Description

Technical Field

[0001] The utility model relates to the technical field of compressor accessories, in particular to a compressor shell structure. Background Art

[0002] The refrigerator compressor is the core component of the refrigerator. Its main function is to absorb low-temperature and low-pressure refrigerant gas, increase the temperature and pressure through compression, and turn it into high-temperature and high-pressure gas. Then, these high-temperature and high-pressure gases release heat in the condenser and condense into liquid, thereby achieving the purpose of lowering the internal temperature of the refrigerator through the circulation of refrigerant inside the refrigerator.

[0003] A refrigerator compressor is usually composed of a shell, a motor, a cylinder, a piston, and control devices (such as a starter and a thermal protector). The shell of a refrigerator box compressor is an important component of the compressor and has the key function of supporting and protecting the internal structure of the compressor. Structurally, the compressor shell is usually made of strong and durable materials, such as cast iron or aluminum alloy, and is installed and fixed using a traditional bolt fixing structure. As we all know, refrigerator compressors are usually installed at the bottom of the refrigerator casing. During later inspection and maintenance, operators are often required to bend over or even operate close to the ground. The traditional bolt fixing structure used in the casing requires operators to find and unscrew the bolts one by one, which prolongs the time for operators to bend over and operate close to the ground, which is time-consuming and laborious, and the operation is not convenient enough. For this reason, the present application proposes a compressor shell structure to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a compressor housing structure, wherein the assembled compressor can be easily disassembled or installed during subsequent maintenance, without the need for tools such as wrenches, and is more conducive to maintenance.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A compressor housing structure comprises a compressor main housing and a mounting base plate; two foot plates are symmetrically fixed to the bottom of the compressor main housing, a fixed clamping sleeve is fixed to one end of the top of the mounting base plate, and a movable clamping sleeve is movably connected to the other end of the top of the mounting base plate, and grooves for horizontal insertion of the foot plates are provided on the facing sides of the fixed clamping sleeve and the movable clamping sleeve, and a pushing member capable of driving the movable clamping sleeve to approach the fixed clamping sleeve is provided on the mounting base plate.

[0007] Preferably, a positioning bolt is threadedly passed through the movable sleeve, and a positioning hole adapted to be plugged into the positioning bolt is opened on the foot plate.

[0008] Preferably, mounting ear plates are fixed at the four corners of the compressor main housing, mounting bolts are arranged on the mounting ear plates, and rubber sleeves and nuts are sleeved on the mounting bolts.

[0009] Preferably, the pushing member includes a baffle bar arranged on an end of the upper surface of the mounting base plate away from the fixed clamping sleeve and a spring vertically arranged between the baffle bar and the movable clamping sleeve.

[0010] Preferably, a plurality of springs are arranged side by side, and a guide rod is inserted into each of the springs. The guide rod movably passes through the baffle bar, and the end of the guide rod is fixedly connected to the movable sleeve.

[0011] Preferably, the corners of the two foot plates which are away from each other at one end are provided with arc chamfers, and the upper surface of the movable ferrule is provided with a protrusion.

[0012] Preferably, a slide groove is provided on the upper surface of the mounting base plate, and a connecting block which is slidably fitted into the slide groove is provided at the bottom of the movable clamping sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model cooperates the fixed sleeve and the movable sleeve on the installation base plate with the foot plate sleeve at the bottom of the compressor main shell. During the initial installation, the installation base plate is fixed in the refrigerator casing. In the subsequent maintenance process, the main shell of the compressor can be taken out by only twisting the positioning bolt to disengage from the positioning hole and pushing the movable sleeve to disengage from the foot plate, and the movable sleeve is pushed away from the fixed sleeve, and the main shell of the compressor is pushed so that one of the foot plates is inserted into the fixed sleeve. After loosening the movable sleeve, the movable sleeve is pushed close to the fixed sleeve under the elastic force of the spring, so that the movable sleeve is inserted on the other foot plate, and the positioning bolt is twisted to insert and position with the positioning hole on the foot plate, and the installation of the main shell of the compressor is completed. Compared with the method of directly fixing the main shell of the compressor with multiple bolts, this structural method can easily remove or install the main shell of the compressor in the later stage, which is more conducive to maintenance.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0023] Example

[0024] See also Figures 1 to 5 , the utility model preferably provides a technical solution:

[0025] The cam 2 is provided with a plurality of movable sleeves 5, each of which is provided with a plurality of movable sleeves 5, each of which is provided with a plurality of movable sleeves 5. The movable sleeves 5 are provided with a plurality of movable sleeves 5 which are provided with a plurality of movable sleeves 5. The movable sleeves 5 are provided with a plurality of movable sleeves 5 which are provided with a plurality of movable sleeves 5.

