Description

Technical Field

[0001] The utility model relates to the technical field of insoles, in particular to a corrective insole. Background Art

[0002] The arch of the foot is an important structure of the human foot. It is an arch convex upwards, formed by the arched masonry of the tarsal bones and metatarsal bones, as well as the ligaments and tendons of the sole of the foot, which have elasticity and contraction force. It can be divided into longitudinal arches (medial longitudinal arch, lateral longitudinal arch and transverse arch). The medial longitudinal arch is located at the medial edge of the foot, and is composed of the calcaneus, talus, navicular bone, 3 cuneiform bones and the medial 1st to 3rd metatarsal bones. The highest point of the arch is the head of the talus. The lateral longitudinal arch is located at the lateral edge of the foot, and is composed of the calcaneus, cuboid bone and the 4th and 5th metatarsal bones. The cuboid bone is the highest point of the arch. The transverse arch is composed of the posterior part of each metatarsal bone and the anterior part of the tarsal bone, with the 2nd cuneiform bone being the highest. The main function of the arch is to disperse gravity from the ankle joint through the talus to the metatarsal head, and then to the calcaneus to ensure the stability of the plantar support when standing upright. The arch of the foot makes the human foot flexible, which can not only cushion the impact of the ground on the foot, but also lock the foot joints, making the foot firm and better promoting human activities;

[0003] Flat feet is a foot deformity characterized by severe collapse of the arch of the foot accompanied by calcaneal valgus and talar introversion. It may lead to Achilles tendon contracture, midfoot relaxation, forefoot displacement and increased pressure on the posterior tibial tendon, making posterior tibial tendon strain prone to occur. Severe flat feet may also cause fasciitis, tenosynovitis, compression of the plantar nerves and blood vessels, etc., so timely correction or treatment is required.

[0004] Currently, when using insoles to correct flat feet, since the correction pads are rigid and fixed in height, the correction degree on the soles of the patients' feet is relatively large at the beginning, which will cause discomfort to the patients. Especially when the intensity of exercise is high, the impact on the soles of the patients' feet will become greater, thereby causing damage to the soles of the patients' feet.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a corrective insole.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0008] A corrective insole comprises an insole body, a corrective block is fixed to the top of the insole body near one side edge, an expandable silica gel is arranged at the top of the corrective block near the inner side edge, and an expandable air bag is arranged inside the corrective block below the expandable silica gel;

[0009] An air inlet pipe is arranged on one side of the correction block, and the air inlet pipe is connected to the inside of the expansion air bag. A plurality of anti-skid patterns are fixed at equal intervals on the bottom of the insole body.

[0010] Optionally, a support ring is fixed between the inner walls of the air inlet pipe near one side edge, and an annular ring is fixed between the inner walls of the air inlet pipe near the other side edge.

[0011] Optionally, a guide rod is slidably connected between the inner walls of the annular ring, a conical block is fixed to one end of the guide rod, and a conical surface of the conical block is sealed and fitted with one side of the support ring.

[0012] Optionally, one side of the annular ring is provided with a plurality of through openings extending to the other side at equal intervals along the circumferential direction, and a spring is fixed to one side of the conical block.

[0013] Optionally, one end of the spring is fixed to one side of the annular ring, and an adjustment groove is provided at the bottom of the insole body.

[0014] Optionally, an adjusting column is threadedly connected between the inner walls of the adjusting groove, and a sealing rod is fixed to the top of the adjusting column.

[0015] Optionally, the top of the sealing rod slides through the interior of the inflatable airbag, and a plurality of air holes are equidistantly formed on the outer surface of the sealing rod near the top edge and penetrate to the bottom of the sealing rod.

[0016] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0017] 1. In the utility model, a correction block is arranged on the top of the insole body, and then an expansion air bag is arranged inside the correction block, and an expansion silica gel is arranged near the inner side of the top of the correction block, so that external air can be passed into the expansion air bag, thereby driving the expansion silica gel to expand outward, thereby changing the support for the sole of the foot, and in actual use, the expansion silica gel has a certain hardness, so it can support the sole of the foot and buffer the impact force when people exercise vigorously.

[0018] 2. In the utility model, when it is necessary to discharge the air inside the inflatable airbag to change the expansion size of the inflatable airbag, the position of the sealing rod is changed by rotating the adjusting column. When the air hole extends into the inflatable airbag, the air inside the inflatable airbag can be released. When external gas is filled into the inflatable airbag through the air intake pipe, the elastic force of the spring drives the conical block and the support ring to seal each other, so that the air intake pipe is unidirectional, thereby preventing the gas inside the inflatable airbag from leaking from the air intake pipe.

[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
