Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aviation manufacturing and maintenance technology, and relates to a connection and fixing device. Background Technology
[0002] Aircraft maintenance involves the use of various materials and equipment. During material connections, secure fastening is crucial while ensuring ease of installation and disassembly. Angle clips are commonly used for fixing, but their assembly and disassembly are limited by angle and operating space, especially when the required angle is less than 90°. These limitations significantly increase the difficulty of assembling and disassembling angle clips (e.g., ...). Figure 1 , Figure 2 , Figure 3 As shown in the figure, it is necessary to design a connection and fixing device that can be used for splicing different materials to replace ordinary corner pieces and realize the convenience of material installation and disassembly. Utility Model Content
[0003] This utility model provides a connection and fixing device that improves the convenience of material assembly and disassembly while ensuring the strength and tightness of the material connection, thereby improving work efficiency.
[0004] The present invention adopts the following technical solution:
[0005] A connecting and fixing device includes connector A and connector B.
[0006] The connector A includes a fixed base A and a fastening part A, which are integral structures. The fixed base A is a plate-shaped structure with two mounting holes on its upper part for fixed connection with the material A to be connected. The fastening part A is fixed at the lower part of the fixed base A. The fastening part A is a hollow triangular prism shape, with two triangular faces on both sides and one of the three square faces fitting against the fixed base A. The lower edge of this face is flush with the lower edge of the fixed base A. The square face facing upward has screw holes A. The square face away from the fixed base A is missing for the connector B to be fitted into.
[0007] The connecting piece B has the same structure as the connecting piece A, and also includes a fixed base B and a fastening part B. The fastening part B also has a screw hole B, and the screw hole B has the same diameter as the screw hole A. The difference between the connecting piece B and the connecting piece A is that the fastening part B is smaller than the fastening part A, so that the fastening part B can be inserted into the inside of the fastening part A through the missing square face. After insertion, the outer surface of the fastening part B fits against the inner surface of the fastening part A, and the screw hole A and the screw hole B are coaxial. The two are fixed by fastening screws.
[0008] Furthermore, the triangular facets of the fastening parts A and B are isosceles triangles, with their apex angles located at the lower edges of the fixed bases A and B, respectively, i.e., at the junction of the fixed bases A and B. The angle of the apex angle is determined according to the angle required by the connected materials.
[0009] In use, first, fix the fixing base A to the material A to be connected through the two mounting holes. During fixing, the lower edge of the fixing base A should be flush with the edge of material A that will connect with material B. Then, fix the fixing base B to material B in the same way. Finally, insert the fastening part B into the fastening part A and secure them together with the fastening screws, thus completing the connection of the two materials. This connection method avoids the need for fixing the two sides of the angle bracket during installation, which requires both materials to be fixed at a pre-defined angle. This improves the efficient use of space during operation. The method of installing screws in screw holes A and B does not impose any space restrictions on the two materials.
[0010] The beneficial effects of this utility model are:
[0011] (1) This utility model adopts a docking structure, which is simple to operate and can fix the material in a relatively open space. Finally, the material docking process is simple and easy to operate.
[0012] (2) The processing and manufacturing method of this utility model is simple and can be made by casting. Attached Figure Description

[0026] The following description, in conjunction with the embodiments and accompanying drawings, further explains the specific implementation of this utility model, but is not intended to limit this utility model.
[0027] This embodiment provides a fixed connection device that improves the convenience of material assembly and disassembly while ensuring the strength and tightness of the material connection, thereby improving the work efficiency of material assembly and disassembly.
[0028] like Figure 4 and Figure 5 The connecting and fixing device shown includes connector A1 and connector B2.
[0029] like Figure 6 and Figure 7 The connector A1 includes a fixed base A3 and a fastening part A4, which are integral structures. The fixed base A3 is a plate-shaped structure with two mounting holes on its upper part for fixed connection with the material A to be connected. The fastening part A4 is fixed at the lower part of the fixed base A4. The fastening part A4 is a hollow triangular prism shape, with two triangular faces on both sides. One of the three square faces is in contact with the fixed base A3, and the lower edge of the square face is flush with the lower edge of the fixed base A3. The square face facing upward has screw holes A5. The square face away from the fixed base A3 is missing and is used for connector B2 to fit into. The two triangular faces are isosceles triangles, and their apex angles are located at the lower edges of the fixed base A3 and the fixed base B6, that is, at the junction of the fixed base A3 and the fixed base B6, with an angle of 90°.
[0030] like Figure 8 and Figure 9The connecting piece B2 has the same structure as the connecting piece A1, and also includes a fixed base B6 and a fastening part B7. The fastening part B7 also has a screw hole B8, and the screw hole B8 has the same diameter as the screw hole A5. The difference between the connecting piece B2 and the connecting piece A1 is that the fastening part B7 is smaller than the fastening part A4, so that the fastening part B7 can be inserted into the inside of the fastening part A4 through the missing square face. After insertion, the outer surface of the fastening part B7 fits against the inner surface of the fastening part A4, and the screw hole A5 and the screw hole B8 are coaxial. The two are fixed by the fastening screw 9.
[0031] In use, first fix the fixing base A3 to the material A that needs to be connected through the two mounting holes. When fixing, the lower edge of the fixing base A3 should be flush with the edge of material A that meets material B (e.g., Figure 10 Then, fix the base B6 to material B in the same way (e.g., Figure 11 Finally, insert the fastening part B7 into the fastening part A4 and secure them together with the fastening screw 9, thus completing the connection between the two materials (e.g., Figure 12 ).
[0032] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
