Abstract

A plastic eyelet is provided to prevent damage of fabrics by corrosion, and to make it impossible to be voluntarily separated after being connected by a simple press work. A plastic eyelet includes: a female part(10) having pin holes(11) with a projection rim(14), and locking pins(12) formed between the pin holes; and a male part(20) having pin bodies(21) with a point part(22) inserted into the pin hole of the female part, and other locking pins formed between the pin bodies to be alternately positioned against the locking pins of the female part. When pressing the pin body of the male part, a crushed part of the pin body is filled into the projection rim of the female part.

The present invention relates to an eyelet, and in particular, even when injection molded from plastic, it is possible to combine female and female parts by simple pressurization when using as an eyelet, and can be fixed to be impossible to be separated arbitrarily in a combined state. It is.

Most eyelets currently used are upper and lower portions of the penetrated hole 110 in order to prevent damage to the fabric paper 100 when the connecting string (not shown) is used in connection with the hole 110 penetrated through the fabric paper 100 or the like. When the arm arm 10 and the male part 20 are coupled to each other and prevent the damage of the hole 110 penetrated through the fabric paper 100 and the like, when the connecting strap is connected, the design of the fabric paper 100 may be prevented and the design may be excellent. It is used in the case.

However, most of these things were used only as a metal material to maintain the shape of the deformed by pressing the combination of the arm portion 10 and the male portion 20 that constitutes the eyelet by a post-processing, such as a press.

However, the disadvantage of the metal material is that corrosion is caused by moisture, and in order to prevent such corrosion, various additional processing such as plating is required, and in particular, such corrosion causes damage to fabric paper.

In addition, due to the nature of the metal, the sharpness of the cutting surface requires separate processing such as polishing, and it is impossible to maintain the same planar state by the combination of the arm and the male, and also post-processing such as plating processed to prevent corrosion. Because of the corrosion caused by the moisture was not possible to use in various forms, but there was a disadvantage that is not economical.

Accordingly, the present invention is to provide an eyelet that is separated by male and female by injection molding by plastic injection molding using a characteristic of polyethylene (PE) which is soft and has excellent moldability.

To this end, between the pin part having a locking pin formed between the pin hole having a stepped frame and the pin body having a pointed portion fitted to the pin hole, and another locking pin which is positioned to be staggered with the locking pin of the female part. Consists of a male part to press the pin body of the male part to be filled in the stepped portion of the arm to simplify the implementation.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the same reference numerals are used for the same configuration as the conventional configuration.

First of all, the plastic used in the present invention uses low density polyethylene, and the low density polyethylene is produced by heating at a high pressure of 1,000 atm and 200 ° C. or higher using a small amount of air as a catalyst, and thus, generally referred to as high pressure polyethylene. Its density is about 0.91, its branches are not enough, and its crystallization is about 65%, so it becomes soft and stretches well.The tensile strength is slightly small, but the impact resistance is large, and it is easy to process and easy to use. .

As shown in FIG. 1, the low density polyethylene resin is molded by injection molding, and a plurality of pinholes 11 having respective stepped edges 14 are formed on one surface of which a hole 13 is formed in the center thereof. The pinhole 11 is formed through the corresponding other surface, the other side of the pin hole 11 between the arm portion 10 is formed with a locking pin 12 of the shallow height and the pin hole 11 formed on the other surface of the arm portion 10 Between the pin body 21 and the pin body 21 formed with the pointed portion 22 to be inserted into) another locking pin 23 which is positioned to be staggered with the locking pin 12 of the arm portion 10 It is formed, the configuration consists of a male portion 20 is formed with a partition wall 24 extending upwardly protruding in the hole 25 penetrated in the center.

At this time, by pressing the pin body 21 of the male part 20 so as to be filled in the stepped frame 14 of the arm part 10, it is simply to implement and this filling is to the characteristics of polyethylene (PE) Is made possible.

At this time, the position of the locking pins 12, 23 is to be positioned in a direction diagonal to each other to prevent the flow in the state fitted to the cloth.

At this time, the pin body as shown in Figure 4, the tip 22 of the tip is sharp and as the thick end is formed to go to the rear end to be curved to form a good support force when bonded to the fabric and at the same time does not bend when pressed The affected part is correct.

Therefore, after inserting the partition wall 24 of the male part 20 into the hole 110 perforated in the fabric 100, the fabric 100 using the pointed part 22 of the pin body 21 of the male part 20 is fixed. When the pin hole 21 of the arm part 10 is inserted into the pin body 21 and the pin body 21 is pressed, the male part 20 and the arm part 10 are in close contact with each other. At the same time, the pin body 21 is squeezed to fill the stepped frame 14 of the pinhole 11 of the arm part 10 and the arm part 10 and the male part 20 are tightly coupled and fixed, and at the same time the arm part 10 The fabric 100 is firmly fixed by the locking pins 12 and 23 of the male part 20.

Therefore, since it is molded of plastic, there is no corrosion and no damage occurs even when bonded to any fabric. Also, since it is plastic, no damage occurs even when washing. While being filled in the chin of the arm part is to prevent the random fall.

Claims (2)

A pin body 21 having a female portion 10 having a locking pin 12 formed between the pinhole 11 having a stepped frame 14 and a pointed portion 22 fitted into the pinhole 11 of the female portion 10; The pin body of the male part 20 is composed of a male part 20 in which another locking pin 23 is formed between the pin body 21 and the locking pin 12 of the female part 10 to be staggered. A plastic eyelet, characterized in that by pressing the (21) to be filled in the stepped frame 14 of the arm portion (10). The plastic eyelet according to claim 1, wherein the pointed portion (22) of the tip of the male portion is sharp and curved to form a thick flesh while going to the rear end thereof.
