As shown in Fig. 1 ~ Fig. 8, in the present embodiment, double wire drawings that 2 lower end of connecting rod is drawn to be equipped with to connect wire drawing connect
Head 2b and the first spring connector 2c for connecting the first spring 4.The 6 left end lower part of limiting plate be equipped with for the limit
The bayonet 6a of position 7 accurate fit of pin.
The operation principle of the present invention is as follows：
Hood lock is in Fig. 1, locking state shown in Fig. 2 during beginning, pulls wire drawing to the right for the first time, and wire drawing drives double draw
2 lower end of connecting rod moves right, make it is double connecting rods 2 is drawn to rotate counterclockwise, at this time ratchet 3 under the 2 upper stopper 2a effects of double drawing connecting rods, with
Double drawing connecting rods 2 interlock and enter Fig. 3, location status shown in Fig. 4.At the same time, the spacer pin 7 on ratchet 3 and limiting plate 6
On bayonet 6a contact engagements, prevent double to draw 2 lower end of connecting rod ratchet 3 has also entered extreme position from further pulling to the right.
At this point, the first ratchet slot 3a and the first claw hook 5b on pawl 5 on ratchet 3 is disengaged from, in second spring
Under effect, pawl 5 is rotated clockwise along the curved surface of 3 right edge of ratchet, is popped up, and the first claw hook 5b is nibbled with the first ratchet slot 3a
It closes, enters the location status shown in Fig. 5, Fig. 6, this state is an opening.So far, first time pulling action is complete
Into wire drawing is unclamped.
As shown in Figure 5, Figure 6, since pawl 5 pops up, the lower end of second claw hook 5c no longer holds out against limiting plate on pawl 5
6, limiting plate 6 rotates counterclockwise under the action of torsional spring 8；It has been unclamped additionally, due to wire drawing, double drawing connecting rods 2 are in the first spring 4
It is rotated clockwise under effect, rebound initial position, and the bayonet 6a of double spacer pins 7 drawn on connecting rod 2 and limiting plate 6, which also departs from, to be nibbled
It closes.At this point, wire drawing is pulled to carry out second of pull operation again, double drawing connecting rods 2 will drive ratchet 3 to rotate again, on ratchet 3
Second ratchet slot 3b is disengaged from again with the first claw hook 5b on pawl 5, and under the action of second spring, pawl 5 continues up time
Pin rotates, and pops up, enters Fig. 7, location status shown in Fig. 8, this state is secondary opening state.In this state
Under, ratchet 3 is completely disengaged with pawl 5 and engaged, and the latch hook 5a on pawl 5 no longer locks cover, and hood lock fully opens, so far,
Hood lock completes secondary pulling opening operation.
