Description

Technical Field

[0001] This utility model belongs to the field of aircraft equipment storage and loading, and relates to an adjustable support pillow for aircraft external equipment, specifically a support pillow for storing a certain external equipment of an aircraft. Background Technology

[0002] After a certain type of launcher from a certain aircraft is removed from the aircraft, it needs to be stored in a container or storage rack. Existing storage methods for external equipment are simple, usually placing it directly on a rack. However, due to the irregular size and shape of the external equipment, the existing storage method makes it easy for it to fall, making it impossible to place it quickly and effortlessly. It is also impossible to adjust the width according to the actual size, and it is impossible to ensure that the external equipment is placed firmly and stably, and it is also prone to wear and tear. Utility Model Content

[0003] This utility model provides an adjustable support for aircraft external equipment, which can be installed on a container trolley or fixed frame. When storing external equipment, the width of the side blocks can be adjusted according to the actual size, ensuring that the external equipment is secure, stable and not easily worn.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An adjustable external mount for aircraft includes a bolted connecting plate 1, a bottom support 2, a side block 3, a polyurethane pad A 4, a polyurethane pad B 5, a lower block 6, an upper block 7, and a stainless steel pin 8.

[0006] The bottom support 2 is a strip support block with an n-shaped cross section. Its top surface is provided with two pairs of strip mounting holes for installing side blocks 3 so that the installation position can be adjusted. Bolt connecting plates 1 are welded to both ends of the bottom of the bottom support 2 for fixing the external equipment trolley with bolts. A polyurethane pad B 5 is installed on the upper surface of the bottom support 2 to avoid abrading the paint surface of the aircraft external equipment.

[0007] The lower part of the side block 3 is welded with an upper block 7, which has two bolt holes. The side blocks 3 are used in pairs and are symmetrically installed at both ends of the bottom support 2. The bolt holes on the upper block 7 are aligned with the strip-shaped mounting holes on the bottom support 2 and are fixedly connected by hexagonal head bolts. The distance between the two side blocks 3 can be adjusted by adjusting the installation position of the side blocks 3 on the bottom support 2 to accommodate external equipment of different sizes. A lower block 6 is placed on the lower surface of the bottom support 2 below the hexagonal head bolts to strengthen the connection. Polyurethane pads A 4 are installed on the opposite surfaces of the two side blocks 3 to prevent abrasion of the paint surface of the aircraft external equipment. The top of both side blocks 3 has pin holes for the insertion of stainless steel pins 8 to secure the external equipment with straps.

[0008] At least two adjustable support pillows can be used simultaneously and are bolted to the external equipment trolley via bolted connecting plate 1.

[0009] The adjustable support pillow is made of 7-series aerospace aluminum, which ensures strength while reducing weight.

[0010] The beneficial effects of this utility model are: The structure of this utility model is simple and practical, solving the problems of existing technologies such as the inability to place quickly and effortlessly, the inability to adjust the width according to the actual size, the instability and unstable placement, the easy wear and tear, and the heavy weight. It has high practicality, convenience, accuracy and safety, and can also reduce the safety risks caused by accidental drops. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below.

[0023] An adjustable headrest for aircraft external loads, such as Figures 1 to 3 The adjustable pillow includes a bolted connecting plate 1, a bottom support 2, a side block 3, a polyurethane pad A 4, a polyurethane pad B 5, a lower block 6, an upper block 7, and a stainless steel pin 8.

[0024] like Figure 5 The bottom support 2 is a strip-shaped support block with an n-shaped cross-section. Its top surface has two pairs of strip mounting holes for mounting side stops 3, allowing for adjustment of the mounting position. Bolt connecting plates 1 (such as...) are welded to both ends of the bottom of the bottom support 2. Figure 4 ), used for bolt-fixed installation on the external equipment trolley; the upper surface of the bottom support 2 is fitted with a polyurethane pad B 5 (such as) using Phillips head countersunk screws. Figure 8 To avoid damaging the paint on the aircraft's external equipment.
