Description

Technical Field

[0001] The invention relates to the field of buckles, and in particular to a draw wire lock device. Background Art

[0002] Male buckles and female buckles are widely used in detachable connection scenarios. For ease of use, magnets are often provided in the male buckles and female buckles to assist in quick attraction.

[0003] In daily life, some scenes require detachable connection through a long rope, for example, a drawstring for walking the dog, one end of the drawstring is provided with a male buckle (or female buckle), and the female buckle (or male buckle) is connected to the neck of the pet dog through a ring. Through the engagement of the male buckle and the female buckle, the drawstring can be tied to the pet dog, and when necessary, the drawstring can be quickly removed from the pet dog.

[0004] Normally, the unlocking operating member for separating the male buckle and the female buckle is set on the female buckle. However, for scenarios such as walking the dog, for ease of use, the unlocking operating member is set at a position far away from the male and female buckles. The unlocking operating member is connected to the male and female buckle structure through a pull wire. In this way, the male and female buckles at the far end can be controlled to be unlocked through the unlocking operating member.

[0005] In addition to dog walking, there are many similar scenarios where the release operating element is separated from the male and female buckles and is unlocked by pulling a wire. In actual application, the pull wire is movably arranged in the corresponding fabric. For example, for a dog walking leash, the pull wire for linkage unlocking is movably arranged in the dog leash.

[0006] However, most fabrics have a certain elongation. When the external force applied to the fabric reaches a certain level, the fabric will stretch, and the pull cord will move to adapt to the stretch of the fabric. When the length of the fabric extension is similar to the unlocking travel of the pull cord, the pull cord will be linked to unlock the male and female buckles, resulting in accidental unlocking. For example, for a pull cord used for walking a dog, it will not be accidentally released due to the elongation of the pull cord. However, when a pet dog suddenly runs away, it will exert a large tensile force on the pull cord, causing the pull cord material to stretch. At this time, the stretch of the fabric material will cause an accidental release. Therefore, the existing pull cord locks of this type need to be improved to avoid accidental release. Summary of the invention

[0054] The following examples are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0055] like Figure 1-Figure 10 As shown, the pull-wire lock device of the present invention comprises a release operating member 10, a pull wire 20 and an interlocking assembly 30. The pull wire 20 is connected between the release operating member 10 and the interlocking assembly 30, wherein the first end 21 of the pull wire 20 is connected to the release operating member 10, and the second end 22 of the pull wire 20 is connected to the interlocking assembly 30. The release operating member 10 is used for the user to operate at a remote end to release the lock. By operating the release operating member 10, the user can pull the pull wire 20, thereby linking the interlocking assembly 30 to release the lock.

[0056] The release operating member 10 is an operating element, the pull wire 20 is an action transmission element, and the interlocking assembly 30 is an unlocking actuator. In order to prevent the interlocking assembly 30 from being accidentally released due to external factors acting on the pull wire 20, the pull wire 20 is at least partially movable in a buffer zone. The pull wire 20 can offset the activity or possible activity caused by external factors acting on the pull wire 20 by moving a certain distance in the buffer zone, so that the interlocking assembly 30 is unlocked without being affected by external factors. In this way, only the activity of the release operating member 10 can effectively pull the interlocking assembly 30 to release the lock, and other external factors will not pull the interlocking assembly 30 to release the lock when the pull wire 20 moves, thereby avoiding accidental release and improving the safety of use.

[0057] Furthermore, the external factor does not include the unlocking operating member 10 .

[0058] Furthermore, the external factor refers to a factor other than the unlocking operating member 10 that can act on the pull wire 20 and cause the pull wire 20 to move relative to the interlocking assembly 30 .

