Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a colored thread zipper. Background Art

[0002] A zipper is a common closing device and is widely used in various products such as clothing, bags, tents, etc. Traditional zippers are composed of two tapes with interlocking teeth on their edges, and a pulling component (usually called a slider) is used to realize the opening and closing functions. However, during use, especially during movement or under external force, the zipper sometimes accidentally opens by itself, resulting in the inability of clothes or bags to remain closed, bringing inconvenience to users. Although there are various types of zippers on the market currently, there are still deficiencies in preventing accidental opening caused by non-human factors. Therefore, it is of great practical significance to design a new type of zipper that can prevent the slider from moving in the opening direction under natural conditions, thereby avoiding accidental opening of the zipper caused by non-human factors. Content of the Utility Model

[0003] The utility model provides a colored thread zipper that can prevent the slider from moving in the opening direction under natural conditions, thereby avoiding the above problems existing in the prior art during use.

[0004] The technical solution of the utility model is realized as follows: A colored thread zipper includes cloth tapes and a slider. On the side edges of the two cloth tapes close to each other, reinforcing strips are fixedly connected, and the reinforcing strips extend along the length direction of the cloth tapes. A number of interlocking teeth are fixedly arranged on the two cloth tapes along the reinforcing strips. The slider is located between the two cloth tapes and is used to operate the interlocking teeth on the two cloth tapes to engage or separate. A limiting member is fixedly arranged between the two cloth tapes and is located below the lowermost interlocking teeth. Anti-opening mechanisms are arranged on the two cloth tapes near the upper interlocking teeth, and the anti-opening mechanisms are used to lock the slider that moves to this position.

[0005] Preferably, the anti-opening mechanisms on the two cloth tapes are arranged symmetrically left and right. The anti-opening mechanism includes a movable abutting head and an elastic mechanism for pushing the movable abutting head to press against the side of the slider.

[0006] Preferably, the elastic mechanism includes a spring. The anti-opening mechanism further includes a housing fixed on the cloth tape. An expansion cavity with an opening facing the slider is formed in the housing. One end of the movable abutting head is movably arranged in the expansion cavity, and the spring is located in the expansion cavity and is used to push the movable abutting head to press against the side of the slider.

[0007] Preferably, a limiting inner edge is integrally formed at the opening position of the telescopic cavity of the housing, and a limiting protrusion for abutting against the limiting inner edge is provided at one end of the movable abutting head located in the telescopic cavity.

[0008] Preferably, the left side and the right side of the pull head are symmetrically arranged and are both provided with an upper inclined guiding surface, a lower inclined guiding surface and a positioning notch. The upper inclined guiding surface, the lower inclined guiding surface and the positioning notch are connected in sequence from top to bottom. An arc-shaped transition is formed between the upper inclined guiding surface and the lower inclined guiding surface, and one side of the movable abutting head close to the pull head is arc-shaped.

[0009] Preferably, reinforcing cloths are sewn on both of the two cloth tapes at the position where the housing is located, and the housing is fixed on the reinforcing cloths.

[0010] Preferably, a plurality of reinforcing colored threads are sewn along the length direction of both of the two cloth tapes, and the reinforcing colored threads are sewn through the reinforcing cloths.

[0011] In summary, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing an anti-opening mechanism, after the user pulls the pull head to operate the interlocking teeth on the two cloth tapes to engage and close the zipper, the pull head is located at the position of the upper interlocking teeth, that is, just between the anti-opening mechanisms of the two cloth tapes. At this time, the anti-opening mechanisms on the left and right sides of the pull head lock the pull head that has moved to this position, so as to prevent the pull head from moving in the opening direction in the natural state and avoid the problem of accidental opening of the zipper caused by non-human factors.

[0013] 2. The anti-opening mechanism uses a spring to push the movable abutting head to press against the side surface of the pull head, so as to play a locking role. When the user needs to open the zipper through the pull head, only need to pull the pull head downward with a little force, then the movable abutting head can be pushed to compress the spring, so as to cancel the locking effect.

[0014] 3. The setting of the reinforcing cloth can prevent the cloth tape at the fixed position of the housing from being damaged due to long-term stress. The setting of the reinforcing colored threads can improve the connection strength between the reinforcing cloth and the cloth tape on the one hand, and can highlight the sewing effect visually on the other hand, which is fashionable and beautiful.

