The upper end of the center button 33 passes through the top of the housing 31, and the lower end of the center button 33 abuts against the top of the lock block 35. The bottom of the lock block 35 is connected to the base 32 via the reset spring 39 and is located between the code wheel 36 and the lock wheel 37. The top of the lock block 35 is provided with a lock tongue 351 for locking the lock buckle 21. The code wheel 36 drives the lock wheel 37 to be connected. A protrusion 352 is provided on one side of the lock block 35. The lock wheel 37 is provided with a groove 371 for accommodating the protrusion 352. The lock hook 38 is connected to the base 32 via the reset spring 39. The side button 34 drives the lock hook 38 and is connected to the housing 31 via the reset spring 39. The lock hook 38 is used to lock the switch 11 of the opening of the box 1. The housing 31 is provided with a central hole 311, a side hole 312 and a lock hole 313. The central hole 311 is located at the center of the housing 31 and is used to accommodate the central button 33. The central hole 311 is provided with a hole wall extending toward the inside of the housing 31. The outer side of the wall of the central hole 311 is provided with a side column for installing a reset spring 39. The side hole 312 is located at the side of the housing 31 and is used to accommodate the side button 34. The lock hole 313 is provided corresponding to the lock tongue 351 and is used to plug the lock buckle 21. The housing 31 is also provided with a password hole 314. The password hole 314 is used to expose the side of the password wheel 36 and the top surface with numbers. The password hole 314 exposes only one number corresponding to each password wheel 36 position, so that the user can turn the password wheel 36 and view the digital combination of the correct password.

[0048] In this embodiment, there are three code wheels 36 and three lock wheels 37, and the code wheels 36 and the lock wheels 37 are connected in driving correspondence. There are five reset springs 39, one of which is located between the lock block 35 and the base 32 to support the lock block 35 and reset the lock block 35, and the other two reset springs 39 are respectively sleeved outside the two side columns and located between the two side buttons 34 and the side wall of the center hole 311 to reset the side buttons 34, and the last two reset springs 39 are respectively sleeved outside the two lock hooks 38 and abut between the lock hooks 38 and the base 32 to reset the lock hooks 38.

[0049] When the combination lock 3 is in a locked state, the groove 371 of the lock wheel 37 and the protrusion 352 of the lock block 35 are staggered with each other, the top of the lock wheel 37 abuts against the bottom of the protrusion 352, and the center button 33 cannot be pressed, so that the lock block 35 will not move downward, and then the lock tongue 351 will not move downward, and the lock buckle 21 fastened by the lock tongue 351 will not break away from the shackles of the lock tongue 351 to lock the anti-theft chain 2, and the side button 34 is abutted by the lock block 35 and cannot be pressed and moves laterally, so that the lock hook 38 will not be squeezed to move downward. The lock hook 38 is lifted up by the return spring 39 so that the switch 11 of the box body 1 is locked in the lock hook 38, thereby locking the opening of the box body 1. When unlocking, it is only necessary to turn the code wheel 36 until the code is correct. The code wheel 36 will drive the lock wheel 37 to align the groove 371 of the lock wheel 37 with the protrusion 352 of the lock block 35. The lock wheel 37 no longer presses the lock block 35, and the center button 33 is pressed. The center button 33 squeezes the lock block 35 to move downward, thereby driving the lock tongue 351 to move downward. The lock tongue 351 moves downward and withdraws from the lock buckle 21. The anti-theft chain 2 is retracted and disengaged from the code lock 3 by the elastic force of the coil spring 14; the lock block 35 can move downward, and the side button 34 is pressed. When the side button 34 moves horizontally, it squeezes the lock hook 38 to move downward, thereby releasing the lock on the switch 11 of the box body 1. The luggage case with the anti-theft chain has a password lock 3 that locks the anti-theft chain 2 and the switch 11 of the case 1 in a linked manner, which saves the production cost of the luggage case. Only one password needs to be set, which is convenient for users to remember. The anti-theft chain 2 and the switch 11 of the case 1 are respectively controlled to be unlocked by the center button 33 and the side button 34. The return spring 39 of the side button 34 prevents the side button 34 from moving when the center button 33 presses the lock block 35, so that the unlocking of the anti-theft chain 2 and the switch 11 of the case 1 do not interfere with each other, and the luggage case has good convenience in use.

