Description

Technical Field

[0001] The utility model relates to the technical field of aircraft workshop maintenance equipment, in particular to a new temporary storage rack for aircraft parts maintenance. Background Technique

[0002] In the aircraft workshop maintenance operation system, the parts maintenance rack, a key component storage device, is the core pillar to ensure the smooth progress of aircraft maintenance and repair work. After years of technological iteration and innovation, the design concept and core technology of this equipment have always closely followed the special needs of the aviation maintenance field and continued to be optimized and upgraded. In the technical system of the parts maintenance rack, the material selection is a key factor. Such racks are generally made of lightweight and high-strength materials, such as high-quality materials like aluminum alloy and high-quality steel. Thanks to these carefully selected materials, the racks not only have excellent durability and load-bearing performance but also maintain a light weight, making it convenient for maintenance personnel to move and adjust positions flexibly during operation. To fully exploit space potential and improve operation efficiency, the aircraft parts maintenance rack widely adopts a multi-layer structure design. This ingenious layout makes good use of the vertical space, enabling various maintenance parts to be stored in an orderly manner by category, which not only improves work efficiency but also makes the operation site cleaner and more orderly.

[0003] For example, a new temporary storage rack for aircraft parts maintenance with the publication (announcement) number of CN214446328U includes a base. Four shock-absorbing cylinders are fixedly connected to the bottom of the base. A limit column is fixedly connected to the inner top wall of the shock-absorbing cylinder. A first spring is sleeved outside the limit column. The bottom of the first spring is fixedly connected to a shock-absorbing block. The bottom of the shock-absorbing block is fixedly connected to a universal wheel. A rotating groove is opened at the top of the base. A rotating block is rotatably connected to the inside of the rotating groove. Card holes are opened on the left and right sides, front, and back of the base. A horizontal groove is opened on the right side of the rotating block. A second spring is fixedly connected to the left side wall of the horizontal groove. A spring piece is fixedly connected to the right side of the second spring. This aircraft parts maintenance rack can facilitate the movement of staff, improve stability at the same time, and facilitate the storage and retrieval of staff, and can adjust the direction at the same time.

[0004] In summary, the following technical problems exist in the prior art: In the above prior art and the currently available parts racks on the market, multiple components such as drawers and storage boxes are generally configured. Although the original intention is for classified storage, in actual operation, when multiple drawers or boxes are opened simultaneously, they often block each other. This not only increases the difficulty for maintenance personnel to quickly locate the required parts but also may cause the maintenance time to be unnecessarily extended, thereby affecting the overall maintenance efficiency. In addition, the design of the storage space of the existing parts rack, that is, the unfolding method of the drawer or storage box, makes most parts racks limited to a single-sided unfolding in a single direction. This design has certain limitations in actual use and is not conducive to maintenance personnel efficiently and quickly accessing parts. Especially in the case of emergency maintenance or when different parts need to be frequently replaced, this design may become a bottleneck restricting the improvement of maintenance efficiency. For this reason, we propose a new type of temporary storage rack for aircraft component maintenance. Summary of the Invention

An electric push rod is rotatably connected to one side inside the part placement cavity. The output end of the electric push rod is rotatably connected to the diamond plate. The middle of the diamond plate is rotatably connected to the part placement cavity. A matching component is assembled at one end of the diamond plate.

[0013] Preferably, the matching component includes a first rib rod, a second rib rod, a main elliptical triangular plate, a sub-elliptical triangular plate and a force-applying double round head rod. A first rib rod is rotatably connected to one end of the diamond plate. The connection point between the first rib rod and the output end of the electric push rod and the diamond plate is on the same axis.

Detailed Embodiment

[0024] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Embodiment 1

[0026] Referring to Figure 1 - Figure 2 , a novel temporary storage rack for aircraft component maintenance includes an upper layer rack 1 and a lower layer rack 2. The bottom of the upper layer rack 1 is provided with the lower layer rack 2, and the lower layer rack 2 is detachably connected to the bottom of the upper layer rack 1. A U-shaped base 3 is slidably connected to the inner side of the lower layer rack 2, and a flat base 4 is slidably connected to the inner side of the U-shaped base 3. Parts temporary storage drawers 5 are fixed to the tops of both the flat base 4 and the U-shaped base 3. A synchronous extension mechanism is assembled between the lower layer rack 2, the U-shaped base 3 and the flat base 4. The synchronous extension mechanism is used to gradually unfold the parts temporary storage drawers 5. The synchronous extension mechanism includes a toothed plate 6, a main gear 7, a vertical shaft 8 and a guiding component. Toothed plates 6 are fixed to both ends of the top of the flat base 4, and main gears 7 are meshed and connected to one side of each toothed plate 6. Vertical shafts 8 are fixed to the tops of the main gears 7, and the tops of the vertical shafts 8 are rotatably connected to the U-shaped base 3. A guiding component is assembled between the vertical shaft 8 and the lower layer rack 2.

