[ detailed description ] embodiments

The following examples are further illustrative and supplementary to the present invention and do not limit the present invention in any way.

As shown in fig. 1 and 11, the fastener device to be unlocked by pulling of the present invention includes a first connection module 10 and a second connection module 20.

As shown in fig. 10, 11 and 12, the first connection module 10 and the second connection module 20 are lockable together and separable from each other. The first connection module 10 is provided with a lock tongue 11, the second connection module 20 is provided with a corresponding lock hole 21, and the lock tongue 11 can be inserted into the lock hole 21 along the locking direction X so that the first connection module 10 and the second connection module 20 are locked and connected together; when unlocked, the latch 11 can be withdrawn from the lock hole 21 to separate the first connection module 10 and the second connection module 20 from each other.

As shown in fig. 10, 11 and 12, in order to facilitate the quick locking of the first connection module 10 and the second connection module 20, a first magnet 12 is disposed in the first connection module 10, and a second magnet 24 is disposed in the second connection module 20. The first magnet 12 and the second magnet 24 are attracted to each other. When the latch bolt 11 is facing the lock hole 21 to be inserted, the magnetic force between the first magnet 12 and the second magnet 24 may assist the latch bolt 11 to be quickly inserted into the lock hole 21.

As shown in fig. 10, 11 and 12, the second connection module 20 is provided with an unlocking member 23 and a locking portion 231. The latch 231 may be moved by the actuation of the unlocking member 23. In some embodiments, as shown in fig. 2 and fig. 6, the latching portion 231 is integrally designed with the unlocking member 23, that is, the latching portion 231 is a part of the unlocking member 23. In some embodiments, as shown in fig. 5 and 9, the latching portion 231 is disposed separately from the unlocking member 23, that is, the latching portion 231 is an element other than the unlocking member 23.

As shown in fig. 10, 11 and 12, the unlocking member 23 is movably disposed in the second connection module 20, and can be pulled in a direction transverse to the locking direction. As shown in fig. 11, the direction X is a locking direction, the direction Y is perpendicular to the direction X, and the unlocking member 23 can be pulled outward in the direction Y. In the present embodiment, the relative directions of the outward direction, the inward direction, the outward direction, and the like are common to the unlocking member 23.

The unlocking piece 23 may actuate the latching portion 231. As shown in fig. 10, 11 and 12, the unlocking member 23 is provided with a pulling portion 233, and the pulling portion 233 is used for a user to pull the unlocking member 23 outward. The pulling portion 233 may be a rigid structure or a flexible structure. The specific shape of the pulling portion 233 is not limited, and it is preferable for the user to pull it conveniently. For example, the pulling portion 233 may be provided in the form of an outwardly extending pull rod, or in the form of a pull string, or in the form of a pull ring, etc.

When the unlocking member 23 is movably disposed in the housing 22 of the second connection module 20, a part or the whole of the pulling portion 233 is located outside the housing 22 of the second connection module 20 so as to be pulled. The pulling part 233 may be shaped and sized as needed.

As shown in fig. 10, 11 and 12, the unlocking member 23 is located inside the second connection module 20 except for the pulling portion 233.

As shown in fig. 10 and 12, the locking portion 231 may lock the locking tongue 11 so that the first connection module 10 and the second connection module 20 are connected to each other.

As shown in fig. 11, the latch 231 is a part of the lock hole 21. The second connection module 20 is provided with a fixing hole 223. The fixing hole 223 is sized to allow the latch 11 to freely enter and exit. The fixing hole 223 and the latching part 231 together form a locking hole 21 that can latch the latch tongue 11. The lock hole 21 locks or releases the latch 11 by a change in position of the latching portion 231. As shown in fig. 11, when the latching part 231 is protruded within the range of the fixing hole 223, it has a capability of latching the latch 11, and at this time, the first connection module 10 and the second connection module 20 may be connected to each other. When the latching part 231 moves in a direction of withdrawing from the fixing hole 223 to some extent, the latching part 231 loses the ability to latch the latch tongue 11, and the first connection module 10 and the second connection module 20 may be separated from each other.

