[0022] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0023] Embodiment 1:

[0024] This embodiment introduces a specific structure of a plastic cover with a self-locking function. Figure 1-Figure 4 As shown, it includes a plastic cover body 1 and a locking plate 2, and the locking plate 2 is arranged at the bottom of the plastic cover body 1. The bottom of the plastic cover body 1 is fixedly connected with an extension plate 3, and the bottom is extended downward and connected to the locking plate 2, and the width is consistent with the thickness of the stabilizing bar 6. Since the bottom of the extension plate 3 is fixedly connected with the locking plate 2, when the plastic cover body 1 is covered, the locking plate 2 is used to fit with the bottom of the stabilizing bar 6, and the locking plate 2 and the plastic cover body 1 are connected by the extension plate 3, and a fixing port 4 is formed in the middle, so that after the plastic cover body 1 is covered, the inside of the fixing port 4 wraps and fixes the stabilizing bar 6:

[0025] Among them, a bending strip 5 is provided on one side of the locking plate 2. When the plastic cover body 1 is pressed downward, the locking plate 2 is driven to bend by the bending strip 5 of the locking plate 2, thereby squeezing the bottom of the stabilizing strip 6 to cover it. Since the crease of the bending strip 5 bends inward, when the locking plate 2 is fitted with the bottom of the stabilizing strip 6, the bending strip 5 can only be bent in one direction, thereby wrapping the stabilizing strip 6, so that the food inside will not seep out, and the inside of the fixing port 4 is stably connected with the stabilizing strip 6, so that the fixing port 4 wraps the stabilizing strip 6, so that the top of the stabilizing strip 6 is fixed to the top of the packing box 7, so that the plastic cover body 1 covers the packing box 7, completes the sealing of the packing box 7, and does not allow the soup inside to seep out;

[0026] At the same time, a vent hole 8 is provided at the top of the fixed opening 4. When hot air is poured into the packaging box 7, there will be hot air inside and expansion will occur, so that the gas will be discharged through the vent hole 8 at the top of the fixed opening 4. Since the vent hole 8 penetrates the plastic cover body 1, the gas will discharge the internal gas through the vent hole 8, and the inside of the vent hole 8 is slidably connected with a latch rod 9, so that when not in use, the vent hole 8 is closed by the latch rod 9, so that dust will not enter the inside of the vent hole 8. Since a pulling block 10 is fixedly connected to the top of the latch rod 9, when it is necessary to exhaust air outward through the vent hole 8, the pulling block 10 is pulled upward to pull out the latch rod 9;

[0027] Furthermore, an opening plate 11 is connected to the top of the outer surface of the plastic cover body 1. When the plastic cover body 1 needs to be opened, the opening plate 11 is opened to present a passage, which directly leads to the interior of the packaging box 7, so that the opening plate 11 opens the plastic cover body 1. Since a pull-up rod 12 is fixedly connected to one side of the opening plate 11, when the opening plate 11 needs to be opened, the pull-up rod 12 is pulled. Since the pull-up rod 12 is subjected to force, the force is transmitted downward to open the opening plate 11, and a pull ring 13 is rotatably connected to the outer surface of the pull-up rod 12, so that the pull-up rod 12 is pulled by the pull ring 13 to open the opening plate 11, and the pull ring 13 is in a circular shape, so that it is easier to pull the pull-up rod 12.

[0028] By adopting the above technical solution:

[0029] According to the above design, when the packing box 7 needs to be covered, the plastic cover body 1 is aligned with the packing box 7, and then the plastic cover body 1 is pressed toward the top of the packing box 7. During the pressing process, the locking plate 2 is attached to the stabilizing bar 6 at the top of the packing box 7, and the bending bar 5 on one side of the locking plate 2 is bent inward by the squeezing force, so that the locking plate 2 moves downward, passes through the top of the stabilizing bar 6 and is attached to the bottom of the stabilizing bar 6, so that the stabilizing bar 6 enters the fixing port 4, and then wraps the stabilizing bar 6, so that the soup inside the packing box 7 will not flow out through the outlet, and the top of the stabilizing bar 6 is attached to the bottom of the plastic cover body 1, and one side is attached to the inside of the extension plate 3, so that It is wrapped all around so that the soup inside is better protected from overflowing. When hot dishes are placed inside the packing box 7, hot air will appear inside to cause expansion. By pulling out the latch rod 9 inside the air vent 8, the internal gas is discharged outward through the air vent 8, thereby ensuring that there is no danger caused by internal expansion. When it needs to be opened for eating, the pull ring 13 is pulled upward to drive the pull-up rod 12 at one end to be pulled upward. When the pull-up rod 12 is pulled upward, it drives the opening plate 11. When the opening plate 11 moves upward to open, the food inside the packing box 7 is displayed and can be eaten through the through opening, which is more convenient.

[0030] Embodiment 2:

[0031] Based on Example 1, this example introduces the specific structure of the opening plate 11. The top of the outer side of the plastic cover body 1 is connected to the opening plate 11. A pull-up rod 12 is fixedly connected to one side of the opening plate 11. A pull-up ring 13 is rotatably connected to the outer side of the pull-up rod 12. The pull-up ring 13 is in a circular shape.

[0032] The top of the outer surface of the plastic cover body 1 is connected with an opening plate 11. When the packing box 7 needs to be opened, the locking plate 2 locks the packing box 7, thereby opening the opening plate 11 to present a passage, which directly leads to the inside of the packing box 7, so that the opening plate 11 opens the plastic cover body 1, and a pull-up rod 12 is fixedly connected to one side of the opening plate 11, so that when the opening plate 11 needs to be opened, the pull-up rod 12 is pulled, so that the pull-up rod 12 is subjected to force, and since the pull-up rod 12 is fixedly connected to the bottom with the opening plate 11, the pull-up rod 12 is pulled upward, so that the force received by the pull-up rod 12 is transmitted downward, thereby opening the opening plate 11, and the pull-up rod 12 is rotatably connected to the outer surface of the pull-up rod 12, so that the pull-up rod 12 is pulled by the pull-up ring 13, so that the opening plate 11 is opened, and the pull-up ring 13 is in a circular shape, so that when the pull-up rod 12 needs to be pulled, it is only necessary to put a finger into the pull-up ring 13, so that the operation is simpler;

[0033] By adopting the above technical solution:

[0034] According to the above design, when the packing box 7 needs to be opened, since the packing box 7 is locked by the plastic cover body 1, the packing box 7 cannot be opened by opening the plastic cover body 1. Therefore, the user puts his hand in the middle of the pull ring 13 and pulls it upward. Since the bottom of the pull ring 13 is fixedly connected to the pull rod 12, the pull ring 13 drives the pull rod 12 to move upward. When the pull rod 12 moves upward, it drives the opening plate 11 fixedly connected to the bottom of the pull rod 12 to move upward, thereby pulling the opening plate 11 upward, so that the opening plate 11 is opened and separated from the plastic cover body 1, thereby a passage appears inside, and the user can use the passage to taste the food inside the packing box 7.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
