[0002] To ensure flight safety, protect the health of passengers and crew, and avoid flight delays or interruptions caused by plumbing issues, aircraft maintenance personnel regularly inspect the galley's water pipes. During inspections, they focus on checking for deformation or cracks. If any deformation or cracks are found, they must be replaced promptly.

[0003] Currently, maintenance personnel mainly check whether water pipes are deformed by visual inspection. If slight deformation is found visually, a vernier caliper is needed for verification. During the visual inspection, maintenance personnel need to see the entire circumference of the water pipe, which can easily lead to missing inspection of a certain part of the water pipe due to eye fatigue or negligence. Moreover, when using a vernier caliper to verify the deformed part, it is necessary to move and rotate the vernier caliper along the axial direction of the water pipe multiple times to find the section with the largest deformation. This results in low inspection efficiency and the risk of missed inspections. Utility Model Content

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0028] like Figures 1 to 6As shown, a preferred embodiment of the aircraft pipeline inspection tool of the present invention includes a first half ring 1 and a second half ring 2. The first half ring 1 has a first connecting structure, and the second half ring 2 has a second connecting structure that can be connected to or detached from the first connecting structure. The first connecting structure is connected to the second connecting structure, so that the first half ring 1 and the second half ring 2 are paired to form a ring gauge for slidingly sleeved on the outside of the tube body to be inspected. When in use, the ring gauge is moved along the length direction of the tube body to be inspected, and the ring gauge will be stuck at the deformed part of the tube body to be inspected, so that whether the tube body to be inspected is deformed can be quickly and comprehensively detected, avoiding the missed detection in visual inspection; after the inspection is completed, the first connecting structure and the second connecting structure are detached, and the first half ring 1 and the second half ring 2 are separated from the outside of the tube body to be inspected.

[0029] Among them, there are many ways to set up the first connecting structure and the second connecting structure. In order to facilitate the quick connection of the first half ring 1 and the second half ring 2, the first connecting structure in this embodiment is a groove 12 set in the first half ring 1, and the groove 12 extends along the axial direction of the first half ring 1. The second connecting structure is a guide rail-shaped protrusion 22 arranged along the axial direction of the second half ring 2; the guide rail-shaped protrusion 22 is inserted into the groove 12, and the first half ring 1 and the second half ring 2 are aligned to form a ring gauge; the guide rail-shaped protrusion 22 is removed from the groove 12, and the first half ring 1 and the second half ring 2 are separated. During use, the first half ring 1 is first placed against one side of the tube to be inspected, and the second half ring 2 is then placed against the other side of the tube to be inspected. The second half ring 2 is then moved axially along the tube to be inspected, and the guide rail-shaped protrusion 22 is inserted into the slot 12 to connect the first half ring 1 and the second half ring 2. If the slot 12 is a T-slot or a dovetail slot, the slot 12 can be provided only on one side of the first half ring 1, and the guide rail-shaped protrusion 22 can be provided only on one side of the second half ring 2. In this embodiment, to ensure the firmness of the connection between the first half ring 1 and the second half ring 2, two slots 12 are provided, and the two slots 12 are symmetrically arranged on both sides of the first half ring 1; two guide rail-shaped protrusions 22 are provided, and the two guide rail-shaped protrusions 22 are symmetrically arranged on both sides of the second half ring 2. In other embodiments of the present invention, the first connecting structure can be provided as a threaded hole 13, and the second connecting structure can be provided as a connecting screw passing through the second half ring 2.

[0030] To prevent axial misalignment after the first half ring 1 and the second half ring 2 are connected, in this embodiment, a threaded hole 13 is provided in the wall of the clamping slot 12. A locking member 3 is threadedly connected to the threaded hole 13. The threaded end of the locking member 3 abuts against the outer side of the guide rail-shaped protrusion 22 inserted into the clamping slot 12. Specifically, the locking member 3 is provided in the wall of one of the two clamping slots 12.

[0031] To ensure that the locking member 3 securely locks the guide rail-shaped protrusion 22, in this embodiment, a positioning groove 23 is provided on the outer side of the guide rail-shaped protrusion 22, and the threaded end of the locking member 3 is inserted into the positioning groove 23. Specifically, the positioning groove 23 is a circular through hole or a blind hole. After the end of the locking member 3 is inserted into the positioning groove 23, it can cause the first half ring 1 and the second half ring 2 to move relative to each other axially.

[0032] In this embodiment, the locking member 3 includes a threaded section 31 and a gripping section 32. The threaded section 31 is threadedly assembled into the threaded hole 13, while the gripping section 32 protrudes beyond the first half ring 1 and is intended to be grasped by a human hand. Specifically, the ring gauge formed after the first half ring 1 and the second half ring 2 are assembled is relatively small, making it difficult for an operator to grasp. In this embodiment, the operator can grasp the gripping section while sliding the assembled ring gauge from the first half ring 1 and the second half ring 2, facilitating inspection work.

