Description

A kind of Simple pen
Technical field
The utility model relates to a kind of pen.
Background technology
Disclosed about in the prior art of pen in the market, generally comprise penholder, pen core and establish the cap for brush and do not establish two kinds of the cap for brush.Not establishing the pen of cap for brush major part to press pressure device by arranging at penholder afterbody, realizing pen core in the conversion using and do not use two states by coordinating spring or rotating upper lower pen rod by dislocation.Be positioned at the pen core of the hollow inner side of upper penholder and lower pen rod in order to fixing pen core, upper penholder inside top generally has the securing member for fixing pen core, and pen core top is fixing in the fasteners; And be adopt screw thread socket to realize between upper penholder and lower pen rod.General pen is also furnished with the cap for brush, to realize blocking protection when not using to pen core nib.
Summary of the invention
Utility model object of the present utility model is to provide a kind of pen not establishing the cap for brush or spring structure, and in use, still can realize making the head of pen core expose for writing, when not using, the head of pen core is hidden and is convenient for carrying this pen.
In order to realize foregoing invention object, the utility model have employed following technical scheme:
A kind of Simple pen, comprises the front pen container of hollow, the rear pen container of hollow and pen core; Pen core is arranged in the hollow inner side of front pen container and rear pen container, and the rear end, inner side of rear pen container is also fixed with the securing member for fixing pen core, and pen core rearward end is fixing in the fasteners; The outer wall at front pen container rear portion is provided with the limited impression of ring-type, and the inwall of rear pen container front end is provided with collar flange, and the front portion of rear pen container is socketed on the outer wall at front pen container rear portion, and collar flange is positioned at limited impression; Described limited impression forms by being positioned at anterior first ring connected in star, second annular groove at middle part and the 3rd annular groove at rear portion; Described first ring connected in star and the 3rd annular groove all with described collar flange tight fit; Described second annular groove and described collar flange loose fit.
As preferably, described securing member is the cylinder of opening towards front side, and the opening of securing member is positioned at inside rear pen container; The inside of described cylinder is provided with the shoulder hole for tight fit different size pen core; Axially when the front pen container of opposing stretching and rear pen container, collar flange can form interference fit, until deviate from described front pen container outer wall after departing from from limited impression rear end.
As preferably, described first ring connected in star and the second annular groove connection are by cambered surface transition; Second annular groove and the 3rd annular groove connection are also by cambered surface transition.
Have employed the Simple pen of technique scheme, compared with existing pen, it has following beneficial effect:
One, this Simple pen coordinates by being mutually socketed between front pen container with rear pen container, can be slidably connected the length changing whole penholder between front pen container and rear pen container within the specific limits, thus realizes exposing and hiding of nib in pen core.
Two, the utility model realizes exposing of nib in core by front pen container, rear pen container and pen core three parts and hides, front pen container and rear pen container structure simply novel, parts are few, and cost is low, stability and durability good.
Three, the limited impression in front pen container of the present utility model is made up of the 3rd annular groove at the first ring connected in star of front portion, second annular groove at middle part and rear portion, only there is in front pen container the architectural feature of above-mentioned limited impression, all can be realized by outer processing, easy to process, machining accuracy is high, and processing cost is low.
In a word, because this Simple pen does not have the cap of traditional pen or a spring structure, therefore, this pen have structure simple novel, use stable, the advantage of grade easy to carry, has enriched kind and the playability of pen.
Accompanying drawing explanation
Fig. 1: in the utility model embodiment, nib is in the Simple pen cross-sectional view of hidden state.
The partial enlargement structural representation at A place in Fig. 2: Fig. 1.
Fig. 3: in the utility model embodiment, nib is in the Simple pen cross-sectional view exposing state.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment: a kind of Simple pen as Figure 1-3, comprises the front pen container 2 of hollow, the rear pen container 3 of hollow and pen core 1.Pen core 1 is arranged in the hollow inner side of front pen container 2 and rear pen container 3, and the rear end, inner side of rear pen container 3 is also fixed with the securing member 31 for fixing pen core, and pen core 1 rearward end is fixed in securing member 31.
The outer wall at front pen container 2 rear portion is provided with the limited impression 20 of ring-type, and the inwall of rear pen container 3 front end is provided with collar flange 30, and the front portion of rear pen container 3 is socketed on the outer wall at front pen container 3 rear portion, and collar flange 30 is positioned at limited impression 20.Due to the existence of this limited impression 20, after front pen container 2 and rear pen container 3 are socketed mutually, even if operator is when axially certain little strength is bestowed in opposing stretching, be also difficult to directly be pulled open separation.
The state of not writing exposed the state of writing or be in nib hiding being in nib in order to ensure pen core 1 is all more stable, therefore the utility model, limited impression 22 is made up of the 3rd annular groove 20c at the first ring connected in star 20a of front portion, the second annular groove 20b at middle part and rear portion.First ring connected in star 20a and the 3rd annular groove 20c respectively with collar flange 30 tight fit, and the second annular groove 20b and collar flange 30 loose fit, therefore, when nib expose write state time, collar flange 30 is tightly stuck on first ring connected in star 20a, and when the state of not writing that nib is hidden, collar flange 30 is tightly stuck on the 3rd annular groove 20c.
In the utility model, above-mentioned securing member 31 is the cylinder of opening towards front side, and the opening of securing member 31 is positioned at inside rear pen container 3.The inside of cylinder is provided with the shoulder hole 311 for tight fit different size pen core 1, and after only having pen core 1 fixing by securing member 31, it is movable that front pen container 2 and the relative motion of rear pen container 3 just can not drive together with pen core 1.
When imposing on the axial front pen container 2 of opposing stretching of larger strength and rear pen container 3, the collar flange 30 on rear pen container 3 can form interference fit with front pen container 2 outer wall, until deviate from, but not damage front pen container 2 and rear pen container 3 after departing from from limited impression 20 rear end.
In order to use better, above-mentioned first ring connected in star 20a and the second annular groove 20b connection are by cambered surface transition; Second annular groove 20b and the 3rd annular groove 20c connection are also by cambered surface transition.
Above embodiment illustrates by way of example, and it can not as to restriction of the present utility model.When not deviating from the utility model scope, its principal character may be used for various embodiment.
