Description

Technical Field

[0001] The utility model relates to the technical field of filter installation, in particular to an air filter with stable installation. Background Art

[0002] The importance of air filters in pneumatic machinery and internal combustion machinery is self-evident. Its main function is to protect the equipment from damage to the engine and mechanical parts caused by impurities in the air. In traditional designs, the filter element and the housing constitute the core of the filter. The filter element is responsible for filtering particles in the air, while the housing provides the necessary protection and support for the filter element.

[0003] There are some problems with the existing air filter design. In particular, during the operation of the vehicle, the filter element inside the housing will shift position, which will affect its filtering efficiency and stability. This shift causes the air to enter the engine without being fully filtered, thereby increasing the risk of mechanical wear. In order to solve this technical problem, the utility model proposes an air filter with stable installation. Summary of the invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] Embodiment 1: A stably installed air filter comprises an outer shell 1 and an air filter body 5, the outer shell 1 is fixedly installed by screws 2, a plurality of mounting mechanisms 9 are fixedly connected inside the outer shell 1, and a plurality of bases 6 are provided with grooves 7 inside, the air filter body 5 is arranged in the outer shell 1, and the four corners of the air filter body 5 are inserted into the grooves 7, a mounting plate 8 is fixedly connected inside the outer shell 1, and a mounting mechanism 9 is fixedly connected between the mounting plate 8 and the air filter body 5, the mounting mechanism 9 comprises a bracket 901, a baffle 906, a connecting plate 911 and a pair of plug posts 908, both sides of the baffle 906 are fixedly connected with fixing blocks 907, and the fixing blocks 907 are fixedly connected with the plug posts 908 inside. The bracket 901 is fixedly connected to the mounting plate 8 by bolts. The bracket 901 is composed of a horizontal plate and a vertical plate at the top of the horizontal plate. A slide 902 is fixedly connected inside the vertical plate of the bracket 901, and a slide bar 903 is slidably connected inside the slide 902. At the same time, a baffle 906 is fixedly connected to the other end of the slide bar 903. A limit ring 904 is fixedly connected to the outer wall of the left end of the slide 902. At the same time, a spring 905 is fixedly connected between the baffle 906 and the limit ring 904, and the spring 905 is sleeved on the outer wall of the slide bar 903. A pair of limit blocks 909 are fixedly connected to the bottom of the baffle 906. At the same time, a pair of slide grooves 910 are opened on the top of the mounting plate 8, and the slide grooves 910 correspond to the limit blocks 909, and the limit blocks 909 are slidably connected in the slide grooves 910. The connecting plate 911 is fixedly connected to the outer wall of the groove 7, and a pair of plug holes 912 are opened inside the connecting plate 911, and the plug holes 912 correspond to the plug posts 908, and the plug posts 908 are slidably connected inside the plug holes 912. The top of the shell 1 is fixedly connected to the air outlet pipe 3, and the bottom of the shell 1 is fixedly connected to the air inlet pipe 4, and the air outlet pipe 3 corresponds to the air inlet pipe 4 in size, and the sliding rod 903 penetrates the shell 1 and extends to the outside of the shell 1.

[0024] When using the air filter body 5, the housing 1 needs to be disassembled first, which is achieved by unscrewing the screws 2 to disassemble the top cover of the housing 1. After disassembling the housing 1, the slide bar 903 needs to be pulled outward, and the slide bar 903 is limited by the slide cylinder 902 to ensure that it will not deviate when pulled outward. At the same time, the limit ring 904 ensures that the spring 905 is completely in a compressed state. Next, the air filter body 5 is placed on the four corners of the base 6 inside the housing 1, and ensure that the four corners of the air filter body 5 are correctly aligned with the groove 7 of the housing 1 to complete the positioning. Subsequently, the slide bar 903 can be loosened, so that the compressed spring 905 rebounds and pushes the baffle 906 to move forward. When the baffle 906 moves, it is limited in the slide groove 910 by the limit block 909, so as to keep the moving direction consistent. At the same time, the movement of the baffle 906 will also drive the plug 908 to move forward and insert it into the socket 912 on the connecting plate 911. The top of the baffle 906 is stuck on the connecting plate 911 to prevent the air filter body 5 from shaking up and down, ensuring the stability of the installation. The coordination of these steps ensures that the air filter body 5 is quickly and stably fixed inside the housing 1 during installation. This not only improves the installation efficiency, but also effectively prevents the deviation and shaking of the air filter body 5. After the installation is completed, the housing 1 is sealed again, and the air enters through the air inlet pipe 4 and is discharged through the air outlet pipe 3, and is effectively filtered and purified by the air filter body 5.

[0025] Working principle: when the staff needs to use the air filter body 5, first unscrew the screw 2 to disassemble the top cover of the shell 1, pull the slide bar 903 outward, and the slide bar 903 is limited in direction by the slide tube 902 to prevent the slide bar 903 from deflecting when it is pulled outward. The limit ring 904 is used to make the spring 905 completely compressed, and then the air filter body 5 is placed on the base 6 at the four corners of the shell 1, and the four corners of the air filter body 5 are aligned with the groove 7 to achieve positioning. At this time, the slide bar 903 is released again, so that the compressed spring 905 rebounds and pushes the baffle 906 forward. When the baffle 906 moves, it is limited by the limit block 909 In the slide groove 910, ensure that the baffle 906 maintains the same direction when moving. When the baffle 906 moves forward, it will also drive the plug post 908 to move forward. At the same time, the plug post 908 will be inserted into the hole 912 on the connecting plate 911, and the baffle 906 is stuck on the top of the connecting plate 911 to prevent the air filter body 5 from shaking up and down. Through the cooperation between them, the air filter body 5 is installed quickly and stably, which greatly improves the work efficiency and effectively avoids the deviation and shaking of the air filter body 5. At this time, the outer shell 1 is sealed, and the gas enters through the intake pipe 4 and is discharged through the outlet pipe 3, and is filtered and purified by the air filter body 5.
