Abstract

The invention relates to a magnetic buckling device, which comprises a shell, a main plug, a main sliding seat, two main components and a control component, wherein the main plug is arranged on the shell; the main plug can be inserted into the shell and buckled; the main sliding seat and the shell can move or rotate relatively to enable the main plug to enter an unlocking state; the two main components are respectively arranged on the main sliding seat and the main plug. When the main plug is close to the main plug hole of the shell, a magnetic attraction force is generated between the two main components to guide the main plug to be close to the main plug hole of the shell and to lead the main plug to be inserted; when the main plug is inserted, the magnetic attraction between the two main components can also assist the main plug to keep a buckled state, so that the use convenience is improved. The control assembly selectively prevents the main sliding seat and the shell from moving or rotating relatively so as to prevent unlocking, and when the main plug needs to be withdrawn, the control assembly drives the main sliding seat and the shell to move or rotate relatively.

Description

Magnetic fastening device

Technical Field

The invention relates to a buckling device, in particular to a buckling device which can be used for various daily necessities such as bags, backpacks and boxes, can detachably connect two components and is controlled through a lockset.

Background

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

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

In addition, some cases (such as luggage) have two zipper sliders on the zipper, and the two zipper sliders can be inserted into the fastening device at the same time, so that the case can not be opened at all. However, the two sliders are often close to each other when being inserted into the fastener device, so that the two sliders are convenient to insert and lock, but are close to each other when being unlocked, so that the two sliders are too close to each other to grab any one of the two sliders, thereby causing inconvenience in use.

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 housing;

a main plug which can be inserted into the shell along a main buckling direction so as to enable the main plug to enter a buckling state;

the main sliding seat and the shell can move or rotate relatively to enable the main plug to enter an unlocking state;

a first main assembly provided on the main carriage;

the second main component is arranged on the main plug, and when the main plug is inserted into the shell along the main buckling direction, a magnetic attraction force is generated between the first main component and the second main component to assist the main plug to keep the buckling state;

a control component which selectively prevents the main sliding seat and the shell from relatively moving or rotating so as to prevent the main plug from entering the unlocking state.

When the auxiliary plug is used, when the main plug is close to the main plug hole of the shell, the magnetic attraction between the second main component on the main plug and the first main component of the main sliding seat in the shell can play a certain guiding role, so that the main plug is closer to the main plug hole of the shell and tends to be inserted, and the insertion of the main plug is assisted; then, after the main plug is inserted into the positioning part, the magnetic attraction between the two main 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 does not need to apply force, and the main plug can be positioned and buckled through the magnetic attraction; therefore, the invention not only facilitates the insertion of the main plug through the magnetic attraction of the two main components, but also can effectively reduce the force application of a user, thereby greatly improving the convenience in use.

In addition, when the main plug is to be withdrawn, the control component does not prevent the relative movement or rotation between the main sliding seat and the shell, and the receiver can relatively move or rotate the main sliding seat and the shell to enable the main plug to enter the unlocking state, or directly relatively move or rotate the control component and the shell to enable the main plug to enter the unlocking state.

In other words, the present invention may have only one set of plug (main plug 20) and related components, or may have two sets of plug (main plug 20, sub-plug 60) and related components, which all can exert the object of the present invention.

Referring to fig. 1 and 2, the housing 10 and the main plug 20 are respectively used to connect two components to be fastened to each other, the housing 10 and the sub-plug 60 are also respectively used to connect two components to be fastened to each other, for example, the housing 10 can be a locking device on a suitcase, the main plug 20 and the sub-plug 60 can be zipper sliders of a zipper, and the control component 50 is preferably a lock, such as a combination lock, a lock requiring a key, or a lock having two unlocking methods at the same time, so as to be a device for controlling whether the suitcase can be opened, but not limited thereto, the present invention can also be applied to various fields other than suitcases, and the control component 50 can also be a device other than a lock, and only needs to control the main plug 20 and the sub-plug 60 to exit.

