Description

Technical Field

[0001] This utility model belongs to the field of mechanical limit structure design technology, and in particular relates to a quick connection and disassembly mechanism for compartments. Background Technology

[0002] Modules are crucial components of an aircraft's airframe structure. Currently, the main connection methods between modules include disc connections, socket connections, and wedge connections. Disc connections use axial bolts and nuts for fixing, but the space for assembly and disassembly is limited by the airframe, making operation inconvenient and disrupting the airframe's shape. Adding covers to maintain the shape further increases the workload of module docking and disassembly. Socket connections and wedge connections are suitable for connecting modules with regular shapes such as circular cross-sections, but their assembly and disassembly efficiency is low. Utility Model Content

[0003] Purpose of the utility model: In view of the above-mentioned existing technology, this utility model provides a quick connection and disassembly mechanism for compartments, which aims to improve the efficiency of assembly and disassembly between compartments and is also applicable to automated docking of compartments.

[0004] Technical Solution: To achieve the above-mentioned utility model objectives, a quick-connection and disassembly mechanism for compartments is designed, comprising a front compartment, positioning pin I, a locking hook module, positioning pin II, and a rear compartment. The locking hook module is installed on the inner end face of the front compartment via a bracket. Simultaneously, positioning pin I and positioning pin II are installed horizontally on the front compartment. The rear compartment is provided with a sloping boss, positioning hole I, and positioning hole II. When the front and rear compartments are docked, the two positioning pins first enter the positioning holes to ensure accurate positioning between the two compartments. After the end faces of the two compartments are fitted together, the screws on each locking hook module are tightened, and the locking hooks fit against the sloping boss on the rear compartment, achieving a secure connection between the two compartments.

[0005] Furthermore, the locking hook module includes a stop sleeve, a screw, a locking hook, a pin, and a rotating shaft. The middle part of the locking hook is connected to the bracket via the rotating shaft, and the front end of the locking hook engages with the inclined boss on the rear compartment. The rear end of the locking hook is threadedly connected to the bracket via a screw, and the stop sleeve is fixed by connecting and fixing it to the screw via a pin. The locking hook can be rotated up and down by rotating the screw.

[0006] Furthermore, the bracket is secured to the forward compartment with four bolts and nuts.

[0007] Furthermore, the front sections of locating pin I and locating pin II are provided with longer guide sections to facilitate the entry of the locating pins into the locating holes.

[0008] Furthermore, the number of locking hook modules can be designed according to the actual stiffness and load of the compartment.

[0009] Furthermore, there are eight locking hook modules, evenly arranged on the inner end face of the front compartment.

[0010] Technical advantages: This invention enables rapid connection and disassembly of compartments. The mechanism achieves a reliable connection between two compartments via locking hooks. Fastening bolts are arranged along the normal direction of the compartments, providing ample operating space. The modular design of the mechanism eliminates the need to remove screws during disassembly, facilitating quick assembly and disassembly. Attached Figure Description

Detailed Implementation

[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings or specific implementation examples. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described, and these examples should not be construed as limited to the examples set forth herein. Rather, these examples are described to better demonstrate the positive effects of this utility model, and all aspects not detailed herein are considered to be well-known or conventional techniques in the art.

[0017] See attached Figures 1-4 The mechanism consists of a front compartment 1, positioning pin I 2, a locking hook module 3, positioning pin II 4, and a rear compartment 5. The rear compartment 5 has a beveled boss 6, positioning hole I 7, and positioning hole II 8 on its end face. The locking hook module 3 consists of a stop sleeve 9, a bracket 10, a screw 11, a locking hook 12, a pin 13, and a rotating shaft 14. The locking hook 12 is connected to the bracket 10 via the rotating shaft 14, and the screw 11 is threadedly connected to the bracket 10. The stop sleeve 9 is fixed to the screw 11 via the pin 13. Rotating the screw 11 allows the locking hook 12 to rotate up and down. The locking hook module 3 is fixedly connected to the front compartment, positioned by its upper cylindrical boss, and secured by four sets of bolts and nuts. In this example, eight sets of locking hook modules 3 are used. When docking the front compartment 1 and the rear compartment 5, the positioning pins I2 and II4 on the front compartment 1 are inserted into the positioning holes I7 and II8 on the rear compartment 5 until the end faces of the two compartments are in contact, thus achieving positioning between the two compartments. Then, the screws 11 of each locking hook module 3 are tightened in sequence, and the locking hooks 12 press against the inclined boss 6 of the rear compartment 5, thus achieving a tight connection between the two compartments.

[0018] During installation, first assemble the lock hook module 3 using the stop sleeve 9, bracket 10, screw 11, lock hook 12, pin 13, and pivot 14. Then, install each lock hook module into the front compartment 1 in sequence. Loosen the screw 11 of the lock hook module 3, and the stop sleeve 9 will lift the lock hook 12 so that the head of the lock hook 12 is lower than the inner end face of the rear compartment 1, preventing interference when the two compartments are docked. Positioning pins I2 and II4 are installed onto the front compartment 1 with an interference fit. Finally, dock the front compartment 1 and the rear compartment 2. Keep the front compartment 1 fixed and move the rear compartment 5 along the hull axis until positioning pins I2 and II4 enter the positioning holes I7 and II8 on the rear compartment 5. Then, tighten the screws 11 of each lock hook module 3 in sequence to complete the docking of the two compartments.

[0019] The above specific embodiments or examples are only used to explain the technical solutions of this utility model and are not intended to limit this application. Parts not described in detail are considered to be conventional technical means or common knowledge in the field. It can be understood by those skilled in the art that, based on the design concept of this application, adaptive modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications, equivalent substitutions, and adaptive improvements do not depart from the technical essence of this utility model and should all be covered within the protection scope of this application.
