Description

Technical Field

[0001] The utility model relates to the technical field of aviation maintenance tools, in particular to a special socket wrench for disassembling and assembling a traction rod joint. Background Art

[0002] At present, due to the lack of suitable special wrench tools, the disassembly and assembly of aircraft tow rod joints has always relied on inserting a screwdriver into the slot on the tow rod joint and then using a hammer to complete the disassembly and assembly. Since there are four slots, the disassembly and assembly process is time-consuming and laborious, and it is also easy to cause additional damage to the aviation accessories. Utility Model Content

[0003] The purpose of the utility model is to address the above-mentioned deficiencies and provide a special socket wrench for disassembling and assembling a tow rod joint, which makes it easier to disassemble and assemble an aircraft tow rod joint, saves time and effort during the disassembly and assembly process, and avoids the situation where additional damage to other aviation accessories caused by disassembling and assembling the aircraft tow rod joint is caused.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A socket wrench specially used for disassembling and assembling a traction rod joint comprises a cylindrical main body, an outer prism-shaped joint is arranged at the top of the main body, four claws are arranged at the bottom of the main body, and an inner prism-shaped transfer interface is arranged inside the outer prism-shaped joint.

[0006] Furthermore, the main body is a hollow cylinder.

[0007] Furthermore, a plurality of straight slots are radially provided on the main body.

[0008] Furthermore, the outer prism-shaped joint is provided with six outer prism faces, and the six outer prism faces are arranged at equal angles with the axis of the main body as the center.

[0009] Furthermore, the inner prism-shaped transfer interface is provided with four inner prism surfaces, and the four inner prism surfaces are arranged at equal angles with the axis of the main body as the center.

[0010] Furthermore, each of the inner edges is provided with an elliptical avoidance groove.

[0011] The beneficial effects of the utility model are:

[0012] In actual applications, the four claws are respectively inserted into the corresponding grooves of the tow rod joint, an open-end wrench is used to clamp the outer prism joint or a ratchet wrench is used to insert the inner prism adapter, and the handle of the wrench is turned to load and unload the tow rod joint. The utility model makes it easier to disassemble and assemble the aircraft tow rod joint, and the disassembly and assembly process is more time-saving and labor-saving, and also avoids the situation where the disassembly and assembly of the aircraft tow rod joint causes additional damage to other aviation accessories.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a socket wrench specially used for disassembling and assembling a traction rod joint comprises a cylindrical main body 1, an outer prism-shaped joint 2 is arranged at the top of the main body 1, four claws 6 are arranged at the bottom of the main body 1, and an inner prism-shaped adapter 3 is arranged inside the outer prism-shaped joint 2.

[0020] In actual applications, the four claws 6 are respectively inserted into the corresponding traction rod joint slots, an open-end wrench is used to clamp the outer prism joint 2 or a ratchet wrench is used to insert the inner prism adapter 3, and the handle of the wrench is twisted to load and unload the traction rod joint. The utility model makes it easier to disassemble and assemble the aircraft traction rod joint, and the disassembly and assembly process is more time-saving and labor-saving, and also avoids the situation where the disassembly and assembly of the aircraft traction rod joint causes additional damage to other aviation accessories.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 1 is a hollow cylinder; in this embodiment, the hollow cylinder can reduce the weight and also play a role in supporting the overall strength of the tool.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a plurality of straight slots 5 are radially provided on the main body 1. In this embodiment, by radially providing a plurality of straight slots 5 on the main body 1, the weight of the tool can be further reduced, and the tool can be easily carried and used.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the external prismatic joint 2 is provided with six external edges, and the six external edges are arranged at equal angles with the axis of the main body 1 as the center; in this embodiment, the six external edges can make the external prismatic joint 2 compatible with common open-end wrenches.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner prism-shaped adapter 3 is provided with four inner prism faces, and the four inner prism faces are arranged at equal angles with the axis of the main body 1 as the center; in this embodiment, the inner prism-shaped adapter 3 can be adapted for use with common ratchet wrenches through the four inner prism faces.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an elliptical avoidance groove 4 is provided on each of the inner edges.

[0026] The specific examples described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific examples described or replace them in similar ways, but they will not deviate from the scope defined by the spirit of the present invention.
