The general rotary compressor (detailed in the description attached figure 1) mainly comprises a top cover assembly, a shell assembly, a stator, a rotor, a pump, a foot rest, a filter bottle, a bottom cover and other parts. The core parts of the compressor are a pump and a motor (a stator and a rotor), and the basic working principle is as follows: the stator is fixed at the inside unable motion of shell, and after the compressor circular telegram, can produce the magnetic field between rotor and the stator, leads to the rotor to rotate, because of the pumping eccentric shaft is fixed by the heat jacket in the rotor internal diameter, so the rotor can drive the eccentric shaft and carry out rotary motion. So that the eccentric shaft rotates in the pump to perform liquid compression on the refrigerant in the cylinder. When the compressed refrigerant meets a certain pressure, the upper support riveted valve plate is squeezed open, leaks through the upper support discharge port, and then flows into a system for refrigeration through the compressor outlet pipe. The existing upper support valve block is riveted and fixed by a cylindrical riveting column (see the attached figures 2 and 3 of the specification for details), and the valve block cannot move after riveting. However, the present invention finds: if the valve plate has small angle deflection in the riveting process, the valve plate cannot play a role in sealing the discharge port of the upper support, and the refrigerant inside the pump directly leaks in the compression process.

Secondly, the utility model provides another kind of rotary compressor pumping upper bracket includes equally: the upper support, the riveting column and the valve plate; the upper support is provided with a discharge port, one end of the valve block is provided with a riveting column hole, the valve block is riveted on the upper support through the matching of the riveting column hole and the riveting column, and the other end of the valve block covers the discharge port and is used for shielding the discharge port; the riveting column is formed by fixedly connecting the side surfaces of two cylinders in a tangent mode, and the shape of the riveting column hole is matched with the outline of the riveting column, so that the riveting column can just enter the riveting column hole.
As a further technical scheme, the rivet column hole is formed by externally cutting two round holes, and the two round holes are communicated through tangent positions, so that the shape of the rivet column hole is matched with the outline of the rivet column, and the rivet column can just enter the rivet column hole.
As a further technical scheme, the interior of the riveting column is of a hollow structure so as to reduce material cost.
Thirdly, the utility model discloses a rotary compressor pumping, it contains the utility model relates to an upper bracket.
Compared with the prior art, the utility model discloses following beneficial effect has been obtained:
(1) the riveting column with the polygonal structure can effectively ensure that the valve block cannot generate angle deflection after being installed, thereby avoiding the hidden danger of leakage after the valve block is riveted; because the utility model discloses a this kind of polygonized structure's riveting post can not make the valve block rotate around riveting the post and produce the angle beat like traditional cylindrical riveting post, polygonized structure's riveting post can be through the rotation of the effective restraint valve block of edge, and then prevents the angle beat, still has the hidden danger of leaking under no pressure extruded condition after avoiding the valve block riveting.
(2) The utility model discloses a rivet post by the tangent fixed formation in two cylindrical sides has the effect that the restriction valve block rotated and produced the angle beat around riveting the post equally, and then still has the hidden danger of leaking under the extruded condition of no pressure after avoiding the valve block riveting.
