Description

Technical Field

[0001] This utility model relates to the technical field of safe accessories, and more specifically, to an electronic combination lock for a safe. Background Technology

[0002] Existing electronic combination locks for safes consist of a panel installed on the safe and a mechanical lock. The outer wall of the panel has a keypad for the combination. The user needs to enter the correct combination to unlock the mechanical lock and open the safe door. Companies often place a safe in their offices to store company seals or confidential documents. In some special circumstances (such as when someone other than the user is in the office and needs to open the safe), the exposed keypad makes it difficult to conceal the combination when entering it, allowing malicious eavesdroppers to easily learn the combination. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides an electronic combination lock for a safe, comprising a panel and a cover plate. The panel has multiple password keys spaced apart and arranged irregularly. The cover plate is slidably mounted on the panel and has an input hole. When any one of the password keys is completely within the range of the input hole, the cover plate is adapted to block the remaining password keys.

[0004] Optionally, the panel includes a rear shell and a front cover, the rear shell having a sliding groove on the side near the front cover, and the baffle sliding within the sliding groove.

[0005] Optionally, the bottom of the sliding groove is provided with a button groove, and multiple password buttons are located in the button groove, with the shield abutting against the bottom of the sliding groove.

[0006] Optionally, the front cover is connected to the rear shell, and the front cover has an operation opening that communicates with the button groove. The button groove is located within the range of the operation opening, and the size of the baffle is larger than the size of the operation opening.

[0007] Optionally, the top of the panel is provided with a mounting groove, which communicates with the sliding groove so that the shield can be installed in the sliding groove.

[0008] Optionally, a rubber plug is inserted into the opening of the mounting groove, and the rubber plug is adapted to cover and seal the mounting groove.

[0009] Optionally, the panel is provided with a display screen for displaying the number of digits in the password, and the display screen is covered with a privacy film.

[0010] Optionally, the panel is provided with a lock cylinder hole for inserting a mechanical lock cylinder.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] 1. When entering the password, all password keys except the one corresponding to the input hole are covered. During the password input process, the cover can be moved by the finger inserted into the input hole, which is highly concealed. In addition, the password keys are arranged irregularly, and only the user knows the detailed arrangement structure. Others cannot deduce it from the conventional and regular arrangement of password keys, which further improves the concealment of the password input process and makes it difficult for others to know the password.

[0013] 2. If the user feels that the cover is unnecessary, the cover can be removed through the mounting slot. When the user wants to use it later, he / she can simply insert the cover from the mounting slot into the sliding groove. The user can choose according to his / her needs.

[0014] 3. Users can set the password length according to their needs. When entering the password, the password key will not make a sound. The display screen will show the password length to prompt the user through visual feedback, but will not directly display the password. At the same time, the privacy screen can play a role in preventing others from knowing exactly how many digits the password is. Compared with key prompts, it is more discreet.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-2 This application will be described in further detail.

[0019] This utility model embodiment provides an electronic combination lock for a safe, see reference... Figure 1 and Figure 2The electronic combination lock for the safe includes a panel 1 and a cover plate 2. The panel 1 is suitable for installation on the safe door, and has multiple keypads 11 spaced apart on it. The cover plate 2 is slidably mounted on the panel 1 and has an input hole 21. When any one keypad 11 is completely within the range of the input hole 21, the cover plate 2 is suitable for blocking the remaining keypads 11. During the input process, the cover plate 2 can be moved by a finger inserted into the input hole 21, providing a high degree of concealment and making it difficult for others to know the combination.