[0050] See also Figure 1 , Figure 2 , Figure 6As shown, the box body 1 is provided with a mounting groove 12, a rotating reel 13 is provided in the mounting groove 12, one end of the anti-theft chain 2 is fixed to the reel 13 and wound around the outside of the reel 13, and a coil spring 14 is provided in the reel 13 for resetting the reel 13. In this embodiment, the mounting groove 12 is formed to protrude outward from the front side of the box body 1, and an opening is provided at one end of the mounting groove 12 close to the combination lock 3, and the anti-theft chain 2 extends from the opening to be plugged into the combination lock 3, and the size of the opening is smaller than the size of the lock buckle 21, so that the lock buckle 21 will not be retracted into the mounting groove 12 by the elastic force of the coil spring 14, and it is convenient for the anti-theft chain 2 to be pulled out by grasping the lock buckle 21. The inner end of the coil spring 14 is fixed in the mounting groove 12 via a shaft, and the outer end of the coil spring 14 is fixedly connected to the inner wall of the reel 13. When the anti-theft chain 2 is pulled out, the reel 13 will rotate and drive the coil spring 14 to tighten; when the anti-theft chain 2 is loosened, the elastic force of the coil spring 14 causes the reel 13 to rotate, thereby driving the anti-theft chain 2 to be rewound back to the outside of the reel 13, thereby achieving the purpose of resetting the anti-theft chain 2, preventing the anti-theft chain 2 from being suspended outside the box body 1 and hooked on other items, and making the suitcase more beautiful.

[0051] See also Figures 4 to 5 As shown, the locking tongue 351 is disposed at the top of the locking block 35 and protrudes upward from the top surface of the locking block 35 . A first guiding inclined surface 354 is disposed on the side of the locking tongue 351 close to the insertion of the lock buckle 21 . When the lock buckle 21 is inserted into the lock hole 313, the lock buckle 21 contacts and slides over the first guide slope 354 of the lock tongue 351. In this process, the lock tongue 351 is squeezed downward due to the first guide slope 354, and the lock block 35 squeezes the reset spring 39 downward. After the front end of the lock buckle 21 completely slides over the lock tongue 351, the lock tongue 351 is no longer squeezed by the lock mouth, and the elastic force of the reset spring 39 lifts the lock block 35, so that the lock tongue 351 is inserted into the lock buckle 21 to fix the anti-theft chain 2; by shuffling the code wheel 36 so that the groove 371 of the lock wheel 37 is offset from the protrusion 352 of the lock block 35, it is possible to prevent the anti-theft chain 2 from being unlocked by accidentally touching the center button 33.

[0052] See also Figures 4 to 5 , Figure 8As shown, the top of the lock block 35 is also provided with a first wedge block 353 protruding upward, and the bottom of the side button 34 is provided with a second wedge block 341 protruding downward. The first wedge block 353 and the second wedge block 341 are respectively provided with wedge surfaces that contact each other and move relatively. In this embodiment, there are two first wedge blocks 353, and the two first wedge blocks 353 are symmetrically arranged with the center button 33 as the axis, and the line connecting the lock tongue 351 and the center button 33 is perpendicular to the line connecting the two first wedge blocks 353, the wedge surface of the first wedge block 353 is parallel to the wedge surface of the second wedge block 341, and the wedge surface of the first wedge block 353 gradually tilts upward from the outside to the inside, and the number of the second wedge blocks 341 is the same as the number of the first wedge blocks 353. When the lock block 35 is in the locked state, the second wedge block 341 is located on the side of the first wedge block 353 away from the center button 33, and the highest point of the wedge surface of the second wedge block 341 abuts against the lowest point of the wedge surface of the first wedge block 353. However, because the lock block 35 is abutted by the lock wheel 37 and cannot move downward, even if the side button 34 is pressed, the second wedge block 341 abuts against the first wedge block 353, and the side button 34 will not move laterally, thereby not squeezing the lock hook 38 to move downward, and the switch 11 of the box body 1 will not be unlocked. After the lock block 35 is unlocked, the side button 34 is pressed, and the side button 34 moves toward the center button 33, and the second wedge block 341 squeezes the first wedge block 353. Due to the cooperation of the wedge surface, the first wedge block 353 moves downward, and the side button 34 can squeeze the lock hook 38 to move downward and release the lock on the switch 11 of the box body 1.

