[0002] In the inspection of pressure-bearing special equipment, accurate detection of the equipment's internal condition is crucial. Pressure-bearing special equipment typically has a complex structure and confined internal space, posing numerous challenges to inspection. Traditional inspection methods often struggle to directly observe subtle defects and damage within the equipment, leading to the failure to detect potential safety hazards in a timely manner and potentially causing serious accidents. Endoscopes, as an effective inspection tool, can penetrate deep into the equipment for observation; however, in practical use, due to the limited internal space, adjusting the position and angle of the endoscope probe is difficult, making it challenging to comprehensively and accurately obtain image information of various parts of the equipment's interior. Therefore, a specialized endoscope probe support rod for the inspection of pressure-bearing special equipment is needed to solve the problems of inconvenient position and angle adjustment and poor stability of the endoscope probe during use, thereby improving the efficiency and accuracy of pressure-bearing special equipment inspection and ensuring the safe operation of the equipment.

As an effective inspection tool, the endoscope can penetrate deep into the equipment for observation. However, in actual use, due to the limitations of internal space, it is difficult to adjust the position and angle of the endoscope probe, making it difficult to comprehensively and accurately obtain image information of various parts inside the equipment.

Endoscopes, as effective inspection tools, can penetrate deep into equipment for observation. However, in practical use, due to internal space limitations, adjusting the position and angle of the endoscope probe is difficult, making it challenging to comprehensively and accurately obtain image information from various parts of the equipment. This embodiment provides an endoscope probe support rod for inspecting pressure-bearing special equipment. Please refer to... Figures 1-6An embodiment provides an endoscope probe support rod for inspecting pressure-bearing special equipment, including a housing 1.

A receiving spring 20 is sleeved on the outer wall of the right section of the limiting connecting rod 13. A sliding ring 21 is fixedly connected to the outer end of the receiving spring 20. An extension rod 22 is fixedly connected to the outer end of the limiting connecting rod 13. The hinge rod 15 is hinged to... Adjust the middle section of the hinge rod 16, and the hinge rod 15 is circumferentially set on the outer wall of the limiting ring 14; the movable slide 19 is sleeved on the outer wall of the limiting rod 13; the sliding ring 21 is sleeved on the outer wall of the limiting rod 13; the left end of the outer shell 1 is fixedly installed with the outer shell 2, the left end of the outer shell 2 is rotatably connected with the connecting adapter 3, the left section of the connecting adapter 3 is fixedly installed with the connecting rod 4, the left end of the connecting rod 4 is fixedly installed with the end cap 5; the inner wall of the end cap 5 is threadedly connected with the threaded connecting rod 6, the outer wall of the threaded connecting rod 6 is rotatably connected with the rotating frame 7, the inner side of the rotating frame 7 is rotatably connected with the rotating connecting rod 8, the outer end of the rotating frame 7 is fixedly connected with the connecting slide 9, the inner wall of the connecting slide 9 is slidably connected with the fixed slide 10, the inner wall of the fixed slide 10 is fixedly installed with the fixed probe 11; the fixed probe 11 is fixedly installed on the inner wall of the outer shell 1.
[0025] Working Principle: The outer shell 1 serves as the main support structure for the entire support rod, providing space for the installation and protection of other internal components. The fixed connecting rod 12, fixedly installed on its right inner wall, connects and supports subsequent components. A limiting connecting rod 13 is fixed to the right end of the fixed connecting rod 12, and a limiting rotating ring 14 sleeved on the outer wall of the limiting connecting rod 13 can rotate around it. A hinge rod 15 is circumferentially hinged to the outer wall of the limiting rotating ring 14, and the hinge rod 15 is hinged to the middle section of the adjusting hinge rod 16. When the limiting rotating ring 14 rotates, it drives the hinge rod 15 to move, causing the adjusting hinge rod 16 to swing accordingly. The guide roller 17, rotatably connected to the inner wall of the outer end of the adjusting hinge rod 16, guides and reduces friction when the support rod moves inside the special equipment, allowing the support rod to move more smoothly in confined spaces. A sliding slide is hinged to the outer end of the adjusting hinge rod 16. The frame 19 and the movable slide 19 are fitted onto the outer wall of the limiting rod 13, allowing the movable slide 19 to slide axially along the limiting rod 13 during the swinging of the adjusting hinge rod 16. The limiting spring 18, fixedly connected to the bottom of the middle section of the adjusting hinge rod 16, limits the swing amplitude of the adjusting hinge rod 16 and provides a buffer, preventing the adjusting hinge rod 16 from swinging excessively and damaging other components.

The extension rod 22, fixedly connected to the outer end of the limiting rod 13, can further increase the length of the support rod to better penetrate into the special equipment.
[0026] The outer casing 2, fixedly installed at the left end of outer casing 1, provides an installation position for the connecting adapter 3; the connecting rod 4 fixedly installed on the left section of the connecting adapter 3 and the end cap 5 fixedly installed at the left end together form a rotating structure; the threaded connecting rod 6 threadedly connected to the inner wall of the end cap 5, when the threaded connecting rod 6 is rotated, causes the rotating frame 7 to move axially along the threaded connecting rod 6 due to the action of the thread; the rotating connecting rod 8 rotatably connected to the inner side of the rotating frame 7 allows the rotating frame 7 to rotate around the rotating connecting rod 8; the inner wall of the connecting slide 9 fixedly connected to the outer end of the rotating frame 7 is slidably connected to... The fixed slide 10, when the rotating frame 7 moves and rotates, will drive the connecting slide 9 to slide within the fixed slide 10, thereby adjusting the position and angle of the fixed probe 11; the fixed probe 11 is fixedly installed on the inner wall of the outer casing 1. Through the synergistic effect of the above components, the required detection information can be accurately obtained inside the pressure-bearing special equipment; in summary, the endoscope probe support rod, through the mutual cooperation between the various components, realizes the flexible adjustment of the probe position and angle, while having good stability and buffering performance, and can effectively meet the inspection needs of pressure-bearing special equipment.
