Detailed Description

The utility model is described in further detail below with reference to fig. 2-3.

The embodiment of the utility model discloses a non-standard pin with a neck and a flat tail of an inner hexagon. Referring to fig. 2, the inner hexagonal necked flat tail nonstandard pin comprises a screw head 31 and a stud 32, wherein the screw head 31 is fixed at one end of the stud 32, and a hexagonal hole 311 is formed at one end of the screw head 31, which is away from the stud 32. The end of the stud 32, which is far away from the screw head 31, is provided with a abutting head 321, and the end of the abutting head 321, which is far away from the stud 32, is provided with a limiting notch 322.

During installation, when fastening nonstandard round pin, the one end that supports tight head 321 and is equipped with spacing breach 322 can support tightly in second part 2, and then increases the resistance between double-screw bolt 32 and the second part 2, increases the restriction effect to double-screw bolt 32 reverse rotation for it is more firm when making the location to first part 1, increases nonstandard round pin's result of use.

Referring to fig. 2, a reinforcement portion 324 is disposed in the limiting gap 322, and the reinforcement portion 324 is integrally formed by the abutting head 321. The reinforcing portion 324 can reinforce the abutting head 321, increase the load bearing capacity of the abutting head 321 and increase the stability of the non-standard pin in use.

Referring to fig. 2, a guide portion 323 is formed at one end of the abutting head 321 near the stud 32, the guide portion 323 is in a frustum-shaped structure, the guide portion 323 and the stud 32 are coaxially arranged, the small end faces the abutting head 321, the large end faces the stud 32, and the diameter of the large end of the guide portion 323 is equal to the inner diameter of the nut 11.

In the process of penetrating the first component and the nut 11, the guide part 323 is abutted against the nut 11, so that the nut 11 is positioned and guided, the nut 11 can slowly deviate to the position coaxial with the stud 32, the nut 11 can be matched with the stud 32 conveniently, and the using effect is further improved.

Referring to fig. 2, the stud 32 includes a threaded portion 325 and an unthreaded neck 326, the neck 326 being secured to the threaded head 31, the threaded portion 325 being secured to the abutment head 321. Such that the provision of the neck 326 reduces the time for the thread making process while reducing the use of material.

To increase stability and load bearing capacity when tightening non-standard pins, hexagonal bore 311 extends to neck 326. When the hexagonal screwdriver is used for fastening the nonstandard pin, the stress part of the nonstandard pin can be closer to the middle part of the nonstandard pin, so that the stress of the nonstandard pin is more uniform, the stability of the nonstandard pin during installation is improved, and the use effect of the nonstandard pin is improved.

Referring to fig. 3, the bottom wall of the hexagonal hole 311 is provided with a cross hole 312, and the sidewall of the hexagonal hole 311 is provided with a straight hole 313.
