Description

Magnetic fastening device

Technical Field

The invention relates to a fastening device, in particular to a fastening device which can be used for various daily articles such as bags, backpacks and boxes and can detachably connect two components.

Background

The prior art bags are usually opened and closed by zippers, and some specific bags (such as luggage) are further provided with a buckling device which can be inserted with a zipper head and fix the zipper head, so that the zipper cannot be pulled to lock the bags.

However, the prior art fastener device has a disadvantage in that when the slider is inserted into the fastener device, the slider is required to be accurately aligned with the insertion hole of the fastener device, and then a certain amount of force is required to insert the slider into the insertion hole of the fastener device, which is inconvenient to use.

In addition, when the fastener device is to be opened, both hands are required to operate, specifically, one hand presses the fastener device to release the fastener head from the fastener, but the fastener head does not automatically separate from the fastener device, and the other hand pulls out the fastener head. Therefore, when the buckle is to be opened, both hands are needed to be used together, which causes great use limitation and great inconvenience in many cases.

Particularly, when the trunk is locked and unlocked, the user may not be in a state of conveniently moving both hands, and thus the fastening device which cannot be easily locked and unlocked is in need of improvement.

Disclosure of Invention

In view of the above-mentioned drawbacks and disadvantages of the prior art, the present invention provides a magnetic fastening device, which can be easily fastened.

To achieve the above-mentioned objective, the present invention provides a magnetic fastening device, comprising:

a housing;

a plug which can be inserted into the shell along a buckling direction to make the magnetic buckling device enter a buckling state;

a sliding seat movably arranged in the shell in a penetrating way;

the first magnetic component is arranged on the sliding seat;

the second magnetic component is arranged on the plug, and when the plug is inserted into the shell along the buckling direction, the magnetic force between the first magnetic component and the second magnetic component assists the magnetic buckling device to keep the buckling state;

a magnetic unlocking mechanism arranged on the sliding seat; in the process of pushing the sliding seat along an opening direction, the magnetic unlocking mechanism generates a magnetic repulsion force to the second magnetic assembly so as to withdraw the plug; the opening direction is different from the buckling direction;

the sliding seat comprises a seat body and a displacement piece, and the displacement piece is movably arranged in the seat body; the first magnetic component is arranged on the displacement piece; when the plug is inserted into the shell along the buckling direction to buckle the magnetic buckling device, the magnetic attraction force between the first magnetic component and the second magnetic component enables the displacement piece to move towards the direction opposite to the opening direction to buckle the plug, and then the magnetic buckling device is buckled.

The invention has the advantages that when the plug is close to the plug hole of the shell to be buckled, the magnetic attraction between the second magnetic component on the plug and the first magnetic component of the sliding seat in the shell 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 two magnetic components 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 of the two magnetic assemblies, thereby greatly improving the convenience in use.

When the magnetic unlocking mechanism is designed to enable the plug to automatically withdraw only by pressing the sliding seat with one hand, and the use of a user is facilitated.

Further, in the magnetic latching device, after the plug is withdrawn from the housing along with the movement of the slider, the plug is attached to the housing by the magnetic attraction between the first magnetic assembly and the second magnetic assembly. Therefore, the position of the plug can be fixed to avoid the loss of the plug due to falling off, and the plug can be prevented from being inserted back into the shell immediately after being withdrawn due to gravity or various reasons.

Further, in the magnetic latching device, the magnetic unlocking mechanism includes a third magnetic component disposed on the sliding seat, and a magnetic repulsion force is provided between the third magnetic component and the second magnetic component; in the process of pushing the sliding seat along the opening direction, the first magnetic assembly is gradually far away from the second magnetic assembly, the third magnetic assembly is gradually close to the second magnetic assembly, and the magnetic repulsion force between the third magnetic assembly and the second magnetic assembly exits from the plug; when the plug is withdrawn from the shell along with the movement of the sliding seat, the plug is obliquely pushed out of the shell along with the magnetic attraction between the first magnetic assembly and the second magnetic assembly moved by the sliding seat, and the plug is attached to the shell along with the magnetic attraction between the first magnetic assembly and the second magnetic assembly.

