Abstract

The utility model provides a double-nib fountain pen for thick and thin two purposes. The utility model is characterized in that an outer pen nib, an inner pen nib, an outer pen tongue, a guiding screw rod, a regulating rod, a guiding key and a connection pipe transmission part are added. The regulating rod is twisted along an axial direction to drive the outer pen tongue, the inner pen tongue, and the inner pen nib which are connected with the regulating rod, to move correspondingly to the outer pen nib, and radial directions are kept consistent. When the inner pen nib extends, thin fonts are written; when the inner pen nib retracts and the outer pen nib is used, thick fonts are written, and the thickness of writing order traces is different. The utility model has the advantages of simple and reasonable structure, low manufacture cost, strong applicability, convenient use and portability.

Description

The two sharp fountain pens of both thick and thin

The utility model relates to a kind of writing and uses fountain pen, the two sharp fountain pens of particularly a kind of both thick and thin, pen nib and outer pen nib intercropping relatively moved and stretch out and shrink back in it not only can make, and can be implemented in a pen and submit a written statement to a higher authority and write out two kinds of fonts that thickness is different.

Existing fountain pen kind is a lot, but most fountain pen is by pen nib, proposition, the following shaft of a writing brush, the cap for brush, capsule, leaf spring, siphon pipe, pen hanging, snap-fastener, the last shaft of a writing brush is formed, every kind of pen has only a pen nib in these fountain pens, so the thickness of handwriting is certain, want the thickness of conversion writing, have to change a fountain pen in addition and just can gather effect, but the thickness that in real work, often needs the conversion writing, need be with the thin pen of writing as accounting in when book keeping operation, and need during writing of Chinese characters with the rough pen of writing, so existing fountain pen, on one-pen, can not write out the writing of two kinds of different thicknesses, and carry many pens, very inconvenient again.

The purpose of this utility model will provide a kind of both thick and thin two sharp fountain pens exactly, the external pen nib of pen nib relatively moved and stretches out, shrinks back in it not only can make, the relative position of conversion thickness nib is write, and can be on a fountain pen, write out two kinds of fonts that thickness is different, use easy to carry.

Task of the present utility model is that following mode is finished, this utility model is by outer pen nib, interior pen nib, outer proposition, interior proposition, the following shaft of a writing brush, siphon pipe, the cap for brush, positioning retainer ring, tube connector, adjusting lever, leaf spring, the last shaft of a writing brush, capsule, guide spiro rod, feather key, pen hanging, snap-fastener is formed, to introduce the concrete shape and the structure of part in addition improving and increase in the two sharp fountain pens of both thick and thin below in detail, the following shaft of a writing brush is a special-shaped staged light-wall pipe, enlarged diameter section is the bevel hollow cone, reduced diameter section is a hollow cylinder, the macropore of inner chamber is in a side of cone, the outer cylindrical surface thereof of hollow cylinder section is processed with screw thread, and aperture is a keyway near the end face vicinity; Outer proposition is not isometrical tubular, and enlarged diameter section is the bevel hollow cylinder, and there is spiral goove at the external cylindrical surface place, and axial groove is arranged on back, and groove has hole to communicate with inner chamber, and reduced diameter section is a hollow cylinder, and the inner chamber of proposition end is a macropore; Tube connector has screw thread for not isometrical hollow cylinder light-wall pipe, the macropore surface of enlarged diameter section, and screw thread is also arranged on the external cylindrical surface of reduced diameter section; The shape of guide spiro rod is not isometrical hollow cylinder, is processed with screw thread on the major diameter external cylindrical surface of stage casing, and the guiding keyway is arranged vertically, and the both sides section is the minor diameter hollow cylinder; Adjusting lever is special-shaped hollow thin-wall pipe, on the aperture face of cylinder of the short enlarged diameter section of a side length, screw thread is arranged, the opposite side of adjusting lever is that its end of blind hole has the spheroid handle, middle long one section hollow cylinder, one axially open is arranged, be convenient to by dress leaf spring and suction operation, for the purpose of clearer, below with the general structural configuration of the two sharp fountain pens of both thick and thin, relevant position and annexation between each other part are described as follows: pen nib outside being equipped with in the macropore that shaft of a writing brush awl is held down, near in the outer pen nib in the arc be outer proposition in the inner chamber of the following shaft of a writing brush, in the macropore of outer proposition tongue end interior pen nib and interior proposition, in the inner chamber pore of outer proposition siphon pipe is housed, in order to suction, the external cylindrical surface of outer proposition hollow cylinder section is connected with the endoporus of guide spiro rod one end, the other end external cylindrical surface of guide spiro rod links to each other with the openend of a capsule, the keyway at the axial keyway at guide spiro rod external cylindrical surface place and following shaft of a writing brush reduced diameter section endoporus place is interconnected by feather key, make outer proposition, interior proposition, between interior pen nib and outer pen nib, moving to axial, keep the radial direction unanimity when flexible, pen is assisted in the inner chamber that together is contained in adjusting lever under the clamping of leaf spring, the long example of leaf spring is placed on the opening part of adjusting lever, a so that compression leaf spring capsule suction, the threads engaged at the inner hole thread of adjusting lever one end and external cylindrical surface place, guide spiro rod stage casing, be limited in the macropore of tube connector by having the end face of externally threaded positioning retainer ring adjusting lever, make it when rotating, not produce axial motion, the large diameter inner hole thread of tube connector links to each other with screw thread on the following shaft of a writing brush reduced diameter section outer cylinder surface, the inner hole thread of the last shaft of a writing brush one side links to each other with external screw thread on the tube connector minor diameter, pen hanging is fixed on cap for brush end by snap-fastener, the cap for brush is enclosed within on the external cylindrical surface of tube connector and in last shaft of a writing brush end face and contacts, now the method for adjustment with the two sharp fountain pens of both thick and thin is described as follows: take the cap for brush, the knob of twisting adjusting lever, the other end rotates in tube connector under the qualification of positioning retainer ring, owing between the guide spiro rod and the following shaft of a writing brush feather key is arranged, the inner hole thread of adjusting lever drives guide spiro rod and moves axially, the outer proposition that is connected with guide spiro rod and on interior pen nib, interior proposition, siphon pipe, capsule also moves together, and maintenance radial direction unanimity, when interior pen nib stretch out use during pen nib outside being longer than in pen nib, the outer pen nib of use when being shorter than outer pen nib of shrinking back.

The utility model is improved to form on a kind of basis of existing fountain pen, improvement has increased pen nib, proposition, guide spiro rod, tube connector, feather key, adjusting lever, reverse adjusting lever, interior pen nib that guide spiro rod is connected with it etc. is moved together, stretch out and shrink back, relative position in the conversion between pen nib and outer pen nib, be implemented in the pen nib that uses two kinds of different thicknesses on the pen, this utility model is used one more, rational in infrastructure, easy to manufacture, use easy to carry.
