Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aviation ventilation windows, in particular to a window opening and closing auxiliary structure of an aviation ventilation window assembly. BACKGROUND

[0002] The aviation ventilation window is a key component on an airplane for adjusting cabin air pressure, balancing temperature and preventing fogging, generally designed in a circular or oval shape, capable of uniformly dispersing pressure and avoiding stress concentration, safer than early square cabin windows, and generally composed of three layers of glass, the outer layer being the strongest, the middle layer having air vents, and the inner layer mainly serving a protective purpose. The existing aviation ventilation window assembly is relatively laborious to operate and not easy to operate when opening and closing the window. SUMMARY

[0003] To solve the problems mentioned in the background, the present application provides a window opening and closing auxiliary structure of an aviation ventilation window assembly, which reduces the operating force when closing the window and facilitates window opening and closing.

[0004] The present application discloses the following technical solution: a window opening and closing auxiliary structure of an aviation ventilation window assembly, comprising a rocker arm, a bolt, a lock hook assembly, a self-locking nut one, a bolt, a spring support, a spring, and a self-locking nut two, the lock hook assembly is used to lock the ventilation window, the lock hook assembly is connected with the rocker arm through the bolt and the self-locking nut two, the rocker arm can rotate with the lock hook assembly to stretch the spring; the end of the rocker arm away from the lock hook assembly is provided with a spring support, the ventilation window is also provided with a spring support, the spring support is installed through the bolt and the self-locking nut one, the spring support can rotate on the bolt, the hooks at both ends of the spring are hung on the spring support, and the spring support can rotate in the hooks of the spring.

[0005] Further, the rocker arm is provided with a mounting hole matched with the lock hook assembly and the bolt.

[0006] Further, the spring support is in a cylindrical shape, the middle part of the spring support is provided with a mounting hole matched with the bolt, and the outer cylindrical surface of the spring support is provided with an arc-shaped groove matched with the hooks at both ends of the spring.

[0007] Further, the hooks at both ends of the spring are semicircular.

[0008] Compared with the prior art, the window opening and closing auxiliary structure of the present application has the following beneficial effects: 1. The adjustment of the force direction of the spring is realized through the rotation between the spring support and the spring hooks, the reduction of the operating force is realized through the spring rebound force, and the stretching and contraction of the spring are realized through the rotation of the rocker arm. 2. The window opening and closing auxiliary structure is fixed to the window frame by bolts. When the window is opened, the spring is in a stretched state. When the window is closed, the rocker arm rotates 150° with the locking hook assembly. The spring support rotates in the spring hook, so that the spring force is always in the direction of closing the window. The spring contraction generates a rebound force, reducing the operating force when closing the window and achieving the effect of saving effort. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of the present invention; Figure 2 This is a schematic diagram of the spring of the present invention; Figure 3 This is a schematic diagram of the rocker arm of the present invention; Figure 4 This is a schematic diagram of the spring support of the present invention; In the diagram: rocker arm 1, bolt 2, locking hook assembly 3, self-locking nut one 4, nut 5, spring support 6, spring 7, self-locking nut two 8. Detailed Implementation

[0010] like Figure 1 As shown in Figure 4, an auxiliary structure for opening and closing an aviation ventilation window assembly includes a rocker arm 1, a bolt 2, a locking hook assembly 3, a self-locking nut 4, a bolt 5, a spring support 6, a spring 7, and a second self-locking nut 8. The locking hook assembly 3 is used to lock the ventilation window. The locking hook assembly 3 is connected to the rocker arm 1 via the bolt 2 and the second self-locking nut 8. The rocker arm 1 can rotate 150° with the locking hook assembly 3 to stretch the spring 7. A spring support 6 is provided at the end of the rocker arm 1 away from the locking hook assembly. A spring support 6 is also provided on the ventilation window. The spring support 6 is connected by... Bolt 5 and self-locking nut 4 are installed. Spring support 6 can rotate on bolt 5. The hooks at both ends of spring 7 are hooked on spring support 6, and spring support 6 can rotate in the hooks of spring 7. The rocker arm 1 is provided with mounting holes that cooperate with locking hook assembly 3 and bolt 5. Spring support 6 is cylindrical. The middle of spring support 6 is provided with mounting holes that cooperate with bolt 5. The outer circular surface of spring support 6 is provided with arc-shaped grooves that cooperate with the hooks at both ends of spring 7. The hooks at both ends of spring 7 are semi-circular and cooperate stably with the arc-shaped grooves on the outer circular surface of spring support 6.

[0011] Working principle: The window opening and closing auxiliary structure is connected to the window frame by bolts. When the window is opened, the spring is in a stretched state. When the window is closed, the rocker arm rotates 150° with the locking hook assembly. The spring support is installed in the spring hook, so that the spring force is always in the direction of closing the window. The spring contraction generates a rebound force, reducing the operating force when closing the window.

[0012] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
