[0035] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0036] In the description of the present invention, 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 direct connection, or an indirect connection 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.

[0037] like Figures 1 to 7 As shown in FIG. 1 , in an exemplary embodiment of the high-security refrigerator of the present invention, the refrigerator comprises a cabinet body 1, a lock body 2 and a cabinet door 3 are mounted on the cabinet body 1, and a lock tongue 21 is provided on the lock body 2 for locking the cabinet door 3. Figure 7 As shown, the lock tongue 21 extends out and is inserted into the insertion slot 32 provided by the lock hook 31 installed on the cabinet door 3, so that the lock hook 32 can be prevented from moving away from the lock tongue 21, and the cabinet door 3 is limited in the closed state. The lock tongue 21 is pulled out of the insertion slot 32, and the limit on the lock hook 32 can be eliminated, and the cabinet door 3 can be unlocked so that it can be opened.

[0038] The cabinet body 1 has a storage space 11 for accommodating goods. The goods are refrigerated or frozen in the storage space 11. The lock body 2 is located in the storage space 11 of the cabinet body 1, so that it is located on the side wall of the cabinet body 1 facing the storage space 11 and directly contacts the cold air in the storage space 11. Therefore, after the cabinet door 3 is closed and locked by the door lock, the lock body 2 is locked inside the refrigerator to avoid being exposed to the outside, thereby reducing the risk of damage to the door lock and loss of goods.

[0039] A trigger 4 is slidably mounted in the lock housing 22 of the lock body 2. The trigger 4 is connected to the lock tongue 21 and extends out through an operation window 23 provided in the lock housing 22. The operation window 23 allows the trigger 4 to be exposed in the storage space 11, and the trapped person in the refrigerator can touch the trigger 4 to manually push or toggle it. The trigger 4 is manually operated to slide, and since it is connected to the lock tongue 21, the sliding trigger 4 drives and pulls up the lock tongue 21, thereby pulling out the lock tongue 21 and releasing the lock of the cabinet door 3.

[0040] Specifically, when a child accidentally enters and is locked in the refrigerator, the child can operate the trigger member 4 in the refrigerator by himself, and pull the lock tongue 21 by sliding the trigger member 4. The lock tongue 21 is pulled out of the lock hole of the cabinet door 3 or the plug-in slot 32 of the lock hook 31 on the cabinet door 3 under the pulling of the trigger member 4, eliminating the limitation of the lock tongue 21 on the cabinet door 3, that is, unlocking the cabinet door 3, and the child can push the cabinet door 3 from the inside to the outside to escape from the refrigerator.

[0041] In the above-mentioned illustrative embodiment, the lock body 2 in the high-security refrigerator is provided with a trigger member 4, and the trigger member 4 can be touched in the internal space of the cabinet body 1 through the operating window 23, so that it can be manually operated to slide, and then the trigger member 4 can drive the lock tongue 21, so that when a child accidentally enters and is locked in the refrigerator, the child can operate the trigger member 4 inside, thereby eliminating the lock of the cabinet door 3 and escaping by himself, eliminating the safety hazard caused by children being accidentally locked in the refrigerator, improving the safety of the refrigerator under unmanned management, and solving the problem of the risk of children being accidentally locked inside the current smart refrigerator.

[0042] In order to drive the lock tongue 21, a driving element 5 is installed in the lock housing 22 of the lock body 2. Figure 7 As shown, the driving element 5 has a valve body 51, and the valve body 51 has an electromagnet. The lock tongue 21 is slidably installed in the through hole 24 set in the lock shell 22, and the electromagnetic shaft 52 fixedly installed at the inner end thereof is slidably installed in the valve body 51, so that the electromagnet drives the electromagnetic shaft 52 to move axially through the electromagnetic force, thereby realizing the driving of the extension and contraction of the lock tongue 21. The electromagnetic drive mode enables the electromagnetic shaft 52 to pass through the valve body 51, so that as a part of the lock tongue 21, it is connected to the trigger member 4 on one side of the driving element 5, thereby realizing the connection between the lock tongue 21 and the trigger member 4.

