Abstract
The utility model relates to a seal structure of screw, including plug screw and seal ring, its characterized in that: the plug screw passes through seal ring and is connected with the screw, seal ring is the ring of red copper system, and the upper and lower both ends face of ring is bellied cambered surface to make ring hole and excircle department thickness be less than middle thickness. Above -mentioned technical scheme makes the big end face contaction of tradition become the facet line contact to utilized the more yielding characteristic of red copper material, when two fitting surface nonparallels of appearance are connected to plug screw and screw, through the effect of plug screw fastening power, have made sealed pad very easily form the sealing strip with the both ends face, thereby obtain better sealed effect.
Description
Technical field
This utility model belongs to technical field of sealing technology, particularly relates to the sealing structure of a kind of screw.
Background technology
At present, the mode typically all using plug screw and seal washer to combine is sealed for oil tank screw realize, described seal washer is the steel plain cushion that endoporus is bonded with rubber ring, owing to oilhole and plug screw are adding man-hour, certain error is the most all there is in its screw thread with the perpendicularity of end face, and the depth of parallelism of plain cushion both ends of the surface also has certain error, causing the sealing means of this structure oil leakage phenomenon easily occur, the most how producing preferable sealing effectiveness is the problem that we need solution badly.
Summary of the invention
This utility model is the sealing structure providing a kind of screw in order to solve the problems referred to above.
Scheme of the present utility model is achieved in that the sealing structure of a kind of screw, including plug screw and seal washer, it is characterized in that: plug screw is connected with screw by seal washer, described seal washer is the annulus that red copper is made, and the both ends of the surface up and down of annulus are the cambered surface of projection, and thickness at annulus endoporus and cylindrical is made to be less than interior thickness.
The beneficial effects of the utility model are: technique scheme, tradition large end face contact is made to become facet linear contact lay, and make use of the softer yielding characteristic of red copper material, plug screw be connected with screw appearance two cooperation faces not parallel time, effect by plug screw fastening force, make sealing gasket and both ends of the surface easily form band, thus obtain preferable sealing effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
In figure: 1, plug screw, 2, seal washer.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is further described:
The sealing structure of a kind of screw as shown in Figure 1, including plug screw 1 and seal washer 2, plug screw 1 is connected with unit screw, and between two connecting end surfaces, set seal washer 2, seal washer 2 is the annulus that red copper is made, and the both ends of the surface up and down of annulus are the cambered surface of projection, and thickness at annulus endoporus and cylindrical is made to be less than interior thickness 1mm.Owing to have employed said structure, tradition large end face contact is made to become facet linear contact lay, and make use of the softer yielding characteristic of red copper material, when plug screw be connected with screw both ends of the surface unparalleled phenomenon occurs time, effect by plug screw fastening force, easily make to be formed between packing ring and both ends of the surface band, thus obtain preferable sealing effectiveness.
