Description

A coupling device for a gas suppling tube

The present invention relates to a hose connector for gas supply for connecting the hose more stably and beautifully to the gas inlet pipe fixed to the combustion mechanism of the stove.

In general, as a gas stove used in a home or a restaurant, a gas supply hose for connecting gas from a gas pipe or a gas cylinder is connected and installed. Referring to FIG. 1, the connection state of a conventional hose is as follows.

As shown in FIG. 1, the gas supply hose 4 is directly pushed by a predetermined depth with respect to the connection tip 3 of the gas inlet pipe 2 fixedly installed in the combustion mechanism of the gas stove 1, and then the connection is performed. The outer peripheral surface of the hose 4 inserted in the tip 3 was tightened and fixed with the ring-shaped tightening band 5.

Therefore, according to the above connection structure, since the hose 4 is simply fixed to the gas inlet pipe 2 by the tightening band 5, there is an advantage that the connection assembly of the hose 4 is very simple and convenient. Since the structure of fixing the hose 4 directly to the connection tip 3 of the gas inlet pipe 2 is above all the connection tightening appearance of the hose 4 is exposed to the outside as it is not beautiful and unstable problem.

In addition, since the hose 4 is directly flowed together with the connection tip 3 of the gas inlet pipe 2, when the gas stove 1 is frequently moved and used, stress due to deformation, such as bending or bending of the hose, is tightened. As (5) is concentrated to the tightening part, the hose of the tightening part can not be ruled out of the possibility of breakage or damage, and when used, meat is cooked by the tightening force weakening of the tightening band (5) or the tightening part of the corresponding hose (4). When the oil generated during the flow flows there is a problem that the hose 4 is easily separated even by a small external force.

Therefore, the present invention has been devised to solve such problems in the related art, and an object of the present invention is to indirectly connect and install the gas supply hose at a predetermined distance with respect to the connection tip of the gas inlet pipe, and at the same time, tighten the appearance of the hose. It is to provide a hose supply device for gas supply that is beautiful and stable.

Technical features of the gas supply hose connecting device for achieving the above object, the hose connection for connecting the gas supply hose indirectly connected to each other with respect to the connection tip of the gas inlet pipe detachable to the combustion mechanism of the gas stove In configuring the device; One end of the hose connector is connected to the gas supply hose with a fastening band by pressing the fastening band, and the other end of the cover tube is required to be inserted so that the protruding frame of the packing tube elastically coupled to the inner peripheral surface of the packing tube Is tightly supported by an elastic ring body, and the connection tip 12 of the gas inlet pipe fitted into the inner circumferential surface of the packing tube is pressed and fixed with a tightening band inserted into the outer circumferential surface of the packing tube so that the protruding piece is positioned in the cutting groove of the cover tube. The end of the cover tube is covered with a cap and fixed.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

1 is an exploded perspective view of a hose connecting device for gas supply according to the present invention, Figure 2 is an assembled side cross-sectional view thereof, the hose connecting device of the present invention is a gas inlet pipe detachable to the combustion mechanism of the gas stove not shown ( It is for indirectly connecting the gas supply hoses 20 to each other with respect to the connection tip 12 of 10).

As shown in FIGS. 1 and 2, the gas supply hose 20 is press-fixed and fixed by the tightening band 30 to the connection tip 112 formed at one side of the hose connector 100 and integrally formed at the other side. The cover pipe body 114 is provided with a packing pipe body 120 for sealing the connection tip 12 of the gas inlet pipe 10, respectively.

The packing tube 120 inserted into the cover tube body 114 is elastically coupled to the catching member 116 that is formed to correspond to the inner circumferential surface of the cover tube body 114, and the inner circumferential surface of the protrusion frame 122. By inserting the elastic ring body 130 to be tightly supported mutually to prevent any separation.

Here, the elastic ring body 130 is to fully support the protrusion frame 122 of the packing pipe body 120 in the locking demands 118 of the cover pipe body 114, and is to be made in the form of a pipe to forcibly close the pipe. Preferably, it is also possible to use a washer type that can be self-tank operation.

And the tightening band 140 is installed between the cover tube 114 and the packing tube 130, the protruding piece 142 of the tightening band 140 is the cutting groove 118 of the cover tube 114 to

It is fitted tightly.

On the other hand, the cap 150 for covering the end of the cover tube 114 is formed with a hole 152 that is fitted to the connection tip 12 of the gas inlet pipe 10.

Therefore, the present invention configured as described above connects and fixes the gas supply hose 20 to the tightening band 30 with the connection tip 112 formed as one side of the hose connector 100 as shown in FIGS. 3 and 4, Protruding piece of the tightening band 140 inserted into the cover pipe body 114 is inserted into the packing pipe body 120, and then pushes the connection tip 12 of the gas inlet pipe 10 into the outer circumferential surface of the packing pipe body 120 ( The connection tip 12 of the gas inlet pipe 10 is assembled by forcibly squeezing the 142, and the cap 150 is finally covered by the end of the cover pipe body 114 to close the connection of the hose. This is beautiful.

And the connecting tip 12 of the gas inlet tube 10 as shown in Figure 4 is securely sealed by the packing tube body 120 which is pressed together by forcibly tightening the protruding piece 142 of the tightening band 140. will be.

Meanwhile, as shown in FIG. 5, the packing tube 120 is tightly sealed by the elastic ring body 130 in the state where the protruding frame 122 is fitted into the locking demand 118 of the cover tube 114. Gas supplied through) is prevented from flowing out of the gas between the cover tube body 114 and the packing tube body 120, and also the arbitrary separation of the packing tube body 120 is prevented.

As described above, according to the present invention, the hose is more stable and beautiful by separately indirectly installing the gas supply hose and the connection tip of the gas inlet pipe instead of installing the gas hose directly connected to the connection tip of the gas inlet pipe. As the hose flows indirectly through the hose connector instead of directly flowing when the connection tip of the gas inlet pipe flows, the gas hose receives less tightening stress due to the flow, thereby improving stability. It is to have an advantage.

Although the present invention has been described with reference to the accompanying drawings, many modifications and changes may be made without departing from the scope of the following claims.
