Before the embodiments are described in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The utility model discloses can be the embodiment that other modes realized. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of "including," "comprising," "having," and the like, herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present invention is not limited to the number of the element being one, and may include a plurality of the elements.

As shown in fig. 1-2, the present invention provides a zipper 10 with a locking function, wherein the zipper 10 can be used on articles such as backpacks, suitcases, traveling bags, handbags, etc. to prevent the articles from opening by themselves during the use, which may result in personal articles contained in the articles falling and losing or even being stolen. The present invention is described in this embodiment by taking a backpack as an example.

Zipper 10 includes zipper strip 12, first slider 14, second slider 16, first pull tab 18, and second pull tab 20. Fastener tape 12 is provided with fastener elements 22, and first slider 14 and second slider 16 are slidably attached to fastener elements 22. The first pull-tab 18 and the second pull-tab 20 are movably connected to the first slider 14 and the second slider 16 respectively through pull-tabs 24, for example, through holes are respectively arranged on the first slider 14, the second slider 16, the first pull-tab 18 and the second pull-tab 20, the through holes of the first slider 14 and the first pull-tab 18 are simultaneously sleeved by one pull-tab 24, and the through holes of the second slider 16 and the second pull-tab 20 are simultaneously sleeved by the other pull-tab 24. The first pull tab 18 and the second pull tab 20 are used for being pulled by a user, so that the first pull head 14 and the second pull head 16 are respectively driven to slide on the zipper teeth 22, and the zipper strip 12 is opened and closed.

The first pull piece 18 is provided with a first buckling part 26, the second pull piece 20 is provided with a second buckling part 28, when the first pull piece 14 and the second pull piece 16 are pulled together, the first buckling part 26 can be in buckling fit with the second buckling part 28 so that the first pull piece 18 is in buckling connection with the second pull piece 20, the first pull piece 14 and the second pull piece 16 are prevented from being opened automatically in the using process, and the anti-theft effect is achieved.

Referring to fig. 3 and 4, in the present embodiment, the first locking portion 26 is implemented as a locking post 26, and the second locking portion 28 is implemented as a locking hole 28 for locking with the locking post 26. More specifically, the first tab 18 and the second tab 20 are each a rounded sheet-like structure with a slightly domed middle. The first pull tab 18 has a first mating surface 30, and one end of the first mating surface 30 close to the first slider 14 protrudes outwards to form a first thickened portion 32; the second pull tab 20 has a second mating surface 34, and an end of the second mating surface 34 near the second slider 16 protrudes outward to form a second thickened portion 36. The first thickened portion 32 and the second thickened portion 36 are designed to facilitate the user pulling the first pull tab 18 and the second pull tab 20 by hand, so that the application of force is easier.

One end of the first mating surface 30, which is far away from the first slider 14, protrudes outward to form a fastening column 26, the fastening hole 28 is disposed through the second pull tab 20, and the position of the fastening hole 28 is disposed corresponding to the fastening column 26. When the first pull tab 18 is snapped into engagement with the second pull tab 20, the snap post 26 snaps into the snap hole 28 from the second mating surface 34, and the first thickened portion 32 and the second thickened portion 36 are offset from each other to avoid affecting the snap action. That is, the first pull tab 18 and the second pull tab 20 need to be misaligned when they are snap-connected, so as to avoid interference between the first thickened portion 32 and the second thickened portion 36.

In the illustrated embodiment, a first ring member 38 is disposed on the first mating surface 30 about the snap post 26, and a second ring member 40 is disposed on the second mating surface 34 about the snap hole 28. First ring member 38 and second ring member 40 are each provided as magnetic members and provide magnetic attraction between first ring member 38 and second ring member 40. First ring member 38 and second ring member 40 may be configured as magnets of opposite magnetic polarity, or may be configured such that one of the magnets is a magnet and the other is a metal block capable of magnetically attracting the magnet. In this embodiment, the first ring member 38 and the second ring member 40 are configured as magnets with opposite magnetic properties, so that the first pull tab 18 and the second pull tab 20 are attracted to each other when they are snap-connected, thereby enhancing the attraction between the two and preventing the two from being easily separated. While at the same time increasing the aesthetic appeal of the first and

second pull tabs

18, 20.

More specifically, a first groove 42 is disposed on the first mating surface 30 around the latch post 26, a second groove 44 is disposed on the second mating surface 34 around the latch hole 28, the first ring member 38 is received in the first groove 42, the second ring member 40 is received in the second groove 44, and the outer side surface of the first ring member 38 is flush with the first mating surface 30, and the outer side surface of the second ring member 40 is flush with the second mating surface 34, so that the latch post 26 and the latch hole 28 can be better latched to each other.

In the above embodiment, the first latching portion 26 is implemented as a latching post 26, and the second latching portion 28 is implemented as a latching hole 28 for latching engagement with the latching post 26. In some embodiments, the first latching portion 26 may be implemented as a latching post, and the second latching portion 28 may be implemented as a latching slot for latching engagement with the latching post 26. In other embodiments, the first latch portion 26 and the second latch portion 28 may be engaged with each other in other manners.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. Any changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
