[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-7The utility model provides the following technical solutions: a honeycomb paper foam box cover limiting structure, including an elevated box body 1 and a plurality of box covers 2, the elevated box body 1 including a plurality of cavities, the cavities are used to place articles, the box covers 2 are covered on the elevated box body 1 to cover the cavities, the box covers 2 are consistent with and match the number of cavities, each box cover 2 is covered on each cavity, and two limiting blocks 5 are embedded on one side of the lower opening of each box cover 2, the two limiting blocks 2 are distributed on both sides of the box cover 2, the limiting blocks 5 protrude to the back of the box cover 2, and the two limiting blocks 5 are just offset and limited by the elevated box body 1 on both sides of the cavity in the elevated box body 1, so that the gap between the plurality of box covers 2 is a, and the gap between the box covers 2 is controllable and consistent, so that the surface of the honeycomb paper foam box is more beautiful.
[0020] Specifically, the gap a between the box covers 2 is 3-5 mm. The gap a between the box covers 2 is controllable and consistent through the limiting block 5, which improves the requirements of each part and surface difference. The gap is generally set according to customer requirements.
[0021] Specifically, a square boss 51 is provided in the middle of the limit block 5. The setting of the boss enables the limit block 5 to be stably snapped onto the elevated box body 1 on both sides of the cavity. Square steps 52 are provided around the boss 51 on the limit block 5, so that the limit block 5 can be stably embedded in the box cover 2.
[0022] Specifically, the transverse width of the limit block 5 is b, b is 51mm, the longitudinal width of the limit block 5 is generally set to be consistent with the transverse width, the transverse width of the boss 51 on the limit block 5 is c, c is 27mm, the longitudinal width of the boss 51 on the limit block 5 is generally set to be consistent with the transverse width, the transverse width of the step 52 on one side of the boss 51 on the limit block 5 is d, d is 12mm, the transverse width of the steps 52 on both sides of the boss 51 on the limit block 5 and the longitudinal width of the steps 52 on both sides of the boss 51 are generally set to be consistent, the setting of the transverse and longitudinal widths of the steps 52 on the limit block 5 is to ensure the bonding strength between the limit block 5 and the box cover 2, so that the limit block 5 has a strong bonding force and is firmly bonded, the overlapping height of the boss 51 on the limit block 5 and the elevated box body 1 is f, f is 5-6mm, and the overlapping height of the boss 51 and the elevated box body 1 must have a certain distance, which is set to play a role in limiting The lap gap between the boss 51 on the limit block 5 and the elevated box body 1 is g, and g is 0.5mm. A gap should be set between the lap gap between the boss 51 on the limit block 5 and the elevated box body 1 so that the box cover 2 can be closed smoothly without jamming. However, if g is too large, it cannot play a limiting role. The lateral guide slope of the boss 51 on the limit block 5 is h, and h is 9°. The longitudinal guide slope of the boss 51 on the limit block 5 is p, and p is 5°. The lateral and longitudinal dimensions of the boss 51 are wide at the bottom and narrow at the top, which plays a guiding role in closing the limit block 5. The outer circumference of the top of the boss 51 on the limit block 5 is rounded, which also plays a guiding role in closing the limit block 5. The depth of the limit block 5 embedded in the box cover 2 is L, and L is 0.5mm. L should not be set too large to affect the aesthetics of the surface of the box cover 2. The total height of the limit block 5 is m, and m is 25mm. The height of the boss 51 is n, and n is 21mm.
