Description

Technical Field

[0001] The present invention relates to the technical field of unmanned vending equipment, and in particular to an electric bolt lock for a vending cabinet. Background Art

[0002] In the current business environment, vending machines are a common self-service sales equipment and are widely used in various places, such as shopping malls, airports, schools, etc. The use of vending machines provides consumers with a convenient shopping experience and also saves labor costs for merchants. As an important locking device for the doors of vending machines, electric bolt locks play a key role in ensuring the safety of goods and the normal conduct of transactions. However, in actual use, electric bolt locks face some technical problems. Since vending machines are usually placed in public places, they may encounter some bad behaviors or even violent destruction. In the case of violent unlocking, strong external forces directly act on the lock tongue, which may cause the lock tongue to deform, break or otherwise be damaged. This damage will not only cause the electric bolt lock to lose its normal locking function, but may also cause a series of subsequent problems. Once the lock tongue is damaged, the door of the vending machine may not be opened normally. This will not only affect consumers' normal purchase of goods and cause economic losses to merchants, but also cause great inconvenience when the vending machine needs to be maintained, restocked or cleaned up because the door cannot be opened. In addition, if the problem of the door being unable to be opened is not solved in time, the goods in the cabinet may deteriorate and be damaged because they cannot be taken out for a long time, further aggravating the loss. In order to solve the problem that violent unlocking may cause damage to the lock tongue and difficulty in opening the cabinet door normally, it is necessary to improve and innovate the electric bolt lock of the vending machine, enhance its ability to resist violent destruction, and ensure that the cabinet door can be opened and closed normally under various circumstances.

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 8In an embodiment of the present invention, an electric bolt lock for a vending machine is proposed, which is used to lock between a door body 1 and a frame body 2 of the vending machine, wherein the door direction of the vending machine is defined as the longitudinal positive direction, the opening direction of the door body 1 is also along the longitudinal positive direction, the frame body 2 has a longitudinal first slide groove 201, the door body 1 has a transverse first locking groove 101, and also includes a lock body 3 and a lock tongue 4, the lock tongue 4 is slidably arranged in the lock body 3, the sliding direction is along the transverse direction, and the lock tongue 4 is configured to enter or leave the first locking groove 101 after sliding; the sliding shell 5 is slidably arranged in the first slide groove 201, and the lock body 3 is arranged in the sliding shell 5; one end of the first elastic member 6 acts on the sliding shell 5, and the other end acts on the side wall of the first slide groove 201, providing a force for the sliding shell 5 to slide in the longitudinal negative direction.

[0023] In this embodiment, the door body 1 and the frame body 2 of the vending cabinet constitute a cabinet structure. The first slide groove 201 on the frame body 2 is arranged longitudinally, and the first locking groove 101 on the door body 1 is opened transversely. The lock tongue 4 can slide transversely in the lock body 3. When locked normally, the lock tongue 4 slides into the first locking groove 101 to achieve locking. The sliding shell 5 can slide longitudinally in the first slide groove 201, and the lock body 3 is installed inside the sliding shell 5. The first elastic member 6 is arranged between the sliding shell 5 and the side wall of the first slide groove 201, and is usually a compression spring. When violent unlocking occurs, a strong external force acts on the lock tongue 4. Since the lock body 3 is arranged in the sliding shell 5 that can slide longitudinally, and the first elastic member 6 provides buffering, the longitudinal impact force on the lock tongue 4 will be transmitted to the sliding shell 5, so that the sliding shell 5 slides in the longitudinal negative direction along the first slide groove 201, thereby buffering and dispersing the impact force and reducing direct damage to the lock tongue 4. For example, when someone uses a tool such as a crowbar to forcibly pry the lock, the longitudinal force applied to the lock tongue 4 causes the sliding shell 5 to compress the first elastic member 6 and slide backward. The risk of deformation or breakage of the lock tongue 4 due to violent unlocking is reduced, and the service life of the lock is extended. The situation in which the cabinet door is difficult to open normally due to damage to the lock tongue 4 is reduced, ensuring the normal use of the vending cabinet. In addition, the frame 2 mentioned in this solution does not specifically refer to the entire frame, but can also be used as a local integrated component and installed on the pre-installed hole of the vending cabinet. Such a design makes the installation of the frame 2 more flexible and convenient, and can adapt to the structure and size of different vending cabinets.

