CN2407951Y - new mushroom rubbing device - Google Patents

Abstract

The utility model relates to a mushroom rubbing device used in print fabrication. In order to particularly solve the problems that the surface hardness of a wood mushroom is low, the abrasion can easily occur, etc., and the utility model is designed. The utility model comprises a mushroom head and a handle, wherein, the bottom surface of the mushroom head is coated with metal plates in the shape of a spherical crown, and thereby, a mushroom rubbing device with a metal jacket is formed. The utility model is a split-combined type, owing to a smooth surface, the scrape of printed paper is prevented; owing to a high surface hardness, the effect of print fabrication is increased, and lignum can be saved. The utility model has an active pushing effect on print teaching for middle and primary schools.

Description

A kind of novel mushroom is opened up

The utility model relates to a kind of student's fine arts learning aid, and the mushroom of using during specifically a kind of etching is made is opened up.

In fine arts etching works manufacturing process, plate-making arranged, roll China ink, cover paper, several steps such as mill seal.Mill seal process is exactly to print off works with the instrument mill on the seal paper of forme.Used instrument is that wooden mushroom is opened up tool, and formal name used at school claims mushroom to open up again " wood mushroom ".The wood mushroom includes mushroom head and handle two parts, is to process with hard wood turning.Because the hardness of wooden mushroom own is not very high, it is very fast to wear and tear in mill seal process, thereby the service life of wood mushroom is all very short.And new mushroom head has wood thorn at grain of wood place, can scratch seal paper during inscription rubbing, damages works.Use the steel spoon to make mill seal instrument in addition in addition, though its result of use is better than the wood mushroom, use not too smoothly, non-specific purpose tool belongs to substitute.These shortcomings had then both increased student's study costs in middle and primary schools' print teaching, strengthened student's learning difficulty again, thereby were unfavorable for carrying out very much of fine arts print teaching.

The purpose of this utility model just provides a kind of hardness height, anti abrasive novel mushroom is opened up, and etching is made and the needs of primary and secondary art print teaching to adapt to.

The utility model is achieved in that to pester to open up and still includes mushroom head and handle, is covered with spherical crown shape sheet metal in the bottom surface of mushroom head, opens up thereby make a kind of mushroom with metallic plastron.Smooth surface that this novel mushroom is opened up and hardness height, thereby wearability is good, and mill is opened up effect and also obviously is better than the wood mushroom.

The utility model also can be realized like this: mushroom is opened up be made for the branch body structure, promptly the mushroom head is a spherical crown shape housing, the housing middle part has boss, handle, at its lower end to be screwed in the centre bore of housing boss, and there is the jaw crimping at the edge of sheet metal in the groove at housing end face edge.The mushroom of branch body structure is opened up can be placed apart in custom-designed Art utensil box, thereby make things convenient for students in middle and primary schools' study to use.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

This novel mushroom is opened up, and can be improved on the basis of original wood mushroom, promptly is covered with spherical crown shape sheet metal 3 in the bottom surface of mushroom 1, and the top of sheet metal 3 stamps out jaw, embeds the top of mushroom head, or with iron nail with the jaw nail on the mushroom head.Open up with regard to the mushroom that can be made into high rigidity, high-wearing feature like this.Sheet metal can be made with steel, copper material or other metal materials.

What Fig. 1 provided is that the split type mushroom that is fit to students in middle and primary schools' use is opened up, promptly mushroom 1 and handle 2 are for dividing a body structure, mushroom 1 is a spherical crown shape housing, there is boss at the housing middle part, the lower end of handle 2 is screwed in the centre bore of housing boss, sheet metal 3 covers on the bottom surface of spherical crown shape housing 1, and sheet metal 3 upper edge are along there being jaw, and the jaw crimping is in the groove at housing end face edge.

For the overall appearance that keeps the mushroom head with prevent that jaw from starting sheet metal is come off, a gland 4 can be set on housing 1 top, gland 4 is screwed in the outside of housing boss, the gland lower edge then just in time covers in the end face of spherical crown shape housing 1 and the jaw of sheet metal 3, thereby make the mushroom head that constitutes by three parts combine handled easily and use securely.

This novel mushroom is opened up available injection molding, refills sheet metal, and combines.Detachment is placed during placement, to reduce the volume of learning aid packing box.This mushroom is opened up because smooth surface has prevented scratching of seal paper; Owing to the case hardness height, improved the making effect of etching, can save a large amount of high-quality timber simultaneously, for the print teaching of middle and primary schools, also can play positive impetus.

Claims (3)

1, a kind of novel mushroom is opened up, and includes mushroom head (1) and handle (2), it is characterized in that being covered with spherical crown shape sheet metal (3) in the bottom surface of mushroom head (1).

2, novel mushroom according to claim 1 is opened up, it is characterized in that mushroom head (1) is spherical crown shape housing, there is boss at the housing middle part, and the lower end of handle (2) is screwed in the centre bore of housing boss, and there is the jaw crimping at the edge of sheet metal (3) in the groove at housing end face edge.

3, novel mushroom according to claim 2 is opened up, and it is characterized in that being provided with gland (4) on the top of spherical crown shape housing (1), and gland (4) is screwed in the outside of housing boss, and the gland lower edge hides on housing (1).
