[0015] Figure 3 yes Figure 1 An enlarged diagram of the lower part.

[0016] Figure 4 This is a schematic diagram (II) of the present invention. Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-4 An electromechanical dual-control lock suitable for a double-lock mechanism includes a frame 10, a main lock sliding plate 21 slidably mounted on the frame 10, and a main lock tongue 20 fixed on the main lock sliding plate 21. The main lock tongue 20 is a locking component for locking a special storage cabinet.

[0019] like Figure 2 The main lock sliding plate 21 is provided with a drive strip hole 24.

[0020] like Figure 2 A mechanical lock sliding plate 30 is slidably mounted on the frame 10. An electronic lock motor 31 is fixed on the mechanical lock sliding plate 30. The output shaft of the electronic lock motor 31 is fixed to a rotating wheel 32. The rotating wheel 32 is equipped with an eccentric column 33, which is inserted into a drive strip hole 24. Driven by the output shaft of the electronic lock motor 31, the eccentric column 33 makes a circular motion around the axis of the output shaft of the electronic lock motor 31. Then, relying on the cooperation between the eccentric column 33 and the drive strip hole 24, it finally drives the main lock sliding plate 21 and the main lock tongue 20 to reciprocate linearly, thereby realizing the switching between the locked and unlocked states of the main lock tongue 20.

[0021] In the existing technology, the rotation of the electronic lock motor 31 is controlled by an electronic / software control system to achieve "dual-person dual-lock" management.

[0022] The main problem this application aims to solve is the failure of the electronic / software control system.

[0023] like Figure 2 The main lock sliding plate 21 is hinged to one end of the first pull rod 41.

[0024] like Figure 3 A primary lock is rotatably mounted on the frame 10, and a zone frame 44 is slidably mounted on the frame 10. The primary lock includes a primary lock cylinder 40. When the zone frame 44 slides to one end near the main lock tongue 20, the zone frame 44 is located outside the primary lock cylinder 40. The primary lock cylinder 40 is keyed to the primary lock disc 42. An outwardly protruding traction part 43 is fixed on the primary lock disc 42. The traction part 43 is hinged to the other end of the first pull rod 41.

[0025] like Figure 3 The second tie rod 51 is hinged to the frame 44.

[0026] like Figure 3 The frame 10 is equipped with a secondary lock that rotates on it. The secondary lock includes a secondary lock cylinder 50, which is keyed to a secondary lock disc 52. The primary lock disc 42 is hinged to the other end of the second pull rod 51.

[0027] like Figure 3 To facilitate control of the sliding range of the character frame 44, a character frame strip hole 45 is provided on the character frame 44, and a first limiting hole 13 is fixed on the frame 10, with a first limiting post fixed inside the first limiting hole 13. The first limiting post can limit the sliding range of the character frame 44.

[0028] like Figure 2 To facilitate control of the sliding range of the main lock sliding plate 21, a sliding plate slot 22 is provided on the main lock sliding plate 21, and a second limiting post (not shown in the figure) is fixed on the frame 10. The second limiting post can limit the sliding range of the main lock sliding plate 21.

[0029] like Figure 2 In order to facilitate the detection and control of the lower limit of the main lock sliding plate 21, the probe column 23 is fixed on the main lock sliding plate 21, and the limit switch 11 is provided below the probe column 23. The limit switch 11 is set on the frame 10.

[0030] like Figure 2To facilitate the adjustment of the position of the limit switch 11 and achieve precise detection of the lower limit of the control main lock sliding plate 21, the limit switch 11 is fixed on the detection base, which has a base slot 12. The frame 10 and the detection base are fastened together by bolts 13, which are located inside the base slot 12. Thus, before tightening the bolts, the position of the limit switch 11 can be adjusted by selecting different positions of the bolts 13 in the base slot 12.

[0031] To facilitate rotation, the drive strip hole 24 is located on the side panel 25 of the main lock sliding plate 21, and the side panel 25 and the main plate of the main lock sliding plate 21 are L-shaped.

