Description

Technical Field

[0001] The present application relates to the technical field of packaging boxes, and in particular to a supporting structure inside a packaging box. Background Art

[0002] After the oil bottles for containing the engine oil are filled, six oil bottles are usually placed in a carton for packaging and transportation.

[0003] During transportation, due to vibrations and other factors, the position of the oil bottle in the carton is not restricted, which may cause collisions between the oil bottles and cause dents on the surface of the oil bottle. In severe cases, the oil bottle may be damaged and cause oil leakage.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In order to prevent adjacent engine oil bottles from colliding with each other when the engine oil bottles are placed in a packaging box for transportation, the present application provides a support structure inside the packaging box.

[0006] The present application provides a packaging box inner support structure, which adopts the following technical solution:

[0007] A support structure inside a packaging box includes a horizontally arranged limit plate and a support plate arranged on a side wall away from the limit plate, wherein the lower end surface of the support plate is arranged lower than the lower end surface of the limit plate, and the upper end of the limit plate is provided with a plurality of limit grooves for placing engine oil bottles.

[0008] By adopting the above technical solution, after the limiting plate and the supporting plate are placed in the packaging box, the lower end of the engine oil bottle can be inserted into the limiting groove, and the limiting plate is used to limit the position of the engine oil bottle in the packaging box, so that adjacent engine oil bottles are less likely to collide with each other, thereby preventing the engine oil bottle from being damaged.

[0009] Optionally: A first baffle plate extending downward is provided on two side walls of the limiting groove that are away from each other, and one end of the first baffle plate away from the limiting plate is used to abut against the side wall of the engine oil bottle.

[0010] By adopting the above technical solution, the first baffle is used to apply a force toward the center of the limiting groove to the engine oil bottle, thereby increasing the friction between the first baffle and the engine oil bottle, making it difficult for the engine oil bottle to fall out of the limiting groove, thereby stably limiting the position of the engine oil bottle in the packaging box.

[0011] Optionally: a second baffle is provided at the lower end of the first baffle, and the end of the second baffle away from the first baffle can abut against the second baffle of the adjacent limiting groove, and the second baffle arranged close to the support plate can abut against the support plate.

[0012] By adopting the above technical solution, the second baffle plate is abutted against the second baffle plate of the adjacent limiting groove, so that the second baffle plate applies a force toward the middle of the limiting groove to the first baffle plate, so that the first baffle plate can stably maintain abutment with the engine oil bottle.

[0013] Optionally: a third baffle is further provided at one end of the second baffle away from the first baffle, the second baffles of adjacent limiting grooves abut against each other, and the second baffle can abut against the support plate.

[0014] By adopting the above technical solution and utilizing the stable connection between the third baffle plate and the adjacent third baffle plate, the second baffle plates can stably apply thrust to each other, so that the first baffle plate can stably maintain contact with the engine oil bottle.

[0015] Optional: The third baffle is arranged above the second baffle.

[0016] By adopting the above technical solution, the folding directions of the first baffle, the second baffle and the third baffle are consistent, so that they can be formed in one go during the indentation processing, making the production of the internal support structure more convenient.

[0017] Optionally: the bending lines of the first baffle and the second baffle are arranged at an angle to the horizontal plane, and the inclination directions of the bending lines on the same limiting groove are opposite.

[0018] By adopting the above technical solution, when the engine oil bottle moves upward, the engine oil bottle can apply a force to the first baffle plate along the bending line to move away from the limiting groove, so that when the engine oil bottle moves upward, the lower ends of the two first baffle plates it abuts will not approach each other, so that the engine oil bottle can be taken out of the limiting groove normally.

[0019] Optionally: the sum of the widths of the two second baffles connected to the third baffle that can abut against each other is greater than or equal to the distance between the limiting grooves connected to the two second baffles.

[0020] By adopting the above technical solution, the distance between the lower ends of the two first baffles is smaller than the width of the limiting groove. When the engine oil bottle is inserted into the limiting groove, the first baffle can maintain contact with the engine oil bottle, so that the position of the engine oil bottle is stably limited.

[0021] Optionally, the shape of the limiting groove matches the bottom contour of the engine oil bottle.

