Abstract
Description
Technical Field
[0001] This utility model relates to industrial endoscopes, and more particularly to an endoscope that is easy to adjust in direction. Background Technology
[0002] Industrial endoscopes are widely used inspection devices, typically for non-destructive testing or spatial exploration where personnel cannot easily access the area. When used for non-destructive testing, they can inspect and observe the internal structure of an object without disassembling or damaging it. However, existing flexible endoscopes are generally only suitable for short distances and for structures with only a single bend inside the object being inspected. In longer pipes, the probe tip initially turns under the traction of the guide wire. As the probe extends deeper into the pipe, the guiding force of the guide wire on the part of the insertion section furthest from the probe weakens, making it difficult to turn at bends in the pipe. This can easily lead to friction between the insertion section and the inner wall of the pipe, causing damage. Utility Model Content

Detailed Implementation
[0024] To more clearly illustrate the purpose, technical solution, and advantages of the embodiments of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description will be provided. Obviously, the described embodiments are some, but not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0025] Examples of embodiments of this utility model Figures 1 to 8As shown, an endoscope with easily adjustable orientation includes a front endoscope and a rear endoscope, both of which are flexible endoscopes. The front endoscope includes a front probe 1, a front insertion part 2, and a front operating handle 3 connected sequentially from end to end. Specifically, the front probe 1 is mounted at the front end of the front insertion part 2, and the rear end of the front insertion part 2 is mounted at the front end of the front operating handle 3. The front insertion part 2 uses a flexible tube structure, with no other components inside its tube. The traction wire, conductor, and optical fiber (not needed when using a front light source) connecting the front operating handle 3 and the front probe 1 are threaded through the tube wall of the front insertion part 2. The front operating handle 3 can be any existing industrial endoscope operating handle. The front insertion part 2 includes a front inner tube 20 whose rear end passes through the front operating handle 3 and a front operating handle 3. The front outer tube 21 at the front end of the handle 3 has a front through hole 30 at its tail end, which is coaxial with and connected to the front inner tube 20. In other words, the front outer tube 21 is mounted on the front side wall of the front operating handle 3. The front side wall of the front operating handle 3 has a handle through hole connecting the front outer tube 21 and the interior of the front operating handle 3. The front inner tube 20 is fitted inside the front outer tube 21, and its tail extends into the interior of the front operating handle 3 through the handle through hole and connects to the inner side wall at the tail end of the front operating handle 3. The front through hole 30 is located on the side wall at the rear end of the front operating handle 3, and it is connected to the front inner tube 20 and is on the same axis. The rear endoscope includes a rear probe 5, a rear insertion part 6, and a rear operating handle 7, connected sequentially from head to tail. The insertion part 6 includes a rear inner tube 60 that passes through the rear operating handle 7 at its tail end and a rear outer tube 61 connected to the front end of the rear operating handle 7. A rear sleeve 8 is provided at the front end of the rear operating handle 7 and fitted onto the tail end of the rear outer tube 61. The structure of the rear endoscope is the same as that of the front endoscope, except that the outer diameter of the rear insertion part 6 is smaller than the diameter of the front through hole 30 and the inner diameter of the front insertion part 2, and the rear sleeve 8 is installed on the front side wall of the rear operating handle 7. The rear sleeve 8 is made of rigid tubing and is fitted onto the tail end of the rear outer tube 61. This ensures that when the front and rear endoscopes are combined, there is a distance between them, facilitating the gripping and operation of the rear operating handle. At this time, both the front inner tube 20 and the rear inner tube 60 are flexible tubing. Both the outer tube 21 and the rear outer tube 61 include a front snake tube 210 and a rear hard tube 211. The front end of the snake tube 210 is connected to the rear end of the probe, and the rear end of the snake tube 210 is connected to the front end of the hard tube 211. The rear end of the hard tube 211 is connected to the front side of the operating handle, which facilitates the connection of the outer tube to the operating handle. At the same time, the snake tube 210 and the hard tube 211 are provided with a through-hole 22 for threading wires. The traction wire, wire, optical fiber, etc. used to connect the probe pass through the through-hole 22. The through-hole 22 is composed of the through holes on each segment of the snake bone on the snake tube 210 and the through holes on the hard tube 211. The inner tube is set to be in a hollow state so as not to affect the insertion of the rear insertion part 6 into the front insertion part 2.At this time, both the front outer tube 21 and the rear outer tube 61 are fitted with an outer sleeve 9, which protects the outer tube and prevents it from being damaged during use. The rear sleeve 8 can be detachably connected to the end of the front operating handle 3, and the rear insertion part 6 can pass through the front through hole 30 and be movably fitted inside the front insertion part 2. That is to say, after the front endoscope and the rear endoscope are connected, the rear insertion part 6 of the rear endoscope is inserted into the tube of the front insertion part 2 through the front through hole 30. Under the control of the rear operating handle 7, the rear insertion part 6 can make the front insertion part 2 turn with the rotation of the rear insertion part 6, without affecting the adjustment of the direction of the front endoscope itself. Consider a pipeline to be inspected, which is a horizontally laid-out L-shaped pipeline with a long distance in both the front-to-back and left-to-right directions. A vertical pipeline extends downwards from the right end in the left-to-right direction. When inspecting such a pipeline, the front operating handle 3 of the front endoscope can be used to adjust its rotation from the front-to-back direction to the left-to-right direction. As the front insertion part 2 penetrates deeper into the left-to-right pipeline, the rear operating handle 7 of the rear endoscope is used to adjust the rotation of the rear insertion part 6 from the front-to-back direction to the left-to-right direction. The rear insertion part 6 then synchronously adjusts the rear part of the front insertion part 2, ensuring sufficient force for the rotation adjustment. After horizontal adjustment, the front operating handle 3 of the front endoscope is used to adjust the front insertion part 2 vertically. This satisfies the need for multiple rotations of the insertion part in different directions over long distances in a pipeline, and solves the problems that often exist in existing industrial endoscopes when adjusting in multiple directions.
