[0034] The technical means adopted by the utility model to achieve the predetermined utility model purposes is further explained below with the preferred embodiments of the utility model and the accompanying drawings.
[0035] Please refer to the first embodiment of the magnetic fastening device of the utility model as shown in the drawings. Figures 1 to 4 The first embodiment of the magnetic fastening device of the utility model includes a first body 10, a second body 20, a clamping member 30, an operating member 40, a first element 50, a second element 60 and a lock 70.
[0036] As shown in the drawings, Figure 3 , Figures 10 to 12 The first body 10 and the second body 20 are detachably combined with each other. The clamping member 30 is movably or rotatably arranged on the first body 10; in the first embodiment, please refer to the drawings as shown, Figures 8 to 11 The clamping member 30 is rotatably arranged on the first body 10. The operating member 40 is movably or rotatably arranged on the first body 10, and as shown in the drawings, Figures 5 to 11 It is inclined to clamp the second body 20 and can be moved or rotated to disengage the second body 20 and push against the clamping member 30; in the first embodiment, the operating member 40 is movably arranged on the first body 10. Please refer to the drawings as shown, Figure 2 , Figure 3 and Figure 8 The first element 50 is arranged on the clamping member 30, and the second element 60 is arranged on the second body 20.
[0037] Please refer to the drawings as shown, Figures 3 to 6 The lock 70 is connected to the operating member 40 and has a locked state as shown in the drawings, Figure 4 and an unlocked state as shown in the drawings. Figures 5 to 7 When the first body 10 and the second body 20 are combined with each other, and the lock 70 is in the locked state, as shown in the drawings, Figure 4 The lock 70 prevents the operating member 40 from moving or rotating, at which time the operating member 40 keeps clamping the second body 20, thereby making the first body 10 and the second body 20 unable to be separated from each other.
[0038] When the first body 10 and the second body 20 are combined with each other, and the lock 70 is in the unlocked state, as shown in the drawings, Figures 5 to 7 , Figure 10and Figure 11 As shown, the lock 70 allows the operation member 40 to move or rotate, and the operation member 40 can move or rotate to disengage the second body 20 and push against the engaging member 30 to move or rotate, and as shown, the first element 50 on the engaging member 30 and the second element 60 on the second body 20 generate a magnetic repulsion force to make the first body 10 and the second body 20 tend to separate from each other. Figures 8 to 12 As shown, the first element 50 on the engaging member 30 and the second element 60 on the second body 20 generate a magnetic repulsion force to make the first body 10 and the second body 20 tend to separate from each other.
[0039] Specifically, in the first embodiment, the lock 70 is a password lock, but can also be a key lock or an electronic lock, and the lock 70 is arranged in the first body 10, but can also be arranged outside the first body 10 and connected thereto. When the lock 70 is in the unlocked state, that is, when the password lock is set to the correct password, as shown, the lock 70 allows the operation member 40 to move relative to the first body 10, and the operation member 40 can move to disengage the second body 20, and push against the engaging member 30 to rotate clockwise. Figures 5 to 7 , Figure 10 and Figure 11 As shown, the lock 70 allows the operation member 40 to move relative to the first body 10, and the operation member 40 can move to disengage the second body 20, and push against the engaging member 30 to rotate clockwise. Correspondingly, please refer to as shown, Figure 11 As shown, the first element 50 on the engaging member 30 and the second element 60 on the second body 20 generate a magnetic repulsion force to make the first body 10 and the second body 20 tend to separate from each other. Figure 8 and Figure 9 As shown, the first element 50 on the engaging member 30 and the second element 60 on the second body 20 generate a magnetic repulsion force to make the first body 10 and the second body 20 tend to separate from each other.
[0040] Therefore, after the engaging member 30 rotates, a magnetic repulsion force is generated between the first element 50 and the second element 60, and at this time the operation member 40 has disengaged the second body 20, so the magnetic repulsion force makes the first body 10 and the second body 20 tend to separate from each other. The present application can use a stronger magnetic repulsion force to make the first body 10 and the second body 20 move away from each other in opposite directions at the same time when the operation member 40 disengages the second body 20; but the present application can also use a weaker magnetic repulsion force to only make the first body 10 and the second body 20 tend to move away from each other in opposite directions, which still helps to separate the first body 10 and the second body 20 from each other to facilitate use. In the first embodiment, the first element 50 and the second element 60 are both magnets, but are not limited thereto, as long as a magnetic repulsion force can be generated.
