[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 A split type shell structure of a refrigerator refrigeration compressor, comprising an upper shell assembly, a lower shell assembly and a protection assembly, the upper shell assembly comprises an upper shell body 1 and a terminal block 2, one side of the upper shell body 1 is provided with the terminal block 2, the lower shell assembly comprises a lower shell body 3 and a base 4, the lower shell body 3 is provided with the base 4 at four corners below, and a docking pipe 5 is further provided above the lower shell body 3, a docking groove matched with the docking pipe 5 is provided below the upper shell body 1, a protection assembly for protecting the terminal block 2 is further provided on the upper shell body 1, the protection assembly comprises a protection cover 6, a protection shell 7 and a connecting piece, the protection shell 7 is arranged on the side of the terminal block 2, a blocking ring 14 is further arranged on the inner side of the protection shell 7 away from one end of the upper shell body 1, the protection shell 7 is inserted with the protection cover 6, connecting pieces connected with the protection shell 7 are further arranged on both sides of the protection cover 6, and a through hole is arranged below the protection shell 7.

[0023] The upper shell body 1 in the upper shell assembly serves as a structure for containing and protecting internal components (such as part of the motor assembly, the upper part of the compression mechanism, etc.) and bearing the terminal block 2, and the terminal block 2 arranged on one side thereof is used for connecting external power supply and related control lines, so that the compressor can normally receive electric energy and operate according to control instructions. The docking groove arranged below the upper shell body 1 is a key part for connecting the lower shell assembly, and through the insertion and cooperation with the docking pipe 5 above the lower shell body 3, the assembly of the upper shell assembly and the lower shell assembly is realized, forming a complete compressor shell, which provides a protection space for the internal motor assembly, compression mechanism, etc., and ensures the stability of the entire shell structure to cope with vibration and possible impact force during the operation of the compressor;

[0024] The base 4 arranged at four corners below the lower shell body 3 of the lower shell assembly mainly serves to provide a stable support base for the entire compressor. When the compressor is placed at a designated position in the refrigerator, the base 4 is in contact with the mounting plane in the refrigerator, evenly disperses the weight of the compressor, so that the compressor can be placed stably, preventing shaking, tilting and other situations caused by unstable placement. Moreover, when the compressor operates and vibrates, the base 4 absorbs and buffers part of the vibration by virtue of its structure and material properties (usually materials with certain elasticity or shock absorption capacity), reduces the transmission of vibration to the overall structure of the refrigerator, reduces the noise of the refrigerator caused by the vibration of the compressor, ensures the stable operation of the compressor, and prolongs the service life of the compressor and other parts of the refrigerator;

[0025] The protective shell 7 in the protection assembly is arranged on the side of the terminal block 2, which forms a protection space around the terminal block 2 to protect the terminal block 2 from all directions. The inside of the protective shell 7 is provided with a stop ring 14 away from one end of the upper shell body 1, which further blocks dust, water vapor and other foreign matters from entering the terminal block 2. In the use environment of the refrigerator, there are dust, a small amount of water vapor and other substances, the protective shell 7 and the stop ring 14 can prevent these external substances from approaching the electrical connection components such as the wire joint and the terminal in the terminal block 2, avoid the electrical short circuit caused by the accumulation of dust, and the rust and corrosion of the components caused by the invasion of water vapor, etc., to ensure the reliability and stability of the electrical connection in the terminal block 2, and ensure that the compressor can normally receive electric energy and operate according to the control requirements;

[0026] The protective cover 6 and the protective shell 7 are connected in a plug-in manner, and a connecting piece is used to realize the stable detachable connection function.

[0027] In the embodiment, the connecting piece includes a bearing block 8, an elastic piece and a clamping block 9, the left and right sides of the protective cover 6 are also symmetrically provided with the bearing block 8, the protective cover 6 is provided with a movable slot penetrating the bearing block 8, the two ends of the elastic piece are connected with the inner wall of the movable slot and the clamping block 9 respectively, the left and right sides of the protective shell 7 are symmetrically provided with clamping holes matched with the clamping block 9, the elastic piece includes a spring 10 and an extension rod 11, the spring 10 is sleeved on the extension rod 11, the two ends of the spring 10 and the extension rod 11 are connected with the inner wall of the movable slot and the clamping block 9 respectively, and the front and rear sides of the clamping block 9 are symmetrically provided with inclined surfaces.

[0028] The bearing block 8 in the connecting piece is arranged on the left and right sides of the protective cover 6, which provides a mounting and supporting basis for the elastic piece and the clamping block 9. The movable slot penetrating the bearing block 8 arranged on the protective cover 6 provides space for the extension and retraction of the clamping block 9. The two ends of the elastic piece (composed of the spring 10 and the extension rod 11 sleeved thereon) are connected with the inner wall of the movable slot and the clamping block 9 respectively. When the protective cover 6 is inserted into the protective shell 7, the clamping block 9 will retract into the movable slot along the inclined surface when it contacts the side of the protective shell 7 (at this time, the spring 10 is compressed) during the insertion process. When the clamping block 9 moves to the position corresponding to the clamping hole on the protective shell 7, the clamping block 9 is ejected and clamped into the clamping hole under the elastic force of the spring 10, thereby realizing the firm connection of the protective cover 6 and the protective shell 7, making the protective cover 6 tightly cover on the protective shell 7, further enhancing the protection effect of the terminal block 2, preventing external factors from affecting the terminal block 2 from above and other angles. When it is necessary to disassemble the protective cover 6, the clamping block 9 can be easily taken out of the clamping hole by pressing it (overcoming the elastic force of the spring 10), so that the protective cover 6 can be easily taken off, which is convenient for maintenance personnel to check, maintain and operate the terminal block 2, such as checking whether the wiring is loose, replacing the damaged terminal, etc.

[0029] In actual use, the protective cover 6 is further provided with a handle 12 away from the upper shell body 1, which facilitates the insertion and extraction of the protective cover 6, and the protective cover 6 is further provided with a connecting rope 13 connected with the protective shell 7, which facilitates the prevention of the protective cover 6 from falling and being lost.
