Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and particularly relates to a filter housing. Background Art

[0002] A filter is a component that filters impurities or gases through a filter paper. Different types of filters have different working principles, but generally, the removal of impurities is achieved through the physical filtration of the filter element. For example, the filter element of an air filter is usually made of materials such as filter paper and fibers, and has a microporous structure that can block particulate matter in the air; the filter elements of fuel filters and oil filters are mostly made of materials such as filter paper, filter screens or ceramics, and can effectively filter impurities in fuel and oil; when installing and disassembling a traditional fuel filter, the fuel outlet pipe and the filter are connected by threads, without other structures for assistance, and the overall rigidity is poor, requiring a high strength for the fuel outlet pipe; in addition, the installation location is mostly inside the corresponding equipment. When workers replace it, they need to manually reach into the machine with a small space to rotate the filter. However, there is a certain amount of oil in the filter. When the filter and the fuel outlet pipe are separated, a part of the engine oil will leak, polluting the environment inside the machine, and workers also need to carry out corresponding cleaning; the overall installation and disassembly are relatively inconvenient, and oil leakage also needs to be prevented; in view of the above problems, a filter housing that is convenient to install and reduces pollution is proposed. Content of the Utility Model

[0003] In order to solve the problems in the background art, the utility model provides a filter housing; it is more convenient for workers to perform maintenance and installation, and causes less environmental pollution to the inside of the machine.

[0004] A filter housing provided by the utility model includes a filter body. A sealing ring is fixedly installed at the inlet and outlet positions of the filter body. Threads are provided inside the sealing ring. An auxiliary installation component is provided on the filter body; the auxiliary installation component includes a groove on the outer surface of the filter body. An arc-shaped plate is slidably connected to the groove. Support plates are symmetrically and fixedly installed on the arc-shaped plate. A first straight slot is provided on the support plates. A bottom plate is slidably connected between the support plates. Second straight slots are symmetrically provided on the bottom plate. Bolts are symmetrically threadedly connected to the bottom plate corresponding to the first straight slots. Tightening nuts are threadedly connected to the bolts.

[0005] Further, a control rotation block is fixedly installed on one side of the filter body away from the inlet and outlet. The control rotation block is a regular polygon.

[0006] Further, a gap is provided between the sealing ring and the inlet and outlet of the filter body.

[0007] Furthermore, a side of the arc-shaped plate close to the filter body is rotatably connected to a plurality of rollers, and the rollers are in contact with the inner wall of the groove.

[0008] Furthermore, the arc-shaped plate is made of low-carbon steel material.

[0009] Beneficial effects of the utility model:

[0010] The utility model designs a corresponding auxiliary structure on the traditional filter body, which can facilitate workers to install in a small space, and at the same time can provide a certain stability for the filter body, reduce the pressure on the oil outlet of the machine itself, and protect the stable operation of the overall structure; in addition, the design of the sealing ring can also receive a part of the oil leaked when the filter body is disassembled, so as to better protect the environment inside the machine.

[0016] 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.

[0017] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "equipped with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] Please refer to all the specification drawings:

[0019] A filter housing includes a filter body 1, a sealing ring 2 is fixedly installed at the inlet and outlet positions of the filter body 1, a thread 3 is provided inside the sealing ring 2, and an auxiliary installation component is provided on the filter body 1;

[0021] From the above description, it can be seen that when installing the machine, it is necessary to fix it inside the machine through the second straight slot 9 of the bottom plate 8 according to the position of the oil outlet pipe in advance by corresponding parts, and then continuously adjust the position of the first straight slot 7 through the bolts 10 and the fastening nuts 11 so that the height of the arc plate 5 meets the requirements for installing the filter body 1. Through the thread 3, the filter body 1 can be quickly installed on the oil outlet pipe of the machine; specifically, when disassembling, first rotate the filter body 1 to loosen it. With the assistance of the arc plate 5, the operation can be conveniently completed. The oil is collected through the sealing ring 2 to prevent excessive leakage. After it is completely loosened, directly pull out the filter body 1 from the arc plate 5. When installing, press the groove 4 on the corresponding filter body 1 against the arc plate 5 and then rotate through the thread 3 so that the installation of the filter body 1 can be quickly completed.
