[0019] To make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a light anti-tipping transfer device, the structure of which is as Figure 1 - Figure 6 shown, including a moving base 1, a lifting frame 2 and a support frame 3.

[0021] The lifting frame 2 includes a first lifting seat 21, two first lifting rods 22, two second lifting rods 23, a second lifting seat 24 and a driving assembly 25. The first lifting seat 21 is connected to the moving base 1. One end of each of the two first lifting rods 22 is hinged to the first lifting seat 21. One end of each of the two second lifting rods 23 is respectively hinged to one end of the two first lifting rods 22 away from the first lifting seat 21. One end of the two second lifting rods 23 away from the first lifting rods 22 is hinged to the second lifting seat 24. The driving assembly 25 is used to drive the two first lifting rods 22 and the two second lifting rods 23 to approach or separate from each other.

[0022] The support frame 3 is connected to the second lifting seat 24, and the support frame 3 is used to support the seat.

[0023] During use, the moving base 1 provides a moving foundation for the entire device. When the driving assembly 25 drives the two first lifting rods 22 to rotate away from each other, the second lifting seat 24 will descend as the first lifting rods 22 and the second lifting rods 23 unfold. On the contrary, when the driving assembly 25 drives the two first lifting rods 22 to rotate towards each other, the second lifting seat 24 will rise. The support frame 3 is connected to the movable end of the lifting frame 2. When the support frame 3 is adjusted to match the height of the top of the aircraft cabin mounting seat through the lifting frame 2, at this time, the seat is stably supported by the support frame 3. During the installation of the seat, the staff does not need to keep lifting the seat all the time and only needs to perform some auxiliary installation operations.

[0024] In the present invention, through the height adjustment function of the lifting frame 2, the support frame 3 can be adapted to mounting seats of various different heights, greatly improving the versatility of seat installation and being able to solve the problem regardless of the cabin installation environment of any model of aircraft.

[0025] To realize the lifting of the support frame 3, please refer to Figure 3 , in a preferred embodiment, the driving assembly 25 includes a lead screw 251 and two rotating rods 252. The ends of the first lifting rods 22 and the second lifting rods 23 are rotatably connected through the rotating rods 252. The lead screw 251 is threadedly connected to the two rotating rods 252.

[0026] In use, the lead screw 251 is threadedly connected to the two rotating rods 252. When the operator rotates the lead screw 251, due to the threaded fit between the lead screw 251 and the rotating rods 252, the rotation of the lead screw 251 will be converted into the movement of the rotating rods 252 along the axial direction of the lead screw 251. The ends of the first lifting rod 22 and the second lifting rod 23 are rotatably connected by the rotating rods 252. When the lead screw 251 rotates to bring the two rotating rods 252 closer, the rotating rods 252 will drive the first lifting rod 22 and the second lifting rod 23 connected thereto to move. Since one end of the first lifting rod 22 is hinged to the first lifting seat 21, one end of the second lifting rod 23 is hinged to the end of the first lifting rod 22 away from the first lifting seat 21, and the other end is hinged to the second lifting seat 24, when the two rotating rods 252 approach, the angle between the first lifting rod 22 and the second lifting rod 23 will become larger, resulting in the rise of the second lifting seat 24, and the support frame 3 connected to the second lifting seat 24 will also rise accordingly. Conversely, when the lead screw 251 rotates to move the two rotating rods 252 away from each other, the rotating rods 252 drive the first lifting rod 22 and the second lifting rod 23 to move, reducing the angle between the first lifting rod 22 and the second lifting rod 23, and further causing the second lifting seat 24 to descend, and the support frame 3 also follows to descend.

[0027] For the convenience of rotating the lead screw 251, please refer to Figure 3 , in a preferred embodiment, the driving assembly 25 further includes a hexagonal bolt 253 and a wrench 254. The hexagonal bolt 253 is fixedly connected to the end of the lead screw 251, and the wrench 254 is sleeved on the nut of the hexagonal bolt 253.

