Description
Technical Field
[0001] This utility model relates to the field of padlock technology, and more specifically, to an outward-folding NFC padlock. Background Technology
[0002] Padlocks are the oldest and largest family of locks. Currently, there are two types of padlocks: split padlocks and flip-top padlocks. In flip-top padlocks, one end remains inside the lock body, while the other end is locked by pressing the shackle. The lock body of the padlock has a ring-shaped or "I"-shaped metal bar, known as the "shackle," which allows the padlock to be directly engaged with the lock body to form a closed lock.
[0003] A search revealed that publication number CN217812911U discloses a smart NFC passive padlock, including a lock body and an NFC passive locking device. The NFC passive locking device is mounted on the lock body and includes an intelligent control structure and a locking structure. A sliding structure is provided on the lock body. The intelligent control structure includes an NFC sensing unit, an electronic key, a drive module, and a control module. It has the following advantages: The intelligent control structure and locking structure, through their cooperation, allow the passive padlock to be unlocked not only using an electronic key but also via NFC sensing, which is convenient and fast. The sliding structure, through the cooperation of its components, can cover the keyhole when the padlock is not in use, preventing dust from entering the keyhole and causing the electronic key to malfunction when inserted into the lock body. The inventors discovered the following problems with the existing technology during the development of this utility model:
[0004] However, when the sliding structure in the device slides the baffle to close the lock hole, the lack of a limiting structure to limit and fix the baffle at the lock hole position due to the movable connection of the slider makes it easy for the baffle to slide when the padlock is hit. This results in the baffle not being able to stably block the locking position, and dust may still enter the lock hole, causing the electronic key to malfunction when inserted into the lock body.
[0005] Therefore, an outward-folding NFC padlock is proposed to address the above issues. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an outward-folding NFC padlock to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an outward-opening NFC padlock, comprising a lock body, an electronic key, and an NFC sensing unit. The NFC sensing unit is installed on the lock body, and a keyhole is provided at the bottom of the lock body. A first sliding groove is provided inside the lock body and below the keyhole. A baffle is slidably connected in the first sliding groove. A fixing hole is provided at one end of the baffle. A first mounting cavity is provided inside the lock body. A connecting post is provided in the first mounting cavity. A fixing post that is inserted and connected to the fixing hole is fixedly provided at the bottom of the connecting post. A first spring is sleeved on the outside of the connecting post and inside the first mounting cavity. A second mounting cavity is provided inside the lock body and above the first mounting cavity. The top end of the connecting post extends into the second mounting cavity, and a lifting post is fixed to the top end of the connecting post. An upward-moving component for pushing the lifting post is provided inside the lock body.
[0008] Preferably, the upward moving component includes a socket, a rod, a third mounting cavity, and a second spring. The lock body has a third mounting cavity, in which the rod is inserted. The lifting column has a socket that is inserted and connected to one end of the rod. A stop block is fixedly connected to the outside of the rod, and a second spring is sleeved on the outside of the rod.
[0009] Preferably, two connecting blocks are symmetrically arranged on the bottom wall of the baffle, and one end of the two connecting blocks is connected to a toggle block. A second sliding groove is provided at the bottom of the lock body, and the toggle block is slidably connected in the second sliding groove.
[0010] Preferably, one end of the electronic key is inserted into the keyhole, and the electronic key is equipped with a sensor light.
[0011] Preferably, a control module is installed inside the lock body and at the top of the lock hole. A shackle is provided at the top of the lock body, and a snap-fit hole is opened at the top of the lock body. One end of the shackle is inserted into the snap-fit hole, and a wedge-shaped groove is opened at one end of the shackle.
[0012] Preferably, a drive module is installed in the lock body, a connector is connected to the output end of the drive module, an elastic block is connected to one end of the connector, a wedge block is fixedly installed at one end of the elastic block, the wedge block is inserted into the wedge groove, and the control module and the drive module are connected by a wire.
