Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
The present embodiment provides a kind of intelligent helmet, the elastic band including helmet body and positioned at the inside of helmet body.Such as
Shown in Fig. 1, elastic band includes adjuster 1 and rack band 2, and the first end of rack band 2 and the top of the gear 1032 of adjuster 1 are nibbled
It closes, the second end of rack band 2 is engaged with the lower part of the gear 1032 of adjuster 1.
As shown in Fig. 2~Fig. 6, adjuster 1 includes:Outer cover 101, inner lid 102, rotating card block 103 and hub cap 104.Outer cover
101 include the ring gear 1011 that inner ring is equipped with double wedge;Rotating card block 103 includes the flap 1031 being located in ring gear 1011 and positioned at outer
(inner lid 102 is located at side of the outer cover 101 far from flap 1031, gear to the gear 1032 of side of the lid 101 far from ring gear 1011
1032 are located in the cavity that outer cover 101 is formed with inner lid 102);Flap 1031 includes at least four strips, and strip is inserted into ring gear
In 1011 tooth socket;Hub cap 104 is rotatablely connected with ring gear 1011, and flap 1031 is between outer cover 101 and hub cap 104;Hub cap
104 are equipped with convex block close to the side of flap 1031, and convex block is extended between two strips.Preferably, the quantity of strip is four.Card
Article include the first strip 10311, the second strip 10312,10313 and the 4th strip 10314 of third strip;First strip 10311
First partition 10315 is equipped between the 4th strip 10314, second is equipped between the second strip 10312 and third strip 10313
Partition board 10316.Convex block includes:First convex block 1041, between the first strip 10311 and first partition 10315;Second convex block
1042, between the second strip 10312 and second partition 10316;Third convex block 1043, positioned at third strip 10313 and
Between two partition boards 10316;4th convex block 1044, between the 4th strip 10314 and first partition 10315.
Specifically, when rotating clockwise hub cap 104, the first convex block 1041 pushes the first strip clockwise
10311 make the first strip 10311 be detached from tooth socket, and third convex block 1043 pushes third strip 10313 to make third clockwise
Strip 10313 is detached from tooth socket;Second convex block 1042 pushes second partition 10316 suitable so as to give flap 1031 clockwise
The power of hour hands rotation, the 4th convex block 1044 also push first partition 10315 suitable so as to give flap 1031 clockwise
The power of hour hands rotation.Final second strip, 10312 and the 4th strip 10314 rotates under the active force of convex block, rotation
During with the double wedge of ring gear 1011 friction and dislocation occurs, so as to send out the sound of " rattling away " and generate the hand of interim card
Sense;Gear 1032 rotates simultaneously, tightening rack band 2.When rotating counterclockwise hub cap 104, the second convex block 1042 is to side counterclockwise
To pushing the second strip 10312 that the second strip 10312 is made to be detached from tooth socket, the 4th convex block 1044 pushes the 4th card counterclockwise
Articles 10314 make the 4th strip 10314 be detached from tooth socket;First convex block 1041 push counterclockwise first partition 10315 so as to
Give the power that flap 1031 rotates counterclockwise, third convex block 1043 also push counterclockwise second partition 10316 so as to
Give the power that flap 1031 rotates counterclockwise.Final first strip 10311 and third strip 10313 are under the active force of convex block
It rotates, friction and dislocation occurs with the double wedge of ring gear 1011 during rotation, so as to send out the sound of " rattling away " simultaneously
Generate the feel of interim card;Gear 1032 rotates simultaneously, unclamps rack band 2.
Two strips in the setting of " eight " type are one group, and (the first strip 10311 and the second strip 10312 are one group, third
10313 and the 4th strip 10314 of strip is one group), two groups of (i.e. four) strips are shared in the present embodiment, can also set three groups
(i.e. the six roots of sensation), four groups (i.e. eight) or more strips.
In this present embodiment, adjuster 1 further includes cover board 105 and fixing bolt.Cover board 105 is located at hub cap 104 far from tooth
The side of ring 1011;Fixing bolt, side of the outer cover 101 far from rotating card block 103 sequentially pass through gear 1032, outer cover 101, turn
It is threadedly coupled after plate 1031 and hub cap 104 with cover board 105.Specifically, fixing bolt and cover board 105 realize ring gear 1011, rotation
Turn the positioning between fixture block 103 and hub cap 104, not only ensure that they will not be mutually disengaged, but also ensure that they can occur coaxially
Rotation.Further, side of the cover board 105 far from hub cap 104 is equipped with hex slot 1051.Specifically, it is inserted using allen wrench
Enter hex slot 1051, it is possible to realize being reliably connected for cover board 105 and fixing bolt.
" first " herein, " second " etc. have no special meaning just for the sake of being distinguish in description.
Additionally need statement, specific technical features described in the above specific embodiments, in not lance
It in the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the utility model is to each
The possible combination of kind no longer separately illustrates.
In addition, arbitrary combination can also be carried out between a variety of different embodiments of the utility model, as long as it is not disobeyed
The thought of the utility model is carried on the back, should equally be considered as content disclosed in the utility model.
