Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1

Referring to fig. 1 to 3, the lockset for the double-door includes a lock body 1 and a lock catch 2, wherein the lock body 1 includes a housing 8, a rotating seat 9, a rotating shaft 10, a pin shaft 14 and a bolt 3.

Referring to fig. 4, the rotating base 9 is rotatably connected in the housing 8 through a rotating shaft 10, wherein the rotating shaft 10 may be made of square steel or cylindrical steel, and the handles 5 are respectively mounted at two ends of the rotating shaft 10.

The lower end of the rotating seat 9 is provided with a boss 18, and a first torsion spring 12 for elastically resetting the rotating seat 9 is arranged between the rotating seat 9 and the shell 8.

Referring to fig. 5, the two lock tongues 3 are symmetrically distributed, the two lock tongues 3 are rotatably connected in the housing 8 through a pin 14, and a second torsion spring 13 is further installed between the two lock tongues 3.

The lock tongue 3 is provided with a longitudinal force arm 20 and a transverse force arm 21, the longitudinal force arm 20 is in contact with the boss 18, the tail end of the transverse force arm 21 is provided with a hook 22, and the shell 8 is further provided with a through groove 4 for the hook 22 to go in and out.

The lock catches 2 are a pair, and hook grooves 6 matched with the hooks 22 are symmetrically formed in the pair of lock catches 2.

The working principle is as follows:

locking: the lock catch 2 and the lock body 1 are respectively arranged on a sliding door and a door frame, and the sliding door is pushed to enable the hook 22 to enter the lock catch 2, so that locking is completed.

Unlocking: the rotating handle 5 drives the rotating seat 9 to rotate, and the boss 18 on the rotating seat 9 pushes the bolt 3 to rotate along the pin shaft 14, so that the hook 22 rotates downwards to be separated from the lock catch 2, and unlocking is completed.
