[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a filter housing, including a housing body 1 and a bottom plate 2 located below the housing body 1. The top of the bottom plate 2 is fixedly connected with insertion strips 4 symmetrically distributed front and back. Both the front and back sides of the housing body 1 are fixedly connected with insertion sleeves 5. The upper end of the insertion strip 4 movably penetrates through the insertion sleeve 5. A bolt 6 is threadedly inserted into the insertion sleeve 5, and the threaded end of the bolt 6 abuts against the insertion strip 4. By adjusting the position of the insertion strip 4 inside the insertion sleeve 5 and then locking it by rotating the bolt 6, the distance between the housing body 1 and the bottom plate 2 changes, thereby adjusting the height of the housing body 1 so that the height of the housing body 1 is suitable for the actual installation environment.

[0022] A plurality of stacked support plates 3 are detachably installed between the bottom plate 2 and the housing body 1. The housing body 1 contacts the uppermost support plate 3, and the bottom plate 2 contacts the lowermost support plate 3; The support plate 3 can be made of polyethylene material, which has characteristics such as being light and corrosion-resistant.

[0023] Arranging a plurality of stacked support plates 3 on the bottom plate 2 can play a role in supporting and height-adjusting the housing body 1. While adjusting the height of the housing body 1, the stability of the housing body 1 is improved; The operation of installing the support plate 3 is relatively simple, and the height of the housing body 1 can be flexibly adjusted to meet the requirements of different installation environments.

[0024] A limiting hole 101 is opened at the bottom of the housing body 1, an insertion hole 301 is opened on each support plate 3, and a pin 7 is fixedly connected to the bottom plate 2. The number of the limiting holes 101, the insertion holes 301, and the pins 7 is 4 each, and they are all rectangularly distributed; During installation, the upper end of the pin 7 passes through a plurality of limiting holes 101 and is inserted into the insertion hole 301 inside, so that a plurality of support plates 3 are stacked on the bottom plate 2, and the pin 7 achieves the purpose of positioning the support plate 3.

[0025] When it is necessary to adjust the vertical height of the housing body 1, the number of support plates 3 stacked on the bottom plate 2 can be increased or decreased, and then the pin 7 is sequentially passed through the insertion holes 301 of each support plate 3, so that the upper end of the pin 7 is inserted into the limiting hole 101. The housing body 1 is arranged on the uppermost support plate 3; At the same time, the insertion strip 4 penetrates through the insertion sleeve 5, and by rotating the bolt 6, the threaded end of the bolt 6 abuts against the insertion strip 4 to achieve the locking purpose; At this time, the installation height of the housing body 1 is adapted to the actual installation environment.

[0026] The insertion hole 301 and the limiting hole 101 are circular holes, and the pin 7 is a cylindrical pin structure. The cylindrical pin can be accurately inserted into the circular hole, providing good positioning and alignment accuracy; This is particularly important in assembly; The structural design of the circular hole and the cylindrical pin is simple, easy to manufacture and process; This reduces the production cost and improves the manufacturing efficiency.

[0027] Positioning holes 201 are provided at the four corners of the bottom of the bottom plate 2, so that fasteners can be arranged in the positioning holes 201 to fixedly install the bottom plate 2 on the frame.