[0033] Furthermore, the diameter of the gripping section 32 is larger than the diameter of the threaded section 31, and the end of the gripping section 32 closest to the threaded section 31 abuts against the outer wall of the slot 12. Specifically, the threaded end is located inside the first half ring 1 and the second half ring 2, so the operator cannot directly visually determine whether the threaded section 31 has been inserted into the positioning groove 23. Setting the diameter of the gripping section 32 larger than the threaded section 31 not only makes it easier for the operator to grip, but also when the end of the gripping section 32 abuts against the outer wall of the slot 12, it indicates that the end of the threaded section 31 has been inserted into the positioning groove 23, making it easier for the operator to clearly determine whether the locking member 3 is locked in place.

[0034] To further facilitate the operator's grip, in this embodiment, the outer peripheral side of the gripping section is a knurled surface.

[0035] In this embodiment, if the ring gauge fits too tightly with the tube to be inspected, it will be difficult to move the ring gauge. If the ring gauge fits too loosely with the tube to be inspected, the detection accuracy will be too low. In this embodiment, the clearance between the ring gauge and the tube to be inspected is greater than or equal to 0.1 mm and less than or equal to 0.3 mm. This not only ensures the detection accuracy, but also ensures that the ring gauge can slide smoothly along the non-deformed tube to be inspected. Specifically, the first half ring 1 has a first semicircular hole 11, and the second half ring 2 has a second semicircular hole 21. After the first half ring 1 and the second half ring 2 are aligned, the first semicircular hole 11 and the second semicircular hole 21 form a ring gauge hole. The diameter of the ring gauge hole differs from the diameter of the tube to be inspected by only greater than or equal to 0.1 mm and less than or equal to 0.3 mm.

[0036] In this embodiment, the first half ring 1 and the second half ring 2 are both made of resin material. The resin material has high wear resistance and a small thermal expansion coefficient. Changes in ambient temperature have little effect on the accuracy of the first half ring 1 and the second half ring 2, ensuring the scope of use of the aircraft pipeline inspection tool of this embodiment.

[0037] The method of using the aircraft pipeline inspection tool of this embodiment is as follows:

[0038] First, place the first half ring 1 against the outside of the tube to be inspected so that the tube to be inspected is located in the first semicircular hole 11. Then, the second half ring 2 is relatively staggered with the first half ring 1 up and down and the second half ring 2 is placed against the outside of the tube to be inspected. Then, move the second half ring 2 downward and insert the guide rail-shaped protrusions 22 on both sides of the second semicircular hole 21 into the corresponding slots 12 respectively. Then, screw the gripping section 32 until the end of the gripping section 32 abuts against the outside of the first half ring 1. At this time, it indicates that the threaded section 31 has been inserted into the positioning groove 23. Then, hold the gripping section 32 by hand. , slide the aircraft pipeline inspection tool of this embodiment along the length direction of the tube to be inspected. If the aircraft pipeline inspection tool of this embodiment can slide smoothly, it means that the tube to be inspected is not deformed. If the aircraft pipeline inspection tool of this embodiment is stuck, it means that the tube to be inspected is deformed. After the inspection is completed, first reversely rotate the gripping section 32 to unscrew the threaded section 31 from the positioning groove 23, and then push the gripping section 32 downward or upward to separate the first half ring 1 and the second half ring 2, so that the aircraft pipeline inspection tool of the present invention can be removed from the outside of the tube to be inspected.

[0039] In summary, the aircraft pipeline inspection tool of the present invention includes a first half ring 1 and a second half ring 2. The first half ring 1 has a first connecting structure, and the second half ring 2 has a second connecting structure that can be connected to or detached from the first connecting structure. The first connecting structure is connected to the second connecting structure, so that the first half ring 1 and the second half ring 2 are paired to form a ring gauge for slidingly sleeved on the outside of the tube body to be inspected. The ring gauge is moved along the length direction of the tube body to be inspected. The ring gauge will be stuck at the deformed part of the tube body to be inspected, so that it can quickly and comprehensively detect whether the tube body to be inspected is deformed, avoiding the missed detection in visual inspection; after the inspection is completed, the first connecting structure and the second connecting structure are detached, and the first half ring 1 and the second half ring 2 are separated from the outside of the tube body to be inspected; the setting of the locking member 3 not only facilitates the operation of the operator, but also ensures the stable connection between the first half ring 1 and the second half ring 2, greatly improves the inspection efficiency, and ensures the inspection accuracy.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
