Joint structure and method for assembling a joint structure

Abstract

A joint structure installed in the physical structure is provided. The joint structure includes a first latching member and a second latching member. The first latching member includes a first main body, a head portion extending from the first main body and a first convex portion extending from the first main body. The second latching member includes a second main body, a second convex portion extending from the second main body and a third convex portion extending from the second main body. When the first latching member and the second latching member are in an assembling status, the first convex portion slides between the second convex portion and the third convex portion.

What is claimed is: 
     
         1 . A joint structure, comprising:
 a first latching member, comprising a first main body, a headend extending from the first main body, and a first convex portion extending from the first main body; and   a second latching member, comprising a second main body, a second convex portion extending from the second main body, and a third convex portion extending from the second main body;   wherein, when the first latching member and the second latching member are in an assembling status, the first convex portion is configured to slide between the second convex portion and the third convex portion.   
     
     
         2 . The joint structure of  claim 1 , wherein the headend and the first convex portion are extended from the first main body along a first direction; the second convex portion and the third convex portion are extended from the second main body along a second direction, and the first direction and the second direction are reversed. 
     
     
         3 . The joint structure of  claim 1 , wherein when the first latching member and the second latching member are in the assembling status, the first latching member is configured to rotatably engage the first convex portion to a concave portion, and the concave portion is formed between the second convex portion and the third convex portion. 
     
     
         4 . The joint structure of  claim 3 , wherein the first convex portion includes a first inner side edge and a first outer side edge; the first inner side edge and the first outer side edge are an arc-shaped; the first inner side edge includes a first curvature rate; the first outer side edge includes a second curvature rate, and the first curvature rate is larger than the second curvature rate. 
     
     
         5 . The joint structure of  claim 4 , wherein the headend includes a circular side; the circular side includes a third curvature rate, and the third curvature rate is larger than the first curvature rate. 
     
     
         6 . The joint structure of  claim 5 , wherein the second convex portion includes a second inner side edge and a second outer side edge; the second inner side edge and the second outer side edge are the arc-shaped; the second inner side edge includes the third curvature rate; the second outer side edge includes the second curvature rate. 
     
     
         7 . The joint structure of  claim 6 , wherein the third convex portion includes a third inner side edge; the third inner side edge is the arc-shaped; the third inner side edge includes the second curvature rate. 
     
     
         8 . The joint structure of  claim 7 , wherein when the first latching member and the second latching member are in the assembling status, the circular side of the headend abuts against the second inner side of the second convex portion, and the first convex portion is slidably engaged with the concave portion by utilizing a rotation method with the headend as a rotation center. 
     
     
         9 . The joint structure of  claim 7 , wherein when the first latching member and the second latching member are in the assembling status, the second inner side of the second convex portion abuts against the circular side of the headend, and the second convex portion is slidably engaged between the headend and the first convex portion by utilizing a rotation method with the headend as a rotation center.
