Description

A pressure belt structure and posture correction belt Technical Field

[0001] This utility model belongs to the field of posture correction belts, specifically relating to a pressure belt structure and a posture correction belt. Background Technology

[0002] Most current posture correctors employ a composite structure of double-layer elastic fabric and homogeneous adhesive layer. The double-layer fabric enhances tensile strength, while the continuously coated homogeneous adhesive layer provides both adhesion and mechanical reinforcement. While this design improves durability compared to a single-layer structure, it still has significant limitations: First, the homogeneous adhesive layer results in a uniform overall rigidity, failing to meet the diverse mechanical needs of the shoulder, armpit, and lower back areas. Second, the continuous adhesive layer completely seals the gaps between the double-layer fabric, leading to a sharp decrease in breathability, especially in high-sweat areas like the armpits, where moisture and heat can accumulate, causing skin discomfort. Therefore, there is an urgent need to reconstruct the adhesive layer distribution logic based on the double-layer fabric structure, achieving excellent mechanical transfer and precise matching of functional zones through a non-uniform adhesive layer layout.

[0003] Existing posture correctors mostly employ a single or double layer of fabric combined with a homogeneous adhesive layer. While the adhesive layer achieves fabric bonding and tensile force transfer, it has significant drawbacks in practical applications: First, the homogeneous adhesive layer (uniformly distributed in thickness and area) leads to uniform rigidity across the belt, failing to adapt to the differentiated mechanical needs of the shoulders, armpits, and back. Second, the continuous adhesive layer completely seals the gaps between the double-layer fabric, resulting in a significant decrease in breathability, especially in the densely sweat-prone area of ​​the armpits, where moisture and heat can accumulate, exacerbating skin discomfort. Therefore, there is an urgent need to reconstruct the adhesive layer distribution logic based on the double-layer fabric structure, achieving excellent mechanical force transfer and precise matching of functional zones through a non-uniform adhesive layer layout. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a pressure belt structure and posture correction belt that achieves excellent mechanical transmission and functional zoning through a non-uniform adhesive layer layout.

[0005] This utility model provides a pressure belt structure, including a Y-shaped pressure belt. The first end of the Y-shaped pressure belt is a bifurcated end, which includes a first branch end and a second branch end. The first branch end is used to connect with the posture correction belt body at the shoulder, and the second branch end is used to connect with the posture correction belt body at the underarm. The second end of the Y-shaped belt is a guide end.

[0006] The Y-shaped pressure belt includes a first fabric layer, an adhesive layer, and a second fabric layer that are sequentially bonded together.

[0007] On the cross-sections of the first branch end, the second branch end, and the lead-in end, the cross-sectional area of ​​the adhesive layer on both sides is larger than that of the middle adhesive layer.

[0008] Furthermore, in the cross-section of the first branch end, the second branch end, and the lead-in end, the thickness of the adhesive layer on both sides is 1.3mm-1.6mm, and the thickness of the adhesive layer in the middle is 0.4mm-0.6mm.

[0009] Furthermore, in the cross-sections of the first branch end, the second branch end, and the guide tape end, the intermediate adhesive layer has a gap that forms a breathable area.

[0010] Furthermore, on the cross-section of the first branch end and the guide end, the air-permeable area is the first air-permeable area;

[0011] On the cross-section of the second branch end, the breathable area is the second breathable area;

[0012] The area ratio of the second breathable area to the second branch end is greater than the area ratio of the first breathable area to the first branch end and the guide belt end.

[0013] Furthermore, in the cross-section of the first branch end and the guide end, the width of the adhesive layer on the side closer to the second branch end is narrower than the width of the adhesive layer on the side away from the second branch end.

[0014] Furthermore, on the cross-section of the first branch end and the guide tape end, the width of the adhesive layer on the side closer to the second branch end is 12mm-16mm, and the width of the adhesive layer on the side away from the second branch end is 14mm-18mm.

[0015] Furthermore, the adhesive layer includes a first adhesive layer, which includes strip-shaped adhesive blocks extending at both ends of the lead end and the first branch end along their length, and also includes dispersed adhesive blocks disposed on the second branch end.

