Description

Technical Field

[0001] The present invention relates to the technical field of password locks, and particularly to an anti-malfunction code avoidance structure and a double-opening password lock. Background Art

[0002] In the existing zipper-type password lock, the movable plate inside is mainly driven to move, so that the movable plate drives the lock block to move into or out of the movable range of the lock hook to achieve the purpose of unlocking or locking. Among them, the password device of the password lock is used to drive the movable plate to move.

[0003] Generally, the password device in the existing password lock is generally composed of a password wheel and a code adjustment wheel. A separable synchronous connection structure is generally adopted between the password wheel and the code adjustment wheel, and the synchronous connection structure generally adopts a connection form in which a protrusion cooperates with a slot. When the protrusion on the password wheel is located in the slot of the code adjustment wheel, the password wheel and the code adjustment wheel are connected to form an integral structure. Rotating the password wheel can drive the code adjustment wheel to drive the movable plate to move. When the protrusion is separated from the slot, the password wheel and the code adjustment wheel are separated. At this time, the numbers on the password wheel can be adjusted again, and then the two are closed and connected to achieve the purpose of resetting the password. In this separable password device structure, since a separable connection structure with protrusions embedded is adopted between the two, this structure generally cannot withstand too much torque.

[0004] In some usage situations, for example, during the locking process, there may be a situation where the lock hook fails to return to the locked state normally. At this time, the lock block will be blocked and interfered by the lock hook and cannot move to one side of the lock hook to achieve the locking purpose. If the movable plate is forcibly driven by the password device to drive the lock block to move in the locking direction, the movable plate will be subjected to a large reaction force. In this case, the code adjustment wheel in the password device will easily be separated from or misaligned with the password wheel due to the large torque, and then a malfunction code problem will occur, that is, the existing password lock may have a malfunction code problem of the password device during the locking process because the lock hook fails to return to the locked state normally. Summary of the Invention

[0005] Aiming at the deficiencies existing in the prior art, one of the purposes of the present invention is to provide an anti-malfunction code avoidance structure to solve the following technical problems mentioned in the background art: when the lock hook in the existing password lock fails to return to the locked state normally during the locking process, if the movable plate is forcibly driven by the password device to drive the lock block to move in the locking direction, a malfunction code problem will easily occur.

[0006] The technical solution adopted by the present invention to solve its problems is:

[0007] An anti - garbled code avoidance structure includes a movable lock block and a movable plate capable of driving the movement of the lock block. The lock block has an unlocking position for unlocking the password lock and a locking position for locking the password lock. The lock block is connected to the movable plate. Among them, a chute is formed on the movable plate, the lock block has a sliding portion, and at least a part of the sliding portion is slidably disposed in the chute; an avoidance cavity is formed on the chute. When the lock block moves from the unlocking position to the locking position, the sliding portion moves in the avoidance cavity, and there is a gap between the sliding portion and the cavity wall of the avoidance cavity.

[0008] Further, during the process of the lock block moving from the unlocking position to the locking position, taking the groove wall of the chute close to the sliding portion as the first wall; an expanding wall is formed on the first wall, the expanding wall is arc - shaped, and the space enclosed by the expanding wall forms the avoidance cavity capable of accommodating the movement of the sliding portion. The avoidance cavity communicates with the cavity of the chute; taking the position where the sliding portion is located in the chute when the lock block is in the unlocking position as the first position, and taking the position where the sliding portion is located in the chute when the lock block is in the locking position as the second position, the avoidance cavity is located between the first position and the second position.

[0009] Further, the groove wall of the chute opposite to the first wall is the second wall, and the second wall is configured to be able to drive the sliding portion to move from the second position to the first position, so as to drive the lock block to move from the locking position to the unlocking position.

[0010] Further, the anti - garbled code avoidance structure further includes a driving member for driving the lock block to move from the unlocking position to the locking position, and the driving member is connected to the lock block.

[0011] Further, the driving member is a first spring. When the lock block is in the unlocking position, the first spring is in a compressed state; the included angle between the direction of the elastic force exerted by the first spring on the lock block and the sliding direction of the lock block moving relatively in the chute is greater than 0° and less than 90°.

[0012] Another object of the present invention is to disclose a double - opening password lock, which includes a lock hook, a lock body, a password device, a lock post and the anti - garbled code avoidance structure as described above; the password device is rotatably installed in the lock body and can drive the movement of the movable plate in the anti - garbled code avoidance structure; the lock post is disposed in the lock body, and the lock post is configured to be able to drive the lock block in the anti - garbled code avoidance structure out of the movement range of the lock hook when the key is inserted, or to be able to drive the lock block into the movement range of the lock hook when the key is inserted.

