Description

Technical Field

[0001] The utility model relates to the technical field of insoles, and in particular to an insole for conveniently adjusting arch support. Background Art

[0002] In modern life, people pay more and more attention to foot health. The arch is an important load-bearing and cushioning structure of the foot. Its support status directly affects daily activities such as walking and standing, and its comfort and safety. A functional insole with convenient arch support adjustment is designed to meet the personalized needs of different groups of people for arch support. Through a specific structure or mechanism, it allows users to easily adjust the height, curvature or strength of the arch support according to their own arch shape and different activity scenarios, thereby providing a more fitting and comfortable support for the arch, relieving foot fatigue and reducing the risk of foot diseases caused by improper arch support.

[0003] Early arch support insoles were mostly integral structures, usually made of a single material pressed through a fixed mold. The support strength of the arch support part was completely determined by the hardness of the material itself and was fixed. Insoles with this structure had obvious limitations. Due to differences in weight and activity intensity among different individuals, the demand for arch support strength was also different. The same pair of insoles could not meet different support strength requirements. For people with a larger weight or a higher activity intensity, the foot would often fatigue quickly due to insufficient support strength, while for people with a lighter weight or a lower activity intensity, discomfort would occur due to excessive support strength. In order to solve this problem, some existing arch support insoles began to use materials of different hardness. The combined structure uses multiple layers of materials with different hardness to stack at the arch support part, and changes the support strength by increasing or decreasing the number of material layers. This structure has broadened the range of support strength options to a certain extent, and avoided the problem that the early integral structure could not adapt to different support strength requirements. However, these existing structures still have shortcomings. The number of material layers or hardness combinations at the arch support part are pre-set through a specified mold, and the support strength adjustment options of each insole are fixed. Users can only choose from a limited number of strength levels. They cannot flexibly adjust the support strength of the arch support part according to their own real-time usage needs, and it is difficult to provide adaptive support as the usage scenario changes.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 2 、 Figure 4 and Figure 5 The present invention provides an embodiment of an insole for conveniently adjusting arch support, comprising an insole body 1, a quick-change mechanism 2 being provided at the top middle portion of the insole body 1, and a ventilation mechanism 3 being provided on the right side of the inner wall of the insole body 1;

[0029] The quick-change mechanism 2 includes an inclined arched support block 201, the bottom end of the inclined arched support block 201 is arranged at the middle of the top of the insole body 1, the bottom end of the inclined arched support block 201 is engaged with the middle of the top of the insole body 1, and a pad 202 is provided on the inner wall of the inclined arched support block 201. The four corners of the bottom end of the inclined arched support block 201 are fixedly connected to the limiting posts 203. The four limiting posts 203 at the bottom end of the inclined arched support block 201 are aligned with the mounting holes at the corresponding positions in the middle of the top of the insole body 1, and pressed downward to insert the limiting posts 203 into the holes. The left and right sides of the front of the inclined arched support block 201 are both provided with sliding grooves 20 4. The inner wall of the slide groove 204 is slidably connected with a clamping strip 205. The left and right sides of the front of the backing plate 202 are provided with clamping slots 207. The outer wall of the clamping strip 205 is engaged with the inner wall of the corresponding clamping slot 207. When the backing plate 202 needs to be replaced, the clamping strip 205 in the slide groove 204 can be pushed to slide the clamping strip 205 along the slide groove 204. When the clamping strip 205 is separated from the clamping slot 207 at the front of the backing plate 202, the backing plate 202 can be taken out. After replacing the new backing plate 202, the clamping strip 205 is slid in the opposite direction so that its outer wall is re-engaged with the inner wall of the corresponding clamping slot 207, thereby fixing the backing plate 202. The bottom end of the limiting column 203 is provided with a locking component 206.