Further, in the magnetic latching device, the magnetic unlocking mechanism includes a flip member pivotally connected to the slider and connected to the housing, and the first magnetic member is disposed on the flip member; the sliding seat is pushed along the opening direction to enable the overturning part to overturn relative to the sliding seat, and a magnetic repulsion force is generated between the first magnetic assembly and the second magnetic assembly along with the change of the angle of the overturning part so as to withdraw the plug; after the plug is withdrawn from the shell, the sliding seat is continuously pushed along the opening direction to enable the overturning piece to overturn relative to the sliding seat, and the first magnetic assembly changing the angle along with the overturning piece and the second magnetic assembly generate a magnetic attraction force to enable the plug to be attached to the shell.

Further, in the magnetic latching device, the flip member is pivotally disposed on the sliding seat at one side, and the flip member can selectively move along with the sliding seat to be attached to the bottom surface of the sliding seat.

Further, in the magnetic latching device, when the sliding base is not pushed by an external force, the flip-flop is attached to the bottom surface of the sliding base, and a magnetic attraction force is generated between the first magnetic assembly and the second magnetic assembly to assist the magnetic latching device to maintain the latching state.

Further, in the magnetic fastening device, the turning angle of the turning member is greater than or equal to 90 degrees in a process from when the sliding base is not pushed by an external force to when the sliding base is pushed to the innermost end of the moving stroke along the opening direction by the external force.

Further, in the magnetic latching device, two guide portions are disposed on two opposite sides of an inner wall surface of the housing, two opposite sides of the flip member respectively abut against the two guide portions, and when the slider is pushed in the opening direction, the flip member moving along with the slider is pushed by the two guide portions to be guided and flipped relative to the slider.

Further, in the magnetic latching device, at least one rack is disposed on an inner wall surface of the housing, at least one tooth portion is disposed on a pivot shaft of the flip member and the slide base, the at least one tooth portion engages with the at least one rack, and when the slide base is pushed in the opening direction, the at least one tooth portion moves and rotates on the at least one rack to flip the flip member relative to the slide base.

Further, in the process that the magnetic latching device pushes the sliding seat along the opening direction, the magnetic repulsion force generated by the magnetic unlocking mechanism to the second magnetic assembly enables one side of the plug opposite to the opening direction to tilt, so that the relative angle between the first magnetic assembly and the second magnetic assembly is changed, and the plug is withdrawn from the shell.

Detailed Description

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

Referring to fig. 1 to 3, the magnetic fastening device of the present invention includes a housing 10, a sliding base 20, a plug 30, a first magnetic assembly 40, a second magnetic assembly 50, and a magnetic unlocking mechanism. The housing 10 and the plug 30 are respectively used to connect two components to be fastened with each other, for example, the housing 10 may be a locking device on a suitcase, and the plug 30 may be a zipper head of a zipper, but not limited thereto, and the present invention may also be applied to various fields other than suitcases.

Referring to fig. 1 and 2, or referring to fig. 8 and 11, the housing 10 has an inner space, a plug hole 11 and a slide hole 12, in this embodiment, the plug hole 11 is formed on a top surface of the housing 10, and the slide hole 12 is formed on a side surface of the housing 10. In addition, in the embodiment, the housing 10 is composed of a base 13 and an upper cover 14, but not limited thereto.

Referring to fig. 4 and 5, or referring to fig. 11 and 12, the plug 30 can be inserted into the housing 10 from the plug hole 11 along a fastening direction D1 to enable the present invention to enter a fastening state (as shown in fig. 5), the fastening state refers to a state where the plug 30 cannot be separated from the housing 10, and the slider 20 can movably penetrate through the housing 10 from the slider hole 12.

