Description

A stationery box that can be opened and closed bidirectionally

technical field

The utility model relates to the technical field of stationery box structure, in particular to a stationery box which can be opened and closed bidirectionally.

Background technique

At present, the stationery boxes used by primary and middle school students on the market have the disadvantage that they cannot be opened in reverse, that is, the stationery boxes can only be opened in one direction, and cannot be opened in both directions, which is inconvenient in use.

Contents of the invention

The technical problem to be solved by the utility model is to provide a writing case that can be opened and closed bidirectionally, which simply and effectively solves the technical problem of bidirectional opening and closing.

In order to solve the above technical problems, the utility model provides a stationery box that can be opened and closed in both directions, including a box body and a box cover. At least one left connecting rod and one right connecting rod are used to move between the box body and the box cover. Connect, the front end of the left connecting rod is hinged with the front side of the box cover, and the rear end is hinged with the rear side of the box body; the rear end of the right connecting rod is hinged with the rear side of the box cover, and the front end is hinged with the front side of the box body.

In the above-mentioned technical scheme, since at least one left connecting rod and one right connecting rod are movably connected between the box body and the box cover, the front end of the left connecting rod is hinged with the front side of the box cover, and the rear end is hinged with the rear side of the box body; The rear end of the connecting rod is hinged with the rear side of the box cover, and the front end is hinged with the front side of the box body. With this cover structure, when the closed box cover is opened backward relative to the box body, the box cover is connected to the box body with the rear end of the left connecting rod. The rear hinge and the right connecting rod and the rear hinge of the box cover are the fulcrums for right rotation. At this time, the right connecting rod is close to the box body and remains still, and the left connecting rod is close to the box cover and rotates together with the box cover. ; when the closed lid is opened forward relative to the box body, the lid is rotated forward with the front hinge of the right connecting rod and the front hinge of the box body and the hinge of the left connecting rod and the front of the lid. At this time, the left The connecting rod is close to the box body and remains motionless, and the right connecting rod is close to the lid and rotates left together with the lid; the process of closing the pencil case is just the opposite. Like this, just can realize and solve the technical problem of front and back two-way opening and closing, reach the effect of being easy to use, can open front and back arbitrarily, have simple and effective, the advantage that is not restricted by placement position.

Further, it is defined that the left connecting rod and the right connecting rod are respectively two, and the left connecting rod and the right connecting rod are equal in length, and when the lid and the box body are closed, the left connecting rod and the right connecting rod are arranged in parallel. Limit the equal length of the left connecting rod and the right connecting rod. When the lid and the box body are closed, the left connecting rod and the right connecting rod are arranged in parallel. Such a restrictive design ensures that the left and right connecting rods in the double-open pencil case The symmetry setting makes the front and rear open and close with the same strength.

All in all, compared with the original structural design, the pencil case of this technical solution can simply and effectively solve the technical problem of bidirectional opening and closing at the front and back, and achieve the effect of being easy to use, and the box cover can be opened back and forth arbitrarily. Location restrictions.

Detailed ways

Below in conjunction with accompanying drawing and technical scheme of the utility model is further described:

Embodiment 1 of a stationery box that can be opened and closed bidirectionally in the front and back of the utility model. This stationery box that can be opened and closed in both directions in the front and back, as shown in Fig. 1, Fig. A left connecting rod 3 and a right connecting rod 4 are flexibly connected between the body 1 and the box cover 2, the left connecting rod 3 and the right connecting rod 4 are equal in length, and the front end of the left connecting rod 3 is hinged with the front side A of the box cover. , the left connecting rod 3 rear end is hinged with the box body rear side B; the right connecting rod 4 rear end is hinged with the lid 2 rear side C, and the right connecting rod 4 front ends are hinged with the box body 1 front side D. When the box cover 2 is opened backward relative to the box cover 1 frame as shown in Figure 1, the box cover 2 is connected to the hinge (B) at the rear end of the left connecting rod 3 and the rear side of the box body 1 and the right connecting rod 4 and the box. The rear hinge of the cover 2 (at C) is the fulcrum for left and right rotation.
