Description

Sliding chain and clothing

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on July 29, 2022, with application number 202221984342.8 and invention name “A Sliding Chain and Clothing”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of clothing accessories and clothing, in particular to a sliding chain and clothing. Background Art

[0003] Sliding chains generally consist of a mother component and a daughter component, and the relative sliding of the mother and daughter components is achieved through continuously arranged chain teeth. They are now widely used in clothing, packaging, pockets, tents, etc. Usually, the daughter teeth of the daughter component slide in the mother teeth of the mother component; for example, when used in the connection between clothes and hats, one component connects to the clothes and the other connects to the hat, so that the hat can easily rotate with the head.

[0004] For example, a Chinese patent application (publication number: CN114468483A) discloses a sliding chain that achieves smooth sliding by coordinating the shape and structure of a mother component, a child component, and the mother component teeth and the child component teeth. However, to ensure a good smooth sliding effect, this type of sliding chain needs to expose the mother component or the child component. Because the mother component and the child component are installed with the teeth spaced apart, they are prone to air and water leakage, which seriously affects the aesthetic effect of clothing.

[0005] In order to gain good sales in the market, clothing needs to be provided with a brim on the hat for shielding. Then, when the hat rotates, the brim rotates with the hat, and the brim will rub against the outer side of the mother teeth. As a result, when the daughter teeth and the mother teeth themselves have friction, the external friction is increased, which reduces the smoothness of the sliding chain when turning the head and is prone to noise. The hat is very close to the human ear and is in a closed channel between the hat, clothing and the brim, which makes the wearer very uncomfortable when turning his head.

[0006] In summary, existing sliding chains and clothing face the problems of large rotational friction and loud noise. Therefore, based on this situation, a sliding chain and clothing need to be designed.

[0007] Summary of the Invention

[0040] The following is a further description of the embodiments of the present application with reference to the accompanying drawings:

[0041] A sliding chain includes a mother component 100 and a subcomponent component 200, wherein the mother component 100 includes a mother base belt 110 and mother teeth 120 spaced apart from each other on the mother base belt 110, wherein the mother teeth 120 are formed with a tooth inner cavity 130 and a main sliding portion 140, wherein the plurality of tooth inner cavities 130 and the main sliding portion 140 form a slideway, and the subcomponent component 200 includes a subcomponent base belt 210 and subcomponent teeth 220 spaced apart from each other on the subcomponent base belt 210; that is, the mother component 100 and the subcomponent component 200 sliding connection, multiple mother teeth 120 are arranged in sequence on the mother base belt 110 to form a slide rail, the mother assembly 100 also includes a tooth cavity 130 and a main sliding part 140 of the mother tooth 120, multiple tooth cavities 130 and the main sliding part 140 cooperate in sequence to form a slide, the sub-component teeth 220 are arranged in sequence on the sub-component base belt 210, one end of the sub-component tooth 220 slides in the slide, and the other end is connected to the sub-component base belt 210 to be sewn on the clothing.

[0042] The mother tooth 120 includes a mother base 121 and a tooth arm 122. The mother base 121 is connected to the mother base belt 110. The tooth arm 122 is arranged at both ends of the mother base 121. The tooth arm 122 includes a base 122a and an arm 122b connected to each other. The base 122a is connected to the mother base 121. The arm 122b of the tooth arm 122 at one end extends toward the other tooth arm 122 to form a tooth cavity 130 and a main sliding portion 140. Specifically, as shown in FIG. 2, the tooth arm is arranged on the upper side of the mother base 121. 122, the mother part base 121 and the tooth arm part 122 are integrally formed, the front and rear sides of the mother part base 121 are connected to the mother part base band 110, the tooth arm part 122 includes a base 122a connected to the mother part base 121, and an arm part 122b on the upper side of the base 122a, the base 122a is connected to the front end of the mother part base 121, the arm part 122b is connected to the base 122a, and extends to the rear end of the mother part base 121, thereby forming a tooth inner cavity 130 and a main sliding part 140 between the arm part 122b and the mother part base 121.

