[0031] 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 in 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.

[0032] The utility model provides Figure 1-4 The riot helmet mask locking device shown comprises a fixing head 1 and a bolt head 2 arranged outside the fixing head 1;

[0033] A fixing groove 11 is provided at the rear inner position of the fixing head 1;

[0034] An inner bolt 3 is arranged at the inner side of the bolt head 2;

[0035] A threaded barrel 8 is provided at the inner side of the bolt head 2, a fixing ring 7 is provided at the outer side of the threaded barrel 8, and internal threads 4 are provided at the connection positions between the outer side of the threaded barrel 8 and the inner wall of the inner bolt 3;

[0036] A fixing tube 5 is arranged at the middle position of the front side of the fixing head 1 , a connecting tube 10 is connected to the inner side of the fixing tube 5 , and a fixing rod 9 is connected to the end position of one side of the connecting tube 10 .

[0037] In this embodiment, the use principle is:

[0038] The riot helmet mask locking device is designed to provide a stable and reliable way to fix the helmet mask to prevent the mask from separating from the helmet during impact or intense movement. Its core principle is based on the following key components and mechanisms:

[0039] Threaded connection: Through the reverse design of the internal thread 4 and the locking thread 6, the connection between the threaded barrel 8 and the internal bolt 3 is more stable, preventing relative rotation when subjected to force and causing loosening.

[0040] Integrated connection: The connecting tube 10 and the fixing rod 9, the fixing tube 5 and the fixing head 1 are connected in an integrated manner, which enhances the stability and durability of the structure.

[0041] Hollow threaded barrel: The hollow design of the threaded barrel 8 allows the connecting barrel 10 to pass through it. Such a design ensures the compactness of the structure and facilitates operation.

[0042] Function of the fixing ring: The fixing ring 7 is integrally connected with the threaded tube 8, and the mask can be clamped and fixed by screwing the fixing ring.

[0043] Steps:

[0044] Install the fixing head: First, the operator needs to fix the fixing head 1 on the helmet through the fixing slot 11. This step ensures the initial connection between the entire locking device and the helmet.

[0045] Fix the mask: Next, align the fixing hole groove of the mask and press it down to the upper side of the inner bolt 3. At this time, the mask is temporarily placed on the inner bolt and is ready for the next step of fixing.

[0046] Tighten the fixing ring: Then, manually or with the aid of a tool, screw the fixing ring 7 into the inner bolt 3 using the threaded barrel 8. As the fixing ring is tightened, the mask is clamped between the inner bolt and the bolt head 2, achieving preliminary fixation.

[0047] Insert and rotate the connecting tube: Next, the connecting tube 10 is passed through the hollow parts of the fixing ring and the threaded tube 8 and inserted into the fixing tube 5. Subsequently, the connecting tube 10 is rotated so that it is tightly connected to the fixing tube 5 through the locking thread 6. This step further enhances the fixing effect of the mask.

[0048] Final locking: Since the directions of the internal thread 4 and the locking thread 6 are opposite, this design can effectively prevent the thread from loosening when the helmet is subjected to impact force, thereby ensuring a firm connection between the mask and the helmet.

[0049] Through the above steps, the riot helmet mask locking device can effectively fix the mask and improve the overall protective performance of the helmet.

[0050] like Figure 1-4 As shown, the connecting tube 10 and the fixing rod 9 are connected by an integrated connection method, a locking thread 6 is provided at the connection position of the connecting tube 10 and the fixing tube 5, the threaded tube 8 and the inner side of the inner bolt 3 are connected by an internal thread 4, the internal thread 4 and the locking thread 6 are in opposite directions, the threaded tube 8 is connected to the fixing ring 7 by an integrated method, the middle of the threaded tube 8 is hollow, the connecting tube 10 passes through the middle of the threaded tube 8, the fixing tube 5 is connected to the fixing head 1 by an integrated connection method, the threaded tube 8 can move in the inner bolt 3 by rotating on the internal thread 4, and the connecting tube 10 can move in the fixing tube 5 by rotating on the locking thread 6.

[0051] Preferably, the operator can fix the fixing head 1 on the helmet through the fixing groove 11, press the mask fixing hole groove down to the upper side of the inner bolt 3, and fix the fixing ring 7 by screwing it into the inner bolt 3 through the internal thread 4 using the threaded tube 8, and clamp and fix the mask using the fixing ring 7, the internal bolt 3 and the bolt head 2. Then, the connecting tube 10 can be passed through the fixing ring 7 and the threaded tube 8, inserted into the tight fixing tube 5 and rotated, and the threaded tube 8 and the fixing tube 5 can be connected through the locking thread 6 to ensure that the fixing rod 9 is firmly pressed down onto the fixing ring 7 and presses the fixing ring 7. The opposite thread directions of the internal thread 4 and the locking thread 6 can prevent the thread from loosening and prevent the mask and the helmet from separating when the helmet is subjected to impact force.

[0052] 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.
