[0030] like Figure 2 As shown, the utility model provides a fixture for an aircraft lifting ear, which is used to install a lifting ear body 4, and includes:

[0031] The clamping platform 1, the mounting portion 11 is provided with a positioning surface 112 for positioning the lifting ear body 4;

[0032] A positioning member 2, wherein the positioning member 2 is arranged to abut against the end surface of the mounting portion 11 and at least partially abut against the lifting ear body 4, so that the lifting ear body 4 is clamped between the positioning member 2 and the positioning surface 112;

[0033] The fastener 3 is connected between the positioning member 2 and the mounting portion 11 and is configured to enable the positioning member 2 and the mounting portion 11 to fasten the ear body 4 .

[0034] In this embodiment, see Figure 1The clamping platform 1 is fixed to the hanging fixture 5 in a detachable manner, and the hanging fixture 5 is fixed to the aircraft. The installation process of the lifting ear body 4 is as follows: first, slide the lifting ear body 4 into the mounting portion 11, and then place the positioning member 2 against the end of the mounting portion 11 to clamp the lifting ear body 4 on the clamping platform 1. At this time, the lifting ear body 4 is clamped between the positioning member 2 and the positioning surface 112. Then, the positioning member 2 and the mounting portion 11 are connected by the fastener 3, so that the lifting ear body 4 is locked on the clamping platform 1, so that the position of the lifting ear body 4 is relatively fixed. The clamp quickly positions the lifting ear body 4 through the positioning surface 112, and the positioning member 2 and the positioning surface 112 cooperate to accurately position the lifting ear body 4 on the mounting portion 11. Then, the positioning member 2 and the mounting portion 11 are connected by the fastener 3 to fasten the lifting ear body 4 to the clamping platform 1, thereby improving the accuracy and reliability of the installation position of the lifting ear body 4.

[0035] In one embodiment, see Figure 4 The end surface of the mounting portion 11 is provided with a fastening hole 113, and the positioning member 2 is provided with a through hole 21. When the positioning member 2 is against the end surface of the mounting portion 11, the through hole 21 is aligned with the fastening hole 113, and the fastener 3 is inserted through the through hole 21 and the fastening hole 113 to fasten the ear body 4 to the clamping platform 1. By providing the through hole 21 and the fastening hole 113, the fastener 3 can be quickly installed, which has the characteristics of simple structure and convenient operation.

[0036] In one embodiment, see Figure 4 The mounting portion 11 includes a fastening section 110, the fastening hole 113 is provided on the end surface of the fastening section 110, and the fastening section 110 is provided with a first guide cut surface 114 that is slidably matched with the lifting ear body 4.

The slide groove 413 is slidably plugged with the mounting portion 11. A second guide cut surface 414 is provided in the slide groove 413 to slidably cooperate with the first guide cut surface 114. The ear body 4 of this embodiment is installed on the mounting portion 11 through the fixing portion 41. The ear body 4 can be quickly installed by using a plug-in sliding method. The provision of the second guide cut surface 414 can further improve the installation efficiency of the ear body 4.

[0042] In one embodiment, see Figure 7 The fixing portion 41 includes a bottom plate 410, and vertical plates 411 are respectively provided on opposite sides of the bottom plate 410, and the two vertical plates 411 are vertically connected to a top plate 412. The bottom plate 410, the two vertical plates 411 and the top plate 412 enclose the slide groove 413, and the ear portion 42 is provided on the top plate 412. Specifically, the ear portion 42 and the fixing portion 41 are integrally formed, so that it is easy to produce and process.

[0043] In a specific embodiment, see, 2 and Figure 7, the length of the top plate 412 is less than that of the bottom plate 410, the top plate 412 is located in the middle, the positioning member 2 is configured to be inserted into the slide groove 413 from the first opening, the lower portion of the positioning member 2 abuts against the end surface of the mounting portion 11, and the upper portion of the positioning member 2 extends out of the slide groove 413 and at least partially abuts against the top plate 412. The positioning member 2 of this embodiment is placed in the slide groove 413, the lower portion of the positioning member 2 abuts against the end surface of the fastening section 110, and the upper portion of the positioning member 2 extends out of the slide groove 413 to abut against the top plate 412, thereby clamping the ear body 4, which facilitates the installation of the positioning member 2.