[0013] Furthermore, a locking head is provided on the locking block in the anti - garbled code avoidance structure, and the locking head is configured to be able to move into the movement range of the locking hook; when the password of the password device is correct, the second wall of the sliding groove in the anti - garbled code avoidance structure drives the sliding part in the locking block to move to the first position in the sliding groove, and the locking head is outside the movement range of the locking hook; when the password of the password device is incorrect, the sliding part is configured to be able to move to the second position in the sliding groove, and the locking head is within the movement range of the locking hook.

[0014] Furthermore, a toggle lever is provided on the locking post, and a stop head is provided on the movable plate. The stop head is within the movement range of the toggle lever; when the toggle lever drives the stop head to move, the sliding groove drives the locking block to move outside the movement range of the locking hook.

[0015] Furthermore, the sliding groove further has a third position, which is located on the side of the second position away from the first position; when the toggle lever drives the stop head to move, the sliding part is configured to be able to move at least from the second position to the third position, and the locking head can move outside the movement range of the locking hook.

[0016] Furthermore, the double - opening password lock further includes a second spring for applying an elastic force to the movable plate, and the second spring is arranged in the lock body; the elastic potential energy of the second spring is greater than the elastic potential energy of the first spring in the anti - garbled code avoidance structure; when the password of the password device is correct, the second spring applies a force to the movable plate to compress the first spring, and drives the locking block to move outside the movement range of the locking hook through the sliding groove; when the password of the password device is incorrect, the movable plate compresses the second spring, and the sliding part can at least move to the first position under the action of the first spring.

[0017] In summary, the double - opening password lock provided by the present invention has the following technical effects:

[0018] 1) In the anti - garbled code avoidance structure, by forming a movable avoidance cavity for accommodating the sliding part in the sliding groove of the movable plate, the movable plate will not be blocked by the locking block when being stuck by the locking hook, so that the password device will not be subject to a large resistance caused by the inability of the sliding part to move further, thus avoiding the problem of the password device being over - stressed and generating garbled codes;

[0019] 2) Designing the first spring can play the role of replacing the movable plate to push the locking block to achieve the purpose of self - locking, and can also improve the smoothness of the locking block moving into the movement range of the locking hook;

[0020] 3) By specifically designing an expanded wall on the first wall that is always separated from the sliding part, combined with the pushing effect of the first spring, during the locking operation, the purpose of avoiding the problem of scrambled codes on the password device is achieved, improving the usage stability of the anti-scrambled code avoidance structure;

[0021] 4) For this double-opening password lock, by adding a lock post in the lock body that can be inserted with a key and configuring it to drive the lock block to move outside the movement range of the lock hook when rotating. In this way, in case of emergency or special situations, without using the password device, simply rotate the lock post with the key. When the lock block moves outside the movement range of the lock hook, push the pusher to achieve the purpose of unlocking, which is convenient and fast. And normally, it can also be unlocked through the password device, increasing the unlocking operations of the password lock and improving the adaptability of the password lock;

[0022] 5) This double-opening password lock designs a lock block and a sliding groove that have a structural stacking characteristic in space and can be interlocked with each other, achieving the purpose of improving the compactness of the internal structure, so that this double-opening password lock can reduce the overall structural space. And only by designing the sliding groove and the lock block, the purpose of interlocking can be achieved, simplifying the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0039] Refer to Figures 1 to 4, the object of this embodiment is to disclose a structure for preventing garbled codes and avoiding interference, which includes a movable lock block 3 and a movable plate 2 capable of driving the lock block 3 to move. The lock block 3 has an unlocking position that makes the password lock in an unlocked state and a locking position that makes the password lock in a locked state. The lock block 3 is connected to the movable plate 2. Specifically, a sliding groove 4 is formed on the movable plate 2, and the lock block 3 has a sliding portion 31, and at least a part of the sliding portion 31 is slidably disposed in the sliding groove 4; an avoidance cavity 5 is formed on the sliding groove 4. When the lock block 3 moves from the unlocking position to the locking position, the sliding portion 31 moves in the avoidance cavity 5, and there is a gap between the sliding portion 31 and the cavity wall of the avoidance cavity 5. The gap is configured such that when the lock block 3 moves from the unlocking position to the locking position, the sliding portion 31 is always separated from the cavity wall of the avoidance cavity 5.

