[0038] The purpose of the present invention is to provide a cross-section geometric parameter measuring device to solve the problems existing in the above-mentioned prior art and effectively improve the measurement efficiency.

[0039] To make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0040] As Figures 1 - 18 shown, the present invention provides a cross-section geometric parameter measuring device, including a support rod 1, a vertical base 2 and an imaging measuring instrument. The first end of the support rod 1 is fixedly provided with a vertical base 2, and the imaging measuring instrument is fixedly arranged on the second end of the support rod 1. The imaging measuring instrument can measure the geometric parameters of the cross-section 3 of the object to be measured. One end face of the vertical base 2 away from the imaging measuring instrument is a contact surface, and the contact surface can be attached to the cross-section 3 of the object to be measured.

[0041] The cross-section geometric parameter measuring device provided by the present invention realizes the fixation of the relative position between the cross-section 3 of the object to be measured and the imaging measuring instrument by arranging the imaging measuring instrument on the support rod 1 and attaching the contact surface on the vertical base 2 to the cross-section 3 of the object to be measured, changing the distance between the imaging measuring instrument and the cross-section 3 of the object to be measured and the inclination angle of the imaging measuring instrument relative to the cross-section 3 of the object to be measured from variables to constants, reducing the difficulty of imaging measurement, improving the measurement accuracy, and effectively improving the measurement efficiency.

[0042] As a relatively preferred implementation manner of this embodiment, the contact surfaces on the vertical base 2 are all within the outer contour of the cross-section 3 of the object to be measured, that is, the entire end surface of the end of the vertical base 2 away from the imaging measuring instrument is all attached to the cross-section 3 of the object to be measured, and there is no part that extends beyond the cross-section 3 of the object to be measured and is suspended, which can effectively reduce the difficulty of imaging measurement.

[0043] As a relatively preferred implementation manner of this embodiment, the optical axis of the imaging measuring instrument is parallel to the center line of the support rod 1, and the contact surface is perpendicular to the center line of the support rod 1, which is used to ensure the vertical frontal imaging of the cross-section 3, can further reduce the difficulty of imaging measurement, improve the measurement accuracy, and improve the measurement efficiency.

[0044] As a relatively preferred implementation manner of this embodiment, the bottom of the vertical base 2 has a first limiting portion 4, and the top surface of the first limiting portion 4 can be attached to the bottom surface of the object to be measured, so as to prevent the vertical base 2 from tilting, rotating relatively or moving up and down with respect to the cross-section of the object to be measured, which is convenient for frontal imaging.

[0045] As a relatively preferred implementation manner of this embodiment, the bottom of the vertical base 2 has a second limiting portion 5, and the inner side surface of the second limiting portion 5 can be attached to the side surface of the object to be measured, so as to prevent the vertical base 2 from translating relatively with respect to the cross-section of the object to be measured, which is convenient for frontal imaging.

[0046] As a relatively preferred implementation manner of this embodiment, the vertical base 2 includes three fitting blocks 6, two of the fitting blocks 6 are on the first straight line, and the other fitting block 6 is outside the first straight line. The three fitting blocks 6 are fixedly connected by a connecting frame 7. The surfaces of the three fitting blocks 6 away from the imaging measuring instrument can be simultaneously attached to the cross-section 3 of the object to be measured. The structure is simple, which is convenient for manufacturing and use. It should be noted here that the number of the fitting blocks 6 is not limited to three, and the size of the fitting blocks 6 is not restricted, as long as it can be ensured that at least three points on the vertical base 2 that are not on the same straight line can be in contact with the cross-section 3 of the object to be measured simultaneously.

[0047] As a relatively preferred implementation manner of this embodiment, the connecting frame 7 is suspended, and the bottom of the connecting frame 7 is below the object to be measured, which can effectively reduce the occlusion of the cross-section 3 of the object to be measured and improve the imaging measurement accuracy.

[0048] As a relatively preferred implementation manner of this embodiment, the second end of the support rod 1 is provided with a handle 8 and a wrench 9. The handle 8 is used to be held, and the wrench 9 is communicatively connected to the imaging measuring instrument. Pulling the wrench 9 can control the imaging measuring instrument to work, which is convenient for operation.

[0049] As a relatively preferred embodiment of this embodiment, the imaging measuring instrument includes a camera 10, a processing main board 11, a display 12 and a battery. The camera 10 is fixedly arranged at the second end of the support rod 1. The processing main board 11 is communicatively connected to the camera 10 and the display 12. The battery is electrically connected to the camera 10, the processing main board 11 and the display 12. The battery can supply power to the camera 10, the processing main board 11 and the display 12. The processing main board 11 is used for image processing and completing geometric dimension calculation. The display 12 is used for displaying the measurement results.

[0050] As a relatively preferred embodiment of this embodiment, the camera 10, the processing main board 11 and the display 12 are integrally arranged. The embedded processing main board 11 and the display 12 are installed in the camera 10, with a compact structure and reduced space occupation.

[0051] As a relatively preferred embodiment of this embodiment, the camera 10, the processing main board 11 and the display 12 are separately arranged. The camera 10 is externally connected to the processing main board 11 and the display 12, which is convenient for flexible use. The camera 10 can be connected to an external computer or other devices with image processing capabilities by a cable for measurement.
