Description

Technical Field

[0001] This utility model relates to the field of connection equipment technology, specifically to an oil filter inlet / outlet conversion device. Background Technology

[0002] When overhauling a transformer, it is necessary to change the oil using an oil filter. The oil change operation generally consists of four steps: the crude oil from the transformer is discharged to the oil tank through the oil filter; the crude oil in the oil tank is circulated and filtered through the oil filter; the filtered crude oil in the oil tank is introduced back into the transformer through the oil filter; and the transformer oil level is adjusted. Since the oil filter has a fixed function and only one inlet and outlet for each, the oil change operation requires frequent plugging and unplugging of pipelines to connect the corresponding equipment and complete the relevant operations. The plugging and unplugging process is time-consuming and increases the workload. It is also impossible to avoid a large amount of air coming into contact with the transformer oil and entering the transformer, affecting the transformer's insulation performance.

[0003] Patent CN218474989U discloses an oil filter inlet / outlet switching device, including an inlet manifold and an outlet manifold connected to the oil filter's inlet and outlet respectively. The other end of the inlet manifold is connected to an oil tank inlet pipe and a transformer inlet pipe, respectively. The other end of the outlet manifold is connected to an oil tank outlet pipe and a transformer outlet pipe, respectively. Two valves are installed on each of the oil tank inlet pipe, transformer inlet pipe, oil tank outlet pipe, and transformer outlet pipe. The valves on the oil tank inlet pipe and the transformer outlet pipe are connected via a straight-through connection, and the valves on the transformer inlet pipe and the oil tank outlet pipe are connected adjacently via a straight-through connection. This invention allows for oil change operations simply by switching between valves, making operation convenient and ensuring good sealing during the oil change process.

[0004] However, the device does not disclose the connection method between the oil filter interface pipe and the oil delivery pipe. In the existing technology, the oil filter interface pipe and the oil delivery pipe are mostly connected and fixed by clamps. However, the clamps need to be tightened by turning the bolts to lock and fix the pipe during use, which is a rather cumbersome operation. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an oil filter inlet / outlet switching device, solving the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an oil filter inlet / outlet conversion device, comprising an oil filter interface pipe, a connecting pipe, and a connector. The connector has a mating cavity. The connecting pipe is sleeved on the outside of the oil filter interface pipe. The connector is sleeved on the outside of the mating point between the connecting pipe and the oil filter interface pipe. The connector has two symmetrical protrusions. Each protrusion has two symmetrical sliding holes communicating with the mating cavity. A sliding rod is slidably arranged within each sliding hole. The mating cavity has two symmetrical sliding chambers. Each sliding chamber has two symmetrical arc-shaped frames. Rubber abutments are provided on the sides of the two arc-shaped frames that are close to each other. The two arc-shaped frames are respectively connected to two symmetrical sliding rods on the same axis. Each sliding chamber has two symmetrical receiving cavities. Each receiving cavity has a return spring. One end of the return spring abuts against the inner wall of the receiving cavity, and the other end abuts against the arc-shaped frame. A movable block is rotatably mounted on each protrusion, and the movable block is locked and fixed to the protrusion by a locking mechanism.

[0009] Preferably, the protrusion has a rectangular groove, and a hinge is rotatably installed in the rectangular groove, with the movable block installed on the hinge.

[0010] Preferably, the locking mechanism includes two symmetrical reset grooves on the movable block, a locking rod is slidably arranged in the reset groove, and two symmetrical locking holes adapted to the locking rod are provided on the protrusion.

[0011] Preferably, the locking rod has a protruding limiting ring, the size of which is adapted to the reset slide groove.

[0012] Preferably, a compression spring is sleeved on the locking rod, with one end of the compression spring abutting against the inner wall of the reset slide groove and the other end of the compression spring abutting against the limiting ring.

[0013] Preferably, the two locking rods are connected to the same mounting plate, and a pull ring is movably connected to the mounting plate.

[0014] Preferably, the cross-section of the movable block is L-shaped.

[0015] Compared with the prior art, this utility model provides an oil filter inlet / outlet conversion device with the following advantages: Through the cooperation of an arc-shaped frame, rubber clamping blocks, sliding rods, and movable blocks, this utility model allows for the connection of the oil filter interface pipe and connecting pipe. The connecting piece can be fitted onto the oil filter interface pipe, and the connecting pipe can be inserted into the gap between the oil filter interface pipe and the connecting piece's inner cavity. At this point, rotating the two movable blocks a certain angle allows them to contact and push the sliding rod, which in turn drives the arc-shaped frame towards the connecting... The pipe moves in the direction of movement and presses against the connecting pipe. At this time, the rubber abutment block on the arc frame deforms and presses the connecting pipe against the oil filter interface pipe, while ensuring a certain degree of sealing. Due to the two sets of linear array arc frames and rubber abutment blocks set in the connector, the connection between the oil filter interface pipe and the connecting pipe is more stable and secure compared to the single-channel fixing of traditional clamps. At this time, the movable block and the protrusion can be locked and fixed by the locking mechanism, thereby realizing the quick connection between the oil filter interface pipe and the connecting pipe. The whole process is simple and quick, improving assembly efficiency. Attached Figure Description

