Abstract

PURPOSE: To obtain an automatic lead replacing paintbrush having writing leads of various hardnesses by pushing down a writing bar, driving a push bar to push out the lead, and projecting the lead by the writing lead for replacing the previous lead with next replacing lead. CONSTITUTION: At the time of pushing out a writing lead 51 to write a character, a push bar 14 is moved upward according to a writing bar 10, and separated from a lead output tube 30. Thus, the lead 51 is slidably dropped to introduce it into the tube 30, received by a braking of a tube wall of a fine tube 32, and the lead 51 is stopped in the tube 30. At the time of intending to replace the lead, the bar 10 is turned, a protrusion 18 is separated from a writing fixed groove 211, introduced into a limited guide groove 21, further the bar 10 is pushed upward, slipped in the tube 30 to be exposed next. Thereafter, the bar 1 is further pushed back downward, and the lead 51 is received by a thrust force of a writing lad 52 and then projected from the tube 30.

Description

DETAILED DESCRIPTION OF THE INVENTION This term refers in particular to a multi-row refill type automatic refill writing/painting brush.

[Conventional technology]

Pencils in general use today are roughly divided into three types.The first type is an early wood-based pencil, which is not only inconvenient but also requires constant sharpening with a knife or pencil splitter. It's unsafe. The second type is a mechanical pencil with a pre-made lead, in which the pre-made lead with multiple sections is placed in a heavy tube, and when the lead becomes thick or breaks, only that section is used. Replace the pencil lead to expose a new one.However, as you have to touch the lead with both hands during the removal/insertion process, it easily stains your hands.Therefore, there is no such type of hand refill available on the market. Released a mechanical pencil that does not require removing or inserting a brush lead, and has put it into practical use.
Offal has the advantages of hygiene and convenience. The third type is an automatic mechanical pencil with a fine lead.The lead is approximately 0.5M, so the lead remains sharp and thin from beginning to end when writing, so it can be used as a drafting pencil at all times.

Taking all of the above into account, all types of pencils have their own points, but their common drawback is that each pencil can only use a lead of a certain hardness, for example, H.
B, B2, B, etc. In addition, brush leads of various hardnesses all have their specific uses, such as B2, which is often used for drawing lines on computer cards, ■, which is often used for drawing edges in drafting, and HB, which is often used for drawing lines on computer cards. If you need to use pencil leads of various hardness, such as when copying books, you will need to prepare several different types of pencils or pencil leads, so it will be difficult to carry them when using them. Form an inconvenience.

Therefore, today we put it in a single heavy tube with a kind of pencil lead of various hardness,
In addition, a calligraphy and painting brush with a cold part that can quickly and accurately change the tip of the brush is required.

This invention provides an automatic refill-replaceable calligraphy and paintbrush with a refill.

A replacement paintbrush, including an inner brush, an outer heavy pipe, a centering pipe and a rotating brush, of which the bottom end of the inner brush extends downward. At the same time, a plurality of evenly distributed axial shell lead tubes are created on the circumference of the inner rod using the push rod, and an axial guide groove is created on the brush lead tube to allow each brush lead to pass through. A ring-shaped guide groove is provided at the bottom end of the inner brush rod, and a protrusion is provided on the tube wall of the pen tube below the guide groove, and a protrusion is provided on the tube wall of the pen tube below. I'm trying to stay calm.

The outside heavy tube is a hollow circular tube that allows the pen rod to be inserted into it, and has a positioning hole at the bottom end of the tube, and a limit guide groove at the top end. The protrusion at the top end of the inner writing rod is inserted into the opening to limit the vertical movement of the writing rod.

The rotating pen is a hollow circular tube, the bottom end of which is a shrinking tube wall,
Moreover, its top end is sleeved into the bottom end of the outer heavy tube, and a plurality of protruding points are provided on the wall of the rotating heavy tube, facing each other, so that it can be inserted into the positioning hole. . There is a V-shaped concave groove on the tube wall at the waist, the inward side of which forms an elastic hook and has an inwardly W-curved hook head, which passes through the axial guide groove into the pencil lead tube. It can be expanded into.

The centering tube is also a hollow circular tube that accepts push rods and pencil leads.
A convex flange is provided at the top end of the centering tube, and the centering tube is placed inside the turning pipe, and the convex flange is located at the top end of the inner wall of the contraction tube wall of the single turning heavy pipe, and the bottom end of the centering tube is slightly turned. Open two vertical grooves on the centering pipe exposed to the heavy pipe,
The centering tube has a slight elasticity, and the tube wall at the bottom end is appropriately reduced to provide a considerable braking force to the inner core between them, and - as soon as thrust is received, the centering tube wall will be slightly reduced. The centering tube expands, and some of the volume smoothly slides out of the centering tube, and at the same time, the bottom end of the centering tube receives pressure from the bottom outlet of the rotating heavy tube, making it easier to write with the tip. to clamp.

During operation, turn the rotating pen and insert the protruding points facing each other with the tip to be exposed into the positioning hole, and the hook head will extend into the tip tube of the tip to be exposed. Push the inner rod upward, and the hook head moves downward along the axial guide groove facing each other, causing the lead to protrude from the writing tube, as well as detaching from the centering tube with the push rod and slipping into the centering tube. , further push the inner stick downwards,
Use a push stick to push out a portion of the lead and rub it so that you can write on it. Limit guide bη A single ring-direction writing fixing groove is opened at the bottom end, and the inner writing rod is rotated to fit the protrusion into the writing fixing groove, so the movement of the inner writing rod is restricted and characters can be written. Do it like this.

When replacing the pencil lead, simply insert the protruding lead that is about to be exposed into the centering tube according to the above procedure, hit the top of the exposed pencil lead, and then push the inner rod downwards.

The push rod applies a thrust to the brush lead that is about to be exposed, causing the exposed brush lead to detach and projecting the partial volume of the brush lead that is about to be exposed, thus achieving the purpose of replacing the brush lead.

When re-inserting the refill, place the receptacle on the upper surface of the brush or use your finger to forcefully push it back into the recess, then pull up the inner rod until the height of the push rod reaches the top of the refill. At this time, the protrusion is located near the middle of the limit guide groove, so open one lead collection fixing groove along the axial direction, and turn the inner stick to remove the protrusion. Fits into the lead collection fixing groove to restrict the movement of the inner stick.
