5. In the scheme, the first box body and the second box body are both rectangular; the first chamber is a rectangle defined by two side walls, a rear wall, a top plate and a bottom plate of the first box body; the second chamber is a rectangle defined by two side walls of the second box body, a top plate, a bottom plate and a cabinet door.

The utility model discloses a theory of operation and advantage as follows:

the utility model relates to a mailbag box with expandable volume; comprises a first box body and a second box body; the inner cavity of the first box body is a first cavity, and the front part of the first box body is open; the second box body is slidably assembled in the first chamber; the inner cavity of the second box body is a second cavity, the rear part of the second box body is open, and the second cavity is communicated with the first cavity; the front part of the second box body is rotatably provided with a cabinet door; the first box body and the second box body are in sliding fit in the front and back direction through a linear guide mechanism, so that the second box body has two states of retraction and extension; when the box is retracted, the second box body is positioned in the first box body, and the volume of the mailbox is the volume of the second chamber; when the second box body extends out of the first box body, the volume of the mailbag box is the sum of the volumes of the first chamber and the second chamber.

Compared with the prior art, the utility model discloses structural design is ingenious, has broken through two box sliding fit's design that the volume of parcel case in the past received not enough of box length, width, height restriction, can adjust the length that the second box stretches out according to the big or small flexibility of parcel, and then the volume of amplification parcel case. The use of the user is facilitated, and the safety of the package is ensured.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example (b): referring to fig. 1-8, a mailer case with an expandable volume; comprises a first box body 1 and a second box body 2; the first box body 1 and the second box body 2 are both rectangular.

The inner cavity of the first box body 1 is a first cavity, and the front part of the first box body 1 is open; the second box body 2 is slidably assembled in the first chamber through the opening of the first box body 1; the first chamber is a rectangle defined by two side walls, a rear wall, a top plate and a bottom plate of the first box body 1.

The inner cavity of the second box body 2 is a second cavity, the rear part of the second box body is open, and the second cavity is communicated with the first cavity through the opening of the second box body 2. The second chamber is a rectangle defined by two side walls of the second box body 2, a top plate, a bottom plate and the cabinet door 3; in this embodiment, the volume of the second chamber is smaller than the volume of the first chamber. The front part of the second box body 2 is rotatably provided with the cabinet door 3, and the cabinet door 3 is locked with the second box body 2 in a closing state through a lock 4.

The first box body 1 and the second box body 2 are in sliding fit in the front and back direction through a linear guide mechanism, and the second box body 2 is formed to have two working states of retraction and extension.

As shown in fig. 1 to 4, in the fully retracted state, the second box 2 is located in the first box 1, and the volume of the mailer box is the volume of the second chamber.

As shown in fig. 5 to 8, in the fully extended state, the second box 2 extends forward out of the first box 1, and at this time, the volume of the mailer box is the sum of the volumes of the first chamber and the second chamber.

Wherein the volume of the mailer box is linearly adjustable by the extension of the second body 2.

Preferably, the linear guide mechanism is a slide rail 5 and a slide groove 6, which are respectively fixed on the opposite surfaces of the first box body 1 and the second box body 2. As shown in fig. 6 and 8, the two cases may be fixed inside the sidewall of the first case 1 and outside the sidewall of the second case 2, respectively.

Besides, other linear guide mechanisms with the same or similar functions can be adopted, and in some embodiments, a relatively high-cost structure such as a linear air cylinder can be selected to realize the automatic extension and retraction of the second box body 2. The slide rail 5 and the slide groove 6 are preferable in the present case, in view of economy on the one hand and reliability on the other hand.

Preferably, a handle plate 7 is convexly arranged on the front part of the top plate of the second box body 2, and the upper end of the handle plate 7 is bent backwards. The user can apply force to the second case 2 through the handle plate 7 to pull out or push back the second case 2.

Preferably, the front part of the bottom plate of the second box body 2 is provided with a roller 8 downwards. By means of the design, a user can save more labor when operating the second box body 2 to retract and extend, and meanwhile, the linear guide mechanism can be protected.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
