Body shell structure for toy gun

Abstract

A body shell structure for toy gun (air soft gun BB-gun) formed of two half shells and defining therein a barrel-like upper chamber for accommodating a bullet firing unit and a lower chamber for accommodating a trigger, a transmission mechanism and a bullet supply unit, having horizontal coupling grooves and horizontal coupling ribs formed on the two half shells above the elevation of the barrel-like upper chamber and vertical engagement blocks and vertical engagement holes formed on the two half shells in front of the upper chamber such that the respective horizontal coupling ribs engage the respective horizontal coupling grooves and the respective vertical engagement blocks engage the respective vertical engagement holes to secure the two half shells firmly together against impact during forward stroke the piston of the bullet firing unit.

1 . A body shell structure for toy gun, comprising two half shells abutted together and defining therein a barrel-like upper chamber for accommodating a bullet firing unit and a lower chamber in communication with said barrel-like upper chamber for accommodating a trigger, a transmission mechanism and a bullet supply unit, a plurality of horizontal coupling grooves disposed at a sidewall of one of said two half shells above the elevation of said barrel-like upper chamber, and a plurality of horizontal coupling ribs disposed at a side wall of the other of said two half shells above the elevation of said barrel-like upper chamber for engaging said horizontal coupling grooves to secure said two half shells together;
 wherein said two half shells have at least one engagement block and at least one engagement hole disposed in front of said upper chamber in such a manner that the at least one engagement block engages the at least one engagement hole to reinforce the structural strength of said body shell structure when said horizontal coupling ribs and said horizontal coupling grooves are coupled together to secure said two half shells together.   
   
   
       2 . The body shell structure for toy gun as claimed in  claim 1 , wherein said at least one engagement block and said at least one engagement hole respectively extend in vertical direction. 
   
   
       3 . The body shell structure for toy gun as claimed in  claim 2 , wherein said horizontal coupling ribs, said horizontal coupling grooves, said at least one engagement block and said at least one engagement hole are disposed inside said two half shells and kept from sight when said two half shells are fastened together. 
   
   
       4 . The body shell structure for toy gun as claimed in  claim 2 , wherein said horizontal coupling ribs and said horizontal coupling grooves are disposed inside said two half shells; said at least one engagement block and said at least one engagement hole respectively extend to the outside of said two half shells.