[0032] Its working principle is as follows:

[0033] The electronic lock motor 31 is rotated and the main lock tongue 20 is controlled in the unlocked or locked state by the electronic / software control system, thereby realizing the "double-person double-lock" management of the medicine cabinet. This is existing technology and will not be described in detail.

[0034] The mechanical "double-person, double-lock" management system will now be explained in detail.

[0035] I. Unlock

[0036] like Figure 2 The main locking bolt 20 is in the locked state, and it is unlocked.

[0037] S11, such as Figure 3 Insert the key into the secondary lock cylinder 50 and rotate the secondary lock cylinder 50 clockwise / counterclockwise to unlock the secondary lock. At the same time, the secondary lock disc 52 also rotates synchronously. When the secondary lock disc 52 rotates, it pulls the second pull rod 51 to move, similar to a crank-slider mechanism. The second pull rod 51 pulls the zone frame 44 to slide downward. The zone frame 44 no longer restricts the rotation of the primary lock disc 42 and the traction part 43, and the primary lock is in an unlockable state.

[0038] S12. Insert the key into the primary lock cylinder 40 and turn the primary lock cylinder 40 clockwise / counterclockwise to unlock the primary lock.

[0039] S13. During the rotation of the primary lock cylinder 40, the primary lock disc 42 rotates synchronously, which pulls the first pull rod 41 to move. The first pull rod 41 pulls the mechanical lock sliding plate 30 to slide downward. The electronic lock motor 31, as well as the rotating wheel 32 and the eccentric column 33 fixed on the mechanical lock sliding plate 30, all slide downward synchronously. The eccentric column 33 drives the side panel 25 and the main lock sliding plate 21 to slide downward synchronously. The main lock sliding plate 21 drives the lock tongue plate 350 to slide downward synchronously, and the lock tongue plate 350 enters the unlocked state.

[0040] II. Locking

[0041] S21. Insert the key into the primary lock cylinder 40 and turn the primary lock cylinder 40 in the reverse direction.

[0042] S22. During the rotation of the primary lock cylinder 40, the primary lock disc 42 rotates synchronously, which pulls the first pull rod 41 to move. The first pull rod 41 pulls the mechanical lock sliding plate 30 to slide upward. The electronic lock motor 31, as well as the rotating wheel 32 and the eccentric column 33 fixed on the mechanical lock sliding plate 30, all slide upward synchronously. The eccentric column 33 drives the side panel 25 and the main lock sliding plate 21 to slide upward synchronously. The main lock sliding plate 21 drives the lock tongue plate 350 to slide upward synchronously, and the lock tongue plate 350 enters the locked state.

[0043] S23. Insert the key into the secondary lock cylinder 50, rotate the secondary lock cylinder 50 in the opposite direction, and the secondary lock is locked.

[0044] S24. At the same time, the secondary locking disc 52 also rotates synchronously. When the secondary locking disc 52 rotates, it pulls the second pull rod 51 to move, similar to a crank-slider mechanism. The second pull rod 51 pulls the zone frame 44 to slide upward. The zone frame 44 is stuck on the outside of the primary locking disc 42, so that the primary locking disc 42 and the traction part 43 cannot rotate.

[0045] S25. Remove the key from the secondary lock cylinder 50, and the secondary lock is locked.

[0046] In this way, the mechanical locking mechanism can also switch between the unlocked and locked states of the latch plate 350, thereby achieving "two people, two locks" management.

[0047] Features of this application:

[0048] This application includes two locking mechanisms:

[0049] There are mechanical locking mechanisms and electronic / software control systems that control the motor's locking mechanism. However, the two do not interfere with each other and can be used independently.

[0050] During the operation of the aforementioned mechanical locking mechanism, the locking mechanism of the motor controlled by the electronic / software control system cannot affect it; similarly, the aforementioned mechanical locking mechanism does not interfere with the locking mechanism of the motor controlled by the electronic / software control system.

[0051] For other details, please refer to the existing technology.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