[0027] The guiding component includes a secondary gear 9 and an L-shaped toothed rack 10. The tops of the vertical shafts 8 all penetrate through the U-shaped base 3 and are fixed with the secondary gears 9. Secondary gears 9 are meshed and connected to one side of each L-shaped toothed rack 10, and the L-shaped toothed racks 10 are all fixed to the lower layer rack 2. There is a gap between the bottom of the L-shaped toothed rack 10 and the U-shaped base 3, which will not cause movement interference to the movement of the U-shaped base 3.

[0028] An auxiliary mechanism is assembled between the U-shaped base 3 and the flat base 4, and the auxiliary mechanism is used to provide auxiliary prompts for the strokes of the U-shaped base 3 and the flat base 4. The auxiliary mechanism includes a cylindrical groove 11, a return spring 12, a movable connecting ball 13, and a hemispherical groove 14. Cylindrical grooves 11 are provided at both ends of the flat base 4, and a return spring 12 is fixed at one end inside each cylindrical groove 11. The return spring 12 is in clearance fit with the inner side of the cylindrical groove 11. A movable connecting ball 13 is fixed at one end of each return spring 12. The movable connecting ball 13 is slidably connected to the cylindrical groove 11. Two hemispherical grooves 14 corresponding to the positions of the movable connecting balls 13 are provided at both ends inside the U-shaped base 3. The hemispherical groove 14 is slidably connected to the movable connecting ball 13. When the flat base 4 is pulled outwards, since the hemispherical groove 14 is slidably connected to the movable connecting ball 13, the movable connecting ball 13 disengages from the inside of the first hemispherical groove 14 and compresses the return spring 12 to contract into the cylindrical groove 11. Then, when the flat base 4 is pulled further, when the movable connecting ball 13 contacts the second hemispherical groove 14, the elastic force generated by the return spring 12 at this time pushes the movable connecting ball 13 to move. When the maintenance personnel hears a "click" sound, that is, when the movable connecting ball 13 is connected to the second hemispherical groove 14, it means that the flat base 4 and the U-shaped base 3 have been pulled to the maximum distance.

[0029] Embodiment 2

[0030] Further optimization of Embodiment 1 is as follows. Specifically, as Figure 3 shown, a part placement cavity 15 is provided at the top of the upper shelf 1, a baffle 16 is fixed at the bottom inside the part placement cavity 15, and a vertical extension mechanism is assembled at the top of the part placement cavity 15.

[0031] The vertical extension mechanism includes a first top cover 17, a second top cover 18, an electric push rod 19, a diamond plate 20, and a matching component. The two ends of one side inside the part placement cavity 15 are respectively rotatably connected to the first top cover 17 and the second top cover 18. A tool rack is fixed on one side of each of the first top cover 17 and the second top cover 18. By utilizing the space inside the first top cover 17 and the second top cover 18, the storage capacity of the part rack is increased; the design of the tool rack helps the maintenance personnel to better classify and store tools, improving the accessibility and manageability of the tools; there is a gap between the mutually approaching ends of the first top cover 17 and the second top cover 18. An electric push rod 19 is rotatably connected to one side inside the part placement cavity 15. The output end of the electric push rod 19 is rotatably connected to the diamond plate 20. The middle of the diamond plate 20 is rotatably connected to the part placement cavity 15. A matching component is assembled at one end of the diamond plate 20. Through the setting of the baffle 16, when the first top cover 17 and the second top cover 18 are received to the horizontal position, a certain supporting effect can be provided for the first top cover 17 and the second top cover 18.