When the plug 30 is close to the plug hole 11 of the housing 10, the magnetic attraction between the second magnetic component 50 of the plug 30 and the first magnetic component 40 of the slider 20 in the housing 10 will play a certain guiding role, so that the plug 30 is closer to the plug hole 11 of the housing 10 and the plug 30 is inclined to be inserted, thereby assisting the insertion of the plug 30; then, when the plug 30 is inserted to the position, the magnetic attraction between the two

magnetic members

40 and 50 will also assist in keeping the present invention in the locked state. The two

magnetic elements

40, 50 may be either magnets or metals, or both magnets, so long as they generate a magnetic attraction force therebetween. In the present embodiment, the first magnetic assembly 40 is disposed in the sliding base 20, and the first magnetic assembly 40 and the second magnetic assembly 50 are still spaced apart from each other even though the plug 30 is inserted into the sliding base.

Referring to fig. 5 to 7, or referring to fig. 12 to 14, the magnetic unlocking mechanism is disposed on the sliding base 20, and in a process of pushing the sliding base 20 along an opening direction D2, the magnetic unlocking mechanism generates a magnetic repulsion force to the second magnetic assembly 50 to eject the plug 30, wherein the opening direction D2 is different from the latching direction D1, and preferably, the opening direction D2 is perpendicular to the latching direction D1, but not limited thereto.

The magnetic unlocking mechanism can be used to eject the plug 30 mainly by other mechanisms (such as a tilting abutting portion 222 or an inclined abutting surface 221 described later), and the magnetic unlocking mechanism can further enhance the function of ejecting the plug 30 to assist in ejecting the plug 30, but can also be used to eject the plug 30 by the magnetic unlocking mechanism alone without being matched with other mechanisms.

In addition, referring to fig. 7, in a preferred embodiment, after the plug 30 is withdrawn from the housing 10 along with the movement of the sliding seat 20, the plug 30 is still attached to the housing 10 by the magnetic attraction between the first magnetic component 40 and the second magnetic component 50, so that the position of the plug 30 can be fixed to prevent the plug 30 from being lost due to falling off, and the plug 30 can be prevented from being inserted back into the housing 10 due to gravity or various reasons after being withdrawn. However, the second magnetic assembly 50 may not be attached to the housing 10 as described above according to various requirements or according to the specific structure of the magnetic unlocking mechanism.

Referring to fig. 3 and 4, the first embodiment of the magnetic unlocking mechanism of the present invention includes a third magnetic element 60. The third magnetic assembly 60 is disposed on the sliding base 20, and a magnetic repulsion force is provided between the third magnetic assembly 60 and the second magnetic assembly 50 on the plug 30; in other words, the first magnetic assembly 40 on the slide 20 attracts the second magnetic assembly 50 on the plug 30, but the third magnetic assembly 60 on the slide 20 repels the second magnetic assembly 50 on the plug 30; therefore, in the first embodiment, the third magnetic assembly 60 on the sliding base 20 and the second magnetic assembly 50 on the plug 30 are both magnets, but the first magnetic assembly 40 on the sliding base 20 can be a magnet or a metal.

Referring to fig. 5 to 7, in the process of pushing the sliding base 20 along the opening direction D2, the magnetic attraction forces of the first magnetic assembly 40 on the sliding base 20 and the second magnetic assembly 50 on the plug 30 tend to drive the plug 30 to move along the opening direction D2, but the plug 30 is limited by the wall surface of the plug hole 11 and cannot move along with the plug, so the first magnetic assembly 40 on the sliding base 20 is gradually far away from the second magnetic assembly 50 on the plug 30, and the magnetic attraction force is gradually weakened; at the same time, the third magnetic member 60 of the slider 20 is gradually moved closer to the second magnetic member 50, so that the magnetic repulsive force is gradually increased, and the gradually increased magnetic repulsive force is used to withdraw the plug 30. Specifically, as the slider 20 moves, the second magnetic element 50 on the plug 30 receives a magnetic attraction force toward the first magnetic element 40 and receives a magnetic repulsion force toward the third magnetic element 60, so that the plug 30 gradually tilts toward one side (the side 31 opposite to the opening direction D2) of the third magnetic element 60, and further changes the relative angle between the second magnetic element 50 on the plug 30 and the other two