[0026] Further improvements, such as Figure 7 As shown, the rear operating handle 7 has a rear through hole 70 coaxial with and connected to the rear inner tube 60. This allows for the attachment and connection of another endoscope with the same structure to the rear endoscope when needed. The outer diameter of the insertion part of this new endoscope is smaller than the inner diameter of the rear insertion part 61 of the rear endoscope and the diameter of the rear through hole 70, enabling longer-distance endoscopic adjustment. Similarly, as... Figure 1 , Figure 4 and Figure 8 As shown, a front sleeve 4 is provided at the front end of the front operating handle 3 and sleeved on the tail of the front outer tube 21. This allows another endoscope with the same structure to be installed in front of the front endoscope when needed. The inner diameter of the insertion part of the installed endoscope is larger than the outer diameter of the front insertion part.
[0027] Further improvements, such as Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, for the connection structure between the rear sleeve 8 and the front operating handle 3, an extension arm 80 extends from the outer wall of the front end of the rear sleeve 8. The extension arm 80 can be two extension arms in the radial direction, or an annular extension arm around the circumference of the rear sleeve, or multiple extension arms spaced apart around the circumference of the rear sleeve 8. An extension arm through hole 81 is provided on the extension arm 80, and a threaded hole is provided at the tail end of the front operating handle 3. The rear sleeve 8 is detachably connected to the front operating handle 3 by a bolt passing through the extension arm through hole 81 and connected in the threaded hole. This allows for the connection between the rear endoscope and the front endoscope. When connecting, first insert the rear insertion part 6 into the front insertion part 2, aligning the extension arm through hole 81 with the threaded hole. Then, thread the bolt into the threaded hole to connect the rear sleeve 8 to the front operating handle 3, thus connecting the rear endoscope and the front endoscope. Disassembly is performed by reversing the steps. At this point, a sidewall groove can be provided on the outer side wall of the rear end of the front operating handle 3, with the threaded hole located at the bottom of the groove. After the rear sleeve 8 and the front operating handle 3 are connected, the extension arm 80 is positioned within the sidewall groove and does not protrude from the end face of the rear end of the front operating handle 3. When a front sleeve is also provided on the front operating handle 3, the front sleeve adopts the same structure as the rear sleeve.
[0028] Further improvements, such as Figure 3 As shown, for the installation structure of the tail end of the front inner tube 20 inside the front operating handle 3, the inner wall of the tail end of the front operating handle 3 is provided with a front groove 31 that matches and connects with the front inner tube 20. The front through hole 30 is located at the bottom of the groove 31. For example, an annular protrusion extends around the front through hole at the bottom of the groove 31, and then the front inner tube 20 is sleeved on the protrusion.
[0029] Further improvements, such as Figure 5 As shown, both the front probe 1 and the rear probe 5 include an annular housing 10, a camera 11 disposed on the front end face of the housing 10, and an illumination device 12. In other words, the front probe 1 and the rear probe 3 use probes with the same structure. The annular structure of the housing 10 facilitates underwater use by reducing drag. The illumination device 12 can be an LED lamp or a xenon lamp. The illumination device 12 includes a first LED lamp 120 disposed adjacent to the camera 11 and a second LED lamp 121 symmetrically disposed with respect to the first LED lamp 120. This creates a lighting effect in a defined direction, thereby enhancing the identification of surface three-dimensional morphology and defects.
[0030] Although the present invention has been described in detail above with general description and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