As shown in fig. 11, the latching portion 231 protrudes into the range of the fixing hole 223 in a default state, and the latching portion 231 may move in a pulling direction of the unlocking piece 23 to exit the range of the fixing hole 223 by being actuated by the unlocking piece 23.

When the unlocking piece 23 is pulled outwards, the unlocking piece 23 moves outwards to actuate the latching part 231, so that the latching part 231 can be withdrawn outwards from the range of the fixing hole 223 to release the lock tongue 11 for unlocking.

Further, as shown in fig. 2 to 12, in order to allow the latch 231 after the movement to be reset to a default state, i.e., to extend out of the fixing hole 223, a first elastic connection portion 234 is provided at one end of the latch 231, which is far from the fixing hole 223. The first elastic connection portion 234 has elasticity, and thus, the movement of the latching portion 231 can be satisfied and the latching portion 231 can be reset by the elasticity.

In some embodiments, as shown in fig. 2 and 6, the first elastic connection portion 234 is integrally connected to the unlocking member 23.

In some embodiments, as shown in fig. 5 and 9, the first elastic connection portion 234 is not connected to the unlocking member 23, but is fixedly connected or detachably connected to the housing 22 of the second connection module 20.

When the latching portion 231 is moved in a direction of withdrawing from the fixing hole 223 by the actuation of the unlocking piece 23, the first elastic connection portion 234 is compressed to store force. When the external tensile force is lost, the first elastic connection portion 234 is restored by the elastic force to move the latching portion 231 toward the fixing hole 223 and is restored to a range protruding out of the fixing hole 223.

Further, as shown in fig. 2 to 12, in order that the unlocking unit 23 may actuate the latching unit 231 to release the latch tongue 11, the unlocking unit 23 is provided with a pressing portion 237, and the latching unit 231 is provided with a pushing portion 238. The pressing portion 237 is rigidly formed on the unlocking member 23. When the unlocking member 23 is pulled outward, the pressing portion 237 moves along with the unlocking member 23 to push the pushing portion 238, so as to drive the latching portion 231 to move in the pulling direction and gradually exit the range of the fixing hole 223, thereby releasing the locking tongue 11.

As shown in fig. 2 to 9, in order to automatically restore the unlocking member 23 pulled outward, a second elastic connection portion 235 is provided on the unlocking member 23. The second elastic connection portion 235 has elasticity, which is provided in a pulling direction, and abuts against the housing 22 of the second connection module 20. To facilitate the abutting of the second elastic connection portion 235, a stopper 225 is provided in the housing 22 of the second connection module 20. The stopper 225 is fixedly disposed, and its position does not change with the movement of the unlocking member 23. The end of the second elastic connection portion 235 abuts against the stopper 225. When the unlocking member 23 is pulled outward, the second elastic connection portion 235 is pressed by the stopper 225 to be compressed, thereby accumulating elastic force. When the unlocking member 23 loses the external pulling force, the second elastic connection portion 235 is reset to force the unlocking member 23 to move in the direction opposite to the pulling direction to be reset.

To facilitate the provision of the second elastic connection portion 235 and the pressing portion 237, the unlocking member 23 is provided with a cantilever having a long rod shape. The cantilever is in a long rod shape and has certain rigidity.

The second elastic connection portion 235 is connected to an outer side of an end portion of the other end of the cantilever opposite to the pulling side.

One end of the second elastic connection portion 235 is integrally connected to the cantilever, and the other end thereof is a free end. The free end of the second elastic connection portion 235 extends along the pulling side of the unlocking member 23 to abut against the stopper 225, so that the unlocking member 23 can be compressed and accumulated when being pulled outward.

The pressing portion 237 is provided on an inner wall of the cantilever, and preferably, the pressing portion 237 is rigidly formed on the inner wall of the cantilever, and is integrally formed with the cantilever.

Further, as shown in fig. 2 to 9, the cantilever may include a first cantilever 2391 and a second cantilever 2392 which are spaced apart from each other. The first and

second cantilever arms

2391 and 2392 may be integrally coupled to each other at ends thereof close to the pulling side, and may be integrally connected to the pulling portion 233. The outer sides of the free ends of the first cantilever 2391 and the second cantilever 2392 are respectively provided with the second elastic connecting portion 235. The pressing portions 237 are rigidly provided on the inner walls of the first and

second cantilever arms

2391 and 2392, respectively. Preferably, the pressing portions 237 are symmetrically disposed on the first and

second suspension arms

2391 and 2392. The latching portion 231 is disposed between the first suspension arm 2391 and the second suspension arm 2392, and is spaced apart from the first suspension arm 2391 and the second suspension arm 2392.

