Description

Magnetic fastening device

Technical Field

The present invention relates to a fastening device, particularly to a lock for bicycle locks, padlocks, etc., and also to a fastening device which is used for various daily articles such as bags, backpacks, boxes, etc., and detachably connects two components.

Background

The prior art fastening device (such as various locks and cases) has a disadvantage in that when inserting the plug into the fastening device, the plug is often required to be accurately aligned with the insertion hole of the fastening device, and then a certain force is required to be exerted to insert the zipper head into the insertion hole of the fastening device, so that it is inconvenient to use. Particularly, when the locking device is locked, the user may not be in a state of conveniently moving both hands, and thus the locking device which cannot be easily locked is in need of improvement.

Disclosure of Invention

In view of the foregoing disadvantages and drawbacks of the prior art, the present invention provides a magnetic fastening device that can be easily fastened.

To achieve the above object, the present invention provides a magnetic latch device, comprising:

a first seat having a plug hole;

a plug capable of being inserted into the plug hole of the first seat along a buckling direction;

the second seat can rotate relative to the first seat to enable the plug to enter a buckling state, and can rotate reversely relative to the first seat to enable the plug to change into an unlocking state;

a first component arranged on the plug;

the second component is arranged on the second seat; when the plug is inserted into the first seat along the buckling direction, a magnetic attraction force exists between the first assembly and the second assembly to enable the second seat to rotate so that the plug enters the buckling state.

To achieve the above object, the present invention further provides a magnetic fastening device, which comprises:

a first seat having two plug holes;

two plugs which can be inserted into the two plug holes of the first seat along a buckling direction respectively;

two second seats which correspond to the two plugs respectively; each second seat can rotate relative to the first seat to enable the corresponding plug to enter a buckling state, and can rotate reversely relative to the first seat to enable the corresponding plug to be changed into an unlocking state;

two first components which are respectively arranged on the two plugs;

the two second assemblies are respectively arranged on the two second seats; when the plug is inserted into the first seat along the buckling direction, a magnetic attraction force exists between the corresponding plug and the first assembly and the second assembly on the second seat to enable the second seat to rotate so that the plug enters the buckling state.

When the plug is used, when the plug is close to the plug hole of the first seat, the magnetic attraction between the first component on the plug and the second component of the second seat can play a certain guiding role, so that the plug is closer to the plug hole of the shell and tends to be inserted, and the plug is assisted to be inserted; then when the plug is inserted to the positioning, the magnetic attraction between the first component and the second component can also assist to keep the invention in a buckling state, so that excessive buckling structures are not needed to be designed, the force application required by a user can be reduced, or even the user can position and buckle the plug through the magnetic attraction without applying force; therefore, the invention not only facilitates the insertion of the guide plug, but also effectively reduces the force application of a user through the magnetic attraction between the first component and the second component, thereby greatly improving the convenience in use.

The magnetic buckling device is further improved in that when the second seat rotates reversely relative to the first seat so that the plug is changed into the unlocking state, the second seat pushes the plug to push the plug out of the plug hole of the first seat.

The magnetic buckling device is further improved in that the magnetic buckling device further comprises an operating piece which can rotate relative to the first seat, and the second seat can be rotatably arranged on the operating piece; when the plug is in the buckling state, the rotation of the operating element relative to the first seat can enable the second seat on the operating element to be separated from the plug, so that the plug enters the unlocking state.

The magnetic buckling device is further improved in that a stopping part is arranged on the first seat, a second seat actuating part is arranged on the second seat, and a plug actuating part is arranged on the plug; when the plug is inserted into the first seat, the second seat rotates to enable the second seat actuating part to be matched with the plug actuating part so as to enable the plug to enter the buckling state, and the stopping part abuts against the second seat at the moment so as to enable the plug to keep the buckling state; when the operating element rotates relative to the first seat, the second seat on the operating element is separated from the stopping part, and the second seat actuating part on the operating element is matched with the plug actuating part to cause the second seat to rotate reversely to be separated from the plug.

The magnetic buckling device is further improved in that the second seat actuating part is a lug with an arc inclined plane, and the plug actuating part is a groove with an arc inclined plane.

The magnetic buckling device is further improved in that a first seat actuating part and a rotation stopping part are arranged on the first seat; when the plug is inserted into the first seat and the second seat rotates, the rotation stop part of the first seat is abutted against the second seat to enable the plug to keep the buckling state; when the operating member rotates relative to the first seat, the second seat on the operating member is matched with the actuating part of the first seat, so that the second seat is separated from the rotation stopping part of the first seat.

