[0002] In the design of hard luggage, closure is usually achieved by zippers or buckles. Compared with zipper closure, luggage closed with buckles have greater advantages in terms of safety and protection, but also bring some challenges in the design of the locking structure. In existing buckle-closed luggage, the buckle and locking components are usually set separately, and the buckle is driven to be loosened or locked by a linkage mechanism. This structure is prone to malfunction during use due to the large number of linkage mechanism parts. In addition, the existing linkage mechanism occupies a large space, which is not conducive to use on small hard luggage. Utility Model Content

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-4 As shown, a customs lock suitable for hard luggage includes a lock box 3 and a lock buckle 4. The lock box 3 and the lock buckle 4 are respectively fixedly mounted on the two surfaces of the box cover 1 and the box body 2 that are buckled together. A mounting base 5 is fixedly provided on the box cover 1. The upper end of the mounting base 5 is fixedly connected to a main bracket 6. The lock box 3 is fixedly mounted in the main bracket 6. The use of the main bracket 6 can make the lock box 3 and the mounting base 5 modular. If the lock box 3 or the mounting base 5 needs to be replaced or maintained, the modular design can achieve rapid disassembly and replacement, thereby improving the convenience of maintenance and production; a main pressure plate 7, a lock hook 8 and a slidable push block 9 are provided in the mounting base 5. The number and position of the lock hook 8 are determined. It corresponds one to one with the lock buckle 4 and is used to hook the lock buckle 4. The lock hook 8 is rotatably connected to the mounting seat 5. A return torsion spring 81 is provided between the lock hook 8 and the mounting seat 5. The main pressure plate 7 is used to press the lock hook 8 so that the lock hook 8 disengages from the lock buckle 4. A main pressure plate pressing mechanism 31 is provided in the lock box 3. A return spring 71 is provided between the main pressure plate 7 and the mounting seat 5. A compression spring 91 is provided between the rear end of the push block 9 and the mounting seat 5. A stop block 92 is integrally provided on the push block 9. The stop block 92 is used to abut against the inner surface of the mounting seat 5 to prevent the push block 9 from sliding off the mounting seat 5. When the lock buckle 4 is inserted into the mounting seat 5 and is hooked by the lock hook 8, the push block 9 abuts against the lock buckle 4.

[0019] The lock box 3 is provided with a lock core 32, a combination lock assembly 33 and a charging assembly 34 inside. The upper surface of the lock box 3 is hinged with a charging cover 341. The lock box 3 is fixed with a charging interface 342. The charging interface 342 is connected to a charging line 343, which provides travelers with a convenient function of charging electronic devices and further improves the user experience. The combination lock assembly 33 is used to lock the main pressure plate pressing mechanism 31. The combination lock assembly 33 includes a wheel shaft 331 and multiple combination wheels 332. The lock box 3 is provided with a combination wheel toggle slot 331. 5. The code wheels 332 pass through the code wheel toggle slots 35 in a one-to-one correspondence. A boss 333 is provided on the inner surface of the code wheel 332. A groove 334 extending along the axial direction is provided on the wheel shaft 331. The groove 334 is used to cooperate with the boss 333. The wheel shaft 331 is provided with positioning holes 335 at intervals, the same number as the code wheels 332 and smaller in diameter than the outer diameter of the wheel shaft. The code wheel 332 is sleeved on the positioning holes 335 and rotates freely within the positioning holes 335. A transverse push block 336 is integrally provided at the end of the wheel shaft 331.

[0020] The pressure plate pressing mechanism 31 includes a button 311, an extension column 321 is integrally provided at the lower end of the lock cylinder 32, and a support plate 322 is provided on the outer surface of the extension column 321. The lock cylinder 32 abuts against the upper end of the main pressure plate 7 and the outer part of the lock cylinder 32 is sleeved with the button 311. The upper surface of the button 311 passes through the lock box 3, and the lower end of the button 311 abuts on the support plate 322. The button 311 is integrally provided with a longitudinal pressure block 312 on the outer surface near one end of the password lock assembly 33, and a key socket 313 is provided on the upper end surface of the button 311. Blade guard rods 314 are provided on both sides of the lower end of the button 311.

[0021] When the lock core 32 and the combination lock assembly 33 are in the locked state, when the lock core 32 is in the locked state, the blade 323 inside the lock core 32 is partially exposed outside the lock core 32 and is blocked by the blade blocking rod 314, so that the lock core 32 cannot move downward, thereby preventing it from pressing the main pressure plate 7, keeping the lock hook 8 firmly hooked on the lock buckle 4; when the combination lock assembly 33 is in the locked state, the boss 333 on the combination wheel 332 is misaligned with the groove 334 on the wheel shaft 331, so that the wheel shaft 331 cannot move axially, and the horizontal push block 336 is against the bottom of the longitudinal pressure block 312, preventing the button 311 from being pressed down to press the main pressure plate 7.

[0022] When the combination lock assembly 33 of this embodiment is in the unlocked state, the user toggles the combination wheel 332 through the combination wheel toggle slot 35, so that the boss 333 in the combination wheel 332 is aligned with the groove 334 on the wheel axle 331, and the wheel axle 331 can move axially. By pressing the button 311, the longitudinal pressure block 312 pushes the transverse push block 336 to move axially, so that the button 331 can smoothly press down the main pressure plate 7.

[0023] When the lock core 32 is in the unlocked state in this embodiment, the user inserts the key into the key socket 313 and rotates it, so that the blade 323 inside the lock core 32 is retracted into the lock core 32, and the lock core 32 can move downward smoothly to press the main pressure plate 7.

[0024] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
