[0020] Figure 1 It is a structural schematic diagram of the utility model.
[0021] Mark explanation:
[0022] 1 - lower lock shell 2 - lock tongue 3 - electromagnetic valve 4 - limiting block 5 - guide shaft
[0023] 6-Cam housing 7-Cam-shaped round lock 8-RFID module 9-Controller 10-Proximity switch Detailed Implementation
[0024] like Figure 1 As shown, this utility model is installed inside an anti-slip device box and specifically comprises a lower lock housing 1, a locking tongue 2, a solenoid valve 3, a limit block 4, a guide shaft 5, a cam housing 6, a cam-mounted round lock 7, an RFID module 8, a controller 9, and a proximity switch 10. The RFID module 8 is installed on the side of the anti-slip device box, and the proximity switch 10 is installed near the hinge between the top cover and the side of the anti-slip device box to detect whether the top cover is closed. The preferred model of the proximity switch is TL-Q5MC1-Z, the preferred model of the solenoid valve is the AU1253S-12C04 DC push-pull solenoid valve from Yaxin Electric, and the controller can be implemented using a single-chip microcomputer (preferably STC8051) or other embedded systems (preferably STM32F103).
[0025] In the open state, the upper lock shell without the upper cover is inside the lower lock shell 1. The front end of the latch 2 naturally penetrates into the through hole on the side wall of the lower lock shell 1 under the action of the spring. After the cover is closed, the upper lock shell of the upper cover enters the cavity of the lower lock shell 1. The front end of the latch 2 (in the preferred embodiment, the longitudinal section of the front end of the latch is a right triangle, with the right angle sides being the side wall and the bottom edge, respectively) naturally retracts. After the upper lock shell is fully inserted, the front end of the latch 1 automatically extends and locks the slot or through hole of the upper lock shell under the elastic force of the spring, thereby locking the lower lock shell 1 and the upper lock shell.
[0026] The rear end of the latch 2 is axially connected to the solenoid valve shaft via screws. A limit block 4 is installed below the solenoid valve 3. A guide shaft 5 inside the limit block 4 can only move horizontally along the internal track of the limit block 4. One side of the cam housing 6 has two holes for connecting and fixing the solenoid valve shaft and the guide shaft 5 respectively. The guide shaft 5 restricts the horizontal movement of the latch 2, cam housing 6, and solenoid valve shaft to prevent the latch 2 from jamming after axial rotation. Specifically, the limit block 4 and the solenoid valve 3 are fixed inside the door lock and will not be displaced. The guide shaft 5 and the shafts of the solenoid valve 3 (including the rear shaft, front shaft, and latch 1) are fixed on the cam housing 6, and the displacement of the three is synchronized, which can be regarded as a whole. The guide shaft 5 moves horizontally along the track inside the limit block 4, realizing the horizontal movement of the latch 2, cam housing 6, and solenoid valve shaft, preventing the latch 2 from jamming after axial rotation.
[0027] The cam housing 6 contains a cam with a cam-shaped round lock 7. The key unlocking and locking causes the cam to rotate, which in turn drives the cam housing 6 to move horizontally left and right.
[0028] The unlocking rotating cam drives the cam housing 6, and at the same time pulls the solenoid valve shaft and guide shaft 5 backward, so that the front end of the lock tongue 2 disengages from the lower lock housing 1, and the upper cover can be opened;
[0029] The RFID module 8 is connected with the controller 9 through a signal line, communicates with the controller 9 in an SPI protocol mode, and the controller 9 is connected with an electromagnetic valve control through a control line.
[0030] The authorized IC card is swiped at the RFID coil, the coil is inducted, the electromagnetic valve 3 is powered on, the push-pull electromagnetic valve is actuated to drive the electromagnetic valve shaft to move left as a whole, the locking tongue 2 is withdrawn from the through hole, and the upper cover can be opened.
[0031] The proximity switch 10 is installed near the hinge between the upper cover and the side of the anti-slip appliance box, transmits a signal to the controller 9, and monitors whether the upper cover is closed in real time.
[0032] Those skilled in the art can understand that all or part of the steps in the various methods of the above embodiments can be completed by instructing the relevant hardware through circuit setting, and the circuit setting can be completed by a single-chip microcomputer or other similar functional integrated chips, which is prior art. The core of the utility model is the overall structural layout of the system, and the local control method can be completed by programming of the prior art; the local module connection can be realized by the prior art. In the present application, the focus is on the design and linkage of the mechanical mechanism, and in the more preferred embodiment, the connection and electrical control of the electronic devices such as the RFID module, the controller and the proximity switch are also included. It should be noted that the role of the controller is only to output a power-on signal and upload a monitoring signal, which can be realized by the prior art, and should not be regarded as a limitation on the protection object of the utility model.
