[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0028] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the outline of the corresponding parts themselves; the directional words used, such as "top" and "bottom", are defined based on the usage habits of the auxiliary locking device provided by the present disclosure. Specifically, reference can be made to Figure 3 In the direction of the drawing shown, the side indicated by the Z arrow is the top, and the opposite side is the bottom. The terms used in this disclosure, such as "first" and "second", are used to distinguish one element from another element and do not have order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements.

[0029] Reference Figure 1-Figure 3The present disclosure provides an auxiliary locking device for a cabinet, wherein the cabinet may include a cabinet door and a mechanical lock for locking the cabinet door, and the mechanical lock may include a lock box 30 fixed on the surface of the cabinet door 40 and a lock hole 31 arranged on the surface of the lock box 30. The auxiliary locking device may be used to assist the mechanical lock in locking the cabinet door 40, and the auxiliary locking device may include a cover body 10 and a mounting plate 21. The cover body 10 may be used to cover the lock box 30 corresponding to the lock hole 31, and the cover body 10 may be docked with the cabinet door 40 to isolate the lock hole 31 from the outside, thereby preventing the lock hole 31 from being illegally opened, thereby improving the safety of the cabinet. The mounting plate 21 can be connected to the edge of the cover body 10 for docking with the cabinet door 40, and the side of the mounting plate 21 can be arranged in contact with the surface of the cabinet door 40. The mounting plate 21 can be detachably connected to the cabinet door 40. While the cover body 10 can be installed on the cabinet door 40, the connection between the mounting plate 21 and the cabinet door 40 has strong reliability, thereby effectively preventing the cover body 10 from falling off due to external force collision, and effectively improving the safety and reliability of the auxiliary locking device during use. Through the detachable connection between the mounting plate 21 and the cabinet door 40, when the cabinet door 40 has a need to be opened, it is convenient for the auxiliary locking device to release the lock on the cabinet door 40, and it is also convenient to maintain and replace the auxiliary locking device.

[0030] Through the above technical solution, the cover body 10 is detachably mounted on the cabinet door 40 corresponding to the lock box 30 through the mounting plate 21, so as to be used in conjunction with the existing mechanical lock, thereby further locking the cabinet door 40 to enhance the safety of the cabinet, and while being able to prevent the cabinet door 40 from being easily opened by unauthorized personnel, it also avoids the lock hole from being exposed to the outside for a long time, greatly reducing the vulnerability of the lock hole and ensuring the normal use of the mechanical lock. In addition, the auxiliary locking device provided by the present disclosure has a simple and compact structure, does not require large-scale modification of the cabinet, and greatly reduces the production and modification costs.

[0031] Reference Figure 1-Figure 3 The cover body 10 may include a cover body 11. The cover body 11 may be constructed as a cover body with a lateral opening 111 and a hollow interior. The lateral opening 111 may be arranged through along the X direction. On the one hand, the air permeability of the cover body 11 may be increased to avoid local overheating at the mechanical lock. On the other hand, the lateral opening 111 may be used as an observation hole, which is convenient for the staff to check the status of the lock hole 31 at any time to ensure that the staff can open the auxiliary locking device for the first time to handle the accident when an accident occurs.

[0032] Reference Figure 1-Figure 3The cross section of the cover body 11 can be constructed as a U-shaped structure to ensure the structural strength of the cover body 11 and improve the stability of the cover body 11. The two first side walls 112 located on the opening side of the U-shaped structure can both be vertically abutted against the surface of the cabinet door 40 along the Y direction, or the two first side walls 112 can also be vertically abutted against the surface of the lock box 30 along the Y direction, or, as Figure 3 As shown, one of the two first side walls 112 abuts against the surface of the cabinet door 40 along the Y direction, and the other of the two first side walls 112 abuts against the surface of the lock box 30 along the Y direction. In this way, not only the process of installing the auxiliary locking device corresponding to the mechanical lock is simplified and the installation efficiency is improved, but also the reliability of the installation position of the auxiliary locking device is ensured. The second side wall 113 located on the closed side of the U-shaped structure can be connected between the two first side walls 112, and the second side wall 113 can cover the lock hole 31 along the Y direction. The second side wall 113 can be spaced from the lock hole 31 along the Y direction, and the spacing between the second side wall 113 and the lock hole 31 can be formed as the lateral opening 111 mentioned above, so as to facilitate the staff to observe the lock hole 31 from the X direction. Through the spacing between the second side wall 113 and the lock hole 31, mutual friction between the auxiliary locking device and the lock hole 31 can be avoided, and wear of the auxiliary locking device on the lock hole 31 can be avoided.

