[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A fruit packaging box locking sealing device includes a box shell 1, a protective cover 2 fixedly connected to the surface of the box shell 1, slots 3 opened on the left and right sides of the box shell 1, a sealing block 4 fixedly connected to the top of the protective cover 2, and a top cover assembly 5 provided on the top of the box shell 1.

[0028] The top cover assembly 5 includes a top plate 501. Circular grooves 502 are provided on the left and right sides of the inner wall of the top plate 501. Circular rods 503 are slidably connected to the inner walls of the two circular grooves 502. Connecting discs 504 are fixedly connected to the opposite sides of the two circular rods 503. Springs 505 are fixedly connected to the opposite sides of the two connecting discs 504. Grooves 506 that cooperate with buckles 508 are provided on the left and right sides of the inner wall of the top plate 501. Control blocks 507 are fixedly connected to the opposite sides of the two circular rods 503. Buckles 508 are fixedly connected to the opposite sides of the two connecting discs 504. A sealing groove 509 that cooperates with a sealing block 4 is provided at the bottom of the top plate 501.

[0029] In this embodiment: the box shell 1 serves to store fruit; the protective cover 2 protects the surface of the box shell 1; the slot 3, in conjunction with the top cover assembly 5, connects the box shell 1 and the top cover assembly 5; the sealing block 4, also in conjunction with the top cover assembly 5, enhances the connection between the top cover assembly 5 and the protective cover 2; and the top cover assembly 5, in conjunction with the box shell 1 and the protective cover 2, serves to store fruit. The top plate 501, circular groove 502, and circular rod 50... 3. Connecting plate 504, spring 505, groove 506, control block 507, buckle 508, and sealing groove 509: After the fruit is placed into the box shell 1, preparations begin for installing the top cover assembly 5. At this time, the circular rod 503 is fixed in the circular groove 502, the spring 505 is in a naturally extended state, and the connecting plate 504, under the action of the spring 505, causes the buckle 508 part to be located in the groove 506, not matching the slot 3 on the box shell 1. The top plate 501 is then aligned with the box shell 1, so that the buckle 508 corresponds to the slot 3 on both sides of the box shell 1. During placement, the edge of the slot 3 presses against the buckle 508, causing the connecting plate 504 to move towards the groove 506, thereby compressing the spring 505. The buckle 508 then retracts into the groove 506. As the top plate 501 continues to move downward until the buckle 508 is fully aligned with the slot 3, the elastic force of the spring 505 pushes the connecting plate 504, causing the buckle 508 to quickly engage in the slot 3, thus achieving a secure connection between the top cover assembly 5 and the housing 1. Simultaneously, the sealing groove 509 at the bottom of the top plate 501 tightly engages with the sealing block 4 at the top of the protective cover 2. A good sealing structure is formed. Throughout the transportation and storage process, the spring 505 continuously provides elasticity to ensure that the buckle 508 is tightly locked in the slot 3, thus ensuring the sealing and stability of the fruit packaging box. When it is necessary to open the packaging box, the operating block 507 is operated to apply force in the opposite direction to the buckle 508, so that the circular rod 503 drives the connecting plate 504 to move, overcoming the elasticity of the spring 505, and causing the buckle 508 to disengage from the slot 3. As the buckle 508 disengages from the slot 3, the top plate 501 can be easily removed and the box shell 1 can be opened.

[0030] Specifically, such as Figure 3 As shown, ventilation holes 6 are provided on the front and rear sides of the top plate 501. A fixing plate 7 is fixedly connected to the inner wall of each ventilation hole 6. An adjusting plate 8 that works with the fixing plate 7 is slidably connected inside each ventilation hole 6. A first circular hole 9 is provided on the surface of the fixing plate 7, and a second circular hole 10 is provided on the surface of the adjusting plate 8.

[0031] Specifically, such as Figure 3 As shown, a frame 11 is fixedly connected inside each of the two ventilation holes 6, and a protective net 12 is fixedly connected inside each of the two frames 11.

[0032] Specifically, such as Figure 3As shown, auxiliary grooves 13 are provided at the top and bottom of the inner wall of the ventilation hole 6, and auxiliary blocks 14 that cooperate with the auxiliary grooves 13 are fixedly connected to the top and bottom of the adjusting plate 8.

