AI Technical Summary
During the folding and packaging process of the Boeing 777-300 aircraft's large wing slide, the slide packaging box is difficult to maintain a horizontal state, resulting in troublesome packaging operation. The lack of special packaging auxiliary tools can easily lead to packaging failure and economic losses.
A support device is designed including a rectangular support frame and a curved inner liner that matches the curved surface of the slide packaging box. The curved inner liner is fixed to the support frame and a rotatable stop is provided on both sides of it to keep the packaging box in a horizontal state and to stabilize its position.
Through this support device, the slide packaging box can be kept horizontal, which facilitates the folding and packaging of the slide, avoids packaging failure and economic losses, and protects the packaging box through a sponge layer to prevent wear or impact.

Abstract
Description
Technical Field
[0001] The utility model relates to a supporting device which is convenient for packing a large wing slide of a Boeing 777-300 aircraft. Background Art
[0002] The wing emergency slide of Boeing 777-300 aircraft is a time-limited part. For aircraft under 15 years old, the slide must be removed for inspection and testing every 3.5 years, and for aircraft over 15 years old, it must be removed for inspection and testing every year. After the inspection and testing, it is folded and packed into the slide packaging box, which is a triangular prism with a curved surface. However, the slide packaging box needs to be kept in a horizontal state during the folding and packaging process, which makes the packaging operation very troublesome. At present, the lack of special packaging auxiliary tools can easily lead to packaging failure and economic losses. Utility Model Content
[0003] The utility model aims to provide a supporting device for packing a large wing slide of a Boeing 777-300 aircraft, which can keep a slide packaging box in a horizontal state and facilitate the folding and packing of the slide.
[0004] The purpose of the utility model can be achieved through the following technical solutions.
[0005] A support device for facilitating the packaging of a large-wing slide for a Boeing 777-300 aircraft comprises a rectangular support frame and a curved inner liner matching the curved surface shape of a slide packaging box, wherein the curved inner liner is fixed above the support frame, and both sides of the curved inner liner are open structures, and rotatable stoppers are arranged on the outer edges of both sides of the curved inner liner.
[0006] The support frame of the utility model is rectangular and can be provided with four support legs, which is convenient for forklift transportation. The two sides of the support frame are open, which is convenient for quickly placing the packaging box connected to the slide into the support device. When the slide is packed, the packaging box can be matched and placed on the curved inner liner to keep the packaging box in a horizontal state, and the packaging box is clamped from both sides by the stopper to stabilize its position.
[0007] The utility model also has the following preferred designs:
[0008] The surface of the curved inner container of the utility model is paved with an anti-wear sponge layer, which can protect the packaging box and prevent it from being worn or impacted.
[0009] The stopper of the utility model can rotate 90 degrees, so that the stopper can be rotated from a horizontal state to a vertical state for fixing the slide packaging box, which can facilitate the fixing and removal of the packaging box.
[0010] The outer edges of both sides of the curved inner container of the utility model are both provided with two stoppers.
[0011] The curved inner container of the utility model is integrally formed on the supporting frame.
[0012] The utility model has the following beneficial effects:
[0013] 1. The support frame of the utility model is rectangular and can be provided with four support legs, which is convenient for forklift handling. The two sides of the support frame are open, which is convenient for quickly placing the packaging box connected to the slide into the support device. When the slide is packed, the packaging box can be placed on the curved inner liner in a matching manner to keep the packaging box in a horizontal state, and the packaging box is clamped from both sides by blocks to stabilize its position.
[0014] 2. The sponge layer laid on the surface of the curved inner liner of the utility model can protect the packaging box and prevent it from being worn or impacted. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 The utility model is a stereoscopic diagram of a supporting device for facilitating the packing of a large wing slide of a Boeing 777-300 aircraft.
[0016] Explanation of the accompanying drawings: 1-support frame, 2-curved inner liner, 3-stopper. DETAILED DESCRIPTION
[0017] The technical solution of the present utility model is described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can better understand and implement the technical solution of the present utility model.
[0018] like Figure 1 As shown, a supporting device for facilitating the packaging of a Boeing 777-300 aircraft large wing slide comprises a rectangular supporting frame 1, and also comprises a curved inner liner 2 matching the curved surface shape of the slide packaging box, the curved inner liner 2 is fixed above the supporting frame 1, and both sides of the curved inner liner 2 are open structures, and rotatable blocks 3 are provided on the outer edges of both sides of the curved inner liner 2.
[0019] As a preferred embodiment:
[0020] The surface of the curved inner liner 2 is paved with an anti-wear sponge layer, which can protect the packaging box from wear and impact.
[0021] The stopper 3 can be rotated by 90°, so that the stopper 3 can be rotated from a horizontal state to a vertical state for fixing the slide packaging box, which can facilitate fixing and removing the packaging box.
[0022] Two stoppers 3 are provided on both outer edges of the curved inner container 2 .
[0023] In this embodiment, the curved inner container 2 is integrally formed on the supporting frame 1 .
[0024] The support frame 1 of the utility model is rectangular and can be provided with four support legs, which is convenient for forklift transportation. The two sides of the support frame 1 are open, which is convenient for quickly placing the packaging box connected to the slide into the support device. When the slide is packed, the packaging box can be matched and placed on the curved inner liner 2 to keep the packaging box in a horizontal state, and the packaging box is clamped from both sides by the stopper 3 to stabilize its position.
[0025] The above embodiments are only preferred embodiments of the utility model, but cannot be used as limitations of the utility model.
