Description

Technical Field

[0001] This utility model relates to the field of aviation equipment protection, specifically to a dust cap for aviation equipment parts. Background Technology

[0002] During operation, maintenance, and storage, aircraft components are highly susceptible to corrosion from dust, moisture, and other contaminants. These contaminants can cause surface corrosion and wear, ultimately affecting the performance and safety of the aircraft. Existing dust protection measures have several shortcomings for aircraft components. For example, some dustproof devices are too heavy, increasing the overall load on the aircraft; some have poor sealing performance and cannot effectively resist contaminants in harsh environments; and some are inconvenient to install and disassemble, hindering rapid maintenance of the aircraft. Therefore, developing a dust cap for aircraft components that meets the specific needs of aircraft is of great significance. Utility Model Content

[0003] The purpose of this utility model is to provide a dust cap for parts to solve the problems of large weight, poor sealing, and inconvenient installation and disassembly in existing dust protection measures for aviation equipment parts, so as to ensure the stable performance and safety of aviation equipment parts in various environments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust cap for a part, comprising: a hollow cylindrical body made of elastic rubber, the outer diameter of which is 5-10 mm larger than the maximum outer diameter of the adapted aviation bolt head, and a height 5-10 mm higher than the bolt head; a silicone rubber sealing gasket disposed in an annular groove on the inner wall of the end of the body that contacts the bolt, the gasket being 3-5 mm thick and having an inclination angle of 30°-45°; a polyurethane foam buffer pad located on the inner bottom surface of the body, the buffer pad being 2-3 mm thick; a raised toothed groove on the inner circular wall of the body, the toothed groove being wavy and made of the same material as the body; a hoop ring disposed on the outer circular wall at the end of the body, the hoop ring being 3-5 mm thick; reinforcing ribs evenly distributed along the outer surface of the body, the reinforcing ribs being 3-5 mm high and 2-3 mm wide, the reinforcing ribs, the hoop ring, and the body being integrally formed; and an air slit opened on the cylindrical end face of the body, the air slit communicating with the interior of the body. The outer surface of the main body is marked with the corresponding part number, specifications and applicable equipment location information, and the dust caps of different types of parts are distinguished by different colors.

[0005] It mainly consists of a hollow cylindrical body, a silicone rubber sealing gasket, and a polyurethane foam buffer pad. The body is made of elastic rubber. The outer diameter of the body is designed to be 5-10mm larger than the maximum outer diameter of the compatible aviation bolt head, completely covering the bolt head. Its height is 5-10mm higher than the bolt head, providing sufficient protective space. The silicone rubber sealing gasket is located in an annular groove on the inner wall of the body at the bolt contact end. The gasket is 3-5mm thick and utilizes the excellent elasticity and sealing properties of silicone rubber to tightly fit the bolt, effectively preventing dust and moisture from entering. The polyurethane foam buffer pad is located on the top inner surface of the body, corresponding to the top of the bolt head. It is 2-3mm thick and can buffer external impacts, protecting the bolt head from damage.

[0006] To facilitate rapid installation, raised grooves are designed into the inner wall of the cylindrical main body. The wavy structure of these grooves allows the main body to fit snugly onto the bolts. During installation, simply align the dust cap with the bolt and press down slightly. Air inside the main body will escape along the air gap, and the main body, along with the grooves, will deform and snap into the threads of the bolt, completing the installation. Simultaneously, the engagement of the grooves and threads prevents the dust cap from accidentally falling off or being lost.

[0007] For ease of maintenance, a clamp at the end of the main body allows for easy application of force by fingers. When the dust cap needs to be removed, simply pinch the main body and clamp together and pull slightly. Because the toothed groove is made of elastic rubber, it deforms, disengaging from the threads on the bolt. This releases the dust cap from the bolt, allowing for easy removal. Furthermore, to facilitate quick identification among numerous aerospace equipment parts, the corresponding part number, specifications, and applicable equipment location are marked on the outer surface of the main body. Different colors are used to distinguish dust caps for different types of parts, improving maintenance efficiency.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] Lightweight and high strength: The main body is made of elastic rubber, which reduces the overall weight of the aviation equipment while ensuring high-strength protection, meeting the strict requirements of the aviation industry for materials.

[0010] Excellent sealing performance: Silicone rubber gaskets can fit tightly with bolts, effectively blocking dust, moisture and other contaminants, ensuring that parts are not corroded in harsh environments.

[0011] Reliable cushioning protection: Polyurethane foam cushioning pads can buffer external impacts, prevent bolt heads from being damaged by impacts, and extend the service life of parts.

[0012] Easy installation and removal: The design of the toothed grooves and clamps makes the installation and removal of the dust cap simple and quick, improving the maintenance efficiency of aviation equipment.

[0013] Easy to identify: The labeling information and color-coded design make it easy for maintenance personnel to quickly and accurately identify parts, reducing maintenance errors. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution:

[0020] The installation process of a dust cap for a component: Align the dust cap with the aviation bolt, then press the main body 1 and the clamping ring 5 with slight force. The silicone rubber sealing gasket 2 and the toothed groove 4 deform and fit onto the bolt, completing the quick installation. Afterwards, the toothed groove 4 will engage with the threaded groove on the bolt to prevent the dust cap from falling off.

[0021] Disassembly process: When it is necessary to remove the dust cap for parts maintenance or inspection, pinch the protruding hoop 5 on the main body 1 with your fingers and pull it outward with a little force to deform the main body 1 together with the toothed groove 4 and the washer 2 and separate it from the bolt, so that the dust cap can be easily removed.

[0022] Identification and Maintenance: When performing equipment maintenance, personnel can quickly and accurately identify parts by checking the serial number, specifications, and applicable location information on the outer surface of the dust cap body 1. Furthermore, different colored dust caps further assist in distinguishing different types of parts, improving maintenance efficiency. During inspection, if the sealing gasket 2 or buffer pad 3 is found to be damaged, it can be replaced promptly to ensure the protective performance of the dust cap.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
