Description

Magnetic fastener

TECHNICAL FIELD

[0001] The present application relates to a safety buckle, in particular to a magnetic fastener.

BACKGROUND

[0002] A safety buckle generally comprises a female buckle and a male buckle, wherein the male buckle is provided with a lock tongue and the female buckle is provided with a lock hole, and the lock tongue is inserted into the lock hole to enable the male buckle and the female buckle to be connected together in a locked manner. By operating the unlocking, the male buckle and the female buckle can also be separated from each other.

[0003] Generally, the locking structure on the female buckle is generally composed of a lock hole and a position-changeable locking part. When the locking part protrudes in the lock hole, it can play a locking role to lock the lock tongue in the lock hole, so as to enable the locked connection of the male buckle and the female buckle. When the locking part exits the lock hole, the lock tongue can freely enter and exit the lock hole and exit from the lock hole, so as to enable the separation of the male buckle and the female buckle.

[0004] When the male buckle and the female buckle are inserted, the lock tongue generally presses the locking part; the locking part is moved away by the pressing of the lock tongue to enable the lock tongue to continue to advance; and when the lock tongue is completely inserted into the lock hole, the locking part needs to automatically return to the original state to lock the lock tongue, so as to realize the locked connection of the male buckle and the female buckle. Therefore, during the process of inserting the lock tongue into the lock hole, the locking part is passively moved away and needs to be automatically returned to the original position for locking. Therefore, in the existing safety buckle, an elastic component needs to be arranged in the female buckle, the elastic force of the elastic component is used to provide the opportunity for the movement of the locking part, so that the locking part can be pushed by the lock tongue, and the elastic force of the elastic component is used to realize the automatic locking of the locking part. For example, ZL201910147794.7.

DETAILED DESCRIPTION

[0036] The following examples are further explanation and supplement to the present application, and do not constitute any limitation to the present application.

[0037] As shown in Figs. 1-4, the magnetic fastener of the present application comprises a male fastener 10 and a female fastener 20, the main point of which is that a third magnetic member 23 is arranged in the female fastener 20, and the third magnetic member 23 interacts with the second magnetic member 12 in the lock tongue 11 to actuate the latching member 22 to achieve locking.

[0038] As shown in Figs. 1-4, the male fastener 10 and the female fastener 20 can be connected together and can be separated from each other. The male fastener 10 is provided with a lock tongue 11, and the female fastener 20 is provided with a corresponding lock hole 24, and the lock tongue 11 can be inserted into the lock hole 24 in the locking direction to connect the male fastener 10 and the female fastener 20 together. When the unlocking operation is performed, the lock tongue 11 can be withdrawn from the lock hole 24 to separate the male fastener 10 and the female fastener 20 from each other.

[0039] As shown in Figs. 1-4, the female fastener 20 is provided with a first magnetic member 21, and the male fastener 10 is provided with a second magnetic member 12. The first magnetic member 21 and the second magnetic member 12 attract each other in the locking direction of the male fastener 10 and the female fastener 20. When the male fastener 10 and the female fastener 20 are close to a certain distance, the first magnetic member 21 and the second magnetic member 12 attract each other to enable the lock tongue 11 to be quickly inserted into the lock hole 24.

[0040] As shown in Figs. 1-4, the position of the first magnetic member 21 corresponds to the position of the lock hole 24. The position of the second magnetic member 12 corresponds to the position of the lock tongue 11. Generally, the second magnetic member 12 is arranged in the lock tongue 11.

[0041] The shapes of the first magnetic member 21 and the second magnetic member 12 are not limited, and they are preferably the same shape. In this embodiment, the first magnetic member 21 and the second magnetic member 12 are circular magnets.

[0042] As shown in Figs. 1-4, the lock tongue 11 is latched, and the latching member 22 is arranged in the female fastener 20. The latching member 22 is movably arranged in the female fastener 20 and can move in the female fastener 20.

