Detailed Description

In order to make the technical problems solved, technical solutions adopted, and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention are described in further detail below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1 to 5, the present embodiment provides an anti-detachment structure for a writing pen, which improves the connection strength between the components of the writing pen, and prevents the components of the writing pen from loosening and falling off when the ambient temperature and humidity change.

The anti-drop structure of the writing pen comprises a first pen body 10 and a second pen body 20, wherein the first pen body 10 and the second pen body 20 are nested, and parts on the writing pen are in nested connection in an assembly state, so that the first pen body 10 and the second pen body 20 can be defined as any two connected parts of the writing pen.

The writing pen generally comprises an active writing pen and a passive writing pen, and the principles of the active writing pen and the passive writing pen are different;

enough touch area of the pen point of the passive writing pen can absorb enough electric signals to simulate fingers, and the electric signals are transmitted to the hand through the conductive pen holder.

The active capacitive stylus circuitry actively draws more current, requiring a power supply.

The precision of the two is different;

the nib of the active writing pen is thinner than that of the passive writing pen, so that the precision of the active writing pen is higher than that of the passive writing pen, but the active writing pen cannot be used at all under the condition that the electric quantity of the active writing pen is zero.

Because processing errors objectively exist among parts, an objectively existing assembly gap 50 is also formed between the first pen body 10 and the second pen body 20, and the assembly gap 50 can be a gap between an open cavity formed at one end of one pen body component and another pen body component or a sealed cavity formed by enclosing the inside of each writing pen in an assembly state. Thus, in the case that the fitting gap 50 is a sealed cavity, during the process of assembling the first pen body 10 and the second pen body 20, some air exists in the fitting gap 50, and the air cannot be smoothly discharged out of the fitting gap 50 when the air expands due to heat, so that the technical problems mentioned in the background art exist.

To solve this problem, a recess is provided at the first pen body 10 and/or the second pen body 20 to form a first air groove 21 between the first pen body 10 and the second pen body 20;

as described above, the first air tank 21 has three embodiments:

1) the first air groove 21 is arranged on the first pen body 10;

2) the first air groove 21 is arranged on the second pen body 20;

3) the first air groove 21 is disposed on the first pen body 10 and the second pen body 20, and the first air groove 21 disposed on the first pen body 10 and the second pen body 20 can be disposed relatively to form an air passage with a larger cross-sectional area by splicing, or disposed in a staggered manner.

As shown in fig. 4, the present embodiment adopts the mode 1) as an exemplary explanation.

In the using process of the writing pen, if the temperature of the writing pen rises due to the influence of the external environment or the body temperature of the user, the temperature of the air in the assembling gap 50 rises accordingly, in a relatively closed space, the air expands in the temperature rising process, so that the original air pressure equal to the atmospheric pressure is increased, that is, the air pressure in the assembling gap 50 is greater than the atmospheric pressure outside the writing pen, under the condition that the assembling gap 50 is not changed, the air is heated to expand, so that the pressure intensity between the first pen body 10 and the second pen body 20 is increased, but due to the existence of the first air groove 21, in the air expanding process, the expanded air can be discharged out of the assembling gap 50 through the first air groove 21, so that the air pressure in the assembling gap 50 is balanced with the atmospheric pressure outside the writing pen, and finally, the pressure exerted on the first pen body 10 and the second pen body 20 by the air in the assembling gap 50 is not changed, so that the condition that the first pen body 10 and the second pen body 20 are pressed towards the directions away from each other due to the expansion of the air is avoided, the nesting between the first pen body 10 and the second pen body 20 is ensured to be firm, and the structural stability of the writing pen is ensured.

Specifically, the connection between the first pen body 10 and the second pen body 20 is preferably in two ways:

one end of the first pen body 10 is provided with a mounting hole 11, and the second pen body 20 is provided with a mounting column 22;

one end of the first pen body 10 is provided with a mounting column 22, and the second pen body 20 is provided with a mounting hole 11.

Theoretically, the structure of the first air groove 21 is not particularly required, as long as both ends can communicate the assembly gap 50 with the external environment of the writing pen to achieve the effect of balancing the air pressure, the structure may be a winding structure or a zigzag structure, but in order to enable the air in the assembly gap 50 to be more smoothly discharged from the first air groove 21 after expanding, the first air groove 21 extends along the nesting direction of the mounting hole 11 and the mounting post 22, that is, the nesting direction of the mounting hole 11 and the mounting post 22, when the first air groove 21 is arranged on the mounting hole 11 and/or the mounting post, the first air groove 21 is a linear structure, and the extending direction thereof is parallel to the central axes of the mounting hole 11 and the mounting post, so as to avoid that the first air groove 21 with an excessively complicated structure affects the discharge of the air.

As described above, because the mounting hole 11 and the mounting post 22 are in interference fit, the assembly gap 50 between the first pen body 10 and the second pen body 20 is formed between the end of the mounting post 22 and the mounting hole 11, the extension length of the first air groove 21 is the same as the length of the mounting hole 11 and/or the mounting post 22, the first air groove 21 can communicate with the external environment of the writing pen at two ends of the mounting post 22 and the mounting gap, and the communication between the mounting gap and the external environment is ensured.

