Holding strip structure of plastic folder

Abstract

The invention relates to a stationary structure in stationery commodities, in particular to a holding structure of a plastic folder. The holding strip structure of a plastic folder comprises a trilateral long plastic holding strip (1) of which the section has an upward opening and is of a small holding seam shape. The holding strip structure is characterized in that the part above both ends of two side edges of the trilateral along the length direction is of a circular arc shape or an beveled edge, the circular arc is 90 DEG, and the included angle of the beveled edge is 45 DEG. The technical scheme can be conveniently applied to the change and the transformation of the prior art as long as the original sharp right angle is removed, and the use of the holding strip structure has obvious effects and advantages. If books are bound in batch, the binding speed, efficiency and quality can be greatly improved, and the binding difficulty is reduced. The holding strip structure seems like easy and has small improvement, the application range is wide, the accumulated social benefit is great, and the binding speed, efficiency and quality are greatly improved.

Description

(1) Technical field [0001] The invention relates to a stationery structure in stationery, in particular to a clamp structure of a plastic folder. (2) Background technology [0002] In modern life, the most commonly used method in file compilation and binding is to use a computer printer to print multi-page files, such as A4 paper-sized file pages, and then arrange them neatly, sandwich them into transparent plastic folder pages folded in half, and then use a cross-section It is an open triangular long clip strip, and the plastic clip is inserted into the edge of the opening to complete the binding. The cross-section is originally an N-shaped opening upwards. Since the clamping strip is also a plastic injection-molded part, there is no horizontal support on the top, and the two sides naturally shrink inward to form a triangle. When the long clamping strip is embedded in the plastic folder page, the two The sides of the shrinking sides are shrunk and clamped tightly to hold t...

Problems solved by technology

But still find that there is a fly in the ointment in the binding process, that is, the clamping method of the prior art is when the plastic folder page is inserted into the gap between the strip clamps, because the gap is very small, the folder page cannot be whole. Clamping together, the folder page can only be squeezed in from one end of the clamping bar, and then the folder page is pushed to the other end along the crack to complete the clamping. The two ends of the clamping bar structure in the prior art are A plane completely perpendicular to the length direction of the clamping strip, so that the ends of the two sides of the clamping strip section are sharp right angles. This right angle of the clamping strip will not have any adverse effects in use after binding. However, at the beginning of binding, when the plastic It is very difficult to insert the folder page into the gap between the long clips. The left and right sides are joined together at right angles, and the spacing is extremely small. It is extremely difficult for the plastic folder page to be inserted into the gap between the long clips. Even if it is inserted, When pushing the entire clip to the other end, it is easy to let the sharp right angle of the clip strip puncture the transparent plastic sheet clip page as the cover. Therefore, it is necessary to further improve the structure of the long clip
