Description

Technical Field

[0001] The utility model relates to the field of compressor oil pumps, in particular to an oil filter connector of an oil pump. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Among the entire compressor components, the compressor oil pump is an important component to ensure the stable operation of the compressor, and the efficient operation of the compressor oil pump is inseparable from the use of clean oil. Therefore, the compressor oil pump is usually equipped with an oil filter to clean the oil.

[0003] The Chinese utility model patent with announcement number CN220877957U discloses an easy-to-install oil removal filter, which realizes the function of balancing the air pressure inside and outside the oil tank on the return oil filter, reduces the steps of installing the breathing valve, and is convenient for disassembly inspection and replacement. Although it achieves the purpose of reducing the steps of installing the breathing valve and facilitating disassembly inspection and replacement, the oil inlet joint pipe of this type of oil filter is often directly exposed to the environment. It is affected by external friction and oil pollution in the workshop environment. Mechanical debris, oil solidified blocks and other dirt are often easily accumulated at the joint pipe mouth, which enters the interior of the oil filter during subsequent oil filling, affecting the quality of the oil.

[0004] Therefore, an oil filter connector for an oil pump is provided to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides an oil filter connector for an oil pump, aiming to solve the problem in the background technology that the oil filter connector of the existing compressor oil pump is usually exposed to the outside, affected by mechanical impurities and oil pollution in the workshop environment, and enters the inside of the oil filter during subsequent oil filling, affecting the quality of the oil pollution.

[0007] (II) Technical solution

[0008] To achieve the above object, the utility model provides the following technical solutions: an oil filter joint of an oil pump, comprising an oil inlet joint pipe and an oil outlet joint pipe fixedly mounted on an oil filter, a flange for connecting to a compressor oil pump fixedly mounted on the oil outlet joint pipe, and a protective mechanism for protecting the head end of the oil inlet joint pipe provided on the outer side wall of the oil inlet joint pipe;

[0009] In order to solve the problem that the oil filter joint of the existing compressor oil pump is usually exposed to the outside, affected by mechanical impurities and oil pollution in the workshop environment, and enters the oil filter during subsequent oil injection, affecting the quality of oil pollution, the protective mechanism includes a fixed baffle fixedly installed on the outer wall of the oil inlet joint pipe and a movable baffle sleeved on the outer wall of the oil inlet joint pipe, a bellows sleeved on the oil inlet joint pipe and protecting it is fixedly installed between the fixed baffle and the movable baffle, a sponge pipe sleeve for wrapping and protecting the outside of the oil inlet joint pipe is movably installed in the bellows, and a sponge pipe sleeve for wrapping and protecting the outside of the oil inlet joint pipe is sleeved on the outside of the oil inlet joint pipe.

[0028] The protective mechanism 5 includes a fixed baffle 51 fixedly mounted on the outer wall of the oil inlet joint pipe 2 and a movable baffle 52 sleeved on the outer wall of the oil inlet joint pipe 2, a bellows 53 sleeved on the oil inlet joint pipe 2 and protecting the same is fixedly mounted between the fixed baffle 51 and the movable baffle 52, and a sponge tube sleeve 54 for wrapping and protecting the outside of the oil inlet joint pipe 2 is movably mounted inside the bellows 53.

[0029] When in use, a corrugated tube 53 made of plastic material is sleeved on the outside of the oil inlet joint pipe 2 to cover the outside of the oil inlet joint pipe 2, and a sponge tube sleeve 54 is sleeved between the outside of the oil inlet joint pipe 2 and the inside of the bellows 53 to further protect the oil inlet joint pipe 2. When the oil inlet joint pipe 2 is not in use, the movable baffle 52 is pulled to make the sponge tube sleeve 54 and the bellows 53 cover the head end of the oil inlet joint pipe 2, so that it is not directly exposed to the environment, and the influence of the workshop environment is reduced. The sponge tube sleeve 54 can wipe off part of the oil stains to prevent the oil stains from solidifying at the end of the oil inlet joint pipe 2, thereby reducing mechanical impurities and oil solidification block debris from entering the oil filter, reducing the impact on the oil quality.

[0030] A spring 55 sleeved on the outside of the bellows 53 is fixedly installed between the fixed baffle 51 and the movable baffle 52 .

[0031] During use, when the oil inlet joint pipe 2 is being filled with oil, the movable baffle 52 is pushed backwards, and the movable baffle 52 compresses the spring 55 to leak out the oil inlet joint pipe 2. After the oil filling is completed, the movable baffle 52 is released, and the spring 55 automatically rebounds, so that the movable baffle 52 drives the bellows 53 and the sponge tube sleeve 54 to automatically cover and protect the oil inlet joint pipe 2, saving time and effort.

[0032] Furthermore, the outer wall of the movable baffle 52 is movably mounted with a connecting plate 56 sleeved on the oil inlet joint pipe 2, and at least three threaded holes 57 are evenly arranged on the connecting plate 56.
