[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-6 A mechanical locking device for the cabin door of a low-altitude sightseeing aircraft includes a lock body 1 and a mounting base 6. The lock body 1 is mounted on the aircraft cabin door, while the mounting base 6 is mounted on the aircraft body and is parallel to the lock body 1. The mounting base 6 has two sets of mounting holes 4 inside. The lock body 1 has a groove 10 inside. A slider 8 is slidably connected inside the groove 10. Two sets of locking rods 5 are welded to one side of the slider 8. The locking rods 5 are parallel to the mounting holes 4. An adjustment component 2 is provided on the inner wall of the groove 10. A drive component 3 is provided on the outer side of the lock body 1, and one side of the drive component 3 is fixedly connected to one side of the adjustment component 2.

[0026] Specifically, in order to make the slider 8 move back quickly, a first spring 9 is fixedly connected to one side of the slider 8. The end of the first spring 9 away from the slider 8 is fixedly connected to the inner wall of the groove 10. Thus, when the slider 8 is pushed, the first spring 9 will be squeezed by the slider 8, and when the slider 8 is no longer pushed, the first spring 9 will drive the locking roller 5 to move back by bouncing the slider 8 back.

[0027] First, refer to Figures 2 to 4In this embodiment, the adjusting component 2 includes a horizontal plate 201, which is welded to the inner wall of the groove 10. A movable plate 208 is slidably connected inside the horizontal plate 201, and a push plate 205 is slidably connected inside the movable plate 208. The side of the push plate 205 away from the movable plate 208 contacts the side of the slider 8. A central shaft 207 is welded to both sides of the push plate 205. A pulley 206 is rotatably connected to the outer side of the central shaft 207. Two sets of protrusions 202 are welded to the side of the horizontal plate 201 near the slider 8. The protrusions 202 are semi-elliptical. The outer side of the pulley 206 contacts the side of the protrusion 202. One side of the horizontal plate 201 is fixedly connected to one side of the driving component 3.

[0028] Specifically, in order to maintain the balance of the slider 8, two sets of limiting rods 204 are slidably connected inside the horizontal plate 201, and one end of the limiting rod 204 is welded to the slider 8. Thus, on the one hand, the limiting rod 204 maintains the balance of the slider 8 during movement, preventing the slider 8 from becoming unbalanced and wobbling during movement, and ensuring the normal displacement of the slider 8. On the other hand, the limiting rod 204 restricts the direction of the slider 8, preventing the device from failing due to misalignment of the slider 8, and ensuring the normal use of the device.

[0029] Meanwhile, in order to prevent the slider 8 from being damaged due to excessive back movement, a buffer pad 203 is fixedly connected to the outside of the limiting rod 204. The buffer pad 203 is a rubber buffer pad, and the buffer pad 203 is located on the side of the horizontal plate 201 close to the slider 8. Therefore, when the buffer pad 203 contacts the horizontal plate 201, the slider 8 will not be able to move back, thus avoiding the situation where the slider 8 is damaged due to excessive back movement.

[0030] When the movable plate 208 moves down, it will push the push plate 205 down. The downward movement of the push plate 205 will drive the pulley 206 to move by displacing the central shaft 207. When the pulley 206 moves down, it will be pushed by the protrusion 202 and move laterally. The lateral movement of the pulley 206 will drive the push plate 205 to move laterally by driving the central shaft 207, thereby pushing the slider 8 to move laterally. The lateral movement of the slider 8 will drive the locking rod 5 to move, thereby locking the locking rod 5 into the mounting hole 4. At this time, the locking rod 5 will connect the mounting base 6 and the lock body 1 by locking the mounting base 6. The connection between the mounting base 6 and the lock body 1 will lock the door to the aircraft body, so that the door is closed stably.

