Description

Technical Field

[0001] The present invention relates to the technical field of lock structures, and in particular to a zipper lock. Background Art

[0002] Currently, zipper locks are widely used in luggage. However, some zipper locks are prone to jamming during the unlocking process, and their unlocking reliability will be greatly reduced as the usage time increases.

[0003] For example, in the application number 201310038593.6, a zipper combination lock includes a lock housing, a lock core mechanism and a lock hook mechanism installed in the lock housing. The lock housing is provided with a lock core accommodating cavity for positioning and assembling the lock core mechanism and a lock hook accommodating cavity for positioning and assembling the lock hook mechanism. The lock core mechanism includes a combination wheel lock mechanism, which includes a slide plate and a plurality of combination wheel assemblies. The combination wheel assemblies include a combination wheel and an inner wheel connected in a rotational linkage. The slide plate cooperates with the inner wheel of each combination wheel assembly. The lock hook mechanism includes a lock hook body and an unlocking member, and the slide plate is linked to the unlocking member. The slide plate and the connecting rod are linked via a rotating block, thereby realizing the linkage between the combination wheel lock mechanism and the lock hook mechanism, and forming the combination wheel lock mechanism to unlock and lock the lock hook mechanism.

[0004] During the unlocking process, when the password is entered correctly, the slide plate is driven to move by the spring, so that the locking protrusion on the slide plate is inserted into the unlocking groove of the corresponding inner wheel, and the toggle block toggle the rotating block to rotate, so that the spacing cavity between the first linkage finger and the second linkage finger on the rotating block corresponds to the position of the connecting rod of the unlocking piece, and the connecting rod of the unlocking piece can be pushed into the spacing cavity, so that the lock hook body is pushed away from the lock hole to unlock the zipper combination lock.

[0005] However, when the slide plate is subjected to greater resistance or friction, or when the elastic force of the spring is weakened and cannot provide sufficient unlocking elastic force, the slider will not be able to move to the unlocking position, resulting in a phenomenon that the lock cannot be unlocked. Therefore, it is necessary to provide a zipper lock that is more reliable to use. Summary of the Invention

[0006] In order to overcome at least one of the defects of the prior art described above, the present invention provides a zipper lock to improve the problem of unreliable unlocking of the existing zipper lock, and has the advantages of high reliability and long service life.

[0007] The technical solution adopted by the present invention to solve the problem is:

[0008] According to one aspect of the present invention, there is provided a zipper lock, comprising: a lock housing; a combination lock mechanism and a lock hook mechanism disposed within the lock housing; wherein the combination lock mechanism comprises a movable plate and a plurality of combination wheel assemblies; the lock hook mechanism comprises a lock hook body that is pushed and capable of being locked with a zipper piece; a clutch member is disposed between the lock hook body and the movable plate.

[0009] When the zipper lock is in a locked state, the password wheel assembly can prevent the movable plate from moving, and the movable plate can prevent the lock hook body from moving through the clutch, thereby preventing the pusher from moving.

[0010] When the zipper lock is in the unlocked state, the code wheel assembly releases the blockage on the movement of the movable plate, and the movable plate can release the blockage on the movement of the lock hook body through the clutch, and then release the blockage on the push system. By pressing the push system, the push system can push the lock hook body to the unlocked position to push the clutch to move, and then push the movable plate to the unlocked position, and finally unlock the zipper chain. When unlocking, the present invention pushes the lock hook body, the clutch and the movable plate to the unlocked position by pressing the push system. Compared with the prior art that pushes the movable plate to the unlocked position by a spring, the present invention effectively avoids the movable plate from not moving to the unlocked position due to the large sliding friction of the movable plate or the insufficient elasticity of the spring, which in turn causes the unlocking failure. The unlocking process of the present invention is more reliable and stable.

