The present invention relates to a pipe fastening device for joining pipes and pipes, and more particularly to a pipe fastening device for fastening two orthogonal pipes.

In general, the use of a lot of pipes in daily necessities arises the need to use pipes and pipes. In particular, if the fastening of the pipe is bad there is a risk of damage to the product using the pipe during use or injury to the user. Therefore, it is necessary to tighten the pipe strongly.

In the past, the welding was mainly performed when the pipe was fastened with the pipe. However, such a fastening means is not beautiful in appearance and has a problem such as not having a strong bonding force. In addition, the use of a combination of pipes causes a lot of inconvenience.

Accordingly, an object of the present invention is to provide a pipe fastening device that can easily and easily combine two pipes orthogonal to each other.

The object of the present invention is a pipe fastening device having a fastening screw for fastening at least two pipes, the diameter of the openings on both sides of the first pipe is formed to pass through differently, so that the fastening screw is completely immersed A female screw inserted into one end of the second pipe which is orthogonally coupled to the first pipe and positioned to coincide with the screw fastening hole, and having a fastening screw penetrating therein through the screw fastening hole. Achieved by a pipe fastener having a ball and comprising a cylindrical fastener with a smaller diameter than the second pipe.

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

1 is an exploded perspective view showing each component of the pipe fastening device according to the present invention. As shown, the pipe fastening device includes a first pipe 10, a second pipe 20, a fastening screw 30, and a cylindrical fastener 40. The first pipe 10 has a first fastening hole 11 formed at a portion to which the second pipe 20 perpendicular to each other is fastened, and has a second fastening hole 12 having a diameter larger than this in a straight line. Doing. At this time, the first fastening hole 11 and the second fastening hole 12 of the first pipe 10 into which the fastening screw 30 is inserted are called screw fastening holes. In addition, the fastening screw 30 is composed of a large diameter head portion 31 and a screw portion 32 having a screw formed in a smaller diameter, the wrench portion 31 is formed in the head portion 31. .

One end of the second pipe 20 coupled to the first pipe 10 is a semispherical first recessed surface 21 to be coupled along the outer surface curve of the first pipe 10. In addition, the cylindrical fastener 40 smaller than the outer diameter of the second pipe 20 inserted into the second pipe 20 has a female thread 41 formed therein, where the screw of the fastening screw 30 is located. The part 32 is fastened. An annular groove 42 is formed on the outer surface of the cylindrical fastener 40 in contact with the inner surface of the second pipe 20. Therefore, when the cylindrical pipe fastener 40 is inserted into the second pipe 20, when a pressure is applied to the outer surface of the second pipe 20 in which the annular recess 42 of the cylindrical fastener 40 is positioned, the second pipe ( The annular projection 25 projecting from 20 is immersed in the annular groove 42 and is firmly fixed. In addition, the cylindrical fastener 40 may be inserted into the second pipe 20 and fixed by welding or the like. In addition, a semi-circular second concave indentation surface 43 is also formed on one side of the cylindrical fastener 40 in contact with the first pipe 10 to be in close contact with the first pipe 10.

2 is a cross-sectional view of the assembly of the pipe fastening device according to the present invention. As shown in the drawing, a cylindrical fastener 40 having an outer diameter smaller than the inner diameter of the second pipe 20 is inserted into the second pipe 20 so that the annular recess 42 of the cylindrical fastener 40 is located. 2 Apply pressure to the outer surface of the pipe 20 to fix it. Then, the annular projection 25 protruding from the inner surface of the second pipe 20 is in close contact with the annular recess 42 to be firmly fixed. Then, the female helix forming portion of the second pipe 20 fixing the cylindrical fastener 40 coincides with the insertion holes of the first pipe, and then is fastened through the second hole 12 of the first pipe 10. Insert the screw 30 and insert the wrench insertion hole 33 wrench, the user rotates the wrench. Then, as the fastening screw 30 rotates, the screw portion 32 of the fastening screw is fixed to the female thread 41 of the cylindrical fastener 40 so that the first pipe 10 and the second pipe 20 are firmly secured. Is fastened. Of course, you may use another tool by forming the groove | channel in which the tool other than a wrench is inserted in the head part 31 of the fastening screw 30. FIG.

As described above, the pipe fastening device according to the present invention uses a fastening screw and a fastener when joining two orthogonal pipes, and thus, the appearance is clean, the bonding strength is excellent, and there is an advantage in convenience of use.
