Detailed Description
Embodiments of the present invention will be further described with reference to the accompanying drawings.
Example 1: in the specific embodiment 1 of the product shell of the present invention, as shown in fig. 1 and 2, 1 is a shell frame, 2 is a cover plate, 3 is a fastening bolt, 4 is a sealing gasket, 5 is a nut, 6 is a D-shaped sealing strip, 7 is a male and female stud, 8 is a one-shaped sealing strip, 9 is a flat pad, 10 is a spring pad, 11 is a frame connecting edge, 12 is an everting edge, 13 is a cover plate connecting edge, 14 is an everting edge, 15 is a cover plate body, and 16 is a frame base plate.
As shown in fig. 1, the upper end of the housing frame 1 is an open end, the frame 1 includes a frame substrate 16 located at the open end, one end of the frame substrate 16 close to the inner side is connected with a frame connecting edge 11 in a bending transition manner, and one end of the frame connecting edge 11 far away from the frame substrate 16 is provided with an eversion edge 12. The cover plate 2 comprises a cover plate body 15, one end, close to the outer side, of the cover plate body 15 is connected with a cover plate connecting edge 13 in a bending transition mode, and one end, far away from the cover plate body 15, of the cover plate connecting edge 13 is provided with an inward turning edge 14.
The cover plate body 15 is provided with the "D" shaped sealing strip 6, the frame base 16 is provided with the "one" shaped sealing strip 8, and when the cover plate 2 is assembled on the housing frame 1 from the up-down direction shown in fig. 1, the "D" shaped sealing strip 6 seals the gap between the cover plate body 15 and the valgus edge 12, and the "one" shaped sealing strip 8 seals the gap between the frame base 16 and the valgus edge 14. In this embodiment, set gradually "D" type sealing strip 6 and "one" type sealing strip 8 along the direction of assembly, can be with the whole sealings in gap between casing frame 1 and the apron 2, and "D" type sealing strip 6 and "one" type sealing strip 8 set gradually along the direction of packing into, can guarantee that "D" type sealing strip 6 and "one" type sealing strip 8 are all closely installed.
The frame connecting edge 13 and the cover plate connecting edge 11 are arranged in parallel, the cover plate connecting edge 11 is located on the outer side of the frame connecting edge 13, through holes penetrating in the left-right direction shown in fig. 1 are formed in the frame connecting edge 13 and the cover plate connecting edge 11, the female and male studs 7 are arranged between the frame connecting edge 13 and the cover plate connecting edge 11, threaded blind holes are formed in the left ends of the female and male studs 7, the right ends of the female and male studs 7 are provided with external thread sections, when the frame connecting edge 11 is used, the external thread sections of the right ends of the female and male studs 7 penetrate through the through holes in the frame connecting edge 13 and are fixed on the frame connecting edge 11 through nuts 5, flat pads 9 are sleeved on two sides of the female and male studs 7 located on the frame connecting edge 11, and elastic pads 10 are compressed between the flat pads 9 and the nuts 5 on the right side of the frame connecting edge 11. The right end of the male and female studs 7 can be sealingly fitted on the frame connecting edge 11 by mounting the flat pads 8 and the spring pads 9.
After the male and female studs 7 are fixedly mounted on the frame connecting edge 11, the fastening bolts 3 are screwed into the threaded blind holes after passing through the through holes on the cover plate connecting edge 13, and the cover plate connecting edge 13 and the frame connecting edge 11 are fixed together. A gasket 4 is installed between the outside of the cover plate connecting edge 2 and the bolt head of the fastening bolt 3. In this embodiment, the sealing pad 4 is a silicone rubber sealing pad, and in other embodiments, other materials may be used for the sealing pad.
According to the product shell, through the double sealing effect of the one-shaped sealing strip 8 and the D-shaped sealing strip 6, external water and dust cannot enter the inner side of the frame from the outer side of the cover plate 2 through a gap between the shell frame and the cover plate, and the protection level is increased. Meanwhile, due to the fact that the D-shaped sealing strip 6 is arranged, the sealing surface of the pressed D-shaped sealing strip 6 is enlarged, the area of the sealing fit part between the cover plate 2 and the frame 1 is enlarged, and the sealing effect is further enhanced.
When the male stud 7 is not arranged on the product shell, when the sealing gasket 4 is subjected to vibration or other external force or weathering sealing failure or the sealing effect is weakened, external water can enter the external thread of the fastening bolt 3, pass through a gap between the external thread and a through hole on the connecting side of the cover plate, and then enter the frame along the external thread. After the female and male studs 7 are arranged, even if the sealing gasket 4 fails in sealing, external water enters the screw thread of the fastening bolt and passes through the gap between the screw thread and the through hole at the connecting edge of the cover plate, but the external water finally flows into the screw thread blind holes of the female and male studs 7 and does not continue to flow into the frame. Even if water on the fastening bolt threads flows out from the left end face of the male and female studs 7, the "D" type sealing strip 6 can further block external water. According to the product shell, through the dual functions of the sealing gasket 4 and the male stud 7, external water and dust cannot enter the frame through the threads of the fastening bolts, so that a good sealing effect is achieved, and the product has good waterproof and dustproof effects. The product shell can realize that the protection grade of the outdoor product reaches the standard of IP55, and can effectively solve the sealing problem of the outdoor product.
In this embodiment, the male and female studs are connectors, and in this embodiment, the connectors are secured to the frame connection edges by external threaded segments and nuts. In other embodiments, the attachment to the frame attachment edge may be by other means, such as direct welding or adhesive bonding, etc. In other embodiments, the connector may be other structures with blind threaded holes. In this embodiment, the end of the connecting piece that is pressed against the connecting edge of the cover plate is a pressing end, and the threaded blind hole is disposed at the pressing end of the connecting piece.
In this embodiment, the "D" type sealing strip is the first sealing strip, and the "one" type sealing strip is the second sealing strip.
In this embodiment, the gasket, the fastening bolt, the male and female studs, the flat pad, the spring pad, and the nut constitute a connection assembly.
In this embodiment, the frame connecting edge is an inner connecting edge, and the cover connecting edge is an outer connecting edge.
Example 2: in the embodiment 2 of the product housing of the present invention, as shown in fig. 3, the difference from embodiment 1 is that in this embodiment, a first "D" type sealing strip 6 is pressed between the everting edge of the frame and the cover plate body, and a second "D" type sealing strip 17 is pressed between the everting edge of the cover plate and the base plate of the frame.
Example 3: as shown in fig. 4, embodiment 3 of the product housing according to the present invention is different from embodiment 1 and embodiment 2 in that in this embodiment, the cover plate connecting edge 18 is an inner connecting edge, an outer edge is provided on the inner connecting edge, the frame connecting edge 19 is an outer connecting edge, an inner edge is provided on the outer connecting edge, and sealing strips are pressed between the inner edge and the cover plate and between the outer edge and the housing frame. Wherein 20 is a connection assembly, the structure of which is the same as that of the connection assemblies in embodiment 1 and embodiment 2.
In other embodiments, both the first seal and the second seal may be "one" seals or may be other forms of seals, such as "P" seals.
In a specific embodiment of the outdoor product of the present invention, the outdoor product includes a product housing, and the structure of the product housing is identical to that of the above embodiment, and the details thereof are not described herein.
