Detailed Description
The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.
Example 1
A luggage compartment door lock comprises a lock tongue 1, a lock shell 2, a lock cylinder 3, a lock spring 4, a limit rod 5 and an electromagnetic lock 6;
a lock cylinder 3 is arranged in the lock shell 2, a lock tongue 1 is arranged on one side of the lock cylinder 3, and the lock tongue 1 is matched with the lock cylinder 3 in structure;
the lock cylinder 3 is provided with a limit groove 7, a limit step 16 is arranged in the limit groove 7, one side of the lock cylinder 3 is provided with a limit rod 5, one end of the limit rod 5 is connected with the limit groove 7, and the other end of the limit rod 5 is connected with the lock shell 2; in operation, the limiting rod 5 takes one end connected with the lock shell 2 as a fulcrum, the other end of the limiting rod 5 moves in the limiting groove 7, a limiting step 16 is arranged in the limiting groove 7, and the limiting step 16 enables the limiting rod 5 to move along a set movement direction.
An electromagnetic lock 6 is arranged on one side of the limit groove 7; the electromagnetic lock 6 is used for limiting the movement of the limiting rod 5 when the locking is needed.
A spring piece 8 is arranged on the other side of the lock cylinder 3, and a latch 9 is arranged on the spring piece 8; the spring plate 8 is made of elastic materials, a clamping groove 10 is formed in one side of the lock tongue 1, and the clamping teeth 9 are matched with the structure of the clamping groove 10 to limit the lock tongue.
One end of the lock cylinder 3 is connected with the lock shell 2 through a lock spring 4, and the lock spring 4 is used for resetting the lock cylinder 3.
The limiting rod 5 can be driven by the adjusting spring 11 to move along the set collection;
the inner wall of one side of the lock shell 2 is provided with a chute 12, the structure of the chute 12 is matched with the bottom structure of the lock cylinder 3, and the lock cylinder 3 can slide on the chute 12 to reciprocate, so that the locking function is realized.
One side of the chute 12 is provided with a limiting plate 13, and the limiting plate 13 is used for limiting the movement range of the lock cylinder 3.
One side of the elastic sheet 8 is provided with a limiting block 14, and the limiting block 14 can limit the position of the elastic sheet 8.
