A connecting plate 8 is fixedly connected to the front side of the two springs 7, a pressing block 9 is fixedly connected to the top of the front side of the connecting plate 8, and a fitting block 10 is fixedly connected to the bottom of the front side of the connecting plate 8. A connecting groove 17 is provided at the bottom of the connector 5, and the fitting block 10 is slidably connected to the middle of the connecting groove 17. The connecting groove 17 is communicated with the groove 6, and the top of the pull ring 4 is slidably connected in the connecting groove 17. A slot 11 is provided at the top of the pull ring 4, and the fitting block 10 is fitted and connected in the slot 11.

[0034] Specifically, the zipper fabric 1 is composed of two separate pieces of fabric, which are connected by the zipper teeth 2 of the zipper, and are the main body of the entire zipper system. The zipper teeth 2 are located on the opposite sides of the two zipper fabrics 1, and these teeth can mesh with each other to form the main closing mechanism of the zipper. The pull head 3 is located at the front end of the zipper teeth 2 on both sides, and is used to open or close the zipper. The movement of the pull head 3 causes the opening and closing of the zipper. The pull ring 4 is located at the front end of the pull head 3, through which the pull head 3 can be locked to improve the safety of the zipper. The connector 5 is located at the top of the two zipper fabrics 1, and is used to lock the pull ring 4. The spring 7 is fixed inside the connector 5 to provide elastic support for the connecting plate 8. The groove 6 is located inside the connecting piece 5 and is used to fix the spring 7 to ensure the position and function of the spring 7. The connecting plate 8 is connected to the front end of the spring 7 and is connected to other components through the pressing block 9 and the engaging block 10 to play a supporting and fixing role. The pressing block 9 is used to squeeze the connecting plate 8 to press down the spring 7. The engaging block 10 is used to fix it through the slot 11 at the top of the pull ring 4. The connecting groove 17 is located at the bottom of the connecting piece 5, and the pull ring 4 slides therein to fix the pull head 3. The connecting groove 17 is connected to the groove 6 to provide an interactive channel between the connecting plate 8 and the engaging block 10, ensuring that they can cooperate with each other during use.

[0035] Reference Figure 4-5 The meshing assembly 15 includes a plurality of teeth 151, and the plurality of teeth 151 are respectively fixedly connected to the separated sides of the two zipper cloths 1, and the separated sides of the two zipper cloths 1 are slidably connected with the connecting member 2 12, and the two connecting members 2 12 are provided with tooth grooves 152 on the opposite sides, and the teeth 151 on the left and right sides are respectively slidably connected in the two tooth grooves 152.

[0036] Specifically, the teeth 151 are used to be slidably connected in the tooth groove 152, so that the two zipper cloths 1 are separated from each other and the teeth 151 are driven to slide in the tooth groove 152, so that the entire anti-theft zipper is installed, and the second connector 12 is an installation member.

[0037] Reference Figure 4-5 The fixing assembly 16 includes a plurality of springs 161, which are respectively fixedly connected to the separated sides of the two zipper cloths 1. The separated sides of the two zipper cloths 1 are provided with a limiting groove 14. The left and right springs 161 are respectively fixedly connected to the left and right limiting grooves 14 on the opposite sides. The left and right springs 161 are respectively fixedly connected to the separated sides with a clamping block 162. The two connectors 12 are respectively provided with a clamping groove 13 on the opposite sides. The separated sides of the left and right clamping blocks 162 are respectively embedded in the left and right clamping grooves 13 on the opposite sides.

[0038] Specifically, the second spring 161 is used to provide a certain tension and elasticity for the block 162, and the limiting groove 14 is used to limit the movement range of the second spring 161, which helps to ensure that the second spring 161 applies force at the appropriate position while avoiding excessive extension or compression. The block 162 is fixedly connected to one side of the second spring 161 and is used to connect to the second connector 12. The second slot 13 is located on the second connector 12 and is used to fix the block 162, thereby connecting and fixing the zipper cloth 1 to the second connector 12.

[0039] Working principle: When the pull ring 4 is pulled, it drives the slider 3 to move upward. The slider 3 squeezes the zipper teeth 2 on both sides to make them mesh with each other, thereby closing the zipper. Pressing the pressing block 9 will compress the spring 7, and the connecting plate 8 will also be driven, causing the engaging block 10 to contract, and then the top of the pull ring 4 will be slid and connected to the connecting groove 17. When the pressing block 9 is released, the spring 7 will release the tension, pushing the connecting plate 8 and the engaging block 10 to rebound, and the engaging block 10 will be embedded in the card at the top of the pull ring 4. The slider 3 is firmly fixed in the slot 11 to prevent it from being accidentally pulled open, thereby increasing safety. Pressing the block 162 will squeeze the spring 2 161 to press it into the limiting slot 14, and the teeth 151 on the separated side of the zipper cloth 1 will slide in the tooth grooves 152 on the opposite side of the connecting pieces 2 12 on both sides. The block 162 is aligned with the slot 2 13, and then the spring 2 161 releases the tension, pushing the block 162 to fit into the slot 2 13, and the zipper cloth 1 is connected and fixed to the connecting piece 2 12.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
