When the mask 2 is adjusted to the preset full protection state, the mask closing angle limit limit point 28 is blocked by the mask opening and closing limiter 26 on the inner component 11 of the mask bracket quick-release connection component to realize the limiting function, preventing the mask 2 from sinking to an angle outside the pre-designed angle. The inner component 11 of the mask bracket quick-release connection component near one end of the rotating shaft component 9 is evenly provided with a mask specific angle limiter 25;

[0050] like Fig.12 and Fig.13As shown, three balls 10 are embedded in the rotating shaft assembly 9 according to a predetermined calculated spacing, and the spacing corresponds to the mask specific angle limiter 25.

When the steel column is moved into the steel column groove, the ball 10 will be subjected to a lateral force from the adjusting gasket 8 under the mediation of the adjusting gasket 8, so that the steel column is embedded in the steel column groove, generating resistance to the continued movement of the mask 2, thereby forming a function of limiting and fixing the mask 2 at a fixed angle when opening and closing.

[0051] The use process of a quick installation and disassembly system provided by the utility model is as follows: a mask bracket 3 with a quick-release connector mask bracket assembly 5 is installed, and the mask 2 is quickly installed by holding the ends of the two side masks 2 and directly inserting them into the quick-release connector helmet body assembly 6 on the helmet body 1. During insertion, since the wedge-shaped edge protrusion 19 is embedded in the wedge-shaped edge recessed groove 20 of the outer side screw 14 of the quick-release system helmet body part, the design of the wedge-shaped track that is narrow at the bottom and wide at the top makes it easy for the modules on both sides of the rear end of the mask bracket 3 to be inserted into the wedge-shaped grooves of the base of the quick-release system helmet body 1 on both sides of the mask 2. At the same time, the downward force will cause the slightly outwardly inclined square latch 18 on the paddle 12 to be squeezed toward the inside of the paddle 12 due to the constraint of the wedge-shaped groove, and the quick-release connector helmet body assembly 6 will slide smoothly into the wedge-shaped groove of the base of the quick-release system helmet body 1 through the deformation of the elastic rubber block 23 on the inner side of the paddle 12. After the quick-release connector helmet body assembly 6 smoothly slides into the wedge-shaped groove at the base of the quick-release system helmet body 1, the square latch 18 is aligned with the paddle latch groove 21 on the outer screw 14 of the quick-release system helmet body part, which has a completely matching shape. The resetting and rebounding effect of the elastic rubber block 23 allows the square latch 18 of the paddle 12 to enter the paddle latch groove 21, and the square latch 18 and the wedge-shaped latch groove are locked at the same time, firmly connecting the mask 2 and the helmet together.

[0052] One side of the paddle 12 is in contact with the elastic rubber block 23, and the paddle 12 can be moved by the elastic force of the elastic rubber block 23 itself, driving the square latch 18 on the paddle 12. In a normal state, the elastic rubber block 23 is not deformed and pushes the paddle 12 outward, so that the square latch 18 enters the paddle latch groove 21 on the outer screw 14 of the helmet body part of the quick release system. When the paddle 12 is moved toward the inner component 11 of the mask bracket quick release connecting component, the elastic rubber block 23 itself is squeezed, and its elastic force enables the paddle 12 to be moved, driving the square latch 18 on the paddle 12, so that the square latch 18 is separated from the paddle latch groove 21 on the outer screw 14 of the helmet body part of the quick release system, so that the mask 2 can be quickly lifted upward to achieve the function of quick installation or removal;

[0053] The direction operation room can easily and quickly separate and remove the mask 2 with the quick-release connector mask bracket assembly 5 from the quick-release connector helmet body assembly 6 by simultaneously pushing the paddles outward on both sides and sliding them upward on the head;

[0054] like Figure 3 As shown, the screw 14 on the outside of the helmet body of the quick release system is clearly located, which is very convenient for identifying the helmet body that has used the quick release system and for adapting the quick release mask 2 with the same quick release system. Figure 4 As shown, the mask bracket 3 with the quick-release connector mask bracket assembly 5 installed can be quickly installed by holding the ends of the two side masks 2 and directly inserting them into the quick-release connector helmet assembly 6 on the helmet body 1. By simultaneously pulling the paddles outward on both sides and sliding them upward above the head, the mask 2 with the quick-release connector mask bracket assembly 5 can be easily and quickly separated and removed from the quick-release connector helmet assembly 6, so that after the user wears the helmet with the quick-release connector helmet assembly 6 installed, if it is necessary to install the full-face, half-face and various protective masks 2 in time, it is only necessary to hold the two ends of the tail of the mask bracket 3 with the quick-release connector mask bracket assembly 5 installed with both hands, align with the card slots of the exposed parts on both sides of the helmet body 1 of the quick-release connector helmet assembly 6, and slide from top to bottom to complete the installation by hearing a click. When disassembling, the index fingers of both hands simultaneously pull the paddles 12 outward and push the mask bracket 3 as a whole toward the top of the head in parallel with the base of the palm, so that the mask 2 can be easily removed from the helmet body 1 to separate the mask 2 from the helmet body 1.
