Detailed Description
The utility model provides a detection apparatus for dial plate rotation direction and number of turns for detect the rotation direction and the number of turns of trick lock dial plate.
The present invention will be described in detail with reference to the accompanying drawings and examples.
This embodiment provides a detection device of dial rotation direction and number of turns, includes: a dial rotating shaft 10 extending from the code lock shell, a light shielding sheet and a photoelectric sensor.
Specifically, as shown in fig. 1 and 2, the shade sheet adopts a fan-shaped shade sheet 2. As shown in fig. 4, the fan-shaped shade 2 is fixedly connected with the sleeve 4, or is of an integrated structure. The shaft sleeve 4 is in threaded connection with a dial rotating shaft 10 extending out of the code lock shell, and the fan-shaped light shading sheet 2 can be quickly installed on the dial rotating shaft 10 extending out of the code lock shell through the shaft sleeve 4.
As shown in fig. 1 and 2, the photoelectric sensor adopts three U-shaped correlation sensors 1 with U-shaped grooves, and the three U-shaped correlation sensors 1 are uniformly distributed around a rotating shaft 10 of the dial; the U-shaped correlation sensor is not in contact with the dial rotating shaft 10, and the opening of the U-shaped groove faces the dial rotating shaft 10. The fan-shaped shading sheet 2 sequentially passes through the U-shaped groove of the U-shaped correlation sensor 1 when rotating along with the dial rotating shaft 10.
Three U type correlation sensors 1 are installed in advance in preventing tearing open casing 3, prevent tearing open casing 3 fixed mounting on the trick lock casing. As shown in fig. 3 and 5, the tamper-proof housing 3 is a closed housing formed by fixedly connecting a bottom shell 31 and a top shell 32. During specific implementation, the top shell 32 and the bottom shell 31 are welded together through ultrasonic waves, so that the anti-disassembly shell 3 has anti-disassembly performance, and the possibility that the password is peeped through the change of the internal structure caused by the detachable shell is avoided.
Among them, three U-shaped correlation sensors 1 are mounted on the bottom case 31 in advance to ensure mutual position accuracy. The bottom shell 31 is provided with an installation opening with a shape corresponding to the fan-shaped shading sheet 2.
Through axle sleeve 4 and prevent tearing open casing 3 and can install this embodiment detection device on the trick lock fast, the step is as follows:
selecting the root of the dial rotating shaft 10 as an installation reference surface, and measuring the distance between the installed fan-shaped light shielding sheet 2 and the root of the dial rotating shaft 10 in advance to ensure that the installed fan-shaped light shielding sheet 2 can sequentially pass through the U-shaped grooves of the three U-shaped correlation sensors 1 when rotating;
the shaft sleeve 4 is screwed forwards from the root of the dial rotating shaft 10 until the sector shading sheet 2 is arranged at a pre-measured position;
rotating the dial rotating shaft 10 to enable the fan-shaped anti-dazzling screen 2 to be vertically upward, and then aligning the mounting opening of the bottom shell 31 with the fan-shaped anti-dazzling screen 2 to enable the anti-dismantling shell 3 to be sleeved outside the dial rotating shaft 10 and the fan-shaped anti-dazzling screen 2;
the tamper evident housing 3 is secured to the combination lock housing to complete the assembly.
The method for determining the rotating direction and the number of turns of the dial of the coded lock by the detection device of the embodiment is as follows:
the three U-shaped correlation sensors 1 are respectively numbered as A, B, C in the clockwise direction, and A is used as an origin sensor;
if the sequence that the fan-shaped light shielding sheet 2 sequentially passes through the three U-shaped correlation sensors 1 when rotating along with the dial rotating shaft 10 is detected to be A-B-C, the rotating direction of the dial rotating shaft 10 is considered to be clockwise rotation, and otherwise, the rotating direction is anticlockwise rotation; if the fan-shaped light shielding sheet 2 sequentially passes through the non-A-B-C-A or A-C-B-A sequence of the three U-shaped correlation sensors 1 when rotating along with the dial rotating shaft 10, the rotating direction of the dial rotating shaft 10 is considered to be changed midway;
when the fan-shaped light shielding sheet 2 rotates with the dial rotating shaft 10, the fan-shaped light shielding sheet rotates A, B, C three U-shaped correlation sensors 1 in sequence and rotates the A sensor again, the dial rotating shaft 10 is considered to rotate by one circle.
The fan-shaped shading sheet of the utility model sequentially passes through and triggers the three U-shaped correlation sensors when rotating along with the rotating shaft of the dial plate, and the rotating direction and the number of rotating turns of the rotating shaft of the dial plate are accurately judged by detecting the triggering sequence of the three U-shaped correlation sensors; the rotation angle of the rotating shaft of the dial plate cannot be accurately identified by detecting the triggering sequence of the three U-shaped correlation sensors, so that the possibility that the password of the coded lock is reversely pushed by the rotation angle is avoided, the password is ensured not to be monitored, and unknown danger is avoided.
Although the above is the detailed description of the present invention, the present invention is not limited thereto, and those skilled in the art can modify the principle of the present invention, therefore, various modifications performed according to the principle of the present invention should be understood as falling into the protection scope of the present invention.
