Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a luggage lock that is easy to operate. 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, which includes a lock hook and a lock catch, respectively installed on the two opening and closing sides of the luggage, which interlock and lock. Alternatively, the locking assembly locks the zipper. The luggage lock also includes an operating member (which can be replaced by a push button, knob, etc.), a locking mechanism, and a transmission member. The locking mechanism can be a combination lock, key lock cylinder, or NFC. The operating member's restriction can only be released after the locking mechanism is unlocked by the password, the correct key is inserted and turned, or a near-field electric control sensor is triggered. The operating member drives the lock hook to rotate or slide via the transmission member, releasing the lock from the lock catch or releasing the limit on the zipper to achieve unlocking.

[0004] Existing luggage locks all have operating parts, whether push-buttons, buttons, or knobs, which occupy a certain amount of space in the lock body and require a corresponding internal transmission mechanism to unlock. As the times change, consumers are increasingly seeking simpler and more innovative products, and traditional locks cannot meet this demand. Summary of the Invention

[0005] In view of all or part of the above-mentioned technical problems in the prior art, the present invention provides a luggage lock that is easy to operate.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Provided is a luggage lock that is easy to operate, comprising a lock body and a handle. The lock body comprises a lock shell, the lock shell being provided with a lock hole, a lock hook being movably provided in the lock shell and aligned with the lock hole, and a spring being provided in the lock shell for returning the lock hook to its original position after displacement.

[0008] The lock housing is also provided with a locking mechanism, which limits the position of the lock hook to achieve locking. Only when the correct instruction is input into the locking mechanism can the restriction on the lock hook be released to achieve unlocking. Its characteristics are:

[0009] The two ends of the handle are hinged to the lock shell. Under normal circumstances, the handle is placed horizontally and biased toward one side of the lock shell. External force swings the handle to an upright pulling state but fails to drive the lock hook. In the unlocked state, external force swings the handle to the other side of the lock shell and can drive the lock hook to move from the locked position to the unlocked position.

[0010] Specifically, the lock hook is slidably installed in the lock housing, and the handle can drive the lock hook to slide after rotating to a preset angle.

[0011] Specifically, a linkage block is slidably provided in the lock shell, and the linkage block and the lock hook are matched via an inclined surface so that the sliding direction of the linkage block is arranged perpendicular to the sliding direction of the lock hook. When the handle is turned to a preset angle, the linkage block is driven to slide, and then the lock hook is driven to slide in the vertical direction.

[0012] Specifically, the head of the handle is provided with a toggle protrusion, and the linkage block is provided with a receiving groove and a toggle groove that are connected to each other. The toggle protrusion is movably accommodated in the receiving groove. Only after the handle is rotated to a preset angle, the toggle protrusion is embedded in the toggle groove to drive the linkage block to move.

[0013] Specifically, the lock hook includes a rod body and a hook body. The rod body is slidably installed in the lock housing. The end of the rod body cooperates with the linkage block. The hook body is located in the middle of the rod body and is aligned with the lock hole.

[0014] Specifically, the locking mechanism includes a stop button, which is rotatably installed in the lock shell. A stop block is provided on the outside of the stop button. In the locked state, the stop block is aligned with the lock hook to limit its sliding; in the unlocked state, the stop block is offset from the lock hook to release its restriction.

[0015] Specifically, a first driving part is also provided on the outside of the stop button, and the locking mechanism includes a key assembly, and the key assembly includes a lock core and an unlocking block. The unlocking block is installed at the bottom of the lock core. After the lock core is inserted with the correct key and rotated, the unlocking block drives the first driving part to drive the stop button to rotate and unlock.

[0016] Specifically, a second driving part is further provided on the outer side of the stop button, and the locking mechanism further includes a password assembly, which includes a support, a plurality of password wheels and a plurality of coding wheels. The plurality of password wheels are rotatably mounted on the lock housing, and the plurality of coding wheels are mounted on the bottom of the plurality of password wheels in a one-to-one correspondence, and the coding wheels rotate together with the corresponding password wheels.

