Abstract
The utility model provides a plug screw, comprising a hexagon head, a tool escape, a screw rod and the like, characterized in that a V shape tool escape is arranged between the screw rod and the hexagon head, wherein the tool escape is a taper body, having the advantage that the cone formed in the side where the V shape groove and the hexagon head joined together makes the airproof gasket regulating automatically thereby having a good airproof function when installing the airproof gasket.
Description
Technical field
The utility model relates to a kind of tapped through hole seal arrangement, especially can be used for sealing the plug screw of the tapped through hole on diesel engine oil, water, the feed channel.
Background technique
At present, its tool withdrawal groove of known plug screw is the rectangle annular groove.Usually be used with seal washer.Because the existence of rectangle tool withdrawal groove, the back seal washer is installed may secundly, makes the seal washer gland not live tapped hole, causes leaking.
Summary of the invention
Technical solution of the present utility model is such, and the utility model is that this plug screw can make the seal washer automatic centering, makes seal washer cover tapped hole all the time, prevents to leak.Comprise hexagon head, screw rod.The V-arrangement tool withdrawal groove is arranged between hexagon head and the screw rod, and tool withdrawal groove is a cone, when the tool withdrawal groove external diameter is equipped with seal washer, seal washer is aligned automatically, effectively covers tapped through hole.
The utility model advantage is a taper V-arrangement tool withdrawal groove external diameter when seal washer is installed, and cone can allow seal washer align automatically
Description of drawings
Structural assembly of the present utility model is such:
Fig. 1 is the plan view of the utility model plug screw;
Fig. 2 is the left view of the utility model plug screw;
Fig. 3 is that of the utility model plug screw implements to install sectional view.
Among Fig. 1～Fig. 3, hexagon head (1), tool withdrawal groove (2); Screw rod (3); Seal washer (4); Tapped through hole (5).
Embodiment
The most preferred embodiment that this practicality is implemented is such, mainly in conjunction with the accompanying drawings specific embodiment is described further below.With reference to Fig. 1～Fig. 3, do forming V-shape tool withdrawal groove (2) at screw rod to the plug screw tool withdrawal groove between the hexagon head, the footpath is more smaller than major diameter of thread V-arrangement tool withdrawal groove (2) combines the taper of a side with hexagon head (1) at the bottom of.After seal washer (4) is inserted in screw rod (3), contact with hexagon head (1) bottom surface, seal washer (4) endoporus is subjected to V-shaped groove (2) to combine the cone constraint of a side with hexagon head (1), automatically align tapped through hole (5), solved traditional rectangular tool withdrawal groove plug screw shown in Figure 4 when seal washer (4) is installed, because of seal washer (4) can't automatic centering tapped through hole (5), the usually problem of appearance leakage.
Claims (2)
1. a plug screw comprises hexagon head, screw rod, and it is characterized in that has V-arrangement tool withdrawal groove (2) between hexagon head (1) and the screw rod (3).
2. according to the described plug screw of claim 1, it is characterized in that tool withdrawal groove (2) is a taper.
