Description

Technical Field

[0001] The utility model relates to an oil filter disassembly device and belongs to the field of filter disassembly equipment. Background Art

[0002] The oil filter is installed on the front accessory bracket of the water-cooled diesel engine, which is mainly used to filter impurities in the oil to ensure the normal lubrication of the oil inside the engine. When the diesel engine is overhauled, the oil filter needs to be replaced. The existing removal tool 10 of the oil filter is as follows Figure 2 As shown, it includes a rotating handle and a rotating ring arranged at the end of the handle. The rotating ring is made of metal, and the inner ring is set as a polygon, and the structure is similar to a hexagonal wrench. Figure 3 As shown, the operator puts the tool on the polygonal position of the bottom of the oil filter, adjusts the position of the rotating ring so that it clamps the bottom of the oil filter, and then rotates the handle to remove the oil filter.

[0003] However, due to the long intervals between diesel engine overhauls and the long service life of the oil filter, the connection with the base is prone to rust, making it difficult to rotate using existing disassembly tools. In addition, the metal surface of the oil filter is thin, and the rotating ring, which is made of a harder material, is easily damaged during rotation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an oil filter disassembly device with a simple structure. By arranging two upper and lower movable clamping plates and two steel belts, the friction between the disassembly device and the oil filter to be disassembled is increased, thereby achieving the purpose of efficiently and quickly disassembling the oil filter. At the same time, the provision of the flexible steel belt can prevent damage to the metal surface of the oil filter during disassembly.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An oil filter disassembly device comprises a bracket and two steel belts respectively arranged at the top and bottom of the bracket, and the two ends of each steel belt are fixed on the bracket in a ring-shaped arrangement, and each steel belt is also provided with a clamping plate for expanding and shrinking the steel belt ring by pushing a bolt, a threaded hole is provided on the bracket, and a nut II matching the bolt is fixed at the threaded hole, and the end of the bolt passes through the nut II and contacts the clamping plate, and the bracket is also provided with a handle.

[0007] A further improvement of the technical solution of the utility model is that the clamping plate includes a fixed plate in the middle and an arc-shaped plate located at the upper and lower ends of the fixed plate and having an arc-shaped contact surface with the oil filter, and both ends of the fixed plate are provided with slender strip holes through which the steel belt can pass, and the end of the bolt is in contact with the fixed plate.

[0008] A further improvement of the technical solution of the utility model is that a loose nut I is installed at the front end of the bolt.

[0009] A further improvement of the technical solution of the utility model is that: the arc surface of the arc plate is provided with a sawtooth structure.

[0010] A further improvement of the technical solution of the utility model is that the thickness of the arc plate is 1.5 mm.

[0011] A further improvement of the technical solution of the utility model is that a large number of concave points are stamped on the part of the steel belt that contacts the oil filter.

[0012] A further improvement of the technical solution of the utility model is that the thickness of the steel strip is 1 mm and the width is 20 mm.

[0013] A further improvement of the technical solution of the utility model is that the bracket is arranged in an I-shape, including a support rod in the middle and two upper and lower cross bars, and the ends of the steel belt are respectively fixed to the two ends of the cross bar.

[0014] A further improvement of the technical solution of the utility model is that: the handle is fixed on the support rod of the bracket, and the fixing method is welding.

[0015] A further improvement of the technical solution of the utility model is that the end of the steel belt is fixed to the cross bar by rivets.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0017] The utility model is suitable for disassembling longer-sized oil filters. The upper and lower ends of the oil filter are wrapped and fixed by two upper and lower clamping plates and two matching steel belts. This structural design makes the contact area between the utility model and the oil filter to be disassembled wider and the friction greater, saving time and effort during disassembly. At the same time, the disassembly friction is dispersed into the upper and lower parts, and the flexible wrapping of the steel belt is conducive to protecting the thin-walled oil filter.

[0018] The utility model, through the matching arrangement of the clamping plate and the bolt, can increase the friction between the clamping plate and the outer surface of the oil filter by increasing the surface pressure by rotating the bolt and the nut I clockwise, so that disassembly is more labor-saving.

[0019] The clamping plate of the utility model is not fixed and can move freely on the steel belt, is suitable for oil filters of different sizes, and has a wider application range.

[0020] The clamping plate of the utility model has a double-layer arc structure. The arc-shaped design makes the clamping plate and the oil filter fit better and more firmly, which is conducive to increasing the friction between the two. In addition, the serrated structure on the arc surface can further increase the friction between the clamping plate and the oil filter, making disassembly more labor-saving.

[0021] The bent portion of the steel belt of the utility model is provided with a large number of concave points by means of a stamping technology, thereby increasing the friction force between the steel belt and the outer surface of the oil filter.

[0022] The utility model has a simple structure, light overall weight and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
