DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 A bulletproof helmet comprises an outer helmet body 1 and an inner helmet body 2, and a bulletproof glass fiber reinforced plastic layer 3 arranged between the outer helmet body 1 and the inner helmet body 2; a mounting member 4 arranged at the bottom of the inner helmet body 2 for connecting the outer helmet body 1 and the inner helmet body 2; a side plate body 5 fixedly mounted on both sides of the bottom of the inner helmet body 2; a goggles 7 is installed between the two side plates 5 through an elastic member 6, the mounting member 4 comprises four support rods 41 fixedly mounted on the top of the inner helmet body 2, the tops of the four support rods 41 all penetrate the top of the outer helmet body 1 and are threadedly mounted with nuts 42, the surfaces of the support rods 41 are movably sleeved with support springs 43, the tops of the support springs 43 are clamped with fitting rings 44, a plurality of support bars 8 are fixedly mounted on the top of the inner helmet body 2, the fitting rings 44 and the inner parts of the support springs 43 are movably sleeved with the surfaces of the support rods 41.

[0023] In this embodiment, the bottom hole of the outer helmet body 1 is inserted into the four support rods 41, and the nuts 42 are threadedly installed on the top of the support rods 41, so as to complete the connection between the outer helmet body 1 and the inner helmet body 2, wherein a bulletproof glass fiber reinforced plastic layer is reserved between the outer helmet body 1 and the inner helmet body 2, and the bulletproof glass fiber reinforced plastic layer 3 can be removed to reduce the weight of the helmet, so that the helmet can be used in different environments. At the same time, when the outer helmet body 1 is hit, the outer helmet body 1 will slide on the support rods 41 and squeeze the support springs 43, which has a certain buffering effect on the impact. At the same time, the support strip 8 is a rubber strip to better protect the wearer's head. A D-buckle lock is set at the bottom of the helmet, which is convenient for the wearer to use and is more firmly installed.

[0024] Furthermore, the elastic member 6 includes a support column 61, a return spring 62, a movable gear disc 63 and a rotating gear disc 64. The support column 61 is fixedly installed on the opposite side of the two side plates 5. The movable gear disc 63 is movably sleeved on the surface of the support column 61. The support spring 43 is clamped between the movable gear disc 63 and the side plate body 5. The rotating gear disc 64 is fixedly installed on both sides of the inner wall of the goggles 7. The rotating gear disc 64 is meshed with the movable gear disc. One end of the support column 61 passes through the movable gear disc and one side of the goggles 7 and extends.

[0025] The above design rotates the goggles 7 on the two support columns 61, and the rotating toothed disc 64 on the inner wall of the goggles 7 continuously pushes the moving toothed disc 63 to slide on the support columns 61. Under the action of the support spring 43, the moving toothed disc 63 always fits the rotating toothed disc 64, thereby enhancing the damping force on the rotation of the goggles 7 and preventing the goggles 7 from shaking.

[0026] Furthermore, two slide bars 9 are fixedly mounted on one side of the moving toothed disc 63, and a slide groove 10 for sliding the two slide bars 9 is provided on one side of the side plate 5. In the above design, the two slide bars 9 on one side of the moving toothed disc 63 are matched with the two slide grooves 10 on one side of the side plate 5, so that the moving toothed disc 63 is prevented from rotating and the moving toothed disc 63 is restricted to move only.

[0027] Furthermore, it also includes a limiter 11 for fixing an external device, and the limiter 11 includes a fixing frame 111, a compression spring 112, a short rod 113 and a clamping seat 114. The fixing frame 111 is fixedly installed on one side of the outer helmet body 1, and two short rods 113 are slidably installed on one side of the fixing frame 111. The clamping seat 114 is fixedly installed on one end of the two short rods 113, and two compression springs 112 are clamped between one side of the clamping seat 114 and the fixing frame 111. The above design, by placing an external device, such as a sports camera, on the fixing frame 111, and pushing the clamping seat 114 to fix the sports camera through the compression spring 112, has a preliminary clamping effect on the external device, which is convenient for connection with external accessories.

[0028] Furthermore, the top of the clamping seat 114 is threadedly installed with an adjusting rod 12, and the bottom of the adjusting rod 12 is fixedly installed with a pressing plate 13. The above design drives the pressing plate to move downward by rotating the adjusting rod 12, and vertically squeezes and fixes the external device, thereby enhancing the fixing effect of the external device.

[0029] Furthermore, a plurality of wire harness buckles 14 are fixedly mounted on the top of the outer helmet body 1. In the above design, the wire harness buckles 14 are arranged to arrange the connecting wires to avoid the entanglement of the cables and affect the use of the helmet.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