[0031] Then, refer to Figure 1 , Figure 2 and Figure 5In this embodiment, the drive assembly 3 includes a bearing 301, which is disposed on one side of the lock body 1. A threaded tube 304 is disposed in the middle of the bearing 301, and a sleeve 303 is screwed onto the outer side of the threaded tube 304. The rotation of the threaded tube 304 will cause the sleeve 303 to move linearly. A connecting frame 302 is disposed on the outer side of the sleeve 303. The side of the connecting frame 302 away from the sleeve 303 extends into the lock body 1 and is fixedly disposed with the movable plate 208. A protective cover 7 is disposed on the outer side of the lock body 1, and the protective cover 7 is located outside the bearing 301 and the threaded tube 304. Thus, the threaded tube 304 and the bearing 301 can be protected by the protective cover 7. A handle 306 is provided at the end of the threaded tube 304 away from the bearing 301. Multiple sets of fixing holes 305 are opened inside the handle 306, so the threaded tube 304 can be rotated conveniently through the handle 306. When the handle 306 is rotated to make the threaded tube 304 rotate, the rotation of the threaded tube 304 will cause the sleeve 303 to move linearly. The movement of the sleeve 303 will cause the connecting frame 302 to move. The movement of the connecting frame 302 will cause the movable plate 208 to move longitudinally.

[0032] Finally, refer to the figure. Figure 1 , Figure 2 and Figure 6 In this embodiment, a support plate 11 is welded to the outside of the protective cover 7. A locking rod 14 is slidably connected inside the support plate 11. A movable disc 13 is welded to the outside of the locking rod 14. A second spring 12 is fixedly connected between the movable disc 13 and the support plate 11. One end of the locking rod 14 is engaged in the fixing hole 305. When the locking rod 14 is engaged in the fixing hole 305, the handle 306 cannot be rotated. After moving the locking rod 14 to disengage it from the fixing hole 305, the handle 306 will no longer be fixed, and the operator can rotate the handle 306.

[0033] The mechanical locking device for the cabin door of this low-altitude sightseeing aircraft works by engaging the locking rod 5 and the mounting hole 4. After the cabin door is closed, the locking rod 5 moves and engages with the mounting hole 4 to secure the mounting base 6. At this point, the lock body 1 will be stably connected to the mounting base 6. The connection between the lock body 1 and the mounting base 6 will stably lock the cabin door to the aircraft body, thus closing the cabin door. This avoids the situation where the structural design is too complex, making it difficult for operators to open and close the cabin door.

[0034] Working principle:

[0035] When using the mechanical locking device for the cabin door of the low-altitude sightseeing aircraft, first place the device in the desired position, then lock the door. Specifically, move the locking lever 14 to disengage it from the fixing hole 305, then turn the handle 306 to rotate the threaded tube 304. The rotation of the threaded tube 304 will cause the sleeve 303 to move linearly. The movement of the sleeve 303 will cause the connecting frame 302 to move. The movement of the connecting frame 302 will cause the movable plate 208 to move longitudinally. When the movable plate 208 moves downward, it will push the push plate 205 downward. The downward movement of the push plate 205 will cause the pulley 206 to move by moving the central shaft 207. When the pulley 206 moves downward, it will be stopped by the protrusion 20. The pulley 206 moves laterally, and the lateral movement of the pulley 206 will drive the push plate 205 to move laterally by driving the central shaft 207. This push plate 205 will push the slider 8 to move laterally, and the lateral movement of the slider 8 will drive the locking rod 5 to move, so that the locking rod 5 will be locked into the mounting hole 4. Then, the rotation of the handle 306 will make one of the multiple sets of fixing holes 305 parallel to the locking rod 14. After the locking rod 14 is released, the second spring 12 will drive the locking rod 14 to move upward and lock into the fixing hole 305 by springing the movable plate 13. At this time, the handle 306 will not be able to rotate. At this time, the locking rod 5 will connect the mounting seat 6 and the lock body 1 by locking the mounting seat 6. The connection between the mounting seat 6 and the lock body 1 will lock the cabin door to the aircraft body, so that the cabin door is closed stably.

[0036] When the cabin door needs to be opened, the reverse handle 306 reverses the threaded tube 304, causing the movable plate 208 to move back. The movement of the movable plate 208 will cause the protrusion 202 to stop pushing the pulley 206. At this time, the first spring 9 will drive the locking rod 5 to move back by springing the slider 8, thereby causing the locking rod 5 to disengage from the mounting seat 6. At this time, the cabin door is no longer locked to the aircraft body, and then the cabin door can be opened.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