[0030] The locking assembly 206 includes a plurality of arc-shaped clamping blocks 2061, the inner walls of which are fixedly connected to the left and right sides of the bottom end of the corresponding limiting column 203, respectively. A hollow snap plate 2062 is provided at the bottom end of the limiting column 203, and arc-shaped partitions 2063 are fixedly connected to the left and right sides of the top of the inner wall of the hollow snap plate 2062.

The arc-shaped clamping blocks 2061 on the left and right sides of the bottom end of the limiting column 203 are engaged with the arc-shaped partitions 2063 on the top of the inner wall of the hollow snap plate 2062, thereby preliminarily completing the connection and fixation between the inclined arched support block 201 and the insole body 1.

[0031] Specifically, when installing or replacing the inclined arched support block 201, align the four limiting posts 203 at the bottom end of the inclined arched support block 201 with the mounting holes at the corresponding positions in the middle of the top end of the insole body 1, and press downward to insert the limiting posts 203 into the holes. At this time, the arc-shaped clamping blocks 2061 on the left and right sides of the bottom end of the limiting posts 203 will be engaged with the arc-shaped partitions 2063 on the top of the inner wall of the hollow buckle plate 2062, preliminarily completing the connection and fixation between the inclined arched support block 201 and the insole body 1. If the pad 202 needs to be replaced, the clip 205 in the slide groove 204 can be pushed to make the clip 205 slide along the slide groove 204. When the clip 205 is out of the slot 207 at the front of the pad 202, the pad 202 can be taken out. After replacing the new pad 202, slide the clip 205 in the opposite direction so that its outer wall re-engages with the inner wall of the corresponding slot 207, thereby fixing the pad 202. By replacing pads 202 with different thicknesses or hardnesses, the arch support strength can be adjusted.

[0032] Reference Figure 1 、 Figure 4 and Figure 6 The ventilation mechanism 3 includes an elastic airbag 301. When the elastic airbag 301 is reset, external air will enter the elastic airbag 301 through the connecting hose 302. The outer wall of the elastic airbag 301 is fixedly connected to the right side of the inner wall of the insole body 1. The front and rear sides of the elastic airbag 301 are both connected with the connecting hose 302. The outer walls of the two connecting hoses 302 pass through the front and rear sides of the insole body 1 respectively. The left side of the elastic airbag 301 is connected with a ventilation hose 303. The left end of the ventilation hose 303 is connected with a dispersion block 304. A plurality of exhaust holes 305 are provided on the top left side of the insole body 1. The foot generates pressure on the insole body 1, which squeezes the elastic airbag 301 located on the right side of the inner wall. After the elastic airbag 301 is pressurized, the internal air is transported to the dispersion block 304 through the ventilation hose 303, and then the dispersion block 304 disperses the air to the plurality of exhaust holes 305 on the top left side of the insole body 1 for discharge, thereby achieving ventilation for the foot. The front and rear sides of the inner wall of the insole body 1 are both provided with interception components 306.

[0033] The interception assembly 306 includes two inclined hollow blocks 3061. The outer walls of the two inclined hollow blocks 3061 are respectively fixedly connected to the front and rear sides of the inner wall of the insole body 1. A plurality of filter holes 3062 are formed on the side of the two inclined hollow blocks 3061 that are separated from each other. The bottom of the inner wall of the inclined hollow blocks 3061 is fixedly connected to an arc-shaped interception strip 3063. Air first passes through the inclined hollow blocks 3061. The filter holes 3062 on the side of the inclined hollow blocks 3061 that are separated from each other can initially filter the air. The arc-shaped interception strip 3063 at the bottom of the inner wall can further intercept impurities in the air, preventing impurities from entering the elastic airbag 301 and affecting its normal operation.