[0043] As shown in Figure 2, the arms 122b at the front ends of the front and rear ends of the upper side of the mother part base 121 extend toward the rear end, and the arms 122b at the rear end extend forward, so that the tooth arm parts 122 at both ends of the mother part base 121 form an encircling trend, and the mother part base 121 is symmetrical as a whole; the grooves left between the arms 122b are the main sliding parts 140, and the tooth arm parts 122 and the mother part base 121 are enclosed to form a tooth cavity 130. It should be noted that the direction plane of the main sliding part 140 to the tooth cavity 130 is at a certain angle to the mother part base band 110, and is preferably perpendicular to the plane where the mother part base band 110 is located.

[0044] When the main sliding portion 140 is perpendicular to the plane of the mother base belt 110 in the direction of the tooth inner cavity 130, it can ensure that after the mother base belt 110 is sewn on the clothes, the opening of the main sliding portion 140 is horizontal, that is, at this time the connecting portion 222 is horizontal. Based on the existing technology, such as the Chinese patent application (publication number: CN114468483A), a sliding chain is disclosed, which discloses a traditional sliding chain method with a connecting portion 222 to solve the technical problem of large friction at the connection position of the traditional main sliding portion 140. Therefore, through the cooperation between the connecting portion 222 and the main sliding portion 140, a good smooth effect can be achieved. However, in this embodiment, the sub-assembly 200 is connected to the hat. After the person wears the hat, the sub-assembly 200 (specifically The tooth portion 223 of the sub-component tooth 220 will give the mother-component tooth 120 a force toward the hat (upward when worn), so the tooth portion 223 will rub against the main sliding portion 140 and the side of the mother-component tooth 120 (including the side wall of the main sliding portion 140). In this technical solution, when the sub-component tooth 220 is subjected to an upward force, the tooth portion 223 cooperates with the main sliding portion 140 through the connecting portion 222, and the tooth portion 223 will not rub against the main sliding portion 140, which can reduce the friction between the tooth portion 223 and the mother-component tooth 120 on the side wall of the main sliding portion 140. Therefore, only the tooth portion 223 and the side of the mother-component tooth 120 (due to the distance between the mother-component teeth 120) remain to rub, thereby further improving the smoothness of the zipper.

[0045] The sub-component tooth 220 includes a tooth portion 223, a connecting portion 222, and a sub-component base 221. The sub-component base 221 is connected to the sub-component base strip 210. The tooth portion 223 is adapted to the tooth inner cavity 130, and the connecting portion 222 is adapted to the main slide 140, so that the tooth portion 223 slides along the sequentially arranged tooth inner cavities 130. The sub-component base 221 covers the side of the arm portion 122b of the main slide 140. In other words, the sub-component tooth 220 includes the sub-component base 221, the connecting portion 222, and the tooth portion 223. The tooth portion 223 slides within the tooth inner cavity 130. The cross-section of the tooth portion 223 is larger than that of the main slide 140 to ensure that the sub-component tooth 220 does not directly separate from the mother component tooth 120. The connecting portion 222 slides within the main slide 140, and the sub-component base 221 is connected to the sub-component base strip 210.

[0046] Specifically, as shown in FIG10 , the sub-assembly tooth 220 includes a sub-assembly base 221, a connecting portion 222, and a tooth portion 223. The upper and lower sides of the sub-assembly base 221 are connected to the sub-assembly base belt 210. The connecting portion 222 is perpendicular to the sub-assembly base 221. The sub-assembly base 221, the connecting portion 222, and the tooth portion 223 are arranged in an "I" shape. The connecting portion 222 slides within the main sliding portion 140 and is sized to match the main sliding portion 140. It should be noted that the sub-assembly base 221 extends vertically, obstructing the right side of the mother-assembly tooth 120. In other words, the left side of the sub-assembly base 221 is slidably connected to the right side of the mother-assembly tooth 120. By connecting to the sub-assembly base 221 on the right side of the mother-assembly tooth 120, the sub-assembly base 221 replaces the edge of the fabric in friction with the mother-assembly tooth 120, greatly reducing the total friction, effectively improving the overall smoothness, and reducing friction noise.

