[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0045] Please see Figure 1-6 A prefabricated cabin insertion box structure includes a box body 1, which has an inlet and an outlet for wiring; it also includes:

[0046] The aviation plug mounting plate 2 is detachably fixed inside the housing 1 by at least one quick locking mechanism 3. The aviation plug mounting plate 2 is L-shaped and includes a vertical part 4 and a horizontal part 5. The vertical part 4 is provided with a plurality of mounting holes 6 for fixing the aviation plug, and the horizontal part 5 is provided with a cable management mechanism 7.

[0047] The quick-locking mechanism 3 enables the aviation plug mounting plate 2 to quickly switch between the locked position and the unlocked / disassembled position.

[0048] In this embodiment: First, the guide rail 27 at the bottom of the L-shaped aviation plug mounting plate 2, which integrates multiple aviation plugs, is aligned with the guide groove 26 inside the housing 1 and pushed in. At this time, the rotating handle 16 of the quick locking mechanism 3 is rotated, which drives the worm gear 15 to drive the worm wheel 14 and the bidirectional lead screw 9 to rotate, so that the two slides 10 move towards each other, causing the locking strip 12 to extend and lock into the locking groove 13 on the inner wall of the housing 1. The self-locking characteristics of the worm wheel 14 and worm gear 15 are used to firmly lock the mounting plate in the housing 1, so as to achieve quick installation. Next, the cables of each device are introduced from the inlet and outlet ports of the housing 1 and connected to the connectors on the vertical section 4. The cables are then placed sequentially into the V-grooves 22 of the cable management mechanism 7 on the horizontal section 5. The rotary knob 23 drives the bidirectional screw 19, causing the two cable clamps 21 with V-grooves 22 to move towards each other, adaptively clamping cables of different thicknesses. This state is then locked by the locking screw 24, thus completing the standardized fixing and sorting of the cables. Finally, the upper protective door 29 and the lower protective door 30 at the front of the sliding housing 1 have their arc-shaped grooves 31 on their side walls tightly fitted with the silicone pads 32 to form a seal. The upper protective door 29 and the lower protective door 30 are then locked by the rotating latch 33, providing comprehensive protection for the internal components.

[0049] As a technical optimization of this utility model, the quick locking mechanism 3 includes:

[0050] The mounting cavity 8 is formed along the length of the space within the interlayer of the aviation plug mounting plate 2;

[0051] The bidirectional lead screw 9 is rotatably mounted in the mounting cavity 8 via a deep groove ball bearing assembled on the outer wall;

[0052] Two slide blocks 10 are provided on the two sections of the thread of the bidirectional lead screw 9 and are slidably connected to the mounting cavity 8;

[0053] Two through slots 11 are provided on both sides of the aviation plug mounting plate 2 and communicate with the mounting cavity 8;

[0054] Two locking strips 12 are fixedly connected to two slides 10 respectively, and extend to the outside of the aviation plug mounting plate 2 through the through groove 11. The inner wall of the housing 1 is provided with a corresponding locking groove 13, and the locking strip 12 can be inserted into the locking groove 13.

[0055] The worm gear 14 is located at the center of the outer wall of the double-acting lead screw 9;

[0056] Worm 15 meshes with worm wheel 14;

[0057] The rotating handle 16 is located on the outer wall of the aviation plug mounting plate 2 and is coaxially fixedly connected to one end of the worm gear 15.

[0058] In this embodiment: through the linkage design of the bidirectional lead screw 9, slide 10, locking strip 12, worm gear 14, worm 15, and rotating handle 16, the operator only needs to rotate the rotating handle 16 to control the engagement or disengagement of the locking strip 12 with the locking groove 13 inside the housing 1, realizing the rapid switching of the aviation plug mounting plate between the locked and unlocked positions, improving the efficiency of disassembly and assembly, and avoiding the defects of complex operation and long time consumption of traditional fixing methods; there are two deep groove ball bearings, located on both sides of the worm gear 14; the worm gear 14 and the bidirectional lead screw 9 are fixed by a flat key connection.

[0059] As a technical optimization of this utility model, the cable management mechanism 7 includes:

[0060] Mounting base 17 is fixed to the horizontal part 5 of aviation plug mounting plate 2;

[0061] A groove 18 is formed on the mounting base 17;

[0062] The bidirectional screw 19 is rotatably disposed within the slide groove 18;

[0063] Two sliders 20 are mounted on the two threads of the bidirectional screw 19 and slide along the groove 18;

[0064] Two cable clamps 21 are fixed to the top of two sliders 20 respectively, and V-grooves 22 are provided on both sides of the two cable clamps 21.

[0065] Rotary knob 23 is coaxially and fixedly connected to one end of bidirectional screw 19.

[0066] In this embodiment: by rotating the rotary knob 23, the two cable clamps 21 are driven to move in opposite directions or in the opposite direction, adapting to and clamping and fixing aviation cables of different diameters, solving the problem of random cable distribution and difficulty in sorting out cables in the prior art, and ensuring neat wiring.

[0067] As a technical optimization of this utility model, a locking screw 24 is threaded along its axial direction on the side wall of the rotary knob 23. One end of the locking screw 24 can abut against the side wall of the mounting base 17 to lock the rotation state of the bidirectional screw 19.

