[0032] As traditional food packaging boxes do not have a pressure-resistant structure, the present invention can have a certain buffering effect through the pressure-resistant component, thereby reducing the impact of pressure on the food inside the packaging box. When the food packaging box is subjected to a certain squeezing force, an alarm can be issued to remind the staff to pay attention to avoid further squeezing. As traditional food packaging boxes do not have a limiting mechanism inside, the present invention can flexibly fix the food on the inner wall of the packaging box through the limiting component, thereby reducing the impact of shaking of the packaging box during transportation on the food.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example:

[0035] See also Figure 1 and Figure 2As shown, a pressure-resistant food packaging box comprises a box body 1, a pressure-resistant plate 2 is slidably connected to the side of the box body 1, and there are four pressure-resistant plates 2. A buffer frame 3 is slidably connected to the inner cavity of the box body 1, and a top cover 4 is slidably connected to the top of the buffer frame 3. The main materials of the box body 1, the pressure-resistant plate 2, the buffer frame 3 and the top cover 4 are made of harder plastic to ensure that no concave deformation will be directly generated during the extrusion process, that is, to ensure that the pressure-resistant component 5 can produce a pressure-resistant effect. Pressure-resistant components 5 are arranged on both sides of the top of the box body 1, a buffer component 6 is fixedly installed on the inner wall of the box body 1, and a limiting component 7 is arranged on the bottom wall of the box body 1. Support frames 8 are fixedly installed on the four corners of the box body 1 and the top cover 4. Food is placed in the inner cavity of the box body 1, and the food is limited by the limiting component 7 to prevent the food from shaking inside the box body 1 during transportation. The support frame 8 is used to reinforce the box body 1 and the top cover 4. The corner of the box body 1, the anti-pressure plate 2 protrudes from the inner cavity of the box body 1, and the buffer component 6 can make the anti-pressure plate 2 have a buffering force when it touches other objects, thereby reducing the physical property rights impact of the outer surface of the anti-pressure plate 2 on the inner cavity of the box body 1 when squeezed. The anti-pressure component 5 is used to prevent the upper end of the box body 1 from being squeezed, that is, the pressure borne on the upper surface of the top cover 4, and the upper surface of the top cover 4 is most susceptible to external force, thereby causing the food to be squeezed in the inner cavity of the box body 1. The anti-pressure component 5 makes it possible to have an anti-pressure effect between the top cover 4 and the buffer frame 3, and between the buffer frame 3 and the box body 1. Therefore, the pressure on the upper surface of the top cover 4 causes preliminary buffering through the anti-pressure component 5, and then an alarm is issued through the anti-pressure component 5 to remind the staff to check whether the upper part of the packaging box is squeezed. At the same time, it also has a secondary buffering effect, so as to provide sufficient time for the staff to check.

[0036] See also Figure 3 and Figure 4 As shown, the anti-pressure component 5 includes a first anti-pressure mechanism 51, an alarm mechanism 52 is arranged below the first anti-pressure mechanism 51, a second anti-pressure mechanism 53 is arranged above the alarm mechanism 52, and the second anti-pressure mechanism 53 is located between the first anti-pressure mechanism 51 and the second anti-pressure mechanism 53. The first anti-pressure mechanism 51 and the second anti-pressure mechanism 53 are both used for buffering to prevent the food in the inner cavity of the box body 1 from being damaged when the top cover 4 is subjected to pressure. The alarm mechanism 52 is used to sound an alarm after the first anti-pressure mechanism 51 is subjected to pressure. At this time, the second anti-pressure mechanism 53 begins to produce an anti-pressure effect. The first anti-pressure mechanism 51 is used to prevent extrusion between the top cover 4 and the buffer frame 3, and the second anti-pressure mechanism 53 is used to prevent extrusion between the buffer frame 3 and the box body 1. Therefore, when food is placed in the inner cavity of the box body 1, the upper part of the box body 1 has anti-pressure effects on both sides, which improves the fault tolerance when the packaging box is squeezed and reduces the damage caused to the food when it is subjected to pressure.

