Description

Technical Field

[0001] This utility model relates to the field of oil filter cart technology, and in particular to an adapter structure for an oil filter cart. Background Technology

[0002] During operation, hydraulic oil in hydraulic equipment can become contaminated with impurities, particles, and moisture, affecting the equipment's performance and lifespan. To ensure the cleanliness of the hydraulic oil, regular filtration of the hydraulic system is typically required. An oil filter cart is a commonly used mobile oil filtration device that can circulate and filter hydraulic oil on-site, avoiding the cumbersome process of disassembling the oil tank or moving the equipment to a dedicated maintenance location. It is suitable for the maintenance of various engineering machinery, industrial equipment, and hydraulic systems.

[0003] When connecting existing oil filtration carts to hydraulic equipment, they typically require connecting to the hydraulic oil port via a hose. Because different models of hydraulic equipment vary significantly in port size, thread specifications, and connection methods, operators often need to select the appropriate connecting pipe fittings based on the specific equipment model. For example, some hydraulic equipment uses threaded connections, while others use quick-connect, flange, or other special interface types. To accommodate these different interfaces, on-site maintenance personnel need to carry multiple sizes of connecting fittings and change them as needed during operation. This not only increases workload but also easily leads to problems such as lost or confused fittings. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of inconvenient use of oil filter cart connectors in the prior art, and to propose an oil filter cart adapter structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adapter structure for an oil filtration cart includes a connector assembly connected to the oil filtration cart via a pipeline. The connector assembly includes a housing with a first chamber and a second chamber inside. The pipeline connects to the second chamber. At least two types of external connectors are slidably connected to the housing. The external connectors have a first state and a second state. In the first state, the external connector connects to the first chamber. In the second state, the external connector connects to the second chamber, and the connector head of the external connector in the second state protrudes from the connector head of the external connector in the first state.

[0007] The external component includes a rigid tube that is slidably connected to the housing. One end of the rigid tube has an inlet hole on its outer periphery, and the other end of the rigid tube has the connector. Sliding the rigid tube allows the inlet hole to move to the first chamber or the second chamber.

[0008] The box body includes a partition and an end plate. The partition divides the internal chamber of the box body into a first chamber and a second chamber. The box body has a liquid inlet in the second chamber. The pipeline is connected to the liquid inlet. The rigid pipe slides through the partition and the end plate. O-rings are provided between the rigid pipe and the partition and the end plate.

[0009] The rigid tube has a limiting head at one end located in the first chamber.

[0010] The oil filter cart adapter structure proposed in this utility model has the following advantages: by integrating multiple different types of external connectors into the same box and designing a sliding switching structure, the required type of external connector can be quickly connected by simply pulling it out to the second state. Unused external connectors remain in the first state, with their connectors positioned lower than those in operation, so as not to interfere with the external connectors in use. This effectively avoids the cumbersome steps of changing connectors on site, reduces the risk of loss and confusion, and improves the efficiency and convenience of oil filtration operations.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-2 An oil filter cart adapter structure includes a connector assembly connected to an oil filter cart 1 via a pipeline 2. The connector assembly includes a housing 11, which has a first chamber 12 and a second chamber 13. The pipeline 2 connects to the second chamber 13. At least two types of external connectors 14 are slidably connected to the housing 11. The external connectors 14 have a first state and a second state. In the first state, the external connectors 14 are connected to the first chamber 12. In the second state, the external connectors 14 are connected to the second chamber 13. The connector head 6 of the external connectors 14 in the second state protrudes from the connector head 6 of the external connectors 14 in the first state.

[0016] Reference Figure 2This structure includes an oil filter cart 1, pipelines 2, a housing 11, a first chamber 12, a second chamber 13, external connectors 14, and a connector 6. Pipeline 2 connects to the second chamber 13. Multiple external connectors 14 of different models are slidably mounted on the housing 11. Each external connector 14 has a first state and a second state. When the external connector 14 is in the first state, its internal oil passage is connected to the first chamber 12 and does not flow into the second chamber 13. When the external connector 14 is in the second state, its internal oil passage is connected to the second chamber 13, and oil can enter the external connector 14 through pipeline 2 and be output to external equipment through connector 6. In use, the operator selects the required external connector 14 according to the equipment interface model, slides the external connector 14 outward to the second state, and connects its connector 6 to the target equipment, thus connecting the oil filter cart 1 to the equipment's oil passage.

