The chip is used for detecting and recording on-off information of a detection circuit connected with the electronic tag. The antenna is used for carrying out wireless data exchange with an external electronic tag reader so as to transmit the on-off information of the detection circuit stored in the chip to the electronic tag reader.

In the schematic view of the apparatus for detecting relative rotation between components shown in fig. 1, the first nest 12 and the second nest 21 are respectively fixed to the relatively rotatable components to be detected in a nesting manner, and when the relatively rotatable components to be detected are initially fastened, the cutting member 50 is inserted into the groove 11 of the end face of the first nest 12 relative to the second nest 21. When the parts to be detected rotate relatively, the cutting member 50 cuts the metal detection line 41, which results in the open circuit of the closed circuit formed by the metal detection line 41 and the electronic tag 30. When the electronic tag 30 can detect the occurrence of the open circuit of the closed circuit, it can be known that the component to be detected rotates to some extent to cause the open circuit of the closed circuit, and at the same time, the open circuit information of the closed circuit is recorded in the chip of the electronic tag 30.

The device is simple to use, and can quickly and effectively judge the relative rotation of the components.

In one embodiment, at least two metal wires, such as the metal detection wire 41 and the metal detection wire 42 in fig. 2, are contained in the first detection section 10;

each electronic tag 30 is respectively connected with the metal detection line 41 and the metal detection line 42 to form a closed circuit, and a plurality of electronic tags and the corresponding

metal detection lines

41 and 42 can form a plurality of closed circuits;

at least one electronic tag 30 is distributed on the opposite end faces of the first detection part 10 and the second detection part 20 according to a preset angle;

the cutting member 50 is interposed between the at least two

metal detecting lines

41 and 42, and cuts at least one of the at least two

metal detecting lines

41 and 42 when the two relatively rotatable members are relatively rotated.

The grooves 11 are arranged in a circular ring shape on the end surface of the first nest portion 12 so that when relative rotation occurs between the members to be inspected, the cutting members 50 inserted into the grooves 11 are rotated therewith to cut off the metal detecting lines 41 and/or the metal detecting lines 42 provided across the grooves.

In the following embodiments, the initial position of the cutting element 50 may be defined as a 0 degree position, for example.

For example, as shown in fig. 2, on the end faces of the first detection section 10 and the second detection section 20 opposed to each other, there are provided, on average, 4 electronic tags 30 and four sets of

metal detection lines

41 and 42 constituting 4 independent closed circuits with which the four sets of closed circuits are provided at positions of 0 degrees, 90 degrees, 180 degrees, and 270 degrees of the circumference of the end faces of the first detection section 10 and the second detection section 20 opposed to each other, respectively.

The initial position of the cutting component 50 is between two metal detection lines of the closed circuit at the 0-degree position, when the components to be detected rotate relatively, the cutting component 50 cuts off the metal detection line 42 in the clockwise direction, and at this time, the electronic tag 30 can judge that the components to be detected rotate 0-90 degrees in the clockwise direction. When the cutting component 50 cuts off the metal detection line 41 in the counterclockwise direction, the electronic tag 30 can determine that 0 can determine that the component to be detected rotates by 0 to 90 degrees in the counterclockwise direction.

When the part to be detected rotates to a greater extent, the

metal detection lines

41 and 42 located at 90 degrees are cut off by the cutting part 50, and then the electronic tag 30 can determine that the part to be detected rotates by 0-180 degrees in the clockwise direction. If the

metal detection lines

41 and 42 at the 270 degree position are cut by the cutting member 50, the electronic tag 30 can determine that the member to be detected rotates 0-180 degrees in the counterclockwise direction.

By analogy, the electronic tag 30 can determine the angle range and the rotation direction of the part to be detected relative to rotation according to the on-off information of the closed circuit caused by the fact that the metal detection lines at different positions are cut off.

the cutting member 50 is interposed between the at least two

metal detecting wires

41 and 42, and cuts off the at least one metal detecting wire when the two relatively rotatable members are relatively rotated.

For example, as shown in fig. 3, 1 electronic tag 30, one metal detection line 41 fixed at a position of 0 degree on the opposite end faces of the first detection portion 10 and the second detection portion 20, and 12 metal detection lines 42 are used to form 12 closed circuits, which are evenly distributed on the opposite end faces of the first detection portion 10 and the second detection portion 20. The end faces were divided into 12 portions each at 30 degrees. The cutting member 50 is initially positioned between the

metal detecting wires

41 and 42 at the 0 degree position. When the electronic tag 30 detects that the closed circuit at the position of 30 degrees clockwise is opened, it can be determined that the angular range of the relative rotation between the components is between 0 and 30 degrees in the clockwise direction. When the electronic tag 30 detects that the closed circuit located at the position of 60 degrees clockwise is opened, it can be determined that the angle range of the relative rotation between the components is between 0 and 60 degrees in the clockwise direction, and so on, the present embodiment can more accurately determine the angle and the direction of the rotation between the components.

The plurality of electronic tags may respectively form a plurality of closed circuits, or one electronic tag may form a plurality of closed circuits. It is conceivable that the more the number of closed circuits, the more accurate the determined rotation angle between the parts and, at the same time, the more complicated the circuit.
