Description

Technical Field

[0001] This utility model relates to the field of padlock technology, and in particular to a heavy-duty padlock. Background Technology

[0002] Heavy-duty padlocks are a type of high-security lock made of steel, brass, or stainless steel. They feature a robust lock body, thick shackles, and are resistant to sawing, cutting, and prying. They can withstand several tons of pulling force and are suitable for high-protection scenarios such as warehouses, construction sites, and containers. Heavy-duty padlocks are widely used in industrial, logistics, and outdoor facilities to ensure the safety of property and equipment.

[0003] Heavy-duty padlocks used outdoors are exposed to harsh environments such as wind, sun, and rain for a long time. The lock cylinder and internal metal parts such as pins are prone to oxidation and rust due to rainwater penetration or humid air. Rust will reduce the smoothness of the lock, making it difficult to insert the key, causing the lock cylinder to jam, or even making it impossible to open. Therefore, a heavy-duty padlock is needed to solve the above problems. Utility Model Content

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides, for example Figure 1-4 The heavy-duty padlock shown includes a padlock body 1, a lock beam 2, two upper sealing mechanisms 3, and a sealing core mechanism 4. The lock beam 2 is installed on the top of the padlock body 1. The two upper sealing mechanisms 3 are symmetrically arranged above the padlock body 1. The upper sealing mechanisms 3 are used to prevent rainwater from entering the interior of the padlock body 1 from the top. The two upper sealing mechanisms 3 have the same structure. The sealing core mechanism 4 is arranged below the upper sealing mechanisms 3. The sealing core mechanism 4 is used to prevent rainwater from entering the interior of the padlock body 1 from the lock core.

[0041] The upper sealing mechanism 3 includes a sleeve ring 31 and a sealing ring 32. The sleeve ring 31 is fixedly sleeved on the outer wall of the lock beam 2, and the sealing ring 32 is fixedly connected to the bottom of the sleeve ring 31. The sleeve ring 31 and the sealing ring 32 are used to seal the gap between the lock beam 2 and the top hole of the padlock body 1.

[0042] The sealing mechanism 4 includes a fixed sleeve 41, a movable rod 42, a pressing disc 49, a strip-shaped sliding hole, a limiting slider 43, a return spring 44, a connecting disc 45, a rotating plate 46, a sealing plate 47, an arc-shaped limiting groove, a limiting rod 410, and a sealing element. The fixed sleeve 41 is fixedly connected to one side of the padlock body 1. The movable rod 42 is movably sleeved within the inner cavity of the fixed sleeve 41. The pressing disc 49 is fixedly connected to the top of the movable rod 42. The top of the pressing disc 49 has evenly spaced... The friction texture of the cloth increases the friction between the pressing disc 49 and the operator's fingers. A strip-shaped sliding hole is formed on the outer wall of the movable rod 42. A limiting slider 43 is slidably fitted into the inner cavity of the strip-shaped sliding hole and fixedly connected to the inner cavity of the fixed sleeve 41. The strip-shaped sliding hole and the limiting slider 43 limit the movement trajectory of the movable rod 42. One end of the return spring 44 is fixedly connected to the top of the limiting slider 43, and the other end of the return spring 44 is fixedly connected to the top of the inner wall of the strip-shaped sliding hole. The connecting circular plate 45 is fixedly connected to the bottom end of the movable rod 42. The return spring 44 can undergo elastic deformation, thereby driving the limit slider 43 and the movable rod 42 to automatically perform a reset movement. The rotating plate 46 is rotatably connected to the bottom of the connecting circular plate 45. The rotating plate 46 and the connecting circular plate 45 are rotatably connected through a rotating shaft. An arc-shaped limiting groove is opened at the bottom of the connecting circular plate 45. The limiting rod 410 is movably sleeved in the inner cavity of the arc-shaped limiting groove. The limiting rod 410 is fixedly connected to the top of the rotating plate 46. The arc-shaped limiting groove and the limiting rod 410 are used to limit the area where the rotating plate 46 and the sealing plate 47 can rotate. The sealing plate 47 is fixedly connected to one side of the rotating plate 46. A sealing element is set above the sealing plate 47. The sealing element is used to increase the sealing strength. The sealing element includes an annular groove and a sealing ring 48. The annular groove is opened at the bottom of the padlock body 1. The sealing ring 48 is fixedly connected to the inner cavity of the annular groove. Some structural components of the sealing mechanism 4 can be made of non-metallic materials.

[0043] Working principle of this utility model:

[0044] When the heavy padlock needs to be opened with a key, first apply a downward vertical force to the pressing plate 49 with your finger. The pressing plate 49 will cause the connecting plate 45, rotating plate 46, and sealing plate 47 to move downward vertically via the movable rod 42. When the sealing plate 47 can be easily rotated, rotate the sealing plate 47 away from the bottom of the lock cylinder. After rotating it away, remove the force applied to the pressing plate 49. Then the heavy padlock can be opened with the key. When the heavy padlock needs to be closed, remove the key, align the lock beam 2 with the hole at the top of the padlock body 1, and press the lock beam 2 downward until... When closed, the connecting ring 31 will squeeze the sealing ring 32, thereby sealing the gap between the lock beam 2 and the top hole of the padlock body 1. Then, the pressing round plate 49 drives the movable rod 42, the connecting round plate 45, the rotating plate 46 and the sealing core plate 47 to move vertically downward. After the sealing core plate 47 is rotated back to below the lock cylinder, the force of the pressing round plate 49 is removed. At this time, the pressing round plate 49 will squeeze the sealing ring 48 under the action of the return spring 44 to complete the purpose of sealing the lock cylinder, effectively preventing external rainwater from entering the interior of the heavy padlock and enhancing the waterproof performance of the heavy padlock.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
