DETAILED DESCRIPTION

[0021] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0022] Please refer to Figures 1-6 The present application provides an embodiment: a magnetic lock, comprising a shell 1, the shell 1 is provided with a lock tongue 5 and a driving piece 2; one side of the lock tongue 5 is linked with the driving piece 2 through the first knob 9 provided, and the other side of the lock tongue 5 is linked with the second knob 10 provided; the second knob 10 is rotatably installed on the first knob 9, and the first knob 9 and the second knob 10 are independently rotated on the shell 1, so that the lock tongue 5 slides in the shell 1.

[0023] As the central axes of the two knobs coincide, and the second knob 10 is vertically placed on the first knob 9, and the first knob 9 and the second knob 10 can both promote the sliding of the lock tongue 5, so that the lock can complete the unlocking action of the lock through the rotation of the two knobs; in particular, the second knob 10 can rotate freely on the first knob 9, so that the first knob 9 can independently promote the sliding of the lock tongue 5, and the second knob 10 can also promote the independent sliding of the lock tongue, so that in specific use, the key can be used to promote the rotation of the second knob 10 driven by the lock cylinder, to complete the manual unlocking of the lock; at the same time, when the driving piece 2 promotes the rotation of the first knob 9, the automatic opening of the lock can also be realized; wherein the driving piece 2 is preferably an electric motor.

[0024] Therefore, the number of parts for controlling the sliding of the lock tongue is reduced, the structure of the parts linked with the lock tongue 5 is simplified, the structure of the lock tongue 5 and the external structure of the two driving members linked with the lock tongue 5 are regular, the internal space of the shell 1 is neat and beautiful, and the weight of the lock is reduced.

[0025] In order to simplify the transmission structure of the first driving member 9 and the lock tongue 5, the first driving member 9 is connected with the connecting surface 13 arranged on the lock tongue 5 through the protruding part 6, so that the first driving member 9 promotes the sliding of the lock tongue 5. Therefore, the power transmission between the first driving member 9 and the lock tongue 5 can be completed by machining a connecting surface 13 on the side surface of the lock tongue 5, and the machining of the connecting surface 13 is simple and convenient.

[0026] In addition, the first driving member 9 is engaged with the gear on the output shaft of the driving member 2 through the gear rack 14. The engagement of the gear and the gear rack 14 can also ensure that the power of the driving member 2 can be stably and reliably transmitted to the first driving member 9.

[0027] In order to improve the torque and reduce the output power of the driving member 2, the protruding part 6 is arranged on the upper end surface of the first driving member 9 close to the rotating shaft, and the gear rack 14 is arranged on the side surface of the first driving member 9 away from the rotating shaft. Specifically, the protruding part 6 is arranged between the gear rack 14 and the first driving member 9. Therefore, by increasing the distance between the protruding part 6 and the gear on the output shaft of the driving member 2, the length of the force arm is increased, so as to reduce the output power of the driving member 2 and improve the service life of the driving member 2.

[0028] Further, since the integrated circuit board 3 is arranged in the shell 1, the inductive switch 11 is arranged on the integrated circuit board 3, and the trigger part 17 for triggering the inductive switch 11 is arranged on the first driving member 9, the number of inductive switches 11 is two, and the two inductive switches 11 are arranged on the path of the trigger part 17. Therefore, the two inductive switches 11 can be used to control the opening or closing of the driving member 2.

[0029] On the basis of the above-mentioned scheme, the second driving member 10 is in contact with the protruding block 12 arranged on the lock tongue 5 through the driving block 15 arranged on the second driving member 10, so as to promote the sliding of the lock tongue 5. Therefore, the sliding of the lock tongue 5 can be stably promoted by the second driving member 10. Therefore, the power transmission structure between the second driving member 10 and the lock tongue 5 can also be simplified, and the driving block 15 is transversely arranged on the radial direction of the second driving member 10. Therefore, when the key is inserted, the second driving member 10 takes the lock cylinder as the rotating fulcrum, the driving block 15 is pressed against the protruding block 12, the lock tongue 5 is rotated by the leverage principle, and the lock tongue 5 can be more easily and conveniently slid in the shell 1.

[0030] In order to facilitate the second toggle 10 to reset quickly after the external force disappears, one side of the second toggle 10 is further provided with a reset spring 7, and the second toggle 10 is reset by the reset spring 7 when there is no external force.

[0031] Specifically, one end of the reset spring 7 is connected with a fixing 8 arranged in the shell 1, and the other end of the reset spring 7 is connected with a connecting hole 16 arranged on the second toggle 10.

[0032] In addition, since the shell 1 is further provided with a guide 4, and the guide 4 guides the sliding of the lock tongue 5, the guide 4 can guide the directional sliding of the lock tongue 5. Specifically, one side of the guide 4 facing the lock tongue 5 is provided with a groove, and the groove guides the directional sliding of the lock tongue 5.

[0033] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
