Abstract

The utility model relates to an automatic opening stationery case which is composed of an upper shell body, a middle shell body, and a lower shell body. In the utility model, a locking device and a key device are arranged on the protrusion part of the middle shell body, which is not covered by the upper shell body. When a key is inserted into the locking device, the key device can be clamped or released through a toggle movement, and pressing sheets which are arranged on the key device are respectively pressed to seat sheets which have different functions and different shapes. When the key is pressed to move, clamping heads which are inserted into all the related devices can slide out of the grooves of the related devices, and thereby, the upper shell body can be opened, and a bottom drawer and a side drawer automatically pop out under the action of a spring. The utility model has the advantages that operation is convenient, stationery does not scatter after the stationery is locked, and the utility model has the function of theft prevention.

Description

Automatic opening stationery case

The utility model relates to a kind of self opening writing case.

Existing writing case commonly used mainly is made of box and lid, and stationery such as erasing rubber, a class, pocket knife all are placed in the same box body, seems and has no order, and is disorderly and unsystematic; There was the plumbous tape drum of a kind of multilayer to occur afterwards, the user can preserve the stationery classification, but this pencil box is because of interval various in the box, must close by switch when using different stationery, wastes time and energy, very loaded down with trivial details, and writing case at present commonly used, its box and lid multiple-use card close or the mode of magnet absorption is covered together, in case careless or when moving in the process overturning, stationery is scattered, very inconvenient.

The purpose of this utility model is to provide a kind of self opening writing case, and it both can store classifiedly stationery, and can open automatically when using, and the time spent also can not lock, even overturning accidentally can oneself not opened and stationery is scattered yet.

The purpose of this utility model is achieved in that the self opening writing case, by upper shell, middle shell, lower house constitutes, on the protuberance that middle shell is not covered by upper shell, be provided with lock uint and key device, insert in the lock uint with key, stir the action holding or discharge key device but borrow, on the key device with compressed tablets, be pressed onto respectively on the difform seat of the difference in functionality sheet, when pressing button, the dop that inserts each relevant device can be skidded off from the groove of this equipment respectively, so upper shell can be opened, end drawer and side drawer eject under spring action automatically.The utility model is easy to use, and locking back stationery can not be scattered and have anti-theft feature.

The utility model is easy to use, and is time saving and energy saving, can not open easily after sealed because of it, also have antitheft, the function of anti-false touch, even if carrying accidentally, it is underground to drop, the danger that does not also have stationery to be scattered; Have different parking spaces in the box, be convenient to the stationery classification and preserve, used drawer by button, can eject automatically.
