[0001] This utility model relates to the technical field of air purification equipment, and in particular to a static pressure box with a scratch-resistant structure. Background Technology

[0002] A plenum chamber is an essential component for high-efficiency air outlets, reducing dynamic pressure, increasing static pressure, stabilizing airflow, and reducing airflow vibration. It is a device that allows airflow while effectively preventing or reducing the outward propagation of sound energy. High-efficiency air outlets are ideal terminal filtration devices for Class 1000, Class 10,000, and Class 100,000 (cleanroom / dust-free) purification and air conditioning systems, and are widely used in purification and air conditioning systems in industries such as pharmaceuticals, healthcare, electronics, and chemicals.

[0003] After searching, we found that... Figure 1 The static pressure chamber shown includes four first side frames installed together. Usually, the diagonal position between the first side frames on the left and right sides needs to be placed in a corner of the wall. However, this installation position makes the corner of the wall prone to damage, and may also cause some damage to the outer shell of the static pressure chamber.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a static pressure box with a scratch-resistant structure, making it more valuable for industrial use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a static pressure box with a scratch-resistant structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The main frame includes a first side frame located on the front and right sides, a second side frame located on the left side, and a third side frame located on the rear side;

[0009] The second side frame has arc-shaped ends at the top and bottom of the rear side, which are installed together with the left side of the third side frame. Arc-shaped side plates are provided on the outer side of the arc-shaped ends.

[0010] Both sides of the arc-shaped side plate are provided with a first contact plate bent inward. A second contact plate bent inward is installed on the second side frame in front of the first contact plate on the front side. A third contact plate bent inward is installed on the third side frame to the right of the first contact plate on the right side.

[0011] As a further improvement of this utility model, a first window is provided on the top plate.

[0012] As a further improvement of this utility model, a second window is provided on the first side frame on the front side.

[0013] As a further improvement of this utility model, an integrally formed splicing plate is provided on the inner side of the first side frame, the second side frame and the third side frame near the bottom, and the four splicing plates form a fan mounting frame.

[0014] As a further improvement of this utility model, the first contact plate is respectively snapped onto the second contact plate and the third contact plate.

[0015] As a further improvement of this utility model, an elastic buffer layer is installed on the outer side of the arc side plate.

[0016] As a further improvement of this utility model, the elastic buffer layer is made of EPDM rubber.

[0017] As a further improvement of this utility model, the thickness of the elastic buffer layer is 5~10mm.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] This invention, through the structural design of the arc-shaped side plate, and the placement of the arc-shaped side plate at the corner of the wall, greatly reduces the probability of damage to the corner of the wall and the outer shell of the static pressure box.

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Existing technologies such as Figure 1 As shown, the static pressure box includes four first side frames 1 installed together with each other. A 90-degree angle is formed between the two first side frames 1 on the left and rear sides. This angle is often placed in a corner of the wall, which makes it easy for the corner of the wall to be damaged, and may also cause some damage to the outer shell of the static pressure box.

[0033] The first embodiment of this utility model:

[0034] like Figure 2The static pressure box with anti-scratch structure in this embodiment mainly includes a main frame, a top plate 2 installed on the top of the main frame, a fan mounting bracket 3 installed on the inner side of the main frame near the bottom, and a fan 4 installed on the fan mounting bracket 3.

[0035] In addition, the main frame mainly includes two first side frames 1, one second side frame 5, and a first and third side frame 6. The two first side frames 1 are located on the left and front sides respectively, the second side frame 5 is located on the left side, and the third side frame 6 is located on the rear side. The four are installed together to form the main frame. The two first side frames 1, one second side frame 5, and the first and third side frame 6 can be welded together.

[0036] and Figure 1 The difference is that, in this embodiment, the rear top and bottom of the second side frame 5 are provided with arc-shaped ends (such as those that are installed together with the left side of the third side frame 6) Figure 3 Furthermore, an arc-shaped side plate 7 is provided on the outer side of the arc-shaped end. The arc-shaped end is welded together with the left side of the third side frame 6, making the middle part hollow. Then, the arc-shaped side plate 7 is installed in the hollow part and then welded together.

