Description

Push-to-pin core-out pencil case

technical field

The utility model belongs to stationery auxiliary products, more specifically, it is a pen cover used in conjunction with pen stationery such as crayons and chalks, and the pen can be pushed out by pressing and pinching. The pen cover can assist the pen to use better.

Background technique

At present, the mechanical pencils used in the domestic and foreign markets use a technology similar to pressing the core. Different mechanical pencils have different core-out methods, which can be divided into 4 types, namely, the core-dropping type, the rotating type, the pulsating type (push type) and the automatic compensation type (automatic core-out). Among them, the pulsating type (push type) is the basic structural form generally adopted by mechanical pencils, and the lead core is transported by pressing. The structure has a push type, that is, the lead core is pushed out once. The second push type, the first time the nib is pushed out of the pen holder, and the second time the lead is pushed out. Double chuck push type, adopting double chuck structure, which shortens the distance between the chuck and the end of the nib, so that the last 8-15mm residual lead in the mechanical pencil can produce a whole lead without pressing The core pushes it out, and you can write continuously.

The pulsating type (pressing type) is mainly composed of a pen holder, a tip cover (pen tip), a fixed core protection tube (movable damping), a chuck (blooming), a locking hoop, and a spring. When the storage core tube is affected by the pressing pressure (finger pressure), it overcomes the elastic force of the spring and moves downward, and the jaws of the chuck are opened. At the same time, the lead core leaves its original position in the storage core tube by its own gravity. Under the control of the damping ring of the brake element, it moves a certain length along the wall of the protective core tube. After the actuating pressure is released, the spring returns to its original position, and the lead core is automatically locked and positioned by the locking hoop and chuck, completing a pulsating core-out process. Reciprocating in this way can continuously pulse out the core.

The structure of the mechanical pencil solves the problem that wooden pencils often need to be sharpened, but it also has certain defects. It can only achieve the effect of writing similar to a pencil, and the fixed thickness of the lead core makes it impossible for people to adjust to the thickness they want when using it like a wooden pencil. In addition, the mechanical pencil, as its name suggests, is essentially a pencil stationery and is not used in other pen stationery. Its slender shape makes it inconvenient for children to handle, and they cannot arouse interest in writing and drawing.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, to provide a reasonable structure, easy to use push and pinch type core-out pencil case.

The purpose of this utility model is achieved through the following technical solutions. The structure of the press and pinch type core-out pen case includes the pen case shell, sponge, movable damping tube, core guard tube with chuck, locking hoop, spring, and movable ball. The locking hoop is installed on the card with the core guard tube On the outside of the head, the spring is installed under the middle protruding part of the core tube with the clip; a sponge of a certain shape is placed in the shell of the pen cover, and the movable damping tube is installed inside the sponge; the locking hoop and the spring belt are installed The card head protector tube is installed inside the movable damping tube; the movable ball is stuck in the tail of the pen cover shell and the depression of the card head protector tube.

As a preference: the chuck on the core-protecting tube with chuck is divided into three lobes, with a raised part in the middle and a circular depression in the tail. The locking band and the spring are not fixed on the core protector tube with the clamp head, but are installed on the outside and are in an active state.

As a preference: there is a circle of rectangular parallelepipeds arranged in a circle below the inside of the shell of the pen cover to prevent the movement of the clamping head. The shell of the pen case is made of silicone material, which is soft and healthy.

As a preference: the inwardly protruding part of the movable damping tube is used to hinder the movement of the locking band and the spring. The movable damping tube and the pen cover shell are fixed by glue, and the sponge is sandwiched between them.

As a preference: the movable ball is made of silica gel, and the inside is hollow, and the purpose of core removal can be achieved by pressing and pinching the movable ball. The movable ball is not fixed with glue, but is directly stuck between the tail of the pen case shell and the depression of the core-protecting tube with the clamping head.

The beneficial effect of the utility model is: the use method of the pen combined with the pen cover not only maintains the original state of the pen, but also allows the user to feel the comfort of writing. The way of pressing and pinching the movable ball out of the core increases the sense of fun. The silicone pen cover brings a soft and friendly feeling, and the built-in sponge is convenient for people to adjust to the best position for holding the pen for writing. For a paintbrush such as a crayon, putting on a pen cap can keep the user's hands, paper, etc. clean and tidy to a certain extent. At the same time, the cute shape of the pen cover arouses the interest of the user.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. Although the utility model will be described in conjunction with preferred embodiments, it should be understood that it does not mean that the utility model is limited to the embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

As shown in Fig. 1 and Fig. 2, the structure of the press-and-pinch pen case of this embodiment includes a locking hoop 1, a spring 2, a movable ball 3, a core-protecting tube with chuck 4, a movable damping tube 5, a sponge 6, and a pen case shell 7. The locking hoop 1 and the spring 2 are directly sleeved on the outside of the core-protecting tube 4 with a chuck, and do not need to be fixed, and are in an active state, as shown in FIG. 5 . On this basis, a movable damping tube 5 is installed on the outer side of the core guard tube 4 with a clip.

Described pen cover shell 7 first installs sponge 6 on the inner surface, then installs movable damping tube 5 toward sponge 6 inner surface, movable damping tube 5 and pen cover shell 7 are fixed with glue, and sponge 6 is clamped between the two automatically.

The movable ball 3 is installed in the circular depression 9 at the end of the core protector tube 4 with a clamping head, and is in contact with the pen cover shell 7, and is naturally sandwiched between the two, as shown in FIGS. 6 to 7 .

Before use, first insert pen stationery such as crayons and chalks into the pen case through the core outlet, and then it can be used normally, as shown in Figure 8. When encountering that the nib gradually becomes shorter, the purpose of drawing the nib can be achieved by pressing down with fingers or pinching the movable ball 3 left and right. This purpose is accomplished by the interaction of locking hoop 1, spring 2, movable ball 3, core guard tube 4 with chuck, and movable damping tube 5, and the deformation of movable ball 3 pushes core guard tube 4 with chuck to move downward. , but under the hindrance of the small cuboids arranged in the pen cover shell 7 and the movable damping tube 5, the spring 2 is compressed, and the locking hoop 1 moves, causing the three-lobed chuck 8 to open and push out the nib, as shown in Figure 5; When the ball 3 returns to its original shape, everything returns to its original position, but the tip of the pen has been pushed out. In addition, the soft pen cover can be deformed to a certain extent according to the force of the user's pinching, which satisfies the comfort.

The utility model can be used for pen holders that are difficult to use and are similar to crayons, chalks, etc., to assist them in writing and drawing better, as shown in Figure 8.