[0016] Furthermore, the strip-shaped adhesive block includes a first side strip-shaped adhesive block disposed on the side of the guide belt end and the first branch end away from the second branch end, a second side strip-shaped adhesive block disposed on the side of the guide belt end near the second branch end, a third side strip-shaped adhesive block disposed on the side of the first branch end near the second branch end, and a plurality of spaced strip-shaped adhesive blocks disposed between the second side strip-shaped adhesive block and the third side strip-shaped adhesive block and their connecting line and the first side strip-shaped adhesive block.

[0017] Furthermore, the adhesive layer also includes a second adhesive layer;

[0018] The second adhesive layer includes a fourth side strip adhesive block disposed on the side of the guide belt end and the first branch end away from the second branch end, a fifth side strip adhesive block disposed on the connection side of the guide belt end and the second branch end, and a sixth side strip adhesive block disposed on the connection side of the first branch end and the second branch end.

[0019] The second adhesive layer is disposed between the first fabric layer and the second fabric layer, and / or, between the first fabric layer and the first adhesive layer, and / or, between the second fabric layer and the first adhesive layer.

[0020] This utility model also provides a posture correction belt, including the above-mentioned pressure belt structure.

[0021] The contents of this utility model include

[0022] The beneficial effects of this utility model are:

[0023] First, the larger adhesive areas on both sides increase the rigidity of the Y-shaped compression band's edge areas, forming a support structure similar to reinforcing ribs. This effectively resists lateral torsional deformation (such as lateral stretching or torsion during wear), ensuring the Y-shaped compression band maintains its preset shape under stress and preventing structural loosening due to repeated pulling. The smaller adhesive area in the middle reduces the longitudinal stiffness of this area, giving it moderate tensile strength. When the wearer moves, the middle section can elastically deform with shoulder or armpit movements, providing necessary tension while avoiding excessive restraint.

[0024] Second, the high-rigidity areas on both sides of the adhesive layer can concentrate the tensile force to key stress points in the shoulder and armpit (such as skeletal support areas), while the low-rigidity area in the middle disperses the pressure on the soft tissue contact surface through elastic deformation, avoiding local pressure marks or obstructed blood circulation and improving wearing comfort. In addition, the elastic design of the middle adhesive layer allows the strap to slightly extend with limb movement in the shoulder or armpit, conforming to the changes in the curves of the human body (such as the stretching of the armpit skin when raising the arm), avoiding marks or restricted movement caused by excessive rigidity.

[0025] Third, combined with the Y-shaped bifurcation structure, the high support of the adhesive layers on both sides can strengthen the triangular mechanical framework formed by the "first branch end - second branch end - guide belt end", ensuring that the back pressure and shoulder tension work together to enhance the stability of the shoulder opening effect.

[0026] Fourth, during wear, the high rigidity of the adhesive layers on both sides can prevent the strap from curling or folding (especially in the easily rubbed area under the armpits), and it can still maintain the original outline of the Y-shaped structure after long-term use, thus extending the product's lifespan.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] As shown in Figures 1-9, this utility model provides a Y-shaped double-layer pressure belt, including a Y-shaped pressure belt 1. The first end of the Y-shaped pressure belt 1 is a bifurcated end, which includes a first branch end 101 and a second branch end 102. The first branch end 101 is used to connect with the posture correction belt body at the shoulder, and the second branch end 102 is used to connect with the posture correction belt body at the underarm. The second end of the Y-shaped belt is a guide end 103.

[0044] Referring to Figure 1, a posture correction belt is symmetrically provided with two sets of Y-shaped double-layer pressure belts. Specifically, the posture correction belt includes a posture correction belt body, Y-shaped pressure belt 1 and waist belt. The posture correction belt body is connected to the waist belt, and the two sets of Y-shaped pressure belts 1 are arranged symmetrically from left to right.

[0045] When worn, the main body of the posture corrector belt rests against the wearer's back. The two sides of the waistband wrap around the back to the front of the waist and abdomen, with the protruding parts of the two waistbands connected by Velcro. At this time, two Y-shaped pressure bands 1 are positioned on the wearer's back, with the guide ends 103 of the Y-shaped pressure bands 1 connected to the outer side of the waistband via Velcro. The first branch end 101 of the Y-shaped pressure band 1 pulls on the front shoulder, and the second branch end 102 pulls on the armpit area. The first branch end 101, the second branch end 102, and the guide end 103 form a Y-shaped pressure band. After the wearer's arms are inserted into the armholes, the elasticity of the fabric of the two Y-shaped pressure bands 1 and the pulling force at the end of the guide end 103 cause the wearer's shoulders to bear a reaction force, i.e., an outward rotational pulling force. The connection between the bifurcation end and the guide end 103 on the back creates back pressure due to the crisscrossing guides. The forces on the shoulders and back form a stable triangular force, effectively opening the shoulders of the wearer.

