Description

Technical Field

[0001] This utility model relates to the field of aircraft ground support equipment technology, specifically a folding integrated bracket for helicopters. Background Technology

[0002] Traditional helicopter brackets are mostly fixed structures, such as some simple flat brackets, which are simple in structure and cannot be folded.

[0003] This type of bracket presents several inconveniences in use. Firstly, due to its non-foldable nature, it occupies a significant amount of space when not in use. Whether stored inside the helicopter cabin or in a maintenance area, it requires considerable space, resulting in a significant waste of space in the limited space of helicopter interiors and maintenance areas. Secondly, during transportation, the fixed structure of the bracket is difficult to move and store, potentially requiring a large transport space and increasing transportation costs. Utility Model Content

[0004] The purpose of this invention is to provide a folding integrated bracket for helicopters to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A folding integrated bracket for helicopters, including

[0007] Pallet 1 and Pallet 2 are arranged side by side, and each of them has a movable support leg below its opposite side.

[0008] A folding mechanism is provided below the same side of the pallet 1 and pallet 2;

[0009] A fixing mechanism is provided between the support leg and the folding mechanism.

[0010] Preferably, the folding mechanism includes a rod seat, with several rod seats arranged side by side at the bottom center of the first tray, a support rod movably sleeved in the center of the rod seat, and a fixed seat provided below the side of the second tray near the first tray, with a through hole matching the support rod in the center of the fixed seat.

[0011] Preferably, a retaining ring is provided on the outer side of the middle part of the support rod, and a spring is provided between the retaining ring and the rod seat located outside the support rod;

[0012] Preferably, a fixing frame is further provided below the side of the first tray away from the second tray, and a handle is movably installed inside the fixing frame, the handle being fixedly connected to the support rod;

[0013] Preferably, the fixing mechanism includes a flipping frame, with flipping frames provided at both ends below the opposite side of the first and second trays. The top of the support leg is movably connected to the flipping frame, and a positioning hole matching the support rod is provided at the center of the bottom end of the support leg.

[0014] Preferably, sliding grooves are provided at both ends of the side of the first tray near the second tray, and movable blocks matching the sliding grooves are provided at both ends of the side of the second tray near the first tray.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This is a folding integrated bracket for helicopters. The unfolding operation of this device is simple and convenient. When in use, simply pull the handle below the first tray to retract the support rod and compress the spring. Then, flip the first tray and the second tray to a horizontal angle. After releasing the handle, the spring rebounds and inserts the support rod into the fixed seat to complete the unfolding and support of the tray. The above operation does not require complicated tools or multiple people to cooperate. It can be easily completed by a single person, which improves work efficiency.

[0017] 2. This helicopter folding integrated bracket offers two folding states. The first state involves folding the two legs until they are level with tray one and tray two. During operation, the folding and positioning of the legs are achieved by controlling the extension and retraction of the support rod via a handle. The second state involves flipping and folding tray one and tray two, and then flipping and folding the two legs to form an "M" shape. The two folding methods can be selected according to the actual usage scenario and storage and transportation requirements. For example, the first folding method can be selected in places with relatively narrow spaces, while the second folding method can be selected when there are special requirements for the shape of the space, thus increasing the applicability of the bracket.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution:

[0026] A folding integrated bracket for helicopters includes a first bracket 1 and a second bracket 2, which are arranged side by side. Support legs 3 are movably arranged on the lower side of opposite sides of the first bracket 1 and the second bracket 2. A fixing mechanism is provided between the support legs 3 and the folding mechanism. The fixing mechanism includes a flipping frame 12. Flipping frames 12 are provided at both ends on the lower side of opposite sides of the first bracket 1 and the second bracket 2. The top of the support leg 3 is movably connected to the flipping frame 12. A positioning hole 13 matching the support rod 5 is opened in the middle of the bottom end of the support leg 3.

[0027] In this embodiment, the unfolding operation of this device is simple and convenient. When in use, simply pull the handle 11 below the tray 1 to retract the support rod 5 and compress the spring 9. Then, flip the tray 1 and tray 2 to a horizontal angle. After releasing the handle 11, the spring 9 rebounds and inserts the support rod 5 into the fixed seat 6 to complete the unfolding support of the tray. The above operation does not require complicated tools or multiple people to cooperate. It can be easily completed by a single person, which improves work efficiency.

[0028] like Figure 4 and Figure 5As shown, a folding mechanism is provided below the same side of pallet 1 and pallet 2. The folding mechanism includes a rod seat 4. Several rod seats 4 are arranged side by side in the middle of the bottom end of pallet 1. A support rod 5 is movably sleeved in the middle of the rod seat 4. A fixed seat 6 is provided below the side of pallet 2 near pallet 1. A through hole 7 matching the support rod 5 is provided in the middle of the fixed seat 6. A retaining ring 8 is also provided on the outer side of the middle of the support rod 5. A spring 9 is provided between the retaining ring 8 and the rod seat 4 located outside the support rod 5. A fixing frame 10 is further provided below the side of pallet 1 away from pallet 2. A handle 11 is movably installed inside the fixing frame 10. The handle 11 is fixedly connected to the support rod 5. Sliding grooves 14 are provided at both ends of the side of pallet 1 near pallet 2. Movable blocks 15 matching the sliding grooves 14 are provided at both ends of the side of pallet 2 near pallet 1.

[0029] In this embodiment, the device provides two folding states. The first state is to fold the two legs 3 until they are level with the tray 1 and tray 2. During operation, the extension and retraction of the support rod 5 is controlled by the handle 11 to achieve the folding and positioning of the legs 3. The second state is to flip and fold the tray 1 and tray 2, and then flip and fold the two legs 3 to form an "M" shape. The two folding methods can be selected according to the actual use scenario and storage and transportation requirements. For example, the first folding method can be selected in places with relatively narrow space, while the second folding method can be selected when there are special requirements for the shape of the space, which increases the applicability of the bracket.

[0030] Working principle: In use, tray 1 and tray 2 can be unfolded to a horizontal angle to support helicopter parts. When unfolding, pull the handle 11 below tray 1. Handle 11 retracts the support rod 5 and compresses the spring 9. Then, flip tray 1 and tray 2 to a horizontal angle. Release handle 11; the spring 9 rebounds, causing the support rod 5 to insert into the fixed base 6, thus providing support under tray 1 and tray 2. Next, flip the two support legs 3 downwards until the angle between the support legs 3 and the ground is 80°. It is supported on the ground in a figure-eight shape. When folded for storage, it can be used in two states. First, fold the two support legs 3 until they are level with the tray 1 and tray 2. When operating, pull the handle 11 to retract the support rod 5 from the fixed seat 6, then flip the support legs 3 to abut against the tray 1 and tray 2, and then release the handle 11 so that the support rod 5 successively fits the left support leg 3, the fixed seat 6 and the right support leg 3. Second, flip and fold the tray 1 and tray 2, and then flip and fold the two support legs 3 to form an "M" shape.
