[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific examples are given below.
[0026] Please see Figures 1-4 This utility model provides a zipper tooth anti-detachment reinforcement structure, including a zipper tape 1; a zipper tooth body 11 is slidably connected to the middle of the zipper tape 1; an extension plate 12 is fixedly connected to the bottom plate of the zipper tooth body 11; two sleeves 13 are fixedly connected to both sides of the extension plate 12; a spring 14 is fixedly connected to the middle of the sleeve 13; a sleeve rod 15 is fixedly connected to one end of the spring 14; the sleeve rod 15 is slidably connected to the sleeve 13; and a spreading plate 16 is fixedly connected to one end of the sleeve rod 15. During operation, the zipper tooth body 11 is first pulled, and the zipper tooth body 11 slides on the zipper tape 1. During this process, the spreading plate 16 will... The lining fabric near zipper tooth 11 is extended to reduce wrinkles in the lining fabric when the zipper tooth body 11 approaches, preventing the zipper tooth body 11 from getting stuck in the lining fabric with the zipper tape 1, causing the zipper tooth body 11 to jam. When the zipper tooth body 11 reaches the end of the zipper tape 1, the unfolding plate 16 will be obstructed at the end and move backward, the sleeve 15 will slide inside the sleeve 13, and the spring 14 will be compressed. This will not affect the tight connection between the zipper tooth body 11 and the zipper tape 1. By setting the unfolding plate 16 to flatten the lining fabric around the zipper tooth body 11 during operation, the jamming phenomenon of the zipper tooth body 11 is reduced, allowing the zipper tooth body 11 to run smoothly on the zipper tape 1.
[0027] Furthermore, such as Figure 2 and Figure 3 As shown, a positioning rod 2 is fixedly connected to the middle of the flat panel 16; wax blocks 21 are fixedly provided on both sides of the positioning rod 2; during operation, the positioning rod 2 is at the front end of the zipper tooth body 11, in the middle of the unclosed zipper strip 1. When the zipper tooth body 11 is running, the positioning rod 2 will also shuttle through the middle of the zipper strip 1, and the wax blocks 21 will contact the zipper strip 1 on both sides to apply wax to it. This is more conducive to the smooth sliding of the zipper tooth body 11 and reduces the friction between the zipper tooth body 11 and the zipper strip 1 that causes jamming; by setting the positioning rod 2 and the wax blocks 21, the zipper strip 1 is waxed while it is running, which increases the lubrication between the zipper strip 1 and the zipper tooth body 11 and reduces the occurrence of jamming between the zipper strip 1 and the zipper tooth body 11.
[0028] Furthermore, such as Figure 3 As shown, the positioning rod 2 is provided with sponge strips 3 on both sides; the sponge strips 3 are fixedly connected to the unfolding plate 16; during operation, the unfolding plate 16 moves with the zipper tooth body 11. The unfolding plate 16 moves at the bottom of the zipper belt 1, and the sponge strips 3 will contact the bottom of the zipper belt 1 to wipe its surface. The bottom of the zipper belt 1 is on the inside, which will obstruct the field of vision and make it difficult to observe the debris attached to its surface. The sponge strips 3 clean it to reduce the contamination of debris, which may cause the zipper belt 1 and the zipper tooth body 11 to jam when they are engaged.
[0029] Furthermore, such as Figure 5 As shown, a stop block 4 is fixedly connected to the end of the zipper tape 1; a groove 41 is provided in the middle of the stop block 4; during operation, when the unfolding plate 16 is at the end of the zipper tape 1, it is obstructed by the stop block 4 and simultaneously pushed and pulled by the zipper tooth body 11, causing the spring 14 to be compressed. The stop block 4 will reduce the phenomenon of the zipper tooth body 11 sliding out of the zipper tape 1. During this process, the positioning rod 2 will be inserted into the groove 41, reducing the phenomenon of the zipper tooth body 11 not being able to slide to the end of the zipper tape 1.
