Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
Refer to shown in Fig. 1 ~ 3, it is the preferred embodiment of the utility model safeguard protection helmet 1, comprises cap body 2, head circumference adjusting device 3, disk body 4, elastic component 5, fastener 6, cover plate 7 and and rotates adjustment knob 8.
This cap body 2 is provided with a perforation 21, and the perforation 21 of cap body 2 is provided with unidirectional ratchet 22; This head circumference adjusting device 3 is a belt body, and be located at the inside of cap body 2 for circle, the two ends of belt body have opening 31,32 respectively, and the relative side of two openings 31,32 is respectively equipped with multiple latch 311,321.
Central projection one gear 41 of one end of this disk body 4, gear 41 respectively with multiple latches 311 of belt body both ends open 31,32,321 mutually meshing, the periphery of disk body 4 is provided with the hook part 43 that two arc-shaped limit grooves 42 being symmetrical in disk body 4 axle center and two are symmetrical in disk body 4 axle center, hook part 43 end is linked on disk body 4, front end, hook part 43 is formed and hooks shape and form a gap 44 with disk body 4, be provided with a projection 45 outside hook part 43, projection 45 clamping cap body 2 bore a hole 21 unidirectional ratchet 22.
This elastic component 5 is a spring, and one end of elastic component 5 presses on the central authorities of disk body 4, and the other end of elastic component 5 is located and pressed in the locating slot 61 of this fastener 6 one end co-axial recesses.This fastener 6 outline is in the form of annular discs, it is provided with linkage part 62 and one second holding section 63, this linkage part 62 is four short slots being formed at fastener 6 periphery, and the second holding section 63 axially extends protrusion by one end of fastener 6, and the periphery of the second holding section 63 is provided with multiple external tooth 631.
This cover plate 7 is incorporated on the outer surface of cap body 2, cover plate 7 has a circular locating openings 71, circular locating openings 71 is positioned on same axle center with the perforation 21 of cap body 2, have multiple internal tooth that can be mutually meshing with the external tooth 631 of the second holding section 63 in circular locating openings 71, this internal tooth is as the first holding section 72.
And one end of this rotation adjustment knob 8 is positioned coaxially in the circular locating openings 71 of cover plate 7, the end face rotating adjustment knob 8 is provided with an axially extended axis 81 and four axially extended projections.This axis 81 is fixed on cap body 2 with a screw after coaxially running through the opening 31,32 at fastener 6, elastic component 5, disk body 4 to belt body two ends, and the opening 31,32 at belt body two ends cannot be departed from by the restriction of axis 81.During enforcement, this projection is as actuator 82, after four corresponding four linkage part 62 through fastener 6 periphery of actuators 82 difference, then be each passed through two stopper slots 42 and two gaps 44 of disk body 4 periphery, to make rotation adjustment knob 8 interlock fastener 6 and disk body 4.
As shown in Figure 4, when elastic component 5 is the stretched condition of normality, the first holding section 72 and the clamping mutually of the second holding section 63, rotating adjustment knob 8 cannot rotate.And as shown in Figure 5,6, when user presses rotation adjustment knob 8 to make elastic component 5 in compressive state, the first holding section 72 is separated with the second holding section 63.When user rotates to a direction and rotates adjustment knob 8, the tip gap 44 hook part 43 being connected because of the drive of actuator 82 with disk body 4 reduces, and the projection 45 of hook part 43 suffers oppression and bullet card forward, and then drive disk body 4 rotates; And when rotating rotation adjustment knob 8 to other direction, front end, hook part 43 driven member 82 drives and reduces gap 44, and the projection 45 of hook part 43 departs from the restriction of single direction ratchet 22 and disk body 4 can be made to rotate.
For example, as shown in Figure 7, when user rotates rotation adjustment knob 8 to a direction, the latch 311,321 of head circumference adjusting device 3 both ends open 31,32 is made the two ends of head circumference adjusting device 3 to move relative to close direction by interlock, form the state of tightening up; And when user to other direction rotate rotate adjustment knob 8 time, the latch 311,321 of head circumference adjusting device 3 both ends open 31,32 made by interlock head circumference adjusting device 3 two ends with relative to away from direction move, form the state loosened.By this, namely can the gear 41 of disk body 4 drive head circumference adjusting device 3 to make in tightening or pine oil, thus adjustment head circumference adjusting device 3 be with the head circumference size of applicable user.
Therefore, the utility model has following advantage:
1, the utility model is when general state, allow the mutual clamping in the first holding section and the second holding section, to make rotation adjustment knob rotate, therefore, effectively can avoid rotating adjustment knob because of what do not expected and touch pushing rotation, allow head circumference adjusting device pine oil and cause the inconvenience in use.
2, the utility model when the elasticity adjustment not carrying out head circumference adjusting device, can allow and rotate adjustment knob energy strong fix and not rotating, and therefore, can extend product service life, and guarantee use safety.
In sum; according to content disclosed above; the utility model really can reach the object of expection; there is provided one can not only allow user easy to use, can increase the service life; and the safeguard protection helmet of use safety can be guaranteed; have the value that industry utilizes, whence proposes new patent application in accordance with the law.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