[0047] In addition, in another embodiment, the direction of the main sliding portion 140 toward the mother component base 121 is perpendicular to the plane where the mother component base tape 110 is located, and the adjacent surfaces of the sub-component base 221 and the mother component base 121 are both formed with arc surfaces.

[0048] As shown in Figure 10, the upper and lower sides of the mother tooth 120 are connected to the mother base band 110, and the main sliding part 140 extends toward the tooth inner cavity 130, and its extension line is perpendicular to the plane where the mother base band 110 is located, thereby forming a vertically arranged mother tooth 120, and the opening of the main sliding part 140 is in the horizontal direction. The upper and lower sides of the sub-component base 221 are connected to the sub-component base band 210, and the mother base band 110 is parallel to the sub-component base band 210. The right side of the mother tooth 120 forms a gradual folding surface or arc surface, and the rightmost side of the mother tooth 120 forms a smaller contact surface, and the left side of the sub-component base 221 forms an arc surface, and the middle position of the arc surface is a protruding position, thereby reducing the contact surface between the mother tooth 120 and the sub-component base 221.

[0049] In this connection mode, the sub-component base band 210 is directly connected to the hat, and the lower edge of the hat forms the edge in the prior art, so there is no need to add an additional edge to cover the mother component teeth 120, which has a good visual effect and will not let in air or leak water, making the sealing better.

[0050] In another embodiment, the sub-assembly base 221 is formed with wings 220a that extend in the direction of extension of the mother-assembly tooth 120. Specifically, as shown in FIG10 , the sub-assembly base 221 is formed with wings 220a in the vertical direction, so that the total vertical length of the sub-assembly base 221 is substantially the same as that of the mother-assembly base 121. This allows the sub-assembly base 221 to completely surround the open end of the main sliding portion 140 of the mother-assembly tooth 120, thereby providing a smooth and sleek feel.

[0051] In another embodiment, the tooth arms 122 at both ends of the female component base 121 are symmetrically arranged. Specifically, as shown in FIG10 , the central axis of the tooth cavity 130 and the main sliding portion 140 coincides with the central axis of the female component tooth 120, thereby ensuring that the connecting portion 222 is always horizontal, facilitating movement of the tooth portion 223 and the connecting portion 222 when the hat is moved.

[0052] In addition, in another embodiment, a limiting tooth 410 is also included. The limiting tooth 410 is arranged in the queue of the sub-component teeth 220 and is arranged at intervals. A protrusion 420 is provided at one end of the limiting tooth 410 to reduce the contact area between the adjacent sub-component teeth 220 and the mother tooth 120 of the limiting tooth 410.

[0053] The mother part base band 110 is also connected to the first limiting member 300, which is arranged at intervals in the mother part teeth 120 queue so that the mother part teeth 120 form a slide. At the same time, the first limiting members 300 at both ends of the slide limit the sub-part teeth 220 to prevent the sub-part assembly 200 from separating from the mother part assembly 100.

[0054] It includes more than one second limiting member 400, and the second limiting members 400 are arranged at intervals in the queue of the sub-component teeth 220. That is, in a single row of the sub-component teeth 220 queue, there are sub-component teeth 220 on the left and right sides of at least two second limiting members 400. The second limiting member 400 is connected to the sub-component base band 210, and the sub-component base band 210 drives the sub-component teeth 220 and the second limiting member 400 to move together.