[0059] For example, when a connecting belt 40 is provided between the unlocking operating member 10 and the interlocking assembly 30, and the connecting belt 40 is an elastic belt, or the connecting belt 40 is extended under certain conditions to cause the distance between the unlocking operating member 10 and the interlocking assembly 30 to change, if the pull wire 20 is not provided in the above manner, the change in the distance between the unlocking operating member 10 and the interlocking assembly 30 will cause the pull wire 20 to move relative to the interlocking assembly 30, which is equivalent to pulling to unlock and causing the interlocking assembly 30 to be released. The extension of the connecting belt 40 and the change in the distance between the unlocking operating member 10 and the interlocking assembly 30 can be referred to as the external factors.

[0060] When external factors act on the pull wire 20, it should cause the pull wire 20 to move relative to the interlocking assembly 30. However, the movement of the pull wire 20 in the buffer zone can offset this movement or offset this movement trend, making it impossible for the pull wire 20 to link with the interlocking assembly 30 to release the lock. The lock can only be released when the release operating member 10 moves.

[0061] For the convenience of description, when the pull wire 20 pulls the interlocking assembly 30 to release the lock, the direction of the pulling force applied by the pull wire 20 to the interlocking assembly 30 is referred to as the pulling direction X.

[0062] When the pull wire 20 moves in the buffer zone, it can at least move in a direction different from the pulling direction X. The direction different from the pulling direction X includes a direction inclined to the pulling direction X and a direction parallel to the pulling direction X but opposite to it.

[0063] In this embodiment, at least a portion of the pull wire 20 is wound in the buffer zone, and the winding portion 23 formed by the pull wire 20 can shrink or expand in the buffer zone. The winding portion 23 is annular, and when it shrinks or expands, its moving direction will be different from the pulling direction X.

[0064] When the pull wire 20 is affected by external factors, the pull wire 20 is pulled, and the winding portion 23 thereof can move in the buffer zone and shrink, thereby increasing the length of the pull wire 20 outside the buffer zone, thereby offsetting the movement caused by the external factors acting on the pull wire 20, so that the pull wire 20 will not have a pulling effect on the interlocking assembly 30. In this way, the interlocking assembly 30 will maintain the current state and will not be accidentally released.

[0065] Furthermore, the pull wire 20 has certain shape memory properties, especially the winding portion 23 has certain shape memory properties. When the pull wire 20 is pulled as a whole, the winding portion 23 will shrink and change its shape. When the external factors acting on the pull wire 20 are removed, the winding portion 23 can automatically restore its original shape or a shape similar to its original shape.

[0066] Furthermore, the release operating member 10 is movably disposed in the lock housing 50, and a connecting belt 40 is disposed between the lock housing 50 and the interlocking assembly 30. The first end 41 of the connecting belt 40 is connected to the lock housing 50, and the second end 42 of the connecting belt 40 is connected to the interlocking assembly 30. The pull wire 20 passes through the interior of the connecting belt 40 along the length direction of the connecting belt 40 and passes out from both ends of the connecting belt 40 to be connected between the interlocking assembly 30 and the release operating member 10.

[0067] In the default state, the connecting belt 40 is at a natural length, the pull wire 20 is movably arranged inside the connecting belt 40, and the length of the pull wire 20 inside the connecting belt 40 is consistent with the length of the connecting belt 40. When the connecting belt 40 is extended under the action of external force, the distance between the lock housing 50 and the interlocking assembly 30 increases. At this time, the pull wire 20 will move in the buffer zone so that the pull wire 20 automatically adapts to the extension of the connecting belt 40, so that the influence of the extension of the connecting belt 40 on the pull wire 20 can be offset, and the pull wire 20 is prevented from moving relative to the interlocking assembly 30 due to the extension of the connecting belt 40, thereby preventing the interlocking assembly 30 from being accidentally released.

[0068] The extension of the connecting belt 40 under the action of external force (ie, the length of the connecting belt 40 is greater than the natural length of the connecting belt 40 ) is the external factor that affects the pull wire 20 described in this embodiment.

[0069] In this embodiment, the connecting belt 40 is a webbing. When the tension applied to the connecting belt 40 is greater than a predetermined value, it will stretch to a certain extent.

[0070] Furthermore, the buffer zone is disposed in the lock housing 50 .

