The drawing of accompanying drawing is described as follows:
Fig. 1 is the plan view of the utility model embodiment.(side that shows safety cap)
Fig. 2 is the local amplification profile of blast switch among the utility model embodiment.
Fig. 3 is the detailed construction plan view of the utility model embodiment.
Fig. 4 is the top view of Fig. 3.
Fig. 5 is the local structure top view that the utility model form engages with rotating plate.
The utility model is described further below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model comprises a safety cap 1, and the zone of the approaching person of the attaching the names of pre-determined candidates ear in its both sides is provided with and shows a wherein example among the pivot seat 11(figure).There is a window 12 top of the leading edge middle section of safety cap 1.
Show one of them among the pair of pivot 13(figure), respectively be located on the pivot seat 11, the base portion 21 of openable form 2 is articulated on the safety cap, make the leading edge of form 2 can cover window 12.
One of feature of the present utility model is established one the hole 14 of blast switch 3 is installed, and make blast switch 3 roughly be positioned at the place ahead of the person's of attaching the names of pre-determined candidates mouth below safety cap 1 leading edge middle section 15.
Another feature of the present utility model is produced in two pivot seats 11 of safety cap 1 one, establishes power set 4.Power set 4 are detailed in Fig. 3 and Fig. 4, are articulated on the pivot 13 and rotating plate 41 that partial circle is moved but have one, with and action element.
Rotating plate is pulled spot and form base portion 21, is the mode with Fig. 5, borrows annular continuous recessed edge 211, and the device card that engages with salient point 411 is integrated, and form 2 can be rotated simultaneously with rotating plate 41 when rotating plate 41 rotations; Above-mentioned recessed edge and salient point all have suitable flexible, so when form is subjected to specially hand propelled, can produce relative slip (detailed aftermentioned) between each recessed edge and salient point.Certainly, also can consider salient point is located at the form base portion, and continuous recessed edge is located at rotating plate, its purpose is identical with aforementioned first kind of embodiment, all makes power set when promoting rotating plate 41, drives the pendulum or the bottom on the form 2 simultaneously.And when power set lost efficacy or do not have electricity, still can borrow the thrust of hand to make salient point 411 slip over each recessed edge 211 one by one, make hand can promote form smoothly.
As shown in Figure 3, above-mentioned power set also contain: a cell apparatus 5, be connected in motor 6 with output shaft 61, one deceleration device 7 by output shaft 61 drivings is arranged, and the cam ring 71 that its output 72 is fixed has circumference 711 and at least two elements that make limit switch 9 actions, the element of so-called action, in Fig. 3, be that local breach 71a and the 71b with the circumference of cam ring is example, still can there be other mode to constitute certainly.
Above-mentioned power set comprise a connecting rod 8 in addition, and its first end 81 is articulated in the circumferential area of cam ring 71, and 82 at its second end is articulated in the force side 412 of rotating plate 41.
Contact respectively with the action element 71a of aforementioned cam ring 71 or 71b and produce action, it is the switch element 91 of a limit switch 9, this limit switch is series at cell apparatus 5 and motor 6, that is its first utmost point is connected to cell apparatus 5 and motor 6 with second utmost point.
When blast switch 3 persons of being attached the names of pre-determined candidates blow and when making blast switch 3 closed circuit, but turn-on battery device 5 is to the circuit of motor 6, and motor 6 is rotated, drive cam ring 71 rotations, the switch element 91 of limit switch 9 is contacted with the circumference 711 of cam ring 71, and it is closed circuit to cause limit switch 9, makes cell apparatus 5 can borrow limit switch 9 to continue power supply and gives motor 6, to the switch element 91 of aforementioned limit switch 9 in the contact cam ring 71 one of them breach such as during 71a, just cut off circuit.Blown once again and during starter 6 to above-mentioned blast switch 3, the resume contacts circumference 711 of cam ring 71 of switch element 91, limit switch is closed again, make motor 6 continue energising, borrow cam ring 71 to promote connecting rod 8, is that the center produces oscillating motion and drive rotating plate 41 with pivot 13, and then makes the automatically contrary direction swing of form as imaginary line.This length by circumference 711 between the 71a of two breach and 71b forms the function of time-delay, can prevent that unexpected air blowing or air-flow or vibrations from making form do local rotation.
As Fig. 2, blast switch 3 comprises a pedestal 31, and has the wind hole 312 that disappears at most wind-engagings hole 311 and back, and the branch cloth cover in wind-engaging hole 311 preferably presents concave surface.
The utility model is exempted the inconvenience of motor vehicle knight with the hand propelled safety cap, and improves the safety of motor vehicle knight driving, in order to avoid the knight is because of opening or meeting accident during closed safe cap form.Blast switch of the present utility model and power set volume are also minimum, and be little with the volume and weight difference of safety cap in the past, is the safety cap that a more original safety cap has more security and convenience.
The above-mentioned explanation of the utility model, though the safety cap of being worn with the motor vehicle knight is an example, well-known, if the utility model is diverted on toy cap or other article also for feasible, therefore, claim of the present utility model should comprise the article of toy cap and application the utility model device thereof.
