Technical Field

[0001] The utility model relates to the technical field of fasteners, and particularly relates to a hot-forged superalloy fastener. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely applied. On various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemical industries, instruments, and supplies, etc., various fasteners can be seen, and they are the most widely applied mechanical basic parts. Its characteristics are that there are a large variety of product specifications, different performance uses, and the degree of standardization, serialization, and generalization is also extremely high. Currently, the most commonly used fasteners in production are generally bolt and nut assemblies. Usually, in use, the bolt is first inserted into the screw hole, and then the nut is used in cooperation with the bolt head to clamp the fixed part in the middle, thereby playing a fixing role. However, since the nut is exposed to the environment, it is prone to loosening due to continuous impacts during use, and then the nut may become disengaged from the bolt, affecting the stability during fixation, and in severe cases, it may even cause production accidents. Therefore, a hot-forged superalloy fastener is proposed for the above problems. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the 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 of 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 belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1-3As shown in the figure, the present utility model provides a hot forging high-temperature alloy fastener, including a bolt member 1 and a nut member 2. The bolt member 1 is inserted into the nut member 2. A thin insert 3 is provided around the upper part of the bolt member 1. An annular slot 4 is opened in the upper part of the nut member 2, and the thin insert 3 is inserted into the annular slot 4.

[0022] The bolt member 1 is provided with a screw head portion 102 and a threaded rod portion 101, and a step is formed at the connection between the screw head portion 102 and the threaded rod portion 101.

[0023] Further, a plurality of thin inserts 3 are fixedly connected to the step surface at the connection between the screw head portion 102 and the threaded rod portion 101, and the plurality of thin inserts 3 are equally spaced on the step surface.

[0024] Further, there is a distance between the two side surfaces of the thin insert 3 and the side surfaces of the screw head portion 102 and the threaded rod portion 101 respectively.

[0025] A thin insert 3 is provided below the screw head portion 102 of the bolt member 1. The thin insert 3 will rotate when the bolt member 1 rotates. Since there are multiple thin inserts 3 and they are relatively thin, they will deform when contacting the nut member 2.

[0026] The nut member 2 is provided with an internal threaded hole portion 201.

[0027] Further, an annular slot 4 is opened in the upper part of the nut member 2, and there is a spacing between the annular slot 4 and the outside of the internal threaded hole portion 201.

[0028] The annular slot 4 provided above the nut member 2 will not affect the operation of the internal threaded hole portion 201.

[0029] The annular slot 4 corresponds to the lower parts of the plurality of thin inserts 3.

[0030] Further, the thin insert 3 is fixedly connected and inserted into the annular slot 4.

[0031] Wherein, after the thin insert 3 is inserted into the annular slot 4, the thin insert 3 will deform according to the shape in the annular slot 4.

[0032] Working principle:

[0033] A thin insert piece 3 is provided below the screw head portion 102 of the bolt member 1, and the thin insert piece 3 does not contact the side surface of the threaded rod portion 101, so it will not have an impact when the bolt member 1 rotates. A circular slot 4 is opened above the nut member 2 corresponding to the thin insert piece 3. When the bolt member 1 is screwed into the nut member 2, the thin insert piece 3 will gradually enter the circular slot 4. During the insertion process, the multiple thin insert pieces 3 will deform in a way of expanding outwards and deform according to the shape of the circular slot 4. Finally, the thin insert piece 3 is tightly attached to the inside of the circular slot 4 by means of insertion riveting. In this way, a large frictional force will be formed after the thin insert piece 3 is attached to the inside of the circular slot 4, so that the bolt member 1 hooks the nut member 2 when the thin insert piece 3 deforms, making the whole structure stable and not easy to fall off.
