The invention discloses a stable pressing plate fastener, and relates to the technical field of fasteners. The bolt comprises a screw and a nut, a screw head is arranged at one end of the screw, a threaded end is arranged at the other end of the screw, the nut is arranged at the threaded end in a threaded mode, a kidney-shaped opening is formed in the pressing plate, the bolt penetrates through the kidney-shaped opening, strip-shaped grooves are formed in the positions, located on the two sides of the kidney-shaped opening, of the pressing plate, and a positioning part is arranged on the inner side of the screw head of the screw. The anti-disengaging piece comprises an upper limiting plate, a lower limiting sleeve and a locking sleeve, and a positioning opening is formed in the upper limiting plate. Through the design of the anti-falling piece, the upper limiting plate can limit rotation of the screw, the lower limiting sleeve and the locking sleeve are matched to limit rotation of the nut, meanwhile, the nut and the bolt are connected and interlocked through the supporting plate, the nut and the bolt are kept in a relatively static state, and therefore the problem that a fastening point is prone to loosening due to vibration or shaking is avoided; and the stability is improved.

    本发明公开了一种稳定型压板紧固件,涉及紧固件技术领域。本发明包括压板、螺栓和防脱件,螺栓包括螺钉和螺母,螺钉一端设有螺头,螺钉另一端设有螺纹端,螺母螺纹设置在螺纹端上,压板上设有腰形口,螺栓贯穿腰形口,压板上且位于腰形口两侧的位置均设有条形槽,螺钉的螺头内侧设有定位部,防脱件包括上限位板、下限位套和锁定套,上限位板上设有定位口。本发明通过防脱件的设计,上限位板可限制螺钉的转动,下限位套和锁定套的配合可限制螺母的转动,同时通过支板进行两者之间的连接互锁,使螺母和螺栓保持相对静止的状态,从而避免振动或晃动造成紧固点易松的问题,从而提高稳定性。