[0040] For the structure for preventing garbled codes and avoiding interference disclosed in this embodiment, by forming the avoidance cavity 5 on the sliding groove 4, the sliding portion 31 can move in the avoidance cavity 5 when the lock block 3 moves from the unlocking position to the locking position, and there is always a gap between the sliding portion 31 and the cavity wall of the avoidance cavity 5, that is, the sliding portion 31 and the cavity wall of the avoidance cavity 5 never come into contact. In this way, when the lock block 3 moves from the unlocking position to the locking position, no mutual acting force will be generated between the movable plate 2 and the sliding portion 31. In this way, during the locking operation, that is, when the password device is rotated to an incorrect state (i.e., the lock block 3 is pushed from the unlocking position to the locking position), even if the lock hook does not return to the in-place position (that is, when the lock hook does not return to the position in the locked state, at this time, since the cavity wall of the avoidance cavity 5 is always separated from the sliding portion 31, the movable plate 2 will not be blocked by the lock block 3 caught by the lock hook 1), the password device will not be subject to a large resistance caused by the sliding portion 31 being unable to move further, so as to avoid the problem of the password device being subject to excessive force and generating garbled codes. Thus, even when the lock hook 1 fails to return to the normal position, the password device can still normally push the movable plate 2 to the position in the locked state, so as to ensure that after the lock hook 1 returns to its place by itself later (usually during use, the vibration of the luggage can make the lock hook 1 automatically return to its place), the movable plate 2 can move to the position in the locked state. In this way, later, only by driving the sliding portion 31 can the lock block 3 be moved to the locking position, so as to achieve the purpose of locking.

[0041] Preferably, during the movement of the lock block 3 from the unlocked position to the locked position, the groove wall in the sliding groove 4 close to the sliding part 31 is the first wall 41; an expanded wall 411 is formed on the first wall 41, and the expanded wall 411 is arc-shaped. Specifically, the center of curvature of the expanded wall 411 is located on the side close to the cavity of the sliding groove 4, and the space enclosed by the expanded wall 411 forms an avoidance cavity 5 capable of accommodating the movement of the sliding part 31. The avoidance cavity 5 communicates with the cavity of the sliding groove 4. By forming the arc-shaped expanded wall 411 on the first wall, the space of the cavity of the sliding groove 4 can be expanded, that is, the avoidance cavity 5 is formed by expanding the cavity space, which is convenient for molding design and the structure is simple; the position where the sliding part 31 is located in the sliding groove 4 when the lock block 3 is in the unlocked position is the first position 9, and the position where the sliding part 31 is located in the sliding groove 4 when the lock block 3 is in the locked position is the second position 10; the avoidance cavity 5 is located between the first position 9 and the second position 10. During the movement of the lock block 3 from the unlocked position to the locked position, the sliding part 31 will move relative to the movable plate 2 in the avoidance cavity 5. Also, since the sliding part 31 does not contact the cavity wall of the avoidance cavity 5, in this way, the purpose that the sliding part 31 does not interfere with the movement of the movable plate 2 to the position in the locked state can be achieved, so as to avoid the problem of random codes in the password device during the locking process.

[0042] Specifically, the groove wall in the sliding groove 4 opposite to the first wall 41 is the second wall 42, and the second wall 42 is configured to be able to drive the sliding part 31 to move from the second position 10 to the first position 9, so as to drive the lock block 3 to move from the locked position to the unlocked position. Since there will be no interference problem between the lock block 3 and the lock hook 1 during the process of the lock block 3 running from the locked position to the unlocked position, in this way, only by using the pushing action of the second wall 42 in the sliding groove 4 on the sliding part 31, the purpose of pushing the lock block 3 from the locked position to the unlocked position can be achieved.

[0043] Specifically, the anti-random code avoidance structure further includes a driving member for driving the lock block 3 to move from the unlocked position to the locked position, and the driving member is connected to the lock block 3. By providing the driving member, the function of pushing the lock block 3 to lock is used to replace the movable plate 2. So that after the lock hook 1 returns to its original position by itself, the lock block 3 can move to the locked position by itself, so as to achieve the purpose of automatic locking.

[0044] Among them, preferably, in this embodiment, the driving member is the first spring 6. When the lock block 3 is in the unlocked position, the first spring 6 is in a compressed state; in this way, during the locking operation, the first spring 6 will apply an elastic force to the lock block 3 to drive the lock block 3 to move from the unlocked position to the locked position. Using the spring structure as the driving member can also achieve the purpose of automatically pushing the lock block 3 to run after the lock hook returns to its original position by itself. To achieve the purpose of automatic locking.