[0046] The Y-shaped pressure belt 1 includes a first fabric layer 11, an adhesive layer 12, and a second fabric layer 13 that are sequentially bonded together. That is, the Y-shaped pressure belt 1 has a double-layer fabric structure. The adhesive layer 12 is used to bond the first fabric layer 11 and the second fabric layer 13 together, and also serves as a tension rib of the Y-shaped pressure belt 1. After the Y-shaped pressure belt 1 is fitted with the waist belt, it provides support and pressure to the back.

[0047] Referring to Figures 2-6, the adhesive layer 12 includes a first adhesive layer 121, which includes strip-shaped adhesive blocks 1211 extending at both ends of the guide strap end 103 and the first branch end 101 along their length. The length direction of the strip-shaped adhesive blocks 1211 aligns with the tension direction of the guide strap end 103. The strip-shaped adhesive blocks 1211 guide the user to stretch the Y-shaped pressure strap 1 in the direction in which the adhesive blocks extend, facilitating proper wearing. Furthermore, it provides appropriate support for the muscles of the waist, back, and shoulders. It also includes dispersed adhesive blocks 1212 arranged on the second branch end 102. The coverage area of ​​the strip adhesive block 1211 is larger than that of the dispersed adhesive block 1212. When subjected to the tension of the guide belt end 103, on the one hand, the strip adhesive block 1211 can concentrate the force and maintain it in the same direction, while the dispersed adhesive block 1212 can disperse the force direction. The deformation of the fabric at the second branch end 102 is greater than that of the fabric at the first branch end 101 and the guide belt end 103. This can avoid the problem of skin constriction and pain caused by excessive tension in the armpit area and low fabric tensile strength elongation. On the other hand, since the adhesive coverage area of ​​the dispersed adhesive block 1212 at the second branch end 102 is reduced, a triangular hollow breathable area is left, solving the problem of stuffiness caused by poor breathability of double-layer fabric adhesive coating.

[0048] The Y-shaped double-layer pressure band provided by this utility model utilizes two different adhesive layers 12: strip-shaped adhesive blocks 1211 and dispersion adhesive blocks 1212. This achieves different rates of constant force elongation in different areas of the Y-shaped pressure band 1, resulting in different fabric deformations under the same tension. This applies different pressures to the waist, back, and shoulder muscles, creating an ideal posture-correcting effect and optimizing the comfort of the shaping product. Specifically, the dispersion adhesive blocks 1212 at the second branch end 102 make the hollow area under the armpit relatively larger than other areas. The fabric in the hollow area is not coated with adhesive, resulting in a high rate of constant force elongation and a large stretching space. Therefore, it can alleviate the problem of underarm constriction for the wearer, improve comfort, fabric smoothness, and breathability. The length direction of the strip-shaped adhesive blocks 1211 follows the direction of tension of the guide end 103. The strip-shaped adhesive blocks 1211 can guide the user to stretch the Y-shaped pressure band 1 in the direction of the extension of the adhesive blocks, facilitating correct wearing. Moreover, it can provide appropriate support for the waist, back, and shoulder muscles.

[0049] In one embodiment, the strip adhesive block 1211 includes a first side strip adhesive block 12111 disposed on the side of the guide tape end 103 and the first branch end 101 away from the second branch end 102, a second side strip adhesive block 12112 disposed on the side of the guide tape end 103 near the second branch end 102, a third side strip adhesive block 12113 disposed on the side of the first branch end 101 near the second branch end 102, and a plurality of spaced strip adhesive blocks 12114 disposed between the second side strip adhesive block 12112 and the third side strip adhesive block 12113 and their connecting line and the first side strip adhesive block 12111.

