For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0038] The zipper in the prior art is provided with two sliders, and the pull tabs of the two sliders cannot be connected together, so the purpose of theft prevention cannot be achieved.
[0039] The following is a preferred embodiment of an anti-theft zipper provided by the utility model that can solve the above technical problems.
[0040] Please refer to Figure 1 and Figure 2 The preferred embodiment of the utility model provides an anti-theft zipper, which includes two bases 2 and an anti-theft pull tab 1.
[0041] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The anti-theft pull tab 1 includes two detachably connected docking pieces 11, which are strip-shaped and include a first connection portion 111, a second connection portion 112 and a clamping block 113 arranged in sequence along its length direction. The first connection portion 111 is rotatably connected to the base 2 at one end away from the second connection portion 112. The second connection portion 112 is sheet-shaped, and its two opposite surfaces in the thickness direction are respectively a first side surface 1121 and a second side surface 1122. The second connection portion 112 is provided with a clamping groove 1123, which includes a first opening 11231 and a second opening 11232. The first opening 11231 is located on the first side surface 1121, and the second opening 11232 is located on the side of the second connection portion 112 facing the clamping block 113 and is connected to the first opening 11231. In the width direction of the docking piece 11, the size of the clamping block 113 is larger than the size of the second opening 11232, so that the clamping block 113 is limited in the clamping groove 1123 in the length direction of the docking piece 11. The shapes of the clamping block 113 and the clamping groove 1123 match each other. When the two docking pieces 11 are connected, the clamping block 113 of one docking piece 11 is clamped in the clamping groove 1123 of the other docking piece 11, and the connection between the clamping block 113 and the second connecting portion 112 is located at the second opening 11232 of the other docking piece 11.
[0042] The anti-theft pull tab 1 and the anti-theft zipper of the utility model respectively drive the two bases 2 to close the zipper tape through the two docking pieces 11, and then the clamping block 113 is clamped into the clamping groove 1123 of the other docking piece 11 through the first opening 11231 along the thickness direction of the second connecting portion 112, so as to realize the connection of the two docking pieces 11. The connection between the clamping block 113 and the second connecting portion 112 is located at the second opening 11232 of the other docking piece 11. In the width direction of the docking piece 11, the size of the clamping block 113 is smaller than that of the second connecting portion 112. The size of the second opening 11232 is such that the snap-in block 113 is limited in the snap-in groove 1123 in the length direction of the docking piece 11, so that the two docking pieces 11 cannot pull the two bases 2 to slide away from each other; if the two docking pieces 11 are to be separated, the snap-in block 113 needs to be taken out of the snap-in groove 1123 of the other docking piece 11 through the first opening 11231 of the other docking piece 11, which requires a certain amount of strength and the backpack will also have a certain reaction. If it is a thief, it is easy to sense. The anti-theft pull tab 1 and anti-theft zipper of the utility model achieve the anti-theft effect by detachably connecting the two docking pieces 11 in a specific direction.
[0043] Please refer to Figure 3 The clamping groove 1123 has a groove bottom wall 11233 opposite to the first opening 11231, and a limiting groove 1124 is arranged on the groove bottom wall 11233. The clamping block 113 has an inner surface 1131 that fits the groove bottom wall 11233, and a limiting block 1133 is arranged on the inner surface 1131. The shape of the limiting block 1133 matches the shape of the limiting groove 1124. When the two docking pieces 11 are connected, the limiting block 1133 of one docking piece 11 is clamped in the limiting groove 1124 of the other docking piece 11. Through the matching clamping of the limiting block 1133 and the limiting groove 1124, the two docking pieces 11 are connected more tightly. If the two docking pieces 11 are to be separated, more force is required, thereby enhancing the anti-theft effect.
[0044] Please refer to Figure 3 and Figure 4 The limiting groove 1124 passes through the second side surface 1122 and the groove bottom wall 11233 along the thickness direction of the second connecting portion 112. With this structure, the limiting groove 1124 can be made deeper, thereby increasing the contact area between the limiting block 1133 and the limiting groove 1124, making the two more firmly connected.
[0045] Please refer to Figure 3 The clamping block 113 and the clamping groove 1123, and the limiting block 1133 and the limiting groove 1124 are interference fit. Without human operation, the above structure makes it difficult for the clamping block 113 to be separated from the clamping groove 1123 and the limiting block 1133 to be separated from the limiting groove 1124, thereby preventing the two docking pieces 11 from automatically separating.
[0046] Please refer to Figure 3 The clamping groove 1123 includes a first wall 11234 and two second walls 11235. The first wall 11234 and the second opening 11232 are arranged opposite to each other in the length direction of the docking piece 11. The two second walls 11235 are arranged opposite to each other in the width direction of the docking piece 11. The first wall 11234 is straight and arranged along the width direction of the docking piece 11, and is connected between the two second walls 11235. In the width direction of the docking piece 11, the distance between the two second walls 11235 gradually decreases from the first wall 11234 to the second opening 11232. In the above structure, the clamping groove 1123 surrounded by the first wall 11234 and the two second walls 11235 is a trapezoid, which is easy to process.