[0017] By integrating multiple different models of external connectors into the same housing and designing a sliding switching structure, users can quickly connect the desired model of external connector by simply pulling it out to the second state. Unused external connectors remain in the first state, with their connectors positioned lower than those in use, so as not to interfere with the external connectors in use. This effectively avoids the tedious steps of changing connectors on-site, reduces the risk of loss and confusion, and improves the efficiency and convenience of oil filtration operations.

[0018] The external connector 14 includes a rigid tube 4, which is slidably connected to the housing 11. One end of the rigid tube 4 has an inlet hole 5 on its outer periphery, and the other end of the rigid tube 4 has a connector 6. Sliding the rigid tube 4 can move the inlet hole 5 to the first chamber 12 or the second chamber 13.

[0019] The external connector 14 consists of a rigid tube 4, which is slidably connected to the housing 11. One end of the rigid tube 4 has an inlet hole 5 on its outer periphery, and the other end has a connector 6. When the rigid tube 4 slides outward, the inlet hole 5 can move from the first chamber 12 to the second chamber 13. When the inlet hole 5 is in the first chamber 12, the external connector 14 is in its first state and is not connected to the oil circuit of the oil filter cart 1. When the inlet hole 5 slides into the second chamber 13, the external connector 14 is in its second state, and the oil enters the inlet hole 5 through the second chamber 13, is transported through the rigid tube 4 to the connector 6, and then output to external equipment through the connector 6. The sliding fit design of the rigid tube 4 allows the external connector 14 to switch between the two states through simple linear movement. The structure is compact and the operation is intuitive; the change in the position of the inlet hole 5 directly controls the connection and disconnection of the oil circuit.

[0020] The box body 11 includes a partition 9 and an end plate 10. The partition 9 divides the internal chambers of the box body 11 into a first chamber 12 and a second chamber 13. The box body 11 is provided with a liquid inlet 8 in the second chamber 13. The pipeline 2 is connected to the liquid inlet 8. The rigid pipe 4 slides through the partition 9 and the end plate 10. The rigid pipe 4 is provided with an O-ring 7 between the partition 9 and the end plate 10. The rigid pipe 4 is provided with a limiting head 3 at one end in the first chamber 12.

[0021] The housing 11 is composed of a partition 9 and an end plate 10. The partition 9 divides the internal space of the housing 11 into a first chamber 12 and a second chamber 13. The second chamber 13 is provided with a liquid inlet 8 and is connected to the oil filter cart 1 through a pipeline 2. The rigid pipe 4 slides through the partition 9 and the end plate 10, and O-rings 7 are installed between the partition 9 and the end plate 10 to achieve sealing during the sliding process and prevent oil leakage. When the rigid pipe 4 slides and the liquid inlet 5 enters the second chamber 13, the oil can enter the interior of the rigid pipe 4 through the liquid inlet 8 and the second chamber 13, and then be transported to external equipment through the connector 6. A limit head 3 is provided at one end of the rigid pipe 4 located in the first chamber 12, which plays a position limiting role when the rigid pipe 4 slides, preventing the rigid pipe 4 from moving excessively out of or detaching from the housing 11. The partition 9 and end plate 10 ensure the functional independence of the first chamber 12 and the second chamber 13 through their separation and sealing structure. The O-ring 7 effectively seals the sliding parts, guaranteeing the reliability of the oil delivery process. The limit head 3 effectively prevents the rigid pipe 4 from accidentally slipping out, improving operational safety and durability, and ensuring the oil filter cart 1 maintains a stable and reliable working state during the switching of multiple external components.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
