Description

Technical Field

[0001] The present invention relates to the technical field of clothing accessories, and more particularly to a slider with a lock. In addition, the present invention also relates to a zipper comprising the slider with a lock. Background Art

[0002] Zippers are a component of clothing accessories and are widely used in everyday clothing. The slider is a crucial component of the zipper, acting as the opening and closing mechanism for the zipper teeth. The most commonly used sliders on the market generally consist of four parts: the slider body, cap, hook, and pull tab.

[0003] In some situations where anti-theft measures are required, since conventional sliders do not have a lock structure themselves, they need to be connected to some external lock structure such as a combination lock or similar lock structure. This makes it heavy and cumbersome to use on bags other than suitcases. In addition, the pull tabs need to be pulled together and then buckled, which is a lot of steps and does not conform to the convenient and fast characteristics of zippers.

[0004] Existing technologies have structures that can lock zippers, but they require two sliders to be closed in the middle to complete the locking process; and an additional locking device is required, making the slider bulky; furthermore, these technologies themselves use non-locking elephant trunk sliders, which are not airtight enough.

[0005] In summary, how to provide a slider that is easy to lock and unlock is a problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a slider with a lock.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The core of the present invention is to provide a locking slider. By providing a movable portion, a locking portion, and a pass portion on the cap, the pull tab can move between the movable portion and the locking portion through the pass portion, thereby locking the slider. This eliminates the need for additional locks and facilitates operation. Another core of the present invention is to provide a zipper including the above-mentioned locking slider.

[0044] Please refer to Figure 1-13 .

[0045] The locking slider provided in this specific embodiment includes: a base 1, a cap 2 arranged on the upper part of the base 1, an elastic component arranged in the space enclosed by the cap 2 and the base 1, a code hook 4 located below the elastic component, and a pull tab 5 sleeved on the cap 2; the cap 2 is provided with a movable part 21, a locking part 23 and a passing part 22, and the pull tab 5 is movably arranged on the movable part 21 so as to overcome the elastic force of the elastic component to lift the code hook 4 to enable the slider to work normally; the pull tab 5 is separated from the contact with the code hook 4 at the locking part 23, and the code hook 4 locks the slider under the action of the elastic component; the pull tab 5 is provided with a passage portion 51 for passing through the passing part 22, so that it can move from the movable part 21 to the locking part 23 or from the locking part 23 to the movable part 21.

[0046] It should be noted that, during use, any part of the pull tab 5 can be passed through by the passing portion 22, so that the pull tab 5 can switch between the locking portion 23 and the movable portion 21. In this case, if the pull tab 5 shakes, it is easy to cause accidental locking or unlocking; preferably, a passage portion 51 can be provided at a specific position of the pull tab 5. During use, only the passage portion 51 can be passed through the passing portion 22, thereby realizing the switching of the pull tab 5 between the locking portion 23 and the movable portion 21.

[0047] It should be noted that the code hook 4 in this application document is shorter than the code hook 4 in the prior art, so that the code hook 4 can move in the movable portion 21 and the size of the cap 2 can be reduced.

[0048] When the slider with a lock is in use, it is only necessary to move the passage portion 51 of the pull tab 5 through the passage portion 22 to the locking portion 23. When the pull tab 5 is in the locking portion 23, it is out of contact with the code hook 4. Even if the pull tab 5 shakes in the locking portion 23, it will not contact the code hook 4. At this time, the code hook 4 is in the lower position under the action of the elastic component to achieve locking; when the slider needs to work normally, the pull tab 5 is moved so that the pull tab 5 moves from the locking portion 23 to the movable portion 21 through the passage portion 22. During the movement, the passage portion 51 of the pull tab 5 needs to pass through the passage portion 22 to achieve smooth movement of the pull tab 5. After the pull tab 5 moves to the movable portion 21, the pull tab 5 is pulled upward, and the force of the elastic component can be overcome to lift the code hook 4, so that the code hook 4 is in the upper position. At this time, the slider is pulled to open and close the zipper, and the slider works normally.

[0049] Compared with the prior art, the locked slider provided in this specific embodiment does not require the aid of an external lock structure to achieve locking of the slider, making the structure of the slider lighter and does not require the cooperation of two sliders, a single slider can achieve locking; and during operation, only the pull tab 5 needs to be simply moved to achieve locking and unlocking of the slider, which is convenient to operate and can meet the needs of users.

