Detailed Description
The utility model is further described with reference to the following figures and specific embodiments.
Referring to fig. 1, a through-wall type airtight socket 1 assembled on an aircraft, because of a high assembly density, a distance between two adjacent groups of airtight sockets 1 is very small (generally 3mm to 12 mm), and because the outer diameter of a compression nut 1-1 is large (between 27mm to 60 mm), the thickness is thin (about 3 mm), and the difference between the outer diameter of a shell boss 1-2 at the butt plug of the airtight socket 1 and the outer diameter of the compression nut 1-1 is small (about 10 mm), and the outer end surface of a hexagonal compression nut, which protrudes from the shell boss 1-2 of the butt plug of the airtight socket 1, is about 16mm to 22mm, so that a common open wrench or a socket cannot perform normal clamping operation at all; in addition, under the normal installation condition, the anti-loose metal fuse 1-3 arranged on the hexagonal compression nut 1-1 also limits the normal clamping position.
Referring to fig. 2, 3 and 4, the utility model provides a dismounting tool for a hexagonal gland nut of a through-wall airtight socket, wherein the dismounting tool for the hexagonal gland nut 2 is a cylindrical sleeve structure with one closed end; the outer diameter of the cylindrical sleeve is consistent with the outer diameter of a hexagonal gland nut 1-1 to be disassembled and assembled, the outer side face of the cylindrical sleeve is provided with a knurled texture 2-2, the closed end of the cylindrical sleeve is provided with a polygonal column type boss 2-1 protruding outwards (as a preferred embodiment of the utility model, the polygonal column type boss 2-1 is a hexagonal column boss), the inner cavity of the cylindrical sleeve is provided with a cylindrical hole 2-5 used for avoiding the boss 1-2 of a butt plug shell in the airtight socket 1, a hexagonal hole 2-4 matched with the outer side face of the hexagonal gland nut 1-1 on the airtight socket 1 is arranged at the position close to the open end of the inner cavity, the open end of the cylindrical sleeve is provided with a rectangular notch penetrating through the hexagonal hole and the outer side face of the cylindrical sleeve, and the rectangular notch is used for avoiding an anti-loosening metal fuse arranged on the hexagonal gland nut; the polygon prism-shaped boss 2-1, the hexagonal hole 2-4 and the cylindrical hole 2-5 are coaxially arranged.
Referring to fig. 2 to 5, when the hexagonal gland nut 1-1 in the airtight socket 1 in a narrow space is disassembled, firstly, the anti-loose metal fuse 1-3 in the safety hole of the hexagonal gland nut 1-1 is removed (the step is not required during assembly), then, the hexagonal gland nut disassembling tool 2 with the outer wall with the knurled texture 2-2 is held by hand and is placed at the front end of the airtight socket 1, so that the central axis of the hexagonal gland nut disassembling tool is basically consistent with the central axis of the airtight socket 1, then, the hexagonal gland nut disassembling tool moves towards the airtight socket 1 along the axis, and after the hexagonal gland nut 2-4 passes through the butt plug shell boss 1-2 part of the airtight socket 1, the hexagonal gland nut 1-1 of the airtight socket 1 is sleeved and clamped; and then the hexagonal gland nut dismounting tool 2 is rotated forwards or reversely, so that dismounting operation of the hexagonal gland nut 1-1 can be completed. In the operation process, when sealant is arranged at the fastening position of the wall-penetrating airtight socket 1 or the mounting thread of the airtight socket 1 is damaged or is buckled disorderly due to other reasons, the cylindrical knurled texture 2-2 of the hexagonal gland nut dismounting tool 2 is held by a hand to be dismounted, at the moment, the rotating torque can be increased in a mode of additionally adding a general open spanner or a double offset ring spanner, the general open spanner or the double offset ring spanner is firstly clamped or sleeved on the polygonal boss 2-1 of the hexagonal gland nut special tool 2, the hexagonal gland nut 1-1 can be screwed down by increasing the torque, and a small amount of lubricating oil can be coated on the mounting thread of the wall-penetrating airtight socket 1 to reduce the friction force if necessary, so that the dismounting of the airtight socket under special conditions can be completed.
The utility model is not only suitable for the disassembly and assembly of the wall-penetrating airtight socket in the narrow space, but also suitable for the tightness check of the wall-penetrating airtight socket hexagonal gland nut with the anti-loose metal fuse 1-3, when an inspector checks the tightness of the wall-penetrating airtight socket 1 which is installed through the hexagonal gland nut disassembling tool 2, the rectangular notch 2-3 at the opening end of the hexagonal gland nut disassembling tool 2 can be correspondingly clamped on the hexagonal gland nut 1-1 with the anti-loose metal fuse 1-3, and then the tightness check of the hexagonal gland nut 1-1 is carried out, because the anti-loose metal fuse 1-3 is not required to be disassembled, the defect that the anti-loose metal fuse 1-3 is required to be disassembled before the use of a general tool is overcome.