[0050] In this embodiment, by providing side strip-shaped adhesive blocks (first side strip-shaped adhesive block 12111, second side strip-shaped adhesive block 12112, and third side strip-shaped adhesive block 12113) on both sides of the guide belt end 103 and the first branch end 101, they can provide tensile pressure and also serve as edge sealing treatment for the first fabric layer 11 and the second fabric layer 13 at the corresponding side wall positions. This can improve the edge firmness of the first fabric layer 11 and the second fabric layer 13 at these locations and prevent curling deformation. The side strip-shaped adhesive blocks and the spacer strip-shaped adhesive blocks 12114 together form a strip-shaped adhesive block 1211, ensuring balanced tension throughout the width direction of the guide belt end 103 and the first branch end 101, ensuring sufficient tensile strength. Moreover, the spacer strip-shaped adhesive blocks 12114 are arranged at intervals to leave a first breathable area 14 along the length direction of the guide belt end 103 and the first branch end 101, improving their breathability.

[0051] In one embodiment, the first side strip adhesive block 12111, the second side strip adhesive block 12112, the third side strip adhesive block 12113, and a plurality of spaced strip adhesive blocks 12114 are parallel to each other. This ensures that the length direction of the entire strip adhesive block 1211 aligns with the direction of tension of the guide belt end 103, further facilitating the correct directional guidance of the guide belt end 103.

[0052] In one embodiment, the width of the first side strip adhesive block 12111, the second side strip adhesive block 12112, the third side strip adhesive block 12113 and the plurality of spaced strip adhesive blocks 12114 is 9mm-11mm and the thickness is 0.4mm-0.6mm.

[0053] In one embodiment, the strip-shaped adhesive block 1211 further includes a connecting adhesive block 12115 disposed on the end face of the guide strap end 103. The connecting adhesive block 12115 is interconnected with the first side strip-shaped adhesive block 12111, the second side strip-shaped adhesive block 12112, and a plurality of spaced strip-shaped adhesive blocks 12114. By providing the connecting adhesive block 12115, it is convenient for the wearer to pull the guide strap end 103 to connect with the waist belt, so that the first side strip-shaped adhesive block 12111, the second side strip-shaped adhesive block 12112, and the plurality of spaced strip-shaped adhesive blocks 12114 can be subjected to force simultaneously and evenly, ensuring that the tension in the cross-sectional direction of the guide strap end 103 and the first branch end 101 is balanced.

[0054] In one embodiment, the dispersion block 1212 includes a side-enclosing block 12121 and a central triangular block 12122;

[0055] The side-sealing adhesive block 12121 is disposed on the side of the second branch end 102, and one end of the side-sealing adhesive block 12121 is connected to the third side strip adhesive block 12113, and the other end is connected to the second side strip adhesive block 12112. The side-sealing adhesive block 12121 provides tensile pressure and also serves as an edge sealing treatment for the first fabric layer 11 and the second fabric layer 13 at the side position of the second branch end 102, which can improve the edge strength of the first fabric layer 11 and the second fabric layer 13 at this location and prevent curling deformation. The side-sealing adhesive block 12121 and the spaced strip adhesive blocks 12114 near the second branch end 102 enclose and form an intermediate adhesive coating area.

[0056] Multiple intermediate triangular rubber blocks 12122 are spaced apart within the intermediate adhesive area. This arrangement allows the tension from the Y-shaped pressure band 1 to be divided into the tension in the upper shoulder area at the first branch end 101 and the underarm area at the second branch end 102, depending on the direction of the wearing tension (the stretching direction of the guide strap end 103). At this time, the strip rubber block 1211 is oriented in the direction of the tension, and its coverage area is greater than that of the multiple intermediate triangular rubber blocks 12122 in the intermediate adhesive area. When subjected to the same tension, the strip rubber block 1211 can concentrate the force and maintain it in the same direction, while the multiple intermediate triangular rubber blocks 12122, being triangular strips, can disperse the force direction. The deformation of the fabric in the intermediate adhesive area is greater than that of the fabric at the first branch end 101 and the guide strap end 103. This avoids excessive tension in the underarm area and insufficient fabric elongation, which could cause skin constriction and pain due to the narrow underarm space. On the other hand, because the adhesive area in the middle coating area is reduced, a second breathable area 15 is left, which solves the problem of stuffiness caused by the non-breathable adhesive coating of double-layer fabric.

