Description
Technical Field
[0001] This utility model relates to the technical field of rescue aircraft accessories, specifically to a stable support bracket for a fire emergency rescue aircraft. Background Technology
[0002] In fire emergency rescue operations, time is of the essence. As a rapid response rescue tool, the efficiency with which aircraft carry rescue supplies directly impacts the rescue progress. However, the current connection structure between the support frame and the rescue supply basket of fire emergency rescue aircraft has many problems. Traditional connection methods mostly rely on fasteners such as bolts and nuts. During installation, operators need to align the bolt holes one by one and tighten the bolts. This is not only cumbersome, but also prone to installation errors due to panic in emergency situations, significantly extending the rescue preparation time. Although some structures use snap-fit connections, the limiting method of the snap-fit is simple, achieving fixation only through a single locking point. During takeoff, landing, and flight, the snap-fit is prone to loosening or even falling off due to airflow disturbances and fuselage vibrations, causing rescue supplies to fall and seriously affecting the rescue mission.
[0003] Furthermore, the connection points between the rescue supply basket and the support frame are often concentrated on one side or in a localized location, resulting in uneven stress on the basket after it carries supplies. This makes it prone to tilting to one side, which not only increases the aircraft's drag and affects flight stability but may also damage the connection between the basket and the support frame due to concentrated stress. This further reduces the safety and reliability of the rescue process. At the same time, traditional structures are also time-consuming to disassemble and replace the rescue supply basket, making it difficult to meet the needs of frequently changing different types of rescue supplies in fire rescue, thus restricting the flexibility and efficiency of rescue work. Therefore, a stable support frame for fire emergency rescue aircraft is proposed. Utility Model Content
[0004] This utility model proposes a stable support bracket for fire emergency rescue aircraft. Through the insertion and cooperation of the insertion block and the placement frame, combined with the elastic push of the first limiting block by the first spring in the moving groove, the first limiting block can be quickly inserted into the empty grooves on both sides of the placement frame, realizing the rapid fixation of the rescue material placement basket to the aircraft support bracket. This eliminates the cumbersome tool operation steps in the traditional connection method and effectively shortens the rescue preparation time. The array of first springs is evenly distributed along the length of the moving groove, providing uniform elastic force to the first limiting block. Combined with the symmetrical arrangement of the first limiting block, it ensures that the insertion block is subjected to balanced force within the placement frame, avoiding the tilting problem caused by a single limiting block.
[0005] According to one aspect, at least one embodiment of the present invention provides a stable support bracket for a fire emergency rescue aircraft, comprising: an aircraft support bracket, wherein a placement frame is welded and fixed on the aircraft support bracket, an insertion block is inserted inside the placement frame, and a rescue material placement basket is fixedly connected to one end of the insertion block; the insertion block has a movable groove inside, a first limiting block is movably disposed in the movable groove, and a first spring is disposed inside the movable groove, one end of the first spring being fixedly connected to the first limiting block.

[0012] For example, at least one embodiment of this utility model provides a stable support bracket for a fire emergency rescue aircraft, which further includes: the third limiting block is symmetrically arranged on the aircraft support bracket.
[0013] The working principle and beneficial effects of this utility model are as follows: By inserting the insertion block and the placement frame component, combined with the elastic push of the first spring on the first limiting block in the moving groove, the first limiting block can be quickly inserted into the empty grooves on both sides of the placement frame component, realizing the rapid fixation of the rescue material placement basket and the aircraft support bracket. This eliminates the cumbersome tool operation steps in the traditional connection method and effectively shortens the rescue preparation time. The array of first springs is evenly distributed along the length of the moving groove, providing uniform elastic force to the first limiting block. Combined with the symmetrical arrangement of the first limiting block, it ensures that the insertion block is subjected to balanced force within the placement frame component, avoiding the tilting problem caused by a single limiting block. The rubber coating on the surface of the first limiting block increases the friction with the inner wall of the empty groove, further improving the stability of the locking state and preventing loosening due to vibration during aircraft flight.

[0026] Refer to the instruction manual appendix Figure 1-4A stable support bracket for a fire emergency rescue aircraft includes an aircraft support bracket 1. A placement frame 2 is welded and fixed to the aircraft support bracket 1. An insertion block 4 is inserted inside the placement frame 2. One end of the insertion block 4 is fixedly connected to a rescue material placement basket 3. The insertion block 4 has a movable groove 5 inside. A first limiting block 6 is movably set in the movable groove 5. A first spring 7 is installed inside the movable groove 5. One end of the first spring 7 is fixedly connected to the first limiting block 6. By installing the insertion block 4 on the placement frame 2, the rescue material placement basket 3 can be quickly fixed to the aircraft support bracket 1, saving the installation and fixing process and reducing rescue preparation time.
