Protective case

Abstract

A protective case includes a main body and a fixing strap. The fixing strap includes a first elastic part, a second elastic part and a connecting part. The first elastic part and the second elastic part are respectively connected with two lateral sides of an inner surface of the main body. The first elastic part and the second elastic part have plural openings, so that the elastic forces of the first elastic part and the second elastic part are adjustable. The connecting part is connected with the first elastic part and the second elastic part. The connecting part is accommodated within a hollow portion of the main body, and coplanar with an outer surface of the main body. When the connecting part is pulled, the first elastic part and the second elastic part deform, so that an object is held between the connecting part and the main body.

What is claimed is: 
     
         1 . A protective case, comprising:
 a main body, wherein an electronic device is installed on the main body;   a fixing strap disposed on the main body for holding an object between the fixing strap and the main body, wherein the fixing strap comprises:
 a first elastic part connected with an inner surface of the main body, and comprising at least one first opening, wherein an elastic force of the first elastic part is adjustable through the at least one first opening; 
 a second elastic part connected with the inner surface of the main body, and comprising at least one second opening, wherein an elastic force of the second elastic part is adjustable through the at least one second opening; and 
 a connecting part arranged between the first elastic part and the second elastic part and connected with the first elastic part and the second elastic part, wherein when the connecting part is not pulled, the connecting part is accommodated within a hollow portion of the main body and exposed to an outer surface of the main body, and the connecting part is coplanar with the outer surface of the main body, 
 wherein when the connecting part is pulled, the first elastic part and the second elastic part are stretched and subjected to deformation, so that the object is held between the connecting part and the main body. 
   
     
     
         2 . The protective case according to  claim 1 , wherein the at least one first opening and the at least one second opening have the same number and the same shape. 
     
     
         3 . The protective case according to  claim 1 , wherein the at least one first opening and the at least one second opening are circular or oblong. 
     
     
         4 . The protective case according to  claim 1 , wherein the connecting part is made of a non-elastic material, and the first elastic part and the second elastic part are made of silicon resin. 
     
     
         5 . The protective case according to  claim 1 , wherein the main body further comprises a stopping plate under the hollow portion, wherein two parallel rims of the stopping plate are connected with two corresponding parallel rims of the hollow portion, and two connection holes are respectively located at two opposite sides of the stopping plate. 
     
     
         6 . The protective case according to  claim 5 , wherein the first elastic part and the second elastic part are introduced into the main body through the corresponding connection holes. 
     
     
         7 . The protective case according to  claim 1 , wherein the main body further comprises at least one first locking slot, and the first elastic part comprises at least one first bulge, wherein the at least one first locking slot is located at a first lateral side of the inner surface of the main body, and the at least one first bulge is locked into the at least one first locking slot and fixed at the first lateral side of the main body. 
     
     
         8 . The protective case according to  claim 1 , wherein the main body further comprises at least one second locking slot, and the second elastic part comprises at least one second bulge, wherein the at least one second locking slot is located at a second lateral side of the inner surface of the main body, and the at least one second bulge is locked into the at least one second locking slot and fixed at the second lateral side of the main body. 
     
     
         9 . The protective case according to  claim 1 , wherein the connecting part comprises at least one first connecting groove, and the first elastic part comprises at least one first connecting block locked into the at least one first connecting groove. 
     
     
         10 . The protective case according to  claim 1 , wherein the connecting part comprises at least one second connecting groove, and the second elastic part comprises at least one second connecting block locked into the at least one second connecting groove. 
     
     
         11 . The protective case according to  claim 1 , wherein two ends of the first elastic part and two ends of the second elastic part are attached on the connecting part and the inner surface of the main body via an adhesive. 
     
     
         12 . The protective case according to  claim 1 , further comprising a covering plate, wherein the covering plate is coupled with the inner surface of the main body.
