Description

Technical Field

[0002] In order to facilitate passage and improve passage efficiency, turnstile channels are set up at many inspection ports, such as border control ports and automatic train ticket gates. When the user's certificate is verified as legal, the turnstile channel door automatically opens to allow the user to pass. Compared with manual certificate verification, it is not necessary to invest a large amount of manpower in certificate verification, saving human resources and improving the efficiency of certificate verification. However, since there is no management personnel to verify the certificate, there may be users who want to tailgate or forcefully push open the turnstile channel door when the certificate is illegal or without certificate verification. Therefore, the turnstile channel door must have the function of preventing intentional break-in to prevent users from pushing open the turnstile channel door to rush through.

[0045] According to the above-mentioned two-way self-locking brake, the two-way self-locking brake is a component of a turnstile. The turnstile further includes a motor, a gate, a controller, and a monitoring unit.

[0046] Further, the present invention further includes a turnstile, which includes a monitoring unit, a controller, a gate, a motor, and a two-way self-locking brake. The controller is connected to the motor, the two-way self-locking brake, and the monitoring unit, and the self-locking brake is connected to the gate.

[0047] Furthermore, the monitoring unit includes, but is not limited to, an angle sensor and a monitor.

[0048] According to the above-mentioned turnstile with a two-way self-locking brake, its usage method is as follows: In a specific embodiment, the upper support seat, upper base, and first gear of the two-way self-locking brake are set as the first brake, and the lower support seat, lower base, and second gear are set as the second brake.

[0049] Power-off state: The first gear is engaged, the second gear is not engaged, and the motor is in a self-locking state.

[0050] When powered on and in normal use: The controller sends a power-on signal to the first brake. The first brake is powered on, and under the action of the electromagnet, the first gear disengages from the engaged state, and the two-way self-locking brake releases the self-locking and is in normal use.

[0051] When there is a malicious break-in: When the monitoring signal detects a malicious break-in situation, a signal is sent to the controller.

[0052] According to the above-mentioned two-way self-locking brake, the method for releasing the self-locking is as follows:

[0053] In the powered-on state, after the monitor confirms safety, a signal is sent to the controller. The controller sends a power-off signal to the second brake, the second brake releases the self-locking, and the two-way self-locking brake releases the self-locking.

[0054] In the power-off state, press the pressing end of the clamp. The hinged end rotates around the hinge point axis, applying an upward force to the upper base, causing the first gear to disengage from the engaged state and release the self-locking. When the external force is removed, under the action of the second elastic component, the clamp returns to its original state, and the two-way self-locking brake returns to the power-off self-locking state.

[0055] The beneficial effects of the present invention are as follows: Through the two-way self-locking brake of the present invention, self-locking in two modes of power-off state and powered-on use state can be achieved, effectively controlling the occurrence of malicious break-in events, maintaining a good and orderly inspection environment, saving labor costs, and improving the social image.
