Description

Technical Field

[0001] The invention relates to a locking component, in particular to a locking mechanism and a storage cabinet. Background Art

[0002] Locking mechanisms are core components for ensuring the safety of items and are widely used in safes, lockers, and other equipment. Currently, most common locking mechanisms use electromagnetic locks to achieve locking and unlocking functions. Their typical structure includes a solenoid valve, a valve plug, and a spring. The spring's force extends the valve plug to lock the item. To unlock, the solenoid valve generates an attractive force that overcomes the spring's force, pulling the valve plug back in to release the lock.

[0003] Specifically, the locking principle of the existing electromagnetic lock is: after the valve bolt is extended under the action of the spring, it will abut or block the locking components such as the lock tongue, restricting the rotation of the locking components, thereby achieving the locking of the cabinet door and the cabinet body; when unlocking, the solenoid valve needs to be continuously energized to generate attraction, keeping the valve bolt in the retracted state, releasing the restriction on the locking components, and allowing the cabinet door to be opened.

[0004] However, the above prior art has the following significant drawbacks:

[0005] Insufficient stability: Because the spring force must match the solenoid valve's attraction (if the force is too strong, the solenoid valve will have difficulty retracting the valve plug), the spring force is typically too low. When the equipment is subject to external disturbances such as vibration or shaking, the valve plug can easily overcome the small spring force and unexpectedly retract, causing the locking component to mislock and seriously affecting the reliability of the locking mechanism.

[0006] High energy consumption: To maintain the unlocked state, the solenoid valve needs to be continuously energized to maintain the attraction to the valve plug, which will result in high energy consumption. Especially for battery-powered equipment, frequent power consumption will significantly shorten the battery life and increase maintenance costs. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the object of the present invention is to provide a locking mechanism and a locker that can reduce power consumption and make the locking state more stable.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A locking mechanism, characterized in that it includes:

[0009] Lock box;

[0010] A locking member rotatably connected to the lock box, wherein a portion of the locking member is exposed from the lock box to cooperate with an external structure to achieve locking;

[0011] a limiting member, rotatably connected to the lock box;

[0012] a driving member, configured to drive the restricting member to rotate so as to release the restriction on the locking member;

[0013] The driving member is an electromagnetic driving member, which drives the limiting member to rotate by the attraction generated by energizing the electromagnetic driving member;

[0014] The interactive component is used for user interaction and controls the driving component to be powered on and perform driving actions after the interaction;

[0015] In which, when the locking member is in a locked state, the limiting member abuts against the edge of the locking member under the action of gravity to limit its reverse rotation; when the locking member is unlocked, the driving member drives the limiting member to rotate to release the restriction on the locking member, and the driving member only generates driving force during the unlocking process; the limiting member is provided with a counterweight component, and the limiting member drives the limiting member to rotate and abut against the edge of the locking member through the gravity of the counterweight component to limit its reverse rotation.

[0016] As a further improvement of the present invention, a lock tongue is provided on the locking member, and a protruding mating portion is provided on the portion of the lock tongue exposed from the lock box. The mating portion is used to abut against an edge of the external structure to drive the locking member to rotate, thereby locking the external structure.

[0017] As a further improvement of the present invention, when the locking member is unlocked, the locking member contacts the external structure and rotates, and the mating portion extends along with the rotation of the locking member, waiting for the next mating edge of the external structure to abut.

[0018] As a further improvement of the present invention, the matching portion is hook-shaped and is used to match and abut against an edge of the external structure.

[0019] As a further improvement of the present invention, the lock box is provided with a notch at a position corresponding to the matching portion. When the locking member is rotated to lock, the matching portion is at least partially accommodated in the notch; when the locking member is unlocked, the matching portion extends from the notch.

[0020] As a further improvement of the present invention, when the locking member is in a locked state, the matching portion is completely accommodated in the notch.

[0021] As a further improvement of the present invention, the limiting member is further provided with an abutting portion, and the locking member is provided with an abutting groove at a position corresponding to the abutting portion. When the limiting member abuts against the locking member, the abutting portion abuts and cooperates with the abutting groove.

[0022] As a further improvement of the present invention, the abutting portion is formed by bending the limiting member.

[0023] As a further improvement of the present invention, the abutting portion is further extended to form a counterweight portion.

[0024] A storage cabinet comprises a cabinet body and a cabinet door rotatably mounted on the cabinet body, wherein the cabinet door is provided with a locking mechanism as described in any one of the above items, and the locking mechanism is used to lock the cabinet door to the cabinet body and moves with the cabinet door.

[0025] The beneficial effects of the present invention are that the limiting part relies on the gravity of the counterweight part to limit the locking part, replacing the traditional spring structure, effectively avoiding the problem of vibration mislocking caused by unstable spring elastic force, and significantly improving the stability of the locked state; the electromagnetic drive part is only powered on briefly during the unlocking process, without the need for continuous energy consumption, greatly reducing energy consumption, and is especially suitable for battery-powered scenarios; the interactive component facilitates users to trigger unlocking through various methods (such as passwords, fingerprints, etc.), combined with the automatic locking design of the mechanical structure, the overall operation is convenient and reliable.