[0055] Under the cooperation of the first limiting member 300 and the second limiting member 400, the subassembly 200 slides in the slideway formed by the mother teeth 120 between the two first limiting members 300. When the subassembly 200 slides to the first position, the first limiting member 300 and the second limiting member 400 abut against each other, so that the subassembly 200 is restricted from sliding. In the first position, the subassembly teeth 220 on one side of the second limiting member 400 are in the slideway, and the subassembly teeth 220 on the other side of the second limiting member 400 are outside the slideway. In the second position, the subassembly teeth 220 on one side of the other second limiting member 400 are in the slideway, and the subassembly teeth 220 on the other side are outside the slideway.

[0056] As shown in Figure 1, the mother component 100 includes mother teeth 120 and two mother base belts 110. In the left and right directions, multiple mother teeth 120 are arranged in a single row between the two mother base belts 110, and a certain distance is left between each two mother teeth 120. The edge of the mother base belt 110 forms a rib 111, and the mother teeth 120 are arranged on the rib 111. This connection structure has been disclosed in the application with publication number CN215958629U and will not be repeated here. In other embodiments, it can also include a mother base belt 110, and the mother teeth 120 are connected to a mother base belt 110.

[0057] As shown in Figure 2, the front and rear sides of each mother tooth 120 are connected to the mother base belt 110, and the tooth inner cavity 130 passes through the mother tooth 120 in the left and right directions. The main sliding part 140 extends upward from the tooth inner cavity 130 and passes through the mother tooth 120. The main sliding part 140 is smaller than the diameter of the tooth inner cavity 130 and plays a limiting role. Referring to Figure 1, multiple mother teeth 120 arranged in sequence, that is, multiple tooth inner cavities 130 and the main sliding part 140 arranged in sequence form a left and right slideway to facilitate the sliding of the sub-component teeth 220.

[0058] As shown in Figure 3, the sub-component assembly 200 includes a sub-component tooth 220 and two sub-component base belts 210. In the left and right directions, multiple sub-component teeth 220 are arranged in a single row between the two sub-component base belts 210, and a certain distance is left between every two sub-component teeth 220. A rib 111 is formed on the edge of the sub-component base belt 210, and the sub-component tooth 220 is arranged on the rib 111. As shown in Figure 4, the sub-component tooth 220 includes a sub-component base 221, a connecting portion 222 and a tooth portion 223. The tooth portion 223 slides in the tooth inner cavity 130. The cross-section of the tooth portion 223 is larger than the main sliding portion 140 to ensure that the sub-component tooth 220 will not directly detach from the mother tooth 120. The connecting portion 222 slides in the main sliding portion 140, and the sub-component base 221 is connected to the sub-component base belt 210.

[0059] As shown in FIG1 , the first limiting member 300 is disposed at the left and right ends of the array of the mother tooth 120. Referring to FIG9 , the first limiting member 300 includes a limiting seat 310 and an elastic member 320. Taking the left first limiting member 300 and the second limiting member 400 as an example, the right vertical surface of the elastic member 320 is higher than the bottom surface of the slideway of the mother tooth 120, and the upper surface of the elastic member 320 is not higher than the lower surface of the child tooth 220. Thus, the child tooth 220 slides directly out of the first limiting member 300a on the left side of the slideway, and the lower surface of the second limiting member 400a is lower than the upper surface of the right side of the elastic member 320.

[0060] In the first position, the left side of the second limiting member 400a abuts against the right side of the first limiting member 300a, thereby limiting the sub-assembly 200 from further moving leftward. At this time, the sub-assembly tooth 220 on the left side of the second limiting member 400a is already located outside the slideway, and the sub-assembly tooth 220 on the right side of the second limiting member 400a is located inside the slideway.

[0061] In the second position, the right side of the second limiting member 400b abuts against the left side of the first limiting member 300b, and the first limiting member 300b limits the mechanical movement of the sub-component assembly 200 to the right. At this time, the right side of the second limiting member 400b is already outside the slide, and the sub-component tooth 220 on the left side of the second limiting member 400b is inside the slide.

