Description

Technical Field

[0001] The present invention relates to the technical field of luggage locks, and in particular to a firmly locked luggage lock. Background Art

[0002] With the need for people to travel for work, tourism, business trips, etc., various types of luggage have occupied an increasingly important position in people's lives. People often put some valuables and documents in luggage for easy carrying. Therefore, the safety and anti-theft of luggage are becoming more and more important to people, and luggage locks have become an indispensable component of luggage.

[0003] In the prior art, luggage locks include a locking assembly, comprising a first hook and a second hook, mounted on either side of the luggage, that interlock and lock. The luggage lock also includes an operating member (which can be a push button, knob, etc.), a locking mechanism, and a transmission member. The locking mechanism can be a combination lock, key cylinder, or NFC. The operating member's restriction is released only after the locking mechanism is unlocked with a password, the correct key is inserted, and the lock is turned, or a near-field electronic control sensor is triggered. The operating member then drives the first hook to rotate or slide via the transmission member, releasing the lock from the second hook and unlocking the luggage.

[0004] For example, the Chinese patent document with publication number CN207749937U discloses a luggage lock and luggage. The luggage lock includes: a housing, a drive device, a transmission device, a limit device, a pop-up device, a lock hook, a control device, and an auxiliary locking device. The control device controls the drive device to move the transmission device according to a Bluetooth unlocking signal or a fingerprint unlocking signal, so that the transmission device drives the limit device away from the lock hook until the limit device unlocks the locked hook. At this time, the pop-up device ejects the lock hook and limits the limit device. The auxiliary locking device is connected to the limit device and is compressed as the transmission device moves. When the lock hook is pressed down until the pop-up device unlocks the limit device, the auxiliary locking device pushes the limit device toward the lock hook until the limit device locks the lock hook. Because the luggage lock is opened by Bluetooth signals or fingerprint signals, the user does not need to remember the password. In addition, when the luggage lock is applied to a luggage, the user can open the luggage through Bluetooth signals or fingerprint signals, without having to remember the luggage password. This type of lock uses NFC near-field sensing to achieve unlocking.

[0005] Another example is the password lock disclosed in the Chinese patent document with publication number CN205012764U, which includes a central lock, a first side lock and a second side lock. The first side lock is arranged at both ends of the central lock, and the first side lock and the second side lock are controlled by a rotating block and a steel wire rope. The central lock controls the opening and closing of the first side lock and the second side lock through the central control transmission mechanism therein, wherein the central lock, the first lock buckle of the first side lock, and the second lock buckle of the second side lock are fixed to the frame of one opening and closing side of the box, and the first lock hook of the first side lock and the second lock hook of the second side lock are fixed to the frame of the other opening and closing side of the box.

[0006] As can be seen from the above, various luggage locks are inseparable from the locking components. Some have lock hooks that cooperate with zippers, and some have two sets of lock hooks that cooperate. For the structure with two sets of lock hooks, there are two existing technologies:

[0007] The first type is: the first lock hook is elastically and movably installed to maintain a positive rotation and engagement trend. When the bag is closed, the second lock hook is inserted, and the second lock hook pushes the first lock hook to make way in the opposite direction. After the second lock hook is inserted into place, the first lock hook is reset in the positive direction and engages to achieve locking; when unlocking, the transmission part forcibly drives the first lock hook in the opposite direction to stagger with the second lock hook to achieve unlocking; the first lock hook of this structure is kept locked by a spring, and the first lock hook must have room for movement. In the case of severe shaking (check-in process) or heavy falling or knocking, the first lock hook is easy to passively overcome the elastic force and move to unlock, resulting in insufficient safety performance.

