Hopper structure of paintball marker

Abstract

A hopper structure of a paintball marker includes a hopper body, a paintball holder, an upper cover, and first and second connecting elements. The hopper body has opposite first and second pivot portions. The first pivot portion has opposite and mutually communicating first pivot holes. The second pivot portion has opposite and mutually communicating second pivot holes. After a third pivot portion of the paintball holder is received in the first pivot portion, a fourth pivot portion of the upper cover is received in the second pivot portion. Thus, the paintball holder and the upper cover are stacked vertically on the hopper body. The upper cover, the paintball holder, and the hopper body are pivotally connected by the first and second connecting elements such that the assembled hopper structure is conveniently opened and closed and will not fall apart when accidentally dropped to the ground or hit during use.

1 . A hopper structure of a paintball marker, comprising:
 a hopper body having a first pivot portion and a second pivot portion opposite the first pivot portion, the first pivot portion having opposite and mutually communicating first pivot holes, the second pivot portion having opposite and mutually communicating second pivot holes, the hopper body being centrally provided with a receiving chamber connected with a paintball channel;   a paintball holder provided above the hopper body and having a third pivot portion, the third pivot portion being received in the first pivot portion of the hopper body, the third pivot portion having a first through hole corresponding in position to the first pivot holes of the first pivot portion, the paintball holder having a predetermined hole corresponding in position to the receiving chamber of the hopper body;   an upper cover provided above the paintball holder and having a fourth pivot portion, the fourth pivot portion being received in the second pivot portion of the hopper body, the fourth pivot portion having a second through hole corresponding in position to the second pivot holes of the second pivot portion, wherein a hopper lid is fittingly and pivotally provided on the upper cover and located above the predetermined hole of the paintball holder;   a first connecting element for connecting the hopper body with the paintball holder, the first connecting element having an end formed with a first threaded hole, the first threaded hole being threadingly connected to a first bolt, wherein the first connecting element connected with the first bolt passes through the first pivot holes of the first pivot portion and the first through hole of the third pivot portion; and   a second connecting element for connecting the hopper body with the upper cover, the second connecting element having an end formed with a second threaded hole, the second threaded hole being threadingly connected to a second bolt, wherein the second connecting element connected with the second bolt passes through the second pivot holes of the second pivot portion and the second through hole of the fourth pivot portion.   
     
     
         2 . The hopper structure of  claim 1 , wherein the first pivot portion is formed as two projecting plates. 
     
     
         3 . The hopper structure of  claim 1 , wherein the second pivot portion is formed as two projecting plates. 
     
     
         4 . The hopper structure of  claim 1 , wherein the hopper body has an outer surface provided with ribs between the first pivot portion and the second pivot portion. 
     
     
         5 . The hopper structure of  claim 1 , wherein the hopper body is provided with a resilient fastener extending upward from inside the receiving chamber. 
     
     
         6 . The hopper structure of  claim 5 , wherein the paintball holder has a fixing hole corresponding in position to the resilient fastener of the hopper body. 
     
     
         7 . The hopper structure of  claim 1 , wherein the paintball holder has an outer surface provided with at least a stud. 
     
     
         8 . The hopper structure of  claim 7 , wherein the upper cover is provided with at least an engaging hole corresponding in position to the at least a stud of the paintball holder. 
     
     
         9 . The hopper structure of  claim 1 , wherein the third pivot portion is provided with a pressing block perpendicular to the first through hole. 
     
     
         10 . The hopper structure of  claim 9 , wherein the upper cover is provided with an engaging block corresponding in position to the pressing block of the third pivot portion of the paintball holder. 
     
     
         11 . The hopper structure of  claim 1 , wherein the third pivot portion is formed as a block. 
     
     
         12 . The hopper structure of  claim 1 , wherein the fourth pivot portion is formed as an arcuate plate.
