[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0032] like Figures 1 to 7 As shown, an infrared video inspection mirror includes a display 2 and an infrared camera 3 mounted on a handle 1. A universal tube 4 is fixedly connected to the back of the display 2, and an adjustment component is connected to the other end of the universal tube 4. The end of the adjustment component away from the universal tube 4 is connected to the infrared camera 3. An extension component is connected to one end of the handle 1, and a limiting component is connected to the end of the extension component away from the handle 1. The universal tube 4 is connected to the limiting component. When the location to be inspected is in a narrow gap, a curved pipe, or a curved trench, the infrared camera 3 can be inserted into the inspection location through the universal tube 4. When the inspection location is relatively spacious, the length of the handle 1 can be extended through the extension component, and then the universal tube 4 is fixed to the handle 1 and the extension component through the limiting component, thereby fixing and supporting the infrared camera 3 at the end of the universal tube 4. This prevents the universal tube 4 and the infrared camera 3 at the end from shaking during inspection in a wide environment, improving the stability of the inspection process. The two inspection methods work together to greatly increase the inspection range of the infrared video inspection mirror and improve the applicability and practicality of the device.

[0033] In some embodiments, the adjustment assembly includes a fixed rod 5 and a micro motor 6. One end of the fixed rod 5 is fixedly connected to the end of the universal tube 4 away from the display 2. The micro motor 6 is embedded inside the end of the fixed rod 5 away from the universal tube 4. The output shaft of the micro motor 6 passes through the end of the fixed rod 5 away from the universal tube 4 and is connected to the infrared camera 3. When the infrared camera 3 at the end of the universal tube 4 moves to the inspection position, the micro motor 6 inside the fixed rod 5 can be activated to drive the infrared camera 3 to rotate, thereby increasing the inspection range of the infrared camera 3. It should be noted that the micro motor 6 is a reciprocating motor, rotating in the opposite direction after one revolution, thereby preventing the connecting wires of the infrared camera 3 from getting tangled and broken. Both the micro motor 6 and the connecting wires of the infrared camera 3 extend through the cavity of the universal tube 4 into the interior of the display 2 and are connected to the control circuit to provide power supply, control, signal transmission, and other functions.

[0034] In some embodiments, the extension assembly includes an extension rod 8 and an end rod 9. The extension rod 8 is located between the handle 1 and the end rod 9. Limiting holes 101 are provided at the ends of the handle 1 and the extension rod 8 near the end rod 9. Contraction holes 102 are provided on the side of the two limiting holes 101 away from the end rod 9. Anti-detachment blocks 10 are fixedly connected to the ends of the extension rod 8 and the end rod 9 near the handle 1. The two anti-detachment blocks 10 are slidably connected to the two contraction holes 102 respectively. The extension rod 8 and the end rod 9 are slidably connected to the two limiting holes 101 respectively. The end rod 9 and its bottom anti-detachment block 10 can extend outward from the contraction hole 102 inside the extension rod 8, and the extension rod 8 and its bottom anti-detachment block 10 can extend outward from the contraction hole 102 inside the handle 1, thereby achieving the purpose of extending the length of the handle 1. The anti-detachment block 10 can prevent the handle 1, the extension rod 8 and the end rod 9 from falling off each other during the extension process, improving the structural stability of the extension assembly. The limiting hole 101, in conjunction with the anti-detachment block 10, can prevent the extension rod 8 and the end rod 9 from shaking within the corresponding contraction hole 102, further improving the stability of the extension operation and reducing the shaking of the extended rod.

[0035] In some embodiments, annular positioning grooves 103 are provided in both limiting holes 101. Positioning rings 12 are fixedly connected to the outer walls of the extension rod 8 and the end rod 9 near the handle 1. The two positioning rings 12 are slidably connected to the two annular positioning grooves 103 respectively. When the extension rod 8 extends outward from the contraction hole 102, the positioning rings 12 are squeezed into the annular positioning grooves 103 as pulled, thereby fixing the extended extension rod 8 to the handle 1 and preventing the extension rod 8 from automatically retracting into the contraction hole 102 during use. The end rod 9 is positioned and fixed to the extension rod 8 in the same way. The positioning rings 12 can be deformed by compression to ensure that they can enter the annular positioning grooves 103 from the contraction hole 102 by compression and pulling. At the same time, when storing, they can enter the contraction hole 102 from the annular positioning grooves 103 by pulling and compression.

[0036] In some embodiments, the limiting assembly includes three U-shaped clamps 11, which are fixedly connected to the outer walls of the handle 1, the extension rod 8, and the end rod 9 at the ends away from the handle 1, respectively. The outer walls of the universal tube 4 and the fixing rod 5 are connected to the inner walls of the U-shaped clamps 11. The U-shaped clamps 11 are fixedly installed at the ends of the handle 1, the extension rod 8, and the end rod 9. When needed, the universal tube 4 can be snapped into the U-shaped clamps 11, and the fixing rod 5 can be snapped into the U-shaped clamps 11 of the end rod 9, thereby extending the infrared camera 3 to the end of the end rod 9 for infrared inspection operations.

[0037] In some embodiments, two infrared cameras 3 are provided. The output end of the micro motor 6 passes through the end of the fixing rod 5 away from the universal joint 4 and is fixedly connected to the camera housing 7. One infrared camera 3 is embedded in the end of the camera housing 7 away from the fixing rod 5, and the other infrared camera 3 is embedded in the side wall of the end of the camera housing 7 away from the fixing rod 5. The two infrared cameras 3 are fixed by the camera housing 7 and kept in a vertical installation position. When the micro motor 6 drives the camera housing 7 to rotate, the infrared camera 3 on the side can perform infrared inspection on the periphery of the inspection position, while the infrared camera 3 at the end can inspect the front end of the inspection position. The cooperation of the two infrared cameras 3 can more comprehensively inspect the location, reduce possible omissions in the inspection, and improve the infrared inspection effect.

[0038] In some embodiments, a sleeve 13 is fixedly connected to the back side of the display 2. The sleeve 13 is fitted onto the outside of the handle 1. A winding wheel 14 is fixedly connected to the side of the sleeve 13 away from the display 2. The end of the universal tube 4 closest to the display 2 is wound inside the winding wheel 14. The sleeve 13 facilitates the installation and removal of the display 2 from the handle 1. Simultaneously, during storage, the universal tube 4 can be coiled on the winding wheel 14, allowing for convenient storage of the display 2 and the universal tube 4 together, reducing the area occupied during storage.

[0039] In some embodiments, an infrared video inspection mirror includes a display 2 and an infrared camera 3 mounted on a handle 1. A universal tube 4 is fixedly connected to the back of the display 2, and an adjustment component is connected to the other end of the universal tube 4. The end of the adjustment component away from the universal tube 4 is connected to the infrared camera 3. An extension component is connected to one end of the handle 1, and a limiting component is connected to the end of the extension component away from the handle 1. The universal tube 4 is connected to the limiting component. When the location to be inspected is in a narrow gap, a curved pipe, or a curved trench, the infrared camera 3 can be inserted into the inspection location through the universal tube 4. When the inspection location is relatively spacious, the length of the handle 1 can be extended through the extension component, and then the universal tube 4 is fixed to the handle 1 and the extension component through the limiting component, thereby fixing and supporting the infrared camera 3 at the end of the universal tube 4. This prevents the universal tube 4 and the infrared camera 3 at the end from shaking during inspection in a wide environment, improving the stability of the inspection process. The two inspection methods work together to greatly increase the inspection range of the infrared video inspection mirror and improve the applicability and practicality of the device.
