Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, and in particular to a fixing tool for the main tire pressure sensor base of an A350 aircraft. Background Technology

[0002] In the aerospace industry, especially for the maintenance and upkeep of high-performance aircraft like the A350, the accurate installation and securing of the main tire pressure sensor is of paramount importance. As a crucial component of the aircraft tire monitoring system, the accuracy and stability of the tire pressure sensor directly affect flight safety and tire lifespan.

[0003] However, existing installation technologies generally have several problems. First, traditional installation methods often rely on manual operation, which not only requires highly skilled and experienced operators but is also prone to errors due to human factors. This manual approach is particularly inadequate under high-intensity flight conditions, making it difficult to guarantee accuracy and consistency in each installation. Second, existing installation tools often lack effective securing of the mounting base, leading to loosening or displacement of the base during tire pressure sensor installation, potentially causing safety hazards such as tire leaks. This not only seriously affects the normal operation of the aircraft but may also threaten the lives of passengers and crew.

[0004] Therefore, improving the accuracy and safety of the installation of the main tire pressure sensor base on the A350 aircraft has become a problem that needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, such as low installation accuracy and poor safety of the main tire pressure sensor base for the A350 aircraft, and to provide a fixing tool for the main tire pressure sensor base for the A350 aircraft.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] This utility model provides a fixing tool for the main tire pressure sensor base of an A350 aircraft, comprising a first plate-shaped element, a second plate-shaped element, and a fixing body connected in sequence. The first plate-shaped element and the second plate-shaped element form a first angle, and the second plate-shaped element and the fixing body form a second angle. The opening directions of the first angle and the second angle are opposite.

[0008] As a preferred technical solution, the fixing body includes a semi-enclosed sidewall and an opening formed by the semi-enclosed sidewall, and the semi-enclosed sidewall is connected to the second plate-shaped element.

[0028] Example:

[0029] This invention provides a fixing tool for the main tire pressure sensor base of an A350 aircraft. The fixing tool includes a first plate-shaped element, a second plate-shaped element, and a fixing body connected sequentially. The first plate-shaped element and the second plate-shaped element form a first angle, and the second plate-shaped element and the fixing body form a second angle. The opening directions of the first and second angles are opposite. In practical applications, by precisely designing and manufacturing this fixing tool according to the shape and dimensions of the A350 aircraft main tire pressure sensor base, the main tire pressure sensor base of the A350 aircraft can be effectively fixed, improving installation efficiency while ensuring accurate installation and stable operation of the tire pressure sensor.

[0030] Figure 1 A side view of one of the aforementioned fixing tools is shown. The fixing tool includes a first plate-shaped element 1, a second plate-shaped element 2, and a fixing body 3 connected in sequence. The first plate-shaped element 1 and the second plate-shaped element 2 form a first included angle α, and the second plate-shaped element 2 and the fixing body 3 form a second included angle β. The opening directions of the first included angle α and the second included angle β are opposite.

[0031] The design of each component will be described in detail below:

[0032] (1) First plate element 1

[0033] The first plate-shaped element 1 is used for gripping, i.e., the grip portion. This portion is designed according to ergonomic principles, allowing the operator to easily grip and control the tool, ensuring hand stability during operation and reducing operational errors caused by slippage. Specifically, the grip portion is designed with the operator's comfort and convenience in mind, ensuring hand stability and preventing slippage during operation. At the same time, the grip portion design also facilitates the application of even force by the operator, improving installation efficiency.

[0034] The grip section features a plate-like structure, which not only simplifies manufacturing and processing, reducing production costs, but also facilitates the later addition of a handle. This plate-like structure easily integrates with handles of various materials, including rubber, plastic, and metal, increasing grip stability and comfort. This design allows users to keep their hands relaxed even during extended periods of operation, reducing fatigue and improving the work experience. The length, width, and thickness of this section are designed according to the operator's hand shape and operating habits to ensure comfortable grip and stable operation. These dimensions can be adjusted as needed, but should always be within the bounds of ergonomic principles.

[0035] (2) Second plate element 2

[0036] The second plate-shaped element 2 is used to connect the first plate-shaped element 1 and the fixed body 3, i.e., the connecting part. This part acts as a bridge between the fixed body 3 and the gripping part, and adopts a precise structural design to ensure a stable connection between the two. Specifically, the connecting part uses high-strength connectors to ensure a firm and reliable connection between the fixed body 3 and the gripping part. This part has a simple design with no superfluous structures, which reduces the overall weight of the tool and improves its durability and reliability.

