Pressure tank having a connector that may be assembled rapidly and tightly

Abstract

A pressure tank includes a tank body, and a connector. The tank body is formed with a through hole. The connector is integrally formed by a stainless steel material, and includes a threaded section, a soldering section, and a press section. The press section of the connector is passed through the through hole of tank body, and is riveted and secured on an inner side of the tank body. The press section of the connector includes a support portion, and a rivet press portion and having a wall thickness smaller than that of the support portion.

What is claimed is:  
     
         1 . A pressure tank having a connector that may be assembled rapidly and tightly, comprising: a tank body, and a connector, wherein: 
 the tank body is formed with a through hole;    the connector is integrally formed by a stainless steel material, and includes a threaded section, a soldering section, and a press section;    the threaded section of the connector is connected to a water pipe;    the soldering section of the connector is mounted on a lower portion of the threaded section of the connector, and has a cylindrical shape, so that the soldering section of the connector may be soldered on the tank body rapidly; and    the press section of the connector is mounted on a lower portion of the soldering section of the connector, and is passed through the through hole of tank body, the press section of the connector is riveted and secured on an inner side of the tank body, the press section of the connector includes a support portion mounted on the lower portion of the soldering section of the connector, and a rivet press portion mounted on a lower portion of the support portion.    
     
     
         2 . The pressure tank having a connector that may be assembled rapidly and tightly in accordance with  claim 1 , wherein the rivet press portion of the press section of the connector has a wall thickness smaller than that of the support portion of the press section of the connector, so that the support portion of the press section of the connector may function as a support, and the rivet press portion of the press section of the connector may be deformed and pressed easily during a rivet press process.  
     
     
         3 . The pressure tank having a connector that may be assembled rapidly and tightly in accordance with  claim 1 , wherein the connector further includes a leakproof ring mounted on the support portion of the press section of the connector and received in an inner side of the tank body, and the leakproof ring is pressed by the rivet press portion of the press section of the connector.  
     
     
         4 . The pressure tank having a connector that may be assembled rapidly and tightly in accordance with  claim 1 , wherein the support portion and the rivet press portion of the press section of the connector has a connection located at a central position of the leakproof ring.  
     
     
         5 . The pressure tank having a connector that may be assembled rapidly and tightly in accordance with  claim 1 , wherein the tank body includes an upper barrel, an inner barrel, a washer, an inflation diaphragm, a press ring, and a lower barrel, wherein: 
 the upper barrel is formed with a through hole for passage of the connector;    the inner barrel is mounted in an inner side of the upper barrel, and is formed with a through hole aligning with the through hole of the upper barrel, the through hole of the inner barrel has an inner side provided with a lug which is formed with a recess for receiving the leakproof ring;    the washer is mounted between the upper barrel and the inner barrel;    the inflation diaphragm is mounted on an inner side of the inner barrel, and a water storage space is formed between the inflation diaphragm and the inner barrel;    the press ring is mounted on a bottom edge of the inflation diaphragm, for securing the bottom edge of the inflation diaphragm on the inner barrel; and    the lower barrel has a top edge secured with a bottom edge of the upper barrel, so that the lower barrel may be combined with the upper barrel to form a closed tank, an air inflation space is formed between the inflation diaphragm and the lower barrel.    
     
     
         6 . The pressure tank having a connector that may be assembled rapidly and tightly in accordance with  claim 5 , wherein the lower barrel has a bottom edge provided with an air inflation nozzle for filling a gas.  
     
     
         7 . The pressure tank having a connector that may be assembled rapidly and tightly in accordance with  claim 5 , wherein the press section of the connector is passed through the through hole of the upper barrel, the washer, and the through hole of the inner barrel, and is pressed in a riveting manner, thereby securing the inner barrel and the washer on the upper barrel.
