Abstract
The utility model relates to a sealed indentation bolt belongs to fastening member technical field. Constitute by gasket and nut, the gasket be a bowl type structure, its towards one side of nut for the osculum end, the other end of keeping away from the nut is then for the macrostoma end, then for circular arc transition, the formation bowl type structure that macrostoma end, osculum are held and the circular arc passes through between macrostoma end and the osculum end. Will the utility model discloses be applied to occasions such as automobile tire, have tautness height, security advantage such as good.
Description
Technical field
This utility model relates to a kind of sealing indentation bolt, belongs to fastening member technical field.
Background technology
Bolt is extensive in applications such as building, constructions, but, for the applicable situations such as automobile tire, owing to the self structure such as automobile tire are limited, layout structure it is usually between its outer wall and inwall, if using conventional pad to coordinate with bolt to install, the problems such as poorly sealed the most easily occurring, affects the properly functioning of automobile.
Based on this, make the application.
Utility model content
Assembling the drawbacks described above in the presence of fastener cycle in order to overcome the parts such as existing automobile tire, this utility model provides that a kind of fastening effect is good, easy to operate, the sealing indentation bolt of good seal.
For achieving the above object, the technical scheme that this utility model is taked is as follows:
Sealing indentation bolt, be made up of pad and nut, described pad is bowl-type structure, it is osculum end towards the one side of nut, the other end away from nut is then big opening end, is then arc transition between big opening end and osculum end, and big opening end, osculum end and arc transition form bowl-type structure.
Further, as preferably:
Described nut includes that screw and nut body, screw are arranged with pad concentric, and the osculum end of pad is sleeved on nut body.It is furthermore preferred that described nut body is provided with boss towards osculum end, outer wall of boss forms interference fit with osculum end internal diameter.
Described screw opening place horizontal plane is less than nut body roof place horizontal plane, and is connected by arcuate structure between screw with nut body.
Sealing indentation bolt provided herein is in use, pad can be placed in automobile tire, and make osculum end outwardly, then after the boss of nut being loaded in osculum end, other associated components is carried out threaded by the thread groove in nut, i.e. assembles complete.
During use, owing to pad uses bowl-type structure, this structure outer wall is natural smooth arc structure, when pressure reduction occurs in tire, this pressure reduction can be oppressed on pad inwall through big opening end, and this does when firmly continuing outwards to press, and outer wall will directly block installation position, this active force is converted into seal pressure, thus improves sealing effectiveness；On the one hand arranging of boss further enhance sealing effectiveness, on the other hand, also functions to the effect of transition, and pad and nut are diverse two assemblies of internal diameter, are i.e. completed the transition of various outer diameter by the bolt of the application.

Detailed description of the invention
Embodiment 1
The present embodiment seals indentation bolt, in conjunction with Fig. 1, Fig. 2, it is made up of pad 1 and nut 2, in conjunction with Fig. 3 and Fig. 4, pad 1 is bowl-type structure, and it is osculum end 11 towards the one side of nut 2, and the other end away from nut 2 is then big opening end 12, being then arc transition 13 between big opening end 12 and osculum end 11, big opening end 12, osculum end 11 and arc transition 13 form bowl-type structure；In conjunction with Fig. 5 and Fig. 6, nut 2 includes that screw 21 and nut body 22, screw 21 are arranged with pad 1 concentric, and the osculum end 11 of pad 1 is sleeved on nut body 22.
Sealing indentation bolt provided herein is in use, pad 1 can be placed in automobile tire, and make osculum end 11 outwardly, then after nut 2 is coordinated installation with osculum end 11, other associated components is carried out threaded by the thread groove 21 in nut 2, i.e. assembles complete.
During use, owing to pad 1 uses bowl-type structure, this structure outer wall is natural smooth arc structure, when pressure reduction occurs in tire, this pressure reduction can be oppressed on pad inwall through big opening end 12, and this does when firmly continuing outwards to press, and outer wall will directly block installation position, this active force is converted into seal pressure, thus improves sealing effectiveness.
Embodiment 2
The present embodiment is identical with the setting of embodiment 1 and operation principle, and difference is: nut body 22 is provided with boss 221 towards osculum end 11, and boss 221 outer wall forms interference fit with osculum end 11 internal diameter；On the one hand arranging of boss 221 further enhance sealing effectiveness, on the other hand, also functions to the effect of transition, and pad 1 and nut 2 are diverse two assemblies of internal diameter, are i.e. completed the transition of various outer diameter by the bolt of the application.
Embodiment 3
The present embodiment is identical with the setting of embodiment 1 and operation principle, and difference is: screw 21 opening place horizontal plane is less than nut body 22 roof place horizontal plane, and is connected by arcuate structure 23 between screw 21 with nut body 22.
Claims (5)
1. seal indentation bolt, it is characterized in that: be made up of pad and nut, described pad is bowl-type structure, it is osculum end towards the one side of nut, the other end away from nut is then big opening end, being then arc transition between big opening end and osculum end, big opening end, osculum end and arc transition form bowl-type structure.
2. sealing indentation bolt as claimed in claim 1, it is characterised in that: described nut includes that screw and nut body, screw are arranged with pad concentric, and the osculum end of pad is sleeved on nut body.
