An adsorption type lock comprises a lock bolt with an external thread, wherein the lock bolt is provided with a T-shaped groove along the axial direction of the lock bolt, the bottom of the T-shaped groove is fixedly connected with a magnet, an iron rotating block is in threaded connection with the vertical part of the T-shaped groove, one end of the iron rotating block, facing the notch of the T-shaped groove, is fixedly connected with a lock cylinder, and a stop block is arranged on the inner side wall of the lock cylinder;

the lock bolt is sleeved with a casing matched with the lock bolt, the upper end surface of the lock bolt along the axial direction is fixedly connected with a first bolt,

a fixed groove is formed in the fixed shell and is arranged above the lock bolt, the first bolt extends into the fixed groove, and a plurality of mounting blocks are fixedly connected to the upper portion of the fixed shell;

the iron rotating block faces one side of the bottom of the T-shaped groove and is fixedly connected with a plurality of second bolts, each second bolt penetrates through the lock bolt, and a plurality of clamping grooves matched with the second bolts are formed in the fixed shell.

Further limit, the lock cylinder is sleeved with an outer shell.

Further, the thread directions of the external thread of the lock bolt and the internal thread of the vertical part of the T-shaped groove are opposite.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the iron rotary block is adsorbed by the magnet when rotating to enter the T-shaped groove by arranging the magnet, so that the iron rotary block and the lock bolt are integrated, and when the iron rotary block is continuously rotated, the lock bolt also rotates together and drives the first bolt to enter the fixed groove, thereby realizing locking; when unblanking, at first rotatory piece of iron system for the fixed slot is deviate from to first bolt, then removes rotatory piece of iron system and makes the rotatory piece of iron system get into the juncture of the vertical part in T type groove and horizontal part, then rotatory piece of iron system, thereby realize the back-out of rotatory piece of iron system and second bolt, realize unblanking, and broken original only threaded connection or fixed connection, only need the mode of rotatory lock cylinder.

2. The outer shell is used for protecting the lock cylinder, the thread direction of the external thread of the lock bolt is opposite to that of the internal thread of the vertical part of the T-shaped groove, opening or locking of the lock bolt and the iron rotary block in different directions is achieved, and a conventional opening or locking mode is broken through.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Embodiments of the present invention include, but are not limited to, the following examples.

The technical scheme of the embodiment is as follows: an adsorption type lock comprises a lock bolt 6 with external threads, wherein the lock bolt 6 is provided with a T-shaped groove 10 along the axial direction of the lock bolt, the bottom of the T-shaped groove 10 is fixedly connected with a magnet 5, an iron rotating block 4 is in threaded connection with the vertical part of the T-shaped groove 10, one end, facing the notch of the T-shaped groove 10, of the iron rotating block 4 is fixedly connected with a lock cylinder 2, and a stop block 3 is arranged on the inner side wall of the lock cylinder 2;

a shell 8 matched with the lock bolt 6 is sleeved outside the lock bolt 6, a first bolt 7 is fixedly connected on the upper end surface of the lock bolt 6 along the axial direction,

a fixed groove 12 is formed in a fixed shell 11 and arranged above the lock bolt 6, the first bolt 7 extends into the fixed groove 12, and a plurality of mounting blocks 13 are fixedly connected above the fixed shell 11;

one side of the iron rotating block 4 facing the bottom of the T-shaped groove 10 is fixedly connected with a plurality of second bolts 14, each second bolt 14 penetrates through the lock bolt 6, and a plurality of clamping grooves 15 matched with the second bolts 4 are formed in the fixed shell 11. The outer shell 1 is sleeved outside the lock cylinder 2.
