Description

A kind of writing pencil of dropping of preventing

Technical field

The utility model relates to a kind of writing pencil, the writing pencil in particularly a kind of writing pencil groove that places electronic equipment such as mobile phone.

Background technology

Along with development, the progress of science and technology of society, mobile phone, electronic equipments such as PDA have become the important communication of people, Work tool.It is frequent day by day that these electronic equipments of simultaneous use, and people are also increasingly high to its requirement, thereby the mobile phone of band touch-screen, PDA etc. have occurred.Wherein, the mobile phone of touch-screen, PDA all adopt writing pencil to click screen usually, and writing pencil is light, exquisite, have solved problems such as spelling trouble.

The writing pencil that uses at present is usually designed to intercalation in the slot of electronic equipment one side, when the user need use writing pencil, takes out writing pencil in the slot and can use.

With reference to Fig. 1, it is the structural representation of the writing pencil of convention.Writing pencil is by nib 101, and 103 two major parts of penholder are formed.

But normally used writing pencil only depends on the friction part of penholder 103 upper ends that writing pencil 100 is fixed in the slot when inserting the mobile phone slot.If writing pencil uses frequent or through using for a long time, the friction part branch of penholder 103 upper ends of writing pencil becomes level and smooth gradually.Like this, writing pencil can occur becoming flexible when inserting the writing pencil groove, and writing pencil is as easy as rolling off a log to drop.In a single day the user has lost writing pencil, need look for him to replace by thing in addition, uses very inconvenience.And a general mobile phone only is furnished with a writing pencil, and the loss of writing pencil not only influences the attractive in appearance of mobile phone, and unpaired writing pencil possibly produce damage to mobile phone screen, the serviceable life of reduction mobile phone.

The utility model content

In order to address the above problem, the utility model provides a kind of writing pencil of dropping of preventing, it comprises:

Penholder, nib also comprises a locating device; Said nib and said locating device are separately positioned on the two ends of penholder; This locating device has elasticity, and in the time of in writing pencil is placed into the writing pencil groove, this locating device is compressed; Make the two ends and the writing pencil groove of writing pencil fit tightly, and can not drop.

Said locating device is the right cylinder of a diameter greater than penholder; Be provided with a groove in the said right cylinder; Said groove is divided into two semicylinders with said right cylinder, and said locating device comprises a U-shaped spring, and the two ends of said U-shaped spring place respectively in two semicylinders.

Preferably, said locating device is a plastic cylinder, and said periphery is a frosting.

A kind of writing pencil that drops that prevents that the utility model provided has following advantage:

The first, an end of writing pencil, drops from the writing pencil groove even therefore service time, length can not become flexible yet because of being provided with spring, has solved the problem that writing pencil drops.

The second, as long as two semicylinders that touch on the locating device during use just can take out writing pencil, use simple, convenient.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.

The utility model is through being provided with locating device, to reach the purpose that prevents that writing pencil from dropping on writing pencil.

See also Fig. 2, the utility model provided a kind of writing pencil of dropping of preventing comprises: nib 201, penholder 203 and locating device 205, wherein, said written 201 and said locating device 205 be separately positioned on the two ends of penholder 203.

In the embodiment one of the utility model, said locating device 205 is the right cylinder 205A of a diameter greater than penholder 203 diameters.As shown in Figure 3, said right cylinder 205A is provided with a groove 301, and said groove 301 is divided into left semicircle cylinder 305 and right semi-circle cylinder 307 with said right cylinder.

Said right cylinder 205A also comprises a U-shaped spring 303, and the both sides of spring 303 are separately positioned on left semicircle cylinder interior 305 and right semi-circle cylinder interior 307.

Further, said right cylinder 205A is the right cylinder that plastics are processed, and it has certain flexibility and elasticity.And, frosting is processed on the surface of said right cylinder 205A, can further increase the friction force between writing pencil and the writing pencil groove, prevent that to a greater degree writing pencil from dropping.

When using writing pencil,, has certain flexibility, therefore because of said right cylinder 205A is that plastics are processed; When the external world does not have resistance, 303 one-tenth free extended configurations of spring, its U-shaped expands into maximization; When writing pencil inserts the writing pencil groove, run into the pressure of writing pencil groove inwall, spring 303 is compressed; Make the two ends of writing pencil and the inwall of writing pencil groove fit tightly, again because the outside frosting of the right cylinder 205A of writing pencil makes that writing pencil is not easy from the writing pencil groove, to come off.

Because employing spring, its elasticity rate rely on the friction force location more lasting,, writing pencil repeatedly can not come off easily even using yet.And it is also fairly simple to take off writing pencil, only need touch left and right sides semicylinder 305,307, and writing pencil just can be taken out easily.

In the embodiment two of the utility model, as shown in Figure 4, said locating device 205 is that an xsect is the hemisphere 205B of U-shaped, and this hemisphere 205B is processed by resilient material.

When writing pencil is placed into the writing pencil groove, at first the sphere top of said hemisphere 205B is propped up the inwall of writing pencil groove one end, hemisphere 205B is compressed; Make the length of writing pencil shorten, thereby can easily put in the writing pencil groove, unclamp hemisphere 205B then; Its elastic force discharges a part; But not whole releases, make the two ends of writing pencil and the inwall of writing pencil groove fit tightly, and be difficult for from the writing pencil groove, coming off.

Further, the surface of said hemisphere 205B is a frosting, has further increased the friction force between writing pencil and the writing pencil groove.

In the embodiment three of the utility model, as shown in Figure 5, said locating device 205 is that an xsect is the hemisphere 205C of U-shaped, and being embedded with an xsect among this hemisphere 205C is the spring 501 of U-shaped.Compare with embodiment two, in embodiment three, control the elastic force of hemisphere 205C with spring; Elasticity than simple dependence material itself is more lasting; Elastic force is also bigger, thereby makes writing pencil to be placed on more securely in the writing pencil groove, and difficult drop-off.

Same, the surface of said hemisphere 205C is a frosting, with the friction force between further increase writing pencil and the writing pencil groove.

Above instance only is used to explain the structure and the principle of work of the utility model, can not be used for limiting the utility model.

More than the disclosed several specific embodiments that are merely the utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the utility model.
