Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] An emergency opening mechanism for a combination lock, such as Figures 1 to 8 As shown, the lock includes a door lock body 1, a handle 2 that is rotatably mounted on the door lock body 1, a numeric keypad area 3, a face recognition area 14 and a card reading area 15 on the door lock body 1, and a fingerprint recognition area 16 on the handle 2.

[0019] The door lock body 1 has a receiving groove 4 inside, and a combination dial 6 is installed in the receiving groove 4. The door lock body 1 also has a placement groove 5 inside, and a cover 7 is placed in the placement groove 5. The cover 7 is used to seal the opening of the receiving groove 4, thereby protecting the combination dial 6 inside the receiving groove 4.

[0020] Specifically, in this embodiment, the cover 7 includes a base plate 71 and a decorative plate 72. The decorative plate 72 is disposed on the base plate 71. The decorative plate 72 is fixedly connected to the base plate 71 or the two are integrally formed. The base plate 71 covers the opening of the receiving groove 4. The outer contour of the decorative plate 72 is adapted to the inner contour of the placement groove 5, thereby realizing the positioning of the cover 7 by the placement groove 5 and ensuring the stability of the cover 7.

[0021] A magnet 17 is installed in the placement groove 5. The magnet 17 is used to hold the cover 7 tightly. The cover 7 is made of magnetic material. The magnetic attraction of the magnet 17 on the cover 7 ensures that the cover 7 is stably placed in the placement groove 5, preventing the cover 7 from falling out of the placement groove 5 without external force. By using the magnetic attraction of the magnet 17, the opening operation of the cover 7 is more convenient.

[0022] Pressing one end of the cover 7 causes the other end of the cover 7 to lift up and detach from the mounting groove 5. Then, by moving and rotating the cover 7, the keypad 6 inside the receiving groove 4 is exposed.

[0023] It should be noted that, specifically, to achieve the effect of pressing one end of the cover 7 to make the other end of the cover 7 lift up and disengage from the mounting groove 5, one end of the cover 7 is provided with a groove 8, and there is a gap 9 between the bottom surface of the groove 8 and the bottom surface of the mounting groove 5. When the cover 7 is pressed at the position corresponding to the gap 9, the cover 7 moves downward at that position until the bottom surface of the groove 8 touches the bottom surface of the mounting groove 5. Since other parts of the cover 7 are in contact with the bottom surface of the mounting groove 5 (lever principle), at this time the other end of the cover 7 lifts up and disengages from the mounting groove 5.

[0024] Furthermore, after one end of the cover 7 is lifted off the mounting groove 5 and moved outward, the cover 7 can rotate to either side to expose the keypad 6 in the receiving groove 4, thereby facilitating user operation.

[0025] The bottom of the mounting groove 5 is provided with a strip structure, and the cover 7 is provided with a movable part 11. The movable part 11 is movably disposed in the strip structure, and the strip structure is used to guide and limit the movable part 11.

[0026] In this embodiment, the strip structure includes a strip hole 10, and a movable member 11 passes through the strip hole 10. The movable member 11 can slide along the strip hole 10 or rotate relative to the strip hole 10. The strip hole 10 guides and limits the stroke of the movable member 11, thereby ensuring the stability of the user when moving the cover 7 and limiting the stroke of the cover 7.

[0027] As an alternative, the strip structure includes a strip groove 18, into which a movable member 11 is inserted. The movable member 11 can slide along the strip groove 18 or rotate relative to the strip groove 18. The strip groove 18 guides and limits the stroke of the movable member 11, thereby ensuring the stability of the user when moving the cover 7 and limiting the stroke of the cover 7.

[0028] When the user needs to use the keypad 6, they only need to press the corresponding gap 9 of the cover 7 with external force, causing the cover 7 to move downwards until the bottom surface of the groove 8 touches the bottom surface of the mounting groove 5. At this time, the other end of the cover 7 will lift up and detach from the mounting groove 5. Then, the cover 7 is moved outwards, that is, the movable part 11 slides along the strip hole 10. Then, the cover 7 is rotated to any side with the movable part 11 as the axis. As part of the cover 7 rotates to the outside, the opening of the receiving groove 4 is no longer covered by the cover 7, and the keypad 6 inside the receiving groove 4 is exposed. After use, simply rotate the cover 7 again, move the cover 7 so that the cover 7 is facing the mounting groove 5, and finally put the cover 7 back into the mounting groove 5.

[0029] One end of the combination dial 6 has a connecting hole 12 for fasteners to pass through, and the other end of the combination dial 6 has an opening slot 13 for fasteners to pass through. That is, when installing the combination dial 6, the corresponding fastener (not shown in the figure) is first passed through the connecting hole 12 and connected to the door lock body 1. The fastener is preferably a bolt. Then the corresponding fastener is passed through the opening slot 13 and connected to the door lock body 1. The structure of the opening slot 13 can effectively overcome the dimensional deviations generated during the installation process and improve the adaptability and accuracy of the installation.

[0030] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
