Description

Technical Field

[0001] The present invention belongs to the field of aircraft equipment storage and loading, and relates to an adjustable bolster for aircraft external equipment, specifically to a storage bolster for a certain external equipment of an aircraft. Background Art

[0002] After a certain type of launch device of a certain model of aircraft is removed from the aircraft, it needs to be placed in a shelter or storage rack for storage. The existing storage of external equipment is simple and usually directly placed on the rack. Due to the irregular size and shape of the external equipment, the existing storage method is prone to falling, and it cannot be placed quickly and labor-savingly. It cannot adjust the width according to the actual size, cannot ensure the firm and stable placement of the external equipment, and is easy to wear. Summary of the Invention

[0003] The present invention provides an adjustable bolster for aircraft external equipment, which can be installed on a shelter trolley or a fixed rack for use, ensuring that when storing the external equipment, the width of the two side blocks can be adjusted according to the actual size, and ensuring that the external equipment is firm, stable and not easy to wear during storage.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] An adjustable bolster for aircraft external equipment, the adjustable bolster includes a bolt connecting plate 1, a bottom support 2, side blocks 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-shaped support block with an n-shaped cross-section, and its top surface is provided with two pairs of strip-shaped mounting holes for installing the side blocks 3 so that their installation positions can be adjusted. At both ends of the bottom of the bottom support 2, bolt connecting plates 1 are welded for fixing and installing on the external equipment trolley through bolts; a polyurethane pad B 5 is installed on the upper surface of the bottom support 2 to avoid wearing the paint surface of the aircraft external equipment.

[0007] The lower part of the side block 3 is welded with an upper block 7, and two bolt holes are made on the upper block 7. The side blocks 3 are used in pairs and 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 fixed connection is achieved through an internal hexagonal socket head bolt. By adjusting the installation position of the side block 3 on the bottom support 2, the distance between the two side blocks 3 is adjusted to suit external equipment of different sizes; a lower block 6 is padded at the lower surface of the bottom support 2, that is, under the internal hexagonal socket head bolt, to enhance the connection strength; polyurethane pads A 4 are installed on the opposite surfaces of the two side blocks 3 to avoid wearing the paint surface of the aircraft external equipment; pin holes are made at the tops of the two side blocks 3 for inserting the stainless steel pin 8 to fasten the external equipment through a strap.

[0008] At least two of the adjustable bolsters are used simultaneously and are bolt-connected to the external equipment trolley through the bolt connecting plate 1.

[0009] The adjustable headrest described above is formed by welding 7-series aviation aluminum, which ensures strength while reducing weight.

[0010] Advantages of the present invention: The structure of the present invention is simple and practical, solving the problems in the prior art such as inability to place quickly and labor-savingly, inability to adjust the width according to actual dimensions, unstable placement, easy wear, and heavy weight. It has high practicability, convenience, accuracy, and safety, and can also reduce the safety risks brought by accidental dropping. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the following will describe in detail the specific embodiments of the present invention according to the technical solutions.

[0023] An adjustable pillow for an aircraft external hanging device, as Figures 1 to 3 shown, the adjustable pillow includes a bolt connecting plate 1, a bottom support 2, side blocks 3, a polyurethane pad A 4, a polyurethane pad B 5, a lower block 6, an upper block 7, and a stainless steel pin shaft 8.

[0024] As Figure 5 shown, the bottom support 2 is a strip-shaped support block with an n-shaped cross-section, and two pairs of strip-shaped mounting holes are provided on its top surface for mounting the side blocks 3 so that their mounting positions can be adjusted. At both ends of the bottom of the bottom support 2, bolt connecting plates 1 are welded (as Figure 4 shown), for fixed installation on the trolley of the external hanging device through bolts; a polyurethane pad B 5 is installed on the upper surface of the bottom support 2 through cross-recessed head screws (as Figure 8 shown) to avoid scratching the paint surface of the aircraft external hanging device.

[0025] As Figure 6 shown, the side blocks 3 are vertically placed U-shaped blocks, and an upper block 7 is welded to the lower part inside the U-shaped groove (as Figure 10 shown). Two bolt holes are made on the upper block 7 for mounting the side blocks 3 on the bottom support 2; the side blocks 3 are used in pairs, and the U-shaped grooves are symmetrically installed back to back 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 fixed connection is achieved through socket head cap screws. By adjusting the mounting positions of the side blocks 3 on the bottom support 2, the distance between the two side blocks 3 is adjusted to suit external hanging devices of different sizes; a lower block 6 is padded at the lower side of the socket head cap screw, that is, at the lower surface of the bottom support 2 (as Figure 9 shown) to enhance the connection strength; polyurethane pads A 4 are installed on the opposite surfaces of the two side blocks 3 through cross-recessed head screws (as Figure 7 shown) to avoid scratching the paint surface of the aircraft external hanging device; pin holes are relatively made at the tops of the U-shaped groove walls of the two side blocks 3 for inserting the stainless steel pin shaft 8 to fasten the external hanging device through a strap.

[0026] Three of the adjustable pillows are used simultaneously and installed at different positions on the trolley of the external hanging device through the bolt connecting plates 1.

[0027] The adjustable pillow is welded and formed by 7-series aviation aluminum, ensuring strength while also reducing weight.