[0050] On the basis of the above embodiment, the movable part 21 can be provided in the first groove of the cap 2, the locking part 23 can be provided in the second groove of the cap 2, and the passing part 22 can be provided in the protrusion between the first groove and the second groove; the code hook 4 and the elastic component are both provided in the space enclosed by the first groove and the base 1.

[0051] During use, the pull tab 5 is sleeved on the cap 2, and the cap 2 is arranged on the upper part of the base 1. In the natural state, the elastic component is in a compressed state, which has a downward force on the code hook 4, so that the code hook 4 is located in a lower position to achieve locking; when the pull tab 5 moves to the first groove, since the pull tab 5 can move in the first groove, it can overcome the elastic force of the elastic component and lift the pull tab 5 upward, so that the pull tab 5 lifts the code hook 4, and the code hook 4 is in an upper position to achieve unlocking; after the pull tab 5 passes through the through portion 22 to the locking portion 23, under the elastic force of the elastic component, the code hook 4 moves downward again to the locked state.

[0052] Preferably, in order to save space, the elastic component can be set as a spring plate 3, and the spring plate 3 is a sheet-like structure, which is convenient for installation during the assembly process.

[0053] On the basis of the above embodiment, a gap may be set between the protrusion and the upper surface of the base 1 so that the pull tab 5 moves from the first groove to the second groove or from the second groove to the first groove.

[0054] In order to prevent the pull tab 5 from being mislocked or locked during shaking, a through hole for the cap 2 to pass through can be provided on the pull tab 5. The passage portion 51 is a structure formed by the through hole and the edge of the pull tab 5, and the thickness of the passage portion 51 is less than the thickness of other parts of the pull tab 5.

[0055] like Figure 3-6 As shown, the pull tab 5 is an asymmetric structure, and during the setting process, the distance between one side of the through hole and the edge is relatively close, and the thickness of the pull tab 5 here is relatively thin, that is, the passage portion 51.

[0056] Preferably, the gap between the through portion 22 and the upper surface of the base 1 is larger than the thickness of the through portion 51 and smaller than the thickness of other parts of the pull tab 5 except the through portion 51 .

[0057] During use, when it is necessary to move the pull tab 5 from the locking portion 23 to the movable portion 21 or from the movable portion 21 to the locking portion 23, the pull tab 5 needs to be rotated to a moving angle so that the passage portion 51 contacts the through portion 22, so that the pull tab 5 can pass through; during normal use, when the pull tab 5 shakes, it is difficult to shake the pull tab 5 to a point where the passage portion 51 contacts the through portion 22, and the through portion 22 can pass through, thereby avoiding mislocking or mislocking of the slider under the action of external force.

[0058] Preferably, the passage portion 51 may be provided on one side of the through hole in the width direction or at an angle between the width direction and the length direction of the through hole.

[0059] On the basis of the above embodiment, a buckle 11 may be provided on the base 1 , and a buckle portion 24 may be provided on the cap 2 for cooperating with the buckle 11 to detachably connect the cap 2 to the base 1 .

[0060] like Figure 1 、 2 As shown, the base 1 is provided with two sets of buckles 11 , and the two ends of the cap 2 in the length direction are provided with buckling parts 24 that cooperate with the buckles 11 .

[0061] On the basis of the above embodiment, in order to enable the code hook 4 to be smoothly lifted or pressed down, the code hook 4 can be set to a herringbone structure, and one of the base 1 and the code hook 4 is provided with a boss 12, and the other is provided with a recessed portion 41 for cooperating with the boss 12 to enable the code hook 4 to rotate relative to the base 1.

[0062] Preferably, the herringbone-shaped code hook 4 is placed flat with the opening side facing the through portion 22. When the pull tab 5 moves from the locking portion 23 to the movable portion 21, it can enter the opening of the code hook 4, thereby driving the code hook 4 to lift.

[0063] In addition to the above-mentioned locking slider, the present invention also provides a zipper including the locking slider disclosed in the above-mentioned embodiment. For the structures of other parts of the zipper, please refer to the prior art and will not be described in detail herein.

[0064] It should be noted that the first and second grooves mentioned in this application document are only used to distinguish the different positions and there is no order of precedence.

[0065] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other. Any combination of all the embodiments provided by the present invention is within the scope of protection of this invention and will not be described in detail here.

[0066] The above describes in detail the locking slider and zipper provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are merely intended to facilitate understanding of the method and core concepts of the present invention.
