Description

Technical Field

[0001] This utility model relates to the field of frozen food processing equipment, and in particular to a structure for a frozen chicken plastic box with an automatic sealing function. Background Technology

[0002] In the frozen food packaging industry, plastic boxes for frozen chicken serve as an important packaging medium, playing a crucial role in protecting the quality of frozen chicken, preventing moisture loss, and facilitating transportation and storage. The rationality and functionality of their structural design directly affect the quality and safety of the frozen chicken during freezing and distribution, as well as its ease of use.

[0003] Existing frozen chicken plastic containers typically consist of a box body and a sealing lid, usually connected by a snap-fit ​​structure. Specifically, the sealing lid has a groove on its edge, and a corresponding movable latch on the box body secures the lid to the box body through the engagement of the latch and the groove. During the freezing process, excess moisture from the frozen chicken accumulates inside the plastic container. Some containers have a filter at the bottom to remove impurities, and the accumulated moisture is stored at the bottom of the container. When the frozen chicken needs to be retrieved, the user must manually open the sealing lid, remove the chicken, and remove any excess moisture.

[0004] However, existing plastic containers for frozen chicken have significant drawbacks in practical use. First, the snap-fit ​​connection between the sealing lid and the container body lacks an automatic sealing function. Closing the lid requires precise manual operation to ensure the latch is fully engaged, a cumbersome process that is prone to leaks due to improper handling, affecting the freezing and preservation of the chicken. Second, the existing structure cannot effectively and efficiently drain excess moisture from the container. When removing the frozen chicken, excess moisture easily spills, causing inconvenience and potentially contaminating the work environment or other items. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a frozen chicken plastic box structure with automatic sealing function, aiming to improve the problem of inefficient and convenient drainage in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a frozen chicken plastic box structure with automatic sealing function, comprising a box body, a sealing cover provided on the top of the box body, insert plates fixedly connected to the bottom left and right sides of the sealing cover, slots provided inside the insert plates, shells fixedly connected to the left and right sides of the box body, two springs fixedly connected to the bottom of the shell, a fixing block fixedly connected to the top of one of the springs, a rotating shaft fixedly connected to the middle of the shell, a locking pin rotatably connected to the outside of the rotating shaft, the top of the other spring fixedly connected to the bottom of the locking pin, and a pressing plate slidably connected to the inner side of the shell.

[0007] As a further description of the above technical solution:

[0029] 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.

[0030] Reference Figures 1-3This utility model provides an embodiment of a frozen chicken plastic box structure with an automatic sealing function, comprising a box body 1, which is used to hold frozen chicken and serves as the basic load-bearing component of the entire plastic box. A sealing cover 2 is provided on the top of the box body 1 to seal the box body 1, preventing the frozen chicken from being contaminated by external factors during storage or transportation, and reducing moisture evaporation. Insert plates 3 are fixedly connected to the left and right sides of the bottom of the sealing cover 2. The insert plates 3 cooperate with corresponding structures on the box body 1 to achieve a connection and fixation between the sealing cover 2 and the box body 1. A slot 4 is provided inside the insert plate 3, which is used to engage with a locking pin 9, thereby locking the sealing cover 2. A shell 5 is fixedly connected to the left and right sides of the box body 1. The shell 5 provides installation space for internal components such as springs 6 and locking pins 9, and serves to protect and support the internal structure. Two springs 6 are fixedly connected to the bottom of the shell 5. The springs 6 provide a restoring force to the locking pins 9, ensuring that the locking pins 9 remain engaged with the slots 4 when no external force is applied, ensuring that the sealing cover 2 is securely locked. One of the springs 6 has a fixed block 7 fixedly connected to its top end. The fixed block 7 restricts the deformation direction of the spring 6, ensuring the stability of the spring force. A rotating shaft 8 is fixedly connected to the middle of the housing 5. The rotating shaft 8 serves as the fulcrum for the rotation of the locking pin 9, allowing the locking pin 9 to rotate around it and engage or disengage with the slot 4. The locking pin 9 is rotatably connected to the outside of the rotating shaft 8. The locking pin 9 locks and unlocks the sealing cover 2 by engaging or disengaging with the slot 4. The top end of another spring 6 is fixedly connected to the bottom of the locking pin 9. This spring 6 assists the locking pin 9 in resetting and also acts as a buffer during the rotation of the locking pin 9. A pressing plate 10 is slidably connected to the inside of the housing 5. The pressing plate 10 is used to press against the locking pin 9 when the sealing cover 2 needs to be opened, causing the locking pin 9 to rotate and release the engagement with the slot 4. The locking pin 9 and the slot 4 engage in an automatic locking manner to prevent the sealing cover 2 from being opened accidentally. The insert plate 3 is slidably connected inside the housing 5 and positioned above the fixing block 7. This structural design allows the insert plate 3 to slide smoothly during the installation and removal of the sealing cover 2. The pressing plate 10 is slidably connected above the locking pin 9. The pressing plate 10 is positioned between the housing 5 and the sealing cover 2, allowing the operator to trigger the rotation of the locking pin 9 by pressing the pressing plate 10.

