[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a convenient packaging carton, comprising:

[0032] The packaging carton body 1 has a packaging carton lid 2 clipped to the top of the packaging carton body 1. The packaging carton body 1 and the packaging carton lid 2 are equipped with a sealing mechanism. It should be noted that the packaging carton can be sealed quickly and can be reused, making it convenient to operate.

[0033] The encapsulation mechanism includes connector 4, upright 5, base plate 6, spring 7, hanger 8, rotating rod 9, connecting block 10, and fastening rod 11;

[0034] The connector 4 is fixedly installed on the packaging carton body 1. The upright 5 is vertically slidably installed on the connector 4. The top of the base plate 6 is fixedly connected to the upright 5. The spring 7 is fixedly installed between the base plate 6 and the connector 4. The hanger 8 is fixedly installed at the bottom of the packaging carton cover 2. The rotating rod 9 is rotatably installed on the upright 5. The connecting block 10 is fixedly connected to the rotating rod 9 and the fastening rod 11. The fastening rod 11 abuts against the inner side of the hanger 8.

[0035] With the above structure, when the packaging carton cover 2 is fastened, pulling the fastening rod 11 upwards will cause the upright rod 5 to move the base plate 6 upwards, causing the base plate 6 to press against the spring 7. Then, the fastening rod 11 is rotated, causing the fastening rod 11 to move into the hanger 8. Then, the fastening rod 11 is released, at which point the spring 7 returns to its original position, causing the upright rod 5 to move downwards, so that the fastening rod 11 can abut against the inside of the hanger 8. Through the action of the spring 7, a downward pressure can be applied to the hanger 8 to ensure the stability of the packaging carton cover 2 after it is fastened.

[0036] Specifically, the packaging mechanism also includes a connecting strip 13, a first hook and loop fastener 14, and a second hook and loop fastener 15. The connecting strip 13 is fixedly installed on the bottom of the base plate 6, the first hook and loop fastener 14 is fixedly installed on the connecting strip 13, and the second hook and loop fastener 15 is fixedly installed on the connector 4.

[0037] With the above structure, pulling the connecting strip 13 causes it to pass around the guide rod 16, allowing the Velcro 14 to adhere to the Velcro 2 15. This further reinforces the position of the fastening rod 11, ensuring the stability of the packaging carton lid 2 after fastening. It allows for quick sealing of the packaging carton and is reusable, making it convenient to operate.

[0038] Specifically, each of the four corners of the packaging carton body 1 is fixedly provided with a reinforcing side brace 3, and the connecting piece 4 is fixedly connected to the reinforcing side brace 3. A guide rod 16 is fixedly provided on the reinforcing side brace 3. It should be noted that the guide rod 16 can guide the connecting cloth strip 13, and the reinforcing side brace 3 can reinforce the corners of the packaging carton body 1.

[0039] Specifically, a baffle 12 is fixedly sleeved on the outside of the upright 5, and the bottom of the baffle 12 contacts the connector 4. It should be noted that the upright 5 can be limited.

[0040] Specifically, the top of the connector 4 has multiple sliding holes, and the upright 5 is vertically slidably installed in the sliding holes. It should be noted that this allows the upright 5 to move stably in the vertical direction.

[0041] Specifically, the bracket 8 is located between the two connecting blocks 10 and above the upright 5. It should be noted that the position of the bracket 8 is limited.

[0042] Working principle:

[0043] S1: When sealing the packaging carton, first attach the packaging carton cover 2 to the top of the packaging carton body 1 to ensure that the two are properly aligned. At this time, the sealing mechanism begins to function: pull down the connecting strip 13 to move the bottom plate 6 and the upright 5 down synchronously. The upright 5 slides vertically in the sliding hole of the connector 4. The spring 7 between the bottom plate 6 and the connector 4 is stretched. As the upright 5 moves down, the rotating rod 9, the connecting block 10 and the fastening rod 11 also descend. At this time, the fastening rod 11 can be rotated. By using the rotation characteristics of the rotating rod 9 on the upright 5, the fastening rod 11 can be adjusted to be directly below the hanger 8.

[0044] S2: After the connecting strip 13 is released, the spring 7 retracts due to elastic recovery, causing the base plate 6 and the upright 5 to move upward. The fastening rod 11 rises accordingly and abuts against the inside of the hanger 8. The spring 7 continues to apply upward elastic force, so that the fastening rod 11 presses tightly against the hanger 8. The hanger 8 firmly presses the carton cover 2 onto the carton body 1, completing the initial sealing. To further reinforce, the connecting strip 13 is bypassed by the guide rod 16 on the reinforcing side support 3. The guide rod 16 serves as a guide and limiter to prevent the connecting strip 13 from shifting. The Velcro 14 on the connecting strip 13 is glued and fixed to the Velcro 2 15 on the connector 4. The adhesiveness of the Velcro further restricts the displacement of the base plate 6 and the upright 5, ensuring that the abutment state between the fastening rod 11 and the hanger 8 is stable, achieving complete sealing of the carton. At the same time, the reinforcing side supports 3 at the four corners of the carton body 1 enhance the overall structural stability and prevent the carton from deforming during sealing.

[0045] S3: When the packaging carton needs to be opened, first tear off the Velcro 14 on the connecting strip 13 to release the Velcro from the connecting strip 13. At this time, the spring 7 is released, pushing the base plate 6 and the upright 5 back to their original positions. The baffle 12 on the outside of the upright 5 contacts the connector 4, limiting the upright 5 from moving too high. Then rotate the fastening rod 11 to disengage it from the contact state with the hanger 8. Lift the packaging carton cover 2 upwards to open the carton. The whole process does not require the use of tape. All sealing components can be reused. The elasticity of the spring 7 ensures the stability of the fastening. The Velcro is easy to stick and separate. The sliding of the upright 5 and the rotation of the rotating rod 9 reduce the difficulty of operation and realize the function of quick sealing and opening.

[0046] The present invention provides a detailed description of a convenient packaging carton. Specific embodiments have been used to illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
