Description

Capable of clamping thick article pen clip

Technical field

The utility model relates to the lip pencil articles for use, especially a kind of capable of clamping thick article pen clip that is used on the lip pencil articles for use.

Background technology

Pen clip is the part of lip pencil articles for use, and said lip pencil articles for use are meant a class such as ball pen, pen, propelling pencil, signature pen and products such as pen type opaquing fluid and test pencil.The lip pencil articles for use are clamped on other article by pen clip, as are clamped on the pocket or on the notebook, are easy to carry.Existing lip pencil articles for use, its pen clip are generally with the main body of lip pencil articles for use fixedlys connected, i.e. pen clip and main body or be one, and perhaps both are rigidly connected.The pen clip of this structure, the scope of activities of pen clip is less, and the strain that only can utilize pen clip itself is held on the lip pencil articles for use on the thin object, as is held on the cloth of pocket or is held on a few Zhang Putong writing papers.If with the thicker object of common pen clip clamping, exceed the elastic range of pen clip itself, just can't clamping, even cause the pen clip damage.

Summary of the invention

The purpose of this utility model is at existing lip pencil articles for use, its pen clip and lip pencil articles for use main body are for fixedlying connected, only can utilize the strain of pen clip itself that the lip pencil articles for use are held on the thin object, if just can't clamping with the thicker object of common pen clip clamping, even the problem that causes pen clip to be damaged, but provide a kind of clamping thick thing, easy to use, simply constructed capable of clamping thick article pen clip.

Capable of clamping thick article pen clip described in the utility model comprises main body, pen clip, flexible member, lip pencil articles for use main body lug, pen clip lug and the little axle of lip pencil articles for use.Be equipped with aperture on lip pencil articles for use main body lug and the pen clip lug.Little axle is loaded in the aperture.Pen clip is connected with lip pencil articles for use main body by little axle.Be equipped with on the little axle and make pen clip be pressed together on flexible member on the lip pencil articles for use main body all the time.

Lip pencil articles for use main body lug is two, and the pen clip lug also is two.Pen clip lug and lip pencil articles for use main body lug cooperatively interact.

Flexible member can be torsion spring or plate shape spring.

Pen clip can be metal or plastics.

The little axle that connects pen clip and lip pencil articles for use main body can be a rivet.

The capable of clamping thick article pen clip of the utility model can be used on the series products, on stationery series products such as ball pen, gel ink pen, pen, propelling pencil, signature pen, e-Pointer, marking pen, pen type opaquing fluid, also can be used on other products with class profile, as products such as test pencils.

The utility model has the advantages that to be clamped on the thicker object that easy to use, clamping is reliable, simple structure.

The specific embodiment

As shown in Figure 1-Figure 3, capable of clamping thick article pen clip described in the utility model comprises main body 5, pen clip 7, torsion spring 1, lip pencil articles for use main body lug 2, pen clip lug 3 and the rivet 6 of lip pencil articles for use.Be equipped with aperture 4 on lip pencil articles for use main body lug 2 and the pen clip lug 3.Rivet 6 is loaded in the aperture 4.Pen clip 7 is connected with lip pencil articles for use main body 5 by rivet 6.Be equipped with on the rivet 6 and make pen clip be pressed together on torsion spring 1 on the lip pencil articles for use main body 5 all the time.

Capable of clamping thick article pen clip described in the utility model, pen clip 7 separates with lip pencil articles for use main body 5, connects together by rivet 6 with torsion spring 1 between the two, and torsion spring 1 produces the opposite elastic force of direction to pen clip 7 and lip pencil articles for use main body 5 respectively.In fact, because pen clip 7 combines by rivet 6 with a class article, pen clip 7 parts become a lever, and rivet 6 is exactly a fulcrum.According to the principle of lever, when pressing the top of pen clip 7, because the L1 size is much smaller than the L2 size, therefore, the distance H 2 that rise pen clip 7 bottoms is much larger than the distance H 1 that presses down on pen clip 7 tops.Therefore, when pen clip 7 tops pressed down, the open distance in pen clip 7 bottoms can comprise thicker object.Because the effect of torsion spring 1, when loosening pen clip 7 tops, pen clip 7 bottoms will clamp, thereby clamp thick thing.

Torsion spring 1 working strength height, the metal material that elasticity is big are made.Rivet 6 uses the metal material that is easy to punching press to make.Main body 5 pen clips 7 are respectively equipped with two leg-of-mutton lugs 2,3.Going up of lug 2,3 aperture 4 respectively coaxial, same diameter by one.Distance between 3 liang of holes of pen clip lug is greater than the distance between the outside, 2 liang of holes of main body lug, and like this, pen clip 7 is when four apertures on the main body 5 align, inside pen clip 7 upper lug 3 are included in the lug on the main body 5.The internal diameter of torsion spring 1 is greater than or equal to the diameter of four apertures 4 on pen clip 7, the main body 5.Then less than the diameter of four apertures 4 on pen clip 7, the main body 5, length is greater than the distance in 7 liang of aperture 4 outsides of pen clip for the diameter of rivet 6.When four apertures 4 on pen clip 7 and the main body 5 and torsion spring 1 co-axially align, rivet 6 is inserted in the center in these several holes, these several parts are coupled together.After the connection, with the thin end of rivet 6 with rivet driver towards riveting, make rivet 6 from the hole, not deviate from, but guarantee that pen clip 7 rotates along rivet 6.Two ends of torsion spring 1 have respectively and the torsion spring one, long straight section.Owing to after two straight section angles of torsion spring 1 greater than main body 5 and the angle that pen clip 7 forms, make that torsion spring 1 is packed into, be in compressive state, make pen clip 7 lower ends tightly be pressed on the main body 5.

As can be seen, in fact, pen clip 7 becomes lever after being fixed on the rivet 6.Rivet 6 is the fulcrum of lever.Therefore, this lever satisfies L1 Δ H2=L2 Δ H1 (Δ H1, Δ H2 are respectively the distance that move at the lever two ends).When press from pen clip 7 upper ends Δ H1 apart from the time, the distance, delta H2=L2 Δ H1/L1 that pen clip 7 lower ends then are lifted.Because the distance of L2 is approximately 4～6 times of L1 distance in actual product, therefore, when pen clip 7 upper ends were pressed 2mm, the distance that pen clip 7 lower ends are lifted was approximately 8～12mm, and like this, the lower end of pen clip can hold the thick thing of 8～12mm.Because torsion spring 1 adopts elasticity preferred metal material, when giving pen clip 7 upper end pressing forces, make pen clip 7 upper ends move the distance of Δ H1 to main body 5, torsion spring 1 is compressed simultaneously, and the elastic force that makes torsion spring 1 give pen clip 7 strengthens, and is same because the principle of lever, after if thicker object is clamped in pen clip 7 lower ends, after cancelling the pressing force of pen clip upper end,, make pen clip 7 lower ends be clamped in securely on the thick thing because elastic force still exists and amid a sharp increase when more not pressing from both sides any object.