[0062] As shown in Figure 4, the sub-component tooth 220 queue is arranged in the left and right directions, and the second limit member 400a and the second limit member 400b are symmetrically arranged in the sub-component tooth 220 queue. In this embodiment, the total length of the mother component tooth 120 queue is 52 cm, the total length of the sub-component tooth 220 queue is 52 cm, the total length of the sub-component tooth 220 queue on the left side of the second limit member 400a is 7 cm, and the total length of the sub-component tooth 220 queue on the right side of the second limit member 400b is 7 cm.

[0063] The limiting seat body 310 is connected to the elastic member 320 . The elastic member 320 is located at both ends of the slideway formed by the female teeth 120 . The elastic member 320 abuts against the second limiting member 400 to limit the sub-assembly 200 .

[0064] The limiting teeth 410 of the second limiting component 400 are connected to the sub-component base band 210 in a row with the sub-component teeth 220, and a protrusion 420 is formed at one end of the limiting tooth 410, so that one end of the limiting tooth 410 protrudes from the sub-component teeth 220, and the protrusion 420 abuts against the elastic component 320, thereby achieving the limitation of the sub-component assembly 200.

[0065] As shown in Figure 10, the protrusion 420 of the limiting tooth 410 extends toward the left side of the tooth inner cavity 130. It can be understood that the protrusion 420 of the limiting tooth 410 reduces the contact area between the adjacent sub-component teeth 220 and the mother component teeth 120, thereby reducing the total contact area of ​​the sub-component tooth 220 queue, and thereby reducing the total friction probability.

[0066] As shown in FIG. 4 , the array of limiting teeth 410 is formed on the array of sub-component teeth 220 and can be arranged at the left and right ends of the array of sub-component teeth 220 .

[0067] The surface of the convex portion 420 in contact with the tooth inner cavity 130 is an arc surface to reduce friction. Specifically, as shown in FIG3 , the four peripheral edges of the convex portion 420 are chamfered in an arc shape. Similarly, the four peripheral edges of the tooth portion 223 of the sub-component tooth 220 are chamfered in an arc shape. As shown in FIG4 , the front and rear edge corners of the convex portion 420 are arc-shaped, and the front and rear edge corners of the tooth portion 223 of the sub-component tooth 220 are also arc-shaped.

[0068] The elastic member 320 blocks both ends of the slide. When in the first position or the second position, the protrusion 420 of the second limiting member 400 abuts against the elastic member 320 to prevent the sub-assembly 200 from separating from the mother assembly 100. However, the elastic member 320 itself has the ability to deform and will deform when subjected to a certain stress. That is to say, when the second limiting member 400 gives the elastic member 320 a force that exceeds its own deformation, the limiting tooth 410 can separate from the slide and the limiting base.

[0069] By setting the elastic member 320 in the first limit member 300, the second elastic member 320 can be detached from the slide and the limit base, that is, the sub-component assembly 200 can be detached from the mother component 100, and the assembly and disassembly method is simple and effective, which is conducive to improving production efficiency and is also convenient for users to operate.

[0070] As shown in FIG1 , the upper and lower ends of the limiting seat body 310 are connected to the mother base belt 110 and are arranged in a row with the mother teeth 120. A certain distance is left between the limiting seat body 310 and the adjacent mother teeth 120. As shown in FIG6 , a limiting inner cavity 330 is formed in the limiting seat body 310 along the left and right directions. The limiting inner cavity 330 penetrates the limiting seat body 310 in the left and right directions. The limiting inner cavity 330 penetrates the limiting seat body 310 upwardly to form an auxiliary sliding portion 340 extending in the left and right directions. The diameter of the limiting inner cavity 330 is larger than the diameter of the auxiliary sliding portion 340, which prevents the tooth portion 223 from sliding out of the auxiliary sliding portion. Part 340 is disengaged, and the elastic member 320 is arranged in the limiting seat body 310 and is connected to the limiting seat body 310. The elastic member 320 divides the limiting inner cavity 330 into an upper cavity portion 331 and a lower cavity portion 332. The upper cavity portion 331 is communicated with the auxiliary sliding portion 340. Both sides of the sub-component base 221 are connected to the sub-component base belt 210, so that the stability of the overall structure of the sliding chain is better. The connecting portion 222 slides out of the main sliding portion 140 and enters the auxiliary sliding portion 340. The tooth portion 223 of the sub-component tooth 220 slides out of the slideway and enters the limiting inner cavity 330, and then separates from the limiting base from the limiting inner cavity 330.