[0071] The interlocking assembly 30 includes a female buckle 31. The female buckle 31 includes a female buckle seat 311 and an interlocking member 312 movably disposed in the female buckle seat 311. The interlocking member 312 can move relative to the female buckle seat 311 under the action of the pull wire 20.

[0072] The pull wire 20 includes a pull core wire 201 and a wire sleeve 202 .

[0073] The first end 2021 of the wire sleeve 202 is fixedly arranged relative to the lock housing 50, and the connection therebetween may be fixed or detachable. Regardless of how the wire sleeve 202 is connected to the lock housing 50, the position of the first end 2021 of the wire sleeve 202 in the lock housing 50 is fixed. The material of the wire sleeve 202 is not limited. In this embodiment, the wire sleeve 202 is made of plastic.

[0074] The second end 2022 of the wire sleeve 202 is fixedly arranged with the female buckle seat 311, and the connection therebetween can be fixed or detachable. Regardless of how the wire sleeve 202 is connected to the female buckle seat 311, the relative position of the second end 2022 of the wire sleeve 202 and the female buckle seat 311 is fixed.

[0075] The pull core wire 201 is movably arranged in the wire sleeve 202, and can be pulled relative to the wire sleeve 202. The first end 2011 of the pull core wire 201 extends out of the first end 2021 of the wire sleeve 202 and is connected to the unlocking operation member 10. The second end 2012 of the pull core wire 201 extends out of the second end 2022 of the wire sleeve 202 and is connected to the interlocking member 312. The pull core wire 201 should have a certain strength. In this embodiment, the pull core wire 201 is a metal wire. When it is bent to form the winding portion 23, it has a certain shape memory and retention ability.

[0076] When the unlocking operating member 10 moves, the core wire 201 is pulled, the core wire 201 can be pulled relative to the wire sleeve 202, and the core wire 201 can drive the interlocking member 312 to move relative to the female buckle seat 311. In this process, only the core wire 201 of the pull wire 20 moves with the unlocking operating member 10, and the wire sleeve 202 does not move with the unlocking operating member 10.

[0077] When the pull wire 20 is partially arranged in the buffer zone, the section of the pull wire 20 located in the buffer zone includes the pull core wire 201 section and the wire sleeve 202 section. When external factors act on the pull wire 20, the pull wire 20 as a whole moves in the buffer zone and automatically adapts to the length change of the connecting belt 40, so that the pull core wire 201 and the wire sleeve 202 will not move relative to each other, thereby avoiding the pulling interlocking member 312 from moving relative to the female buckle seat 311, thereby avoiding accidental unlocking under the action of external factors. Only when the unlocking operating member 10 moves, can the pull core wire 201 be driven to move relative to the wire sleeve 202, thereby driving the interlocking member 312 to move relative to the female buckle seat 311, thereby achieving unlocking.

[0078] Furthermore, the lock release operating member 10 is rotatably connected to the lock housing 50. A protruding shaft portion 51 is provided inside the lock housing 50, and the first end 101 of the lock release operating member 10 is sleeved on the shaft portion 51 and can rotate around the shaft portion 51.

[0079] In order to realize the automatic reset of the lock release operating member 10, an elastic member 60 is provided between the lock release operating member 10 and the lock housing 50 to drive the lock release operating member 10 to reset. When the user operates the lock release operating member 10 to rotate, the elastic member 60 is elastically deformed, so that it has a tendency to reset. When the external force is removed, the lock release operating member 10 can be reset to the default position under the elastic force of the elastic member 60. In this embodiment, the elastic member 60 is a spring, one end of which is sleeved on the second end 102 of the lock release operating member 10, and the other end is sleeved on the convex column portion 52 provided in the lock housing 50.

[0080] The first end 2011 of the pull core wire 201 is connected to a portion of the unlocking operating member 10 other than the rotation center. In this embodiment, the first end 2011 of the pull core wire 201 is connected to a non-end portion of the unlocking operating member 10. In this way, when the unlocking operating member 10 rotates, the pull core wire 201 can be pulled to drive the linkage member to unlock.

