[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a carton with a transparent window of the utility model comprises a carton, the carton is composed of an upper box body 1 and a lower box body 2, an observation gap for viewing the internal situation of the carton is formed between the upper box body 1 and the lower box body 2, a fixed frame 3 is installed on the outside of the upper box body 1 and the lower box body 2, an adjustment middle frame 4 covering the observation gap is formed between the fixed frames 3, an observation port is provided on one side surface of the adjustment middle frame 4, a transparent sheet 12 is installed in the observation port, rollers are installed on the four opposite corners of the upper box body 1 and the lower box body 2, and the outer ring surface of the roller is in contact with the inner ring surface of the adjustment middle frame 4;

[0021] Among them, a plurality of box covers 8 for covering the upper opening of the carton are installed on the top surface of the upper box body.

[0022] In this embodiment, a frame-type sliding groove 9 is formed on the opposite surfaces of the fixed frame 3, and a plurality of positioning rods 11 are installed along the inner side of the outer wall of the adjusting middle frame 4, and both ends of the positioning rods 11 protrude from the adjusting middle frame 4 and are inserted into the sliding groove 9, and the positioning rods 11 are arranged away from the observation port.

[0023] In this embodiment, support plates 7 connecting the upper box body 1 and the lower box body 2 are installed on the four corners inside the upper box body 1 and the lower box body 2. The support plates 7 are arranged in an "L"-shaped structure. The support plates 7 are made of plastic material. The support plates can support the upper box body and the lower box body, thereby preventing the upper box body from falling downward.

[0024] In this embodiment, the adjusting middle frame 4 is made of rubber material, and a plurality of wires of a frame-shaped structure are installed inside the adjusting middle frame 4. The outer side surfaces of the adjusting middle frame 4 are located on both sides of the transparent sheet 12 and protrude to form a hand-held portion 6, wherein the shape of the adjusting middle frame can be positioned by the wires, and the adjusting middle frame is always in a frame-shaped state, thereby preventing the adjusting middle frame from being pulled outward.

[0025] In this embodiment, the transparent sheet 12 is a transparent film, and a shielding plate 5 is provided on the outside of the transparent sheet 12 to cover the transparent sheet 12. The upper end of the shielding plate 5 is installed on the outer surface of the adjusting middle frame 4. The shielding plate 5 is made of a black thin sheet. When not in use, the transparent sheet can be blocked by the folding part, thereby preventing external sunlight from irradiating into the interior of the carton and affecting the items inside the carton.

[0026] In this embodiment, bearings are embedded and installed on the four corners of the opposite surfaces of the upper box body 1 and the lower box body 2, and the roller shafts at both ends of the drum are installed in the inner rings of the bearings;

[0027] During the movement of the adjusting middle frame, the adjusting middle frame can rub against the roller, causing the roller to rotate. The rotating roller reduces the friction, which can better drive the rotation of the adjusting middle frame. The roller can also open the four sides of the adjusting middle frame, so that the adjusting middle frame is set in a frame-shaped structure and contacts the outer side of the carton.

[0028] When it is necessary to check the items inside the carton, there is no need to open the box cover. The baffle can be lifted so that the situation inside the carton can be clearly seen through the transparent sheet. Since the transparent sheet is installed on the adjustable middle frame, the adjustable middle frame can be lifted and moved along the outer side of the carton after holding the handle. The movement of the adjustable middle frame simultaneously drives the positioning rod and the transparent sheet to change the position of the transparent sheet, thereby increasing the observation range and providing a more complete understanding of the situation of the items inside the carton. The positioning rod can be used to position the adjustable middle frame so that the adjustable middle frame can only be rotated along the slide slot, thereby avoiding separation from the upper and lower fixed frames.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
