The utility model adopts the following technical scheme: a convex-concave gasket of a steam turbine comprises a convex buffering ring, a groove fixing piece, a threaded opening, a deformation groove, a fastening piece and an elastic buffering ring, wherein the convex buffering ring is arranged on the fastening piece, the groove fixing piece is arranged on the convex buffering ring, the threaded opening is arranged on the groove fixing piece, the deformation groove is arranged at the bottom end of the convex buffering ring, the elastic buffering ring is arranged at one end of the elastic buffering ring and is arranged at the bottom end of the fastening piece, the other end of the elastic buffering ring is arranged below the fastening piece and is not in contact with the fastening piece, the convex buffering ring is arranged between the fastening piece and the groove fixing piece, the groove fixing piece is arranged between the threaded opening and the convex buffering ring, the fastening piece is arranged between the convex buffering ring and the elastic buffering ring, the threaded opening is an inlet for fastening, the convex buffering ring buffers part of the fastening force, and the fastening piece connects parts, the elastic buffer ring buffers the resilience of the other part of the fastening.
Further, the threaded opening is arranged in a circular opening.
Further, the protruding buffer ring is arranged in a conical shape.
Furthermore, the groove fixing pieces are arranged in a circular ring shape.
Furthermore, the deformation groove is in the shape of a circular groove.
Furthermore, the section of the elastic buffer ring is trapezoidal.
Further, it is preferable that the convex buffering ring, the concave fixing piece, the fastening piece and the elastic buffering ring are made of 304 stainless steel.
Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the utility model provides a gasket combination with two kinds of different grade types realizes making the fixed purpose of fastener together, and the device has the higher characteristics of resilience than current gasket, and fundamentally has solved in the use fastener even use the elasticity gasket still to have not hard up problem.
Drawings
Fig. 1 is a schematic view of the overall structure of a convex-concave gasket of a steam turbine according to the present invention;
fig. 2 is a schematic bottom structure diagram of a convex-concave gasket of a steam turbine according to the present invention.
The elastic buffer ring comprises a convex buffer ring 1, a concave groove fixing piece 2, a concave groove fixing piece 3, a threaded opening 4, a deformation groove 5, a fastening piece 6 and an elastic buffer ring.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following embodiments, and the technical features or the connection relations of the present invention, which are not described in detail, are the prior art adopted.
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-2, the technical scheme adopted by the utility model is as follows: the utility model provides a steam turbine convex-concave packing ring, includes protruding buffering circle 1, recess stationary blade 2, screw thread mouth 3, deformation groove 4, mounting plate 5 and elastic buffering circle 6, protruding buffering circle 1 is located on mounting plate 5, recess stationary blade 2 is located protruding buffering circle 1, screw thread mouth 3 is located on recess stationary blade 2, the bottom of protruding buffering circle 1 is located to deformation groove 4, elastic buffering circle 6 is located one end and is located the bottom of mounting plate 5, the below of mounting plate 5 and 5 contactless with mounting plate are located to the other end of elastic buffering circle 6, protruding buffering circle 1 is located between mounting plate 5 and the recess stationary blade 2, recess stationary blade 2 is located between screw thread mouth 3 and the protruding buffering circle 1, mounting plate 5 is located between protruding buffering circle 1 and the elastic buffering circle 6.
The threaded port 3 is arranged in a circular opening.
The convex buffer ring 1 is arranged in a conical shape.
The groove fixing piece 2 is arranged in a circular ring shape.
The deformation groove 4 is arranged in a circular groove shape.
The section of the elastic buffer ring 6 is trapezoidal.
The convex buffer ring 1, the groove fixing piece 2, the fastening piece 5 and the elastic buffer ring 6 are made of 304 stainless steel.
When the device is used specifically, a user penetrates a screw used for fastening from a threaded opening 3 and slowly screws the device to be fixed, at the moment, the elastic buffer ring 6 is in contact with the fastening device, when the user screws the screw to the device which cannot be continuously screwed by hand, the screw is screwed again by using tools such as a screwdriver and the like, at the moment, under the screwing pressure, the elastic buffer ring 6 begins to be gradually flattened, when the elastic buffer ring 6 is flattened to be the most flat, the convex buffer ring 1 begins to be stressed and generates a deformation trend towards the periphery, when the pressure is greater than the supporting strength of the convex buffer ring 1, the convex buffer ring 1 begins to deform, at the moment, the deformation generated under the control of the deformation groove 4 can not damage the convex-concave gasket, when the user also cannot screw by using the screwdriver, the convex-concave gasket is completely fixed on the fastening device and can not loosen due to high resilience force.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
