Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.
[0041] 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.
[0042] like Figures 1 to 3 As shown, in an illustrative embodiment of the high-security refrigerator of the utility model, the high-security 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. The lock hook 31 mounted on the cabinet door 3 has a plug-in slot 32, and the lock tongue 21 is inserted into the plug-in slot 32, so that the lock hook 31 can be limited, so that the cabinet door 3 cannot be opened and remains in a closed state; the lock tongue 21 is pulled out of the plug-in slot 32, so that the limit on the lock hook 32 can be eliminated, and the cabinet door 3 can be unlocked so that it can be opened.
[0043] A driving member 4 is slidably mounted in the lock housing 22 of the lock body 2, and the driving member 4 is connected to the lock tongue 21. A trigger member 5 is mounted on the outer side of the cabinet body 1, and the trigger member 5 is connected to the driving member 4 through a lock wire 6. When the trigger member 5 is manually operated, the trigger member 5 pulls the driving member 4 through the lock wire 6, so that the driving member 4 pulls the lock tongue 21 out of the lock hole on the cabinet door 3 or the plug-in slot 32 of the lock hook 31 installed on the cabinet door 3, thereby releasing the lock of the cabinet door 3.
[0044] When the manual operation is achieved by pulling the trigger member 5, the pulled trigger member 5 pulls the driving member 4 through the locking wire 6; when the manual operation is achieved by rotating or swinging the trigger member 5, the trigger member 5 has a rocker arm 82 or a capstan, the swinging rocker arm 82 directly pulls the locking wire 6, and the rotating capstan reels the locking wire 6, so that the locking wire 6 pulls the driving member 4.
[0045] In the above-mentioned illustrative embodiment, a trigger member 5 is arranged on the outer side of the cabinet body 1 of the high-security refrigerator, so that when the door lock is damaged and the cabinet door 3 cannot be opened, the trigger member 5 is manually operated to make the driving member 4 move therewith, and then the driving member 4 pulls the lock tongue 21 out of the lock hole on the cabinet door 3 or the plug-in slot 32 of the lock hook 31, thereby eliminating the lock on the cabinet door 3 and manually unlocking the door lock, which is convenient for opening the refrigerator for maintenance after the door lock is damaged, and can also help children escape in time when they are accidentally locked in the refrigerator, eliminating the corresponding safety hazards, improving the safety of the refrigerator during use, and solving the problem that it is difficult to open the door lock from the outside when the lock of the current smart refrigerator door 3 is damaged, resulting in maintenance difficulties and even safety threats.
[0046] In order to allow the lock wire 6 to pass through the lock body 2 and thus connect to the trigger member 5, a wire outlet hole 25 is provided at one end of the lock shell 22 of the lock body 2 away from the lock tongue 21. After one end of the lock wire 6 is fixedly connected to the driving member 4, the other end extends out through the wire outlet hole 25 and connects to the trigger member 5.
[0047] When the door lock opens or locks the cabinet door normally, in order to drive the lock tongue 21, as shown in FIG. Figure 8As shown, a drive element 7 is installed in the lock housing 22 of the lock body 2, and the drive element 7 has a valve body 71, and an electromagnet is installed in the valve body 71. The lock tongue 21 is slidably installed in the through hole 23 set in the lock housing 22, and the electromagnetic shaft 72 fixedly installed at its inner end is slidably installed in the valve body 71, so that the electromagnet drives the electromagnetic shaft 72 to move through the electromagnetic force, thereby realizing the extension and contraction of the lock tongue 21. The electromagnetic drive method enables the electromagnetic shaft 72 to pass through the valve body 71, so that it is connected to the driving member 4 on one side of the drive element 7 as a part of the lock tongue 21, so as to realize the connection between the lock tongue 21 and the driving member 4.
[0048] 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 28 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.
[0049] like Figure 4 As shown, one side of the lock housing 22 is open, so that the lock tongue 21, the driving element 7, the driving member 4 and other parts of the lock body 2 can be installed therein, and the lock housing 22 is closed on its open side by a side plate 26 installed by bolts, so that the parts are encapsulated in the lock housing 22.
