[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] like Figures 1 to 3 As shown, an emergency locking device provided in one embodiment of the present invention includes a support plate 1, an emergency unlocking component 2, and a door lock 3 with an unlocking part 31, wherein the door lock 3 is installed on the support plate 1; The emergency unlocking component 2 includes an elastic element 21, a lever arm 22 with a paddle 221, and an emergency lock 23 with a locking tongue 231. The lever arm 22 has a mounting part 222 and an actuating part 223 at opposite ends. The mounting part 222 is rotatably mounted on the support plate 1. The paddle 221 is located between the mounting part 222 and the actuating part 223. The elastic element 21 is connected to the lever arm 22 and the support plate 1 at opposite ends. The latch 31 of the emergency lock 23 is used to drive the lever arm 22 to rotate around the first direction through the actuator 223, so that the paddle 221 presses the unlocking part 31 to unlock the door lock 3; The elastic element 21 is used to drive the lever arm 22 to rotate around the second direction, so that the paddle 221 moves away from the unlocking part 31; wherein the first direction is opposite to the second direction.
[0021] The elastic element 21 includes, but is not limited to, a spring; of the first direction and the second direction, one is clockwise and the other is counterclockwise; of the mounting part 222 and the actuating part 223, one is located at the left end of the lever arm 22 and the other is located at the right end of the lever arm 22; the door lock 3 includes, but is not limited to, a mechanical lock, an electric lock, an electromagnetic lock, etc. Preferably, the lever arm 22 is a flat plate structure.
[0022] In this utility model, the emergency unlocking component 2 includes an elastic element 21, a lever arm 22 with a paddle 221, and an emergency lock 23 with a latch 231. The lever arm 22 has a mounting portion 222 and an actuating portion 223 at opposite ends. The mounting portion 222 is rotatably mounted on the support plate 1. The paddle 221 is located between the mounting portion 222 and the actuating portion 223. The elastic element 21 is connected to the lever arm 22 and the support plate 1 at opposite ends. When the door lock 3 malfunctions, the operator will unlock the door. The key is inserted into the lock hole of the emergency lock 23 and drives the bolt 231 to rotate. The bolt 231 abuts against the actuator 223 and drives the lever arm 22 to rotate around the first direction until the paddle 221 on the lever arm 22 presses the unlocking part 31 of the door lock 3, and the door lock 3 is in the unlocked state. The elastic element 21 can drive the lever arm 22 to rotate around the second direction, and the paddle 221 moves away from the unlocking part 31 of the door lock 3. Under normal conditions, the lever arm 22 will not press the unlocking part 31 of the door lock 3. The lever 221 is located between the mounting part 222 and the actuating part 223, so that the lever 221 and the actuating part 223 are on the same side of the mounting part 222. The lever arm length between the lever 221 and the mounting part 222 is less than the lever arm length between the unlocking part 31 and the mounting part 222. According to the lever principle, a small rotational force can be applied to the emergency lock 23 to drive the lever arm 22 to rotate, which improves the ease of operation of the emergency lock device. In addition, the lever arm 22 is relatively short, and the emergency lock device has fewer parts, reducing the cost and space occupied by the emergency lock device.
[0023] In one embodiment, such as Figures 1 to 3 As shown, the lever arm 22 is also provided with a limiting hole 224, which is located between the mounting part 222 and the execution part 223; The emergency unlocking component 2 also includes a limiting member 24 installed on the support plate 1, the limiting member 24 being slidably inserted into the limiting hole 224.
[0024] The limiting hole 224 is an elongated hole. During the rotation of the lever arm 22, the limiting member 24 slides in the limiting hole 224. The limiting member 24 includes, but is not limited to, screws, bolts, etc.
[0025] In this embodiment, the limiting hole 224 can limit the rotation angle of the lever arm 22 through the limiting member 24, so as to avoid the problem of the lever arm 22 rotating too much.
[0026] In one embodiment, such as Figures 1 to 3 As shown, the emergency unlocking component 2 also includes a rotating shaft 25, a first pad 26 with a first through hole, and a second pad 27 with a second through hole; the mounting part 222 is provided with a shaft hole 226, one end of the rotating shaft 25 passes through the shaft hole 226 and the first through hole and is mounted on the support plate 1, and one end of the limiting member 24 passes through the limiting hole 224 and the second through hole and is mounted on the support plate 1.
[0027] The rotating shaft 25 includes, but is not limited to, screws and bolts, and the first pad 26 and the second pad 27 include, but are not limited to, gaskets and copper sleeves.
[0028] In this embodiment, the first pad 26 and the second pad 27 are both disposed between the lever arm 22 and the support plate 1, so that there is a certain gap between the lever arm 22 and the support plate 1, which avoids the lever arm 22 from generating a large friction force due to contact with the support plate 1, and further ensures the smoothness of the rotation of the lever arm 22.
[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the lever arm 22 is also provided with a connecting part 225, and the end of the elastic member 21 away from the support plate 1 is connected to the connecting part 225; the distance between the paddle 221 and the mounting part 222 is less than the distance between the connecting part 225 and the mounting part 222.
