Description
Technical Field
The utility model belongs to the field of tools, relates to a disassembly and assembly tool, and particularly relates to an engine filter element disassembly and assembly tool applicable to a narrow space.
Background
In recent years, with the rapid development of society, power machines such as automobiles, tractors, engineering machines and the like which adopt engines as power are spread over vast urban and rural areas of China. In use, engine maintenance is becoming more and more important, and particularly, disassembly and assembly of engine filter elements are more common.
In the dismouting maintenance of engine filter core, the filter core assembly and disassembly tools that use mainly have two kinds of structures: one is of a cloth belt type, and the other is of a sleeve ratchet type. The former is suitable for places with larger space positions around the filter element after the engine is installed on the host machine, the latter is suitable for places with a polygonal filter element end part, the filter element end part cannot be used when the polygonal filter element end part is not provided with the polygonal filter element, and one filter element needs to be provided with one sleeve. It can be seen that the above two structures have limitations in the disassembly tools. The diesel filter and the engine oil filter of the high-pattern tire tractor engine are narrow in surrounding space positions, and the filter element dismounting tool with the two structures cannot meet dismounting requirements.
The patent of the utility model, a large cylindrical surface elastic wrench for use, which is authorized by the national intellectual property agency on 2015, 8, 19 days, has the application number of: 20151200883133. X, grant bulletin number: CN 204565995U; the application date is as follows: 5 days of 2015, 2 months. An elastic wrench for large cylindrical surfaces is disclosed. The elastic spanner provided by the utility model adopts a circular pressure head and an annular belt compression cylindrical surface part with two ends fixed on a spanner body, wherein a spanner handle is provided with threads and penetrates through a screw hole of the spanner body; the wrench handle is rotated to enable the pressure head to move forwards and backwards, so that the cylindrical surface part is pressed or loosened; the handle is rotated to rotate the cylindrical surface part. The scheme solves the defect that the conventional wrench in the prior art cannot clamp or clamp the cylindrical part unstably. However, for cylindrical parts mounted in small parts, such as oil filter cartridges and diesel filter cartridges on high-pattern tire tractor engines, it is difficult to fit the belt over the cartridges because the belt is soft. Even if the ring belt is changed into the steel belt, the filter element can be sleeved, but the disassembly and assembly tool can not be rotated in a looping way due to the small space around the filter element, so that the disassembly and assembly of the filter element are still very difficult.
In summary, in order to solve the problem of disassembly and assembly of the engine filter element and the diesel filter element on the engine of the high-pattern tire tractor, it is necessary to provide an engine filter element disassembly and assembly tool applicable to a narrow space.
