[0035] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Please refer to Figs. 1 to 3 The present application provides a paper self-locking ribbon, comprising: a plug 1, a ribbon body 2 and a tail 3.

[0037] The plug 1, the ribbon body 2 and the tail 3 are integrally formed and are all made of paper material.

[0038] The plug 1 is arranged on one side of the ribbon body 2, and the tail 3 is arranged on the other side of the ribbon body 2.

[0039] A plurality of reverse tooth 21 structures are arranged on both sides of the ribbon body 2, and a clamping area 34 is arranged on the tail 3.

[0040] The paper self-locking ribbon has a locked state and an unlocked state. In the locked state, the plug 1 is inserted into the clamping area 34, and the reverse tooth 21 on the ribbon body 2 is clamped in the clamping area 34 to achieve locking. In the unlocked state, the reverse tooth 21 on the ribbon body 2 is separated from the clamping area 34.

[0041] First, the components in the embodiment will be described as follows:

[0042] The plug 1 is located on one side of the ribbon body 2 and is a key part for realizing the locking function of the ribbon. The plug 1 is wedge-shaped, and the cross-sectional area of the head end of the plug 1 is smaller than that of the tail end of the plug 1. Specifically, the head end of the plug 1 is narrower, and the tail end of the plug 1 is wider, so as to facilitate the quick insertion of the plug 1 into the clamping area. In the locked state, the plug 1 is inserted into the clamping area 34 on the tail 3 and tightly cooperates with the plurality of reverse tooth 21 structures on the ribbon body 2 and the clamping area 34 to realize the fixation and locking of the ribbon, thereby tightly fixing the article.

[0043] The band body 2 is made of paper material, which can ensure environmental protection and reduce costs. A plurality of reverse teeth 21 structures are arranged on both sides of the band body 2. The reverse teeth 21 structures are clamped with the clamping area on the tail part 3 after being clamped into the clamping area, thereby playing a clamping and fixing role in the locked state.

[0044] The band body 2 is the main part of the cable tie. By surrounding the article to be bound or packaged, and by the interaction of the reverse teeth 21 with the clamping area 34 on the tail part 3, the locking of the cable tie is achieved.

[0045] The tail part 3 is located on the other side of the band body 2. The shape of the tail part 3 is not limited in the present application and can be set according to actual conditions. The clamping area 34 is arranged on the tail part 3, which is the area where the plug-in tongue 1 is inserted and clamps the reverse tooth 21 structure. The clamping area 34 enables the band body 2 to be firmly clamped therein, thereby ensuring the stability of the cable tie.

[0046] The reverse tooth 21 structure is arranged on both sides of the band body 2. In the locked state, the reverse tooth 21 is clamped in the clamping area 34 of the tail part 3, preventing the cable tie from loosening or falling off. The reverse tooth 21 structure of the band body 2 can increase the binding force and stability of the cable tie, so that the band body 2 can be better clamped and fixed on the tail part 3, thereby enabling the cable tie to better fix the article.

[0047] The operation process of the paper self-locking cable tie will be introduced as follows:

[0048] When the cable tie needs to be locked on the article, first, the band body 2 is wrapped around the article and tightened. Then, the plug-in tongue 1 is inserted into the clamping area 34 on the tail part 3, and the plug-in tongue 1 is pulled, so that the band body 2 also enters the clamping area 34. When the pulling of the plug-in tongue 1 is stopped, the reverse tooth 21 on both sides of the band body 2 is clamped in the clamping area 34, forming a firm locking structure.

[0049] The advantages of this embodiment are as follows:

[0050] The reverse tooth 21 structure on the band body 2 cooperates with the clamping area 34 on the tail part 3 to achieve a self-locking function. When the article is tied, the cable tie is passed through the article, and then the plug-in tongue 1 is inserted into the clamping area 34 and tightened, which can automatically lock without the need for additional tools or complex operations, making it more convenient to use. The self-locking cable tie is made of paper material, which has better biodegradability than traditional plastic cable ties. After use, it can naturally degrade, reducing pollution to the environment, thereby meeting the needs of different application scenarios and having a wider range of applications.