The magnetic buckling device is further improved in that in the rotating process of the operating piece relative to the first seat, the operating piece pushes the plug so as to push the plug out of the plug hole of the first seat.

The magnetic buckling device is further improved in that the magnetic buckling device further comprises a control component, and the control component selectively prevents the operating component from rotating relative to the first seat and further prevents the second seat from rotating away from the plug so as to prevent the plug from entering the unlocking state.

The magnetic buckling device is further improved in that the magnetic buckling device further comprises an operating piece which can rotate relative to the first base, and the rotation of the operating piece relative to the first base can simultaneously drive the two second bases to rotate relative to the first base so as to enable the two plugs to enter the unlocking state.

Detailed Description

The technical means adopted by the invention to achieve the predetermined creation purpose is further described below by combining the accompanying drawings and the preferred embodiments of the invention.

Referring to fig. 1 to 3, a first embodiment of the magnetic fastening device of the present invention includes a first base 10, two plugs 20, two second bases 30, two first components 41, two second components 42, and further includes an operating component 50 and a control component 60.

The first housing 10 has two plug holes 13, in this embodiment, the first housing is in the form of a housing and preferably includes a base 11 and a cover 12, and the plug holes 13 are formed in the cover 12, but not limited thereto.

The two plugs 20 can be inserted into the two plug holes 13 of the first socket 10 along a locking direction.

Referring to fig. 2, 3 and 7, the two second bases 30 can rotate relative to the first base 10 to respectively enable the two plugs 20 to enter a buckling state (as shown in fig. 7), and the two second bases 30 can rotate in opposite directions relative to the first base 10 to respectively enable the two plugs 20 to be changed into an unlocking state.

Referring to fig. 4, 6 and 7, the two first components 41 are respectively disposed on the two plugs 20. The two second assemblies 42 are respectively disposed on the two second seats 30. When each plug 20 is inserted into the first socket 10 along the engaging direction, a magnetic attraction force is generated between the first component 41 of the plug 20 and the corresponding second component 42 of the second socket 30 to rotate the second socket 30 so as to bring the plug 20 into the engaging state. In this embodiment, after the magnetic attraction force rotates the second seat 30, the second seat 30 penetrates through the plug 20, so that the plug 20 cannot be separated from the first seat 10, and the plug 20 enters the fastened state.

One of the first component 41 and the second component 42 may be a magnet and the other may be a metal, or both may be magnets, so long as a magnetic attraction force is generated between the two.

In addition, the first component 41 and the second component 42 may be independent components or may be directly integrated on the components, for example, the first component 41 may be integrated with the plug 20, so that the plug 20 itself is a magnet or a metal, and the second component 42 may be integrated with the second seat 30, so that the second seat 30 itself is a magnet or a metal.

Referring to fig. 2, 3 and 6, the second seat 30 can rotate relative to the first seat 10, specifically, the second seat 30 can be directly and rotatably disposed on the first seat 10 (as shown in fig. 19), or alternatively, as in the first embodiment, the second seat 30 can be rotatably disposed on the operating element 50, and the operating element 50 can be rotatably disposed on the first seat 10, so that the second seat 30 can still rotate relative to the first seat 10. The rotation axes of the operating member 50 and the first seat 10 and the second seat 30 and the operating member 50 are not parallel, and preferably, the two rotation axes are perpendicular to each other. In addition, the rotation of the operating member 50 with respect to the first seat 10 is hereinafter referred to as lateral rotation, but the specific direction is not limited to the lateral direction. In addition, an elastic component may be disposed between the operating element 50 and the first seat 10, or an elastic structure is disposed on the first seat 10 to push the operating element 50, so that the operating element 50 keeps rotating laterally relative to the first seat 10.

When the plug 20 is in the locked state, the lateral rotation of the operating element 50 relative to the first seat 10 drives the second seat 30 on the operating element 50 to disengage from the plug 20, so that the plug 20 enters the unlocked state, and in a preferred embodiment, the lateral rotation of the operating element 50 relative to the first seat 10 rotates the second seat 30 on the operating element 50 in the opposite direction, so as to disengage from the plug 20.

In addition, the lateral rotation of the operating member 50 can be manually operated or driven by other parts.

Referring to fig. 2, 3 and 8, in the first embodiment, two stopping portions 14 are disposed on the base 11 of the first seat 10 to correspond to the two second seats 30, preferably, the first seat 10 further includes a side rotating member 15 pivotally connected to the base 11, and the stopping portions 14 are disposed on the side rotating member 15 and protrude from an inner wall surface of one side of the base 11 toward an inner wall surface of the other side of the base 11, but not limited thereto, the stopping portions 14 may also be directly protruded from the inner wall surface of one side of the base 11.

