Description

Pen with rotary pen cap

Technical field

The utility model belongs to study article field more particularly to a kind of pen with rotary pen cap.

Background technology

Pen is that a kind of essential writing implement, people are required for using in many occasions in people's daily life.It is existing Pen cap is lost in order to prevent on the market, some pens that pen cap and penholder link into an integrated entity, such as Publication No. CN occurs One kind disclosed in 106585189 A is entitled the pen of cap " setting flexible ", and when writing will can soon expose nib after pen cap, still There are a shortcomings to be for the patent：Because the reach on penholder and pen cap is different, if the screw thread on penholder is longer, Then the screw thread on penholder can expose comfortable when beautiful and use is influenced outside pen cap, if the screw thread on pen cap is longer, then in book There is larger gap between position not matched with screw thread on penholder and penholder on pen cap when writing, it may occur that larger trembles It is dynamic, and because pen cap in writing positioned at the holding position of user, shake occurs so that user's makes when writing It is excessively poor with experiencing.

Invention content

In view of the deficiencies of the prior art, the utility model proposes a kind of pen with rotary pen cap, by screw thread by pen cap It is connected as a single entity, pen tip need to be exposed, after use, pen tip is revolved upwards with after in use, pen cap is rotated down with penholder Turn, pen tip is wrapped up, such pen cap will not be lost, at the same be arranged on the bulge loop between pen cap and penholder can pen cap rotate and The stability between pen cap and penholder is kept when writing, meets ergonomics, penholder is made not shaken in writing.

To achieve the above object, the technical solution adopted is that：A kind of pen with rotary pen cap, includes penholder, pen Cap, the penholder lower end are provided with the nib hole being pierced by for pen tip, and the pen cap, which is spirally connected, is set in penholder lower end, and the pen Cap after rotation forms pen tip and covers or expose pen tip, and the screw thread that the reach on the penholder is less than on pen cap is long Degree is additionally provided with the bulge loop for keeping stability between pen cap and penholder, and bulge loop slip is set between the pen cap and penholder It puts between the screw thread in nib hole and penholder.

It in above structure, is connected through a screw thread between penholder and pen cap, pen cap can be rotating on penholder and move up and down. When needing to use, pen cap is rotated down, pen tip is exposed, after use, pen tip is rotated up, by pen tip packet It wraps up in, the advantages of this arrangement are as follows pen cap will not be lost, and simple in structure, it is easy to use.Because in writing, this practicality is new The pen cap of type is located at the handgrip part of user, in writing, pen cap is rotated down until pen tip is completely exposed, in gravity Under effect, bulge loop slides into pen cap front end, under the double action of bulge loop and screw thread so that phase is kept between pen cap and penholder To stabilization, prevent penholder from being shaken in writing.Simultaneously as the dual gravity of bulge loop and pen cap so that the center of pen is kept At the first half position of pen, the design of pen is made more to meet ergonomics so that user is more comfortable in writing.Nib hole and There are the spacing that one end supplies bulge loop slip between screw thread on penholder, and bulge loop height is less than the height of screw thread so that bulge loop is not The cooperation of screw thread on penholder and pen cap can be hindered, the screw thread on penholder and pen cap is allow steadily to be combined together.

Further, the pen cap is provided at both ends with the locating part for preventing pen cap from deviating from from penholder, the locating part mistake Cooperation be full of on the inside of the pen cap both ends, and the locating part internal diameter is less than bulge loop outer diameter.

In above structure, locating part cooperatively forms the limiting up and down to pen cap with two bulge loops respectively so that pen cap is revolving It will not deviate from from the screw thread of penholder when turning, further increase the stability in the utility model structure.

Further, the penholder rear end is detachably provided with that pen core is made to keep stable stability column, institute in writing It states stability column rear end and is wholely set the tail cap for preventing pen from rolling everywhere after the drops, far from tail cap on the stability column One end is provided with magnet.

In above structure, the purpose of dismountable stability column is set to be pen core is made to keep stablizing in writing, while Ink in pen core can easily replace its pen core after being finished.The shape of tail cap is quadrangle, and pen is being fallen It to after ground, will not be rolled everywhere under the action of tail cap, prevent pen from being rolled into after landing under desk and the feelings such as be difficult to take out The generation of condition.When without using pen, pen can be adsorbed on nigh irony object, such as the irony side in office table side Irony hook on irony part, wall on edge, desk etc., prevents because leaving about and there is a situation where can not find pen.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is specifically described.

By attached drawing it is found that the present embodiment is a kind of pen with rotary pen cap, include penholder 1, pen cap 2,1 lower end of penholder Portion is provided with the nib hole 11 being pierced by for pen tip, and pen cap 2, which is spirally connected, is set in 1 lower end of penholder, and pen cap 2 is after rotation to pen tip structure Into covering or exposing pen tip, the reach on penholder 1 is less than the reach on pen cap 2, between pen cap 2 and penholder 1 also The bulge loop 3 for keeping stability between pen cap 2 and penholder 1 is provided with, and bulge loop 3 is slidably arranged in nib hole 11 and penholder 1 Between screw thread.Pen cap 2 is provided at both ends with the locating part 4 for preventing pen cap 2 from deviating from from penholder 1, and locating part 4 is interference fitted in pen cap On the inside of 2 both ends, and 4 internal diameter of locating part is less than 3 outer diameter of bulge loop.Preferably, the screw thread on the present embodiment penholder 1 is arranged on and works as pen When 2 internal thread front end of cap and concordant pen tip at the corresponding position in 2 internal thread rear end of pen cap, screw thread and nib hole 11 on penholder 1 Between spacing slided for bulge loop 3.

1 rear end of penholder is detachably provided with that pen core is made to keep stable stability column 5 in writing.5 rear end one of stability column Body is provided with the tail cap 51 for preventing pen from rolling everywhere after the drops.One end far from tail cap is provided with magnet on stability column 51 6。

The above embodiments are only the preferred embodiment of the utility model, it is impossible to the right of the utility model is limited with this Range, therefore, according to the equivalent variations that present utility model application the scope of the claims is made, such as using similar technique, similar structures Equivalent product still belongs to the range that the utility model is covered.
