[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-5 As shown, this utility model provides a positioning box for a wheel bolt, including a positioning box 1. Positioning holes 2 are symmetrically opened at the four corners of the positioning box 1. An adjustment mechanism 3 is provided at the rear end of the positioning box 1. A base plate 4 is provided at the rear end of the adjustment mechanism 3. An installation mechanism 5 is provided at the rear end of the base plate 4.

[0025] The type and size of the positioning hole 2 can be adjusted according to the needs of the bolt.

[0026] In this solution, the use of positioning box 1 simplifies the installation process, allowing installers to quickly place the bolts in the correct position, reducing installation time and workload. At the same time, positioning box 1 can accurately position the bolts, ensuring a tight and accurate connection between the wheels and the landing gear, and ensuring that the wheels can work normally.

[0027] like Figures 3-4 As shown, the adjustment includes a mounting plate 31, the rear end of which is fixedly connected to the front end of the base plate 4. An adjustment bracket 32 ​​is fixedly installed on the front side of the mounting plate 31. Multiple sets of adjustment holes 33 are equidistantly opened on the upper and lower end faces of the adjustment bracket 32. Adjustment frames 34 are symmetrically opened on both sides of the front end of the adjustment bracket 32. Multiple sets of mounting holes 35 are equidistantly opened on one side of the adjustment frame 34, and multiple sets of mounting holes 36 are equidistantly opened on the other side of the adjustment frame 34. A fastening screw 37 is movably inserted into the interior of the mounting hole 36. A screw 38 is movably inserted into the interior of the mounting hole 35. A nut 39 is sleeved on the bottom end of the screw 38.

[0028] The adjusting bracket 32 ​​is H-shaped, and the bottom end of the screw 38 is connected to the internal thread of the nut 39.

[0029] The external part of the screw 38 is movably connected to the internal part of the mounting hole 35, and the adjustment bracket 34 is a bent irregular part.

[0030] In this solution, when a larger positioning box 1 needs to be accommodated, the screw 38 can be inserted into the relatively outer adjustment hole 33 on the adjustment bracket 32, thereby extending the adjustment bracket 34 outward by a certain distance; conversely, if the positioning box 1 is smaller, the screw 38 can be inserted into the inner adjustment hole 33, thereby achieving precise adaptation and installation of positioning boxes 1 of different sizes, and increasing their positioning range.

[0031] like Figures 1-5 As shown, the installation mechanism 5 includes a steel frame 51. The front end of the steel frame 51 is fixedly connected to the rear ends of the base plate 4. Mounting blocks 1 52 are symmetrically fixedly installed on both the left and right ends of the steel frame 51. Mounting block 2 53 is movably installed on one side of mounting block 1 52. Through holes 54 are symmetrically opened on both sides of mounting block 1 52 and mounting block 2 53. Screw 2 55 is movably inserted into the through hole 54. Locking block 56 is sleeved on the outside of screw 2 55.

[0032] The middle parts of both mounting block 1 (52) and mounting block 2 (53) are arc-shaped.

[0033] The external thread of screw 55 is connected to the internal thread of locking block 56.

[0034] In this solution, the efficient installation characteristics of the installation result enable the positioning box 1 to be accurately placed in the predetermined position, thereby ensuring that the bolts can be smoothly aligned with the screw holes on the wheel and landing gear during the subsequent wheel installation operation. This effectively improves the installation accuracy and efficiency, and provides a solid guarantee for the safe and reliable installation of the wheel.

[0035] The working principle of the positioning box for the wheel bolts of this machine will be explained in detail below.

[0036] like Figures 1-5As shown, when using the wheel bolt positioning box, the spacing between the two sets of adjustment brackets 34 is adjusted according to the requirements of the positioning box 1. This is achieved by loosening and removing the nut 39 from the screw, allowing the screw 38 to be inserted into different adjustment holes 33. The screw 38 is then inserted into the mounting hole 35, and the nut 39 is fitted onto and tightened, thus completing the position adjustment of the adjustment bracket 34. Simultaneously, the fastening screw 37, passing through the mounting hole 36, securely mounts the positioning box 1 to its rear end, facilitating its subsequent use. Furthermore, mounting blocks 52 and 53 are fitted onto the mounting rods at appropriate positions on the landing gear. Following the threaded engagement of bolt 2 55 through the through holes 54 of mounting block 1 52 and mounting block 2 53, the bolt 2 is tightly threaded into locking block 56. The strong locking effect between bolt 2 and locking block 56 effectively secures mounting block 1 52 and mounting block 2 53, preventing displacement or loosening during installation. During operation, before installing the wheel bolts, the positioning box 1 is placed in the appropriate mounting position, and the wheel bolts are then inserted through the positioning holes 2 of the positioning box 1. This ensures that when the wheel is installed onto components such as the landing gear, the bolts are smoothly aligned with the threaded holes on the wheel and landing gear, guaranteeing installation accuracy and efficiency.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