[0081] In order to facilitate user operation, an operation area 53 in the form of a through hole is provided on the lock housing 50 . The second end 102 of the lock release operating member 10 extends out of the operation area 53 .

[0082] Furthermore, in order to facilitate the user's handheld operation, a grip hole area 54 in the shape of a through hole adjacent to the operating area 53 is further provided on the lock housing 50 .

[0083] Furthermore, the shaft portion 51 is located inside the winding portion 23 . To facilitate winding of the pull wire 20 , a wire hole 11 is provided on the unlocking operating member 10 . Part of the winding portion 23 passes through the wire hole 11 and is annularly located outside the shaft portion 51 .

[0084] In order to restrict the movement of the pull wire 20 in the buffer zone, a first stopper 55 and a second stopper 56 are provided inside the lock housing 50. The first stopper 55 and the second stopper 56 are spaced apart from each other to form a stopper groove 57, and the winding portion 23 of the pull wire 20 is at least partially located in the stopper groove 57, which can facilitate the winding and movement of the pull wire 20 without tangling.

[0085] The pull wire 20 is usually in a ring shape when wound. Therefore, in order to adapt to the winding activity of the pull wire 20, the limiting groove 57 is a circular groove or a part of a circular groove.

[0086] For the convenience of processing and installation, the lock housing 50 is formed by the first housing 501 and the second housing 502. The first housing 501 and the second housing 502 are matched to form a cavity. The buffer zone is arranged in the cavity.

[0087] A portion of the pull wire 20 is wound in the buffer zone and passes through the lock housing 50 , then enters the interior of the connecting belt 40 from the first end 41 of the connecting belt 40 , and then passes through the second end 42 of the connecting belt 40 to be connected to the interlocking assembly 30 .

[0088] Furthermore, the interlocking assembly 30 further includes a male buckle 32. The male buckle 32 and the female buckle 31 can be inserted into each other along the connection direction Y, thereby establishing a connection and connecting together.

[0089] When the unlocking operating member 10 drives the pulling core wire 201 to pull the interlocking member 312 , the female buckle 31 and the male buckle 32 are disengaged and can be separated.

[0090] To achieve the engagement, the male buckle 32 is provided with a protruding locking tongue 321. The locking tongue 321 is provided with a locking groove 3211, which is used to establish engagement with the interlocking member 312. When the male buckle 32 and the female buckle 31 are inserted into each other along the connection direction Y, the locking tongue 321 can engage with the interlocking member 312 to connect the male buckle 32 and the female buckle 31 together. When the unlocking operating member 10 is activated, the interlocking member 312 can be driven to move by the pulling core wire 201 to disengage the interlocking member 312 from the locking tongue 321, so that the male buckle 32 can be separated from the female buckle 31.

[0091] In order to assist the male buckle 32 and the female buckle 31 to quickly plug and establish a connection, a first magnet 313 is fixedly provided in the female buckle seat 311, and a second magnet 322 is provided in the lock tongue 321. The first magnet 313 and the second magnet 322 attract each other along the connection direction Y.

[0092] Furthermore, in order to facilitate the movement of the interlocking member 312 for locking and releasing, a locking hole 3111 and a sliding groove 3112 are provided on the female buckle seat 311 .

[0093] The lock hole 3111 is a through hole of constant size for inserting the lock tongue 321. The position of the lock hole 3111 corresponds to the first magnet 313, so that when the lock tongue 321 is inserted along the lock hole 3111, the first magnet 313 and the second magnet 322 are aligned and attract each other.

[0094] The slide groove 3112 is used to slide the interlocking member 312 to constrain the moving path of the interlocking member 312. The slide groove 3112 is located radially outside the lock hole 3111 and is connected to the lock hole 3111. The number of the slide grooves 3112 is not limited. In this embodiment, a total of two slide grooves 3112 are provided, which are symmetrically distributed, symmetrically distributed relative to the pulling direction X, and inclined relative to the pulling direction X. In other embodiments, the slide groove 3112 can also be set along the pulling direction X, or in a direction perpendicular to the pulling direction X.