[0034] Specifically, when the user walks or exercises, the foot generates pressure on the insole body 1, which will squeeze the elastic airbag 301 located on the right side of the inner wall. After the elastic airbag 301 is pressurized, the internal air is transported to the dispersion block 304 through the ventilation hose 303, and then the dispersion block 304 disperses the air to the multiple exhaust holes 305 on the top left side of the insole body 1 for discharge, thereby achieving ventilation of the foot. When the foot pressure decreases and the elastic airbag 301 is reset, the outside air will enter the elastic airbag 301 through the connecting hose 302. During this process, the air will first pass through the inclined hollow block 3061. The filter hole 3062 on the side away from the inclined hollow block 3061 can perform preliminary filtration on the air. The arc-shaped interception strip 3063 at the bottom of the inner wall can further intercept impurities in the air to prevent impurities from entering the elastic airbag 301 and affecting its normal operation, thereby providing ventilation for the inside of the insole.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 The forefoot sole plate 4 is fixedly connected to the left side of the top of the insole body 1, providing a special load-bearing and support surface for the user's forefoot, and the heel pad ring 5 is fixedly connected to the right side of the top of the insole body 1, which wraps and supports the user's heel in a surround manner; a plurality of toe limiting grooves 6 are provided on the left side of the top of the forefoot sole plate 4, which limit the toes and prevent them from sliding on the insole during walking or exercise; a plurality of wear-resistant blocks 7 are fixedly connected to the right side of the top of the forefoot sole plate 4, which enhance the wear resistance of the forefoot main force-bearing area on the right side of the top of the forefoot sole plate 4; a plurality of corrugated anti-skid bottom plates 8 are fixedly connected to the bottom of the insole body 1, which can increase the friction between the insole body 1 and the inner bottom surface of the shoe, and a plurality of corrugated grooves 9 are provided on the top of the inclined arch support block 201 to increase the friction between the top of the inclined arch support block 201 and the skin of the user's arch;

[0036] Specifically, the forefoot sole 4 can provide a special load-bearing and support surface for the user's forefoot, dispersing the pressure on the forefoot when walking or standing, and avoiding soreness of the forefoot due to concentrated force, and the heel pad ring 5 can wrap and support the user's heel in a surrounding manner, increase the fit between the heel and the insole, reduce the shaking of the heel when walking, and at the same time cushion the impact force generated when the heel lands, protecting the bones and soft tissues of the heel area, and the toe limiting groove 6 can correspond to each toe of the user one by one, play a limiting role for the toes, prevent the toes from sliding randomly on the insole and squeezing each other when walking or exercising, and reduce the friction between the toes. The wavy anti-skid bottom plate 8 can increase the friction between the insole body 1 and the bottom surface of the shoe to prevent the insole from sliding and shifting in the shoe, ensuring that the insole is always in the correct position during use. The corrugated groove 9 increases the friction between the top of the inclined arch support block 201 and the skin of the user's arch. At the same time, these corrugated grooves can also play a certain role in ventilation, reducing the discomfort caused by stuffiness in the arch.

[0037] Reference Figure 1 、 Figure 2 and Figure 3The other end of the connecting hose 302 is connected to the outer side of the corresponding inclined hollow block 3061, so that after the external air enters through the inclined hollow block 3061, it flows smoothly into the elastic airbag 301 through the connecting hose 302, forming a complete air circulation channel. The air inlet side of the inclined hollow block 3061 adopts an inclined design, which can better fit the internal space structure of the shoe, making it easier for external air to enter the inclined hollow block 3061; the outer wall of the hollow buckle plate 2062 is engaged with the bottom of the insole body 1, and the hollow buckle is engaged. The plate 2062 is stably fixed to the bottom of the insole body 1. The inner wall of the hollow snap plate 2062 is the same size as the outer wall bottom of the limiting post 203, so that the bottom end of the limiting post 203 can fit tightly against the inner wall of the hollow snap plate 2062. The forefoot sole plate 4 adopts a breathable and wear-resistant design, allowing air to circulate smoothly in the forefoot area, reducing sweat accumulation and keeping the forefoot dry. The inner wall bottom of the heel pad ring 5 is engaged with the top of the elastic airbag 301, which can fix the top of the elastic airbag 301.