The housing 10 has an inner space, a main plug hole 11 and a sub plug hole 12, and in the present embodiment, the main plug hole 11 and the sub plug hole 12 are formed on the top surface of the housing 10. In addition, in the embodiment, the control assembly 50 is disposed in the casing 10, and therefore, a hole for exposing the control assembly 50 is further disposed on the casing 10, but not limited thereto, the control assembly 50 may also be disposed outside the casing 10 and then inserted into the casing 10 to drive the assembly in the casing 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. 7 to 10, the main plug 20 can be inserted into the housing 10 from the main plug hole 11 along a main engaging direction D1 to make the main plug 20 enter an engaging state (as shown in fig. 8), the engaging state refers to a state where the main plug 20 cannot be separated from the housing 10, the main slider 30 is movably disposed in the housing 10, and the main slider 30 can be moved relative to the housing 10 along a main opening direction D2 to make the main plug 20 enter an unlocking state, preferably the main plug 20 is withdrawn when the unlocking state is performed (as shown in fig. 10), but the unlocking state is not limited to withdrawing the main plug 20, as long as the main plug 20 can be separated from the housing 10; the main opening direction D2 is different from the main fastening direction D1, and preferably, the main opening direction D2 is perpendicular to the main fastening direction D1, but not limited thereto.

The aforementioned auxiliary plug 60 can be inserted into the housing 10 from the auxiliary plug hole 12 along an auxiliary engaging direction D3 to make the auxiliary plug 60 enter an engaging state (as shown in fig. 8), the engaging state is a state in which the auxiliary plug 60 cannot be separated from the housing 10, the auxiliary slider 70 is movably disposed in the housing 10, and the auxiliary slider 70 can be moved relative to the housing 10 along an auxiliary opening direction D4 to make the auxiliary plug 60 enter an unlocking state, preferably to withdraw the auxiliary plug 60 (as shown in fig. 10) when in the unlocking state, but the unlocking state is not limited to withdrawing the auxiliary plug 60 as long as the auxiliary plug 60 can be separated from the housing 10; the secondary opening direction D4 is different from the secondary fastening direction D3, and the secondary opening direction D4 is preferably perpendicular to the secondary fastening direction D3, but not limited thereto.

In the present embodiment, the primary engagement direction D1 of the primary plug 20 and the secondary engagement direction D3 of the secondary plug 60 are the same, that is, the primary plug 20 and the secondary plug 60 are both inserted from the top surface of the housing 10, but not limited thereto, the primary plug 20 and the secondary plug 60 may be inserted into the housing 10 from different directions. In the present embodiment, the main opening direction D2 and the auxiliary opening direction D4 are opposite, but not limited thereto, the main opening direction D2 and the auxiliary opening direction D4 may be designed to be the same.

In the foregoing embodiment, the main slider and the sub slider are both inserted into the housing and pushed to enter the unlocking state, but not limited thereto, the main slider and the sub slider may not be inserted into the housing, for example, the main slider and the sub slider are disposed on a side surface of the housing. In addition, the main slide seat and the auxiliary slide seat can be moved to the unlocking state by pushing the shell relative to the main slide seat and the auxiliary slide seat.

In the foregoing embodiment, the main slider and the sub slider are relatively moved with respect to the housing, but not limited thereto, and may be rotated with respect to the housing, or the housing may be rotated with respect to the main slider and the sub slider.

Referring to fig. 3, 4, 7 and 8, the first main component 41 is disposed on the main sliding seat 30, and the second main component 42 is disposed on the main plug 20, when the main plug 20 is close to the main plug hole 11 of the housing 10, a magnetic attraction force is generated between the second main component 42 on the main plug 20 and the first main component 41 of the main sliding seat 30 in the housing 10 to play a certain guiding role, so that the main plug 20 is closer to the main plug hole 11 of the housing 10 and the main plug 20 is inclined to be inserted, thereby assisting the insertion of the main plug 20; then, when the main plug 20 is inserted to the position, the magnetic attraction between the two

main components

41 and 42 will also assist to keep the main plug 20 in the engaged state. The two

main components

41, 42 may be either a magnet or a metal, or both may be magnets, so long as magnetic attraction is generated therebetween. In the present embodiment, the first main member 41 is provided in the main slider 30, and the first main member 41 and the second main member 42 are still spaced from each other even if the main plug 20 is inserted to be positioned, but not limited thereto.