[0041] When the lock 70 is in the locked state, that is, when the password lock is set to the wrong password, as shown, the operation member 40 is limited by the lock 70 and cannot move relative to the first body 10, at this time the operation member 40 cannot disengage the second body 20, and the operation member 40 remains engaged with the second body 20, thereby making the first body 10 and the second body 20 unable to separate from each other. Figure 4
[0042] Please refer to as shown, Figure 13 As shown in the second embodiment of the utility model, the engaging member 30 is movably arranged on the first body 10, and the operating member 40 is movably arranged on the first body 10, when the lock 70 is in the unlocking state, the lock 70 allows the operating member 40 to move towards the lock 70 (or allows the operating member 40 to rotate), the operating member 40 moves and separates from the second body 20 and pushes the engaging member 30 to move, and the magnetic repulsion force between the first element 50 on the moving engaging member 30 and the second element 60 on the second body 20 causes the first body 10 and the second body 20 to separate from each other. Specifically, for example, in the position shown in the figure, the magnetic attraction force between the first element 50 and the second element 60 can present magnetic attraction or weak magnetic repulsion and tend to separate from each other, and after the engaging member 30 is pushed and slides to the right, as the first element 50 moves to the right, the magnetic repulsion force between the first element 50 and the second element 60 gradually increases, so that the first body 10 and the second body 20 separate from each other. Figure 13
[0043] Please refer to the figure Figure 14 As shown in the third embodiment of the utility model, the engaging member 30 is rotatably arranged on the first body 10, and the operating member 40 is rotatably arranged on the first body 10, when the lock 70 is in the unlocking state, the lock 70 allows the operating member 40 to rotate around a pivot 401, and the operating member 40 can have a cam surface, so that after the operating member 40 rotates, a pushing member 402 is pushed and moves or rotates towards the engaging member 30, thereby pushing the engaging member 30 to rotate (or move) like the first embodiment of the utility model, and the magnetic repulsion force between the first element 50 and the second element 60 causes the first body 10 and the second body 20 to separate from each other. Wherein, after the operating member 40 rotates, the second body 20 can be released from the engagement, so that the first body 10 and the second body 20 separate from each other.
[0044] Through the above technical features, when the utility model is used, when the user wants to separate the first body and the second body, for example, the male-female buckle structure, only needs to unlock the lock 70 first, then moves or rotates the operating member 40, so that it gradually separates from the second body 20 and directly or indirectly moves or rotates the engaging member 30, drives the first element 50 on the engaging member 30 to change position or angle relative to the second element 60 on the second body 20, and then generates magnetic repulsion force, which helps the first body 10 and the second body 20 to separate from each other. In this way, the magnetic buckle device of the utility model is easy to separate, convenient to use, and the structure is simple, the cost is more reasonable, and the problems of the existing buckle device are effectively improved.
[0045] Further, please refer to the figure Figure 2 , Figure 8 , Figure 9 , Figure 13 and Figure 14 As shown, the second body 20 is provided with a positioning structure 21, and the engaging member 30 can abut against the positioning structure 21 after moving or rotating, and cannot continue to move or rotate. Specifically, during the process of combining the first body 10 and the second body 20, the engaging member 30 is in the opposite direction of the aforementioned unlocking process, that is, in the first embodiment and the third embodiment, the engaging member 30 can rotate counterclockwise; in the second embodiment, the engaging member 30 can move to the left, thereby returning to the original position. In this way, the next unlocking process can also be implemented as the unlocking process action as described above. And through the positioning structure 21 of the second body 20, the engaging member 30 can be ensured to be reset to the fixed position, thereby improving the reliability of the magnetic fastening device, and ensuring that the elements can smoothly act in the next unlocking process.
[0046] Further, in the embodiments of the present application, in addition to abutting to prevent the engaging member 30 from moving or rotating, the positioning structure 21 can also abut and engage the engaging member 30 at the same time, so that the first body 10 and the second body 20 cannot be separated from each other. In the present embodiment, the positioning structure 21 includes a hook 211 to engage the engaging member 30, and when the first body 10 and the second body 20 are combined, the hook 211 is buckled on the engaging member 30, so that the first body 10 and the second body 20 cannot be separated from each other. Please refer to the drawings as shown in Figure 8 and Figure 9 In the first embodiment of the present application, the engaging member 30 forms a U-shaped member, thereby accommodating the first element 50. When the first body 10 and the second body 20 are combined, the hook 211 of the positioning structure 21 is buckled on the opening of the U-shaped structure of the engaging member 30, so as to hook the engaging member 30, and the auxiliary operating member 40 prevents the first body 10 from moving in the direction away from the second body 20. When unlocking, since the engaging member 30 rotates clockwise, it can be separated from the hook 211, so as to subsequently separate the first body 10 and the second body 20.