[0008] The second type is: the forward locking and reverse unlocking movements of the first lock hook are both achieved by a push mechanism, that is, when the push mechanism is in the unlocking position, the first lock hook is in the unlocking state, and when the push mechanism is in the locking position, the first lock hook is in the locking state. The usage process is: manually operate the push mechanism to the unlocking position → the first lock hook is opened and in the unlocking posture → the two opening and closing sides of the bag are closed and the second lock hook is inserted → manually operate the push mechanism to the locking position and drive the first lock hook to achieve locking. There are problems: although the first lock hook of this structure is forcibly limited by the push mechanism and is not easily unlocked by external force after being successfully locked; however, when the push mechanism is in the unlocking position, after the two opening and closing sides of the bag are closed, the first lock hook will not automatically engage with the second lock hook. The user cannot confirm whether the two lock hooks are hooked, or when the bag is full of things and bulges, the two lock hooks are repelled and difficult to hook with each other. There is uncertainty that some or all of the lock hooks are not locked with each other, resulting in low safety performance, inconvenient operation, and poor user experience. Especially for the "one control, multiple opening" central control lock, that is, a luggage lock with a middle group of locking mechanisms controlling multiple locking components, such as the luggage lock disclosed in the prior art cited above, because the number of locking components is more than two, it is not easy for users to operate when in use, and it is even more difficult to observe whether the lock on the inside of the luggage is fastened. Therefore, the current luggage lock with such locking components is in urgent need of improvement. Summary of the Invention

[0009] In view of the above technical problems in the prior art, the present invention provides a luggage lock with a stable locking function.

[0010] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] A luggage lock with a stable locking function is provided, comprising a central control mechanism and a locking assembly A. The locking assembly A comprises a first locking hook and a second locking hook respectively mounted on the two opening and closing sides of the luggage, the first locking hook being capable of interlocking to lock and separating to unlock the luggage. The first locking hook is movably mounted on the lock housing, and is characterized in that: the first locking hook is provided with a first elastic member to ensure that the first locking hook maintains an unlocking tendency;

[0012] The lock housing is provided with a locking member, and the first lock hook is provided with a linkage portion, so that when the bag is closed, the second lock hook overcomes the force of the first elastic member and pushes against the linkage portion to drive the first lock hook to move, so that the first lock hook and the second lock hook are in mutual engagement, and the locking member moves to a locked state that restricts the rotation of the first lock hook;

[0013] The central control mechanism includes a password component and / or a key lock cylinder, as well as operating components controlled by the central control mechanism. Restrictions on the operating components can only be released after the central control mechanism inputs the correct instructions;

[0014] The lock housing is provided with an unlocking assembly, and the operating member is controlled to drive the unlocking assembly to drive the locking member to release the restriction on the first lock hook and unlock the lock.

[0015] Specifically, it also includes a locking component B, which includes a lock hook 1 and a lock hook 2 respectively installed on the two opening and closing sides of the bag. The two can be locked together and separated from each other, and the lock hook 1 elastically maintains the locking tendency; only after the central control mechanism inputs the correct instruction can the restriction on the operating part be released, and the operating part is controlled to drive the lock hook 1 to unlock.

[0016] Specifically, it also includes a lock body, the central control mechanism is installed on the lock body, and one of the locking component A and the locking component B is installed on the lock body, and the other is located outside the lock body.

[0017] Specifically, the locking member is movably mounted on the lock housing, and the locking member is provided with a second elastic member, which makes the locking member maintain a tendency to approach the first lock hook, so that after the first lock hook is pushed to the mutually engaged position by the second lock hook, the second elastic member drives the locking member to automatically limit the first lock hook.

[0018] Specifically, a limiting protrusion is provided on the side of the first locking hook. In the locked state, the locking member presses against the limiting protrusion to limit the movement of the first locking hook.

[0019] Specifically, the first lock hook and the locking member are both swingably mounted on the lock housing, and the first elastic member and the second elastic member are torsion springs.

[0020] Specifically, the unlocking assembly includes a shift block and an unlocking block. The unlocking block is slidably mounted on the lock housing, and the shift block is elastically and floatingly mounted on the unlocking block. When the unlocking block slides forward under external force, the shift block drives the locking member to release the restriction on the first lock hook. When the unlocking block is reset in the reverse direction, it floats to avoid the locking member.

[0021] Specifically, one end of the shift block is hinged to the lock housing, the shift block is provided with a third elastic member, which keeps the shift block close to the locking member, and the unlocking block is provided with a third blocking portion that limits the rotation range of the shift block.

[0022] Specifically, the shift block is provided with a hook, which includes a hook body and an inclined back. When the unlocking block slides forward under external force, the hook body drives the locking member; when the unlocking block is reset in the reverse direction, the locking member overcomes the force of the third elastic member and pushes against the inclined surface to make way.

