Description

Technical Field

[0001] The utility model relates to the technical field of shoes and clothing, and particularly relates to a support type 3D printing insole. Background Art

[0002] An insole refers to a pad placed on the bottom surface of the inner cavity of a shoe to isolate the foot from the shoe. Its shape is usually the same as the bottom surface of the inner cavity of the shoe. Since a non-woven fabric insole cloth is generally laid on the upper surface of the midsole of the shoe and the surface of the insole cloth is relatively smooth, when the user's foot directly contacts the insole cloth, it is easy to cause a slipping phenomenon. After inserting the insole, the friction between the foot and the shoe can be increased through the insole, reducing the probability of slipping. At the same time, the insole can provide better shock absorption for the foot, making the wearing more comfortable.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: the existing insoles are usually made of EVA materials and need to be manufactured through multiple processes such as raw material foaming, shaping, cutting, and stacking. The manufacturing steps are numerous. The manufactured insoles have a high softness due to the characteristics of their materials, so they are easily deformed by depression after being stepped on, and have poor support for the foot, especially the arch position. When performing high-intensity exercises, it is easy to cause the foot to not obtain enough support and quickly fatigue. At the same time, after being stepped on for a period of time, the heel bears more weight and is easily collapsed, with poor durability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a support type 3D printing insole with fewer processing steps, good support, and strong durability in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: a support type 3D printing insole, including a 3D printing insole body and a strengthened stacking layer arranged at the position corresponding to the arch of the 3D printing insole body. The strengthened stacking layer protrudes upward in an arc shape and is the same as the arc of the human foot arch. The 3D printing insole body includes a low-density shoe pad layer corresponding to the front sole of the human foot and a high-density shoe pad layer corresponding to the heel of the human foot. The low-density shoe pad layer is composed of a number of elastic support blocks with deformation gaps between them, and the high-density shoe pad layer is composed of a number of elastic support blocks that are attached to each other.

[0006] Further improvement is that: a flannelette layer is provided on the top surface of the 3D printing insole body.

[0007] Further improvement is that: a number of silicone convex points are provided at the position corresponding to the front sole of the human foot on the top surface of the flannelette layer.

[0008] Further improvement: A heel surrounding layer with the same arc as the human foot heel is provided at the edge of the high-density shoe insole layer.

[0009] Further improvement: At the middle position of the bottom surface of the 3D printed insole body, a high-density torsion-resistant layer extending to the heel position of the 3D printed insole body is provided by 3D printing.

[0010] Further improvement: The torsion-resistant layer is in the shape of a shovel-shaped arc block.

[0011] Further improvement: A buffer block with an airbag structure is provided on the bottom surface of the 3D printed insole body at the position corresponding to the human foot heel.

[0012] Further improvement: The elastic support block includes a horizontally placed hollow tube and an X-shaped deformation frame arranged on the outer wall of the hollow tube, and a vertical support frame is provided at the end of the deformation frame.

[0013] Further improvement: An arc-shaped piece is provided on the side wall of the support frame.

[0014] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: The present utility model uses 3D printing technology to stack and print the high-density shoe insole layer and the low-density shoe insole layer at one time, which can be formed in one processing, with fewer processing steps. The reinforced stacking layer formed by 3D printing is used to support the arch position of the wearer's foot, avoiding rapid fatigue of the foot during exercise. At the same time, the high-density shoe insole layer and the low-density shoe insole layer can be formed in one processing. The low-density shoe insole layer is used to improve the foot feeling at the corresponding position of the forefoot of the foot, and the high-density shoe insole layer is used to improve the durability at the heel position, with higher durability and not easy to collapse.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Refer to Figures 1-5As shown in the figure, the technical solution adopted in this specific embodiment is as follows: A support-type 3D printed insole, including a 3D printed insole body 1 and a reinforced stacking layer 2 arranged at the position corresponding to the arch of the 3D printed insole body 1. The reinforced stacking layer 2 protrudes upward in an arc shape and has the same curvature as the human foot arch. The 3D printed insole body 1 includes a low-density insole layer 11 corresponding to the front sole of the human foot and a high-density insole layer 12 corresponding to the heel of the human foot. The low-density insole layer 11 is composed of a number of elastic support blocks 112 with deformation gaps 111 between them. The high-density insole layer 12 is composed of a number of elastic support blocks 112 that are in contact with each other. The elastic support block 112 includes a horizontally placed hollow tube 21 and an X-shaped deformation frame 22 arranged on the outer wall of the hollow tube 21. An upright support frame 23 is provided at the end of the deformation frame 22. When in use, the 3D printed insole body 1 is installed in the shoe, and the low-density insole layer 11 is placed at the front sole position of the shoe, and the high-density insole layer 12 is placed at the heel position of the shoe. When the user inserts the foot into the shoe and steps on the 3D printed insole body 1 with the sole of the foot, the front sole can step on the low-density insole layer 11. The low-density insole layer 11 is composed of elastic support blocks 112, and there is a deformation gap 111 between each elastic support block 112. When the front sole is pressed down and stepped on, the hollow tube 21 and the deformation frame 22 can simultaneously receive the pressure transmitted from the support frame 23, generate deformation, and deform to both sides, invading into the deformation gap 111, generating a large amount of deformation to absorb the pressure. Furthermore, the low-density insole layer 11 can provide sufficient deformation buffering ability for the front sole of the foot, greatly improving the shock absorption effect of the front sole and effectively improving the foot feeling. The heel of the foot will press on the high-density insole layer 12. Then, when walking, the heel is repeatedly squeezed by the heel of the foot. The high-density insole layer 12 is composed of elastic support blocks 112 that are in contact with each other. Then, when being squeezed, since the support frames 23 are in contact with each other, the space for the deformation frame 22 to deform is relatively small, and it is not easy to be overly deformed and unable to recover due to permanent deformation. After repeated stepping on, it can still maintain its shape and is not easy to collapse. At the same time, the arch position of the foot will be supported by the reinforced stacking layer 2 and is not in a suspended state, thereby avoiding rapid fatigue of the foot during exercise. At the same time, the entire 3D printed insole body 1 and the reinforced stacking layer 2 are both stacked and printed at one time according to different density requirements through 3D printing technology, and can be formed in one processing step with fewer processing steps;

