Although this hex head bolt can play fixation, the sealability also had, seal ring has elasticity to nut when mounted, thus makes it have the trend got loose, and also will overcome power required when seal ring frictional force and elastic force are installed larger during installation.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of sealing bolt easy for installation.
For achieving the above object, the utility model provides following technological scheme: a kind of sealing bolt, be arranged in the tapped hole of deep gouge, comprise nut and screw rod, wherein: described nut be provided with the sealing station coordinated with deep gouge between screw rod, described sealing station side opening is provided with the seal groove for placing seal ring.
By adopting technique scheme, seal groove is arranged on the side of nut, thus when mounted, seal ring is conflicted with the side of deep gouge and is connected, relative to seal ring directly at bolt axial deformation, reduce resistance when bolt is installed, and the sidewall of seal ring and deep gouge is conflicted and is sealed, there is certain locating effect, ensure that the accurate installation of bolt.
The utility model is set to further: described nut is provided with rotation slot away from screw rod side, and the side of described rotation slot opening is provided with guiding chamfering, is provided with working station bottom described rotation slot.
The utility model is set to further: be provided with arc guiding face between described working station and rotation slot side.
The utility model is set to further, and described working station is set to the circle close with screw rod radius.
By adopting technique scheme, the use of the instrument that is set to of guiding chamfering provides locating function, thus instrument can easily be put into rotation slot, thus can installing/dismounting bolt more easily; The bolt that is set to of working station adds the position that provides conflict man-hour thus can process more easily, and working station is close with screw rod radius, thus to add clamping in man-hour more stable, arc guiding face the accurate clamping ensureing to add man-hour is set, easy to process.
The utility model is set to further: described nut is provided with angle of deflection towards the side of screw rod.
By adopt technique scheme, arranging of angle of deflection can guide nut accurately to install, make seal ring level and smooth enter connected piece, simple installation, the collision that it also avoid bolt and connected piece reduces to wear and tear.
The utility model is set to further: described nut is provided with bulge loop at seal groove towards the side of rotation slot.
By adopting technique scheme, can conflicting with the edge of seal ring of bulge loop, thus the installation of seal ring is more stable, prevents seal ring excessive deformation, affects using effect and working life.
The utility model is set to further: described screw rod comprises positioning section and thread section, is provided with location chamfering between described positioning section and thread section.
By adopting technique scheme, location chamfering arrange can screw accurately enter installation position, thus enhance installation capability, install easier.

Embodiment
The utility model is described in further detail for following respective figure.
A kind of sealing bolt, be arranged in the tapped hole of deep gouge, comprise nut 1 and screw rod 2, wherein: be provided with the sealing station 3 coordinated with deep gouge between nut 1 with screw rod 2, sealing station 3 side opening is provided with the seal groove 31 for placing seal ring; Nut 1 is provided with rotation slot 4 away from screw rod 2 side, and the side of rotation slot 4 opening is provided with guiding chamfering 41, is provided with working station 42 bottom rotation slot 4; Arc guiding face 43 is provided with between working station 42 and rotation slot 4 side; Working station 42 is set to the circle close with screw rod 2 radius; Nut 1 is provided with angle of deflection 32 towards the side of screw rod 2; Nut 1 is provided with bulge loop 11 at seal groove 31 towards the side of rotation slot 4; Screw rod 2 comprises positioning section 21 and thread section 22, is provided with location chamfering 23 between positioning section 21 and thread section 22.
Principle of the present utility model: seal groove 31 is arranged on the side of nut 1, thus when mounted, seal ring is conflicted with the side of deep gouge and is connected, relative to seal ring directly at bolt axial deformation, reduce resistance when bolt is installed, and the sidewall of seal ring and deep gouge is conflicted and sealed, and has certain locating effect, ensure that the accurate installation of bolt; The use of the instrument that is set to of guiding chamfering 41 provides locating function, thus instrument can easily be put into rotation slot 4, thus can installing/dismounting bolt more easily; The bolt that is set to of working station 42 adds the position that provides conflict man-hour thus can process more easily, and working station 42 is close with screw rod 2 radius, thus to add clamping in man-hour more stable, arc guiding face 43 the accurate clamping ensureing to add man-hour is set, easy to process; Arranging of angle of deflection 32 can guide nut 1 accurately to install, make seal ring level and smooth enter connected piece, simple installation, the collision that it also avoid bolt and connected piece reduces to wear and tear; Can conflicting with the edge of seal ring of bulge loop 11, thus the installation of seal ring is more stable, prevents seal ring excessive deformation, affects using effect and working life; Location chamfering 23 arrange can screw 2 accurately enter installation position, thus enhance installation capability, install easier.
