Description

Technical Field

[0001] This utility model relates to the field of shoe processing technology, specifically to an auxiliary tool for inserting the heel webbing of a shoe into a slot. Background Technology

[0002] Currently, in shoe production, the upper is typically sewn first, and then glued or stitched to the sole. Since the sole usually has an edge that aligns with the upper, the entire sole has a groove-like structure, facilitating the application of glue or stitching for later fixation. However, in actual manufacturing, to maintain a tight fit between the sole and upper, and considering that the upper is not yet fully set, the toe is usually aligned first when fastening or gluing the upper and sole together, followed by the heel. The heel is relatively difficult to fit into the grooves on the sole. This is especially true since the heel usually has webbing, making it even harder to secure the webbing to the sole.

[0003] To address the aforementioned issues, workers typically use small tools such as inserters to guide the heel of the upper into the heel of the sole. However, these inserters are relatively simple in structure. While they solve the problem of guiding the heel of the upper into the heel of the sole, they are inconvenient to use. Furthermore, the inserter needs to guide the contact surfaces between the upper and sole during assembly to prevent folding of the bonding surface or webbing on the upper, which could affect the contact or adhesion between the upper and sole. Moreover, the current structure of the inserter makes it difficult to hold, and the sharp edges can easily injure the user's hands. Utility Model Content

[0004] In order to overcome one of the shortcomings of the prior art, the purpose of this utility model is to provide an auxiliary tool for inserting the heel webbing of a shoe into a slot. This auxiliary tool for inserting the heel webbing of a shoe into a slot has a simple structure and makes it easy to insert the heel webbing of the shoe into the sole.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] An auxiliary tool for inserting shoe heel webbing into a slot includes a main body and a grip sleeve disposed on the main body. One end of the main body extends outward and is provided with an insertion head. A curved portion is provided between the insertion head and the main body. The curved portion protrudes on one side of the main body. One end of the insertion head curves outward along the same side of the curved portion. Both sides of the insertion head are provided with rounded edges.

[0007] Furthermore, the bending radius of one end of the bent portion is greater than the bending radius of the other end.

[0008] Furthermore, the insertion head is a pointed tip, and the two sides of the insertion head smoothly transition to the end.

[0009] Furthermore, each of the curved portions has a notch on at least one side of the main body piece in the width direction, and the notch is smoothly connected to the curved portion.

[0010] Furthermore, the insertion head is deformable and repositionable.

[0011] Furthermore, the grip sleeve has a raised section in the middle, and the grip sleeve has recessed rings at both ends of the raised section.

[0012] Furthermore, the grip sleeve has a limiting ring at one end near the insertion head, and the side of the limiting ring on the corresponding side smoothly transitions with the concave ring portion.

[0013] Furthermore, the grip sleeve is provided with spotlight beads on both sides of the main body piece, and a storage battery is provided inside the grip sleeve to provide power to the spotlight beads. A push switch is provided on the grip sleeve to switch the storage battery and the spotlight beads on and off.

[0014] Furthermore, the grip sleeve is provided with a charging port that communicates with the battery.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] Reference Figures 1 to 3 The illustrated auxiliary tool for inserting shoe heel webbing into a slot includes a main body 10 and a grip sleeve 20 disposed on the main body 10. One end of the main body 10 extends outward and is provided with an insertion head 11. A curved portion 12 is provided between the insertion head 11 and the main body 10. The curved portion 12 protrudes on one side relative to the main body 10. One outward end of the insertion head 11 curves up along the same side as the curved portion 12. Both sides of the insertion head 11 are provided with smooth edges.

[0023] The main body 10 is a long strip structure, while the insertion head 11 is a pointed structure, which facilitates its insertion between the shoe upper and the sole. It has a certain degree of flexibility to adapt to the curvature of the shoe upper and improve the compatibility between the two. The bending radius of the bending part 12 is designed according to actual usage requirements. The purpose of this design is to adapt to the beveled structure of different soles, which improves the applicability of the product.

