Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

A head gasket 100 for a compressor 200 according to an embodiment of the present invention is described below with reference to fig. 1 to 8.

The compressor 200 includes a compressor main machine. The head gasket 100 for the compressor 200 of the embodiment of the present invention has a first surface 101 and a second surface 102 opposite to each other in the thickness direction of the head gasket 100, the first surface 101 being provided with a plurality of cavities 1 arranged at intervals. In other words, the cover gasket 100 has a plurality of cavities 1, and the plurality of cavities 1 are opened at the first surface 101 at intervals. Each cavity 1 comprises a main machine cavity portion 11, each main machine cavity portion 11 having a plurality of receiving sections for receiving the top of a different sized compressor 200 main machine. That is, each of the main body cavity portions 11 has a plurality of accommodating sections 110 capable of accommodating the top of the compressor main body 201 of different sizes, i.e., the size of the compressor main body 201 that each of the accommodating sections 110 can accommodate may be different from the size of the compressor main body 201 that another of the accommodating sections 110 can accommodate.

The cover gasket 100 for a compressor of the embodiment of the present invention has the advantage of improving the versatility of the cover gasket 100 by providing the host cavity 11 with a plurality of receiving sections 110 for receiving the top of the host of the compressors 200 of different sizes, the compressors 200 of different sizes being adapted to the receiving sections of different sizes.

In addition, compared with the mode of packaging the compressors individually (i.e. each compressor has an individual package), the cover pad 100 for the compressor 200 according to the embodiment of the invention is provided with a plurality of cavities 1 arranged at intervals on the first surface 101, so that the advantages of saving packaging materials and reducing packaging cost are achieved; the compressor 200 can be packaged in batches, and the packaging efficiency of the compressor 200 is greatly improved.

Therefore, the cover gasket 100 for the compressor of the embodiment of the invention has the advantages of improving the operation efficiency of the packing compressor 200 and reducing the packing cost. In addition, the cover pad has the advantage of good universality.

As shown in fig. 1 and 6, a plurality of receiving sections are arranged in the thickness direction of the head gasket 100, and an edge of each of the adjacent two receiving sections adjacent to the opening in the thickness direction (C direction in fig. 6 is the thickness direction of the head gasket 100) is located outside an edge of one of the adjacent two receiving sections distant from the opening in the thickness direction, and an abutment surface 15 capable of coming into contact with the top surface of the main body of the compressor 200 is formed between the adjacent receiving sections.

For example, when the plurality of accommodating sections are substantially the same, the cross-sectional areas of the plurality of accommodating sections decrease in the opening direction of the cavity 1 to the opening direction away from the cavity 1, the rim of each of the adjacent two accommodating sections adjacent to the opening in the thickness direction is located outside the rim of one of the adjacent two accommodating sections distant from the opening in the thickness direction; the cross-sectional area of the plurality of receiving segments decreases in the direction from the first surface 101 to the second surface 102.

In the cover gasket 100 for a compressor according to the embodiment of the present invention, by reducing the cross-sectional area of the plurality of receiving sections along the direction from the first surface 101 to the second surface 102 so as to form an abutment surface capable of contacting with the top surface of the main unit of the compressor 200 between the adjacent receiving sections, the side wall sizes of the top parts of the main units corresponding to the compressors 200 with different sizes are often different (may be the top parts of the compressors, i.e., the top covers of the compressors), and in the process of packaging the main units in particular, the top surfaces of the main units corresponding to the compressors 200 can be adaptively abutted with the different abutment surfaces. For example, when the size of the top of the packing compressor is required to be large, the top of the compressor is in contact with the opening accommodation section near in the thickness direction, and when the size of the top of the packing compressor is required to be small, the top of the compressor is in contact with the opening accommodation section far in the thickness direction. Therefore, the cover gasket 100 of this structure has advantages of simple structure and strong applicability.

In addition, by decreasing the cross-sectional area at the plurality of receiving sections along the direction of the first surface 101 to the second surface 102, there is an advantage of saving space with respect to being disposed in the width or length direction of the cover pad 100.

Specifically, the main machine cavity portion 11 includes a first cavity section 111, a second cavity section 112, and a third cavity section 113, the cross-sectional area of the first cavity section 111 is smaller than the cross-sectional area of the second cavity section 112, the cross-sectional area of the second cavity section 112 is smaller than the cross-sectional area of the third cavity section 113, so that a first abutment surface 151 is formed between the first cavity section 111 and the second cavity section 112, a second abutment surface 152 is formed between the second cavity section 112 and the third cavity section 113, and the first abutment surface 151 or the second abutment surface 152 can be in contact with the top surface of the main machine of the compressor 200. In other words, the first, second and third chamber sections 111, 112, 113 constitute a plurality of accommodation sections for accommodating the tops of different sizes of compressor hosts (201).