[0043] A heating wire is installed in the lock housing to heat the lock tongue to prevent it from freezing and ensure smooth expansion and contraction. A sealing ring is installed on the lock tongue to prevent water vapor from entering the lock housing through the gap outside the lock tongue and ensure the stability of the electronic components.

[0044] In some embodiments, Figures 5 to 6 As shown, the trigger member 4 has a driving plate 41 , and a linkage seat 6 is fixedly mounted on the lock tongue 21 , and the linkage seat is arranged on the upper side of the driving plate 41 .

[0045] The trigger member 4 falls and rests on a structure or installed component arranged in the lock housing 22. When the trigger member 4 is manually pulled up, the driving plate 41 pushes the linkage seat 6 to pull up the lock tongue 21 to make it out of the lock hole or the plug-in slot, thereby eliminating the lock on the cabinet door 3 and realizing manual unlocking of the cabinet door 3.

[0046] When the driving element 5 drives the lock tongue 21 to extend and lock the cabinet door 3, the linkage seat 6 is pressed on the driving plate 41; when the driving element 5 drives the lock tongue 21 to pull up and release the lock of the cabinet door 3, the linkage seat 6 rises accordingly, breaks away from the contact with the driving plate 41, and rises to the space above it. The trigger member 4 remains stationary, avoiding the accelerated wear of the trigger member 4 due to frequent sliding due to continuous movement with the lock tongue 21, thereby improving the service life of the trigger member 4.

[0047] In some embodiments, one side of the trigger member 4 is slidably mounted on a guide rail 25 provided on the inner wall of the corresponding side of the lock housing 22, and the other side surface is attached to the inner wall of the corresponding side of the lock housing 22. Under the limiting action of the inner wall of one side of the lock housing 22, the trigger member 4 is pressed on the guide rail 25 on the other side, and the trigger member 4 is limited in a first direction. And due to the cooperation between the trigger member 4 and the guide rail 25, the guide rail 25 limits the trigger member 4 in a second direction perpendicular to the first direction. The trigger member 4 is limited in two vertical directions, so that it is stably installed in the lock housing 22 and can only slide in the direction of the guide rail 25.

[0048] The first mating surface 61 provided on one side of the linkage seat 6 is attached to the surface of the corresponding side of the trigger member 4, so that the linkage seat 6 is in surface contact with the trigger member 4. Since the trigger member 4 can only slide in one direction under the limit and cannot rotate, the linkage seat 6 is limited in the rotation direction through surface contact, so that it cannot rotate with the lock tongue 21 as the axis, thereby avoiding the linkage seat 6 from moving away from the top of the drive plate 41 due to rotation, ensuring the overlap of the linkage seat 6 and the drive plate 41, and ensuring that the trigger member 4 can manually drive the lock tongue 21 through the linkage seat 6.

[0049] In some embodiments, the inner walls of the lock housing 22 on both sides of the operating window 23 are provided with guide rails 25, and the guide rails 25 are assembled into the slide grooves provided in the trigger member 4. The guide rails 25 are embedded in the slide grooves to form a sealing structure on both sides of the operating window 23, so as to prevent water vapor from entering the lock housing through the operating window and contacting the electronic components such as the driving components and causing damage to them, so that the lock body can be installed in the storage space of the refrigerator and contact the cold air. Even if it can ensure long-term stable operation.

[0050] In some embodiments, the trigger member 4 has an operating panel 42, which is vertically connected to the driving panel 41. The operating panel 42 is attached to the surface of the lock housing 22 and is slidably installed on the guide rail 25 through a set slide groove. The shift block 43 set on the operating panel 42 is slidably installed in the operating window 23, and the operating panel 42 covers the operating window 23.

[0051] The trigger 4 is in surface contact with the lock housing 22 by setting the operating panel 42, which not only provides an installation position for the shift block 43 in the operating window 23, but also increases the limit and support of the lock housing 22 on the trigger 4 in the first direction by the surface contact with the lock housing 22. The trigger 4 can be driven to slide by the finger to shift the shift block 43. The operating panel 42 covers the operating window 23, thereby preventing the water vapor in the refrigerator from entering the lock housing 22 of the lock body 2 through the operating window 23, and preventing the water vapor from entering and damaging the electronic components inside the lock body 2.