[0035] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0036] Reference Figure 1-8 As shown, a locking mechanism comprises:

[0037] Lock box 1;

[0038] The locking member 2 is rotatably connected to the lock box 1, and a portion of the structure of the locking member 2 is exposed from the lock box 1 to cooperate with the external structure to achieve locking;

[0039] The limiting member 3 is rotatably connected to the lock box 1;

[0040] A driving member 4 is used to drive the limiting member 3 to rotate so as to release the restriction on the locking member 2;

[0041] The driving member 4 is an electromagnetic driving member 4, which drives the limiting member 3 to rotate by the attraction force generated by power supply;

[0042] The interactive component is used for user interaction and controls the driving element 4 to be powered on and perform driving actions after the interaction;

[0043] Among them, when the locking member 2 is in a locked state, the limiting member 3 abuts the edge of the locking member 2 under the action of gravity to limit its reverse rotation; when the locking member 2 is unlocked, the driving member 4 drives the limiting member 3 to rotate to release the restriction on the locking member 2, and the driving member 4 only generates driving force during the unlocking process; the limiting member 3 is provided with a counterweight component 5, and the limiting member 3 drives the limiting member 3 to rotate and abut the edge of the locking member 2 through the gravity of the counterweight component 5 to limit its reverse rotation.

[0044] The interactive component can be an electronic password disk, a fingerprint module, an RFID module, a key module, etc., which can be used for user interaction and can generate a switch signal after the interaction to control whether the driving part 4 is powered on or not.

[0045] The lock box 1 is fixedly installed at a preset position of an external device (such as a cabinet door) by bolts or snaps, and the locking member 2 is rotatably connected to the lock box 1 through a first rotating shaft, and its part exposed from the lock box 1 can contact and cooperate with an external structure (such as the edge of a cabinet); the limiting member 3 is rotatably connected to the lock box 1 through a second rotating shaft; the driving member 4 (electromagnetic driving member 4) is fixedly installed on one side of the lock box 1 close to the limiting member 3, and its output end corresponds to the force-bearing part of the limiting member 3. The counterweight component 5 of the limiting member 3 is fixed at the end thereof away from the second rotating shaft. The counterweight effect of the counterweight component 5 allows the position where the limiting member 3 cooperates with the locking member 2 to maintain a trend of moving toward the locking member 2.

[0046] When the locking mechanism is in the locked state, the limiting member 3 rotates around the second rotating axis under the action of the gravity of the counterweight component 5, abutting between the locking member 2 and the cabinet door, limiting the locking member 2 from rotating in the opposite direction around the first rotating axis. Even if it is vibrated or shaken, the gravity torque of the counterweight component 5 can resist the external force, preventing the limiting member 3 from disengaging from the locking member 2 and preventing mislocking. The stability is significantly better than the existing spring structure.

[0047] When it is necessary to unlock, the driving member 4 (the electromagnetic driving member 4) is powered for a short time to generate an attractive force, which attracts the limiting member 3 to rotate around the second rotation shaft in a direction close to the driving member 4, so as to be separated from the position between the locking member 2 and the cabinet door, and the limitation is released; at this time, the locking member 2 can be rotated around the first rotation shaft under the driving of the external structure, so as to realize unlocking. The driving member 4 can be powered off after the unlocking action is completed, and it is not necessary to continuously supply power, which is especially suitable for the battery power supply scene. When the locking member 2 cooperates with the cabinet door to lock, a gap can be formed between the locking member 2 and the cabinet door under the rotating action of the locking member 2, and when the size of the gap can allow the limiting member 3 to enter, the limiting member 3 rotates into the gap under the action of gravity, limits the reverse rotation of the locking member 2, and then realizes locking, and at this time, the power consumption can be significantly reduced.

[0048] In an optional specific scheme, the locking member 2 is provided with a lock tongue 6, and a protruding matching part 7 is arranged on the part of the lock tongue 6 exposed from the lock box 1, and the matching part 7 is used for abutting against the edge of the external structure to drive the locking member 2 to rotate, so as to lock the external structure.

[0049] The lock tongue 6 and the locking member 2 are fixed by welding or one-piece forming, so as to ensure that the two are synchronously rotated. When the external structure (such as the edge of the cabinet body) moves relative to the direction of the lock tongue 6, the edge abuts against the matching part 7, drives the lock tongue 6 and the locking member 2 to rotate around the first rotation shaft, until the lock tongue 6 is clamped with the edge of the external structure, and at the same time, the limiting member 3 limits the reverse rotation of the locking member 2, so as to realize locking. The arrangement of the matching part 7 facilitates the cooperation with the external structure to drive the locking member 2 to rotate, and it is not necessary to additionally power to control the locking.