[0011] The zipper chain of the present invention has a code wheel assembly comprising a code wheel and a code adjustment wheel which are connected in a rotational linkage; the lock hook mechanism comprises an unlocking piece which is integrally formed with the lock hook body; and a clutch piece is located between the unlocking piece and the movable plate.

[0012] An unlocking slot is provided on the coding wheel, and an unlocking protrusion capable of being inserted into the unlocking slot is provided on the movable plate.

[0013] When the unlocking groove is staggered with the unlocking protrusion, the movable plate will be prevented from moving. At this time, the zipper lock is in a locked state. At this time, the movable plate prevents the movement of the unlocking member through the clutch; by adjusting the digital password of the combination wheel to be correct and driving the coding wheel to rotate, the unlocking grooves on each coding wheel are aligned with the corresponding unlocking protrusions. At this time, the blockage of the movable plate's movement is released, and then the blockage of the unlocking member's movement is released through the clutch, so that the combination lock is in an unlockable state; pressing the push control, the push control pushes the unlocking member to slide, and then pushes the movable plate to move through the clutch, so that the unlocking protrusion is plugged into the unlocking groove, and the lock hook body can be unlocked as the unlocking member slides, and the unlocking process is stable and reliable.

[0014] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0015] The use of this zipper lock avoids unlocking failures caused by increased resistance of the movable plate after component wear. The unlocking process is stable and reliable, and the service life of the zipper lock is long. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Example

[0032] See Figures 1 to 10 The present invention discloses a zipper lock, comprising: a lock shell 1; a combination lock mechanism 2 and a lock hook mechanism 3 arranged in the lock shell 1; an installation cavity (not marked in the figure) is provided in the lock shell 1 for accommodating the combination lock mechanism 2 and the lock hook mechanism 3.

[0033] The combination lock mechanism 2 includes a movable plate 21 and several combination wheel assemblies 22. The combination wheel assembly 22 includes a combination wheel 221 and a code adjustment wheel 222 that are connected in a rotating linkage. The movable plate 21 cooperates with the code adjustment wheel 222 of each combination wheel assembly 22. The lock hook mechanism 3 includes a pusher 321, a lock hook body 31 and an unlocking member 32 integrally formed with the lock hook body 31. A clutch member 11 is provided between the movable plate 21 and the unlocking member 32.

[0034] In this application, three groups of code wheels 221 are provided, and the code wheel assemblies 22 are arranged in parallel along a straight line. An unlocking slot 2221 is provided on the code adjustment wheel 222, and an unlocking protrusion 211 that can be inserted into the unlocking slot 2221 is provided on the movable plate 21.

[0035] When the combination lock mechanism 2 is in an unlockable state, the unlocking grooves 2221 on the code wheel 222 are offset from the corresponding unlocking protrusions 211, preventing the movable plate 21 from moving. The movable plate 21 can then block the movement of the unlocking member 32 via the clutch 11, thereby preventing the movement of the lock hook body 31. When the digital passwords of all the combination wheels 221 are correct, the unlocking grooves 2221 on each code wheel 222 are aligned with the corresponding unlocking protrusions 211, allowing the unlocking protrusions 211 to insert into the unlocking grooves 2221, i.e., the movable plate 21 can move. At this point, the combination lock mechanism 2 is in an unlockable state. The specific unlocking process is as follows: pressing the pusher 321, which pushes the unlocking member 32 to move the clutch 11, thereby pushing the movable plate 21 to the unlocking position, allowing the unlocking protrusions 211 to insert into the unlocking grooves 2221, thereby achieving unlocking.

[0036] The unlocking member 32 is linearly slidably disposed in the lock housing 1 , and the unlocking member 32 drives the lock hook body 31 to slide to unlock in the same direction as the unlocking protrusion 211 is inserted into the unlocking slot 2221 .

[0037] When the lock mechanism is unlocked, the push member 321 is pressed against the locking member 321 and the locking member 32 is released, thereby preventing the lock mechanism from being unlocked due to the increase of frictional resistance of the components (such as the movable plate 21) after a long time or the failure of the spring force when a spring is used.

