Description

Technical Field

[0001] This utility model relates to the field of padlock technology, specifically an outdoor padlock with a keyhole protection structure. Background Technology

[0002] Padlocks are the oldest and largest family of locks in the world. It can be said that all other locks are derived from and developed from padlocks. The lock body of a padlock is equipped with a ring-shaped or "I"-shaped metal bar, also known as a "lock bar," which allows the padlock to be directly engaged with the lock body to form a closed lock.

[0003] In the prior art, a Chinese patent discloses a durable mechanical padlock (authorization announcement number CN222879468U). This patented technology enables the lock body to be limited in a bumpy environment during the locking process, avoiding collision with the contact surface of the vehicle body, effectively avoiding the drawbacks of the mechanical parts of the lock body being subjected to vibration and impact, thereby ensuring its mechanical structure and durability.

[0004] However, during use, the aforementioned padlocks may encounter sandstorms, causing sand and dust to enter the keyhole and become blocked, preventing them from opening. Therefore, an outdoor padlock with a keyhole protection structure is provided to solve the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this utility model is to provide an outdoor padlock with a keyhole protection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An outdoor padlock with a keyhole protection structure includes a padlock body, a lock beam on the padlock body, and a shielding structure below the padlock body. The shielding structure includes a shielding plate that can shield the keyhole of the padlock body.

[0008] As a further improvement of this utility model, a protective sleeve is fitted onto the upper part of the locking beam, and waterproof rings are fixedly connected to both ends of the protective sleeve.

[0009] As a further embodiment of this utility model: a movable sleeve is installed inside the bottom side of the padlock body, a rotating shaft is rotatably connected inside the movable sleeve, the rotating shaft is fixedly connected to the cover plate, and a spring is fixedly connected to the bottom side of the padlock body.

[0010] As a further embodiment of this utility model: a limiting block is fixedly connected to the rotating shaft, and a limiting half-ring is fixedly connected to the upper end of the movable sleeve. The limiting block and the limiting half-ring are mating components.

[0011] As a further improvement of this utility model, sealing gaskets are fixedly connected to the edges of the four sides of the shield.

[0012] As a further improvement of this utility model, the padlock body has sliding grooves on both sides, and a protective cover is slidably connected to the sliding grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By incorporating a shielding structure, the shielding plate within the structure, in conjunction with the spring, ensures that the shielding plate, without external force, will cover the keyhole on the padlock body, preventing dust from entering the keyhole and thus protecting the padlock body.

[0022] Please see Figures 1-5An outdoor padlock with a keyhole protection structure includes a padlock body 1, a lock beam 101 on the padlock body 1, a protective sleeve 2 fitted onto the lock beam 101, and waterproof rings 201 fixedly connected to both ends of the protective sleeve 2. The protective sleeve 2 fits onto the outside of the lock beam 101 to prevent rainwater from corroding the lock beam 101 and preventing the lock beam 101 from rusting. The waterproof rings 201 are located above the connection between the padlock body 1 and the lock beam 101. When the lock beam 101 and the padlock body 1 are locked, the waterproof rings 201 will cover the connection between the padlock body 1 and the lock beam 101 to prevent rainwater from falling into the interior of the padlock body 1.

[0023] like Figure 3 and Figure 5 As shown, a blocking structure 4 is provided below the padlock body 1. The blocking structure 4 includes a blocking plate 401, which can block the keyhole of the padlock body 1. A movable sleeve 404 is installed inside the bottom side of the padlock body 1. A rotating shaft 403 is rotatably connected inside the movable sleeve 404. The rotating shaft 403 is fixedly connected to the blocking plate 401. A spring 406 is fixedly connected to the rotating shaft 403 and the bottom side of the padlock body 1. A limit block 405 is fixedly connected to the rotating shaft 403. A limit half ring 407 is fixedly connected to the upper end of the movable sleeve 404. The limit block 405 and the limit half ring 407 are mating components. When the padlock body 1 is working (locked), the blocking plate 401 will block the keyhole on the padlock body 1 without external force. This prevents dust from entering the keyhole, thus protecting the padlock body 1. When unlocking is required, rotating the cover plate 401 causes the rotating shaft 403 to rotate on the spring 406, causing the cover plate 401 to shift at an angle and no longer block the keyhole, allowing the padlock body 1 to be opened with the key. After unlocking, when the key is removed, the cover plate 401 will return to its original position under the action of the spring 406. During this process, the spring 406 will drive the rotating shaft 403 to rotate. When the rotating shaft 403 rotates to a certain angle, the limiting block 405 will contact the limiting half-ring 407, which limits the rotation angle of the limiting block 405, i.e., the rotating shaft 403. At this time, the cover plate 401 is completely aligned with the bottom side of the padlock body 1, thus protecting the keyhole.

[0024] like Figure 1 and Figure 2As shown, sealing gaskets 402 are fixedly connected to the edges of the four sides of the cover plate 401. Sliding grooves 3 are provided on both sides of the padlock body 1. Protective covers 301 are slidably connected to the sliding grooves 3. When the cover plate 401 is completely overlapped with the bottom side of the padlock body 1, the protective cover 301 can be slid down to make the cover plate 401 inside the protective cover 301, so that the sealing gaskets 402 at the edges of the four sides of the cover plate 401 fit against the inner wall of the protective cover 301, thereby enhancing its sealing performance. This setting can play a role in preventing rainwater from entering the interior of the padlock body 1 through the lock cylinder, and preventing corrosion inside the padlock body 1.

[0025] Working principle: When the padlock body 1 is locked, the cover plate 401 covers the keyhole on the padlock body 1, preventing dust from entering the keyhole and thus protecting the padlock body 1. When unlocking is required, the cover plate 401 is rotated, causing the rotating shaft 403 to rotate on the spring 406. This causes the cover plate 401 to shift at an angle, thus no longer covering the keyhole, allowing the padlock body 1 to be opened with the key. After unlocking is completed and the key is removed, the cover plate 401 will return to its original position under the action of the spring 406. During this process, the spring 406 will drive the rotating shaft 403 to rotate. When the rotating shaft 403 rotates to a certain angle, the limiting block 405 will contact the limiting half-ring 407, which limits the rotation angle of the limiting block 405, i.e., the rotating shaft 403. At this time, the cover plate 401 is completely aligned with the bottom side of the padlock body 1, protecting the keyhole.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