[0043] As shown in Figs. 1-4, the latching member 22 is provided with a latching portion 221. When the latching portion 221 extends within the range of the lock hole 24, it has the ability to lock the lock tongue 11, at this time, the latching portion 221 can latch the lock tongue 11 to connect the male fastener 10 and the female fastener 20 together. When the latching portion 221 moves to a certain extent in the direction of withdrawing from the lock hole 24, for example, completely out of the range of the lock hole 24, the latching portion 221 loses the ability to lock the lock tongue 11, at this time, the male fastener 10 and the female fastener 20 can be separated from each other.

[0044] As shown in Figs. 1-4, a third magnetic member 23 is provided on the latch member 22 to actuate the latch member 22 without the use of elastic members. The third magnetic member 23 is fixed relative to the latch member 22.

[0045] During a first stage of the insertion of the lock tongue 11 into the lock hole 24, the magnetic force between the third magnetic member 23 and the second magnetic member 12 can cause the latch member 22 to move in a first direction perpendicular to the locking direction to a first position or to remain in the first position.

[0046] During a second stage of the insertion of the lock tongue 11 into the lock hole 24, the magnetic force between the third magnetic member 23 and the second magnetic member 12 can cause the latch member 22 to move in a second direction perpendicular to the locking direction from the first position to a second position to engage the lock tongue 11.

[0047] During the first and second stages, the magnetic force between the third magnetic member 23 and the second magnetic member 12 changes in nature due to the change in distance. The magnetic force of the third magnetic member 23 and the second magnetic member 12 themselves does not change, but the position of the lock tongue 11 relative to the lock hole 24 changes during the insertion of the lock tongue 11 into the lock hole 24, and thus the position and distance of the second magnetic member 12 relative to the third magnetic member 23 changes, resulting in a change in the nature of the magnetic force between the third magnetic member 23 and the second magnetic member 12.

[0048] In the first stage, the magnetic force between the third magnetic member 23 and the second magnetic member 12 is repulsive, and thus in the first stage, the second magnetic member 12 repels the third magnetic member 23 to keep the latch member 22 in the first position or to move the latch member 22 in the first direction to the first position, keeping the latch member 22 away from the lock tongue 11. In the first position, the latch member 221 is not within the range of the lock hole 24, and the latch member 221 cannot engage the lock tongue 11 or hinder the insertion of the lock tongue 11 into the lock hole 24.

[0049] In the second stage, the magnetic force between the third magnetic member 23 and the second magnetic member 12 is attractive, and thus in the second stage, the second magnetic member 12 attracts the third magnetic member 23 to actuate the latch member 22, causing the latch member 22 to move in the second direction from the first position to the second position. In the second position, the latch member 221 is within the range of the lock hole 24, and the latch member 221 engages the lock tongue 11, causing the male buckle 10 and the female buckle 20 to engage together.

[0050] The first direction and the second direction are two directions parallel to each other and opposite to each other. The first direction is a direction in which the locking portion 221 is away from the locking hole 24. The second direction is a direction in which the locking portion 221 enters the locking hole 24.

[0051] During the process of inserting the locking tongue 11 into the locking hole 24, the locking member 22 can be actuated by the magnetic force between the third magnetic member 23 and the second magnetic member 12, so that the locking member 22 is engaged with the locking tongue 11, thereby achieving the engagement connection between the male buckle 10 and the female buckle 20. During the process, the locking tongue 11 can easily enter the locking hole 24 without being pressed by the locking portion 221, and the locking member 22 can move without being deformed by the elastic member.

[0052] Further, the locking member 22 is a rigid structure, and the third magnetic member 23 is fixed on the locking member 22, so that the locking member 22 can move under the magnetic force. The locking portion 221 moves to the locked state only by the magnetic force between the third magnetic member 23 and the second magnetic member 12, so that the structure of the locking member 22 can be greatly simplified, and the size of the female buckle 20 can be reduced, thereby facilitating the miniaturization of the structure.

[0053] In the default state, i.e., when the male buckle 10 and the female buckle 20 are in a separated state and are not subjected to external force, the position of the locking portion 221 can be set to be outside the range of the locking hole 24, or can be set to be not outside the range of the locking hole 24. In the default state of the conventional safety buckle provided with an elastic member, the locking portion 221 must be set to be outside the range of the locking hole 24. When the locking member 22 is actuated by the magnetic force, the default position of the locking portion 221 can be flexibly set.

