Description

Technical Field

[0001] The invention relates to an anti-theft lock structure of a luggage case, and belongs to the field of luggage case lock structures. Background Art

[0002] A suitcase, also known as a travel suitcase or a trolley case, is a box that is used to carry items when going out. It is one type of luggage. Usually, a suitcase is used to carry clothes, personal care products, and souvenirs needed for the journey. As people travel for work and for travel, they use suitcases of different sizes when traveling to carry clothes, daily necessities, electronic products, etc.

[0003] Anti-theft locks are often installed on suitcases. However, due to the complex structure and function of the anti-theft locks on suitcases, the designers of the suitcase locks often need to consider the size of the suitcase lock structure, which results in too many components being placed in a limited space, resulting in the thickness or size of each component of the suitcase lock being too small, resulting in the problem of low lock structure strength. What is rare on the market now is an anti-theft lock structure with strong structural strength and good cost control. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned problem. The present invention is designed to simplify the structure, so that not only the strength of each component of the anti-theft lock structure is higher, but also the anti-theft locking and anti-theft performance are guaranteed without significantly changing the volume of the anti-theft lock structure; another important effect is that the buckle can be unlocked by pressing the movable lock buckle, thereby opening the suitcase body; the unlocking method is simplified to avoid secondary operation.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A luggage anti-theft lock structure comprises an upper lock body, a lower lock body, a dynamic lock buckle, a fixed lock buckle and a lock core; the fixed lock buckle is fixed on the upper lock body, and the lower lock body has a dynamic lock cavity, the dynamic lock buckle is arranged in the dynamic lock cavity and is movably connected with the side wall of the dynamic lock cavity through a pin shaft; the dynamic lock buckle comprises a lock buckle part and a pressing part, the lock buckle part is hook-shaped and extends from the upper part of the dynamic lock cavity and is locked with the fixed lock buckle, a spring in a compressed state is arranged on the back side of the lock buckle part, a lock hole is arranged on the pressing part, and the lower end of the pressing part extends from the lower side of the dynamic lock buckle; the lock core is arranged on the lower lock body and extends into the dynamic lock cavity, the lock core passes through the lock hole on the pressing part and is connected to the lock plate, and the lock plate is controlled to rotate by the lock core to lock or unlock the pressing part.

[0007] Furthermore, the fixed lock buckle is cylindrical and is laterally arranged on the upper lock body. The dynamic lock buckle uses the pin shaft as a fulcrum, and pressing its pressing part causes the lock buckle part to tilt up to unlock the upper lock body.

[0008] Furthermore, the lock hole is a waist-shaped hole or a long strip-shaped hole, and the lock plate matches the shape of the lock hole and is eccentrically connected to the lock core.

[0009] Furthermore, the left and right sides of the dynamic lock buckle are bent, and the bent parts are connected to the left and right side walls of the dynamic lock cavity through the pin shaft.

[0010] Furthermore, a pressing groove is provided on the lower lock body at the lower side of the lock core, and the pressing groove is used to cooperate with the pressing action of the pressing part.

[0011] Furthermore, it also includes an upper clamping mechanism, which includes a lock cover and a lock cover clamping piece. The lock cover covers the upper lock body and is connected to the upper end of the lower lock body. A threaded seat is provided on the inner side of the lock cover. The lock cover clamping piece is provided on the inner side of the suitcase. The screw passes through the lock cover clamping piece, the suitcase, and the upper lock body in sequence and is connected to the threaded seat of the lock cover clamping piece to clamp the upper lock body.

[0012] Furthermore, it also includes a lower clamping mechanism, which includes a first clamping member and a second clamping member. The first clamping member is provided with a threaded seat, and the first clamping member is arranged in the dynamic lock cavity. The threaded seat passes through the lower lock body and the luggage case and is fixed to the second clamping member.

[0013] The beneficial effects of the present invention are:

[0014] 1. The structure of this structure is simple to operate. You only need to press the lock buckle to unlock the buckle, so as to open the suitcase body; reduce the secondary operation of unlocking the lock buckle; improve the user experience of the anti-theft lock;

[0015] 2. The overall number of parts of this structure is relatively small, so that the strength of each part can be strengthened under the requirements of the box lock structure of the same volume, thereby improving the overall anti-theft performance of the anti-theft lock structure;

[0016] 3. The structure of this structure is simple and the strength of each component is high. On the basis of not increasing the volume of the luggage anti-theft lock structure, the anti-theft performance of the anti-theft lock can be guaranteed. Compared with the existing anti-theft lock structure with a complex structure and more parts, the strength and service life of the anti-theft lock can be guaranteed; in addition, due to the simplified design of the anti-theft structure, all parts can be made of full metal materials, thereby ensuring its anti-theft performance;

[0017] 4. The material evaluation thickness of each component in this structure can reach 0.8-1.2mm; compared with the complex luggage anti-theft lock structure, under its limited design space, it is often only possible to use plastic materials to control costs. This structure can ensure the structural strength of each part and control the manufacturing cost of the anti-theft lock on the basis of ensuring its anti-theft performance;

