Description

Technical Field

[0001] The utility model relates to the technical field of foam boxes, in particular to a foam box with a buffering effect. Background Art

[0002] A foam box is a box-type packaging container made of foam material or porous plastic, which is mainly used for the protection and packaging of items. Some valuable items or precious instruments need to further enhance the cushioning effect of the foam box during transportation.

[0003] According to the Chinese patent publication number CN219278304U, "A foam box with a buffering effect", it is mainly described that multiple foam boxes are stacked to reduce the floor space and improve the transportation efficiency. When stacking, the internal buffer mechanism is stuck in the positioning groove. When the foam box is subjected to impact force, the sliding rod and the slider connected between the positioning block and the buffer base and the spring piece greatly absorb the impact force, so that the foam box has a good buffering effect. In this process, when the upper structure of the foam box shakes during transportation, pressure will be generated between the buffer base and the foam box, and tearing and damage will occur between the buffer base and the foam box over time.

[0004] Therefore, a foam box with a buffering effect is proposed to solve the problem that when the upper structure of the foam box shakes during transportation, pressure will be generated between the buffer base and the foam box, which will eventually cause tearing and damage between the buffer base and the foam box. Utility Model Content

[0005] The technical problem to be solved by the utility model is as follows: During this process, when the upper structure of the foam box shakes during transportation, pressure will be generated between the buffer base and the foam box, and over time, tearing and damage will occur between the buffer base and the foam box. Therefore, a foam box with a buffering effect is proposed.

[0007] As a preferred technical solution of the utility model, a round ball is rotatably embedded on the second clamping plate, and the round ball corresponds to the upper box body. The friction force of installing the second clamping plate is reduced by providing the round ball.

[0008] As a preferred technical solution of the utility model, a card strip is fixedly connected to the bottom end of the second card board, and the card strip is plugged with a card slot, which is located on the first card board. By setting the card strip and the card slot, the second card board can be easily installed.

[0009] As a preferred technical solution of the utility model, a triangular bar is fixedly connected to the upper end of the connecting block, and the triangular bar is in contact with the upper box body. By providing the triangular bar, friction can be increased to improve the stability of the two foam boxes stacked on each other.

[0010] As a preferred technical solution of the utility model, a recess is provided on the connecting block and two opposite connecting blocks are mutually engaged. By providing the recess, a buffer structure can be formed on all four sides of the cover to improve the stability of the foam box stacking.

[0011] The utility model has the following advantages: by installing a detachable first clamping plate on the outside of the foam box and the cover to cooperate with the second clamping plate, using a connecting block and a damping belt to provide a connection between the device and the foam box, it can be easily installed and disassembled, and then the cushion block provides anti-collision buffering, thereby improving the stability of the foam boxes when stacked.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3The foam box with a buffering effect shown in the figure comprises a box body 1 and a cover 2, both sides of the cover 2 are in contact with a first card plate 3, the first card plate 3 is placed on the upper side of the cover 2, and the lowest end of the first card plate 3 is lower than the bottom side of the cover 2. The upper end of the first card plate 3 is fixedly connected with a connecting block 4, the connecting block 4 is in contact with the upper end of the cover 2, and a damping belt 5 is fixedly connected between two adjacent connecting blocks 4. The damping belt 5 cooperates with the cushion block 7 to improve the buffering performance of the foam box. At the same time, the first card plate 3 cooperates with the connecting block 4 and the damping belt 5 to be placed on the bottom side of the foam box The upper end of the first card plate 3 contacts the second card plate 6, and the first card plate 3 and the second card plate 6 are both connected with a pad 7 by glue. The pad 7 is made of rubber material. Through grooves 13 are provided on the pad 7 and the second card plate 6. The second card plate 6 is evenly provided with ventilation holes 14 on the upper side of the through grooves 13. The two foam boxes are in contact horizontally or vertically. When a collision occurs, the two contacting pads 7 will produce collision, extrusion and deformation. The air in the through groove 13 will be squeezed and overflow from the ventilation hole 14. The ventilation hole 14 has a small displacement, which can further enhance the buffering effect.

[0018] The upper box body 1 corresponds to the ball 8 , and the ball 8 is rotatably embedded in the second clamping plate 6 . By providing the ball 8 , the friction between the second clamping plate 6 and the box body 1 is reduced.

[0019] Among them, a card slot 10 is opened on the first card board 3, and a card strip 9 is inserted into the card slot 10. The card strip 9 is fixedly connected to the bottom end of the second card board 6. By setting the card strip 9 and the card slot 10, the first card board 3 and the second card board 6 can be conveniently connected.

[0020] Among them, the upper box body 1 is in contact with the triangular bar 11, and the triangular bar 11 is fixedly connected to the upper end of the connecting block 4. By setting the triangular bar 11 in contact with the upper box body 1, the box body 1 is deformed under gravity conditions, thereby improving the stability of the box body 1 when stacked.

[0021] Among them, two relative connecting blocks 4 are mutually engaged, and the recess 12 is located on the connecting block 4. By setting the recess 12, two groups of connecting blocks 4 and damping belts 5 can be set on the upper side of the cover 2 to improve the stability of the foam boxes when stacking.

[0022] Working principle: Place valuables in the box 1, then install the first card board 3 on the cover 2 and limit it through the connecting block 4 and the damping belt 5, then stack the upper box 1, and then insert the card strip 9 of the second card board 6 into the card slot 10. At this time, the gravity of the upper box 1 is pressed on the triangular bar 11, which can improve the stability of the stacking of the boxes 1. At this time, the pads 7 of two adjacent boxes 1 are in contact and are shaken during transportation. Squeeze and contraction will occur between the two relative pads 7. At this time, the air in the through groove 13 is discharged through the ventilation hole 14, which will provide a certain rebound force, thereby achieving a buffering effect.
