Abstract
The utility model discloses a sealing type countersunk screw bolt, which comprises a bolt head and a screw stem, wherein an inside hexagonal groove is arranged on the upper end of the bolt head, a ring slot which surrounds the screw stem is arranged on the inclined wall of a lower end face of the bolt head, and a sealed rubber ring is embedded in the ring slot. The sealing type countersunk screw bolt has simple structure and reasonable design, by the design of the sealed rubber ring in the lower end face of the bolt head, the countersunk screw bolt after being mounted is enabled to have the sealing function, thus the countersunk screw bolt can be enabled to be applied to a machine with higher requirement on sealing performance, and the range of application of the countersunk screw bolt is enlarged.
Description
Technical field
The utility model relates to bolt field, is specially a kind of sealed type countersunk screw.
Background technique
Bolt is one of modal fastening piece, and it is made up of head and screw rod.It is cylindric that screw rod is, on have outside thread and can use with nut collocation.Screw bolt and nut uses jointly, can connect and fix two parts that have through hole.Bolt can be divided into hexagon head bolt, snap bolt, square spigot bolt, countersunk screw etc. by the head shape.And countersunk screw function ratio of the prior art is more single, does not possess the performance of sealing, therefore is not suitable in the higher machine of sealing requirements.
The model utility content
The purpose of this utility model provides a kind of sealed type countersunk screw, and is more single to solve countersunk screw function ratio traditional in the prior art, do not possess the performance of sealing, therefore is not suitable for the problem in the higher machine of sealing requirements.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sealed type countersunk screw includes bolt head and screw rod, it is characterized in that: described bolt head upper-end surface is provided with interior hexagonal groove, and the skew wall of described bolt head lower end surface is provided with the annular groove around screw rod, is embedded with sealing rubber ring in the described annular groove.
Described a kind of sealed type countersunk screw, it is characterized in that: described sealing rubber ring slightly protrudes from the skew wall of bolt head lower end surface.
The beneficial effects of the utility model are:
The utility model is simple in structure, reasonable in design, adopt the design that sealing rubber ring is set in the bolt head lower end surface, make to have sealing function after the countersunk screw installation, countersunk screw is applied to in the higher machine of sealing requirements, enlarged its using scope.
Description of drawings
Fig. 1 is sectional view of the present utility model.
