Description

Technical Field

[0001] The utility model belongs to the technical field of shoemaking and relates to a supporting tool, in particular to a supporting tool for upper stretching. Background Art

[0002] The ribs are protruding from the sole, and a circle is set at the edge of the sole to fix the insole. When the upper is stretched, the upper is fixed on the sole and close to the outer wall of the ribs, but the ribs are relatively soft and independently ribbed, without any support inside or outside. When the upper is stretched, the ribs will tilt inward and collapse under the strong pressure of the upper. However, the upper needs to fit closely with the ribs, and the ribs tilt inward, causing the upper to tilt inward as well, which finally causes uneven stretching of the upper and the sole, affecting the quality of the finished shoes. Utility Model Content

[0003] In order to solve the above deficiencies in the prior art, the utility model aims to provide a supporting tool for the upper part, so as to prevent the ribs from tilting inwards when the upper part is stretched and improve the flatness of the upper part.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A support tool for shoe uppers comprises a forefoot piece, a heel piece plugged into the forefoot piece and a length regulating device for controlling the plugging position of the heel piece; a slot is provided on the end surface of the forefoot piece, a spring is fixed in the slot, the heel piece is plugged into the slot of the forefoot piece and combined with the forefoot piece to form a sole shape, and one end of the heel piece plugged into the slot is fixedly connected to the other end of the spring.

[0006] As a limitation of the present invention, the length adjustment device includes a first control rod with one end hinged on the front palm piece and a second control rod with one end hinged on the heel piece, the other end of the first control rod and the other end of the second control rod are hinged together, and the opening angle of the first control rod and the second control rod is controlled by a bolt at the mutual hinge point.

[0007] As a further limitation of the present invention, a handle for hand-holding is fixedly provided on the first control rod or the second control rod.

[0008] As another limitation of the present invention, the edges of the front palm piece and the heel piece are both provided with rounded corners.

[0009] As a limitation of the present invention, the forefoot piece and the heel piece are both made of nylon or acrylic.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0011] (1) The utility model places the forefoot piece and the heel piece, which are in the same shape as the sole after assembly, inside the corrugated strips, and closely adheres to the inner edge of the corrugated strips to support the corrugated strips. Even if the pressure generated by the upper is too large and the force is transmitted to the edges of the forefoot piece and the heel piece, the corrugated strips will not tilt inward and collapse, which is conducive to fixing the upper surface along the track of the original corrugated strips, overcoming the defects of uneven upper or uneven sole. At the same time, under the action of the length control device, the heel piece can adjust the length of the forefoot piece to adapt to different shoe lengths, and has good versatility.

[0012] (2) The utility model uses two hinged first control rods and second control rods to control the length, which has a simple structure, high adjustment accuracy, convenient operation and easy control;

[0013] (3) The handle of the utility model is easy to hold and more convenient to use;

[0014] (4) The rounded corners of the utility model combined with nylon or acrylic materials can minimize damage to the ribs and provide better results.

[0015] In summary, the utility model can support the strips, overcome the defect of uneven uppers, and is suitable for shoemaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-Figure 3 As shown, this embodiment includes a forefoot piece 1, a heel piece 2 and a length adjustment device 4. The heel piece 2 is inserted into the forefoot piece 1 to form a whole sole 9. The support tool is placed on the sole 9 so that the edge of the support tool is against the inner wall of the rib 7. When the upper is stretched, the support tool of this embodiment supports the rib 7 to prevent the upper from being uneven. The length adjustment device 4 is used to adjust the length of the insertion between the forefoot piece 1 and the heel piece 2, and is used to adapt to different shoe sizes and adjust the length according to the shoe size.

[0025] The shape of the forefoot piece 1 is the shape of the forefoot of the sole 9, and a slot 11 is provided on its cross section. The material of the forefoot piece 1 is nylon or acrylic, and the material of the present embodiment is nylon. In order to smoothly insert the heel piece 2 into the slot 11, one side of the slot 11 is a separate structure from the forefoot piece 1, that is, it is concave downward along the upper surface of the forefoot piece 1 to form a groove, and then a baffle 12 is glued to the groove to form a slot 11 that is concave inward along the end surface of the forefoot piece 1. A plurality of springs 3 are fixedly provided in the slot 11 along the length direction of the forefoot piece 1 to prevent the heel piece 2 from being separated from the forefoot piece 1. The edges of the forefoot piece 1 are all provided with rounded corners to prevent the ribs 7 of the sole 9 from being scratched.

[0026] The shape of the heel piece 2 is the shape of the heel of the sole 9. The heel piece 2 is inserted into the slot 11 of the forefoot piece 1, and one end of the heel piece 2 inserted into the slot 11 is fixedly connected to the other end of the spring 3.
