[0022] As a technical optimization of this utility model, a lock 6 is connected to one side of the hollow sealed door body 1, and a decorative painting 7 is pasted on one side of the hollow sealed door body 1.
[0023] In this embodiment, the use of lock 6 and decorative painting 7 not only facilitates locking of the hollow sealed door body 1, but also enhances the aesthetics of the hollow sealed door body 1.
[0024] As a technical optimization of this utility model, two mounting grooves 11 are provided on the inner side wall of the door frame 2, and a set of positioning holes 12 are provided on the inner side wall of each mounting groove 11.
[0025] In this embodiment, the base plate 301 can be conveniently positioned with respect to the mounting groove 11 using the mounting groove 11 and the positioning hole 12.
[0026] As a technical optimization of this utility model, each hinge body 308 has a set of connecting holes 8 on one side and a set of mounting screws 9 on one side.
[0027] In this embodiment, the hollow sealing door body 1 and the hinge body 308 can be easily installed using the connecting hole 8 and the mounting screw 9.
[0028] As a technical optimization of this utility model, a set of insertion holes 5 are provided on one side of the base plate 301, and a set of fastening screws 10 are provided on one side of each base plate 301. Each fastening screw 10 is adapted to the insertion hole 5 and the positioning hole 12, and each mounting groove 11 is adapted to the base plate 301.
[0029] In this embodiment, the base plate 301 can be easily installed on the inner wall of the mounting groove 11 using the insertion hole 5 and the fastening screw 10.

[0032] The working principle and usage process of this utility model are as follows: First, the door frame 2 is fixed to the wall, and the base plate 301 is placed inside the mounting groove 11. The thickness of the base plate 301 is greater than the thickness of the mounting groove 11, which prevents the screw 305 from contacting the door frame 2. Then, the base plate 301 is installed to the door frame 2 using the fastening screw 10, the insertion hole 5, and the positioning hole 12. The hollow sealed door body 1 is installed to the hinge body 308 using the mounting screw 9 and the connecting hole 8. When the hollow sealed door body 1 rubs against the ground, the screw 305 is rotated. Simultaneously, the rotation of the screw 305 engages with its threaded connection to the internal thread fixing seat 306 and the internal thread hole seat 304. The sliding rod 302 is slidably connected to the mounting seat 303, which can drive the hinge body 308 and the hollow sealed door body 1 to rise and fall. Both quick-installation components 3 need to be adjusted. This is the complete usage process of this utility model.