[0051] In an alternative embodiment, the inverted tooth 21 is arranged in a slope shape 211 near one end of the plug 1, and is arranged in a hook shape 212 near one end of the tail 3.

[0052] In the embodiment of the present application, the slope shape 211 on the inverted tooth 21 enables the plug 1 to more smoothly slide through the clamping region during insertion into the clamping region 34 of the tail 3 after the band body 2 is wrapped around an article, effectively reducing the resistance during insertion, while the hook shape 212 on the inverted tooth 21 enables the inverted tooth 21 to more firmly hook the edge of the clamping region 34 after clamping into the clamping region 34 of the tail 3, thereby more easily completing the locking action.

[0053] The hook shape 212 on the inverted tooth 21 can more effectively resist falling off when subjected to external force, has a retreat-preventing effect, and ensures that the inverted tooth 21 is always tightly clamped in the clamping region 34 even if the cable tie is subjected to a greater pulling force or vibration, thereby preventing accidental unlocking of the cable tie.

[0054] In an alternative embodiment, the tail 3 is provided with a first through hole 31, a second through hole 33, and a lock tongue 32, the first through hole 31 and the second through hole 33 are communicated to form a placement region, and the lock tongue 32 is arranged in the placement region to form the clamping region 34.

[0055] In the embodiment of the present application, the tail 3 is provided with a first through hole 31 and a second through hole 33, the first through hole 31 and the second through hole 33 are communicated on the tail 3, and the two through holes together form a placement region in which the plug 1 is placed, i.e., when the lock tongue 32 is placed in the placement region, the placement region forms the corresponding clamping region 34.

[0056] The lock tongue 32 is located in the placement region formed by the communication of the first through hole 31 and the second through hole 33, and when the plug 1 is inserted into the lock tongue 32, the lock tongue 32 will be lifted up and clamped on the tongue body portion of the plug 1, thereby playing a retreat-preventing role.

[0057] Further, the vertical distance between the outer edges of the first through hole 31 and the second through hole 33 is less than the vertical distance between the outer edges of the inverted teeth 21 on both sides of the band body 2, so as to clamp the inverted teeth 21 structure on the band body 2 in the clamping region, specifically,

[0058] The vertical distance between the outer edges of the first through hole 31 and the second through hole 33 refers to the longest straight line distance between the outer edges of the two through holes in the width direction of the tail 3, while the vertical distance between the outer edges of the inverted teeth 21 on both sides of the band body 2 refers to the vertical distance between the outermost edges of the inverted teeth 21 on both sides of the band body 2.

[0059] Therefore, in practical application, when the reverse tooth 21 is inserted into the insertion area, the hook of the reverse tooth 21 is clamped by the edges of the first through hole 31 and the second through hole 33, so that the reverse tooth 21 cannot be pulled out of the clamping area, thereby ensuring that the cable tie can firmly fix the article in the locked state, and because the outer edge of the reverse tooth 21 exceeds the outer edge of the through hole of the tail 3, the cable tie is not easy to loosen or fall off even if an external force is applied, and the stability is high.

[0060] When the insertion tongue 1 is pulled to tighten the article to be tied, the corresponding reverse tooth 21 of the belt body 2 is clamped on the outer sides of the two through holes of the tail 3, and the locking tongue 32 in the clamping area is clamped to prevent the belt body 2 from retreating, and through the cooperation of the two, the locked state is ensured, so that the belt body 2 cannot be pulled out of the locking tongue 32.

[0061] In an optional embodiment, the outer edge of the reverse tooth 21 is provided in a rounded shape.

[0062] In the embodiment of the present application, the outer edge of the reverse tooth 21 is provided in a rounded shape, which can significantly reduce the friction and wear between the reverse tooth 21 and other components during contact and clamping, so that when the paper self-locking cable tie is used, whether it is fixed on the article or unlocked, the damage to the surface of the article can be reduced, the integrity of the article is maintained, and the user can be better protected during use to avoid injury to the user.