[0047] In addition, as shown in Figure 13 In the second embodiment, the hook 211 is buckled on the engaging member 30 on the left side of the engaging member 30. In this way, when unlocking, the engaging member 30 moves to the right, thereby separating from the hook 211, so as to subsequently separate the first body 10 and the second body 20.
[0048] In addition, the structure (hook 211) of the second body 20 engaging the engaging member 30 can not be located on the positioning structure 21 but on other parts of the second body 20, and can also be other shapes without being limited to hooks. In addition, the structure (hook 211) of the second body 20 engaging the engaging member 30 can also be buckled on other parts or detailed structures of the engaging member 30, as long as it can produce the effect that the first body 10 and the second body 20 cannot be separated from each other.
[0049] Furthermore, in various embodiments of this utility model, through the aforementioned technical features, the engaging member 30 selectively engages the second body 20. When the first body 10 and the second body 20 are engaged together and the lock 70 is in the locked state, the engaging member 30 engages the second body 20, preventing the first body 10 and the second body 20 from separating. When the first body 10 and the second body 20 are engaged together and the lock 70 is in the unlocked state, after the operating member 40 moves or rotates to push against the engaging member 30, the engaging member 30 moves or rotates to disengage from the second body 20.
[0050] Preferably, when the first body 10 and the second body 20 are engaged, i.e., the operating member 40 is engaged with the second body 20, and the operating member 40 has not yet been moved or rotated, and therefore the engaging member 30 has not yet been moved or rotated, a magnetic attraction is generated between the first element 50 on the engaging member 30 and the second element 60 on the second body 20, causing the first body 10 and the second body 20 to tend to move closer to each other. For example, in the first embodiment, such as Figure 8 As shown, the bottom of the first element 50 is the N pole, and the top of the second element 60 is the S pole. Therefore, a magnetic attraction is generated between the first element 50 and the second element 60, causing the first body 10 and the second body 20 to tend to move closer to each other and become more difficult to separate, thereby improving the locking effect of the first body 10 and the second body 20. During the unlocking process, as the first element 50 moves or rotates with the engaging member 30, the N pole of the first element 50 flips to a position away from the second element 60, and the distance between the S poles of the first element 50 and the second element 60 shortens. This causes a magnetic repulsion between the first element 50 and the second element 60 after the engaging member 30 moves or rotates, allowing the first body 10 and the second body 20 to separate from each other.
[0051] Although in the above embodiment, when the S pole of the first element 50 rotates downward and approaches the S pole of the second element 60, that is, when the engaging member 30 rotates 180 degrees, a greater magnetic repulsion force can be generated between the first element 50 and the second element 60, in fact, even before the engaging member 30 has rotated to 180 degrees, as long as the side of the first element 50 with the same polarity is closer to the second element 60 than the side with the opposite polarity, a magnetic repulsion force can be generated between the first element 50 and the second element 60, thus helping the first body 10 and the second body 20 to separate.
[0052] The above magnetic pole configuration can be arranged in other ways. As long as the first element 50 and the second element 60 can generate magnetic attraction when the lock 70 is locked, and generate magnetic repulsion when the lock 70 is unlocked, or after the engaging member 30 moves or rotates.
[0053] More specifically, please refer to... Figures 8 to 11As shown, the engaging member 30 is combined with the first body 10 through the pivot portion 31, and the pivot portion 31 is formed at the middle position of the two ends of the engaging member 30. The operating member 40 pushes the engaging member 30 to the position away from the second element 60, so that the engaging member 30 can rotate relative to the first body 10. In this way, the operating member 40 does not push the pivot position of the engaging member 30 to cause the engaging member 30 to be unable to normally rotate, and does not hinder the first element 50 and the second element 60 to cause the potential motion or force interference problem.
[0054] Further, in the first embodiment of the utility model, two pushing structures are arranged between the operating member 40 and the engaging member 30, and the operating member 40 can push the engaging member 30 to rotate through the two pushing structures in opposite directions. As shown in Figure 2 、 Figure 3 、 Figure 8 and Figure 10 , the two pushing structures are respectively a first pushing structure 81 and a second pushing structure 82. Specifically, as shown in Figures 5 to 9 , the first pushing structure 81 comprises a slot 811 formed on the operating member 40 and a pushed wall 812 formed on the engaging member 30. When the operating member 40 and the engaging member 30 are installed to the first body 10, the engaging member 30 partially extends into the slot 811 on the operating member 40, so that the pushed wall 812 is located at the position corresponding to the inner side of the slot 811. When unlocking and separating the first body 10 and the second body 20, the operating member 40 moves to push the engaging member 30, and the inner side of the slot 811 approaches and abuts against the pushed wall 812 to push the engaging member 30 to rotate.
