Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Figures 1 and 2, is a kind of crash helmet disclosed by the utility model, including cap shell 1, the side setting of cap shell 1
There is cap along 16, the edge in cap shell 1 along cap shell 1 is provided with cap hoop 11, on cap hoop 11 after the position far from cap edge is provided with
Neck hoop 12, posterior neck hoop 12 include the protection block 121 being fixedly connected with 11 one end of cap hoop, and the other end of cap hoop 11 is fixedly connected with
A fixed 122(is shown in Fig. 3)
Referring to Fig. 3 and Fig. 4, protection block 121 is shown in Fig. 5 in offering fixing groove 123(on the face far from cap hoop 11), fixed strip
122 may move into fixing groove 123, hingedly be provided with card adapter plate 124, card adapter plate in the position far from cap hoop 11 in protection block 121
Hinged position is provided with the first torsional spring 126 on 124, the length direction on fixed strip 122 along fixed strip 122 offers multiple
Clamping groove 125, card adapter plate 124 can be clamped after being rotated by hinge joint to clamping groove 125, in order to promote the comfort of human body,
Spongy layer (not shown) is provided on the face in cap shell 1 in protection block 121.
Referring to Fig. 2 and Fig. 6, the position close to posterior neck hoop 12 is provided with protection board 13 in cap shell 1, after protection board 13 is located at
The outside of neck hoop 12 offers sliding slot 131 in the position where protection board 13 in cap shell 1, sliding slot 131 along cap shell 1 arc side and
Perpendicular to the length direction setting of fixed strip 122, it is provided with the sliding block 132 being slidably connected in sliding slot 131 on protection board 13, is
It avoids the corner of protection board 13 from causing to damage to human body, the corner of protection board 13 is disposed as chamfering.
When putting on the helmet, by protection board 13 by sliding block 132 and sliding slot 131 towards moving above cap shell 1, so that posterior neck hoop 12
Be exposed, be detached from card adapter plate 124 in clamping groove 125, at this time fixed strip 122 can towards moving in fixing groove 123 or
It is mobile outside towards fixing groove 123, so that the size variation of entire cap hoop 11, after the size of adjusting cap hoop 11 is suitable, by hinged
Point rotates card adapter plate 124 towards fixed strip 122, and card adapter plate 124 will drive the rotation of the first torsional spring 126, be clamped card adapter plate 124 to right
In the clamping groove 125 answered, since the elasticity meeting card adapter plate 124 that the rotation of the first torsional spring 126 generates is rotated towards protection block 121, and block
In the clamping to clamping groove 125 of fishplate bar 124, therefore card adapter plate 124 can fix the position of fixed strip 122, finally slide protection board 13,
It blocks it by posterior neck hoop 12, by entering fixed strip 122 in protection block 121, and protection board is set on the outside of posterior neck hoop 12
13, external object can be prevented to collide posterior neck hoop 12 and cause the damage of posterior neck hoop 12.
Referring to Fig. 2 and Fig. 7, the two sides in cap shell 1 close to cap edge are hingedly provided with fixing belt 14, in hinged in fixing belt 14
Position be provided with the second torsional spring 15, fixing belt 14 includes the passive belt 141 being hingedly arranged with cap shell 1 and sliding plug in passive
With the main belt 142 in 141, it is provided with jumping bean spring 143 in main belt 142, along the length of passive belt 141 on passive belt 141
Degree direction offers multiple blocked holes 144, in order to make fixing belt 14 be bonded face's curve of people, by main belt 142 far from passive
Position with 141 is set as arc.
When the helmet is worn to head, fixing belt 14,14 meeting of fixing belt are rotated towards the position far from cap shell 1 by hinge joint
It drives the second torsional spring 15 to rotate, then loosens fixing belt 14, the second torsional spring 15 is since the elastic meeting of rotation generation is so that fixing belt
14 rotate towards cap shell 1, so that fixing belt 14 conforms to human face, the helmet are allowed preferably to be fixed on human body head
On, and when needing to adjust the length of fixing belt 14 to play better fixed function, it only need to be in main belt mobile in passive belt 141
142, it is clamped the jumping bean spring 143 in main belt 142 to different blocked holes 144.
The implementation principle of the present embodiment are as follows: when putting on crash helmet, rotate fixing belt towards the position far from cap shell 1 first
14, it is placed in cap shell 1 on head, the rotation of fixing belt 14 will drive the rotation of the second torsional spring 15, and the rotation of the second torsional spring 15 can produce
Raw elasticity rotates fixing belt 14 towards cap shell 1 and abuts to face, so that the helmet is tentatively fixed on head by fixing belt 14.
Slide protection board 13 by sliding block 132 and sliding block 132, posterior neck hoop 12 be exposed, towards fixing groove 123 in move
Fixed strip 122, so that the size of cap hoop 11 changes, the size of cap hoop 11 is adjusted to suitable size, passes through hinge joint
Card adapter plate 124 is rotated towards fixed strip 122, card adapter plate 124 will drive the rotation of the first torsional spring 126, by the clamping of card adapter plate 124 to correspondence
Clamping groove 125 in, the first torsional spring 126 rotation generate elasticity will drive card adapter plate 124 towards far from fixed strip 122 position turn
It is dynamic, but in the clamping to clamping groove 125 of card adapter plate 124 after, card adapter plate 124 can not rotate back in protection block 121, so that clamping
Plate 124 fixes the position of fixed strip 122, finally slides protection board 13 again, covers up it by posterior neck hoop 12, so exist
In the use process of crash helmet, posterior neck hoop 12 can be prevented to be constantly exposed to outside, avoid posterior neck to a certain extent
Hoop 12 is damaged, and the service life of posterior neck hoop 12 is increased, to increase the service life of crash helmet.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