magnetic elements

40, 60, so that the magnetic forces of the second magnetic element 50 and the other two

magnetic elements

40, 60 become unbalanced, and the tilted plug 30 is in an unstable state, and finally, when the distance between the third magnetic element 60 and the second magnetic element 50 is reduced to a certain extent and the magnetic repulsion force is increased to a certain extent, the magnetic repulsion force causes the plug 30 to pass through the wall surface of the plug hole 11 and obliquely exit the housing 10, and the plug 30 does not immediately move and then eject out again after a certain time, so that the plug 30 can have the effect.

Referring to fig. 7, when the plug 30 is withdrawn from the housing 10 along with the movement of the slider 20, the plug 30 is attached to the housing 10 by the magnetic attraction between the first magnetic assembly 40 and the second magnetic assembly 50 of the plug 30 along with the movement of the slider 20.

Referring to fig. 9 to 11, a second embodiment of the magnetic unlocking mechanism of the present invention includes a turning member 70. The flip member 70 is pivoted to the slide 20 and connected to the housing 10, and the first magnetic assembly 40 is disposed on the flip member 70. Pushing the slide 20 in the opening direction D2 causes the flip member 70 to flip relative to the slide 20, and the first magnetic assembly 40, which changes the angle with the flip member 70, generates a magnetic repulsion force with the second magnetic assembly 50 to eject the plug 30.

In a preferred embodiment, the tilting member 70 is pivoted to the bottom surface of the sliding seat 20 by one side, and the tilting member 70 can selectively abut upwards against the bottom surface of the sliding seat 20 along with the movement of the sliding seat 20, but not limited thereto. Preferably, the rotation angle of the turning member 70 is greater than or equal to 90 degrees from the time when the sliding base 20 is not pushed by external force to the time when the sliding base 20 is pushed to the innermost end of the moving stroke in the opening direction D2 by external force, and in the embodiment, the rotation angle is 90 degrees, but not limited thereto.

In addition, in the present embodiment, when the sliding base 20 is not pushed by an external force, the flip-flop 70 abuts up to the bottom surface of the sliding base 20, and when the flip-flop 70 abuts against the bottom surface of the sliding base 20, the first magnetic component 40 on the flip-flop 70 and the second magnetic component 50 on the plug 30 are in an attracted state to assist the magnetic latching device to maintain the latching state. However, it is not limited to this, and the same function can be achieved by that after the sliding base 20 is pushed by an external force, the flip-flop 70 is abutted to the bottom surface of the sliding base 20, and when the sliding base 20 is not pushed by the external force, the flip-flop 70 is not abutted to the bottom surface of the sliding base 20, but the current angle of the flip-flop 70 still makes the first magnetic assembly 40 and the second magnetic assembly 50 on the plug 30 in an attractive state.

In addition, as to how the tilting member 70 is tilted relative to the slide 20 by the movement of the slide 20, at least the following two mechanisms can be achieved:

referring to fig. 9 and 11, in the first embodiment of the tilting member 70, two opposite sides of the inner wall surface of the housing 10 are respectively provided with a guiding portion 15, two opposite sides of the tilting member 70 respectively abut against the two guiding portions 15, and when the sliding seat 20 is pushed along the opening direction D2, the tilting member 70 moving along with the sliding seat 20 is pushed by the two guiding portions 15 to tilt relative to the sliding seat 20. Preferably, each guiding portion 15 is a long groove, and two opposite sides of the turning member 70 respectively protrude an abutting rod 71, and the two abutting rods 71 respectively penetrate through the long grooves of the two guiding portions 15, so as to achieve the effect of turning the turning member 70 guided by the guiding portions 15.