[0095] The interlocking member 312 includes a linkage portion 3121 and a locking portion 3122 that are separately arranged. In other words, the linkage portion 3121 and the locking portion 3122 are two relatively independent components.

[0096] The linkage part 3121 is movably disposed in the female buckle seat 311 and is connected to the second end 2012 of the pull core wire 201. When the lock release operating member 10 moves, the linkage part 3121 can be directly pulled by the pull core wire 201 to move.

[0097] The locking portion 3122 is movably disposed in the slide groove 3112, and can move linearly along the slide groove 3112. From the connection direction Y, the locking portion 3122 is located between the linkage portion 3121 and the female buckle seat 311. When the locking portion 3122 moves along the slide groove 3112 and partially extends into the lock hole 3111, the locking portion 3122 is inserted into the lock groove 3211 of the lock tongue 321 in a direction transverse to the axial direction of the lock tongue 321, thereby engaging with the lock tongue 321. At this time, the lock tongue 321 cannot withdraw from the lock hole 3111, and the female buckle 31 is connected to the female buckle 31 together. When the locking portion 3122 moves in a direction away from the locking hole 3111, the end of the locking portion 3122 withdraws from the locking groove 3211 of the locking tongue 321, the locking portion 3122 disengages from the locking tongue 321, and the locking tongue 321 can withdraw from the locking hole 3111. At this time, the male buckle 32 can be separated from the female buckle 31.

[0098] To achieve locking, a third magnet 314 is provided in the locking portion 3122. The third magnet 314 interacts with the first magnet 313 to place the locking portion 3122 in a position, which may be an engagement position or a non-engagement position. When the lock tongue 321 is inserted along the lock hole 3111, the second magnet 322 in the lock tongue 321 interacts with the third magnet 314 to drive the locking portion 3122 to move, and finally moves to engage with the lock tongue 321.

[0099] When the second magnet 322 interacts with the third magnet 314, since the third magnet 314 is not directly opposite to the second magnet 322 but is located on one side of the axial direction of the second magnet 322, the magnetic properties between the third magnet 314 and the second magnet 322 will change with the insertion degree of the lock tongue 321. At the beginning, the third magnet 314 and the second magnet 322 repel each other, so that the locking portion 3122 moves in a direction away from the lock hole 3111, or remains at a position away from the lock hole 3111; when the lock tongue 321 enters the lock hole 3111, the third magnet 314 and the second magnet 322 attract each other, so that the locking portion 3122 moves in the direction of the lock hole 3111 and is laterally inserted into the lock groove 3211 of the lock tongue 321, so that the locking portion 3122 and the lock tongue 321 are engaged.

[0100] In order to release the lock, a protruding pushed portion 31221 is provided at the top of the locking portion 3122 facing the linkage portion 3121, and a protruding pushing portion 31211 is provided at the bottom of the linkage portion 3121 facing the locking portion 3122. The pushing portion 31211 abuts against the locking portion 3122, and the pushing portion 31211 is located at a side of the pushed portion 31221 close to the lock hole 3111. In other words, when viewed along the pulling direction X, the pushing portion 31211 is located between the lock hole 3111 and the pushed portion 31221.

[0101] When the linkage portion 3121 is pulled by the pull core wire 201 , the pushing portion 31211 pushes the pushed portion 31221 to drive the locking portion 3122 to move in the slide groove 3112 in a direction away from the lock hole 3111 , thereby disengaging the locking portion 3122 from the lock tongue 321 .

[0102] For convenient use, the female buckle 31 further includes a pull ring 315 rotatably connected to the female buckle seat 311. The pull ring 315 is rotatably connected to the female buckle seat 311, which can facilitate the rotation of the male buckle 32 and the female buckle 31 connected together to automatically adapt to the use angle.

