Abstract
This technology invention relates to a kind of band tooth drawing pin of push type anti-dropout, mainly includes the head of a nail, clamp, spike-tooth, spring, sliding pawl set, metal shell, push rod etc..This technology invention is mainly used in following closely the occasion of file, poster on cystosepiment, and process for using is that first nail is inserted into cystosepiment, presses the head of a nail, the set guide rail that clamp passes through in sliding pawl set glides, when clamp removes sliding pawl set, clamp is rotated clockwise, and is stuck in sliding pawl set card slot.Under the transmitting effect of power, push rod is promoted, and stretches out spike-tooth from the hole on metal shell, is stuck in cystosepiment.If extracting drawing pin, the button on head of a nail top need to be only pressed again, under spring force, clamp re-enters into sliding pawl set guide rail, moves together with push rod, extracts spike-tooth, it can be utilized again after extraction, may greatly avoid the phenomenon that nail falls off because of external factor.
Description
Technical field
This technology invention is related to a kind of drawing pin, more particularly to a kind of band tooth drawing pin of push type anti-dropout.Main application
In the occasion for following closely file, poster on cystosepiment, belong to miniature instrument preparation and applied technical field.
Background technique
Drawing pin using very extensive, can be applicable in the propaganda boards announcement board such as community, street, company, school in life,
It can also be used in outdoor poster, nail drawing file etc..Maximum problem is exactly falling off for drawing pin in use, is caused
The loss of file.When drawing pin is inserted into the loose material of material, due to the gravity of drawing pin itself, in addition external environment
Interference, such as vibration, wind-force factor, cause drawing pin easily to fall off.The loss of file is not only caused after falling off and easily causes environment
Pollution.Currently, can be used to follow closely the anti-dropout drawing pin of file without discovery in the market.
Summary of the invention
This technology invention provides a kind of band tooth drawing pin of push type anti-dropout.In view of the above-mentioned problems of the prior art,
This technology invention improves drawing pin internal structure, may greatly avoid the phenomenon that nail falls off because of external factor.
This technology invention provides a kind of band tooth drawing pin of push type anti-dropout, mainly by the head of a nail, clamp, spike-tooth, spring, sliding pawl
Set, metal shell, push rod composition.
This technology invention provide a kind of push type anti-dropout with tooth drawing pin obtain beneficial effect be: when nail poster,
When the files such as drawing, rivet nut has telescopic spike-tooth, when in use, presses the head of a nail, spike-tooth stretching is stuck in material internal, is not easy
It falls off.If extracting drawing pin, the head of a nail need to be only pressed again, and spike-tooth is withdrawn in rivet nut, and can be the case where not destroying material
It is lower easily to extract.It can be widely used in the propaganda boards announcement board such as community, street, company, school, or outdoor poster,
Follow closely drawing file etc..Push type anti-dropout drawing pin is equipped with 12 circular holes in rivet nut, and 3 holes of every row amount to four rows and are symmetrically arranged,
Spike-tooth is back hook-shaped, increases contact area and frictional force with cystosepiment, and the head of a nail is the design of push type spring, and bookbinding is facilitated to tear open
It unloads, moreover it is possible to effectively prevent the planes such as spike-tooth damage cystosepiment.
Detailed description of the invention
Fig. 1 is the three-dimensional installation diagram of a kind of push type anti-dropout being caught in cystosepiment under state with tooth drawing pin；
Fig. 2 is a kind of three-dimensional installation diagram with tooth drawing pin after extracting in cystosepiment under state of push type anti-dropout；
Fig. 3 is a kind of two-dimensional engineering graphic with tooth drawing pin of push type anti-dropout.
Specific embodiment
When needing to follow closely the files such as poster, drawing in the loose material such as cystosepiment, nail is inserted into cystosepiment, is pressed
The head of a nail, the set guide rail that clamp passes through in sliding pawl set glide, and when clamp removes sliding pawl set, clamp is rotated clockwise, and is stuck in sliding pawl
It covers in card slot.Under the transmitting effect of power, push rod is rotated and is pushed into, and is stretched out spike-tooth from the hole of rivet nut and is snapped into cystosepiment
It is interior.After use, the head of a nail is pressed again, clamp removes card slot, and under the effect of spring force, push rod drives spike-tooth to retreat,
Clamp re-enters into sliding pawl set guide rail, can easily extract nail.
The above, is only the preferred embodiment of this technology invention, and anyone skilled in the art may benefit
With the technical solution of above-mentioned elaboration equivalent technical solution is modified or is revised as to this technology invention.Therefore, foundation
Any simple modification or same displacement that the technical solution of this technology invention is carried out, it is claimed to belong to the greatest extent this technology invention
Range.