[0057] In one embodiment, the width of the intermediate triangular adhesive block 12122 is 8mm-12mm, and the thickness is 0.3mm-0.5mm. In this case, the adhesive layer thickness of the intermediate triangular adhesive block 12122 is less than that of the strip-shaped adhesive block 1211. Furthermore, because the intermediate triangular adhesive block 12122 has several isosceles triangular hollow areas, these hollow areas form a second breathable area 15 without an adhesive layer. This results in a relatively large hollow area under the armpit compared to other areas. Since the fabric is uncoated, it has a high elongation at break and a large stretching space, thus alleviating the problem of underarm constriction for the wearer and improving comfort, fabric smoothness, and breathability.

[0058] In one embodiment, the dispersed adhesive block 1212 includes a plurality of adhesive dots 12123 arranged in the middle of the second branch end 102. This arrangement provides excellent breathability. Furthermore, the adhesive-free areas between the adhesive dots 12123 allow the material to bend freely, and the band can stretch with the underarm skin when the arm moves, avoiding movement jamming or skin friction caused by excessive rigidity of the continuous adhesive layer.

[0059] In one specific embodiment, the spacing between several adhesive dots 12123 is 0.8-1.2mm, the diameter of adhesive dots 12123 is 0.8-1.2mm, and the distance between the end of the adhesive dot 12123 area and the spaced strip adhesive block 12114 near the second branch end 102 is 14mm-18mm.

[0060] In one embodiment, the adhesive layer 12 further includes a second adhesive layer 122;

[0061] The second adhesive layer 122 includes a fourth side strip adhesive block 1221 disposed on the side of the guide tape end 103 and the first branch end 101 away from the second branch end 102, a fifth side strip adhesive block 1222 disposed on the side where the guide tape end 103 and the second branch end 102 are connected, and a sixth side strip adhesive block 1223 disposed on the side where the first branch end 101 and the second branch end 102 are connected;

[0062] The second adhesive layer 122 is disposed between the first fabric layer 11 and the second fabric layer 13, and / or, disposed between the first fabric layer 11 and the first adhesive layer 121, and / or, disposed between the second fabric layer 13 and the first adhesive layer 121.

[0063] By providing a second adhesive layer 122, which is disposed on the sides of the first branch end 101, the second branch end 102, and the guide tape end 103, the edge strength of the fabric can be further reinforced, preventing curling and deformation. Additionally, the second adhesive layer 122 can be bonded to a portion of the first adhesive layer 121, increasing the thickness of the strip-shaped adhesive blocks 1211 and / or the dispersed adhesive blocks 1212, thereby improving their tensile strength.

[0064] In a preferred embodiment with the enclosing adhesive block 12121, referring to Figure 2, the second fabric layer 12, the fourth side strip adhesive block 1221, the first side strip adhesive block 12111, and the first fabric layer 11 are arranged sequentially; the second fabric layer 12, the fifth side strip adhesive block 1222, the second side strip adhesive block 12112, and the enclosing adhesive block 12121 are arranged sequentially near the guide tape end 103, and the first fabric layer 11 is arranged sequentially; the second fabric layer 12, the sixth side strip adhesive block 1223, the third side strip adhesive block 12113, and the enclosing adhesive block 12121 are arranged sequentially near the first branch end 101, and the first fabric layer 11 is arranged sequentially.

[0065] In a preferred embodiment without the enclosure adhesive block 12121, referring to Figure 6, the second fabric layer 12, the fourth side strip adhesive block 1221, the first side strip adhesive block 12111, and the first fabric layer 11 are arranged sequentially in the extending direction of the guide tape end 103 and the first branch end 101; the second fabric layer 12, the fifth side strip adhesive block 1222, the second side strip adhesive block 12112, and the first fabric layer 11 are arranged sequentially; the second fabric layer 12, the sixth side strip adhesive block 1223, the third side strip adhesive block 12113, and the first fabric layer 11 are arranged sequentially. On the second branch end 102, the second fabric layer 12, the fifth side strip adhesive block 1222, the sixth side strip adhesive block 1223, and the first fabric layer 11 are arranged sequentially.

[0066] In one embodiment, the cross-sectional area of ​​the second adhesive layer 122 is larger than that of the first adhesive layer 121. This configuration increases the thickness of the outer edge of the Y-shaped pressure belt 1, thereby improving the shaping effect of the Y-shaped pressure belt 1.

[0067] In one embodiment, the first fabric layer 11 and / or the second fabric layer 13 are breathable fabrics. This provides breathability in areas without adhesive coating, improving wearing comfort.

