Connection member of movable type camp having good detachability

Abstract

The present invention discloses, a connection member of a movable type camp with a good detachability comprising: a main pipe and an auxiliary pipe having a penetration hole at a predetermined portion of its external circumference surface, respectively; an elastic member having a “⊃” shape attached to the inside of the auxiliary pipe so that a constant elastic force is generated toward the inside circumference portion from the center of the auxiliary pipe; and a connection protrusion formed at the top surface of the upper end portion of the elastic member, which is inserted to the penetration holes of the main pipe and the auxiliary pipe and exposed to the outside, whereby the assemble and disassemble processes of the framework are performed easily.

1 . In a framework connection structure of a camp in which the framework is constructed by a main pipe having a predetermined diameter and openings formed its both ends, respectively and an auxiliary pipe inserted to the main pipe for forming the framework, a connection member of a movable type camp with a good detachability comprising: 
 the main pipe and the auxiliary pipe having a penetration hole at a predetermined portion of its external circumference surface, respectively;    an elastic member having a “⊃” shape attached to the inside of the auxiliary pipe so that a constant elastic force is generated toward the inside circumference portion from the center of the auxiliary pipe; and    a connection protrusion formed at the top surface of the upper end portion of the elastic member, which is inserted to the penetration holes of the main pipe and the auxiliary pipe and exposed to the outside, whereby the assemble and disassemble processes of the framework are performed easily.    
   
   
       2 . The connection member of a movable type camp with a good detachability of  claim 1 , wherein the connection protrusion has a front surface inclined portion formed with a predetermined angle α by a grinding process at its front surface portion, so that when connecting the main pipe and the auxiliary pipe, the opening of the main pipe can press the connection protrusion.  
   
   
       3 . The connection member of a movable type camp with a good detachability of  claim 1 , wherein the connection protrusion has a side surface inclined portion formed with a predetermined angle β by a grinding process at its side surface portion, so that when disassembling, when the auxiliary pipe is rotated toward a direction, the penetration hole of the main pipe can press the side surface inclined portion of the connection protrusion.
