[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, a lifting and locking device for an aircraft cabin door locking handle shaft includes a cabin door body 1. A connecting frame 10 is provided on the inner side of the cabin door body 1. Multiple sets of fixing ribs 11 are provided on the inner side of the connecting frame 10. A fixing frame 12 is provided in the middle of the cabin door body 1. The fixing frame 12 is fixedly connected to the fixing ribs 11. A lifting drive mechanism 2 is provided on the fixing frame 12. Locking side frame one 13 and locking side frame two 14 are provided on both sides of the cabin door body 1. Elastic locking components 3 are provided on the locking side frame one 13 and locking side frame two 14. The lifting drive mechanism 2 is connected to the elastic locking components 3. The lifting drive mechanism 2 drives the elastic locking components 3 to pass through the locking side frame two 14 and engage with the fuselage for locking.

[0031] like Figure 3 , Figure 4 As shown, the lifting drive mechanism 2 includes a fixedly installed plug rod 23. Guide slide rods 24 are provided at both ends of the plug rod 23. A push sleeve 25 is sleeved on the guide slide rod 24. The push sleeve 25 is connected to a drive component. Under the drive of the drive component, the push sleeve 25 moves to both sides along the guide slide rod 24, causing the elastic locking component 3 to pass through the locking side frame 14 and be inserted and locked between it and the machine body.

[0032] Specifically, a lifting drive mechanism 2 is installed on the inner side of the hatch body 1. Combined with the drive assembly, it drives the push sleeve 25 to move along the guide slide 24 to both ends, thereby causing the elastic locking components 3 installed on the locking side frame 13 and locking side frame 24 to extend and engage with the fuselage to complete the locking action. When the drive assembly reverses its direction, the push sleeve 25 releases the thrust on the elastic locking component 3, disengaging the elastic locking component 3 from the fuselage and completing the unlocking action. By controlling the push sleeve 25, rapid locking or unlocking operations between the elastic locking component 3 and the fuselage are achieved, simplifying the unlocking and locking control steps.

[0033] Furthermore, such as Figures 3-5 As shown, the lifting drive mechanism 2 also includes a connecting frame 20, which is fixedly installed with the fixed frame 12. A fixed plate 21 is provided on the connecting frame 20, and a support frame 22 is arranged parallel to the fixed plate 21. The plug-in rod 23 is fixedly installed with the support frame 22. The drive assembly includes an adjusting frame 27, which has a guide groove 28 facing the plug-in rod 23. A mating slider 29 is installed in the guide groove 28. A linkage rod 26 is rotatably installed between the mating slider 29 and the push sleeve 25. The mating slider 29 is connected to the drive unit.

[0034] Furthermore, such as Figure 4 , Figure 5 As shown, the drive unit includes a rotary shaft 211 mounted on an adjustment frame 27. A swing frame 212 is rotatably mounted on the rotary shaft 211. Two sets of swing frames 212 are arranged in parallel. A lifting shaft 218 is provided between the two sets of swing frames 212. Lifting handles 217 are provided at both ends of the lifting shaft 218. A second sliding block 214 is mounted on the swing frame 212. A connecting rod 210 is provided between the first sliding block 214 and the connecting rod 210. A second linkage rod 213 is rotatably mounted between the second sliding block 214 and the swing frame 212. A support spring 215 is provided between the second sliding block 214 and the swing frame 212.

[0035] Specifically, guide grooves 28 are symmetrically arranged on the adjusting frame 27. The sliding block 29 is movably installed on the guide groove 28. When the push sleeve 25 on the guide rod 24 is controlled to slide to both ends to control the elastic locking component 3, the lifting handles 217 at both ends of the lifting shaft 218 are manually controlled to rotate upward, so that the swing frame 212 swings upward. The linkage rod 213 on the swing frame 212 pushes the connecting rod 210 and the sliding block 29 at both ends of the connecting rod 210 to move upward along the guide groove 28. As a result, the linkage rod 26 swings toward the guide rod, thereby controlling the push sleeve 25 to move toward the end of the guide rod 24, which acts on the elastic locking component 3 to achieve the locking action.

[0036] When unlocking is required, flip the lifting handle 217 downwards. The swing frame 212, in conjunction with the linkage rod 213, pulls the connecting rod 210 downwards, causing the mating slider 29 in the guide groove 28 to move downwards simultaneously. This will cause the linkage rod 26 to swing downwards, pushing the sleeve 25 to move along the guide rod 24 toward the side of the insertion rod 23, releasing the force acting on the pushing sleeve 25, and the elastic locking component 3 unlocks and returns to its initial state.

[0037] Furthermore, such as Figure 5 As shown, a slot 216 is provided between the swing frames 212, and a locking shaft 219 is provided at the top of the adjusting frame 27. The slot 216 and the locking shaft 219 cooperate with each other after the swing frame 212 is flipped.