[0068] This utility model also provides a posture correction belt, including the above-mentioned Y-shaped double-layer pressure belt.

[0069] This utility model also provides a pressure band structure, referring to Figure 1, including a Y-shaped pressure band 1. The first end of the Y-shaped pressure band 1 is a bifurcated end, which includes a first branch end 101 and a second branch end 102. The first branch end 101 is used to connect with the posture correction band body at the shoulder, and the second branch end 102 is used to connect with the posture correction band body at the armpit. The second end of the Y-shaped band is a guide end 103. The working principle of the pressure band structure is the same as that of the above-mentioned Y-shaped double-layer pressure band, and will not be repeated here.

[0070] The Y-shaped pressure belt 1 includes a first fabric layer 11, an adhesive layer 12, and a second fabric layer 13 that are sequentially bonded together; that is, the Y-shaped pressure belt 1 has a double-layer fabric structure. The adhesive layer 12 is used to bond the first fabric layer 11 and the second fabric layer 13 together, and also serves as a tension rib of the Y-shaped pressure belt 1, providing support and pressure to the back after the Y-shaped pressure belt 1 is engaged with the waist belt.

[0071] Referring to Figures 7-9, on the cross-sections of the first branch end 101, the second branch end 102, and the guide tape end 103, the cross-sectional area of ​​the adhesive layers 12 on both sides is greater than that of the middle adhesive layer 12.

[0072] This setting has the following effect:

[0073] First, the larger area of ​​the adhesive layers 12 on both sides can improve the rigidity of the side edge area of ​​the Y-shaped pressure band 1, forming a support structure similar to a reinforcing rib. This can effectively resist lateral torsional deformation (such as lateral stretching or torsion during wear), ensuring that the Y-shaped pressure band 1 maintains its preset shape under force and preventing structural loosening due to repeated pulling. The smaller area of ​​the middle adhesive layer 12 reduces the longitudinal stiffness of this area, giving it moderate tensile strength. When the wearer moves, the middle part can elastically deform with shoulder or armpit movements, providing necessary tension while avoiding excessive restraint.

[0074] Second, the high-rigidity areas of the two side adhesive layers 12 can concentrate the tensile force to key stress points in the shoulders and armpits (such as skeletal support areas), while the low-rigidity area in the middle disperses the pressure on the soft tissue contact surface through elastic deformation, avoiding local pressure marks or obstructed blood circulation and improving wearing comfort. In addition, the elastic design of the middle adhesive layer 12 allows the strap to slightly extend with limb movement in the shoulders or armpits, conforming to the changes in the curves of the human body (such as the stretching of the armpit skin when raising the arm), avoiding marks or restricted movement caused by excessive rigidity.

[0075] Third, combined with the Y-shaped bifurcation structure, the high support of the adhesive layers 12 on both sides can strengthen the triangular mechanical framework formed by "first branch end 101-second branch end 102-guide end 103", ensuring that the back pressure and shoulder tension work together to enhance the stability of the shoulder opening effect.

[0076] Fourth, during wear, the high rigidity of the adhesive layers 12 on both sides can prevent the strap from curling or folding (especially in the easily rubbed area under the armpits), and it can still maintain the original outline of the Y-shaped structure after long-term use, thus extending the product's lifespan.

[0077] In one embodiment, on the cross-section of the first branch end 101, the second branch end 102, and the guide strap end 103, the thickness of the adhesive layers 12 on both sides is 1.3mm-1.6mm, and the thickness of the adhesive layer 12 in the middle is 0.4mm-0.6mm. Excessive thickness of the adhesive layers 12 on both sides would lead to structural stiffness and increase weight, affecting wearing comfort; conversely, insufficient thickness would result in insufficient support and poor posture correction. Therefore, the thickness of the adhesive layers 12 on both sides is 1.3mm-1.6mm. The thickness of the adhesive layer 12 in the middle is less than half that of the adhesive layers 12 on both sides, which reduces longitudinal stiffness, allowing the middle area to stretch moderately with limb movement and avoiding restricted movement. Simultaneously, elastic deformation disperses local pressure, reducing the feeling of pressure on soft tissues.

