[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For reference Figure 1-7 The utility model is described as follows:

[0024] Embodiment 1: A zipper tape 1 with an anti-loosening structure comprises a zipper tape 1, and a zipper head 2 is connected to the zipper tape 1. The above is the prior art, and the following is the improved technical solution of this application:

[0025] The anti-loosening block 3 is also included. The anti-loosening block 3 is a rectangular block structure and is made of plastic. The anti-loosening block 3 is fixedly arranged at one end of the zipper tape 1. The anti-loosening block 3 is provided with a connecting groove 4 facing the zipper head 2, and the two side walls of the connecting groove 4 are provided with protruding holding parts 5.

[0026] The width of the zipper head 2 gradually increases from the middle to the two ends, and holding grooves 6 are formed on both sides of the middle of the zipper head 2. The zipper head 2 enters the connecting groove 4 (the opening side of the connecting groove 4 is provided with a chamfer 7, and the chamfer 7 guides the zipper head 2 to enter the connecting groove 4), (a deformation opening slit 8 is provided at the bottom of the connecting groove 4, and the deformation opening slit 8 is arranged along the opening direction of the connecting groove 4. The deformation opening slit 8 is connected to the connecting groove 4, and the deformation opening slit 8 runs through both sides of the thickness direction of the anti-loosening block 3. With this technical solution, when the zipper head 2 enters the connecting groove 4, the anti-loosening block 3 can be forced to open and deform, which facilitates the zipper head 2 to enter the connecting groove 4), the holding part 5 is connected to the holding groove 6, and the holding part 5 cooperates with the holding groove 6 to limit the zipper head 2 from escaping from the connecting groove 4 along the opening direction of the connecting groove 4.

[0027] A limiting portion 9 is provided on one side of the anti-loosening block 3 away from the zipper tape 1 in the thickness direction. The limiting portion 9 is arranged on both sides of the connecting groove 4. The limiting portion 9 can prevent the zipper head 2 from escaping from the connecting groove 4 in the thickness direction of the anti-loosening block 3.

[0028] The zipper slider 2 is restricted in the connecting groove 4 by adopting the above technical solution.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