[0054] To more specifically describe the structure of the present application, different embodiments are described as follows:

[0055] Embodiment 1

[0056] As shown in FIGS. 1-2, the male buckle 10 is provided with the locking tongue 11 and the second magnetic member 12.

[0057] As shown in FIGS. 1-2, the locking tongue 11 is in a protruding shape, and the end thereof is in a circular truncated cone shape and is provided with a first conical surface. The first conical surface facilitates the locking tongue 11 to enter the locking hole 24. To achieve locking, a groove portion 111 is provided on the locking tongue 11, which is used to cooperate with the locking portion 221 to achieve locking connection. The groove portion 111 is located slightly away from the end surface of the locking tongue 11. The groove portion 111 can be set to be annular, or can be set to be a shape matching the shape and size of the locking portion 221. When the locking tongue 11 enters the locking hole 24, the locking portion 221 can be stopped in the groove portion 111, so that the male buckle 10 and the female buckle 20 are locked and connected together.

[0058] As shown in FIG. 1 and FIG. 2, the second magnetic member 12 is arranged at a position corresponding to the position of the lock tongue 11. In the present embodiment, the second magnetic member 12 is arranged in the lock tongue 11.

[0059] As shown in FIG. 1 and FIG. 2, the female buckle 20 includes a housing 25, a locking member 22, a first magnetic member 21, and a third magnetic member 23.

[0060] As shown in FIG. 1 and FIG. 2, the housing 25 is used to arrange the locking member 22 and the first magnetic member 21, and the shape and structure thereof can be arranged as required. Generally, for the convenience of processing and assembly, the housing 25 usually includes a first housing 251 and a second housing 252 which are connected together. When the first housing 251 and the second housing 252 are connected together, an accommodating cavity is formed in the interior thereof, which can be used to arrange the locking member 22 and the first magnetic member 21. In addition, for the convenience of arranging the first magnetic member 21, a magnet holder 253 can be arranged in the interior of the housing 25 as required.

[0061] In order to facilitate the insertion of the lock tongue 11 of the male buckle 10 into the female buckle 20, the lock hole 24 is arranged on the housing 25. The shape of the lock hole 24 can be arranged as required, and in the present embodiment, the lock hole 24 is a circular hole.

[0062] As shown in FIG. 1 and FIG. 2, the position of the first magnetic member 21 in the female buckle 20 should be opposite to the position of the lock hole 24, so that the first magnetic member 21 can be conveniently attracted to the second magnetic member 12 in the lock tongue 11.

[0063] The locking member 22 is movably arranged in the housing 25. As shown in FIG. 1 and FIG. 2, the locking member 22 includes a locking portion 221, an unlocking portion 222, and a magnet mounting portion 223 which are fixedly connected or integrally formed. Further, the locking member 22 can further include an enclosing portion 224.

[0064] The locking portion 221 is used to engage with the lock tongue 11 to enable the male buckle 10 and the female buckle 20 to be engaged together. The locking portion 221 can be inserted into the groove portion 111 of the lock tongue 11 in a second direction, so that the lock tongue 11 and the locking member 22 are engaged together.

[0065] The unlocking portion 222 is partially exposed to the housing 25 of the female buckle 20, and can be used to perform an unlocking operation. For example, a pressing operation or a pulling operation can be performed.

[0066] The magnet mounting portion 223 is provided with a magnet mounting groove 2231 which is used to arrange the third magnetic member 23. The size and shape of the magnet mounting groove 2231 can be arranged as required, and in the present embodiment, the magnet mounting groove 2231 is a rectangular groove, and the third magnetic member 23 which is rectangular in shape is arranged in the magnet mounting groove 2231.

[0067] Further, the enclosing portion 224 is annular, corresponding to the position of the lock hole 24, and larger than the circumferential dimension of the lock hole 24.

