[0019] To enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the accompanying drawings. Depending on the different accompanying drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0021] Embodiment

[0022] As Figures 1-6 shown, an access control for community entrance and exit security includes at least a pair of access control boxes 1 arranged at intervals. A walking space for pedestrians to pass through is formed between two access control boxes 1 of the same pair. A rotating shaft 4 is rotatably installed on one side of an access control box 1 facing another access control box 1. An intercepting plate 2 is arranged on the outer peripheral surface of the rotating shaft 4, and the rotating shaft 4 is connected to a first rotary power source 15; wherein, a first locking member 11 is arranged on the outer peripheral surface of the rotating shaft 4, and a second rotary power source 6 is arranged in the access control box 1, and the output end of the second rotary power source 6 is connected to a second locking member 7.

[0023] Specifically, the access control is provided with an identifier 3 for identifying personnel and a processor. The identifier 3 for identifying personnel and the processor are mature existing technologies, and the specific structures of the identifier 3 for identifying personnel and the processor will not be described in detail here. After the identifier 3 for identifying personnel identifies a person, it determines whether to release. When it is determined that release is required, the first rotary power source 15 outputs power, drives the intercepting plate 2 to rotate through the rotating shaft 4, and opens the walking space for personnel to pass through. When the walking space is in a closed state, the second rotary power source 6 drives the second locking member 7 to lock the first locking member 11. When someone forcibly breaks through the access control or impacts the intercepting plate 2 due to not observing the access control, the second locking member 7 and the first locking member 11 bear the impact force, reducing the force on the transmission structure between the first rotary power source 15 and the rotating shaft 4 or the first rotary power source 15, and increasing the service life of the access control.

[0024] Furthermore, a plurality of convex blocks 19 are arranged on the outer peripheral surface of the first locking member 11, and a locking groove 18 is formed between two adjacent convex blocks 19. The second locking member 7 is adapted to the locking groove 18, and the first locking member 11 is locked by screwing the second locking member 7 into the locking groove 18. Preferably, the cross-section of the second locking member 7 and the locking groove 18 is generally T-shaped, arc-shaped, etc., which is beneficial to increasing the contact surface between the second locking member 7 and the convex blocks 19, and further reducing the possibility of damage to the second locking member 7.

[0025] Furthermore, a first transmission gear 17 is provided on the rotating shaft 4, and a second transmission gear 16 meshed with the first transmission gear 17 is provided at the output end of the first rotary power source 15. The first rotary power source 15 drives the second transmission gear 16 to rotate, and drives the rotating shaft 4 to rotate through the first transmission gear 17.

[0026] Furthermore, the first rotary power source 15 is movably installed in the access control box 1. A movable plate 12 is provided in the access control box 1. An installation plate 13 is provided at the bottom of the first rotary power source 15. A fastener 14 is provided between the movable plate 12 and the installation plate 13. A drive shaft 8 is provided at the output end of the second rotary power source 6. External threads are provided on the outer peripheral surface of the drive shaft 8. A drive sleeve 9 is provided outside the drive shaft 8. Internal threads adapted to the external threads are provided on the inner peripheral surface of the drive sleeve 9. A guide member 10 is provided on one side of the drive sleeve 9. A guide groove adapted to the guide member 10 is provided on the access control box 1. The drive sleeve 9 is connected to the movable plate 12. During the process of the second rotary power source 6 driving the second locking member 7 to lock the first locking member 11, the drive shaft 8 will be synchronously driven to rotate. Under the action of the guide member 10 and the guide groove, the drive sleeve 9 cannot rotate. During the rotation of the drive shaft 8, the drive sleeve 9 moves axially, thereby driving the second transmission gear 16 of the first rotary power source 15 to disengage from the first transmission gear 17. That is, when the second locking member 7 locks the first locking member 11, the second transmission gear 16 of the first rotary power source 15 and the first transmission gear 17 are in a disengaged state. At this time, when an impact force acts on the intercepting plate 2, the first rotary power source 15, the second transmission gear 16, and the first transmission gear 17 are not stressed, avoiding damage under the action of the impact force and increasing the service life of the access control. When the second locking member 7 does not lock the first locking member 11, the second transmission gear 16 and the first transmission gear 17 are in a meshed state, which is used to drive the intercepting plate 2 to rotate.

[0027] The above-mentioned technical features can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.
