A fighter jet model's front landing gear

Abstract

This utility model relates to the field of model aircraft technology and discloses a front landing gear for a fighter jet model, including an elongated cover. Hinges are rotatably connected to the front and rear sides of the outer wall of the elongated cover. An elongated block is fixedly connected to the top of each hinge. A housing is engaged between two adjacent elongated blocks. A rotating rod is rotatably connected to the right inner end of the housing. A diagonal rod is fixedly connected to the other end of the rotating rod. The bottom end of the diagonal rod passes through the top of the elongated cover and is rotatably connected to a rotating shaft. In this utility model, the elongated blocks fixedly connected to the hinges engage with the outer wall of the housing. When pressure is applied to the housing, the elongated rod is pressed downwards, simultaneously causing the sliding wheel to move downwards. This, in conjunction with the hollow ring, causes the reciprocating connecting plate to extend downwards along the outer wall of the elongated rod. Consequently, the sliding wheel reduces impact during descent and provides effective cushioning, facilitating daily use by operators.

Description

Technical Field

[0001] This utility model relates to the field of model aircraft technology, and in particular to a front landing gear for a fighter jet model. Background Technology

[0002] The nose landing gear of a fighter jet model is a crucial load-bearing and support component in the entire airframe structure. Located at the front of the fuselage, the nose landing gear is responsible for supporting the weight of the front and maintaining the directional stability of the aircraft during ground taxiing. Its built-in steering mechanism also allows the aircraft to turn flexibly during taxiing. For a model, a detailed nose landing gear must not only accurately reproduce the structural form of the real aircraft, including the struts, tires, and shock absorption structure details, but also ensure that its connection with the main fuselage is stable and can withstand the corresponding stress during model display or simulated operation. At the same time, its retraction and extension movements must be smooth and reliable. It is an important part of reflecting the model's manufacturing craftsmanship and the degree of simulation.

[0003] With the continuous innovation and development of model making technology, the materials and processes for making the nose landing gear of fighter jet models are also constantly being upgraded, from simple hand-made to precision CNC machining. These advancements have not only improved the strength and durability of the nose landing gear, making it lighter, but also helped to improve the overall flight performance of the model. The nose landing gear of fighter jet models has become a technological hotspot in the field of model making, attracting many enthusiasts to continuously explore and innovate, and pushing the level of fighter jet model making to a higher level. Secondly, in the process of using the existing nose landing gear of fighter jet models, the wheels connected to the landing gear do not have effective reciprocating and cushioning effects, which makes it easy for impact forces to affect the service life and lifespan of the landing gear, thus making it inconvenient to use and reducing its efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a fighter jet model front landing gear, which aims to improve the problem that the wheels connected to the landing gear in the existing fighter jet model front landing gear do not have effective reciprocating and buffering functions during use, resulting in the impact force easily affecting the service life and lifespan of the landing gear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fighter jet model front landing gear, comprising an elongated cover, with hinges rotatably connected to the front and rear sides of the outer wall of the elongated cover, an elongated block fixedly connected to the top of the hinge, a housing engaged between two adjacent elongated blocks, a rotating rod rotatably connected to the inner right end of the housing, a diagonal rod fixedly connected to the other end of the rotating rod, a rotating shaft rotatably connected to the bottom end of the diagonal rod penetrating the top of the elongated cover, an elongated rod fixedly connected to one side of the rotating shaft, a hollow ring slidably connected to the bottom of the outer wall of the elongated rod, a reciprocating connecting plate rotatably connected to the outer wall of the hollow ring, a sliding wheel rotatably connected to the other end of the reciprocating connecting plate, and a fixed connection between the top center of the sliding wheel and the bottom end of the elongated rod.

[0006] As a further description of the above technical solution: The top end of the elongated rod is rotatably connected to a long rod, and the outer wall of the long rod is rotatably connected to an L-shaped plate. The outer wall of the L-shaped plate is fixedly connected to the inner left end of the outer shell.

[0007] As a further description of the above technical solution: A long plate is fixedly connected to the top right side of the outer casing.

[0008] As a further description of the above technical solution: The top left and right sides of the outer casing are each fixedly connected with a reserved ring.