[0068] The latching portion 221 and the unlocking portion 222 are respectively arranged on the enclosing portion 224 and spaced opposite to each other. In the embodiment, the latching portion 221 and the unlocking portion 222 are located on the same diameter of the enclosing portion 224 and spaced opposite to each other. The magnet mounting portion 223 is connected with the latching portion 221, and the magnet mounting portion 223 is located on the side of the latching portion 221 opposite to the unlocking portion 222.

[0069] In other words, the latching portion 221 and the magnet mounting portion 223 are located on one side of the enclosing portion 224, and the unlocking portion 222 is located on the other side of the enclosing portion 224.

[0070] The default position of the latching portion 221 is affected by the magnetic force between the third magnetic member 23 and the first magnetic member 21, which can be at the first position, can be at the second position, or can be at any position between the first position and the second position.

[0071] When the lock tongue 11 is inserted in the locking direction, in the first stage, the third magnetic member 23 repels the second magnetic member 12, so that the latching portion 221 remains in the first position or moves to the first position in the first direction.

[0072] When the default state of the latching portion 221 is at the first position, in the first stage, the magnetic repulsion force between the third magnetic member 23 and the second magnetic member 12 cannot actuate the latching member 22, and the latching member 22 still remains in the first position.

[0073] When the default state of the latching portion 221 is not at the first position, in the first stage, the magnetic repulsion force between the third magnetic member 23 and the second magnetic member 12 will actuate the latching member 22 to move the latching member 22 in the first direction to the first position, so as to move to the first position.

[0074] When the lock tongue 11 continues to advance, the magnetic force between the third magnetic member 23 and the second magnetic member 12 changes in nature to enter the second stage, at this time, the third magnetic member 23 and the second magnetic member 12 attract each other, so as to actuate the latching member 22 to move from the first position to the second position in the second direction, so as to be engaged with the lock tongue 11 to realize the engagement connection of the male buckle 10 and the female buckle 20.

[0075] When the female buckle 20 and the male buckle 10 are locked together, and unlocking is needed, the unlocking portion 222 is pressed, the latching member 22 moves in the first direction as a whole, so that the latching portion 221 moves to the first position to be disengaged from the lock tongue 11, at this time, the male buckle 10 can be separated from the female buckle 20.

[0076] Embodiment 2

[0077] The male buckle 10 of this embodiment is structured the same as in Embodiment 1.

[0078] The female buckle 20 includes a housing 25, a latching member 22, an unlocking member 26, a first magnetic member 21, and a second magnetic member 12.

[0079] As shown in FIGS. 3-4, the housing 25 is used to house the latching member 22, the unlocking member 26, and the first magnetic member 21, and can be structured as desired. Typically, for ease of manufacture and assembly, it generally includes a first housing 251 and a second housing 252 that are connected together. When the first housing 251 and the second housing 252 are connected together, an internal cavity is formed therein that can be used to house the latching member 22, the unlocking member 26, and the first magnetic member 21. In addition, for ease of positioning the first magnetic member 21, a magnet holder 253 can be provided in the internal cavity as desired.

[0080] For ease of insertion of the locking tongue 11 of the male buckle 10 into the female buckle 20, the lock hole 24 is provided on the housing 25. The shape of the lock hole 24 can be structured as desired, and in this embodiment it is a circular hole.

[0081] As shown in FIGS. 3-4, the first magnetic member 21 is positioned in the female buckle 20 such that it is opposite the position of the lock hole 24, so that it can be easily attracted to the second magnetic member 12 in the locking tongue 11.

[0082] The unlocking member 26 is used for unlocking operations, and is movably disposed in the female buckle 20, and can be moved in a third direction that is perpendicular to the locking direction.

[0083] The latching member 22 includes a latching portion 221, a magnet mounting portion 223, and a linkage portion 225 that are fixedly connected or integrally formed.

[0084] The latching portion 221 can be engaged with the locking tongue 11 to cause the male buckle 10 and the female buckle 20 to be engaged together. The latching portion 221 can be inserted into the groove portion 111 of the locking tongue 11 in a second direction, so that the locking tongue 11 and the latching member 22 are engaged together.

[0085] The magnet mounting portion 223 is provided with a magnet mounting groove 2231 that is used to mount the third magnetic member 23. The third magnetic member 23 is mounted in the magnet mounting groove 2231 and is linked with the latching member 22.

