Description

Technical Field

[0001] This application relates to the technical field of locks, and in particular to a waterproof padlock. Background Technology

[0002] A padlock is a portable lock that locks an object by "hanging" it.

[0003] In related technologies, reference can be made to Chinese Utility Model Patent No. CN208441634U, which discloses a padlock. The padlock includes a lock beam and a lock body. The lock body has a lock beam insertion hole. The padlock has a locked state and an unlocked state. The padlock also includes a circuit board housed within the lock body and a status switch housed within the lock beam insertion hole. The circuit board includes a controller connected to the status switch and an antenna connected to the controller. The antenna is used for wirelessly connecting the controller and a corresponding mobile terminal. The status switch is used to detect the status of the lock beam.

[0004] However, during use, the circuit board inside the lock body is easily damaged by rain and humidity when the padlock is hung outdoors, resulting in a shorter lifespan for the padlock. Utility Model Content

[0005] In order to reduce the probability of adverse effects of external rain and humid environment on the circuit board inside the lock body, this application provides a waterproof padlock.

[0006] This application provides a waterproof padlock, which adopts the following technical solution:

[0007] A waterproof padlock includes a lock body and a lock beam. The lock body houses a circuit board and a power supply. The lock body has a mortise and a keyhole. The lock beam connects to the lock body via the mortise. The lock body unlocks via the keyhole. The lock body is equipped with a sealing device for sealing the gap between the mortise and the lock beam. The sealing device includes:

[0008] A sealing ring is provided on the lock body and located at the opening of the jack hole;

[0009] A sealing gasket is placed inside the insertion hole;

[0010] A compression spring is disposed within a socket, and the bottom of the compression spring is embedded within a sealing pad.

[0011] A sealing plate, which is horizontally slidably mounted on the lock body;

[0012] A moving mechanism is provided on the lock body and is used to drive the sealing plate to move. The sealing plate blocks the keyhole under the action of the moving mechanism.

[0013] By adopting the above technical solution, a sealing ring is installed at the keyhole opening on the lock body. The sealing ring seals the gap between the mortise and the lock beam, reducing the probability of external water entering the lock body through the gap between the mortise and the lock beam. Then, a sealing pad is placed inside the mortise, and a compression spring is installed. When the lock beam enters the mortise, it compresses the compression spring, which in turn compresses the sealing pad. The deformation of the sealing pad under compression fills the gap between the lock beam and the mortise, thus sealing the gap between the lock beam and the mortise and reducing the probability of external water entering the lock body through the gap between the mortise and the lock beam. The sealing plate, under the action of the moving mechanism, blocks the keyhole, thereby reducing the probability of water entering the lock body from the keyhole and protecting the circuit boards and other components inside the lock body.

[0014] Optionally, the moving mechanism includes:

[0015] A movable spring is mounted on the lock body and connected to a sealing plate, which blocks the keyhole under the action of the movable spring.

[0016] A compression assembly is disposed on the lock body and is used to compress the moving spring.

[0017] By adopting the above technical solution, when the padlock is outdoors and in the locked state, the sealing plate blocks the keyhole under the action of the moving spring, thereby reducing the probability of water entering the lock body through the keyhole. When the keyhole needs to be used for unlocking, the compression component is used to compress the moving spring, so that the sealing plate can be removed from the keyhole, which is convenient and quick.

[0018] Optionally, the compression component includes:

[0019] A compression block, which is horizontally slidably disposed on the lock body and connected to the end of a movable spring;

[0020] An electric push rod is mounted on the lock body and electrically connected to a power source, with its end abutting against a compression block.

[0021] A limiting component is provided on the lock body. The limiting component is used to limit the position of the compression block after the electric push rod pushes the compression block to compress the moving spring.

[0022] By adopting the above technical solution, the electric push rod starts and drives the compression block to move. The movement of the compression block compresses the moving spring, and the moving spring drives the sealing plate to move away from the keyhole. Then, the position of the compression block is limited by the limiting component, so that the keyhole is kept in the open state, making it convenient for the user to insert the key into the keyhole to unlock it.

[0023] Optionally, the limiting member includes:

[0024] A limiting block, which is horizontally slidably mounted on the compression block;

[0025] A limiting spring is provided, and a limiting hole is provided on the lock body. Under the action of the limiting spring, the limiting block is partially inserted into the limiting hole.

[0026] By adopting the above technical solution, when the compression block moves and compresses the moving spring to the target position, the limiting block partially engages with the limiting hole under the action of the limiting spring, thereby limiting the position of the compression block. This ensures that the moving spring and the sealing plate remain fixed after the electric push rod returns to its original position. When it is necessary to move the sealing plate back to its original position, the moving limiting block disengages from the limiting hole, and the sealing plate moves back to its original position under the elastic deformation restoring force of the moving spring and blocks the lock hole.

