Description

Technical Field

[0001] The present application belongs to the technical field of aircraft onboard equipment installation, and in particular relates to a bracket for rapid disassembly and assembly of aircraft onboard equipment. Background Art

[0002] Aircraft flight control, avionics, and electromechanical systems are becoming increasingly complex, resulting in a large number of onboard devices, which are widely distributed throughout the aircraft. Due to the varying shapes and mounting locations of each onboard device, the mounting brackets vary, necessitating a significant design and maintenance effort. Currently, common quick-release brackets often rely on onboard equipment racks for installation. However, large aircraft, with their numerous onboard devices and limited equipment racks, require direct installation of equipment that cannot be mounted on equipment racks. This necessitates the design of new brackets to accommodate the quick-release brackets in various installation environments, leading to significant coordination difficulties, time-consuming design, increased weight, and poor reliability.

[0003] Based on this, a bracket for quick disassembly and assembly of aircraft onboard equipment is designed, so that it can be directly installed on the aircraft structure without the need for a new auxiliary bracket, which has positive significance for aircraft design efficiency, weight reduction and security. Utility Model Content

[0004] The purpose of this application is to provide a bracket for rapid disassembly and assembly of aircraft onboard equipment, so as to solve the problem that existing onboard equipment needs to design new brackets in different installation environments, resulting in great coordination difficulties.

[0006] Preferably, the base is further provided with anti-slip ribs, and there are two groups of anti-slip ribs which are symmetrically arranged at one end of the base away from the guide rail ribs. The anti-slip ribs can be attached to the side wall of the chassis.

[0007] Preferably, the C-shaped angle piece, guide rail ribs, U-shaped angle piece and anti-slip ribs are integrally connected to the base.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] A bracket for quick disassembly and assembly of aircraft onboard equipment, such as Figure 1-Figure 3As shown, the chassis 8 is secured by a base 1 and horizontal guide rails 2. The base 1 is integrally provided with C-shaped angle pieces 3, guide rail ribs 4, U-shaped angle pieces 5, and anti-slip ribs 6. The base 1 is rectangular and internally provided with weight-reducing grooves. Four sets of C-shaped angle pieces 3 are symmetrically located on either side of the base 1. These C-shaped angle pieces 3 are internally provided with threaded holes for connection to the aircraft structure 7. There is ample space for the C-shaped angle pieces 3 to be installed, and either high-locking bolts or self-locking bolts can be selected based on the requirements of the aircraft structure 7.

[0017] There are two sets of guide rail ribs 4, symmetrically located at one end of the base 1. The guide rail ribs 4 are provided with threaded holes for assembly. There are two sets of anti-slip ribs 6, symmetrically located at the other end of the base 1. The horizontal guide rails 2 are L-shaped and provided with two sets. The two sets of horizontal guide rails 2 are connected to the two sets of guide rail ribs 4 respectively. Specifically, the bends of the horizontal guide rails 2 snap onto the guide rail ribs 4, and then connect to the guide rail ribs 4 with bolts or screws. When installing the chassis 8, the reserved grooves 9 on the chassis 8 shell are aligned with the horizontal guide rails 2 and pushed in to fix the chassis 8 in place. Two sets of anti-slip ribs 6 are provided on either side of the chassis 8 to limit the chassis 8 and prevent it from falling off the bracket.

[0018] There are two groups of U-shaped angle pieces 5 arranged at one end of the base 1 that is opened into the anti-slip vertical rib 6. The U-shaped angle pieces 5 are connected to the bent angle pieces 10 on the chassis 8 through bolts and nuts to fix the chassis 8 to the base 1.

[0019] In summary, the chassis 8 is securely fastened to the brackets by the base 1, guide rails, anti-slip ribs 6, and U-shaped angle pieces 5, ensuring multi-directional mounting of the chassis 8. This secures the chassis 8 to the brackets, ensuring multi-angle and multi-directional mounting of the chassis 8 to the aircraft structure 7 without requiring the design of new auxiliary brackets. This effectively reduces coordination and design difficulties and reduces aircraft weight. During bracket installation, the brackets can be secured to the panels, bulkheads, and beams of the aircraft structure 7 using the four C-shaped angle pieces 3. The connection method can be selected using either high-lock bolts or self-locking bolts, depending on the frequency of disassembly.

[0020] During installation, the chassis 8 can be placed on the base 1 of the bracket, and the chassis pull rod 11 can be pushed into the bracket so that the reserved groove 9 of the chassis 8 can be smoothly connected to the guide rail of the bracket. The angle piece 10 on the chassis 8 and the U-shaped angle piece 5 of the bracket can be connected with bolts and nuts to complete the installation and fixation of the chassis 8. Figure 4 When disassembling the chassis 8, unscrew the bolts and nuts connecting the angle pieces 10 on the chassis 8 and the U-shaped angle pieces 5 of the bracket, hold the chassis pull rod 11, and pull the chassis 8 out of the bracket to complete the disassembly of the chassis 8.

[0021] Finally, it should be noted that the drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.

[0022] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