[0009] As a further description of the above technical solution: The front and rear sides of the outer wall of the long rod engage with the bottom left side of the outer casing.

[0010] This utility model has the following beneficial effects: 1. In this utility model, the elongated cover is connected to the hinge, and the elongated block fixedly connected to the hinge engages with the outer wall of the outer shell. When the outer shell is subjected to pressure, the elongated rod is pressed down, which in turn drives the sliding wheel to move down. This, in conjunction with the hollow ring, causes the reciprocating connecting plate to extend downward along the outer wall of the elongated rod. As a result, the sliding wheel reduces the impact force when it falls, and also has an effective buffering effect, making it convenient for operators to use in daily life.

[0014] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides: a fighter jet model front landing gear, including an elongated cover 3, with hinges 11 rotatably connected to the front and rear sides of the outer wall of the elongated cover 3, an elongated block 10 fixedly connected to the top of the hinge 11, a shell 1 engaging between two adjacent elongated blocks 10, a rotating rod 12 rotatably connected to the inner right end of the shell 1, a diagonal rod 15 fixedly connected to the other end of the rotating rod 12, a rotating shaft 4 rotatably connected to the bottom end of the diagonal rod 15 through the top of the elongated cover 3, an elongated rod 8 fixedly connected to one side of the rotating shaft 4, a hollow ring 7 slidably connected to the bottom of the outer wall of the elongated rod 8, a reciprocating connecting plate 5 rotatably connected to the outer wall of the hollow ring 7, a sliding wheel 6 rotatably connected to the other end of the reciprocating connecting plate 5, and a fixed connection between the top middle of the sliding wheel 6 and the bottom end of the elongated rod 8; Specifically, the bottom end of the diagonal rod 15 passes through the top of the elongated cover 3 and is rotatably connected to the rotating shaft 4 at this point. The bottom of the outer wall of the elongated rod 8 is slidably connected to the hollow ring 7, and the outer wall of the hollow ring 7 is rotatably connected to the reciprocating connecting plate 5. The reciprocating connecting plate 5 rotates and swings back and forth as the hollow ring 7 slides. The other end of the reciprocating connecting plate 5 is rotatably connected to the sliding wheel 6, which can slide and convert the swinging motion of the reciprocating connecting plate 5 into linear sliding motion, thereby realizing the conversion and transmission of different motion forms.

[0015] Please see the appendix Figure 3 - Appendix Figure 5A long plate 2 is fixedly connected to the top right side of the outer shell 1. A long rod 13 is rotatably connected to the top of the long rod 8. An L-shaped plate 14 is rotatably connected to the outer wall of the long rod 13. The outer wall of the L-shaped plate 14 is fixedly connected to the inner left side of the outer shell 1. The front and rear sides of the outer wall of the long rod 13 are engaged with the bottom left side of the outer shell 1. Reserved rings 9 are fixedly connected to the top of both the left and right sides of the outer shell 1. Specifically, by being closely connected to the long rod 13, it is ensured that the long rod 13 can rotate flexibly around the top of the long rod 8, and the connection is also ensured to be stable. In addition, the left and right top sides of the outer shell 1 are respectively fixedly connected with reserved rings 9. The reserved rings 9 are in the shape of a ring and are evenly distributed on both sides of the top of the outer shell 1, ensuring that the long rod 13 will not be displaced or shaken during the operation of the model machine, thereby ensuring the overall stability and reliability.

[0016] Working principle: First, the elongated cover 3 is connected to the hinge 11. The elongated block 10, which is fixedly connected to the hinge 11, engages with the outer wall of the outer casing 1. When the outer casing 1 is subjected to pressure, the inclined rod 15 connected to the rotating rod 12, in conjunction with the rotating shaft 4, presses the elongated rod 8 downward. At the same time, it drives the sliding wheel 6 to move downward. This, in conjunction with the hollow ring 7, causes the reciprocating connecting plate 5 to extend downward along the outer wall of the elongated rod 8. This reduces the impact force on the sliding wheel 6 when it falls, and provides effective cushioning, making it convenient for operators to use in daily life.
