Description

Antiskid outer hexagonal bolt with medium

Technical Field

The utility model relates to a hexagon is taken and is situated between bolt technical field specifically is an antiskid outer hexagon is taken and is situated between bolt.

Background

The hexagon bolt is a fastener consisting of a head and a screw, and the bolt is divided into an iron bolt and a stainless steel bolt according to materials, namely, a hexagon bolt (partial threads) -C grade and a hexagon bolt (full threads) -C grade.

The hexagon bolt is used for fastening parts. The gasket matched with the existing hexagon bolt is placed between the nut and the screw head, and the gasket is not fixed and has poor fixing effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bolt is situated between to outer hexagonal area of antiskid possesses spacing fixed to the gasket, makes the fixed advantage of gasket, has solved the supporting gasket of hexagon bolt and has placed between nut and spiral shell head, and the gasket is unfixed, fixed not good problem of effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a bolt is situated between to outer hexagonal area of antiskid, includes screw rod and spiral shell head, be fixed with the screw rod in the middle of the spiral shell head lower surface, the nut is installed to the screw rod upper thread, the circular groove has been seted up in the spiral shell head lower surface outside, the embedded ring pad of installing in the circular groove, the ring pad is located between nut upper surface and the spiral shell head lower surface.

Preferably, the surface of the screw rod, which is different from the upper end and the lower end, is provided with a thread groove, and the thread groove is matched with the nut.

Preferably, the circular groove is matched with the circular pad, and the lower surface of the circular pad is lower than the lower surface of the screw head.

Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model discloses a set up ring groove and ring pad, reached spacing fixed to the gasket, made the fixed effect of gasket, the utility model discloses be provided with ring groove and ring pad, seted up the ring groove in the spiral shell head lower surface outside, be fixed with the screw rod in the middle of the spiral shell head lower surface, when installation ring pad and nut, with the ring pad embedding in the ring groove, ring pad and ring groove phase-match, screw up the nut, the nut supports the ring pad, fixes the ring pad between nut and spiral shell head, and the ring pad is more firm at the ring inslot.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to fig. 3, the present invention provides an embodiment: the utility model provides a bolt is situated between in hexagonal area outside antiskid, includes screw rod 1 and spiral shell head 4, is fixed with screw rod 1 in the middle of the 4 lower surfaces of spiral shell head, and screw rod 1 is different from the surface at upper and lower both ends and has seted up thread groove 2, and nut 5 is installed to the screw thread on screw rod 1, thread groove 2 and nut 5 phase-match. The ring groove 6 has been seted up in the screw head 4 lower surface outside, and ring pad 3 is installed to the embedded ring of ring groove 6, and ring groove 6 and ring pad 3 phase-match, 3 lower surfaces of ring pad are less than screw head 4 lower surfaces. When installation ring pad 3 and nut 5, fill up 3 imbeds with the ring and fill up in circular ring groove 6, screw up nut 5, nut 5 supports ring pad 3, and ring pad 3 is located between 5 upper surfaces of nut and the 4 lower surfaces of spiral shell head, and ring pad 3 is more firm in circular ring groove 6.

The working principle is as follows: when installation ring pad 3 and nut 5, fill up 3 imbeds with the ring and fill up in circular ring groove 6, screw up nut 5, nut 5 supports ring pad 3, and ring pad 3 is located between 5 upper surfaces of nut and the 4 lower surfaces of spiral shell head, and ring pad 3 is more firm in circular ring groove 6.