[0086] The linkage portion 225 is linked with the unlocking member 26, and can be actuated by the linkage of the unlocking member 26 to cause the latching member 22 to move from the second position to the first position.

[0087] Further, the third direction is perpendicular to the first direction and the second direction.

[0088] Further, the unlocking member 26 comprises a pressing part 261, an elastic arm 262 and a linkage column 263.

[0089] The pressing part 261 is provided with two, which are oppositely spaced and partially exposed in the shell 25 of the female buckle 20. The pressing part 261 is unlocked by pressing towards each other.

[0090] The elastic arm 262 is connected between the pressing part 261, so that the unlocking member 26 is annular as a whole, or two half annular.

[0091] The linkage column 263 is provided on the elastic arm 262, which is arranged along the locking direction, and is used to push the linkage part 225 to drive the locking member 22.

[0092] The number of linkage columns 263 can be arranged as needed. In the embodiment, the linkage column 263 is provided on the elastic arm 262 with the first direction as the axis of symmetry. Correspondingly, the linkage part 225 is symmetrically arranged on the end of the magnet mounting part 223 away from the locking part 221 with the first direction as the axis of symmetry.

[0093] The locking member 22 is movably arranged in the shell 25, and can move along the first direction and the second direction.

[0094] The elastic arm 262 is arranged on the locking member 22, and the linkage column 263 faces the locking member 22. The linkage part 225 is provided with an action surface 2251 facing the linkage column 263, and the action surface 2251 is arranged at an angle with the first direction and the third direction. When the linkage column 263 moves, the linkage column 263 acts on the action surface 2251, thereby driving the locking member 22 to move along the first direction and exit the lock hole 24.

[0095] The default position of the locking part 221 is affected by the magnetic force between the third magnetic member 23 and the first magnetic member 21, which can be in the first position, or in the second position, or in any position between the first position and the second position.

[0096] When the lock tongue 11 is inserted along the locking direction, in the first stage, the third magnetic member 23 repels the second magnetic member 12, so that the locking part 221 remains in the first position, or moves to the first position along the first direction.

[0097] When the default state of the locking part 221 is at the first position, in the first stage, the magnetic repulsion force between the third magnetic part 23 and the second magnetic part 12 does not actuate the locking part 22, and the locking part 22 remains at the first position.

[0098] When the default state of the locking part 221 is not at the first position, in the first stage, the magnetic repulsion force between the third magnetic part 23 and the second magnetic part 12 actuates the locking part 22 to move in the first direction to the first position.

[0099] When the locking tongue 11 continues to advance, the magnetic force between the third magnetic part 23 and the second magnetic part 12 changes to the second stage, at which the third magnetic part 23 and the second magnetic part 12 attract each other, thereby actuating the locking part 22 to move in the second direction from the first position to the second position, so as to be engaged with the locking tongue 11 to achieve the engagement connection of the male buckle 10 and the female buckle 20.

[0100] When the female buckle 20 and the male buckle 10 are engaged, and unlocking is needed, the pressing part 261 is pressed in the opposite direction, the elastic arm 262 is elastically deformed to change the position of the linkage column 263, thereby pushing the linkage part 225 to move the locking part 22 in the first direction as a whole, so as to move the locking part 221 to the first position to be disengaged from the locking tongue 11, at which the male buckle 10 can be separated from the female buckle 20.

[0101] Further, to restrict the deformation of the elastic arm 262, a protruding limiting column 254 is arranged in the housing 25, and the limiting column 254 extends in the locking direction. The middle part of the elastic arm 262 is sleeved on the limiting column 254.

[0102] Further, to restrict the displacement of the locking part 22, a limiting groove 255 is arranged on the housing 25, and a protruding column part 226 is arranged on the linkage part 225. The column part 226 is located in the limiting groove 255, so that the locking part 22 can only move within the stroke range of the limiting groove 255.

[0103] Although the present application is disclosed by the above embodiments, the scope of the present application is not limited thereto, and each component can be replaced by similar or equivalent elements known by those skilled in the art without departing from the concept of the present application.