[0025] Please see Figure 1-5 An oil filter inlet / outlet switching device includes an oil filter interface pipe 1, a connecting pipe 2, and a connector 3. The connector 3 has a mating cavity 6. The connecting pipe 2 is sleeved on the outside of the oil filter interface pipe 1, and the connector 3 is sleeved on the outside of the mating point between the connecting pipe 2 and the oil filter interface pipe 1. The connector 3 has two symmetrical protrusions 4, and each protrusion 4 has two symmetrical sliding holes 16 communicating with the mating cavity 6. A sliding rod 10 is slidably arranged within each sliding hole 16. The mating cavity 6 has two symmetrical sliding cavities 17, and a sliding rod 10 is slidably arranged within each sliding cavity 17. Two symmetrical arc-shaped frames 13 are provided, and rubber abutment blocks 14 are provided on the side of the two arc-shaped frames 13 that are close to each other. The two arc-shaped frames 13 are respectively connected to two sliding rods 10 that are on the same axis and symmetrical to each other. Two symmetrical receiving cavities 11 are opened in the sliding cavity 17. A return spring 12 is provided in the receiving cavity 11. One end of the return spring 12 abuts against the inner wall of the receiving cavity 11, and the other end of the return spring 12 abuts against the arc-shaped frame 13. A movable block 5 is rotatably installed on the protrusion 4. The movable block 5 is locked and fixed to the protrusion 4 by a locking mechanism.

[0026] Through the coordinated arrangement of the arc-shaped frame 13, rubber abutment block 14, sliding rod 10, and movable block 5, when connecting the oil filter interface pipe 1 and the connecting pipe 2, the connector 3 can be fitted onto the oil filter interface pipe 1, and then the connecting pipe 2 can be inserted into the gap between the oil filter interface pipe 1 and the connecting cavity 6 inside the connector 3. At this time, the two movable blocks 5 are rotated at a certain angle and made to fit against the surface of the protrusion 4. The movable blocks 5 can then contact and push the sliding rod 10, which in turn drives the arc-shaped frame 13 to move towards the connecting pipe 2 and abut against it. This allows the rubber abutment block 14 on the arc frame 13 to deform and press the connecting pipe 2 against the oil filter interface pipe 1, while also ensuring a certain level of sealing. Due to the two sets of linear array arc frames 13 and rubber abutment blocks 14 set in the connector 3, the connection between the oil filter interface pipe 1 and the connecting pipe 2 can be more stable and secure compared to the single-channel fixing of traditional clamps. At this time, the movable block 5 and the protrusion 4 can be locked and fixed by the locking mechanism, thereby achieving a quick connection between the oil filter interface pipe 1 and the connecting pipe 2. The whole process is simple and quick, improving assembly efficiency.

[0027] Preferably, a rectangular groove 7 is provided on the protrusion 4, and a hinge 9 is rotatably installed in the rectangular groove 7, with the movable block 5 installed on the hinge 9.

[0028] The hinge 9 allows the movable block 5 to rotate at a certain angle along the rectangular groove 7 via the hinge 9.

[0029] Preferably, the locking mechanism includes two symmetrical reset grooves 18 on the movable block 5, a locking rod 19 is slidably arranged in the reset groove 18, and two symmetrical locking holes 22 are provided on the protrusion 4 that are adapted to the locking rod 19.

[0030] By setting the reset slide 18 and the locking rod 19, it is easy to lock and fix the protrusion 4 and the movable block 5 by inserting the locking rod 19 into the locking hole 22.

[0031] Preferably, a limiting ring 20 is protruding on the locking rod 19, and the size of the limiting ring 20 is adapted to the reset slide groove 18.

[0032] By cooperating with the limiting ring 20 and the reset slide 18, the movement range of the locking rod 19 can be limited, preventing the locking rod 19 from disengaging from the movable block 5.

[0033] Preferably, a compression spring 21 is sleeved on the locking rod 19, with one end of the compression spring 21 abutting against the inner wall of the reset slide groove 18 and the other end of the compression spring 21 abutting against the limiting ring 20.

[0034] By setting the compression spring 21, the limiting ring 20 can always be pressed against the inner wall of the reset slide groove 18 under normal conditions, thereby ensuring that one end of the locking rod 19 is always inserted into the locking hole 22, thus ensuring the connection stability between the movable block 5 and the protrusion 4.

[0035] Preferably, the two locking rods 19 are connected to the same mounting plate 15, and a pull ring 8 is movably connected to the mounting plate 15. By pulling the pull ring 8, the mounting plate 15 can drive the two locking rods 19 to slide in the reset slide groove 18, thereby unlocking the protrusion 4 and the movable block 5.

[0036] Preferably, the cross-section of the movable block 5 is L-shaped, which can better fit the protrusion 4 and allow the locking rod 19 to be inserted into the locking hole 22 on the side of the protrusion 4.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
