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 with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

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

The compressor 200 includes a compressor main body. The head gasket 100 for the compressor 200 according to the embodiment of the present invention has a first surface 101 and a second surface 102 opposite to each other in a thickness direction of the head gasket 100, and the first surface 101 is provided with a plurality of cavities 1 arranged at intervals. In other words, the head gasket 100 has a plurality of cavities 1, and the plurality of cavities 1 are spaced apart from each other on the first surface 101. Each cavity 1 includes a main body type cavity portion 11, and each main body type cavity portion 11 has a plurality of receiving sections for receiving tops of different sizes of the main bodies of the compressors 200. That is, each of the main body type chamber sections 11 has a plurality of accommodation sections 110 capable of accommodating the tops of the compressor hosts 201 of different sizes, that is, the size of the compressor host 201 that each of the accommodation sections 110 can accommodate may be different from the size of another compressor host 201 that the accommodation section 110 can accommodate.

The head gasket 100 for the compressor of the embodiment of the present invention has an advantage of improving the versatility of the head gasket 100 by having the mainframe cavity portion 11 have a plurality of receiving sections 110 for receiving the tops of the different-sized compressors 200, and the different-sized compressors 200 are adapted to the different-sized receiving sections.

In addition, compared with the way of individually packaging the compressors in the related art (i.e., each compressor has an individual package), the cover pad 100 for the compressor 200 according to the embodiment of the present invention has the advantages of saving packaging materials and reducing packaging cost by providing the first surface 101 with the plurality of cavities 1 arranged at intervals; the batch packaging operation of the compressor 200 can be realized, and the packaging efficiency of the compressor 200 is greatly improved.

Therefore, the cover pad 100 for the compressor according to the embodiment of the present invention has advantages of improving the working 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, the plurality of receiving sections are arranged in the thickness direction of the head gasket 100, the edge of each of the adjacent openings in the thickness direction (the C direction of 6 in the drawing is the thickness direction of the head gasket 100) of the adjacent two receiving sections is located outside the edge of one of the adjacent two receiving sections which is far from the opening in the thickness direction, and an abutting surface 15 capable of contacting the top surface of the main unit of the compressor 200 is formed between the adjacent receiving sections.

For example, when the general shapes of the plurality of housing sections are the same, the cross-sectional areas of the plurality of housing sections decrease along the opening direction of the cavity 1 to the opening direction away from the cavity 1, and the edge of each of adjacent two housing sections adjacent to the opening in the thickness direction is located outside the edge of one of adjacent two housing sections away from the opening in the thickness direction; the cross-sectional area of the plurality of receiving sections decreases in the direction from the first surface 101 to the second surface 102.

According to the head gasket 100 for the compressor of the embodiment of the invention, by reducing the cross-sectional area of the plurality of accommodating sections along the direction from the first surface 101 to the second surface 102 to form the abutting surface capable of contacting with the top surface of the main machine of the compressor 200 between the adjacent accommodating sections, the sizes of the side walls of the tops of the main machines corresponding to compressors 200 with different sizes are often different (possibly the tops of the compressors, namely the top covers of the compressors), and the top surface of the main machine corresponding to the compressor 200 can be adaptively abutted with different abutting surfaces in the process of packaging the main machine specifically. For example, when the size of the top portion of the packing compressor is required to be large, the top portion of the compressor is in contact with the accommodation section close to the opening in the thickness direction, and when the size of the top portion of the packing compressor is required to be small, the top portion of the compressor is in contact with the accommodation section far from the opening in the thickness direction. Therefore, the covering pad 100 of this structure has advantages of simple structure and strong applicability.

Furthermore, by reducing the cross-sectional area of the plurality of receiving sections in the direction from the first surface 101 to the second surface 102, there is an advantage of space saving with respect to the arrangement in the width or length direction of the head gasket 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 that of the second cavity section 112, the cross-sectional area of the second cavity section 112 is smaller than that of the third cavity section 113, so that a first abutting surface 151 is formed between the first cavity section 111 and the second cavity section 112, a second abutting surface 152 is formed between the second cavity section 112 and the third cavity section 113, and the first abutting surface 151 or the second abutting 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 cavity sections 111, 112 and 113 constitute a plurality of accommodation sections for accommodating tops of compressor bodies (201) of different sizes.

