[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] The technical solution of this utility model is as follows: Figure 2 , 3 As shown, a plug-in type mounting and fixing structure includes: a pressure plate mounted on a power distribution device mounting frame and a plug fixed on the product base plate;

[0020] The tablet has a trapezoidal groove in the middle; both ends of the tablet are screwed to the mounting bracket of the power distribution device.

[0021] The front end of the insert is the insertion part, and the rear end is the connecting part; the insertion part has a trapezoidal structure, and the front end of the trapezoidal structure is narrow and thin, while the rear end is wide and thick, which is compatible with the trapezoidal groove; the connecting part is connected to the product base plate.

[0022] Insert the insert into the gap between the pressure plate and the mounting bracket to complete the installation and fixation.

[0023] The tablet compression and insertion plates are arranged symmetrically in pairs.

[0024] The connecting part has a stepped surface to fit the corresponding part of the equipment.

[0025] Tablets and inserts are manufactured by machining.

[0026] The insert is made of titanium alloy in one piece.

[0027] The purpose of this invention is to solve the problem of difficult disassembly and maintenance of aviation power distribution devices due to limited space between them, by utilizing a convenient installation mechanism. This can be achieved through the following technical solution:

[0028] First, pressure plates are installed on the mounting rack of the internal electrical distribution device of the aircraft. The installation distance of the pressure plates matches the installation position of the plugs on the electrical distribution device, which facilitates the positioning of the product on the aircraft mounting rack. The pressure plates do not need to be frequently disassembled, which can improve the maintainability of the product.

[0029] Secondly, the insert structure is fixed to the product base plate during product assembly. The insert is pushed into the gap between the pressure plate and the mounting bracket to fix the power distribution device.

[0030] Third, mounting brackets are designed on the other side of the power distribution device plug-in installation, and bolts are used to fix the mounting brackets to the mounting frame.

[0031] The aforementioned insert and compression structures can all be manufactured by machining.

[0032] The overall installation sequence is as follows:

[0033] 1) Install the pressure plate into the corresponding position on the aircraft mounting bracket using screws;

[0034] 2) Place the insert plate with one side aligned with the pressing position;

[0035] 3) Install the device onto the mounting plate component using screws.

[0036] The equipment plug-in mounting and fixing structure has three characteristics:

[0037] 1) The tableting structure allows for product disassembly without the need for disassembly;

[0038] 2) The insert structure eliminates the need for screws after being inserted under the pressure plate, reducing installation time;

[0039] 3) The insert has a trapezoidal structure, with a narrow and thin front end and a wide and thick rear end, which facilitates alignment and installation.

[0040] Figure 1 The diagram shows an aviation power distribution unit. Four mounting brackets are designed at the four corners of the unit. Bolts secure the unit to the aircraft mounting frame through through holes in the mounting brackets. Fixing and disassembling requires removing all four bolts. Furthermore, the bolts on the inward-facing side of the unit have limited operating space during installation, making tightening and disassembly inconvenient and resulting in poor maintainability.

[0041] The insert structure of the present invention is as follows Figure 2 As shown, the tablet compression structure is as follows Figure 3 As shown.

[0042] During installation, the operator holds the handle and pushes the power distribution unit into the mounting bracket, aligning the insert with the center of the pressure plate. After the insert and pressure plate are firmly fitted, secure it with bolts on one side of the mounting bracket. Tightening just two bolts is sufficient to fix the power distribution unit to the mounting bracket. Figure 4 As shown.

[0043] The above description is merely a specific embodiment of the present invention, providing a detailed description of the invention. Parts not covered herein are conventional techniques. However, the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
