Embodiment 1

[0019] refer to figure 1 , a tumbler lock head, including a lock shell 2 and a lock cylinder 1, the lock shell is provided with an outer pin hole, the outer pin hole is built with a spring 102 and an outer pin 101, and the lock core is provided with The keyhole 3 and the inner pinhole arranged perpendicular to each other, the inner pinhole is arranged adjacent to the keyhole and communicates with it, the aperture of the inner pinhole near the keyhole end 103 is smaller than the aperture away from the keyhole end 6, and the large aperture The segment 6 is filled with inner pins 5 adapted to its size. In the initial state, the ends of the outer pins 101 extend to the holes of the inner pins.

[0020] The lock core is provided with a positioning bead 4, and the lock housing is correspondingly provided with a groove 104. In the initial state, the positioning bead is partly built into the groove, and the lock core and the lock housing are embedded through the positioning bead and t...

Embodiment 2

[0023] The guide rod is obliquely fixed to the fixed piece, and the movable piece is provided with a through hole for the guide rod to pass through. Others are the same as in the first embodiment.

Abstract

The invention provides a lock head of a spring lock. The lock head comprises a lock shell and a lock core; an external latch hole is formed on the lock shell; a spring and an external latch are arranged in the external latch hole; a key hole and an internal latch hole vertical to each other are arranged on the lock core; the internal latch hole is adjacent to the key hole and is communicated withthe key hole; the aperture of at one end of the internal latch hole close to the key hole is smaller than the aperture of the end away from the key hole; the big aperture section is filled with the internal latches matched with the size of the big aperture; the tail end of the external latch is extended in the latch hole at the initial state. According to the lock head and the matched key provided by the invention, the internal latches are hidden out of the key hole, so that the latches can not be seen on the key hole; when a key is inserted in the key hole, the latches are hidden, an unlock tool cannot dial the latches, the difficulty of technical unlocking is greatly increased, therefore, the burglar-proof function is improved.

Description

(1) Technical field [0001] The invention relates to an anti-theft lockset, in particular to a tumbler lock, which is suitable for products such as anti-theft doors, interior doors, safes, automobiles and motorcycles. (2) Background technology [0002] At present, there are mainly two types of pin lock cylinders commonly used in the market: one is punching key cylinder, and the other is milling key cylinder. The principle is the same. In the key channel (key hole) One or two rows of marbles of different lengths are distributed inside. When the key is inserted into the lock cylinder, the marbles match the key teeth, the lock cylinder can be rotated, and the lock can be opened. There are various lock cylinders on the market. Although the key slots are different and the number and shape of the pins are different, one thing is the same, that is, the pins are arranged on the key passage, and any lock that can be inserted into the keyhole Tools can move the marbles, which has buri...
