Description

a writing pen

technical field

The utility model relates to a pen, in particular to a writing pen.

Background technique

Today's writing pens are generally ballpoint pens and water-based pens. They are popular because they are easy to use and take a long time to write. However, these pens are generally designed with a pen cap. Take out the pen cap when using it, and put the pen cap on when not in use. Closed on the body of the pen, people who have used it will find that the pen cover of this type of pen is easily lost, it is inconvenient to carry, and it is easy to leave stains on the pen.

Contents of the invention

Aiming at the deficiencies of the existing solutions, a writing pen is proposed for the utility model.

The utility model is achieved in this way. A writing pen includes a pen core mechanism and a pen body. The pen core mechanism is placed in the pen body. The pen core mechanism includes a button assembly, a pen core, and a spring tube. At the bottom of the button assembly, the spring tube is fixed and sleeved on the pen core, and the button assembly includes a fixed vertical rod and a diagonal rod;

The surface of the pen body is provided with a scale line, the pen body is provided with a pen clip, and the pen body is provided with a through hole and a pressing hole that are both obliquely upward, and the through hole and the pressing hole can be fitted with the end of the oblique rod Matching, the through hole is located above the pressing hole, and the pressing hole corresponds to the clamping point of the clip.

It can be seen that the writing pen is usually in two states, one is when in use, when the end of the oblique rod is fitted in the pressing hole, the pen core presses the spring tube and stretches out the pen body; The second is that when not in use, when the clamping point of the pen clip is pressed against the end of the oblique rod, the end of the oblique rod will retreat to the inside of the pen body, and the pen core will move upward and return through the rebound of the spring tube. In the pen body, at the same time, the end of the inclined rod is driven to move up and fit in the through hole, so that the button assembly will not be separated from the pen body.

Scale lines are arranged on the body of the pen, so that the writing pen has the function of a ruler.

As a further improvement of the above-mentioned solution, the button assembly further includes a button, which abuts against the top of the vertical rod and extends out of the upper port of the pen body.

As a further improvement of the above solution, a protruding ring is provided at the lower end of the pen core, and the spring is tightly clamped between the protruding ring and the lower port of the pen body, and the lower end of the pen body is gathered into a cone shape. The lower end of the pen body is the nib, and the pen core is stuck in the lower port.

As a further improvement of the above solution, the oblique rod is an elastic rod that can move relative to the vertical rod.

As a further improvement of the above solution, the cross-section of the upper end of the pen body is a regular octagon. In this way, the writing pen will not roll, and the body of the pen is convenient to be used as a ruler, and the grip is more comfortable.

As a further improvement of the above solution, the button forms a seamless movable cooperation with the pen body.

As a further improvement of the above solution, the button, the vertical bar and the oblique bar are integrally formed, which is simple in structure and easy to use, and will not cause loss of fragments after disassembly, and avoid the trouble of being unusable.

As a further improvement of the above solution, the pen core is a ball core.

As a further improvement of the above solution, the clip is in the shape of a long ear, and the clamping point is located inside the lower end of the clip. Can be clipped to a book or collar.

The utility model has the advantages that the pen core can be retracted automatically, and the pen cap is not needed, the utility model can be used as a ruler, and the structure is simple.

Detailed ways

In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only for explaining the present invention, and are not intended to limit the present invention.

Referring to Fig. 1, Fig. 2 and Fig. 3, a writing pen includes a refill mechanism 1, a pen head 2, a pen body 3, and a pen holder 4.

The pen body 3 is a shell-shaped octagonal columnar structure, the refill mechanism 1 is placed in the pen body 3, and forms a closed structure with the pen body 3, and the pen clip 4 is in the shape of a long ear, and is perpendicular to the upper end of the pen body 3 One surface, and the upper and lower ends of the pen clip 4 are respectively provided with clamping points, the clamping point at the upper end is fixedly connected with the pen body 3, and the clamping point at the lower end fits the pen body 3;

The pen body 3 is provided with a through hole 31 and a pressing hole 32 arranged up and down, and the clamping point at the lower end of the pen clip 3 corresponds to the pressing hole 32; the through hole 31 and the pressing hole 32 are both inclined upward.

One surface of the pen body 3 can be used as a ruler for marking lines, and the two adjacent surfaces of the surface are respectively provided with length scale marks, and the surface is opposite to the surface where the pen holder 4 is located. In this way, the writing pen has the function of a ruler, and can conveniently draw a straight line of a desired length without a ruler.

The nib 2 is a cone-shaped shell, located at the lower end of the pen body 3, and connected through the pen body 3;

The refill mechanism 1 includes a button 11, a button post 12, a holding plate 13, a vertical bar 14, an oblique bar 15, a disk 16, a refill 17, a raised ring 18, and a spring tube 19 arranged in sequence from bottom to bottom; Button 11, button column 12, top holding plate 13, vertical bar 14, oblique bar 15, disc 16 constitute button assembly, and this button assembly is integrally formed structure.

The button 11 is a cylinder, a part of which is located outside the upper end of the pen body 3 , and another part is located inside the pen body 3 , and the button 11 and the pen body 3 form a seamless movable fit. The upper end of the vertical rod 14 is connected with the top holding plate 13, the lower end of the vertical rod 14 is connected with the disc 16, and the bottom of the oblique rod 15 is also connected with the disc 16, and the oblique rod 15 is movable relative to the vertical rod 14; The end of 15 is inclined, and can fit with the inclined through hole 31 and the pressing hole 32 . the

The pen core 17 is held against the bottom of the disc 16, the spring tube 18 is sleeved on the pen core 17, and the raised ring 18 is located at the lower end of the pen core 17, which is used to hold the spring tube 19 against the raised ring 18 and the nib 2 between.

It can be seen that the writing pen is usually in two states, one is when in use, when the end of the oblique rod 15 fits in the pressing hole 32, the pen core 17 is positioned below and stretches out the pen body 3, and at the same time , the pen core 17 presses the spring tube 19; the other is when not in use, when the clamping point of the pen clip 4 is pressed against the end of the oblique rod 15, the end of the oblique rod 15 returns to the inside of the pen body 3, and passes through The rebound of the spring tube 19 moves the pen core 17 upwards and returns to the pen body 3. At the same time, the pen core 17 drives the inclined rod 15 to move upwards, so that the end of the inclined rod 15 fits with the through hole 31; When the writing pen is not in use, because the end of the inclined rod 15 fits in the through hole 31, the button assembly will not be separated from the pen body 3.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