Because of the uncertainty of the machining error, when the air in the assembly gap 50 expands, the pressure applied to different positions of the end of the mounting post 22 may also be different, and it is preferable to provide a plurality of first air grooves 21 between the mounting holes 11 and/or the mounting posts, and the plurality of first air grooves 21 surround the inner hole wall of the mounting hole 11 and/or the outer cylindrical surface of the mounting post 22 at equal intervals, so that even if the air pressure at different positions of the end of the mounting post 22 is higher than that at other positions in the air expansion process, the air can be timely discharged from the first air grooves 21 at the corresponding positions, and the air discharge efficiency in the assembly gap 50 can be improved.

Furthermore, the inside of the mounting hole 11 is provided with a positioning rib plate 12 in a sealing manner, the positioning rib plate 12 is of a plate-shaped structure, so that the mounting hole 11 is plugged to form a blind hole, after the mounting column 22 is inserted into the mounting hole 11, the tail end of the mounting column 22 abuts against the positioning rib plate 12 to position the assembly position of the first pen body 10 and the second pen body 20, the second pen body 20 is positioned, the assembly gap 50 is formed between the positioning rib plate 12 and the end of the mounting column 22, the extension length of the first air groove 21 is consistent with that of the mounting column 22, that is, the two ends of the mounting column 22 can be communicated, so that the assembly gap 50 is communicated with the external environment.

The present embodiment further provides a passive writing pen for operating a touch screen, which includes the above-mentioned pen-out preventing structure and the third pen body 30, wherein the third pen body 30 and the first pen body 10 are nested, and the third pen body 30 and the second pen body 20 are respectively disposed at two ends of the first pen body 10.

For convenience of description, the present embodiment defines the first pen body 10 as a pen point, the second pen body 20 as a pen point, and the third pen body 30 as a pen holder, wherein one end of the pen point far from the pen point forms a writing part 23 for operating the touch screen, and a user can perform writing operation on the touch screen by holding the pen holder with the writing pen.

In this embodiment, the nib is formed by the sintering of PE material, and the nib that forms by the sintering of PE material can provide one kind and be close to real writing feedback for user's hand writing the in-process, improves user's writing experience and comfort.

Because the PE material is softer, in order to improve the structural strength of nib, the nib is embedded to have stereoplasm support refill 24, and softer PE material cladding is in support refill 24 to let support refill 24 provide the support for the PE material, also can promote certain PE material surface hardness, let it more be close to write the sense.

Mounting hole 11 is kept away from to the nib, and the one end that is not equipped with the nib is provided with fixed column 13 promptly, and fixed column 13 is fixed pegs graft in fixed orifices 32, and what need explain here is because the nib diameter is less than the nib, consequently, set up mounting post 22 at the nib, set up mounting hole 11 in nib one end, let the one end that the nib was located to the nib cover, avoid the nib to need set up the connection structure that the diameter is greater than the nib, improve nib and nib part compact structure, also let the structure of writing a more pleasing to the eye. Similarly, because the nib diameter is less than the pen-holder, consequently, set up fixed column 13 on the nib, set up fixed orifices 32 on the pen-holder, let the pen-holder cover locate the one end of pen-holder, avoid the nib to set up the connection structure that the diameter is greater than the pen-holder, improve pen-holder and nib part compact structure nature, also let the pen structure more pleasing to the eye. Similarly, the pen tail 40 and the pen holder are also provided with the same hole column connecting structure.

It should be noted here that the diameter of the writing part 23 in this embodiment is larger than that of the mounting post 22, so that a step structure is formed between the writing part 23 and the mounting post 22, and when the mounting post 22 is inserted into the mounting hole 11 of the pen head, the writing part 23 can abut against the pen head, but due to the existence of processing and assembling errors, a certain gap is also formed between the writing part 23 and the pen head, and two ends of the gap can communicate the first air groove 21 with the external environment of the writing pen, so as to achieve the air exhaust effect.

In order to improve the connection strength between the pen point, the pen tail 40 and the pen holder, the diameters of the two opposite ends of the installation cavity 31 are gradually reduced towards the middle of the installation cavity 31, so that the diameter of the middle of the installation cavity 31 is smaller than that of the two ends of the installation cavity, and thus, the fixing column 13 of the pen point and the column structure arranged on the pen tail 40 can be wedged tightly in the installation hole 11 and the hole structure when being inserted into the fixing hole 32 and the hole structure at the two ends of the pen holder, and larger friction force is generated between the pen point and the pen holder and between the pen tail 40 and the pen holder through a wedge effect.

In this embodiment, the pen point and the pen tail 40 are separately disposed at two ends of the pen holder, so that the mounting cavity 31 forms a relatively sealed cavity, and therefore, a concave portion is disposed on the fixing hole 32 and/or the fixing post 13 to form a second air groove (not shown) between the pen point and the pen holder, the second air groove communicates with the mounting cavity 31 and the external environment to balance the internal and external air pressures of the mounting cavity 31, thereby achieving the technical effect achieved by the first air groove 21, and similarly, the second air grooves are multiple and are disposed at equal intervals around the periphery of the fixing hole 32 and/or the fixing post 13.

The present embodiment further provides an interactive tablet, which includes a touch screen and the passive stylus as described above, where the passive stylus can perform a touch operation on the touch screen through the writing portion 23.
