Description

Technical Field

[0001] The utility model relates to the technical field of shoe lasts, in particular to a modular combined shoe last. Background Art

[0002] Combined shoe last is an innovative shoe last design method, which divides the shoe last into multiple modules and combines these modules together through specific fixtures to achieve more flexible and efficient shoe last production and management.

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0004] The modules of the current combined shoe lasts are usually connected by wedge-shaped locking devices and screws. The design of these fixing devices allows the modules to be easily assembled and disassembled, but in actual applications, most of them can only adjust the front and rear distances, the adjustment degree is limited, and the flexibility of use is poor.

[0005] Therefore, the above technical problems need to be solved. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model proposes a modular combined shoe last, which solves the problem that most modules of the current combined shoe last can only be adjusted for front and rear distances, the adjustment degree is limited, and the flexibility of use is poor.

[0007] In order to solve the above technical problems, the basic technical solution proposed by the utility model is:

[0008] A modular combined shoe last comprises a front body of the last, a rear body of the last, and a mounting frame for connecting the two.

[0009] The front part of the shoe last is composed of a first toe part and a second toe part distributed on the left and right sides, and the back part of the shoe last is composed of a first heel part and a second heel part distributed on the left and right sides.

[0010] The mounting frame includes a support plate, on which two slide seats are slidably mounted and are both arranged perpendicular to the support plate, and the two slide seats are both locked and connected to the support plate via a first screw, and two assembly parts are slidably mounted on the slide seat, and the two assembly parts are both locked and connected to the slide seat via a second screw.

[0011] Preferably, the outer side of the top of the assembly part is provided with a flap extending vertically upward, and the outer side of the flap is provided with a protrusion, and the first toe part, the second toe part, the first heel part and the second heel part are provided with a positioning groove matched with the protrusion. The outer side of the flap is in contact with the first toe part, the second toe part, the first heel part and the second heel part, and preferably, the mutually matched protrusions and positioning grooves are provided to help the four assembly parts to be positioned and connected with the first toe part, the second toe part, the first heel part and the second heel part respectively.

[0012] Preferably, it also includes four long screws respectively penetrating the four assembly parts, and the four long screws respectively extend into the first toe part, the second toe part, the first heel part and the second heel part. The four assembly parts are used as connectors to realize the connection of the first toe part, the second toe part, the first heel part and the second heel part to the mounting frame respectively. Preferably, the long screws are used to ensure that the four assembly parts are respectively connected to the first toe part, the second toe part, the first heel part and the second heel part.

[0013] Preferably, the inner sides of the bottoms of the first toe portion, the second toe portion, the first heel portion, and the second heel portion are all provided with half grooves distributed along the length direction of the support plate. The mounting frame is set at the bottom between the front body of the shoe last and the back body of the shoe last. After the first toe portion and the second toe portion are assembled, the distance between the two half grooves is the smallest, and the distance is matched with the width of the support plate. Similarly, after the first heel portion and the second heel portion are assembled, the distance between the two half grooves is the smallest, and the distance is matched with the width of the support plate. That is, the bottoms of the front body of the shoe last and the back body of the shoe last are both provided with spaces for the support plate to move through, so as to facilitate length adjustment.

[0014] Preferably, the top of the front of the first heel part and the second heel part are both provided with a U-shaped groove, wherein the design of the U-shaped groove provides structural support for the operator's hand grip, and is helpful for the lifting action of the last in the subsequent disassembly operation.

[0015] The beneficial effects of the utility model are:

[0016] The technical solution of the present invention is to split the shoe last into four modules, namely, a first toe portion, a second toe portion, a first heel portion, and a second heel portion, and connect the four modules with the help of a mounting frame. In combination with a sliding seat slidably connected to a support plate and an assembly part slidably connected to the sliding seat, the planar layout of the four modules can be flexibly adjusted. Compared with the traditional module connection structure, the adjustable range and flexibility of use are improved. BRIEF DESCRIPTION OF THE DRAWINGS
