Fastening belt capable of disassembling

Abstract

A fastening belt capable of disassembling, comprises a belt with selective length having a plurality of parallelly disposed teeth recesses provided on its end surface, a fastening socket with an inlet port on one end and another inlet port and an outlet port on the other end, in which an upper-side ratchet piece and a lower-side ratchet piece, facing oppositely each other, are extended from opposite side walls respectively. A plurality of ratchet teeth are provided on each ratchet piece respectively. The fixed end of fastening belt is clipped on the lower-side ratchet piece, while the free end of the same is clipped on the upper-side ratchet piece. A recess of each ratchet piece is formed at the base portion so as to provide each ratchet piece with resiliency which enables the fastening belt disassembled and re-use thereby.

         1 . A fastening belt capable of disassembling, comprising a belt with selective length having a plurality of parallelly disposed teeth recesses at equal distance provided on its top end surface, a fastening socket for clipping at both ends of said belt, characterized in that: 
 said fastening socket has an inlet port on one end and another inlet port and an outlet port on the other end, in which an upper-side ratchet piece and a lower-side ratchet piece, facing oppositely each other, are extended inwardly from opposite side walls respectively, and a plurality of ratchet teeth being provided on each ratchet piece respectively, the fixed end of said belt is clipped on the lower-side ratchet piece, while the free end of the same is clipped on the upper-side ratchet piece.    
     
     
         2 . The fastening belt capable of disassembling in accordance with  claim 1 , wherein a guiding plate with inclined surface is provided at the inner side of said inlet port below said upper-side ratchet piece.  
     
     
         3 . The fastening belt capable of disassembling in accordance with  claim 1 , wherein said upper-side and lower-side ratchet piece is formed into an overlapped structure.  
     
     
         4 . The fastening belt capable of disassembling in accordance with  claim 1 , wherein an included angle is formed between the upper end surface of said lower-side ratchet piece and the horizontal line of said fastening socket, said ratchet teeth of said upper-side ratchet piece being corresponding to said included angle.  
     
     
         5 . The fastening belt capable of disassembling in accordance with  claim 4 , wherein said included angle is approximately between 5° and 20°, preferably 10°.  
     
     
         6 . The fastening belt capable of disassembling in accordance with  claim 1 , wherein a recess is formed on the base portion of said ratchet pieces.  
     
     
         7 . The fastening belt capable of disassembling in accordance with  claim 1 , wherein a guiding inclined surface is formed on the bottom end surface of said ratchet teeth in the inserting direction of said belt, and an abutting surface being formed on the front end of said ratchet teeth in the clipping direction of said belt.  
     
     
         8 . The fastening belt capable of disassembling in accordance with  claim 1 , wherein said abutting surface is an acute angle or right angle.  
     
     
         9 . The fastening belt capable of disassembling in accordance with any one of  claim 1  to  claim 8 , wherein the number of ratchet teeth of said ratchet pieces is single or plural.  
     
     
         10 . A fastening belt capable of disassembling, comprising a belt with selective length having a plurality of parallelly disposed teeth recesses at equal distance provided on its top end surface, a fastening socket for clipping at both ends of said belt, characterized in that: 
 said fastening socket is formed as a double-layer structure, both ends of which is formed with an inlet port and an outlet port respectively, and two opposite ratchet pieces with slanted side are formed respectively from the top walls of the upper-layer metal part and lower-layer metal part by punching operation, the fixed end of said belt being clipped on the lower-layer ratchet piece, while the free end being clipped on the upper-layer ratchet piece.    
     
     
         11 . The fastening belt capable of disassembling in accordance with  claim 10 , wherein said fastening socket is the double-layer structure formed by the combination of two metal parts with its cross section in rectangular shape.  
     
     
         12 . The fastening belt capable of disassembling in accordance with  claim 1  or  claim 10 , wherein said belt can be produced consecutively with extrusion molding method and can be duly cut to selective length.  
     
     
         13 . The fastening belt capable of disassembling in accordance with  claim 12 , wherein the included angle of tooth portion formed between two teeth recesses has its value 1°<θ<90° preferably between 1° and 20°.