[0026] In this embodiment, a positioning bolt 13 is threaded through the movable sleeve 5, and a positioning hole 8 which is plugged into and adapted to the positioning bolt 13 is opened on the foot plate 3. After the movable sleeve 5 and the foot plate 3 are clamped, the positioning bolt 13 is screwed into the positioning hole 8 to relatively position the movable sleeve 5 and the foot plate 3, thereby realizing the positioning installation of the compressor main housing 1.

[0027] In this embodiment, mounting ear plates 7 are fixed at the four corners of the compressor main housing 1, and mounting ear plates 7 are provided with mounting bolts 15. The mounting bolts 15 are sleeved with rubber sleeves 16 and nuts 17. By combining the mounting bolts 15, rubber sleeves 16 and nuts 17, the mounting base plate 2 can be fixed in the refrigerator casing, wherein the rubber sleeves 16 play a buffering role.

[0028] As a preferred implementation manner of this embodiment, the pushing member 6 includes a baffle 12 arranged on the upper surface of the mounting base plate 2 away from one end of the fixed sleeve 4 and a spring 10 vertically arranged between the baffle 12 and the movable sleeve 5. Under the elastic force of the spring 10, the movable sleeve 5 can be pushed close to the fixed sleeve 4 to be sleeved on the foot plate 3, and this structural method can easily push the movable sleeve 5 away from the foot plate 3 to disassemble the compressor main housing 1.

[0029] In this embodiment, multiple springs 10 are arranged side by side, which are used to evenly push the movable clamping sleeve 5 to move. A guide rod 11 is inserted in each spring 10, and the guide rod 11 movably penetrates the baffle bar 12. The end of the guide rod 11 is fixedly connected to the movable clamping sleeve 5. The guide rod 11 is used to limit the spring 10 to prevent the spring 10 from bending, and can guide the movement of the movable clamping sleeve 5. The corners of the two foot plates 3 away from one end are provided with arc chamfers, and the upper surface of the movable clamping sleeve 5 is provided with a protrusion 14, which is conducive to the insertion of the foot plate 3 into the fixed clamping sleeve 4 and the clamping groove 9 on the movable clamping sleeve 5. A slide groove 18 is opened on the upper surface of the mounting base plate 2, and a connecting block 19 is provided at the bottom of the movable clamping sleeve 5 to slide and fit with the slide groove 18. Specifically, the connecting block 19 and the slide groove 18 are set as a ⊥-shaped structure, which plays a sliding limit effect on the movable clamping sleeve 5.

[0030] Working principle: When the compressor assembled in the compressor main housing 1 is installed for the first time, the mounting base plate 2 is fixed in the refrigerator casing by the cooperation of the mounting bolts 15, the rubber sleeve 16 and the nut 17, and then the protrusion 14 is pushed to drive the movable clamping sleeve 5 away from the fixed clamping sleeve 4. At this time, the compressor main housing 1 is placed above the mounting base plate 2, and the two foot plates 3 at the bottom of the compressor main housing 1 are fitted with the upper surface of the mounting base plate 2. Then, the compressor main housing 1 is pushed so that one of the foot plates 3 is inserted into the card slot 9 on the fixed clamping sleeve 4, and then the protrusion 14 is released, and the movable clamping sleeve 5 is pushed away from the fixed clamping sleeve 4 under the elastic force of the spring 10. The sleeve 5 is pressed against the fixed sleeve 4, so that the movable sleeve 5 is clamped on the other foot plate 3, and then the positioning bolt 13 is screwed and inserted into the positioning hole 8 on the foot plate 3 to complete the installation of the compressor main housing 1. When the compressor assembled on the compressor main housing 1 needs to be overhauled, it is only necessary to screw the positioning bolt 13 to disengage the positioning hole 8, and push the movable sleeve 5 to disengage from the foot plate 3, so that the compressor main housing 1 can be taken out. Compared with the method of directly fixing the compressor main housing 1 with multiple bolts, this structural method can easily dismantle or install the compressor main housing 1 in the later stage, which is more conducive to maintenance.
