In order to achieve the above purpose, the utility model adopts the following technical scheme: a sealing screw fastener comprises a screw body and a sealing element, wherein the screw body consists of a head part, a screw rod part and a connecting rod part, the connecting rod part is fixedly connected between the head part and the screw rod part, the outer side surface of the connecting rod part is fixedly connected with a convex block, and the lower side surface of the head part is provided with an accommodating groove;
the sealing member comprises sealing washer and cover shell, sealing washer and cover shell are by rubber material integrated into one piece, the side of cover shell is provided with protruding shell, the quantity and the position homoenergetic of lug and protruding shell equal, and the outside of lug is located to protruding shell cover, the sealing washer is located the holding tank.
As a further description of the above technical solution:
the rotation center of the head part is superposed with the axes of the screw part and the connecting rod part.
As a further description of the above technical solution:
the outer diameter of the casing is consistent with the major diameter of the screw portion.
As a further description of the above technical solution:
the holding tank 0.3mm is stretched out to the downside of sealing washer.
As a further description of the above technical solution:
the shell is connected to the middle of the lower side face of the sealing ring.
As a further description of the above technical solution:
one side of the lug, which is far away from the connecting rod part, is in a cylindrical surface where the pitch diameter of the screw rod part is located.
The utility model discloses following beneficial effect has:
compared with the prior art, the sealing screw fastener can limit the rotation and the up-and-down movement of the sealing element formed by the sleeve shell and the sealing ring under the action of the connecting rod part surface lug, and the sealing element can elastically deform, so that the sealing effect can be better ensured after the sealing element is installed.
