The soft glue 8 is slidably connected to the inside of the sliding groove. The soft glue 8 can be squeezed inside the sliding groove, so that the prism 13 can be fixed inside the sliding groove. Two rubber blocks are fixedly connected to the top of the mounting top plate 5. A groove is provided inside the bottom mounting plate 3. The rubber block is arranged inside the groove. The rubber block and the groove cooperate to achieve rapid installation. When installing the arc-shaped plastic insert 2, first insert the arc-shaped plastic insert 2 into the gap of the helmet 1. Since the arc-shaped plastic insert 2 and the helmet are fixed together, the arc-shaped plastic insert 2 is inserted into the gap of the helmet 1. 1. There is a curvature difference in the arc. The arc-shaped plastic insert 2 is fixed to the helmet 1 by the tension of the extrusion deformation. At the same time, the magnetic force of the magnet 4 can be used to attract the mounting top plate 5 to the bottom of the bottom mounting plate 3, and can be slidably connected to the inside of the slide groove 6 through the slide column 7. The position of the adjustment mechanism 12 and the mounting block 11 can be adjusted, so that the position of the prism 13 can be adjusted through the connecting rod 10. The extrusion force of the soft glue 8 can be used to squeeze the soft glue 8 into the inside of the slide groove, so that the slide column 7 can be fixed to the inside of the bottom mounting plate 3, and then the prism 13 can be pre-fixed.
[0019] The adjusting mechanism 12 includes a rotating rod 1201, which can rotate on the outside of the rotating shaft 9, and the bottom of the rotating rod 1201 is fixedly connected to the top of the mounting block 11. The outside of the rotating shaft 9 is rotatably connected to the inside of the rotating rod 1201. The outside of the rotating rod 1201 is fixedly connected with a plurality of limit bars 1202, and the outer bottom end of the limit bar 1202 is fixedly connected with a fixed disk 1203. The fixed disk 1203 can play a role in limiting. The outside of the rotating rod 1201 is slidably connected with a lower gear ring 1205, and the outer sleeve of the rotating rod 1201 is provided with a reset spring 1204. The reset spring 1204 can push the lower gear ring 1205 to reset in the absence of external force. The outer sleeve of the rotating rod 1201 is provided with an upper gear ring 1206, and the lower gear ring 1206 is provided. The engagement of the gear ring 1205 with the upper gear ring 1206 can prevent the prism 13 from rotating. Two engaging posts 1207 are provided on the top of the upper gear ring 1206, and a plurality of limiting holes 1208 are provided at the bottom of the mounting top plate 5. After the engaging posts 1207 are inserted into the limiting holes 1208, the sliding of the sliding post 7 can be limited. One end of the return spring 1204 is fixedly connected to the bottom of the lower gear ring 1205, and the other end of the return spring 1204 is fixedly connected to the top of the fixed plate 1203. The upper gear ring 1206 is arranged on the outside of the rotating rod 1201, and the outside of the engaging posts 1207 is engaged with the inside of the limiting holes 1208. The upper gear ring 1206 and the lower gear ring 1205 are meshed. The prism 13 is prevented from rotating by the engaging column 1207 on the upper gear ring 1206. The sliding inner portion of the lower gear ring 1205 is connected to the outside of the plurality of limiting bars 1202. The bottom of the fixed plate 1203 is fixedly connected to the top of the mounting block 11. The arc-shaped plastic insert 2 is elastic, so that the lower gear ring 1205 can be driven to move upward under the action of the return spring 1204, thereby driving the upper gear ring 1206 to move upward and making the engaging column 1207 on the upper gear ring 1206 engage with the inner portion of the limiting hole 1208. At this time, the rotating rod 1201 cannot move under the limit of the upper gear ring 1206, and the engagement of the upper gear ring 1206 and the lower gear ring 1205 makes the rotating rod 1201 The movable rod 1201 will not rotate, so that the mounting block 11, the connecting rod 10 and the prism 13 will not rotate. When the rotating rod 1201 needs to be rotated, the lower gear ring 1205 is first rotated downward and the distance between the lower gear ring 1205 and the upper gear ring 1206 is pulled away. At this time, the rotating rod 1201 can be rotated, and then the mounting block 11, the connecting rod 10 and the prism 13 can be rotated. After the angle is adjusted, the lower gear ring 1205 is released again, and the lower gear ring 1205 can be driven to move upward under the action of the reset spring 1204, and the lower gear ring 1205 can be engaged with the upper gear ring 1206. Since the upper gear ring 1206 is limited to the lower limit at the engaging column 1207 and the limiting hole 1208,Thus, the upper gear ring 1206 and the lower gear ring 1205 can be limited, thereby limiting the rotation of the mounting block 11 and enabling the angle to be adjusted.
[0020] Working principle: When installing the curved plastic insert 2, first insert the curved plastic insert 2 into the gap of the helmet 1. Due to the curvature difference between the curved plastic insert 2 and the helmet 1, the curved plastic insert 2 is fixed to the helmet 1 through the tension of the extrusion deformation. At the same time, the magnetic force of the magnet 4 can be used to suck the mounting top plate 5 to the bottom of the bottom mounting plate 3, and the sliding column 7 can be slidably connected to the inside of the slide groove 6 to adjust the position of the adjustment mechanism 12 and the mounting block 11, so that the position of the prism 13 can be adjusted through the connecting rod 10, and the extrusion force of the soft glue 8 can be used to squeeze the soft glue 8 into the inside of the slide groove, so that the sliding column 7 can be fixed to the inside of the bottom mounting plate 3, and then the prism 13 can be pre-fixed. When the sliding post 7 needs to be slidably connected to the inside of the sliding groove 6, the upper gear ring 1206 is first pressed downward, and then the lower gear ring 1205 can be driven to move downward, thereby compressing the return spring 1204 and allowing the engaging post 1207 on the upper gear ring 1206 to move out of the inner limit hole 1208, thereby enabling the sliding post 7 to slide. When the sliding post 7 reaches the position, the upper gear ring 1206 is released, so that the lower gear ring 1205 can be driven to move upward under the action of the return spring 1204, thereby driving the upper gear ring 1206 to move upward and allowing the engaging post 1207 on the upper gear ring 1206 to engage with the inner limit hole 1208. At this time, the rotating rod 1201 cannot move under the limitation of the upper gear ring 1206, and the rotating rod 1201 will not rotate due to the engagement of the upper gear ring 1206 and the lower gear ring 1205. When the rotating rod 1201 needs to be rotated, the lower gear ring 1205 is first rotated downward and the distance between the lower gear ring 1205 and the upper gear ring 1206 is pulled away. At this time, the rotating rod 1201 can be rotated, and then the mounting block 11, the connecting rod 10 and the prism 13 can be driven to rotate. After the angle is adjusted, the lower gear ring 1205 is released again, and the lower gear ring 1205 can be driven to move upward under the action of the return spring 1204, and the lower gear ring 1205 can be engaged with the upper gear ring 1206. Since the upper gear ring 1206 cooperates with the lower limit of the engaging column 1207 and the limiting hole 1208, the upper gear ring 1206 and the lower gear ring 1205 can be limited, thereby limiting the rotation of the mounting block 11, and then facilitating the adjustment of the angle.
