The locking member 13 locks the relative position between the upper connecting member 11 and the lower pressing plate 12 so that the upper connecting member 11 and the lower pressing plate 12 clamp the zipper 10 together. The mechanical code lock 2 locks or releases the zipper head 20 through a code. The locking plate 1 prevents the zipper head 20 from detaching from the zipper 10 by abutting against the zipper head 20. First, the locking plate 1 can be used in conjunction with the zipper head 20. The locking plate 1 acts as the abutting top at the starting end or the end of the zipper 10 to prevent the zipper head 20 from escaping from the zipper 10. At the same time, the locking member 13 is used to lock the relative position between the upper connecting member 11 and the lower pressing plate 12 so that the upper connecting member 11 and the lower pressing plate 12 can clamp the zipper 10 together. The clamping between the upper connecting member 11 and the lower pressing plate 12 can fix the zipper-type password lock of the utility model in any device with a zipper 10. When in use, the user only needs to pull open the zipper 10 to be installed, and then place the zipper-type password lock at the end of the zipper 10, and clamp the two sides of the zipper 10 by clamping between the upper connecting member 11 and the lower pressing plate 12. At this time, the zipper-type password lock of the utility model has been fixed on the zipper 10, thereby realizing the detachable connection between the zipper-type password lock and the zipper 10. The locking can be realized by only locking the zipper head 20 of the zipper 10 by using the mechanical password lock 2. More specifically, as follows:
[0029] Please refer to Figures 7 and 8, the upper connecting member 11 is provided with a threaded hole 111, the lower pressing plate 12 is provided with a through hole 121 corresponding to the threaded hole 111, the locking member 13 is a bolt, the threaded hole 111, the through hole 121 and the locking member 13 correspond to each other, and the locking member 13 is connected to the threaded hole 111 through the through hole 121 to lock the relative position between the upper connecting member 11 and the lower pressing plate 12. Preferably, there are two threaded holes 111, two through holes 121 and the locking member 13, and the two threaded holes 111, the through holes 121 and the locking member 13 are symmetrically arranged, but not limited thereto.
[0030] Please refer to Figures 7 and 8 An upper guide rail structure 112 is provided on the upper connecting member 11, and an upper tightening opening 1121 is formed at the upper guide rail structure 112. A lower guide rail structure 122 is provided on the lower pressing plate 12, and a lower tightening opening 1221 is formed at the lower guide rail structure 122. Both the upper guide rail structure 112 and the lower guide rail structure 122 are in an "eight" shape.
[0031] Please refer to Figures 1 to 6 For example, the mechanical combination lock 2 includes a housing 21, a sliding drive member 22, a combination lock 23 and a lock tongue 24. The housing 21 is connected to the lower pressing plate 12. The sliding drive member 22 is slidably disposed inside the housing 21. The combination lock 23 is used to lock the movement of the sliding drive member 22. The lock tongue 24 moves under the drive of the sliding drive member 22 and has a locking position for locking the zipper head 20 (see for details). Figures 5 and 6 ) and a release position for releasing the zipper head 20 (see Figure 3 to Figure 4 ).
[0032] Please refer to Figures 5 to 10 The combination lock 23 includes a combination knob 231 and a first elastic member 232. The combination knob 231 is installed between the housing 21 and the sliding driving member 22. The sliding driving member 22 is provided with a snap-fitting hole 221 corresponding to the combination knob 231. The first elastic member 232 is elastically compressed and arranged between the housing 21 and the combination knob 231. A snap-fitting portion 2211 is arranged in the snap-fitting hole 221. The rotating portion of the combination knob 231 has a snap-fitting tooth 2311 corresponding to the snap-fitting portion 2211. The aperture of the snap-fitting hole 221 is larger than the aperture of the rotating portion. When the password of the combination knob 231 is correct, the snap-fitting tooth 2311 is opposite to the snap-fitting portion 2211 and the two can mesh with each other (see when meshing). Fig.10), the engagement between the engaging teeth 2311 and the engaging portion 2211 can provide a distance for the sliding drive member 22 to move backward relative to the rotating portion, so that the sliding drive member 22 can move backward relative to the lock tongue 24. After the sliding drive member 22 moves backward, it no longer presses against the lock tongue 24, and the lock tongue 24 moves from the locked position to the unlocked position. When the password of the password knob 231 is wrong, the engaging teeth 2311 and the engaging portion 2211 are staggered, and the engagement between the engaging teeth 2311 and the engaging portion 2211 cannot be engaged, so that the password knob 231 can only rotate in place, so as to limit the movement of the sliding drive member 22, and the sliding drive member 22 cannot move relative to the password knob 231. The sliding drive member 22 continues to press against the lock tongue 24, and the lock tongue 24 is locked in the locked position (see the state). Fig.10 In this embodiment, three password knobs 231 are provided, and the engaging holes 221 correspond to the password knobs 231 one by one, but the present invention is not limited thereto.