Referring to fig. 3, 4, 7 and 8, the first sub-assembly 81 is disposed on the sub-slider 70, and the second sub-assembly 82 is disposed on the sub-plug 60, when the sub-plug 60 is close to the sub-plug hole 12 of the housing 10, a magnetic attraction force is generated between the second sub-assembly 82 on the sub-plug 60 and the first sub-assembly 81 of the sub-slider 70 in the housing 10 to play a certain guiding role, so that the sub-plug 60 is closer to the sub-plug hole 12 of the housing 10 and the sub-plug 60 is inclined to be inserted, thereby assisting the insertion of the sub-plug 60; then, when the sub-plug 60 is inserted to the position, the magnetic attraction between the two

sub-assemblies

81 and 82 also helps to keep the sub-plug 60 in the locked state. The two

subassemblies

81, 82 may be either magnets or metal, or both magnets, so long as they generate magnetic attraction between them. In the present embodiment, the first sub-assembly 81 is disposed in the sub-slider 70, and the first sub-assembly 81 and the second sub-assembly 82 are still spaced apart from each other even when the sub-plug 60 is inserted into the sub-slider 70.

In addition, the first main component 41, the second main component 42, the first sub-component 81 and the second sub-component 82 may be independent components or may be directly integrated on the components, for example, the first main component 41 may be integrated with the main sliding seat 30, so that the main sliding seat 30 itself is a magnet or a metal, or the second sub-component 82 may be integrated with the sub-plug 60, so that the sub-plug 60 itself is a magnet or a metal, and so on.

Referring to fig. 4 to 6, the movement of the main slider 30 to withdraw the main plug 20 drives the sub slider 70 to move relative to the housing 10 to withdraw the sub plug 60. When the secondary opening direction D4 is opposite to the primary opening direction D2, in a preferred embodiment, the primary slide 30 has a primary rack 34 protruding toward the secondary slide 70, the secondary slide 70 has a secondary rack 74 protruding toward the primary slide 30, and a gear 15 is disposed between the primary rack 34 and the secondary rack 74 to engage with the primary rack 34 and the secondary rack 74 simultaneously, because the primary rack 34 and the secondary rack 74 are located on opposite sides of the gear 15, respectively, so that the rotation of the gear 15 reversely drives the primary rack 34 and the secondary rack 74 to move in opposite directions, but the mechanism of the primary slide 30 driving the secondary slide 70 is not limited thereto, and may be in other forms. In addition, in the embodiment in which the secondary opening direction D4 is the same as the primary opening direction D2, it is sufficient to directly interconnect the primary and

secondary carriages

30, 70 or even to form them integrally.

The aforementioned control assembly 50 selectively prevents the main slider 30 and the housing 10 from moving or rotating relatively, so as to prevent the main plug 20 from entering the unlocked state, and when the main slider 30 and the housing 10 are prevented from moving or rotating relatively, the secondary slider 70 is also limited by the main slider 30, so that the secondary slider 70 and the housing 10 cannot move or rotate relatively, so as to prevent the secondary plug 60 from entering the unlocked state, so that the control assembly 50 indirectly controls the state of the secondary plug 60. However, the control component 50 may also directly contact the secondary slide carriage 70, and directly and selectively prevent the secondary slide carriage 70 and the housing 10 from relatively moving or rotating to prevent the secondary plug 60 from entering the unlocking state, at this time, the primary plug 20 and the primary slide carriage 30, and the secondary plug 60 and the secondary slide carriage 70 are two independent sets of structures, and the control component 50 controls the two sets of structures simultaneously. In the present embodiment, the control assembly 50 selectively prevents the main carriage 30 from moving relative to the housing 10 in the main opening direction D2 to withdraw the main plug 20, and when the main carriage 30 is restricted by the control assembly 50 from moving to withdraw the main plug 20, the sub-carriage 70 is also restricted by the main carriage 30 from moving relative to the housing 10 to withdraw the sub-plug 60. However, without being limited thereto, the control assembly 50 may also directly contact the sub-carriage 70, and directly and selectively prevent the sub-carriage 70 from moving relative to the housing 10 in the sub-opening direction D4 to withdraw the sub-plug 60.