Further, as shown in fig. 6, 8, 9, 11, and 12, in order to reduce the opening force during unlocking, a push-out portion 232 may be provided on the unlocking member 23. As shown in fig. 11 and 12, the extruding part 232 may extend out of the fixing hole 223 and may move in a pulling direction. When the unlocking member 23 is pulled outward, the extruding part 232 may push the locking tongue 11 to move in a direction away from the second connection module 20, thereby facilitating the separation of the first connection module 10 and the second connection module 20.

As shown in fig. 6, 8 and 9, the extrusion portion 232 is provided inside the free end of the cantilever. In other words, the extruding portion 232 and the second elastic connecting portion 235 are distributed on different sides of the cantilever. The extrusion 232 is arranged transversely to the cantilever and spaced apart from the latching 231.

Further, as shown in fig. 6, 8 and 9, the extrusion 232 is transversely connected between the free ends of the first and

second cantilevers

2391 and 2392, and is integrally connected with the first and

second cantilevers

2391 and 2392.

Further, as shown in fig. 11 and 12, an extrusion inclined curved surface 2321 is provided on a side of the extrusion portion 232 facing the fixing hole 223, and a first conical surface 111 is provided on a free end of the latch bolt 11. As shown in fig. 12, the extrusion ramp 2321 may be engaged with the first conical surface 111. When the unlocking member 23 is pulled outward, the extruding portion 232 moves in the pulling direction, and the extruding inclined curved surface 2321 of the extruding portion acts on the first conical surface 111 of the latch tongue 11 to push out the latch tongue 11 in the locking direction, thereby assisting the separation of the first connection module 10 and the second connection module 20. As shown in fig. 12, when the first connection module 10 and the second connection module 20 are connected to each other, the inclined extrusion curved surface 2321 of the extrusion portion 232 is located on the first conical surface 111 of the latch bolt 11 or attached to the first conical surface 111.

In addition, the extruding part 232 can also extrude into the position where the first magnet 12 and the second magnet 24 are combined to reduce the attraction force between the first magnet 12 and the second magnet 24, thereby facilitating the exit of the locking bolt 11. When the unlocking member 23 is pulled outward, the extruding part 232 moves in a pulling direction to space the first magnet 12 and the second magnet 24 apart to reduce the magnetic attraction therebetween, thereby facilitating the separation of the first connection module 10 and the second connection module 20.

The working principle of the buckle device unlocked by pulling comprises the following steps:

as shown in fig. 11, when the first connection module 10 and the second connection module 20 are brought close to each other in the locking direction, the magnetic attraction between the first magnet 12 and the second magnet 24 allows the latch 11 to be quickly inserted into the locking hole 21 to connect the first connection module 10 and the second connection module 20 together (see fig. 10 and 12). In the default state, the latching portion 231 is located within the range of the fixing hole 223 to block the latch 11. Since the latching part 231 is connected to the first elastic connection part 234, the latching part 231 may be positionally changed. In the process that the lock tongue 11 is inserted into the lock hole 21, the lock tongue 11 can push the latching part 231, so that the latching part 231 firstly moves to a certain extent in the direction away from the fixing hole 223, and the lock tongue 11 can enter; in this process, the first elastic connecting portion 234 is compressed to store power; as the bolt 11 completely enters, the latching portion 231 loses the pushing force of the bolt 11, and at this time, under the action of the first elastic connecting portion 234, the bolt can move toward the fixing hole 223 and extend into the range of the fixing hole 223, so as to achieve the reset, and latch the bolt 11, so that the bolt 11 cannot actively exit from the lock hole 21.

