Description

a grate

technical field

The utility model relates to a grate, in particular to a combined grate.

Background technique

The traditional grate is a combing utensil made of bamboo and ox bone, with a beam in the middle and dense teeth on both sides. The grate has both practical and symbolic functions. On the one hand, because the teeth of the grate are denser, it can be used to scrape dandruff and lice hidden in the hair; role.

The manufacturing process of the traditional grate is meticulous and complicated, and there are many processes, requiring 108 "hands and feet". The process is mainly divided into the following steps: ① making blanks, selecting suitable bamboo, opening the green grate bamboo slices with a grate knife, peeling off the green skin, drawing creases on the remaining bamboo slices to form a ratio, and using red and yellow Natural things such as bamboo and green are used as dyes, boiled for dyeing, and then the ratio is folded into a certain length according to the crease to obtain teeth, and the teeth are tied with thin wires to form blanks; , sawed into knots, broken into blocks, and cut into widths and narrows according to a certain pattern to obtain beams; ③ to make stalls, choose beef bones with particularly good toughness as raw materials, saw them into knots according to the standard length of the teeth, and then saw them into small pieces with a width of one centimeter. , and finely polished to obtain the shelf; ④ Install the shelf made in step ③ on both ends of the blank obtained in step ① to obtain the hall. ⑤The tangzi obtained in step ④ is processed by "cutting the tangzi" and "filling the tangzi", and then using special beef glue to bond the tangzi to the beam from both sides to complete the production of the grate. Some high-end grates are still used to make a fuss on the narrow and long beams, or poems or paintings, or books or engravings, forming a major feature of arts and crafts. Traditional grates are generally produced in small workshops based on family units due to the complicated and detailed craftsmanship, and it is difficult to expand the scale and increase output. In addition, it can be seen from the above structure that the adjacent grate teeth of the traditional grate are closely attached together. Although there is a certain gap between the teeth tips of the grate teeth, it is often difficult for people with thick hair to comb hair.

Chinese patent document CN 2715597Y (Application No. 200420059565.9) discloses a multifunctional comb with a mosaic structure. The comb in this document includes a comb beam and comb teeth, and a concave groove is opened at the bottom of the comb beam. One structure is : the comb teeth are composed of several individual comb tooth bars, and the upper parts of the comb teeth are respectively provided with convex joints. The joint part is all hidden in the slot; another structure is: the comb teeth are made in one piece, the upper joint part of the comb teeth is provided with expansion joints, and fillers are arranged in the expansion joints, and the comb teeth are pressed together through the joint part Set in the slot on the lower part of the comb beam.

The manufacturing method of the above-mentioned comb has been simplified a lot compared with the traditional craft, but for the comb teeth with several individual comb rack structures, each comb tooth must be equipped with a curved, trapezoidal, rib-shaped or streamlined joint, and the working The amount is still quite a lot; and for the structure made of comb teeth in one piece, the matching method between the comb teeth and the beam is relatively simple, and we need to further propose a grate structure with simple process and various changes.

The mounting groove 12 is arranged at the left-right central part of the front part of the handle body 11. The mounting groove 12 is a groove with left and right groove walls on the handle body 11. The cross-section of the mounting groove 12 is rectangular. The width of the installation groove 12 is 1.5mm～2.5mm, and the depth is 3mm～8mm; The distance between the right ends of the front end surfaces of the handle main body 11 is 5 mm to 25 mm.

The grate tooth member 2 is formed by arranging each grate tooth 22 in a row, and the left-right length of the grate tooth group is the same as the length of the installation groove 12 . The width of each grating tooth 22 is the same as the width of the installation groove 12, and the tip of the grating tooth 22 in contact with the scalp is curved, and the tooth spacing between adjacent grating teeth 22 is 0.05 mm to 0.3 mm. The thickness of root grate tooth 22 is 0.5mm～1mm.

Insert the tail end of the grating tooth 22 into the mounting groove 12 as the root of the grating tooth member (2), and bond the end of the grating tooth 22 in the mounting groove 12 with an adhesive to obtain a grate. The distances between the left and right ends and the left and right ends of the front end of the handle 1 are respectively 5 mm to 25 mm, so there is no stop bar at the end of the grate 22 and there will be no force on the hand when the grate 22 bounces to one side and bounces back Therefore, the processing procedure of the grate is greatly simplified. Certainly, the end portion of ricochet 22 still can be provided with retaining bar.

The shape of the handle 1 of the grate can have various changes, it can be the arc shape of the present embodiment, it can also be a rectangle (Figure 13), a fan shape (Figure 14), other shapes such as flying birds, insects and fish, etc., to ensure that the handle main body 11 is provided with the position that installs groove 12 to get final product.