[0037] The connecting part also adopts a plate-like structure, which facilitates the integrated manufacturing of the tool and avoids stress concentration and reduced strength at the connection point that may occur during assembly and welding processes, while also ensuring the reliability and stability of the connection. The dimensions of this part are designed based on the dimensions of the fixing body 3 and the gripping part, as well as the connection method, to ensure a stable connection and reliable force transmission. The numerical range of these dimensions can be appropriately extended.

[0038] (3) Fixed main body 3

[0039] The mounting body 3, as the core of the mounting tool, is designed and manufactured strictly according to the precise dimensions and shape of the A350 aircraft's main tire pressure sensor base, ensuring a seamless fit to the base surface and providing a stable and reliable fixation. This part is made of high-strength, corrosion-resistant materials to cope with the complex and ever-changing aviation environment. Specifically, the mounting body 3 is made of high-strength, corrosion-resistant materials, and its shape and dimensions perfectly match the A350 aircraft's main tire pressure sensor base, forming a stable support structure that ensures it will not loosen due to external forces during installation.

[0040] like Figure 2 As shown, the fixing body 3 includes a semi-enclosed sidewall 31 and a U-shaped opening 32 formed by the semi-enclosed sidewall 31, which is connected to the second plate-shaped element 2. The shape of the U-shaped opening 32 is designed to more accurately fit the sensor base and provide stable support. Figure 2 The width d of the U-shaped opening 32 shown is 24.1 mm. In practical applications, the tolerance for the width d of the U-shaped opening 32 is ±1 mm, that is, the range of d is 24 to 24.2 mm. The dimensions of the opening width, length, width, and height of the fixing body 3 are precisely designed according to the corresponding dimensions of the sensor base to ensure a seamless fit. The numerical range of these dimensions is basically fixed and can be finely adjusted within the allowable error range.

[0041] The U-shaped opening not only takes into full account the sensor base configuration, ensuring precise alignment during installation, but also facilitates tool operation and use. The two side walls of the U-shaped opening 32 fit snugly against the edges of the sensor base, effectively preventing shifting or shaking during installation. Furthermore, this design allows users to operate in confined spaces, improving work efficiency and installation accuracy.

[0042] Furthermore, the relative angles between the various parts, namely the first included angle α and the second included angle β, are determined based on the actual working environment, including the relative positions of the components inside the A350 wheel. Therefore, the numerical range is relatively fixed and can be adjusted within ±10°. Figure 1 The first included angle α shown is 145°, so its adjustable range is 135° to 155°; Figure 1 The second included angle β shown is 110°, so its adjustable range is 100° to 120°.

[0043] The working principle of the aforementioned fixing tool is as follows:

[0044] When installing the main tire pressure sensor on an A350 aircraft, the operator first positions the fixing tool around the sensor base using the gripping part (i.e., the first plate-shaped element 1). The fixing body 3, thanks to its precise design and manufacturing, fits tightly against the base surface, forming a stable support structure. The operator then tightens the tire pressure sensor until the desired fixation is achieved. Throughout the process, the connecting part (i.e., the second plate-shaped element 2) ensures a secure connection between the fixing body 3 and the gripping part, preventing loosening or detachment due to external forces. Finally, once the tire pressure sensor is firmly fixed to the base, the operator can easily remove the fixing tool from around the base, completing the installation process.

[0045] Optionally, such as Figure 1 He Ru Figure 2 As shown, the fixing body 3 is fixedly connected to the second plate-shaped element 2 via the first bent portion 41. The first plate-shaped element 1 is fixedly connected to the second plate-shaped element 2 via the second bent portion 42, the bending direction of the second bent portion 42 being opposite to that of the first bent portion 41. The bent portion serves as a transition between the parts, making the connection point smoother and improving the safety when using the fixing tool.

[0046] Optionally, the tail of the first plate-shaped element 1 is provided with an opening. The opening facilitates hanging and storage when storing and fixing tools, saving space and making them easy to access.

[0047] Optionally, the surface of the first plate-shaped element 1 is provided with an anti-slip layer. The anti-slip layer increases the friction between the hand and the first plate-shaped element 1 when gripping, further improving the safety and efficiency of installation.

[0048] In summary, the precision fixing tool provided by this invention, through its unique design and high-precision manufacturing process, effectively solves the problem of easy loosening of the main tire pressure sensor base on the A350 aircraft during installation, improving installation accuracy and reliability, and providing strong protection for aviation safety. This fixing tool for the main tire pressure sensor base on the A350 aircraft has multiple advantages, including precise design, superior anti-loosening and anti-leakage performance, simple operation, high durability, convenient maintenance, and improved installation quality.