[0031] Reference Figures 2-3A filter screen 11 is fixedly connected inside the housing 1. The filter screen 11 is used to separate excess water from the frozen chicken, allowing the water to flow smoothly and preventing water accumulation around the frozen chicken from affecting its quality. A sliding hole 12 is provided on the right side of the housing 1, providing an installation channel and sliding space for the U-shaped tube 13. The U-shaped tube 13 is slidably connected inside the sliding hole 12, and the U-shaped tube 13 is used to discharge the filtered water out of the housing 1, facilitating cleaning and water collection. A ball 14 is fixedly connected to the front of the U-shaped tube 13. The ball 14 cooperates with the gripping cap 15 to fix the U-shaped tube 13 when not draining water, preventing accidental water leakage. The gripping cap 15 is fitted on the outside of the ball 14, and the gripping cap 15 engages with the ball 14 to fix the position of the U-shaped tube 13, while also facilitating release when drainage is needed. The ball 14 is located at the bottom of the filter screen 11, ensuring that water can flow smoothly into the U-shaped tube 13. The gripping cap 15 is fixedly connected to the right side of the box body 1, providing support for the snap-fit ​​fixing of the U-shaped tube 13. When freezing is required, pressing the pressing plate 10 causes it to press against the locking pin 9. Due to the action of the rotating shaft 8, the locking pin 9 tilts backward, releasing the latch and successfully pulling the sealing cover 2 out of the box body 1. This operation method is simple and convenient, allowing operators to easily place frozen chicken into the box body 1 before freezing. Excess moisture from the frozen chicken will eventually flow into the bottom storage or out through the filter screen 11, effectively removing excess moisture from the frozen chicken and ensuring the freezing effect and quality. When it is necessary to remove the chicken, simply pull the U-shaped tube 13 to release the snap-fit ​​between the ball 14 and the gripping cap 15, and excess moisture can be easily drained. The operation is convenient and facilitates cleaning the moisture inside the box body 1. After placing the frozen chicken in, simply press the sealing cover 2. Due to the action of the spring 6, the locking pin 9 will automatically lock into the slot 4, completing the self-locking process and achieving automatic locking of the sealing cover 2 without additional operation, improving ease of use. While locking, the press plate 10 also facilitates lifting and placing. When the sealing cover 2 is locked, the press plate 10 can be used as a handle to facilitate the handling of the plastic box.

[0032] Working principle: When freezing is required, press the pressure plate 10 to block the locking pin 9. Due to the action of the rotating shaft 8, the locking pin 9 will tilt backward, releasing the latch and successfully pulling the sealing cover 2 out of the box body 1. Excess moisture from the frozen chicken will flow into the bottom storage or out through the filter screen 11. When it is necessary to remove the chicken, simply pull the U-shaped tube 13 to release the latch between the ball 14 and the gripping cap 15, allowing excess moisture to be drained smoothly. After placing the frozen chicken in, simply press the sealing cover 2. Due to the action of the spring 6, the locking pin 9 will automatically lock into the slot 4, completing the self-locking process. At the same time, pressing the pressure plate 10 also facilitates lifting and placing.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