[0037] See also Figure 4 , Figure 5 and Figure 6As shown, the first anti-pressure mechanism 51 includes a first connecting frame 511, a fixing rod 512 is fixedly installed on the outer surface of the first connecting frame 511, a sliding seat 513 is slidably connected to the outer surface of the fixing rod 512, a first spring 514 is arranged in the middle part of the fixing rod 512, a connecting strip 515 is rotatably connected to the inner cavity of the sliding seat 513, an end of the connecting strip 515 away from the sliding seat 513 is rotatably connected to the anti-pressure strip 516, sliding rods 517 are fixedly installed at both ends of the anti-pressure strip 516, a second spring 518 is sleeved on the outer surface of the sliding rod 517, a ball 519 is rollingly connected to the bottom end of the sliding rod 517, the sliding seat 513 and the first connecting frame 511 are slidably connected, and there are two sliding seats 513 on one first connecting frame 511, the first spring 514 is located between the two sliding seats 513, and the sliding rod 517 and the fixing rod 512 are slidably connected. Sliding connection, the second spring 518 is located between the fixed rod 512 and the anti-compression strip 516, the sliding rod 517 and the first connecting frame 511 are slidingly connected, the first connecting frame 511 and the inner wall of the buffer frame 3 are fixedly connected, the bottom walls at both ends of the top cover 4 are in close contact with the anti-compression strip 516, the sliding rod 517 and the inner cavity of the buffer frame 3 are slidingly connected, when the top cover 4 is subjected to pressure, the top cover 4 is squeezed by the anti-compression strip 516, and the anti-compression strip 516 is pressed and approaches the first connecting frame 511. At this time, the second spring 518 is compressed, and at the same time, the connecting strip 515 rotates to make the slide seat 513 slide on the fixed rod 512 and squeeze the first spring 514, so that when the top cover 4 is subjected to force, a certain flexible force is generated between the top cover 4 and the buffer frame 3 through the first anti-compression mechanism 51, thereby reducing the damage caused to the top cover 4 during the squeezing process.