When unlocking is required, the unlocking piece 23 is pulled outwards, the pressing part 237 acts on the pushing part 238 of the latching part 231 along with the movement of the unlocking piece 23, so that the latching part 231 is pushed to move in the pulling direction, the latching part 231 is withdrawn outwards from the range of the fixing hole 223 to release the locking tongue 11, and at this time, the locking tongue 11 can be separated from the second connection module 20 to separate the first connection module 10 and the second connection module 20 from each other.

In the unlocking process, the unlocking member 23 compresses the second elastic connecting portion 235 when being pulled outwards, and the locking portion 231 compresses the first elastic connecting portion 234 when being withdrawn outwards from the range of the fixing hole 223, so that the first elastic connecting portion 234 and the second elastic connecting portion 235 are both compressed and accumulate force when being unlocked. After the latch 11 is released from the second connection module 20, if the user releases the unlocking member 23, the unlocking member 23 moves inward as a whole to be reset under the elastic force of the second elastic connection part 235; the latching portion 231 is moved inward to be reset by the elastic force of the first elastic connection portion 234, and may be finally reset to a default state.

When the extrusion portion 232 is provided, as shown in fig. 12, when unlocking, the extrusion portion 232 may act on the end of the latch tongue 11 to facilitate the latch tongue 11 to move away from the second connection module 20, thereby further facilitating the separation of the first connection module 10 and the second connection module 20 from each other.

As shown in fig. 2, the housing 22 is used to provide the unlocking member 23 and the second magnet 24, and its shape and structure may be set as desired. Typically, to facilitate assembly, it typically includes first housing 22122 and second housing 22222 joined together in a butt-fit manner. When the first housing 22122 and the second housing 22222 are connected together, a receiving cavity is formed inside, and the receiving cavity can be used for accommodating the unlocking member 23 and the second magnet 24. In addition, in order to facilitate the arrangement of the second magnet 24, a magnet holder 25 may be provided inside thereof, and the shape and structure of the magnet holder 25 may be arranged as needed, which is preferable to facilitate the arrangement of the second magnet 24.

As shown in fig. 2, in order to facilitate the insertion of the latch 11 of the first connection module 10 into the second connection module 20, the housing 22 is provided with the fixing hole 223. The fixing hole 223 is shaped as required, and in this embodiment, it is a circular hole.

As shown in fig. 2 and 3, a stopper 225 is disposed outside the fixing hole 223 to facilitate the contact with the second elastic connection portion 235. The stoppers 225 are protruded and symmetrically disposed at both sides of the fixing hole 223.

As shown in fig. 10, the position of the second magnet 24 in the second connection module 20 is opposite to the position of the fixing hole 223, so that the second magnet can be easily attracted to the first magnet 12 in the latch 11.

As shown in fig. 2 and 4, one end of each of the first and

second cantilever arms

2391 and 2392 is integrally coupled to the pulling portion 233, and the other end is a free end.

The shape and number of the first elastic connection portions 234 may be set as desired. In this embodiment, the first elastic connection portion 234 is formed in a wavy bent shape, and the bent direction thereof is parallel to the axial direction of the fixing hole 223.

As shown in fig. 2, 3, and 4, the second elastic connecting portion 235 is distributed outside the first cantilever 2391 and the second cantilever 2392, one end of the second elastic connecting portion is integrally connected to the free ends of the first cantilever 2391 and the second cantilever 2392, and the other end of the second elastic connecting portion faces the pulling side to form a free end and abuts against the stopper 225. The shape of the second elastic connection portion 235 is not limited, in this embodiment, the second elastic connection portion 235 is in a wavy bent shape, and the bending direction thereof is parallel to the axial direction of the fixing hole 223.

As shown in fig. 2, 3 and 4, one end of the latching portion 231 facing the extruding portion 232 is arc-shaped, and is used for latching the latch tongue 11. As shown in fig. 10, in order to facilitate the locking tongue 11 to be pushed into the locking hole 21 to achieve the locking connection, a lead-in inclined curved surface 2311 is provided at a side of the locking part 231 facing the fixing hole 223. The guiding inclined curved surface 2311 is beneficial to the extrusion of the lock tongue 11 and is extruded into the lock hole 21 in a proper position, so that the locking part 231 can lock the lock tongue 11.

As shown in fig. 2, 3, and 4, the pressing portions 237 are symmetrically distributed on inner walls of the first suspension arm 2391 and the second suspension arm 2392, and are convex relative to the inner walls of the first suspension arm 2391 and the second suspension arm 2392.

