Description

Technical Field

[0001] This utility model relates to the field of aircraft model maintenance equipment technology, and in particular to a flip-type bracket for the maintenance port of an aircraft model cabin spine. Background Technology

[0002] During the maintenance and debugging of large aircraft models, the maintenance port located on the ridge (top of the fuselage) is a key passage for accessing internal equipment.

[0003] Currently, maintenance personnel need to use external ladders and carry tools and parts by hand when working in this location. This is extremely inconvenient when performing operations in a certain position. Tools and parts have nowhere to be placed and are prone to slipping, which poses a risk of damaging the model, losing parts, and injuring personnel. In addition, their hands cannot be freed, which seriously affects maintenance efficiency and work safety.

[0004] There is a lack of a dedicated device in the current technology that can be directly integrated into the model cabin and provide a stable support platform at the ridge position. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a flip-type bracket for the maintenance opening of the ridge of an aircraft model cabin. This is a compact, easy-to-operate, and integrated aircraft model cabin ridge maintenance opening flip-type bracket that blends into the shape of the model when stored.

[0006] The purpose of this utility model is achieved through the following technical solution: a flip-type bracket for the maintenance port of an aircraft model cabin spine, comprising a tray, a hinge assembly, and a fixing assembly; a first connecting block is provided on one side of the tray; the hinge assembly is provided on one side of the tray; the fixing assembly is provided at one end of the hinge assembly, the fixing assembly comprising a fixing seat, the fixing seat having a C-shaped block structure, a fixing groove being provided on the fixing seat, a fixing block being provided in the fixing groove, a fixing block being provided on the inner sidewall of the fixing groove, a fixing rod being provided on the fixing seat, the fixing rod passing through the fixing seat and rotatably connected to the fixing block.

[0007] With its unique C-shaped mounting base and rotating clamping block design, the bracket can be installed and secured on the ridge maintenance port in seconds without tools, greatly improving equipment preparation efficiency.

[0008] The present invention is further configured such that: the fixing groove is provided with a groove capable of accommodating the fixing block, and the fixing rod is at least partially embedded in the fixing block for rotatable connection.

[0009] By embedding the fixing rod into the fixing block, the linear spiral motion of the fixing rod is converted into the rotational pressing motion of the fixing block, thus enabling quick installation and disassembly.

[0010] The present invention is further configured such that a third connecting block is provided on the side of the fixing block away from the fixing groove.

[0011] By setting a third connecting block on the fixed block, a stable and reliable mounting fulcrum is provided for the articulated assembly, ensuring a smooth force transmission path and effectively transferring the working load from the pallet to the fixed assembly and the model cabin structure.

[0012] The present invention is further configured such that: the hinge assembly includes a rotary connecting block and a second connecting block, one end of the second connecting block is provided with a stepped groove for embedded connection, and the other end is provided with a radial groove for hinge connection, the radial groove end of the second connecting block is hinged to the first connecting block, and the stepped groove end of the second connecting block is rotatably connected to the rotary connecting block.

[0013] By employing a composite hinge assembly consisting of a second connecting block and a rotating connecting block, multi-degree-of-freedom movement of the pallet relative to the fixed base is achieved. This not only allows the pallet to unfold and fold, but also allows for minute angle adjustments after unfolding to adapt to different working postures and operating habits, thus improving the flexibility of use.

[0014] The present invention is further configured such that: one end of the rotating connecting block is provided with a stepped disc that matches the stepped groove, and the stepped disc is inserted into the stepped groove and rotated.

[0015] The matching and embedding design of the stepped disc and the stepped groove forms a compact and load-bearing rotating shaft system. While ensuring smooth rotation, it effectively resists bending moment and torque from the tray, enhancing the structural rigidity and stability of the entire hinge mechanism.

[0016] This utility model has the following advantages: Through the unique design of the C-shaped fixing seat and the rotating clamping fixing block, the bracket can be installed and fixed on the ridge maintenance port in a few seconds without tools, which greatly improves the equipment preparation efficiency.

[0017] The multi-degree-of-freedom hinge assembly enables the pallet to flip, fold, and finely adjust its angle, allowing it to be flexibly positioned according to maintenance tasks and personnel posture, providing the best working space. Attached Figure Description

[0027] like Figure 1 As shown, a flip-type bracket for the maintenance opening of an aircraft model cabin spine includes a tray 1, a hinge assembly 2, and a fixing assembly 3.

[0028] A first connecting block 11 is provided on one side of the tray 1, and a groove for holding parts is provided on the top surface of the tray 1, with a silicone pad for anti-slip in the groove.

