Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole suitable for long-term standing. Background Art

[0002] Some professions such as teachers require long-term standing, which can easily lead to chronic injuries of the bones and joints of the lower limbs. This is mostly caused by changes in the biomechanical lines of the lower limbs, which lead to abnormal stress on the bones and joints. This is largely related to the unreasonable design of the soles of the shoes that people wear when walking naturally. Usually the insoles are flat, while the soles of the feet have a certain curvature, which will lead to uneven stress on the soles of the feet, imbalance of the femoral heads of the two legs, and then pelvic tilt, causing lumbar pain and many other problems. In addition, because the soles of the shoes do not fit the soles of the feet, the soles of the feet will slide in the shoes when walking, increasing the resistance to movement. Over time, they will cause soreness and fatigue, especially for people who stand or walk for a long time, which will cause certain injuries and lead to diseases.

[0003] The soles of existing shoes cannot provide relatively close support for people who stand for a long time, which makes the feet sore after standing for a long time and causes joint damage. Utility Model Content

[0004] In view of the above problems, the utility model aims to solve the above problems. One purpose of the utility model is to provide a sole suitable for long-term standing to solve the above problems.

[0005] The solution adopted in this embodiment is: a sole suitable for long-term standing, including a midsole and an insole, the midsole and the insole are adapted to each other; the midsole is provided with a receiving groove at the heel and the arch of the foot, an elastic capsule is provided in the receiving groove, the insole is located above the midsole, the insole is provided with a downwardly protruding extrusion portion at the heel position, and the insole is provided with an upwardly recessed supporting portion at the arch position; when standing, the extrusion portion squeezes the elastic capsule to move toward the supporting portion.

[0006] The specific structure of the receiving groove is that the receiving groove is provided with a sunken part at the heel position, the receiving groove is provided with a supporting part at the arch position, and an upwardly protruding partition is provided between the sunken part and the supporting part.

[0007] In order to better restrict the deformation of the elastic bladder, a suture line is provided in a ring shape in the middle of the elastic bladder, and the suture line is located at the partition.

[0008] Furthermore, the elastic bladder is filled with air or non-Newtonian fluid.

[0009] Preferably, the depth of the sunken part is greater than the depth of the supporting part, the sunken part and the supporting part are both arranged in an arc shape, and the depth of the sunken part and the supporting part gradually decreases from the center to both sides. The part of the elastic capsule located in the sunken part is arranged in a conical shape, and the part of the elastic capsule located in the supporting part is arranged relatively flat.

[0010] Preferably, a forefoot portion is provided at the front end of the midsole, the toes of the forefoot portion are tilted upward, and an extension portion adapted to the forefoot portion is provided at the front end of the insole.

[0011] The shoe sole suitable for long-term standing of the utility model has the following technical effects:

[0012] 1. The present application discloses a shoe sole suitable for long-term standing, comprising a midsole and an insole, wherein the midsole and the insole are adapted to each other; the midsole is provided with a receiving groove at the heel and the arch of the foot, an elastic capsule is provided in the receiving groove, and the insole is located above the midsole. Through the combined effect of the elastic capsule, the midsole and the insole, the support for the sole of the foot is more fitted and the sole is more elastic.

[0013] 2. The insole is provided with a downwardly protruding squeezing portion at the heel position, and an upwardly concave supporting portion at the arch position; when standing, the squeezing portion squeezes the elastic capsule to move toward the supporting portion. The special structural design of the insole enables the elastic capsule to provide a very tight support to the insole after deformation, thereby increasing the supporting surface of the insole on the sole of the foot, making the sole of the foot more evenly stressed, and avoiding concentrated stress that causes foot damage.

[0020] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0021] The shoe sole suitable for long-term standing is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, the utility model provides a sole suitable for long-term standing, comprising a midsole 1 and an insole 2, wherein the midsole 1 and the insole 2 are adapted to each other; the midsole 1 is provided with a receiving groove at the heel and arch of the foot, wherein an elastic capsule 3 is provided in the receiving groove, and the insole 2 is located above the midsole 1, wherein the insole 2 is provided with a downwardly protruding extrusion portion 21 at the heel, and the insole 2 is provided with an upwardly concave support portion 22 at the arch of the foot; when standing, the extrusion portion 21 squeezes the elastic capsule 3 to move toward the support portion 22. The heel acts on the extrusion portion 21 of the insole 2, and most of the human body's weight is concentrated on the extrusion portion 21, so that an extrusion force is formed on the elastic capsule 3, and the elastic capsule 3 of this part flows toward the support portion 22, so that the elastic capsule 3 forms a certain support force on the support portion 22, so that the support portion 22 can effectively support the arch of the foot and relieve the pressure on the heel.

[0023] The specific structure of the receiving groove is that the receiving groove is provided with a sunken portion 12 at the heel position, the receiving groove is provided with a supporting portion 14 at the arch position, and an upwardly protruding partition 13 is provided between the sunken portion 12 and the supporting portion 14. The receiving groove is divided into three parts, and the sunken portion 12 is used to accommodate the heel, so that the heel has a larger deformation space when squeezing the elastic capsule 3. The partition 13 protrudes upward to reduce the distance between the bottom of the receiving groove and the insole 2, so that the elastic capsule 3 is blocked from extending at this position, so that the deformation space is moved to the supporting portion 14, so that the elastic capsule 3 of the supporting portion 14 can swell higher and better fit and support the arch.

[0024] In order to better restrain the deformation of the elastic capsule 3, a suture 31 is provided in the middle of the elastic capsule 3 in an annular shape, and the suture 31 is located at the partition 13. The suture 31 is distributed at the partition 13, so that the elastic-plasticity of the elastic capsule 3 at this position is reduced. When the elastic capsule 3 at the position of the sunken part 12 is squeezed, the partition 13 will not expand and deform, and the deformation is concentrated on the supporting part 14. Furthermore, the elastic capsule 3 is filled with air or a non-Newtonian fluid. In this embodiment, non-Newtonian fluid is used as an example, and a rubber solution can be filled, and magnetic slurry can be doped at the same time, so that the non-Newtonian fluid also has a certain magnetism. The non-Newtonian fluid can make the elastic capsule 3 deform at a relatively slow speed, so that it will not deform rapidly and repeatedly when walking, and the deformation amplitude is reduced, so as to avoid the feeling of stepping on air caused by insufficient support of the sole. Filling with air makes the sole softer.

[0025] Preferably, the depth of the sunken portion 12 is greater than the depth of the supporting portion 14, and both the sunken portion 12 and the supporting portion 14 are arranged in an arc shape, and the depths of the sunken portion 12 and the supporting portion 14 gradually decrease from the center to both sides. Figure 2 In the top view of the elastic bladder 3 shown, the part of the elastic bladder 3 located at the sunken part 12 is conical, while the part of the elastic bladder 3 located at the supporting part 14 is relatively flat, so that the heel can be wrapped around, and the arch of the foot receives a curved support, and the overall support surface fits the sole of the foot to a large extent.

[0026] Preferably, the front end of the midsole 1 is provided with a forefoot portion 11, the toe position of the forefoot portion 11 is tilted upward, and the front end of the insole 2 is provided with an extension portion 23 adapted to the forefoot portion 11. The raised forefoot allows the heel to better fit the sole.