[0024] Furthermore, the frame 2 has a second sliding groove 202 along the horizontal direction, the door body 1 also has a second locking groove 102 along the horizontal direction, and also includes a first secondary lock element 7, the first secondary lock element 7 is slidably arranged in the second sliding groove 202, and the first secondary lock element 7 is configured to enter or leave the second locking groove 102 at one end after sliding; one end of the first connecting rod 8 is hinged to the sliding shell 5, and the other end is hinged to one end of the first secondary lock element 7. After the sliding shell 5 slides horizontally, the first secondary lock element 7 is driven to extend or retract through the first connecting rod 8.

[0025] In this embodiment, under normal circumstances, when the lock tongue 4 is inserted into the first locking groove 101 to achieve locking, the sliding shell 5 is in the initial position. At this time, one end of the first secondary lock element 7 is located outside the second locking groove 102. When unlocking is required, the lock tongue 4 slides out of the first locking groove 101, and the sliding shell 5 slides in the longitudinal negative direction, and the first secondary lock element 7 is driven to retract through the first connecting rod 8, so that one end of it leaves the second locking groove 102, thereby achieving unlocking. When subjected to violent impact, the longitudinal sliding of the sliding shell 5 will also drive the first secondary lock element 7 to move through the first connecting rod 8, dispersing part of the impact force. For example, when the impact force of violent unlocking causes the sliding shell 5 to slide backward, the first connecting rod 8 will push the first secondary lock element 7 to extend. By adding the first secondary lock element 7, the locking reliability of the vending cabinet is improved. When violent impact occurs, the first secondary lock element 7 cooperates with the main lock structure to jointly buffer the impact force and further protect the lock structure. The impact force is dispersed and the risk of damage to the lock structure is reduced.

[0026] Furthermore, the frame 2 also has a third slide groove 203, which is longitudinally located on the positive side of the longitudinal direction of the first slide groove 201, and the first slide groove 201 is connected to the third slide groove 203. The sliding shell 5 has a pushing portion 501 and also includes a first pushing member 9. The first pushing member 9 is slidably arranged in the third slide groove 203. After the sliding shell 5 slides, it pushes the first pushing member 9 to slide; one end of the second elastic member 10 acts on the side wall of the third slide groove 203, and the other end acts on the first pushing member 9, providing a force for the first pushing member 9 to slide in the negative direction of the longitudinal direction.

[0027] In this embodiment, under normal circumstances, when the force of pulling the cabinet door is small, the front structure, such as the first elastic member 6, the first auxiliary lock member 7 and the first connecting rod 8, can play a certain buffering and protective role to prevent the lock tongue 4 from being damaged. When encountering a sufficiently large violent unlocking force, the sliding shell 5 slides along the first sliding groove 201 in the negative direction of the longitudinal direction, and the pushing part 501 on the sliding shell 5 contacts and pushes the first pushing member 9 to slide in the third sliding groove 203. The second elastic member 10 is usually a compression spring, one end of which is connected to the side wall of the third sliding groove 203, and the other end is connected to the first pushing member 9, providing the first pushing member 9 with a restoring force to slide in the negative direction of the longitudinal direction. When the violent impact force is extremely large and sufficient to overcome the buffering of the front structure, the sliding shell 5 slides backward significantly, and the pushing part 501 strongly pushes the first pushing member 9 to overcome the elastic force of the second elastic member 10 and slide upward. When the impact force disappears, the elastic force of the second elastic member 10 causes the first pushing member 9 to slide downward and reset. For different degrees of pulling force, from small force to extremely large force of violent unlocking, different structures are used to achieve buffer protection and improve overall safety. When facing a sufficiently large force of violent unlocking, it can effectively disperse and absorb energy to protect the lock structure. No matter how strong the impact is, with the help of the second elastic member 10, the relevant components can be automatically reset to maintain the normal function of the lock. Through multi-level protection, the damage to the lock structure caused by violent unlocking is reduced, and the service life of the electric bolt lock is extended.