[0068] In this embodiment: by using the locking screw 24, after the cable clamp 21 is adjusted to the appropriate position, the locking screw 24 can be turned to press against the mounting base 17 to lock the bidirectional screw 19, preventing the bidirectional screw 19 from loosening and the cable clamp 21 from shifting due to equipment vibration, and further improving the stability of cable fixing. A rubber pad is provided at the contact point of the locking screw 24.

[0069] As a technical optimization of this utility model, an elastic pad 25 is provided inside the V-groove 22.

[0070] In this embodiment: an elastic pad 25 is provided in the V-groove 22. On the one hand, it adapts to cables of different diameters through elastic deformation, thereby enhancing the clamping and sealing performance. On the other hand, it avoids direct contact between the cable and the rigid clamping seat, reducing wear on the cable sheath, and at the same time plays a role in buffering and vibration reduction, protecting the integrity of the cable.

[0071] The elastic pad 25 is made of silicone rubber with a Shore hardness of 50-60, which balances clamping force and cable protection.

[0072] As a technical optimization of this utility model, a guide groove 26 is provided at the bottom of the inner wall of the housing 1, and a guide rail 27 adapted to the guide groove 26 is provided at the bottom of the aviation plug mounting plate 2.

[0073] In this embodiment, the guide groove 26 and the guide rail 27 work together to provide guidance for the installation and removal of the mounting plate in the housing 1, ensuring that the mounting plate is accurately aligned and avoiding mismatch between the clip 12 and the slot 13 due to offset during installation, thereby improving the smoothness and accuracy of the installation and removal operations.

[0074] As a technical optimization of this utility model, the mounting base 17 is provided with a marking area 28 corresponding to each mounting hole 6.

[0075] In this embodiment, the marking area 28 on the mounting base 17 corresponding to each mounting hole 6 can be marked with information such as the corresponding equipment module and signal type of the aviation plug, which facilitates quick identification during maintenance and avoids misoperation.

[0076] As a technical optimization of this utility model, the front end face of the housing 1 is slidably provided with an upper protective door 29 and a lower protective door 30. The upper protective door 29 and the lower protective door 30 are provided with arc-shaped grooves 31 on opposite sides to the cable. The arc-shaped grooves 31 are provided with silicone pads 32. Rotary locks 33 are provided on both sides of the front end face of the upper protective door 29 and the lower protective door 30.

[0077] In this embodiment: the sliding upper protective door 29 and lower protective door 30 provide physical protection for the aviation plug inside the housing 1, preventing the aviation plug from being affected by bumps, dust, and humid air; the design of the arc groove 31 and silicone pad 32 not only accommodates the cable exit but also seals the gaps, further enhancing the protective effect; the rotating latch 33 can lock the protective door to prevent the protective door 30 from being opened accidentally when not in operation, ensuring the safety of the aviation plug.

[0078] Working principle and usage process of this utility model:

[0079] Fix the housing 1 to the designated position in the prefabricated compartment, ensuring that the inlet and outlet of the housing 1 face the same direction as the cable routing to avoid excessive cable bending; fix the aviation plugs one by one to the vertical part 4 of the aviation plug mounting plate 2 through the mounting holes 6, and mark the information (such as equipment module, signal type) in the marking area 28 of the mounting base 17 corresponding to the mounting hole 6 according to the aviation plug markings; insert the input / output cables of the aviation plugs into the inlet and outlet of the housing 1 respectively, pull the cables to the appropriate length (avoiding slack or tightness), turn the rotary knob 23 of the cable management mechanism 7 to drive the two cable clamps 21 to move towards each other, clamping the cables through the V-groove 22, and tighten the locking screw 24 to lock the bidirectional screw 19; align the guide rail 27 at the bottom of the aviation plug mounting plate with the guide groove 26 at the bottom of the inner wall of the housing 1, push the mounting plate to the designated position inside the housing 1, turn the rotary handle 16 of the quick locking mechanism 3 to drive the locking strip 12 to insert into the locking slot 13, and complete the process. Lock the mounting plate; slide the upper protective door 29 and lower protective door 30 on the front side of the box 1 so that the protective door completely covers the opening of the box 1, ensuring that the cable passes through the arc groove 31 without being squeezed, rotate the rotating latches 33 on both sides of the protective door to lock the protective door; turn on the power supply of the prefabricated cabin, test whether the equipment module connected to the aviation plug is working properly, check whether the cable clamp is firm, whether the protective door is sealed, and verify whether the information in the marking area 28 is accurate; if the aviation plug needs to be repaired or replaced, first disconnect the power supply, rotate the rotating latches 33 of the protective door in the opposite direction, and slide open the upper protective door 29 and lower protective door 30; rotate the rotating handle 16 of the quick locking mechanism 3 in the opposite direction to unlock the aviation plug mounting plate, and pull out the mounting plate along the guide rail 27; if the cable needs to be adjusted, loosen the locking screw 24, rotate the rotating knob 23 in the opposite direction to release the cable clamp seat 21, adjust and re-clamp and lock; after replacing the aviation plug, reassemble according to the above installation process, and then debug and check again.
