[0024] The utility model will be further explained in detail below with reference to the drawings.

[0025] As Figures 1-12 shown, a police riot helmet, comprising a helmet shell 01, a mask 02 provided at the front of the helmet shell 01, a neck protector 03 provided at the back of the helmet shell 01, and six belts 04 and a cap top pad 05 provided in the top of the helmet shell 01 in sequence and connected with the inside of the helmet shell 01. The six belts 04 and the cap top pad 05 form a gap therebetween. The six belts 04 and the helmet shell 01 form a gap therebetween. The six belts 04 are arranged at equal intervals in the top of the helmet shell 01, and are connected to the helmet by screws or buckles.

[0026] Ventilation devices 06 are provided between the helmet shell 01 and the cap top pad 05 at the positions corresponding to the gaps. The ventilation devices 06 are respectively provided between the helmet shell 01 and the cap top pad 05 on both sides of the top of the helmet shell 01. The ventilation device 06 comprises a first air guide hole 61 provided on the top of the cap top pad 05 and penetrating the inside and outside, a second air guide hole 62 provided on the helmet shell 01 at the position corresponding to the first air guide hole 61 and communicating with the first air guide hole 61, and a switch structure 63 provided on the inner wall of the helmet shell 01 at the position corresponding to the second air guide hole 62 and opening or closing the second air guide hole 62. The second air guide hole 62 communicates the inside and outside of the helmet shell 01. The first air guide hole 61 communicates with the second air guide hole 62.

[0027] The switch structure 63 comprises a fixed plate 631 installed on the helmet shell 01 at the position corresponding to the second air guide hole 62, an inner recess 632 provided on the inner surface of the fixed plate 631, a third air guide hole 633 provided on the fixed plate 631 at the inner recess 632 and communicating with the first air guide hole 61 and the second air guide hole 62 respectively, a baffle 634 provided in the inner recess 632 and sliding up and down by external force to open or close the second air guide hole 62, a first clamping groove 635 provided on the baffle 634 and guiding the baffle 634 to slide up and down, a first clamping strip 636 provided on the fixed plate 631 at the position corresponding to the first clamping groove 635 and clamped in the first clamping groove 635, a second clamping groove 637 provided on the fixed plate 631 and cooperating with the baffle 634 to guide the baffle 634 to slide up and down, a second clamping strip 638 provided on the baffle 634 at the position corresponding to the second clamping groove 637 and clamped in the second clamping groove 637, and a handle 639 provided on the baffle 634 and extending outwardly through the second air guide hole 62 from the inside.

[0028] When the switch structure 63 is used, the handle 639 is pushed up from the outside of the helmet shell 01, the baffle 634 moves upward along with the external force, and the first clamping strip 636 on the fixed plate 631 and the second clamping strip 638 on the baffle 634 move upward along the directions of the first clamping groove 635 and the second clamping groove 637 respectively, until the baffle 634 blocks the second air guide hole 62, thereby closing the second air guide hole 62.

[0029] To open the second air hole 62, just push the handle 639 downward from the outside of the helmet shell 01, the baffle 634 will move upward with the external force until the second air hole 62 and the third air hole 633 are communicated.

[0030] The top pad 05 corresponds to the shape of the top of the helmet shell 01. The top surface of the top pad 05 is provided with an annular ventilation groove 51 communicated with the first air hole 61. The annular ventilation groove 51 is communicated with the first air hole 61, the second air hole and the third air hole 633. The above-mentioned annular ventilation groove 51 is an inner recess ring on the top surface of the top pad 05, which has the same center and is provided with a plurality of rings expanding from inside to outside, and part of the inner recess ring is communicated with the first air hole 61.

[0031] The face shield 02 is provided with a position adjusting device 07 between the both sides and the helmet shell 01.

[0032] The position adjusting device 07 comprises a mounting seat 71 provided on the side of the helmet shell 01, an arc-shaped rack 72 provided on the mounting seat 71, a first limiting hook 73 and a second limiting hook 74 provided on the upper and lower ends of the arc-shaped rack 72 respectively, a connecting arm 75 provided on the mounting seat 71 on the side of the first limiting hook 73, one end of which is bolted with the mounting seat 71 and the other end of which is connected with the face shield 02, a roller 76 provided on the connecting arm 75 between the connecting arm 75 and the mounting seat 71, which rolls along the arc-shaped rack 72, and a guide clamping block 77 provided on the connecting arm 75, which clamps the second limiting hook 74. The arc-shaped rack 72 is an arc-shaped rack 72 with an angle of 45 degrees. The connecting arm 75 rotates with the upper end of the arc-shaped rack 72 as the connecting base point, and the face shield 02 is turned up at the same time, and the roller 76 on the connecting arm 75 rolls in the range of the arc-shaped rack 72.

[0033] The working principle of the face shield 02 adjusted by the position adjusting device 07 is as follows: when the face shield 02 is turned up, the connecting arms 75 on both sides rotate with the upper end of the arc-shaped rack 72 as the connecting base point, and the roller 76 on the connecting arm 75 rolls in the range of the arc-shaped rack 72, and after the connecting arm 75 rotates by an angle of 45 degrees, the face shield 02 is in an open and flat state, thereby realizing the function of opening the face shield 02. In addition, since the roller 76 is a roller 76 with a surface having elasticity, when it is necessary to turn up or turn down to adjust the face shield 02 to different angles, the connecting arm 75 driven by the external force can stop at any position of the tooth trace of the arc-shaped rack 72 during the process, thereby achieving the purpose of different angles of the face shield 02.

[0034] The working principle of the police anti-riot helmet is that: the six belts 04 and the helmet shell 01 form a gap, and the six belts 04 and the top pad 05 form a gap, and the gap is provided with a ventilation device 06 which is communicated with the outside. The purpose of this design is to ensure that the heat generated during the use of the police anti-riot helmet is gathered to the gap position, and then the hot air in the helmet is discharged to the outside through the ventilation device 06, so that the ventilation and air permeability comfort during use can be improved; and the opening or closing of the ventilation device 06 can be adjusted by the user according to the comfort condition of the user through the baffle 634.

[0035] In addition, in order to further improve the ventilation and air permeability comfort, the face mask 02 can be opened upward, so that the first air guide hole 61, the second air guide hole 62 and the third air guide hole 633 in the ventilation device 06 form a convection effect.

[0036] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, a number of modifications and improvements can be made, which are all within the scope of protection of the application.