[0028] Further, the frame 2 has a fourth slide groove 204 along the horizontal direction, the fourth slide groove 204 penetrates the first slide groove 201, and the fourth slide groove 204 is divided into a fourth outer slide groove 205 and a fourth inner slide groove 206 by the first slide groove 201; the first pusher 9 has a clamping portion 901, the clamping portion 901 is slidably arranged in the first slide groove 201, and the clamping portion 901 has a connecting groove 902 along the horizontal direction, after the first pusher 9 slides longitudinally, the connecting groove 902 connects or cancels the fourth outer slide groove 205 and the fourth inner slide groove 206; The door body 1 also has a third locking groove 103 along the horizontal direction, and the third locking groove 103 is located on one side of the second locking groove 102, and also includes: the second secondary lock piece 11 is slidably arranged in the fourth outer slide groove 205, and enters or leaves the third locking groove 103 after sliding; the trigger block 12 is arranged in the fourth inner slide groove 206; one end of the third elastic member 13 acts on the inner wall of the fourth inner slide groove 206, and the other end acts on the trigger block 12, providing a force for the trigger block 12 to slide in the direction of the fourth outer slide groove 205; the transmission block 14 is arranged in the connecting groove 902. After the connecting groove 902 connects the fourth outer slide groove 205 and the fourth inner slide groove 206, the trigger block 12 pushes the transmission block 14 and drives the second secondary lock piece 11 to slide into the third locking groove 103, and is also used to limit the first push member 9.

[0029] In this embodiment, under normal circumstances, when the pulling force on the cabinet door is small, each component is in the initial state, and the second secondary lock member 11 does not enter the third locking groove 103. When a sufficiently large malicious door opening force is detected, the sliding shell 5 slides significantly to push the first push member 9 to slide longitudinally, so that the connecting groove 902 connects the fourth outer sliding groove 205 and the fourth inner sliding groove 206. At this time, under the action of the third elastic member 13, the trigger block 12 pushes the transmission block 14, driving the second secondary lock member 11 to slide into the third locking groove 103, and completely locks the cabinet door. For example, when the force of violent unlocking is extremely large, the positioning portion 901 of the first push member 9 moves, the connecting groove 902 aligns with the inner and outer sliding grooves, and the trigger block 12 quickly pushes the transmission block 14, so that the second secondary lock member 11 is inserted into the third locking groove 103. On the one hand, this solution can actively lock the cabinet door completely when a large malicious door opening force is detected, thereby enhancing safety. Through the coordinated action of each component, the severity of malicious door opening can be accurately judged and responded to. In addition, the locking mechanism is only triggered when a certain force threshold is reached, avoiding misjudgment and misoperation. After locking, the staff needs to check and reset it, which helps to find out the situation and take corresponding measures. It greatly increases the difficulty of violent unlocking and effectively protects the items in the vending machine.

[0030] Furthermore, one end of the locking portion 901 has a sliding locking portion 903, the sliding shell 5 has a longitudinal fifth sliding groove 502, the sliding locking portion 903 is slidably arranged in the fifth sliding groove 502, and one side of the longitudinal positive direction of the fifth sliding groove 502 has a limiting portion 503, and the sliding locking portion 903 is configured to abut or cancel the abutment with the limiting portion 503 after sliding.

[0031] In this embodiment, the sliding clamping part 903 at one end of the clamping part 901 slides in the fifth slide groove 502 of the sliding shell 5. In a normal state, the sliding clamping part 903 is located in the fifth slide groove 502 and does not abut against the limiting part 503. When the second secondary lock 11 is triggered and locked, the sliding clamping part 903 slides in the fifth slide groove 502 to abut against the limiting part 503, thereby limiting the maximum spacing between the sliding shell 5 and the first pusher 9, so that the relative position of the two is fixed. This means that when the second secondary lock 11 is triggered, the first secondary lock 7 will also remain in the extended locking state, and the two work at the same time, ensuring a more perfect locking effect. When the second secondary lock 11 is activated due to violent unlocking, the sliding clamping part 903 slides accordingly and finally abuts against the limiting part 503, so that the relative position of the sliding shell 5 and the first pusher 9 is stable, ensuring that the first secondary lock 7 and the second secondary lock 11 work together to play a locking role. The first secondary lock 7 and the second secondary lock 11 work at the same time, enhancing the locking effect and preventing violent cracking. The perfect locking mechanism can effectively deal with various violent unlocking situations and ensure the safety of the vending machine.

[0032] Furthermore, the lock body 3 has a sixth transverse slide groove 301 inside, and the lock tongue 4 is slidably set in the sixth slide groove 301. It also includes a swinging transmission member 15, which is swingingly set in the lock body 3; one end of the second pushing member 16 is swingingly set on the swinging transmission member 15, and the other end abuts against the lock tongue 4. The second pushing member 16 is configured to push the lock tongue 4 to slide after being driven to move by the swinging transmission member 15.

