Preferably, the mounting hole corresponds to the pin hole and the limiting groove on the lock core respectively.

Preferably, the groove is arc-shaped and corresponds to the curved surface of the lock cylinder.

Preferably, the limiting groove is semicircular.

Preferably, the lock core, the upper pin tumbler and the lower pin tumbler are made of copper.

Compared with the prior art, the utility model provides a padlock possesses following beneficial effect:

1. the padlock has no lock tongue structure design, the lock cylinder is directly buckled with the lock beam, the padlock is simple in structure, manufacturing materials and cost are saved, meanwhile, the lock cylinder is not easy to damage, and an anti-theft effect is achieved.

2. According to the padlock, the lock cylinder, the upper pin tumbler and the lower pin tumbler are made of copper, and the lock cylinder cannot rust and cause necrosis after being used for a long time.

The part that does not relate to among the device all is the same with prior art or can adopt prior art to realize, the utility model discloses the padlock, simple structure, the lock core is difficult for rustting the necrosis and suffers destruction, plays the theftproof effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-6, in order to achieve the above purpose, the present invention adopts the following technical solutions:

a padlock comprises a lock body 1, a lock beam 3 and a lock cylinder 2, wherein one end of the lock beam 3 is rotatably connected into the lock body 1, a groove 11 is formed in the other end face of the lock beam 3, a mounting hole 10 is formed in the bottom of the lock body 1, a marble hole 7 and a limiting groove 8 are formed in the lock cylinder 2, an upper marble 5 and a lower marble 4 are respectively mounted in the marble hole 7 from top to bottom, a limiting column 6 is mounted in the limiting groove 8, the limiting column 6 is connected with the lock cylinder 2 through the limiting groove 8, a key positioning groove 9 is formed in the lock cylinder 2, the mounting hole 10 corresponds to the marble hole 7 and the limiting groove 8 in the lock cylinder 2, the groove 11 is arc-shaped, the groove 11 corresponds to a curved surface of the lock cylinder 2, the limiting groove 8 is semicircular, and the lock cylinder 2.

The utility model discloses padlock theory of operation:

the utility model discloses the padlock, during the installation, will go up marble 5 and during marble 4 inserts mounting hole 10 down, seal mounting hole 10 again, when unblanking, the key inserts behind the key constant head tank 9, because the key tooth pitch corresponds the tooth depth one by one with marble hole 7 and marble 4 length is corresponding down, therefore make the contact surface of going up marble 5 and lower marble 4 just in time coincide with the contact surface of lock core 2 with lock body 1 mutually, lock core 2 consequently can the free rotation, realize unblanking shutting, spacing post 6 contacts with 8 one end of spacing groove on the lock core 2, be used for restricting 2 rotations of lock core.
