Abstract

The contactless connected hidden screw includes shell body, fixed screw, screw cover connected on the shell body, graphite gasket placed in the bottom portion of the shell body, on the graphite gasket a spring is mounted, another end of spring is connected with turning block in which the permanent Nd-Fe-B magnet is set, upper end of the turning block is equipped with recessed groove, and on the upper surface of turning block a connecting screw is set, one end of the connecting screw is equipped with a projection block which can be fastened with the recessed groove on the turning block, its another end is placed in the screw cover and is screw-connected with inner screw thread set in one end of fixed screw, and the external screw-thread of the fixed screw can be single-screw or double-screw.

Description

technical field [0001] The invention belongs to a non-contact connecting invisible screw. Background technique [0002] Usually in the furniture and decoration industry, a detachable structure is often used, and a side-embedded aluminum rotating locking disc and a locking pin connected to the locking disc in parallel and in the same direction are used to form a locking system in the connection. The other end of the pin is screwed with a plastic nut vertically connected to another object to form a right-angle connection. Because the connection requires an external screwdriver to rotate and lock, the side of the locking plate exposed to the connecting plate will affect the appearance, and the connection is fitted with a rotating wedge surface, the fixed locking arm is long, the fixed nut is short and hard-fit, so there is millimeter-level tolerance when installing Error, after locking, it is easy to loosen under the action of external forces such as vibration and twisting. It...
