A non-standard bolt comprises a first cylinder, wherein the middle of the upper surface of the first cylinder protrudes outwards to form a second cylinder, the middle of the upper surface of the second cylinder protrudes inwards to form a first conical pit, and the diameter of the first cylinder is larger than that of the second cylinder; the lower surface of the first cylinder protrudes outwards to form a third cylinder, and the outer surface of the third cylinder is provided with an external thread; the lower surface of the third cylinder protrudes outwards to form a fourth cylinder, the outer surface of the fourth cylinder is recessed inwards to form four cambered surfaces which penetrate through the fourth cylinder along the axial direction, the four cambered surfaces are uniformly distributed and are symmetrical about the axis of the fourth cylinder, and the cross section of the fourth cylinder is symmetrical about the center; the lower surface of the fourth cylinder protrudes outwards to form a first cone.
Description
Technical Field
The utility model belongs to the technical field of the nonstandard bolt, specifically speaking relate to a nonstandard bolt.
Background
Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut to be used for fastening and connecting two parts with through holes, and the connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.
The bolt serving as a standard part can only realize the connection and fastening effect and cannot meet the matching requirements of some special connections, and particularly, some bolts not only need to be connected and fastened, but also need to play a limiting effect and a head connecting part, but the standard bolt cannot meet the requirements.
Disclosure of Invention
The utility model aims at providing a non-standard bolt, its head can the connecting element, can also play limiting displacement.
In order to solve the technical problem, the purpose of the utility model is to realize like this:
a non-standard bolt comprises a first cylinder, wherein the middle of the upper surface of the first cylinder protrudes outwards to form a second cylinder, the middle of the upper surface of the second cylinder protrudes inwards to form a first conical pit, and the diameter of the first cylinder is larger than that of the second cylinder; the lower surface of the first cylinder protrudes outwards to form a third cylinder, and the outer surface of the third cylinder is provided with an external thread; the lower surface of the third cylinder protrudes outwards to form a fourth cylinder, the outer surface of the fourth cylinder is recessed inwards to form four cambered surfaces which penetrate through the fourth cylinder along the axial direction, the four cambered surfaces are uniformly distributed and are symmetrical about the axis of the fourth cylinder, and the cross section of the fourth cylinder is symmetrical about the center; the lower surface of the fourth cylinder protrudes outwards to form a first cone.
On the basis of the above scheme and as a preferable scheme of the scheme: the second cylinder is fitted over the washer and riveted.
On the basis of the above scheme and as a preferable scheme of the scheme: the angle of the arc is 60 degrees.
Compared with the prior art, the utility model outstanding and profitable technological effect is:
the utility model discloses a nonstandard bolt, including first cylinder, second cylinder, third cylinder, fourth cylinder, through protrusion formation second cylinder on first cylinder, the riveting packing ring on the second cylinder makes the utility model discloses have the effect of connecting other parts, more practical than traditional standard bolt, the last indent of fourth cylinder forms four cambered surfaces, and four cambered surfaces play limiting displacement with the connecting piece, the utility model discloses not only have the effect of connecting the fastening, still played limiting displacement, application scope is wider.

Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like refer to the orientation or position relationship shown in the drawings, or the orientation or position relationship that the product of the present invention is usually placed when in use, or the orientation or position relationship that one skilled in the art conventionally understands, and are only for convenience of describing the present invention and simplifying the description, but do not refer to or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
The present invention will be further described with reference to the following detailed description;
the embodiment provides a non-standard bolt, which comprises a first cylinder 01, a second cylinder 02, a third cylinder 03 and a fourth cylinder 04, and the non-standard bolt of the utility model has an integrated structure, so that the overall strength is better;
the middle of the upper surface of the first cylinder protrudes outwards to form a second cylinder, the middle of the upper surface of the second cylinder protrudes inwards to form a first conical pit 020, the diameter of the first cylinder is larger than that of the second cylinder, a gasket 05 is sleeved on the second cylinder and riveted, so that the gasket is fixed on the second cylinder, and the first cylinder has a limiting effect on the gasket; sleeving a gasket on a second cylinder, then placing the product on a riveting machine for punching and riveting, and punching a first conical pit to enable the head of the second cylinder to expand outwards and clamp the gasket with the first cylinder; the gasket is embedded into the matched connecting piece, so that the reconnection operation of the utility model is reduced;
the lower surface of the first cylinder protrudes outwards to form a third cylinder, and the outer surface of the third cylinder is provided with external threads 030 which are used for connection and fastening; the lower surface of the third cylinder protrudes outwards to form a fourth cylinder, the outer surface of the fourth cylinder is recessed inwards to form four arc surfaces 040 which penetrate through the fourth cylinder along the axial direction, the four arc surfaces are uniformly distributed and are symmetrical about the axis of the fourth cylinder, and the cross section of the fourth cylinder is symmetrical about the center; the four cambered surfaces on the fourth cylinder are used for limiting, and the fourth cylinder is inserted into the bolt hole of the connecting piece to form limiting; the angle A of the arc is 60 degrees, and the best limiting effect is achieved.
The lower surface of the fourth cylinder protrudes outwards forming a first cone 06 which can be easily inserted into the connector.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
