Abstract:
Disclosed are zipper teeth (2, 20), a zipper chain, and a zipper (100). Zipper teeth (2, 20) and a tape (10) are arranged together to form the zipper chain. Each zipper tooth (2, 20) comprises a body part (21, 201), a mounting part (22, 202), a neck part (23, 203), and a head part (24, 204). The neck part (23, 203) connects the body part (21, 201) with the head part (24, 204); the mounting part (22, 202) is used for arrangement of the tape (10). The body part (21, 201) comprises an upper body part (211, 2011) and a lower body part (212, 2012), wherein at least one of the upper body part (211, 2011) and the lower body part (212, 2012) comprises a raised part (25) and a base part (28), the raised part (25) projecting from the base part (28) and being located in the middle position in a front-rear direction and extending in a left-right direction. Further, an inclined part (26) inclining downwards in the left-right direction is formed on at least one side in a vertical direction of the head part (24, 204), and protrusions (27) extending in the front-rear direction are provided on two sides of the raised part (25). The zipper teeth (2, 20), the zipper chain, and the zipper (100) can be realized light weight, and ensure the strength and reliability in use.
