Description

Technical Field

[0001] This utility model belongs to the field of air compressor technology, specifically relating to a four-cylinder air compressor that is simple to assemble and operate and has a stable structure. Background Technology

[0002] An air compressor is a device that converts mechanical energy into gas pressure energy, increasing the pressure of air through compression. It is widely used in industries such as manufacturing, construction, medicine, and energy. Currently, the assembly and disassembly of air compressors involves first securing the motor base, motor, and motor cover of the motor assembly with fasteners; then securing the positive pressure chamber, negative pressure chamber, and cylinder mounting plate of the cylinder assembly with fasteners; and finally, securing the motor assembly and cylinder assembly together with fasteners. This process results in significant waste of labor and time during the assembly and disassembly of the air compressor.

[0003] Because the piston reciprocates within the cylinder assembly, the assembly structure between components in the existing air compressor cylinder assembly is not stable enough and is prone to vibration, which seriously affects the equipment's lifespan, operational stability, and the safety of the surrounding environment. Utility Model Content

[0004] This addresses the technical problem of inconvenient operation during the assembly and disassembly of existing air compressors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a four-cylinder air compressor with simple assembly and stable structure, comprising a motor assembly and a cylinder assembly. The motor assembly includes a motor base, a motor, and a motor cover, with the motor disposed between the motor base and the motor cover. The cylinder assembly includes a positive pressure chamber, a negative pressure chamber, and a cylinder mounting plate. The positive pressure chamber is located at the top of the negative pressure chamber, and the cylinder mounting plate is located at the bottom of the negative pressure chamber. A screw passes through the positive pressure chamber and the negative pressure chamber and is screwed into the cylinder mounting plate. The cylinder mounting plate, the motor base, and the motor cover all have several protruding mounting portions along their edges, which are fixedly installed by screws passing through the mounting portions of the cylinder mounting plate, the motor cover, and the motor base.

[0006] The present invention has the following advantages: the cylinder mounting plate, the motor base and the edge of the motor cover are provided with several protruding mounting parts. The fixed installation is completed by passing the mounting parts of the cylinder mounting plate, the motor cover and the motor base through the screw, so that the motor assembly and the cylinder assembly are fixedly connected. The structure is simple, the operation is convenient, and it saves labor and time costs. Attached Figure Description

[0011] like Figures 1 to 4 As shown, a four-cylinder air compressor with simple assembly and stable structure includes a motor assembly 10 and a cylinder assembly 20. The motor assembly 10 includes a motor base 11, a motor 12, and a motor cover 13. The motor 12 is located between the motor base 11 and the motor cover 13. The cylinder assembly 20 includes a pair of positive pressure chambers 21, a pair of negative pressure chambers 22, and a cylinder mounting plate 23. The positive pressure chambers 21 are located at the top of the negative pressure chambers 22, and the cylinder mounting plate 23 is located at the bottom of the negative pressure chambers 22. A screw 101 passes through the positive pressure chambers 21 and the negative pressure chambers 22 and is screwed into the cylinder mounting plate 23 to complete the fixed installation between the positive pressure chambers 21, the negative pressure chambers 22, and the cylinder mounting plate 23.

[0012] The cylinder mounting plate 23, the motor base 11, and the motor cover 13 are all provided with several protruding mounting parts 102 along their edges. Each mounting part 102 is provided with a screw hole. The screw 101 passes through the mounting parts of the cylinder mounting plate 23, the motor cover 13, and the motor base 11 to complete the fixed installation, so that the motor assembly 10 and the cylinder assembly 20 are fixedly connected. The structure is simple, the operation is convenient, and it saves labor and time costs.

[0013] The motor 12 is fitted with a mounting cover 121 on its outer side. The mounting cover 121 has several reinforcing ribs 122 on its outer periphery. The top and bottom of the reinforcing ribs 122 are provided with connecting notches 123. The top of the mounting cover 121 is set in the motor cover 13 through the connecting notches 123, and the bottom of the mounting cover 121 is set in the motor base 11 through the connecting notches 123. The structure of the motor 12 mounted between the motor cover 13 and the motor base 11 is more stable.

[0014] A pair of positive pressure cylinders 30 are provided on both sides between a pair of positive pressure chambers 21, and a pair of negative pressure cylinders 40 are provided on both sides between a pair of negative pressure chambers 22. Each positive pressure cylinder 30 is equipped with a positive pressure valve plate 31. The top two sides of the positive pressure valve plate 31 are screwed into the positive pressure chambers 21 on both sides via screws 101. Each negative pressure cylinder 40 is equipped with a negative pressure valve plate 41. The bottom two sides of the negative pressure valve plate 41 are screwed into the negative pressure chambers 22 on both sides via screws 101. The bottom two sides are connected to the negative pressure air chamber 22 by screws 101. The top two sides of the negative pressure valve plate 41 are screwed to the positive pressure air chamber 21 by screws 101. The two positive pressure air chambers 21 are screwed together by the positive pressure valve plate 31, and the two negative pressure air chambers 22 are screwed together by the negative pressure valve plate 41. The positive pressure air chamber 21 and the negative pressure air chamber 22 are fixedly connected by the positive pressure valve plate 31 and the negative pressure valve plate 41 respectively, making the overall structure of the cylinder assembly 20 more stable and less prone to loosening.
