DETAILED DESCRIPTION

[0037] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0038] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the "upper" and "lower" of the corresponding parts in the use state relative to the direction of gravity, and "inside" and "outside" refer to the "inside" and "outside" relative to the corresponding parts' own contours. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements.

[0039] A pod is a streamlined short section that is installed with airborne equipment or weapons and is hung under the fuselage or wing. It can be fixed (such as an engine pod) or detachable (such as a weapon pod). Adding a pod can give the aircraft functions that it does not have on its own.

[0040] refer to Figure 1 to Figure 2 The pod 1 includes a pod body 101 , a tail end of the pod body 101 having an ammunition box entrance and exit, and a hatch 102 is provided at the ammunition box entrance and exit.

[0041] According to the embodiments of the present application, reference Figures 3 to 6 , providing an ammunition box connection structure for connecting the ammunition box 2 to the pod 1, the ammunition box connection structure comprising: a first fixing plate 201, a first positioning plate 103, a second fixing plate 203, a second positioning plate 105, and a locking assembly.

[0042] refer to Figure 3 , wherein the first fixing plate 201 is arranged on the ammunition box 2, and two first positioning shafts 202 are arranged on the front side of the first fixing plate 201, and the central axis of the first positioning shaft 202 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101. Figure 4 The first positioning plate 103 is disposed in the cabin 101 . The first positioning plate 103 is provided with two first positioning holes 104 into which two first positioning shafts 202 can be inserted. The central axis of the first positioning hole 104 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 .

[0043] refer to Figure 3 and Figure 6 The second fixing plate 203 is disposed on the ammunition box 2, and a second positioning shaft 204 is disposed on the front side of the second fixing plate 203, and the central axis of the second positioning shaft 204 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101; Figure 4 Correspondingly, the second positioning plate 105 is arranged in the cabin 101 , and a second positioning hole 106 into which the second positioning shaft 204 can be inserted is provided on the second positioning plate 105 , and the central axis of the second positioning hole 106 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 .

[0044] In this way, when the two first positioning shafts 202 enter the two first positioning holes 104, the first fixing plate 201 contacts the first positioning plate 103, and the second positioning shaft 204 enters the second positioning hole 106, the second fixing plate 203 contacts the second positioning plate 105, that is, the three points in space determine a plane, which means that the relative positions of the ammunition box 2 and the pod 1 are accurately aligned. At this time, refer to Figure 5 The locking assembly is used to lock or unlock the ammunition box 2 and the cabin body 101. The locking assembly can lock the position of the ammunition box 2 and the pod 1. The ammunition box connection structure of this embodiment can quickly and accurately position and lock or unlock the ammunition box 2 and the pod 1, thereby improving the installation accuracy of the ammunition box 2 and the reliability of the connection.

[0045] In the examples of this application, reference is made to Figures 3 to 6, the first fixing plate 201 is arranged on the front side of the ammunition box 2 and is perpendicular to the direction of the ammunition box 2 entering and exiting the cabin 101, and the first positioning plate 103 is perpendicular to the direction of the ammunition box 2 entering and exiting the cabin 101; the second fixing plate 203 is arranged on the left side or right side of the ammunition box 2 and is perpendicular to the direction of the ammunition box 2 entering and exiting the cabin 101, and the second positioning plate 105 is perpendicular to the direction of the ammunition box 2 entering and exiting the cabin 101. In this case, the first fixing plate 201 and the first positioning plate 103 are parallel to each other, and the second fixing plate 203 and the second positioning plate 105 are parallel to each other and are perpendicular to the direction of the ammunition box 2 entering and exiting the cabin 101. In this way, the first fixing plate 201 and the first positioning plate 103 collide head-on, and the second fixing plate 203 and the second positioning plate 105 also collide head-on, and no force in other directions will be generated, so the structure is more reliable.

[0046] In the examples of this application, reference is made to Figure 7 and Figure 8 The locking assembly includes: a connecting frame 3, a U-shaped handle 4, a hinge shaft 5, and a locking shaft 6.

