The specific embodiment
The pin-type load hood lock that present embodiment relates to, by as can be known shown in Figure 1, it comprises the upper lock body 11 that is arranged on the motor cover, be arranged on the down lock body 12 on the top rail of radiator stand by support, be connected with latch hook 2 what upper lock body 11 swung, be provided with the lockhole 21 that is complementary with latch hook at down lock body 12, latch hook 2 cooperates formation second gear lock with lockhole 21, when upper lock body 11 moves to down lock body 12, at first with upper lock body 11 and down lock body 12 lockings.Also be provided with one grade of lock between upper lock body 11 and down lock body 12, behind second gear lock locking, when upper lock body 11 continued motion to down lock body 12, this grade of lock was used for further locking upper lock body 11 and down lock body 12.
In one grade of lock construction in the present embodiment, it comprises the master lock pin 31 of the pin-type load that is connected with upper lock body 11, be movably installed with the piece 32 of upspringing at master lock pin 31, be set with the return spring 33 that elastic force is provided when one grade of unlatching is locked at the master lock pin 31 of upspringing between piece 32 and the upper lock body 11, be integrally formed with tapered end 34 in the bottom of master lock pin 31, tapered end 34 whole one-tenth are inverted round table-like, it is positioned at the base area of top greater than the end face diameter of master lock pin 31, and the cross-sectional area of the piece 32 of upspringing also is greater than tapered end 34 upper end face areas.Be provided with the only via hole that passes through of lock bodies 34 at down lock body 12, after lock body 34 connects via holes, because the large top that is blocked in down lock body 12 of the area of the piece 32 of upspringing.Soffit at down lock body 12 is connected with for the lock core that the tapered end after connecting down lock body 12 is carried out locking.
Lock core structure in the present embodiment as shown in Figure 4, it comprises by the first rotating shaft 61 and is rotatably connected on two lock core chips 4 on the down lock body 12, be fixedly installed on two lock core chips 4 are opened/the mutual opening mechanism of closed procedure relatively on the down lock body 12, be provided with respectively two semicircular through holes at the opposite edges place of two lock core chips 4, when these two semicircular through holes are two lock core chip 4 relative motions and mutually closed, form the through hole 41 of a circle, the diameter of this through hole 41 is less than the diameter of tapered end 34 upper surfaces, and greater than the end face diameter of master lock pin 31, so that two lock core chips 4 after the mutual closure move upward tapered end 34 pintle hook locks to prevent tapered end 34.Before realizing tapered end 34 pintle hook locks, guarantee that tapered end 34 is positioned at the below of two lock core chips 4, therefore, realize above-mentioned purpose in order to make tapered end 34, when two lock core chips 4 opened relatively, it is large that the aperture of through hole 41 becomes, and namely guaranteed passing through of tapered end 34.Therefore, need to provide an opening mechanism realization that two lock core chips 4 are had relatively opens/mutual closed motion action.
The opening mechanism of present embodiment comprises the first start arm 51 and the second start arm 52 that is hinged on respectively on two lock core chips 4, and the free end of the first start arm 51 and the second start arm 52 is rotationally connected by the second rotating shaft 62, be connected with the backguy haulage gear at the first start arm 51, this opening mechanism comprises be connected and the baffle plate 71 of one-body molded manufacturing vertical with the first start arm 51, backguy 72, the spacing ball 73 that is positioned at baffle plate 71 left ends and is connected with the backguy 72 that connects baffle plate 71, by the draw operations to the right to backguy 72, and then drive spacing ball 73 promotes baffle plate 71 positive motions to the right, because the first start arm 51, the structure setting of the second start arm 52 finally makes two lock core chips 4 carry out relative opening movement take the first rotating shaft 61 as axle.For realizing the mutually motor performance of closure of two lock core chips 4, be fixed with torsion spring in the first rotating shaft 61, when external force pulling backguy caused two lock core chips 4 to be opened, the torsion spring accumulation of energy was rotated in the first rotating shaft 61; When external tensile force disappeared, the first rotating shaft 61 rotated back into original position under the effect of torsion spring, and two lock core chips 4 reappear again closed.
When carrying out locking, the cover of motor is pressed downwards, at first latch hook 2 is introduced in the lockhole 21, and the second gear of hood lock is locked at first locking, and its state is as shown in Figure 2; At this moment, cover continues, and after the tapered end 34 of one grade of lock connects down lock bodies 12, forces two lock core chips 4 are opened, make tapered end 34 become through hole 41 after large by diameter fully after, two lock core chips 4 are mutually closed, tapered end 4 pintle hook locks the most at last, state is as shown in Figure 3.In this process, return spring 33 compressed and accumulation of energy under the effect of the piece 32 of upspringing.
When opening, by external force pulling backguy, and then two lock core chips 4 are opened relatively, when through hole 41 has the change major diameter of passing through for tapered end 34, because the effect of return spring 33, tapered end 34 is upspring, tapered end 34 is moved upward and finish after one grade of lock opens by the via hole on the down lock body 12, apply external force by giving latch hook 2, directly make latch hook 2 break away from lockholes 21, whole hood lock is opened, and its state as shown in Figure 1.
Present embodiment minute is arranged one grade of lock and second gear lock, has guaranteed the intensity of hood lock, simultaneously opening mechanism is close to the lock body setting, and is enclosed in the cabin, opens hood lock thereby stopped other people by tearing backguy, vehicle is implemented the behavior of theft.
