construction

[0024] The present invention will be further described below in conjunction with the drawings and embodiments.

[0025] In order to solve the problem of unilateral assembly, the technical solution adopted by the present invention is to change the ordinary nut to be composed of two smooth half rings, and the outer contour of the half rings can be polygonal or circular. The half-ring nuts are connected by a short shaft. The two half-rings can be opened into an "S" shape but will not separate. There is a groove with the same contour as the protruding disc at the end of the screw on one side of the two half-rings, which is used for the bolt body Positioning. There are threads on the screw rod body, one end has a protruding disc with a diameter slightly larger than the rod body, and the other end has a section of the rod body at the end that reduces in diameter to become a rod end connector to facilitate the connection between the installation tool and the rod body. The connection meth...

Abstract

The present invention relates to a one-way bolt and nut fastener and its mounting method, belonging to the field of mechanical assembly technology. It is characterized by that the described screw bolt and nut are specially-designed, said nut is formed from two halt-rings, between said two half-rings a short shaft is connected, said two half-rings can be combined together and formed into a 'S' form, also can be closed into a ring form. One end of said screw bolt has a projected disk for positioning nut, and one side of said nut has a recessed groove identical to the projected disk profile, said recessed groove can be used for positioning said screw bolt body. Said invention also provides its special mounting tool, and also provides its concrete mounting method and steps.

Description

Technical field [0001] The invention relates to a bolt fastener capable of unidirectional fastening from one side and an assembly method thereof, belonging to the technical field of mechanical assembly. Background technique [0002] The usual bolt fasteners are generally composed of nuts and screws. During installation, you need to clamp the nut or nut on one side, and tighten the nut or nut with a wrench from the other side. Under normal circumstances, the installer can touch the two sides of the object. But for special applications, such as closed tubular structures or structures with one end inaccessible, the use of ordinary bolts is greatly restricted. Summary of the invention [0003] In order to overcome the disadvantage that the existing bolts cannot be fastened from one side, the present invention provides a bolt fastener capable of unidirectional fastening from one side and an assembly method thereof. The performance of the fastener is similar to the existing ordinary b...
