Abstract

The present invention provides an U-shaped lock which mainly composed of an outer casing, an inner main body, a lock cylinder, two link members, two latch bars, and a lock shackle. The internal main body is configured in the receiving chamber of the outer casing, and the lock cylinder is mounted in a groove of the internal main body. A driving block is displaced in the rotor of the lock cylinder. Two link members are arranged, opposite to each other, in two grooves formed in the internal main body. Positioning guide tabs of the link members are received respectively in guide slots of the internal main body. Stop tabs of the link members are installed at two sides of the driving block. The two latch bars and the two engaging tabs of link members are mutually embedded to be coupled each other. The two latch bars are received in sliding channels formed in the internal main body. The lock shackle is inserted into the aligned through holes of the outer casing and the pin insert jack facing the internal main body. As such, switching the rotor of the lock cylinder drives the driving block to rotate and abuts the two latch bars to move outward so that the two latch bars are moved outwards in opposite directions. The two ends of the lock shackle can be firmly and securely locked with such a simple structure to achieve the best effect of anti-theft.

Description

U-lock

The invention relates to a U-shaped lock, in particular to rotating the lock block by rotating the lock core to push the two-clip rod to move outward or inward, and the two-clamp rod is relatively outwardly moved to be stable. And it does lock the two ends of the hook to achieve the best anti-theft effect.

Press, the general locomotive lock 1, please refer to the first figure, mainly provided with a body 10, a U-shaped lock rod 11, a lock core 12, a lock pin 13, a spring 14 and a pivotal member 15 The slot 10 is disposed at one end of the body 10, and one end 110 of the U-shaped lock lever 11 is disposed in the slot 100, and is pivoted by the pivoting component 15, and the other end of the body 10 is provided with a slot 100.
