The product using the cover body structure of the present invention has a complete appearance, without other screws, locks, hinges, etc., and there is no gap from a normal viewing angle. The screws can also be countersunk or rear-mounted to be hidden, which greatly improves the aesthetics of the product.

[0021] Specifically, the cover plate 1 forms a sliding structure with the sealing plate 5 through the sliding rails 3 and 4 , and the shape and size of the inner wall of the sliding rail 3 matches the shape and size of one side of the sliding block 4 .

[0022] Through the above technical solution, the slide rail 3 at the bottom of the cover plate 1 can slide through the slider 4, thereby achieving the sliding effect of the cover body 1.

[0023] Specifically, the cover plate 1 forms a sealing structure with the box body 2 through the sealing plate 5 and the sealing strip 7, and the sealing strip 7 has waterproof and elastic effects.

[0024] Through the above technical solution, the sealing strip 7 is required to be waterproof and have a certain amount of compression. The sealing strip 7 is subjected to vertical force in a plane, the pressure is evenly distributed, and there is no force in any shear direction, which greatly improves the service life and sealing effect of the strip.

[0025] Specifically, the box body 2 is riveted with the rivet nut 9 through the fixed folding edge 17 to form a limiting locking structure with the fixing screw 10, and the number of the rivet nut 9 can be multiple.

[0026] The above technical solution facilitates the fixing screw 10 to interlock with the rivet nut 9 riveted on the fixed fold 17 of the box body 2 through the screw hole 18 at the bottom of the cover body 1, thereby realizing the function of limiting locking between the cover body 1 and the box body 2.

[0027] Specifically, the box body 2 forms a fixed structure through the outward-turned folded edge 13 and the engaging folded edge 14 , and the engaging folded edge 14 is formed by further folding the left and right folded edges of the outward-turned folded edge 13 backward.

[0028] The above technical solution facilitates the left and right folded edges of the outward-turned folded edge 13 to continue to be folded backward to form the engaging folded edge 14 .

[0029] Specifically, the shape and size of the sealing plate 5 are smaller than the shape and size of the outwardly turned folded edge 13 , and the shape and size of the sealing plate 5 are larger than the shape and size of the sealing strip 7 .

[0030] Through the above technical solution, the size of the sealing plate 5 is slightly smaller than the outer contour size of the outward folded edge 13 of the box body 2, but larger than the outer contour size of the sealing strip 7, ensuring that it can completely cover the sealing strip 7 and achieve a sealing effect of isolating the outside world by cooperating with the sealing strip 7.

[0031] Specifically, the cover plate 1 forms a snap-fit ​​structure through the snap-fit ​​spring 8 and the snap-fit ​​fold 14 , and the fishhook spring 12 in the snap-fit ​​spring 8 can be deformed elastically, and the number of the fishhook spring 12 is multiple.

[0032] Through the above technical solution, a suitable gap is left between the locking fold 14 and the inner sides of the left and right folds of the cover body, so that when the cover body is subjected to downward pressure, the fishhook spring 12 of the snap spring 8 can be elastically deformed, so as to be locked into the inner side of the locking fold 14 and rebound, thereby locking the locking fold 14.

[0033] Specifically, the unlocking notch 15 is located adjacent to the fishhook reed 12 of the buckle reed 8 and is located below the fishhook reed 12 .

[0034] Through the above technical solution, the unlocking notch 15 is conveniently positioned adjacent to the fishhook reed 12 of the buckle reed 8 and below the fishhook reed 12 .

[0035] Specifically, the width of the unlocking interval 16 is greater than the width of the fishhook spring 12 on one side of the buckle spring 8 .

[0036] Through the above technical solution, it is convenient for the unlocking interval 16 to be slightly larger than the buckling width of a single fishhook spring 12 on the buckle spring 8.

[0037] Specifically, the opening of the screw hole 18 is aligned with the threaded hole of the rivet nut 9 , and the shape and size of the inner wall of the screw hole 18 matches the shape and size of the inner wall of the rivet nut 9 .

[0038] Through the above technical solution, a screw hole 18 is conveniently opened on the bottom fold of the cover body, and its position is aligned with the threaded hole of the rivet nut 9, and its opening specification matches the fixing screw 10 corresponding to the rivet nut 9.

[0039] Working principle: When using the sliding unlocking sealing cover, first, before fixing, pull the sealing plate 5 down to the lower end to press against the sealing positioning plate 6, and use the inner side of the lower flange of the cover to press against the bottom end of the outer flange 13 of the box body 2. At this time, the sealing plate 5 just completely presses the sealing strip 7, aligns the screw hole 18 of the cover with the rivet nut 9 on the fixed flange 17 of the box body 2 horizontally, presses both sides of the cover, completes the buckle spring 8 and the buckle flange 14 of the box body 2, and locks the fixing screw 10 to complete the installation; To open it, you only need to loosen the bottom fixing screw 10, press the outer surface of the cover body and pull it down or push it down from the upper end of the cover body, push the fishhook spring 12 of the buckle spring 8 on the cover body into the unlocking opening 15 range, and then you can remove the cover body to complete the opening. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