[0027] Optionally, the end of the limiting block that is inserted into the limiting hole has an arc-shaped first guide surface on the side wall near the electric push rod.

[0028] By adopting the above technical solution, an arc-shaped first guide surface is opened on the side wall near the electric push rod at the end where the limiting block is inserted into the limiting hole. When the limiting block is moved by personnel to compress the limiting spring, after the first guide surface contacts the inner wall of the limiting hole, a component force is generated under the elastic deformation restoring force of the moving spring to drive the limiting block into the limiting hole. Therefore, it is not necessary for the entire limiting block to be moved into the limiting hole by personnel, which reduces the difficulty of operation and improves work efficiency.

[0029] Optionally, a pressure sensor is provided on the lock body, and a controller is provided on the lock body. The controller is electrically connected to both the pressure sensor and the electric push rod.

[0030] By adopting the above technical solution and installing a pressure sensor on the lock body, when the user grips the lock body, the pressure sensor will sense the pressure and transmit the pressure signal to the controller. The controller will then control the electric push rod to move the sealing plate away from the keyhole, making it convenient and quick for the user to insert the key into the keyhole to unlock the lock.

[0031] Optionally, an inclined second guide surface is provided on the inner wall of the insertion hole, and the distance between the bottom end of the second guide surface and the compression spring is smaller than the distance between the top end of the second guide surface and the compression spring.

[0032] By adopting the above technical solution, an inclined second guide surface is formed on the inner wall of the socket. This second guide surface allows for better insertion between the locking beam and the socket, improving the sealing performance between them.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By installing a sealing ring at the keyhole opening on the lock body, the sealing ring seals the gap between the mortise and the lock beam, reducing the probability of external water entering the lock body through the gap between the mortise and the lock beam;

[0035] 2. By placing a sealing pad inside the mortise and installing a compression spring, when the lock beam enters the mortise, the lock beam will compress the compression spring. After the compression spring is compressed, it will compress the sealing pad. The deformation of the sealing pad after being compressed will fill the gap between the lock beam and the mortise, thereby sealing the gap between the lock beam and the mortise and reducing the probability of external water entering the lock body through the gap between the mortise and the lock beam.

[0036] 3. By creating an inclined second guide surface on the inner wall of the socket, the locking beam and the socket can be better connected, thus improving the sealing performance between them. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0041] This application discloses a waterproof padlock.

[0042] Reference Figure 1 and Figure 2The waterproof padlock includes a lock body 11 and a lock beam 12. A circuit board and power supply are fixedly installed inside the lock body 11. A mortise hole 13 is provided at the top of the lock body 11, and a lock hole 14 is provided at the bottom of the lock body 11. The lock beam 12 is connected to the lock body 11 through the mortise hole 13, and the lock body 11 is unlocked through the lock hole 14. A sealing device 2 is provided on the lock body 11 to seal the gap between the mortise hole 13 and the lock beam 12, as well as the lock hole 14.

[0043] Reference Figure 1 and Figure 2 The sealing device 2 includes a sealing ring 21, a sealing pad 22, a compression spring 23, a sealing plate 24, and a moving mechanism 25. The sealing ring 21 is fixedly installed on the top of the lock body 11 and located at the opening of the insertion hole 13. The sealing ring 21 blocks and seals the gap between the lock beam 12 and the opening of the insertion hole 13. An inclined second guide surface 18 is provided on the inner sidewall of the insertion hole 13. The distance between the bottom end of the second guide surface 18 and the lock beam 12 is smaller than the distance between the top end of the second guide surface 18 and the lock beam 12.

[0044] Reference Figure 1 and Figure 2 A sealing pad 22 is placed on the inner bottom wall of the socket 13. A compression spring 23 is also fixedly installed on the inner bottom wall of the socket 13. The bottom of the compression spring 23 is embedded in the sealing pad 22. When the locking beam 12 enters the socket 13, the locking beam 12 compresses the compression spring 23, which in turn compresses the sealing pad 22. The deformation of the sealing pad 22 under compression fills the gap between the locking beam 12 and the socket 13. This seals the gap between the locking beam 12 and the socket 13, reducing the probability of external water entering the lock body 11 through the gap between the socket 13 and the locking beam 12.