Furthermore, in the preferred embodiment, the control unit 50 is connected to the main carriage 30 and controls the movement of the main carriage 30 in the main opening direction D2 and in the opposite direction of the main opening direction D2, in other words, the control unit 50 can move the main carriage 30 directly in both directions. However, without limitation, the control unit 50 may only block the main carriage 30 from moving in the main opening direction D2, and the movement of the main carriage 30 is otherwise controlled.

Referring to fig. 4-7, in the embodiment where the control assembly 50 can directly move the main sliding seat 30 in both directions, preferably, the control assembly 50 includes a lock core 51 and a linking member 52. The linkage 52 connects the main slider 30 and drives the main slider 30 to move along the main opening direction D2 and along the opposite direction of the main opening direction D2. The lock core 51 may be a combination lock, a lock requiring a key, or a lock having two unlocking methods. The lock core 51 has a rotatable output portion 511, the rotatable output portion 511 is connected to the linking member 52, and the lock core 51 drives the linking member 52 to move along the main opening direction D2 and along the opposite direction of the main opening direction D2 by rotating the rotatable output portion 511. Preferably, the rotation output portion 511 drives the linking member 52 to move linearly in two directions through a gear and a rack, but not limited thereto, the lock core 51 may also output in a linear movement manner instead of a rotation manner, so as to drive the linking member 52.

Referring to fig. 8 to 10, when the main plug 20 and the sub plug 60 are inserted into the housing 10 and enter the locked state, the lock core 51 is unlocked and then the rotation output portion 511 is rotated, so that the main slider 30 and the sub slider 70 are simultaneously driven to move to simultaneously withdraw from the main plug 20 and the sub plug 60.

Next, a specific implementation manner of the main slider 30 moving in the main opening direction D2 to eject the main plug 20 is described, and a specific implementation manner of the sub slider 70 moving in the sub opening direction D4 to eject the sub plug 60 is substantially the same, so that the detailed description is not repeated, and the main slider 30 and the main plug 20 are mainly described below.

Referring to fig. 8 to 10, in the present embodiment, during the process of pushing the main sliding seat 30 along the main opening direction D2, the movement of the main sliding seat 30 generates a pushing force in a direction opposite to the main fastening direction D1 to resist the magnetic attraction between the two main components 41 and 42, so that the side 21 of the main plug 20 opposite to the main opening direction D2 is tilted to change the relative angle between the first main component 41 and the second main component 42 (as shown in fig. 9), and at this time, the magnetic force between the two main components 41 and 42 becomes unbalanced, so that the tilted main plug 20 is in an unstable state; as the main slider 30 is continuously pushed, the first main component 41 moving along with the main slider 30 continuously pulls the unstable main plug 20 through the magnetic attraction force, and generates a moment to the inclined main plug 20; therefore, the main slider 30 is pushed to the end, and the main plug 20 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 main plug 20 from the housing 10. However, the manner of withdrawing the main plug 20 through the movement of the main slider 30 is not limited to the above, and various modifications are possible.

More specifically, regarding the specific manner of generating a pushing force in the direction opposite to the main fastening direction D1 through the movement of the main slider 30, in the present embodiment, the main slider 30 has a main toppling-pushing portion 311, and in the present embodiment, the main toppling-pushing portion 311 is a bump having an inclined plane, but the shape is not limited thereto; in the process of pushing the main slider 30 in the main opening direction D2, the main tilting and pushing portion 311 pushes the side 21 of the main plug 20 opposite to the main opening direction D2 in the direction opposite to the main engaging direction D1, so as to generate the pushing force and tilt the side 21 of the main plug 20 to change the relative angle between the two

main components

41 and 42. However, the method of generating the thrust force is not limited to the above, and various changes may be made.

