Description

A pressure-resistant carton Technical Field

[0001] The present invention relates to the technical field of carton packaging, in particular to a pressure-resistant carton. Background Art

[0002] At present, the compressive performance of compression cartons is one of the important physical performance indicators for evaluating their quality, and is also an important condition for designing compression cartons. The compression test can reflect the comprehensive characteristics of the entire box-making process and the safety performance of the carton in use. Technical issues

[0003] The authorization announcement number in the existing technology is: CN215323889U, and the name is a pressure-resistant carton, which includes a box body, a support plate, a positioning groove and a support column. The support plate reinforces the four walls to ensure the stability of the bottom, and the positioning groove enhances the structural stability. The central support column is provided with four slots, each slot is equipped with a card plate, which is tightly plugged into the positioning slot to enhance the overall strength. This patent has excellent pressure resistance, protects the internal goods intact, extends the service life, and the internal space is flexibly divided, which is convenient for the classification and storage of items. It is highly practical and worthy of wide promotion and application.

[0004] However, when this patent is in use, the support columns cannot be tightly connected to the box body, so that the support columns will deviate when the box is in use, resulting in the partition and the box body being not firmly installed. When this patent is in use, the box body needs to be sealed with tape after the things inside the box are loaded. For the operator, unpacking and sealing the box is cumbersome and inconvenient to use.

[0005] The prior art authorization announcement number is: CN218401421U, and the name is a pressure-resistant carton, which includes a bottom cardboard, which is reinforced by long side panels and wide side panels. A first outer vertical board is added between the front and back sides of the bottom cardboard to improve the pressure resistance. Two sets of cover cardboards are fixed to the long side panels to form a complete box structure. The internal space is divided by first and second card strips to facilitate the storage of items. Connecting pillars increase the compressive strength of the carton and make it more stable. This carton not only has strong pressure resistance and long service life, but also has flexible internal space division and strong practicality, making it an ideal packaging container;

[0006] However, when this patent is used, since the connecting plates cannot be tightly connected to the box body, the connecting plates may easily run off during the use of the carton, making the connection between the box body and the connecting plates loose. Technical Solutions

The bottom of the support column 9 is fixedly connected to an insert block 11 by screws. A card plate 10 is installed on the support column 9. An installation component is provided inside the insert block 11. The installation component includes a driving shaft 101. A rotating block 102 is fixedly connected to the top of the driving shaft 101 by screws. A driving gear 103 is fixedly sleeved on the outer circumference of the driving shaft 101. Two symmetrically arranged sliding blocks 104 are slidingly assembled inside the insert block 11. One side of the sliding block 104 is fixedly connected to a fixed rack 108 by a screw, and the two fixed racks 108 are engaged with the driving gear 103. The other side of the sliding block 104 is fixedly connected to a clamping block 105 by a screw. The interior of the inserting block 11 is fixedly connected to a guide rod 106. Through the arrangement of the driving shaft 101, the driving gear 103 and other structures, when the support column 9 needs to be installed inside the box 1, the rotating block 102 is rotated to drive the driving gear 103 to rotate, drive the two sliding blocks 104 to slide toward each other, drive the two clamping blocks 105 to slide toward each other, and after the inserting block 11 is inserted into the mounting block 8, the knob is released to tightly connect the support column 9 and the box 1, making the box 1 more secure.

[0026] Please refer to Figure 1. The top of the box body 1 is movably hinged with an upper cover 2, and the top of the upper cover 2 is fixedly connected with a belt 3. A Velcro male buckle 4 is provided on the belt 3, and a Velcro female buckle 5 is provided on one side of the box body 1. Through the arrangement of the belt 3, Velcro male buckle 4 and other structures, when the box body 1 is loaded with things, the upper cover 2 of the box body 1 is closed, and the belt 3 is pulled down with force. After confirming that the upper cover 2 and the box body 1 are tightly connected, the Velcro male buckle 4 on the belt 3 is attached to the female buckle on one side of the box body 1, so that the box sealing is more convenient.

[0027] Please refer to Figures 4-5. A sliding groove is provided inside the sliding block 104, and the sliding block 104 is slidably connected inside the sliding groove. A return spring 107 is provided on the outside of the guide rod 106, and the return spring 107 is jointly connected between the sliding block 104 and the inner wall of the sliding groove. A rotating groove is provided inside the insert block 11, and the driving shaft 101 is rotatably installed inside the rotating groove. A hole groove is provided inside the sliding block 104, and the guide rod 106 passes through the inside of the hole groove. A gear groove is provided inside the insert block 11, and the driving gear 103 is rotatably installed inside the gear groove. A rack groove is provided inside the insert block 11, and the fixed rack 108 is slidably connected inside the rack groove.

[0028] The specific implementation process of the present invention is as follows: when the box body 1 needs to install the support column 9, the operator first aligns the four card plates 10 on the support column 9 with the four slide rails 6 inside the box body 1, drives the support column 9 to slide downward along the slide rail 6, and the support column 9 drives the insert block 11 to slide downward. When the insert block 11 is inserted into the interior of the mounting block 8, the mounting block 8 slowly pushes the sliding block 104 into the interior of the insert block 11 along the inclined surfaces of the two card blocks 105. The two sliding blocks 104 slide into the interior of the insert block 11 along the two guide rods 106 and squeeze the two return springs 107 until the two card blocks 105 are inserted into the interior of the mounting block 8. Slot, when the operator needs to disassemble the support column 9, he rotates the rotating block 102, the rotating block 102 drives the driving shaft 101 to rotate, the driving shaft 101 drives the driving gear 103 to rotate, the driving gear 103 drives the two fixed racks 108 to slide toward each other, the fixed racks 108 drive the two sliding blocks 104 to slide toward each other along the two guide rods 106, the two sliding blocks 104 drive the two card blocks 105 to slide toward each other inside the insertion block 11, and then the operator withstands the pressure of the reset spring 107 and takes the insertion block 11 out of the mounting block 8 to complete the disassembly, making the box body 1 more secure when used;

[0029] Furthermore, when the box 1 is filled with things and needs to be sealed, the upper cover 2 is closed, and the belt 3 on the upper cover 2 is tightened downward to tightly connect the upper cover 2 and the box 1. Then, the Velcro male buckle 4 on the belt 3 is attached to the Velcro female buckle 5 on one side of the box 1, so that the box 1 and the upper cover 2 do not need to use tape to seal the box 1, making it more convenient to seal the equipment.

[0030] When the box 1 falls to the ground, inertia drives the items inside the box 1 to squeeze the buffer pad 15, and the buffer pad 15 drives the four inner columns 13 to slide into the outer column 12 and squeeze the buffer spring 14 inside the outer column 12, so that when the box 1 is impacted, it can better protect the items inside the box 1.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