[0021] Embodiment:

[0022] As Figures 1 to 3 shown, the present utility model discloses a colored thread zipper, including a cloth tape 1 and a pull head 5. Both cloth tapes 1 are fixedly connected with ribbed strips 2 on the edges close to each other. The ribbed strips 2 are arranged along the length direction of the cloth tape 1, and a number of interlocking chain teeth 3 are fixedly arranged on both cloth tapes 1 along the ribbed strips 2. The pull head 5 is located between the two cloth tapes 1 and is used to operate the interlocking chain teeth 3 on the two cloth tapes 1 to engage or separate. In addition, a limiting member 4 is fixedly arranged between the two cloth tapes 1 and below the lowermost interlocking chain teeth 3. In order to lock the pull head 5 after closing the interlocking chain teeth 3 on both sides, anti-opening mechanisms are provided on both cloth tapes 1 at positions close to the upper interlocking chain teeth 3, and the anti-opening mechanisms are used to lock the pull head 5 that moves to this position.

[0023] Specifically, the anti-opening mechanisms on the two cloth tapes 1 are symmetrically arranged left and right. The anti-opening mechanism includes a movable abutting head 6 and an elastic mechanism for pushing the movable abutting head 6 to press against the side of the slider 5. The elastic mechanism includes a spring 7. The anti-opening mechanism also includes a housing 8 fixed on the cloth tape 1. An expansion cavity 81 with an opening facing the slider 5 is formed in the housing 8. One end of the movable abutting head 6 is movably arranged in the expansion cavity 81. The spring 7 is located in the expansion cavity 81 and is used to push the movable abutting head 6 to press against the side of the slider 5.

[0024] After the slider 5 of the present utility model closes the interlocking teeth 3 on the two cloth tapes 1, it is just located between the anti-opening mechanisms of the two cloth tapes 1, that is, between the two movable abutting heads 6. The two movable abutting heads 6 are pressed against the left and right sides of the slider 5 by the action of the spring 7, thus playing a locking role. When the user needs to open the zipper through the slider 5, only a little force is needed to pull the slider 5 downward, and then the movable abutting head 6 can be pushed to compress the spring 7 and retract into the expansion cavity 81 of the housing 8, thereby canceling the locking effect.

[0025] In order to limit the length of the movable abutting head 6 extending out of the housing 8, a limiting inner edge 82 is integrally formed at the opening position of the expansion cavity 81 of the housing 8. A limiting protrusion 61 for abutting against the limiting inner edge 82 is provided at one end of the movable abutting head 6 located in the expansion cavity 81.

[0026] More specifically, the left side and the right side of the slider 5 are symmetrically arranged and are both provided with an upper inclined guiding surface 51, a lower inclined guiding surface 52 and a positioning notch 53. The upper inclined guiding surface 51, the lower inclined guiding surface 52 and the positioning notch 53 are connected in sequence from top to bottom. The upper inclined guiding surface 51 and the lower inclined guiding surface 52 are in an arc-shaped transition. The setting of the upper inclined guiding surface 51 is convenient for the slider 5 to move upward, which is used to push the movable abutting head 6, and then the movable abutting head 6 passes through the lower inclined guiding surface 52 and enters the positioning notch 53. The setting of the positioning notch 53 can be beneficial for the movable abutting head 6 to lock the slider 5. The lower inclined guiding surface 52 is for the slider 5 to move downward to push the movable abutting head 6 to retract into the expansion cavity 81 when opening the zipper. It should also be noted that the side of the movable abutting head 6 close to the slider 5 is in an arc shape.

[0027] In addition, in order to further enhance the locking effect, a magnetic attraction sheet 54 is fixedly connected in the positioning notch 53 of the slider 5, and the movable abutting head 6 is made of a magnetizable metal material.

[0028] In order to prevent the cloth tape 1 at the fixed position of the housing 8 from being damaged due to long-term stress, reinforcing cloth 11 is sewn on both cloth tapes 1 at the position where the housing 8 is located. The housing 8 is fixed on the reinforcing cloth 11 by adhesion. It should be noted that the material of the cloth tape 1 is polyester fiber, and the material of the reinforcing cloth 11 is Kevlar.

[0029] In the present utility model, a plurality of reinforcing colored threads 12 are sewn along the length direction on both of the two cloth tapes 1. The reinforcing colored threads 12 are sewn through the reinforcing cloth 11. The arrangement of the reinforcing colored threads 12 can, on the one hand, improve the connection strength between the reinforcing cloth 11 and the cloth tape 1, and on the other hand, can visually highlight the sewing effect, being fashionable and beautiful.

[0030] At the same time, it should be pointed out that the terms used in the present utility model, such as: "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0031] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
