BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 yes Figure 1 Schematic diagram of the other side. DETAILED DESCRIPTION

[0015] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] like Figures 1 to 2 As shown, the present invention provides an aviation seat maintenance vehicle, comprising a vehicle body 1, a reclining assembly 2, a measuring tool 3, and a compression assembly 4; wheels are provided at the bottom of the vehicle body 1, and a bottom plate 11 for fixing the seat is provided at the front of the vehicle body 1;

[0018] The reclining assembly 2 includes a backrest plate 21, a shaft, a connecting rod 22, a ball screw 23, and a handle 24. The ball screw 23 is rotatably connected to the vehicle body 1, and the bottom end of the connecting rod 22 is hinged to the screw nut on the ball screw 23. The backrest plate 21 is arranged behind the base plate 11, and its side near the base plate 11 is hinged to the vehicle body 1. The shaft is fixed to the back side of the backrest plate 21, and the top end of the connecting rod 22 is hinged to the shaft, so that the backrest plate 21 can be adjusted up and down. The handle 24 is connected to the end of the ball screw 23, driving the ball screw 23 to rotate about the axis.

[0019] The measuring tool 3 and the compression assembly 4 are vertically arranged on the vehicle body 1, located on the side of the bottom plate 11; the compression assembly 4 includes a vertically arranged telescopic device and a pressing head 41, and the pressing head 41 is installed on the top of the telescopic device.

[0020] The vehicle body 1 can be moved freely with other components, enhancing maneuverability. However, if the airline seat needs to be repaired, it can be fixed to the base plate 11. If the backrest needs to be folded down, the reclining assembly 2 can be adjusted so that the backrest rests on the backrest plate 21. Specifically, rotating the handle 24 rotates the ball screw 23, which in turn drives the screw nut, which in turn drives the connecting rod 22 to support the backrest plate 21. The reverse operation can also lower the backrest plate 21.

[0021] If necessary, you can also open the seat panel of the airline seat to repair the many internal adjustment devices.

[0022] Specifically, the telescopic device of the compression assembly 4 is preferably composed of an electric cylinder 42 and a rotating arm 43. The rotating arm 43 is rotatably connected to the top of the vertically arranged electric cylinder 42 so that the rotating arm 43 can rotate horizontally; the pressure head 41 is fixedly installed at the end of the rotating arm 43.

[0023] When the seat panel is lifted, a pneumatic spring is located inside the seat to adjust the seat's height. This spring, when raised, can hinder seat maintenance, and manually depressing it requires considerable force. A compression assembly 4 automatically compresses the pneumatic spring. First, rotate the rotating arm 43 to align the pressure head 41 with the top of the pneumatic spring. Then, activate the electric cylinder 42 to depress the pressure head 41. The electric cylinder 42 exerts a significant force, eliminating manual operation.

[0024] Specifically, the bottom of the measuring tool 3 is hinged to the vehicle body 1, allowing it to be folded down. The measuring tool 3 is used to measure whether the armrest or airline seat has reached the required height. During routine maintenance, if the measuring tool 3 is not needed, it can be folded down to avoid interfering with maintenance operations.

[0025] Preferably, the back side of the bottom plate 11 is hinged to the vehicle body 1 so that it can be flipped backward. When the entire airline seat needs to be folded down to inspect and repair the bottom of the airline seat, the bottom plate 11 can be flipped backward. At this time, the entire airline seat is supported on the back plate 21.

[0026] The aircraft seat repair vehicle of this utility model is highly maneuverable and can be moved freely. Its reclining assembly 2 allows the aircraft seat to recline against the backrest 21, facilitating various repair operations. The compression assembly 4 automatically compresses the pneumatic spring, saving effort and providing convenience. It also features a measuring tool 3 that can be lowered and raised to check if the aircraft seat meets standards. With its simple structure, labor-saving and convenient operation, it effectively improves repair efficiency.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
