Description

Technical Field

[0001] This utility model relates to a maintenance tool for diesel vehicles, specifically a tool for removing and installing an iron ring filter element. Background Technology

[0002] Diesel vehicles are equipped with corresponding oil and diesel filters to ensure the proper use of diesel fuel and lubricating oil. These filters are mostly cylindrical and require periodic or irregular replacement or maintenance. Among existing tools for disassembling and installing filter cartridges, there is a notched ring type. Its main structure consists of a notched ring with pins connected to both ends, which in turn connect to a handle. The handle has a square hole for inserting a wrench. In use, the notched ring is inserted into the filter cartridge, and the wrench is inserted into the square hole and turned, tightening or loosening the filter cartridge (see patent CN209648583U for details). This tool has a problem that causes it to slip frequently, preventing quick and effective tightening of the filter cartridge. Specifically, there is a rotating rod between the two pins. This rotating rod is connected to the two pins via a connecting rod. When the handle is turned, the connecting rod swings around this rotating rod as a fulcrum, pulling or loosening the two pins, thus tightening or loosening the filter cartridge. Because the lever swings with the connecting rod when it is turned, the fulcrum is not fixed, the force on the hand cannot be fully transmitted to the ring, it cannot tighten properly and is easy to slip.

[0003] Because diesel vehicles are equipped with multiple filters, and the environments in different parts vary, this notched ring-shaped tool has a unique purpose and cannot be replaced by other tools. Therefore, improving or developing new ring-shaped disassembly and assembly tools is of practical significance. Summary of the Invention

[0004] Therefore, this utility model proposes an iron ring filter element disassembly and assembly tool, which has a simple and reasonable structure, and the iron ring can quickly and effectively tighten the filter element cylinder without slipping or damaging the filter element cylinder, thereby overcoming the shortcomings of the prior art.

[0005] The objective of this utility model is achieved through the following means: A tool for disassembling and assembling an iron ring filter element includes a notched iron ring and a torque block. The notched iron ring has two ends connected to the torque block via a left pin and a right pin, respectively. The bearing seat of the left pin is fixed on the torque block, and the left pin is connected to the left end of the notched iron ring. The right pin passes through the torque block, and the bearing seat of the right pin is fixed to the right end of the notched iron ring. The torque block has a square hole for inserting a wrench, and the square hole is located outside the line connecting the two pins.

[0006] The right end of the notched iron ring is connected by a connecting bent plate, and the right pin seat is fixed on the outside of the connecting bent plate.

[0007] The connecting bend is an arc-shaped plate adapted to the filter cartridge.

[0008] The left end of the connecting bend plate tapers inward from the outer side.

[0009] The torque block has a semi-circular groove that mates with the left pin and a pin hole through which the right pin passes.

[0010] The left and right pin seats are nut pairs welded to the torque block and the connecting elbow, respectively, and the left and right pins have corresponding threads.

[0011] The nut pair consists of two nuts, one above the other, welded together vertically.

[0012] The notched iron ring can be made of metal or plastic.

[0013] The torsion block is made of steel.

[0014] To avoid confusion, it is hereby declared that the notched iron ring described in this utility model does not specifically refer to a ring made of iron, but rather to a notched ring made of, but including but not limited to, iron materials. Filter element and filter cartridge are synonyms.

[0015] This utility model is used as follows: When using, place the notched iron ring on the filter cartridge, then insert the standard wrench into the square hole of the torque block. The operator only needs to turn the wrench handle back and forth to achieve continuous unidirectional rotation through the wrench, without having to remove the wrench from the filter cartridge, until the filter cartridge is loosened or tightened in place.

[0016] This invention eliminates the rotating rod found in existing similar tools, reducing the number of pins from three to two, thus simplifying and improving the structure. When the torque block is turned, it directly transmits the torsional force to the notched iron ring, tightening the filter cartridge from both sides to prevent slippage. Furthermore, the torque block changes the direction of force, enabling unidirectional intermittent drive, allowing continuous rotation within a limited swing space, improving assembly and disassembly efficiency and reducing operational difficulty.

[0017] Meanwhile, the circular ring of this invention achieves 360-degree large-area contact with the filter element shell, resulting in uniform stress distribution and fundamentally avoiding the risk of filter element shell deformation or damage caused by stress concentration.

[0018] This invention can be adapted to oil and diesel filters for various brands and models of vehicles by designing notched iron rings with different inner diameters. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown. The notched iron ring 3 can be made of sheet metal 1-3mm thick, and the connecting bend plate 2 can be made of a slightly thicker piece of the same material, with the right end of the notched iron ring welded to the center of the end face of the connecting bend plate. The torque block 1 is made of steel, with the wrench square hole 6 running through both the top and bottom surfaces. The left pin groove 102 is a semi-circular groove adapted to the left pin, and the right pin hole 101 is slightly larger than the right pin.

[0027] As mentioned above, components such as torsion blocks, notched iron rings, and connecting bends are not limited to being made of iron; they can also be made of other materials with suitable strength.

[0028] The left pin seat 5 can be a pair of nuts. The left end of the notched iron ring is first welded to the left pin 7 and then the pair of nuts are twisted to the upper and lower ends of the left pin. The left pin is placed into the left pin groove 102 and finally the pair of nuts are welded to the torque block.

[0029] First, insert the right pin 8 into the right pin hole 101 of the torque block. Then, twist the right pin seat nut to both ends of the right pin and finally weld the right pin seat nut to the connecting elbow. In this way, when the torque block is turned with a wrench, the torque block can swing around the right pin as the axis, thereby pulling the left end of the notched iron ring to tighten and move the filter element cylinder.

[0030] Components and designations not mentioned are as described above.

[0031] The connecting elbow allows for smooth contact when the notched iron ring tightens around the filter element, better protecting the filter element surface. It also makes the connection of the right pin seat more rational and the force more evenly distributed. However, this does not mean that the technical solution of directly welding the right pin seat to the right end of the notched iron ring without a connecting elbow is excluded from the protection scope of this utility model.
