Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1 to 5 As shown, the electric access control system includes a door frame 10 and a door body 20. The door frame 10 includes a horizontally arranged horizontal bar 11 and a vertically arranged column 12. An electric locking assembly 30 is provided inside the horizontal bar 11.

[0028] The horizontal bar 11 has a hollow control channel 111 inside, and the side wall of the control channel 111 has several mounting through holes 112. The tail of the control channel 111 has an electrical mounting cavity 113.

[0029] The electric locking assembly 30 includes a control rack 31, an electric telescopic device 32, and a plurality of locking heads S. The electric telescopic device 32 drives the control rack 31, which is disposed in the control channel 111. The electric telescopic device 32 is disposed in the electrical mounting cavity 113, and the locking heads S are rotatably disposed in the mounting through hole 112.

[0030] like Figure 6 and Figure 7 As shown, the locking head S includes a drive pinion 33, on which a pair of detachable locking blocks 34 are provided, and the control rack 31 cooperates with the drive pinion 33.

[0031] The drive pinion 33 includes a columnar pinion body 331. The outer wall of the middle part of the pinion body 331 is provided with a plurality of circumferentially arranged drive tooth grooves 332. The drive tooth grooves 332 cooperate with the control rack 31. The side wall of the pinion body 331 is provided with a first keyway 333 axially. The locking sector block 34 includes a semi-circular sector block body 341. The center of the sector block body 341 is provided with a tubular sector block sleeve 342. The inner wall of the sector block sleeve 342 is provided with a pair of second keyways 343. The second keyways 343 are fixedly connected to the first keyways 333 by a key.

[0032] Additionally, the electrical installation cavity 113 houses a controller and a switching power supply (not shown in the figure). This switching power supply provides power to the controller and the electric expansion joint 32.

[0033] In addition, both the drive pinion 33 and the locking block 34 are made of high-strength steel to prevent forced opening.

[0034] In addition, the electrical installation cavity 113 is equipped with a removable protective cover for easy maintenance.

[0035] The working principle of this electric access control system will be explained below.

[0036] like Figure 8 As shown, at this time, the outer circle of the locking block 34 faces downward, and the locking block 34 clamps the door 20, preventing the door 20 from opening.

[0037] like Figure 9 As shown, when the user swipes the access card, the controller powers on the electric telescopic device 32. The electric telescopic device 32 then retracts and simultaneously pulls the control rack 31 to move in direction F. The control rack 31 drives the drive pinion 33, which in turn drives the locking block 34 to rotate clockwise until the outer circle of the locking block 34 faces upward. The locking block 34 then releases the door 20, allowing the door 20 to be opened freely.

[0038] This electric access control system uses bidirectional locking blocks, effectively locking both the inner and outer sides of the door without directional limitations. Furthermore, the use of multiple locking heads provides strong resistance to forced entry. Due to its built-in structure, the system occupies a small space and is easy to install.

[0039] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
