Loose-leaf binder capable of realizing opening function through button

Abstract

The invention discloses a loose-leaf binder capable of realizing an opening function through a button. The loose-leaf binder comprises a slim plate, hinged plates, rings, the button, bosses and lever structures. The lever structures are respectively arranged on lever plates and between the button and the bosses at both sides. According to the loose-leaf binder disclosed by the invention, as long as the button is pressed only by one finger, the loose-leaf binder can be opened. The loose-leaf binder is flexible in operation and convenient to use. As an external control structure only needs to highlight the button arranged at the middle part of the slim plate, both ends of the slim plate can be designed to be a closed structure; when the loose-leaf binder is installed in a loose-leaf notebook, gapless or micro-gap installation is realized between the loose-leaf binder and the upper end and the lower end of the cover of the loose-leaf notebook, and therefore, not only is the orderliness effect achieved but also the effects that materials are saved and the production cost is reduced are achieved. The loose-leaf binder is simple in structure and very practical.

Description

technical field [0001] The invention relates to a loose-leaf stationery folder, in particular to a loose-leaf folder which can be opened by a button. Background technique [0002] Binders are an important part of loose-leaf books. Refer to the invention patent with the patent number CN1847027A (hereinafter referred to as: reference document 1), which discloses a "ring binder mechanism". [0003] The basic structure of the binder is roughly the same as reference document 1 (see "Instructions" and "Appendix" of reference document 1). Figure 1-5 ”) mechanism 30, including an elongated plate, three rings consisting of six semicircular elements, hinged plates and control structure (the control structure is described in Reference 1 figure 1 and Figure 5 The middle mark number is "38"). [0004] In the prior art, it is necessary to set a control structure (such as the control structure 38 in Reference 1) at both ends or one end of the slender board. When opening the loose-lea...