[0028] In use, when the wrench 254 is sleeved on the nut of the hexagonal bolt 253, the operator applies a force to the wrench 254 to make the wrench 254 rotate around the central axis of the hexagonal bolt 253. Since the wrench 254 is in close fit with the nut of the hexagonal bolt 253, the force applied by the operator on the wrench 254 will be converted into a torque on the hexagonal bolt 253. The hexagonal bolt 253 is fixedly connected to the end of the lead screw 251. Therefore, after receiving the torque transmitted by the wrench 254, the hexagonal bolt 253 will transmit this torque to the lead screw 251, driving the lead screw 251 to rotate together. Using the simple mechanical structure composed of the wrench 254 and the hexagonal bolt 253, the rotation of the lead screw 251 can be controlled conveniently and efficiently, and then the height of the lifting frame 2 can be accurately adjusted.

[0029] To further reduce the operation difficulty, please refer to Figure 3 , in a preferred embodiment, the wrench 254 is a ratchet wrench 254.

[0030] In use, the design of the ratchet wrench 254 makes it unnecessary to completely disengage from the bolt nut and then re - sleeve it every time after rotation during operation, which is more labor - saving.

[0031] To improve the stability of the seat during transportation, please refer to Figure 1 In a preferred embodiment, the support frame 3 includes a frame body 31 and two receiving grooves 32. The frame body 31 is connected to the second lifting seat 24. The two receiving grooves 32 are respectively arranged at both ends of the frame body 31, and are respectively used to receive the front chair tube and the rear chair tube of the seat.

[0032] During use, when installing the seat, place the seat on the support frame 3, and insert the front chair tube and the rear chair tube of the seat into the two receiving grooves 32 respectively. The shape and size of the receiving groove 32 are adapted to the chair tube, which can play a good role in limiting and fixing the chair tube, preventing the seat from moving or shaking back and forth or left and right on the support frame 3.

[0033] To further improve the stability of the seat during transportation, please refer to Figure 2 In a preferred embodiment, the transportation device further includes a connecting seat 5, two limiting seats 51 and two limiting telescopic rods 52. The connecting seat 5 is connected to the frame body 31. The two limiting seats 51 are respectively connected to both sides of the connecting seat 5. The fixed ends of the two limiting telescopic rods 52 are respectively connected to the two limiting seats 51. When the two receiving grooves 32 support the front chair tube and the rear chair tube of the seat, the limiting telescopic rods 52 are in an extended state, and the limiting telescopic rods 52 support on the luggage gear lever.

[0034] During use, when transporting the seat, the center of gravity of the seat is at the rear chair tube. When the seat is lifted off the ground, the seat is likely to flip backward along the axis of the rear chair tube. Therefore, before the seat is lifted off the ground, the limiting telescopic rod 52 is in an extended state, its fixed end is connected to the limiting seat 51, and the movable end supports on the luggage gear lever. Taking the axis of the rear chair tube as the rotation axis, the moments of the center of gravity of the seat to the rotation axis and the luggage gear lever to the rotation axis form a balance, restricting the seat from flipping backward.

[0035] To realize the telescoping of the limiting telescopic rod 52, please refer to Figure 2 In a preferred embodiment, the limiting telescopic rod 52 includes a sleeve 521 and a sliding rod 522. The sleeve 521 is connected to the limiting seat 51, and the sliding rod 522 is slidably connected to the sleeve 521 along the axial direction of the sleeve 521.

[0036] During use, after the front chair tube and the rear chair tube of the seat are supported by the receiving grooves 32. At this time, when the limiting telescopic rod 52 is supported on the luggage gear lever, the sliding rod 522 will extend out of the sleeve 521. According to the distance between the luggage gear lever and the limiting seat 51, under the external force, the sliding rod 522 slides outward along the axial direction of the sleeve 521 until the end of the sliding rod 522 can contact the luggage gear lever and provide a supporting force.

[0037] To improve the stability of the sliding rod 522, please refer to Figure 4 In a preferred embodiment, the limiting telescopic rod 52 further includes a locking block 523. The locking block 523 is connected to the sliding rod 522. A sliding groove 524 and a locking groove 525 for accommodating the locking block 523 are provided on the sleeve 521. The sliding groove 524 extends along the axial direction of the sleeve 521, and the locking groove 525 extends along the radial direction of the sleeve 521.