Further, in the present embodiment, when the main plug 20 is withdrawn from the housing 10 along with the movement of the main slider 30, a magnetic attraction force between the first main component 41 and the second main component 42 on the main plug 20 along with the movement of the main slider 30 generates a component force in the lateral direction, so that the main plug 20 is withdrawn from the housing 10 in an oblique direction (as shown in fig. 10), and after the main plug 20 is pushed out of the housing 10, it is still attracted toward the first main component 41 and abuts against the housing 10 (as shown in fig. 10) by the magnetic attraction force between the two

main components

41, 42. By obliquely withdrawing the main plug 20 from the housing 10, the probability of the main plug 20 being actually withdrawn from the housing 10 is increased, and the main plug 20 is prevented from being inserted into the housing 10 immediately after being withdrawn due to various reasons. However, it is not limited thereto, and in other embodiments, the main plug 20 may be withdrawn from the housing 10 in a direction opposite to the primary engaging direction D1 instead of being withdrawn obliquely.

In the present embodiment, referring to fig. 2, 9 and 10, two thrust portions 16 are preferably formed on the walls of the main plug hole 11 and the sub plug hole 12 to block the main plug 20 and the sub plug 60 respectively, on the housing 10. In the process of pushing the main slider 30 in the main opening direction D2, the thrust portion 16 abuts against the main plug 20 to prevent the main plug 20 from moving along with the main slider 30 in the main opening direction D2, so that the main plug 20 does not move along with the main slider 30 at once due to the magnetic attraction of the moving first main component 41, but the main plug 20 obliquely exits the housing 10 beyond the thrust portion 16 due to the magnetic attraction after the side 21 tilts up due to the pushing force (e.g., the main tilting pushing portion 311), and the main plug 20 does not move along with the main slider immediately and exits after a certain time of accumulation, so that the main plug 20 can have the ejecting effect. In addition, in the embodiment in which the main plug 20 is to be simply withdrawn from the housing 10 in the direction opposite to the main engaging direction D1, the thrust portion 16 can maintain the withdrawal direction of the main plug 20 without deflection.

In addition, as shown in fig. 8, when the main plug 20 is inserted into the housing 10 along the main engaging direction D1 to make the main plug 20, the first main component 41 and the second main component 42 are parallel to each other, and the center line of the first main component 41 is perpendicular to the main opening direction D2, but not limited thereto, in other embodiments, the center lines of the first main component 41 and the second main component 42 may also be not perpendicular to the main opening direction D2, in other words, both the

main components

41 and 42 are inclined toward the oblique pushing direction of the main plug 20, which also helps to make the magnetic attraction force drive the main plug 20 to obliquely exit the housing 10.

In addition, in the present embodiment, referring to fig. 3, fig. 4 and fig. 7, the main sliding seat 30 further includes a main seat 31 and a main displacement member 32. The main seat 31 is a portion of the main slide 30 blocked or connected by the control component 50, the main rack 34 is disposed on the main seat 31, and the main toppling pushing portion 311 is formed on the main seat 31. The main displacement member 32 is movably disposed in the main housing 31 along a main opening direction D2, the main displacement member 32 is a portion of the main slider 30 corresponding to the main plug 20, and the first main assembly 41 is disposed on the main displacement member 32. Referring to fig. 7 and 8, when the main plug 20 is inserted into the housing 10, the magnetic attraction between the first main component 41 and the second main component 42 moves the main engaging portion 321 of the main displacement member 32 in the direction opposite to the main opening direction D2 to engage with the main engaging groove 22 of the main plug 20, so that the main plug 20 enters the engaging state. Therefore, before the main plug 20 is inserted into the main plug hole 11 of the housing 10, the main engaging portion 321 of the main displacement member 32 does not appear in the insertion path of the main plug 20, so that the insertion of the main plug 20 is not hindered, and the user is prevented from taking effort to insert the main plug 20.

However, in another embodiment, the main sliding seat 30 may not be divided into the main seat 31 and the main displacement member 32, and at this time, the main sliding seat 30 is formed as an integral body, in this embodiment, before the main plug 20 is inserted into the main plug hole 11 of the housing 10, the main engaging portion 321 of the main displacement member 32 appears in the insertion path of the main plug 20, and when the user inserts the main plug 20, the user needs to push the main engaging portion 321 together with the whole main sliding seat 30, or the user manually pushes the main sliding seat 30, and after the main plug 20 is inserted to a fixed position, the magnetic attraction forces of the two

main components

41, 42 push the main sliding seat 30 together to make the main engaging portion 321 engage with the main plug 20. Although not as convenient in use as the previous embodiment, it can be applied to the situation where it is necessary to avoid easy locking, and still has the function of guiding the insertion of the main plug 20 through the magnetic attraction of the two

main components

41, 42.

