Abstract
Description
Technical Field
[0001] This application relates to the field of luggage lock technology, and in particular to a zipper combination lock. Background Technology
[0002] Zipper combination locks are typically located on the opening mechanism of bags. They usually have two locking slots; simply engaging the zipper pull in these slots prevents the bag from opening. In current luggage locks, the combination lock works in conjunction with the zipper pull to achieve anti-theft functionality. Although the zipper cannot be opened, the zipper pull still has some freedom of movement. Therefore, in most cases, even after the zipper is locked with the combination lock, a small gap remains at the zipper pull. This gap, though small, can still be used by others to peek or steal items from inside, or to place contraband. It can also allow odors from smelly items to escape outside the bag, posing a security risk. Utility Model Content

[0027] Please see Figures 1 to 3 This application provides a zipper combination lock 2, installed on a bag to lock a zipper 1. The zipper 1 includes two pull rings 11. The zipper combination lock 2 includes a lock housing 21 and at least two limiting members 22. The lock housing 21 has two lock openings 211 spaced apart, which are used to lock one-to-one with the pull rings 11. The limiting members 22 are disposed between the lock openings 211 and the zipper 1, and the two limiting members 22 are spaced apart to form a gap area 23. The distance from one limiting member 22 to the other limiting member 22 is a, and the distance from the center line of one lock opening 211 to the center line of the other lock opening 211 is b, where a ≤ b. When the pull rings 11 are locked within the lock openings 211, the two pull rings 11 are located within the gap area 23.
[0028] The zipper combination lock 2 provided in this application includes at least two limiting members 22, which are spaced apart to form a gap region 23. The distance from the center of one limiting member 22 to the center of the other limiting member 22 is 'a', and the distance from the center line of one lock opening 211 to the center line of the other lock opening 211 is 'b', where a ≤ b. Figure 2 As shown, the center lines of the two locking openings 211 are denoted as L1 and L3, respectively. When the pull ring 11 is locked within the locking opening 211, the two pull rings 11 are located within the interval area 23. Since a≤b, the limiting member 22 limits the movement of the pull ring 11, effectively preventing the zipper pull 12 from sliding, avoiding others from peeping or stealing internal items, preventing others from placing prohibited items into the bag through gaps, preventing odors from escaping from the bag, and improving the safety of the bag.
[0029] Please see Figures 1 to 3In one embodiment, the zipper combination lock 2 further includes a mounting plate 24, which is connected to the lock housing 21, and the limiting member 22 is mounted on the mounting plate 24. Specifically, the mounting plate 24 and the lock housing 21 are connected by screws, thereby fixing the mounting plate 24 to the lock housing 21. The limiting member 22 is screwed onto the mounting plate 24 or snapped onto the mounting plate 24, thereby mounting the limiting member 22 onto the mounting plate 24. In other embodiments, the mounting plate 24 and the lock housing 21 are integrally formed, and the limiting member 22 and the mounting plate 24 are also integrally formed. This design facilitates direct mold opening for production, reduces production costs, and the integrally formed structure also helps to increase structural durability.
[0030] Please see Figures 1 to 3 In some embodiments, the limiting member 22 is mounted on the outside of the bag. Direct mounting of the limiting member 22 on the surface of the bag helps save parts and reduce costs.
[0031] Please see Figures 1 to 3 In some embodiments, when the pull ring 11 is locked within the lock opening 211, the two pull rings 11 are confined within the interval area 23, and the two pull rings 11 intersect along their respective length directions to form an included angle β, where β < 90°, for example, β is 30°, 45°, 60°, 89°, etc. If β is greater than 90°, it indicates that the positional distance between the two lock openings 211 is large, requiring a larger lock case 21, resulting in the combination lock 2 occupying too much area in the bag. The zipper 1 includes two pull heads 12 connected one-to-one with the two pull rings 11, and the length direction of the pull ring 11 is the direction from the pull ring 11 to the corresponding pull head 12. The two pull rings 11 intersect at an acute angle along their respective lengths, which makes it virtually impossible for the pull rings 11 to sway or slide when locked by the lock 211. The range of motion of the pull rings 11 is very small, and the gap between the two pull rings 11 is also very small. The limiting member 22 plays a good role in limiting the movement of the pull rings 11, preventing others from peeping or stealing the contents, preventing others from placing prohibited items into the bag through the gap, and improving the security of the bag.
[0032] Please see Figures 1 to 3 In some embodiments, the locking slots 211 and the limiting members 22 are both axially symmetrically distributed, and the axes of symmetry of the two locking slots 211 and the axes of symmetry of the two limiting members 22 coincide. The axis of symmetry is denoted as L2, as shown below. Figure 2As shown. Specifically, since the two pull rings 11 of the zipper 1 generally adopt the same structure, the lock opening 211 and the limiting member 22 are both axially symmetrically distributed. The pull ring 11 is placed in the corresponding lock opening 211 and forms an isosceles triangle structure with the lock shell 21, which is relatively stable and convenient to take out and put in the pull ring 11 from the lock opening 211. There will be no phenomenon that the pull ring 11 will be stuck in the lock opening 211 due to structural asymmetry.
[0033] Please see Figures 1 to 3 In some embodiments, the limiting member 22 is a cylindrical protrusion 221, and two cylindrical protrusions 221 are spaced apart to limit the pull ring 11 within the spaced area 23. See also... Figures 1 to 3 In some embodiments, the limiting member 22 is shaped like a cubic protrusion 222, and two cubic protrusions 222 are spaced apart to confine the pull ring 11 within the spaced area 23. The limiting member 22, being a cylindrical protrusion 221 or a cubic protrusion 222, has a simple structure, is easy to manufacture, and does not increase production costs excessively, while simultaneously preventing the zipper 1 from shaking or sliding. It is understood that in some embodiments, the limiting member 22 can also be other shapes, which are not specifically limited here.
[0034] Please see Figures 1 to 3 In some embodiments, the limiting member 22 is made of alloy or plastic. The lock housing 21 is made of alloy or plastic.
[0035] Please see Figures 1 to 3 In some embodiments, the lock housing 21 includes a combination wheel 212, and the lock housing 21 has a mounting groove 213 in which the combination wheel 212 is installed. The user only needs to rotate the combination wheel 212 to the corresponding combination and then press the switch on the lock housing 21 to open the lock 211 and release the pull ring 11.
[0036] The advantages or beneficial effects of the above technical solutions include at least the following:
[0037] The zipper combination lock 2 provided in this application includes at least two limiting members 22, which are spaced apart to form an interval region 23. The distance from the center of one limiting member 22 to the center of the other limiting member 22 is 'a', and the distance from the center line L1 of one lock opening 211 to the center line L3 of the other lock opening 211 is 'b', where a ≤ b. When the pull ring 11 is locked within the lock opening 211, both pull rings 11 are within the interval region 23. Since a ≤ b, the limiting members 22 limit the movement of the pull rings 11, effectively preventing the zipper pull 12 of the zipper 1 from sliding, avoiding others from peeping or stealing the internal items, preventing others from placing prohibited items into the bag through the gap, and improving the security of the bag.
[0038] In the zipper combination lock 2 provided in this application, the limiting member 22 is a cylindrical protrusion 221 or a cubic protrusion 222, which has a simple structure, is easy to manufacture, and will not increase the production cost too much, while achieving the purpose of preventing the zipper 1 from shaking or sliding.
