Description

Technical Field

[0001] The utility model relates to the technical field of aircraft assembly auxiliary tools, in particular to a device for disassembling Hi-Lok nuts. Background Art

[0002] For the fastener group of Hi-Lok nuts in the aircraft structure, during troubleshooting or modification, it is necessary to disassemble the installed Hi-Lok nuts. In the case of space limitations on the aircraft, the traditional Hi-Lok nut disassembly pliers need to be picked up and re-clamped and rotated multiple times. The Hi-Lok nut is damaged and stripped of its threads due to being clamped multiple times, resulting in the problem that the Hi-Lok nut cannot be unscrewed. Content of the Utility Model

[0003] To achieve the above object, the utility model provides a device for disassembling Hi-Lok nuts, including a hexagonal rod. One end of the hexagonal rod is provided with a sleeve. The inner circle of the sleeve is provided with left-handed taper threads. The sleeve is sleeved on the Hi-Lok nut. By rotating the hexagonal rod, the sleeve can be driven to rotate. The left-handed taper threads can bite the outer side surface of the Hi-Lok nut and drive the Hi-Lok nut to rotate relative to the Hi-Lok bolt.

[0004] In some possible embodiments, the sleeve and the hexagonal rod are integrally formed.

[0005] In some possible embodiments, the sleeve is made of a material with a hardness higher than that of the Hi-Lok nut.

[0006] In some possible embodiments, the sleeve is made of iron or iron alloy material.

[0007] In some possible embodiments, the outer side surface of the sleeve is frustum-shaped.

[0008] The beneficial effect of the utility model lies in that: the disassembly device of the utility model is provided with a sleeve at one end of the hexagonal rod, and left-handed taper threads are provided in the sleeve. During use, the sleeve is sleeved on the Hi-Lok nut, and a hexagonal wrench or a ratchet wrench is used to screw the sleeve through the hexagonal rod. The left-handed taper threads in the sleeve continuously bite the side surface of the Hi-Lok nut and drive the Hi-Lok nut to rotate, which can avoid stripping of the threads and remove the Hi-Lok nut. Moreover, the disassembly device of the utility model also has the advantages of simple structure, ingenious design and low manufacturing cost. Description of the Drawings

[0009] In order to more clearly illustrate the technical solutions in the embodiments of the utility model, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following drawings are only some embodiments of the utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0012] Reference numerals: hexagonal rod 1, sleeve 2, left-handed tapered thread 3. Detailed implementation manners

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Refer to Figure 1 And Figure 2 A high-lock nut disassembly device as shown, which includes a hexagonal rod 1 and a sleeve 2 provided at one end of the hexagonal rod 1. A left-handed tapered thread 3 is provided on the inner circle of the sleeve 2. During use, the sleeve 2 is sleeved on the high-lock nut, and a hexagonal wrench or a ratchet wrench is used to drive the sleeve 2 to rotate through the hexagonal rod 1. When rotating, the left-handed tapered thread 3 continuously bites the outer side of the high-lock nut, thereby avoiding slipping of the teeth and driving the high-lock nut to rotate relative to the high-lock bolt to remove the high-lock nut.

[0015] In some possible embodiments, the sleeve 2 and the hexagonal rod 1 are integrally formed, and it can be made of a material with a hardness higher than that of the high-lock nut, such as iron or ferroalloy. Specifically, after the basic shapes of the sleeve 2 and the hexagonal rod 1 are cast, the hexagonal rod 1 is then milled or turned, and finally left-handed tapered threads are tapped on the tapered inner circle of the sleeve 2.

[0016] In some possible embodiments, the outer side of the sleeve 2 is in the shape of a frustum of a cone, that is, the sleeve 2 is a conical cylinder with equal thickness, avoiding the problem of the sleeve 2 breaking due to stress concentration; and the conical cylinder structure can adapt to high-lock nuts of different sizes, with wide applicability and being easy to promote and popularize in various aircraft manufacturers.

[0017] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