[0038] Specifically, the other ends of the connecting hoses 302 are respectively connected to the outer sides of the corresponding inclined hollow blocks 3061, so that after the external air enters through the inclined hollow blocks 3061, it flows smoothly into the elastic airbag 301 through the connecting hoses 302, forming a complete air circulation channel, ensuring the air circulation of the ventilation mechanism 3, and the air intake side of the inclined hollow blocks 3061 adopts an inclined design, which can better fit the internal space structure of the shoe, facilitate the smooth entry of external air into the inclined hollow blocks 3061, and at the same time reduce the resistance when the air enters, thereby improving the air intake efficiency. The outer wall of the hollow snap plate 2062 is engaged with the bottom of the insole body 1, and the hollow snap plate 2062 is stably fixed to the bottom of the insole body 1, providing a solid foundation for the fixation of the limit column 203. The hollow snap plate 2062 The inner wall size is consistent with the size of the bottom end of the outer wall of the limiting column 203, which can make the bottom end of the limiting column 203 fit closely with the inner wall of the hollow snap plate 2062, enhance the stability of the connection between the two, avoid the limiting column 203 from shaking in the hollow snap plate 2062, and ensure the stable installation of the inclined arch support block 201. The forefoot sole 4 adopts a breathable and wear-resistant design, so that the air in the forefoot area can circulate smoothly, reduce sweat accumulation, and keep the forefoot dry. The bottom of the inner wall of the heel pad ring 5 is engaged with the top of the elastic airbag 301, which can fix the top of the elastic airbag 301 and prevent the elastic airbag 301 from shifting when squeezed or reset, ensuring that the elastic airbag 301 can be stably inflated and deflated, and ensuring the normal operation of the ventilation mechanism 3.

[0039] Working principle: First, when installing or replacing the inclined arched support block 201, the four limiting posts 203 at the bottom end of the inclined arched support block 201 need to be accurately aligned with the mounting holes at the corresponding positions in the middle of the top end of the insole body 1, and then downward pressure is applied to insert the limiting posts 203 into the holes. At this time, the arc-shaped clamping blocks 2061 on the left and right sides of the bottom end of the limiting posts 203 will engage with the arc-shaped partitions 2063 on the top of the inner wall of the hollow buckle plate 2062. At this point, the connection between the inclined arched support block 201 and the insole body 1 is preliminarily completed. If the position of the pad 202 needs to be adjusted or replaced, the clip 205 in the slide groove 204 can be pushed to slide along the slide groove 204. When the clip 205 is out of the slot 207 at the front of the pad 202, the pad 202 can be taken out. After replacing the new pad 202, the clip 205 is slid in the opposite direction to re-engage the outer wall of the pad with the inner wall of the corresponding slot 207, thereby fixing the pad 202. By replacing the pad 202 with different thicknesses or hardnesses, the arch support strength can be adjusted.

[0040] And through the ventilation mechanism 3, when the user is walking or exercising, the foot will exert pressure on the insole body 1, thereby squeezing the elastic airbag 301 located on the right side of the inner wall. After the elastic airbag 301 is pressurized, the air inside it will be transported to the dispersion block 304 through the ventilation hose 303, and then the dispersion block 304 will disperse the air to the multiple exhaust holes 305 on the top left side of the insole body 1 for discharge, thereby achieving ventilation of the foot. When the foot pressure decreases and the elastic airbag 301 is reset, the outside air will enter the elastic airbag 301 through the connecting hose 302. In this process, the air will first pass through the inclined hollow block 3061. The filter hole 3062 on the side away from the inclined hollow block 3061 can perform preliminary filtration on the air. The arc-shaped interception strip 3063 at the bottom of the inner wall can further intercept impurities in the air to prevent impurities from entering the elastic airbag 301 and affecting its normal operation, thereby giving the insole a ventilation function.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
