Adjustable device and an adjustable storage box

Abstract

The disclosure provides an adjustable device including plates and at least two adjustable modules connect with two adjacent of the plates. The adjustable module can stretch or shrink to change a distance between plates. The disclosure also provides an adjustable storage box including an upper cover and a lower cover. A storage space is formed by the upper cover and the lower cover and for the accommodating of the adjustable device. When the upper cover moves upward relative to the lower cover, the adjustable modules changes from a compression state to a stretch state and increase a distance between plates. Whereby, it is easy to pick and place object when a distance of two adjacent plates increases. The overall volume of the adjustable device is reduced when a distance of two adjacent plates decrease, thereby saving the working space.

1 . An adjustable storage device, comprising:
 plates, storing a plurality of plates; and   at least two adjustable modules, connecting a first plate and adjacent to which a second plate, the at least two adjustable modules being stretchable to change a distance between the first plate and the second plate, each of the at least two adjustable modules comprising:
 a first sidewall, comprising a right part, a left part, and a connection part connecting the right part and the left part, the right part comprising a right part upper pivot hole, a right part lower pivot hole, and a right part restriction trail adjacent to the right part lower pivot hole, the left part comprising a left part upper pivot hole, a left part lower pivot hole, and a left part restriction trail adjacent to the left part lower pivot hole; 
 two second sidewalls, each comprising an upper pivot hole, a lower pivot hole, a right restriction pin and a left restriction pin provided adjacent to the upper pivot hole and located on two sides of the second sidewall respectively; and 
 wherein the lower pivot hole of one of the two second sidewalls, the right part upper pivot hole and the left part upper pivot hole of the first sidewall being fixed to the first plate by a hinge, the right restriction pin and the left restriction pin of the other of the two second sidewalls extending into the right restriction trail and the left restriction trail of the first sidewall respectively, thus that when the at least two adjustable modules being in a compression state, two second sidewalls coming close to each other. 
   
     
     
         2 . The adjustable storage device of  claim 1 , wherein the upper pivot hole of the other of the two second sidewalls, the right part lower pivot hole and the left part pivot hole of the first sidewall being connected by another hinge. 
     
     
         3 . The adjustable storage device of  claim 1 , wherein the right part restriction trial, the left part restriction trial respectively forming a hollow design with the right part lower pivot hole and the left part pivot hole. 
     
     
         4 . The adjustable storage device of  claim 1 , wherein the right part restriction trial and the left part restriction trail being a caved design. 
     
     
         5 . The adjustable storage device of  claim 1 , wherein the connection part of the first sidewall connecting a center portion of the right part upper pivot hole and the right part lower pivot hole, and a center portion of the left part upper pivot hole and the left part lower pivot hole. 
     
     
         6 . The adjustable storage device of  claim 1  further comprising two springs respectively extending from the right part lower pivot hole and the left part lower pivot hole of the first sidewall into the upper pivot hole of the other of the two sidewalls, and providing an elastic tension to maintain the adjustable storage device in a compression state or a stretch state.
