DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.
[0026] like Figure 1-Figure 4 As shown, a sealed door structure of a box includes a first frame 3 fixedly connected to an opening 2 of a box panel 1, a second frame 4 hinged to the outer side of the box panel 1 at one side by a hinge, and a lock 5 arranged between the first frame 3 and the second frame 4.
[0027] The first frame 3 is fixedly connected to the inner side wall of the box panel 1 and extends in a ring shape around the opening. The end of the first frame 3 away from the box panel 1 has a first folded edge 6 folded toward the center. The second frame 4 is set as a ring structure matched with the first frame 3, and the outer edge of the second frame 4 has a second folded edge 7 folded toward the center in an L-shaped structure. The second folded edge 7 is rotated to abut against the surface of the first folded edge 6. At this time, the outer wall of the second frame 4 away from the inside of the box is in the same plane as the outer side wall of the box panel 1. A first sealing gasket ring 8 is provided between the first folded edge 6 and the second folded edge 7, and the first sealing gasket ring 8 is fixedly connected to the surface of the first folded edge 6.
[0028] The lock element 5 includes a lock core 9 installed on the second frame 4 and a lock tongue 10 connected to the lock core 9. When the lock core 9 is in a locked state, the lock tongue 10 is engaged with a side of the first folded edge 6 away from the second folded edge 7.
[0029] An observation window 11 is provided inside the second frame body 4. To facilitate installation of the observation window 11, a fixing ring 12 extending circumferentially around the second frame body 4 is fixedly connected to one side close to the inside of the box body, and a pressing ring 13 matching the shape of the fixing ring 12 is connected to the side of the fixing ring 12 away from the second frame body 4 by bolts, and the outer edge of the observation window 11 is pressed between the first frame body 3 and the pressing ring 13. Through the cooperation of the fixing ring 12 and the pressing ring 13, the installation of the observation window 11 is facilitated, and the structure is simple.
[0030] In order to improve the sealing performance at the observation window 11, a second sealing gasket ring 14 is provided between the pressure ring 13 and the outer edge of the observation window 11 and between the first frame body 3 and the outer edge of the observation window 11. By providing the second sealing gasket ring 14 between the pressure ring 13 and the outer edge of the observation window 11 and between the first frame body 3 and the outer edge of the observation window 11, the sealing performance at the opening 2 is improved. In addition, the outer edge of the pressure ring 13 has a third folded edge 15 folded toward the second frame body 4. By providing the third folded edge 15, the situation of external dust entering the gap of the observation window 11 can be reduced, and the sealing performance is further improved.
[0031] The implementation principle of the utility model is:
[0032] By arranging the first frame 3, the second frame 4 and the lock 5 in coordination, the sealing of the opening 2 of the box panel 1 can be achieved, and the structure is simple. The first frame 3 and the second frame 4 are both plate structures, but are well sealed by cooperating with the first folded edge 6, the second folded edge 7 and the first sealing gasket ring 8.
[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