In addition, referring to fig. 3, fig. 4 and fig. 7, in the embodiment that the main sliding seat 30 includes the main seat 31 and the main displacement element 32, a main displacement element elastic element 33 may be further included, which is disposed between the main seat 31 and the main displacement element 32, and pushes the main displacement element 32 toward the main opening direction D2 relative to the main seat 31, so that after the main plug 20 is withdrawn, the main displacement element elastic element 33 will automatically push the main displacement element 32 back to the original position, but not limited thereto, or the main displacement element elastic element 33 may be omitted so that the user can manually push the main displacement element 32 back to the original position.

In addition, referring to fig. 3 and 11, regarding the main engaging portion 321 of the main displacement member 32 and the main engaging groove 22 of the main plug 20, in the embodiment, the main displacement member 32 has two main engaging portions 321, the main plug 20 has two main engaging grooves 22 respectively located at two opposite sides, when the main plug 20 moves along the main engaging direction D1, the two main engaging portions 321 are respectively inserted into the two main engaging grooves 22, and are respectively engaged from two sides, so as to achieve the purpose of stably engaging the main plug 20.

The following describes portions of the sub-slider 70 and the sub-plug 60:

referring to fig. 3, 4 and 7, the sub-slider 70 includes a sub-base 71, a sub-shifter 72 and a sub-shifter resilient assembly 73. The sub-displacement member 72 is movably disposed in the sub-seat body 71. The sub seat 71 is a portion of the sub slider 70 connected to the main seat 31, and the sub rack 74 is provided on the sub seat 71. The sub-displacement member elastic assembly 73 is disposed between the sub-seat 71 and the sub-displacement member 72, and pushes the sub-displacement member 72 in the sub-opening direction D4 with respect to the sub-seat 71. The first sub-assembly 81 is provided on the sub-displacer 72. When the sub-plug 60 is inserted into the housing 10 in the sub-engaging direction D3, the magnetic attraction between the first sub-assembly 81 and the second sub-assembly 82 moves the sub-displacement member 72 in the direction opposite to the sub-opening direction D4 to engage with the sub-plug 60, thereby bringing the sub-plug 60 into the engaged state. The detailed structures of the sub-seat 71 and the sub-displacement member 72 are substantially the same as those of the main seat 31 and the main displacement member 32, and therefore, the detailed description thereof is omitted.

As shown in fig. 8 to 10, in the process of pushing the sub sliding seat 70 along the sub opening direction D4, a pushing force is generated in the opposite direction of the sub engaging direction D3 to resist the magnetic attraction between the first sub-assembly 81 and the second sub-assembly 82, so that the side of the sub plug 60 opposite to the sub opening direction D4 tilts to change the relative angle between the first sub-assembly 81 and the second sub-assembly 82, thereby withdrawing the sub plug 60 from the housing 10. The sub carriage 70 has a sub tilting abutting portion 711. During the process of pushing the sub slider 70 along the sub opening direction D4, the sub toppling pushing portion 711 pushes the side of the sub plug 60 opposite to the sub opening direction D4 in the opposite direction of the sub latching direction D3, so as to generate the pushing force in the opposite direction of the sub latching direction D3. When the sub-plug 60 is withdrawn from the housing 10 in accordance with the movement of the sub-slider 70, the magnetic attraction between the first sub-assembly 81 and the second sub-assembly 82 moving in accordance with the sub-slider 70 pushes the sub-plug 60 obliquely out of the housing 10, and the magnetic attraction between the first sub-assembly 81 and the second sub-assembly 82 brings the sub-plug 60 into contact with the housing 10. Preferably, the secondary opening direction D4 is opposite to the primary opening direction D2, and the primary plug 20 and the secondary plug 60 are obliquely pushed out of the housing 10 in a direction away from each other, so that the primary plug 20 and the secondary plug 60 are prevented from being collided together, and the primary plug 20 and the secondary plug 60 are both attached to the housing 10 by magnetic attraction without running, thereby facilitating the user to grasp one of the primary plug 20 and the secondary plug 60. The details of the sub-slider 70 and the sub-plug 60 are the same as those of the main slider 30 and the main plug 20, and thus, the description thereof will not be repeated.