[0033] In this embodiment, in normal unlocking and locking operations, when the swing transmission member 15 swings, the second pusher 16 is driven to move. Since the second pusher 16 abuts against the lock tongue 4, its movement will push the lock tongue 4 to slide in the sixth slide groove 301, thereby realizing the in-and-out movement of the lock tongue 4. For example, when locking is required, the swing transmission member 15 swings, driving the second pusher 16 to push the lock tongue 4 to slide out and enter the locking groove; when unlocking, the swing transmission member 15 swings in the opposite direction, driving the second pusher 16 to retract the lock tongue 4. Through the cooperation of the swing transmission member 15 and the second pusher 16, stable transmission is achieved, ensuring that the lock tongue 4 moves accurately and reliably. The internal structure is reasonably designed, occupies a small space, and is conducive to the miniaturization of the lock body 3. The sliding of the lock tongue 4 is smoother, and the efficiency of unlocking and locking is improved. Energy loss is reduced, and the efficiency and accuracy of power transmission are improved. The probability of failure is reduced, and the service life of the electric bolt lock is extended.

[0034] Furthermore, the locking tongue 4 has a groove portion 401 , and the second pushing member 16 has a pushing clamping portion 1601 , which is located in the groove portion 401 , and is configured to abut against the side wall of the groove portion 401 after being driven to move by the swing transmission member 15 .

[0035] In this embodiment, the lock tongue 4 is provided with a groove portion 401, and the second pusher 16 has a push clamping portion 1601, and the push clamping portion 1601 is located in the groove portion 401. During operation, when the swing transmission member 15 drives the second pusher 16 to move, the push clamping portion 1601 will abut against the side wall of the groove portion 401. For example, during the locking process, the swing transmission member 15 moves, so that the push clamping portion 1601 abuts against one side wall of the groove portion 401, thereby pushing the lock tongue 4 to extend; when unlocking, the push clamping portion 1601 abuts against the other side wall of the groove portion 401, driving the lock tongue 4 to retract. The cooperation between the push clamping portion 1601 and the groove portion 401 can accurately control the moving direction and distance of the lock tongue 4. Reduce the shaking and deviation of the lock tongue 4 during the sliding process, and improve the stability of the locking. The direct and effective abutment method reduces energy loss and improves transmission efficiency. Reasonable use of space makes the internal structure of the lock body more compact.

[0036] Furthermore, it also includes a driving member 17, which is lifted and slidably arranged in the lock body 3. One end of the swing transmission member 15 is hinged to the driving member 17, and the other end is hinged to the second pushing member 16. The driving member 17 is configured to drive the swing transmission member 15 to swing after lifting and sliding.

[0037] In this embodiment, the driving member 17 can be lifted and slid in the lock body 3. One end of the swing transmission member 15 is hinged to the driving member 17, and the other end is hinged to the second pusher 16. When performing unlocking or locking operations, the driving member 17 is lifted and slid. For example, when locking, the driving member 17 descends, drives the swing transmission member 15 to swing, and then pushes the lock tongue 4 out through the second pusher 16; when unlocking, the driving member 17 rises, drives the swing transmission member 15 to swing in the opposite direction, and retracts the lock tongue 4. The lifting and sliding operations of the driving member 17 are simple, and it is convenient to control the opening and closing of the lock. The transmission of force is achieved by means of hinges, making the transmission more flexible and efficient. The jamming and instability factors in the transmission process are reduced, and the reliability of the lock is improved.

[0038] Furthermore, the lock body 3 further has a seventh sliding groove 302 in the transverse direction, and the middle section of the swing transmission member 15 has a first sliding portion 1501 , which is slidably disposed in the seventh sliding groove 302 .

[0039] In this embodiment, a seventh transverse slide groove 302 is provided inside the lock body 3, and a first sliding part 1501 is located in the middle section of the swing transmission member 15. During the operation of the lock, when the swing transmission member 15 swings, the first sliding part 1501 slides in the seventh slide groove 302. For example, when the driving member 17 drives the swing transmission member 15 to swing, the first sliding part 1501 slides smoothly along the seventh slide groove 302 to ensure the accuracy and stability of the movement of the swing transmission member 15. The cooperation between the seventh slide groove 302 and the first sliding part 1501 ensures that the swing position of the swing transmission member 15 is accurate. Reduce the wear between the components and extend the service life of the swing transmission member 15. The stable sliding structure helps to improve the reliability of the operation of the entire lock body 3.

[0040] Furthermore, the second push member 16 has a second sliding portion 1602 , and the lock body 3 further has an eighth sliding groove 303 along the horizontal direction. The eighth sliding groove 303 is located below the seventh sliding groove 302 , and the second sliding portion 1602 is slidably disposed in the eighth sliding groove 303 .
