Detailed Description

The drawings show the technical scheme and the embodiment of the invention, and the details and the working principle of the embodiment are further described in the following with the drawings.

Referring to fig. 1, 2 and 3, a sole according to a first embodiment of the present invention comprises a midsole 1, a sole 2, a steel hook core 3 and a heel 4, wherein the steel hook core 3 is fixed in the midsole 1, the sole 2 is fixed on the lower surface of the midsole 1, at least one connecting post 5 is provided on one side of the heel 4 facing the midsole, the connecting post 5 and the heel 4 are integrally formed, the number of the connecting post 5 can be one or two or three or four, a midsole through hole 6 and a hook core through hole 7 corresponding to the connecting post are provided at the rear root of the midsole and the steel hook core, the number, shape and position of the midsole through hole 6 and the hook core through hole 7 are adapted to the connecting post 5, a threaded hole 8 is provided in the middle of the connecting post 5, the connecting post 5 sequentially passes through the midsole through hole 6 and the hook core through hole 7 and is screwed in the threaded hole 8 by a screw 9, the diameter of the lower surface of the screw head of the screw 9 is larger than that of the hook center through hole 7, when the screw 9 is in threaded connection with the threaded hole 8, the lower surface of the screw head supports against the outer surface of the hook center through hole 7 or the outer surface of the middle sole through hole, the heel 4, the insole 1 and the steel hook center 3 are fixedly connected through screws in a tight manner, in the assembling process, a worker can accurately position the fixed positions of the insole 1 and the heel 4 by sleeving the connecting column 5 with the insole through hole 6 and the hook center through hole 7, the working time is greatly reduced, the working efficiency is improved, trouble and labor are saved, the insole 1 and the heel 4 are prevented from shifting in the screw nailing process, the screw 9 is in threaded connection with the threaded hole 8, the screw 9 is prevented from shifting askew in the heel fixing process, the working efficiency is improved, the insole through hole 6 and the hook center through hole 7 are sleeved on the connecting column 5 and are fixedly connected, the connection among the sole 1, the heel 4 and the steel hook core 3 is firmer and tighter, and the heel is prevented from falling off in use.

The transverse section of spliced pole 5 is circular, insole through-hole 6 and hook heart through-hole 7 are the circular through-hole with spliced pole 5 looks adaptation, when spliced pole 5's quantity is four, the quantity of insole through-hole 6 also is four, and four two liang of correspondences of circular spliced pole set up and are the square distribution, hook heart through-hole 7 includes four circular trompils 10, two liang of correspondences of circular trompil 10 distribute, be provided with bar hole 11 between two trompils 10 of adjacent correspondence, bar hole 11 cross section is less than the diameter of circular trompil, switches on through bar hole 11 between two trompils 10 of adjacent correspondence, forms a dysmorphism trompil, during production, need not to open quartic hole on the steel hook heart, only need carry on twice trompil can, practiced thrift the operating time of trompil, improved work efficiency greatly.
