Sliding rail

Abstract

comprising sliding rails includes a base, a connecting piece, a plurality of elastic pieces and a slider. The connecting piece passes through the elastic pieces and the slider, and is fixedly mounted on the base. The base has a pair of sliding chutes and a plurality of block pieces. The slider has a pair of sliding strips and a plurality of plates. The elastic pieces are located between the block pieces and the plates. The slider is accommodated in the sliding chutes via the sliding strips and slides on the base along the sliding chutes. After the slider slides for a certain distance relative to the base, the elastic pieces makes the slider to back to the original position.

What is claimed is: 
     
         1 . A sliding rail, comprising
 a base, comprising:
 a pair of sliding chutes; and 
 a plurality of block pieces; 
   a slider, comprising:
 a pair of sliding strips accommodated in the pair of sliding chutes and configured to slide on the base in the pair of sliding chutes; and 
 a plurality of plates; 
   a plurality of elastic pieces located between the plurality of block pieces and the plurality of plates; and   a connecting piece fixedly mounted on the base and configured to pass through the plurality of elastic pieces and the slider,   wherein, after the slider slides for a distance relative to the base, the plurality of elastic pieces returns the slider back to an original position.   
     
     
         2 . The sliding rail according to  claim 1 , wherein the base or the slider is subjected to electroplating treatment, or both are subjected to the electroplating treatment. 
     
     
         3 . The sliding rail according to  claim 1 , wherein the slider is configured to slide to two ends of the base respectively along the pair of sliding chutes. 
     
     
         4 . The sliding rail according to  claim 3 , wherein the plurality of block pieces are located at the two ends of the base and each of the plurality of block pieces is provided with a mounting hole,
 wherein each of the plurality of plates is extended and bent from a top of the slider downwards; and   wherein each of the plurality of plates includes a through hole.   
     
     
         5 . The sliding rail according to  claim 4 , wherein the connecting piece passes through the plurality of elastic pieces and the through holes of the plurality of plates, and is fixedly mounted on mounting holes of the plurality of block pieces. 
     
     
         6 . The sliding rail according to  claim 4 , wherein the plurality of plates comprises two plates provided on the slider, and
 wherein the plurality of elastic pieces comprises two elastic pieces provided on the slider corresponding to the two plates.   
     
     
         7 . The sliding rail according to  claim 1 , wherein the connecting piece is a cylindrical shaft. 
     
     
         8 . The sliding rail according to  claim 1 , wherein the elastic pieces are springs.