[0027] The insert block 4 has a movable groove 5 inside, which is a rectangular groove. A first limiting block 6 is movably mounted in the movable groove 5. The shape of the first limiting block 6 matches the movable groove 5 and can slide flexibly inside the movable groove 5. A first spring 7 is installed inside the movable groove 5. One end of the first spring 7 is fixedly connected to the first limiting block 6, and the other end is fixedly connected to the inner wall of the movable groove 5. An array of first springs 7 is installed inside the movable groove 5. The array of first springs 7 is evenly distributed along the length of the movable groove 5 and can provide uniform elastic force to the first limiting block 6. The outer end of the first limiting block 6 is inserted into the empty grooves on both sides of the placement frame 2. The size of the empty grooves is adapted to the size of the outer end of the first limiting block 6 to ensure a tight fit between the two. The above structure allows the first limiting block 6 to be engaged in the empty groove on the side of the placement frame 2 when the insert block 4 and the placement frame 2 are in a snap-fit state, achieving a limiting and fixing effect.
[0028] The first limiting block 6 is symmetrically arranged on the insertion block 4. This symmetrical structure can make the insertion block 4 evenly stressed within the placement frame 2, avoiding tilting of the insertion block 4 due to unbalanced forces. The outer surface of the first limiting block 6 is provided with a rubber coating with fine anti-slip texture. The rubber coating can effectively improve the friction of the first limiting block 6 near the slot, preventing the first limiting block 6 from falling out of the slot due to vibration during aircraft flight.
[0029] One end of the insertion block 4 is fixedly connected to a straight rod 8, which is cylindrical in shape. A rotating rod 9 is slidably connected to the straight rod 8, and a second limiting block 10 is rotatably connected to the rotating rod 9. The side of the second limiting block 10 that is in contact with the outer wall of the placement frame 2 is provided with anti-slip texture. A second spring 11 is wound around the outside of the straight rod 8. One end of the second spring 11 is fixedly connected to the rotating rod 9, and the other end of the second spring 11 is fixedly connected to the straight rod 8. When the first limiting block 6 is in a snap-fit state with the placement frame 2, the second limiting block 10 will rotate around the straight rod 8 using the rotating rod 9. When the second limiting block 10 is partially in contact with the surface of the placement frame 2, the elasticity of the second spring 11 will cause the second limiting block 10 to clamp the placement frame 2, increasing the friction and achieving the effect of reinforcement and limitation.
[0030] One end of the aircraft support bracket 1 is provided with a slide groove 12, which is a T-shaped groove structure. A slider 13 is slidably connected inside the slide groove 12. The shape of the slider 13 matches the slide groove 12, allowing it to slide smoothly inside the slide groove 12. The bottom end of the slider 13 is fixedly connected to the rescue material placement basket 3 by welding to ensure the connection is firm. Since the mounting block 4 is fixed to the placement frame 2 only at one end of the rescue material placement basket 3, in order to maintain the balance of weight, the slider 13 on the rescue material placement basket 3 will slide and connect to the slide groove 12 on the other side of the aircraft support bracket 1, thereby achieving the effect of balancing the weight of the rescue material placement basket 3.
[0031] The slider 13 has a movable groove 14 inside, which is a cylindrical groove with its axis perpendicular to the axis of the slider 13. A third limiting block 16 is movable inside the movable groove 14. One end of the third limiting block 16 is a hemispherical structure, which facilitates insertion and disengagement from the limiting groove 15. The aircraft support bracket 1 has a limiting groove 15, which is evenly distributed along the length of the slide 12. Its size is adapted to the third limiting block 16. The third limiting block 16 passes through the movable groove 14 and is inserted into the limiting groove 16. Inside the movable groove 14, a third spring 17 is provided. One end of the third spring 17 is fixedly connected to the third limiting block 16, and the other end is fixedly connected to the inner wall of the movable groove 14. Pressing the third limiting block 16 causes it to disengage from the limiting groove 15, thereby releasing the slider 13 from the sliding groove 12. Conversely, the third limiting block 16 is inserted into the limiting groove 15 by utilizing the elastic properties of the third spring 17, thereby fixing the slider 13 on the sliding groove 12.
[0032] The third limiting block 16 is symmetrically arranged on the aircraft support bracket 1. This symmetrical arrangement can make the force on the slider 13 in the slide groove 12 more balanced, further improving the stability of the rescue material placement basket 3. The above structure, through multiple limiting and fixing methods, fixes and balances the rescue material placement basket 3 from different angles, improving the stability of the equipment and ensuring that rescue materials can be safely and stably transported to the rescue location with the aircraft during fire emergency rescue.
[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
