Concrete meaning in application.
The technical concept of the utility model is: on the basis of adjusting bandage using knob, adding coaxially connected with gear
Ratchet carry out limiting gear rotation, to prevent bandage from voluntarily loosening, meanwhile, the first guide post is set on adjusting knob, adjusts pine
Adjusting knob need to be only rotated when bandage can make the first guide post push cantilever deflection, make ratchet automatic unlocking that tune be allowed to lighten restrictions on
Band, easy to operate, one hand can be realized, moreover, by ratchet engage adjust bandage it is elastic, it is simple for structure, eliminate screw and
The handwares such as torsional spring, alleviate weight.
Fig. 1 to Figure 10 shows one embodiment that the application knob adjusts bandage device, referring to figs. 1 to shown in Figure 10,
It includes: shell (including front housing 200 and rear shell 600), bandage 500 and bandage with rack gear 502 that the knob, which adjusts bandage device,
500 meshed gears 400, the adjusting rotated with the coaxially connected ratchet 300 of gear 400 and drive ratchet 300 and gear 400
Knob 100.
As shown in figure 4, ratchet 300 is equipped with cantilever 301, the inner wall of shell (specially front housing 200), which is equipped with, adjusts claw
202, cantilever 301 and adjusting claw 202 cooperate, to limit ratchet 300 and the one-directional rotation of gear 400, prevent bandage 500 voluntarily
It loosens.Fig. 5 shows the schematic diagram that ratchet 300 prevents bandage 500 from voluntarily loosening, as shown in figure 5, when bandage 500 loosens automatically
When, it will drive gear 400 and rotate clockwise, engaged at this time due to cantilever 301 with claw 202 is adjusted, to prevent 400 turns of gear
Dynamic, i.e. prevention bandage 500 voluntarily loosens.
Adjusting knob 100 is equipped with the first guide post 101 of driving pawl 300, and the first guide post 101 can push cantilever
301 deformation adjust claw 202 to be detached from, so that 400 Double-directional rotary of ratchet 300 and gear is driven, to adjust the pine of bandage 500
Tightly.Fig. 6 shows the schematic diagram that adjusting knob 100 adjusts band 500 of lightening restrictions on, as shown in fig. 6, when rotating clockwise adjusting knob 100
When, the first guide post 101 will push cantilever 301 and generate deformation, thus make cantilever 301 to contract and adjust the disengaging of claw 202,
Allow to adjust band 500 of lightening restrictions on to make ratchet 300 become opening state.And adjusting knob 100 is rotated counterclockwise to tighten bandage 500
When, ratchet 300 does not generate interception.Therefore, pass through the singlehanded adjusting knob 100 for rotating the application bandage device, so that it may
Easily realize the elastic adjusting of bandage 500, it is easy to operate.

Equipped with the second guide post 102, the second guide post 102 is protruded into arc-shaped limit hole 302 to drive ratchet 300 to rotate.Setting second
The purpose of guide post 102 is more reliably to make adjusting knob 100 that ratchet 300 be driven to rotate, while also reducing the cantilever of ratchet 300
301 pressures prevent cantilever 301 to be broken, prolong its service life.Refering to what is shown in Fig. 3, in the present embodiment, the first guide post
101 and second guide post 102 be spaced identical, in fact can be used interchangeably.
In the present embodiment, with reference to shown in Fig. 5 and Fig. 6, the length in arc-shaped limit hole 302 meets: the second guide post 102 exists
In arc-shaped limit hole 302 when sliding, the first guide post 101 is located in the hook formation of cantilever 301 not deviate from, i.e., leads by second
To the position-limiting action of column 102, the relative motion of ratchet 300 and adjusting knob 100 is maintained at the length range in arc-shaped limit hole 302
Interior, the first guide post 101 will not deviate from from the hook formation of cantilever 301, so that there is no concern that the first guide post 101 is detached from cantilever
301 lose the effect for pushing 301 deformation of cantilever.
In the present embodiment, as shown in Fig. 2, bandage 500 is equipped with long hole 501, long hole 501 is equipped with rack gear 502, tooth on one side
Wheel 400 is engaged with rack gear 502 and is slided in long hole 501.Quicker in order to make to adjust, the bandage 500 in the present embodiment is right
It is provided with two, when adjusting knob 100 is rotated with moving gear 400 with claiming, while tightening or loosening two bandages 500.
The knob of the application adjusts bandage device and can assemble according to mode shown in Fig. 4, Fig. 7 to Figure 10: as shown in figure 4,
Adjusting knob 100, front housing 200 and ratchet 300 are assembled into front shell assemblies；According to shown in Fig. 7, after a bandage 500 is protruded into
Shell 600, and gear 400 is threaded through on the gear shaft of rear shell 600, then another bandage 500 is protruded into rear shell as shown in Figure 8
It 600 and is pressed in above the fluted disc of gear 400, thus shell component after being formed；Finally according to shown in Fig. 9, by front shell assemblies and rear shell
Component is connected together, and forms knob as shown in Figure 10 and adjusts bandage device.Wherein, gear 400 and ratchet 300 pass through buckle
Be fixed connection.
In the embodiment of the present application, the connection of each structure passes through clamping and realizes, simple for structure, easy to assembly and light-weight
Ingeniously.
Disclosed herein as well is a kind of helmet, which is equipped with as above described in any item knobs and adjusts bandage
Device, so as to which by the one-handed performance easily elastic adjusting of bandage, user experience is more preferably.
Above description is only a specific implementation of the present invention, under the above-mentioned introduction of the utility model, this field