[0078] In one embodiment, the adhesive layer 12 in the cross-section of the first branch end 101, the second branch end 102, and the guide tape end 103 has a gap, which forms a breathable area. In a specific embodiment, referring to Figure 7, the adhesive layer 12 between the first branch end 101 and the guide tape end 103 is composed of a plurality of spaced strip adhesive blocks 12114, and the outer adhesive layers 12 are respectively the first side strip adhesive block 12111, the second side strip adhesive block 12112, and the third side strip adhesive block 12113. At this time, the gap between two adjacent spaced strip adhesive blocks 12114, the gap between one side spaced strip adhesive block 12114 and the first side strip adhesive block 12111, and the gap on the other side... The spacing between 12114, the second side strip adhesive block 12112, and the third side strip adhesive block 12113 together forms the breathable area of ​​the first branch end 101 and the guide strap end 103. Referring to Figure 8, the adhesive layer 12 in the middle of the second branch end 102 is a central triangular adhesive block 12122, and the hollow interior of the central triangular block 12122 serves as the spacing for forming the breathable area. Referring to Figure 9, the adhesive layer 12 in the middle of the second branch end 102 can also be a dot adhesive 12123, in which case the spacing of the dot adhesive 12123 serves as the spacing for forming the breathable area. This arrangement allows for a breathable area in the middle portion of the first branch end 101, the second branch end 102, and the guide strap end 103. This increases the area of ​​the fabric layer at the central adhesive layer 12 that directly contacts the skin, facilitating sweat evaporation and reducing stuffiness.

[0079] In one embodiment, the breathable area on the cross-section of the first branch end 101 and the guide end 103 is a first breathable area 14;

[0080] On the cross-section of the second branch end 102, the breathable area is the second breathable area 15;

[0081] The area ratio of the second breathable area 15 and the second branch end 102 is greater than the area ratio of the first breathable area 14, the first branch end 101, and the guide end 103.

[0082] With this design, the armpits have a high density of sweat glands and experience frequent friction during activity, resulting in a significantly higher need for ventilation compared to the shoulders and back. Therefore, increasing the area of ​​the second ventilation zone 15 can improve the ventilation effect of the armpit area, accelerate sweat evaporation, reduce stuffiness and bacterial growth, and prevent skin redness or eczema. At the same time, because the area of ​​the second ventilation zone 15 is larger than that of the second branch end 102, the second branch end 102 can better conform to the skin folds when bent under the armpit, reducing frictional resistance and increasing flexibility.

[0083] In one embodiment, referring to FIG7, on the cross-section of the first branch end 101 and the guide end 103, the width of the adhesive layer 12 on the side closer to the second branch end 102 is narrower than the width of the adhesive layer 12 on the side away from the second branch end 102.

[0084] With this configuration, the cross-sections of the first branch end 101 and the guide end 103 are asymmetrical, with a smaller area on the side closer to the armpit and a larger area on the side closer to the thoracic cavity. Since the thoracic cavity is a relatively static area, its displacement frequency and range are relatively small. Therefore, the wider width can serve as supporting bones in the thoracic region, significantly improving the support effect (e.g., ribs). The large area of ​​the adhesive layer 12 provides stable pressure output through high rigidity, ensuring the posture corrector adheres tightly to the thoracic cavity and preventing slippage. The armpit area, on the other hand, is a relatively active area with a relatively large displacement frequency and range. A narrower width reduces the restraint intensity in this active area. The skin in the armpit area is sensitive and frequently active (e.g., raising and swinging the arm). A smaller adhesive layer area reduces frictional resistance caused by material accumulation, preventing the edges of the adhesive layer from scratching the skin during movement. Thus, the narrower adhesive layer 12, several spaced adhesive blocks, and the wider adhesive layer 12 form a mechanical gradient of "flexible active area transition zone rigid support zone." Preferably, on the cross-section of the first branch end 101 and the guide tape end 103, the width of the adhesive layer 12 near the second branch end 102 is 12mm-16mm, and the width of the adhesive layer 12 away from the second branch end 102 is 14mm-18mm. It should be noted that the width of the adhesive layer 12 near the second branch end 102 is always less than the width of the adhesive layer 12 away from the second branch end 102.

[0085] In one embodiment, the adhesive layer 12 includes a first adhesive layer 121, which includes strip-shaped adhesive blocks 1211 extending at both ends of the lead-in end 103 and the first branch end 101 along their length, and also includes dispersed adhesive blocks 1212 disposed on the second branch end 102.
