Description

writing pen

technical field

The utility model relates to a stationery, in particular to a writing pen with simple structure and low manufacturing cost.

Background technique

Most of the writing pens currently on the market are composed of a pen holder, a nib, a pen cap, a pen core, and a connector. The connecting piece is connected with the pen holder to fix the tail of the pen core, which is convenient for the user to hold the pen holder for writing; the structure of this type of writing pen is complicated, and the cost of manufacturing the writing pen is high.

A kind of utility model patent whose authorization notification number is CN 201128313Y in China discloses a ballpoint pen; as a kind of writing pen, the ballpoint pen described in the patent is constructed by connecting a penholder, a nib and a refill; the lower end of the penholder of the ballpoint pen is provided with an inner Thread, the corresponding nib is provided with an external thread to connect with the pen barrel; the other end of the pen barrel is combined with the connecting piece to fix the tail of the pen core; when changing the pen core, it is necessary to separate the connecting piece from the pen barrel, and take out the pen from the rear end of the pen barrel core; or the nib is separated from the penholder, and the pen core is taken out from the front end of the penholder; the complex structure of this ballpoint pen increases the cost of manufacture.

Contents of the invention

In order to overcome the problem of complex structure existing in the existing writing pen technology, the purpose of this utility model is to provide a writing pen with simple structure and low manufacturing cost.

In order to solve the problem of complex structure and achieve the expected technical goal, the utility model provides a writing pen, including a pen holder, a pen holder, and a refill; the pen holder of the writing pen is composed of a ring-shaped tail end and two semicircular sections The pen body is formed as a whole; the ring-shaped tail end has an opening, and the openings on both sides extend outward to the ring-shaped tail end to connect with the two pen bodies respectively; A circular groove; the grooves are overlapped to form a cylindrical cavity, and the pen core is placed in the cylindrical cavity; the pen holder is sleeved around the outside of the pen body; the pen body and the ring The tail end as a whole simplifies the structure of the writing pen and reduces the manufacturing cost; at the same time, the groove is set as a semicircle because most of the refills on the market are cylindrical, and the semicircle groove can be easily installed Refill.

As a further optimization solution, the pen holder is made of elastic material; the elastic material provides the compression force needed to clamp the pen core near the ring-shaped tail end.

As a further optimization solution, the pen holder is made of bamboo; as a material with elasticity, bamboo provides the required compression force for the pen body, and the cost of using bamboo is low and environmentally friendly.

As a further optimization scheme, the groove is closed on the side close to the ring-shaped tail end of the pen holder; the side of the groove away from the ring-shaped tail end is provided with an opening for placing the writing end of the pen core, so as to expose the writing end to the The purpose outside the pen body is to facilitate the user to write; the other end is closed, which acts as a limit support for the core of the pen core.

As a further optimization scheme, the depth of the groove is less than the radius of the pen core; in order to fix the pen core, the depth of the groove is set to be less than the radius of the pen core, so that when the two pen bodies clamp the pen core When the core body cannot be completely closed, the pen barrel continues to provide compression force to fix the position of the pen core in the pen body.

As a further optimization solution, the pen holder that fixes the positions of the two grooves is made of rubber; the rubber is elastic and is easy to fix on the outside of the pen body; at the same time, it provides the compression needed to clamp the pen core away from the ring-shaped tail end Force, together with the compression force provided by the pen barrel, ensures that the position of the pen core does not shift; the rubber material can also facilitate the user to hold the pen body and help the writer to write smoothly.

As a further optimization solution, the pen holder is arranged on the outer side of the pen holder away from the circular tail end and close to the opening of the semicircular groove; this placement method conforms to the way most users hold pens, and is convenient for users write.

Due to the adoption of the above technical scheme, the writing pen provided by the utility model has such beneficial effects, that is, the whole writing pen has a simple structure, a small number of parts, practical materials are environmentally friendly, and the manufacturing cost is low; A placement method for hanging the pen body is provided.

Fig. 2 is a sectional view at A-A place in Fig. 1;

In the figure: pen barrel 1, pen body 11, circular end 12, semicircular groove 13, pen holder 2, refill 3

specific implementation plan

As shown in Figure 1, the pen holder 1 is an integral body composed of a semicircular pen body 11 and an annular tail end 12; As shown in Figure 2, the inner joints of the two pen bodies 11 are respectively provided with a groove 13 with a semicircular cross section; the semicircular groove 13 is closed to form a cylinder cavity; the pen core 3 is placed on the cylinder In the cavity, the pen holder 2 and the pen holder 1 jointly provide compression force to fix it.

The core of the pen core 3 is installed in the semicircular groove 13 on one side along the direction parallel to the pen body 11; the pen core 3 is placed in the semicircular groove 13, and the pen body 11 on the other side The elastic ring-shaped tail end 12 made of bamboo and the compression force provided by the pen holder 2 clamp the pen core 3 to achieve the purpose of fixing the pen core 3 in the pen body 11 .

The two pen bodies 11 are closed, so that the two semicircular grooves 13 on the inside are closed to form a cylindrical cavity; the writing end of the pen core 3 is placed at the opening of the cylindrical cavity; The cavity is closed on the side close to the ring-shaped tail end 12 to provide a supporting force for the pen core 3 parallel to the direction of the pen body 11 and to reinforce the position of the pen core 3 in the pen body 11 .

The pen holder 2 is sleeved on the outside of the pen body 11 along the parallel direction of the pen body 11 toward the side of the ring-shaped tail end 12 to further strengthen the pen core 3; meanwhile, the pen holder 2 is placed on the opening side close to the semicircular groove 13, To facilitate the user to write with the pen body 11 when writing.

When the ink in the pen core 3 is exhausted, the pen holder 2 is taken out toward the opening side of the semicircular groove 13 along the parallel direction of the pen body 11, and the pen core 3 is taken out and replaced; the ring tail end 12 of the writing pen is for use The latter provides a method for hanging and placing the writing pen; the user can hang the writing pen by passing the hanging end of the hook through the inner ring of the annular tail end 12.
