Description

Sealing means for airtightness and pipe connecting device having same {PACKING MEANS FOR SEALING, AND CONNECTOR FOR A PIPE WITH THE SAME}

The present invention relates to an airtight packing means for use in cylindrical pipes such as water and sewage pipes, storm water pipes, electric wire storage pipes, and gas pipes, and a pipe connection device having the same.

As is known in the art of connecting two or more pipes (pipes), that is, socket type, heat shrinkage type, fusion type, etc. are well known and commonly used.

However, as described in the applicant's Korean Patent Registration No. 0562782, the socket type, the heat shrink type, and the fusion type have many disadvantages in use, and in order to improve these disadvantages, the applicant is easy to connect and connect the pipes in the registered patent. In addition, the company introduced a pipe connection device that is robust, improves watertightness, and requires less labor and cost.

The pipe connecting device introduced in the applicant's patent No. 0562782 will be briefly described with reference to FIGS. 1 and 2.

The pipe connecting device of the above patent is a pair of fixing members 30 and 40 that are fitted to each end of the corresponding pipes and fixed to one of these fixing members, the other side of the fixing member is coupled to the corresponding Consists of a fastening member 50 for fastening.

Of these fixing members, the first fixing member 40 has a protrusion 42 formed at one end thereof, and the second fixing member 30 has a concave portion 33 formed at one end thereof. When the connection between the second fixing member 40 and the second member 30, the recess 33 is shown in the connection form is inserted into the contact portion 42 close.

In addition, the second fixing member 30 is formed with a first threaded portion 31 on the outer circumferential surface, and the fastening member 50 has a second threaded portion 51 formed on the inner circumferential surface of these screw portions 31 and 51. The coupling between the first fixing member 40 and the second fixing member 30 is made.
