Abstract

A connecting structure for a shoe drying machine, including wind pipes fixed at output ends of the shoe drying machine, and shoe supports detachably connected to the wind pipes; each of the shoe supports sleeves a peripheral surface of a corresponding wind pipe, and a side wall of each of the shoe supports is provided with a first connecting part; a side wall of each of the wind pipes is provided with a second connecting part, and the second connecting part of each wind pipe and the first connecting part of a corresponding shoe support are locked with respect to each other by rotation of the corresponding shoe support.

What is claimed is: 
     
         1 . A connecting structure for a shoe drying machine, comprising:
 wind pipes fixed at output ends of the shoe drying machine, and shoe supports detachably connected to the wind pipes, wherein each of the shoe supports sleeves a peripheral surface of a corresponding wind pipe, and a side wall of each of the shoe supports is provided with a first connecting part;   a side wall of each of the wind pipes is provided with a second connecting part, and the second connecting part of each wind pipe and the first connecting part of a corresponding shoe support are locked with respect to each other by rotation of the corresponding shoe support.   
     
     
         2 . The connecting structure of  claim 1 , wherein an upper end surface of each of the wind pipes is provided with a plurality of air outlets. 
     
     
         3 . The connecting structure of  claim 1 , wherein each first connecting part comprises a first axial groove extending along an axial direction of the shoe support, and a first circumferential groove disposed along a circumferential direction of the shoe support; a lower end of the first axial groove extends to a bottom end of the shoe support, and one end of the first circumferential groove is in communication with an upper end of the first axial groove; the second connecting part of each of the wind pipes comprises at least one first protruding piece arranged on an outer side wall of the wind pipe; when sleeving the shoe support on a corresponding wind pipe, the first protruding piece enters the first axial groove and reaches said one end of the first circumferential groove in communication with the upper end of the first axial groove, and when the shoe support further rotates on the corresponding wind pipe causing circumferential displacement of the first circumferential groove, the first protruding piece moves to lock at another end of the first circumferential groove, thereby achieving locking between the second connecting part and the first connecting part by rotation of the shoe support. 
     
     
         4 . The connecting structure of  claim 3 , wherein a limiting bar is arranged between two ends of the first circumferential groove; the limiting bar is transversely positioned in the first circumferential groove such that both upper and lower ends of the limiting bar are connected to upper and lower walls of the first circumferential groove; two first protruding pieces are provided; when the second connecting part is locked with the first connecting part, the two first protruding pieces are locked on two sides of the limiting bar respectively. 
     
     
         5 . The connecting structure of  claim 4 , wherein a distal end of at least one of the first protruding pieces is shaped as a rounded corner. 
     
     
         6 . The connecting structure of  claim 5 , wherein two sides of the limiting bar are provided with inclined guiding planes respectively to facilitate slidable movements of the first protruding piece. 
     
     
         7 . The connecting structure of  claim 3 , wherein the first axial groove and the first circumferential groove both penetrate through an outer side wall of the shoe support along a radial direction of the shoe support. 
     
     
         8 . The connecting structure of  claim 7 , wherein an upper wall of the first protruding piece is provided with a limiting protrusion, an upper wall of the first circumferential groove is provided with a first limiting groove corresponding to the limiting protrusion, and the limiting protrusion is removably inserted into the first limiting groove. 
     
     
         9 . The connecting structure of  claim 3 , wherein the connecting structure further comprises at least one extension pipe, wherein a lower end of each extension pipe is provided with a third connecting part having a same structure as the first connecting part, and an outer wall of an upper end of the extension pipe is provided with a fourth connecting part having a same structure as the second connecting part. 
     
     
         10 . The connecting structure of  claim 9 , wherein the third connecting part of each extension pipe comprises a second axial groove extending along an axial direction of the extension pipe, and a second circumferential groove disposed along a circumferential direction of the extension pipe, wherein a lower end of the second axial groove extends to a bottom end of the extension pipe, and one end of the second circumferential groove is in communication with an upper end of the second axial groove; the fourth connecting part comprises a second protruding piece provided on an outer wall of the extension pipe. 
     
     
         11 . The connecting structure of  claim 10 , wherein another end of the second circumferential groove of the third connecting part of each extension pipe is provided with a second limiting groove; the second connecting part of a corresponding wind pipe is removably inserted into the second limiting groove. 
     
     
         12 . The connecting structure of  claim 3 , wherein each shoe support comprises a supporting frame and a connecting pipe, wherein the supporting frame has a shoe support shape or a palm shape; a lower end of the connecting pipe is provided with the first connecting part. 
     
     
         13 . The connecting structure of  claim 12 , wherein an upper end of the connecting pipe is provided with a fifth connecting part; a lower end of the supporting frame is inserted into the upper end of the connecting pipe; an outer wall of the supporting frame is provided with a sixth connecting part locked with the fifth connecting part by circumferential displacement of the fifth connecting part; the supporting frame and the connecting pipe are locked with respect to each other through the fifth connecting part and the sixth connecting part by circumferential displacement of the fifth connecting part respect to the sixth connecting part so that the sixth connecting part is locked into the fifth connecting part. 
     
     
         14 . The connecting structure of  claim 13 , wherein the supporting frame is provided with slots that allow the upper end of a corresponding connecting pipe to be inserted into.
