Description

Technical Field

[0001] This utility model relates to the field of padlock technology, specifically a high-strength padlock with a replaceable lock cylinder. Background Technology

[0002] The padlock body is equipped with a ring-shaped or "I"-shaped metal bar that can be fastened, known as the "lock beam". This allows the padlock to be directly fastened to the lock body through the lock beam, forming a closed lock. The locking spring of the padlock pushes the locking ball forward under the action of elasticity, locking the lock cylinder, so that the lock cylinder will not fall out when unlocking. The lock hook is locked by a retaining spring, so the lock hook will not be ejected when unlocking. Most existing padlock cylinders cannot be disassembled and replaced.

[0003] To this end, the China Patent Network published a padlock with replaceable lock cylinder application number 202222014993.0. By setting a first telescopic elastic mechanism, the U-shaped hook body is moved. First, the two first sliders, which are respectively fixed to the two sliding rods, slide within the hollow column. At this time, the tension spring is pulled by the two first sliders, generating elastic force, which can adjust the distance between the U-shaped hook body and the main hook rod. A second telescopic elastic mechanism is set up. By pulling the lock hook head, the compression spring is moved, which in turn moves the second slider within the sleeve. At this time, the compression spring is compressed by the second slider, generating elastic force, which can adjust the distance between the lock hook head and the U-shaped hook body, thereby achieving length adjustment of the entire lock hook body. This facilitates locking different sized locking parts, enhancing practicality. Simultaneously, by setting a fixed magnetic ring and a sealing magnetic cover, the two are magnetically attracted and fixed, making opening and closing convenient and stable, and also providing waterproof protection for the keyhole.

[0004] While the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: when replacing the padlock cylinder, it is often necessary to use force to open the lock body or to disassemble the entire padlock to access the cylinder. Such operation is not only cumbersome and time-consuming, but may also cause unnecessary damage to the lock body shell, lock beam and other components in the process, affecting the overall structural stability of the padlock. Based on this, this utility model designs a high-strength padlock with a replaceable lock cylinder to solve the above problems. Utility Model Content