[0038] Specifically, after the lifting handle 217 and the lifting shaft 218 are flipped upward to lock, the lifting shaft 218 is locked by the cooperation between the slot 216 and the locking shaft 219, thus preventing the lifting shaft 218 from falling down on its own and unlocking.

[0039] Furthermore, such as Figure 6 , Figure 7As shown, the elastic locking assembly 3 includes a locking post 30, a blocking ring 330 on one side of the locking post 30, the locking post 30 passing through the locking side frame 13 and the locking side frame 2 14 in sequence, the blocking ring 330 abutting against the edge of the locking side frame 13, a return spring 33 sleeved on the part of the locking post 30 located between the locking side frame 13 and the locking side frame 2 14, and a docking groove 31 on the other side of the locking post 30, the guide slide rod 24 and the docking groove 31 docking with each other.

[0040] Specifically, locking side frame 13 and locking side frame 14 are arranged parallel to each other. Locking post 30, in conjunction with blocking ring 330 and return spring 33, achieves elastic locking. When the lifting drive mechanism 2 drives the pushing sleeve 25 to open to both sides, the pushing sleeve 25 contacts the end of locking post 30 and pushes locking post 30 outward. Return spring 33 is compressed under the action of blocking ring 330, achieving elastic locking. When the lifting drive mechanism 2 controls the pushing sleeve 25 to return to its initial position, locking post 30 returns to its initial position under the action of return spring 33, and the locking post 30 is released from the machine body.

[0041] Furthermore, such as Figure 6 As shown, a linkage frame 32 is fixedly installed on the locking post 30, and a mating post 34 is fixedly installed at both ends of the linkage frame 32. The mating post 34 passes through the locking side frame 13 and the locking side frame 2 14 in sequence. A secondary spring 35 is sleeved on the part of the mating post 34 located between the locking side frame 13 and the locking side frame 2 14.

[0042] Specifically, to improve the locking reliability between the elastic locking component 3 and the fuselage, a linkage frame 32 is connected to the locking pin 30. Each end of the linkage frame 32 has a mating pin 34. When the locking pin 30 moves outward to lock, it simultaneously drives the linkage frame 32 outward, controlling the movement of the mating pins 34 at the ends to engage with the fuselage. This allows the four corners of the hatch body 1 to also engage and lock with the fuselage. The engagement and locking action is completed synchronously by the lifting drive mechanism 2. The mating pins 34, combined with the auxiliary spring 35, can also quickly disengage and unlock from the fuselage during unlocking.

[0043] Furthermore, such as Figure 1 , Figure 8As shown, a push-pull mechanism 4 is provided on the lower side of the fixed rib 11. The push-pull mechanism 4 includes a hinge joint 40 provided on one set of fixed ribs 11. A push-pull frame 41 is hingedly installed on the hinge joint 40. A lifting handle 42 is provided on the push-pull frame 41. The push-pull frame 41 is horizontally arranged. A limit frame 43 is provided on another set of fixed ribs 11. A limit ball 44 is provided in the limit frame 43. A mating groove 45 is provided on the push-pull frame 41 to cooperate with the limit ball 44. A push-pull handle 46 is provided at the end of the push-pull frame 41.

[0044] Specifically, when the hatch 1 is unlocked and closed, the push-pull mechanism 4 achieves effortless control. Before opening the door, after the unlocking action is completed in conjunction with the lifting drive mechanism 2, the lifting handle 42 drives the hatch body 1 to sink and detach from the fuselage. Then, the push-pull handle 46 pushes the hatch body 1 to rotate outward and open. After the hatch body 1 is fully opened, the push-pull handle 46 engages the push-pull frame 41 with the limit frame 43 again. When closing the hatch body 1, the push-pull handle 46 pulls the push-pull frame 41 out of the limit frame 43. After pulling the hatch body 1 to rotate and approach the fuselage, the lifting handle 42 pulls the hatch body 1 up to fit against the fuselage. Then, the lifting drive mechanism 2 controls the elastic locking component 3 to lock with the fuselage.

[0045] Furthermore, such as Figure 1 , Figure 9 As shown, a hinge assembly 5 is provided on the locking side frame 13 and the locking side frame 14 on one side of the hatch body 1. The hinge assembly 5 includes a fixed side frame 50 connected to the body. Multiple connecting frames 51 are provided on the fixed side frame 50. A mating cylinder 510 is provided on the connecting frame 51. A mating shaft 52 is inserted into the mating cylinder 510. Connecting cranks 53 are installed at both ends of the locking side frame 13 and the locking side frame 14. The connecting cranks 53 are connected to the mating shaft 52. A limit ring 56 is provided on the mating cylinder 510. A lifting locking spring 55 is provided between the limit ring 56 and the mating cylinder 510. A sinking spring 57 is provided between the end of the mating shaft 52 and the mating cylinder 510.

