CN201120816Y - Convenient easy-draw plastic thumb pin - Google Patents

Abstract

The utility model relates to a plastic drawing pin which is convenient to be used and easy to be drawn out. The plastic drawing pin is composed of a plastic pin cap (1) and a pin (2). A pin top (3) connected with the pin (2) into a whole and positioned into the plastic pin cap (1) is non-circular (to avoid sliding when being rotated transversely), and the extension of the plastic pin cap (1) is inclined outward from bottom to top (to be convenient for fingers to insert from the inclination surface); therefore the aim of not damaging the plastic drawing pin or/and paper is realized during the process of repeated use (drawing and disassembly) of the drawing pin with the plastic cap.

Description

A kind of plastics drawing pin that easily pulls out easy to use

Technical field:

The present invention relates to the structure technology of drawing pin, especially the structure technology of vinyl cover shape for hat drawing pin.

Technical background:

At present, the vinyl cover shape for hat drawing pin that people use always, with paper by the nail on the wall after, because the surface of head of a nail edge and paper is close to, when wanting that it is pulled out when unloading out, hand does not have suitable force application location, be difficult for it is extracted, if use nail or other instrument that the plastics head of a nail is chosen, can damage the structure of plastics drawing pin or/and, brought trouble to repeated use by the paper of its location.---existing plastics block drawing pin structure is as follows: it is made of the plastics head of a nail (its extension is outward-dipping from top to bottom) and nail pin, nail pin and screw top (circular) structurally be disjunctor, and, the nail pin is to be positioned in the plastics head of a nail the two the disjunctor state of the plastics head of a nail and nail pin of realizing by screw top

Summary of the invention:

The present invention's purpose is:

A kind of improvement design to above-mentioned vinyl cover shape for hat figure pin structure is structurally proposed.

The present invention is achieved in that

It is made of the plastics head of a nail and nail pin, nail pin and screw top structurally are disjunctors, and, the nail pin is to be positioned in the plastics head of a nail the two the disjunctor state of the plastics head of a nail and nail pin of realizing by screw top, it is characterized in that: the extension of the above-mentioned plastics head of a nail is outward-dipping from bottom to top, and the screw top that is positioned in the plastics head of a nail is non-circular.

The present invention's characteristics compared with the prior art:

Because the extension of vinyl cover shape for hat drawing pin is designed to outward-dipping from bottom to top contour structures shape, this just can be for the structure that solves above-mentioned vinyl cover shape for hat drawing pin not fragile plastics drawing pin in (pull out and the unload) process of repeated use or/and the paper of being located by its has all been created condition; Because the screw top at structure and nail pin disjunctor is non-circular, this just for by about reverse pull out can not make when unloading drawing pin be positioned at the screw top and the plastics head of a nail in the plastics head of a nail between the two the generation skidding created condition.

Description of drawings:

Figure has illustrated structure embodiment of the present invention.

1: the plastics head of a nail (extension is outward-dipping from bottom to top); 2: the nail pin; 3: screw top (non-circular).

The specific embodiment:

Structure of the present invention is very simple, it be prior art " vinyl cover shape for hat drawing pin " by the architecture basics of the plastics head of a nail 1 and nail pin 2 the two drawing pin that constitute of making by metal material on (nail pin 2 is to fixedly positioning in the middle of the plastics head of a nail 1), only need the outer shape of the plastics head of a nail 1 extension that will be wherein to be designed to outward-dipping from bottom to top appearance structure and get final product.---and the shape of screw top 3 is non-circular (screw top of existing plastics drawing pin generally is round), when vinyl cover shape for hat drawing pin was extracted, the plastics head of a nail 1 is difficult for and screw top 3 skids like this.

When needs are pulled out vinyl cover shape for hat drawing pin, as long as clamp the inclined plane of continuously connected fastener cap 1 with finger, firmly upwards and the left rotation and right rotation plastics head of a nail 1 can easily vinyl cover shape for hat drawing pin be extracted.

Claims (1)

1. plastics drawing pin that easily pulls out easy to use, it is made of the plastics head of a nail and nail pin (2), nail pin (2) structurally is a disjunctor with screw top, and, nail pin (2) is to be positioned in the plastics head of a nail the two the disjunctor state of the plastics head of a nail and nail pin (2) of realizing by screw top, it is characterized in that: the extension of the plastics head of a nail (1) is outward-dipping from bottom to top, and the screw top (3) that is positioned in the plastics head of a nail (1) is non-circular.