[0023] Specifically, the unlocking assembly further includes a transmission member, which is connected to the unlocking block to drive the unlocking block to slide.

[0024] Beneficial effects of the present invention:

[0025] Compared to existing technologies, the present invention's securely locked luggage lock features a key innovation: a locking assembly A. When the luggage is closed, the second hook pushes against the first hook, automatically engaging it. Regardless of whether the unlocking assembly is in the unlocked or locked position, this ensures that the first and second hooks remain locked together when the luggage is closed, enhancing user experience. Furthermore, when the first and second hooks are locked together, the first hook is automatically locked by the locking member, eliminating the need for manual user intervention to lock the luggage, further enhancing safety.

[0041] The present invention is described in detail below with reference to specific embodiments and accompanying drawings.

[0042] A luggage lock of this embodiment is a firmly locked one, such as Figures 1 to 7 As shown, it includes a lock body 6, a central control mechanism 61 is provided in the middle of the lock body 6, and the central control mechanism 61 includes a password component 611 and a key lock cylinder 612. The lock body 6 is also provided with an operating member 62. The operating member 62 is a push-type device that can slide along the length of the lock body 6. A slide bar 63 is connected below the push-type device. The slide bar 63 is arranged to slide along the length of the lock body 6. The operating member 62 is restricted by the central control mechanism 61. After the password is entered in the password component 611 or the correct key is inserted and turned in the key lock cylinder 612, that is, the correct instruction is entered, the restriction on the operating member 62 can be released, and the operating member 62 and the slide bar 63 can be manually pushed. The above is a common structure of existing luggage locks, and the luggage lock in this example also includes this basic structure.

[0043] In this embodiment, four locking assemblies are provided at both ends of the lock body 6 and on the outside of the lock body 6. This type of lock is suitable for hard luggage. The two locking assemblies on the lock body 6 are located on one side of the luggage, and the two locking assemblies on the outside of the lock body are located on the other two sides of the luggage, locking the three sides of the luggage. The locking assembly located on the lock body is an improved locking assembly A7, and its specific structure is as follows:

[0044] The first lock hook 1 and the second lock hook 2 are respectively installed on the two opening and closing sides of the bag. The two can be locked together and separated. The first lock hook 1 is rotatably installed (swinging within a certain range) on the lock housing 3. The middle part of the first lock hook 1 is provided with a first elastic member (torsion spring) to keep the first lock hook 1 unlocking tendency, that is, Figure 4 Rotate counterclockwise.

[0045] The lock housing 3 is provided with a locking member 4, the middle portion of which is rotatably connected to the lock housing 3, and the locking member 4 is provided with a second elastic member (torsion spring), which keeps the locking member 4 close to the first lock hook 1, that is, Figure 4 The side of the first lock hook 1 is provided with a limiting protrusion 11, such as Figure 5 In the unlocked state, the end of the locking member 4 leaves the rotation track of the limiting protrusion 11, as shown in FIG. Figure 4 In the locked state, the locking member 4 presses against the limiting protrusion 11 to limit the rotation of the first locking hook 1 .

[0046] In this embodiment, the first lock hook 1 is provided with a linkage portion 12. When the luggage is closed, the second lock hook 2 overcomes the force of the first elastic member and pushes against the linkage portion 12, driving the first lock hook 1 to rotate. This causes the first and second lock hooks 1 and 2 to engage with each other, and the locking member 4 to follow the movement to a locked state that restricts the rotation of the first lock hook 1. Obviously, after the first lock hook 1 is pushed to the mutually engaged position by the second lock hook 2, the locking member 4 is driven by the second elastic member to automatically push against the limiting protrusion 11, restricting the reverse rotation of the first lock hook 1 and achieving locking. The linkage portion 12 is a raised structure integrally formed with the first lock hook 1. In practice, the linkage portion 12 can take other forms, as long as it can cooperate with the second lock hook 2 to drive the first lock hook 1 to engage with each other when the luggage is closed.

[0047] In this embodiment, the lock housing 3 is provided with a first blocking portion 31 for limiting the swinging range of the first lock hook 1 and a second blocking portion 32 for limiting the swinging range of the locking member 4, so that the first lock hook 1 and the locking member 4 can swing within a preset range.