[0038] See Figure 5 A first resetting elastic member 4 is provided in the lock housing 1 and is connected to the movable plate 21 for applying an elastic force to the movable plate 21 . The direction of the elastic force is opposite to the direction in which the unlocking protrusion 211 is inserted into the unlocking groove 2221 .

[0039] The first reset elastic member 4 serves as an auxiliary member for resetting the movable plate 21. When the pressure of the push member 321 is removed or the push member 321 does not apply a thrust, the first reset elastic member 4 applies an elastic force to the movable plate 21, causing it to move in the opposite direction of the direction in which the unlocking protrusion 211 is inserted into the unlocking groove 2221, that is, the unlocking protrusion 211 is disengaged from the unlocking groove 2221, thereby facilitating the automatic locking process.

[0040] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 The pusher 321 is linked to the unlocking member 32 , and the pusher 321 protrudes out of the lock housing 1 .

[0041] By setting the pusher 321, during the unlocking process, the pusher 321 is pushed from the outside of the lock shell 1 to the inside of the lock shell 1, thereby driving the unlocking member 32, the lock hook body 31, the clutch member 11 and the movable plate 21 to move, thereby realizing the unlocking process.

[0042] In some possible implementations, the push member 321 is integrally formed with the unlocking member 32 .

[0043] In some more preferred implementations, the push member 321 and the unlocking member 32 are separately provided, which can reduce the difficulty of processing and also facilitate the positioning and installation of the push member 321 and the unlocking member 32.

[0044] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 A code adjustment switch 5 is provided in the lock housing 1. The code adjustment switch 5 includes a code adjustment plate 51 provided below the movable plate 21 and a code adjustment protrusion 52 connected to the code adjustment plate 51. A through hole 1023 is provided on the lock housing 1. The through hole 1023 can push the code adjustment protrusion 52 to slide and realize code adjustment.

[0045] See Figure 5 、 Figure 6 A rotating block 6 is also rotatably provided in the lock housing 1 , and two opposite toggle arms 61 are provided on the rotating block 6 , one toggle arm 61 can abut against the code adjustment protrusion 52 , and the other toggle arm 61 can abut against the push system 321 .

[0046] See Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 When setting the code, the code adjustment protrusion 52 is pushed from the outside of the lock shell 1 to the inside through the through hole 1023, so that the code adjustment protrusion 52 drives the code adjustment plate 51 to move, and then the code is adjusted. By setting the rotating block 6, after the code adjustment is completed, the pusher 321 is pressed into the lock shell 1, so that the pusher 321 presses one of the toggle arms 61, and the other toggle arm 61 swings in the opposite direction to push the code adjustment protrusion 52 to move outside the lock shell 1, so that the code adjustment pushes the code adjustment switch 5 to move to realize automatic resetting of the code adjustment switch 5.

[0047] See Figure 8A code adjustment positioning groove 511 for accommodating the code adjustment wheel 222 is provided on the code adjustment plate 51, and a separation elastic member 7 is provided between the code adjustment wheel 222 and the code wheel 221. The separation elastic member 7 applies an elastic force to the code adjustment wheel 222 away from the code wheel 221.

[0048] When the code adjustment protrusion 52 is pushed against the code adjustment plate 51 and the code adjustment positioning groove 511 is located below the code adjustment wheel 222, the separation elastic member 7 separates the code adjustment wheel 222, so that the code adjustment wheel 222 is located in the code adjustment positioning groove 511. At this time, the code adjustment wheel 221 will not drive the code adjustment wheel 222 to rotate, so as to perform the code resetting process; after the password is set, the code adjustment plate 51 moves to push the code adjustment wheel 222 out of the code adjustment positioning groove 511, and then the code adjustment wheel 222 is combined with the code wheel 221, and the linkage between the code wheel 221 and the code adjustment wheel 222 is restored.

