Description
Technical Field
[0001] This utility model relates to the field of locks, and in particular to a reversible smart shop lock. Background Technology
[0002] Shop door locks are a type of door lock that differs from household door locks. Due to various design requirements, shop door locks are all conventional mechanical locks. When in use, a mechanical key is inserted into the lock cylinder and drives the lock cylinder to turn, which in turn drives the bolt to unlock or lock. This means that shop owners need to use a mechanical key to unlock the door when opening and closing, which is not only very cumbersome, but also makes it impossible to monitor the opening and closing of the door lock in real time, which has significant drawbacks.
[0003] In existing technologies, mechanical shop door locks are being upgraded with intelligent features, combining the advantages of both mechanical and smart locks. For example, Chinese Utility Model Patent 2025212145857 discloses a door lock that can be installed without modifying the holes on the door. However, this type of lock uses rotating slots, threading slots, and pull slots on the base. Since the threading slots are eccentrically positioned on the base, while this solves the problem of needing to modify the holes, it also leads to the need to distinguish between upright and reverse installation. Not only do manufacturers need to keep inventory of both upright and reverse-installed locks, but users also need to carefully distinguish them when purchasing, which still has certain drawbacks. Therefore, there is an urgent need for an upright and reverse-installed smart shop lock to solve the above problems. Utility Model Content

[0037] Reference Figures 1 to 4 A reversible smart shop lock includes a front lock body 100, a rear lock body 200, a shop lock cylinder 300, and a linkage rod 400, with holes opened on the door body;
[0038] The front lock body 100 is installed outside the door and has a first control plate 510 on it, while the rear lock body 200 is installed inside the door and has a second control plate 520 on it.
[0039] The shop lock cylinder 300 includes a base 310 and a dial 320. The base 310 is installed in the hole and has a rotating through groove 311 and a pull through groove 312. The dial 320 is rotatably installed in the rotating through groove 311 and connected to the dial 320. The front lock body 100 and the rear lock body 200 are connected by a pull bolt 600 passing through the pull through groove 312.
[0040] One end of the linkage rod 400 is connected to the front lock body 100, and the other end is passed through the dial 320 and connected to the rear lock body 200. A wire through groove 410 is provided on the linkage rod 400.
[0041] The connecting wire between the first control board 510 and the second control board 520 is threaded through the wire through groove 410.
[0042] In this utility model, the base 310 of the shop lock cylinder 300 is adapted to the hole on the door. During installation, the dial 320 is installed in the base 310, and then the entire shop lock cylinder 300 is placed into the hole on the door. The lock body with the latch 330 is then placed into the slot of the door and fixed, so that the dial 320 is connected to the latch 330. The assembled front lock body 100 is then placed outside the door and opposite the hole, with the other end of the linkage rod 400 passing through the dial 320 and extending into the door. The assembled rear lock body 200 is then placed inside the door and opposite the hole, with the other end of the linkage rod 400 passing through the rear lock body 200. In some embodiments, the rear lock body 200... The lock is equipped with an unlocking knob 220 that connects to the other end of the linkage rod 400, which can be used to unlock the shop lock. Then, the connecting wire of the front lock body 100 is passed through the wire through groove 410 on the linkage rod 400 and connected to the connecting wire on the rear lock body 200 through a quick connector. Finally, the front lock body 100 and the rear lock body 200 are connected together by using tie bolts 600 through the tie through groove 312, and both the front lock body 100 and the rear lock body 200 are fixed to the door. In a further embodiment, the cross-sectional outline of the linkage rod 400 is set to a rectangle. Of course, the cross-sectional outline of the linkage rod 400 can also be set to a triangle or other non-circular shape.
[0043] Reference Figures 1-4 In some embodiments, the front lock body 100 includes a front housing 110 and a clutch seat 120, a clutch pin 130, an authentication component 140, an electronically controlled drive component 150, and a mechanical drive component 160 disposed within the front housing 110.
[0044] The clutch seat 120 is connected to one end of the linkage rod 400 and has several clutch grooves 121 arranged around it in the circumferential direction;
[0045] The clutch pin 130 is movably disposed within the front housing 110;
[0046] The authentication component 140 is electrically connected to the first control board 510 and is used to authenticate the user's identity;
[0047] The electric drive assembly 150 is electrically connected to the first control board 510 and to the clutch pin 130, and the mechanical drive assembly 160 is connected to the clutch pin 130.
[0048] When the clutch pin 130 is separated from the clutch groove 121, it can cause the front housing 110 to be free from the linkage rod 400, so that the front housing 110 can rotate freely; or, when the authentication component 140 verifies the identity, the first control board 510 controls the electronic drive component 150 to drive the clutch pin 130 to be inserted into the clutch groove 121, so that the front housing 110 is linked with the linkage rod 400, so that the front housing 110 can be unlocked by rotating the front housing 110; or, the mechanical drive component 160 can drive the clutch pin 130 to be inserted into the clutch groove 121, so that the front housing 110 is linked with the linkage rod 400, so that the front housing 110 can be unlocked by rotating the front housing 110.
