Description

Double-pulling-out cover lock

Technical Field

The utility model relates to a two lock of pulling out hair cover.

Background

At present, the engine hood lock provided in the market firstly pulls a guy cable to open a first section of the engine hood lock in a vehicle, then manually pulls a handle of an engine hood safety lock to open a second section of the engine hood lock at the front section of the engine hood, and the engine hood can be completely opened.

Disclosure of Invention

In view of the deficiency of the background art, the technical problem to be solved by the utility model is to provide a double-pulling-out cover lock which is more convenient to open.

Therefore, the utility model discloses an adopt following technical scheme to realize:

two cage locks of pulling out, including lock body and clamp plate, but be equipped with intermeshing's lock leaf and pawl between lock body and the clamp plate, be equipped with lock leaf round pin axle and first pawl round pin axle on the clamp plate, the lock leaf cover is located on the lock leaf round pin axle and the lock leaf round pin cover is equipped with the clockwise pivoted lock leaf torsional spring of messenger's lock leaf, first pawl round pin epaxial is located to the pawl cover, and the cable, characterized by are connected in the pawl outside: the lock is characterized in that a first lug and a second lug which are meshed with the locking pawl are arranged on the lock leaf, a second locking pawl pin shaft and a torsion spring are arranged on the lock body, a limiting block which is meshed with the locking pawl in an involute manner is sleeved on the second locking pawl pin shaft, the limiting block can be meshed with the first lug and the second lug respectively, the torsion spring is provided with two rotating centers, the first locking pawl pin shaft and the second locking pawl pin shaft are sleeved with the torsion spring respectively, one end of the torsion spring is hooked on the locking pawl to enable the torsion spring to rotate anticlockwise, and the other end of the torsion spring is hooked on the limiting block to enable the torsion spring.

After the technical scheme is adopted, when the engine hood needs to be opened, the stay cable is pulled to drive the locking claw to rotate clockwise to enable the locking claw to be separated from the first convex block of the lock leaf, the lock leaf rotates clockwise under the action of the lock leaf torsion spring, meanwhile, the rotation of the locking claw can drive the limiting block to rotate anticlockwise and block the first convex block to complete one-section unlocking, then the stay cable is loosened, the locking claw and the limiting block respectively rotate anticlockwise and rotate clockwise to return under the action of the torsion spring, at the moment, the locking claw is meshed with the second convex block, then, the stay cable is pulled for the second time to drive the locking claw to rotate clockwise to enable the locking claw to be separated from the second convex block, the lock leaf rotates clockwise under the action of the lock leaf torsion spring, meanwhile, the limiting block can drive the limiting block to rotate anticlockwise and block the second convex block to complete.

Drawings

The utility model discloses there is following figure:

fig. 1 is a schematic perspective view of the present invention;

fig. 2 is the schematic structural view of the utility model with the pressing plate, the lock leaf torsion spring and the torsion spring removed.

Detailed Description

Referring to the above-mentioned attached drawings, the utility model provides a two cover locks of pulling out includes lock body 1 and clamp plate 2, but be equipped with intermeshing's lock leaf 3 and locking claw 4 between lock body 1 and the clamp plate 2, be equipped with lock leaf round pin 5 and first locking claw round pin axle 6 on the

clamp plate

2, 3 covers of lock leaf are located on lock leaf round pin 5 and the cover is equipped with and makes 3 clockwise pivoted lock leaf torsional springs 7 of lock leaf on the lock leaf round pin 5, first locking claw round pin is located to locking claw 4 covers on 6, and the cable is connected in the 4 outside of locking claw, characterized by: be equipped with on the lock leaf 3 with the first lug 8 and the second lug 9 of pawl 4 meshing, be equipped with second pawl round pin axle 10 and torsional spring 11 on the lock body 1, the cover is equipped with the stopper 12 with pawl 4 involute meshing on the second pawl round pin axle 10, and stopper 12 can mesh mutually with first lug 8 and second lug 9 respectively, torsional spring 11 has two rotation centers, overlaps respectively and establishes on first pawl round pin axle 6 and second pawl round

pin axle

10, and 11 one end of torsional spring colludes and makes its anticlockwise rotation, the other end collude and make its number clockwise rotation on stopper 12 on pawl 4.

In this embodiment, when the engine hood needs to be opened, the cable is pulled to drive the stopping claw 4 to rotate clockwise to separate from the first lug 8 of the lock leaf 3, the lock leaf 3 rotates clockwise under the action of the lock leaf torsion spring 7, meanwhile, the rotation of the stopping claw 4 can drive the limiting block 12 to rotate counterclockwise and block the first lug 8, one-section unlocking is completed, then the cable is loosened, the stopping claw 4 and the limiting block 12 respectively rotate counterclockwise and rotate clockwise to return under the action of the torsion spring 11, at this time, the stopping claw 4 is engaged with the second lug 9, then the cable is pulled for the second time to drive the stopping claw 4 to rotate clockwise to separate from the second lug 9, the lock leaf 3 rotates clockwise under the action of the lock leaf torsion spring 7, meanwhile, the rotation of the stopping claw 4 can drive the limiting block 12 to rotate counterclockwise and block the second lug 9, two-section unlocking is completed, and the engine hood can be opened by, the operation is more convenient.
