Specific embodiment

As shown in figure 1, two-part automotive engine hood lock described in the utility model, including the lock being fixedly arranged on inside bonnet Body installing plate 1, according to the construction featuress of existing car engine cabin, lock body installing plate 1 is installed on bonnet leading inside plate face On；The left riveting axle 2 being parallel to each other and right riveting axle 3 are provided with lock body installing plate 1, activity riveting on right riveting axle 3 has ratchet 4, On left riveting axle 2, activity riveting has and 4 two grades of ratchets 5 engaging of ratchet, and, along right riveting axle 3 axial rotation, ratchet 5 is along left riveting for ratchet 4 Axle 2 axial rotation；With the ratchet 4 of ratchet 5 opposite side in the middle part of be provided with the upper fixture block 6 of outwardly convex and lower fixture block 7, upper fixture block 6 and lower fixture block 7 linking lay, stepped；It is respectively arranged with upper fixture block 6 and the lower card with ratchet 4 in ratchet 5 upper end and middle part Upper clamping hook 8 and lower stuck point 9 that block 7 activity is engaged by clamping；Be provided with the lock body installing plate 1 in ratchet 4 left side with ratchet 4 under The ratchet extension spring 10 that end is connected, is provided with, on the lock body installing plate 1 on ratchet 5 right side, the ratchet being connected with ratchet 5 lower end and draws Spring 11；The ratchet 4 lower end power that applying turns left is given in ratchet extension spring 10, and pawl tension spring 11 to ratchet 5 lower end to apply to turn right Power, thus ensureing the joggled strength of ratchet 4 and ratchet 5 so as to tightly engage；Under the ratchet 5 of pawl tension spring 11 opposite side End is connected with bonnet switch guy wire 12, and the other end of bonnet switch guy wire 12 connects the bonnet switch in car cage.

Course of action of the present utility model is as follows：

As shown in figure 1, Cover lock for engine is in lockup state, now the upper fixture block 6 of ratchet 4 and the lower stuck point 9 of ratchet 5 are in spine Tightly engage it is ensured that bonnet is in the completely closed state all the time under wheel extension spring 10 and pawl tension spring 11 opposite effect power.

When first time pulling bonnet switch, as shown in Fig. 2 bonnet switch guy wire 12 traction ratchet 5 lower end, make spine Pawl 5 lower end turns left（I.e. ratchet 5 rotates forward）, the lower stuck point 9 of ratchet 5 departed from the upper fixture block 6 of ratchet 4；In pawl tension spring 11 Under the pulling force effect to the left of pulling force and ratchet extension spring 10 to the right, it is tight with the lower fixture block 7 of ratchet 4 that lower stuck point 9 crosses fixture block 6 Engagement, now bonnet is in one-level released state.

When pulling bonnet switch again, as shown in figure 3, bonnet switch guy wire 12 draws under ratchet 5 again to the left End, makes ratchet 5 lower end turn left again（I.e. ratchet 5 rotates forward）, the lower stuck point 9 of ratchet 5 departed from the lower fixture block 7 of ratchet 4；Now The upper clamping hook 8 of ratchet 5 turns right, under pawl tension spring 11 pulling force and ratchet extension spring 10 to the right pulling force effect to the left, on Snap fit 8 tightly engages it is ensured that ratchet 4 will not completely disengage from out with ratchet 5 with the upper stuck point of ratchet 4, and bonnet is in two grades of solutions Lock status, that is, bonnet fully open.