[0024] This auxiliary tool for inserting shoe heel webbing into a slot is designed with a main body 10 and a grip sleeve 20, facilitating easy handling and improving operational comfort. Furthermore, the insertion head 11 facilitates guiding the webbing from the shoe upper to the sole, and its structure allows for smooth insertion, making it easy for the upper to snap into the sole. The curved section 12 effectively adapts to the shoe edge, allowing the operator to secure the tool by snapping it into the edge. This design ensures consistent insertion depth and smoothness during the process of guiding the upper and sole into contact.

[0025] In practical use, most workers operate the tool with their right hand while using their left hand to press the upper and sole together. Therefore, when guiding the connection between the upper and sole, a clockwise operation is generally performed. In one embodiment of this application, the bending radius of one end of the curved portion 12 is larger than that of the other end. This design utilizes the guiding structure formed by the bending radii at both ends of the curved portion 12 to adapt to the worker's hand movements, increasing the smoothness of the guiding action. Furthermore, during actual operation, when the worker is actually guiding the contact surface between the upper and sole, the entire tool is not perpendicular to the gap between them; it generally has a certain angle of inclination. Therefore, the main body 10 will be tilted at a certain angle relative to the gap. Thus, during use, the end of the curved portion 12 with the larger bending radius is used as the side facing forward, which better adapts to the worker's guiding action.

[0026] See Figure 2 In one improved embodiment of this application, to facilitate better operation of the entire insertion head 11 when guiding the upper and sole of the shoe, and to avoid the bending portion 12 being too large and hindering the guiding action, a notch 13 is provided on at least one side of the bending portion 12 in the width direction of the main body piece 10, and the notch 13 is smoothly connected to the bending portion 12. Since the structure of the bending portion 12 itself makes it difficult to twist and deform, in this application, the depth of the notch 13 is between one-fifth and one-quarter of the width of the entire bending portion 12. This design allows the insertion head 11 to twist relative to the entire main body piece 10 during the subsequent deformation process, adapting to the gap between the upper and sole, and also better securing and straightening the webbing on the upper, ensuring the flatness of the bottom of the upper and the adhesion between it and the sole.

[0027] In the aforementioned practical application, to facilitate insertion into the gap between the shoe upper and sole, the insertion head 11 is designed with a pointed tip, and the two sides and ends of the insertion head 11 smoothly transition to each other. This makes the insertion head 11 a smooth insertion tip, making it easy for workers to insert into the gap between the shoe upper and sole. Furthermore, in one embodiment, to adapt to the gap structure between the shoe upper and sole, the insertion head 11 is deformable and can return to its original position. In fact, the insertion head 11 can be made of a commonly used elastic steel sheet. This structural design gives the insertion head 11 sufficient flexibility and elasticity to adapt to different usage situations.

[0028] See Figures 1 to 3In one embodiment of this application, for ease of gripping, the grip sleeve 20 has a raised portion 21 in the middle, and both ends of the grip sleeve 20 are provided with recessed ring portions 22. In actual use, the rear recessed ring portion 22 can be positioned directly opposite the user's thumb and forefinger, while the front recessed ring portion 22 is held between the user's index finger and thumb. The raised portion 21 is positioned precisely in the area between the user's thumb and forefinger and fingers. This design improves the user's operating comfort.

[0029] In the above-described improvement, to facilitate the operator's fingers sliding out of the concave ring 22 at the front end during insertion, the grip sleeve 20 is provided with a limiting ring 23 at one end near the insertion head 11. The side of the limiting ring 23 smoothly transitions to the concave ring 22. In fact, the concave ring 22 at the front end is provided with several anti-slip stripes.

[0030] See Figure 3 In one embodiment of this application, to facilitate the operator's visibility of the operating area when guiding the shoe upper and sole and inserting the webbing, the grip sleeve 20 is equipped with spotlight beads 24 on both sides of the main body piece 10. A battery is housed within the grip sleeve 20 to provide power to the spotlight beads 24. A push-button switch is provided on the grip sleeve 20 to switch the battery and spotlight beads 24 on and off. In some embodiments, however, the grip sleeve 20 does not contain a battery; instead, it is directly connected to the outside via a wire. This allows the wire to both provide power and act as a restraining rope, preventing the entire tool from falling.

[0031] In the above embodiments, in order to facilitate charging of the battery, the grip sleeve 20 is provided with a charging port 25 that communicates with the battery. Of course, in some embodiments, a wireless charging structure can also be provided, which can be used according to actual usage needs.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