[0032] The cooperating components include a first rib rod 21, a second rib rod 22, a main elliptical triangular plate 23, a sub-elliptical triangular plate 24, and a force-applying double-round head rod 25. One end of the diamond plate 20 is rotatably connected to the first rib rod 21. The connection points of the first rib rod 21 and the output end of the electric push rod 19 with the diamond plate 20 are on the same axis. The other end of the diamond plate 20 is rotatably connected to the second rib rod 22. One end of the second rib rod 22 is rotatably connected to the main elliptical triangular plate 23. One end of the first rib rod 21 is rotatably connected to the sub-elliptical triangular plate 24. One end of the main elliptical triangular plate 23 is rotatably connected to the part placement cavity 15. At the other end of the main elliptical triangular plate 23 and near the second rib rod 22, there is a rotatable connection with the force-applying double-round head rod 25. One end of the sub-elliptical triangular plate 24 is rotatably connected to the part placement cavity 15. At the other end of the sub-elliptical triangular plate 24 and near the first rib rod 21, there is also a rotatable connection with the force-applying double-round head rod 25. One ends of the two force-applying double-round head rods 25 are respectively rotatably connected to the first top cover 17 and the second top cover 18. When the second rib rod 22 pulls or pushes the main elliptical triangular plate 23, the main elliptical triangular plate 23 can rotate along the connection with the part placement cavity 15. When the first rib rod 21 pulls or pushes the sub-elliptical triangular plate 24, the sub-elliptical triangular plate 24 can rotate along the connection with the part placement cavity 15.

[0033] From the above, it can be seen that:

[0034] The technical problem of the present utility model is as follows: In the prior art and current parts racks on the market, multiple drawers, storage boxes and other components are generally configured. Although the original intention is for classified storage, in actual operation, when multiple drawers or boxes are opened simultaneously, they often block each other, which not only increases the difficulty for maintenance personnel to quickly locate the required parts, but also may cause the maintenance time to be unnecessarily extended, thereby affecting the overall maintenance efficiency. In addition, the storage space design of the existing parts rack, that is, the unfolding method of the drawer or storage box, makes most parts racks limited to the single-sided unfolding in a single direction. This design has certain limitations in actual use and is not conducive to maintenance personnel to efficiently and quickly access parts. Especially in the case of emergency maintenance or frequent replacement of different parts, this design may become a bottleneck restricting the improvement of maintenance efficiency. The technical solutions of the above-mentioned various embodiments are adopted. At the same time, the implementation process of the above technical solutions is as follows:

[0035] During the use process, when it is necessary to take the parts in the part temporary storage drawer 5, pull the flat plate seat 4, so that the flat plate seat 4 drives the toothed plate 6 to move. Because the toothed plate 6 is meshed and connected with the main gear 7, the main gear 7 is fixed to the vertical shaft 8, and the vertical shaft 8 is rotatably connected to the U-shaped base 3. The sub-gear 9 is fixed to the vertical shaft 8, and the sub-gear 9 is meshed and connected with the L-shaped rack 10. Therefore, it can be made that the toothed plate 6 meshes with the main gear 7 to rotate, so that the vertical shaft 8 drives the sub-gear 9 to rotate, and then the flat plate seat 4 and the U-shaped base 3 respectively drive the part temporary storage drawer 5 to be unfolded step by step, facilitating the maintenance personnel to quickly find the parts in the part temporary storage drawer 5;

[0036] After that, start the electric push rod 19. The output end of the electric push rod 19 pushes the diamond plate 20 to rotate, thereby causing the diamond plate 20 to pull the first rib 21 to move and push the second rib 22 to move. Since the second rib 22 is rotatably connected to the main elliptical triangular plate 23 and the first rib 21 is rotatably connected to the auxiliary elliptical triangular plate 24, the auxiliary elliptical triangular plate 24 and the main elliptical triangular plate 23 can respectively push the force-applying double-round head rod 25 upward to move until the first top cover 17 and the second top cover 18 are unfolded, facilitating the maintenance personnel to quickly find the parts in the part placement cavity 15. At the same time, cooperating with the tool racks of the first top cover 17 and the second top cover 18, the maintenance efficiency is improved.

[0037] Through the above settings, this application will surely solve the above technical problems. At the same time, the following technical effects are achieved:

[0038] 1. The utility model adopts an innovative design of a synchronous extension mechanism, enabling the various part storage drawers 5 in the device to be arranged in a non-overlapping layout form, avoiding the problem of mutual occlusion. This design not only allows the maintenance personnel to directly observe the parts in all the opened part storage drawers 5, but also greatly simplifies the part search process, effectively reducing the time waste caused by blocked vision.

[0039] 2. Thanks to the unique design of the vertical extension mechanism of the utility model, on the basis of the horizontal expansion of the part storage drawers 5, the vertical opening of the storage space in the part placement cavity 15 is further realized, creating a new usage mode of two-way expansion in the horizontal and top directions. Combined with the tool racks configured on one side of the first top cover 17 and the second top cover 18, this design further improves the space utilization efficiency, enabling the maintenance personnel to quickly find and access the required parts and tools in a wider field of vision, thus significantly improving the efficiency of the maintenance work.
