Abstract
Description
Technical Field
[0001] This utility model relates to the field of endoscope technology, and in particular to a convenient tube clamping device for endoscopic testing. Background Technology
[0002] The insertion tube is a core component of industrial endoscopes, used for signal transmission, probe guidance, protection of imaging elements, and enabling flexible operation and multifunctional integration. It is crucial for ensuring inspection efficiency and equipment stability. In the field of engine inspection, the application of traditional industrial endoscopes is subject to numerous limitations. On the one hand, different types of engines have varying inspection requirements, making it difficult for traditional endoscopes to adapt to diverse inspection scenarios. On the other hand, engine inspection environments are extremely complex, often involving extreme conditions such as high temperature, high pressure, and vibration. Furthermore, oil and chemicals inside the engine can easily adhere to the endoscope's insertion tube, altering its material properties and making it more susceptible to deformation or damage. In addition, the compact internal structure and limited space of an engine make the insertion tube highly vulnerable to collisions or friction with surrounding components during operation, and it may even be damaged or cut by internal rotating parts. These factors not only reduce inspection efficiency and accuracy but also significantly increase the risk of equipment damage.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a convenient tube clamping device for endoscopic inspection, so as to solve the problems mentioned in the background art.
[0005] The technical solution of this utility model is as follows: A convenient tube clamping device for endoscopic examination is provided, comprising: a guide tube, a locking nut, a clamping element, an O-ring, a bushing slide, a bushing spring, a clamping sleeve, a locking bead, and a stop ring; the outer side of the clamping sleeve is provided with several bead holes, sliding grooves, and stop grooves; the bead holes and stop grooves are disposed in the sliding grooves; the locking bead is disposed at the bead holes; the bushing slide and bushing spring are sleeved on the sliding grooves; a pressure ring is provided on the inner side of the bushing slide; one side of the pressure ring is a guide slope, and the other side is an abutment surface; the two ends of the bushing spring abut against the side wall and the abutment surface of the sliding groove, respectively; the stop ring is inserted into the stop groove and disposed on the inner side of the bushing slide; the locking bead is disposed at the stop ring. Between the bushing spring and the stop ring, the pressure ring is disposed between the bushing spring and the stop ring; the clamping member includes: an extension portion and a locking ring connected to the extension portion; the clamping member has a tube hole that passes through the extension portion and the locking ring; the outer surface of the extension portion has a beaded groove; the inner side of the clamping sleeve has a top-fitting ring; the extension portion extends into the clamping sleeve; the O-ring is disposed between the extension portion and the top-fitting ring; the beaded holes pass through the clamping sleeve; a plurality of the beaded holes form an annulus in the clamping sleeve and surround the beaded groove; one end of the guide tube has an annular ear plate; the guide tube passes through the locking nut; the locking nut is connected to the locking ring and clamps the annular ear plate between the locking nut and the locking ring; the front end of the guide tube is a flexible tube.
[0006] In application, the endoscope insertion tube is passed through the clamping sleeve, clamping element, locking nut, and guide tube. Then, the locking nut is connected to the locking ring, and the bushing slide is moved so that the locking ball is pressed by the pressure ring, pressing part of the locking ball into the ball ring groove, thereby firmly locking the insertion part. This also firmly clamps the insertion tube with the O-ring. The guide tube design effectively isolates the external environment, providing reliable protection for the insertion tube and preventing it from being damaged by external factors.
[0007] The endoscope insertion tube passes through the inner hole of the guide tube, isolating the insertion tube from the external environment. This invention enables the protection and movement of the endoscope insertion tube, and is particularly suitable for environments with complex internal structures and confined spaces. This method significantly improves testing efficiency, reduces operational difficulty, and minimizes potential damage to the endoscope equipment caused by environmental factors, thereby extending the equipment's lifespan and enhancing the reliability and safety of testing operations.
[0008] Guide tubes of varying lengths, diameters, and flexibility are used to adapt to different working conditions, and O-rings are precisely selected to match the endoscope's insertion tube. This close integration of the endoscope and this invention significantly improves the endoscope's testing efficiency and ease of operation in complex environments. The guide tube design effectively isolates the external environment, providing reliable protection for the insertion tube and preventing external damage. The O-ring, combined with locking beads, bushing slides, and bushing springs, achieves a stable and reliable clamping effect, eliminating the risk of the endoscope's insertion tube loosening or falling out. The application of this invention directly extends the endoscope's service life, significantly improves the reliability and safety of testing, and reduces operational difficulty and maintenance costs, demonstrating significant practical value and innovation.
[0009] Furthermore, the portable tube clamping device for endoscopic examination further includes a plastic gasket, which is clamped between the annular lug and the locking nut. The plastic gasket is preferably a silicone gasket, which provides cushioning between the annular lug and the locking nut.
[0010] Furthermore, the locking nut is provided with an external thread, and the locking ring is provided with an internal thread, the internal thread engaging with the external thread.
[0011] Furthermore, the inner side of the clamping sleeve is provided with an anti-bend groove, which communicates with the tube hole. The anti-bend groove is used to prevent the endoscope insertion tube from bending at an excessive angle, thereby reducing the probability of breakage.
[0012] Furthermore, the surface of the top connecting ring that does not contact the O-ring is a bevel, which can prevent the right angle from directly pressing against the insertion tube of the endoscope.
[0013] Furthermore, the outer surface of the bushing slide is provided with anti-slip grooves.
[0014] Furthermore, an anti-ejection ring is provided on the outer side of the clamping sleeve, and the anti-ejection ring is located at one end of the sliding groove. The anti-ejection ring is used to prevent the bushing spring from ejecting.
[0015] Furthermore, the opening at one end of the guide tube, where the annular ear plate is located, is a flared opening. This flared opening facilitates the insertion of the guide tube into the gold guide tube.
[0016] Furthermore, the locking bead is made of any one of iron, iron alloy, copper, copper alloy, aluminum, aluminum alloy, titanium, or titanium alloy, preferably stainless steel.
[0017] Using the above solution, this utility model provides a convenient tube clamping device for endoscopic inspection. Because the front end of the guide tube is flexible, it can be bent, thus guiding the insertion tube into various types of narrow, twisted, or inaccessible spaces for inspection. The guide tube can be quickly installed or removed and can be replaced with other curved guide tubes to assist in inspection, depending on the inspection conditions. When used in conjunction with this utility model, especially in the field of aero-engines, this device enables the probe to quickly and accurately reach the inspection area, saving significant time in engine maintenance while also preventing direct collisions or friction with surrounding components, and significantly extending the service life of the endoscope.
