Abstract

The utility model discloses a health-care eraser, comprising a socket, a sleeve pipe, an up-down inner sleeve, a cover, an eraser and absorbent cotton. An eraser (6) is arranged at the upper part of an up-down inner sleeve (4); the up-down inner sleeve (4) is sheathed with a sleeve pipe (3); the inner part of an annular notch on the outer circle of the sleeve pipe (3) through an inner protruding table (2) is clamped on a socket (1); internal threads on the base (1) and external threads of the up-down inner sleeve (4) are matched; the outer sleeve of the sleeve pipe (3) is equipped with a cover (5); the inner part of the bottom of the cover (5) is equipped with absorbent cotton (7) ; the base (1) is rotated and through the matching between the internal and external threads, the up-down inner sleeve (4) can be up-down and guided by matching between a slider (8) and a slid slot (9); the absorbent cotton can make the head of the eraser wet. The utility model has the advantages of hygiene, convenient operation, high utilizing rate for the eraser and health-care to the health of the users; therefore, the utility model is suitable both to the students and to the delineators.

Description

Healthy erasing rubber

Technical field: the utility model relates to erasing rubber, particularly a kind of healthy erasing rubber.

Background technology: erasing rubber of the prior art does not generally have external packing, appearance is easily contaminated, the student is when doing one's assignment, some mistakes can occur unavoidably,, wrong mark be wiped with erasing rubber in order to keep scope of operation cleaning, neat, in order to wipe totally, what have puts in erasing rubber libation at an ancient wedding ceremony saliva wiping in the mouth, infects bacterium easily, to healthy unfavorable.What have also wipes with inner sealing formula screw rod expanding rubber, and this structure is at the erasing rubber open interior screw drive to be installed, and the utilization rate of erasing rubber is low, should not adopt.

Summary of the invention: the purpose of this utility model is to provide a kind of healthy erasing rubber, this erasing rubber lifting freely, automatic libation at an ancient wedding ceremony water, good airproof performance can reach the purpose of using health.

Formation of the present utility model:, form by pipe, lid, erasing rubber and absorbent wool in base, sleeve pipe, the lifting, erasing rubber 6 is installed in the upper end of cover 4 in the lifting, cover tubing 3 on the cover 4 in lifting, clamp base 1 by inner convex platform 2 in the annular groove on sleeve pipe 3 cylindricals, external screw thread in internal thread on the base 1 and the lifting on the cover 4 cooperatively interacts, and is with outside sleeve pipe 3 and covers 5.

Cover 4 is cylindrical shapes in the lifting, has annular inner convex platform, cylinder that the slide block 8 of two symmetries is arranged in the cylinder of upper end outward, on the cylindrical of bottom external screw thread is arranged.

Sleeve pipe 3 is cylindrical shapes, and the vertical chute 9 of two symmetries is arranged in the cylinder, on the cylindrical of bottom annular groove is arranged.

Base 1 is a drum shape, and annular inner convex platform 2 and internal thread are arranged in bung.

Lid 5 is drum shapes, and absorbent wool 7 is housed at the bottom of the bucket.

Compared with the prior art, the utility model utilizes cover and the guiding of sleeve pipe and the screw thread transmission lifting of interior cover of lifting and base in the lifting, the utilization of the encapsulation of lid and lid end absorbent wool, make the erasing rubber health, freely easy to use, erasing rubber utilization rate height helps user's health.

Description of drawings: accompanying drawing is the utility model structural representation.

Among the figure 1, base, 2, inner convex platform, 3, sleeve pipe, 4, cover in the lifting, 5, lid, 6, erasing rubber, 7, absorbent wool, 8, slide block, 9, chute.

The specific embodiment: as shown in the figure, erasing rubber 6 is installed on the annular inner convex platform of cover 4 upper ends in the lifting, overlap tubing (3) on the cover 4 in lifting, the slide block 8 of two symmetries is arranged on the cylindrical of cover 4 in the lifting, slide block 8 cooperates with the vertical chute 9 of sleeve pipe 3 interior two symmetries.On the cylindrical of sleeve pipe 3 lower ends, annular groove is arranged, in groove, clamp base 1 by inner convex platform 2, external screw thread in internal thread on the base 1 and the lifting on the cover 4 cooperatively interacts, rotating base 1 erasing rubber 6 is stretched out or indentation sleeve pipe 3 in, lid 5 is drum shapes, absorbent wool 7 is housed at the bottom of the bucket, and lid 5 is sleeved on the cylindrical of sleeve pipe 3.