[0033] Please refer to Figure 4 The mechanical combination lock 2 also includes a second elastic member 25, which is elastically compressed and arranged between the lock tongue 24 and the housing 21. The second elastic member 25 provides an elastic force, which constantly makes the lock tongue 24 have a tendency to move from the locked position to the unlocked position, so that the lock tongue 24 is maintained in the unlocked position without being affected by external forces.
[0034] Please refer to Figures 5 to 10 The lock tongue 24 switches between the locking position and the unlocking position by lifting. The output end of the sliding drive member 22 has a retractable abutting head 222, and the lock tongue 24 is escalably arranged on the housing 21. The lock tongue 24 is provided with a matching driving part 241 corresponding to the abutting head 222. The abutting head 222 is retracted to abut the matching driving part 241 and the lock tongue 24 is lifted and lowered.

The matching between the arc surface and the matching arc surface can guide the driving of the lock tongue 24 to lift and lower.
[0035] Please refer to Figures 3 to 10 The working process of the zipper combination lock 100 of the utility model is as follows:
[0036] When in use, the user only needs to open the zipper 10 to be installed, and then place the zipper combination lock at the end of the zipper 10, and use the clamping between the upper connecting piece 11 and the lower pressing plate 12 to clamp the two sides of the zipper 10. At this time, the zipper combination lock of the utility model has been fixed on the zipper 10.
[0037] After the zipper head 20 is brought close to the clamp-type code zipper 10 of the utility model, the buckle of the zipper head 20 is inserted under the lock tongue 24, and the sliding driving member 22 is pushed toward the lock tongue 24. The lock tongue 24 overcomes the elastic force of the second elastic member 25 and moves downward to lock the zipper head 20 (see Figures 5 and 6 ), the code knob 231 is turned, the engaging teeth 2311 are staggered with the engaging portion 2211, and the engaging teeth 2311 and the engaging portion 2211 cannot mesh, so that the code knob 231 can only rotate in the original position, so as to limit the movement of the sliding driving member 22, and the sliding driving member 22 cannot move relative to the code knob 231. The sliding driving member 22 continues to keep the top of the lock tongue 24, and the lock tongue 24 is locked in the locked position.
[0038] When the lock needs to be released, the password knob 231 is turned. When the password of the password knob 231 is correct, the engaging teeth 2311 face the engaging portion 2211 and the two can mesh with each other (see Fig.10 ), the meshing between the engaging teeth 2311 and the engaging portion 2211 can provide a distance for the sliding drive member 22 to move backward relative to the rotating portion, so that the sliding drive member 22 can move backward relative to the lock tongue 24. After the sliding drive member 22 moves backward, it no longer presses against the lock tongue 24 (i.e., pushes the sliding drive member 22 in a direction away from the lock tongue 24), and the lock tongue 24 moves from the locked position to the unlocked position under the elastic action of the second elastic member 25. When the password of the password knob 231 is wrong, the engaging teeth 2311 are staggered with the engaging portion 2211, and the engagement between the engaging teeth 2311 and the engaging portion 2211 cannot be engaged, so that the password knob 231 can only rotate in place, so as to limit the movement of the sliding drive member 22, and the sliding drive member 22 cannot move relative to the password knob 231, and the sliding drive member 22 continues to press against the lock tongue 24, and the lock tongue 24 remains in the locked position (see Fig. 9 ).
[0039] By combining the locking splint 1 and the mechanical code lock 2, the locking splint 1 includes an upper connecting member 11, a lower pressing plate 12 and a locking member 13. The upper connecting member 11 is connected to the bottom of the mechanical code lock 2, and the lower pressing plate 12 is located below the upper connecting member 11, so that a clamping space 14 for accommodating the zipper 10 is formed between the upper connecting member 11 and the lower pressing plate 12. The locking member 13 locks the relative position between the upper connecting member 11 and the lower pressing plate 12 so that the upper connecting member 11 and the lower pressing plate 12 clamp the zipper 10 together. The mechanical code lock 2 locks or releases the zipper head 20 through the code, and the locking splint 1 prevents the zipper head 20 from detaching from the zipper 10 by abutting against the zipper head 20. First, the locking splint 1 can be used in conjunction with the zipper head 20, and the locking splint 1 acts as the abutment top at the starting end or the end of the zipper 10 to prevent the zipper head 20 from escaping from the zipper 10. At the same time, the locking member 13 is used to lock the relative position between the upper connecting member 11 and the lower pressing plate 12 so that the upper connecting member 11 and the lower pressing plate 12 can clamp the zipper 10 together. The zipper-type combination lock of the utility model can be fixed in any device with a zipper 10 by clamping between the upper connecting member 11 and the lower pressing plate 12. When in use, the user only needs to pull open the zipper 10 to be installed, and then place the zipper-type combination lock at the end of the zipper 10, and clamp the two sides of the zipper 10 by clamping between the upper connecting member 11 and the lower pressing plate 12. At this time, the zipper-type combination lock of the utility model has been fixed on the zipper 10, thereby realizing a detachable connection between the zipper-type combination lock and the zipper 10, and locking can be achieved by only locking the zipper head 20 of the zipper 10 using the mechanical combination lock lock device 2.
