Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
By Fig. 1, Fig. 2 and Fig. 3 it is found that it is inside to define helmet close to the side on user head, far from user
The side on head is outside, this wear regulating mechanism include surrounding the shell of slideway, left bandage 21, be connected on left bandage 21 and
Be inserted into slideway in left bandage rack 22, right bandage 31 and be connected on right bandage 31 and from the slideway other end be inserted into slideway
Interior right bandage rack 32, in slideway and the transmission gear that is engaged respectively with left bandage rack 22, right bandage rack 32
41, the locking gear 42 for being coaxial therewith setting is fixedly connected on the side of transmission gear 41, is rotatablely equipped in slideway
Positioned at 42 side of locking gear and the pawl 51 that engages, torsion member is equipped between pawl 51 and slideway inside, in slideway
Switch 61 is inside installed, sliding connection structure is equipped between switch 61 and slideway, which includes plate body 62, is arranged on plate
The baffle 63 that is correspondingly arranged on body 62 and with pawl 51 and 42 engagement place of locking gear is arranged on plate body 62 far from locking gear 42
Button handsetting 64 on side is equipped with the shell elongated through-hole 12 connected with slideway on the shell, and it is elongated that button handsetting 64 is inserted into shell
In through-hole 12.
The operation principle for wearing regulating mechanism is explained as follows with reference to attached drawing：
It needs to adjust when wearing length, sliding button handsetting 64 along shell elongated through-hole 12 makes switch 61 be located at "On" state,
Baffle 63 is namely made to be moved to the side far from pawl 51, due to being equipped with torsion member between pawl 51 and slideway inside, is led to
Crossing to be pulled outwardly either inwardly pushes left bandage rack 22, the realization of right bandage rack 32 that will wear tune pine or tighten, left during adjusting
Relative motion between bandage rack 22, right bandage rack 32 makes transmission gear 41 rotate, and is rotated in transmission gear 41
Meanwhile locking gear 42 follows transmission gear 41 to rotate together, locking gear 42 often rotated a gear teeth, and pawl 51 is pushed
It is primary to be detached from locking gear 42, pawl 51 resets to locking gear 42 and engages under the twisting force of torsion member；Head is not adjusted
When wearing length, sliding button handsetting 64 along shell elongated through-hole 12 makes switch 61 be located at " lock " state, that is, make baffle 63 to spine
Pawl 51 moves and baffle 63 is made to snap at pawl 51, and pawl 51 is made to be constantly in the state engaged with locking gear 42, is locked at this time
Tight gear 42 will not rotate, and transmission gear 41 cannot also rotate, and left bandage rack 22, right bandage rack 32 are with passing
The position that moving gear 41 engages does not change, and can realize and wear length locking；It is simple in structure that this wears regulating mechanism, passes through
Outer drawing inwardly pushes left bandage 21, right bandage 31 to realize the adjusting for wearing length, and pawl 51 is in always and locking gear
The states of 42 engagements can prevent from wearing moment release, solve that helmet is complicated to be not easy to adjust and unclamp moment
Helmet can suddenly fall the problem of injuring face by a crashing object, adjusting can be facilitated to wear length, improve use reliability.