[0017] The support is slidably arranged below the coding wheel, and the support is provided with multiple give-way protrusions located beside the multiple coding wheels. The outer side of each coding wheel is respectively provided with a give-way groove. When each code wheel rotates to the correct code, each give-way protrusion is aligned and embedded in the give-way groove of the corresponding coding wheel, thereby causing the support to toggle the second driving part, driving the stop button to rotate and unlock.

[0018] Specifically, a code-changing seat is slidably provided under the support, and a code-changing slot is provided on the top of the code-changing seat. When an external force pushes the code-changing seat until the code-changing slot is aligned with the code-adjusting wheel, the code-adjusting wheel can separate from the code wheel and fall into the code-changing slot; after the code-changing seat is reset, the code-adjusting wheel resumes matching the code wheel.

[0019] Specifically, a limit seat is provided at the support. When the password is incorrect, the limit seat abuts to prevent the code-changing seat from moving; when the password is correct, the limit seat releases the restriction of the code-changing seat.

[0020] Beneficial effects of the present invention:

[0021] The present invention provides a convenient luggage lock. In the unlocked state, external force swinging the handle toward the other side of the lock housing can drive the lock hook from the locked position to the unlocked position. No additional operating components such as push knobs or twist knobs are required, making the entire lock body simple and novel. Furthermore, when the user operates the handle to unlock, they often grip the handle with their entire hand, which provides a larger force area and facilitates unlocking. Furthermore, the handle only engages the lock hook when rotated beyond a certain angle. Rotating the handle from a horizontal position to an upright position retains its original pulling function, creating a single, multi-purpose device and increasing the flexibility of the luggage lock.

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] The present embodiment is a luggage lock that is easy to operate, such as Figures 1 to 9 As shown, it includes a lock body 1 and a handle 2. The lock body 1 includes a lock shell 3. The lock shell 3 is provided with two lock holes 31. A lock hook 4 is movably provided in the lock shell 3 and aligned with the lock holes 31. A spring is also provided in the lock shell 3 to reset the lock hook 4 after displacement, that is, the lock hook 4 maintains a tendency to lock in the upward position, and the lock hook 4 can only be driven to slide by external force to overcome the action of the spring.

[0044] In this embodiment, the lock housing 3 is further provided with a locking mechanism 5, which limits the position of the lock hook 4 to achieve locking. Only when a correct instruction is input to the locking mechanism 5 can the restriction on the lock hook 4 be released to achieve unlocking. The locking mechanism 5 will be described in detail later.

[0045] The handle 2 is generally in a U - shape, with both ends hinged to the lock housing 3. Under normal conditions, the handle 2 is horizontally placed and biased towards one side of the lock housing 3. When an external force swings the handle 2 to the upright lifting state, the lock hook 4 cannot be driven. In the unlocking state where the locking mechanism 5 releases the restriction on the lock hook 4, and when an external force swings the handle 2 to the other side biased towards the lock housing 3, the lock hook 4 can be driven to move from the locked position to the unlocked position. Generally speaking, in the lifting state, the handle 2 turns to the vertically upright state. The handle 2 rotates about 90° from the horizontal position to the lifting state, and in this state, the lock hook 4 cannot be driven. In the locked state, the lock hook 4 also cannot be driven, but the lock hook 4 does not interfere with the rotation of the handle 2, enabling the handle 2 to retain its original basic lifting function. As long as the rotation amplitude of the handle 2 exceeds 90°, interference with the lock hook 4 will occur roughly within the range of 100° - 180°. After the locking mechanism 5 is unlocked and the limit on the lock hook 4 is released, the handle 2 can drive the lock hook 4 to move.