In addition, referring to fig. 11 to fig. 14, in the present embodiment, the guiding track of the guiding portion 15 includes a turning section 151 and a fastening section 152 connected to each other, the turning section 151 and the fastening section 152 both extend linearly, the fastening section 152 is parallel to the opening direction D2, and the turning section 151 is not parallel to the opening direction D2, so that when the abutting rod 71 of the turning member 70 moves on the turning section 151, the turning member 70 turns relative to the sliding base 20 with the pivot of the turning member 70 and the sliding base 20 as the axle center.

Preferably, as shown in fig. 11, when the slide 20 is not pushed by external force and the plug 30 is not inserted into the housing 10, the abutting rod 71 of the turning piece 70 is located at one end of the turning section 151, and the turning piece 70 abuts against the bottom surface of the slide 20 at this time. As shown in fig. 14, when the abutting rod 71 of the flip 70 moves to the other end of the flip segment 151, the flip 70 rotates 90 degrees, and the first magnetic assembly 40 on the flip 70 and the second magnetic assembly 50 on the plug 30 generate a magnetic repulsion force to eject the plug 30.

In addition, as shown in fig. 15, in another embodiment, the guiding track of the guiding portion 15 may also be continued, so that after the plug 30 exits the housing 10, the slider 20 is further pushed in the opening direction D2 to turn the turning member 70 relative to the slider 20, and a magnetic attraction force is generated between the first magnetic assembly 40 and the second magnetic assembly 50 as the turning member 70 changes the angle, so that the plug 30 abuts against the housing 10. Specifically, the guiding track of the guiding portion 15 further includes a turning section 153, and the turning section 153 is connected to the turning section 151 to form a V shape together with the turning section 151, so that the turning member 70 can be turned back to abut against the bottom surface of the sliding seat 20, and the plug 30 can abut against the housing 10.

The guide track and the rotation angle of the guide part 15 are not limited to this, and can be adjusted according to the requirement.

In addition, the function of the fastening section 152 will be described later.

Referring to fig. 16, in the second embodiment of the tilting member 70, at least one rack 16 is disposed on the inner wall surface of the housing 10, and preferably, one rack 16 is disposed on each of two opposite sides of the inner wall surface of the housing 10, and at least one tooth portion 72 is disposed on the pivot shaft of the tilting member 70 and the slide carriage 20, and preferably, one tooth portion 72 is disposed on each of two opposite ends of the pivot shaft, and the two tooth portions 72 respectively engage with the two racks 16, so that when the slide carriage 20 is pushed in the opening direction D2, the tooth portions 72 move and rotate on the racks 16 to tilt the tilting member 70 relative to the slide carriage 20. Each toothed portion 72 may be in particular a gear or even just a tooth, just as long as it can engage the toothed rack 16.

Referring to fig. 12 to 14, when the sliding base 20 moves along the opening direction D2 relative to the housing 10, in addition to the magnetic unlocking mechanism for ejecting the plug 30, the plug 30 can also be ejected by other mechanisms, and in this embodiment, in the process of pushing the sliding base 20 along the opening direction D2, the movement of the sliding base 20 generates a pushing force in a direction opposite to the fastening direction D1 to resist the magnetic attraction between the first magnetic assembly 40 and the second magnetic assembly 50, so that the side 31 opposite to the opening direction D2 on the plug 30 tilts to change the relative angle between the first magnetic assembly 40 and the second magnetic assembly 50 (as shown in fig. 13), and at this time, the magnetic force between the first magnetic assembly 40 and the second magnetic assembly 50 becomes unbalanced, thereby making the tilted plug 30 in an unstable state; as the sliding base 20 is continuously pushed, the first magnetic assembly 40 moving along with the sliding base 20 continuously pulls the plug 30 in an unstable state through the magnetic attraction force, and generates a moment on the inclined plug 30; thus, the slider 20 is pushed to the end, and the plug 30 is withdrawn from the housing 10 by the combined action of the moment caused by the magnetic attraction and the pushing force generated by the pushing, so that the pushing force generated by the pushing helps to withdraw the plug 30 from the housing 10.

