[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1-3 As shown, the rivet hole guide of this utility model embodiment includes a handle 1, a mounting block 2, a first positioning pin 3, and a second positioning pin 4. By mounting the device on the dustproof panel of the aircraft cargo hold using the first positioning pin 3 and the second positioning pin 4, the third through hole 23 can accurately determine the position of the second rivet hole, facilitating maintenance work.

[0029] Mounting block 2 is installed on one end of handle 1. Mounting block 2 has a first through hole 21, a second through hole 22, and a third through hole 23. The first through hole 21 and the second through hole 22 are used as mounting holes, and the third through hole 23 is used as a guide hole.

[0030] The first locating pin 3 is installed in the first through hole 21, and one end of the first locating pin 3 extends out into the mounting block 2 for installation in the screw hole of the aircraft cargo hold dust cover. In this way, the first locating pin 3 is used to initially position the mounting block 2, which facilitates the installation of the mounting block 2.

[0031] The second locating pin 4 is installed in the second through hole 22, and one end of the second locating pin 4 extends out into the mounting block 2 for installation in the first rivet hole of the aircraft cargo hold dustproof panel. In this way, the second locating pin 4 can perform secondary positioning of the mounting block 2, improving positioning accuracy.

[0032] In this embodiment, the third through hole 23 serves as a guide hole for the second rivet hole of the aircraft cargo hold dustproof plate, and the position of the second rivet hole can be determined through the guide hole.

[0033] Based on the above structural configuration, the first positioning pin 3 is installed in the first through hole 21, and one end of the first positioning pin 3 extends into the mounting block 2 for installation in the screw hole of the aircraft cargo compartment dustproof plate. The second positioning pin 4 is installed in the second through hole 22, and one end of the second positioning pin 4 extends into the mounting block 2 for installation in the first rivet hole of the aircraft cargo compartment dustproof plate. The third through hole 23 serves as a guide hole for the second rivet hole of the aircraft cargo compartment dustproof plate. The position of the second rivet hole can be determined through the guide hole, thereby enabling precise positioning of the rivet hole and achieving high positioning efficiency.

[0034] like Figure 1 As shown, in some embodiments, the handle 1 includes a grip 11 and a connecting rod 12, with the grip 11 connected to the mounting block 2 via the connecting rod 12. The grip 11 facilitates holding and use.

[0035] like Figure 3 As shown, in some embodiments, the thickness of the grip 11 is greater than the thickness of the connecting rod 12. Thus, the greater thickness of the grip 11 makes it more comfortable to hold, while the smaller thickness of the connecting rod 12 saves material.

[0036] like Figure 1 As shown, in some embodiments, the mounting block 2 has a mounting groove 24, and the end of the connecting rod 12 away from the handle 11 is disposed in the mounting groove 24. The connecting rod 12 is connected to the mounting block 2 by a rivet 5. In this way, the mounting structure between the connecting rod 12 and the mounting block 2 is stable.

[0037] In some embodiments, the depth of the mounting groove 24 is equal to the thickness of the connecting rod 12. The connecting rod 12 is installed in the mounting groove 24 without protruding from the surface of the mounting block 2, thus making the surface of the mounting block 2 regular.

[0038] like Figure 2 As shown, in some embodiments, the diameter of the first through hole 21 is larger than the diameter of the second through hole 22, and the diameter of the third through hole 23 is equal to the diameter of the second through hole 22. Furthermore, the second through hole 22 and the third through hole 23 are located on opposite sides of the first through hole 21.

[0039] In some embodiments, the centers of the first through hole 21, the second through hole 22, and the third through hole 23 are aligned on a straight line. This is to accommodate the installation requirements of the hollow nail assembly.

[0040] In some embodiments, the other end of the first positioning pin 3 extends into the mounting block 2, and the two ends of the first positioning pin 3 extending into the mounting block 2 are at the same height, making the mounting block 2 have a regular shape.

[0041] In some embodiments, the height of one end of the first positioning pin 3 extending out of the mounting block 2 is greater than the height of one end of the second positioning pin 4 extending out of the mounting block 2. This is advantageous because the first positioning pin 3 performs the initial installation positioning, and then the second positioning pin 4 performs the secondary positioning.

[0042] In some embodiments, the arrangement direction of the first through hole 21, the second through hole 22, and the third through hole 23 is perpendicular to the extension direction of the handle 1. This allows for easy adjustment of the positions of the first through hole 21, the second through hole 22, and the third through hole 23 by simply holding the handle 1, facilitating operation and use.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
