Abstract

The present invention provides a key for injecting gas into pair glass, which can completely block a leakage of gas charged in advance when gas is injected, without using a component of a complex structure such as an existing ejector, and has a simple structure. The key (10) includes an injection port (23) for injecting the gas by being connected to a spacer (102) between the pair glass. The key (10) includes: a combining unit (11) individually combined with the two spacers connected to each other; and a connection unit (21) installed between the combining units (11). The connection unit has the injection port (23), and the injection port (23) includes a sealing member (20) sealing the injection port (23) and formed of elastic rubber to enable a gas injection needle (60) to tightly pass therethrough.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key for injecting gas between two-layered glass and a method of manufacturing the same, and more particularly, to a key having an inlet for injecting a gas, which is connected to a spacer between two-

Currently, double-glazed windows are widely used as windows of buildings. As shown in the exploded perspective view of FIG. 1, this double-layer glass has two glass plates 101 and a pair of glass plates 101 between the two glass plates 101 so as to form a space having a constant gap between the two glass plates 101 At least one gap member 102 interposed therebetween, and a key 103 connecting the two adjacent gap members 102 to each other.

Recently, in order to increase the effect of insulation and sound insulation of the double-layer glass, the space between the two glass plates is filled with a gas such as argon, helium, krypton or SF6. As disclosed in Patent Document 1, the fill gas is injected into the cavity of the multilayer glass through the ejector by combining a key and a separately injected ejector in a through hole provided in the key.

However, since the conventional art disclosed in Patent Document 1 requires a separate gas injection ejector in addition to a key, the number of component parts is large, which is not only complicated, but also raises the manufacturing cost.

In addition, in the conventional technique, a coupling hole for coupling the ejector to the key is pierced, and a separate ejector is coupled to the coupling hole when gas is injected. When the gas injection is completed, the ejector is separated from the coupling hole of the key And then the sealing member is sealed with the sealing member. According to this structure, the gas is leaked through the gap between the coupling hole and the ejector, so that the gas filling efficiency is low. After the ejector is removed, the filled gas is leaked through the coupling hole while sealing the coupling hole with the sealing member And the like.

Disclosure of the Invention The present invention is conceived to solve the disadvantages or problems of the conventional gas injecting apparatus described above, and it is an object of the present invention to provide a gas injecting apparatus capable of completely shutting off the leakage of gas already filled in the gas injection without using a complicated structure- It is an object of the present invention to provide a key for gas injection of a double-layer glass which is simple in structure.

According to an aspect of the present invention, there is provided a key for connecting two gap members adjacent to each other in a multi-

Wherein the key includes a coupling member for coupling to each tip of two gap members connected to each other, and a connection portion disposed between the coupling members, wherein the coupling portion is formed with a gas injection, sealing the gas injection to the gas injection, And a sealing member made of an elastic rubber material is provided so as to pass the injection needle tightly.

The key may be formed of a straight key to be connected to a part of the linear clearance material disposed on the four sides of the multilayer glass, and may be disposed at at least one corner or at one or more edges of the four sides of the multilayer glass, And a curved key extending at an angle at both ends of the connection portion.

Wherein the sealing member includes a base portion and a plug portion which is fitted and sealed in an inlet portion of the gas injection, the connecting portion includes a sealing member mounting groove for receiving the sealing member, and on the upper side of the sealing member mounting groove, A lid portion for covering the base portion of the sealing member, and a cover plate having a hole through which the plug portion of the sealing member is inserted and which exposes the outer surface of the plug portion to the outside.

The sealing member is preferably formed of butyl rubber. The present invention is not limited to the case where the sealing member is made of butyl rubber, and it is also possible to form the sealing member with other kinds of rubber materials.

An o-ring for blocking the gas leakage is interposed between the gap material and the engagement surface of the engagement hole of the key coupled to the gap material, thereby preventing the gas from leaking between the gap material and the engagement hole.

The key engagement portion has two or more contact protrusions which elastically deform when the key is inserted into the inner hole of the gap member and closely contact the inner wall of the gap member while the contact protrusions are inclined at a predetermined angle .

According to the present invention configured as described above, it is possible to completely block leakage of gas already filled up when gas is injected, without using a complicated structure such as an ejector, and to simplify the structure and reduce the cost.