[0055] On the other hand, as shown in Figure 10 and Figure 11 , the second pushing structure 82 comprises a recess 821 formed on the operating member 40 and a protrusion 822 integrally formed on the pivot portion 31 of the engaging member 30. When the operating member 40 pushes the engaging member 30 to rotate, the protrusion 822 extends into the recess 821 on the operating member 40. In this way, when combining the first body 10 and the second body 20, the operating member 40 and the engaging member 30 act in the opposite direction, i.e. changes from the state shown in Figure 11 to the state shown in Figure 10 , and the operating member 40 needs to move reversely to engage the second body 20. During the movement of the operating member 40, the protrusion 822 on the engaging member 30 is pushed by the recess 821 on the operating member 40, so that the engaging member 30 can rotate in the direction opposite to the unlocking direction, i.e. counterclockwise in this embodiment.
[0056] Therefore, the two pushing structures arranged between the operating member 40 and the engaging member 30 can push the engaging member 30 to rotate through the corresponding pushing structures when the operating member 40 moves in the two opposite directions.
[0057] Further, the operation member 40 is provided with at least one engaging hook 41, when the first body 10 and the second body 20 are combined with each other, the engaging hook 41 buckles against the second body 20, so that the first body 10 and the second body 20 cannot be separated from each other. Please refer to the drawings as shown in Figure 3 , Figures 10 to 12 , in the first embodiment of the utility model, the number of the engaging hook 41 is two, and the second body 20 is provided with two engaging parts 22, when the first body 10 and the second body 20 are combined with each other, the engaging hook 41 and the engaging part 22 are engaged with each other, so as to prevent the first body 10 and the second body 20 from being separated from each other.
[0058] More specifically, the lock 70 can be a password lock, provided with at least one dial 71 and including at least one dial unlocking part 711; the operation member 40 includes at least one operation member unlocking part 42; when the lock 70 is in the unlocking state, the operation member unlocking part 42 corresponds to the dial unlocking part 711, allowing the operation member 40 to move or rotate towards the lock 70. Please refer to the drawings as shown in Figures 4 to 7 , in the first embodiment of the utility model, the lock 70 is provided with two dials 71, and each dial 71 is provided with a dial unlocking part 711, and the operation member 40 is provided with two operation member unlocking parts 42. Therefore, when the lock 70 is in the unlocking state, that is, the two dials 71 are turned to the correct password, as shown in Figures 5 to 7 , the operation member unlocking part 42 corresponds to the dial unlocking part 711, so that the operation member unlocking part 42 can be combined with the dial unlocking part 711, thereby allowing the operation member 40 to move towards the lock 70. On the contrary, when any dial 71 is in the wrong password, the dial unlocking part 711 corresponding to the wrong dial 71 does not correspond to the related operation member unlocking part 42, at this time, the wrong dial 71 abuts against the operation member 40, preventing the operation member 40 from moving, and further making the operation member 40 keep engaging with the second body 20. In the case of rotating movement of the operation member 40, similar design can also be realized based on the structure configuration of the second embodiment of the utility model, which will not be described here.
[0059] Preferably, in the first embodiment of the utility model, as shown in Figure 2 , Figure 5 and Figure 6 , at least one elastic member 43 is provided between the operation member 40 and the first body 10, so that the operation member 40 tends to engage with the second body 20. The elastic member 43 is better abutted in the positioning groove 101 of the first body 10, so as to prevent dislocation. In addition, in other embodiments, the operation member 40 and the first body 10 can also be configured by two repelling magnets, so that the operation member 40 tends to move or rotate in a certain direction, thereby realizing the technical feature of tending to engage with the second body 20.
[0060] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form, although the present application has been disclosed as above with preferred embodiments, however, is not intended to limit the present application, any person with ordinary knowledge in the art, without departing from the scope of the technical scheme of the present application, can make some changes or modifications to the above disclosed technical content for equivalent embodiments with equivalent changes, but as long as it does not deviate from the content of the technical scheme of the present application, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application, still belongs to the scope of the technical scheme of the present application.