[0047] Please refer to Figure 4 The clamping block 113 has an outer surface 1132. On the same docking piece 11, the outer surface 1132 is flush with the second side surface 1122. When two docking pieces 11 are connected, the outer surface 1132 is flush with the first side surface 1121 of the other docking piece 11. With the above structure, when two docking pieces 11 are connected, if the inner surface 1131 of the clamping block 113 contacts the groove bottom wall 11233, the two side surfaces of the anti-theft pull tab 1 are both flat, and it can be identified whether the two docking pieces 11 are connected in place.
[0048] Please refer to Figure 3 , please also refer to Figure 1 The docking piece 11 also includes a connecting piece 114, which is connected between the second connecting portion 112 and the clamping block 113. The clamping block 113 is connected to the middle position of the connecting piece 114 in the width direction of the docking piece 11. When the two docking pieces 11 are connected, the connecting pieces 114 of the two docking pieces 11 are parallel to each other, and the side of the connecting piece 114 connected to the clamping block 113 abuts against the second connecting portion 112 of the other docking piece 11. When the two docking pieces 11 need to be separated, the user can pinch the two connecting pieces 114 with both hands to move them away from each other, thereby driving the clamping block 113 to disengage from the clamping groove 1123, making it easier to separate the two docking pieces 11. When the two docking pieces 11 are connected, the connecting pieces 114 of the two docking pieces 11 are parallel to each other, and the side of the connecting piece 114 connected to the clamping block 113 abuts against the second connecting portion 112 of the other docking piece 11, so that the anti-theft pull tab 1 after the two docking pieces 11 are connected can have a better appearance consistency.
[0049] Please refer to Figure 3The second connecting portion 112, the connecting piece 114 and the clamping block 113 are made of plastic and are integrally formed. With the above structure, the second connecting portion 112 and the clamping block 113 have a certain elasticity, which facilitates the clamping block 113 to be clamped in the clamping groove 1123, and the limiting block 1133 to be clamped in the limiting groove 1124. The integrally formed structure makes the above structures firmly connected and easy to process.
[0050] The anti-theft pull tab 1 also includes a positioning sleeve, which is movable on one of the docking pieces 11. When the two docking pieces 11 are locked, the positioning sleeve is located at the locking portion of the two docking pieces 11. The positioning sleeve is used to cover the locking portion of the two docking pieces 11, which can prevent thieves from seeing the locking structure clearly, further improving the anti-theft effect. If the user wants to separate the two docking pieces 11, the movable sleeve is slid onto one of the docking pieces 11 to expose the locking portion.
[0051] The method of using the anti-theft zipper of the preferred embodiment of the utility model is as follows:
[0052] After the two docking pieces 11 drive the two bases 2 to close the zipper tape respectively, the snap-in block 113 is snapped into the snap-in groove 1123 of the other docking piece 11 through the first opening 11231 along the thickness direction of the second connecting portion 112, and the limiting block 1133 is snapped into the limiting groove 1124 of the other docking piece 11 at the same time, thereby realizing the connection between the two docking pieces 11. The connection between the snap-in block 113 and the second connecting portion 112 is located at the second opening 11232 of the other docking piece 11. In the width direction of the docking piece 11, the size of the snap-in block 113 is smaller than the size of the second opening 11232, so that the snap-in block 113 is limited to the snap-in groove 1123 in the length direction of the docking piece 11, so that the two docking pieces 11 cannot pull the two bases 2 to slide away from each other. If the two docking pieces 11 need to be separated, pinch the two connecting pieces 114 with both hands and move them away from each other, thereby driving the snap-fit block 113 to pass through the first opening 11231 of the other docking piece 11 and be taken out of the snap-fit groove 1123 of the other docking piece 11, and at the same time driving the limiting block 1133 to be taken out of the limiting groove 1124 of the other docking piece 11. This process requires a certain amount of strength and the backpack will also have a certain reaction. If it is done by a thief, it will be easily sensed.
[0053] This completes the method for using the anti-theft zipper of the preferred embodiment.
[0054] The anti-theft pull tab and anti-theft zipper of the utility model respectively drive the two bases to close the zipper belt through the two docking pieces, and then the clamping block is clamped into the clamping groove of the other docking piece through the first opening along the thickness direction of the second connecting part, so as to realize the connection of the two docking pieces. The connection between the clamping block and the second connecting part is located at the second opening of the other docking piece. In the width direction of the docking piece, the size of the clamping block is smaller than the size of the second opening, so that the clamping block is limited in the clamping groove in the length direction of the docking piece, so that the two docking pieces cannot pull the two bases to slide away from each other; if the two docking pieces are to be separated, the clamping block needs to be taken out from the clamping groove of the other docking piece through the first opening of the other docking piece. At this time, a certain amount of force is required, and the backpack will also have a certain reaction. If it is a thief's action, it is easy to sense. The anti-theft pull tab and anti-theft zipper of the utility model achieve the anti-theft effect through the detachable connection of the two docking pieces in a specific direction.
[0055] To sum up, although the present invention has been disclosed as above in the form of preferred embodiments, the protection scope of the present invention is not limited thereto, and any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the concept of the technical solution of the present invention, which should be covered by the protection scope of the present invention.