[0103] In order to realize the rotation of the female buckle seat 311 and the pull ring 315, a rotating shaft column 3113 extending along the pulling direction X is provided on the female buckle seat 311. The rotating shaft column 3113 is fixedly connected or integrally formed with the female buckle seat 311. The pull ring 315 is annular and has a rotating shaft hole. The pull ring 315 is sleeved on the rotating shaft column 3113 through the rotating shaft hole to form a rotating connection. The pull ring 315 can rotate around the rotating shaft column 3113.

[0104] Furthermore, in order to prevent the pull ring 315 from being detached from the shaft column 3113, an annular groove is provided on the shaft column 3113, and a ring pin 316 is installed in the groove. The ring pin 316 abuts against the pull ring 315 to play an axial limiting role.

[0105] Furthermore, the second end 42 of the connecting belt 40 is sleeved on the pull ring 315. The second end 2022 of the wire sleeve 202 is fixedly connected to the pull ring 315, and the second end 2012 of the pull core wire 201 moves along the rotation center of the pull ring 315 through the pull ring 315 and is connected to the linkage part 3121 of the interlocking member 312.

[0106] More specifically, the second end 2022 of the wire sleeve 202 is fixed on the pull ring 315 and is spaced apart from the shaft column 3113. The second end 2012 of the pull core wire 201 passes through the pull ring 315, and extends through the shaft column 3113 to the female buckle seat 311 and is connected to the linkage portion 3121. In order to facilitate the arrangement of the pull core wire 201, a wire groove 3114 extending along its axial direction is provided on the shaft column 3113, and the wire groove 3114 extends from the end surface of the shaft column 3113 to the female buckle seat 311. After the second end 2012 of the pull core wire 201 extends from the second end 2022 of the wire sleeve 202, it passes through the hollow interior of the pull ring 315 and enters the wire groove 3114, and is led out from the wire groove 3114 to the female buckle seat 311 and is connected to the linkage portion 3121. In this way, when the unlocking operating member 10 moves, the pull core wire 201 can move relative to the wire sleeve 202, the pull ring 315, and the female buckle seat 311, thereby driving the linkage part 3121 to move along the pulling direction X relative to the female buckle seat 311, and then driving the locking part 3122 to move in a direction away from the lock tongue 321 to release the lock.

[0107] The connection between the second end 2012 of the core wire 201 and the linkage portion 3121 may be a fixed connection or a detachable connection, as long as the two can establish a connection and move together.

[0108] Furthermore, the connecting belt 40 is a double-layered webbing, and the two side edges along the width thereof are sewn together respectively, so as to form a sandwich space inside the connecting belt 40 for the pull wire 20 to pass through.

[0109] In order to facilitate the connection between the lock housing 50 and the connecting belt 40 , a mounting portion 58 is provided on the lock housing 50 . The mounting portion 58 is provided with a webbing hole, and the connecting belt 40 is sleeved on the mounting portion 58 .

[0110] During normal use, the release operating member 10 is pressed, and the release operating member 10 rotates, driving the pull core wire 201 to move relative to the wire sleeve 202, thereby pulling the linkage part 3121 of the interlocking member 312 to move along the pulling direction X. When the linkage part 3121 moves, it pushes the locking part 3122 to move, so that the locking part 3122 is disengaged from the lock tongue 321, and the male buckle 32 and the female buckle 31 can be separated, thereby realizing the release of the interlocking assembly 30.

[0111] When other external factors act on the pull wire 20, for example, when the connecting belt 40 extends, since the pull wire 20 can move in the buffer zone, it can provide a certain travel margin. Therefore, the pull wire 20 moves as a whole to adapt to the changes of the connecting belt 40, thereby offsetting the movement of the pull wire caused by external factors. At this time, the pull wire 20 will not pull the interlocking part 312, and the male buckle 32 and the female buckle 31 will not be released, thereby avoiding accidental release of the interlocking assembly 30 and further improving safety.

[0112] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
