[0029] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0030] This application proposes a low-cost waterproof shell structure; please refer to [link / reference]. Figure 2 The device includes a cover 100 and fasteners 200. The cover 100 includes a first housing 101, a second housing 102, and a sealing strip 300. The fasteners 200 are used to lock the first housing 101 and the second housing 102 together. The sealing strip 300 is disposed in the gap between the first housing 101 and the second housing 102, and serves to seal, waterproof, and dustproof the first housing 101 and the second housing 102. The first housing 101 and the second housing 102 are respectively provided with matching and aligned through mounting holes, and the inner walls of the mounting holes are provided with internal threads. The fasteners 200 include a nut 201 and a screw 202. The nut 201 is disposed at one end of the screw 202, and the outer surface of the screw 202 is provided with external threads. The external thread structure of the screw 202 is screwed into the internal thread structure of the mounting hole, and the nut 201 abuts against the edge of the mounting hole of the first housing 101, thereby completing the fixation of the first housing 101 and the second housing 102. Moreover, the sealing strip 300 is disposed between the first housing 101 and the second housing 102 to enhance the sealing between them.

[0031] Please see Figure 1 In existing technologies, the sealing and waterproofing process involves stacking a first housing 100', a sealing strip 300', and a second housing 101' sequentially. Matching and through mounting holes are formed on each of the first housing 100', sealing strip 300', and second housing 101'. One end of a screw 200' passes from above the first housing 101' into the lower part of the second housing 102', and then passes sequentially through the first housing 101', sealing strip 300', and second housing 102'. A nut 400' screws the screw 200' screw into the lower part of the second housing 102', thus locking the first housing 101', sealing strip 300', and second housing 102' together to achieve a sealing and waterproofing function. Compared to existing technologies, the structure of this application reduces the amount of material used for the nut 400', lowers production costs, and significantly reduces production expenses in mass production. Furthermore, the fastener of this invention does not pass through the sealing strip, nor does it compress the sealing strip. Therefore, when workers are fastening and fixing the first and second housings, there is no need to consider the compression of the sealing strip. They only need to reliably lock the first and second housings with the fasteners to improve production efficiency.

[0032] Please refer to it again. Figure 2 The low-cost waterproof housing structure also includes a gasket 400, which is annular and fitted onto the screw 202. One side of the gasket 400 abuts against the first housing 101, and the opposite side abuts against the nut 201. Due to inaccuracies in the connecting parts or other reasons, it is necessary to adjust the gap between the nut 201 and the parts. Adjusting the dimensions using screws and gaskets 400 of different thicknesses and materials ensures the normal operation of the machine or equipment and reduces malfunctions and safety accidents caused by poor connections. The gasket 400 is either a rubber washer or a metal sheet. Rubber washers and metal sheets reduce vibrations generated by equipment operation, reducing noise and vibration, thereby extending the equipment's service life. The screw and the rubber gasket 400 form a seal between the bolt and the surface of the parts, preventing moisture and other liquids from seeping between the first housing 101 and the second housing 102, thus preventing corrosion or damage to the first housing 101 and the second housing 102 due to moisture.

[0033] Furthermore, the fastener 200 is a stainless steel screw. Stainless steel screws are made of stainless steel, which has high strength, strong locking reliability, and avoids rusting that would reduce sealing performance. Preferably, the nut 201 has a regular hexagonal cross-section along its length, allowing the fastener 200 to be tightened or loosened using a hexagonal tool.

[0034] Please see Figure 2 and 3The second housing 102 includes a mounting plate 103, a connecting plate 104, and an isolation plate 105, with the mounting plate 103 and isolation plate 105 arranged parallel to each other. The connecting plate 104 is positioned above the mounting plate 103 and isolation plate 105, and the mounting plate 103 is connected to the isolation plate 105 via the connecting plate 104. The mounting plate 103 has mounting holes with external threads for screwing into fasteners 200. The fasteners 200 are relatively shorter than those in the prior art, do not penetrate the isolation plate 105, and do not encroach on the space within the isolation plate 105. Under the same external dimensions, the internal space of the product is increased, thus accommodating more product structures. More specifically, a sealing strip 300 is positioned above the connecting plate 104. One side of the sealing strip 300 is tightly connected to the connecting plate 104, and the opposite side is tightly connected to the inner wall of the first housing 101.

[0035] Furthermore, a waterproof adhesive layer is provided between the sealing strip 300 and the first housing 101, ensuring a tight connection between them. Similarly, a waterproof adhesive layer is provided between the sealing strip 300 and the second housing 102. This layer has strong adhesion, firmly fixing the sealing strip 300 to both the first and second housings 101, thus enhancing their sealing performance. Furthermore, the nut 201 has a rotating part at the end furthest from the screw 202. This rotating part facilitates tightening or loosening of the fastener 200 using tools, improving work efficiency.

[0036] Furthermore, the front shape of the rotating part is one of a straight groove, a cross groove, a four-corner groove, or a hexagonal groove. This application proposes four common designs that allow for disassembly or locking with four different tools, enhancing versatility.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