[0049] Furthermore, the longitudinal cross-section of the code adjustment positioning groove 511 is tapered, which facilitates rapid positioning of the code adjustment wheel 222 and facilitates moving the code adjustment plate 51 to push the code adjustment wheel 222 away from the code adjustment positioning groove 511 .

[0050] See Figure 8 Furthermore, a code adjustment positioning protrusion 512 is provided on the inner wall of the code adjustment positioning groove 511, and a matching groove (not shown in the figure) that matches the code adjustment positioning protrusion 512 is provided on the side wall of the code adjustment wheel 222. The code adjustment positioning protrusion 512 cooperates with the matching groove to position and fix the code adjustment wheel 222 in the code adjustment positioning groove 511, thereby avoiding position displacement of the code adjustment wheel 222 during the password setting process.

[0051] See Figure 3 Furthermore, in order to realize the linkage between the coding wheel 222 and the cipher wheel 221, on the facing surfaces of the coding wheel 222 and the cipher wheel 221, one of them is provided with an engaging tooth 8, and the other is provided with an engaging groove 9. The synchronous rotation between the cipher wheel 221 and the coding wheel 222 is realized through the cooperation of the engaging tooth 8 and the engaging groove 9.

[0052] For example, the meshing teeth 8 can be set on the code wheel 221, and the meshing grooves 9 can be set on the coding wheel 222; of course, the meshing teeth 8 can also be set on the coding wheel 222, and the meshing grooves 9 can be set on the code wheel 221; in addition, the meshing teeth 8 and the meshing grooves 9 can also be set alternately on the code wheel 221 and the coding wheel 222.

[0053] See Figure 5 、 Figure 6The lock shell 1 is also provided with a lock core 10, and the clutch 11 is located between the unlocking member 32 and the movable plate 21. The lock core 10 can drive the clutch 11 to swing so that the clutch 11 can be staggered with the movable plate 21, and the movable plate 21 can release the obstruction to the movement of the clutch 11, and the clutch 11 can release the obstruction to the movement of the lock hook body 31; press the push control 321, and the push control 321 can push the lock hook body 31 to the unlocking position, thereby realizing the unlocking of the pull chain.

[0054] In a possible embodiment, the clutch 11 is provided with an abutting top 12, and the movable plate 21 is provided with a locking block 212; when in the locked state, the abutting top 12 abuts the locking block 212 to limit the movement of the clutch 11; when the lock cylinder 10 is unlocked, the lock cylinder 10 drives the clutch 11 to swing, so that the abutting top 12 can be staggered with the locking block 212, thereby allowing the lock hook body 31 to move to the unlocked position.

[0055] As another unlocking method, a lock core 10 is also provided in the lock housing 1. When unlocking is performed by using a key in combination with the lock core 10, the lock core 10 rotates to drive the clutch 11 to swing, so that the top portion 12 can be offset from the locking block 212. As a result, the clutch 11 removes the movement obstacle of the unlocking member 32, thereby allowing the unlocking member 32 to slide freely to realize the unlocking process.

[0056] The arrangement of the clutch 11 enables free switching between two unlocking modes. When the clutch 11 is located between the unlocking member 32 and the movable plate 21, the clutch 11, the unlocking member 32, and the movable plate 21 form an unlocking portion. That is, when the combination lock mechanism 2 is in an unlockable state, making the movable plate 21 movable, the unlocking member 32 can push the movable plate 21 via the clutch 11, so that the unlocking protrusion 211 on the movable plate 21 is inserted into the unlocking groove 2221, thereby achieving the unlocking process. If the combination lock mechanism 2 is in an unlockable state, making the movable plate 21 locked, the unlocking member 32 cannot move due to the obstruction of the clutch 11 and the movable plate 21, which means that the zipper lock is in a locked state.