[0050] In some embodiments, the trigger member 5 is a T-shaped lock 8 installed on the cabinet 1, and the T-shaped lock 8 has a swing rod 82 that can rotate with the lock cylinder 81, and the swing rod 82 is fixedly connected to the lock wire 6. Figures 9 and 10As shown, the lock cylinder 81 of the T-type lock 8 is inserted into the mounting hole 84 of its housing 83, and the external lock tongue 85 extending from the lock cylinder 81 is inserted into the external lock hole 86 on the inner wall of the mounting hole 84. When the key is not inserted, the lock cylinder 81 of the T-type lock 8 cannot rotate due to being locked. After the key is inserted into the keyhole, the key can be rotated to make the lock cylinder 81 pull the external lock tongue 85 out of the external lock hole 86, eliminating the limit of the lock cylinder 81 extending outward or manually pulled out under the action of the installed spring. Since the lock cylinder 81 is T-shaped in shape and its outer end is a handle structure, the lock cylinder 81 can be manually rotated, and the swing rod 82 fixedly connected to the lock cylinder 81 rotates accordingly, thereby pulling the lock wire 6 connected thereto, and then pulling the driving member 4 through the lock wire 6. After the manual unlocking of the refrigerator is completed, the extended lock cylinder 81 is pushed back, and the external lock tongue 85 is stuck into the external lock hole 86 on the inner wall of the mounting hole 84, completing the locking of the T-type lock 8. The T-lock 8 is a mechanical lock that is opened and closed by a key. In the prior art, it is generally installed on the cabinet door 3. When the cabinet door 3 is closed, its rocker bar 82 is rotated and extended to the rear side of the edge of the cabinet opening, so that the edge of the cabinet opening blocks the rocker bar 82 from moving forward, thereby locking the cabinet door 3 in a closed state. In the present application, it is used as a driving component for pulling the lock wire 6 to realize the movement of the driving member 4, and it itself has an anti-theft performance that can only be operated by a key. While realizing emergency unlocking outside the refrigerator, it prevents the trigger member 5 from being maliciously operated to cause the cabinet door 3 to be unlocked and the goods in the refrigerator to be lost.
[0051] The T-lock 8 can be replaced by other mechanical locks that can only be activated after the key is inserted, and the component connecting the lock wire 6 can be a capstan, which retracts and extends the lock wire 6 as the lock cylinder 81 rotates; the component connecting the lock wire 6 can also be a telescopic part driven by the lock cylinder 81, that is, the lock tongue of the mechanical lock is used as a telescopic part. When the key is inserted and twisted, the lock tongue is retracted into the lock body, thereby pulling the connected lock wire 6.
[0052] In some embodiments, Figures 5 to 7 As shown, the driving member 4 has a driving plate 41 , and a linkage seat 9 is fixedly mounted on the locking tongue 21 , and the linkage seat 9 is mounted on the upper side of the driving plate 41 .
[0053] The driving member 4 falls and rests on a structure or installed component provided in the lock housing 22. When the trigger member 5 is manually operated, the pulled-up driving member 4 pushes the linkage seat 9 through the driving plate 41, pulls up the lock tongue 21, and makes it come out of the lock hole or the plug-in slot 32, thereby eliminating the lock on the cabinet door 3 and realizing manual unlocking of the cabinet door 3.
[0054] When the driving element 7 drives the lock tongue 21 to extend and lock the cabinet door 3, the linkage seat 9 is pressed on the driving plate 41; when the driving element 7 drives the lock tongue 21 to pull up and release the lock of the cabinet door 3, the linkage seat 9 rises accordingly, breaks away from the contact with the driving plate 41, and rises to the space above it. The driving member 4 remains stationary, avoiding accelerated wear of the driving member 4 due to frequent sliding due to continuous movement with the lock tongue 21, thereby improving the service life of the driving member 4.
[0055] Since the trigger member 5 is far away from the driving member 4 and the two are connected by a long locking wire 6, if the trigger member 5 is not manually operated and remains stationary, and at this time, if the driving member 4 rises with the lock tongue 21, it will push the locking wire 6, and the locking wire 6 may be unable to smoothly pass through the wire outlet hole 25 and stacked inside the lock shell 22. Even if it extends out of the lock shell 22 through the wire outlet hole 25, since the other end of the locking wire 6 remains stationary with the trigger member 5, the locking wire 6 will still be stacked in the cabinet 1 outside the lock shell 22. The stacked locking wires 6 are easy to be entangled with each other, and cannot be fully unfolded when the driving member 4 is reset, causing the driving member 4 to be unable to reset to the initial position and be suspended in the air. The suspended driving member 4 will pull up the lock tongue 21 so that it cannot be fully inserted into the lock hole or the plug-in slot 32, eventually causing the door lock to be locked loosely. The drive member 4 is overlapped so that when the lock tongue 21 rises automatically, it does not move with it, which can prevent the lock wire 6 from being entangled when the trigger member 5 is not manually operated, and prevent the drive member 4 from being suspended in the air, thereby ensuring that the door lock can fall to a fully plugged and locked state.
[0056] In some embodiments, one side of the driving member 4 is slidably mounted on a guide rail 24 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 driving member 4 is pressed on the guide rail 24 on the other side, and the driving member 4 is limited in a first direction. And due to the cooperation between the driving member 4 and the guide rail 24, the guide rail 24 limits the driving member 4 in a second direction perpendicular to the first direction. The driving 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 24.
[0057] A first mating surface 91 provided on one side of the linkage seat 9 is attached to the surface of the corresponding side of the driving member 4, so that the linkage seat 9 is in surface contact with the driving member 4. Since the driving member 4 can only slide in one direction under the limit and cannot rotate, the linkage seat 9 is limited in the rotation direction through surface contact, so that it cannot rotate around the lock tongue 21 as the axis, thereby avoiding the linkage seat 9 from moving away from the top of the driving plate 41 due to rotation, ensuring the overlap of the linkage seat 9 and the driving plate 41, and ensuring that the driving member 4 can manually drive the lock tongue 21 through the linkage seat 9.
