Embodiment 1

[0036] Such as Figure 1-4 As shown, the present invention provides a technical solution: a light universal aircraft canopy locking mechanism, including a canopy frame 1, a protective glass 2 and a canopy connecting plate 3, the canopy frame 1 is arranged on an arc surface, and the canopy frame The left side section of 1 is larger than the right side section of canopy frame 1. It adopts a streamlined design, which can make it more comfortable when using the canopy. The protective glass 2 is set on the surface of the canopy frame 1, and the bottom of the canopy frame 1 is set There are multiple groups of clamping blocks 5, and the clamping blocks 5 are connected with the connecting plate 3 of the canopy.

[0037] The clamping block 5 includes a connecting rod A501, an elastic triangular arrow rod 502 and an elastic member 503. The bottom of the connecting rod A501 is fixedly connected with the elastic triangular arrow rod 502. A501 is connected, and the bottom of the elastic t...

Embodiment 2

[0040] Such as Figure 1-4 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: the elastic member 503 can be a tension spring, and the elastic member 503 and the elastic triangular arrow rod 502 are perpendicular to each other, and the elastic effect of the elastic member is used to , can support the elastic triangular arrow rod 502, which is not easily damaged and ensures its safety.

Embodiment 3

[0042] Such as Figure 1-4 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the length of the section of the elastic triangular arrow rod 502 is greater than the groove length of the circular groove 6, so that the elastic triangular arrow rod after moving down 502 is deformed, and when it is in contact with the circular groove 6, a certain pressure is given, which can be easily stuck and locked, so that after it is completely locked, it is not easy to try to shake easily, and the safety of the aircraft is also guaranteed during flight.

[0043] The angle formed at the cross section of the elastic triangular arrow rod 502 is slightly larger than the angle formed at the bottom of the triangular groove 7, so that the elastic triangular arrow rod 502 after moving down is deformed, and a certain pressure is given while in contact with the triangular groove 3, It is easy to be stuck and locked at the same time, so that aft...

Abstract

The invention relates to the technical field of a cockpit cover accessories, in particular to a lightweight general aircraft cockpit cover locking mechanism. The lightweight general aircraft cockpit cover locking mechanism comprises a cockpit cover skeleton, protective glass and a cockpit cover connecting plate; the protective glass is arranged on the surface of the cockpit cover skeleton; multiple groups of clamping blocks are arranged at the bottom of the cockpit cover skeleton; and the clamping blocks are connected with the cockpit cover connecting plate. When an elastic triangular arrowhead rod moves downwards, the air below the elastic triangular arrowhead rod moves out of a one-way film; after the elastic triangular arrowhead rod is locked stably, the one-way film prevents the external gas from entering the one-way film and maintains stable, so that the elastic triangular arrowhead rod can be used stably after being locked; and compared with the single mechanical locking structure in the technology, the safety under the use state is guaranteed.

Description

technical field [0001] The invention relates to the technical field of canopy accessories, in particular to a locking mechanism for a light universal aircraft canopy. Background technique [0002] Light aircraft generally refers to aircraft with a maximum take-off weight of less than 5,700 kg. This kind of aircraft has the characteristics of lightness, safety, low requirements for use, ability to take off and land on grass, easy operation, and low price. Light aircraft are small and relatively simple, making them ideal for both leisure and business travel. Piston engines drive propellers, although some light aircraft have jet engines. Large, high-speed aircraft have landing gear that retracts the wheels after takeoff. In order to reduce weight and save costs, light aircraft are usually equipped with fixed legs. As new synthetic materials are developed, lightweight aircraft will become stronger, lighter and fly farther. [0003] The canopy is what the pilot or aircrew of...
