Abstract

The utility model relates to a special painting roller for a print of an art utensil in middle and primary schools. The utility model comprises a handle, a bracket and a painting roller main body, wherein, the painting roller main body is designed into a cylindric shape by using rubber, and blind holes are arranged at the centers of both end surfaces at both ends of the painting roller main body. The blind hole is fixedly provided with air vents, both ends of a support frame are bended into right angles, and corners are provided with reinforcing ribs. The inner sides of two end sockets of the support frame are respectively extended out of a bulge, and the bulge is movably connected with the holes arranged on two end surfaces at both ends of the painting roller main body. The handle is arranged on the top surface of the support frame, and the joint of the handle and the top surface of the support frame is also provided with reinforcing ribs. The utility model has the advantages of simple structure, flexible and convenient use, fastness, durability, and strong practicability.

Description

Primary and secondary art learning aid etching special oil is rolled

The utility model relates to primary and secondary art class and uses learning aid, is meant that especially a kind of etching special oil rolls.

Fine arts lessons is the required art education course of of China nine-year compulsory education students in middle and primary schools, it is a course that practicality is very strong, the study of multiple lessons such as students in middle and primary schools will paint on fine arts lessons, technology, the fine arts learning aid of required usefulness and its kind of material, specification and use amount all have special requirement.As needing special-purpose oil to roll in the etching study, and do not have this type of special-purpose learning aid in the print teaching in the past, come inconvenience for student's etching learning tape.

The purpose of this utility model is to provide a kind of oil of the students in middle and primary schools' of being exclusively used in etching study to roll, to remedy the defective in the print teaching.

A kind of primary and secondary art learning aid etching special oil that the utility model provides is rolled, include handle, support and oil and roll body three parts formation, described oil rolls body and is made cylindrical by rubber, its end face center, two ends has the hole, the support two ends are bent into the right angle, a protuberance is respectively extended in its two ends inboard, and this protuberance rolls the hole flexible connection that body two ends end face is offered with oil, and the cradle top surface center is provided with one handle.

Technique scheme can also further realize by following detail.

Support and handle in the utility model are made one by engineering plastics, and the junction of handle and cradle top surface is provided with reinforcement, and inboard, turning, support two ends also is provided with reinforcement.It is blind hole that oil rolls the hole of offering at end face center, body two ends, is equiped with core on this blind hole.

Advantage applies of the present utility model is in the following areas: 1. simple in structure, very easy to use, practical; 2. owing to being equiped with core on the blind hole of rolling the body two ends at oil, when the use oil that rolls rolls, after the protuberance of both sides, support lower end inserts blind hole, promptly can directly not contact hole wall, make the billowing dynamic resistance of oil very little, it is flexible to guarantee on the one hand to roll, on the other hand again not reason rub off rubber powder; 3. because of inboard, turning, support two ends is provided with reinforcement, the ambassador's deformation of timbering of having avoided exerting oneself, the protuberance that causes the support lower end comes off out from oil rolls the hole at two ends; 4. cradle top surface and handle junction also are provided with reinforcement, have increased the bonding strength of handle and cradle top surface.

Below by the explanation of embodiment and conjunction with figs., design feature of the present utility model and the effect that reached are described in detail.

Fig. 1 rolls the combining structure schematic diagram for primary and secondary art learning aid etching special oil.

The supporting structure schematic diagram that Fig. 2 rolls for primary and secondary art learning aid etching special oil.

The oil that Fig. 3 rolls for primary and secondary art learning aid etching special oil rolls the body construction schematic diagram.

Above-mentioned number in the figure explanation:

The 1-handle

2-support 21-protuberance 22-reinforcement 23-reinforcement

3-oil rolls body 31-core

See also above-mentioned each figure, present embodiment provides a kind of primary and secondary art learning aid etching special oil to roll, this oil agglomeration is drawn together handle 1, support 2 and oil and is rolled body 3, handle 1 and support 2 are injection molded into one by engineering plastics ABS, handle 1 is provided with reinforcement 22 with support 2 end face junctions, support two ends corner inboard also is provided with reinforcement 23 simultaneously, it is firmly excessive when this reinforcement can effectively prevent to use, cause deformation of timbering, the protuberance 21 of support lower end rolls the blind hole at body 3 two ends slippage from oil and comes out, or too concentrated because of support corner stress, make the support fracture.Oil rolls body 3 and is made by rubber, and its two ends end face offers blind hole, penetrates wherein for the protuberance 21 of support lower end, and for preventing this protuberance direct friction hole wall, the rubber powder that rubs off drops out, and the picture of making dirty is equiped with core 31 on this blind hole.Support of the present utility model and oil rolled in when assembling, only need exert oneself slightly, by the toughness of plastics self protuberance 21 of support 2 lower ends were inserted in the blind hole that oil rolls body 3 and can finish assembling.
