In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a portable folding helmet, includes the bent anter that changes, the lower extreme that the bent anter that changes is provided with articulated ear, and the middle hinge hole of articulated ear is provided with articulated spacer pin, and the side of the hinge hole of articulated ear is provided with articulated spacing hole, is provided with return spring in the middle of the inside of articulated spacer pin, and the surface of articulated spacer pin is close to the inboard one end of bent anter and is provided with bent piece of turning, and the opposite side of bent piece of turning is provided with bent back part, and bent back part lean on inside one side and be provided with articulated handhole door.

Preferably, the inside of the front piece, the middle piece and the back piece is provided with a limiting groove.

Preferably, torsion springs are arranged between the front bending piece and the middle bending piece and between the middle bending piece and the rear bending piece.

Preferably, the limiting step on the surface of the hinge limiting pin is of a structure with a small outside and a large inside.

Preferably, the hinged hole cover is buckled with the groove of the bent back piece ear part through a bayonet at the side edge.

Preferably, the rotation angle of the middle bending piece relative to the front bending piece matched with the middle bending piece is sixty degrees, and the rotation angle of the rear bending piece relative to the middle bending piece matched with the rear bending piece is sixty degrees.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses with the horizontal modularization of a complete helmet, a complete folding helmet is by there being three inside and outside cooperation, the bent piece that the piece was buckled constitutes, be defined as bent exhibition anter with three bent exhibition piece respectively, piece in the bent exhibition, bent exhibition back part, every bent exhibition piece is through articulated linking to each other, all can round the pin joint rotation, the effectual volume that has reduced when not wearing the helmet, for the rider provides very big facility, can improve the helmet rate of wear effectively, thereby the mortality that causes owing to not wearing the helmet has been reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a portable folding helmet, including bent anter 6 that changes, the lower extreme that bent anter 6 changes is provided with articulated ear 8, the middle hinge hole of articulated ear 8 is provided with articulated spacer pin 1, the side of the 8 hinge hole of articulated ear is provided with articulated spacing hole 2, be provided with return spring 9 in the middle of the inside of articulated spacer pin 1, the surface of articulated spacer pin 1 is close to bent 6 inboard one ends in anter and is provided with bent piece 5 of turning, the opposite side of bent piece 5 of turning is provided with bent back part 4, bent back part 4 lean on inside one side and be provided with articulated handhole door 3.

In particular, the inner parts of the front bending piece 6, the middle bending piece 5 and the rear bending piece 4 are all provided with a limiting groove 7,

through adopting above-mentioned technical scheme, spacing step and spacing groove 7 cooperation play spacing effect.

Specifically, torsion springs 10 are arranged between the front bending piece 6 and the middle bending piece 5 and between the middle bending piece 5 and the rear bending piece 4,

by adopting the technical scheme, the helmet piece always keeps the unfolding trend under the action of the torsion spring 10.
