[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A sliding cover type photovoltaic module junction box comprises a shell 1, a cover plate 2 is inserted into the top of the shell 1, a non-slip pad 3 is connected to the upper side of the cover plate 2, and a positioning mechanism 4 is arranged inside the shell 1; the positioning mechanism 4 comprises a thickening block 401, the thickening block 401 is fixed to the inner side of the shell 1, a through groove 402 is opened at the top of the thickening block 401, a through block 403 is inserted into the through groove 402, and the through block 403 is fixed at one end of the through groove 402 to limit the block 404, the bottom end of the limit block 404 is connected to a connecting rod 406, the outer sleeve of the connecting rod 406 is provided with a first spring 405, a positioning groove 407 is provided inside the cover plate 2 at a position corresponding to the position of the penetration block 403, a sliding structure is formed between the penetration block 403 and the thickening block 401, the penetration block 403 is tightly fitted with the cover plate 2, a slide rail 5 is provided on the upper inner part of the shell 1, a slider 6 is fixed to the outer wall of the cover plate 2 at a position corresponding to the slide rail 5, and a resistance roller 7 is rotatably connected to one side of the slider 6.

[0028] By adopting the above technical scheme, first, the cover plate 2 slides into the slide rail 5 of the shell 1 through the slider 6 to form a sliding switch to improve the convenience of disassembly and assembly, and the friction roller 7 improves the smoothness of the switch closing process. When the cover plate 2 and the shell 1 are closed, the penetration block 403 loses the friction and aligns with the positioning groove 407. The first spring 405 elastically contracts and slides along the connecting rod 406 to avoid bending. The connecting rod 406 penetrates the bottom end of the thickened block 401 to avoid mutual friction and facilitate the limit block 404 to slide stably along the penetration groove 402. The limit block 404 enters the positioning groove 407 to limit the cover plate 2 to avoid loosening and detachment after sliding. The bottom end of the positioning groove 407 of the cover plate 2 corresponds to the position of the penetration block 403 and a reserved groove with a size that meets the requirements is opened to further improve the stability of the cover plate 2 after connection.

[0029] Specifically, Figure 1 and Figure 5 As shown, a slot 8 is provided inside the penetration block 403, and a limiting mechanism 9 is provided inside the slot 8. The limiting mechanism 9 includes a locking plate 901, an outer wall of the locking plate 901 that passes through the slot 8, and an end of the locking plate 901 that passes through the cover plate 2 is connected to a second spring 902. The limiting mechanism 9 also includes a placement groove 903, and the placement groove 903 is provided at the top of the locking plate 901. A third spring 904 is embedded in the placement groove 903, and a connecting plate 905 is fixed to one end of the third spring 904 that passes through the placement groove 903. A resistance block 906 is embedded on the top of the connecting plate 905. The connecting plate 905 forms an elastic structure with the locking plate 901 through the third spring 904, and the locking plate 901 forms a locking structure with the penetration block 403 through the slot 8.

[0030] By adopting the above technical solution, the second spring 902 elastically pushes the locking plate 901 to insert into the locking slot 8, and further limits the penetration block 403 to prevent loosening. When the resistance block 906 is misaligned with the penetration block 403, the third spring 904 pushes the connecting plate 905 to allow the resistance block 906 to pass through the placement slot 903 and be limited by the penetration block 403, so that the locking plate 901 is limited to avoid loosening, thereby improving the connection stability between the shell 1 and the cover plate 2.

[0031] Working principle: the cover plate 2 slides into the slide rail 5 of the housing 1 through the slider 6 to form a sliding cover connection. The slider 6 is L-shaped and can match the slide rail 5 to improve the sealing performance. The sliding is smoothed by the abutting roller 7. The first spring 405 elastically contracts along the connecting rod 406, so that the limit block 404 slides along the penetration groove 402, and the penetration block 403 penetrates the thickened block 401 and penetrates the positioning groove 407 of the cover plate 2. The convex block at one end of the cover plate 2 is inserted into the groove at the corresponding position of the housing 1 to avoid To prevent the cover plate 2 from slipping, the anti-skid pad 3 is used to prevent hand slipping during manual disassembly and assembly. Subsequently, under the elastic push of the second spring 902, the locking plate 901 is inserted into the slot 8 to position the protruding block 403. At the same time, the third spring 904 elastically pushes the connecting plate 905 to pass through the mounting slot 903, so that the resistance block 906 is in contact with one end of the protruding block 403 to improve the stability of the limit. When disassembling and assembling, the resistance block 906 is pressed to compress the third spring 904, which facilitates pushing the locking plate 901 out of the slot 8.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
