The appearance of the buckle body 2 of the belt assembly of this embodiment is different from that of the other embodiments in that the outer surface of the buckle body 2 of this embodiment is connected to form an integral surface, and any other decoration can be made, and the surface of the decoration panel 28 can be used as a pattern printing plate, a relief plate, or the like. The invention provides a plurality of styles for users to select, and the users can select the styles according to their own hobbies.

This belt dress convenient to use. In the process of pulling the free end of the belt body 1, the first latch 11 extrudes the second latch 31, so that the sliding hook 3 is forced to reversely slide, the sliding hook 3 is forced to retract into the buckle body 2, the sliding hook 3 resets after being adjusted to a proper position, the second latch 31 is enabled to be meshed with the first latch 11, and automatic adjustment is realized. When the belt needs to be pulled out, the driving assembly 4 is operated to push the belt body 1 to force the sliding hook 3 to retract into the buckle body 2, so that the sliding hook 3 overcomes the elastic reverse sliding, the second latch 31 is separated from the first latch 11, and the belt is pulled out. The belt device not only meets the requirement of people on randomly and conveniently adjusting the tightness of the belt, but also has simple structure, light weight and thin overall thickness; the inner side surface of the buckle body 2 of the belt device is flat, the inner side surface of the buckle body 2 is flush with the inner side surface of the belt body 1 completely, a human body can be more closely fitted, the belly can not be hit by a sharp structure, and the use comfort is extremely high.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
