Description
Technical Field
[0001] This utility model belongs to the field of cabinet technology, and more specifically, it relates to a door lock structure and an automatic vending machine cabinet. Background Technology
[0002] Currently, vending machine door locks on the market consist of an electromagnetic lock body and a magnetic locking plate. The electromagnetic lock body is installed inside the lightbox on top of the vending machine and remains stationary. The locking plate is installed on top of the door. When the electromagnetic lock body and the locking plate attract each other, the door is closed. When there is no attraction between the electromagnetic lock body and the locking plate, the door can be opened, and the locking plate and its magnet rotate with the door. Because the lock body is large and requires the magnetic locking plate to be installed directly opposite it for it to work, the lock can only be installed on top of the vending machine. However, vending machines are tall, and locking only the top part creates a gap when the door is pulled from the bottom, allowing for theft of goods, a persistent problem in the vending machine industry. Furthermore, the door cannot be opened when the electromagnetic lock is broken or during a power outage. Utility Model Content
[0003] The purpose of this utility model embodiment is to provide a door lock structure and an automatic vending machine cabinet to solve the technical problems existing in the prior art, such as the electromagnetic lock body being too large, only being able to be installed on the top, and being unable to open the door when the power is off.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a door lock structure, comprising:
[0005] Lock housing structure, used for installation on the door;
[0006] The first lock body assembly includes an electric actuator fixed to the lock housing structure, a connecting rod driven by the electric actuator, and a limiting structure driven to rotate by the connecting rod, the limiting structure being used to engage and lock with the cabinet body.

[0013] Optionally, the door lock structure further includes a support assembly for supporting the limiting structure. The support assembly includes a sleeve structure disposed on the outer periphery of the connecting rod and a limiting pin. The sleeve structure is fixed to the lock housing structure. The limiting pins are multiple and circumferentially disposed on the sleeve structure. The limiting pins pass through the sleeve structure and abut against the surface of the connecting rod.
[0014] Optionally, the electric actuator, the connecting rod, and the transmission assembly are all disposed inside the lock housing structure, while the limiting portion is disposed outside the lock housing structure.
[0015] Optionally, a groove is provided at one end of the connecting rod, the extension direction of the groove is different from the movement direction of the connecting rod, and the push-pull member extends into the groove and can slide along the groove.

[0019] This utility model also proposes an automatic vending machine cabinet, including a door, a cabinet, and the aforementioned door lock structure. The door lock structure is fixed to the door and is used to lock the door to the cabinet.
[0020] The beneficial effects of the door lock structure and vending machine cabinet provided by this utility model are as follows: Compared with the prior art, the door lock structure of this utility model includes a lock shell structure, a first lock body assembly, and a second lock body assembly. The first lock body assembly includes an electric actuator, a connecting rod, and a limiting structure. When the electric actuator is powered, it can drive the limiting structure to move through the connecting rod, realizing the electronic unlocking or unlocking of the door lock structure. The second lock body assembly includes a mechanical lock cylinder and a push-pull component. In the event of a power outage or when the first lock body assembly fails, the door lock structure can still be unlocked by driving the push-pull component and the connecting rod through the mechanical lock.

[0036] Currently, vending machine door locks on the market consist of an electromagnetic lock body and a magnetic locking plate. The electromagnetic lock body is installed inside the lightbox on top of the vending machine and remains stationary. The locking plate is installed on top of the door. When the electromagnetic lock body and the locking plate attract each other, the door is closed. When there is no attraction between the electromagnetic lock body and the locking plate, the door can be opened, and the locking plate and its magnet rotate with the door. Because the lock body is large and requires the magnetic locking plate to be installed directly opposite it for it to work, the lock can only be installed on top of the vending machine. However, vending machines are tall, and locking only the top part creates a gap when the door is pulled from the bottom, allowing for theft of goods, a persistent problem in the vending machine industry. Furthermore, the door cannot be opened when the electromagnetic lock is broken or during a power outage.
