Technical Field
[0001] The utility model relates to a lock, in particular to a lock with good anti-pry effect. Background Art
[0002] Locks are generally divided into electronic locks and mechanical locks. Mechanical locks are widely used in applications that require long-term exposure to the external environment because of their mature technology and low price. Existing mechanical locks mainly use the locking beam and the locking structure in the lock body to cooperate with each other, use the locking beam to pass through the object to be locked, and then use the locking beam and the lock body to form a closed structure. In the actual use of padlocks, because the locking beam has a certain length and needs to ensure that the locking beam can move stably, there is a large space between the locking beam and the object to be locked, which makes it easy for outsiders to use pliers and other shearing tools to damage the locking beam, thereby making the lock lose its locking function and the anti-pry effect of the entire padlock is poor. Therefore, the existing padlocks have the problem of poor anti-pry effect. Utility Model Content

[0005] In the aforementioned lock with good anti-pry effect, a strip clip is provided at the end of the lock beam; an annular groove cooperating with the strip clip is provided at the bottom end of the inner side wall of the lock beam slot; the strip clip cooperates with the annular groove arranged on the lock beam slot, so that when locking the padlock, it is only necessary to rotate the lock beam. Compared with the previous structures using springs, marbles and tongue clips, the overall structure is simpler.
[0006] In the aforementioned lock with good anti-pry effect, the groove is a waist-shaped groove; the waist-shaped groove can provide enough space for placing the object to be locked, which is convenient for use.
[0007] In the aforementioned lock with good anti-pry effect, the distance between the inner bottom surface of the lock core channel and the inner bottom surface of the groove is smaller than the diameter of the lock beam.
[0008] In the aforementioned lock with good anti-pry effect, an anti-rust layer is sprayed on the outer surface of the shell; the anti-rust layer can increase the anti-rust ability of the entire shell, thereby extending the service life.
[0009] Compared with the prior art, the utility model designs a lock, by providing a groove on the shell, and the two side walls of the groove are respectively connected with a lock beam slot and a lock core channel, so that when the padlock is used, it is only necessary to put the place to be locked into the groove, and then slide the lock beam and the lock core into the lock core channel, so that the lock beam passes through the lock core channel, the groove and the place to be locked in turn, and finally enters the lock beam slot, and then the lock beam is rotated by the key so that the end of the lock beam is engaged with the lock beam slot, and the locking step can be completed. When the padlock is locked, the back of the whole padlock faces outward, that is, the opening of the groove faces the place to be locked, and the lock beam is hidden in the shell, so that there is space for outsiders to pry open the lock, thereby improving the anti-pry effect of the whole lock; at the same time, by providing a limiting member on the lock core channel, cooperating with the limiting groove arranged on the lock core, the limiting member can limit the movement of the lock core and prevent the lock core from detaching from the shell, thereby improving the stability of the structure. In addition, the utility model also provides a strip clamp at the end of the lock beam, which cooperates with the annular groove provided on the lock beam slot, so that when locking the padlock, it is only necessary to rotate the lock beam. Compared with the previous structures using springs, marbles and tongue clamps, the overall structure is simpler; by setting the groove as a waist-shaped groove, the waist-shaped groove can provide enough space for placing the object to be locked, which is convenient for use; by spraying an anti-rust layer on the outer surface of the shell, the anti-rust layer can increase the anti-rust ability of the entire shell, thereby extending the service life. Therefore, the utility model can not only improve the anti-pry ability, but also has the advantages of high structural stability, simple structure, long service life and service life.
