Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the following description of the preferred embodiments of the present invention is given with reference to the accompanying examples, but it should be understood that the drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

Example 1:

as shown in fig. 1 to 5, a stamping cylinder cover with a stopper for a refrigerator compressor comprises a cover body 1 and a valve plate 2, wherein the valve plate 2 is arranged in the cover body 1; the cover body 1 is provided with a limiter 11, and the limiter 11 is embedded on the cover body 1; the valve plate 2 is arranged below the limiting stopper 11.

The utility model reduces the number of parts of the compressor, simplifies the structure of the original compressor and reduces the cost of the compressor by directly arranging the position limiter 11 in the cover body 1; will valve block 2 sets up the below of stopper 11 can effectively restrict the lifting angle of valve block 2, need not set up dedicated limit structure simultaneously on the valve block 2, reduction in production cost.

Further, in another embodiment, an elastic body 21 and a cover plate 22 are arranged on the valve plate 2, an installation plate 23 is arranged at one end of the elastic body 21, and the cover plate 22 is fixed below the other end of the elastic body 21.

The cover plate 22 is fixed below the elastic body 21, which causes small deformation of the elastic body 21, and this deformation can make the cover plate 22 cover the exhaust port of the compressor well.

Further, in another embodiment, the middle of the elastic body 21 is provided with a bending device.

The cover plate 22 can be better covered on the exhaust port of the compressor by bending the middle part of the elastic body 21, the sealing performance of the compressor is improved, and the processing difficulty of the valve plate where the exhaust port is located can be greatly reduced.

Further, in another embodiment, the minimum distance between the elastic body 21 and the stopper 11 is between 1 and 2mm, and the minimum distance is at the highest point of the elastic body 21.

The lifting range of the valve block 2 is limited within 1-2 mm, and the best effect of the compressor can be achieved during air exhaust.

Further, in another embodiment, the elastic body 21 and the cover plate 22 are fixed by welding or bonding.

The elastic body 21 and the cover plate 22 are welded, so that the connection strength is high, but if the cover plate 22 is damaged, the cover plate 22 cannot be replaced independently, only the whole valve plate 2 can be replaced, and the cost is high; the elastic body 21 and the cover plate 22 are bonded, so that the connection strength is lower than that of welding, but the damaged cover plate 22 can be replaced, and the cost is lower.

The utility model discloses a theory of operation of an embodiment as follows:

a stamping cylinder cover with a limiter for a refrigerator compressor is characterized in that when air is exhausted, air flow jacks up a cover plate 22 on a valve plate 2, when an elastic body 21 is in contact with the limiter 11, the cover plate 22 cannot be lifted up any more, and the limiter 11 plays a role in limiting the lifting of the valve plate 2; when the exhaust is finished, the cover plate 22 seals the exhaust hole, and because the bending of the elastic body 21 is arranged, the cover plate 22 can better seal the exhaust hole.
