[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 6 As shown, an embodiment of the present invention provides an emergency lock structure, including a support frame 1, an emergency pull rod 2, a limiting rod 3, a stop assembly 4, and a plurality of first door locks 5 spaced apart on the support frame 1, each of the first door locks 5 being provided with a first unlocking part 51; The emergency pull rod 2 is provided with a plurality of first trigger parts 21 spaced apart. The emergency pull rod 2 is slidably mounted on the support frame 1. The first trigger parts 21 are used to press the first unlocking part 51 to unlock the first door lock 5. The support frame 1 is provided with a first limiting hole 11, and the limiting rod 3 is installed on the emergency pull rod 2 and slidably inserted into the first limiting hole 11; The stop assembly 4 includes a stop plate 41, a fastener 42, and a rotating shaft 43. The stop plate 41 is rotatably mounted on the support frame 1 via the rotating shaft 43. The support frame 1 is also provided with a fastening hole 12. The fastening hole 12 and the rotating shaft 43 are respectively located on opposite sides of the first limiting hole 11. The fastener 42 is mounted on the stop plate 41 and can be detachably inserted into the fastening hole 12. When the fastener 42 is inserted into the fastening hole 12, the stop plate 41 is used to limit and fix the limiting rod 3 in the first limiting hole 11.

[0021] The limiting rod 3, the fastener 42, and the rotating shaft 43 include, but are not limited to, screws and bolts, and the limiting hole is an elongated hole, a waist-shaped hole, etc. The number of the first trigger part 21 and the first door lock 5 can be set according to actual needs, and the number of the first trigger part 21 and the first door lock 5 is equal. Further, the first door lock 5 is an electromagnetic lock, an electronic lock, etc.; in the storage cabinet, each first door lock 5 corresponds to a first storage compartment, and the first door lock 5 is used to control the first cabinet door to lock the first storage compartment, and all the first storage compartments are arranged at intervals in the vertical direction, and the first door locks 5 are also arranged at intervals in the vertical direction.

[0022] In this utility model, during transportation, the fastener 42 is inserted into the fastening hole 12, and the stop plate 41 can partially block the first limiting hole 11, thereby limiting the limiting rod 3 in the first limiting hole 11 (the limiting rod 3 will not slide along the first limiting hole 11). The limiting rod 3 is fixedly connected to the emergency pull rod 2, thereby fixing the emergency pull rod 2 on the support frame 1. During transportation, the emergency pull rod 2 will not be misaligned, ensuring the stability of the emergency pull rod 2 installed on the support frame 1. When installing the emergency lock structure on-site, after the fastener 42 exits the fastening hole 12, the stop plate 41 rotates around the rotating shaft 43 until the stop plate 41 moves away from the first limiting hole 11. When the first door lock 5 malfunctions, the worker moves the emergency pull rod 2, and the limiting rod 3 slides in the first limiting hole 11. The first trigger part 21 of the emergency pull rod 2 will press the first unlocking part 51, thereby unlocking the first door lock 5. Since the emergency pull rod 2 is provided with multiple first trigger parts 21 spaced apart, each first trigger part 21 can unlock one first door lock 5, so the emergency pull rod 2 can unlock multiple first door locks 5 at once. In this utility model, the emergency lock structure is simple in structure, convenient to operate, low in cost, and ensures the positional accuracy of the emergency pull rod 2 during transportation.

[0023] In one embodiment, such as Figure 2 and Figure 6 As shown, the limiting rod 3 includes a screw 31 and an end 32 connected to the screw 31. The emergency pull rod 2 is provided with a threaded hole 22, and the screw 31 is threadedly connected to the threaded hole 22. The stop plate 41 is provided with a flap 412; when the fastener 42 is inserted into the fastening hole 12, the end 32 abuts against the flap 412.

[0024] Specifically, when the fastener 42 is inserted into the fastening hole 12, by rotating the fastener 42, the end 32 of the limiting rod 3 will press the flap 412 of the fastener 42, ensuring the clamping force between the limiting rod 3 and the stop plate 41; during the transportation of the emergency lock structure, the limiting rod 3 and the stop plate 41 are less likely to be displaced, further ensuring the positional accuracy of the emergency pull rod 2 installed on the support frame 1.