[0037] To alleviate or solve the above technical problems, this utility model proposes a door lock structure 100 and an automatic vending machine cabinet. The door lock structure 100 includes a lock shell structure 10, a first lock body assembly 20, and a second lock body assembly 30. The first lock body assembly 20 includes an electric actuator 21, a connecting rod 22, and a limiting structure 24. The electric actuator 21 is electrically driven and drives the limiting structure 24 to rotate for locking or unlocking via the connecting rod 22. The second lock body assembly 30 includes a mechanical lock cylinder 31 and a push-pull member 32. By driving the mechanical lock cylinder 31, the push-pull member 32 and the connecting rod 22 can move, which can also drive the limiting structure 24 to rotate for locking or unlocking. The first lock body assembly 20 is an electronic lock, and the second lock body assembly 30 is a mechanical lock. In the event of a power outage or damage to the first lock body assembly 20, the lock and unlock can be performed using the second lock body assembly 30. Furthermore, the limiting structure 24 and the second lock body assembly 30 are respectively located at both ends of the connecting rod 22, which can make the door lock structure 100 elongated, suitable for installing the door lock structure 100 in the middle of the height direction of the door body 300, thereby improving the anti-theft performance of the vending machine cabinet.
[0038] The door lock structure 100 provided in this embodiment of the present invention will now be described. The door lock structure 100 is installed on the door body 300 and is used to lock the door body 300 and the cabinet body 200.
[0039] Please refer to the following: Figures 1 to 3 The door lock structure 100 includes:
[0040] Lock housing structure 10, for installation on door body 300;
[0041] The first lock body assembly 20 includes an electric actuator 21 fixed to the lock housing structure 10, a connecting rod 22 driven by the electric actuator 21, and a limiting structure 24 driven to rotate by the connecting rod 22. The limiting structure 24 is used to engage and lock with the cabinet 200.
[0042] The second lock body assembly 30 includes a mechanical lock cylinder 31 fixed to the lock housing structure 10 and a push-pull member 32 driven by the mechanical lock cylinder 31, the push-pull member 32 being used to push and pull the connecting rod 22; and
[0043] The controller 51 is communicatively connected to the electric drive 21, and the controller 51 is used to control the electric drive 21;
[0044] The limiting structure 24 and the push-pull component 32 are respectively located at both ends of the connecting rod 22 along its length.
[0045] The lock housing structure 10 is the housing structure part of the door lock structure 100, used to install the first lock body assembly 20, the second lock body assembly 30, the controller 51, etc. The lock housing structure 10 can be directly or indirectly installed on the door body 300, and the lock housing structure 10 and the door body 300 can be detachably or fixedly connected.
[0046] The first lock body assembly 20 is electrically driven and is an electronic lock. The first lock body assembly 20 includes an electric actuator 21, a connecting rod 22, and a limiting structure 24. The electric actuator 21 is electrically driven, and when the electric actuator 21 is working, it drives the connecting rod 22 to move. The connecting rod 22 drives the limiting structure 24 to rotate. The limiting structure 24 rotates until it engages with the cabinet 200, so that the door 300 is locked to the cabinet 200. At this time, the door lock structure 100 is in the locked state. When the limiting structure 24 rotates until it disengages from the cabinet 200, the door 300 can be opened relative to the cabinet 200. At this time, the door lock structure 100 is in the unlocked state.
[0047] The second lock body assembly 30 is driven by the key 40 and is a mechanical lock. The second lock body assembly 30 includes a mechanical lock cylinder 31 and a push-pull member 32. The mechanical lock cylinder 31, the push-pull member 32 and the limiting structure 24 are connected by transmission. After the key 40 is inserted into the mechanical lock cylinder 31, it can drive the mechanical lock cylinder 31 to rotate. The rotation of the mechanical lock cylinder 31 can drive the push-pull member 32 to move. The push-pull member 32 drives the limiting structure 24 to rotate, realizing the locking and unlocking of the door structure 300.
[0048] The controller 51 is communicatively connected to the electric actuator 21, which can be done via wired or wireless means. When the controller 51 receives an opening command, it sends an opening signal. The electric actuator 21 operates according to the opening signal, driving the linkage 22 and the limit structure 24 to perform the unlocking action. When the controller 51 receives a closing command, it sends a closing signal. The electric actuator 21 operates according to the closing signal, driving the linkage 22 and the limit structure 24 to perform the locking action.
[0049] In the event of power failure or damage to the electric actuator 21, the door can be unlocked or locked using the second lock body assembly 30, i.e., using the traditional key 40. Furthermore, in the main structure of the first lock body assembly 20, the connecting rod 22 is connected to the motion output end of the electric actuator 21, occupying a relatively large space. The limiting structure 24 and the second lock body assembly 30 are located at opposite ends of the connecting rod 22, fully utilizing the circumferential space of the connecting rod 22 to minimize the volume of the door lock structure 100. Moreover, the limiting structure 24 locks or unlocks the cabinet 200 by rotation. The door lock structure 100 can be installed in the middle of the door 300 in the height direction. When the door lock structure 100 is locked, even if the door is pulled outward by external force, the gaps between the upper and lower ends of the door 300 and the cabinet 200 will not be large, making it impossible to remove drinks, food, etc., through the gaps.