[0057] When the lock cylinder 10 needs to be unlocked, the lock cylinder 10 drives the clutch 11 to swing, so that the top portion 12 is offset from the locking block 212. At this time, the unlocking member 32 is no longer blocked by the clutch 11 and the movable plate 21, and can move freely, thereby realizing the unlocking process of the zipper lock using the lock cylinder 10 unlocking method.

[0058] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 9A slide column 13 is provided on one of the lock housing 1 and the clutch member 11, and a slide groove 131 for sliding the slide column 13 is provided on the other. The setting direction of the slide groove 131 is parallel to the sliding direction of the unlocking member 32.

[0059] When the movable plate 21 is in the unlocked free movable state, the unlocking member 32 can push the clutch member 11 to move along the sliding groove 131 to achieve the unlocking process.

[0060] For example, the slide post 13 is disposed on the clutch member 11 , and the lock housing 1 is provided with a sliding groove 131 for the slide post 13 to slide.

[0061] Of course, in other possible implementations, the slide post 13 may be provided on the lock housing 1 , while the slide groove 131 may be provided on the clutch member 11 .

[0062] Furthermore, the sliding column 13 is cylindrical. Of course, in other possible implementations, the sliding column 13 may also be hemispherical, conical, or truncated cone-shaped.

[0063] See Figure 5 、 Figure 6 、 Figure 9 、 Figure 10 The clutch 11 is also provided with a driving ear 111, a driving groove 1111 is provided on the driving ear 111, and a driving column 1001 is provided on the lock cylinder 10. The driving column 1001 can slide along the driving groove 1111, and the driving column 1001 can be driven to abut against the inner wall of the driving groove 1111 to drive the clutch 11 to swing back and forth, so that the abutting top 12 is staggered or abutted with the locking block 212.

[0064] When the lock core 10 is rotated, the lock core 10 drives the driving column 1001 thereon to rotate, and then the driving column 1001 presses against the inner wall of the driving groove 1111 in the driving groove 1111, causing the driving ear 111 to rotate at an angle, that is, the clutch member 11 can rotate at an angle with the sliding column 13 as the rotation axis.

[0065] Specifically, when the lock cylinder 10 is unlocked, the driving column 1001 can drive the clutch 11 to swing around the axis of its sliding column 13, so that the top portion 12 is offset from the locking block 212. At this time, the movable plate 21 can release the obstruction to the unlocking member 32, and the unlocking member 32 can push the clutch 11 to slide along the sliding groove 131. At the same time, the driving column 1001 slides in the driving groove 1111 and drives the lock hook body 31 to move to realize the unlocking process.

[0066] During the locking process achieved by the lock cylinder 10, the lock cylinder 10 rotates, driving the drive column 1001 to rotate, and then the drive column 1001 drives the clutch 11 to rotate via the drive ear 111, causing the clutch 11 to swing to a reset state. At this time, the locking block 212 abuts against the abutting top 12, thereby restoring the blocking state of the movable plate 21 on the unlocking member 32, that is, the locking process of the zipper lock through the lock cylinder 10 is achieved.

[0067] See Figure 10 The lock core 10 is further provided with a reset auxiliary plate 14 , which can abut against the outer side of the driving ear 111 to assist the clutch member 11 in rotating and swinging back to its original position.

[0068] The setting of the reset auxiliary plate 14 can provide additional driving force to the driving ear 111 during the process of the clutch 11 returning to its original position, thereby making the clutch 11 reset reliably and avoiding the phenomenon of incomplete reset or even stuck and unable to reset.

[0069] See Figure 5 At least two locking hook bodies 31 are provided, the unlocking members 32 are provided in one-to-one correspondence with the locking hook bodies 31 , and a second reset elastic member 15 is provided corresponding to each locking hook body 31 .

[0070] By such a configuration, the second reset member applies a locking elastic force to the lock hook body 31. Under the driving action of this elastic force, the lock hook body 31 can be driven to the locked position under normal conditions; during the unlocking process, by pushing the pusher 321, after overcoming the locking elastic force, the movement of the movable plate 21 is linked to achieve the unlocking of the lock hook body 31.