[0058] In some embodiments, the driving member 4 has an assembly plate 42, which is vertically connected to the driving plate 41. The assembly plate 42 is attached to the surface of the lock housing 22 and is slidably installed on the guide rail 24 through a set guide groove. A support plate 43 is installed between the assembly plate and the driving plate 41, and the support plate 43 is vertically connected to both the assembly plate and the driving plate 41.
[0059] The drive member 4 is in surface contact with the lock housing 22 by setting the assembly plate 42, so as to increase the limit and support of the lock housing 22 on the drive member 4 in the first direction. The support plate 43 is used as a stiffening rib to reinforce the drive member 4, so as to prevent it from being deformed under the pulling of the lock wire 6 due to its low strength, so as to make it move smoothly and drive the lock tongue 21 to be pulled out in time.
[0060] In some embodiments, there are two support plates 43 , one support plate 43 is attached to the inner wall of the lock housing 22 , and the other support plate 43 is attached to the first matching surface 91 of the linkage seat 9 .
[0061] The two support plates 43 not only further strengthen the structure of the driving member 4, but also limit the trigger member 5 in the second direction not only by the guide rail 24, but also by the inner wall of the lock shell 22 and the linkage seat 9 connected to the lock tongue 21 on both sides to limit the second direction, thereby improving its stability in the second direction and allowing it to slide smoothly under the guidance of the guide rail 24 without moving in the second direction.
[0062] In some embodiments, the linkage rod 92 provided on the linkage seat 9 extends above the driving plate 41 and contacts its upper surface, and the linkage rod 92 is slidably installed in the guide groove 44 provided on the support plate 43 on the corresponding side.
[0063] The linkage seat 9 is overlapped with the driving plate 41 through the linkage rod 92. The guide groove 44 eliminates the blocking of the linkage rod 92 by the support plate 43, so that it extends to the top of the driving plate 41 and overlaps with it, and by guiding the linkage rod 92, the movement of the lock tongue 21 is smoother when it retracts and contracts. In addition, the linkage rod 92 is inserted into the guide groove 44, so that it can limit the linkage seat 9 in the rotation direction.
[0064] The linkage rod 92 is attached to the inner wall of the guide groove 44, so that the assembly plate 42 is pressed against the inner wall of the lock housing 22 on the corresponding side. Since the linkage seat 9 is in surface contact with the driving member 4 through the first mating surface 91 and cannot rotate, the linkage rod 92 maintains a fixed angular position in the circumferential direction, and the linkage rod 92 can support the driving member 4 through the inner wall of the guide groove 44, thereby improving the stability of the driving member 4 in the first direction.
[0065] In some embodiments, a rib 27 is vertically disposed on the inner wall of the lock housing 22, and the rib 27 and the first mating surface 91 are both attached to the same surface of the driving member 4, so that the rib 27 presses the driving member 4 in the second direction, thereby improving the stability of the driving member 4 when sliding. The driving member 4 is vertically connected to a baffle 45, and the baffle 45 is attached to the rib 27, so that the lock housing 22 increases the support for the driving member 4 in the first direction through the contact between the rib 27 and the baffle 45, thereby improving the guiding effect of the lock housing 22 and the guide rail 25 in the lock housing 22 on the driving member 4.
[0066] In some embodiments, the trigger member 5 is a handle, which is located in a storage compartment 11 provided on the outer wall of the cabinet 1 , and a hatch 12 is installed on the hatch of the storage compartment 11 .
[0067] The lock wire 6 extends into the storage compartment 11 and is connected to the handle as the trigger member 5 in the storage compartment. When the handle is pulled outward, the driving member 4 can be pulled by the lock wire 6 to pull out the lock tongue 21. The compartment door 12 closes the storage compartment 11, thereby hiding the handle in the storage compartment 11 to prevent it from being directly exposed to the outside, thereby reducing the risk of it being maliciously pulled to open the cabinet door 3 and causing the goods to be lost.
[0068] In order to reduce the probability of the storage compartment 11 and the door 12 being discovered, they can be arranged on the side of the refrigerator to avoid facing the customers in front of it. In addition, when the refrigerator is hidden, it is placed in a hole opened in the wall or furniture, and the storage compartment 11 and the door 12 located on the side will be blocked by the hole, reducing the probability of malicious unlocking.
[0069] In some embodiments, a key mechanical lock is installed between the door 12 and the cabinet 1, and the key mechanical lock locks the door 12. When a child is trapped or the door lock is damaged, the door 12 can be opened with a key, and the handle can be operated to manually unlock. When no abnormality occurs, the handle is locked in the storage compartment 11 to prevent malicious operation of the handle to open the door 3 and cause the loss of goods. Since the trigger 5 has anti-theft measures, it can be set at the front of the refrigerator, in a position that is easier to observe and operate, so that manual unlocking can be performed more promptly in unexpected situations such as children being trapped.
[0070] 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.
[0071] 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.
