Abstract
The utility model relates to a dust-removing chalk sleeve, which comprises a columnar sleeve body with an open end. A screen layer is arranged on the inner wall of the columnar sleeve body. Screw holes are symmetrically arranged on the external surface of the columnar sleeve body. Screws are arranged in the screw holes. The dust-removing chalk sleeve has the advantages that the structure is simple, a user is prevented from directly touching chalk by using the sleeve body to hold a chalk body, dust can be effectively absorbed by using the screen layer arranged in the chalk sleeve, and an effect of dust removal is reached. The dust-removing chalk sleeve is particularly suitable for schools.
Description
One, technical field
The utility model relates to the realia field, especially a kind of dust-removing powder pen cap.
Two, background technology
The chalk that teachers ' teaching uses is made as lime material, teacher and every day is easy to hinder hand when using, and in addition, dust can be bonded on the chalk body when writing with chalk word, and is very unhygienic.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, avoids hindering the dust-removing powder pen cap of hand.
The utility model solves the technical scheme that the prior art problem is adopted: a kind of dust-removing powder pen cap, the cylindricality body that comprises an end opening, inwall at described cylindricality body is provided with gauze layer, is provided with screw in the outer surface symmetric position of described cylindricality body, is provided with screw in the described screw.
The slightly larger in diameter of described cylindricality body is in the maximum gauge of chalk.
The beneficial effects of the utility model are: the utility model is simple in structure, by body the chalk body is entangled, and has avoided the user directly to contact chalk, and utilizes the gauze layer that is provided with in the chalk sleeve effectively to adsorb dust, reaches the effect of dedusting.The utility model is specially adapted to school.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
Below in conjunction with specific embodiment the utility model is described:
As shown in Figure 1, a kind of dust-removing powder pen cap comprises the cylindricality body 1 of an end opening, is provided with gauze layer 2 at the inwall of cylindricality body 1, is provided with screw in the outer surface symmetric position of cylindricality body 1, is provided with screw 3 in the screw.The slightly larger in diameter of cylindricality body 1 is in the maximum gauge of chalk 4.
During actual the use, the user puts into cylindricality body 1 with chalk 4, and utilize screw 3 that chalk 4 is fixed, because the slightly larger in diameter of cylindricality body 1 is in the maximum gauge of chalk 4, therefore leave certain slit at cylindricality body 1 and 4 in chalk, when writing, 1 surface has avoided hand to contact with the direct of chalk 4 thereby the user contacts the cylindricality body, the dust that falls into the slit simultaneously can be collected by the gauze layer 2 of cylindricality body 1 inwall, reduced dust from flying.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