According to the cover gasket 100 for the compressor, disclosed by the embodiment of the invention, the main machine cavity part 11 comprises the first cavity section 111, the second cavity section 112 and the third cavity section 113, so that the structural strength of the first abutting surface and the second abutting surface can be ensured under the condition that the thickness of the cover gasket 100 is certain, the packing operation of compressors 200 with various sizes and types can be met, and the cover gasket has the advantages of high structural strength and good general effect.

Optionally, each of the first, second and third cavity sections 111, 112, 113 are substantially identical. For example, as shown in fig. 6, each of the first chamber section 111, the second chamber section 112, and the third chamber section 113 is circular-hole-shaped, and the central axis of the first chamber section 111, the central axis of the second chamber section 112, and the central axis of the third chamber section 113 coincide. The central axis of the first cavity section 111, the central axis of the second cavity section 112 and the central axis of the third cavity section 113 may all extend in the thickness direction of the cover gasket 100.

As shown in fig. 7, the compressor 200 further includes a reservoir 202, and each cavity 1 further includes a reservoir cavity portion 12 for accommodating a top portion of the reservoir 202, and the main body cavity portion 11 and the reservoir cavity portion 12 of each cavity 1 are disposed at a spacing.

As shown in fig. 2 and 6, the reservoir cavity 12 includes a circular segment 122 and a spherical segment 121 disposed in this order in the thickness direction of the cover pad, the circular segment 122 being adjacent to the first surface with respect to the spherical segment 121, the circular segment 122 being for accommodating a main body portion of the reservoir 202, and the spherical segment 121 being for accommodating a top portion of the reservoir 202.

Optionally, the spherical segment 121 is in contact with the top of the reservoir 202.

It will be appreciated that the bracket relief chamber portion 13 is capable of receiving the support bracket 204 of the compressor 200.

According to the cover gasket 100 for the compressor, provided by the embodiment of the invention, the support avoidance cavity part 13 for avoiding the support frame 204 of the compressor 200 is arranged, so that avoidance can be formed for the support frame 204 of the compressor 200, and compressors with more types and sizes can be applied, and the universality of the cover gasket 100 is further improved.

As shown in fig. 1 to 7, each of the depth of the host cavity portion 11 and the depth of the reservoir cavity portion 12 is greater than the depth of the bracket escape cavity portion 13 so as to form the support portion 3 between the host cavity portion 11 and the reservoir cavity portion 12.

The cover gasket 100 for a compressor according to the embodiment of the present invention is formed by forming the support portion 3 between the main body cavity portion 11 and the reservoir cavity portion 12. The structural strength of the host cavity part 11 and the liquid reservoir cavity 1 can be ensured while avoiding the supporting frame 204 of the compressor 200, so that the problem that the deformation of the cavity is overlarge due to extrusion of the host cavity part 11 and the liquid reservoir cavity 1 is avoided, and the structural strength and the universality of the cover gasket 100 are further improved.

As shown in fig. 1 to 7, a plurality of cavities 1 are arranged in a matrix so as to constitute a plurality of cavity columns. Therefore, the integrity of the structure of the cover gasket 100 is improved, the matching of the tops of the compressors and the cavities in one-to-one correspondence can be realized more easily, and the packaging is convenient.

Specifically, the maximum cross-sectional area of the main body cavity 11 is larger than the maximum cross-sectional area of the reservoir cavity 12, and a plurality of cavity rows are arranged at intervals in the longitudinal direction (e.g., the left-right direction in fig. 4) of the cover gasket 100, and the main body cavity 11 and the reservoir cavity 12 of each cavity row are alternately arranged at intervals in the width direction. The main body cavity 11 and the reservoir cavity 12 of the adjacent cavity rows are disposed opposite to each other in the longitudinal direction of the cover gasket 100.

According to the cover gasket 100 for the compressor, the main machine cavity parts 11 and the liquid storage device cavity parts 12 of each cavity row are alternately arranged at intervals along the length direction, and the main machine cavity parts 11 and the liquid storage device cavity parts 12 of the adjacent cavity rows are oppositely arranged along the length direction of the cover gasket 100; the stability of the structure between the host cavity part 11 and the liquid storage device cavity part 12 between each adjacent cavity 1 can be ensured, the interference between the compressor 200 and the adjacent compressor 200 can be avoided, the arrangement density of the cavities 1 is improved, the loading capacity of the compressor 200 is further improved, and the device has the advantage of saving freight.