According to the cover pad 100 for the compressor, the main machine type cavity 11 comprises the first cavity section 111, the second cavity section 112 and the third cavity section 113, so that under the condition that the thickness of the cover pad 100 is constant, the structural strength of the first abutting surface and the second abutting surface is guaranteed, the packing operation of compressors 200 of various sizes and models can be met, and the cover pad 100 has the advantages of being high in structural strength and good in general effect.

Optionally, the general shape of each of the first, second and third cavity segments 111, 112, 113 is the same. For example, as shown in fig. 6, each of the first, second, and third cavity segments 111, 112, 113 is circular-hole shaped, and the central axes of the first, second, and third cavity segments 111, 112, 113 coincide. The central axis of the first cavity segment 111, the central axis of the second cavity segment 112, and the central axis of the third cavity segment 113 may all extend in the thickness direction of the head gasket 100.

As shown in fig. 2 and 6, the reservoir-type chamber portion 12 includes a circular segment 122 and a spherical segment 121 arranged in this order in the thickness direction of the cap pad, the circular segment 122 being close to the first surface with respect to the spherical segment 121, the circular segment 122 being for receiving a main body portion of the reservoir 202, and the spherical segment 121 being for receiving a top portion of the reservoir 202.

Alternatively, the wall of the circular segment 122 and the wall of the spherical segment 121 smoothly meet.

The cover pad 100 for the compressor according to the embodiment of the present invention can better accommodate and stabilize the top of the liquid reservoir 202 (the top of the liquid reservoir 202 has a unit with a spherical structure) by providing the circular segment 122 and the spherical segment 121, and is also applicable to the liquid reservoir 202 with a spherical structure, and has the advantages of simple structure, wide application range and good general effect.

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

As shown in fig. 1 and 2, each cavity 1 further includes a bracket avoiding cavity portion 13 for avoiding a support bracket 204 of the compressor 200, the bracket avoiding cavity portion 13 is opened on the first surface 101, and the bracket avoiding cavity portion 13 is communicated with the reservoir type cavity portion 12. It is understood that the bracket relief chamber portion 13 can accommodate the support bracket 204 of the compressor 200.

According to the cover mat 100 for the compressor, provided by the bracket avoiding cavity part 13 for avoiding the supporting frame 204 of the compressor 200, the supporting frame 204 of the compressor 200 can be avoided so as to be suitable for compressors of more models and sizes, and therefore the universality of the cover mat 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 type cavity portion 12 is larger than the depth of the rack escape cavity portion 13 so as to form the support portion 3 between the host cavity portion 11 and the reservoir type cavity portion 12.

The head gasket 100 for the compressor according to the embodiment of the present invention is formed by forming the support portion 3 between the main unit cavity portion 11 and the reservoir type cavity portion 12. Can guarantee host computer type chamber portion 11 and reservoir die cavity 1's structural strength when dodging compressor 200's support frame 204 to avoid host computer type chamber portion 11 and reservoir die cavity 1 to appear the too big problem of cavity deflection after because of the extrusion, further promoted the structural strength and the commonality of pad for covering 100.

Therefore, the structural integrity of the cover pad 100 is improved, the top of a plurality of compressors can be matched with a plurality of cavities in a one-to-one correspondence manner more easily, and the cover pad has the advantage of convenient packaging.

Specifically, the maximum cross-sectional area of the host cavity portion 11 is larger than the maximum cross-sectional area of the reservoir cavity portion 12, a plurality of cavity rows are arranged at intervals in the length direction (for example, the left-right direction in fig. 4) of the head gasket 100, and the host cavity portion 11 and the reservoir cavity portion 12 of each cavity row are alternately arranged at intervals in the width direction. The host cavity portion 11 and the reservoir cavity portion 12 of adjacent cavity rows are disposed opposite each other along the longitudinal direction of the head gasket 100.
