[0029] In the embodiment, in order to achieve the purpose of facilitating the carrying of the aluminium foil lunch box body 1 after the aluminium foil lunch box handle unit 3 is unfolded, when it is necessary to carry the aluminium foil lunch box body 1, the user pulls the hand-held cylinder 31 to overcome the elastic force of the spring 42 in the handle limiting component 4, and releases the hand-held cylinder 31 from the limiting state in the recess 22. Since the hand-held cylinder 31 is sleeved on the connecting rod 32 and can slide, and the connecting arm one 33 and the pivot one 34, and the connecting arm two 35 and the pivot two 36 are connected through bearings, the user can pull the hand-held cylinder 31 to drive the connecting rod 32 to move outward, and the connecting arm one 33 and the connecting arm two 35 rotate and unfold around the pivot one 34 and the pivot two 36 until the handle is in a horizontal state. At this time, the user can hold the hand-held cylinder 31 to conveniently carry the aluminium foil lunch box body 1, avoiding directly touching the lunch box filled with hot food and being scalded by the lunch box;
[0030] In order to realize the purpose that the aluminum foil lunch box handle unit 3 can be unfolded or folded, the device adopts the following technical scheme: the hand holding barrel 31 is sleeved outside the connecting rod 32 and is in sliding connection with the connecting rod 32, the rotating shaft one 34 penetrates through the connecting arm one 33 and is connected with the connecting arm one 33 through a bearing, one end of the rotating shaft two 36 extends into the side wall of the groove 22 and is connected with the side wall of the groove 22 through a bearing, when the handle is not needed, the hand holding barrel 31 is pushed to move into the groove 22, the connecting arm one 33 and the connecting arm two 35 are gradually folded under the action of the rotating shaft one 34 and the rotating shaft two 36, until the handle is entirely stored in the groove 22, with the movement of the hand holding barrel 31 to the deep part of the groove 22, it will contact with the limiting plate 44, at this time, the hand holding barrel 31 pushes the limiting plate 44 to slide into the cavity 23, and the compression spring 42 is compressed, when the hand holding barrel 31 moves to the arc-shaped area at the end of the limiting plate 44, the spring 42 pushes the connecting plate 43 and the limiting plate 44 to reset through the elastic force, the limiting plate 44 clamps the hand holding barrel 31, and the handle is stably kept in the folded state, preventing it from being accidentally unfolded in the non-use state, and also ensuring the flatness of the top of the lunch box, facilitating stacking, storage or transportation.
[0031] In order to realize the purpose that the folded aluminum foil lunch box handle unit 3 is limited, the device adopts the following technical scheme: the fixed plate 41 is arranged inside the cavity 23 and is fixedly connected with the cavity 23, one end of the spring 42 is fixedly connected with one side wall of the fixed plate 41, the other end of the spring 42 is fixedly connected with one side wall of the connecting plate 43, the connecting plate 43 is arranged inside the cavity 23 and is in sliding connection with the cavity 23, one end of the limiting plate 44 extends into the inside of the groove 22, the limiting plate 44 is in sliding connection with the cavity 23, the fixed plate 41 in the handle limiting part 4 is fixed in the cavity 23, providing support for the spring 42, one end of the spring 42 is connected with the fixed plate 41, and the other end is connected with the connecting plate 43, the connecting plate 43 drives the limiting plate 44 to slide in the cavity 23, when the handle is unfolded, the limiting plate 44 partially extends into the groove 22 under the elastic force of the spring 42, and blocks the hand holding barrel 31 from sliding into the groove 22 at will; when the handle is folded and stored, the limiting plate 44 is limited and fixed to the hand holding barrel 31 through the interaction with the hand holding barrel 31 and under the cooperation of the spring 42, so that the handle is in a stable folded state.
[0032] The working process of the utility model is as follows: when the utility model is used, the connection mode of the aluminum foil lunch box body 1 and the aluminum foil lunch box cover assembly 2 adopts the prior art, for example, buckle type connection (a clamping groove is arranged on the edge of the lunch box, and a clamping hook is arranged on the corresponding position of the cover. When the cover is covered on the lunch box, the clamping hook will be clamped into the clamping groove, forming a tight connection. This connection mode can conveniently open and close the lunch box, and can provide certain sealing performance. It is relatively convenient to open and close, and consumers can easily operate with one hand. At the same time, after being opened and closed for many times, the connection performance can still be maintained well. As long as the buckle structure is not damaged, the sealing effect can be maintained to some extent, preventing food leakage), handle unfolding and use: when the aluminum foil lunch box body 1 needs to be carried, the user pulls the hand holding cylinder 31, overcomes the elastic force of the spring 42 in the handle limiting part 4, releases the hand holding cylinder 31 from the limiting state in the groove 22, since the hand holding cylinder 31 is sleeved on the connecting rod 32 and can slide, and the connecting arm one 33 and the connecting arm two 35 are connected through the bearings, the user pulls the hand holding cylinder 31, drives the connecting rod 32 to move outward, and the connecting arm one 33 and the connecting arm two 35 rotate and unfold around the pivot one 34 and the pivot two 36, until the handle is in a horizontal state. At this time, the user can hold the hand holding cylinder 31 and conveniently carry the aluminum foil lunch box body 1, avoiding directly contacting the lunch box containing hot food and being scalded by hand; handle folding and storage: when the handle is not needed, the hand holding cylinder 31 is pushed to move into the groove 22, the connecting arm one 33 and the connecting arm two 35 are gradually folded under the action of the pivot one 34 and the pivot two 36, until the handle is entirely stored in the groove 22. With the movement of the hand holding cylinder 31 to the deep part of the groove 22, it will contact the limiting plate 44. At this time, the hand holding cylinder 31 pushes the limiting plate 44 to slide into the cavity 23, compressing the spring 42. When the hand holding cylinder 31 moves to the arc area at the end of the limiting plate 44, the spring 42 pushes the connecting plate 43 and the limiting plate 44 to reset through the elastic force. The limiting plate 44 clamps the hand holding cylinder 31, stably maintaining the handle in the folded state, preventing accidental unfolding in the non-use state, and also ensuring the flatness of the top of the lunch box, facilitating stacking, storage or transportation; working mechanism of the limiting part: the fixed plate 41 in the handle limiting part 4 is fixed in the cavity 23, providing support for the spring 42. One end of the spring 42 is connected with the fixed plate 41, and the other end is connected with the connecting plate 43, driving the limiting plate 44 to slide in the cavity 23. When the handle is unfolded, the limiting plate 44 partially extends into the groove 22 under the elastic force of the spring 42, blocking the hand holding cylinder 31 from sliding into the groove 22 at will. When the handle is folded and stored, the limiting plate 44 is limited and fixed to the hand holding cylinder 31 through the interaction with the hand holding cylinder 31 and the cooperation of the spring 42, ensuring that the handle is in a stable folded state.
[0033] The above merely describes preferred embodiments of the present application, and any modification or equivalent substitution of the technical solutions described above can be made by those skilled in the art. Therefore, any simple modification or equivalent substitution made according to the technical solutions of the present application is within the scope of the present application.
