Description

Technical Field

[0001] This application belongs to the field of airborne equipment mounting brackets, and specifically relates to an aircraft smoke detector mounting bracket. Background Technology

[0002] Smoke detectors are commonly used to detect smoke and play a crucial role in aircraft fire prevention systems as fire alarm and early warning devices. Smoke detectors are relatively lightweight and can usually be fixed to the top of the structure with screws. However, some aircraft structures do not provide suitable space for smoke detector installation, such as those with curved tops or numerous overhead devices. In such cases, a special bracket is needed to secure the smoke detector to the structural frame. Since the structure and shape of different cabin frames vary, it is difficult to use a single type of bracket to achieve the desired installation of smoke detectors.

[0003] Therefore, there is an urgent need for a technical solution to overcome or mitigate at least one of the aforementioned defects in the existing technology. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0025] This application provides an aircraft smoke detector mounting bracket, including: a bracket fixing plate 1, a smoke detector fixing plate 2, and a reinforcing plate 3.

[0026] like Figure 1 As shown, the bracket fixing plate 1 has bracket connection holes 4 for connecting the bracket to the airframe structure. The structural shape of the bracket fixing plate 1 can be designed according to the shape of the area where the airframe structure is installed to better adapt to the installation. The arrangement and number of bracket connection holes 4 on the bracket fixing plate 1 can be designed according to the shape of the frame of the airframe structure. In the preferred embodiment of this application, considering the weight reduction requirements of the aircraft design, the bracket fixing plate 1 has weight reduction holes 5.

[0027] The smoke detector mounting plate 2 is vertically connected to the bracket mounting plate 1. The smoke detector mounting plate 2 has smoke detector connection holes for connecting to smoke detectors. In a preferred embodiment of this application, considering the weight reduction requirements of aircraft design, the smoke detector mounting plate 2 has weight reduction holes 5. The smoke detector mounting plate 2 has multiple smoke detector mounting positions. The smoke detectors are directly connected to the smoke detector mounting plate 2 with screws. Depending on the smoke detection requirements, two or more smoke detectors can be installed side-by-side. In this embodiment, the connection between the smoke detector mounting plate 2 and the bracket mounting plate 1 is chamfered.

[0028] The reinforcing plate 3 is connected to both the bracket fixing plate 1 and the smoke detector fixing plate 2, and stress relief holes 6 are provided at the connection points of the reinforcing plate 3, the bracket fixing plate 1, and the smoke detector fixing plate 2. The reinforcing plate 3 strengthens the connection between the bracket fixing plate 1 and the smoke detector fixing plate 2, improving the rigidity of the bracket to withstand vibration and impact during operation. The stress relief holes 6 are located at the corners of the bracket structure to release concentrated loads on the bracket under stress, reducing stress concentration at those locations. In a preferred embodiment of this application, considering the weight reduction requirements of aircraft design, weight reduction holes 5 are provided on the reinforcing plate 3. In this embodiment, a chamfer is provided at the connection point between the reinforcing plate 3 and the smoke detector fixing plate 2.

[0029] This application designs an aircraft smoke detector mounting bracket as a versatile corner box structure. Firstly, the shape of the bracket's fixing plate 1 can be designed to adapt to different structural shapes, allowing the smoke detector installation to be unrestricted by the aircraft's structural shape. Secondly, the position and number of bracket connection holes 4 can be flexibly designed based on the size and shape of the fixing plate 1, ensuring effective connection between the bracket and the aircraft structure. Finally, depending on smoke detection requirements, two or even more smoke detectors can be installed simultaneously using this bracket, guaranteeing detection effectiveness. This bracket design adapts to different structural forms of installation compartments, employing a variable design that is highly efficient and easy to use.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