[0047] refer to Figure 5 , wherein the connection frame 3 is fixedly connected to the rear of the cabin 101, refer to Fig. 9 , two first hinge holes 301 are horizontally arranged on the connection frame 3, and the central axes of the two first hinge holes 301 are collinear. Figure 7 , Figure 8 and Fig.10 The U-shaped handle 4 includes two parallel connecting arms 401 and a pull rod 402 connecting the two connecting arms 401. The free end of each connecting arm 401 has a square hinge hole 4011, and the other end has a second hinge hole 4012. Fig.11 The hinge shaft 5 has a square shaft section 501 corresponding to the square hinge hole 4011, and the head of the hinge shaft 5 has a C-shaped cylinder 502 extending axially, the opening 5021 of the C-shaped cylinder 502 is smaller than the inner diameter of the C-shaped cylinder 502, and the second hinge hole 4012 is used to connect the end of the pull rod 402.

[0048] refer to Figure 7 and Figure 8 The two connecting arms 401 of the U-shaped handle 4 are respectively hinged to the two first hinge holes 301 through the hinge shaft 5. Fig.11 The square shaft section 501 of the hinge shaft 5 corresponds to the square hinge hole 4011 of the connecting arm 401. In this way, when the U-shaped handle 4 is rotated, the two connecting arms 401 can drive the hinge shaft 5 to rotate, thereby driving the C-shaped tube 502 connected to the head of the hinge shaft 5 to rotate. That is, rotating the U-shaped handle 4 in this embodiment can drive the C-shaped tube 502 of the hinge shaft 5 to rotate.

[0049] refer to Figure 4A locking shaft 6 is horizontally arranged at the rear of the cabin 101. Fig.12 and Fig.13 The locking shaft 6 has an axial flattened portion 601, the size of the axial flattened portion 601 is less than or equal to the size of the opening 5021 of the C-shaped cylinder 502, and the plane portion of the axial flattened portion 601 is parallel to the direction in which the ammunition box 2 enters and exits the cabin body 101; wherein, when the ammunition box 2 moves toward the cabin body 101 and the U-shaped handle 4 is rotated until the opening 5021 of the C-shaped cylinder 502 is parallel to the plane portion of the axial flattened portion 601, the locking shaft 6 can enter the C-shaped cylinder 502; when the locking shaft 6 is located in the C-shaped cylinder 502, the U-shaped handle 4 is rotated so that the opening 5021 of the C-shaped cylinder 502 is not parallel to the plane portion of the axial flattened portion 601, and the C-shaped cylinder 502 can lock the locking shaft 6. In a specific embodiment, when the U-shaped handle 4 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 , the opening 5021 of the C-shaped tube 502 is also parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 , and the opening 5021 of the C-shaped tube 502 faces the ammunition box 2 .

[0050] refer to Fig.12 In this case, when the U-shaped handle 4 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 (when the aircraft is stopped, the U-shaped handle 4 is in a horizontal direction), the staff can directly push the ammunition box 2 into the cabin 101, and the locking shaft 6 can enter the C-shaped cylinder 502 through the opening 5021 of the C-shaped cylinder 502. Then, refer to Fig.13 , the staff rotates the U-shaped handle 4 to be perpendicular to the direction in which the ammunition box 2 enters and exits the cabin 101 (when the aircraft is stopped, the U-shaped handle 4 is in a vertical state, that is, in the direction of gravity, and is therefore more stable), and the ammunition box 2 and the cabin 101 can be locked. When the staff needs to remove the ammunition box 2 to reload ammunition, the U-shaped handle 4 is rotated to be parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 and the ammunition box 2 is pulled backward, and the locking shaft 6 can be disengaged from the C-shaped cylinder 502 of the hinge shaft 5, and the ammunition box 2 and the cabin 101 are unlocked.

