Air filter

Technical Field

The utility model relates to an air filter, in particular to an air filter with a compact structure.

Background

The air filter is mainly used for filtering air in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms and various precision operation rooms. The engine needs to suck a large amount of air in the working process, and if the air is not filtered, dust suspended in the air is sucked into the air cylinder, so that the abrasion of the piston group and the air cylinder can be accelerated. Larger particles enter between the piston and the cylinder, which can cause severe "scuffing" phenomena, which are particularly severe in dry sandy working environments. The air filter is arranged in front of the carburetor or the air inlet pipe, plays a role in filtering dust and sand in air, and ensures that sufficient and clean air enters the cylinder.

Preferably, the second mounting portion is recessed from the first mounting portion. In this scheme, the setting mode of second installation department indent in first installation department can make the structure of installing support compacter, avoids the installing support too big.

Preferably, the second mounting portion is provided with an arcuate engagement surface. In this scheme, the setting of arc faying surface can let the installing support can also cooperate with circular pipe fitting to can improve the compatibility of air cleaner installation.

Preferably, a bushing is provided in the second mounting portion. In this scheme, the setting of bush can strengthen the installing support, prevents to appear torsion misleading to the problem that the installing support damaged during the assembly.

Preferably, the bushing is located in the middle of the second mounting portion. In this scheme, the mode with the bush setting in the middle part can make the fastening force when the installation balanced to avoid the installing support to damage.

Preferably, the end of the bushing is provided with a threaded connection. In this scheme, the setting of threaded connection spare is convenient to air cleaner's installation.

Preferably, the threaded connection is a fastening nut and/or a fastening bolt provided on the inner surface of the bushing. In this scheme, the selection of threaded connection spare conveniently realizes air cleaner's firm installation.

Preferably, the bushing is a length switchable bushing. In this scheme, the bush sets up to the length adjustable back, can guarantee that the installing support is when installing on different pipe fittings, and the bush can not bulge second installation department to can avoid the problem of installing support or installation department damage because of the improper installation torsion that leads to when assembling effectively.

The utility model has the following beneficial effects:

1. the air filter has simple structure and high installation stability;

2. the air filter can be suitable for being installed on pipe fittings with different shapes, and the application range of the air filter is enlarged;

3. the damage of the mounting bracket or the mounting part caused by improper assembly torque during assembly can be effectively avoided, so that the service life of the air filter is prolonged.