In summary, referring to fig. 7 and 8, the components are respectively disposed on the sliders (the main slider 30, the sub slider 70) and the plugs (the main plug 20, the sub plug 60), so that when the plugs are close to the plug holes of the housing 10, the magnetic attraction between the two corresponding components will play a certain guiding role, and the plugs are closer to the plug holes and tend to be inserted, thereby assisting the insertion of the plugs.

Then, when the plug is inserted to the position, the magnetic attraction between the two corresponding components will drive the displacement components (the primary displacement component 32 and the secondary displacement component 72) to move and block the plug, so that the plug enters the buckling state. Therefore, the user can easily buckle without applying force intentionally.

Therefore, the invention not only facilitates the insertion of the guide plug through the magnetic attraction of the assembly, but also can effectively reduce the force application of a user, thereby greatly improving the convenience in use.

In addition, when unlocking, the control unit 50 will push the two

sliders

30, 70 simultaneously, and then withdraw the two

plugs

20, 60 simultaneously, and the two

plugs

20, 60 will be pushed out of the housing 10 obliquely in the direction away from each other and abut against the housing 10 away from each other, so that the user can grasp one of the two

plugs

20, 60 conveniently, and the present invention is therefore convenient to use.

In addition, referring to fig. 12 to 16, in the second embodiment of the present invention, the control assembly 50 can directly push the main sliding seat 30 back and forth along the main opening direction D2, specifically, the control assembly 50 includes a knob 53 and a linking member 54, the knob 53 is pivotally disposed on the housing 10 and can push the linking member 54 back and forth along the main opening direction D2 as pivoting relative to the housing 10, the linking member 54 can be disposed in the housing 10 in a manner of moving back and forth along the main opening direction D2, and one end of the linking member is connected to and fixed to the main sliding seat 30, so that a user can toggle the knob 53 to rotate to move the position of the main sliding seat 30 (as shown in fig. 15 and 16). In addition, in the second embodiment, the main slider 30 and the main plug 20 are farther from the control component 50 than the secondary plug 60 and the secondary slider 70, but not limited thereto, the main slider 30 and the main plug 20 may also be closer to the control component 50.

In addition, referring to fig. 14, 17 and 18, in the second embodiment, the movement of the main slider 30 to withdraw the main plug 20 also drives the sub-slider 70 to withdraw the sub-plug 60 relative to the housing 10, specifically, a rotating wheel 17 is disposed between the main slider 30 and the sub-slider 70, the rotating wheel 17 links the main slider 30 and the sub-slider 70, when the main slider 30 moves along the main opening direction D2 or the opposite direction thereof, the movement of the main slider 30 drives the rotating wheel 17 to rotate, and the rotation of the rotating wheel 17 drives the sub-slider 70 to move along the opposite direction of the main slider 30. In a preferred embodiment, the main slide 30 is formed with a main elongated slot 35, the main elongated slot 35 extends in a direction preferably perpendicular to the main opening direction D2, the secondary slide 70 is formed with a secondary elongated slot 75, the secondary elongated slot 75 extends in a direction preferably perpendicular to the secondary opening direction D4, and two guide posts 171 protrude from the rotary wheel 17 and are respectively inserted into the main elongated slot 35 of the main slide 30 and the secondary elongated slot 75 of the secondary slide 70, so as to achieve the purpose of converting the movement into rotation and the rotation into movement.

Referring to fig. 15 and 16, in the second embodiment, when the plug is in the engaged state, the main slider 30 (along the main opening direction D2) and the sub slider 70 (along the sub opening direction D4) are forcibly pushed by the toggle knob 53, and the main tilting abutting portion 311 of the main slider 30 and the sub tilting abutting portion 711 of the sub slider 70 respectively eject the main plug 20 and the sub plug 60 out of the housing 10 (an instant throwing phenomenon occurs).

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
