Abstract

A protecting case comprises an upper protecting element and a lower protecting element that are both in the form of a hollow frame. The upper protecting element is shaped and sized to be closely fitted on an upper portion of a to-be-protected product while the lower protecting element is shaped and sized to be closely fitted on a lower portion of the to-be-protected product. The upper protecting element is formed with an upper engaging portion and a groove, and the lower protecting element being formed with a lower engaging portion and a rib. The upper protecting element is engaged on the upper portion of the to-be-protected product through the upper engaging portion. The lower protecting element is engaged on the lower portion of the to-be-protected product through the lower engaging portion. The upper and the lower protecting elements are engaged to each other through the groove and the rib.

1 . A protecting case comprising:
 an upper protecting element the form of a hollow frame including a rectangular upper engaging portion around a top thereof in such a manner that a top opening of the upper protecting element is smaller than a bottom opening of the upper protecting element, adjacent to the bottom opening of the upper protecting element being annularly provided a groove around an inner periphery of the upper protecting element, the upper protecting element being engaged on a to-be-protected product through the bottom opening of the upper protecting element in such a manner that the upper engaging portion of the upper protecting element is closely fitted on a top outer periphery of the to-be-protected product; and   a lower protecting element in the form of a hollow frame including a rectangular lower engaging portion around a bottom thereof in such a manner that a bottom opening of the lower protecting element is smaller than a top opening of the lower protecting element, adjacent to the top opening of the lower protecting element being annularly provided a rib protruding from an outer periphery of the lower protecting element, the lower protecting element being engaged at a bottom of the to-be-protected product through the top opening of the lower protecting element in such a manner that the lower engaging portion of the lower protecting element is engaged on a bottom outer periphery of the to-be-protected product while the rib is engaged into the groove of the upper protecting element.   
     
     
         2 . The protecting case as claimed in  claim 1 , wherein the upper engaging portion of the upper protecting element is formed with a stepped frame body around the top thereof, the frame body has an arc surface to be fitted on an arc surface formed on a top circumference of an upper portion of the to-be-protected product. 
     
     
         3 . The protecting case as claimed in  claim 2 , wherein the whole lower protecting element is located at the lower portion of the to-be-protected product for fitting on the lower portion of the to-be-protected product. 
     
     
         4 . The protecting case as claimed in  claim 2 , wherein the bottom opening of the lower protecting element is formed as a closed solid structure