[0038] During use, when the length of the limiting telescopic rod 52 needs to be adjusted, the sliding rod 522 drives the locking block 523 to slide within the sleeve 521. Since the locking block 523 is located within the sliding groove 524, it can only move along the direction of the sliding groove 524, that is, the axial direction of the sleeve 521. When the sliding rod 522 extends or retracts to a suitable position, the locking block 523 will correspond to the locking groove 525. Since the locking groove 525 extends along the radial direction of the sleeve 521, at this time, the sliding rod 522 can be rotated to make the locking block 523 enter the locking groove 525 from the sliding groove 524. After the locking block 523 enters the locking groove 525, its movement is restricted in the radial direction, thereby preventing the sliding rod 522 from continuing to slide in the axial direction, achieving the locking of the position of the sliding rod 522, enabling the limiting telescopic rod 52 to stably maintain the current length, and providing reliable limiting and support for the seat.

[0039] To simplify the structure of the moving base 1, please refer to Figure 5 In a preferred embodiment, the moving base 1 includes a longitudinal frame 11 and a transverse frame 12. The longitudinal frame 11 extends along the length direction of the seat, the transverse frame 12 extends along the width direction of the seat. The end of the longitudinal frame 11 is connected to the middle of the transverse frame 12. Universal wheels 13 are installed at both ends of the end of the longitudinal frame 11 and the transverse frame 12. The first lifting seat 21 is connected to the longitudinal frame 11.

[0040] During use, the longitudinal frame 11, the transverse frame 12 and the universal wheels 13 together constitute a stable structure of the moving base 1. When the transfer equipment is working, the longitudinal frame 11 and the transverse frame 12 provide a stable support platform, bearing the weight and force from above, and the universal wheels 13 enable the equipment to have flexible mobility.

[0041] To adapt to seats of different sizes, please refer to Figure 6 In a preferred embodiment, the transverse frame 12 includes a fixed frame 121, two moving frames 122 and two locking bolts 123. The fixed frame 121 is connected to the longitudinal frame 11. The two moving frames 122 are respectively slidably connected to both ends of the fixed frame 121. The two universal wheels 13 are respectively installed at the ends of the moving frames 122. A plurality of screw holes 124 are provided on the fixed frame 121 at intervals along the sliding direction of the moving frames 122. A groove 125 is provided on the moving frame 122. The bolt is threadedly connected to any one of the screw holes 124, and the bolt passes through the groove 125.

[0042] During use, when it is necessary to adjust the width of the cross frame 12 to fit seats of different widths, the operator can manually push the movable frame 122 according to the actual width of the seat, so that it moves on the fixed frame 121 along the preset sliding direction. After adjusting the movable frame 122 to the appropriate position, screw the locking bolt 123 into the corresponding screw hole 124. As the bolt is tightened, the head of the bolt will closely contact the bottom of the groove 125 on the movable frame 122, generating frictional force and extrusion force, thereby firmly fixing the movable frame 122 on the fixed frame 121. Ensure that the width of the cross frame 12 remains stable and provides reliable support for the seat. When it is necessary to adjust the width of the cross frame 12 again, just loosen the locking bolt 123 to loosen the threaded connection between it and the screw hole 124 and release the locking of the movable frame 122. At this time, the movable frame 122 can slide freely on the fixed frame 121 for the next width adjustment operation.

[0043] To better understand the present invention, the following is combined with Figure 1 - Figure 6 The working principle of a technical solution of the present invention, a lightweight anti-tipping transfer device, is described in detail: The mobile base 1 provides a moving foundation for the entire device. When the driving assembly 25 drives the two first lifting rods 22 to rotate away from each other, the second lifting seat 24 will descend as the first lifting rod 22 and the second lifting rod 23 unfold. On the contrary, when the driving assembly 25 drives the two first lifting rods 22 to rotate towards each other, the second lifting seat 24 will rise. The support frame 3 is connected to the movable end of the lifting frame 2. When the support frame 3 is adjusted to match the height of the top of the aircraft cabin mounting seat through the lifting frame 2, at this time, the seat is stably supported by the support frame 3. During the installation of the seat, the staff does not need to keep lifting the seat all the time and only needs to perform some auxiliary installation operations.

[0044] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention.