[0050] The door lock structure 100 in the above embodiment includes a lock shell structure 10, a first lock body assembly 20, and a second lock body assembly 30. The first lock body assembly 20 includes an electric actuator 21, a connecting rod 22, and a limiting structure 24. When the electric actuator 21 is powered, it can drive the limiting structure 24 to move through the connecting rod 22, thereby realizing the electronic unlocking or unlocking of the door lock structure 100. The second lock body assembly 30 includes a mechanical lock cylinder 31 and a push-pull member 32. In the event of a power outage or when the first lock body assembly 20 is damaged, the door lock structure 100 can still be unlocked by the mechanical lock driving the push-pull member 32 and the connecting rod 22. Furthermore, the limiting structure 24 of the first lock body assembly 20 and the second lock body assembly 30 are respectively located at opposite ends of the connecting rod 22, making the door lock structure 100 elongated and smaller in size, allowing it to be installed in the middle of the door body 300. The door lock structure 100 can be locked and unlocked by rotating the limiting structure 24. Thus, when the door lock structure 100 is locked, if the door is pulled forcefully, there will not be excessive gaps on the upper and lower sides of the door body 300, enhancing its anti-theft effect.
[0051] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The electric actuator 21 outputs linear motion, causing the connecting rod 22 to move linearly. The connecting rod 22 and the limiting structure 24 are connected by a transmission assembly 23, which converts the linear motion of the connecting rod 22 into the rotational motion of the limiting structure 24. The electric actuator 21 outputs linear motion, which correspondingly pushes or pulls the connecting rod 22 into linear motion. The connecting rod 22, the transmission assembly 23, and the limiting structure 24 are sequentially connected. When the electric actuator 21 is working, the connecting rod 22 moves linearly, and the limiting structure 24 rotates. The function of the transmission assembly 23 is to convert linear motion into rotational motion.
[0052] By setting the transmission component 23, the linear motion of the connecting rod 22 is converted into the rotational motion of the limiting structure 24, thereby realizing the locking and unlocking of the limiting structure 24 and the cabinet 200.
[0053] In some embodiments, the electric driver 21 includes a linear motor that outputs linear motion. Alternatively, the electric driver 21 includes an electromagnet and a coil; when the coil is energized, it drives the electromagnet to move, thereby outputting linear motion.
[0054] In some embodiments, the direction of motion of the link 22 is parallel to the length direction of the link 22, that is, the link 22 moves in a straight line along its length direction, so that the trajectory of the link 22 is always along its length direction, and the space occupied is relatively small.
[0055] In some embodiments, the rotation center axis of the limiting structure 24 is perpendicular to the length direction of the connecting rod 22. In this way, when the limiting structure 24 rotates, the thickness of the door lock structure 100 remains unchanged, making the door lock structure 100 suitable for installation in the middle of the door body 300 in the height direction. The limiting structure 24 extends into the cabinet body 200 and rotates to lock or unlock within the cabinet body 200.
[0056] In other embodiments, the two ends of the connecting rod 22 are respectively connected to the motion output end of the electric actuator 21 and the limiting structure 24. The motion output end of the electric actuator 21 outputs rotational motion, thus also causing the limiting structure 24 to rotate. In this embodiment, the length direction of the connecting rod 22 coincides with the axis of the motion output end of the electric actuator 21, and the connecting rod 22 acts as a coupling between the electric actuator 21 and the limiting structure 24. In this embodiment, the length direction of the connecting rod 22 can also be perpendicular to the motion output end of the electric actuator 21, causing the limiting structure 24 to rotate.
[0057] Please refer to some embodiments of this utility model. Figure 2 The transmission assembly 23 includes a rack 231 fixed to one end of the connecting rod 22 and a gear 232 fixedly connected to the limiting structure 24. The rack 231 and the gear 232 mesh with each other. The rack 231 is fixed to the end of the connecting rod 22 away from the second lock body assembly 30. When the connecting rod 22 moves, the rack 231 moves synchronously with the connecting rod 22. When the rack 231 moves, it drives the gear 232 to rotate. The rotation of the gear 232 then drives the limiting structure 24 to rotate, thereby realizing the locking and unlocking of the door lock structure 100.