[0063] Further, the rounded shape of the reverse tooth 21 makes the reverse tooth 21 more smooth when inserted into the clamping area 34, reduces the resistance generated by the sharp edge, thereby reducing the force required by the user when using the cable tie, so that the user can lock the cable tie more easily without too much effort, thereby improving the user experience.

[0064] In an optional embodiment, the shape of the insertion tongue 1 is provided in a wedge shape, the tail end of the insertion tongue 1 is connected with the belt body 2, the cross-sectional area of the head end of the insertion tongue 1 is smaller than the cross-sectional area of the tail end of the insertion tongue 1, and the head end of the insertion tongue 1 is provided in a rounded shape.

[0065] In the embodiment of the present application, the wedge shape of the insertion tongue 1 means that the insertion tongue 1 gradually narrows from the tail end to the head end, forming an inclined slope, and the wedge shape makes the insertion tongue 1 more smoothly enter the clamping area 34 on the tail 3, reducing the resistance in the insertion process.

[0066] The head end of the insertion tongue 1 is provided in a rounded shape, which makes the insertion tongue 1 more smoothly transition when inserted into the clamping area 34, reducing the resistance encountered during insertion.

[0067] In an optional embodiment, the plurality of reverse teeth 21 on both sides of the belt body 2 are provided at equal intervals.

[0068] In the locking state, the inverted teeth 21 are clamped into the clamping area 34 of the tail 3, and the equidistantly arranged inverted teeth 21 can form continuous locking points, thereby increasing the stability of the cable tie in the locked state, and making it more difficult for the cable tie to be unlocked or loosened due to external force.

[0069] The equidistant arrangement of the inverted teeth 21 makes the locking process of the cable tie smoother, reduces the situation of jamming or difficulty in locking caused by uneven distribution of the inverted teeth 21, and makes the cable tie easier to operate and apply.

[0070] The paper material is raw kraft paper material, and the basis weight of the raw kraft paper material is 250g / m 2 -350g / m 2 The raw kraft paper is directly made of wood pulp without further processing, and the fiber structure is relatively complete, so it has high strength and tear resistance, meeting the requirements of the self-locking cable tie.

The body 2 is provided with a plurality of inverted tooth structures 21 on both sides, and the tail 3 is provided with a clamping area 34. The paper self-locking cable tie has a locked state and an unlocked state. In the locked state, the plug 1 is inserted into the clamping area 34, and the inverted teeth 21 on the body 2 are clamped in the clamping area 34 to achieve locking. In the unlocked state, the inverted teeth 21 on the body 2 are separated from the clamping area 34.

[0073] The hook shape 212 on the inverted tooth 21 can more effectively resist falling off when subjected to external force, has a retreat prevention effect, and can ensure that the inverted tooth 21 is always clamped in the clamping area 34 and cannot slide outwards, thereby preventing the cable tie from being accidentally unlocked.

[0074] The tail 3 is provided with a first through hole 31 and a second through hole 33, and the first through hole 31 and the second through hole 33 are communicated on the tail 3, and the two through holes together form a placement area in which the plug 1 is placed, that is, when the lock tongue 32 is placed in the placement area, the placement area forms the corresponding clamping area 34.

[0075] The lock tongue 32 is located in the placement area formed by the communication of the first through hole 31 and the second through hole 33, and when the plug 1 is inserted into the lock tongue 32, the lock tongue 32 will be lifted up and clamped in the tongue body part of the plug 1, thereby playing a retreat prevention effect.

[0076] Further, the vertical distance between the outer edges of the first and second through holes 31 and 33 is less than the vertical distance between the outer edges of the inverted teeth 21 on both sides of the band body 2, so as to realize the clamping of the inverted teeth 21 structure on the band body 2 in the clamping area. Specifically,

[0077] The vertical distance between the outer edges of the first and second through holes 31 and 33 refers to the longest straight line distance between the outer edges of the two through holes in the width direction of the tail 3, and the vertical distance between the outer edges of the inverted teeth 21 on both sides of the band body 2 refers to the vertical distance between the outermost edges of the inverted teeth 21 on both sides of the band body 2.
