TECHNICAL FIELD

[0001] The utility model relates to shoemaking technical field especially relates to a vamp elastic band strutting jig. BACKGROUND

[0002] Shoes are indispensable products in daily life, and some shoe types are elastic band shoes, which have elastic bands on the vamp. After the vamp and the sole are bonded, the insole needs to be inserted into the shoe. The current processing method is to manually turn the elastic band onto the sole and then insert the insole into the shoe. Since the elastic band needs to be turned over, and the shoe needs to be fixed by hand during the insole insertion process, the processing efficiency is slow. Therefore, a jig needs to be made to solve the above problems.

[0020] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Example 1

[0022] Reference Figures 1-4 A vamp elastic band stretching jig comprises a base plate 1, a fixing block 2 for fixing a toe cap, and an adjusting block 3 for adjusting the position of the fixing block 2. The base plate 1 is oppositely arranged with a pair of stretching frames 4. The opening formed by the pair of stretching frames 4 gradually increases. The adjusting block 3 is in sliding connection with the base plate and is located between the pair of stretching frames 4. The fixing block 2 is in sliding connection with the adjusting block 3.

[0023] In the embodiment, the specific use process of the vamp elastic band stretching jig is as follows: first, the vamp elastic band is inserted into the pair of stretching frames 4, and the distance between the pair of stretching frames 4 gradually decreases along the direction of inserting the shoe, so that the vamp elastic band near the shoe opening is stretched, and the vamp elastic band near the toe cap is stretched less, thereby preventing the vamp elastic band from being excessively stretched and damaged. Then, the toe cap is aligned with the fixing block 2, and the toe cap is fixed on the fixing block 2 to prevent the shoe from shaking when the insole is inserted. Finally, the insole is inserted into the shoe, and after the operation is completed, the shoe is removed, and the above operation is repeated.

[0024] It should be noted that the vamp elastic band is stretched by the stretching frames 4, which prevents the vamp elastic band from affecting the insertion of the insole into the shoe. In addition, the stretching frames and the fixing block 2 can jointly fix the shoe. The sliding connection between the adjusting block 3 and the base plate 1 and the sliding connection between the fixing block 2 and the adjusting block 3 can adapt to different specifications of shoes, improve the universality, and be conducive to reducing the cost.

[0025] Preferably, the adjusting block 3 is provided with a pair of first strip-shaped holes 31, the base plate 1 is provided with a plurality of pairs of first screw holes 11 matched with the first strip-shaped holes 31, and the base plate 1 is in sliding connection with the first strip-shaped holes 31 through the star-shaped hand screw 5.

[0026] In the embodiment, the adjusting block 3 is placed on the base plate 1, the spanner screw 5 is used to pass through a pair of first strip-shaped holes 31 of the adjusting block 3, and is fixed in a pair of first screw holes of the base plate 1. After the adjusting block 3 adjusts the distance, the spanner screw 5 is used for locking. When the length range of the first strip-shaped hole 31 does not meet the use requirement, the spanner screw 5 can be unscrewed, and then another pair of first screw holes 11 is used to increase the adjusting range of the adjusting block 3.

[0027] Preferably, the adjusting block 3 is provided with a first boss 32; the first boss 32 is provided with a pair of second strip-shaped holes 33; the fixing block 2 is provided with a second screw hole 21 matched with the second strip-shaped hole 33; and the fixing block 2 is slidably connected with the second strip-shaped hole 33 through the butterfly screw 6.

[0028] In the embodiment, the first boss 32 is used for placing the fixing block 2, so that the fixing block 2 can slide on the first boss 32, thereby adjusting the distance between the fixing block 2 and the base plate 1. By adjusting the distance between the fixing block 2 and the base plate 1, the toe of the shoe is clamped between the fixing block 2 and the base plate 1 to be fixed, thereby realizing the fixing of the shoe.

[0029] Preferably, the upper surface of the fixing block 2 is provided with a limiting frame 22 for fixing the toe; and the limiting frame 22 is in the shape of U.

[0030] In the embodiment, in order to further realize the fixing of the toe, the fixing block 2 is provided with the limiting frame 22. After the shoe is put into the opening and closing frame 4, the toe can be clamped in the limiting frame 22, so that the toe is fixed in the space formed by the limiting frame 22.

[0031] Preferably, the opening and closing frame 4 is sequentially connected by a first connecting rod 41, a second connecting rod 42 and a third connecting rod 43; the first connecting rod 41 is vertically fixed on the upper surface of the base plate 1; the second connecting rod 42 is parallel to the base plate 1; and the opening formed by the pair of third connecting rods 43 gradually increases.

[0032] In the embodiment, the opening and closing frame 4 is connected by the rod body. When the elastic band of the shoe is put into the opening and closing frame 4, the third connecting rod 43 will be slightly deformed, so that the elastic band can be easily put into the opening and closing frame 4. When the shoe is fixed on the jig, the elastic band of the toe does not need to be opened, but only needs to be opened at the shoe opening. Therefore, the opening formed by the pair of third connecting rods 43 gradually increases, which is convenient for inserting the midsole and will not damage the elastic band. When the shoe is taken out of the jig, the third connecting rod 43 will also be slightly deformed under the action of the elastic force of the elastic band, so that the opening formed by the pair of third connecting rods 43 will be slightly smaller, further preventing the damage of the elastic band.

[0033] Preferably, the opening frame 4 is made of stainless steel; the fixing block 2 is made of stainless steel.

[0034] In the embodiment, the opening frame 4 needs to be slightly deformed when the shoes are put in and taken out, and needs to have certain hardness to increase the service life. Therefore, stainless steel is used as the material of the opening frame 4 and the fixing block 2, which not only ensures the structural strength, but also has certain elasticity.

[0035] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