[0037] Traditional right-angle connections are prone to frame deformation due to stress concentration, while curved ends disperse the stress at the connection (such as vibration loads when installing wind turbines) through the arc transition, improving the deformation resistance of the main frame.

[0038] The combination of the arc-shaped side plate 7 and the contact plate forms an arch-like mechanical structure, which can withstand greater external pressure (such as the squeezing during wall installation) and extend the service life of the equipment.

[0039] Furthermore, even more advanced designs could incorporate curved side panels 7 at the other four diagonal corners, thus providing scratch protection for all four corners of the main frame. Transforming right angles into smooth, rounded surfaces eliminates the risk of physical scratches at the source, making it particularly suitable for scenarios with frequent personnel contact (such as central air conditioning rooms and industrial equipment operating areas).

[0040] like Figure 4 and Figure 5 On both sides of the arc side plate 7, there are first contact plates 11 bent inward. Correspondingly, on the second side frame 5 in front of the first contact plate 11 on the front side, there is a second contact plate 12 bent inward and installed together with it. On the third side frame 6 to the right of the first contact plate 11 on the right side, there is a third contact plate 13 bent inward and installed together with it.

[0041] During the specific installation process of the arc side plate 7, the first contact plate 11 on the front side is fastened together with the second contact plate 12, and the first contact plate 11 on the right side is fastened together with the third contact plate 13, and then they are welded together in pairs.

[0042] Among them, the first contact plate 11 forms a three-dimensional superimposed protective layer with the second contact plate 12 and the third contact plate 13. The bending design makes the contact plate form an elastic buffer structure. Even if it is hit by external force, it can absorb the impact force through the deformation of the plate and reduce the damage to the equipment surface.

[0043] Furthermore, the overlapping installation between the contact plates (such as fixing the second contact plate 12 to the front first contact plate 11) further fills the gap between the arc end and the side frame, preventing fingers or tools from getting stuck in the corner gap.

[0044] The engagement method between the first contact plate 11, the second contact plate 12, and the third contact plate 13 can be a pressing and embedding method in the front-back or left-right direction, or a pressing and embedding method in the vertical direction.

[0045] In addition, the arc-shaped end, arc-shaped side plate 7 and contact plate adopt a prefabricated modular design, which can be assembled in advance in the factory. On site, only the main frame (first side plate 1, second side frame 5, third side frame 6) and arc-shaped components need to be quickly spliced ​​together, reducing on-site cutting and grinding processes and lowering construction costs.

[0046] The second embodiment of this utility model:

[0047] like Figure 2 A first window 8 is provided on the top plate 2, and a second window 9 is provided on the first side frame 1 on the front side. The first window 8 and the second window 9 are both commonly used working areas of the static pressure box, so windows need to be designed to match the corresponding functional structural components. The way they are designed on the top and front sides allows for easy operation and use.

[0048] The third embodiment of this utility model:

[0049] like Figure 2 and Figure 3 One-piece molded splicing plates 10 are respectively provided on the inner side of the first side frame 1, the second side frame 5, and the third side frame 6 near the bottom. The four splicing plates 10 form the fan mounting frame 3. The four splicing plates 10 are spliced ​​together at the diagonal angles and then welded together. The one-piece molded fan mounting frame 3 can effectively reduce the welding area.

[0050] The fourth embodiment of this utility model:

[0051] An elastic buffer layer is installed on the outer side of the arc-shaped side plate 7. This elastic buffer layer can be 5-10mm thick EPDM rubber. The elastic buffer layer of EPDM rubber further enhances the impact resistance, and at the same time, the rubber layer can absorb the noise generated by the fan vibration, making it suitable for high-vibration and high-noise industrial environments (such as workshop ventilation systems).

[0052] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0053] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
