Abstract
The utility model discloses a novel easily-detached double-head bolt, comprising a screw rod (1) and threads (2), wherein the threads (2) are arranged at two ends of the bolt; and a groove (3) is arranged at the top of one end of the bolt and a shallow slot (4) is arranged in the middle of the screw rod (1). With the adoption of the double-head bolt disclosed by the utility model, a common tool can be used as a tool for fastening or detaching a single head of the double-head bolt, so that the simple and convenient degree of detaching is greatly increased; when the double-head bolt is fastened, the damages to the threads are avoided when a back screw in the prior art is used, and the fastening degree of the bolt also can be guaranteed.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly a kind of novel stud bolt easy to assemble.
Background technique
Bolt refers in particular to the bigger screw of diameter, by head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous, needs to cooperate with nut, is used to be fastenedly connected two parts that have through hole.This Connecting format claims that bolt connects.As screwing off nut from bolt, can make these two parts separately again, be to belong to removably connect so bolt connects.Bolt can not have head yet, like stud bolt, claims stud yet.The most frequently used form of stud is that two ends have screw thread, and the centre is a polished rod.Most typical purposes: stone bolt, the perhaps place of foot bolt, thicker connection similarly, when can't realize with plain bolt.
Use the local a lot of of stud bolt in the reality, but when installing in order to protect screw thread, thereby very difficult assurance at first tightens the tightening degree of end.
Summary of the invention
Use this novel disclosed a kind of novel stud bolt easy to assemble, both can guarantee tightening degree, protected screw thread again to a great extent.Concrete technological scheme is:
A kind of novel stud bolt easy to assemble comprises screw rod 1 and screw thread 2, and the two ends of said bolt are equipped with screw thread.
One end top of said stud bolt has groove 3, and production method existing casting capable of using or stamping technology are cast or stamped out groove 3;
Described groove 3 is a yi word pattern, cross or star-like.
Screw rod 1 middle part of said stud bolt has shallow slot 4.
Instrument when the stud bolt of use the utility model can tighten instrument (like screw-driver, spanner) commonly used or dismantle as the stud bolt single head increases simple and easy, the comfort level of dismantling greatly;
When stud bolt tightens, can avoid tradition to use the injury of backrest screw double thread, can guarantee the tightening degree of bolt again.
Description of drawings
The commercially available normal stud bolt of Fig. 1.
Fig. 2, Fig. 3 are novel stud bolt easy to assemble.
Among Fig. 1, Fig. 2, Fig. 3,1 is screw rod, and 2 is screw thread, and 3 is groove, and 4 is shallow slot.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
A kind of novel stud bolt easy to assemble, as shown in Figure 2, comprise screw rod 1 and screw thread 2, the two ends of bolt are equipped with screw thread.One end top of bolt has groove 3, and production method existing casting capable of using or stamping technology are cast or stamped out groove 3; Groove 3 is a yi word pattern, cross or star-like.
At double thread screw one end when the retaining thread hole tightens, can be with the design's screw thread as in general sense screw, use screw-driver to act on groove 3 and bolt tightened to tapped hole for initial torsion.
A kind of novel stud bolt easy to assemble, as shown in Figure 3, comprise screw rod 1 and screw thread 2, the two ends of bolt are equipped with screw thread.Screw rod 1 middle part has shallow slot 4.
When the retaining thread hole tightens, can regard the design's stud bolt as in general sense single ended bolt at double thread screw one end, act on shallow slot 4 with spanner and bolt is tightened to tapped hole as initial torsion.
A kind of novel stud bolt easy to assemble comprises screw rod 1 and screw thread 2, and the two ends of bolt are equipped with screw thread.One end top of bolt has groove 3, and production method existing casting capable of using or stamping technology are cast or stamped out groove 3; Groove 3 is a yi word pattern, cross or star-like.Screw rod 1 middle part of bolt has shallow slot 4.
At double thread screw one end when the retaining thread hole tightens, can be with the design's screw thread as in general sense screw, use screw-driver to act on groove 3 and bolt tightened to tapped hole for initial torsion.
Perhaps, when the retaining thread hole tightens, can regard the design's stud bolt as in general sense single ended bolt, act on shallow slot 4 with spanner and bolt is tightened to tapped hole as initial torsion at double thread screw one end.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technological scheme of the utility model and model utility design thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