Referring to fig. 4, each second seat 30 is provided with a second seat actuation portion 31, and the second seat actuation portion 31 is preferably a protrusion with an arc inclined surface, and each plug 20 is provided with a plug actuation portion 21, and the plug actuation portion 21 is preferably a groove with an arc inclined surface.

Referring to fig. 6 and 7, when the plug 20 is inserted into the first seat 10, the magnetic attraction force rotates the second seat 30 to make the second seat actuation portion 31 cooperate with the plug actuation portion 21, so as to make the plug 20 enter the engagement state, specifically, the protrusion of the second seat actuation portion 31 is inserted into the groove of the plug actuation portion 21, so that the plug 20 cannot be disengaged from the first seat 10.

Referring to fig. 4, 7 and 8, after the second seat 30 is rotated by the magnetic attraction, the rotated second seat 30 is abutted by the blocking portion 14 of the first seat 10, so that the plug 20 is kept in the locked state. Preferably, one end of the rotated second seat 30, which faces away from the plug 20, is abutted by the stopping portion 14, so that the second seat 30 cannot rotate reversely, and therefore, the protrusion of the second seat actuating portion 31 cannot disengage from the groove of the plug actuating portion 21, and therefore, the plug 20 cannot disengage from the first seat 10, but the manner in which the stopping portion 14 keeps the plug 20 in the fastened state is not limited thereto.

When the operating member 50 is rotated laterally relative to the first seat 10, the second seat 30 of the operating member 50 is separated from the stopping portion 14 along with the lateral rotation of the operating member 50. Preferably, the lateral rotation of the operating member 50 is rotated away from the stopping portion 14, so that the laterally rotated second seat 30 avoids the stopping portion 14 and is no longer abutted by the stopping portion 14, and therefore, as the operating member 50 rotates laterally, the second seat 30 is returned to a state of being capable of rotating reversely and being disengaged from the plug 20. However, the way of disengaging the second seat 30 from the blocking portion 14 is not limited thereto.

Meanwhile, when the second seat 30 rotates along with the operation member 50, the second seat actuation portion 31 cooperates with the plug actuation portion 21 of the plug 20 to cause the second seat 30 to rotate reversely to disengage from the plug 20. Specifically, when the second seat 30 rotates along with the operation member 50, the protrusion of the second seat actuation portion 31 having the arc inclined surface moves along the groove of the arc inclined surface of the plug actuation portion 21, and the two arc inclined surfaces are shaped to push the second seat 30 away from the plug 20, so that the second seat 30 rotates in the opposite direction. However, the way of rotating the second seat 30 in the reverse direction to disengage the plug 20 is not limited thereto.

Referring to fig. 3, 9 and 10, during the lateral rotation of the operating element 50 relative to the first socket 10, the operating element 50 pushes the plug 20 to push the plug 20 out of the plug hole 13 of the first socket 10. In addition, as mentioned above, when the second seat 30 rotates along with the operating element 50, the second seat 30 rotates in a reverse direction, and during the process of the reverse rotation of the second seat 30, the second component 42 on the second seat 30 and the first component 41 on the plug 20 gradually incline, so that the angle of the magnetic force between the two gradually changes, and when the second seat 30 rotates in the reverse direction until the included angle between the second component 42 and the first component 41 is greater than a certain angle (preferably 7 degrees, but not limited thereto), the magnetic repulsion force between the second component 42 and the first component 41 is converted into a magnetic repulsion force to push out the plug 20. However, the manner in which the plug 20 is pushed out of the first seat 10 is not limited to the above two, and various changes may be made, for example, in an embodiment without the operating member 50, the second seat 30 may directly push against the plug 20 to push out the plug 20 (as shown in fig. 19).

In addition, referring to fig. 11 to fig. 16, the second embodiment of the present invention is realized through different methods: first, how to keep the plug 20 in the engaged state after the plug 20 is inserted into the first socket 10 and the second socket 30 is rotated by the magnetic attraction. Second, when the operating member 50 is laterally rotated with respect to the first housing 10, the second housing 30 is disengaged from the plug 20.

