Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-4, the utility model provides a last convenient to sole installation is dismantled, including last 1, bottom hole 2 has been seted up to the bottom heel department of last 1, the inside fixed of bottom hole 2 is inlayed and is equipped with first nut 3, the mounting hole 4 has been seted up on the top of stating last 1, the inside fixed of mounting hole 4 is inlayed and is equipped with second nut 5, the bottom laminating of last 1 has sole 7, sole 7 includes upper base 9 and insole 8, it is equipped with the heel EVA pad to press from both sides between upper base 9 and the insole 8, the trompil has all been seted up in the bottom heel department of heel EVA pad and insole 8, the root of upper base 9 turns over 180 backs, the heel EVA pad and the heel portion of insole 8 pass trompil and second nut 5 threaded connection through fastening screw 10.

Furthermore, the top end of the heel part of the last 1 is provided with a connecting hole 6, and a screw rod on the last frame can penetrate through the connecting hole 6 to quickly limit the last 1.

Further, the inside bottom of bottom hole 2 and the inside bottom of mounting hole 4 all are the hexagon, and first nut 3 and second nut 5 are hexagon nut for first nut 3 and second nut 5 can be respectively fixed imbed the inside bottom of bottom hole 2 and mounting hole 4, and when avoiding rotating fastening screw 10, rotation takes place for first nut 3 and second nut 5.

Furthermore, arrow-shaped metal anti-slip protrusions 11 are embedded in the bottom of the last 1, the metal anti-slip protrusions 11 can increase the contact friction force between the sole 7 and the bottom of the last 1, the sole 7 and the last 1 are prevented from shifting, meanwhile, the structural strength of the last bottom of the last 1 is increased, and serious abrasion caused by long-time use is avoided.

Further, sole 7 still includes through the shoes glue with 8 bottoms bonds the fixed lower bottoms in insole, goes to the bottom and can shelter from 8 trompils in insole to increase sole 7's bulk strength, make shoes more durable wear.

Specifically, when the shoe is produced, the second nut 5 in the connecting hole 6 at the top end of the last 1 is screwed with the bolt corresponding to the last frame, the last 1 is fixed, and the screw on the last frame penetrates through the connecting hole 6 to limit the last 1, so that the shoe tree is installed.

Subsequently, the sole 7 which is punched in the insole 8 and the heel EVA pad in the production process is placed on the last 1 and is aligned with the last 1, then the heel part of the upper sole 9 is pulled up and folded upwards by 180 degrees, a fastening screw 10 penetrates through the heel EVA pad and the opening of the heel part of the insole 8 to be fixed with the first nut 3 of the heel part of the last 1, the insole 8, the upper sole 9 and the shoe tree are fixed, then a worker can quickly fix (sew and fix or bond and fix) the upper and the insole 8 of the sole 7, the arrow-shaped metal anti-slip bulge 11 can increase the friction force between the sole 7 and the last 1, the sole 7 and the last 1 are prevented from shifting, meanwhile, the last structure strength of the last 1 is increased, and serious abrasion caused by long-time use is avoided.

When demolising, reverse fastening screw 10, make fastening screw 10 and 3 separations of first nut, can part shoe tree and sole 7 fast, lay flat upper end 9 again, and fill in size assorted EVA filler in the trompil, cover the trompil of heel EVA pad well end 8, make the hole site stealthy, reach pleasing to the eye effect, and it is fixed to utilize the shoe glue to bond upper end 9 and lower and insole 8, it also can shelter from insole 8's trompil to go to the bottom, and increase sole 7's bulk strength, make shoes more durable wear.

It should be added that: the arrowhead-shaped metal anti-slip bulge 11 is embedded in an arrowhead-shaped groove formed in the bottom of the last 1 and is 0.5-1mm higher than the arrowhead-shaped groove, so that the friction limiting effect on the sole 7 and the last 1 can be effectively achieved, and the damage to the upper bottom 9 of the sole 7 caused by the fact that the metal anti-slip bulge 11 excessively props against the sole 7 is also avoided.