[0052] In some embodiments, a support plate 44 is installed between the operating plate 42 and the driving plate 41, and the support plate 44 is vertically connected to both the operating plate 42 and the driving plate 41. The support plate 44 serves as a stiffening rib to reinforce the operating plate 42 to prevent it from deforming inward during manual operation due to its low strength, so that it maintains sliding contact with the inner wall of the lock housing 22, continuously closes the inner end of the operating window 23, and maintains a barrier effect against water vapor.

[0053] In some embodiments, there are two support plates 44 , one support plate 44 is attached to the inner wall of the lock housing 22 , and the other support plate 44 is attached to the first matching surface 61 of the linkage seat 6 .

[0054] The trigger member 4 is not only limited in the second direction by the two support plates 44, but also limited in the second direction on both sides by the inner wall of the lock housing 22 and the linkage seat 6 connected to the lock tongue 21, thereby improving its stability in the second direction and allowing it to slide smoothly under the guidance of the guide rail 25 without moving in the second direction.

[0055] In some embodiments, the linkage rod 62 provided on the linkage seat 6 extends above the driving plate 41 and contacts the upper surface thereof, and the linkage rod 62 is slidably installed in the guide groove 45 provided on the corresponding side support plate 44 .

[0056] The linkage seat 6 is overlapped with the driving plate 41 through the linkage rod 62. The guide groove 45 eliminates the blocking of the linkage rod 62 by the support plate 44, so that it extends to the top of the driving plate 41 and overlaps with it, and by guiding the linkage rod 62, the movement of the lock tongue 21 is smoother when it retracts and contracts. In addition, the linkage rod 62 is inserted into the guide groove 45, so that it can limit the linkage seat 6 in the rotation direction.

[0057] In some embodiments, one side of the lock housing 22 is open, so that the lock tongue 21, the driving element 5, the trigger 4 and other components are installed in the lock housing 22, and the open side of the lock housing 22 is closed by the installed side plate 27, so that the components are encapsulated in the lock housing 22. In order to ensure sealing, a sealing strip is installed between the side plate 27 and the lock housing 22.

[0058] The side plate 27 has an L-shaped cross-section, which is divided into a covering portion 271 and an assembly portion 272. The covering portion 271 is located on the side of the lock shell 22 away from the operating window 23. The assembly portion 272 extends into the lock shell 22 and is attached to the inner wall of the lock shell 22. One end of the assembly portion 27 presses the trigger member 4 on the inner wall of the lock shell 22 close to the operating window 23. A retaining edge 26 is vertically provided on the inner wall of the lock shell 22. The retaining edge 26 is located on the side of the operating window 23 away from the assembly portion 272. The trigger member 4 is vertically connected to a baffle 46, which is attached to the baffle 46. Two guide rails 25 are located between the assembly portion 272 and the retaining edge 26.

[0059] The lock shell 22 is closed by an L-shaped side plate 27, a part of which extends into the interior of the lock shell 22 and contacts its inner wall surface, having a wider contact surface, thereby better sealing the lock shell 22, and the extended part presses the trigger member 4, so that the trigger member 4 more tightly closes the operating window 23. At the same time, a retaining edge 26 is provided on the other side of the operating window 23 and a baffle 46 is also provided on the other side of the trigger member 4. The baffle 46 contacts the retaining edge 26 to form another sealing structure, thereby improving the sealing performance of the connection between the trigger member 4 and the lock shell 22 and preventing water vapor from entering due to the opening of the operating window 23.

[0060] In some embodiments, the linkage rod 62 is attached to the inner wall of the guide groove 45, so that the operating plate 42 is pressed against the inner wall of the corresponding lock housing 22. Since the linkage seat 6 is in surface contact with the trigger member 4 through the first mating surface 61 and cannot rotate, the linkage rod 62 maintains a fixed angular position in the circumferential direction, and the linkage rod 62 can support the trigger member 4 through the inner wall of the guide groove 45, thereby improving the stability of the trigger member 4 in the first direction.

[0061] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0062] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