[0058] By designing the transmission component 23 as a gear 232 and a rack 231, the linear motion of the connecting rod 22 can be converted into the rotational structure of the gear 232, thereby driving the limiting structure 24 to rotate. The meshing transmission between the gear 232 and the rack 231 is more stable, so the rotation of the limiting structure 24 is also more stable.
[0059] In other embodiments, the transmission assembly 23 includes a lead screw, a nut, and a guide structure. The nut is threadedly connected to the lead screw, and the guide structure is used to guide the nut to move in a straight line. The lead screw is fixedly connected to the connecting rod 22, and the connecting rod 22 drives the nut to move, thereby causing the lead screw to output rotational motion. The lead screw is fixedly connected to the limiting structure 24.
[0060] Please refer to some embodiments of this utility model. Figure 3 and Figure 5 The limiting structure 24 includes a limiting part 241 and a connecting rod 242. The limiting part 241 is used to engage and lock with the cabinet 200. One end of the connecting rod 242 is connected to the limiting part 241, and the other end of the connecting rod 242 is fixedly connected to the gear 232. The limiting part 241 is a structure that locks into the cabinet 200, and the limiting part 241 and the gear 232 are connected by the connecting rod 242.
[0061] By setting the limiting structure 24 as a limiting part 241 and a connecting rod 242, a certain distance is made between the limiting part 241 and the gear 232, so that the limiting part 241 can extend into the interior of the cabinet 200 and engage with the cabinet 200.
[0062] In some embodiments, the connecting rod 242 and the gear 232 are coaxially arranged, and the central axis of the limiting part 241 is offset from the central axis of the connecting rod 242. In this way, when the gear 232 drives the connecting rod 242 and the limiting part 241 to rotate, the end of the limiting part 241 away from the connecting rod 242 can be engaged with the cabinet 200.
[0063] Optionally, the limiting part 241 has an elongated oval structure, and the cabinet 200 has an elongated oval hole 201. When the limiting part 241 rotates to the same length direction as the elongated oval hole 201 of the cabinet 200, the limiting part 241 is completely aligned with the elongated oval hole 201 of the cabinet 200, and the limiting part 241 can disengage from the cabinet 200, and the door lock structure 100 is in the unlocked state. When the limiting part 241 rotates to a different length direction than the elongated oval hole 201 of the cabinet 200, the limiting part 241 is at least partially offset from the elongated oval hole 201 of the cabinet 200, and the limiting part 241 cannot disengage from the cabinet 200, and the door lock structure 100 is in the locked state.
[0064] In some embodiments, the limiting part 241 and the connecting rod 242 are integrally formed, and the limiting part 241 and the connecting rod 242 do not need to be installed and connected. The connecting rod 242 can be directly fixedly connected to the gear 232.
[0065] In some embodiments, the limiting part 241 is located outside the lock housing structure 10 for cooperating with the cabinet 200, and at least a portion of the connecting rod 242 is located outside the lock housing structure 10.
[0066] Please refer to some embodiments of this utility model. Figure 3 and Figure 5 The door lock structure 100 also includes a support assembly 25 for supporting the limiting structure 24. The support assembly 25 includes a sleeve structure 251 disposed on the outer periphery of the connecting rod 242 and limiting pins 252. The sleeve structure 251 is fixed to the lock housing structure 10. Multiple limiting pins 252 are circumferentially disposed on the sleeve structure 251, passing through the sleeve structure 251 and abutting against the surface of the connecting rod 242. The support assembly 25 supports the limiting structure 24. Since the limiting structure 24 is fixedly connected to the gear 232, the support assembly 25 can also support the gear 232. The support assembly 25 includes a sleeve structure 251 and a limiting pin 252. The sleeve structure 251 is located on the outer periphery of the connecting rod 242 and fixed to the lock housing structure 10. This can be understood as the connecting rod 242 extending into the sleeve structure 251, and the limiting pin 252 passing through the sleeve structure 251 and abutting against the connecting rod 242. Multiple limiting pins 252 are arranged circumferentially on the outer periphery of the connecting rod 242, providing radial support and ensuring stable rotation of the limiting structure 24 and the gear 232. Specifically, when assembling the door lock structure 100, the sleeve structure 251 is first fixed to the lock housing structure 10, then the connecting rod 242 of the limiting structure 24 is inserted into the sleeve structure 251, and finally, the gear 232 is fixedly connected to the connecting rod 242.