[0033] Reference Figure 1-Figure 3 The auxiliary locking device may further include a padlock (not shown in the figure), which may include a strip-shaped locking hoop and a lock body. The cover body 11 may further include two locking noses 114 symmetrically arranged on the two first side walls 112 and a first through hole 115 opened on the second side wall 113 at a position corresponding to the locking hole 31, wherein the strip-shaped locking hoop sequentially passes through the two locking noses 114 and is detachably connected to the lock body. Figure 3 Since the second side wall 113 is located between the two first side walls 112, and the opening of the U-shaped structure faces the lock box 30, when the padlock is in a locked state, the strip lock hoop is connected to the lock body, and the strip lock hoop is in a state of sequentially penetrating the two lock noses 114. At this time, the strip lock hoop is located between the two sides of the second side wall 113 and the lock box 30 that are close to each other, so as to effectively separate the first through hole 115 and the lock hole 31, thereby preventing the staff from unlocking the lock hole 31 through the first through hole 115, so that the cabinet door 40 is in a locked state. According to the embodiment provided by the present disclosure, when the cabinet door 40 has a need to be opened, the strip lock hoop can be separated from the lock body first, and the strip lock hoop can be pulled out from the two lock noses 114, so as to cancel the separation between the first through hole 115 and the lock hole 31, so that the staff can unlock the lock hole 31 through the first through hole 115 without opening the cover body 10. Of course, when the cabinet door 40 needs to be closed after being opened, the first through hole 115 can also be used to lock the lock hole 31. The specific operation process is opposite to the operation sequence of opening the cabinet door 40, and will not be repeated here.

[0034] Reference Figure 2 and Figure 3 The cover body 10 may further include an ear plate 12, which may be bent and connected to the edge of the lateral opening 111. The length direction of the lock box 30 may extend along the Z direction. When the cross-section of the lateral opening 111 is configured as the U-shaped structure mentioned above, the two first side walls 112 may be spaced apart along the Z direction, one of the two second side walls 112 may be disposed at the top of the lock box 30 and abut against the surface of the cabinet door 40 along the Y direction, and the other of the two first side walls 112 may abut against the surface of the lock box 30 along the Y direction. On the surface, one end of the ear plate 12 can be vertically connected to the first side wall 112 abutting on the surface of the lock box 30, and the other end of the ear plate 12 can extend along the Z direction toward the bottom end of the lock box 30 to extend out of the lock box 30, and the portion of the ear plate 12 extending out of the lock box 30 can be bent along the Y direction and abut on the cabinet door 40, which can avoid the installation of the lock body and can laterally surround the lock box 30 to protect the surface of the lock box 30 to a certain extent, thereby improving the safety of the lock box 30. The ear plate 12 can fit the surface of the lock box 30 to reduce the gap between the cover body 10 and the lock box 30, effectively preventing external objects from entering between the lock box 30 and the cover body 10 through the gap. On the other hand, it can also effectively increase the contact area between the cover body 10 and the lock box 30, improve the integrity between the auxiliary locking device and the mechanical lock, and reduce the space occupied.

[0035] Further, refer to Figure 3 In the embodiment provided in the present disclosure, the outer contour area of ​​the ear plate 12 is not less than the outer contour area of ​​the lock box 30 directly opposite the ear plate 12 along the Y direction, so as to ensure the coverage area of ​​the ear plate 12 on the surface of the lock box 30 and improve the protection effect on the lock box 30.

[0036] Reference Figure 1-Figure 2The auxiliary locking device provided by the present disclosure may also include a mounting portion 20, and the mounting portion 20 may include the above-mentioned mounting plate 21, a second through hole 22, and a fastener (not shown in the figure). The second through hole 22 may be provided on the mounting plate 21, and the fastener may be inserted into the cabinet door 40 after passing through the mounting plate 21 through the second through hole 22, so as to install the cover body 10 on the cabinet door 40. According to an embodiment provided by the present disclosure, an internal thread may be formed in the second through hole 22, and an internal threaded hole corresponding to the position of the second through hole 22 may be provided on the cabinet door, and the fastener may be a bolt capable of cooperating with the internal thread, and the fastener may be threadedly connected to the cabinet door after passing through the second through hole 22. This connection method not only ensures the detachable connection between the auxiliary locking device and the cabinet door 40, but also effectively ensures the connection strength between the mounting portion 20 and the cabinet door 40. In the present disclosure, the number of the second through hole 22 and the fastener may be set to be multiple, so as to further improve the connection strength between the auxiliary locking device and the cabinet door 40.

[0037] Reference Figure 1-Figure 3 In the present disclosure, the cover body 10 and the mounting plate 21 can be integrally formed, which can improve the overall strength and rigidity of the auxiliary locking device, making the auxiliary locking device more durable and reliable. At the same time, the connection strength between the cover body 10 and the mounting plate 21 is ensured, and the loosening and falling off between the cover body 10 and the mounting plate 21 are effectively avoided.

[0038] According to the embodiment provided by the present disclosure, the cover body 10 and the mounting plate 21 can be made of stainless steel respectively. In this way, the cover body 10 and the mounting plate 21 have strong corrosion resistance, which can effectively improve the service life of the auxiliary locking device.
