[0002] Many containers currently have lids, and the edges of the lids are sealed with containers through sealing rings. In order to facilitate lifting, the top of some lids is provided with a lid ear. The lid ear includes a reversible and fixed structure. The reversible lid ear is generally attached to the top surface of the lid. When lifting is needed, the lid ear needs to be manually lifted. This is not convenient for users to operate. For the fixed lid ear, the lid ear protrudes upward too much, so that multiple lids are not easy to stack. This is not conducive to production, packaging, transportation, and storage. SUMMARY

The lid ear is in the shape of a "U". The two ends of the lid ear are respectively provided with oppositely extending end shafts. The two end shafts symmetrically pass through the two side parts of the middle shell. The end shafts are rotationally connected with the side parts of the middle shell. The spring wire is fixed to the inner side of the middle shell. The spring wire includes two elastic arms. The two end shafts of the lid ear are respectively arranged on the top of the two elastic arms. The bottom of the end shaft is formed with a cutting surface part. The two elastic arms are respectively elastically abutted on the cutting surface part of the two end shafts, so that the two lid ears are in an inclined standing state.
[0006] Preferably, the spring wire is in the shape of a "U".
[0007] Preferably, the middle part of the spring wire is provided with a meander-shaped part. A screw is arranged in the meander-shaped part. The screw is fixedly connected with the top of the middle shell.
[0008] Preferably, the extension length of the cutting surface part is less than the length of the end shaft, so that the root of the end shaft is formed with a cylindrical shaft.
[0009] Preferably, the two side parts of the middle shell are provided with notches through which the end shafts pass.
[0010] Preferably, the bottom of the middle shell is fixedly provided with a bottom cover. The edge of the bottom cover is tightly connected with the edge of the bottom of the middle shell.
[0011] A lid includes a lid body and a folding ear mechanism. The middle shell is fixedly arranged on the top of the lid body.
[0012] The utility model discloses a folding ear mechanism of cover, the middle shell is fixed in the top of cover, and each cover ear is across the both sides of the middle shell, and the end shaft of the both ends of cover ear is symmetrical and passes the both sides of the middle shell, and the end shaft is rotationally fitted with the middle shell, so that the cover ear can overturn relative to the middle shell, and the bottom of end shaft is equipped with the section part, when the elastic arm is elastically abuts on the section part of two end shafts, make the cover ear be inclined and stand in the natural state, when the user needs to open the cover, just need to hold two inclined cover ears and then pull up, and the technical effect of convenient pulling is achieved, in addition, if a plurality of covers are stacked, just need to overcome the elastic force of the elastic arm, and the cover ear can be pressed down flat, thereby, the production, transportation or storage are facilitated.

[0019] The utility model will be described in more detail below in combination with the drawings and examples.
[0020] The utility model discloses a folding ear mechanism of cover, combines Figures 1 to 6 As shown in the figure, it includes middle shell 1, two cover ears 2 and elastic line 3, two cover ears 2 are symmetrically arranged on the both sides of the middle shell 1, the cover ear 2 is in the shape of "U", the both ends of the cover ear 2 are respectively provided with opposite extension end shafts 20, two end shafts 20 are symmetrically passed through the both sides of the middle shell 1, and the end shaft 20 is rotationally fitted with the side of the middle shell 1, the elastic line 3 is fixed to the inner side of the middle shell 1, the elastic line 3 includes two elastic arms 30, the two end shafts 20 of the cover ear 2 are respectively arranged on the top of the two elastic arms 30, the bottom of the end shaft 20 is formed with section part 21, and the two elastic arms 30 are respectively elastically abutted on the section part 21 of the two end shafts 20, so that the two cover ears 2 are inclined and stand.
[0021] In the above structure, the middle shell 1 is fixed to the top of the cover 5, and each cover lug 2 spans across both sides of the middle shell 1. The end shafts 20 at both ends of the cover lug 2 symmetrically pass through both sides of the middle shell 1. The end shafts 20 are rotatably engaged with the middle shell 1 so that the cover lug 2 can be flipped relative to the middle shell 1. The bottom of the end shaft 20 is provided with a cut surface 21. When the elastic arm 30 elastically abuts against the cut surface 21 of the two end shafts 20, the cover lug 2 is tilted in its natural state. When the user needs to open the cover, he only needs to clamp the two tilted cover lugs 2 and pull upwards, which has the technical effect of convenient lifting. In addition, if multiple covers are to be opened, such as... Figure 5 As shown, the items can be stacked by simply overcoming the elastic force of the elastic arm 30 and pressing the cover ear 2 downwards, which facilitates production, transportation or storage.
[0022] In this embodiment, the angle between the ear cover 2 and the cover body 5 when the ear cover is tilted can be 45°.
[0023] As a preferred embodiment, the elastic wire 3 is U-shaped. Specifically, the elastic wire 3 can be formed by bending an elastic steel wire.
[0024] To facilitate fixing the spring line 3, in this embodiment, combined with Figure 3 and Figure 4 As shown, a loop-shaped part 31 is provided in the middle of the elastic line 3, and a screw 32 is inserted through the loop-shaped part 31. The screw 32 is fixedly connected to the top of the middle shell 1.
[0025] Please see Figure 3 In this embodiment, the extension length of the cut surface 21 is less than the length of the end shaft 20, so that a cylindrical shaft 22 is formed at the root of the end shaft 20. Further, the two sides of the middle shell 1 are provided with slots 10 through which the end shaft 20 can pass. The cut surface 21 extends towards the end of the end shaft 20, and a cylindrical shaft 22 is formed at the root of the end shaft 20, which is used to rotate well with the slots 10.
[0026] In order to prevent dust and dirt, in this embodiment, a bottom cover 4 is fixed to the bottom of the middle shell 1, and the edge of the bottom cover 4 is tightly fitted with the bottom edge of the middle shell 1.
[0027] Combination Figure 1 , Figure 2 and Figure 6 As shown, this embodiment also proposes a lid, which includes a lid body 5 and the aforementioned folding lid lug mechanism, with the middle shell 1 fixed to the top of the lid body 5. In practical applications, the lid body 5 closes onto the opening of the container 6.
[0028] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement or improvement within the technical scope of the present application shall be included in the scope of the present application.
