Description
Technical field
The utility model is related to a kind of from importing bolt.
Background technology
Bolt is industrial necessity indispensable in daily life, industrially also bears important task, common spiral shell
It is easy to scratch the screw thread of positioning screw when bolt uses, it is excessively high to lead to assemble remaining torsion, in assembly using process is screwed into advance, so
It is locked again with tool afterwards, it is time-consuming and laborious, therefore occur some in the market and import bolt, but import the guide thread tooth of bolt
Less than the externally threaded thread in positioning region, and the high all same of each tooth of guide thread tooth, it is screwed into time-consuming and laborious.
Utility model content
In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide a kind of anti-loosing effects
Good and time saving and energy saving imports bolt certainly.
The utility model adopts the following technical scheme that complete：It is a kind of to import bolt, including screw rod and head, spiral shell certainly
Bar includes guide part and positioning region, and the guide part includes chamfering guide part and fillet guide thread, the fillet guide thread
Between setting and chamfering guide part and positioning region, the circle book of the fillet guide thread encloses for 3-4, the fillet guide thread
The gradient is gradually increased to positioning region direction, and the positioning region includes external thread part and polished rod portion, and the polished rod portion is provided with several
Round bump.
The polished rod portion is set to the junction of positioning region and head.
The polished rod portion and the junction of screw rod are provided at least three sector elastic pressuring plate.
The one end of the sector elastic pressuring plate is fixed on the junction of bar portion and screw rod, the other end of fan-shaped elastic pressuring plate
Portion is free end.
The lower surface of the sector elastic pressuring plate is equipped with several fins.
The lower surface of the sector elastic pressuring plate is equipped with several fins.
Advantageous effect in the utility model：
1. from importing, bolt guide effect is good, and bolt is imported into threaded hole by chamfering guide part, round guide thread
The gradient is gradually increased as positioning region direction so that and the process that subsequent positioning region smoothly enters threaded hole is more time saving and energy saving,
More convenient is threaded into hole.
2. the polished rod portion of positioning region is provided with several round bumps, when the positioning region of entire bolt enters in threaded hole, light
The side wall for blocking threaded hole of the convex block of bar portion inflexibly, prevents it from exiting.
3. bolt is threaded into hole, flexible deformation is closely connect with attached article after fan-shaped elastic pressuring plate is pressurized, and is not necessarily to
In addition elastomeric pad is used, while the fin of fan-shaped elastic pressuring plate lower surface is caught in attached article, is brought into contact with even closer.
Description of the drawings
The utility model has following attached drawing：
Fig. 1 is the structural schematic diagram from importing bolt in utility model；
Fig. 2 is the present invention looks up structural representation from importing bolt in Fig. 1.
Specific implementation mode
Attached drawing illustrates the technical solution of the utility model and embodiment, is further described in fact in conjunction with attached drawing below
Apply each related details and its operation principle of example.
It is shown in reference picture 1, Fig. 2, it is provided by the utility model a kind of from importing bolt, including screw rod 1 and head 2, screw rod 1
Including guide part and positioning region 3, the guide part includes chamfering guide part 4 and fillet guide thread 5, the fillet guide thread
Between 5 settings and chamfering guide part 4 and positioning region 3, the circle book of the fillet guide thread 5 encloses for 3-4, and the fillet is oriented to spiral shell
The gradient of line 5 is gradually increased to positioning region direction, and the positioning region includes external thread part 6 and polished rod portion 7, and the polished rod portion 7 is set
Several round bumps 8 are equipped with, the polished rod portion 7 is set to the junction of positioning region and head, and bolt is imported by chamfering guide part 4
In threaded hole, the gradient of round guide thread 5 is gradually increased as positioning region direction so that subsequent positioning region 3 smoothly enters
The process of threaded hole is more time saving and energy saving, and more convenient is threaded into hole, and from importing, bolt guide effect is good, positioning region
Polished rod portion 7 is provided with several round bumps 8, and when the positioning region of entire bolt 3 enters in threaded hole, the convex block 8 in polished rod portion is inflexibly
The side wall for blocking threaded hole, prevent it from exiting, the junction of the polished rod portion 7 and screw rod is provided with the fan-shaped elasticity of at least three
Tabletting 10, the one end of the sector elastic pressuring plate 10 are fixed on the junction of bar portion and screw rod, fan-shaped elastic pressuring plate 10 it is another
One end is free end, and the lower surface of the sector elastic pressuring plate is equipped with several fins 11, and bolt is threaded into hole, fan-shaped bullet
Property tabletting be pressurized after flexible deformation closely connect with attached article, without in addition use elastomeric pad, while sector elastic pressuring plate
The fin 11 of lower surface is caught in attached article, is brought into contact with even closer.
