[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 like Figure 1-5 As shown, this is the first embodiment of the present invention, which provides a data acquisition box with waterproof and dustproof functions, including... The box unit 100 includes a cover 110, a cover 120 that is hinged to the front of the cover 110, a sealing gasket 130 that is fixedly connected to the surface of the cover 120, a connecting assembly 140 disposed between the cover 120 and the cover 110, and a connection port 150 opened at the bottom of the inner cavity of the cover 110. The sealing assembly 200 includes a limiting frame 210, a blocking plate 220 movably connected to the inner cavity of the limiting frame 210 and used to block the connection port 150, and a sealing strip 230 fixedly connected to the top of the blocking plate 220 and in contact with the cover 110. The heat dissipation assembly 300 includes a connecting box 310, a heat dissipation fan 320 disposed at the upper and lower ends of one side of the inner cavity of the connecting box 310, and a second breathable and waterproof membrane 330 movably connected to the other side of the inner cavity of the connecting box 310.

[0018] like Figure 1-5As shown, in the housing unit 100, the cover 120 is movably connected to the cover 110 via a hinge, and a sealing gasket 130 is fixedly connected to the surface of the cover 120. When the cover 120 is closed, the side of the sealing gasket 130 away from the cover 120 contacts the inner wall of the cover 110, forming a good seal and effectively preventing moisture and dust from entering the housing. In the sealing assembly 200, the top of the limiting frame 210 is fixedly connected to the bottom of the cover 110, and the blocking plate 220 is movably connected to the inner cavity of the limiting frame 210 to block the connection port 150. The sealing strip 230 fixedly connected to the top of the blocking plate 220 is... The cover 110 contacts the connection port 150, further enhancing the sealing performance and preventing moisture and dust from entering through the connection port 150. The operation of the cooling fan 320 accelerates the airflow inside the box, dissipating the heat generated inside in a timely manner, effectively reducing the operating temperature inside the box, and ensuring the normal operation of the internal circuit boards and components. During the heat dissipation process, the second breathable waterproof membrane 330 can intercept external moisture. While ensuring ventilation and heat dissipation, it effectively blocks the entry of moisture and dust, achieving all-round waterproof and dustproof protection, enabling the equipment to work stably in various harsh environments and extending its service life.

[0019] Example 2 Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0020] In this embodiment, the top of the limiting frame 210 is fixedly connected to the bottom of the cover 110, and the connecting box 310 is connected to the cover 110.

[0021] The front of the cover 120 and one side of the end plate 220 are provided with grooves. A sealing sleeve is fixedly connected to the inner cavity of the connection port 150, and the inner wall of the sealing sleeve is in contact with the connection line.

[0022] A ventilation slot 112 is provided on one side of the cover 110, and a first breathable and waterproof membrane 113 is fixedly connected to the inner cavity of the ventilation slot 112.

[0023] Mounting plates 111 are fixedly connected to the upper and lower ends of the back of the cover 110, and mounting holes are provided on one side of the mounting plates 111.

[0024] like Figure 1-3As shown, the top of the limiting bracket 210 is fixedly connected to the bottom of the cover 110, providing a stable support base for the blocking plate 220. This ensures that the blocking plate 220 can accurately block and seal the connection port 150 during operation. This stable connection structure enhances the reliability of the sealing assembly 200 and effectively prevents moisture and dust from entering the box from the connection port 150. The connection between the connecting box 310 and the cover 110 allows an air circulation channel to be formed between the connecting box 310 and the cover 110 when the cooling fan 320 is running, accelerating the dissipation of internal heat. The sealing sleeve fixedly connected to the inner cavity of the connection port 150 has its inner wall in close contact with the connecting wire, further enhancing the waterproof and dustproof protection at the connection port 150. In terms of performance, when the connecting cable is connected to the inside of the box through the connecting port 150, the sealing sleeve can effectively prevent moisture and dust from entering the box along the connecting cable. The ventilation slot 112 provides a channel for air to enter the cover 110, ensuring the air circulation required for heat dissipation. The first breathable and waterproof membrane 113 can prevent moisture and dust from entering. While ensuring heat dissipation, it can effectively protect the internal components and improve the adaptability of the equipment in harsh environments. The mounting plate 111 fixedly connected to the upper and lower ends of the back of the cover 110 and the mounting hole opened on one side of the mounting plate 111 provide users with a simple and quick installation method. Users can use appropriate screws through the mounting holes to firmly install the equipment in the required position according to actual needs.