[0023] A flannelette layer 4 is provided on the top surface of the 3D printed insole body 1, which is beneficial to improving the touch when the foot contacts the 3D printed insole body 1 through the flannelette layer 4, and at the same time increasing the friction coefficient to prevent slipping;

[0024] A number of silicone bumps 5 are provided on the top surface of the flannelette layer 4 at the position corresponding to the front sole of the human foot, which is beneficial to further increasing the friction between the foot and the insole and preventing slipping;

[0025] The edge of the high-density shoe insole layer 12 is provided with a heel surrounding layer 3 having the same arc as the human foot heel, which is beneficial to surround the foot heel, prevent the foot heel from moving during trampling and causing sprain, and has stronger use stability;

[0026] At the middle position of the bottom surface of the 3D printing insole body 1, a high-density torsion-resistant layer 14 extending to the heel position of the 3D printing insole body 1 is provided by 3D printing. The torsion-resistant layer 14 is in the shape of a shovel-shaped arc block, which is beneficial to improve the overall anti-twisting ability of the insole, avoid bending when receiving a lateral force, and prevent the user from spraining the foot;

[0027] A buffer block 13 with an airbag structure is provided on the bottom surface of the 3D printing insole body 1 at the position of the human foot heel, which is beneficial to improve the shock absorption limit of the heel and make the shock absorption performance better;

[0028] An arc-shaped piece 24 is provided on the side wall of the support frame 23, which is beneficial to improve the compressive performance of the support frame 23, so that it will not be immediately deformed excessively when receiving a high impact, and further improve its service life.

[0029] The working principle of the present utility model: When the present utility model is in use, the 3D printing insole body 1 is installed in the shoe, and the low-density shoe insole layer 11 is placed at the forefoot position of the shoe, and the high-density shoe insole layer 12 is placed at the heel position of the shoe. When the user inserts the foot into the shoe and steps on the 3D printing insole body 1 with the sole of the foot, the forefoot can step on the low-density shoe insole layer 11. The low-density shoe insole layer 11 is composed of elastic support blocks 112, and there is a deformation gap 111 between each elastic support block 112. When the forefoot is pressed down and stepped on, the hollow tube 21 and the deformation frame 22 can simultaneously receive the pressure transmitted from the support frame 23, generate deformation, and deform to both sides, invade into the deformation gap 111, and generate a large amount of deformation to absorb the pressure. Furthermore, the low-density shoe insole layer 11 can provide sufficient deformation buffer capacity for the forefoot of the foot, greatly improve the forefoot shock absorption effect, effectively improve the foot feeling, and the heel of the foot will press on the high-density shoe insole layer 12. Furthermore, during walking, the heel is repeatedly squeezed by the heel of the foot, and the high-density shoe insole layer 12 is composed of mutually attached elastic support blocks 112. Therefore, when being squeezed, due to the mutual attachment of the support frames 23, the deformation space of the deformation frame 22 is relatively small, and it is not easy to be deformed excessively and generate a permanent deformation that cannot be restored. After repeated trampling, it can still maintain its shape and is not easy to collapse. At the same time, the arch position of the foot will be supported by the strengthening stacking layer 2 and is not in a suspended state. Therefore, it is possible to avoid rapid fatigue of the foot during wearing and exercise. At the same time, the entire 3D printing insole body 1 and the strengthening stacking layer 2 are both stacked and printed according to different density requirements at one time by 3D printing technology, and can be formed in one processing, with fewer processing steps.