[0051] In the examples of this application, reference is made to Fig.12 and Fig.13 There are two axial flattening positions 601, the two axial flattening positions 601 are parallel to each other, and the opening 5021 of the C-shaped cylinder 502 is larger than the distance between the plane parts of the two axial flattening positions 601. In practice, the distance between the two flattening positions is slightly smaller than the size of the opening 5021 of the C-shaped cylinder 502.

[0052] In the examples of this application, reference is made to Figures 7 to 10 The ammunition box connection structure may also include a safety pin 7, refer to Fig.10 , and a first pin hole 4013 is provided on the connecting arm 401. Fig. 9A second pin hole 302 is provided on the connecting frame 3. When the connecting arm 401 rotates to be parallel to the connecting frame 3, the first pin hole 4013 and the second pin hole 302 are collinear, and the safety pin 7 is used to be inserted into the first pin hole 4013 and the second pin hole 302 at the same time.

[0053] In this case, when the U-shaped handle 4 rotates to a position perpendicular to the direction in which the ammunition box 2 enters and exits the cabin 101, the safety pin 7 is simultaneously inserted into the first pin hole 4013 and the second pin hole 302, which can further reliably lock the U-shaped handle 4 and the connecting frame 3, preventing the ammunition box 2 and the cabin 101 from being unlocked when the U-shaped handle 4 automatically rotates to a position parallel to the direction in which the ammunition box 2 enters and exits the cabin 101 during the flipping of the aircraft.

[0054] The safety pin 7 can be an open 5021 pin purchased on the market, or a ball lock pin.

[0055] refer to Fig.14 The ball lock pin is a self-locking quick-release pin. In the natural state, the ball 701 is in a pop-up shape. When it is necessary to remove it, just press the pressing cylinder 702, and the ball 701 will automatically retract. When it is necessary to unlock the ammunition box 2 and the cabin 102, just press the pressing cylinder 702, and the ball 701 will automatically retract and the ball lock pin can be taken out from the first pin hole 4013 and the second pin hole 302. The ball lock pin can quickly unlock the ammunition box 2 and the cabin 101, saving time.

[0056] In the examples of this application, reference is made to Fig.10 The end of the connecting arm 401 with the square hinge hole 4011 has a positioning plane portion 4014 and a rotating semicircular portion 4015; the positioning plane portion 4014 is perpendicular to the connecting line between the square hinge hole 4011 and the second hinge hole 4012, and the rotating semicircular portion 4015 is located on the side of the connecting arm 401 close to the connecting frame 3.

[0057] refer to Figure 8 When the connecting arm 401 rotates to be perpendicular to the connecting frame 3, the positioning plane portion 4014 contacts the plane of the connecting frame 3. In this case, when the connecting arm 401 rotates to be perpendicular to the connecting frame 3, the positioning plane portion 4014 contacts the plane of the connecting frame 3. At this time, the U-shaped handle 4 is in a stable state of being pulled up, and the U-shaped handle 4 can be kept at a certain distance from the connecting frame 3, which is convenient for the staff to quickly grasp the U-shaped handle 4. The positioning plane portion 4014 and the rotating semicircular portion 4015 can have a rounded transition.

[0058] In the examples of this application, reference is made to Fig.15The ammunition box connection structure may also include a guide structure, which includes: two guide rails 107, which are arranged in parallel in the cabin 101, and the extension direction of each guide rail 107 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101; and roller fixing plates 205 fixedly connected to both sides of the ammunition box 2, each roller fixing plate 205 is parallel to the direction in which the ammunition box 2 enters and exits the cabin 101, and each roller fixing plate 205 is provided with a plurality of rollers 206. In this way, the ammunition box 2 can be guided and the friction between the ammunition box 2 and the inner wall of the cabin 101 can be reduced, so that the ammunition box 2 can enter and exit the cabin 101 more quickly.

[0059] Reference Figures 1 to 15 The following is a description of the implementation principle of the ammunition box connection structure of the present application in conjunction with the installation process of the ammunition box 2.