[0067] By providing the support component 25, the connecting rod 242 of the limiting structure 24 can be supported, thereby ensuring the stable rotation of the gear 232. Moreover, the connecting rod 242 is supported by the cooperation of the rod sleeve structure 251 and the limiting pin 252, which is low in cost and easy to install.
[0068] In some embodiments, the sleeve structure 251 has a plurality of mating holes circumferentially provided, and each limiting pin 252 is tightly fitted into the corresponding mating hole and abuts against the surface of the connecting rod 242.
[0069] In some embodiments, the sleeve structure 251 has a plurality of threaded holes circumferentially provided, and each limiting pin 252 is connected to the corresponding threaded hole and abuts against the surface of the connecting rod 242.
[0070] In other embodiments, the axle of gear 232 is supported on the lock housing structure 10 by bearings and other support components, thereby supporting gear 232 and limiting structure 24, making the rotation of gear 232 and limiting structure 24 more stable, and reducing the possibility of jamming when the first lock body assembly 20 is working.
[0071] Please refer to some embodiments of this utility model. Figure 2 and Figure 3The electric actuator 21, connecting rod 22, and transmission assembly 23 are all located inside the lock housing structure 10, while the limiting part 241 is located outside the lock housing structure 10. The limiting part 241 needs to cooperate with the cabinet 200; therefore, the limiting part 241 is located outside the lock housing structure 10, while the electric actuator 21, connecting rod 22, and transmission assembly 23 are located inside the lock housing structure 10. The lock housing structure 10 can protect these components.
[0072] In some embodiments, the second lock body assembly 30 is also disposed inside the lock housing structure 10. Understandably, the first lock body assembly 20, except for the limiting structure 24, and the second lock body assembly 30 are both disposed inside the lock housing structure 10, which makes the door lock structure 100 more integral and makes it easier to install the door body 300 structure as a whole onto the door body 300.
[0073] Please refer to some embodiments of this utility model. Figure 1 and Figure 3 The lock housing structure 10 includes a lock base plate 12 and a lock cover 11. The lock cover 11 is fixed to the lock base plate 12, so that a receiving space is formed between the lock cover 11 and the lock base plate 12. The first lock body assembly 20, except for the limiting structure 24, and the second lock body assembly 30 are both disposed in the receiving space.
[0074] Optionally, the electric actuator 21 is fixed to the locking base plate 12, and the locking base plate 12 has holes for connecting the limiting structure 24 and the gear 232.
[0075] Please refer to some embodiments of this utility model. Figure 1 The lock housing structure 10 is provided with a buckle 13, which is used to engage with the cabinet 200, thereby allowing the entire door lock structure 100 to be installed on the cabinet 200.
[0076] Please refer to some embodiments of this utility model. Figure 3 and Figure 4 One end of the connecting rod 22 has a groove 221. The extension direction of the groove 221 is different from the movement direction of the connecting rod 22. The push-pull member 32 extends into the groove 221 and can slide along the groove 221. The push-pull member 32 is located inside the groove 221. The push-pull member 32 is driven by the mechanical lock core 31 and is guided by the groove 221. Through the setting of the groove 221, the movement of the push-pull member 32 is decomposed into movement parallel to the movement direction of the connecting rod 22 and movement along the extension direction of the groove 221. In this way, the connecting rod 22 is pushed and pulled by the push-pull member 32, thereby realizing the rotation of the limiting structure 24.
[0077] By providing a groove 221 at one end of the connecting rod 22, with the extension direction of the groove 221 being different from the movement direction of the connecting rod 22, the mechanical lock cylinder 31 drives the push-pull member 32 to move within the groove 221, simultaneously pushing and pulling the connecting rod 22, thus causing the connecting rod 22 to move and thereby achieving the rotation of the limiting structure 24. It should be noted that the movement of the mechanical lock cylinder 31 is typically a rotational movement (rotated by the key 40), therefore the cooperation of the push-pull member 32 and the groove 221 is required to convert the rotational movement into the linear movement of the connecting rod 22.
[0078] In some embodiments, the slide 221 is elongated, and the length direction of the slide 221 is set at an acute or obtuse angle to the movement direction of the connecting rod 22.
[0079] In some embodiments, the push-pull member 32 is a pin structure, with one end of the push-pull member 32 fixed to the mechanical lock core 31 and the other end extending into the slide groove 221.