[0018] 5. In this structure, the upper lock body and the lower lock body are locked or unlocked through the lever structure design of the dynamic lock buckle, and then the lever structure of the dynamic lock buckle is locked or unlocked by the lock core, which has a serial locking effect. The main point of this design is the development and extension of the lock core function. The lock core structure adopts the existing lock core, and the development difficulty is reduced, so that the cost can be effectively controlled;

[0019] 6. The design of the clamping structure in the structure, especially the upper clamping structure, can not only protect the installation points of the upper lock body and the lower lock body, and avoid the problem of external disassembly of the anti-theft lock. In addition, due to the clamping structure of the device, a clamping method is adopted instead of directly fixing the upper and lower lock bodies to the suitcase, thereby ensuring that the anti-theft lock structure will not be affected by the material of the suitcase, thereby improving its versatility.

DETAILED DESCRIPTION

[0026] Example 1

[0027] like Figure 1-4 As shown, an anti-theft lock structure for a luggage case of the present invention comprises an upper lock body 1, a lower lock body 3, a dynamic lock buckle 5, a fixed lock buckle 2 and a lock core.

[0028] The fixed lock buckle 2 is cylindrical and is transversely arranged on the upper lock body 1 .

[0029] A square tubular dynamic lock cavity 18 is provided on the lower lock body 3. The dynamic lock buckle 5 is arranged in the dynamic lock cavity 18 and is movably connected to the side wall of the dynamic lock cavity 18 through a pin shaft. The dynamic lock buckle 5 includes a lock buckle part and a pressing part 8. The lock buckle part is hook-shaped and extends from the upper part of the dynamic lock cavity 18 and cooperates with the fixed lock buckle 2 to lock. The lower end of the pressing part 8 extends from the lower side of the dynamic lock buckle 5, and the left and right sides of the dynamic lock buckle 5 are bent. The bent part is connected to the left and right side walls of the dynamic lock cavity 18 through the pin shaft. The dynamic lock buckle 5 uses the pin shaft as a fulcrum, and pressing its pressing part 8 makes the lock buckle part tilt up to unlock the upper lock body 1.

[0030] A spring 7 in a compressed state is arranged on the back side of the lock catch part, a lock hole 10 is arranged on the pressing part 8, and the lock hole 10 is a waist-shaped hole or a long strip-shaped hole. The lock core 4 is arranged on the lower lock body 3 and extends into the dynamic lock cavity 18. The lock core 4 passes through the lock hole 10 on the pressing part 8 and is connected to the lock plate 9. The lock plate 9 matches the shape of the lock hole 10 and is eccentrically connected to the lock core 4. The lock plate 9 is controlled by the lock core to rotate to lock or unlock the pressing part 8.

[0031] A pressing groove 6 is provided on the lower lock body 3 at the lower side of the lock core 4 , and the pressing groove 6 is used to cooperate with the pressing action of the pressing portion 8 .

[0032] Example 2

[0033] On the basis of the structure of Example 1, in order to ensure that the upper and lower lock bodies 3 cannot be disassembled from the outside of the suitcase, the installation point of the anti-theft lock is protected; the anti-theft lock structure of the suitcase is designed with an upper clamping mechanism and a lower clamping mechanism.

[0034] The upper clamping mechanism includes a lock cover 12 and a lock cover clamping piece 13. The lock cover 12 covers the outside of the upper lock body 1 and is connected to the upper end of the lower lock body 3. A threaded seat is provided on the inner side of the lock cover 12. The lock cover clamping piece 13 is provided on the inner side of the suitcase. The screw passes through the lock cover clamping piece 13, the suitcase, and the upper lock body 1 in sequence and is connected to the threaded seat of the lock cover clamping piece 13 to clamp the upper lock body 1.

[0035] The lower clamping mechanism includes a first clamping member 14 and a second clamping member 16 . A threaded seat is provided on the first clamping member 14 . The first clamping member 14 is disposed in the dynamic lock cavity 18 . The threaded seat passes through the lower lock body 3 and the luggage case and is fixed to the second clamping member 16 .

[0036] When the luggage case structure is unlocked, two structures are required to unlock it: the first structure is a lock core 4 that needs to be unlocked by a key. The lock core 4 can fix the dynamic lock buckle 5, and the pressing part 8 of the dynamic lock body is stuck by the lock plate 9, so that the dynamic lock buckle 5 cannot move no matter how it is pressed, and it plays the role of a lock. The unlocking method is to rotate the lock core 4 by the key so that the lock plate 9 and the lock hole 10 correspond, so that the lock plate 9 can pass through the lock hole 10; the second structure is that the hook-shaped structure of the lock buckle part locks the fixed lock buckle 2. After the upper lock body 1 and the lower lock body 3 are installed on the luggage case, when the dynamic lock buckle 5 is locked to the fixed lock buckle 2, the elastic force of the spring 7 is used to ensure that the dynamic lock buckle 5 is always locked to the fixed lock buckle 2 without the action of external force; when unlocking is required, the pressing part 8 of the dynamic lock buckle 5 is pressed to achieve unlocking.

[0037] The above embodiments are merely examples for the purpose of clear description, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications may be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