[0048] In this embodiment, the lock housing 3 is provided with an unlocking assembly 5. When driven by an external force, the unlocking assembly 5 can drive the locking member to release the restriction on the first lock hook 1 and unlock the lock. Specifically, the unlocking assembly 5 includes a shifting block 51, an unlocking block 52, and a transmission member 53. The unlocking block 52 is slidably mounted on the lock housing 3. The transmission member 53 is connected to the unlocking block 52 to drive the unlocking block 52 to slide. The transmission member 53 is a steel cable, one end of which is connected to a slide bar 63 and the other end is connected to the unlocking block 52. When the operating member 62 and the slide bar 63 move, they can drive the unlocking block 52 to slide forward and reverse. The transmission disclosed in the literature cited in the background art is similar to that disclosed in detail here. One end of the shift block 51 is hinged to the lock housing 3. The shift block 51 is provided with a third elastic member (preferably a compression spring, which pushes the shift block 51 upward. It can also be a torsion spring installed on the hinge shaft). The third elastic member keeps the shift block 51 close to the locking member 4 and is elastically and floatingly installed on the unlocking block 52. The unlocking block 52 is provided with a third blocking portion 521 that limits the rotation range of the shift block 51. Under the interaction of the third elastic member and the third blocking portion 521, the shift block 51 is kept as Figure 2 The position shown. When the transmission member 53 and the unlocking block 52 slide forward due to an external force, the shifting block 51 drives the locking member 4 to rotate in the opposite direction, releasing the restraint on the first locking hook 1. When the unlocking block 52 resets in the opposite direction, it floats out of the way of the locking member 4. It can be seen that the unlocking assembly 5 in this example only enables one-way unlocking and has no effect on locking, thus achieving the effect of independent locking and unlocking. In practice, the unlocking assembly 5 can be modified to a similar one-way unlocking structure to achieve the basic purpose of locking even in the unlocked position.

[0049] Specifically, the shift block 51 is provided with a hook 511, which includes a hook body 5111 and a slanted back 5112. When the unlocking block 52 slides forward under external force, the hook body 5111 drives the locking member 4; when the unlocking block 52 is reset in the reverse direction, the locking member 4 overcomes the action of the third elastic member and pushes against the inclined surface to make way, and the inclined surface plays a good guiding role.

[0050] In this embodiment, the locking assembly located at both ends of the lock body 6 is defined as a locking assembly B8, which includes a lock hook 1 81 and a lock hook 2 82 respectively installed on the two opening and closing sides of the luggage. The two can be locked together and separated from each other. The middle part of the lock hook 1 81 is rotatably installed on the lock body 6. The lock body 6 is provided with a compression spring to apply force to the lock hook 1 81 so that the lock hook 1 81 elastically maintains the locking tendency. After the lock hook 2 82 is inserted, the lock hook 2 82 overcomes the elastic force and pushes the lock hook 1 81 away. After being locked in place, the lock hook 1 81 elastically resets; after the central control mechanism 61 inputs the correct instruction, the restriction on the operating member 62 is released, and the operating member 62 is controlled by the external force to drive the slide bar 63 to slide, thereby driving the lock hook 1 81 to rotate and unlock.

[0051] It should be noted that in this example of a luggage lock, the central control mechanism 61 includes both a password assembly 611 and a key lock cylinder 612. In practice, the lock can be modified to have only one of these unlocking methods. The operating member 62 in this example is a push-operated mechanism, but can actually be replaced with a button or knob. These are conventional technical alternatives in the luggage lock field and will not be discussed in detail here.

[0052] In this example, the innovative locking assembly A is located outside the lock body 6, while the ordinary locking assembly B is located on the lock body. In practice, the order of these positions can be reversed, for example, the improved locking assembly A can be changed to be located on the lock body, while the ordinary locking assembly B can be located outside the lock body. This example includes the improved locking assembly A and the ordinary locking assembly B. In practice, the improved locking assembly A can be used for all of them. This example shows a "one control, multiple openings" luggage lock in which a central control mechanism controls multiple locking assemblies. In practice, it can be changed to a "one control, one opening" or "one control, two openings" luggage lock. In short, as long as the luggage lock uses the improved locking assembly A, it is within the interpretation of the scope of protection of the claims.

[0053] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components.