[0038] See also Figure 4 , Figure 5 and Figure 7As shown, the alarm mechanism 52 includes a second connecting frame 521, the inner cavity of the second connecting frame 521 is rotatably connected to the first threaded rod 522, the outer surface of the second connecting frame 521 is slidably connected to the slider 523, the slider 523 and the first threaded rod 522 are threadedly connected, and the threads at both ends of the first threaded rod 522 are in opposite directions, the two ends of the second connecting frame 521 are slidably connected to the tilting block 524, the outer surface of the tilting block 524 is fixedly installed with an alarm 525, the outer surface of the tilting block 524 is provided with a button 526, the alarm 525 and the button 526 are electrically connected, and the pressing of the button 526 controls the alarm 525 to sound an alarm, and the two ends of the second connecting frame 521 are fixedly connected to the sixth spring 527, and the sixth spring 527 is used to restore the tilting The original position of the inclined block 524, when the top cover 4 is not subjected to the extrusion force, the rolling ball 519 and the inclined block 524 are in inclined contact, the sixth spring 527 is fixedly connected to the inclined block 524 at one end away from the second connecting frame 521, the height of the top of the slider 523 is flush with the button 526, the bottom end of the second connecting frame 521 is fixedly connected to the inner wall of the box body 1, the outer surface of the inclined block 524 is an inclined surface, and the cleaning surface is in contact with the rolling ball 519, the sliding rod 517 is slidably connected to the inner cavity of the storage hole 528, and the second anti-pressure mechanism 53 includes a first connecting block 531, the first connecting block 531 is fixedly connected to the upper surface of the inclined block 524, the top inner cavity of the first connecting block 531 is rotatably connected to the roller 532, and the inner cavity of the first connecting block 531 is fixedly connected to the anti-pressure mechanism The third spring 534 is sleeved on the outer surface of the anti-compression rod 533, and a slip ring 535 is slidably connected to the top of the anti-compression rod 533. The third spring 534 is located between the first connecting block 531 and the slip ring 535. The bottom end of the anti-compression rod 533 is fixedly sleeved with a fixing ring 536, so that the anti-compression rod 533 can be close to the bottom end of the support block 537 when it is not squeezed, so as to facilitate secondary buffering when the top cover 4 moves down. The outer surface of the buffer frame 3 is fixedly installed with a support block 537, and a receiving groove 538 is provided at one end of the support block 537. The roller 532 is slidably connected to the bottom end of the support block 537. The diameter of the slip ring 535 is larger than the width of the receiving groove 538, and the diameter of the top end of the first connecting block 531 and the anti-compression rod 533 is smaller than the diameter of the top end. The width of the storage groove 538 ensures that the support block 537 can drive the slip ring 535 to squeeze the third spring 534 to produce a pressure-resistant effect when pressed down. At the same time, the storage groove 538 can accommodate the first connecting block 531, and the first connecting block 531 loses its supporting effect, so that the rigid connection between the top cover 4 and the box body 1 is changed to a flexible connection. When the slide bar 517 and the storage hole 528 are inserted into each other, the first connecting block 531 is located in the inner cavity of the storage groove 538. At this time, the button 526 and the slider 523 are in contact and squeezed. When the top cover 4 is subjected to pressure, the first pressure-resistant mechanism 51 is squeezed, and the pressure-resistant strip 516 is squeezed toward the first connecting frame 511 to drive the slide bar 517 to move downward. The downward movement of the slide bar 517 drives the rolling ball 519 to squeeze the inclined surface of the inclined block 524.The inclined surface of the tilting block 524 is squeezed, driving the tilting block 524 to slide on the second connecting frame 521. When the compression strip 516 approaches the first connecting frame 511, the button 526 approaches the slider 523, causing the slider 523 to squeeze the button 526. The pressing of the button 526 controls the alarm 525 to sound an alarm, reminding the staff that the top of the packaging box is squeezed, so that measures can be taken quickly to avoid further losses. By rotating the first threaded rod 522 to make the slider 523 slide on the second connecting frame 521, the slider 523 is ensured to be The distance between the first connecting block 531 and the first connecting block 531 is appropriate, so that when the sliding rod 517 moves downward, the rolling ball 519 can drive the tilting block 524 to move, so that the button 526 and the sliding block 523 are squeezed and an alarm is issued. During the movement of the tilting block 524, the tilting block 524 drives the first connecting block 531 to move. The movement of the first connecting block 531 drives the roller 532 to roll in the inner cavity of the supporting block 537, so that the roller 532 is close to the receiving groove 538. When the rolling ball 519 moves to the inner cavity of the receiving hole 528, the first connecting block 531 is inserted into the receiving groove 538. In the inner cavity, before the first connecting block 531 does not enter the inner cavity of the receiving groove 538, the bottom ends of the roller 532 and the support block 537 are in contact. At this time, the top cover 4 and the box body 1 are rigidly connected. When the first connecting block 531 is received in the inner cavity of the receiving groove 538, the pressure on the top cover 4 is not relieved, but increased, so that the support block 537 squeezes the slip ring 535. At this time, the slip ring 535 squeezes the third spring 534. At this time, the top cover 4 and the box body 1 are rigidly connected because the roller 532 is separated from the support of the support block 537. The connection is a flexible connection, which has a secondary pressure resistance effect and reduces the probability of damage to the packaging box under pressure. That is, when the top cover 4 is squeezed, the top cover 4 generates a squeezing force on the first pressure resistance mechanism 51. The first pressure resistance mechanism 51 resists pressure for the first time. As the pressure increases, the alarm mechanism 52 sounds an alarm. When the ball 519 is inserted into the receiving hole 528, the support block 537 squeezes the slip ring 535. The secondary buffering facilitates the staff to take measures and provides valuable time, thereby avoiding further losses and reducing the damage to food during the squeezing process.

When the side of the box body 1, that is, the anti-pressure plate 2 is subjected to pressure, the anti-pressure plate 2 drives the buffer rod 62 to squeeze the fourth spring 63 to compress the fourth spring 63. The elastic force of the fourth spring 63 can be expanded and contracted to reduce the shaking caused by the collision. At the same time, the anti-pressure plate 2 can be stored in the inner cavity of the box body 1 to reduce the distance in contact with the external force, so that the anti-pressure plate 2 can have a buffering effect when extrusion occurs, thereby reducing the damage to the food when the side of the box body 1 is squeezed.