[0046] Specifically, the lock hook 4 includes a rod body 41 and a hook body 42. The rod body 41 is slidably installed in the lock housing 3. The hook body 42 is located in the middle of the rod body 41 and is arranged aligned with the lock hole 31 for hooking the zipper tab. Specifically, a linkage block 9 is slidably provided in the lock housing 3. The linkage block 9 and the rod body 41 of the lock hook 4 are in cooperation via an inclined plane, such that the sliding direction of the linkage block 9 is perpendicular to the sliding direction of the lock hook 4. After the handle 2 is turned to a preset angle, it drives the linkage block 9 to slide, and then drives the lock hook 4 to slide in the vertical direction. In this embodiment, the hook body 42 is integrally formed with the rod body 41. Of course, in practice, the shape of the lock hook 4 can be changed to other forms, as long as the rotation of the handle 2 can drive it to move and unlock. There is also a seat body between the end of the rod body and the linkage block 9 in the figure. Since this seat body moves together with the rod body, it can be understood and summarized as a part of the rod body.

[0047] Specifically, a拨动凸起21 is provided at the head of the handle 2. The linkage block 9 is provided with a through - accommodating groove 91 and a拨动槽92. The拨动凸起21 is movably accommodated in the accommodating groove 91, and only after the handle 2 is turned to the preset angle, the拨动凸起21 is inserted into the拨动槽92 to drive the linkage block 9 to move.

[0048] In this embodiment, the locking mechanism 5 includes a stop button 6. The stop button 6 is rotatably installed in the lock housing 3. A stop block 61 is provided on the outer side of the stop button 6. In the locked state, the stop block 61 is aligned and abuts against the lock hook 4 to restrict its sliding; in the unlocked state, the stop block 61 is错开 from the lock hook 4 to release its restriction. A torsion spring is provided at the stop button 6 to keep the stop button 6 in a tendency to limit the lock hook 4.

[0049] Specifically, a first driving part 62 is also provided on the outside of the stop button 6, and the locking mechanism 5 includes a key assembly 7. The key assembly 7 includes a lock core 71 and an unlocking block 72. The unlocking block 72 is installed at the bottom of the lock core 71. After the lock core 71 is inserted with the correct key and rotated, it drives the unlocking block 72 to move the first driving part 62 to drive the stop button 6 to rotate and unlock.

[0050] Specifically, a second driving portion 63 is further provided on the outer side of the stop button 6. The locking mechanism 5 also includes a password assembly 8, which includes a support 81, multiple password wheels 82, and multiple code adjustment wheels 83. The multiple password wheels 82 are rotatably mounted on the lock housing 3. The multiple code adjustment wheels 83 are mounted on the bottom of the multiple password wheels 82 in a one-to-one correspondence, and the code adjustment wheels 83 rotate together with the corresponding password wheels 82. The support 81 is slidably disposed below the code adjustment wheels 83. The support 81 is provided with multiple clearance protrusions 811 located beside the multiple code adjustment wheels 83. The outer side of each code adjustment wheel 83 is respectively provided with a clearance groove 831. When each code wheel 82 rotates to the correct code, each clearance protrusion 811 aligns and fits into the clearance groove 831 of the corresponding code adjustment wheel 83, thereby causing the support 81 to toggle the second driving portion 63, driving the stop button 6 to rotate and unlock.

[0051] Specifically, a code-changing seat 84 is slidably provided below the support 81, and a code-changing slot 841 is provided on the top of the code-changing seat 84. When an external force pushes the code-changing seat 84 until the code-changing slot 841 is aligned with the code-adjusting wheel 83, the code-adjusting wheel 83 can be separated from the code wheel 82 and fall into the code-changing slot 841. At this time, the code wheel 82 can be rotated to change other codes; after the code-changing seat 84 is reset, the code-adjusting wheel 83 resumes matching the code wheel 82, and the code adjustment is completed.

[0052] Specifically, the support 81 is provided with a limit seat 85. When the password is wrong, the limit seat 85 is aligned to prevent the code change seat 84 from moving, so as to avoid changing the password when the password is wrong. When the password is correct, the limit seat 85 staggers and removes the restriction of the code change seat 84.
