Pressure control box used for transporting objects

Abstract

A pressure control box used for transporting objects includes a main body and a cover. The main body has a containing space and includes a pressure valve installed on a side of the main body and communicated with the containing space and an external space of the main body for externally connecting a pressure controller to adjust an internal pressure. The cover covers the opening position of the containing space for sealing the containing space, and the cover has a seal embedded into the inner surface of the cover, so that the cover and the main body are sealed with each other. Therefore, the pressure control box can be used for transporting goods stored at a constant pressure to maintain the quality of goods and improve the efficiency and safety of the goods delivery.

What is claimed is: 
     
         1 . A pressure control box used for transporting objects, comprising:
 a main body, having a containing space, and including at least a pressure valve installed on a side of the main body and communicated with the containing space and an external space of the main body for connecting to a pressure controller externally to adjust a pressure in the pressure control box used for transporting objects; and   a cover, covered onto an opening of the containing space for sealing the containing space, and the cover having at least a seal embedded into an inner surface of the cover, so that the cover and the main body are sealed with each other.   
     
     
         2 . The pressure control box used for transporting objects according to  claim 1 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         3 . The pressure control box used for transporting objects according to  claim 1 , wherein the cover further includes at least a buffer. 
     
     
         4 . The pressure control box used for transporting objects according to  claim 3 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         5 . The pressure control box used for transporting objects according to  claim 3 , wherein the buffer is a spring. 
     
     
         6 . The pressure control box used for transporting objects according to  claim 5 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         7 . The pressure control box used for transporting objects according to  claim 3 , wherein the main body further comprises at least a circulating member installed on an inner side, a bottom, or both of the inner side and bottom of the main body. 
     
     
         8 . The pressure control box used for transporting objects according to  claim 7 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         9 . The pressure control box used for transporting objects according to  claim 7 , wherein the circulating member is a meshed structure, a porous structure, or a protruded structure. 
     
     
         10 . The pressure control box used for transporting objects according to  claim 9 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         11 . The pressure control box used for transporting objects according to  claim 7 , wherein the cover further includes a ring protrusion with the seal embedded therein. 
     
     
         12 . The pressure control box used for transporting objects according to  claim 11 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         13 . The pressure control box used for transporting objects according to  claim 11 , wherein the main body further has at least a rib installed at a side edge of the main body for blocking a side of the ring protrusion. 
     
     
         14 . The pressure control box used for transporting objects according to  claim 13 , further comprising at least a pressure indicator installed on a side of the main body. 
     
     
         15 . The pressure control box used for transporting objects according to  claim 14 , wherein the main body further has at least a latching portion disposed on an outer side of the main body, and the cover further has at least a fastener installed on an outer side of the cover, and the fastener is correspondingly fastened to the latching portion. 
     
     
         16 . The pressure control box used for transporting objects according to  claim 15 , wherein the cover has a side edge pivotally coupled to a side edge of the main body. 
     
     
         17 . The pressure control box used for transporting objects according to  claim 16 , further comprising at least a carrier mounted onto a side of the cover for carrying and stacking an object. 
     
     
         18 . The pressure control box used for transporting objects according to  claim 1 , wherein the main body further has at least a projection formed and extended from an inner side of a bottom of the main body. 
     
     
         19 . The pressure control box used for transporting objects according to  claim 1 , wherein the main body and the cover are made of metal.
