Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to an adjustable protective children's shoe. Background Technology

[0002] Children's shoes (the age range of children is broad, generally between 0-16 years old). Children's shoes are specifically designed for this age group and are tailored to the growth and development characteristics of children's feet. They emphasize lightweight, breathability, comfort, and suitability for healthy foot growth.

[0003] While traditional children's shoes may be lightweight or breathable, the soles are usually made of materials such as PVC or PU. When children wear these shoes to run or jump, the heel area of ​​the sole is not well cushioned and protected. This makes it difficult to reduce the impact on the heel and knee joints during exercise, thus reducing the risk of sports injuries. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an adjustable protective children's shoe that can reduce the impact on the heel and knee joints during exercise and reduce the risk of sports injuries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable protective children's shoe, including a sole, an upper disposed on the sole, a tongue disposed on the upper, and a tension adjustment strap disposed on the upper, including a heel cushioning hole opened on the sole at the heel position, and a detachable protective cushioning block disposed on the sole within the heel cushioning hole, the heel cushioning hole being disposed through the front and rear sides of the sole, the protective cushioning block being disposed along the length direction of the heel cushioning hole, and the anti-slip cushioning block being fitted with the heel cushioning hole with a gap.

[0006] A further improvement is that a guide groove is provided on the sole of the shoe, and a guide block is provided on the protective buffer block, with the guide block and the guide groove fitting together with a clearance.

[0007] A further improvement is that the protective buffer block includes an elastic block and support plates fixedly disposed at the upper and lower ends of the elastic block.

[0008] A further improvement is that the elastic block has two deformation openings, which are symmetrically arranged.

[0009] A further improvement is that a waist-shaped support is provided on the elastic block within the deformation opening, and a pressing space is formed on the upper and lower sides of the waist-shaped support.

[0010] A further improvement is that the elastic block has concave and convex surfaces on its left and right sides.

[0011] A further improvement is that the concave and convex surfaces are either wavy or conical.

[0012] A further improvement is that the support plate is made of nylon or PVC.

[0013] A further improvement is that the waist-shaped support body has pressure-reducing openings.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When children wear children's shoes to run and jump, the heel of the sole impacts the ground. At this time, the heel cushioning hole is deformed and the reaction force of the contact with the ground is buffered, thereby reducing the impact force transmitted to the heel. In order to improve the support effect of the heel, a protective cushioning block can be installed in the heel cushioning hole. The anti-slip cushioning block can reduce the concave space of the heel cushioning hole, preventing excessive concavity from affecting the support effect of the heel. When it is necessary to increase the softness of the heel, the protective cushioning block can be removed from the heel cushioning hole. The softness and support of the heel can be adjusted according to the needs of use. The heel part of the sole can play a cushioning and protective role, reducing the impact on the heel and knee joint during exercise, thereby reducing the risk of sports injury.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 3 As shown, the technical solution adopted in this specific embodiment is: an adjustable protective children's shoe, including a sole 1, an upper 2 disposed on the sole 1, a tongue 3 disposed on the upper 2, and a tension adjustment strap 4 disposed on the upper 2. It includes a heel cushioning hole 5 opened on the sole 1 at the heel position, and a protective cushioning block 6 detachably disposed on the sole 1 within the heel cushioning hole 5. The number of protective cushioning blocks 6 can be one or two. When there are two, the two protective cushioning blocks 6 are symmetrically arranged. When there is one, the protective cushioning block 6 is installed in the middle position of the heel cushioning hole. The heel cushioning hole 5 is disposed through the front and rear sides of the sole 1. The protective cushioning block 6 is disposed along the length direction of the heel cushioning hole 5. The anti-slip cushioning block is in clearance fit with the heel cushioning hole 5. A guide groove 7 is opened on the sole 1, and a guide block 8 is disposed on the protective cushioning block 6. The guide block 8 is in clearance fit with the guide groove 7.

[0022] The protective buffer block 6 includes an elastic block 61 and support plates 62 fixedly disposed at the upper and lower ends of the elastic block 61. The support plates 62 are made of nylon or PVC. Nylon has good support properties, mainly reflected in its high strength, compressive strength, wear resistance, and temperature resistance. PVC material has good compressive strength and outstanding resistance to pressure and water pressure. For example, building water supply pipes can withstand large water pressure and are not easily deformed after long-term use. The protective buffer block 6 can also be made entirely of rubber elastomer. However, if a better support effect is required, the protective buffer block 6 can be made of materials with an elastic coefficient greater than that of rubber, such as nylon, PU, ​​or PVC. A guide block 8 is disposed on the lower end face of the support plate 62 located on the lower side. The guide block 8 is integrally formed or bonded to the support plate 62. The elastic block 61 is fixedly connected to the two support plates 62 by bonding or heat fusion.

[0023] Two deformation openings 63 are provided on the elastic block 61, and the two deformation openings 63 are symmetrically arranged. One end of the deformation opening 63 is an elliptical surface, and the other end is a concave arc surface.

[0024] An elongated support 64 is disposed on the elastic block 61 within the deformation opening 63. The elongated support 64 has a pressure-reducing opening 67, and pressure-sealing spaces 65 are formed on its upper and lower sides. When impact force is transmitted to the elongated support 64, the pressure-reducing opening 67 can relieve pressure, reducing the likelihood of breakage or vibration of the elongated support 64. The elongated support 64 is a nylon or PVC support and is installed in the deformation opening 63 by embedding or bonding.

[0025] The elastic block 61 has concave and convex surfaces 66 on its left and right sides.

[0026] The convex-concave side surface 66 is a wavy surface or a conical surface.

[0027] The working principle of this invention is as follows: When children wear children's shoes and engage in running or jumping, the heel of the sole 1 impacts the ground, generating a reaction force on the heel. The heel cushioning hole 5 increases the deformation space of the heel area of ​​the sole 1, thus reducing the impact force on the heel. The concave deformation of the heel cushioning hole 5 provides cushioning. The protective cushioning block 6, after being inserted into the heel cushioning hole 5, reduces the deformation space of the heel cushioning hole 5 but improves the support effect of the heel area of ​​the sole 1, preventing excessive concavity from reducing the support performance of the heel. The cushioning effect of the heel area can be adjusted as needed by installing and removing the protective cushioning block 6. When the protective cushioning block 6 is inserted into the heel cushioning hole 5, the guide block 8 is aligned with the guide groove 7, thus limiting the lateral movement of the protective cushioning block 6 when it is within the heel cushioning hole 5. To prevent the positional displacement of the protective buffer block 6 from affecting the uniformity of the heel buffer hole 5, when the heel buffer hole 5 is located within the heel buffer hole 5 and the heel of the sole 1 impacts the ground, the elastic block 61 can generate elastic deformation. The deformation space of the elastic block 61 is increased through the deformation opening 63, further providing a cushioning effect. The support plates 62 at the upper and lower ends provide support, reducing the occurrence of the elastic block 61 tilting due to force, and causing the elastic block 61 to deform in the longitudinal direction. The waist-shaped support body 64 can support the elastic block 61 in the deformation opening 63 when it is recessed, guiding the elastic block 61 to deform in the position of the compression space 65, thereby allowing the elastic block 61 to deform in the center. The longitudinal deformation effect of the elastic block 61 is improved through the side concave and convex surfaces 66. When the elastic block 61 loses the compressive force, the elastic block 61 releases its elastic potential energy to reset, so as to facilitate subsequent cushioning actions.
