Tree cap with no-bolt connection

Abstract

A tree cap includes a tree cap body, a blanking plug positioned adjacent the tree cap body and at least partially received within the tree cap body, a hold down cap nut in axial alignment with the blanking plug and the tree cap body along a tree cap body axis, the hold down cap nut engaged with the tree cap body and the blanking plug to limit axial movement of the blanking plug, and a quick connection system. The quick connection system includes tree cap body lugs extending radially outward from the tree cap body and cap nut lugs extending radially inward from the hold down cap nut. When the tree cap body lugs are circumferentially aligned with the cap nut lugs, interference between the tree cap body lugs and the cap nut lugs limits axial movement of the hold down cap nut.

         7 . The tree cap of  claim 1 , wherein the one or more tree cap body lugs engage the one or more cap nut lugs, causing the hold down cap nut to retain force on the blanking plug and securing the blanking plug in place in the tree cap. 
     
     
         8 . The tree cap of  claim 1 , wherein the one or more tree cap body lug rows of the quick connection system comprises:
 a first row of tree cap body lugs; and   a second row of tree cap body lugs, wherein the first row of tree cap body lugs is aligned substantially oblique to the second row of tree cap body lugs.   
     
     
         9 . The tree cap of  claim 1 , wherein the one or more cap nut lug rows of the quick connection system comprises:
 a first row of cap nut lugs; and   a second row of cap nut lugs, wherein the first row of cap nut lugs is aligned substantially oblique to the second row of cap nut lugs.   
     
     
         10 . The tree cap of  claim 1 , wherein the one or more tree cap body lug rows of the quick connection system comprises; and
 a second row of tree cap body lugs, wherein the first row of tree cap body lugs is aligned substantially parallel to the second row of tree cap body lugs.   
     
     
         11 . The tree cap of  claim 1 , wherein the one or more cap nut lug rows of the quick connection system comprises:
 a first row of cap nut lugs; and   a second row of cap nut lugs, wherein the first row of cap nut lugs is aligned substantially parallel to the second row of cap nut lugs.   
     
     
         12 . A tree cap, comprising:
 a tree cap body having an open end;   a blanking plug;   a hold down cap nut in axial alignment with the blanking plug and the tree cap body, the hold down cap nut engaged with the tree cap body and the blanking plug to limit axial movement of the blanking plug relative to the tree cap body; and   a quick connection system configured to secure the blanking plug to the tree cap body, comprising:
 a tree cap body lug extending radially outward from the tree cap body; 
 a cap nut lug extending radially inward from the hold down cap nut, the cap nut lug at least partially axially aligned with and configured to engage the tree cap body lug to limit relative axial movement between the tree cap body and the hold down cap; and 
 a latch configured to prevent rotational movement of the hold down cap nut relative to the tree cap body. 
   
     
     
         13 . The tree cap of  claim 12 , wherein the tree cap body lug engages the cap nut lug, causing the hold down cap nut to retain force on the blanking plug and securing the blanking plug in place in the open end of the tree cap body. 
     
     
         14 . The tree cap of  claim 12 , wherein the latch comprises a latch member, the latch member causing the hold down cap nut to retain force on the blanking plug and securing the blanking plug in place in the open end of the tree cap body. 
     
     
         15 . The tree cap of  claim 12 , wherein the quick connection system further comprises:

         16 . An assembly, comprising:
 a composite block; and   a tree cap, comprising:
 a tree cap body having an open end; 
 a blanking plug positioned adjacent the tree cap body and at least partially received within the open end of the tree cap body; 
 a hold down cap nut in axial alignment with the blanking plug and the tree cap body along a tree cap body axis, the hold down cap nut engaged with the tree cap body and the blanking plug to limit axial movement of the blanking plug relative to the tree cap body; and