As shown in fig. 2, 3, and 4, the pushing portion 238 is provided on a wall portion of the latching portion 231 facing the pressing portion 237. The pushing portion 238 is protruded with respect to the wall surface around it, so that an action space is provided for the pressing of the pressing portion 237. In a default state, the pushing portion 238 is spaced from the pressing portion 237 without contacting. When the unlocking member 23 is pulled outward, the pressing portion 237 is changed in position to contact the pushing portion 238 to push the pushing portion 238. The pushing portion 238 is located on a side of the pressing portion 237 facing the pulling portion 233, so that the pressing portion 237 can push the pushing portion 238 along the direction of the pulling portion 233, thereby forcing the latching portion 231 to move in the pulling direction and to exit the range of the fixing hole 223, thereby facilitating the disengagement of the locking bolt 11. In this embodiment, two pushing portions 238 are symmetrically disposed and respectively distributed on the wall portions at the two ends of the latching portion 231.

As shown in fig. 2, the second connection module 20 is thus formed: the unlocking piece 23 is movably arranged in the shell 22; the housing 22 is provided with a fixing hole 223, the unlocking member 23 is provided with a locking portion 231, and the locking portion 231 extends out of the fixing hole 223 in a default state to form a locking hole 21 for locking the lock tongue 11 together with the fixing hole 223. The latch 231 may be actuated by the unlocking member 23 to outwardly exit the range of the fixing hole 223 to release the latch 11. The pulling portion 233 of the unlocking member 23 is at least partially located outside the housing 22 and is available for pulling, and the first elastic connecting portion 234, the second elastic connecting portion 235, the latching portion 231, the pressing portion 237, the pushing portion 238, the first cantilever 2391, and the second cantilever 2392 of the unlocking member 23 are all located inside the housing 22.

As shown in fig. 2 and 10, the first connecting module 10 is provided with a latch 11, the latch 11 is protruded, and the end thereof is truncated cone-shaped and provided with a first conical surface 111. The first conical surface 111 is used for pressing the lead-in oblique curved surface 2311 to facilitate the bolt 11 to enter the lock hole 21, and meanwhile, the first conical surface 111 is also used for interacting with the lead-out oblique curved surface 2321 to facilitate the bolt to exit from the lock hole 21 during unlocking.

As shown in fig. 10, the latch 11 is provided with a groove portion 112 for cooperating with the latch portion 231 to achieve a locking effect. The groove portion 112 is located slightly away from the end surface of the bolt 11. In this embodiment, the groove portion 112 is annular. In other embodiments, the groove portion 112 may also be configured to match the shape and size of the latching portion 231. The groove portion 112 is provided with a second conical surface 113113 having an inclination matching the latching portion 231. When the lock tongue 11 presses the latch portion 231 and pushes the lock hole 21, the latch portion 231 is latched in the groove portion 112, so that the first connection module 10 and the second connection module 20 are connected together in a locked manner.

As shown in fig. 10, in order to facilitate the quick locking of the first connection module 10 and the second connection module 20, a first magnet 12 is disposed in the latch 11. The arrangement direction of the first magnet 12 can be set according to the requirement, in this embodiment, the bolt 11 is in a hollow cylinder shape, the first magnet is installed inside the hollow bolt 11, and then the opening can be sealed by the sealing cover so that the first magnet 12 is sealed inside the bolt 11.

Therefore, the buckle device capable of being unlocked by pulling in the embodiment is formed, and the working principle is as follows:

when the first connection module 10 and the second connection module 20 are close to each other in the locking direction, the magnetic attraction between the first magnet 12 and the second magnet 24 will cause the latch 11 of the first connection module 10 to be inserted into the latch hole 21 of the second connection module 20 in alignment. During the insertion process, the latch 231 is provided with the guiding inclined curved surface 2311, and the latch 231 is provided through the first elastic connecting portion 234, so that the latch 11 can press the latch 231 and enter the second connection module 20, so that the latch 231 is latched in the groove portion 112 of the latch 11, and the first connection module 10 and the second connection module 20 are lockingly connected (as shown in fig. 10).

