Non-welding solar collector tube connecting structure

Abstract

A non-welding solar collector tube connecting structure includes a collector tube having a tube wall, a containing space, a screw hole and a penetrating hole. The penetrating hole is interconnected to the containing space, and the connecting sleeve includes a tube pillar having a through hole, a plurality of screw threads formed on an external periphery of the tube pillar. A ring plate is installed at an end of the row tube, and the row tube is passed through the tube pillar, and a front end of the tube pillar is abutted against the ring plate, and the row tube is coupled to a side of the collector tube through tube pillar, and the ring plate is compressed by the tube pillar and abutted against the exterior of the penetrating hole.

What is claimed is: 
     
         1 . A non-welding solar collector tube connecting structure, comprising:
 a collector tube, including a tube wall, a containing space formed by surrounding the tube wall, a screw hole formed on a side of the collector tube and not penetrated through the tube wall, and a penetrating hole disposed in the screw hole and interconnected with the containing space;   a connecting sleeve, including a tube pillar having a through hole, and a plurality of screw threads formed on an external periphery of the tube pillar and screwed into the screw hole; and   a row tube, being a hollow tube, and having a ring plate installed at an end of the row tube and abutted against an outer side of the penetrating hole, and the row tube passing through the tube pillar, and a front end of the tube pillar abutting against the ring plate;   wherein, the row tube is screwed into the screw hole through the tube pillar and coupled to a side of the collector tube, and the ring plate is compressed by the tube pillar and abutted against the exterior of the penetrating hole.   
     
     
         2 . The non-welding solar collector tube connecting structure of  claim 1 , wherein the tube wall has a retaining wall formed and protruded inwardly from the periphery of the penetrating hole. 
     
     
         3 . The non-welding solar collector tube connecting structure of  claim 2 , further comprising a seal plate clamped between the retaining wall and the ring plate. 
     
     
         4 . The non-welding solar collector tube connecting structure of  claim 1 , wherein the connecting sleeve further comprises a knob coupled to the tube pillar, and the through hole is penetrated through the tube pillar and the knob. 
     
     
         5 . The non-welding solar collector tube connecting structure of  claim 1 , wherein the through hole has a diameter greater than the diameter of the row tube. 
     
     
         6 . The non-welding solar collector tube connecting structure of  claim 1 , wherein the solar collector further comprises two collector tubes, a plurality of row tubes installed between the two collector tubes, a connecting sleeve passed through both ends of each row tube separately, and a ring plate installed at both ends of the row tube separately. 
     
     
         7 . The non-welding solar collector tube connecting structure of  claim 6 , wherein each of the row tubes is embedded onto a solar panel. 
     
     
         8 . The non-welding solar collector tube connecting structure of  claim 6 , wherein each of the row tubes is embedded onto the same solar panel. 
     
     
         9 . The non-welding solar collector tube connecting structure of  claim 1 , wherein the ring plate is extended outwardly from an edge of the row tube and integrally formed with the row tube. 
     
     
         10 . The non-welding solar collector tube connecting structure of  claim 1 , further comprising a sealing ring sheathed on an edge of the row tube and installed to the ring plate. 
     
     
         11 . The non-welding solar collector tube connecting structure of  claim 10 , wherein the sealing ring and the row tube are installed separately, and the sealing ring is connected onto the row tube by a welding method.
