The housing 10 can be made of metal or plastic with predetermined rigidity, preferably made of metal. The housing 10 has a housing space 11 for housing related components. The housing 10 has an opening 12 on one side along the first direction D1. It is worth mentioning that the housing space 11 can be provided with related structures for positioning, fixing or pivoting the components to be accommodated. These related structures are technical means or structures that are well known or commonly used by ordinary knowledgeable persons in the technical field to which the present invention belongs, and will not be elaborated here.

The bolt stopper unit 20 can be made of metal or plastic with a predetermined rigidity, preferably made of metal. The bolt stopper unit 20 is pivoted to the opening 12 along a second direction D2 perpendicular to the first direction D1 and is located in the accommodation space 11. In other words, the bolt stopper unit 20 can be provided with a through hole along the second direction D2 and then a shaft is used to penetrate the through hole, and a torsion spring or a hinge with the same function is sleeved on one or both ends of the shaft, thereby achieving the function that the bolt stopper unit 20 can rotate under force and reset when the external force is removed.

In addition, the bolt stopper unit 20 has a bolt stopper portion 21 and a push portion 22 on both sides along the first direction D1. The bolt stopper portion 21 is adjacent to the opening 12, and is configured to stop a bolt 92 of the door panel lock. Further, the bolt stopper portion 21 may be a triangular groove structure, so as to accommodate the bolt 92 when the door panel is closed in the door frame 91. Furthermore, the push portion 22 is a convex portion formed integrally with the body of the bolt stopper unit 20, and the push portion 22 is a triangular structure along the second direction D2.

The linkage drive unit 30 is disposed in the accommodation space 11; for example, a frame may be provided at a position corresponding to the accommodation space 11 to position the linkage drive unit 30, and a lock hole or through hole may be provided to fix the linkage drive unit 30 by means of locking or the like. Further, the linkage drive unit 30 has a drive shaft 31 displaced along the second direction D2. For example, the linkage drive unit 30 may be a linear electromagnetic valve, a pneumatic cylinder, a hydraulic cylinder, etc. Preferably, the linkage drive unit 30 is a linear electromagnetic valve, which is actuated after receiving a signal.

Incidentally, the cathode lock device 1 or the linkage drive unit 30 of the present invention may include a circuit board module, which can be connected to a power source and has the ability to receive and process signals, so that the user can transmit a signal such as door opening to the linkage drive unit 30 by wired or wireless means, so that the linkage drive unit 30 can be actuated after receiving the signal. Among them, the user can use an electronic device with a corresponding application (APP) installed, such as a smart phone, to trigger and transmit the signal.

The connecting rod module 40 includes a first connecting rod 41 and a second connecting rod 42. The first connecting rod 41 and the second connecting rod 42 can be made of metal or plastic material with predetermined rigidity, preferably made of metal.

Furthermore, the first connecting rod 41 is a long strip structure, such as a long elliptical plate. One end of the first connecting rod 41 is connected to the drive shaft 31, and the other end of the first connecting rod 41 is connected to one end of the second connecting rod 42. Preferably, both ends of the first connecting rod 41 can have a through hole respectively, so that one end of the first connecting rod 41 can be rotatably connected to the drive shaft 31 and the other end of the first connecting rod 41 can be rotatably connected to one end of the second connecting rod 42 by means of a latch.

It is worth mentioning that one end of the driving shaft 31 is in a U-shaped structure to clamp and pivot one end of the first connecting rod 41.

In addition, the second connecting rod 42 is an L-shaped structure. The connection of the two arms of the second connecting rod 42 is pivoted on the housing 10; for example, a blind hole or a through hole may be provided in the accommodating space 11, and the connection of the two arms of the second connecting rod 42 may be a through hole, so that the second connecting rod 42 can be pivoted on the housing 10 by means of a latch or the like. It is worth mentioning that one end of the second connecting rod 42 is a U-shaped structure to clamp the plate-shaped first connecting rod 41 and pivot the other end of the first connecting rod 41. In addition, the other end of the second connecting rod 42 is a stopper 4211, and the stopper 4211 selectively stops the push portion 22 or separates from the push portion 22. It is worth mentioning that the two arms of the second connecting rod 42 are a first arm 421 and a second arm 422, respectively, and the first arm 421 is an arm having the stopper 4211, and the first arm 421 is an L-shaped structure.

Furthermore, the housing 10 is provided with a guide track 13 at the connection point between the other end of the first connecting rod 41 and one end of the second connecting rod 42; the guide track 13 is a track that is curved in the direction of the bolt limiting unit 20. One end of the second connecting rod 42 is provided with a guide portion 4221 facing the guide track 13, and the guide portion 4221 is embedded in the guide track 13.

For example, when the linkage drive unit 30 is not actuated, the stopper 4211 is located on the rotation path of the pusher 22. When the door panel is pushed open, the bolt 92 pushes against the inner wall surface of the bolt stopper 21 to drive the bolt stopper 20 to rotate; at this time, since the stopper 4211 is located on the rotation path of the pusher 22, the pusher 22 pushes against the stopper 4211, so that the bolt stopper 20 is restricted in freedom and cannot rotate. Therefore, the bolt 92 cannot be separated from the bolt stopper 21 to achieve the purpose of being unable to open the door.

Furthermore, when the linkage drive unit 30 is actuated, the stopper 4211 is driven by the connecting rod module 40 to separate from the rotation path of the pusher 22. When the door panel is pushed open, the bolt 92 pushes against the inner wall surface of the bolt stopper 21 to drive the bolt stopper 20 to rotate; at this time, since the stopper 4211 is not located on the rotation path of the pusher 22, the bolt stopper 20 can be smoothly rotated. Therefore, the bolt 92 can separate from the bolt stopper 21 to achieve the purpose of opening the door.

Please refer to Figure 6, which is an exploded schematic diagram of the second embodiment of the cathode lock device of the present invention, and its combined schematic diagram is similar to the first embodiment. In this embodiment, the components with the same component symbols have the same or similar configuration and operation as the aforementioned embodiments, and the same or similar parts will not be repeated here.

As shown in the figure, the main difference between this embodiment and the above-mentioned embodiment lies in the linkage drive unit 30. The linkage drive unit 30 further includes a sleeve 32; one end of the drive shaft 31 is a conical structure; one end of the sleeve 32 has a concave hole for sleeve-mounting on one end of the drive shaft 31, and the other end of the sleeve 32 is a U-shaped structure to clamp and pivot one end of the first connecting rod 41.

Please refer to Figures 7 and 8, which are the block diagram and structure diagram of the access control system of the present invention respectively.

As shown in the figure, the access control system 5 of the present invention comprises a door 90, a cathode lock device 1 as described above, and a reader 51. The door 90 is rotatably arranged on a door frame 91, and the door 90 has a lock 901, and the lock 901 has a bolt 92.
