Bag for digital devices with Self-lock High-pressure Sealing Device

Abstract

This invention is related to a bag for digital devices with self-lock high-pressure sealing device, including lock body and core. The lock body has a long cylinder with a long groove at one side. The width of the groove is smaller than that of the lock core. Both sides of the groove have slope inside. The lock core is located in the long cylinder. The lock core and lock body are fixed by a positioning mechanism making the two interact with a proper clearance which is smaller than the thickness of the bag for digital devices. The invention utilizes the interaction between the lock body and the lock core to clamp the opening of the bag for digital devices and make it sealed for effective waterproof.

1 . A bag for digital devices with self-lock high-pressure sealing device, including the lock body ( 1 ) and lock core ( 2 ), characterized in that the lock is with a long cylinder ( 11 ) with a groove ( 12 ) at one side; the width of the groove ( 12 ) is smaller than that of the lock core ( 2 ); at the inner side of both sides of the groove ( 12 ), there is a slope ( 13 ); the lock core ( 2 ) is located in the long cylinder ( 11 ); the lock core ( 2 ) and lock body ( 1 ) are fixed by a positioning mechanism making the two interact and with a proper clearance in-between; and
 the clearance is smaller than the thickness of the bag for digital devices ( 3 ).   
     
     
         2 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 1 , characterized in that the positioning mechanism includes the core locating hole ( 14 ) at one end (outside) of the lock body ( 1 ) and the dowel pin ( 21 ) at the end of lock core ( 2 ); and the locating hole ( 14 ) and dowel pin ( 21 ) interact with each other to make the lock core ( 2 ) suspend in the cylinder ( 11 ). 
     
     
         3 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 2 , characterized in that the inner wall at the lock body ( 1 ) ends has a spherical surface ( 15 ); the end of the lock core ( 2 ) where no dowel pin ( 21 ) is set has a curve structure; and at the end of this curve structure, there is a round ball ( 22 ). 
     
     
         4 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 3 , characterized in that the above-mentioned curve structure has a gradient of 30°. 
     
     
         5 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 1 , characterized in that the slope at the inner side of both sides of the groove ( 12 ) is angled at 30°. 
     
     
         6 . The bag for digital devices with self-lock high-pressure sealing device described in  claim 1 , characterized in that the lock core ( 2 ) is of triangular structure being composed of three strings of different thickness, height and angles. 
     
     
         7 . The bag for digital devices with self-lock high-pressure sealing device as set forth  claim 2 , characterized in that at the end of lock core ( 2 ) where the dowel pin ( 21 ) is made, there is a spacing sheet ( 23 ). 
     
     
         8 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 1 , characterized in that a hanging loop ( 16 ) is made at the lock body ( 1 ). 
     
     
         9 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 1 , characterized in that a baffle ( 17 ) is set in the tangential direction along the side of the cylinder ( 11 ); and the groove ( 12 ) is below the baffle ( 17 ). 
     
     
         10 . The bag for digital devices with self-lock high-pressure sealing device as set forth in  claim 1 , characterized in that the bag for digital devices ( 3 ) has a plastic seal at the opening.