More specifically, regarding the specific way of generating a pushing force in the direction opposite to the buckling direction D1 by the movement of the sliding seat 20, in the present embodiment, the sliding seat 20 has an abutting surface 221, and a tilting pushing portion 222 protrudes from the abutting surface 221, in the present embodiment, the tilting pushing portion 222 is a bump having an inclined plane, but the shape is not limited thereto; during the process of pushing the slider 20 along the opening direction D2, the tilting pushing portion 222 pushes the side 31 of the plug 30 opposite to the opening direction D2 in a direction opposite to the fastening direction D1, thereby generating the pushing force and tilting the side 31 of the plug 30 to change the relative angle between the first magnetic element 40 and the second magnetic element 50. However, the method of generating the thrust force is not limited to the above, and various changes may be made.

In addition, referring to fig. 11, in the present embodiment, a normal L1 of the abutting surface 221 on the sliding seat 20 is not perpendicular to the opening direction D2; therefore, when the plug 30 is inserted into the housing 10 along the fastening direction D1 to fasten the present invention, one end of the plug 30 located in the housing 10 abuts against the abutting surface 221 of the sliding seat 20, and when the sliding seat 20 is pushed toward the opening direction D2, the plug 30 gradually rises along the inclined abutting surface 221, so as to facilitate withdrawing the plug 30, but not limited thereto, please refer to fig. 4, it is also possible to make the abutting surface 221 be a horizontal plane as required, that is, the normal L1 of the abutting surface 221 is perpendicular to the opening direction D2.

In addition, as shown in fig. 12, when the plug 30 is inserted into the housing 10 along the engaging direction D1 to engage the present invention, the first magnetic element 40 and the second magnetic element 50 are parallel to each other, and the central line L2 of the first magnetic element 40 is not perpendicular to the opening direction D2, in other words, the first magnetic element 40 and the second magnetic element 50 are both inclined toward the oblique pushing direction of the plug 30, which is also helpful for allowing the magnetic attraction force to drive the plug 30 to obliquely exit from the housing 10. However, without limitation, as shown in fig. 5, the central line L2 of the first magnetic element 40 may also be perpendicular to the opening direction D2.

In addition, in the embodiment, please refer to fig. 2 and 8, at least one sliding seat elastic component 81 is further provided, which is disposed between the housing 10 and the sliding seat 20, and is used for pushing the sliding seat 20 in a direction opposite to the opening direction D2, so that the sliding seat 20 is pushed back by the sliding seat elastic component 81 after the plug 30 is withdrawn and the user stops applying force to the sliding seat 20. In the present embodiment, the number of the carriage elastic assemblies 81 is two, and the two are located on both sides of the carriage 20. But not limited thereto, the slider elastic member 81 may be omitted to allow the user to manually push the slider 20 back to the original position.

In addition, in the embodiment, as shown in fig. 3 to 5 or fig. 10 to 12, the sliding base 20 further includes a base 21 and a displacement member 22; the seat body 21 protrudes from the slide seat hole 12 of the housing 10, the seat body 21 is a portion of the slide seat 20 for being pushed by a user, and the slide seat elastic component 81 pushes the seat body 21; the displacement member 22 is movably disposed in the seat body 21 along the opening direction D2, the displacement member 22 is a portion of the sliding seat 20 corresponding to the plug 30, the first magnetic assembly 40 is disposed on the displacement member 22, and the abutting surface 221 and the tilting abutting portion 222 are both formed on the displacement member 22; therefore, when the plug 30 is inserted into the housing 10, the magnetic attraction between the first magnetic assembly 40 and the second magnetic assembly 50 moves the engaging portion 223 of the displacement element 22 in the direction opposite to the opening direction D2 to engage with the engaging groove 32 of the plug 30, so that the present invention is engaged (enters the engaging state). Therefore, before the plug 30 is inserted into the plug hole 11 of the housing 10, the buckling portion 223 of the displacement member 22 does not appear in the insertion path of the plug 30, so that the insertion of the plug 30 is not hindered, and the user is prevented from taking effort to insert the plug 30. In addition, referring to fig. 11 and 12, if the second embodiment of the magnetic unlocking mechanism (the flip-flop 70) is used, when the plug 30 is inserted into the housing 10 and the engaging portion 223 of the displacement member 22 moves to engage with the engaging groove 32 of the plug 30, the abutting rod 71 of the flip-flop 70 will move from one end of the flip-flop segment 151 to the engaging segment 152, so that the engaging segment 152 is prevented from interfering with the engaging segment 152.