[0049] Specifically, the cooperation of the electronically controlled drive component 150, the identity recognition component 140, and the first control board 510 enables electronic unlocking of the shop lock. Specifically, before unlocking, the user first authenticates their identity through the identity recognition component 140. Preferably, the identity recognition component 140 includes at least one of a digital password module 810, an NFC module, a fingerprint recognition module 820, a finger vein recognition module, an iris recognition module, and a face recognition module, preferably a fingerprint recognition module. When fingerprint recognition is successful, the first control board 510 sends an unlocking command to the electronically controlled drive component 150. After receiving the unlocking command, the electronically controlled drive component 150 drives the clutch pin 130 to engage with the clutch. Within the slot 121, since the linkage rod 400 and the clutch seat 120 are connected in synchronous motion, the front housing 110 and the linkage rod 400 are linked at this time. When the front housing 110 is rotated, the entire front lock body 100 and the linkage rod 400 will rotate together, ultimately unlocking the lock cylinder. Furthermore, the mechanical drive assembly 160 can realize mechanical unlocking of the ball lock. Specifically, the user can use a mechanical key that is compatible with the mechanical drive assembly 160 to operate the mechanical drive assembly 160, which will also drive the clutch pin 130 to be inserted into the clutch slot 121. When the housing 110 is rotated, the entire front lock body 100 and the linkage rod 400 will rotate together, ultimately unlocking the lock cylinder.
[0050] Reference Figures 1-4 In some embodiments, the electronically controlled drive assembly 150 includes a motor 151, a rotating shaft 152, a first movable seat 153, and a coil spring;
[0051] One end of the rotating shaft 152 is connected to the output shaft of the motor 151, and the other end passes through the first movable seat 153. A positioning post 154 is provided on the rotating shaft 152.
[0052] The first movable seat 153 abuts against the clutch pin 130;
[0053] The helical spring is mounted on the first movable seat 153 and sleeved on the rotating shaft 152, and the positioning pin 154 extends into the helical channel of the helical spring.
[0054] Specifically, when the identity recognition component 140 verifies and passes the identity verification, the first control board 510 will send an unlocking command to the motor 151. The motor 151 drives the rotating shaft 152 to rotate, and the positioning pin 154 on the rotating shaft 152 rotates synchronously with it. Since the first movable seat 153 moves linearly inside the front housing 110, and the coil spring moves linearly synchronously with the first movable seat 153, the rotational motion of the rotating shaft 152 is converted into the linear motion of the coil spring and the first movable seat 153, thereby pushing the clutch pin 130 to be inserted into the clutch groove 121 to complete the gear engagement.
[0055] Reference Figures 1-4 In some embodiments, the mechanical drive assembly 160 includes a mechanical lock cylinder 161 and a second movable seat 162. The second movable seat 162 is connected to the output end of the mechanical lock cylinder 161 and is connected to the front housing 110 through a guide structure 700. The second movable seat 162 abuts against the first movable seat 153. Specifically, when the user inserts the mechanical key into the mechanical lock cylinder 161 and rotates it, the second movable seat 162 will rotate. Since the second movable seat 162 is connected to the front housing 110 through the guide structure 700, the rotational motion of the output end of the mechanical lock cylinder 161 will be converted into the linear motion of the second movable seat 162. Then, the movement of the first movable seat 153 will push the clutch pin 130 to move, and finally push the clutch pin 130 into the clutch groove 121 to complete the engagement.
[0056] Reference Figure 2 In some embodiments, the guide structure 700 includes a guide block 710 disposed on the second movable seat 162 and a guide groove 720 disposed on the front housing 110, with the guide block 710 extending into the guide groove 720.
[0057] Reference Figures 1-4 In some embodiments, the rear lock body 200 includes a rear housing 210, an unlocking knob 220, and a battery 230. The unlocking knob 220 is rotatably mounted on the rear housing 210 and is connected to the other end of the linkage rod 400. The battery 230 is mounted on the rear housing 210 and is electrically connected to the second control board 520. The unlocking knob 220 can be used inside the door to manually lock and unlock, and the battery 230 can also be replaced inside the door.
[0058] Reference Figures 3-4In some embodiments, the rotation angle of the unlocking knob 220 is set to 0-90°. The unlocking knob 220 is connected to the rear housing 210 through an angle holding assembly 800 to keep the unlocking knob 220 in the 0° or 90° position. Preferably, the angle holding assembly 800 includes a torsion spring 810, one end of which is rotatably connected to the rear housing 210 and the other end of which is rotatably connected to the unlocking knob 220. Specifically, when the user unlocks the door from the inside using the unlocking knob 220, it will drive the linkage rod 400 to rotate and drive the dial 320 to drive the bolt 330 to unlock or lock. At the same time, it will also drive the torsion spring 810 to rotate. The deformation and displacement of the torsion spring 810 will apply a force to keep the unlocking knob 220 in the 0° or 90° position, thereby allowing the shop lock to remain in the unlocked or locked state, meeting the relevant standards for shop locks.
[0059] Reference Figure 2 In some embodiments, the clutch groove 121 is set to 4 and evenly distributed around the clutch seat 120. When installing the shop lock, the bolt 330 needs to be operated to the locked state, that is, the bolt 330 is extended. At this time, the dial 320 is at the 0° position, which can be rotated to the left or the right, depending on whether the door is left-opening or right-opening. After the shop lock is fully installed, the front lock body 100 is operated to the linkage state through the electric control drive component 150 or the mechanical drive component 160. At this time, the front housing 110 is rotated in the opposite direction to drive the dial to the 90° position, realizing reverse lifting and locking, which also meets the relevant standards of shop locks.
[0060] Reference Figure 2 In some embodiments, the pull-through groove 312 is configured as two and is arranged on both sides of the rotation groove 311.
[0061] The advantages of this utility model are: the above structure not only enables intelligent mechanical shop locks, but also allows for wire threading between the front and rear lock bodies without altering the holes in the door, reducing the complexity and labor costs of door lock installation. Furthermore, it eliminates the need to distinguish between forward and reverse installation, reducing manufacturer inventory and improving installation convenience, thus meeting user needs.
[0062] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