[0053] See also Figures 3 to 5As shown, there are two side buttons 34, which are symmetrically arranged with the center button 33 as the axis; there are two lock hooks 38, which are respectively arranged below the two side buttons 34; the base 32 is also provided with a through hole 322 for accommodating the lock hook 38, and the through hole 322 allows the lock hook 38 to pass through to engage the switch 11 of the box body 1. A third wedge block 381 is provided on the top of the lock hook 38, and a fourth wedge block 342 is provided on the side button 34. The third wedge block 381 and the fourth wedge block 342 are respectively provided with wedge-shaped surfaces that contact each other and move relatively. In this embodiment, the cross-sectional area of ​​the third wedge block 381 of the lock hook 38 is larger than the cross-sectional area of ​​the lock hook 38 body, and the inner diameter of the through hole 322 of the base 32 is larger than the outer diameter of the lock hook 38 body and smaller than the outer diameter of the third wedge block 381, so that the reset spring 39 can be mounted on the lock hook 38 body while the two ends can respectively resist the third wedge block 381 and the base 32, thereby supporting the lock hook 38 and resetting the lock hook 38. The wedge surface of the third wedge block 381 is parallel to the wedge surface of the fourth wedge block 342 and both are gradually inclined upward from the outside to the inside. The activity principle of the third wedge block 381 and the fourth wedge block 342 is the same as the activity principle of the first wedge block 353 and the second wedge block 341. When the combination lock 3 is in a retracted state, the lowest point of the wedge surface of the third wedge block 381 abuts against the highest point of the wedge surface of the fourth wedge block 342. Since the first wedge block 353 abuts against the second wedge block 341, the side button 34 cannot move laterally, so that the fourth wedge block 342 cannot squeeze the third wedge block 381 to move downward, thereby achieving the purpose of locking the switch 11 of the box body 1.

[0054] See also Figures 4 to 5 , Figure 8 As shown, the lower end of the lock hook 38 is provided with a second guide slope 382, ​​and the second guide slope 382 is located on the side of the lock hook 38 close to the switch 11 of the box 1. In this embodiment, the second guide slope 382 guides the switch 11 of the box 1, and the second guide slope 382 gradually tilts upward from the outside to the inside. When the switch 11 of the box 1 is inserted into the lock hook 38, the switch 11 abuts against the second guide slope 382 and slides over the second guide slope 382. In this process, the force exerted by the switch 11 on the second guide slope 382 causes the lock hook 38 to move downward, and the third wedge block 381 squeezes the return spring 39 for compression and deformation. When the switch 11 completely slides over the second guide slope 382, ​​the elastic force of the return spring 39 lifts the third wedge block 381, so that the highest point of the second guide slope 382 abuts against the bottom of the base 32, and the switch 11 is locked in the lock hook 38.

[0055] See also Figure 7As shown, a shaft sleeve 361 is provided at the bottom of the code wheel 36, and a limiting groove 362 is provided on the side wall of the shaft sleeve 361; a rotating shaft 372 is provided at the top of the lock wheel 37, and a limiting boss 373 is provided on the outer side of the rotating shaft 372, the rotating shaft 372 is accommodated in the shaft sleeve 361, and the limiting boss 373 is accommodated in the limiting groove 362. In this embodiment, the base 32 is provided with a wheel groove (not shown in the figure) for accommodating the lock wheel 37, and the bottom of the lock wheel 37 is provided with a connecting shaft (not shown in the figure) for rotatably connecting with the base 32, and the cooperation between the limiting boss 373 and the limiting groove 362 enables the code wheel 36 to drive the lock wheel 37 to rotate when rotating, so that the groove 371 of the lock wheel 37 is staggered or aligned with the protrusion 352 of the lock block 35, so as to realize the function of locking or unlocking.

[0056] See also Figures 4 to 5 As shown, the base 32 is provided with a receiving groove 321, and the receiving groove 321 is used to accommodate the reset spring 39 and the lock block 35. In this embodiment, the height of the groove wall of the receiving groove 321 near the password wheel 36 is less than the height of the groove wall near the lock tongue 351, so as to install the lock wheel 37 and the lock block 35 to prevent the groove wall from interfering with the lock block 35 from moving downward relative to the lock wheel 37.

[0057] In summary, the present invention saves the production cost of the suitcase by setting a password lock 3 to lock the anti-theft chain 2 and the switch 11 of the box body 1 in linkage. Only one password needs to be set, which is convenient for users to remember. The unlocking of the anti-theft chain 2 and the switch 11 of the box body 1 are controlled respectively by the center button 33 and the side button 34. The return spring 39 of the side button 34 prevents the side button 34 from moving when the center button 33 presses the lock block 35, so that the unlocking of the anti-theft chain 2 and the switch 11 of the box body 1 do not interfere with each other, and has good convenience in use.