[0046] Specifically, to achieve the action of lifting and then engaging when the hatch body 1 closes, and conversely, sinking and then disengaging when the hatch body 1 closes, a engaging shaft 52 is installed in conjunction with the fixed side frame 50 and the connecting frame 2 51. The edge of the engaging shaft 52 is fixedly connected to the locking side frame 1 13 and the locking side frame 2 14 through the connecting crank 53. When the hatch body 1 opens, it is first controlled by the lifting handle 42 in the push-pull mechanism 4 to press down, so that the engaging shaft 52 connected to the hatch body 1 moves down under the action of the sinking spring 57. Then, the push-pull handle 46 in the push-pull mechanism 4 controls the hatch body 1 to open outward. When the hatch 1 closes, after the push-pull handle 46 moves the hatch body 1 close to the fuselage, it is pulled up by the lifting handle 42 on the push-pull frame 41, so that the hatch 1 is lifted. At this time, the engaging shaft 52 connected to the hatch body 1 is lifted under the cooperation of the limit ring 56 and the lifting locking spring 55 until the hatch body 1 is closed.

[0047] The working principle of this invention embodiment is as follows:

[0048] like Figures 1-9As shown, a lifting drive mechanism 2 is installed on the inner side of the hatch body 1. Combined with the drive assembly, it drives the push sleeve 25 to move along the guide slide rod 24 to both ends, thereby causing the elastic locking components 3 installed on the locking side frame 13 and locking side frame 14 to extend and engage with the fuselage to complete the locking action. When the drive assembly reverses its direction, the push sleeve 25 releases the thrust on the elastic locking component 3, disengaging the elastic locking component 3 from the fuselage and completing the unlocking action. By controlling the push sleeve 25, rapid locking or unlocking operations between the elastic locking component 3 and the fuselage are achieved, simplifying the unlocking and locking control steps. The guide groove 28 is symmetrically arranged by the adjusting frame 27. The sliding block 29 is movably installed in the guide groove 28. When the push sleeve 25 on the guide rod 24 is controlled to slide to both ends to control the elastic locking component 3, the lifting handles 217 at both ends of the lifting shaft 218 are manually controlled to rotate upward, so that the swing frame 212 swings upward. The linkage rod 213 on the swing frame 212 pushes the connecting rod 210 and the sliding block 29 at both ends of the connecting rod 210 to move upward along the guide groove 28. As a result, the linkage rod 26 swings toward the guide rod, thereby controlling the push sleeve 25 to move toward the end of the guide rod 24, which acts on the elastic locking component 3 to achieve the locking action. When unlocking is required, the lifting handle 217 is flipped downwards. The swing frame 212, in conjunction with the second linkage rod 213, pulls the connecting rod 210 downwards, causing the mating slider 29 in the guide groove 28 to move downwards simultaneously. This causes the first linkage rod 26 to swing downwards, and the pushing sleeve 25 moves along the guide slide rod 24 towards the side of the insertion rod 23, releasing the force acting on the pushing sleeve 25. The elastic locking assembly 3 unlocks and returns to its initial state. The locking side frame 13 and the second locking side frame 14 are arranged parallel to each other. The locking post 30, in conjunction with the blocking ring 330 and the return spring 33, achieves elastic locking. When the lifting drive mechanism 2 drives the pushing sleeve 25 to open to both sides, the pushing sleeve 25 contacts the end of the locking post 30 and pushes the locking post 30 outwards. The return spring 33 is compressed under the action of the blocking ring 333, achieving elastic locking. When the lifting drive mechanism 2 controls the pushing sleeve 25 to return to its initial position, the locking post 30 returns to its initial position under the action of the return spring 33, and the locking post 30 is unlocked from the machine body. When the hatch 1 is unlocked and closed, the push-pull mechanism 4 achieves effortless control. Before opening the door, after the unlocking action is completed in conjunction with the lifting drive mechanism 2, the hatch body 1 is lowered and detached from the fuselage by the lifting handle 42. Then, the hatch body 1 is pushed outward and opened by the push-pull handle 46. After the hatch body 1 is fully opened, the push-pull frame 41 is re-engaged with the limit frame 43 by the push-pull handle 46. When closing the hatch body 1, the push-pull frame 41 is pulled out of the limit frame 43 by the push-pull handle 46. After the hatch body 1 is pulled to rotate and approach the fuselage, the hatch body 1 is pulled up and close to the fuselage by the lifting handle 42. Then, the elastic locking component 3 is locked with the fuselage by the lifting drive mechanism 2.