[0013] Preferably, a fourth mounting cavity is provided at the top of the lock body and at a position symmetrical to the latching hole. A third spring is fixedly installed in the fourth mounting cavity, and a baffle is movably installed at the top of the third spring. The end of the shackle away from the latching hole is connected to the baffle.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. Compared with the existing technology, this outward-folding NFC padlock uses a first spring to compress the fixing post, causing the fixing post to move downward. Then, the downward-moving fixing post engages with the fixing hole opened on the surface of the baffle, thereby limiting and fixing the baffle that moves and closes at the bottom of the lock hole. This allows the baffle to stably block the lock hole, preventing dust from entering the lock hole and causing the electronic key to malfunction when inserted into the lock hole.
[0016] 2. Compared with the existing technology, this outward-folding NFC padlock allows one end of the insert rod to be inserted into the hole opened on the lifting column when the insert rod is fully inserted into the hole. When the insert rod is fully inserted into the hole, the position of the lifting column will gradually move upward, which in turn drives the fixed column to move upward through the connecting column, making it easier to remove the cover of the bottom of the lock hole afterward.

[0023] 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.
[0024] Example 1
[0025] As attached Figures 1 to 5 The illustrated outward-opening NFC padlock includes a lock body 1, an NFC sensing unit 33 mounted on the lock body 1, a lock hole 2 at the bottom of the lock body 1, a first sliding groove 3 inside the lock body 1 and below the lock hole 2, a baffle 4 slidably connected in the first sliding groove 3, a fixing hole 5 at one end of the baffle 4, a first mounting cavity 7 inside the lock body 1, a connecting post 8 inside the first mounting cavity 7, a fixing post 6 fixedly mounted at the bottom of the connecting post 8 and inserted into the fixing hole 5, a first spring 9 sleeved outside the connecting post 8 and inside the first mounting cavity 7, a second mounting cavity 10 inside the lock body 1 and above the first mounting cavity 7, the top end of the connecting post 8 extending into the second mounting cavity 10, and a lifting post 11 fixed at the top end of the connecting post 8, and an upward moving component inside the lock body 1 for pushing the lifting post 11.
[0026] In use, the device can first slide the baffle 4 to the bottom of the lock hole 2 to block and close the bottom of the lock hole 2. Then, the first spring 9 presses the fixing post 6 to move down. The lowered fixing post 6 then engages with the fixing hole 5 on the surface of the baffle 4, thereby limiting and fixing the baffle 4 that moves and closes to block the bottom of the lock hole 2. This allows the baffle 4 to block the lock hole 2 relatively stably, preventing dust from entering the lock hole 2 and causing the electronic key 20 to malfunction when inserted into the lock hole 2.
[0027] Example 2
[0028] 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:
[0029] In a preferred embodiment, the upward-moving component includes a socket 12, a rod 13, a third mounting cavity 14, and a second spring 15. The third mounting cavity 14 is located inside the lock body 1, and the rod 13 is inserted into the third mounting cavity 14. A socket 12 is provided on the lifting column 11 to connect with one end of the rod 13. A stop 16 is fixedly connected to the outside of the rod 13, and a second spring 15 is sleeved on the outside of the rod 13. When the sliding baffle 4 closes or releases the bottom of the lock hole 2, the second spring 15 is inserted into the bottom of the lock hole 2. When the barrier is closed, the insertion rod 13 can be pressed directly. At this time, the end of the insertion rod 13 with the inclined surface will gradually insert into the insertion hole 12 set on the lifting column 11. As the insertion rod 13 is fully inserted into the insertion hole 12, the position of the lifting column 11 will gradually move upward. Then, the lifting column 11 drives the fixing column 6 to move upward through the connecting column 8, thereby releasing the insertion connection between the fixing column 6 and the fixing hole 5 opened on the baffle 4, thus facilitating the sliding of the baffle 4 and releasing the obstruction of the bottom end of the lock hole 2 by the baffle 4.