[0025] Example 3 Reference Figure 1 , 2 4 and 5 are the third embodiment of this utility model, which is based on the first two embodiments.

[0026] In this embodiment, the connecting assembly 140 includes a fixing plate 141, a bolt 142 movably connected to the front of the fixing plate 141, and a connecting cylinder 143 fixedly connected to both sides of the cover 110.

[0027] There are two fixing plates 141, which are fixedly connected to the two sides of the front of the cover 120 respectively. One end of the bolt 142 passes through the fixing plate 141 and extends into the inner cavity of the connecting cylinder 143, and is threadedly connected to the inner cavity of the connecting cylinder 143. The sealing gasket 130 is in contact with the inner wall of the cover 110 on the side away from the cover 120.

[0028] A first magnet 311 is fixedly connected to one side of the inner cavity of the connecting box 310, and a second magnet 331 is fixedly connected to one side of the second breathable and waterproof membrane 330. The side of the second magnet 331 away from the second breathable and waterproof membrane 330 is in contact with the first magnet 311, and the first magnet 311 and the second magnet 331 are magnetically connected.

[0029] like Figure 1 , 2As shown in Figures 4 and 5, two fixing plates 141 are fixedly connected to both sides of the front of the cover 120. Bolts 142 pass through the fixing plates 141 and are threadedly connected to the inner cavity of the connecting cylinder 143. This multi-point connection method makes the connection between the cover 120 and the housing 110 more secure. When it is necessary to connect the cover 120 and the housing 110, the fixing plates 141 on the cover 120 are aligned with the connecting cylinders 143 on both sides of the housing 110. Then, one end of the bolt 142 is passed through the hole on the fixing plate 141 and screwed into the inner cavity of the connecting cylinder 143. As the bolt 142 is screwed in, the threads of the bolt 142 and the inner cavity of the connecting cylinder 143 gradually engage, generating tension and pulling the fixing plates 141 closer to the connecting cylinder 143. When the cover 120 and the housing 110 are tightly fitted together, the sealing gasket 130 is compressed between them and undergoes elastic deformation, filling the tiny gap between the cover 120 and the housing 110 to form a reliable seal and prevent moisture and dust from entering. The second breathable and waterproof membrane 330 is magnetically connected to the first magnet 311 on one side of the inner cavity of the connecting box 310 via the second magnet 331. This connection method does not require complicated tools or operating procedures. When the second breathable and waterproof membrane 330 is damaged, aged, or needs cleaning, the user can easily remove the second breathable and waterproof membrane 330 from the connecting box 310 and then install a new second breathable and waterproof membrane 330, which greatly shortens the maintenance time, reduces the maintenance cost, and improves the maintainability of the equipment.

[0030] In use, first, open the cover 120 and insert the connecting cable of the sensor or device to be connected into the data acquisition box through the connection port 150. During insertion, move the blocking plate 220 to allow the connecting cable to pass smoothly, while ensuring that the sealing sleeve is in close contact with the connecting cable to provide waterproof and dustproof protection. The unused connection port 150 will be further sealed by the blocking plate 220, and together with the sealing strip 230, a good seal will be formed to prevent moisture and dust from entering through the connection port 150. Then, close the cover 120, allowing the fixing plate 141 to move to the front of the connecting cylinder 143. Tighten the bolt 142, one end of which extends into the inner cavity of the connecting cylinder 143, to ensure a tight connection between the cover 120 and the housing 110. This ensures that the sealing gasket 130 is in full contact with the inner wall of the housing 110, thereby improving the sealing effect at the connection and effectively preventing moisture and dust from entering through the gap between the cover 120 and the housing 110. When the equipment is operating, heat dissipation... When fan 320 operates, it draws air out from one side of the inner cavity of connection box 310, creating a negative pressure inside the cavity. External air enters the housing 110 through ventilation slot 112 and the first breathable waterproof membrane 113, and then exits from the other side of connection box 310 through cooling fan 320, forming an air circulation that carries away the heat generated inside the data acquisition box, achieving the purpose of heat dissipation. When external air enters the housing 110 through ventilation slot 112, the first breathable waterproof membrane 113 can prevent the entry of moisture and dust. Connection box 310 is connected to housing 110, and air flows between connection box 310 and housing 110 under the action of cooling fan 320. The second breathable waterproof membrane 330 further prevents moisture and dust, ensuring heat dissipation while achieving waterproof and dustproof protection. This effectively prevents the entry of moisture and dust while ensuring ventilation and heat dissipation, achieving all-round waterproof and dustproof protection, enabling the equipment to work stably in various harsh environments and extending its service life.
