Description

One launches pen

Technical field

This utility model relates to a kind of pen tool.

Background technology

The formula pen tool that launches or propel sold on the market at present is typically all used by a pushing mechanism pushing pen refill.But, typically process when dispatching from the factory due to pen core and there is defect, or impact in use, cause its surface curvature so that it is in push, pen core head extrudes to pen cap one end, be easily caused pen cap end and damage, affect service life

Utility model content

The purpose of this utility model is to provide one and launches pen, is provided with locating ring in the cone structure of pen cap end, carries out calibration location by the fluting on its surface and the male cooperation on pen core outer wall, it is to avoid device damage.

The one that this utility model is proposed by its technical problem of solution launches pen, including pen core, the pen cap, described pen core is axially arranged in the pen cap along the pen cap by one group of ejection mechanism, described pen cap end is the cone structure of opening, it is provided with locating ring in described cone structure, locating ring is provided with longitudinal fluting, and pen core outer wall is provided with the projection closed with described fluting matching form.In use, ejection mechanism moves down, and high spot snaps in fluting, and pen core knee props up locating ring, locating ring calibrates, absorption pressure, it is to avoid damage the pen cap.

Locating ring use elastomeric material make, it is simple to absorption pressure, be arranged in the draw-in groove of cone structure, the fluting on its surface be set to to some groups, described groove width is wider than the height of pen core rat, it is to avoid boss failure locating ring.

Described ejection mechanism includes compression spring and stick harness, by the setting of compression spring, make pen tool when use or non-working condition, compression spring is in compressive state, and when changing pen core, pen cap top is opened, the reverse pushing pen refill of compression spring ejects, removing the most commonly used mounting means of pouring out from, part is still installed on inside the pen cap, makes simple installation.

Described stick harness surface is arranged with snap ring, has the radial direction tip hole by the stick harness center of circle, fix for pen core in the middle part of described snap ring, by stick harness compression spring, makes pen tool compression spring when non-working condition be in compressive state；

The body of rod of described pen core is provided with positioner, and described positioner can be by the compression spring on mobile link locating ring top, and positioner is generally limit fastener, and profit is stuck with buckle compression spring one end.

The knob of ejection mechanism can be opened in the top, one end of pen core, and described knob is arranged at pen cap top by helicitic texture, it is simple to opens and changes pen core.

Fig. 2 is the structural representation of ejection mechanism of the present utility model

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with diagram and specific embodiment, this utility model is expanded on further.

As shown in Figure 1, one launches pen, including pen core 1, the pen cap 2, described pen core 1 is axially arranged in the pen cap 2 along the pen cap 2 by one group of ejection mechanism, the described pen cap 2 end is the cone structure 3 of opening, being provided with locating ring (not shown) in described cone structure, locating ring is provided with longitudinal fluting, and pen core 1 outer wall is provided with the projection closed with described fluting matching form.

Locating ring use elastomeric material make, be arranged in the draw-in groove of cone structure 3, the fluting on its surface be set to to some groups, described groove width is wider than the height of pen core 1 rat.

Described ejection mechanism includes compression spring 5 and stick harness 7；

Described stick harness 7 surface is arranged with snap ring, has the radial direction tip hole by the stick harness center of circle in the middle part of described snap ring, fixes for pen core 1；

The body of rod of described pen core 1 is provided with positioner 6, and described positioner 6 can be by the compression spring 5 on mobile link locating ring top.

The knob of ejection mechanism can be opened in the top, one end of pen core 1, and described knob is arranged at the top of the pen cap 2 by helicitic texture.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
