Description

A kind of writing brush

Technical field

The utility model belongs to school supply and stationery technical field, and in particular to a kind of writing brush.

Background technique

Writing brush is a kind of traditional writing implement.Existing writing brush is made of penholder and nib, penholder and the direct phase of nib Even, production follows traditional handicraft, and penholder is made with bamboo or other materials, is made nib with animal wool, simple process but is fabricated to This height；Prepared Chinese ink and inkstone need to individually be prepared when use, need constantly to dip prepared Chinese ink in writing process, program is cumbersome and right when writing For beginner, when dipping prepared Chinese ink, since to will lead to writing effect bad for the not easy to control amount of dipping.

Utility model content

The purpose of this utility model is to provide a kind of writing brushes, and ink need to constantly be dipped in use by solving existing writing brush The problem of juice and the prepared Chinese ink amount of dipping not easy to control.

The technical scheme adopted by the utility model is a kind of writing brush, including the penholder being made of upper penholder and lower pen rod Main body, one end of the lower pen rod are detachably attached to writing brush head, and the lower pen rod inner hollow forms black pipe, described Writing brush head inner hollow forms ink channels after being connected with the ink pipe and extends to pen hair head, and the lower pen rod is far from the hair The other end of nib is fixed with connector, and the lower pen rod is movably connected by connector and upper penholder, inside the upper penholder Hollow, the connector is axially provided with through-hole along penholder, is provided with piston in the ink pipe, the piston and lower pen rod it is interior Wall fits, and the piston is connected with piston rod, and the piston rod passes through the through-hole.

Preferably, be provided with internal screw thread in the through-hole, the piston rod outer surface be provided with in the through-hole in The adaptable external screw thread of screw thread.

Further, external screw thread is set outside the connector, the upper penholder close to one end of lower pen rod be provided with The internal screw thread that external screw thread outside the connector is adapted.

Further, the lower pen rod is threadedly connect with writing brush head.

Preferably, the ink manages the lower ink pipe open at one end for being also connected with diameter and being less than black pipe diameter close to writing brush head, The lower black pipe extends to the pen hair head.

The beneficial effects of the utility model are: a kind of writing brush of the utility model will be set as hollow formation ink inside penholder Pipe recycles piston motion to extract prepared Chinese ink, then slowly, constantly provides prepared Chinese ink to writing brush head by ink channels, solves Existing writing brush need to constantly dip the problem of prepared Chinese ink and prepared Chinese ink amount of dipping not easy to control in use.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

A kind of writing brush provided by the utility model, structure is as Figure 1-Figure 4, including is made of upper penholder and lower pen rod Penholder body 1, one end of lower pen rod is detachably attached to writing brush head 4, and lower pen rod inner hollow forms storage prepared Chinese ink Ink pipe, formation and extends to pen hair head at ink channels after 4 inner hollow of writing brush head is connected with ink pipe, provides for pen hair Prepared Chinese ink, lower pen rod are fixed with connector 2 far from the other end of writing brush head 4, and lower pen rod passes through connector 2 and upper penholder activity phase Even, upper penholder inner hollow provides the space for accommodating piston rod, and connector 2 is axially provided with through-hole, setting in ink pipe along penholder 1 There is piston 3, piston 3 and the inner wall of lower pen rod fit, and piston 3 is connected with piston rod, and piston rod passes through through-hole.

In order to avoid piston moves down under the factors such as gravity, so that amount out of ink is excessive.Preferably, in connector 2 Internal screw thread is set in through-hole, and piston rod outer surface is provided with the external screw thread adaptable with the internal screw thread in through-hole.In use, passing through Rotary-piston bar realizes the slow movement of piston 3.

In order to facilitate prepared Chinese ink is drawn, then need easily to remove penholder.Therefore external screw thread is set outside connector 2, The upper penholder internal screw thread adaptable with the external screw thread outside connector 2 close to the setting of one end of lower pen rod, so that connector 2 It is connected through a screw thread with upper penholder, conveniently takes down penholder.

In order to facilitate prepared Chinese ink is drawn, lower pen rod is threadedly connect with writing brush head 4, after screwing off writing brush head 4 Draw prepared Chinese ink.

In order to avoid excessive to writing brush following ink, therefore manage in ink that be also connected with diameter small close to writing brush head open at one end In the lower ink pipe of black pipe diameter, it is that pen hair slowly provides prepared Chinese ink that lower black pipe, which is extended to pen hair head,.

Separated in use, Mo Guanyu writing brush head 4 is rotated, then spin off penholder, lifted upwards using piston rod piston 3 to Upper movement rotates lower pen rod so that form negative pressure in ink pipe draws prepared Chinese ink from ink bottle with writing brush head 4 and upper penholder respectively It tightens, prepared Chinese ink constantly slowly can provide a certain amount of prepared Chinese ink for the pen hair of writing brush head 4 at this time, and such ink supply mode is significantly less than white silk Habit person dips the frequency of prepared Chinese ink.