[0020] Reference Figure 1 and Figure 2 The panel 1 includes a rear shell 12 and a front cover 13. Multiple keypad buttons 11 are mounted on the side of the rear shell 12 near the front cover 13. A baffle plate 2 slides between the rear shell 12 and the front cover 13. After the baffle plate 2 is assembled, the rear shell 12 and the front cover 13 are welded and fixedly connected. A sliding groove 14 is provided on the side of the rear shell 12 near the front cover 13. The baffle plate 2 slides within the sliding groove 14, with its two sides abutting against the bottom of the sliding groove 14 and the front cover 13, respectively. A keypad groove 15 is provided at the bottom of the sliding groove 14. Multiple keypad buttons 11 are located within the keypad groove 15 and do not protrude from it, thus preventing the keypad buttons 11 from interfering with the sliding of the baffle plate 2. The front cover 13 has an operation opening 16 that communicates with the button recess 15. The button recess 15 is located within the operation opening 16. The size of the baffle 2 is larger than the size of the operation opening 16, so that the baffle 2 cannot be detached from the sliding recess 14 through the operation opening 16. The rear shell 12 and the front cover 13 are designed separately, which also facilitates the processing of the sliding recess 14 and the button recess 15.

[0021] The multiple keypads 11 are arranged irregularly; that is, they are not arranged in the sequence "0, 1, 2, 3, 4, 5, 6, 7, 8, 9", but rather in the order "1, 5, 8, 6, 3, 9, 2, 0, 7, 4". The detailed arrangement is known only to the user, and others cannot deduce it from a conventional, regular keypad arrangement, further enhancing the concealment of the password input process and making it difficult for others to obtain the password.

[0022] Reference Figure 1 and Figure 2 During the password input process, the shield 2 can be moved by the finger inserted into the input hole 21. To reduce the ease with which the finger moves the shield 2, this example preferably uses an opaque plastic material for the shield 2. During the sliding of the shield 2 within the sliding groove 14, each password key 11 can be positioned within the range of the input hole 21, thus allowing each password key 11 to be pressed after the shield 2 is moved.

[0023] Reference Figure 1 and Figure 2 The top of the rear shell 12 has a mounting groove 17, which communicates with the sliding groove 14 for the cover plate 2 to be installed in the sliding groove 14. A rubber plug 171 is interference-fitted into the opening of the mounting groove 17 to cover and seal the mounting groove 17. If the user feels that the cover plate 2 is unnecessary, the user can remove the rubber plug 171 and then pull the cover plate 2 out of the mounting groove 17; when the user wants to use it later, he only needs to insert the cover plate 2 from the mounting groove 17 into the sliding groove 14 and then insert the rubber plug 171 into the mounting groove 17. When the panel 1 is assembled with the door of the safe, the rear shell 12 protrudes from the front side of the door, so that the mounting groove 17 is not blocked by the door, thus not affecting the removal of the cover plate 2.

[0024] Reference Figure 1 and Figure 2 The rear cover 12 houses a circuit board (not shown) and a display screen 18. The display screen 18 and multiple password buttons 11 are electrically connected to the circuit board. The front cover 13 has mounting holes for inserting the display screen 18. The password buttons 11 are silent buttons, meaning they do not emit a "beep" sound when pressed. The display screen 18 displays the password as asterisks (*), providing visual feedback to indicate the number of digits entered. Additionally, the display screen 18 has a privacy film to enhance the concealment of the password input process, making it difficult for others to obtain the password.

[0025] Reference Figure 1 and Figure 2 The rear cover 12 and the front cover 13 have interconnected and concentric lock cylinder holes 19. During assembly, the lock cylinder in the mechanical lock will be inserted into the lock cylinder hole 19 so that the user can use the mechanical key to insert the lock cylinder to unlock it.

[0026] The implementation principle of an electronic combination lock for a safe according to this application embodiment is as follows: When entering the password, except for the password key 11 corresponding to the input hole 21, all other password keys 11 are covered. During the password input process, the cover plate 2 can be moved by the push of the finger inserted into the input hole 21, which provides a high degree of concealment. In addition, the password keys 11 are arranged irregularly, and only the user knows the detailed arrangement structure. Others cannot deduce the password from the conventional and regular arrangement of the password keys 11. When entering the password, the password keys 11 do not make a sound. The display screen 18 will display the number of digits of the password to prompt the user through visual feedback, but will not directly display the password. At the same time, the anti-peeping film can play a role in preventing others from knowing the exact number of digits of the password. Compared with the keypad, which has a prompt sound, it is more concealed.
