Description
Technical Field
[0001] This utility model relates to the field of fasteners, and more specifically, to a fastener suitable for quick unlocking. Background Technology
[0002] Currently, various fasteners are being adapted for different professional applications. In scenarios requiring quick fastening and disassembly, multiple sets of fasteners need to be unlocked simultaneously. Pull-type quick-release fasteners were developed specifically for such applications. US Patent No. 10595594 discloses a pull-type quick-release fastener, which uses a longitudinally inserted and secured design at both ends of the fastener. The fastening part is designed with interlocking points. Pulling to unlock involves directly pulling open the fastening part and pulling out the nested fixing part in the opposite direction. When fastening, the fasteners need to be aligned with each other, which is inconvenient. When pulling to unlock, force needs to be applied outwards and downwards simultaneously to open; other angles cannot open it, which is not conducive to combined pulling. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pull-type quick-release buckle that can be quickly fastened and released, and can be used in combination to facilitate the simultaneous unlocking of multiple sets of buckles.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] This utility model provides a pull-type quick-release buckle, including a first buckle and a second buckle; the first buckle has two symmetrically arranged first magnetic grooves, and the second buckle has correspondingly arranged second magnetic grooves. Two first magnets and two second magnets are respectively embedded in the corresponding first magnetic grooves and second magnetic grooves. The magnetic poles of the mating surfaces of the first magnets and the second magnets are opposite, and they attract each other, forming a magnetic attraction part that allows the first buckle and the second buckle to engage with each other; the first buckle has symmetrically arranged hooks, and the second buckle has symmetrically arranged hook grooves. A first fastening part is provided at the end of the hook, and a second fastening part is provided at the entrance of the hook groove. The first and second fastening parts interlock. A first guide slope is provided at the top of the first fastening part, and a second guide slope is provided at the entrance end of the second fastening part. During interlocking, the first and second guide slopes guide each other, allowing the hook body to smoothly enter the hook groove and achieve interlocking of the first and second fastening parts. A first stepped hole is provided at the root of the hook body, and a second stepped hole is provided at the bottom of the hook groove. The two stepped holes provide mold penetration positions for the forming of the first and second fastening parts, respectively. The hook body and hook groove, together with the first and second fastening parts, constitute the hook fastening part where the first and second fastening parts interlock. A transverse buckle is symmetrically arranged on the inner side of the first fastening part. The first and second fasteners have symmetrically arranged support blocks along their inner edges, and a fastening stop edge on the side of the transverse fastening groove. The support blocks and fastening stop edges together form a support reinforcement when the first and second fasteners are fastened. The first fastener has an unlocking hook in its middle section, with symmetrically arranged transmission force-bearing parts on both sides. The second fastener has an unlocking groove in its middle section. The unlocking hook includes an arc-shaped elastic arm, one end of which is fixed to the side of the middle section of the first fastener, and the other end has a transmission block, a longitudinal fastening groove, and a traction hole. The outer side of the longitudinal fastening groove has a first longitudinal fastening guide slope. The end of the unlocking groove has a longitudinal fastening rib and a second longitudinal fastening guide slope. Transmission blocks are symmetrically arranged on both sides of the unlocking groove. When the transmission block is engaged, it is inserted into the receiving groove. The first and second longitudinal buckle guide slopes guide the longitudinal buckle groove to the longitudinal buckle rib for locking. The traction rope is fixed in the traction hole. When unlocking, the traction rope can be pulled outward at any angle to separate the longitudinal buckle groove from the longitudinal buckle rib and pull the transmission block. The transmission block drives the transmission force-bearing part to deflect outward around the support block in the transverse buckle groove. The aforementioned unlocking hook and unlocking groove constitute the unlocking traction part. A first ties groove is provided on the side of the first fastener, and a second ties groove is provided on the side of the second fastener. Ties are bound in both sets of ties grooves, and the two sets of ties grooves constitute the ties binding part.
[0006] This utility model has the following advantages: the magnetic attraction method enables the two fasteners to automatically fasten under the action of the magnet, which is very convenient; in the fastened state, the hook fastening part can prevent the two fasteners from being unlocked by external force, and the fastening is very stable; when subjected to lateral tension on both sides, the hook fastening part and the support reinforcement part are subjected to force at the same time, which can meet the requirements of a very high load; when unlocking, the unlocking hook can be quickly released by pulling it outward from any angle, which can meet the needs of quick unlocking when multiple sets of fasteners are used together.
