A baffle is fixedly installed on the outer side of the support rod main body. A push rod is inserted into the interior of the support rod main body, and an adjusting component is fixedly installed at one end of the push rod. The adjusting component includes a round block. The round block is fixedly installed at one end of the push rod. A connecting block is fixedly installed on the outer side of the round block. A sliding groove adapted to the connecting block is opened in the interior of the support rod main body. A connecting sleeve is fixedly installed on the outer side of the connecting block. The connecting sleeve is sleeved on the outer side of the support rod main body. A hinge rod is hinged on the outer side of the connecting sleeve. A support component is fixedly installed on the outer side of the support rod main body. The other end of the hinge rod is hinged on the outer side of the support component. A positioning component is fixedly installed in the interior of the push rod.

[0004] As can be seen from the above, by setting the connecting sleeve and pulling the push rod, at this time, the push rod drives the round block to slide to a certain position inside the support rod main body. At the same time, the round block drives the connecting sleeve to slide on the outer side of the support rod main body through the connecting block. At this time, the connecting sleeve supports the whole support component through the hinge rod, so as to improve the unfolding efficiency of the support component by the unfolding of the support component, thereby improving the working efficiency of the device. However, this case still has the following deficiencies: When performing the endoscope inspection work of pressure-bearing special equipment, it is often necessary to inspect the inner cavities of different specifications and sizes. When the inner cavity of the pressure-bearing special equipment is not adaptable to the detection equipment, it is necessary to re-adjust to adapt to the inner cavity of the pressure-bearing special equipment, resulting in more cumbersome operations and unable to be installed and adjusted according to the actual situation.

[0005] Therefore, in view of the above problems, an endoscope probe support rod for the inspection of pressure-bearing special equipment is proposed. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-5 As shown, an endoscope probe support rod for pressure-bearing special equipment inspection includes a main body 1 and an adaptive moving component 2; the adaptive moving component 2 is installed with a fixed frame 21, and several mounting seats 22 are fixedly installed around the fixed frame 21. One side of several mounting seats 22 is respectively hinged with a first moving arm 24, one end of several first moving arms 24 is respectively movably installed with a first roller 23, a first spring 25 is fixedly installed on one side of the first moving arm 24, and the other side of the first spring 25 is fixedly installed with the fixed frame 21;

[0024] During operation, the whole is carried and supported by the fixing frame 21. When the first roller 23 contacts the inner cavity wall, pressure is exerted on the first spring 25 by the first movable arm 24. At this time, the first movable arm 24 rotates around the mounting seat 22 as the axis. When the first roller 23 is not subject to external force, it is restored to its initial position by relying on the first spring 25.

[0025] Furthermore, the main body 1 is provided with a support rod 11. One end of the support rod 11 is fixedly installed with a first universal joint 12. The other side of the first universal joint 12 is fixedly installed with a connecting shaft 13. The other end of the connecting shaft 13 is fixedly installed with a second universal joint 14. The other side of the second universal joint 14 is fixedly installed with a connecting rod 33.

[0026] During operation, the first universal joint 12 and the second universal joint 14 are components for realizing variable-angle power transmission and are used for positions where the axis direction needs to be changed. By installing them, it is beneficial to move the position of the connecting rod 33 and is conducive to adapting to the movement of the movable component 2 in the curved inner cavity.

[0027] Furthermore, three fixing seats 26 are fixedly installed on the inner wall of the fixing frame 21. One side of each of the three fixing seats 26 is hinged with a second movable arm 27. One end of each of the three second movable arms 27 is movably installed with a second roller 35.

[0028] During operation, by installing the fixing seats 26 on the fixing frame 21, it is beneficial to limit one end of the second movable arm 27 by the fixing seats 26. When the second roller 35 is subject to external force, the second movable arm 27 makes a circular movement around the hinge point.

[0029] Furthermore, one side of the second movable arm 27 is hinged with a connecting arm 28. The other end of the connecting arm 28 is hinged with a movable sleeve 29. The movable sleeve 29 penetrates and is movably installed on the connecting rod 33.

[0030] During operation, when the second movable arm 27 rotates, linkage is generated on the movable sleeve 29 through the connecting arm 28, causing the movable sleeve 29 to move correspondingly on the connecting rod 33.

[0031] Furthermore, one end of the connecting rod 33 is fixedly installed with a fixing rod 32. The fixing rod 32 is installed in the inner cavity of the fixing frame 21. One side of the fixing rod 32 is fixedly installed with a second spring 31. The other side of the second spring 31 is fixedly installed with the movable sleeve 29.

[0032] During operation, when the movable sleeve 29 slides on the connecting rod 33, the second spring 31 deforms under the action of external force and returns to its original state after the external force is removed. This is beneficial to enabling the outdoor position of the movable sleeve 29 to be adjusted correspondingly according to the inner cavity diameter.

[0033] Further, one end of the connecting rod 33 is fixedly installed with a fixed rod 32, and the other end of the connecting rod 33 is fixedly installed with an endoscope probe 34;

[0034] During operation, the installation of the endoscope probe 34 is beneficial to detecting the inner cavity of the pressure-bearing special equipment, and the installation of the fixed rod 32 is beneficial to bearing it.

[0035] Working principle: When performing the endoscope inspection of the pressure-bearing special equipment, the whole is placed in the inner cavity of the pressure-bearing special equipment. Since the inner cavity sizes of pressure-bearing special equipment of various specifications are inconsistent, when the whole is placed, the first roller 23 and the second roller 35 first come into contact with the inner cavity wall. When the inner cavity diameter is smaller than the unfolded state of the whole, the first roller 23 and the second roller 35 form a mutual acting force on the inner cavity wall, causing the first movable arm 24 to perform a circular movement with the mounting seat 22 as the axis. Under the influence of the acting force, the second roller 35 drives the connecting arm 28 through the second movable arm 27 to generate mechanical energy on the movable sleeve 29, so that the movable sleeve 29 slides correspondingly on the connecting rod 33 under the influence of the acting force. When the movable sleeve 29 makes a relative movement on the connecting rod 33, it compresses the second spring 31, causing the second spring 31 to continuously contract until the first roller 23 and the second roller 35 are in close contact with the inner cavity wall.

[0036] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
