Description

Modified elastic telescopic location pen

Technical field:

It is a kind of that the utility model relates to pen.

Background technology:

The structure of pen mainly is made up of outer sleeve, inner sleeve, proposition, nib, tracheae and barrel, between inner and outer sleeves by being threaded, proposition, nib are installed in the inner sleeve, barrel is coupled on the extending part of inner sleeve, outer sleeve must be twisted during suction, push barrel then,, draw ink by the strain of barrel.The pen structure of this structure is comparatively complicated, and use must be turned on outer sleeve, and one hand can't be operated, and therefore uses comparatively inconvenience.Extensively retrieve at the problems referred to above, still find no technical scheme related to the present invention.

Summary of the invention:

The purpose of this utility model is exactly a kind of modified elastic telescopic location pen that designs in order to solve the above-mentioned defective that exists in the prior art.

To achieve these goals, the utility model has adopted following technical scheme:

A kind of elastic telescopic location pen, it is made up of an outer sleeve and an inner sleeve that matches with outer sleeve, the inner sleeve end is provided with the sealing ring that matches with outer sleeve, the outer sleeve end is associated with proposition and nib, be associated with tracheae on the proposition, in, be provided with back-moving spring between outer sleeve, it is characterized in that the inner sleeve face of cylinder is provided with a locating slot, locating slot is joined by segment length's groove and a peach shape groove and forms, peach shape groove one end is provided with two and goes up fixed point, go up between the fixed point for two and be provided with a raised points, peach shape groove middle part is provided with a L shaped location block piece, the L shaped flex point and the elongated slot journal offset certain distance down of block piece, two end points of block piece are upward fixed a point relative with two respectively and are offset certain distance, the raised points of peach shape groove top and block piece L shaped goes up that flex point is relative and be offset certain distance, and the outer sleeve inwall is provided with lead and moves in locating slot, and with locating slot in go up and fix a point, elongated slot and L shaped block piece form the location and cooperate.The wall of inner sleeve is provided with a pore, is provided with a flexible trap that has ratchet that matches in the pore, and this valve is closed pore, opened pore when moving downward when inner sleeve moves upward.The active force of back-moving spring makes lead have a movement tendency that makes progress all the time,

The elastic telescopic location pen of said structure is no courage, and it is outer sleeve storage ink, also can be provided with the suction barrel in inner sleeve and outer sleeve.

Owing to adopted technical scheme described in the utility model, made that elastic telescopic location pen structure is greatly simple, easy to manufacture, with low cost, need only during use and press secondary gently, just ink that can draw sufficient, inner sleeve can be located in outer sleeve, and is therefore very easy to use.Valve has guaranteed that inner sleeve the time closes pore in suction, returns and opens pore on time, makes the ink of inspiration be unlikely to be extruded away.

For the utility model is described in further detail, following accompanying drawing provides two embodiment of the present utility model.

The specific embodiment:

Embodiment 1: as shown in Figure 1, locating slot 1 is made up of elongated slot 3 and peach shape groove 4, the bottom of peach shape groove 4 is respectively equipped with

fixed point

6,8, be provided with downward raised points 7 between them, be provided with opening below the peach shape groove 4 and link to each other with elongated slot 3, be provided with a L shaped block piece 5 at the middle part of peach shape groove 4, its following flex point 5a is to elongated slot 3 axis the right skew certain distance; The left end point 5b of L shaped block piece 5 and the last fixed point 6 relative certain distances that also are offset left; The right endpoint 5c of L shaped block piece 5 and the last fixed point 8 relative certain distances that also are offset left; Raised points 7 and the inboard relative certain distance that also is offset left of following flex point 5a.

Its course of work is as follows: to lower slider, after lead 2 was run in the left side of the following flex point 5a of the L shaped block piece 5 in its locating slot, lead 2 was to upper left slip under the effect of external force for inner sleeve 9, fell into fixed point 6 places, stop motion after crossing left end point 5b; Remove external force this moment, and under the effect of spring, inner sleeve 9 moves upward, and lead 2 falls into down flex point 5a and is in stable state; Apply downward external force this moment again, and peach shape groove moves downward, and the right side that lead 2 is run into raised points 7 slides into fixed point 8 places stop motion; Remove external force this moment, and under the effect of spring, lead 2 moves downward along the right side of peach shape groove 4 and enters elongated slot 3, finishes a motion process.

Modified elastic telescopic described in the utility model location pen, as shown in Figure 2, form by outer sleeve 10 and sheathed inner sleeve 9, inner sleeve 9 lower ends are provided with sealing ring 12, the lower end of outer sleeve 10 is connected with proposition 14, be connected with nib 15 in the proposition 14, the upper end of proposition 14 is connected with tracheae 11, and these all are known configurations.Be provided with a spring 13 in outer sleeve 10, its end is against on the proposition (or outer sleeve), and the other end is against on the inner sleeve, and its effect provides the elastic force that inner sleeve 9 moves upward.On the face of cylinder of inner sleeve 9, be provided with locating slot 1, its structure as shown in Figure 1, the inwall of outer sleeve 10 is provided with lead 2, it match with locating slot 1 location situation as shown in Figure 1, mistake described above.Fig. 2 is that the lead 2 in the outer sleeve 10 is positioned at the inboard location of L shaped block piece, be in contraction state, when to pressing down inner sleeve 9, and then when unclamping, under the effect of spring, lead 2 will move to the elongated slot lower end along peach shape groove and elongated slot, inner sleeve 9 is in extended configuration, as shown in Figure 6, be in negative pressure state in the outer sleeve 10 this moment, and ink enters in the outer sleeve by proposition; Push inner sleeve 9 once more downwards, 2 L shaped block piece inboards that enter in the locating slot along elongated slot of lead are in stable state.Be provided with a notch cuttype pore 9a on the top of inner sleeve 9, as shown in Figures 2 and 3, be provided with the flexible trap 16 that one one end has ratchet 16a among the pore 9a, shown position is that inner sleeve 9 is in the contraction lock-out state, the flexible circular arc portion of valve 16 contacts with the outer sleeve inwall, make the pore 9a of opposite side sealing inner sleeve 9 of valve 16, make the ink can not be excessive.Be in the stretching process at inner sleeve 9, owing to be in negative pressure state in the inner sleeve 9, valve 16 is sealed porosity 9a also; After inner sleeve 9 full extension were filled ink, as Fig. 6, shown in Figure 8, to pressing down inner sleeve 9, unnecessary air then backed down valve 16 and discharges from pore 9a, is in the lock state up to inner sleeve 9.

Embodiment 2: as shown in Figure 7, its structure is identical with embodiment 1, unique difference is to connect on the proposition 14 a suction barrel 17, when pressing inner sleeve 9 downwards, outer sleeve 10 internal pressures increase, thereby compression suction barrel 17, after discharging inner sleeve 9, under the effect of spring, inner sleeve 9 moves upward, be in negative pressure state in the outer sleeve 10, the barrel 16 that then absorbs water expands, thereby suctions ink, presses inner sleeve 9 at last downwards slowly, unnecessary air in the inner sleeve 9 is discharged in valve and pore, and inner sleeve 9 is also located in the locating slot in outer sleeve 10.
