When direction rotates, pressing plate 51 is inserted into card slot 311 and is rotated in a first direction with pawl 31, realizes synchronous rotary；When 5 edge of driving wheel
When second direction rotates, pressing plate 51 is detached from card slot 311, and elastic deformation occurs for band pawl 31, and pawl 31 receives the application of pressing plate 51
The power to axis direction, make 31 disengaged position of pawl, relieve above-mentioned the consolidating to pawl 31 of internal messing ratchet bracket 4
It is set for using, so that pawl 31 is rotated in a second direction,.In practical applications, since pawl group 3 includes multiple spine being uniformly arranged
Pawl 31, this make entire pawl group 3 receive that pressing plate 51 on driving wheel 5 applies to axis direction power when, uniform force,
It avoids pawl group 3 since forced position deviates or damages, improves the stability of pawl group 3.
In a preferred embodiment, as shown in figure 4, above-mentioned wears shell 1 further include: outer casing upper cover 11 and on shell
The shell lower cover 12 that lid 11 fastens, forms slideway, driving wheel 5 is set to outer casing upper cover between outer casing upper cover 11 and shell lower cover 12
11 outsides.In practical applications, the space that above-mentioned outer casing upper cover 11 and shell lower cover 12 are formed after fastening is above-mentioned slideway,
The outside of lid 11 on the shell is arranged in driving wheel 5, passes through with the pawl group 3 worn in the slideway formed in shell 1 and coaxially fixes
Connection, and rotate synchronously.
In a preferred embodiment, as shown in figure 4, above-mentioned wears regulating mechanism further include: bandage 6, bandage 6 include the
One bandage 61 and the second bandage 62, wherein the first bandage rack gear 71 being connected on the first bandage 61 in insertion slideway；Second ties up
With the second bandage rack gear 72 being connected on 62 in insertion slideway；Transmission gear 2 is tied up with the first bandage rack gear 71 and second respectively
Band rack gear 72 engages.Specifically, when transmission gear 2 is rotated in a first direction, the first bandage rack gear for being engaged with transmission gear 2
71 and second bandage rack gear 72 promoted into slideway, shorten and wearing the first bandage 61 outside regulating mechanism and the second bandage 62
Length wears turning down for size to realize；When transmission gear 2 is rotated in a second direction, engaged with transmission gear 2 first
Bandage rack gear 71 and the second bandage rack gear 72 are promoted to outside slideway, and the first bandage 61 and second outside regulating mechanism is being worn in increase
The length of bandage 62 is worn tuning up for size to realize, is realized to the flexible modulation for wearing length.
Below with reference to concrete application example, the course of work provided by the utility model for wearing regulating mechanism is carried out detailed
Thin explanation.
In practical applications, when user, which needs to shorten, wears length, it can be rotated in a first direction driving wheel 5, due to
Driving wheel 5 and pawl group 3 and transmission gear 2 are coaxial arrangements and rotate synchronously, to revolve with nutating gear 2 along first direction
Turn, so that the first bandage rack gear 71 and the second bandage rack gear 72 that engage with transmission gear 2 are promoted into slideway, shortens
The length of the first bandage 61 and the second bandage 62 outside regulating mechanism is worn, wears turning down for length to realize.
In practical applications, when user, which needs to increase, wears length, driving wheel 5 can be rotated in a second direction, due to
Driving wheel 5 and pawl group 3 and transmission gear 2 are coaxial arrangements and rotate synchronously that the pressing plate 51 on driving wheel 5 is in pawl group 3
Each pawl 31 apply the power to axis direction, to the center of the teeth directional pawl group 3 on pawl 31 can be pressed, to realize
The tooth of pawl 31 and the tooth on internal messing ratchet bracket 4 are detached from, to rotate in a second direction with nutating gear 2, and then are made
It obtains the first bandage rack gear 71 engaged with transmission gear 2 and the second bandage rack gear 72 is promoted to outside slideway, increase and wearing adjusting
The length of the first bandage 61 and the second bandage 62 outside mechanism wears tuning up for length to realize.
In practical applications, it when user's not rotating driver 5, is tied up with the first bandage 61 and second fixed in account
When band 62 is by external tensile force, transmission gear 2 will receive the power being rotated in a second direction, with each pawl in pawl group 3
31 are rotated in a second direction, but due to the prevention by the tooth on the handle ratchet wheel bracket 4 engaged with pawl 31, so that spine
Pawl 31 cannot be rotated in a second direction, and then the first bandage 61 and the second bandage 62 will not loosen, and realizing prevents head
The function that length is turned down is worn, so as to avoid helmet from the accidents such as injuring by a crashing object with occurring shaking or slide in account, is improved
The safety that helmet is worn.Further, since pawl group 3 has with internal messing ratchet bracket 4 in not rotating driver 5
One direction rotation characteristic, user can also be by the first bandage for will being separately connected with the first bandage 61 and the second bandage 62
Rack gear 71 and the second bandage rack gear 72 are manually advanced into slideway, to realize the adjusting to wearing length and turning down.
It is provided by the embodiment of the utility model to wear regulating mechanism by above-mentioned each component part, it realizes to wearing
The flexible modulation of length is worn in equipment, this is worn, and regulating mechanism is easy to operate with wearing, it is good to wear stability, in pawl group
Each pawl, which is uniformly arranged, can make entire pawl group be more uniformly stressed, and avoid pawl group off center position, extend
The long service life of regulating mechanism is entirely worn, and using the one-directional rotation characteristic of ratchet, pawl, passes through the pressure on driving wheel
The cooperation of plate and pawl group pawl is only capable of realizing by rotating driver so that wearing tuning up for length, can be to avoid wearing
There is the characteristics of shaking or sliding in equipment, and then improves the safety of helmet wearing.
Embodiment 2
The utility model embodiment provides a kind of helmet, as shown in figure 5, the helmet includes: head-wearing device
101 and embodiment 1 in wear regulating mechanism 102, wear regulating mechanism 102 and be set on head-wearing device 101, wear adjusting
Associated description in 102 particular content detailed in Example 1 of mechanism.It should be noted that above-mentioned in embodiments of the present invention wear
To be detachably connected between regulating mechanism 102 and head-wearing device 101, in practical applications, wears regulating mechanism 102 and wear dress
Setting, which can be between 101, is detachably connected, and is also possible to be fixedly connected, the present invention is not limited thereto.
By the cooperative cooperating of above-mentioned each component part, helmet provided by the embodiment of the utility model is realized
To the flexible modulation for wearing length on helmet, this, which wears regulating mechanism, has wearing easy to operate, long service life, wearing
Stability it is good and can avoid the occurrence of shaking or slide the characteristics of, and then improve helmet wearing safety.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
