Abstract
The utility model relates to field of mechanical technique, specifically a kind of Anti-loosen sealing bolt of many grooves, comprise bolt body, the head supporting surface of bolt body is provided with at least one groove, outer ring groove is located at the head supporting surface of bolt body and is positioned at the outside of groove, the surface of groove is coated with gel coating, and described gel coating is locking glue or sealer coating.The utility model compared with the existing technology, on the head supporting surface of bolt, forge many grooves, apply locking glue or sealer on the surface of groove, after bolt is tightened, locking glue or sealer are driven plain and extend into the supporting surface of whole bolt, fill and lead up the micro-gap of supporting surface, thereby reached the effect of sealing; Under the frictional force effect of locking glue or sealer, make bolt can prevent that rotary type is loosening and non-rotating type is loosening; Many groove has left space more, thereby can prevent that locking glue or sealer from overflowing the head supporting surface of bolt after pressurized.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of Anti-loosen sealing bolt of many grooves.
Background technique
At present, existing bolt, after tightening, cannot reach the effect of sealing, and anti-loosing effect is also poor.When running into as expanded with heat and contract with cold, the reason such as vibration is while changing phase accessory thickness, existing bolt cannot prevent the bolt looseness causing thus.
Therefore, need to design one can either lockingly seal, and can prevent that again glue from overflowing the bolt of supporting surface.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one lockingly to seal, and can prevent that again glue from overflowing the bolt of supporting surface.
In order to achieve the above object, the utility model has designed a kind of Anti-loosen sealing bolt of many grooves, comprise bolt body, it is characterized in that: the head supporting surface of bolt body is provided with at least one groove, outer ring groove is located at the head supporting surface of bolt body and is positioned at the outside of groove, the surface of groove is coated with gel coating, and described gel coating is locking glue or sealer coating.
Described groove is annular, and width is 1mm, and the degree of depth is 0.5-1mm.
Described groove is 2-4 bar.
The thickness of described gel coating is 1-3mm.
Described locking glue or sealer are chemical glue or nylon glue.
Described locking glue or sealer, after being squeezed, extend into the supporting surface of whole bolt body.
The utility model compared with the existing technology, on the head supporting surface of bolt, forge many grooves, apply locking glue or sealer on the surface of groove, after bolt is tightened, locking glue or sealer are driven plain and extend into the supporting surface of whole bolt, fill and lead up the micro-gap of supporting surface, thereby reached the effect of sealing; Under the frictional force effect of locking glue or sealer, make bolt can prevent that rotary type is loosening and non-rotating type is loosening; Many groove has left space more, thereby can prevent that locking glue or sealer from overflowing the head supporting surface of bolt after pressurized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is bolt body; 2 is groove; 3 is gel coating; 4 is outer ring groove.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1 and Fig. 2, the utility model has designed a kind of Anti-loosen sealing bolt of many grooves, comprises bolt body.The head supporting surface of bolt body 1 is provided with the groove 2 of 2-4 bar, and outer ring groove 4 is located at the head supporting surface of bolt body 1 and is positioned at the outside of groove 2, and the surface of groove 2 is coated with gel coating 3, and gel coating is locking glue or sealer coating.
In the utility model, in order to play better locking and sealing effect, groove 2 is annular, and width is 1mm, and the degree of depth is 0.5-1mm.The thickness of gel coating 3 is 1-3mm.Locking glue or sealer are chemical glue or nylon glue.
Many groove 2 has left space more, thereby can prevent that locking glue or sealer from overflowing the head supporting surface of bolt body 1 after pressurized, groove 2 and preferred amount be 2-4 bar.
In use, after bolt body 1 is tightened, locking glue or sealer are being squeezed and are extending into the supporting surface of whole bolt body 1 the utility model, reach effect locking and sealing.
The utility model forges many grooves 2 on the head supporting surface of bolt body 1, apply locking glue or sealer on the surface of groove 2, after bolt body 1 is tightened, locking glue or sealer are driven plain and extend into the supporting surface of whole bolt body 1, fill and lead up the micro-gap of supporting surface, thereby reached the effect of sealing; Under the frictional force effect of locking glue or sealer, make bolt can prevent that rotary type is loosening and non-rotating type is loosening; Many groove 2 has left space more, thereby can prevent that locking glue or sealer from overflowing the head supporting surface of bolt body 1 after pressurized.
