Abstract

The invention discloses an elastic full-needle-tube ball pen head in the field of stationery. The elastic full-needle-tube ball pen head comprises a ball bead and a pen tip and is characterized in that the spring end, close to a protruding seat, in a smooth tube hole is provided with an ultra-short top thread. It is guaranteed that the front end of the spring top thread is aligned with the ball bead, and the elastic full-needle-tube ball pen head is particularly suitable for a common needle-tube type gel pen.

Description

Elastic full needle tubing ball pen head
Technical field
The present invention is the elastic full needle tubing ball pen head of a kind of field of stationery.
Background technology
Needle tube type ball pen head disclosed in China CN1243646C, CN1244458C, arranges the spring structure of complexity in plastic fastening, utilizes the straight steel wire front end of the length on helical spring to withstand ball, it is prevented that ink leakage or refluence.Between full needle tubing ball pen head projection seat, gap is big, and spring jackscrew is longer to be easily bent, it is impossible to guarantee that straight steel wire coordinates concentricity with ball, affects ball smooth rotation and produce monolateral stitching when writing.
Summary of the invention
The technical problem to be solved in the present invention is: simplify full needle tubing ball pen head structure, the jackscrew that on nib smooth pore inner spring, special extreme shortens is adopted to stablize anti-bias structure, improve spring jackscrew front end precision placed in the middle, prevent jackscrew front end from getting between ball and the crack of ball seat, be particularly suitable for common needles type gel ink pen.
The technical scheme is that elastic full needle tubing ball pen head, including ball and nib, it is characterized in that: the spring terminal near projection seat has ultrashort jackscrew in smooth pore.
The invention have the advantage that simple in construction performance is reliable, it is simple to nib coupling assembles, the short and small accurate positioning of spring jackscrew in pore, and ball rotates and ink flow is smooth and easy.
Accompanying drawing explanation
Fig. 1 is the elastic full needle tubing ball pen head structure chart of embodiment.
In figure: 1. ball；2. jackscrew；3. projection seat；4. spring；5. nib；6. pore；7. lock part.
Detailed description of the invention
With reference to shown in Fig. 1, the spring 4 in the pore 6 of nib 5 is blocked by lock part after being compressed, and jackscrew 2 front end of spring 4 withstands on ball 1, and when not writing, under elastic force effect, the spring jackscrew 2 in nib 3 pushes against ball 1 and closes nib, it is prevented that ink leakage；The dynamic ball 1 of trying hard to recommend acted on when writing on pen opens nib, and ink proper flow exports.
