Detailed Implementation

[0018] 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.

[0019] An emergency rotating cover opening structure for a lock handle, such as Figures 1 to 8 As shown, it includes a door lock body 1, which is equipped with a numeric keypad area 2, a face recognition area 3, and a card reading area 4.

[0020] The door lock body 1 is provided with a mounting groove 8, and a combination dial 9 is installed in the mounting groove 8. Specifically, one end of the combination dial 9 has a mounting hole 13 for fasteners (not shown) to pass through, and the other end of the combination dial 9 has an opening groove 14 for fasteners to pass through. That is, the corresponding fasteners are connected to the door lock body 1 by passing through the mounting hole 13, and then the corresponding fasteners are connected to the door lock body 1 by passing through the opening groove 14. The fasteners are preferably bolts. It should be noted that the opening groove 14 can effectively overcome the dimensional deviations generated during the installation process and improve the adaptability and accuracy of the installation.

[0021] Furthermore, the combination lock 9 has a positioning part 12, which is adapted to the inner wall contour of the mounting groove 8. After the combination lock 9 is installed into the mounting groove 8, the connecting hole 25 and the opening groove 14 are aligned with the corresponding connecting hole 25 on the door lock body 1. Therefore, not only can the mounting groove 8 be positioned for the positioning part 12 to ensure the stability of the mounting groove 8, but the installation of the combination lock 9 is also more convenient.

[0022] A door handle 5 is rotatably mounted on the door lock body 1. A fingerprint recognition area 6 is provided on the door handle 5. A cover plate 7 for sealing the mounting groove 8 is installed on the door handle 5. In this embodiment, the upper surface of the cover plate 7 is attached to the lower surface of the door handle 5. The cover plate 7 and the door handle 5 are detachably fixed by bolts (not shown in the figure), which facilitates the disassembly, replacement and maintenance of the cover plate 7 in the future.

[0023] Specifically, the cover plate 7 has a countersunk hole 11. The bolt passes through the countersunk hole 11 and is threaded to the door handle 5. The bolt head is located inside the countersunk hole 11, thus hiding the bolt head.

[0024] Turning the door handle 5 causes the cover plate 7 to rotate, allowing the cover plate 7 to open or close the mounting groove 8, thereby hiding the keypad 9 inside the mounting groove 8 or exposing the keypad 9 from the mounting groove 8.

[0025] This allows the keypad 9 to be hidden and protected by covering the mounting slot 8 with the cover plate 7. Moreover, the user only needs to turn the door handle 5 to rotate the cover plate 7 to open or close the mounting slot 8. The operation is simple and convenient.

[0026] A fixing plate 15 is installed at the bottom of the door handle 5. Preferably, the fixing plate 15 is connected to the door handle 5 by bolts. A connecting plate 16 is installed on the fixing plate 15, and a connecting plate 17 is installed on the connecting plate 16. The fixing plate 15, the connecting plate 16, and the connecting plate 17 are also connected by bolts. The fixing plate 15 and the connecting plate 17 cooperate to form an annular groove 18. The door lock body 1 includes a liner 19. A connecting hole 25 is opened on the liner 19. The connecting plate 16 is movably inserted through the connecting hole 25. The liner 19 extends into the annular groove 18. There is a gap 20 between the connecting plate 17 and the liner 19. A wave washer 21 is provided in the gap 20. Through the elastic support of the wave washer 21, the stability of the door handle 5 can be effectively guaranteed. The door handle 5 can rotate stably and make a slight displacement along the axial direction of the connecting hole 25.

[0027] The lower surface of the fixing plate 15 can abut against the upper surface of the liner 19. The liner 19 restricts the waveform washer 21 and the connecting plate 27 from passing through the connecting hole 25. Through the abutment between the lower surface of the fixing plate 15 and the upper surface of the liner 19, and the liner 19 restricting the waveform washer 21 and the connecting plate 27 from passing through the connecting hole 25, the door handle 5 is prevented from completely separating from the door lock body 1.

[0028] Furthermore, the door handle 5 and the door lock body 1 can be kept relatively stable by the positioning component. In this embodiment, the positioning component includes a ball catch 23, a spring 28 and a limiting buckle 24. The door lock body 1 is provided with a receiving groove 27. The ball catch 23 is slidably disposed in the receiving groove 27. The spring 28 is disposed in the receiving groove 27 and connected to the ball catch 23. The door handle 5 is provided with a positioning groove 26 for positioning the ball catch 23. The rotation of the door handle 5 can cause the ball catch 23 to enter or leave the positioning groove 26. The limiting buckle 24 can be pressed onto the door handle 5.

[0029] Specifically, as the door handle 5 rotates, the down-pressing ball 23 causes the compression spring 28 to slide along the receiving groove 27 until the ball 23 enters the positioning groove 26. At this time, the limiting buckle 24 is pressed against the upper surface of the door handle 5. The positioning effect formed by the positioning groove 26 and the ball 23, as well as the pressing effect of the limiting buckle 24 on the door handle 5, ensure the stability of the door handle 5, that is, the door handle 5 cannot rotate or move, thereby ensuring the stability of the cover plate 7.

[0030] As an alternative, the positioning component includes a magnet 22, which is mounted on the door lock body 1. The magnet 22 can hold the door handle 5 in place. The part of the door handle 5 that is magnetically attracted to the magnet 22 can be made of magnetic metal. Alternatively, a magnet can be directly mounted on the door handle 5 to attract the magnet 22. The magnetic attraction of the magnet 22 to the door handle 5 ensures the stability of the door handle 5, that is, the door handle 5 cannot be rotated or displaced, thereby ensuring the stability of the cover plate 7.

[0031] 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.
