Abstract

end. The technical field to which the invention described in the claims belongs.

The present invention relates to a fixed clamp of a city gas pipe to fix the city gas pipe to a wall surface, and especially when the pipe is fixed with a clamp, the metal material of the pipe and the clamp are different, and the electrical characteristics of the pipe This prevents corrosion and simplifies clamping.

I. The technical problem the invention is trying to solve.

Conventionally, in order to fix the city gas pipe on the wall, place the pipe on the upper part of the bracket, insert the U-shaped clamp into the hole of the bracket at the upper part of the pipe, and then expose the tip of the clamp to the lower end of the bracket. The pipe was fixed to the bracket by tightening the nut on the formed thread.

In addition, since the metal material of the pipe and the clamp or bracket is different from each other, the insulation tape is wound at the position where the clamp of the pipe is inserted in order to prevent corrosion of the pipe due to the difference in electrical characteristics.

Therefore, there is a problem that the working efficiency for nut coupling to both sides of the taping operation and the clamp is reduced.

All. The gist of the solution of the invention.

One end of the U-shaped clamp forms a screw thread to tighten the nut, and the other end forms a bent portion to hook the bent portion to the bracket's locking hole and tighten the nut only on one side so that the pipe can be easily and firmly assembled. In order to prevent corrosion of the abutment between the pipe and the U-shaped clamp, a protective cap made of synthetic resin is used to prevent corrosion and at the same time, one side of the protective cap is inclined incline to be easily inserted regardless of the diameter of the pipe. To ensure that

Description

Clamp which fixes the pipe of urban gas}

The present invention relates to a city gas pipe fixing clamp for easily fixing a city gas pipe to a wall surface. In particular, the city gas pipe can be easily prevented from being corroded by characteristics due to differences in metal materials and can be easily installed. It relates to a gas pipe fixing clamp.

Conventionally, in order to install and fix the city gas pipe 108, the U-shaped clamp 102 having the threads 104 and 104a formed on both sides of the bracket 100 is fixed by the nuts 110 and 110a. Perforate the locking holes 106 and 106a up and down so that the city gas pipe is inserted into the U-shaped clamp 102, and the nuts 110 on both sides of the U-shaped clamp 102 at the rear of the bracket 100. ), 110a by tightening the pipe and the U-shaped clamp is to be pressed.

At this time, while holding the pipe 108 with one hand, the nut 110, 110a should be tightened and fixed in a balanced manner, but it is difficult to balance the pipe 108, which lowers the efficiency of the work.

In addition, the pipe 108 is a corrosion occurs when a long time flows due to the characteristics of the metal material in contact with the U-shaped fastener 102, which is a safety problem due to the outflow of city gas.

Therefore, in order to prevent corrosion, the tape 108 is wrapped with the tape 112 at the portion where the U-shaped clamp 102 is in contact with the pipe 108, which is also a tape 112 when the U-shaped clamp 102 is firmly tightened the connector 108. If the hedge or loosening, the tape 112 is lifted, which may not function properly and the pipe 108 may not be firmly fixed.

One side of the U-shaped clamp is formed on the bracket with the hole drilled up and down so that the nut can be tightened, and the other end is formed with a bent in the L-shape to hang the bent part through the bracket's hook hole and the pipe to the U-shaped clamp. Even if the nut is tightened on only one side after inserting, the bent part is pressurized to the bracket and the pipe is easily assembled.

Another object of the present invention is to prevent corrosion by using a protective cap made of synthetic resin to prevent corrosion of the abutment portion between the pipe and the U-shaped clamp, and at the same time, incline one side to be inclined to simply cut it where necessary regardless of the diameter of the connector. Is to make it plug in.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.

As shown in Figs. 1 to 5, the structure of the present invention is a fixed clamp of a known city gas pipe, wherein one end of the U-shaped clamp 3 forms a thread 4 and the other end is bent. Form the part 5 to hook the bent part 5 to the locking hole 2a in the bracket 1, and to fit the pipe 9 into the U-shaped clamp 3, and then at the rear of the bracket, the U-shaped clamp 3 When the nut 6 is tightened to one side thread 4, the bent portion 5 is pressed against the bracket 1 to fix the pipe 9. The pipe 9, which is in contact with the U-shaped clamp 3, has an inclined surface 8. ), (8a) is configured to combine the protective cap (7) incision.

At this time, since the bent portion 5 is also pressed at the same time when tightening the nut 6, the U-shaped clamp 3 maintains a parallel state, so that the pipe 9 is not crookedly fixed and there is no easy operation.

In addition, the city gas pipe 9 is connected by a plurality of fixed clamps to prevent the pipe 9 from being skewed between the fixed clamps 3 in advance.

In addition, the protective cap (7) coupled to the connector (9) to prevent corrosion is to cut one side alternately so that the inclined surface (8, 8a) is formed, as shown in Figure 4 pipe (9) of small diameter When used in one side of the inclined surface (8a) and the other inclined surface (8) is to be combined to overlap.

In addition, the protective cap (7) was made of a synthetic resin material to be used semi-permanently, and easily inserted into the pipe (9) of different diameters to facilitate the operation.

As described above, the present invention uses only one side of the U-shaped fastener to fix the nut, thereby reducing costs and increasing work efficiency. The protective cap made of synthetic resin is semi-permanent and can be conveniently inserted into any part of the pipe. will be.
