[0014] Beneficial Effects

[0015] The present invention provides a probe-type cavity detection device, which has the following beneficial effects:

[0016] (1) The probe-type cavity detection device inserts the extension rod and the ball cover into the cavity to be detected, and the adjusting block is rotated to drive the rotating rod to rotate. By setting the forward thread and the reverse thread, the rotating rod will drive the two sets of threaded sleeves to move closer to or away from each other synchronously. The threaded sleeve drives the two sets of sliders to move through the connecting rod. At this time, the slider slides inside the slide groove, and the slider drives the two sets of arc plates to move away from each other. By setting the arc plate to an arc shape, the arc of the arc plate can be used to expand and squeeze the port of the cavity outward, so that the entire device can be fixed at the port of the cavity, thereby ensuring that the device is fixed at the position of the cavity port during the entire device detection process, ensuring stability during detection, and avoiding vibration or displacement of the entire device during the detection process that affects the entire detection result.

[0017] (2) The invasive cavity detection device can improve the comfort of the contact position when the arc plate contacts the skin of the cavity port by setting a sponge cover, thereby preventing the two sets of arc plates from moving to both sides and squeezing the user to cause pain and affect the detection experience.

[0018] (3) The invasive cavity detection device, by providing a spherical sleeve and a spherical block, enables the entire extension rod to swing at any angle inside the cavity through the movable connection of the spherical sleeve and the spherical block. After the fixing plate is fixed, the entire extension rod and the ball cover can be rotated and shaken inside the cavity by swinging the handle left and right to change the tilt angle, thereby increasing the detection area of ​​the entire device inside the cavity, improving the integrity of the entire detection, and increasing the flexibility of the entire device.

[0019] (4) The invasive cavity detection device is provided with an anti-slip cover so that when the entire device is in use, the user can increase the friction between the hand and the handle by holding the anti-slip cover, thereby improving the comfort of using the entire device.

[0020] (5) The invasive cavity detection device drives the adjustment shaft and the locking head forward by pushing the rotary button inward. At this time, the locking head is clamped in the interior of the locking sleeve. The rotary button drives the driving wheel to rotate. The driving wheel and the transmission belt drive the flip plate to flip and adjust the angle inside the ball cover, so that the image acquisition camera and the fill light can flip up and down inside the ball cover to fine-tune the shooting angle, thereby improving the accuracy and quality of the detection of the entire device.

[0021] (6) The invasive cavity detection device can be provided with a locking sleeve and a locking head. After the entire angle is adjusted, the locking head can be separated from the locking sleeve by pulling the rotating button outward, thereby preventing the rotating button from being touched by the outside world during the detection process, causing the flip plate inside the ball cover to vibrate, thereby ensuring the stability of the entire device during measurement.

[0022] (7) The invasive cavity detection device adjusts the angle of the entire flip plate so that the irradiated mirror corresponds to the inner wall of the cavity to be observed. At this time, the image of the inner wall of the cavity can be directly observed through the reflection of the irradiated mirror and the reflector, and the image acquisition of the image acquisition camera is electrically connected to the display screen, so that the image captured by the image acquisition camera can be observed through the display screen. Through the two observation methods, the display screen observation or mirror reflection observation can be selected according to the user's needs, thereby increasing the selectivity of the entire device when used.

[0041] Working principle of the present invention:

[0042] When in use, the extension rod 4 and the ball cover 5 are inserted into the cavity to be inspected, and the adjusting block 710 is rotated to drive the rotating rod 706 to rotate. By setting the forward thread 707 and the reverse thread 708, the rotating rod 706 will drive the two sets of threaded sleeves 709 to move closer to each other or away from each other synchronously. The threaded sleeve 709 drives the two sets of sliders 704 to move through the connecting rod. At this time, the slider 704 slides inside the slide groove 701, and the slider 704 drives the two sets of arc plates 702 to move away from each other. By setting the arc plate 702 to an arc, the arc of the arc plate 702 can be used to expand and squeeze the port of the cavity outward, so that the entire device can be fixed at the port of the cavity, thereby ensuring that the device is fixed at the position of the cavity port during the entire device detection process, ensuring stability during detection, and avoiding vibration or displacement of the entire device during the detection process to affect the entire detection result.

[0043] By providing the sponge cover 703, the arc plate 702 can improve the comfort of the contact position when contacting the skin of the cavity port, and prevent the two groups of arc plates 702 from moving to both sides to squeeze and cause pain to the user, thereby affecting the detection experience.

[0044] By providing the spherical sleeve 301 and the spherical block 302, the entire extension rod 4 can be swung at any angle inside the cavity through the movable connection between the spherical sleeve 301 and the spherical block 302. After the fixing plate 1 is fixed, the entire extension rod 4 and the ball cover 5 can be rotated and shaken inside the cavity by swinging the handle 604 left and right to change the tilt angle, thereby increasing the area of ​​the entire device inside the cavity, improving the integrity of the entire detection, and increasing the flexibility of the entire device.

[0045] By providing the anti-slip cover 605 , when the entire device is in use, the user can increase the friction between the hand and the handle 604 by holding the anti-slip cover 605 , thereby improving the comfort of using the entire device.

[0046] By pushing the rotating button 909 inward, the rotating button 909 drives the adjusting shaft 906 and the locking head 907 to move forward. At this time, the locking head 907 is clamped in the inside of the locking sleeve 905. By rotating the rotating button 909, the rotating button 909 drives the driving wheel 904 to rotate. The driving wheel 904 and the transmission belt 805 drive the flip plate 801 to flip and adjust the angle inside the ball cover 5, so that the image acquisition camera 803 and the fill light 804 can be flipped up and down inside the ball cover 5 to fine-tune the shooting angle, thereby improving the accuracy and quality of the detection of the entire device.

[0047] By setting the locking sleeve 905 and the locking head 907, after the entire angle is adjusted, the locking head 907 can be separated from the locking sleeve 905 by pulling the rotating button 909 outward, thereby preventing the rotating button 909 from being touched by the outside world during the detection process, causing the flip plate 801 inside the ball cover 5 to vibrate, thereby ensuring the stability of the entire device during measurement.

[0048] By adjusting the angle of the entire flip plate 801 so that the illuminating mirror 806 corresponds to the inner wall of the cavity that needs to be observed, the image of the inner wall of the cavity can be directly observed through the reflection of the illuminating mirror 806 and the reflector 603, and the image acquisition of the image acquisition camera 803 is electrically connected to the display screen 606, so that the image acquired by the image acquisition camera 803 can be observed through the display screen 606. Through these two observation methods, the display screen observation or mirror reflection observation can be selected according to the user's needs, thereby increasing the selectivity of the entire device when used.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