[0045] Specifically, the included angle between the moving direction of the lock block 3 and the moving direction of the lock hook 1 is greater than 0° and less than 180°, and the included angle between the direction of the elastic force exerted by the first spring 6 on the lock block 3 and the sliding direction of the relative movement of the lock block 3 in the sliding groove 4 is greater than 0° and less than 90°, preferably 45°. In this embodiment, the included angle between the moving direction of the lock block 3 and the moving direction of the lock hook 1 is 90°, and the distance between the first position 9 and the lock hook 1 is set to be greater than the distance between the second position 10 and the lock hook 1, that is, the sliding groove 4 is offset.

[0046] Since there is an included angle greater than 0° and less than 90° between the direction of the elastic force of the first spring 6 and the relative sliding direction of the lock block 3 in the sliding groove 4, in some certain situations (in this embodiment, when the movable plate 2 moves in the direction close to the lock hook 1, refer to Figure 9 ), since the sliding groove 4 is set to have an included angle with the moving direction of the movable plate 2, the second wall 42 of the sliding groove 4 can exert a force on the lock block 3 towards the first spring 6, so as to compress the first spring 6, thereby enabling the lock block 3 to move outside the movement range of the lock hook 1, that is, to achieve the purpose of moving towards the unlocking position. Correspondingly, in some other certain situations (in this embodiment, when the movable plate 2 moves in the direction away from the lock hook 1, refer to Figure 10 ), the first spring 6 releases elastic potential energy and pushes the lock block 3 to move inside and outside the movement range of the lock hook 1, thereby achieving the purpose of locking.

[0047] Moreover, in this embodiment, the first spring 6 is designed, and through the pushing action of the first spring 6 on the lock block 3, it can also improve the smoothness of the movement of the lock block 3 into the movement range of the lock hook 1.

[0048] In some cases, when using a password lock, it is often necessary to first adjust the password device in the password lock to the correct state before the password lock can be opened. However, in some relatively urgent situations, it will take a long time to unlock when all password devices are adjusted correctly; or in some special situations such as forgetting the password or misremembering the number, for a password lock that can only be unlocked through the password device, there will be a problem of difficult unlocking.

[0049] Therefore, referring to Figures 5 to 11 , another object of this embodiment is to disclose a double-opening password lock, which includes a lock hook 1, a lock body 7, a password device 8, a lock post 13, and the anti-disorder code avoidance structure as described above; the password device 8 is rotatably installed in the lock body 7 and can drive the movable plate 2 in the anti-disorder code avoidance structure to move; the lock post 13 is arranged in the lock body 7, and the lock post 13 is configured to drive the lock block 3 in the anti-disorder code avoidance structure to move outside the movement range of the lock hook 1 or drive the lock block 3 to move into the movement range of the lock hook 1 when the key is inserted.

[0050] The double-opening combination lock disclosed in this embodiment is provided with a lock cylinder 13 for inserting a key in the lock body 7, and is configured to drive the lock block 3 to move outside the movement range of the lock hook 1 when rotating. In this way, in emergency or special circumstances, there is no need to use a code generator, and only the lock cylinder 13 can be rotated by the key. When the lock block 3 moves outside the movement range of the lock hook 1, the pusher 15 can be pushed to achieve the purpose of unlocking, which is convenient and quick. Moreover, under normal circumstances, the unlocking operation can also be performed through the code generator, which increases the unlocking operation of the combination lock and improves the adaptability of the combination lock.

[0051] Among them, see Figure 6 and Figure 7 The cipher 8 is composed of a cipher wheel 81 and a code adjustment wheel 82.

[0052] Preferably, a locking head 32 is provided on the locking block 3 in the anti-garbled code avoidance structure, and the locking head 32 is configured to be able to move within the movement range of the lock hook 1; when the password of the code device 8 is correct, the second wall 42 of the slide groove 4 in the anti-garbled code avoidance structure drives the sliding part 31 in the lock block 3 to move to the first position 9 in the slide groove 4, and the locking head 32 is outside the movement range of the lock hook 1, so as to achieve the purpose of unlocking; when the password of the code device 8 is wrong, the sliding part 31 is configured to be able to move to the second position 10 in the slide groove 4, and the locking head 32 can be within the movement range of the lock hook 1, so as to achieve the purpose of locking.

