Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to a buffer protection base for an oil filter. Background Art

[0002] The oil filter, also known as the oil grid, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. Oil filters are divided into full-flow and split-flow types; the full-flow filter is connected in series between the oil pump and the main oil channel, so it can filter all the lubricating oil entering the main oil channel; the split-flow filter is connected in parallel with the main oil channel and only filters part of the lubricating oil delivered by the oil pump.

[0003] Vehicles often experience large bumps during driving, which in turn cause large vibrations. Once they are in this state of continuous vibration for a long time, it will have a certain degree of adverse effects on the filter. The existing oil filter lacks effective buffering protection, which can easily cause the filter to loosen. In severe cases, it may even cause the filter element to slide and fall off, resulting in the filter being unable to function normally.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1 - Figure 5 As shown, a buffer protection base for an oil filter comprises a base plate 1, which is an arbitrary structure fixed inside a car, and its function is to connect and fix a base plate 2. The outer side of the base plate 1 is fixedly connected with the base plate 2, and an oil filter 3 is placed inside the base plate 2. By sleeved on the outer side of the oil filter 3, the base plate 2 protects the outer side of the oil filter 3 to prevent the oil filter 3 from directly colliding with external objects, causing damage and affecting the use. A compression spring 2 16 is fixedly connected inside the base 2, and a support plate 17 is provided on the base 2. The compression spring 2 16 is fixedly connected to the support plate 17, and the support plate 17 is threadedly connected to the bottom end of the oil filter 3. The compression spring 2 16 cooperates with the support plate 17 to buffer the bottom end of the oil filter 3. A fine thread 401 is provided on the outer side of the oil filter 3, and a ring strip 5 is fixedly connected to the inner wall of the base 2. A fine thread 2 402 matching the fine thread 401 is provided on the outer side of the ring strip 5.

[0024] An oblique groove is provided through the outer side of the base 2, and the oblique groove is arranged in a circular array with the center of the base 2 as the center. A limiting cylinder 6 is fixed in the oblique groove by spot welding, and an abutment rod 7 is slidably connected in the limiting cylinder 6. An abutment sleeve 8 is fixedly connected to one end of the abutment rod 7 located inside the base 2, and a push rod 9 is slidably connected in the abutment sleeve 8. A compression spring 1 is provided on the inner wall of the abutment sleeve 8, and the two ends of the compression spring 1 are fixedly connected to the push rod 9 and the inner wall of the abutment sleeve 8 respectively.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, the limiting cylinder 6 is inclined, so that the abutting rod 7 sliding inside is also inclined, the abutting rod 7 slides in the limiting cylinder 6 and drives the abutting sleeve 8 to move synchronously, and the abutting sleeve 8 drives the push rod 9 to move synchronously. The push rod 9 adaptively abuts against the outer wall of the oil filter 3 under the action of the compression spring 1. Since the abutting rod 7 is inclined, the push rod 9 provides an inclined downward pressing force to the outer wall of the oil filter 3. The inclined downward pressing force is analyzed, that is, a horizontal thrust and a vertical downward thrust are provided to the oil filter 3, as shown in FIG. Figure 2 As shown in the perspective, the oil filter 3 remains more stable during use.

[0026] One end of the abutment rod 7 located outside the base 2 is fixedly connected to a bevel slider 10, a fine pitch thread 3 403 is provided on the outer side of the base 2, a rotating sleeve 11 is threadedly connected to the outer side of the base 2 through the fine pitch thread 3 403, a sliding frame 12 is provided on the outer side of the base 2, an annular groove 13 is provided on the outer side of the rotating sleeve 11, and one end of the sliding frame 12 is slidably connected in the annular groove 13.

[0027] The sliding frame 12 is fixedly connected with inclined slide rails 14 whose number matches the inclined slide blocks 10. The inclined surfaces of the inclined slide blocks 10 are slidably connected in the inclined slide rails 14. A positioning sleeve 15 is fixedly mounted on the outer side of the base 2. One end of the sliding frame 12 is slidably connected in the positioning sleeve 15.

[0028] During the specific setting, the oil filter 3 is placed in the base 2, the fine pitch thread 1 401 is threadedly connected with the fine pitch thread 2 402, and the bottom of the oil filter 3 is threadedly connected with the support plate 17, thereby realizing the preliminary fixation of the oil filter 3, and then the rotating sleeve 11 is rotated. The rotating sleeve 11 drives the sliding frame 12 to move axially along the outer side of the base 2 during the rotation process. Since the inclined slide rail 14 is always slidably connected with the inclined slide block 10, it is ensured that the sliding frame 12 will not rotate during the axial movement. During the axial movement, one end of the sliding frame 12 slides in the positioning sleeve 15. By setting the positioning sleeve 15, the positioning sleeve 15 further guides and assists the movement of the sliding frame 12, thereby avoiding the problem of vibration affecting the accuracy of the sliding frame 12 during the movement;

[0029] The shape of the inclined slider 10 is as follows Figure 4As shown, the inner wall of the inclined slide rail 14 is also set to a slope that matches the slope of the inclined slider 10, so that when the sliding frame 12 drives the inclined slide rail 14 to move, the inclined surface of the inclined slider 10 is squeezed by the inclined surface of the inner wall of the inclined slide rail 14, and then the abutment sleeve 8 and the push rod 9 are driven to move synchronously through the abutment rod 7 until the push rod 9 contacts and presses against the outer wall of the oil filter 3. When the rotating sleeve 11 rotates in the opposite direction, the push rod 9 releases the pressure on the oil filter 3, thereby realizing flexible disassembly of the oil filter 3.
