Anti-theft claw type nut

Abstract

The invention discloses an anti-theft claw type nut. The anti-theft claw type nut comprises a chassis, locking teeth and a cylinder body. The cylinder body comprises a lower cylinder body and an uppercylinder body, a first through hole is formed in the lower cylinder body and the upper cylinder body in a penetrating mode, and an inner thread is arranged on the inner wall of the first through holeof the lower cylinder body. A second through hole corresponding to the first through hole is formed in the center of the chassis, the cylinder body is fixed to the center of the top face of the chassis, and the locking teeth are fixed to the edge of the top face of the chassis in a surrounding mode. Nuts struck into a board are firmly embedded in the board and cannot be rotated by arranging a plurality of locking teeth with flanges and rough surfaces on the chassis; the nuts are doubly fixed by screwing tapping screws in to a third through hole; by arranging a through groove on the upper cylinder body 32, the upper cylinder body is drilled and blossomed by corns nails to fix the board on the other side of the board treply; and the bolts are prevented from being screwed out by arranging anabutting piece inside the second through hole of a bottom plate and using the abutting piece to abut against the blots to be screwed into the inner cylinder body, and the anti-loose and anti-theft functions are achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of nuts, in particular to the technical field of anti-theft claw nuts. 【Background technique】 [0002] The four-claw nut is a kind of furniture nut that is stronger than the general wood inlaid nut. Its four claws are symmetrically distributed, and the claw nails can effectively hold the wood. The four-claw nut is widely used in furniture installations such as sofas, beds, cabinets, desks, etc. For wooden household items such as wooden household items, usually the nuts will rotate due to various reasons during the installation of household items, resulting in difficulty in installation, while the four-claw nuts are pre-embedded on the wooden board through claw nails, and then screwed into the screws to fix the wooden board, reducing the number of ordinary nuts. The defect of spinning, but ordinary four-claw nuts do not have anti-theft function, and the screwed-in bolts can be easily unscrewed to be disasse...

[0002] The four-claw nut is a kind of furniture nut that is stronger than the general wood inlaid nut. Its four claws are symmetrically distributed, and the claw nails can effectively hold the wood. The four-claw nut is widely used in furniture installations such as sofas, beds, cabinets, desks, etc. For wooden household items such as wooden household items, usually the nuts will rotate due to various reasons during the installation of household items, resulting in difficulty in installation, while the four-claw nuts are pre-embedded on the wooden board through claw nails, and then screwed into the screws to fix the wooden board, reducing the number of ordinary nuts. The defect of spinning, but ordinary four-claw nuts do not have the anti-theft function, and the screwed-in bolts can be easily unscrewed to be disassembled by criminals
