Description

Technical Field

[0001] The utility model relates to the technical field of vehicle maintenance tools, in particular to a flexible disassembly and assembly tool for a vehicle oil filter. Background Art

[0002] Our company's buses are all maintained and repaired in the company's internal auto repair shop. When maintaining the buses, the engine oil filter needs to be replaced, which involves tools for disassembling and installing the oil filter.

[0003] At present, most of the tools on the market are three-claw or sleeve-type. Since the oil filter of a bus needs to be tightened when installed, when the existing tools are used to disassemble and assemble the oil filter, the oil filter often slips at the contact position with the tool, making it impossible to disassemble, and the oil filter is worn and deformed at the contact position with the tool. In order to solve the above problems, a flexible disassembly and assembly tool for vehicle oil filters is designed.

[0004] In the prior art, Chinese patent document CN204640060U discloses a belt-type oil filter wrench. In the process of disassembling the oil filter, the two ends of the fastening belt are aligned and stacked together, inserted from one side of the slot hole at the torsion bar and exposed from the other side by an appropriate length, and then the fastening belt ring is sleeved on the outer surface of the oil filter, the torsion bar is rotated, the torsion bar is held with one hand, and the ratchet wrench is inserted into the torsion bar with the other hand, and the ratchet wrench is rotated until the oil filter is twisted off. Its characteristics are: simple structure, low cost, and it can conveniently and quickly disassemble the oil filter with excessive tightening torque or damaged and deformed; its disadvantages are: first, when the torsion bar is twisted, the stability of the torsion bar is poor; second, when the torsion bar is twisted, the torsion bar will abut against the oil filter. Since the torsion bar is a cylinder, and the oil filter, that is, the oil filter, is also a cylindrical structure, when the torsion bar abuts against the oil filter, due to line contact, the force area is small, which will cause the outer wall of the oil filter to deform.

[0007] A twisting portion is arranged after the lower end of the rotating shaft extends out of the ear seat.

[0008] A central shaft is rotatably installed at the bottom center of the cylinder, a screwing part is provided on the central shaft, the central shaft and the rotating shaft are connected for transmission through a gear structure, the gear structure includes a first gear and a second gear, the first gear is installed on the central shaft, the second gear is installed after the lower end of the rotating shaft extends out of the ear seat, and the first gear and the second gear are meshed.

[0038] See also Figure 1 , adjust the flexible belt 30 in the cylinder 10 so that the flexible belt 30 in the cylinder 10 forms a placement space 31. When disassembling the oil filter, the cylinder 10 is inserted into the lower end of the oil filter, and the oil filter enters the placement space 31 of the flexible belt 30.

[0039] Insert the wrench 70 into the screwing portion 60 at the lower end of the central shaft 40, and rotate the central shaft 40 by the wrench 70. The central shaft 40 drives the first gear 51 to rotate, and the first gear 51 drives the second gear 52 to rotate, thereby driving the rotating shaft 20 to rotate. The rotating shaft 20 wraps and tightens the flexible belt 30 to tightly fix the oil filter, and then further pulls the wrench 70 with force to twist and remove the oil filter.