[0071] As shown in FIG6 , the elastic member 320 includes an elastic sheet 321, which is disposed in the limiting inner cavity 330. The elastic sheet 321 and the limiting seat body 310 are integrally formed. The elastic sheet 321 divides the limiting inner cavity 330 into an upper cavity portion 331 and a lower cavity portion 332. As shown in FIG7 , the limiting seat body 310 extends in the left-right direction, and the elastic sheet 321 extends in the left-right direction. The right end of the elastic sheet 321 is at the right end of the limiting seat body 310. The right end of the limiting seat body 310 protrudes to the right to form a receiving portion 350 to reduce the distance between the elastic sheet 321 and the right-side female component tooth 120, as shown in FIG8 The upper surface of the elastic sheet 321 forms a first inclined surface 322 which increases from left to right. The first inclined surface 322 facilitates the limiting tooth 410 to enter the slideway, and also facilitates the limiting tooth 410 to quickly slide out of the limiting inner cavity 330 after deforming the elastic member 320; as shown in FIG8 , the elastic sheet 321 extends in the left and right directions, and the left end of the elastic sheet 321 leaves a distance of 1 / 4-1 / 3 from the left side of the limiting seat body 310. The vertical surface of the right side of the elastic sheet 321 is thicker, and the upper side surface of the right end of the elastic sheet 321 is higher than the bottom surface of the tooth inner cavity 130, and the lower side surface of the right end of the elastic sheet 321 is lower than the bottom surface of the tooth inner cavity 130.

[0072] The limiting teeth 410 are the sub-component teeth 220, and the protrusion 420 is formed on the second inclined surface 421 along the extension direction of the sub-component baseband 210. Specifically, as shown in Figure 4, the limiting teeth 410 are arranged in the sub-component teeth 220 array, and the upper surface of the limiting teeth 410 forms the second inclined surface 421. The second inclined surface 421 gradually decreases from the end of the sub-component baseband 210 to the middle position of the sub-component baseband 210. The first inclined surface 322 cooperates with the second inclined surface 421 to facilitate the installation of the sub-component baseband 210 into the motherboard baseband 110. When the sub-component baseband 210 is separated from the motherboard baseband 110, the required stress is the same as that without the inclined surface, thereby improving the operating experience.

[0073] As shown in FIG4 , the sub-component teeth 220 array on the left side of the second limiting member 400a is the first section 230a, the sub-component teeth 220 array on the right side of the second limiting member 400b is the first section 230b, and the sub-component teeth 220 array between the two second limiting members 400 is the second section 240;

[0074] As shown in Figure 8, the limiting wall 311 of the limiting tooth 410 extending in the left and right directions is the same length as the left and right extension direction of the limiting seat body 310. As shown in Figure 4, the tooth portion 223 extends in the left and right directions, and the ratio of the length of the limiting wall 311 of the limiting seat body 310 to the left and right extension length of the tooth portion 223 is 1.2. The interval between the tooth portions 223 of each two adjacent sub-component teeth 220 is 0.5 mm. This proportion ensures that when the sub-component teeth 220 of the first section 230 slide into the slide, the limiting seat body 310 will not enter the gap between the adjacent sub-component teeth 220, thereby ensuring smoothness.