[0029] The hinge assembly 2 is located on one side of the tray 1; The fixing component 3 is located at one end of the hinge component 2. The fixing component 3 includes a fixing seat 31, which has a C-shaped block structure. The fixing seat 31 has a fixing groove 34, and a fixing block 35 is provided in the fixing groove 34. The fixing block 35 is provided on the inner side wall of the fixing groove 34. The fixing seat 31 has a fixing rod 36, which passes through the fixing seat 31 and is rotatably connected to the fixing block 35. Through the unique design of the C-shaped fixing seat 31 and the rotating pressing fixing block 35, the bracket can be installed and fixed in the ridge maintenance port in a few seconds without tools, which greatly improves the equipment preparation efficiency.

[0030] The fixing groove 34 is provided with a groove that can accommodate the fixing block 35, and the fixing rod 36 is at least partially embedded in the fixing block 35 for rotatable connection; by embedding the fixing rod 36 in the fixing block 35, the linear spiral motion of the fixing rod 36 is converted into the rotational pressing motion of the fixing block 35, realizing quick installation and disassembly.

[0031] In this embodiment, the fixing groove 34 is a through groove.

[0032] A third connecting block 32 is provided on the side of the fixing block 35 away from the fixing groove 34; by providing the third connecting block 32 on the fixing block 35, a stable and reliable mounting fulcrum is provided for the hinge assembly 2, ensuring the smooth force flow transmission path, and effectively transferring the working load from the tray 1 to the fixing assembly 3 and the model cabin structure.

[0033] like Figure 3 As shown, the third connecting block 32 is a cylindrical structure with a through groove at one end, and a chamfer is provided at one end of the through groove to facilitate rotation.

[0034] The fixing rod 36 and the fixing seat 31 are connected by a thread. The fixing seat 31 has a threaded hole, and the fixing rod 36 has an external thread on the outside.

[0035] A knob 37 is provided at the end of the fixing rod 36 away from the fixing block 35, and an anti-slip block 33 is provided on the side of the fixing groove 34 opposite to the fixing block 35. The anti-slip block 33 is made of silicone.

[0036] The hinge assembly 2 includes a rotating connecting block and a second connecting block 22. One end of the second connecting block 22 has a stepped groove for embedding the connection, and the other end has a radial groove for hinge. The radial groove end of the second connecting block 22 is hinged to the first connecting block 11, and the stepped groove end of the second connecting block is rotatably connected to the rotating connecting block. By using the composite hinge assembly 2 composed of the second connecting block 22 and the rotating connecting block, the multi-degree-of-freedom movement of the tray 1 relative to the fixed base 31 is realized. This not only allows the tray 1 to unfold and fold, but also allows it to make small angle adjustments after unfolding to adapt to different working postures and operating habits, thus improving the flexibility of use.

[0037] One end of the rotating connecting block is provided with a stepped disk that matches the stepped groove. The stepped disk is embedded in the stepped groove and rotates. Through the matching and embedding design of the stepped disk and the stepped groove, a compact and load-bearing rotating shaft system is formed. While ensuring smooth rotation, it effectively resists the bending moment and torque from the tray 1, thereby enhancing the structural rigidity and stability of the entire hinge mechanism.

[0038] Preferably, a positioning groove 23 is provided radially on the outer side wall of the first connecting block 11, the second connecting block 22 and the third connecting block 32, and a fixing sleeve 24 is also provided on the outer side wall of the first connecting block 11, the second connecting block 22 and the third connecting block 32.

[0039] Preferably, a number of evenly spaced positioning grooves 23 are provided on the outer side walls of the first connecting block 11, the second connecting block 22 and the third connecting block 32 along their circumference. When the rotating hinge block 21 is rotated to the designated position, the tray 1 can be steadily adjusted in direction. When the use is finished, the fixing sleeve 24 can be moved away from the joint part.

[0040] In this embodiment, there is at least one rotating connecting block, one second connecting block 22, and one positioning sleeve. This utility model has the following beneficial effects: With its unique C-shaped mounting bracket 31 and rotating clamping block 35 design, the bracket can be installed and fixed on the ridge maintenance port in seconds without tools, greatly improving equipment preparation efficiency.

[0041] The multi-degree-of-freedom hinge assembly 2 enables the tray 1 to flip, fold, and finely adjust its angle, allowing it to be flexibly positioned according to maintenance tasks and personnel posture, providing the best working space.

[0042] The overall mechanism is compact in design. When not in use, tray 1 can be completely folded up and close to the ridge of the cabin without taking up extra space and without affecting the aerodynamic shape of the model or its storage and transportation.

[0043] The force transmission path is clear, and the rigidity of each connection point is high, ensuring the stability of pallet 1 under load, effectively preventing tools and parts from slipping off, and ensuring the safety of maintenance operations.

[0044] The bracket structure is modularly designed and can be widely used in the maintenance of the spine of various types of aircraft models by adapting to the fixed seat 31 and tray 1 of different sizes.