The adjusting block 781 is connected to the second threaded rod 77 by threads, and the second threaded rod 77 is connected by threads. The threads at both ends of 7 are in opposite directions. The spacing of the adjusting plate 71 is adjusted according to the size of the food. The fixing bolt 73 is disengaged and inserted into the jack to move the adjusting plate 71 on the box body 1. When the adjusting plate 71 moves to a suitable position, the fixing bolt 73 is rotated in the inner cavity of the second connecting block 72 to insert the fixing bolt 73 and the jack. The rotation of the second threaded rod 77 drives the clamping mechanism 78 to move on the elastic plate 76, so that the distance of the clamping mechanism 78 is adjusted to the size of the packaged food. At this time, the food is fixed by the clamping mechanism 78, wherein the first floating block 782 can rotate in the inner cavity of the adjusting block 781, and the second floating block 782 can rotate in the inner cavity of the adjusting block 781. The floating block 783 can rotate in the inner cavity of the first floating block 782, and the clamping block 784 can rotate in the inner cavity of the second floating block 783, so that the clamping mechanism 78 can fix the food according to the shape of the food. The block on the outer surface of the clamping block 784 is used to increase the friction force during limiting, so as to better limit the food. When the box body 1 shakes during transportation, the elastic plate 76 shakes to make the elastic rod 74 slide in the inner cavity of the adjustment plate 71, driving the fifth spring 75 to be compressed. The elastic force of the fifth spring 75 reduces the vibration generated during shaking, thereby ensuring the stability of the food in the packaging box during transportation and improving the completeness of the food in the packaging box.

[0041] In summary, the limiting assembly 7 is used to limit the position of the food to prevent the food from shaking inside the box body 1 during transportation. The spacing of the adjustment plates 71 is adjusted according to the size of the food, and the fixing bolts 73 are disengaged and inserted into the sockets to move the adjustment plates 71 on the box body 1. When the adjustment plates 71 move to a suitable position, the fixing bolts 73 are rotated in the inner cavity of the second connecting block 72 to engage the fixing bolts 73 and the sockets. The rotation of the second threaded rod 77 drives the clamping mechanism 78 to move on the elastic plate 76, so that the distance of the clamping mechanism 78 is adjusted to the size of the packaged food. At this time, the food is fixed by the clamping mechanism 78. The support frame 8 is used to The corners of the box body 1 and the top cover 4 are reinforced, and the anti-pressure plate 2 protrudes from the inner cavity of the box body 1. When it touches other objects, the buffer component 6 can make the anti-pressure plate 2 have a buffering force, reducing the physical property influence of the outer surface of the anti-pressure plate 2 on the inner cavity of the box body 1 when it is squeezed. The anti-pressure component 5 is used to prevent the upper end of the box body 1 from being squeezed, that is, the pressure borne on the upper surface of the top cover 4. The upper surface of the top cover 4 is most susceptible to external forces, thereby causing the food to be squeezed in the inner cavity of the box body 1. The anti-pressure component 5 makes the top cover 4 and the buffer frame 3 have an anti-pressure effect, and the buffer frame 3 and the box body 1 have an anti-pressure effect, so that the upper surface of the top cover 4 is subjected to pressure through the anti-pressure component 5 performs preliminary buffering, and then the anti-pressure component 5 sends out an alarm to remind the staff to check whether the upper part of the packaging box as a whole is squeezed. At the same time, it also has a secondary buffering effect, that is, the first anti-pressure mechanism 51 and the second anti-pressure mechanism 53 are both used for buffering to prevent the food in the inner cavity of the box body 1 from being damaged when the top cover 4 is under pressure. The alarm mechanism 52 is used to send out an alarm after the first anti-pressure mechanism 51 is under pressure. At this time, the second anti-pressure mechanism 53 begins to produce an anti-pressure effect. The first anti-pressure mechanism 51 is used to prevent squeezing between the top cover 4 and the buffer frame 3, and the second anti-pressure mechanism 53 is used to prevent squeezing between the buffer frame 3 and the box body 1, so that when food is placed in the inner cavity of the box body 1, The top of the box body 1 has pressure-resistant effects on both sides, which improves the fault tolerance when the packaging box is squeezed and reduces the damage to the food when it is under pressure, so as to give the staff sufficient time to check. When the side of the box body 1, that is, the pressure-resistant plate 2, is under pressure, the pressure-resistant plate 2 drives the buffer rod 62 to squeeze the fourth spring 63 to compress the fourth spring 63. The elastic force of the fourth spring 63 can be expanded and contracted to reduce the shaking caused by the collision. At the same time, the pressure-resistant plate 2 can be stored in the inner cavity of the box body 1 to reduce the distance from the contact with the external force, so that the pressure-resistant plate 2 can have a buffering effect when squeezing occurs, thereby reducing the damage to the food when the side of the box body 1 is squeezed.