Referring to fig. 11 to 13, in the second embodiment, two rotation-stopping portions 16 are disposed on the first seat 10, which correspond to the two second seats 30, respectively, the rotation-stopping portions 16 are preferably elastic, and may be elastic components such as springs, or elastic through structures, in the embodiment, the rotation-stopping portions 16 are elastic pieces formed on the bottom surface of the base 11, and the free ends of the elastic pieces extend upward; usually, the second seat 30 is abutted to the elastic sheet downwards, and after the second seat 30 rotates due to the magnetic attraction, the second seat 30 is separated from the upper part of the elastic sheet and is instead abutted by the free end of the elastic sheet, so that the second seat 30 cannot rotate backwards, and the second seat 30 cannot be separated from the plug 20. When the unlocking is performed, the second seat 30 rotates along with the operating element 50, so that the second seat 30 avoids the elastic sheet of the rotation stop portion 16 and is no longer abutted by the rotation stop portion 16, and thus the second seat rotates reversely, and finally, when the operating element 50 rotates back to the original position relative to the first seat 10, the second seat 30 rotating along with the operating element 50 rotates back to the position above the elastic sheet of the rotation stop portion 16 again from the lateral direction.

Referring to fig. 11, 14 to 16, a first seat operating portion 17 is disposed on the first seat 10, and when the operating element 50 rotates relative to the first seat 10, the second seat 30 on the operating element 50 cooperates with the first seat operating portion 17 to separate the second seat 30 from the rotation stop portion 16 of the first seat 10. Preferably, the first seat actuation portion 17 may be a protrusion having a guiding inclined surface 171, and when the second seat 30 rotates along with the operation member 50, the second seat 30 abuts against the guiding inclined surface 171 and rotates along the guiding inclined surface 171 in a reverse direction, so as to disengage the second seat 30 from the plug 20. Specifically, the first seat actuation portion 17 may be formed on the base 11 of the first seat 10 (as shown in fig. 11), or may be formed on the inner side surface of the upper cover 12 (as shown in fig. 16), in this embodiment, each second seat 30 is simultaneously matched with the two first seat actuation portions 17 (the base 11 and the upper cover 12), so as to strengthen the detachment of the second seat 30 from the plug 20.

Referring to fig. 3 and 5, the control assembly 60 selectively prevents the operating member 50 from rotating relative to the first housing 10 and further prevents the second housing 30 from rotating in the opposite direction away from the plug 20 to prevent the plug 20 from entering the unlocked state.

The control unit 60 is preferably a lock, such as a key lock, a combination lock, an electronic lock (e.g., fingerprint recognition), etc., and the control unit 60 may be disposed in the first seat 10, or may be a separate lock, such as a padlock, etc., or even the control unit 60 may be a device other than a lock, so long as the operation member 50 is prevented from rotating relative to the first seat 10.

In the present embodiment, the control component 60 is a combination lock, and is disposed in the first seat 10, and one end of the control component is inserted into the operating element 50 to prevent the operating element 50 from rotating.

In addition, in the first and second embodiments, the number of the plug hole 13, the plug 20, the second seat 30, the first component 41 and the second component 42 of the first seat 10 is two, but not limited thereto, and may be changed to only one, so that the above-mentioned multiple functions can be performed.

Referring to fig. 17 to 19, the third embodiment of the present invention is modified to have no operation element 50, and when the unlocking is desired, the operation element directly rotates the second base 30, and preferably, the third embodiment further has a synchronization element 70, the synchronization element 70 can simultaneously drive the two second bases 30 to rotate, and preferably, the synchronization element 70 drives the two second bases 30 to synchronously rotate through a gear, so as to facilitate the operation.

When the third embodiment is used, after the plug 20 is inserted into the first seat 10, the second seat 30 rotates toward the plug 20 due to the magnetic attraction of the second component 42 and the first component 41, and then the plug 20 is engaged, so that the plug 20 cannot be separated from the first seat 10, and thus the plug 20 enters the engaging state.

When the locking is to be unlocked, the two second housings 30 are rotated by rotating the same moving member 70, and the second housings 30 are separated from the plug 20 after being rotated and simultaneously push against the plug 20 to push the plug 20 out of the plug hole 13 of the first housing 10.

The present invention assists the plug 20 to be inserted by playing a certain guiding role through the magnetic attraction between the first component 41 of the plug 20 and the second component 42 of the second seat 30; the magnetic attraction then assists in maintaining the invention in the latched condition when the plug 20 is inserted into position.

In addition, when unlocking, the two plugs 20 can be unlocked simultaneously or even the two plugs 20 can be withdrawn simultaneously by rotating the operating member 50 or the same moving member 70, so that the use is convenient.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