[0025] In one embodiment, such as Figure 1 As shown, the stop plate 41 has a flexible layer 411 on the side facing the support frame 1, and the flexible layer 411 abuts against the support frame 1.

[0026] The flexible layer 411 includes, but is not limited to, silicone sheets, foam cotton, etc., attached to the stop plate 41.

[0027] In this embodiment, the flexible layer 411 is designed such that, during the movement of the limiting rod 3 toward the emergency pull rod 2, the limiting rod 3 will squeeze the flexible layer 411 through the stop plate 41, further ensuring the clamping force between the limiting rod 3 and the stop plate 41.

[0028] In one embodiment, such as Figure 3 and Figure 4 As shown, the emergency lock structure also includes a plurality of second door locks (not shown in the figure) installed at intervals on the support frame 1, and the second door locks are provided with second unlocking parts; the first door lock 5 and the second door locks are respectively located on opposite sides of the emergency pull rod 2; The emergency pull rod 2 is provided with a plurality of second trigger parts 23 spaced apart, and the second trigger parts 23 are used to press the second unlocking part to unlock the second door lock.

[0029] The number of the second door lock and the second trigger part 23 can be set according to actual needs. Multiple first trigger parts 21 are spaced apart along the length of the emergency pull rod 2, and multiple second trigger parts 23 are also spaced apart along the length of the emergency pull rod 2. The first trigger parts 21 and the second trigger parts 23 are located on the left and right sides of the emergency pull rod 2, respectively. Correspondingly, the first door lock 5 and the second door lock are located on the left and right sides of the emergency pull rod 2, respectively. Further explanation: the second door lock is an electromagnetic lock, electronic lock, etc.; in the storage cabinet, each second door lock corresponds to a second storage compartment, and the second door lock is used to control the second cabinet door to lock the second storage compartment.

[0030] In this embodiment, moving the emergency lever 2 will unlock the first door lock 5 through the first trigger part 21 and unlock the second door lock through the second trigger part 23, thereby improving the integration of the emergency lock structure.

[0031] In one embodiment, such as Figure 4 As shown, the emergency pull rod 2 includes a base plate 24 and a first side plate 25 and a second side plate 26 connected to the two sides of the base plate 24. The first trigger part 21 and the second trigger part 23 are respectively disposed on opposite sides of the base plate 24. The first side plate 25 is provided with a plurality of first side holes 251 spaced apart, and the first trigger part 21 passes through the first side hole 251 one by one. The second side plate 26 is provided with a plurality of second side holes 261 spaced apart, and the second trigger part 23 passes through the second side holes 261 one by one.

[0032] The first side plate 25 and the second side plate 26 are parallel, and the first side plate 25 and the bottom plate 24 are parallel; the first side plate 25, the second side plate 26 and the bottom plate 24 are integrally formed parts.

[0033] In this embodiment, the emergency pull rod 2 includes a base plate 24 and a first side plate 25 and a second side plate 26 connected to opposite sides of the base plate 24. The emergency pull rod 2 has greater strength and rigidity, which extends the service life of the emergency lock structure.

[0034] In one embodiment, such as Figure 4 As shown, the first side plate 25 is provided with a through hole 252, and the second side plate 26 is provided with a threaded hole 22. One end of the limiting rod 3 passes through the first limiting hole 11 and the through hole 252 and is threadedly connected in the threaded hole 22.

[0035] The limiting rod 3 passes through the emergency pull rod 2, so that the limiting rod 3 can fix the emergency pull rod 2 on the support frame 1 through the stop plate 41, and ensure the positional accuracy of the emergency pull rod 2 installed on the support frame 1.

