Drawer Adjusting Device

Abstract

A drawer adjusting device includes a fixed member having an adjusting hole. A movable member includes two limiting blocks spaced from each other by a gap. The movable member includes an upper pushing portion on a top end thereof and a lower pushing portion on a bottom end thereof. An adjusting member includes a first side having a control portion and a second side having a spiral block. A spacing between the spiral block and a central axis of the adjusting member gradually increases from an end of the spiral block toward another end of the spiral block. The adjusting member is located between the fixed member and the movable member. The control portion is received in the adjusting hole. The spiral block extends through the gap between the two limiting blocks.

What is claimed is: 
     
         1 . A drawer adjusting device comprising:
 a fixed member including an adjusting hole;   a movable member including two limiting blocks spaced from each other by a gap, with the movable member including an upper pushing portion on a top end thereof and a lower pushing portion on a bottom end thereof; and   an adjusting member including a first side having a control portion and a second side having a spiral block, with a spacing between the spiral block and a central axis of the adjusting member gradually increasing from an end of the spiral block toward another end of the spiral block, with the adjusting member located between the fixed member and the movable member, with the control portion received in the adjusting hole, and with the spiral block extending through the gap between the two limiting blocks.   
     
     
         2 . The drawer adjusting device as claimed in  claim 1 , wherein the fixed member includes a first sideboard insertion plate, a bottom board coupling plate connected to the first sideboard insertion plate, and a first tail board coupling plate connected to the first sideboard insertion plate, and wherein the adjusting hole is defined in the first sideboard insertion plate. 
     
     
         3 . The drawer adjusting device as claimed in  claim 2 , wherein the movable member includes a second sideboard insertion plate and a second tail board coupling plate connected to the second sideboard insertion plate, wherein the two limiting blocks and the upper pushing portion are disposed on the second sideboard insertion plate, and wherein the lower pushing portion is disposed on the second tail board coupling plate. 
     
     
         4 . The drawer adjusting device as claimed in  claim 3 , wherein the first sideboard insertion plate includes an opening, wherein a shield plate is fixed to an end of the opening and shields the end of the opening, defining a chamber in the first sideboard insertion plate, and wherein the adjusting hole extends through the shield plate. 
     
     
         5 . The drawer adjusting device as claimed in  claim 4 , wherein the second sideboard insertion plate of the movable member abuts the first sideboard insertion plate of the fixed member, and wherein the two limiting blocks are located in the chamber. 
     
     
         6 . The drawer adjusting device as claimed in  claim 3 , wherein the second tail board coupling plate of the movable member abuts the first tail board coupling plate of the fixed member, and wherein the first tail board coupling plate has a lower edge located above the lower pushing portion. 
     
     
         7 . The drawer adjusting device as claimed in  claim 2 , wherein the first tail board coupling plate is connected to an edge of the first sideboard insertion plate, wherein an extension extends outward from another edge of the first sideboard insertion plate, wherein a cap is coupled to the first sideboard insertion plate and includes a slit, and wherein the extension is securely engaged in the slit. 
     
     
         8 . The drawer adjusting device as claimed in  claim 1 , wherein the adjusting member includes a stopper block, and wherein the stopper block is spaced from and located outside of the spiral block.
