Connection structure of module, storage box and storage box assembly

Abstract

A mating part in a locking path of a stop part so that the locking part is not automatically lockable and a first connection part is in a state of remaining unlocked from a second connection part.

1 . A storage box comprising:
 a first connection part disposed on one surface of said storage box;   a second connection part disposed on another surface of said storage box;   a stop part, wherein said first connection part comprises a mounting part, a locking part movable with respect to said mounting part, and a first resilient member located between said mounting part and said locking part, wherein said first resilient member keeping said locking part automatically in a locked state;   said second connection part comprises a mating part interlockable with the locking part, the locking part configured for being pressed down so that it is automatically locked with the mating part of another storage box by action of said first resilient member;   when said stop part is in the locking path of the locking part, said locking part is not automatically lockable and said first connection part is in a state of remaining unlocked from said second connection part.   
     
     
         2 . The storage box of  claim 1 , wherein the stop part is retractable, said stop part being extended when said first connection part is in a holding unlocked state with said second connection part, and said stop part being compressed when said first connection part is in a locked state with said second connection part. 
     
     
         3 . The storage box of  claim 2 , wherein said stop part is provided on said locking part and is movable with said locking part; said stop part holds the second connection part outward when said first connection part and said second connection part are in a holding unlocked state. 
     
     
         4 . The storage box of  claim 3 , wherein said stop part comprises a holding slot opened on the locking part, a card block that can be accommodated in said holding slot and a second resilient member; said holding slot has a bottom wall and two side walls, two said side walls extending upward along both sides of said bottom wall and set opposite each other. 
     
     
         5 . The storage box of  claim 3 , wherein the card block is rotatably connected to said locking part and the other end is retractably provided in said holding slot, said second resilient member keeping said card block automatically in an ejected state; when said card block is ejected and held against said mating portion, said locking part cannot be automatically locked and said first connection part and said second connection part in a state of remaining unlocked. 
     
     
         6 . The storage box of  claim 5 , wherein said second resilient member is a telescopic spring with one end against said card block and the other end against said bottom wall; when said second resilient member is popped out, said card block extends out of said holding slot and when said second resilient member is compressed, said card block is retracted into said holding slot. 
     
     
         7 . The storage box of  claim 5 , wherein said stop section further comprises a rotating shaft rotatably connected to said locking section, said ends of said rotating shaft being fixed to two said side walls; said second resilient member being a torsion spring, one end of said card block and said torsion spring being snapped onto said rotating shaft. 
     
     
         8 . The storage box of  claim 4 , wherein said card block is always located in said holding slot and the other end is retractably provided in said holding slot, said second resilient member keeping said card block automatically in the ejected state; when said card block is ejected and held against said mating part, said locking part cannot be automatically locked and said first connection part and said second connection part in a state of remaining unlocked. 
     
     
         9 . The storage box of  claim 8 , wherein said second resilient member is a telescopic spring with one end against said card block and the other end against said bottom wall; when said second resilient member is extended, said card block extends into the holding slot and when said second resilient member is compressed, said card block is compressed in the holding slot. 
     
     
         10 . The storage box of  claim 1 , wherein said locking part is a sliding latch for horizontal movement, a flipping latch for flipping movement or a rotating latch for rotating movement. 
     
     
         11 . The storage box of  claim 10 , wherein said first connection part is provided on a lid of said storage box and said second connection part is provided on the bottom of said storage box. 
     
     
         12 . The storage box of  claim 11 , wherein two adjacent said storage boxes are interlockable with each other by means of a first connection part and a second connection part. 
     
     
         13 . The storage box of  claim 1 , wherein the stop part comprises of a card block positioned in a slot and biased outward by the second resilient member. 
     
     
         14 . The storage box of  claim 13 , wherein the card block moves perpendicular with respect to a sliding path of the locking part. 
     
     
         15 . The storage box of  claim 14 , wherein the card block moves perpendicularly upward relative to the first connection part. 
     
     
         16 . The storage box of  claim 14 , wherein the card block moves perpendicularly downward relative to the first connection part. 
     
     
         17 . The storage box of  claim 13 , wherein the second resilient member is a torsion spring and the card block rotates upward relative to the first connection part. 
     
     
         18 . The storage box of  claim 13 , wherein the second resilient member is a telescopic spring and the card block rotates upward relative to the first connection part.