[0050] Preferably, when the locking member 2 is unlocked, the locking member 2 contacts the external structure to rotate, and the matching part 7 extends out with the locking member 2 to rotate, which is used for waiting for the next abutment with the edge of the external structure. This structure can drive the locking member 2 to rotate to realize locking without additional operation, simplifies the operation process, and improves the use convenience. At the same time, the extended state of the matching part 7 is guaranteed by the rotation limiting of the locking member 2, and the structure is reliable and not easy to be misoperated by external force.

[0051] As an optional further arrangement, the matching part 7 is hook-shaped, and is used for abutting against the edge of the external structure. The hook-shaped structure can make the cooperation more stable and easier to form cooperation.

[0052] In a scheme capable of reducing the influence of the matching part 7 on the locking process and the locked state, the lock box 1 is provided with a notch 8 corresponding to the position of the matching part 7, and when the locking member 2 rotates to lock, the matching part 7 is at least partially accommodated in the notch 8; when the locking member 2 is unlocked, the matching part 7 extends out of the notch 8.

[0053] During locking, the mating portion 7 rotates with the locking member 2 and gradually enters the notch 8. When fully locked, the outer surface of the mating portion 7 is flush with the outer surface of the lock box 1, preventing it from protruding outside the lock box 1 and interfering with external structures (such as the fit between the cabinet door and the cabinet body). When unlocking, the mating portion 7 rotates with the locking member 2 and extends out of the notch 8. This structure uses the notch 8 to guide the mating portion 7 in both its storage and extension, eliminating the structural interference caused by the protrusion of the lock tongue 6 and improving the overall compactness of the structure. Preferably, when the locking member 2 is locked, the mating portion 7 is completely contained in the notch 8.

[0054] In addition, in order to improve the stability of the abutment between the limiting member 3 and the locking member 2, an abutment portion 9 is also provided on the limiting member 3, and an abutment groove 10 is provided on the locking member 2 at a position corresponding to the abutment portion 9. When the limiting member 3 abuts on the locking member 2, the abutment portion 9 and the abutment groove 10 abut and cooperate.

[0055] The abutment portion 9 is a protruding structure of the limiting member 3 toward the locking member 2, and the abutment groove 10 is a groove on the edge of the locking member 2. In the unlocked state, the limiting member 3 rotates under the action of the counterweight, and the abutment portion 9 abuts the groove 10, increasing the abutment area.

[0056] In order to facilitate processing, the abutment portion 9 is formed by bending the limiting member 3 .

[0057] In an optional embodiment, the abutment portion 9 further extends to form a counterweight portion 11. After bending, the abutment portion 9 extends away from the second rotation axis, forming a long strip of counterweight portion 11. The counterweight portion 11 is integrally formed with the abutment portion 9, serving both as an abutment structure and providing a counterweight by extending its length. When the restricting member 3 rotates, the weight of the counterweight portion 11 further increases the tendency of the restricting member 3 to rotate toward the locking member 2, improving locking reliability. Furthermore, the integrated structure reduces the number of components and simplifies the structural design.

[0058] The above mentioned is a locking mechanism. In specific applications, the following solutions can also be formed:

[0059] A storage cabinet includes a cabinet body and a cabinet door rotatably mounted on the cabinet body. The cabinet door is provided with a locking mechanism as described above, which is used to lock the cabinet door to the cabinet body and moves with the cabinet door; a locking member 2 is used to cooperate with the edge of the cabinet body corresponding to the cabinet door to lock or unlock.

[0060] The cabinet body is a metal or wooden box, and the cabinet door is rotatably connected to the cabinet body through hinges. The lock box 1 of the locking mechanism is fixed to the inner side of the cabinet door (corresponding to the position of the cabinet edge) by screws, and the part of the locking member 2 exposed from the lock box 1 faces the cabinet edge.

[0061] The locking member 2 is used to cooperate with the edge of the corresponding cabinet door of the cabinet body; the matching part 7 is used to cooperate with the edge of the corresponding cabinet door of the cabinet body to abut and drive the locking member 2 to rotate, so that the locking tongue 6 hooks the cabinet body edge to lock the cabinet door; when the cabinet door is opened, the locking tongue 6 abuts against the cabinet body and drives the locking member 2 to rotate, and the matching part 7 is driven to extend out. During the closing process of the cabinet door, the cabinet body edge contacts the matching part 7 of the locking tongue 6, drives the locking member 2 to rotate, the locking tongue 6 is hooked on the inside of the cabinet body edge with the rotation, and the locking is realized, at this time, the matching part 7 partially or completely enters the notch 8; when the cabinet door is unlocked and opened, the cabinet door rotates around the hinge, the cabinet body edge reversely pushes the locking tongue 6, drives the locking member 2 to rotate, the matching part 7 extends out with the locking tongue 6, and waits for the next time of closing to contact with the cabinet body edge. The process does not need to manually operate the locking mechanism, and automatic locking and unlocking preparation are realized.

[0062] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical scheme falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application are also considered as the protection scope of the present application.