[0071] See Figure 3 、 Figure 4 Furthermore, the lock shell 1 includes a bottom shell 101 and a surface cover 102, the bottom shell 101 and the surface cover 102 form the above-mentioned installation cavity, and the bottom shell 101 is fixed to the use position of the zipper lock, such as the side of the zipper opening and closing position of the luggage, through a threaded connector.

[0072] The cover 102 is provided with a connecting groove 1021 for connecting the zipper tab of the zipper to the lock hook body 31 , and a connecting hole 1022 for the lock hole of the lock cylinder 10 to pass through. The through hole 1023 is provided on the cover 102 .

[0073] With the above solution, in the locked state: when the clutch member 11 is located between the unlocking member 32 and the movable plate 21, that is, when the abutting top 12 abuts against the locking block 212, the unlocking groove 2221 is staggered from the corresponding unlocking protrusion 211, so that the movable plate 21 is in the locked state, and the lock hook body 31 is in the locked position.

[0074] When using the password to unlock, by adjusting the password wheel 221, the password wheel 221 drives the adjusting wheel 222 to rotate, so that the unlocking groove 2221 on each adjusting wheel 222 is aligned with the corresponding unlocking protrusion 211. At this time, the password lock mechanism 2 is in an unlockable state. Then, the pusher 321 is pushed into the lock shell 1, and the pusher 321 pushes the unlocking member 32 and the lock hook body 31 to move. The clutch member 11 drives the movable plate 21 to move under the push of the unlocking member 32. At this time, the slide post 13 slides along the slide groove 131, and the driving column 1001 slides in the driving groove 1111 until the unlocking protrusion 211 is plugged into the corresponding unlocking groove 2221, and the lock hook body 31 moves to the unlocking position, thereby unlocking the zipper lock.

[0075] When using the lock cylinder 10 to unlock, the key that matches the lock cylinder 10 is inserted into the lock cylinder 10, the lock cylinder 10 is rotated, and then the driving ear 111 is toggled by the driving column 1001 on the lock cylinder 10 to drive the clutch 11 to swing, so that the top portion 12 is staggered with the locking block 212, thereby releasing the blocking effect of the movable plate 21 on the unlocking member 32 through the clutch 11. At this time, referring to the above, the pusher 321 is pushed into the lock shell 1, and the unlocking member 32 and the lock hook body 31 are pushed by the pusher 321 to move, the slide column 13 slides along the slide groove 131, the driving column 1001 slides in the driving groove 1111, and the lock hook body 31 moves to the unlocking position, thereby realizing the unlocking of the zipper lock.

[0076] After the pressure on the pusher 321 is released, the lock hook body 31 moves and resets under the elastic force of the second reset elastic member 15 , that is, drives the unlocking member 32 and the pusher 321 to reset.

[0077] During the reset process after the password unlocking method is adopted, the movable plate 21 is reset under the action of the first reset elastic member 4 , and the clutch member 11 is reset along with the movement of the movable plate 21 .

[0078] During the resetting process after the lock cylinder 10 is unlocked, after the lock hook body 31, the unlocking member 32 and the pusher 321 are reset, the lock cylinder 10 rotates, driving the drive column 1001 to rotate, and then the drive column 1001 drives the clutch member 11 to rotate via the driving ear 111, so that the top portion 12 abuts against the locking block 212 of the movable plate 21, thereby restoring the linkage between the movable plate 21 and the unlocking member 32, that is, restoring the blocking state of the movable plate 21 to the unlocking member 32.

[0079] In summary, the zipper lock provided by the present invention has the advantage of reliable unlocking, can avoid the increase of friction resistance of components after a long time or the unlocking difficulty caused by the failure of spring elastic force when a spring is used, and realizes the unlocking and locking functions of both the password lock and the lock core 10. It has various usage methods and is convenient and reliable to lock and unlock.
