Abstract
A stud with a torque applying structure comprises a stud body, and one scheme is that an outer convex tightening head which has a radial size smaller than the minor diameter of the thread of the stud and can be matched with a tightening tool is arranged at the end face of one end of the stud body, which is assembled with the torque applying structure. The other scheme is that a multi-surface tightening groove is arranged at the end face of one end of the screw cylinder for assembling and twisting. The utility model discloses the realization screwing up and the dismantlement of double-screw bolt that can be convenient, the adjusting torque of being convenient for moreover has improved assembly efficiency, and the cost is reduced has improved the security and the pleasing to the eye degree of product.
Description
Technical field
The utility model relates to a kind of threaded fastener technology field, particularly a kind of double-screw bolt of executing the kink structure that has.
Background technique
In the main accessory of mechanical connection and automobile was connected, the application of double-screw bolt was very extensive.When double-screw bolt connects in assembling, need elder generation that one end of double-screw bolt is screwed in the tapped hole of link.According to China Standard Press's in March, 2006 front page " fastening piece standard implementation guide ": an end of double-screw bolt utilize interference or other method to be screwed into and the firm endoporus that is fixed on workpiece substrate in, matrix is connected with nut through double-screw bolt.The place of turning round is not all executed on the double-screw bolt surface of present GB regulation, causes double-screw bolt when being screwed into tapped hole, can only directly twist spiro column and makes it get into tapped hole.Cooperate tighter occasion with tapped hole for double-screw bolt, these double-screw bolts can't directly be used tightening tool; Be screwed into the occasion that tapped hole moment has requirement for double-screw bolt, these double-screw bolts also can't directly be used and turn round the instrument assembling surely.Therefore just caused double-screw bolt assembling, the dismounting of present this form all very inconvenient, efficiency of assembling is very low.Cooperate tighter occasion with tapped hole for double-screw bolt, particularly double-screw bolt is screwed into the occasion that tapped hole moment has requirement, the double-screw bolt of present this form can only adopt other method to carry out indirect tightening and Torque Control; As adopt double nut to assist and tighten, double-screw bolt is executed the section of turning round and is screwed into two nuts now, tightens the nut of pre-installing on the double-screw bolt during assembling; Treat again double nut to be backed out from double-screw bolt after double-screw bolt is screwed into tapped hole; Such assembling is very loaded down with trivial details, and when double nut is back-outed, through regular meeting that double-screw bolt is loosening; Destroyed the screw-down torque of double-screw bolt, therefore influenced the control accuracy of double-screw bolt assembly quality with assembling moment.Therefore need a kind of double-screw bolt of executing the kink structure that has of development and Design, be convenient to the installation and removal of tightening of double-screw bolt, to improve the efficient of assembling, dismounting.
The model utility content
The utility model provides a kind of double-screw bolt of executing the kink structure that has, and this kind double-screw bolt can be realized tightening and dismantling of double-screw bolt easily, is convenient to regulate moment, has improved efficiency of assembling.
For realizing above-mentioned purpose, adopt following technological scheme:
A kind of double-screw bolt of executing the kink structure that has comprises spiro column, executes an end end of turning round in the assembling of said spiro column and is provided with and executes the kink structure, and said to execute the kink structure be a radial dimension less than double-screw bolt screw thread path, and the evagination tappet head that can cooperate with tightening tool; Said execute the kink structure be that a polygonal is tightened groove.
As the preferred version of the utility model, said evagination tappet head can be positive three prism, four-prism, positive hexagonal prism.
As another preferred version of the utility model, said polygonal is tightened groove can be regular polygon.
The utility model is executed the kink structure through executing in the spiro column assembling to turn round to hold to be provided with, and can realize tightening and dismantling of double-screw bolt easily, and be convenient to regulate moment, has improved efficiency of assembling, has reduced cost, has improved security of products and aesthetics.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model embodiment's overall structure figure;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the utility model embodiment's an application schematic representation.
Fig. 4 is the utility model another program embodiment's overall structure figure;
Fig. 5 is the left view of Fig. 4;
Fig. 6 is the application schematic representation of Fig. 4.
1, spiro column; 2, end face; 3, evagination tappet head; 4, tighten groove.
Embodiment
Shown in Fig. 1 to 6, provided the described a kind of embodiment who has the double-screw bolt of executing the kink structure of the utility model, among Fig. 1 to 6, be provided with orthohexagonal evagination tappet head 3 at 2 places, exterior edge face of spiro column 1, execute the kink structure as screwing up stud; Among Fig. 4 to 6, be provided with a regular hexagon at 2 places, spiro column 1 exterior edge face and tighten groove 4, execute the kink structure as screwing up stud.
Owing to be provided with at double-screw bolt 1 exterior edge face place and execute the kink structure, make double-screw bolt tighten assembling and dismounting is more simple and efficient, improved manufacturing efficiency, reduced cost.
Claims (3)
1. one kind has the double-screw bolt of executing the kink structure; Comprise spiro column; It is characterized in that, execute an end end of turning round in the assembling of said spiro column and be provided with and execute the kink structure that said to execute the kink structure be a radial dimension less than double-screw bolt screw thread path, and the evagination tappet head that can cooperate with tightening tool; Said execute the kink structure be that a polygonal is tightened groove.
2. a kind of double-screw bolt of executing the kink structure that has according to claim 1 is characterized in that, said evagination tappet head can be positive three prism, four-prism, positive hexagonal prism.
3. a kind of double-screw bolt of executing the kink structure that has according to claim 1 is characterized in that it is regular polygon that said polygonal is tightened groove.
