Problems solved by technology

[0003] This anti-loosening method needs to screw the nut until the screw pin hole is exposed and then install the pin. Due to the influence of the drilling accuracy (position accuracy and aperture processing accuracy) of the pin hole or the installation accuracy of the workpiece, the nut is over-tightened to install the pin, or tightened. The rear pin hole is exposed too much, and there is a gap between the pin and the end face of the nut after the pin is installed (the nut will not contact the pin to stop rotation until the nut is loosened for a certain distance), and the anti-loosening effect cannot be guaranteed
On the one hand, bolts need to be specially drilled for pin holes, which increases the manufacturing cost. On the other hand, because the gap between the end face of the nut and the pin is uncontrollable due to various factors after tightening, it affects the anti-loosening effect, so it cannot be applied to the nut of the bolt connection pair. Occasions with high anti-loosening requirements

Abstract

The invention discloses an anti-loose combined gasket and a self-adaptive locking structure for a rail, and relates to the technical field of gaskets. The anti-loose combined gasket comprises a gasket body and a rotation stopping bolt, a first through hole allowing a screw of a bolt to penetrate is formed in the gasket body in a penetrating mode, a rotation stopping boss is arranged on the end wall, where one end of the first through hole is located, of the gasket body in a protruding mode, a mounting channel is formed in the rotation stopping boss in a penetrating mode, and the rotation stopping bolt is used for being inserted into the mounting channel. The rotation stopping plug pin is used for abutting against the side wall of the nut when the nut rotates relative to the screw rod under the condition that the rotation stopping plug pin is inserted into the installation channel so as to limit screwing-in or screwing-out of the nut on the screw rod. According to the anti-loosening combined gasket, the nut can be prevented from loosening under the condition that the structures of a screw and the nut are not damaged, and the situation that the nut and the bolt can be effectively prevented from loosening without additional machining for standard bolts in various industries can be met.

Description

technical field [0001] The invention relates to the technical field of gaskets, in particular to an anti-loosening composite gasket and an adaptive locking structure for rails. Background technique [0002] At present, in the combined locking structure of bolts and nuts, the conventional practice in the machinery industry is to set pin holes through the screw rod, and insert the cotter pin into the pin hole on the screw rod after the nut is tightened in place, and restrict the nut loosening by the pin. take off. [0003] This anti-loosening method needs to screw the nut until the screw pin hole is exposed and then install the pin. Due to the influence of the drilling accuracy (position accuracy and aperture processing accuracy) of the pin hole or the installation accuracy of the workpiece, the nut is over-tightened to install the pin, or tightened. The rear pin hole is exposed too much, and there is a gap between the pin and the end face of the nut after the pin is installe...