[0045] Reference Figure 1 and Figure 2 The sealing plate 24 is horizontally slidably disposed at the bottom of the lock body 11. A moving mechanism 25 is disposed on the lock body 11 and is used to drive the sealing plate 24 to move. Under the action of the moving mechanism 25, the sealing plate 24 blocks the keyhole 14. The moving mechanism 25 includes a moving spring 26 and a compression assembly 27.

[0046] Reference Figure 1 and Figure 2 The lock body 11 has a horizontal sliding groove 28 inside. A sealing plate 24 is slidably mounted on the sliding groove 28. A moving spring 26 is fixedly mounted on the bottom wall of the sliding groove 28 and connected to the sealing plate 24. Under the action of the moving spring 26, the sealing plate 24 partially protrudes from the sliding groove 28 to block the opening of the lock hole 14. A compression assembly 27 is provided on the lock body 11 and is used to compress the moving spring 26.

[0047] Reference Figure 1 and Figure 2The compression assembly 27 includes a compression block 31, an electric push rod 32, and a limiting member 33. The compression block 31 is horizontally slidably installed inside the lock body 11 and connected to the end of the moving spring 26. The electric push rod 32 is fixedly installed inside the lock body 11 and connected to a power source. The piston rod end of the electric push rod 32 abuts against the outer wall of the compression block 31 on the side away from the moving spring 26. A pressure sensing plate 15 is fixedly installed on the outer wall of the lock body 11. A controller 16 is installed inside the lock body 11. The controller 16 is electrically connected to both the pressure sensing plate 15 and the electric push rod 32.

[0048] Reference Figure 1 and Figure 2 When a user grips the lock body 11, the pressure sensor 15 senses the pressure and transmits the pressure signal to the controller 16. The controller 16 then controls the electric push rod 32 to move. The movement of the electric push rod 32 causes the compression block 31 to move, which in turn compresses the moving spring 26. The moving spring 26 causes the sealing plate 24 to move away from the lock hole 14, making it easier for the user to insert the key into the lock hole 14 for unlocking, which is convenient and quick.

[0049] Reference Figure 1 and Figure 2 A limiting member 33 is provided on the lock body 11. The limiting member 33 is used to limit the position of the compression block 31 after the electric push rod 32 pushes the compression block 31 to compress the moving spring 26. The limiting member 33 includes a limiting block 34 and a limiting spring 35. A limiting hole 36 is provided on the outer wall of the lock body 11. A horizontal moving groove 37 is provided on the side wall of the compression block 31 near the limiting hole 36. The limiting block 34 is slidably mounted on the moving groove 37. The limiting spring 35 is fixedly mounted on the inner bottom wall of the moving groove 37 and connected to the limiting block 34. When the compression block 31 moves to the point where the moving groove 37 is aligned with the limiting hole 36, the limiting block 34 partially protrudes from the moving groove 37 under the action of the limiting spring 35 and engages with the limiting hole 36. An arc-shaped first guide surface 17 is provided on the side wall near the electric push rod 32 at the end of the limiting block 34 that engages with the limiting hole 36.

[0050] Reference Figure 1 and Figure 2 When the compression block 31 moves and compresses the moving spring 26 to the target position, the limiting block 34, under the action of the limiting spring 35, partially engages with the limiting hole 36, thereby limiting the position of the compression block 31. This ensures that after the electric push rod 32 returns to its original position, the positions of the moving spring 26 and the sealing plate 24 remain fixed. When it is necessary to move the sealing plate 24 back to its original position, the moving limiting block 34 disengages from the limiting hole 36, and the sealing plate 24 moves back to its original position under the elastic deformation restoring force of the moving spring 26, thus blocking the lock hole 14.

[0051] The working principle of this application embodiment is as follows:

[0052] A sealing ring 21 is installed at the opening of the lock hole 14 on the lock body 11. The sealing ring 21 seals the gap between the mortise hole 13 and the lock beam 12, reducing the probability that external water will enter the lock body 11 through the gap between the mortise hole 13 and the lock beam 12.

[0053] A sealing pad 22 is placed inside the socket 13, and a compression spring 23 is installed. When the locking beam 12 enters the socket 13, the locking beam 12 will compress the compression spring 23. After the compression spring 23 is compressed, it will compress the sealing pad 22. The deformation of the sealing pad 22 after being compressed will fill the gap between the locking beam 12 and the socket 13, thereby sealing the gap between the locking beam 12 and the socket 13 and reducing the probability of external water entering the lock body 11 through the gap between the socket 13 and the locking beam 12.

[0054] The sealing plate 24 blocks the keyhole 14 under the action of the moving spring 26, thereby reducing the probability of water entering the lock body 11 from the keyhole 14 and protecting the circuit board and other components inside the lock body 11.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
