Description

Technical Field

[0001] The utility model relates to the technical field of shoe expanders, in particular to a novel shoe expander. Background Art

[0002] When consumers wear newly purchased shoes, they often find that the shoe size is too small, or due to physiological reasons, some special parts of the shoes are squeezed, which brings great pain and trouble to the wearer. For this reason, people have invented shoe expanders to expand the shoes a little to make them suitable for wearing. The more commonly used shoe expanders currently consist of two V-shaped juxtaposed shoe last halves, a heel support, a last screw, a support screw sleeve, and a hemispherical wedge. Conical slideways are arranged inside the two shoe last halves, and the hemispherical wedges are fixed on the top of the last screw. By rotating the last screw, the hemispherical wedges are displaced on the conical slideway, thereby increasing the opening angle of the V-shaped juxtaposed shoe last halves, thereby achieving the purpose of expanding the shoe cavity.

[0003] However, the structure of the shoe expander using this design is not reasonable. In actual use, the two shoe last halves are spread out to both sides, and the last screw arranged in the middle hinders the spreading angle of the two shoe last halves, so the two shoe last halves of the existing shoe expander are not spread out at an adequate angle, causing inconvenience in use.

[0004] In addition, in the prior art, due to long-term use, the connection between the bottom of the two shoe last halves and the last body screw becomes loose, resulting in insufficient stability during use and dissatisfaction among consumers. Utility Model Content

[0005] The main purpose of the utility model is to provide a new shoe expander which has strong practicability, reasonable structure, diverse functions, more convenient and stable use and prolonged service life.

[0006] To achieve the above purpose, the utility model proposes a new shoe expander, including a shoe last, a heel support, a shoe last screw, and a support screw sleeve. A wedge is arranged in the shoe last, and a fixing seat is arranged on the shoe last screw, and the fixing seat is arranged at the bottom of the shoe last;

[0007] The shoe last body comprises a first shoe last half body and a second shoe last half body, the bottom of the first shoe last half body comprises a first end column and a second end column, the first end column and the second end column are arranged in parallel and spaced apart; the bottom of the second shoe last half body comprises a third end column and a fourth end column, the third end column and the fourth end column are arranged in parallel and spaced apart;

[0008] The fixing seat includes a convex groove, and the two sides of the convex groove respectively include a first groove and a second groove. The first end column and the second end column are arranged in the first groove, and the third end column and the fourth end column are arranged in the second groove.

[0009] Optionally, the last screw includes a transversely arranged cylindrical nut, and the fixed seat includes a left half fixed seat and a right half fixed seat, and the left half fixed seat and the right half fixed seat respectively include a left blind hole and a right blind hole; the two ends of the cylindrical nut are connected to the left half fixed seat and the right half fixed seat through the left blind hole and the right blind hole respectively.

[0010] Optionally, the fixing seat includes a first stud and a second stud, and the positions of the first stud and the second stud correspond to the positions of the first end column and the second end column, the third end column and the fourth end column respectively. The fixing seat is connected to the first end column and the second end column, the third end column and the fourth end column respectively through the first stud and the second stud.

[0011] Optionally, the first shoe last half and the second shoe last half are mirror-symmetrical structures, the first shoe last half includes a first oblique groove and a second oblique groove, the second shoe last half includes a third oblique groove and a fourth oblique groove, and the wedge slides along the first oblique groove and the second oblique groove, the third oblique groove and the fourth oblique groove respectively.

[0012] Optionally, the wedge is in an inverted trapezoidal shape, the top of the wedge includes a notch, and a through hole is arranged in the notch; the shapes of the two side edges of the wedge correspond to the shapes of the oblique grooves in the first shoe last half and the second shoe last half.
