Description

A kind of sealing screw

Technical field

The utility model relates to mechanical connecting element technical field, specifically a kind of sealing screw.

Background technique

Screw refers to screw, is the physics and mathematical principle for utilizing the inclined-plane circular rotating and frictional force of object, in proper order gradually Into the tool of ground fastening implements parts, screw is the general saying of fastener.Screw is a kind of common fastener, it is mechanical, It is widely used on electric appliance and building.General material is metal or plastic cement, and cylindrical, surface carves indent and convex ditch and is known as spiral shell Line.

Hydraulic, in lubricant industry, a kind of screw of demand has liquid to flow through in screw under certain pressure service condition Portion makes integrated hydraulic or lubrication product form access.But screw is in fixed product, due to the mobility characteristic of liquid, meeting Exist in the presence of the case where leakage, therefore designs a sealing screw.

Summary of the invention

The purpose of this utility model is to provide simple in order to provide a kind of not only structure, but also the hydraulic seal spiral shell of high reliablity Nail form, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides the following technical solutions:

A kind of sealing screw, including screw body, screw body neck junction are embedded with seal washer, the spiral shell The screw thread tail end for following closely ontology is equipped with spring steel ball structure.

As a further solution of the present invention: the seal washer is rubber washer.

Screw body neck junction is equipped with mutual with seal washer as a further solution of the present invention, The rolling type recess of cooperation.

Compared with prior art, the utility model has the beneficial effects that

A kind of sealing screw, structurally reasonable, novel in design, single structure is simple, low in cost, is not necessarily to special tool Tool, it is practical convenient for batch production.