[0030] In a preferred embodiment, two connecting blocks 18 are symmetrically arranged on the bottom wall of the baffle 4. Then, a toggle block 17 is connected to one end of the two connecting blocks 18. A second sliding groove 19 is provided at the bottom of the lock body 1. Finally, the toggle block 17 is slidably connected in the second sliding groove 19. When the baffle 4 needs to be slidable, the toggle block 17 can be pressed and slid directly. Then, the sliding toggle block 17 drives the baffle 4 to move through the two connecting blocks 18, so that the bottom of the lock hole 2 can be closed by the sliding baffle 4.
[0031] In a preferred embodiment, one end of the electronic key 20 is inserted into the keyhole 2, and a sensor light 21 is installed on the electronic key 20. A control module 22 is installed inside the lock body 1 at the top of the keyhole 2. A shackle 32 is then provided at the top of the lock body 1, and a latching hole 23 is opened at the top of the lock body 1. One end of the shackle 32 is inserted into the latching hole 23, and a wedge-shaped groove 28 is opened at one end of the shackle 32. A drive module 24 is installed inside the lock body 1, and a connecting wire is connected to the output end of the drive module 24. The connector 25 is connected to an elastic block 26 at one end, and a wedge block 27 is fixedly installed at one end of the elastic block 26. The wedge block 27 is inserted into the wedge groove 28. Meanwhile, the control module 22 and the drive module 24 are connected by wires. A fourth mounting cavity 29 is opened at the top of the lock body 1 and at a position symmetrical to the buckle hole 23. A third spring 30 is fixedly installed in the fourth mounting cavity 29. A baffle 31 is movably installed at the top of the third spring 30. The end of the shackle 32 away from the buckle hole 23 is connected to the baffle 31.
[0032] When unlocking is required, the electronic key 20 can be inserted into the lock body 1. The power supply contact of the electronic key 20 contacts the control module 22, which controls the drive module 24 to start. The drive module 24 drives the wedge block 27 to retract, so that the wedge block 27 moves away from the wedge groove 28 on the shackle 32. At this time, the third spring 30 presses the baffle 31, which drives the baffle 31 and the shackle 32 to move upward, so that one end of the shackle 32 disengages from the latching hole 23, completing the unlocking process. When the electronic key 20 is not used, the control module 22 is activated by non-contact sensing of the NFC sensing unit 33 using a mobile terminal with NFC function. The control module 22 controls the drive module 24 to start, realizing the unlocking process.
[0033] The working process of this utility model is as follows: First, when unlocking is not required, press the insertion rod 13 directly. At this time, the end of the insertion rod 13 with the inclined surface will gradually insert into the insertion hole 12 set on the lifting column 11. As the insertion rod 13 is fully inserted into the insertion hole 12, the position of the lifting column 11 will gradually move upward. Then, the lifting column 11 drives the fixing column 6 to move upward through the connecting column 8, thereby releasing the insertion connection between the fixing column 6 and the fixing hole 5 opened on the baffle 4. At this time, the other hand presses and slides the toggle block 17. Then, the sliding toggle block 17 drives the baffle 4 to move through the two connecting blocks 18, and thus the lock can be opened. The sliding baffle 4 closes the bottom of the lock hole 2, and then the insertion rod 13 is released. At this time, the second spring 15 presses the stop block 16, and the insertion rod 13 is moved away from the lifting column 11 through the stop block 16. After the upward force of the lifting column 11 is released, the first spring 9 will press the fixed column 6 to move down. Then, the fixed column 6 moves down and is inserted into the fixed hole 5 opened on the surface of the baffle 4, thereby limiting and fixing the baffle 4 that moves and closes at the bottom of the lock hole 2. This allows the baffle 4 to stably block the lock hole 2, preventing dust from entering the lock hole 2 and causing the electronic key 20 to malfunction when inserted into the lock hole 2.
[0034] When unlocking is required, press the insertion rod 13. One end of the insertion rod 13 is inserted into the insertion hole 12 on the lifting column 11. At this time, the fixing column 6 moves upward, releasing the limiting fixation of the baffle 4. Then slide the toggle block 17 and the baffle 4 to release the baffle 4 from blocking the bottom of the lock hole 2. Then the electronic key 20 can be inserted into the lock hole 2 to unlock. The above is the working principle of this outward-folding NFC padlock.
