Description

Technical Field

[0001] The utility model relates to the field of padlocks, in particular to a rust-proof padlock with a lock core protection structure. Background Art

[0002] As a security tool, padlocks are common in daily life because of their simple operation, durability and affordable price.

[0003] Existing padlocks, such as the one disclosed in ZL202120366190.4, employ a permanent magnet at the end of the locking beam and a coil connected to a control chip at the locking beam hole to monitor the movement of the locking beam in and out of the locking beam hole, allowing the user to determine the unlocked status of the padlock. However, this type of padlock has a significant gap within the locking beam hole leading to the lock core. Even when the locking beam is within the locking beam hole, there is sufficient clearance between the two. If exposed to water, water can easily flow through the gap to the lock core, causing the lock core structure to rust and rendering the padlock inoperable.

[0004] Therefore, the existing padlocks of this type have the problem of poor lock core protection effect. Utility Model Content

[0010] In the aforementioned rust-proof padlock with a lock core protection structure, a waterproof layer 17 is sleeved on the top of the lock body 1.

[0011] In the aforementioned rust-proof padlock with a lock core protection structure, an elastic waterproof sleeve 18 is arranged on the lock beam 2, and both ends of the elastic waterproof sleeve 18 are in a frustum shape.

[0012] Compared with the prior art, in the present utility model, by arranging an elastic plastic bayonet at one end where the slideway communicates with the lock beam hole, when the steel ball in the slideway is pushed by the pushing block on the lock core towards the lock beam hole, the elastic plastic bayonet is squeezed and deformed to generate an elastic force, tightly covering the periphery of the steel ball, achieving the sealing effect of the slideway, so that moisture cannot enter the lock core position through the slideway, and having a good protection effect on the lock core; by arranging a drying area communicating with the slideway and capable of placing a desiccant packet, and arranging a partition layer with a plurality of holes between the two, the desiccant packet can absorb the moisture in the slideway without affecting the sliding of the steel ball in the slideway, so that the slideway remains dry, and having a good protection effect on the lock core; by arranging a flip cover on the top of the drying area, the drying area can be opened to replace the desiccant packet to prevent the desiccant from failing, improving the rust-proof protection effect on the lock core; the groove arranged on the flip cover makes it convenient to open the flip cover.

[0013] In addition, by arranging a protection plate at the bottom of the lock body, the lock core part at the bottom of the lock body is isolated from the outside, preventing moisture from entering the lock core from the bottom of the lock body, and having a good protection effect on the lock core; by rotatably connecting the protection plate to the bottom of the lock body with an I-shaped shaft, the protection plate can rotate to shield and open the lock core at the bottom of the lock body, which is more convenient to use; by arranging a first permanent magnet around the lock core at the bottom of the lock body and a second permanent magnet on the protection plate, and using the mutual attraction of the first permanent magnet and the second permanent magnet, the protection plate stably shields the bottom of the lock body, improving the protection effect on the lock core.

[0014] By arranging water drainage channels at the bottoms of the two lock beam holes, the water entering the lock beam holes can be discharged in time through the water drainage channels, avoiding moisture from seeping into the slideway in the lock body to reach the lock core, and having a good protection effect on the lock core.

[0015] By arranging a detachable waterproof layer on the outer side of the lock body, most of the water can be blocked outside the waterproof layer, avoiding the lock body from rusting due to excessive contact with moisture, and having a good rust-proof effect.

[0016] By arranging an elastic waterproof sleeve with both ends in a frustum shape on the lock beam, when the lock beam is inserted into the lock beam hole, the frustum part of the elastic waterproof sleeve can tightly press above the lock beam hole to avoid moisture from entering the lock body.

[0017] Therefore, the utility model can not only better protect the lock core, but also has the advantage of better convenience. BRIEF DESCRIPTION OF THE DRAWINGS
