Problems solved by technology

The disadvantages of the clamping device of the above-mentioned half-ring fastening are: the control device is more complicated; the joint of the half-ring is exposed, which affects the overall aesthetics; The operator is easily pinched, and the ring edge is not smooth, so that the operator may be cut by the edge of the half ring during the operation of replacing the document or turning the document over
The disadvantage is that the shape and structure of the ring body is complex, which is not conducive to processing and production. The limit groove is set separately from the built-in slideway for ring rotation, which is inconvenient to use and not beautiful, and the reliability of the ring opening and closing state is poor.

Embodiment Construction

[0030] The technical solutions of the present invention will be further described in detail below through embodiments in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the clamping mechanism of the present invention is used in a binder, and the binder is used to fix loose-leaf paper and other thin-layer objects, such as perforated paper, in folders or notebooks, so as to realize the filling of a certain amount of loose-leaf paper and other thin-layer objects. Add, extract and fix. The loose-leaf folder 100 shown in the figure is a commonly used style, and its shell includes an upper plate 104, a lower plate 102 and a spine 106, and a clamping mechanism 300 is fixed on the inside of the spine 106, and its fixed connection method can adopt the prior art, such as adopting way of fixing with rivets. Such as figure 2 , 3 , 4, and 5, a clamping device 200 for the above-mentioned binder consists of a connecting plate 300, a first ring 402L, a sec...

Abstract

A clamping device used for a flange clip comprises at least one connection plate of a holding cavity, at least one annular substance which is provided with a cut and used for arranging the thin layer substances like flange paper as well as at least one elastic mechanism arranged in the at least one holding cavity of the connection plate; the annular substance is transversely penetrated on the connection plate; the elastic mechanism is collocated to be used for contacting and pressing at least one of the annular substance that is transversely penetrated. When in use, the opening and closing of an annular mechanism can be realized only by manually rotating the annular substance. Manually rotating the annular substance is easy to operate; besides, the annular substance can firmly and sufficiently rotate; the operation is safe; the clamping device used for a flange clip has reliability and practicability. Besides, the clamping device used for a flange clip has simple structure and can realize low cost production.

Description

technical field [0001] The invention relates to a clamping device for a loose-leaf folder, in particular to a clamping device for a binder with a connecting plate and a ring mechanism for clamping and fixing a plurality of loose-leaf papers and other thin-layer objects. Background technique [0002] Binder is a kind of stationery used in daily life, which is convenient for storing files in different categories. At present, the widely used binder includes a top plate, a bottom plate and a spine, and the top plate and the bottom plate are connected by the spine, and the inner middle part of the spine has a clamping mechanism. The existing clamping devices generally have a rigid elongated plate on which multiple ring clamping devices are fixed. Multiple rings are closed and opened by a lever mechanism to secure perforated loose-leaf pages in folders or notebooks. Users can choose to open the clamping device to add or remove paper, and also can choose to fix the required loose...