However, in another embodiment, the slide 20 may not be divided into the seat 21 and the displacement member 22, and the slide 20 is formed integrally, in this embodiment, before the plug 30 is inserted into the plug hole 11 of the housing 10, the engaging portion 223 of the displacement member 22 is present in the insertion path of the plug 30, and when the user inserts the plug 30, the user needs to push the engaging portion 223 away along with the whole slide 20, or the user manually pushes the slide 20, and after the plug 30 is inserted to a fixed position, the slide elastic component 81 and the magnetic attraction forces of the first magnetic component 40 and the second magnetic component 50 push the slide 20 together to engage the engaging portion 223 with the plug 30. This is applicable to the situation where it is necessary to avoid easy locking, and still has the function of guiding the insertion of the plug 30 by the magnetic attraction of the first and second

magnetic elements

40 and 50.

In addition, referring to fig. 4 or fig. 11, in an embodiment that the sliding base 20 includes the base 21 and the displacement member 22, the sliding base may further include a displacement member elastic component 82, which is disposed between the base 21 and the displacement member 22, and pushes the displacement member 22 toward the opening direction D2 relative to the base 21, so that after the plug 30 is withdrawn, the displacement member elastic component 82 automatically pushes the displacement member 22 back to the original position, but not limited thereto, and the displacement member elastic component 82 may be absent, so that the user manually pushes the displacement member 22 back to the original position.

In summary, as shown in fig. 4 and fig. 5, or as shown in fig. 11 and fig. 12, by respectively providing the first magnetic assembly 40 and the second magnetic assembly 50 on the sliding base 20 and the plug 30, when the plug 30 is close to the plug hole 11 of the housing 10, the magnetic attraction between the first magnetic assembly 40 and the second magnetic assembly 50 plays a certain role in guiding, so that the plug 30 is closer to the plug hole 11 and the plug 30 tends to be inserted, thereby assisting the insertion of the plug 30.

Then, when the plug 30 is inserted to the position, the magnetic attraction between the first magnetic assembly 40 and the second magnetic assembly 50 drives the displacement member 22 to move, so that the engaging portion 223 is engaged with the plug 30, and the invention is engaged. Therefore, the user can easily buckle the lock without applying force intentionally.

Therefore, the present invention not only facilitates the insertion of the guiding plug 30, but also effectively reduces the force applied by the user by the magnetic attraction of the first magnetic assembly 40 and the second magnetic assembly 50, thereby greatly improving the convenience in use.

In addition, when the buckling state is to be released, please refer to fig. 5 to 7, or please refer to fig. 12 to 14, in the process of pushing the sliding seat 20 along the opening direction D2, the pushing action of the sliding seat 20 may cause the magnetic unlocking mechanism (the third magnetic component 60 or the first magnetic component 40 turned by the turning piece 70) to generate a magnetic repulsion force to the second magnetic component to withdraw the plug 30, and further, the plug 30 may be obliquely withdrawn and then attached to the housing 10 to prevent the plug 30 from falling off or inadvertently returning to the housing 10 to buckle again.

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.