[0030] The paddle 221 is disposed on the upper side of the lever arm 22, and the connecting part 225 is disposed on the lower side of the lever arm 22. The connecting part 225 may be provided with a connecting hole for connecting the elastic element 21.
[0031] In this embodiment, the distance between the paddle 221 and the mounting portion 222 is less than the distance between the connecting portion 225 and the mounting portion 222, so that the elastic element 21 can drive the lever arm 22 to rotate around the second direction with a small elastic pulling force.
[0032] In one embodiment, such as Figure 1As shown, the door lock 3 is an electronically controlled lock.
[0033] When the door lock 3 is functioning properly, the user can control its opening and closing by entering a password or remotely. When the door lock 3 malfunctions, the user can control it to be in the open state using the emergency unlocking component 2.
[0034] like Figure 4 and Figure 5 As shown, another embodiment of this utility model also provides a storage cabinet, including a cabinet body 4, a cabinet door 5 and the aforementioned emergency locking device. The cabinet body 4 is provided with a storage space 41, and the cabinet door 5 is installed on the cabinet body 4 and used to open or close the storage space 41. The support plate 1 is installed on the cabinet body 4, and the door lock 3 is installed on the cabinet door 5.
[0035] The cabinet door 5 can be rotatably mounted on the cabinet body 4, and the door lock 3 can control the cabinet door 5 to be in the state of opening or closing the storage space 41.
[0036] In one embodiment, such as Figures 4 to 6 As shown, the storage cabinet also includes a first latch 51 installed on the cabinet door 5, and the door lock 3 is also provided with a second latch 32 adapted to the first latch 51; When the first latch 51 and the second latch 32 are locked together, the cabinet door 5 closes the storage space 41. When the first latch 51 disengages from the second latch 32, the cabinet door 5 opens the storage space 41.
[0037] Specifically, under normal conditions, when the cabinet door 5 is closed, the first latch 51 and the second latch 32 engage, thus closing the storage space 41. When the user enters a password or performs other operations, the second latch 32 disengages from the first latch 51, allowing the storage space 41 to open through the cabinet door 5 interface. When the door lock 3 is malfunctioning, the user presses the unlocking part 31 of the door lock 3 using the emergency unlocking component 2, disengaging the second latch 32 from the first latch 51 and opening the storage space 41 through the cabinet door 5 interface.
[0038] In one embodiment, such as Figure 1 As shown, the cabinet 4 is also provided with a storage space and a partition 43. The partition 43 is located between the storage space 42 and the storage space 41. The partition 43 is provided with an installation port 431 that connects the storage space 42 and the storage space 41. The support plate 1 is installed on the partition 43 and is used to block the installation port 431. The mounting part 222, the door lock 3, and the elastic element 21 are all located in the accommodating space 42.
[0039] When the support plate 1 is installed in the mounting port 431, the support plate 1 is flush with the partition 43, so that the support plate 1 and the partition 43 can separate the storage space 41 and the accommodating space 42.
[0040] In this embodiment, the elastic element 21, the door lock 3, and most of the lever arm 22 are located in the accommodating space 42. The emergency locking device is not located in the storage space 41, so the storage space 41 can hold more items, and the emergency locking device will not block items from entering or leaving the storage space 41.
[0041] In one embodiment, such as Figure 1 , Figure 4 as well as Figure 6 As shown, the support plate 1 includes a panel 11 and a flip plate 12 and a bending plate 13 disposed on opposite sides of the panel 11. The flip plate 12 is provided with a first side hole 121 and a second side hole 122 spaced apart. The mounting part 222 is rotatably mounted on the panel 11. The door lock 3 is mounted on the panel 11. The end of the elastic member 21 away from the door lock 3 is connected to the panel 11. The lever arm 22 passes through the first side hole 121, and the first locking part 51 extends into the second side hole 122 and locks with the second locking part 32. The bending plate 13 is installed on the partition 43, the panel 11 is located in the mounting opening 431 and blocks the mounting opening 431, and the partition 43 is flush with the panel 11.
[0042] In this configuration, the flip plate 12 is perpendicular to the panel 11, and the bent plate 13 is attached to the side of the partition 43 facing the accommodating space 42.
[0043] In this embodiment, the bending plate 13 is installed on the partition 43, and the panel 11 is located in the mounting opening 431 and blocks the mounting opening 431. Thus, the side of the partition 43 and the panel 11 facing the storage space 41 is a smooth plane, avoiding gaps in the inner wall of the storage space 41. Furthermore, the disassembly and assembly of the support plate 1 and the partition 43 are convenient.
[0044] In one embodiment, such as Figure 4 As shown, the emergency locking device also includes a guide ramp 52 installed at the bottom of the cabinet door 5; When the cabinet door 5 closes the storage space 41, the guide plate 52 is used to block the gap between the bottom of the cabinet door 5 and the cabinet body 4.
[0045] In this embodiment, the guide plate 52 is inclined downwards and is used to block the gap between the bottom of the cabinet door 5 and the cabinet body 4. Thus, the guide plate 52 can prevent rainwater from entering the storage space 41 from the bottom of the cabinet door 5, thereby improving the waterproof performance of the storage cabinet.
[0046] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
