DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Embodiment 1: please refer to Figures 1-7 The utility model provides a technical scheme: a storage device for engineering cost list, including the box body 1, the box body 1 top is connected with the cover plate 2, the cover plate 2 one side is provided with the buckle 3, still including the storage box 4, the storage box 4 is located in the box body 1 inside, and the storage box 4 one side is connected with the stretch open and close structure 5, and the storage box 4 is connected with the box body 1 through the stretch open and close structure 5.

[0024] Firstly, the cover plate 2 is opened through the buckle 3, then the rotating movement of the stretch open and close structure 5 is driven by rotating the stretching piece 6, the storage box 4 is rotated to expose the opening of the storage box 4, and the inclined bottom of the storage box 4 can place the files in the storage box 4 in a staggered manner, so that the subsequent searching and taking of the files are facilitated.

[0025] The stretch open and close structure 5 includes a fixed plate 51, the fixed plate 51 is fixedly connected to one side of the storage box 4, one side of the fixed plate 51 is connected with a rotating shaft one 52, the rotating shaft one 52 is rotatably connected with the inner wall of the box body 1, one side of the fixed plate 51 is rotatably connected with a rotating plate 53, one side of the rotating plate 53 is connected with a rotating shaft two 54, one end of the rotating shaft two 54 is connected with a pull rod 55, and one side of the pull rod 55 is connected with the stretching piece 6.

[0026] Firstly, the pull rod 55 is rotated under the prying of the lever 61, and the rotating of the rotating plate 53 is driven, the rotating of the rotating rod pulls the rotating of the fixed plate 51, thereby driving the rotating of the storage box 4, so that the effect of rotating the opening is achieved, and the inclined bottom of the storage box 4 can place the files in the storage box 4 in a staggered manner, so that the subsequent searching and taking of the files are facilitated.

[0027] The stretching piece 6 includes a lever 61, the lever 61 is connected to one side of the pull rod 55, one end of the lever 61 is connected with a rotating shaft three 63, the rotating shaft three 63 is rotatably connected with the inner wall of the box body 1, the lever 61 is connected with a stretching plate 62, the stretching plate 62 is wrapped outside the lever 61, a sliding groove 64 is formed on the surface of the stretching plate 62, and the sliding groove 64 is wrapped outside the rotating shaft three 63.

[0028] Firstly, the stretching plate 62 is pulled out, the stretching plate 62 is slid outside the lever 61, the protruding block of the sliding groove 64 is clamped on one side of the rotating shaft three 63 to play a role of fixing and limiting, because the rotating shaft three 63 is installed on one side of the inner wall of the box body 1, so that the lever principle is formed after the stretching plate 62 is pulled out, thereby finding that the stretching piece 6 can drive the rotating of the stretch open and close structure 5.

[0029] Working principle: First, pull out the stretching plate 62 and fix it on the rotating shaft 63 at one end of the lever 61. Then, rotate the lever 61 to drive the pull rod 55 to rotate. The pull rod 55 rotates under the prying of the lever 61, which in turn drives the rotating plate 53 to rotate. The rotation of the rotating rod pulls the fixed plate 51 to rotate, thereby driving the storage box 4 to rotate, achieving the effect of rotating the opening. At the same time, the tilted bottom of the storage box 4 allows the documents inside the storage box 4 to be placed in a staggered manner, making it convenient to find and retrieve documents later.

[0030] Example 2: Please refer to Figures 1-7 Based on Embodiment 1, this utility model provides a technical solution: a storage device for engineering cost list, including a storage box 4 configured as a parallelogram.

[0031] This allows for a tighter fit between storage boxes 4, and the sloping bottom of storage box 4 allows for staggered placement of documents inside, making them easier to find later.

[0032] The tension plate 62 has a groove inside, which allows the tension plate 62 to slide on the outside of the lever 61.

[0033] A stretch plate 62 is provided on the outside of the lever 61. The stretch plate 62 can be pulled out when in use and pushed inward when not in use, reducing the space occupied and facilitating the closing of the cover plate 2.

[0034] The sliding groove 64 is rectangular and has a semi-circular protrusion on one side.

[0035] After the stretching plate 62 is pulled to the position of the rotating shaft 63, the semi-circular protrusion can be locked on the protrusion, so that the stretching plate 62 can be fixed on the outside of the lever 61, which plays the role of fixing and limiting the stretching plate 62.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