[0080] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The mechanical lock cylinder 31 is capable of outputting rotational motion, and the push-pull member 32 is eccentrically fixed to the rotating end of the mechanical lock cylinder 31. The mechanical lock cylinder 31 is generally driven by the key 40. After the key 40 is inserted into the mechanical lock cylinder 31, rotating the mechanical lock cylinder 31 locks or unlocks it. Therefore, the movement of the mechanical lock cylinder 31 is generally rotational. The push-pull member 32 is eccentrically fixed to the rotating end of the mechanical lock cylinder 31, meaning that the push-pull member 32 is offset from the rotation axis of the rotating end of the mechanical lock cylinder 31, allowing the push-pull member 32 to perform a non-rotational rotational motion, which can drive the connecting rod 22 to move.
[0081] By eccentrically fixing the push-pull member 32 to the rotating end of the mechanical lock core 31, the push-pull member 32 can rotate around its rotating end, thereby cooperating with the slide groove 221 to push and pull the connecting rod 22, realizing the linear movement of the connecting rod 22.
[0082] In some embodiments, the rotating end of the mechanical lock cylinder 31 is provided with a locking plate 311, and the push-pull member 32 is fixed to the locking plate 311 at a position off the rotation axis of the rotating end of the mechanical lock cylinder 31.
[0083] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The door lock structure 100 also includes a battery 53, which is electrically connected to the controller 51. Since the controller 51 is connected to the electric actuator 21, in the event of a power outage, the battery 53 can supply power to the controller 51 and the electric actuator 21. The controller 51 sends an unlocking signal to the electric actuator 21, which then drives the linkage 22 to open the door lock structure 100.
[0084] In some embodiments, battery 53 may be a button cell, cylindrical cell, etc.
[0085] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The door lock structure 100 also includes a speaker 52, which is electrically connected to the controller 51. The speaker 52 is used for voice prompts (e.g., welcome, door is open, please open the door, please close the door, welcome back next time, etc.), which can provide voice prompts to the user and enhance the user experience.
[0086] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The door lock structure 100 also includes a battery 53 and a speaker 52, both of which are electrically connected to the controller 51.
[0087] Please see Figure 6 and Figure 7 This utility model also provides an automatic vending machine cabinet, which includes a door 300, a cabinet 200, and a door lock structure 100 as described in any of the above embodiments. The door lock structure 100 is fixed to the door 300 and is used to lock the door 300 to the cabinet 200. The door lock structure 100 has an unlocked state and a locked state. In the unlocked state, the limiting structure 24 of the door lock structure 100 is disengaged from the cabinet 200. In the locked state, the limiting structure 24 of the door lock structure 100 is engaged with the cabinet 200.
[0088] The automatic vending machine cabinet provided by this utility model adopts the above-mentioned door lock structure 100. The door lock structure 100 includes a lock shell structure 10, a first lock body assembly 20, and a second lock body assembly 30. The first lock body assembly 20 includes an electric actuator 21, a connecting rod 22, and a limiting structure 24. When the electric actuator 21 is powered, it can drive the limiting structure 24 to move through the connecting rod 22, thereby realizing the electronic unlocking or unlocking of the door lock structure 100. The second lock body assembly 30 includes a mechanical lock cylinder 31 and a push-pull member 32. In the event of a power outage or when the first lock body assembly 20 is damaged, the door lock structure 100 can still be unlocked by driving the push-pull member 32 and the connecting rod 22 through the mechanical lock. Furthermore, the limiting structure 24 of the first lock body assembly 20 and the second lock body assembly 30 are respectively located at opposite ends of the connecting rod 22, making the door lock structure 100 elongated and smaller in size, allowing it to be installed in the middle of the door body 300. The door lock structure 100 can be locked and unlocked by rotating the limiting structure 24. Thus, when the door lock structure 100 is locked, if the door is pulled forcefully, there will not be excessive gaps on the upper and lower sides of the door body 300, enhancing its anti-theft effect.
[0089] In some embodiments of this utility model, the cabinet 200 has an elongated hole 201, and the limiting part 241 has an elongated oval structure. When the limiting structure 241 rotates to the point where the length direction of its elongated oval structure is the same as the length direction of the elongated hole 201 of the cabinet 200, the elongated oval structure is completely aligned with the elongated hole 201 of the cabinet 200, and the elongated oval structure can detach from the cabinet 200, and the door lock structure 100 is in the unlocked state. When the limiting part 241 rotates to the point where the length direction of its elongated oval structure is different from the length direction of the elongated hole 201 of the cabinet 200, the elongated oval structure is at least partially offset from the elongated hole 201 of the cabinet 200, the limiting structure 24 cannot detach from the cabinet 200, and the door lock structure 100 is in the locked state.
[0090] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
