Safety buckle openable by special tool

Abstract

The invention discloses a novel safety buckle which is mainly applied to the field of amusement equipment, in particular to high-altitude projects. The safety buckle is divided into four main parts, namely a buckle piece, a buckle seat, a positioning block and a magnetic block, an accommodating chamber, a cavity and an opening are formed in the buckle seat, a step is arranged in the accommodatingchamber, and the opening is communicated with the accommodating chamber, and a lower bottom surface of the cavity is provided with an arc-shaped small cavity. The magnetic block and the positioning block are mounted in the buckle seat, and a cover plate is fixed on the buckle seat through a rivet to form a closed containing chamber. And the buckle piece is provided with a rectangular cavity and isconnected and fixed to a tongue plate through a rivet. The inverted-T-shaped positioning block is a lock cylinder, one side of the positioning block is a bevel edge, one end of the bevel edge of thepositioning block sinks, and the other end of the bevel edge of the positioning block is located on a step of the containing chamber, so that the situation of difficult unlocking caused by unsmooth lifting of the positioning block due to large magnet deviation during unlocking is avoided. The magnetic block is placed in the cavity of the buckle seat, and the lifting and the uplifting of the positioning block are controlled through magnetic force below the positioning block, so that the function of a key is achieved. The buckle piece and the buckle seat are connected through the positioning block, and unlocking and locking are achieved through the magnetic block and a rubidium magnet.

Description

[0001] Technical field [0002] The invention mainly relates to the fields of high-altitude operations, outdoor sports and amusement equipment, especially high-altitude and dangerous equipment. Background technique [0003] The safety buckle is also called "safety hook", "safety buckle" and so on. Safety buckles are used in automobiles, high-altitude operations, amusement equipment, suspension, lifting and other places. At present, the safety buckles we have come into contact with are all ordinary safety buckles, which can be opened without special tools, which hides a huge safety hazard. For example, a male tourist on the Huashan Plank Road suddenly untied his safety rope and jumped off the cliff, causing an irreparable mistake. [0004] There are various safety buckles on the market, but there is no special safety buckle (which can be opened by professional tools). Once the passenger opens the safety buckle at high altitude, he will fall from high altitude, causing seriou...