[0030] Furthermore, such as Figure 3 As shown, a first magnetic block 5 is fixedly connected to the middle of the groove 41; a second magnetic block 51 is fixedly connected to the middle of the positioning rod 2; the first magnetic block 5 and the second magnetic block 51 correspond to each other; during operation, the positioning rod 2 is inserted into the groove 41, and the first magnetic block 5 and the second magnetic block 51 attract each other, so that when the zipper tooth body 11 is pulled up and the zipper tape 1 is closed, the position of the zipper tooth body 11 remains unchanged.
[0031] Furthermore, such as Figure 4 As shown, one end of the positioning rod 2 is fixedly connected to an anti-collision block 6; the anti-collision block 6 is correspondingly arranged with the zipper tooth body 11; during operation, the spring 14 is compressed, the sleeve rod 15 slides in the sleeve 13, one side of the unfolding plate 16 is close to the stop block 4, and the other side is close to the zipper tooth body 11. The anti-collision block 6 protects the positioning rod 2, reducing the occurrence of damage to the positioning rod 2 due to the collision between the zipper tooth body 11 and the positioning rod 2.
[0032] Working principle: First, pull the zipper tooth body 11. The zipper tooth body 11 slides on the zipper tape 1. During this process, the spreading plate 16 will extend the lining fabric near the zipper tooth body 11, reducing the phenomenon of wrinkles in the lining fabric when the zipper tooth body 11 approaches, which would cause the zipper tooth body 11 to clamp the lining fabric and cause the zipper tooth body 11 to get stuck. When the zipper tooth body 11 moves to the end of the zipper tape 1, the spreading plate 16 will be obstructed at the end and move backward. The sleeve 15 slides in the sleeve 13, and the spring 14 is compressed. This will not affect the tight connection between the zipper tooth body 11 and the zipper tape 1. By setting the spreading plate 16 to extend the zipper tooth body 11... During operation, the surrounding lining fabric is flattened to reduce jamming of the zipper teeth 11, allowing the zipper teeth 11 to run smoothly on the zipper tape 1. The positioning rod 2 is located at the front end of the zipper teeth 11, in the middle of the unclosed zipper tape 1. During operation, the positioning rod 2 also moves through the middle of the zipper tape 1, and the wax block 21 contacts the zipper tape 1 on both sides to apply wax. This further facilitates the smooth sliding of the zipper teeth 11 and reduces friction between the zipper teeth 11 and the zipper tape 1 that could cause jamming. By setting the positioning rod 2 and the wax block 21, the zipper tape 1 is waxed while it is running, increasing the friction between the zipper tape 1 and the zipper teeth 11. The lubrication level reduces the occurrence of jamming between the zipper tape 1 and the zipper tooth body 11. The spreading plate 16 moves with the zipper tooth body 11. When the spreading plate 16 moves at the bottom of the zipper tape 1, the sponge strip 3 will contact the bottom of the zipper tape 1 and wipe its surface. The bottom of the zipper tape 1 is on the inside, which will obstruct the view and make it difficult to observe the debris attached to its surface. The sponge strip 3 cleans it to reduce the contamination of debris, which will prevent jamming when the zipper tape 1 and the zipper tooth body 11 are engaged. When the spreading plate 16 is at the end of the zipper tape 1, it is obstructed by the stop block 4 and pushed and pulled by the zipper tooth body 11, causing the spring 14 to be compressed. The stop block 4 will reduce the jamming of the zipper tooth body. When the zipper body 11 slides out of the zipper tape 1, the positioning rod 2 will be engaged in the groove 41 during this process, reducing the phenomenon that the zipper tooth body 11 cannot slide to the end of the zipper tape 1. When the positioning rod 2 is engaged in the groove 41, the first magnetic block 5 and the second magnetic block 51 are close to each other and attract each other, so that when the zipper tooth body 11 is pulled up and the zipper tape 1 is closed, the position of the zipper tooth body 11 remains unchanged, the spring 14 is compressed, the sleeve rod 15 slides in the sleeve 13, the unfolding plate 16 is close to the stop block 4 on one side and close to the zipper tooth body 11 on the other side, and the anti-collision block 6 protects the positioning rod 2, reducing the phenomenon that the positioning rod 2 is damaged due to the collision between the zipper tooth body 11 and the positioning rod 2.
