Hanging hook structure

Abstract

Hanging hook structure including a hook body, two casings mated with each other, a press rod, a compression spring and a restoring spring. A slide stem downward extends from lower side of the hook body and is formed with a plane attaching face on one side. An upper rear side of the slide stem is formed with an escape recess. A stop block is formed under the escape recess. A front side of the slide stem is formed with an insertion notch. A lower end of the slide stem is formed with a restoring spring pushing cavity under the insertion notch. An inner side of each casing is cut with a slide channel and a push channel to form a cross shape. An upper end of one side of the slide channel is provided with a projecting stop block (or a dent). A lower end of the slide channel is formed with a restoring spring retaining section. A front section of the push channel is formed with a compression spring retaining section. A rear section thereof is provided with a diaphragm formed with an arched notch. The inner faces of the casings are formed with several mortises and tapered tenons. A rear end of the press rod is connected with a press head. A middle portion of the press rod is cut with an engaging recess. A front end of the engaging recess is formed with an engaging block. A front end face of the press rod is formed with a compression spring retaining face.

What is claimed is:  
     
         1 . Hanging hook structure comprising a hook body, two casings mated with each other, a press rod, a compression spring and a restoring spring, the hook body being formed with an opening on upper front face, a hooking section being formed on inner side of the opening, an upper front side of each casing having an upward extending stop block corresponding to the opening of the hook body, said hanging hook structure being characterized in that: 
 a slide stem downward extends from lower side of the hook body, one side of the slide stem being formed with a plane a attaching face, an upper rear side of the slide stem being formed with an escape recess, a stop block being formed under the escape recess, a middle portion of front side of the slide stem being formed with an insertion notch, a lower end of the slide stem being formed with a restoring spring pushing cavity under the insertion notch;    an inner side of each casing is cut with a slide channel and a push channel communicating with the slide channel to form a cross shape, an upper end of one side of the slide channel being provided with a projecting stop block (or a dent corresponding to the stop block, a lower end of the slide channel being formed with a restoring spring retaining section, a front section of the push channel in front of the slide channel being formed with a compression spring retaining section, a rear section thereof being provided with a diaphragm dividing the rear section into a large receiving space and a small receiving space at the opening of the push channel, the diaphragm being formed with an arched notch, the inner faces of the casings being formed with several mortises and tapered tenons surrounding the slide channel and the push channel;    a rear end of the press rod is connected with a press head, a middle portion of the press rod being cut with an engaging recess, a front end of the engaging recess being formed with an engaging block, a front end face of the press rod being formed with a compression spring retaining face, the slide stem of the hook body and the restoring spring being placed in the slide channel of the casing, the press rod and the compression spring being placed in the push channel of the casing, the two casings being mated with each other to integrally associate with the hook body.    
     
     
         2 . Hanging hook structure as claimed in  claim 1 , wherein the casings are mated with each other in such a manner that the tapered tenons are forcedly tightly fitted into the mortises so as to firmly associate the two casings with each other.
