Potable Straw

Abstract

A portable straw, including the limiting component, the adjusting component and the straw body. The said limiting component includes first limiting disc and second limiting disc which are mutually symmetrical and kept at a given gap. Both limiting discs are connected through a cylinder, and the first limiting disc, the second limiting disc and the cylinder are in a same axis, which eliminates the weakness of the prior straws of the environmental contamination, inconvenient carrying and fixed shape.

1 : A type of portable straw, which is characterized to include the limiting component, adjusting component and the straw body, the said limiting component includes the first limiting disc and the second limiting disc, which are mutually symmetrical and kept at a given gap, and the said first limiting disc and second limiting disc are connected through a cylinder.
 The said adjusting component includes the first adjusting disc and the second adjusting disc which are mutually symmetrical and able to relatively rotate, the said cylinder passes the center of the first adjusting disc and the second adjusting disc, the said first adjusting disc and the second adjusting disc are separately provided with the first connecting tube and the second connecting tube. The said first connecting tube and second connecting tube are sited by both sides of the cylinder, the tops of the said first connecting tube and the second connecting tube are connected through a foldable hose, and the bottom ends of the said first connecting tube and the second connecting tube separately insert into the straw body.   
     
     
         2 : The portable straw described in  claim 1 , which is characterized that the one side of the said first adjusting disc close to the second adjusting disc is provided with an annular groove, the inside of the said annular groove is fixed with a spring, the opening of the said annular groove is provided with the annular fixing disc to fix the groove, the said fixing disc is provided with several clamping pillars which pass the said fixing disc and are evenly arranged. The said clamping pillars can axially move, one end of the said clamping pillar sited in the clamping groove is connected with the spring, the side of the said second adjusting disc close to the first adjusting disc is provided with several clamping grooves, and the end of the said clamping pillar close to the second adjusting disc is spherically matched with the said clamping groove. 
     
     
         3 : The portable straw described in  claim 1 , which is characterized that the said cylinder includes the key extending from the center of the first limiting disc towards the second limiting disc, and also includes the plug, the end of the said plug close to the first limiting disc can pass the center of the second limiting disc and insert into the key, and another end of the plug is clamped with the second limiting disc. 
     
     
         4 : The portable straw described in  claim 1 , which is characterized that the outer wall of the connection end of the said foldable hose is provided with several annular projections, and the said foldable hose can insert into the first connecting tube and the second connecting tube. 
     
     
         5 : The portable straw described in  claim 1 , which is characterized that the outer walls of the bottom ends of the said first connecting tube and the second connecting tube are provided with several annular grooves, and the inside of the said annular groove is provided with water-sealing rings. 
     
     
         6 : The portable straw described in  claim 1 , which is characterized that slides are fixed between the said first limiting disc and the first adjusting disc and between the second adjusting disc and the second limiting disc. 
     
     
         7 : The portable straw described in  claim 1 , which is characterized that the outer sides of both the first limiting disc and the second limiting disc are provided with cover plates. 
     
     
         8 : The portable straw described in  claim 1 , which is characterized that the said foldable hose is made of silicone.