[0053] In addition, the double-opening combination lock disclosed in the present embodiment is designed with a lock block 3 for limiting the movement range of the lock hook 1 between the movable plate 2 and the lock hook 1, and a slide groove 4 is formed in the movable plate 2, so that the movable plate 2 and the slide groove 4 can be linked with each other, so as to achieve the purpose of locking the lock hook 1 or releasing the movement of the lock hook 1. Only the slide groove 4 and the lock block 3 need to be designed to achieve the purpose of mutual linkage, thereby simplifying the structure; since the lock block 3 and the movable plate 2 are linked with each other through the slide groove 4, and the slide groove 4 is formed in the movable plate 2, the lock block 3 and the movable plate 2 can achieve the effect of structural stacking and mutual linkage in space. Compared with the traditional combination lock that adopts a connecting rod structure or a chain belt structure for linkage transmission, the double-opening combination lock can optimize its internal structure layout, improve the compactness of the internal structure of the double-opening combination lock, so as to achieve the purpose of reducing the overall structural space.

[0054] Preferably, see Figures 7 to 11 A toggle rod 131 is provided on the lock column 13, and a stopper 11 is provided on the movable plate 2, and the stopper 11 is located within the movable range of the toggle rod 131; when the toggle rod 131 drives the stopper 11 to move, the slide groove 4 drives the lock block 3 to move out of the movable range of the lock hook 1 to release the movement restriction of the lock hook 1, thereby achieving the purpose of unlocking the lock column 13.

[0055] Preferably, referring to Figure 2 and Figure 8 , the sliding groove 4 further has a third position 14, and the third position 14 is located on the side of the second position 10 away from the first position 9; when the toggle lever 131 drives the stopper 11 to move, the sliding portion 31 is configured to be able to move at least from the second position 10 to the third position 14, and the locking head 32 can move outside the movement range of the locking hook 1. (In this embodiment, when the sliding portion 31 is in the first position 9, the locking head 32 is in the first side portion of the locking hook 1, and when the sliding portion 31 is in the third position 14, the locking head 32 is in the second side portion of the locking hook 1). By adopting the form of extending the sliding groove to form the third position, the purpose of unlocking through the locking column 13 can be achieved, which has the effects of simple structural design and convenient production.

[0056] Specifically, the double-opening password lock further includes a second spring 12 for applying an elastic force to the movable plate 2, and the second spring 12 is arranged in the lock body 7; the elastic potential energy of the second spring 12 is greater than the elastic potential energy of the first spring 6 in the anti-disorder code avoidance structure; when the password of the password device 8 is correct, the second spring 12 applies a force to the movable plate 2 to compress the first spring 6, and drives the lock block 3 to move outside the movement range of the locking hook 1 through the sliding groove 4. Since the elastic potential energy of the second spring 12 is greater than the elastic potential energy of the first spring 6, this enables the movable plate 2 to automatically squeeze the first spring 6 to achieve the purpose of self-unlocking during the unlocking process; when the password of the password device 8 is incorrect, the password device 8 will push the movable plate 2 to make the movable plate 2 compress the second spring 12, and the sliding portion 31 can at least move to the first position 9 under the action of the first spring 6, so as to achieve the purpose of automatic locking.

[0057] In summary, the anti-disorder code avoidance structure and the double-opening password lock disclosed in this embodiment can bring the following beneficial effects:

[0058] 1) In the anti-disorder code avoidance structure, by forming a movable avoidance cavity for accommodating the sliding portion in the sliding groove of the movable plate, the movable plate will not be blocked by the lock block when being caught by the locking hook, and further the password device will not be subjected to a large resistance caused by the inability of the sliding portion to continue moving, so as to avoid the problem of disordered codes due to excessive force on the password device;

[0059] 2) Designing the first spring can play the role of replacing the movable plate to push the lock block to achieve the purpose of self-locking, and can also improve the smoothness of the lock block moving into the movement range of the locking hook;

[0060] 3) By designing an expanded wall on the first wall that is always separated from the sliding part, combined with the pushing action of the first spring, during the locking operation, the purpose of avoiding the problem of scrambled codes on the cipher lock is achieved, improving the usage stability of the anti-scrambled code avoidance structure;

[0061] 4) For this double-opening cipher lock, by adding a lock post in the lock body that can be inserted with a key and configuring it to drive the lock block to move outside the movement range of the lock hook when rotating. In this way, in case of emergency or special situation, without using the cipher lock, just rotate the lock post with the key. When the lock block moves outside the movement range of the lock hook, push the pusher to achieve the purpose of unlocking, which is convenient and fast. And under normal circumstances, it can also be unlocked through the cipher lock, increasing the unlocking operations of the cipher lock and improving the adaptability of the cipher lock;

[0062] 5) This double-opening cipher lock designs a lock block and a chute that have a structural stacking characteristic in space and can be interlocked with each other, achieving the purpose of improving the compactness of the internal structure, so that this double-opening cipher lock can reduce the overall structural space, and only by designing the chute and the lock block, the purpose of interlocking can be achieved, simplifying the structure.

[0063] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
