[0026] The following is combined with Figure 1 —6 Further details of this application,

[0027] The present application embodiment discloses a stable and highly pressure-resistant packaging box. Figure 1 - Figure 6 A stable and highly pressure-resistant packaging box comprises a box body 1 and a box cover 2; a partition frame 6 is installed at the bottom of the inner wall of the box body 1, a limiting component 4 is installed between the partition frame 6 and the box body 1, an extrusion block 3 is symmetrically fixedly installed at the bottom of the box cover 2, and a second clamping block 8 is fixedly installed at the middle of the two symmetrical outer walls of the two extrusion blocks 3, a portable component 5 for easy carrying is installed at the lower middle of the two symmetrical outer walls of the box body 1, and a support component 7 with a function of enhancing stability is arranged on the inner wall of the partition frame 6;

[0028] The limiting component 4 includes a connecting frame 401 and a fixed frame 405. The connecting frame 401 is symmetrically fixedly installed at the bottom of the inner wall of the box body 1. A sliding groove 402 is opened on the top of the two connecting frames 401. A limiting block 403 is symmetrically slidably installed on the inner wall of the connecting frame 401. A fixed frame 405 is fixedly installed in the middle of the outer wall of the partition frame 6 close to the inner wall of the box body 1. A first spring 406 is fixedly installed at the bottom of the inner wall of the fixed frame 405. Fixed blocks 9 are symmetrically fixedly installed on one side of the inner wall of the two box bodies 1 close to the limiting component 4. The two fixed blocks 9 are located on both sides of the connecting frame 401. The extrusion block 3 presses down on the sliding block 407. When the sliding block 407 is pressed down, it will drive the transmission rod 404 to rotate. When the moving block 407 descends, the transmission rod 404 will push the limit block 403 to move toward the plug-in slot 10 for clamping. A sliding block 407 is fixedly installed on the top of the first spring 406, and the transmission rods 404 are rotatably installed on both ends of the sliding block 407. The ends of the two transmission rods 404 away from the sliding block 407 are rotatably installed on the top of the limit block 403. A fixed seat 408 is symmetrically fixedly installed in the horizontal direction on one side of the partition frame 6 with a fixed frame 405. A storage frame 409 is fixedly installed on one side of the top of the fixed seat 408. A second spring 4010 is fixedly installed in the inner wall of the storage frame 409, and a first clamping block 4011 is fixedly installed on the side of the second spring 4010 close to the partition frame 6.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The limit block 403 is in a "convex" shape, and the top protruding end of the limit block 403 is slidably installed in the sliding groove 402. The fixed seat 408 is in an "L" shape, and the side wall of the protruding part of the fixed seat 408 contacts with the first clamping block 4011. When the first clamping block 4011 contacts with the protruding part of the fixed seat 408, the vertical movement direction of the second clamping block 8 is limited.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The first clamping block 4011 has an arc-shaped cross-section in the vertical direction, the arc-shaped surface of the first clamping block 4011 is located above the second spring 4010, the bottom of the first clamping block 4011 is horizontally arranged, and the bottom of the first clamping block 4011 contacts the outer wall of the second clamping block 8. When the second clamping block 8 is squeezed, the first clamping block 4011 is squeezed into the storage frame 409. When the second clamping block 8 moves to the bottom of the first clamping block 4011 in the vertical direction, the first clamping block 4011 will move outward under the action of the second spring 4010 to limit the second clamping block 8.

[0031] Reference Figure 1 and Figure 5The portable component 5 includes an installation box 501. The installation boxes 501 are fixedly installed at the lower middle parts of the outer walls of both sides of the box body 1 that are symmetrical to each other. Connecting shafts 504 are symmetrically fixedly installed in the inner wall of the installation box 501. The two connecting shafts 504 are respectively sleeved with volute springs 502. One end of the two volute springs 502 is fixedly installed on the installation box 501. The other end of the two volute springs 502 is fixedly installed with a second connecting rope 503. The second connecting rope 503 passes through the top of the installation box 501 and extends to the outside. When it is necessary to carry it, the second connecting rope 503 is pulled and the second connecting rope 503 is pulled out of the installation box 501 for carrying. When it is not in use, the volute spring 502 will drive the second connecting rope 503 to be rolled up, and the second connecting rope 503 is rolled up into the installation box 501.

[0032] Reference Figure 2 and Figure 6 The support assembly 7 includes two connecting seats 701, and the connecting seats 701 are fixedly installed on the top and bottom of the interior of the partition frame 6 respectively. Vertical poles 702 are distributed in a rectangular shape between the two connecting seats 701, and oblique support rods are arranged between the four vertical poles 702. When in use, the connecting seats 701, the vertical poles 702 and the oblique support rods form a triangular component to enhance the stability of the device.

[0033] Reference Figure 2 , Figure 3 and Figure 4 A first connecting rope 4012 is fixedly installed on the side of the first clamping block 4011 away from the partition frame 6. The first connecting rope 4012 extends to the outside through the outer wall of the storage frame 409 and the box body 1. A connecting ring 4013 is fixedly installed on the side of the first connecting rope 4012 away from the second spring 4010.

[0034] Reference Figure 2 , Figure 3 and Figure 4 , plug-in slots 10 are respectively formed on both sides of the fixing block 9 close to the connection frame 401 , and limit blocks 403 are slidably installed in the plug-in slots 10 .

[0035] Working principle: when in use, place the fruit in the inner cavity of the partition frame 6, and after placing the fruit, press the extrusion block 3 on the box cover 2 against the sliding block 407. When the sliding block 407 is pressed down, the transmission rod 404 will be driven to rotate. As the sliding block 407 descends, the transmission rod 404 will push the limit block 403 to move toward the plug-in slot 10 for clamping. When the extrusion block 3 moves downward, it will drive the second clamping block 8 to squeeze the first clamping block 4011 downward. Since the first clamping block 4011 is arc-shaped, when the second clamping block 8 is squeezed, the first clamping block 4011 is squeezed into the storage frame 409. When the second clamping block 8 moves to the bottom of the first clamping block 4011 in the vertical direction, the first clamping block 4011 will move outward under the action of the second spring 4010 to limit the second clamping block 8, thereby limiting the vertical positions of the second clamping block 8, the extrusion block 3 and the box cover 2.

[0036] When the box cover 2 needs to be disassembled, the connecting ring 4013 is pulled to drive the first connecting rope 4012 to move. When the first connecting rope 4012 is pulled, the first clamping block 4011 is driven to be stored in the storage frame 409, and the restriction on the second clamping block 8 is released. At this time, under the action of the first spring 406, the squeezing block 3 will be lifted upward and separated;

[0037] When it is necessary to carry the device, the second connecting rope 503 is pulled out of the installation box 501 for carrying. When not in use, the spiral spring 502 drives the second connecting rope 503 to be rolled up, and the second connecting rope 503 is rolled up into the installation box 501, thereby solving the problem that the existing device has a pull rope fixed on the box body 1 and is inconvenient to store.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
