DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model.

[0022] The utility model provides technical scheme: as Figure 2 And Figure 3As shown, in this embodiment, a carton with a space adjusting structure comprises an outer box body 1, an adjusting assembly 5 is installed inside the outer box body 1, the adjusting assembly 5 comprises two mounting rings 501 which are slidingly inserted inside the outer box body 1, four connecting columns 502 are fixedly connected between the two mounting rings 501, the same moving ring 503 is slidingly sleeved on the four connecting columns 502, the outer wall of the moving ring 503 is attached to the inner wall of the outer box body 1, the inner box body 504 is fixedly connected inside the moving ring 503, and one positioning assembly 6 is installed between the moving ring 503 and two of the connecting columns 502.

[0023] If the individual items to be packed are large, the outer box body 1 is pulled upward, and each assembly connected thereto will be driven to move upward synchronously, the moving ring 503 and the inner box body 504 will not move under the action of gravity, and thus the space formed by the inner box body 504 and the outer box body 1 will be increased, and will stop when it reaches the appropriate position.

[0024] As shown in Figure 3 and Figure 4 , the positioning assembly 6 comprises a plurality of clamping grooves 601 formed in the circumferential outer wall of one of the connecting columns 502, the plurality of clamping grooves 601 are vertically distributed, and the top outer wall of the moving ring 503 is rotationally connected with a plug-in plate 602 at one corner, which can be plugged into the plurality of clamping grooves 601.

[0025] The top outer wall of the plug-in plate 602 is provided with a mounting groove 603, and a rubber column 604 is bonded inside the mounting groove 603, and a part of the top of the rubber column 604 extends out of the mounting groove 602.

[0026] When one end of the plug-in plate 602 is actuated, it will be flipped on the top of the moving ring 503, and then gradually plugged into the corresponding one of the clamping grooves 601, during which the rubber column 604 is deformed and shortened under the extrusion of the clamping groove 601, and the reaction force is applied to the inner wall of the clamping groove 601, which can limit the position of the plug-in plate 602 and ensure that the connection state cannot be randomly released.

[0027] As shown in Figure 1 and Figure 2 , the outer box body 1 is slidingly sleeved with two connecting rings 2, the two connecting rings 2 are respectively located opposite to the two mounting rings 501, and the connecting rings 2 and the mounting rings 501 which are close to each other are threadedly connected with a plurality of connecting bolts 3.

[0028] The two connecting rings 2 are sleeved on the two outer box bodies 1, and then the two connecting rings 2 and the two mounting rings 501 are connected together through the connecting bolts 3, thereby forming a complete individual, which can increase the overall strength of the carton and prevent it from collapsing due to external force, and is easy to disassemble and assemble for repeated use.

[0029] As shown in Figure 4As shown, the arc surface 605 is provided on one corner of the connecting column 502 away from the insertion plate 602, which can coincide with the outer wall of the connecting column 502, so that the insertion plate 602 will not extend out of the card slot 601 after clamping, thereby avoiding the extrusion of the article to the insertion plate 602 to make it separate from the card slot 601.

[0030] As shown in the drawings, Figure 4 As shown, the two edges of the plurality of card slots 601 are provided with a rounded corner 606, so that the insertion process of the insertion plate 602 and the card slot 601 has a higher fault tolerance.

[0031] As shown in the drawings, Figure 2 and Figure 3 As shown, the waterproof sleeve 4 is provided at the bottom of the inner box 504, which is made of polypropylene film and has good waterproofness, moisture resistance and pollution resistance, so as to avoid the softening and damage of the inner box 504 when contacting with rainwater.

[0032] The utility model provides a kind of carton with space adjusting structure, specific working principle as follows:

[0033] When the device is installed, first, the moving ring 503 is sleeved outside the four connecting columns 502, then the bottom one mounting ring 501 is fixed with the four connecting columns 502, then the combination is inserted into the outer box 1, then the two connecting rings 2 are sleeved outside the two outer boxes 1, and then the two connecting rings 2 are connected with the two mounting rings 501 by connecting bolts 3, thereby forming a complete individual, which can increase the overall strength of the carton, and will not collapse randomly due to external force, and can be easily disassembled and assembled for repeated use. If the individual to be packed is large, the outer box 1 is pulled upward, and the components connected thereto are driven to move upward synchronously, the moving ring 503 and the inner box 504 will not move under the action of gravity, and the space formed by the inner box 504 and the outer box 1 will increase accordingly. When it reaches the appropriate position, stop, and then move one end of the insertion plate 602, which will be flipped at the top of the moving ring 503, and then gradually inserted into the corresponding card slot 601. During this period, the rubber column 604 is deformed and shortened under the extrusion of the card slot 601, and the reaction force is applied to the inner wall of the card slot 601, which can limit the position of the insertion plate 602 and ensure that the connection state will not be randomly released. Since the stress direction of the insertion plate 602 is perpendicular to its rotation direction during use, the external force will not change the position of the insertion plate 602, and vice versa.

[0034] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
