Pipe fixing system and pipe fastening device
A pipe fixing system comprises a cylindrical body having a tapering part whose diameter is smaller as it goes towards the top of the body; an entry provided in the body and having a bolt hole and a projection; a fixing chip provided in the tapering part, having, in the center, a bolt hole extending from the top to the bottom of the chip and having teeth on the surface contacting a pipe; and a bolt passing through the bolt hole of the entry and that of the fixing chip. A a spring recess and a bolt end are provided on lower part of the bolt and a spring is provided in the spring recess to prevent unintentional movement of the bolt.
1. A pipe fixing system, comprising:
a cylindrical body having a tapering part whose diameter is smaller as it goes towards the top of the body;
an entry provided in the body and having a bolt hole and a projection;
a fixing chip provided in the tapering part, having, in the center, a bolt hole extending from the top to the bottom of the chip and having teeth on an inner surface contacting a pipe; and
a bolt passing through the bolt hole of the entry and that of the fixing chip,
wherein a spring recess and a bolt end are provided on the lower part of the bolt and a spring is provided in the spring recess to prevent unintentional movement of the bolt.
2. The system as claimed in claim 1 , the body comprises:
an entrance stop above the tapering part for fixing the entry to prevent the entry from being released from the body;
an upper insertion groove extending from the entrance stop and in which the entry is inserted;
a guide surface extending from the upper insertion groove;
a lower insertion groove in which a snap ring is provided below the tapering part;
a recess on which a packing rests;
a guide wall and a stop in which the end of the pipe is inserted and rests.
3. The system as claimed in claim 2 , characterized in that the packing is made of metal.
4. The system as claimed in claim 2 , characterized in that the packing is an o-ring made of rubber or synthetic resin.
5. The system as claimed in claim 1 , characterized in that a spring washer is inserted between the upper surface of the entry and the head of the bolt.
6. The system as claimed in claim 1 , characterized in that the bottom of the body is provided with a horizontal attaching plate for fixing the body.
7. The system as claimed in claim 1 , characterized in that the fixing chip is provided with a projection on the side opposite the teeth.
8. The system as claimed in claim 1 , characterized in that the interior of the body is provided with a vertical recess corresponding to a projection of the fixing chip to allow the fixing chip to move up and down.
9. The system as claimed in claim 1 , characterized in that two or three fixing chips are provided in the body.
10. The system as claimed in claim 9 , characterized in that the body is symmetrical so as to permit a pipe to be inserted and fixed in each end of the body.
