Single, convenience.
Oil filler point in other screw head is set to cylindrical thread hole, can be formed with sealing screw and is connected.Oil filler point
Used cooperatively using cylindrical thread hole and sealing screw, sealing screw is easy to dismounting, plug solved in the lump and is easy to weathering change
The problem of matter.
The annular groove set with screw rod junction around screw head on the screw head downside of screw body, can place one
Individual sealing ring can make to be formed between screw head and workpiece or equipment when being screwed into workpiece or equipment in screw body together with it is flexible
Sealing, also has in traditional handicraft and installs sealing ring additional in the screw head position of screw body, but is all directly to add under conventional situation
A sealing ring is filled, is formed between one between the screw head and workpiece or equipment of screw body during screw body is tightened
Gap, and under long-term open-air conditions in the middle of pad sealing ring can produce it is aging so that screw body loosen so as to influence
Screw sealing in itself, in the case that situation continued deteriorates, by the sealing of further influence whole device equipment.But it is logical
Cross and annular groove is set in screw head downside, sealing ring can be placed into annular groove, because sealing ring has pliability in spiral shell
Nail tighten during its volume can be extruded under by whole pressed into groove, therefore between screw head and workpiece or equipment not
Can form gap, therefore the setting of annular groove can not only play preferable sealing effectiveness and not interfere with the tight of screw body also
Degree.The inside and outside side face of annular groove is set in the design slope make its formed with annular groove top face it is small under
Big trapezium structure annular groove, sealing ring is positioned over top face in annular groove and is tightly fitted with the top face of annular groove, sealing
Ring it is inside and outside while face and annular groove it is inside and outside while face form a triangular space, so as in sealing ring in the process being extruded
Middle sealing ring will not surmount annular groove and be compressed between screw head and workpiece or equipment makes shape between screw head and workpiece or equipment
Into gap, so as to ensure that the tightness that screw body is screwed into, and thoroughly solve sealing ring weathering and cause what screw body loosened
Problem.
