Technical Field

[0001] This utility model relates to the technical field of smart locks, and more specifically, to a Bluetooth padlock with a sealing locking mechanism. Background Technology

[0002] Padlocks come in two types: split padlocks and flip-out padlocks. In flip-out padlocks, one end remains inside the lock body during use, while the other end is locked by pressing the lock beam. To facilitate unlocking, the padlock is integrated with Bluetooth technology, allowing remote unlocking via Bluetooth connection to a mobile phone.

[0003] However, existing Bluetooth padlocks have a keyhole at the bottom. By inserting an emergency key into the keyhole, the padlock can be opened even when a mobile phone or other connected device is not present. The emergency key is inserted into the keyhole and then contacts the electrical contacts of the control module inside the padlock. However, existing Bluetooth padlocks do not have a sealing structure at the bottom of the keyhole. This results in deficiencies in waterproofing, dustproofing, and the sealing of the locking mechanism. Water and dust can easily enter the lock body through the keyhole, causing the electrical contacts of the control module to be contaminated by water or dust, leading to lock malfunctions and affecting the service life.

[0004] Therefore, a Bluetooth padlock with a sealing locking mechanism is proposed to address the above problems. Utility Model Content

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.

[0023] Example 1

[0024] As attached Figures 1 to 5 The Bluetooth padlock shown includes a lock body 1, a sealing baffle 3 at the bottom of the lock body 1, a fixed base 5 at each of the four corners of the top of the sealing baffle 3, two connecting ears 6 symmetrically arranged on each of the four fixed bases 5, two clamping rings 7 rotatably connected between the two connecting ears 6, a fixed plate 8 fixedly arranged on the outer wall of each of the two clamping rings 7, a compression spring 9 fixedly connected between the bottom wall of each of the two fixed plates 8 and the fixed base 5, a limiting post 10 fixedly arranged at each of the four corners of the side wall of the lock body 1, a retaining ring 12 fixedly arranged at one end of each of the four limiting posts 10, a rubber sheet 11 connected to the surface of each retaining ring 12 near the surface of the lock body 1, and the limiting posts 10 clamping between the two clamping rings 7, and two arc-shaped actuating blocks 4 symmetrically arranged on the bottom wall of the sealing baffle 3, with rough textures on the back of each of the two arc-shaped actuating blocks 4 to increase the friction between the hand and the arc-shaped actuating blocks 4.

[0025] Specifically: When it is necessary to limit and fix the sealing baffle 3 on the bottom wall of the lock body 1 to close the lock hole 2 on the bottom wall of the lock body 1, the two arc-shaped toggle blocks 4 can be pinched with the thumb and forefinger first, and then the sealing baffle 3 can be pushed upward so that the clamping ring 7 on the sealing baffle 3 contacts the limiting post 10 set on the lock body 1. Then continue to push the sealing baffle 3. At this time, the upper ends of the two clamping rings 7 slide open along the arc-shaped outer wall of the limiting post 10. At the same time, the two compression springs 9 are compressed and deformed until the two clamping rings 7 are completely attached to the outer wall of the limiting post 10. At this time, the two compression springs 9 will push the two clamping rings 7 to reset through the fixing piece 8, thus completing the clamping and fixing of the limiting post 10.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0028] In a preferred embodiment, a base plate 21 is bolted to the bottom wall of the lock body 1. A lock hole 2 is provided on the base plate 21, and an emergency spare key 23 is inserted into the lock hole 2. A Bluetooth 22 is installed on the lock body 1. The Bluetooth 22 is existing technology, such as the JBLC230TWS manufactured by Harman (China) Investment Co., Ltd., and will not be described in detail here. A signal controller 13 is provided inside the lock body 1 and at the top of the lock hole 2. The signal controller 13 is existing technology, such as the MC56F84789VLL manufactured by NXP Semiconductors, and will not be described in detail here. An electric push rod 14 is provided inside the lock body 1 and connected to the signal controller 13 via a wire. A wedge block 15 is connected to the output end of the electric push rod 14. A detachable buckle 17 is movably inserted into the top of the lock body 1. One side wall of the detachable buckle 17 has a latching hole 16 that engages with the wedge block 15. An installation cavity 18 is provided inside the lock body 1. The other end of the detachable buckle 17... The lock body 1 is rotatably connected to the mounting cavity 18. A locking spring 19 is fixedly installed on the bottom wall of the mounting cavity 18. A baffle 20 is connected to the bottom of one end of the shackle 17 located in the mounting cavity 18. The top of the locking spring 19 is fixedly connected to the bottom wall of the baffle 20. When unlocking is required, the emergency spare key 23 can be inserted into the lock body 1. The power supply contact of the emergency spare key 23 contacts the signal controller 13. The signal controller 13 controls the electric push rod 14 to start. The electric push rod 14 drives the wedge block 15 to retract, so that the wedge block 15 moves away from the latching hole 16 on the shackle 17. At this time, the locking spring 19 presses the baffle 20, causing the baffle 20 and the shackle 17 to move upward, so that one end of the shackle 17 is disengaged from the lock body 1, completing the unlocking process. When the emergency spare key 23 is not used, the signal controller 13 is activated by using a mobile terminal with Bluetooth function and Bluetooth 22 non-contact sensing. The signal controller 13 controls the electric push rod 14 to start, realizing the unlocking process.

[0029] The working process of this utility model is as follows: First, when it is necessary to limit and fix the sealing baffle 3 on the bottom wall of the lock body 1 to close the lock hole 2 on the bottom wall of the lock body 1, the two arc-shaped actuating blocks 4 can be pinched with the thumb and forefinger, and then the sealing baffle 3 can be pushed upward so that the clamping ring 7 on the sealing baffle 3 contacts the limiting post 10 set on the lock body 1. Then, the sealing baffle 3 is pushed further. At this time, the upper ends of the two clamping rings 7 slide open along the arc-shaped outer wall of the limiting post 10. At the same time, the two compression springs 9 are compressed and deformed until the two clamping rings 7 are completely attached to the outer wall of the limiting post 10. At this time, the two compression springs 9 will push the two clamping rings 7 to reset through the fixing piece 8, thus completing the clamping and fixing of the limiting post 10, thereby achieving the limiting and fixing of the sealing baffle 3. Through the design of the sealing baffle 3, the waterproof and dustproof performance of the padlock is effectively improved, and the service life of the padlock is extended. Meanwhile, the quick-disassembly structure allows for rapid disassembly and installation of the sealing baffle 3, facilitating the opening of the padlock via the signal controller 13 and subsequent maintenance of the padlock, thus improving the practicality of the device. The above describes the working principle of this Bluetooth padlock with a sealing mechanism.