[0075] In other embodiments, the ratio of the length of the limiting wall 311 of the limiting seat body 310 to the left-right extension length of the tooth portion 223 is 1.3, 1.4, 1.5, or 1.6, and the spacing between the tooth portions 223 of each two adjacent sub-component teeth 220 is 0.5 mm, 0.45 mm, 0.4 mm, 0.35 mm, 0.3 mm, 0.25 mm, or 0.2 mm. Each embodiment may be any combination of the above values.

[0076] In other embodiments, the ratio of the length of the limiting wall 311 of the limiting seat body 310 to the left-right extension length of the tooth portion 223 is 1.5, and the interval between the tooth portions 223 of every two adjacent sub-component teeth 220 is 0.3 mm.

[0077] The sub-component teeth 220 in the first section 230 are installed on the sub-component base band 210 at equal distances, and the sub-component teeth 220 in the second section 240 are installed on the sub-component base band 210 at equal distances. The distance between the sub-component teeth 220 in the first section 230 is smaller than the distance between adjacent sub-component teeth 220 in the second section 240. The distance between the sub-component teeth 220 in the second section 240 is 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, and 1.4mm. By setting the second section 240 with a large spacing, the sub-component assembly 200 can be bent to a greater extent at the second section 240 position, which is convenient for stacking and storage.

[0078] In addition, in another embodiment, the limiting tooth 410 is a sub-component tooth 220, and the protrusion 420 is spaced apart in the tooth array of the sub-component tooth 220 to form a spaced apart second limiting component 400, and the total length of the protrusion 420, the tooth portion 223 and the connecting portion 222 is greater than the length from the opening of the main sliding portion 140 to the inner wall of the tooth cavity 130.

[0079] The limiting tooth 410 is a sub-component tooth 220, and the second limiting member 400 is a sub-component tooth 220 formed with a convex portion 420 on one side. That is, in the sub-component tooth 220 array, the interval sub-component tooth 220 is formed with a convex portion 420. Specifically, as shown in FIG4 , the limiting tooth 410 includes a sub-component base 221, a connecting portion 222 and a tooth portion 223, and the shape and position correspond to the sub-component tooth 220 array. The upper side of the tooth portion 223 of the limiting tooth 410 is formed with a convex portion 420. Referring to FIG5 , the cross-sectional area of ​​the tooth portion 223 of the sub-component tooth 220 decreases from bottom to top, and the four sides are chamfered. The upper side of the tooth portion 223 of the limiting tooth 410 protrudes upward to form a convex portion 420, and any surface of the convex portion 420 is a curved surface.

[0080] It should be noted that, as shown in Figure 10, the total length of the protrusion 420, the tooth portion 223 and the connecting portion 222 is greater than the length from the opening of the main sliding portion 140 to the inner wall of the tooth cavity 130, that is, the distance from the contact point of the leftmost side of the protrusion 420 with the mother tooth 120 to the sub-component base 221 is greater than the distance from the contact point of the tooth cavity 130 with the protrusion 420 to the position of the main sliding portion 140 on the right side of the mother tooth 120, that is, in the process of sliding between the mother tooth 120 and the sub-component tooth 220, the left side of the sub-component base 221 will not contact the right side of the mother tooth 120, thereby further reducing the friction force, and the structural connection stability is achieved by the cooperation between the connecting portion 222 and the main sliding portion 140 to achieve a stable connection effect.

