The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model embodiment provides a ring zipper with a locking structure, comprising: a fabric tape 1, with chain teeth 2 fixedly connected to both ends of the inner side of the fabric tape 1, the chain teeth 2 being distributed in a crisscross pattern, a slidably connected pull head 3 to the upper end of the chain teeth 2, an upper plate 15 at the upper end of the pull head 3, a hole at the front end of the upper plate 15, a thread inside the hole at the front end of the upper plate 15, a square slot at the upper end of the upper plate 15, and a pull nose 9 slidably connected to the inner side of the square slot at the upper end of the upper plate 15;

[0024] The front end of the nose 9 has a screw hole 14. The size of the screw hole 14 at the front end of the nose 9 is the same as the size of the hole at the front end of the upper plate 15, and the thread size is also the same.

[0025] A handle 11 is slidably connected to the inside of the nose 9. A through hole is provided at the front end of the handle 11. The through hole at the front end of the handle 11 cooperates with the nose 9 to allow the handle 11 to slide on the upper end of the nose 9.

[0026] A support core 12 is fixedly connected to the lower center of the upper plate 15, and a lower plate 13 is fixedly connected to the lower end of the support core 12. The support core 12 can separate the chain teeth 2 that were originally interlocked one by one.

[0027] The upper plate 15 has a bolt 10 connected to the threaded hole 14 at the front end. The bolt 10 has a cross-shaped groove at the front end, which can be unscrewed or tightened with a Phillips screwdriver without the need for other tools, making the operation simple and convenient.

[0028] A pin 6 is fixedly connected to the right side of the fabric strip 1. The pin 6 has protrusions on both sides. The protrusions at the front end of the pin 6 and the grooves in the slot 8 cooperate with each other to achieve the purpose of locking.

[0029] A pin sleeve 4 is fixedly connected to the left side of the fabric belt 1. The rear end is a U-shaped iron 7. A slot 8 is opened at the front left side of the pin sleeve 4. The U-shaped iron 7 can make the pin sleeve 4 firmly fixed to the inside of the fabric belt 1.

[0030] The front end of the fabric belt 1 is fixedly connected with a stop head 5. The positions of the stop heads 5 are corresponding to each other. The stop head 5 is fixed to the upper end of the fabric belt 1. The stop head 5 can prevent the pull head 3 from sliding out of the top of the chain tooth 2 when the chain tooth 2 is pulled.

[0031] Working principle: In use, align the pin 6 with the inside of the slot 8 on the inside of the pin sleeve 4, align the protrusion of the pin 6 with the groove inside the slot 8, and insert the pin 6 downwards. The tight fit between the pin 6 and the slot 8 allows the pull head 3 above to be pulled. The pull head 3 consists of an upper plate 15, a support core 12, a lower plate 13, a pull nose 9, and a handle 11. Pulling the handle 11 causes the pull nose 9 to move the upper plate 15, support core 12, and lower plate 13 forward. Under the action of the pull head 3, the chain teeth 2 at both ends are engaged. The engagement of the chain teeth 2 can limit the fabric tape 1 at both ends so that it cannot move outwards. There are two pull heads 3 at the upper end of the chain teeth 2, which are opposite each other. The zipper pulls 3 work together to enable the zipper to open and close in both directions, making operation more flexible and providing safety redundancy. If one zipper pull 3 is damaged, the other zipper pull 3 can continue to work. The upper plate 15 at the top of the zipper pull 3 has a hole at the front end with a thread inside. The front end of the zipper nose 9 also has a screw hole 14, and the size of the holes and threads of both are equal. The upper plate 15 and the screw hole 14 are connected by a bolt 10, which can firmly fix the zipper nose 9 in the upper plate 15. When the zipper nose 9 or the handle 11 is damaged, the zipper nose 9 can be disassembled by simply loosening the bolt 10 with a Phillips screwdriver, thereby replacing the zipper nose 9 or the handle 11.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
