Abstract
The invention discloses an ejection pen which comprises a pen refill and a pen sleeve. The pen refill is arranged in the pen sleeve in a penetrating manner in the axial direction of the pen sleeve through a set of ejection mechanism. The tail end of the pen sleeve is of an open cone structure. A locating ring is arranged in the cone structure. The ejection pen is characterized in that a longitudinal groove is formed in the locating ring, and a protrusion matched with the groove in shape is arranged on the outer wall of the pen refill; and the locating ring is arranged in the cone structure of the tail end of the pen sleeve, the groove in the surface of the locating ring and the protrusion on the outer wall of the pen refill are matched for calibrating and locating, and equipment damage is avoided.
Description
Technical field
The present invention relates to an a kind of tool.
Background technology
The formula tool that launches or propel of selling on the market at present is generally all used by a pushing mechanism pushing pen refill.But, because pen core generally processes when dispatching from the factory, there is defect, or impact in use, cause its surface curvature, make pen core head in its push to the extruding of pen cap one end, easily cause pen cap end to damage, affect service life
Summary of the invention
The object of this invention is to provide one and launch pen, in the vertebral body structure of pen cap end, be provided with locating ring, carry out calibration by the male cooperation on the fluting on its surface and pen core outer wall and locate, avoid device damage.
The one that the present invention proposes for its technical problem of solution launches pen, comprise pen core, the pen cap, described pen core is axially arranged in the pen cap by one group of ejection mechanism along the pen cap, described pen cap end is the vertebral body structure of opening, locating ring is provided with in described vertebral body structure, locating ring is provided with longitudinal fluting, and pen core outer wall is provided with the projection of closing 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, is calibrated by locating ring, absorption pressure, avoids damaging the pen cap.
Locating ring adopts elastomeric material to make, and be convenient to absorption pressure, be arranged in the draw-in groove of vertebral body structure, the fluting on its surface is set to some groups of subtend, and described groove width, wider than the height of pen core rat, avoids boss failure locating ring.
Described ejection mechanism comprises Compress Spring and stick harness, by the setting of Compress Spring, make a tool when use or non-working condition, Compress Spring is all in compressive state, and when changing pen core, pen cap top is opened, the reverse pushing pen refill of Compress Spring ejects, remove from generally adopt on the market pour out mounting means, part is still installed on pen cap inside, makes simple installation.
Described stick harness surface is arranged with snap ring, has the radial tip hole by the stick harness center of circle, fix for pen core in the middle part of described snap ring, by stick harness Compress Spring, makes tool Compress 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 by the Compress Spring on mobile link locating ring top, and positioner is generally limit fastener, and profit is stuck with buckle Compress 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, is convenient to open change pen core.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of ejection mechanism of the present invention
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the present invention further.
As shown in Figure 1, one launches pen, comprise pen core 1, the pen cap 2, described pen core 1 is axially arranged in the pen cap 2 by one group of ejection mechanism along the pen cap 2, the described pen cap 2 end is the vertebral body structure 3 of opening, be provided with locating ring (not shown) in described vertebral body structure, locating ring is provided with longitudinal fluting, and pen core 1 outer wall is provided with the projection of closing with described fluting matching form.
Locating ring adopts elastomeric material to make, and be arranged in the draw-in groove of vertebral body structure 3, the fluting on its surface is set to some groups of subtend, and described groove width is wider than the height of pen core 1 rat.
Described ejection mechanism comprises Compress Spring 5 and stick harness 7;
Described stick harness 7 surface is arranged with snap ring, has the radial 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 by the Compress Spring 5 on mobile link locating ring top.
The knob 4 of ejection mechanism can be opened in the top, one end of pen core 1, and described knob 4 is arranged at the top of the pen cap 2 by helicitic texture.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