[0036] In one embodiment, such as Figure 5 and Figure 7 As shown, the emergency lock structure also includes an elastic element 7, a lever arm 8 with a paddle 81, and a third door lock 6 with a third unlocking part 61, the third door lock 6 being mounted on the support frame 1; The lever arm 8 is provided with a mounting part 82 and an execution part 83 at opposite ends. The mounting part 82 is rotatably mounted on the support frame 1. The paddle 81 is located between the mounting part 82 and the execution part 83. The elastic element 7 is connected to the lever arm 8 and the support frame 1 at opposite ends. The actuator 83 is used to drive the lever arm 8 to rotate around the first direction, so that the paddle 81 presses the third unlocking part 61 to unlock the third door lock 6; The elastic element 7 is used to drive the lever arm 8 to rotate around the second direction, so that the paddle 81 moves away from the third unlocking part 61; wherein the first direction is opposite to the second direction.

[0037] The elastic element 7 includes, but is not limited to, springs; of the first direction and the second direction, one is clockwise and the other is counterclockwise; of the mounting part 82 and the actuating part 83, one is located at the left end of the lever arm 8 and the other is located at the right end of the lever arm 8; the third door lock 6 includes, but is not limited to, mechanical locks, electric locks, electromagnetic locks, etc. Preferably, the lever arm 8 is a flat plate structure.

[0038] In this embodiment, an emergency lock is configured with the third door lock 6. When the third door lock 6 malfunctions, the operator inserts the key into the lock hole of the emergency lock and drives the bolt to rotate. The bolt abuts against the actuator 83 and drives the lever arm 8 to rotate around the first direction until the paddle 81 on the lever arm 8 presses the third unlocking part 61 of the third door lock 6, and the third door lock 6 is in the unlocked state. The elastic element 7 can drive the lever arm 8 to rotate around the second direction, and the paddle 81 moves away from the third unlocking part 61 of the third door lock 6. Under normal conditions, the lever arm 8 will not press the third unlocking part 61 of the third door lock 6. The lever 81 is located between the mounting part 82 and the actuating part 83, so that the lever 81 and the actuating part 83 are on the same side of the mounting part 82. The lever arm length between the lever 81 and the mounting part 82 is less than the lever arm length between the unlocking part and the mounting part 82. According to the lever principle, a small rotational force can be applied to the emergency lock to drive the lever arm 8 to rotate, which improves the convenience of unlocking the third door lock 6 by the lever arm 8. In addition, the lever arm 8 is shorter, and the emergency lock structure has fewer parts, which reduces the cost and space occupied by the emergency lock structure.

[0039] To further explain, the locker is equipped with a main compartment corresponding to the third door lock 6, and the third door lock 6 can control the closing of the main compartment.

[0040] In one embodiment, such as Figure 7 and Figure 8 As shown, the lever arm 8 is also provided with a second limiting hole 84, which is located between the mounting part 82 and the execution part 83; The emergency lock structure also includes a limiting member 9 installed on the support frame 1, which is slidably inserted into the second limiting hole 84.

[0041] The second limiting hole 84 is an elongated hole or a waist-shaped hole. During the rotation of the lever arm 8, the limiting member 9 slides in the second limiting hole 84. The limiting member 9 includes, but is not limited to, screws, bolts, etc.

[0042] In this embodiment, the second limiting hole 84 can limit the rotation angle of the lever arm 8 through the limiting member 9, so as to avoid the problem of the lever arm 8 having an excessive rotation angle.

[0043] In one embodiment, such as Figure 7 and Figure 8 As shown, the lever arm 8 is also provided with a connecting part 85, and the end of the elastic member 7 away from the support frame 1 is connected to the connecting part 85; the distance between the paddle 81 and the mounting part 82 is less than the distance between the connecting part 85 and the mounting part 82.

[0044] The paddle 81 is disposed on the upper side of the lever arm 8, and the connecting part 85 is disposed on the lower side of the lever arm 8. The connecting part 85 may be provided with a connecting hole for connecting the elastic element 7.

[0045] In this embodiment, the distance between the paddle 81 and the mounting part 82 is smaller than the distance between the connecting part 85 and the mounting part 82, so that the elastic element 7 can drive the lever arm 8 to rotate around the second direction with a small elastic pulling force.

[0046] Another embodiment of this utility model provides a storage cabinet, including the above-described emergency lock structure.

[0047] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
