Description

Technical Field

[0001] The utility model relates to the technical field of padlocks, in particular to a round steel padlock. Background Art

[0002] Round steel padlocks are commonly found in high-security environments such as warehouses, gates, and commercial facilities. Due to their unique design and strong materials such as hardened steel, they provide good resistance to prying and shearing. The design of this lock usually includes a heavy round shell and a central axis. Through this layout, the lock hook (usually hardened steel) can rotate in and out to provide physical locking.

[0003] Although traditional round steel padlocks perform well in terms of security, they often face some problems during long-term use, especially the problem of insufficient lubrication. The lack of an effective self-lubricating system means that the lock cylinder and other moving parts wear out over time and frequent use, making the lock difficult to operate or even completely ineffective due to rust or accumulated dirt inside the lock body. In addition, users need to manually lubricate these locks regularly, which not only increases the complexity and cost of maintenance, but also increases the cost of maintenance. This is particularly inconvenient for those used in harsh environments or occasions where regular maintenance is difficult. Utility Model Content

The auxiliary mechanism 2 is arranged inside the main body mechanism 1. The main body mechanism 1 includes a lock body 101. The lock body 101 is round and has a planar structure at the bottom. A lock hook 102 is arranged at the upper end of the lock body 101. A locking recess 103 is arranged inwardly at the lower end of the lock hook 102. An end piece 104 is arranged at the lower end of the lock hook 102. A lock hook hole 105 is arranged at the upper end of the lock body 101. A locking ball 106 is arranged inside the lock body 101. A locking device 107 is arranged at the right end of the locking ball 106. A first spring 108 is arranged inside the locking device 107. A lock core 109 is arranged on the lower side of the locking device 107. The lock body 101 provides a material for the entire lock. The lock hook 102 is a key component for realizing the locking function and is locked or unlocked by inserting into the lock body 101. The locking recess 103 helps to position the lock hook 102 inside the lock body and keep it in the correct position. The end piece 104 is fixed to the end of the lock hook 102 to provide additional structural support to prevent the lock hook 102 from breaking or deforming. The lock hook hole 105 is the track opening for the movement of the lock hook 102, so that the lock hook 102 can move in and out smoothly. The locking ball 106 moves inside the lock body 101 to lock or release the lock hook 102 and works in conjunction with the locking device 107. The locking device 107 controls the movement of the locking ball 106, and the elastic force is provided by the first spring 108 to quickly restore the locked state. The lock core 109 is the core of the unlocking mechanism.

[0023] A lock pin 110 is provided at the left end of the lock core 109, and a second spring 111 is provided at the left end of the lock pin 110. A lock hole 112 is provided at the bottom end of the lock body 101, and a key 113 is provided inside the lock hole 112. The auxiliary mechanism 2 includes a button 201, a button 201 is provided at the right end of the lock body 101, a limited end 202 is provided at the left end of the button 201, and a movable rod 203 is provided at the left end of the button 201. The lock pin 110 is directly controlled by the lock core 109 and is matched with the second spring 111 to ensure that it can automatically return to the initial position after each operation, thereby increasing the service life and reliability. The lock hole 112 is an interface for inserting the key 113, allowing the key 113 to interact with the lock core 109 to perform locking or unlocking actions.

[0024] The outer ring of the movable rod 203 is provided with a third spring 204, the left end of the movable rod 203 is provided with a liquid storage tank 205, and a push plate 206 is provided inside the liquid storage tank 205. The other end of the movable rod 203 is connected to the push plate 206, and the left end of the liquid storage tank 205 is provided with a lubricating liquid channel 207. The end of the lubricating liquid channel 207 is set next to the key 113. The button 201 allows the user to activate the built-in lubrication system. By operating the button 201, the push plate 206 can be driven by the movable rod 203. The movable rod 203 is wrapped with the third spring 204 to ensure that it can quickly return to the initial position after each press. The push plate 206 moves inside the liquid storage tank 205, squeezes the lubricating oil, and transports it to key parts inside the lock body, such as the lock core 109 and the lock hole 112 through the lubricating liquid channel 207. This self-lubricating mechanism simplifies the maintenance process, ensures that the lock maintains a good working condition during long-term use, and reduces failures caused by wear or rust.

[0025] Working principle: In this round steel padlock design, the main mechanism 1 and the auxiliary mechanism 2 work together to achieve locking and self-lubricating functions. The main mechanism 1 includes a lock body 101, which provides the basic structure for the entire lock. A lock hook 102 is provided at the upper end of the lock body 101, which cooperates with a locking recess 103 and an end piece 104 to realize the opening and closing of the lock. The lock hook hole 105 is a channel for the insertion and movement of the lock hook 102. The locking ball 106 is located in the lock body 101 and cooperates with the locking device 107 to control the locking and release of the lock hook 102. The locking device 107 is equipped with a first spring 108 inside, which is connected to the lock core 109. The lock core 109 interacts with the key 113 through the lock pin 110 and the second spring 111 to realize the unlocking action. The lock hole 112 is the position where the key 113 is inserted. The auxiliary mechanism 2 includes a button 201, which is arranged at the right end of the lock body 101 and is used to trigger the lubrication system. The button 201 is connected to the third spring 204 through the movable rod 203 to control the output of the lubricating oil in the liquid storage tank 205. The liquid storage tank 205 stores the lubricating oil and is connected to the push plate 206 and the lubricating liquid channel 207. When the button 201 is pressed, the movable rod 203 pushes the push plate 206 to squeeze the liquid storage tank 205, and the lubricating oil is sent to the lock core 109 and the lock hole 112 of the lock body 101 through the lubricating liquid channel 207, ensuring that the mechanical parts of the lock operate smoothly and reduce wear. This complete set of mechanisms not only ensures the safety and durability of the lock body 101, but also realizes automatic lubrication through the auxiliary mechanism 2, thereby enhancing the service life of the lock body 101 and the smoothness of operation.
