Description

Pen cap

Technical Field

The utility model relates to articles for human life, in particular to stationery, and particularly relates to a pen cap.

Background

In daily life, the length and diameter of pen points of fountain pens or oil-based pens such as marker pens and white board pens are different. Therefore, when the cap is lost, it is often difficult to find the same cap, only exposing the tip to air, so that the tip dries out and damages quickly. Although the pen cap and the pen body can be connected through a rope such as a rubber band to reduce the loss of the pen cap, the writing experience is seriously influenced; moreover, not only the oil pen has thick and thin two ends, but also the thin head has small volume and higher loss probability, but often has no pen clip which can be connected with a rubber band, and is not suitable for being bound and fixed by the rubber band and the like. Alcohol-proof marker pens used for carrying out scientific experiments are expensive and often damaged due to careless loss of the pen cap by experimenters. The woodwork paint pen also belongs to an oil pen, and many pens do not have pen clips, and the pen holder and the pen cap of the round roller often roll off or even the pen cap is lost, so that the pen is damaged quickly. The pen points of various water pens or oil pens have different lengths and diameters, and the pen caps are difficult to match with each other.

Disclosure of Invention

The utility model aims to provide a pen cap, which aims to solve the technical problems that pen caps of various pens in the prior art are difficult to match with each other, are difficult to plug and pull and are easy to lose.

The utility model relates to a pen cap which comprises a cap body, wherein one end of the cap body is provided with an opening, the other end of the cap body is provided with a threading hole, a first cavity, a second cavity and a third cavity are arranged in the cap body, the first cavity, the second cavity and the third cavity are sequentially distributed from the opening end of the cap body along the axial direction of the cap body, an elastic sleeve is arranged in the second cavity, the inner side wall of the elastic sleeve is a conical surface, the diameter of one end, adjacent to the first cavity, of the elastic sleeve is larger than that of the other end of the elastic sleeve, the diameter of the first cavity is larger than that of the elastic sleeve, the inner diameter of the elastic sleeve is larger than that of the third cavity, at least two convex blocks are arranged on the outer wall of the opening end of the cap body along the circumferential direction, a plurality of friction stripes are arranged on the outer wall of the cap body at intervals along the circumferential direction, and the length direction of the friction stripes is parallel to the length direction of the cap body.

Furthermore, the elastic sleeve is composed of a silicone tube.

Furthermore, the other end of the cap body is connected with a pen clip.

Furthermore, the bumps are uniformly arranged along the circumferential direction.

Compared with the prior art, the utility model has positive and obvious effect. The elastic sleeve of the pen cap is in a conical funnel shape, the tip of the elastic sleeve is narrowed, and the tip of the pen point with different lengths and diameters close to one end of the pen point and the pen point can be inserted into the pen cap together with the pen point by increasing the diameters of the first cavity and the elastic sleeve of the pen cap, and the pen cap is clamped in the elastic sleeve to realize fixation. The pen point can be suspended in the third cavity, so that the pen point can be prevented from being exposed to air, the damage caused by rapid drying is prevented, and the pen point cannot be damaged or ink can be pumped out due to the fact that the pen point touches a hard object or a water absorption object. To the nib of special shapes such as triangle-shaped body of a brush and trapezoidal thickening nib, the dynamics that inserts and extract the cap for brush needs is bigger, consequently on the basis that sets up the friction stripe, evenly sets up at least a pair of lug along the circumferencial direction at cap for brush opening part lateral wall to conveniently increase frictional force, make the pen insert and extract more easily convenient. The threading hole is used for connecting a rope with the pen cap, so that the pen cap can be hung or fixed, and the phenomena of pen cap loss and the like are reduced. The pen clip is convenient to clamp the pen at the position of a diary, a white overcoat and the like, and meanwhile, the pen is prevented from rolling off when being horizontally placed, so that the pen is better protected.

Detailed Description

Example 1

As shown in figures 1 and 2 and 3, the pen cap comprises a cap body 1, wherein one end of the cap body 1 is provided with an opening, the other end of the cap body is provided with a threading hole 2, a first cavity, a second cavity and a third cavity are sequentially distributed from the opening end of the cap body along the axial direction of the cap body, the cap body 1 is internally provided with a first cavity 3, a second cavity 4 and a third cavity 5, the first cavity 3, the second cavity 4 and the third cavity 5 are sequentially distributed from the opening end of the cap body along the axial direction of the cap body, an elastic sleeve 6 is arranged in the second cavity 4, the inner side wall of the elastic sleeve 6 is a conical surface, the diameter of one end, adjacent to the first cavity 3, of the elastic sleeve 6 is larger than the diameter of the other end of the elastic sleeve, the diameter of the first cavity 3 is larger than the inner diameter of the elastic sleeve 6, the inner diameter of the elastic sleeve 6 is larger than the diameter of the third cavity 5, at least two convex blocks 7 are arranged on the outer wall of the opening end of the cap body 1 along the circumferential direction, a plurality of friction stripes 8 are arranged on the outer wall of the cap body 1 along the circumferential direction at intervals, the longitudinal direction of the friction stripe 8 is parallel to the longitudinal direction of the cap body 1.

Furthermore, the elastic sleeve 6 is composed of a silicone tube.

Further, the other end of the cap body 1 is connected with a pen clip 9.

Furthermore, the bumps 7 are uniformly arranged along the circumferential direction.

Specifically, the cap body 1, the elastic sleeve 6, the friction stripe 8, the pen clip 9, and the like in this embodiment all adopt the known solutions in the prior art, which are known to those skilled in the art and will not be described herein again.

The working principle of the embodiment is as follows:

the length and the diameter of the pen point of the fountain pen or the oil pen with different lengths and diameters have deviation from one end of the pen point tip close to the pen point and the length and the diameter of the pen point, but the numerical values are relatively uniform. The elastic sleeve 6 is set to be in a conical funnel shape, the tip narrows down, one end, close to the pen point, of the tip of the pen point with different lengths and diameters can be inserted into the pen cap together with the pen point by increasing the diameters of the first cavity 3 of the pen cap and the elastic sleeve 6, and the tip is clamped in the elastic sleeve 6 to be fixed. The pen point can be suspended in the third cavity 5, so that the pen point can be prevented from being exposed to air, the damage caused by rapid drying is prevented, and the pen point cannot be damaged or ink can be drained due to the fact that the pen point touches a hard object or a water absorption object.

To the nib of special shapes such as triangle-shaped body of a brush and trapezoidal thickening nib, the dynamics that inserts and extract the cap for a brush needs is bigger, consequently on the basis that sets up friction strip 8, sets up at least a pair of lug 7 at cap for a brush opening part lateral wall to conveniently increase frictional force, make the pen insert and extract more easily convenient. The threading hole 2 is used for connecting a rope with the pen cap, so that the pen cap can be hung or fixed, and the phenomena of pen cap loss and the like are reduced. The pen clip 9 is convenient for pinning the pen on the diary, white overcoat and other positions, and simultaneously reduces the rolling of the pen when horizontally placed, thereby better protecting the pen.
