Abstract

The invention discloses a detachable anti-loosing component for screws. The anti-loosing component comprises a main locking piece and an auxiliary locking piece, wherein the main locking piece is in a cylinder shape, and an orthohexagonal countersunk is opened on the surface of the cylinder; a locking component group is arranged on the outer circumferential wall of the main blocking piece and comprises main locking teeth, flexible arms and shifting blocks; and the auxiliary locking piece is in a non-circular shape, a circular countersunk is arranged on the surface of the auxiliary locking piece, and auxiliary locking tooth-shaped grooves are circumferentially distributed along the outer circumference of the circular countersunk on the upper surface of the auxiliary locking piece. During mounting, the auxiliary locking piece is arranged in an auxiliary blocking piece groove of a connection board, the main blocking piece is screwed along with screws to enter the circular countersunk of the auxiliary locking piece; and when the screws are fastened, the main locking teeth are meshed with the auxiliary locking tooth-shaped grooves, and the main locking piece can only clockwise rotate corresponding to the auxiliary locking piece. The anti-loosing component of detachable screws has the advantages of being simple in structure, good in anti-loosing performance, wide in application range and convenient to mount and dismount.

Description

technical field [0001] The invention relates to a detachable screw anti-loosening assembly, which belongs to the technical field of screw fasteners. Background technique [0002] Screws, threaded rods or bolts are used to fasten two or more components together. When these threaded connections are self-locking, the friction generated on the threaded support surfaces prevents them from loosening. If the pre-tightening force is zero due to slipping, the threads cannot be pressed against each other, and the screws may loosen when they are bumped or vibrated. Therefore people have adopted different anti-loosening parts on different occasions. [0003] For example, ratchet screw nuts are used where high preload screw connections are required perpendicular to the screw axis and where the surface of the member to be fastened is not hard. For hard surfaces use a micro-sealing adhesive. Or use a form-fitting compression washer with flange or external shoulder. Or use non-detachab...
