Abstract

The utility model relates to a rubber pen, comprising an outer tube and an inner tube. The utility model is characterized in that the tube wall of the outer tube is provided with two clamping pieces, and the inward direction of the clamping piece is provided with a convex platform. The inner tube and the outer tube are sheathed to make the convex platform of the clamping piece of the outer tube is clamped in the long hole of the inner tube. The lower part of the inner tube is provided with a clamp, and the long column-shaped rubber of the inner tube is clamped by the clamp, and the exposed length is adjusted through the pressing mode. The utility model has the advantages that the rubber pen is convenient to erase the handwriting of small area without affecting the ambient, when the rubber erasing block is run out to leave a small block, the rubber pen can be used continuously without efforts by means of the clamping force of the clamp, and after run out, the rubber pen can be replaced, so the utility model has the advantages of convenient use and material benefit.

Description

Rubber pen

The utility model relates to a kind of Rubber pen.

Known erasing rubber is generally a solid shape, square shape or various moulding bulk, and the shortcoming of this block erasing rubber is: because volume is bigger, so the wiping area is also corresponding bigger, then powerless than the writing on the small size for only needing wiping.In addition when block rubber with to an only surplus fritter time, take up very inconveniently, and feels of abandoning unfortunately.Also having another erasing rubber is lip pencil, and appearance wraps with paper bag, tears a segment table paper, exposes one section erasing rubber, tears one section after using up again.This erasing rubber uses pretty troublesome, and makes also complicated.

In view of existing shortcoming in the above-mentioned prior art, the purpose of this utility model provides a kind of novel erasing rubber, and it is easy to use, at an easy rate the writing of wiping small size.

The purpose of this utility model is achieved in that it comprises pipe in an outer tube and, the tube wall that it is characterized in that outer tube is provided with two intermediate plates, the intermediate plate inward direction has boss, have elongated hole on the tube wall of interior pipe, interior pipe bottom has several end play, make it form several holding pieces, and the outer wall of holding piece is to outer lug, interior pipe and outer tube suit, boss on the outer tube intermediate plate is stuck in the elongated hole of interior pipe, and installs a spring between the boss of interior pipe top and outer tube intermediate plate, the outside high spot of pipe bottom outer wall is stuck in the outer tube bottom in making, one long column shape erasing rubber is housed in the interior pipe, its bottom is clamped by the holding piece of interior pipe bottom, pipe top in pushing downwards with hand, and pipe moves down in making, the holding piece of bottom is thrown off the blocking of outer tube bottom and is expanded outwardly, thereby erasing rubber is released.

Also can be provided with a little groove in each holding piece inboard of interior pipe bottom, when making erasing rubber clamped, part erasing rubber material is squeezed in this little groove, by clamping more firmly, and the unlikely lubricating substance phenomenon that when wiping, produces.

Spring can not produce friction and send fricative with inner tubal wall when pushing for making, the utility model can also be established a circular groove on interior pipe top, also be provided with onesize circular groove on the boss of outer tube two intermediate plates simultaneously, the upper and lower end of spring all is installed in the groove.

The utility model adopts pen type to wipe skin and wipes, the mode that utilization is pushed is controlled its length of exposing, and only runs low when surplus a bit of at erasing rubber, still can be by the chucking power of Rubber pen, continue to use and without lifting an eyebrow, in addition because the utility model adopts is the pen type erasing rubber, thus the writing of wiping small size easily, and around not influencing, after erasing rubber of the present utility model uses up, can change, thus easy to use, and economical and practical.

The utility model is described in further detail below in conjunction with accompanying drawing, and this accompanying drawing is the structural representation of the utility model most preferred embodiment.

Fig. 1 is the outer tube cutaway view.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is interior pipe cutaway view.

Fig. 4 is the side view of Fig. 3.

Fig. 5 is the upward view of Fig. 3.

Fig. 6 and Fig. 7 are all to be general structure schematic diagrames.Figure 6 shows that the push action schematic diagram, Fig. 7 is static schematic diagram.

Fig. 8 is the schematic diagram of installing pen clip.

As shown in Figures 1 and 2, have the reverse U shape slit on two sidewalls of outer tube 10, therefore form two rubber-like intermediate plates 11 and 11 ', two intermediate plates side in pipe have boss 12 and 12 ', the while above boss, be provided with circular groove 13 and 13 '.

As shown in Figure 3-Figure 5, in have on pipe 20 two sidewalls elongated hole 22 and 22 ', the top is provided with circular groove 28 and has circular hole 21, the bottom is anchor clamps 25, its formation is to leave four axial slits 24 in the pipe lower end, thereby, being provided with a groove 26 in each holding piece inboard at four holding pieces 23 of interior pipe lower end formation, the outer wall with holding piece is provided with to outer lug 27 simultaneously.

As Fig. 6, Fig. 7, shown in Figure 8, with interior pipe 20 outer tube of packing into from the bottom of outer tube 10, and make the boss 12 and 12 of intermediate plate ' be stuck in microscler 22 of inner tubal wall, in 22 ' hole, adopt the same way as spring 31 of packing into simultaneously, and the groove 28 at pipe top and the groove 13 on the boss in the two ends up and down of spring are installed on respectively, 13 ' in, long column shape erasing rubber 33 is packed into, because holding piece outer projection 27 is stuck in outer tube bottom 32, holding piece 23 is inwardly drawn in, clamp erasing rubber, it can not be come off, and when pushing the Rubber pen top with hand, interior pipe moves down, and makes projection 27 throw off outer tube bottoms 32 and expand outwardly, and at this moment erasing rubber promptly is released, adjust the length of erasing rubber this moment or change erasing rubber and all can, unclamp after the hand of pushing, interior pipe sets back under the effect of spring force, and erasing rubber is promptly clamped again.Pen clip 35 is sleeved on the outer tube outer wall.

Claims (3)

1, a kind of Rubber pen, it comprises pipe in an outer tube and, the tube wall that it is characterized in that outer tube is provided with two intermediate plates, and the intermediate plate inward direction has boss, has elongated hole on the tube wall of interior pipe, interior pipe bottom has several end play, and the outer wall of holding piece is to outer lug, and interior pipe and outer tube suit are stuck in the elongated hole of interior pipe the boss on the outer tube intermediate plate, and spring of installing is equipped with a long column shape erasing rubber in the interior pipe between the boss of interior pipe top and outer tube intermediate plate.

2, Rubber pen according to claim 1 is characterized in that being provided with a little groove in each holding piece inboard of interior pipe bottom.