[0022] By adopting the above technical solution, the engine oil bottle can be inserted into the limiting groove, and the gap between the limiting groove and the engine oil bottle is small, so that the limiting groove can stably limit the position of the engine oil bottle.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The position of the oil bottle is limited by the limit groove on the limit plate, so that when the oil bottle is transported in the packaging box, adjacent oil bottles will not collide and be damaged;

[0025] 2. By utilizing the cooperation of the first baffle plate, the second baffle plate and the third baffle plate, the friction between the first baffle plate and the engine oil bottle is increased, so that the engine oil bottle is not easy to be separated from the limiting groove, so that the engine oil bottle can be stably limited.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] The present application discloses a support structure inside a packaging box, such as Figure 1 As shown, it includes a horizontally arranged limiting plate 1 and two supporting plates 2 integrally formed on the side wall where the long side of the limiting plate 1 is located. The limiting plate 1 and the supporting plate 2 are both corrugated cardboards. The two supporting plates 2 are bent downward, and the lower end surface of the supporting plate 2 is lower than the lower end surface of the limiting plate 1. The four side walls of the limiting plate 1 can abut against the inner wall of the packaging box, and the lower end surface of the supporting plate 2 abuts against the bottom surface of the inner cavity of the packaging box. The upper end of the limiting plate 1 is provided with a plurality of limiting grooves 11 for limiting the position of the engine oil bottle. The limiting groove 11 penetrates the lower end surface of the limiting plate 1. The engine oil bottle is inserted into the limiting groove 11, and the shape of the limiting groove 11 is adapted to match the bottom contour of the engine oil bottle, so that the engine oil bottle is easier to insert into the limiting groove 11, and the limiting plate 1 is used to limit the position between adjacent engine oil bottles, so that after the engine oil bottles are placed in the packaging box, it is not easy for the adjacent engine oil bottles to come into contact, so that the engine oil bottles are not easy to be damaged during transportation.

[0031] like Figure 2 As shown, the first baffle plate 12 bent downward is integrally formed on both side walls of the limiting groove 11 parallel to the support plate 2, the second baffle plate 13 bent toward the support plate 2 is integrally formed at the lower end of the first baffle plate 12, and the third baffle plate 14 bent toward the limiting plate 1 is integrally formed at one end of the second baffle plate 13 away from the first baffle plate 12. The lower end of the first baffle plate 12 can abut against the side wall of the engine oil bottle, thereby limiting the position of the engine oil bottle, so that the engine oil bottle is not easy to fall off from the limiting groove 11.

[0032] The third baffles 14 on adjacent limiting grooves 11 can abut against each other, and the third baffle 14 close to the support plate 2 can abut against the support plate 2, thereby utilizing the force of the third baffle 14 to restore deformation to apply a force to the first baffle 12 to move toward the oil bottle, so that the first baffle 12 can remain in abutment with the oil bottle.

[0033] In order to make the first baffle plate 12 maintain ground contact with the engine oil bottle, the sum of the widths of the two second baffle plates 13 connected by the third baffle plate 14 that can abut against each other is greater than the distance between the limiting grooves 11 connected by the two second baffle plates 13, and the width of the second baffle plate 13 disposed close to the support plate 2 is greater than the distance between the limiting groove 11 connected by the second baffle plate 13 and the support plate 2. When the third baffle plates 14 abut against each other or the third baffle plate 14 abuts against the support plate 2, the lower ends of the first baffle plate 12 and the second baffle plate 13 are both inclined toward the engine oil bottle, so that when the engine oil bottle is disposed between the two first baffle plates 12, the first baffle plate 12 can always abut against the side wall of the engine oil bottle.

[0034] After the first baffle 12 abuts against the oil bottle, the oil bottle will drive the lower end of the first baffle 12 to move toward the oil bottle when it moves upward, so that the pressure between the oil bottle and the first baffle 12 is too large, which affects the upward movement of the oil bottle. Therefore, the bending lines of the first baffle 12 and the second baffle 13 are inclined, one end of the bending line is inclined upward, and the inclination direction of the bending line on the same limiting groove is opposite, so that when the oil bottle moves upward, a force along the bending line can be applied to the first baffle 12, so that the two first baffles 12 in the same limiting groove 11 are separated from each other, so that the process of taking the oil bottle out of the limiting groove 11 is not easily affected.

[0035] The implementation principle of this embodiment is: fold the first baffle 12 downward, fold the second baffle 13 toward the support plate 2, then fold the third baffle 14 upward and make the adjacent third baffles 14 abut against each other, fold the support plate 2 downward and make the third baffle 14 abut against the support plate 2, then put the limit plate 1 into the packaging box, and insert the engine oil bottle into the limit groove 11.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