When unlocking is required, the unlocking member 23 is pulled outward, and the pressing portion 237 moves outward along with the unlocking member 23. In the locked state, the latching portion 231 is usually pressed by the lock tongue 11, and the tendency of directly following the movement of the unlocking member 23 may be hindered, so that the outward movement of the pushing portion 238 and the latching portion 231 lags behind the pressing portion 237. When the pressing portion 237 moves outward to contact with the pushing portion 238, the pressing portion 237 pushes the pushing portion 238, so that the latching portion 231 moves outward, the latching portion 231 exits the range of the fixing hole 223 to release the locking tongue 11, and the first connection module 10 and the second connection module 20 can be separated from each other.

During unlocking, the unlocking member 23 is pulled outward to compress the second elastic connection portion 235, so that the second elastic connection portion 235 is compressed to store force. The latch 231 moves to compress the first elastic connection portion 234, so that the first elastic connection portion 234 is compressed to store force. After the latch 11 is released from the second connection module 20, if the user releases the unlocking member 23, the unlocking member 23 may be completely reset to the default state by the elastic force of the second elastic connection part 235 and the first elastic connection part 234.

Example 2

The basic structure of this embodiment is the same as that of the embodiment, except that, as shown in fig. 6, 7, and 8, an extruded portion 232 is connected between the free ends of the first and

second cantilevers

2391 and 2392. In other words, as shown in fig. 6 and 8, the unlocking member 23 includes a pulling portion 233, a first elastic connecting portion 234, a latching portion 231, a second elastic connecting portion 235, a pressing portion 237, a pushing portion 238, an extruding portion 232, a first cantilever 2391, and a second cantilever 2392, which are integrally formed.

As shown in fig. 11 and 12, in order to facilitate the extrusion portion 232 to push the locking tongue 11 to move so as to facilitate unlocking, an extrusion inclined curved surface 2321 is provided on a side of the extrusion portion 232 facing the fixing hole 223. The design of the extrusion inclined curved surface 2321 makes the orientation of the extrusion part 232 the end of the latch part 231 is sharp, and then can be conveniently extruded between the attraction parts of the first magnet 12 and the second magnet 24, namely, between the end surface of the lock tongue 11 and the magnet frame 25, so as to reduce the magnetic attraction between the first magnet 12 and the second magnet 24, thereby facilitating the exit of the lock tongue 11. In addition, the extruded oblique curved surface 2321 may also act on the free end of the latch bolt 11 to push the latch bolt 11 to move in the locking direction to exit the lock hole 21. When the first connection module 10 and the second connection module 20 are locked together, the inclined extrusion curved surface 2321 of the extrusion portion 232 is located above the first conical surface 111 of the latch bolt 11, or attached to the first conical surface 111 (as shown in fig. 12).

The extrusion part 232 has the following action principle:

when the unlocking member 23 is pulled outward, the extruding part 232 moves along the pulling direction, that is, moves in the direction of entering the fixing hole 223, so as to extrude between the combining portions of the first magnet 12 and the second magnet 24 to reduce the magnetic force between the first magnet 12 and the second magnet 24, and force the latch tongue 11 to move away from the second connection module 20 by the extruding inclined curved surface 2321 to separate the first connection module 10 from the second connection module 20.

The latch member 26 is connected to the housing 22 by the latch posts 236 being snapped into the latch holes 224.

The working principle of the embodiment is as follows:

when the first connection module 10 and the second connection module 20 are close to each other in the locking direction, the magnetic attraction between the first magnet 12 and the second magnet 24 will cause the latch 11 of the first connection module 10 to be inserted into the latch hole 21 of the second connection module 20 in alignment. In the inserting process, the guiding inclined curved surface 2311 is arranged on the locking portion 231, and the locking portion 231 is arranged through the first elastic connecting portion 234, so that the locking tongue 11 can press the locking portion 231 to enter the second connecting module 20, so that the locking portion 231 is locked in the groove portion 112 of the locking tongue 11, and the first connecting module 10 is locked and connected with the second connecting module 20.

When unlocking is required, the unlocking member 23 is pulled outward, and the pressing portion 237 moves outward along with the unlocking member 23.
