[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0027] In one embodiment of this utility model, reference is made to Figure 1 As shown, this utility model discloses an inner diameter measuring instrument with wireless transmission function, comprising:

[0028] The probe is telescopically mounted inside the through hole of the mounting head. When the probe is inserted into the inner hole of the workpiece, the probe itself telescopically extends and automatically matches the inner wall of the workpiece, and finally abuts against the inner wall.

[0029] The digital display indicator 7 is connected to the mounting head and has a data communication interface. The digital display indicator 7 is electrically connected to the data communication interface, which facilitates data transmission between the digital display indicator 7 and the outside. One end of the probe abuts against the capacitive sensor inside the digital display indicator, and the other end of the probe extends out of the through hole of the mounting head. Once the probe is subjected to pressure and expands or contracts, the different expansion and contraction displacements of the probe can be transmitted to the capacitive sensor in real time. The capacitive sensor generates corresponding measurement values ​​based on the expansion and contraction displacements and transmits them to the display screen of the digital display indicator 7 in real time, so that the operator can obtain relevant data in real time.

[0030] The wireless transmitter 6 is fixed to the back of the digital display indicator 7 by screws. The wireless transmitter 6 also has a data cable and a connector on its exterior. The wireless transmitter 6 is electrically connected to the data communication interface; specifically, the data cable is connected to the data communication interface to acquire measurement values. The connector of the wireless transmitter 6 is used to wait for the plug of the trigger button 4 to be connected. The data communication interface transmits the measurement values ​​to the wireless transmitter 6 in real time. When the trigger button 4 is pressed, the wireless transmitter 6 sends the measurement values ​​to a remote receiving end for processing. The trigger button 4 can be implemented as a physical button, or it can be set as a virtual button; a virtual button helps prevent accidental touches.

[0031] In one embodiment of this utility model, reference is made to Figure 1 As shown, it also includes a gripping rod 2. The probe and the digital display indicator 7 are respectively fixedly connected to both ends of the gripping rod 2. The diameter of the gripping rod 2 matches the operator's palm. The gripping rod 2 separates the probe and the digital display indicator 7, which is beneficial for observing the digital display indicator 7 and also helps to expand the measuring radius of the probe. The gripping rod 2 has a wire inside, which is used to connect the probe and the digital display indicator 7. The gripping rod 2 is hollow inside and has a top rod that is movable. The mounting head has a rocker structure. One end of the probe abuts against the rocker, the rocker abuts against one end of the top rod, and the other end of the top rod abuts against the capacitive sensor of the digital display indicator. After the probe undergoes extension and retraction displacement, its extension and retraction displacement is transmitted to the capacitive sensor through the top rod and the rocker structure.

[0032] In one embodiment of this utility model, reference is made to Figure 1 As shown, the grip rod 2 is fitted with an anti-slip sleeve 3, which is made of soft, non-slip materials such as silicone to improve grip comfort. The anti-slip sleeve 3 has anti-slip texture to increase the friction between the palm and the grip rod 2, preventing damage caused by accidental detachment of the inner diameter gauge.

[0033] In one embodiment of this utility model, reference is made to Figure 2 As shown, the probe includes a first probe 1 and a second probe 8. The first probe 1 and the second probe 8 are coaxially mounted on the mounting head 1. When the probe is inserted into the inner hole of the workpiece, the ends of the first probe 1 and the second probe 8 respectively abut against two points in the inner hole of the workpiece, and the distance between the two points is measured.

[0034] In one embodiment of this utility model, reference is made to Figure 2 As shown, the axis of the first probe 1 is set perpendicular to the axis of the holding rod 2, so as to adjust the axes of the first probe 1 and the second probe 8 to be perpendicular to the inner wall of the workpiece hole, thereby improving the measurement accuracy.

[0035] In one embodiment of this utility model, reference is made to Figure 2As shown, the grip rod 2 and the digital display indicator 7 are connected by locking screws, which facilitates quick installation and removal of the digital display indicator 7.

[0036] In one embodiment of this utility model, reference is made to Figure 1 As shown, the anti-slip sleeve 3 and the trigger button 4 are located at the same end of the grip rod 2, and the anti-slip sleeve 3 is located between the trigger button 4 and the probe. The anti-slip sleeve 3 matches the palm, and the trigger button 4 matches the thumb, making gripping and triggering acquisition easier and more convenient.

[0037] In one embodiment of this utility model, reference is made to Figure 1 and 3 As shown, the device includes a mounting base 5, and the trigger button 4 is connected to the mounting base 5. The mounting base 5 can be adjusted along the length of the grip rod 2 to facilitate the adjustment of the position of the trigger button 4. The mounting base 5 is provided with a mounting groove 11 and two through holes 13. The two through holes 13 are coaxially arranged and both through holes 13 pass through the mounting groove 11. When the mounting base 5 is fitted onto the grip rod 2 through the mounting groove 11, the screw passes through the two through holes 13 and the nut is threaded. Tightening the nut reduces the width of the mounting groove 11, and the grip rod 2 is clamped between the two sides of the mounting groove 11 to complete the fixation.

[0038] In one embodiment of this utility model, reference is made to Figure 3 As shown, the mounting groove 11 is configured as a "U" shaped structure to match the structure of the grip rod 2. The inner wall of the mounting groove 11 is provided with an anti-slip part 12, which is configured as a toothed structure. The anti-slip part 12 is used to increase the friction between the mounting base 5 and the grip rod 2.

[0039] In one embodiment of this utility model, the digital display indicator 7 includes a battery, key input, display, microprocessor, capacitive sensor, and signal processing circuit.

[0040] The working principle of the inner diameter measuring instrument with wireless transmission function described in this utility model is as follows:

[0041] Hold the anti-slip sleeve 3 with your hand, place your thumb on the trigger button 4, ensure that the grip rod 2 is parallel to the inner hole of the workpiece, and insert the probe vertically into the inner hole of the workpiece. The first and second probes will undergo adaptive extension and retraction displacement due to the pressure of the workpiece. The amount of extension and retraction displacement of the probes is transmitted to the capacitive sensor of the digital display indicator in real time. The capacitive sensor converts the amount of extension and retraction displacement of the probes into the measured value of the inner diameter of the workpiece. After the probes stop retracting and the measured value output by the digital display indicator 7 remains unchanged, press the trigger button 4 again with your thumb. The wireless transmitter 6 will send the measured value to the remote receiving end. The system at the receiving end will automatically process the measured value and then move the probe to the next measurement point to continue the measurement.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
