[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 Figures 1-3 This utility model discloses an aviation-grade toggle switch with good protective effect, comprising a toggle switch body 1, a lever 2 at the upper end of the toggle switch body 1, a detachable ring frame 4 at the upper end of the toggle switch body 1, a flexible protective sleeve 6 fixedly installed on the inner ring of the ring frame 4, a top ring 8 fixedly installed on the inner ring of the flexible protective sleeve 6, a bottom ring 7 at the lower end of the top ring 8, the bottom ring 7 and the top ring 8 being an integrated structure, both the bottom ring 7 and the top ring 8 being penetrated by the lever 2, and the inner wall of the bottom ring 7 being in contact with the lever 2, the inner ring of the top ring 8 being provided with a sealing ring 9 penetrated by the lever 2, and the sealing ring 9 being adhered to the inner ring of the top ring 8.

[0020] Both the flexible protective sleeve 6 and the sealing ring 9 are made of rubber.

[0021] Pre-assembly of protective components and lever 2:

[0022] First, fit the integrated top ring 8 and bottom ring 7 into the lever 2, so that the lever 2 passes through the bottom ring 7 and the top ring 8;

[0023] Since the inner ring of the top ring 8 is pre-bonded with a sealing ring 9, it is necessary to ensure that the sealing ring 9 is simultaneously penetrated by the lever 2 and tightly fitted with the inner ring of the top ring 8. At this time, the inner wall of the bottom ring 7 naturally fits against the outer wall of the lever 2, initially forming a sealing base around the lever 2.

[0024] Toggle block 3 is assembled and fixed:

[0025] The upper end of the lever 2 is provided with a detachable actuating block 3, and the top end of the lever 2 is inserted into the actuating block 3 and threadedly engaged with the actuating block 3.

[0026] Take the detachable toggle block 3, insert the top of the lever 2 into the toggle block 3, and rotate the toggle block 3 clockwise. By utilizing the threaded engagement between the two, the toggle block 3 is securely mounted on the upper end of the lever 2, thus completing the installation of the operating component at the top of the lever 2.

[0027] The ring frame 4 is assembled with the toggle switch body 1:

[0028] The bottom of the ring frame 4 is provided with a ring base plate 5, the upper end of the toggle switch body 1 is provided with a ring groove, the lower end of the ring base plate 5 is provided with a ring protrusion 10 inserted into the ring groove, the ring protrusion 10 is threadedly engaged with the toggle switch body 1, and the outer wall of the ring frame 4 is provided with anti-slip texture.

[0029] Hold the outer wall of the ring frame 4 (the outer wall has anti-slip texture for easy application of force), and move the ring base plate 5 at the bottom of the ring frame 4 synchronously with the ring frame 4. Align the ring protrusion 10 at the lower end of the ring base plate 5 with the ring groove at the upper end of the toggle switch body 1 and insert it.

[0030] Rotate the ring frame 4 clockwise. Through the threaded engagement of the annular protrusion 10 with the toggle switch body 1, the ring frame 4 is detachably fixed to the upper end of the toggle switch body 1. At this time, the flexible protective sleeve 6 fixed in the inner ring of the ring frame 4 completely covers the gap between the bottom of the lever 2 and the connection point of the toggle switch body 1, completing the overall assembly.

[0031] Switch usage and protection maintenance:

[0032] When in use, the lever 2 is moved to operate the switch. The bottom ring 7 moves slightly in sync with the lever 2 and always fits the lever 2. The flexible protective sleeve 6 can adapt to deformation without affecting the operation of the lever 2. At the same time, the sealing ring 9 continuously ensures the sealing between the top ring 8 and the lever 2, jointly preventing impurities from entering the interior of the ring frame 4.

[0033] The ring frame 4 is detachable through the threaded engagement between the ring protrusion 10 and the toggle switch body 1. The toggle block 3 is detachable through the threaded engagement with the lever 2. When the flexible protective sleeve 6 and the sealing ring 9 are aged or damaged, the ring frame 4 and the toggle block 3 can be easily disassembled for component replacement without replacing the entire switch, thus reducing maintenance costs and extending the overall service life of the switch.

[0034] The anti-slip texture on the outer wall of the ring frame 4 increases hand friction, making it less likely to slip when assembling or disassembling the ring frame 4, thus improving operating efficiency; the integrated design of the top ring 8 and the bottom ring 7 enhances structural strength and prevents parts from loosening; the flexible protective sleeve 6 and the sealing ring 9 are made of rubber, which not only has good deformation adaptability (does not hinder the shaking of the lever 2), but also resists oil stains and temperature changes in the aviation environment, ensuring long-lasting protection without affecting the switch operation performance.

[0035] Toggle lever 2 material: Polyoxymethylene (POM) or 6061-T6 aluminum alloy (surface anodized);

[0036] Based on: POM possesses high wear resistance and self-lubricating properties, making it less prone to jamming when tossed or wiggled, and also has good insulation properties, avoiding the risk of short circuits; the aluminum alloy material is lightweight (density only 2.7g / cm³). 3 After anodizing, the corrosion resistance is significantly improved, meeting the "weight reduction + corrosion resistance" requirements of aerospace equipment and making it suitable for weight-sensitive applications. Both materials can withstand fatigue wear from frequent manipulation, ensuring long-term stability.

[0037] 4. Circular frame, 5. Circular base plate, 10. Circular protrusion: Material: Polycarbonate (PC) or PPS;

[0038] Basis: The three components form an integrated structure (annular protrusion 10 is fixed to annular base plate 5, and annular base plate 5 is fixed to annular frame 4), requiring sufficient rigidity to support the flexible protective sleeve 6. PC has high impact resistance (notched impact strength ≥ 60kJ / m). 2 It is not easily broken by vibration; PPS has better temperature resistance and corrosion resistance, making it suitable for installation in high-temperature areas such as near engines. The anti-slip texture on the outer wall of the ring frame 4 can be integrally molded. Both materials are easy to process and have good insulation, avoiding circuit interference with other components.

[0039] Flexible protective sleeve 6 and sealing ring 9 are made of fluororubber (FKM) or silicone rubber (VMQ).

[0040] Basis: Both are commonly used sealing / protective rubbers in aviation applications. Fluororubber has a temperature resistance range of -20℃ to 200℃, extremely strong resistance to oil and hydraulic oil corrosion, and good deformation recovery, allowing it to adapt to deformation without cracking as the lever 2 is shaken. Silicone rubber has a wider temperature resistance range (-60℃ to 260℃), better elasticity, and is suitable for extreme low-temperature environments. Both materials can tightly fit the lever 2 and the top ring 8, forming a reliable seal and preventing the intrusion of dust and metal debris.

[0041] Top ring 8 and bottom ring 7 are made of PC or ABS with glass fiber reinforcement (ABS + 20% GF).

[0042] Based on the following: The top ring 8 and bottom ring 7 are an integrated structure, requiring the flexible protective sleeve 6 to be fixed and adhered to the lever 2. PC material has high strength and good insulation, and can be firmly connected to the flexible protective sleeve 6 through bonding; ABS+fiberglass is lower in cost and has a certain degree of rigidity, making it suitable for cost-sensitive mass production scenarios. Both materials are not prone to scratching the surface of the lever 2 and are resistant to vibration fatigue, preventing a decrease in the fit with the lever 2 after long-term use.
