Description

[0001] MARKING APPARATUS FOR REFRIGERANTS PIPE [0002]

The present invention relates to a marking apparatus for an air conditioner piping for marking a minimum insertion depth on the outer circumferential surface of a refrigerant pipe before inserting a refrigerant pipe of an air conditioner or the like into a fitting opening for a one-touch type refrigerant pipe.

Unless otherwise indicated herein, the contents of this identification are not prior art to the claims of this application and are not to be construed as being prior art to the extent that they are included in this identification.

Generally, a refrigerant pipe corresponds to a conduit through which a refrigerant flows in a refrigerator such as an air conditioner or a refrigerator. A refrigerant pipe of copper or copper alloy material having high thermal conductivity and excellent rigidity and ductility is mainly used. Is often used.

Conventionally, in order to connect the refrigerant pipe, a method of welding and fixing the end of the pipe and the end of the pipe in surface contact is used. However, there was.

In order to solve such a problem, Japanese Patent Application Laid-Open No. 10-2010-0096974 (published on Sep. 2, 2010) discloses a refrigerant pipe connecting apparatus for a refrigerant pipe connecting apparatus, which comprises a socket for receiving an end of a pipe so as to be caught by a step, A sealing member which is connected to the pipe and tightly closes the outer circumferential surface of the pipe and the inner circumferential surface of the socket by a deformation which is compressed and expanded by the pressing force of the fastening member and is fastened to the fastening portion of the socket so as to press- A piping connection device for an air conditioner is disclosed, which comprises a fastening member.

Also, Korean Patent Registration No. 10-1523185 (published on May 26, 2015) discloses a refrigerant pipe having a flared portion with one end expanded and a valve or nipple having a pipe connection portion formed with a first tapered surface corresponding to the inclination of the flare portion, The refrigerant pipe connecting apparatus according to claim 1, wherein the refrigerant pipe connecting member is formed with a hollow through the inside thereof in the longitudinal direction, the refrigerant pipe is passed through the one end thereof, the thread is formed on the inner circumferential surface of the other end, And a second tapered surface corresponding to the first tapered surface is formed at a front end of the connecting nut and is movable back and forth in the hollow of the connecting nut in a state where the flared portion is interposed between the first tapered surface and the second tapered surface Wherein the flared portion is in surface contact between the first tapered surface and the second tapered surface, A proper torque notifying the user of the rotation stopping point of the connecting nut so that the other end of the connecting nut can be screwed to the predetermined torque, Disclosed is a refrigerant piping connection device which is easy to install, including a means.

In the case of the above-described conventional cold-storage piping connection apparatus, since the refrigerant piping is hermetically coupled only when the fastening member or the connection nut is rotated, the connection of the refrigerant piping is still not easy and time-consuming .

In order to solve this problem, there has been developed a one-touch type fitting connection fitting (product name: SB1) for a one-touch type refrigerant pipe which is welded to a refrigerant pipe connection portion of an air conditioner by Esen Tech Co., Ltd. and which can be fastened by a one-

The above-mentioned fitting connection port for a one-touch type refrigerant pipe has a structure in which a watertightness is maintained while an inner packing ring is compressed between an inner circumferential surface of a fitting connection port and an outer circumferential surface of a cold-storage pipe. In the case of 1/4 inch or 3/8 inch diameter refrigerant piping, it should be inserted into the fitting connection for the above-mentioned one-touch refrigerant piping by a length of at least 21.0 mm, for example, or 1/2 inch or 5/8 inch diameter In the case of a refrigerant pipe of a length of at least 24.0 mm into the above-mentioned one-touch type refrigerant pipe fittings.

If the refrigerant pipe is not properly inserted into the fitting opening for the one-touch type refrigerant pipe, the watertightness of the packing ring can not be maintained properly, and the refrigerant gas may leak.

The operator who inserts and connects the refrigerant pipe by using the above-mentioned one-touch type refrigerant pipe fitting connector carries a ruler and a marker pen, marks the minimum insertion depth according to the diameter of the refrigerant pipe directly, inserts the refrigerant pipe , This operation is not only cumbersome but also increases the working time.

The marking protrusion 20 scrapes the outer circumferential surface of the refrigerant pipe 10 during rotation of the refrigerant pipe 3 inserted into the insertion groove 11 of the marker body 10 and displays an annular indication line 5, .

The marking protrusions 20 may protrude from the front end of the insertion groove 11 of the marker body 10, but a plurality of the marking protrusions 20 are preferably protruded one by one at predetermined angular intervals.

FIG. 3 is a use state diagram of a marking apparatus for a refrigerant pipe according to an embodiment of the present invention.

First, the construction and operating relationship of the one-touch type refrigerant pipe fitting connection 7 applied to the connection of the refrigerant pipe 3 are described in detail, for example, as fitting connection fittings for a one-touch type refrigerant pipe (product name SB1) developed by Essen- As is well known in the technical field, detailed description will be omitted here for the sake of simplification of the description.

The operator inserts the refrigerant pipe 3 used for the air conditioner into the fitting opening 7 for the one-touch type refrigerant pipe. First, the refrigerant pipe 3 is inserted into the fitting opening 7 for the refrigerant pipe by using the refrigerant pipe marking apparatus according to an embodiment of the present invention. An indicating line 5 indicating the minimum insertion depth is marked on the outer circumferential surface of the pipe 3.

At this time, if the worker inserts the refrigerant pipe 3 into the insertion groove 11 of the marker body 10 corresponding to the diameter and rotates it at a certain angle, the outer circumferential surface of the refrigerant pipe 3 becomes the marking projection 20, The indication line 5 indicating the minimum insertion depth is quickly marked.

Then, the operator inserts the refrigerant pipe 3 into the fitting opening 7 for the one-touch-type refrigerant pipe so that the indicating line 5 is not visible to the naked eye. The connection operation of the pipe 3 can be performed quickly and reliably without leakage of the refrigerant gas.

4 is a cross-sectional view of a modified embodiment of a marking apparatus for a refrigerant pipe according to an embodiment of the present invention.

The marking apparatus for a refrigerant pipe according to an embodiment of the present invention includes a plurality of marker bodies 10 in which marking protrusions 20 are formed in an insertion groove 11 as shown in FIG. .

In this case, the marking apparatus for a refrigerant pipe according to an embodiment of the present invention has a structure in which two marker bodies 10, each having one insertion groove 11 of different diameter, are integrally arranged in parallel with each other .

As long as the operator carries the above-mentioned marking device for the refrigerant piping, the refrigerant piping 3 of four different diameters, in particular 1/4 inch, 3/8 inch, 1/2 inch and 5/8 inch diameter, The indicating line 5 indicating the minimum insertion depth can be quickly and easily marked.

5 is a cross-sectional view of another modified embodiment of a marking apparatus for a refrigerant pipe according to an embodiment of the disclosure.
