Water outlet coupling head

Abstract

A water outlet coupling head includes a hollow coupling head body, a rotary bolt running through the interior of the coupling head body, a coupling member and an elastic thrust member. The coupling head body is coupled with a spout of a water outlet head. The rotary bolt has a first end perimeter which has a detent member extending radially outwards and a second end perimeter which has a diameter smaller than the first end perimeter to run through the thrust member and fasten to the coupling member. The thrust member has one end pressing a bucking ring located in the coupling head body and another end ramming a pressing portion of the rotary bolt. Thereby the coupling member can be fastened to the water outlet head and positioned in a selected direction.

1 . A water outlet coupling head, comprising: 
 a hollow coupling head body which is coupled with a spout of a water outlet head;    a rotary bolt running through the interior of the coupling head body and having a first end perimeter which has a detent member extending radially outwards and a second end perimeter which has a diameter smaller than the first end perimeter to form a pressing portion on a juncture therebetween and a second screw thread formed thereon;    a coupling member fastened to the second screw thread; and    an elastic thrust member coupling on the rotary bolt and having one end pressing a bucking ring located in the coupling head body and another end ramming the pressing portion of the rotary bolt.    
   
   
       2 . The water outlet coupling head of  claim 1 , wherein the first end perimeter of the rotary bolt where the detent member is located is close to the water outlet head, the coupling head body having a harness notch corresponding to the detent member to limit the rotational angular range of the rotary bolt.  
   
   
       3 . The water outlet coupling head of  claim 1 , wherein the coupling member has a coupling head on one end close to the coupling head body, the coupling head has a screw bore to be fastened to the second screw thread of the rotary bolt.  
   
   
       4 . The water outlet coupling head of  claim 1 , wherein the coupling head body has a first screw thread on the periphery to be fastened to the spout of the water outlet head.  
   
   
       5 . The water outlet coupling head of  claim 1 , wherein the first end perimeter and the second end perimeter of the rotary bolt are coupled with at least one water sealing ring.  
   
   
       6 . The water outlet coupling head of  claim 1 , wherein the coupling head body is coupled with at least one water sealing ring on the outer perimeter thereof.  
   
   
       7 . The water outlet coupling head of  claim 1 , wherein the thrust member is a spring.