[0081] In addition, in another embodiment, the tooth inner cavity 130 includes a first cavity portion 131 and a second cavity portion 132, the first cavity portion 131 is communicated with the second cavity portion 132, the first cavity portion 131 is adapted to the limiting tooth 410 and the sub-component tooth 220, and the second cavity portion 132 is adapted to the protrusion 420, so that the limiting tooth 410 and the sub-component tooth 220 slide in the first cavity portion 131 arranged in sequence, and the protrusion 420 slides in the second cavity portion 132 arranged in sequence. As shown in FIG10 , the mother tooth 120 is formed with two horizontal walls on the sliding portion, and the upper and lower walls of the first cavity 131 are both arc-shaped. When the child tooth 220 is located in the mother tooth 120, the upper and lower thicknesses of the connecting portion 222 and the spacing between the mother tooth 120 in the upper and lower directions of the sliding portion are different. The difference is not less than 0.2 mm and not more than 0.5 mm. In this embodiment, 0.3 mm is used. In other embodiments, it can also be 0.25 mm, 2.35 mm, 0.4 mm, or 0.45 mm. Similarly, in the same vertical plane, the left and right thicknesses of the tooth portion 223 are different from the left and right thicknesses of the tooth portion 223. There is a difference in the distance between the upper and lower walls of the first cavity 131, and the difference is not less than 0.2mm and not more than 0.8mm. In this embodiment, 0.4mm is used. In other embodiments, 0.3mm, 0.5mm, 0.6mm, and 0.7mm can also be used. By designing the sub-component teeth 220, the sliding portion, and the tooth cavity size, and cooperating with the arc surface of the sub-component teeth 220 in the slide, the movable range of the sub-component teeth 220 is locked to prevent the protrusion 420 from entering the first cavity 131 and avoid the sub-component teeth 220 from having an excessively large movable range, thereby ensuring good smoothness.

[0082] In addition, in another embodiment, the edge of the tooth portion 223 is arc-shaped, and a first plane 223a is formed on the side of the tooth portion 223 facing the main sliding portion 140. A second plane 120a adapted to the first plane 223a is formed at the connection between the tooth inner cavity 130 and the main sliding portion 140. Specifically, as shown in FIG10 , the protrusion 420 is formed on the side of the tooth portion 223 facing away from the main sliding portion 140. Referring to FIG10 , the main sliding portion 140 of the mother tooth 120 faces right, and the protrusion 420 is formed on the left side of the tooth portion 223. The cross-section of the protrusion 420 gradually decreases from the tooth portion 223 to the left in an arc shape, so that the left side of the protrusion 420 is linearly connected to the left side of the tooth inner cavity 130. The left side of the tooth portion 223 is a plane, which is connected to the plane gap of the elastic sheet 321. As shown in FIG10 , the tooth inner cavity 130 includes a first cavity portion 131 and a second cavity portion 132. The first cavity portion 131 is communicated with the main sliding portion 140. The upper and lower side walls of the first cavity portion 131 are gradually curved, and the second cavity portion 132 is gradually expanded from left to right and connected to the first cavity portion 131, thereby making the side of the sub-component tooth 220 linearly connected to the wall of the first cavity portion 131, and the side of the protrusion 420 is linearly connected to the wall of the second cavity portion 132.

[0083] The upper and lower side surfaces of the tooth portion 223 are both arc surfaces, which cooperate with the arc surface of the first cavity portion 131. The right side of the tooth portion 223 forms a first plane 223a, and the position where the tooth inner cavity 130 cooperates with the first plane 223a forms a second plane 120a. Through the cooperation between the first plane 223a and the second plane 120a and the cooperation between the tooth portion 223 and the arc surface of the first cavity portion 131, the sub-component tooth 220 is subjected to force, and the plane and the arc surface cooperate to form a good connection relationship, thereby ensuring the smoothness of the sliding chain.

[0084] A garment includes a sliding chain, and also includes a first garment and a second garment. The first garment is connected to a mother baseband 110, and the second garment is connected to a child baseband 210, so that the first and second garments can slide relative to each other. Specifically, the garment is connected to the mother baseband 110, and the hat is connected to the child baseband 210. As shown in Figure 10, the mother assembly 100 and the child assembly 200 are in the same plane, allowing the garment and the hat to slide relative to each other.

[0085] It should be emphasized that the embodiments described in this application are illustrative rather than restrictive. Therefore, this application is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of this application also fall within the scope of protection of this application.
