Simulated branch and simulated christmas tree

Abstract

The invention discloses a simulated branch and simulated Christmas tree. The simulated branch of the present invention includes a trunk and twigs and leaves; the simulated branch is integrally injection-molded with sun-proof plastic, a core strip inside the branch is wrapped by injection molding, and an assembled exposed portion of an inner core of the trunk also has a baking paint layer that is in sealing engagement with an injection molding layer, so that the entire branch forms a sealing waterproof and rust-proof structure with good waterproof, rust-proof and sun-proof effects. The simulated Christmas tree of the present invention is assembled by sealed plugging of a branch into a trunk, the entire simulated Christmas tree has good waterproof, rust-proof and sun-proof effects, and the branch is the above-mentioned simulated branch, which is convenient for transportation and transfer and has a high recycling rate.

What is claimed is: 
     
         1 . A simulated branch, comprising a trunk and twigs and leaves; the trunk comprising an inner core and an outer skin layer, and the outer skin layer being wrapped outside the inner core; the twigs and leaves comprising twigs and leaves, the twigs comprising skin layers, the leaves being connected to the skin layers of the twigs by integral injection molding, and the skin layers of the twigs being connected to the outer skin layer of the trunk by integral injection molding. 
     
     
         2 . The simulated branch according to  claim 1 , wherein the inner core has an assembly end protruding from the outer skin layer, the assembly end of the inner core has a baking paint layer, and the baking paint layer is in sealing engagement with the outer skin layer. 
     
     
         3 . The simulated branch according to  claim 1 , wherein the twigs have embedded cores; the skin layers of the twigs are wrapped outside the embedded cores. 
     
     
         4 . A simulated Christmas tree, comprising a trunk and a branch, and the branch being the simulated branch according to  claim 1 ; the trunk comprising a bark layer, and the bark layer having a plug-in portion; the plug-in portion having a plug-in hole, and the branch being pluggable into the plug-in hole;
 a trunk of the branch having a first sealing structure, and the plug-in portion having a second sealing structure corresponding to the first sealing structure; when the branch is plugged into the plug-in hole, the first sealing structure cooperating with the second sealing structure to seal the plug-in hole.   
     
     
         5 . The simulated Christmas tree according to  claim 4 , wherein the first sealing structure comprises a plurality of ring gears protruding toward the plug-in portion, and the plurality of ring gears are sequentially distributed along a radial direction;
 the second sealing structure includes a plurality of tooth spaces corresponding to the plurality of the ring gears one-to-one.   
     
     
         6 . The simulated Christmas tree according to  claim 5 , wherein an outermost ring gear of the first sealing structure is a first ring gear, and a raised height of the first ring gear is greater than a height of remaining ring gears; an outer periphery of the plug-in portion has a groove correspondingly matched to the first ring gear. 
     
     
         7 . The simulated Christmas tree according to  claim 5 , wherein the trunk of the branch has a locking structure protruding along a radial direction, and an inner wall of the plug-in hole has a locking guide groove adapted to the locking structure; the locking guide groove has an extension length along a circumferential direction, and the locking guide groove has an inclination angle relative to a plug-in axial direction;
 the inner wall of the plug-in hole also has a plug-in guide groove along the plug-in axial direction, the plug-in guide groove is adapted to the locking structure, and the plug-in guide groove and the locking guide groove are connected.   
     
     
         8 . The simulated Christmas tree according to  claim 7 , wherein the inclination angle of the locking guide groove is 5-10°. 
     
     
         9 . The simulated Christmas tree according to  claim 7 , wherein the locking guide groove at least comprises two locking guide grooves symmetrically distributed along the plug-in guide groove. 
     
     
         10 . The simulated Christmas tree according to  claim 4 , wherein the leaves of the branch, the skin layers of the twigs, the outer skin layer of the trunk, and the bark layer of the trunk are all made of sun-proof plastic;
 by mass percentage, the sun-proof plastic is composed of 96-97% resin matrix, 1.5-2.0% phenyl salicylate, 0.8-1.3% titanium dioxide powder, and 0.5-1.0% zinc oxide powder.
