The invention falls within the technical field of safety equipment, in particular relates to a magnetic lock.
The conventional non-magnetic luggage lock comprises a key and a key body, and the key is required to be inserted into the lock hole to unlock it. The conventional non-magnetic lock features a complex structure, the user needs to closely align the key with the lock hole during operation, the lock surface is easily scratched, and operation is inconvenient compared to magnetic locks.
In order to overcome the disadvantages and deficiencies existing in the prior art, the invention aims to provide a magnetic lock featuring a simple structure, which can be unlocked without requiring a key to be aligned with the lock hole, thereby increasing convenience of operation.
The invention is realized via the following technical proposal:

As shown in
Specifically, the fastener (201) is inserted into the hole (106) while the magnetic lock in the embodiment is in a locked state, and is fastened using the locking piece (105). When the magnetic lock in the embodiment is required to be unlocked, the external magnetic key (400) is fitted with the shell (101) and absorbed with the magnetic component (104) positioned in the shell (101), the magnetic component (104) drives the rotating component (103) to enter into contact with the sliding component (102) and drives the sliding component (102) to slide away from the locking piece (105), and the locking piece (105) is separated from the fastener (201) to complete the unlocking process.
In the embodiment, the magnetic lock also comprises a returning component (300) arranged in the shell (101), and the returning component (300) is positioned between the sliding component (102) and the shell (101). The returning component (300) provides thrust to the sliding component (102) whenever the locking piece (105) is fastened to the fastener (201), so the locking piece (105) is always fastened with the fastener (201) in the absence of the magnetic key (400). Preferably, a spring or two magnets are used as the returning component (300) within the included embodiment.
Specifically, the fastener (201) comprises a base (202) and an insertion hole (203) arranged on the base (202), and the shape of the insertion hole (203) is matched to the shape of the locking piece (105). In the embodiment, the opening of the through hole (106) is upward, allowing the fastener (201) to be fastened with the locking piece (105) to enable locking after the fastener (201) is inserted into the through hole (106) and the locking piece (105) is inserted into the insertion hole (203).
In addition, the first curved surface (107) is arranged on one side of the locking piece (105) close to the fastener (201), and a second curved surface (204) matching the shape of the first curved surface (107) is arranged on one side of the fastener (201) close to the locking piece (105). As the fastener (201) is constantly inserted into the hole (106), the first curved surface (107) comes in contact with the second curved surface (204) and pushes the sliding component (102) away from the through hole (106). After this, the locking piece (105) gradually detaches from the second curved surface (204) and is inserted into the insertion hole (203) after reaching the position of the insertion hole (203). The matching of first curved surface (107) and second curved surface (204) can play a guiding role in the connection of the fastener (201) and locking piece (105).
Specifically, the rotating component (103) comprises a rotating block (108) and two rotating shafts (109). The two rotating shafts (109) are arranged on either side of the rotating block (108) and are rotationally connected to the shell (101). The magnetic component (104) is arranged on the rotating block (108), a contact piece (110) is arranged at one end of the rotating block (108) close to the sliding component (102) by folding and extending downwards, and an extension component (111) for enabling contact with the contact piece (108) is installed at one end of the sliding component (102) close to the rotating block (108). The linkage between the rotating component (103) and the sliding component (102) can be realized by fitting the contact piece (110) to the extension piece (111). Preferably, the extension piece 111 should adopt an L-shaped structure and is integrated with the sliding component (102), further extending the service life of the embodiment.
A holding slot (112) is installed on the rotating block (108), and a magnetic component (104) is arranged in the holding slot (112). The holding slot (112) is arranged in the middle of the rotating block (108), and the magnetic component (104) is arranged in the holding slot (112), allowing an internal space to be conserved within the magnetic lock, further reducing the volume of the invention.
Specifically, a yielding slot (113) is arranged at the non-end position of the sliding component (102), and the rotating component (103) is positioned in the yielding slot (113). The yielding slot (113) can make the sliding component (102) give way to the rotating component (103) as it slides, thereby avoiding a collision between the sliding component (102) and the rotating component (103).
Compared with the magnetic lock described in Embodiment 1, the magnetic lock in Embodiment 2 contains no sliding component (102). The locking piece (105) is correspondingly arranged on the rotating component (103), and the opening of the through hole (106) is forward-oriented. The locking piece (105) is clamped to the fastener (201) instead of inserting the fastener (201), and the returning component (300) directly acts on the magnetic component (104). Compared with the magnetic lock described in Embodiment 1, the magnetic lock in Embodiment 2 features a more compact structure, and is suitable for other applications, such as being locked by pushing back and forth.
It should be noted that the magnetic component (104) in the above embodiments can be made of either magnets or iron. When the magnetic component (104) is made of magnets, the magnetic key (400) will be made of a magnet attracting the magnetic or iron component (104); if the magnetic component (104) is made of iron, the magnetic key (400) will be a magnet; similarly, the returning component (300) varies with its installation position. For possible installation positions of the returning component (300), please refer to
Finally, it should be noted that the above embodiments are only used to explain the technical proposal of the invention, not to limiting the scope of protection of the invention. Although the invention is explained in detail by referring to the embodiments, general technicians in this field should understand that they can modify or equivalently substitute the details of the technical proposal in the invention without deviating from the essence and scope of the technical proposal in the invention.
