Description
Technical Field
The utility model relates to a screw application technology field, concretely relates to special bolt.
Background
Screw indicates the foreign language name of the screw: screen is a tool for fastening machine parts gradually by using the physics and mathematical principles of the inclined circular rotation and friction of an object. The mounting name of the screw is as follows: machine screws, self-tapping screws, drill screws, wallboard screws, fiberboard screws, wood screws, hexagonal wood screws, non-disengagement screws, combination screws, micro screws, furniture screws, electronic screws and chain belt screws. However, these screws are not suitable for use in certain situations, and therefore a special bolt is required to be designed for use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: provides a special bolt to overcome the defects in the prior art.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides a special bolt, includes head and axial region, the head sets up the left end at the axial region, the axial region middle-end is provided with bellied meson, the left side of axial region is middle polished rod portion, the right side of axial region is screw thread portion, the meson sets up the connection middle-end at middle polished rod portion and screw thread portion, screw thread portion right side still is connected with the bolt and inserts the end, the head with the junction is provided with connecting convex block between the axial region, the angle of inclination has been seted up to the connecting convex block tip that is close to the axial region, the head is including screwing up head and circular boss.
Furthermore, a mounting groove used for being matched with a screwdriver is formed in the tightening head.
Further, the diameter of the meson is larger than that of the threaded part.
Further, the diameter of the middle polished rod part is smaller than that of the threaded part.
Further, the head portion has a diameter larger than the shaft portion.
Further, the angle of the inclined angle is 45 °.
The utility model has the advantages that: the utility model puts the special bolt into the equipment or device to be fixed, the bolt is inserted into the end inserting hole, and then the bolt is screwed by the matching of the thread part until the meson props against the inner plate, and the circular boss of the head props against the outer plate and completes the installation; because a gap is reserved between the outer plate and the inner plate, thread installation is not needed, and therefore the middle polished rod part is arranged, the process flow is reduced, and the cost is reduced; the utility model adopts the cold plating process to directly form at one time, and has high production efficiency and low cost.

The tightening head 8 is internally provided with a mounting groove 10 for matching with a screwdriver.
The diameter of the meson 3 is larger than the thread part 5.
The diameter of the middle polished rod part 4 is smaller than the diameter of the threaded part 5.
The head portion 1 has a larger diameter than the shaft portion 2.
The angle of the inclined angle is 45 °.
The utility model discloses an installation principle: the utility model discloses a put into needs fixed equipment or device special bolt, insert in the 6 patchholes of end through the bolt, cooperate by screw thread portion 5 to screw again, screw until meson 3 supports inner panel 11, the circular boss 9 of head 1 supports planking 12 and accomplishes the installation; because a gap is reserved between the outer plate 12 and the inner plate 11, thread installation is not needed, and the middle polished rod part 4 is arranged, so that the process flow is reduced, and the cost is reduced; the utility model adopts the cold plating process to directly form at one time, and has high production efficiency and low cost.
The above examples are provided for further illustration of the present invention, but do not limit the present invention to these specific embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be understood as being within the protection scope of the present invention.
