Casing structure

Abstract

A casing structure includes a case member and a sliding member. The case member includes a first case body and a second case body. The sliding member includes a first slider, a second slider, and a torsion spring. The first case body and the second case body may move relative to each other through the sliding member. The first slider includes a hollow part and a spring fixing part extending from an edge of the hollow part into the first case body. The torsion spring includes a spiral portion. The two ends of the torsion spring are respectively disposed on the spring fixing part and the second slider, and the spiral portion of the torsion spring corresponds to the hollow part, thus reducing an overall thickness of the casing structure.

1 . A casing structure, comprising:
 a case member, comprising a first case body and a second case body, wherein the first case body has a space; and   a sliding member, comprising a first slider, a second slider, and a torsion spring, wherein the first slider is disposed in the first case body, and the first slider comprises a hollow part and a spring fixing part extending from an edge of the hollow part into the space of the first case body, the second slider is disposed in the second case body, the torsion spring comprises a spiral portion, two ends of the torsion spring are respectively disposed on the spring fixing part and the second slider, and the spiral portion corresponds to the hollow part and is located in the hollow part.   
   
   
       2 . The casing structure according to  claim 1 , wherein a number of the hollow parts is two, the two hollow parts are symmetric to each other, and a number of the torsion springs is two. 
   
   
       3 . The casing structure according to  claim 1 , wherein the spring fixing part has a first fixing post, the second slider has a second fixing post, the first fixing post and the second fixing post are used for respectively connecting the two ends of the torsion spring. 
   
   
       4 . The casing structure according to  claim 3 , wherein numbers of the spring fixing parts, the first fixing posts, the second fixing posts, and the torsion springs are all two. 
   
   
       5 . The casing structure according to  claim 3 , wherein the torsion spring further comprises a first arm and a second arm, the first arm and the second arm are respectively connected to two ends of the spiral portion, and the first arm and the second arm are respectively connected to the first fixing post and the second fixing post. 
   
   
       6 . The casing structure according to  claim 1 , wherein the first slider has a slide track on its both sides respectively, and the second slider has two sliding slots at positions corresponding to the slide tracks and used for the slide tracks to slide therein.