[0033] In this embodiment: by setting ventilation holes 6, fixing plates 7, adjusting plates 8, first circular holes 9 and second circular holes 10, the combined design of ventilation holes 6, fixing plates 7, adjusting plates 8, first circular holes 9 and second circular holes 10 can flexibly adjust the ventilation volume inside the fruit box shell 1. Different types of fruits have different requirements for oxygen and carbon dioxide concentrations during storage and transportation. By moving the adjusting plate 8, the degree of overlap of the first circular holes 9 and second circular holes 10 can be changed, and the ventilation area of ​​ventilation holes 6 can be controlled, thereby adjusting the amount of air entering the box shell 1, creating a suitable gas environment for the fruit, delaying the respiration of the fruit, and extending the shelf life. By setting the frame 11 and protective net 12, the problem of dust in the air entering the inside of the box shell 1 can be reduced. By setting the auxiliary groove 13 and auxiliary block 14, the position of the adjusting plate 8 on the inner wall of the ventilation hole 6 can be adjusted.

[0034] Specifically, such as Figure 4 As shown, a splicing groove 15 is provided at the bottom of the inner wall of the housing 1, a splicing block 16 is snapped into the inside of the splicing groove 15, and a partition plate 17 is fixedly connected to the top of the splicing block 16.

[0035] Specifically, such as Figure 4 As shown, soft pads 18 are fixedly connected to both the left and right sides of the partition panel 17, and both soft pads 18 are made of rubber.

[0036] In this embodiment: by setting splicing groove 15, splicing block 16 and partition plate 17, splicing block 16 is spliced ​​with splicing groove 15, and then partition plate 17 divides the space inside box shell 1. By setting soft pad 18, damage to fruit can be reduced.

[0037] Specifically, such as Figure 5 As shown, a square groove 19 is provided on the top of the top plate 501. An adjustment handle 20 is rotatably connected inside the square groove 19. An anti-slip sleeve 21 is fitted on the surface of the adjustment handle 20.

[0038] Specifically, such as Figure 1 , Figure 6 As shown, a mounting frame 22 is fixedly connected to the front side of the protective cover 2, an acrylic plate 23 is fixedly connected inside the mounting frame 22, and a baffle 24 is snapped onto the top of the mounting frame 22.

[0039] In this embodiment: by setting a square groove 19, an adjusting handle 20 and an anti-slip sleeve 21, the user manually contacts the anti-slip sleeve 21 and adjusts the adjusting handle 20 on the inner wall of the square groove 19, thereby facilitating the transfer of the structure. By setting a mounting frame 22, an acrylic plate 23 and a baffle 24, the information card is inserted into the inside of the mounting frame 22. Then, the top of the mounting frame 22 is covered by the baffle 24, and the information card inside the mounting frame 22 is displayed by the acrylic plate 23.

[0040] Working principle: During installation, align the top plate 501 of the top cover assembly 5 with the box shell 1. At this time, the buckle 508 connected to the spring 505 in the circular groove 502 on the inner wall of the top plate 501 is compressed by the edge of the groove 3 on the box shell 1, causing the spring 505 to compress and the buckle 508 to retract into the groove 506. When the top plate 501 continues to move down until the buckle 508 is completely aligned with the groove 3, the spring 505 pushes the connecting plate 504, causing the buckle 508 to quickly engage with the groove 3, thus achieving a firm connection between the top cover assembly 5 and the box shell 1. At the same time, the sealing groove 509 at the bottom of the top plate 501 and the sealing block 4 at the top of the protective cover 2 closely cooperate to form a sealing structure, preventing the entry of external air and moisture, maintaining a stable humidity and gas environment in the box shell 1, and delaying fruit spoilage. During transportation and storage, the spring 505 continuously provides elasticity to ensure the buckle 508 engages with the groove 3. The buckle 508 is fastened to the slot 3 to ensure sealing and stability. When opening, the control block 507 is operated to move the circular rod 503 and the connecting plate 504, overcoming the elasticity of the spring 505 to disengage the buckle 508 from the slot 3, making it easy to open the box shell 1. Different fruits have different requirements for oxygen and carbon dioxide concentrations. The ventilation volume can be changed by moving the adjustment plate 8. The inner wall fixing plate 7 of the ventilation hole 6 is provided with a first circular hole 9, and the adjustment plate 8 is provided with a second circular hole 10. When the adjustment plate 8 is moved, the auxiliary block 14 slides in the auxiliary groove 13 to ensure that the adjustment plate 8 moves smoothly, thereby controlling the ventilation area of ​​the ventilation hole 6 and adjusting the amount of air entering the box shell 1, creating a suitable gas environment for the fruit, delaying respiration, and extending the shelf life. The inner frame 11 and protective net 12 of the ventilation hole 6 can prevent dust from entering and further protect the quality of the fruit.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
