The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0035] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0036] As described in the background technology, in an aviation chassis, module boxes with different functions have different structures due to their different functions, and different structures lead to different contact positions of the locking strips during the installation process. When using traditional locking strips to lock and install the module boxes, insufficient constraints relying on the structural form become a thorny problem. At this time, it is necessary to consider adding parts or modifying the structural form of the module box or even redesigning the chassis slot to increase the installation fulcrum or reconstruct the installation position. Although this can also solve the problems encountered during the installation process, it will greatly increase the use cost of the product and even affect the functional structure of the product.

[0037] Based on the above reasons, Figure 1-Figure 5As shown, this embodiment provides a three-way locking strip, comprising a mounting shaft, a locking portion, a pushing portion and a driving portion, wherein the locking portion and the driving portion are mounted on the mounting shaft, and the locking portion and the driving portion are matched through an inclined surface;

[0038] The locking part includes two or three locking strips, and the locking strips can slide outward from the mounting shaft as a whole, and each locking strip has a different extension direction; the locking strips are matched with each other through inclined surfaces;

[0039] The pushing part is in contact with the driving part, wherein the driving part is installed at one end of the installation shaft to drive the pushing part to move axially along the installation shaft, and the pushing part cooperates with one or two locking strips through an inclined surface.

[0040] The three-way locking strip described in the above technical features can be locked in three directions after installation, and the three locking parts are matched with inclined surfaces. Under the drive of the driving part, the pushing part pushes the locking part, which can realize the linkage of the three locking parts and achieve quick locking or unlocking.

[0041] Exemplarily, the locking portion includes a first locking portion 400, a second locking portion 500 and a third locking portion 600, and the three locking portions extend in different directions, such as Figure 1 As shown, the first locking part extends upward, the second locking part extends rightward, and the third locking part extends leftward. The three directions are different from each other, and the left and right directions are parallel and perpendicular to the top. The pushing part includes a first push block 300 and a second push block 700. The first push block 300 and the second push block 700 both use inclined surfaces to cooperate with the locking part. The first push block 300 is installed at one end of the installation shaft and close to the threaded part 101, and the second push block is installed at the other end of the installation shaft and contacts the limit part 102. The inclined surface connecting the first push block and the locking part is arranged parallel to the inclined surface connecting the second push block and the locking part.

[0042] The second locking portion 500 is mounted on the mounting shaft 100. Figure 7 and Figure 1 As shown, the second locking part 500 includes a second locking plate 501, on which a first driving part A502 and a second driving part A503 are opened, wherein the first driving part A502 has an inclined surface that matches the inclined surface of the first push block.

[0043] The first locking portion 400 is mounted on the mounting shaft 100. Figure 6 and Figure 1As shown, the first locking part includes a first locking plate 401, on which a first driving part B403 and a second driving part B402 are provided, wherein the first driving part B403 has an inclined surface that matches the inclined surface of the first driving part A502; and the second driving part B402 has an inclined surface that matches the inclined surface of the second driving part A503.

[0044] The third locking portion 600 is mounted on the mounting shaft 100. Figure 8 and Figure 1 As shown, the third locking part 600 includes a third locking plate 601, on which a first driving part C602 and a second driving part C603 are provided, the first driving part C602 has a slope that matches with the slope of the first driving part B403, the second driving part C603 has a slope that matches with the slope of the second driving part B402, and the second driving part C603 also has a slope that matches with the slope of the second push block 700.

[0045] In order to better drive the first push block to move, in one embodiment, the driving part is installed on the installation shaft by means of a thread; one end of the installation shaft is provided with a threaded part, and the other end is a limiting part for placing a locking strip or the push part to fall off, and the driving part cooperates with the threaded part and has an internal thread. This setting can realize the driving of the push part, the method is simple to operate, and can play a self-locking role to prevent the push part from retreating after locking.

[0046] In order to facilitate the staff to rotate the drive part, such as Figure 1 As shown, in one embodiment, the driving portion 200 is provided with a rotating portion, which is a notch (or groove) provided at the end.

[0047] In order to facilitate the installation of the entire three-way locking strip, in one embodiment, a connecting block 800 is also installed on the installation shaft 100, and the connecting block is located on the non-locking surface, which refers to the side of the installation shaft where the locking strip is not installed. The second drive part A503 is located between the first drive part C602 and the second drive part A503; further, in order to improve the positioning of the connecting block, the connecting block has two raised mounting parts, which are cylindrical and have threaded holes; positioning and anti-rotation can be achieved through the two cylindrical mounting parts, and the threaded holes are provided to facilitate the staff to install the locking strip through bolts.

[0048] like Figure 1When the three-way locking strip shown is in use, the staff rotates the driving part, the driving part pushes the pushing part to move, and the pushing part then pushes the second locking part 500 to extend. When the second locking part 500 moves, it pushes the first locking part 400 to extend through the inclined surface; and the third locking part 600 is pushed by the inclined surface of the first locking part 400 and guided by the inclined surface of the second push block, and extends outward to achieve locking.

[0049] For example, locking is achieved by the following operations:

[0050] The driving part is rotated and pushed forward under the action of the threaded part, pushing the first push block to move, and the inclined surface of the first push block cooperates with the inclined surface of the first driving part A502 to push the second locking part 500 to extend; while the second locking part moves, the first driving part A502 pushes the first driving part B403 through the inclined surface, and the second driving part A503 pushes the second driving part B402 through the inclined surface, so as to extend the first locking part; while the first locking part is extended, the first driving part B403 pushes the first driving part C602 through the inclined surface, and the inclined surface of the second driving part B402 and the inclined surface of the second push block act together on the second driving part C603, and the third locking part is extended. After the three locking parts are extended to the specified end, the rotating driving part is stopped to complete the locking;

[0051] For example, unlocking is achieved through the following operations:

[0052] The rotating part is rotated in the opposite direction to make the first push block retreat, the thrust between the inclined surfaces disappears, and the locking parts retreat under the action of gravity or the squeezing force given by the module to complete the unlocking.
