Description

Technical Field

[0001] This application belongs to the field of daily necessities technology, and more specifically, relates to an anti-slip buckle structure and a waist support belt. Background Technology

[0002] In the design of various protective gear products (such as lumbar support belts, knee pads, etc.), in order to adapt to the different body shapes of different users, it is usually necessary to set an adjustable strap structure to adjust the tightness of the protective gear.

[0003] Adjustment methods often employ a combination of a sliding buckle structure and a strap structure. For example, an elastic band and a tension band can be used in conjunction with a sliding buckle structure. Specifically, one end of the elastic band is connected to the protective gear body, and the other end passes through the sliding buckle and is connected to the protective gear body. One end of the tension band is connected to the protective gear body, and the other end passes through the sliding buckle to form a free end for the user to pull and adjust. By pulling the tension band, the elastic band is tightened, thereby adjusting the overall tightening force.

[0004] Because the tension band needs to be threaded inside the slip buckle and slides relative to it during adjustment, the surface of the slip buckle is usually designed to be relatively smooth to reduce frictional resistance when the tension band moves. However, this design means that when the user pulls the tension band and the force is transmitted through the slip buckle to the elastic band, the slip buckle is prone to twisting or deflection due to uneven force. This causes the contact surface between the slip buckle and the elastic band and tension band to change from an ideal contact surface to an end-compression state, resulting in the elastic band and tension band being squeezed to both ends of the slip buckle. This causes the force transmission path to be obstructed and efficiency reduced. This not only increases the pulling force required for adjustment, making tension adjustment difficult, but also affects the overall symmetry and comfort of wearing the protective gear, reducing the user experience. Utility Model Content

[0005] The purpose of this application is to provide an anti-slip buckle structure and a waist support belt to solve the technical problem that the straps of protective gear products in the prior art are prone to twisting inside the buckle.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an anti-slip buckle structure is provided, comprising: a slip buckle, the slip buckle having a through hole, the slip buckle including buckle walls located on opposite sides of the through hole; and an anti-slip member, the anti-slip member covering at least one buckle wall, the side of the anti-slip member in contact with the buckle wall having a first anti-slip portion, and the side of the anti-slip member away from the buckle wall being used to connect an external strap to limit the sliding of the external strap relative to the buckle wall.

[0007] In one alternative embodiment, the first anti-slip part includes a plurality of anti-slip particles, which are spaced apart on the side of the anti-slip member that contacts the buckle wall.

[0008] In one alternative embodiment, the first anti-slip part includes a plurality of anti-slip strips, which are spaced apart on the side of the anti-slip member that contacts the buckle wall.

[0009] In one alternative embodiment, the first anti-slip portion includes an anti-slip layer connected to the side of the anti-slip member that contacts the buckle wall; or, the first anti-slip portion includes raised anti-slip textures disposed on the side of the anti-slip member that contacts the buckle wall.

[0010] In one alternative embodiment, the material of the first anti-slip part is silicone, rubber, or latex.

[0011] In one alternative embodiment, the anti-slip element is made of fabric.

[0012] In one alternative embodiment, one end of the anti-slip member passes through the through hole and is fixedly connected to the other end of the anti-slip member by stitching to cover the buckle wall.

[0013] In one alternative embodiment, one end of the anti-slip member passes through a through hole and is connected to the other end of the anti-slip member to cover the buckle wall, and at least one end of the anti-slip member is provided with a connecting portion for fixed connection with an external strap.

[0014] Another objective of this application is to provide a waist support belt, including a waist belt and an anti-slip buckle structure as described above, the anti-slip buckle structure being connected to the waist belt.

[0015] In one optional embodiment, the belt includes a main body, an elastic band, and a tension band. One end of the elastic band is fixed to the main body, and the other end of the elastic band passes through the through hole of the sliding buckle and is fixed to the main body. The elastic band is fixedly connected to the anti-slip component. One end of the tension band is fixed to the main body, and the other end of the tension band passes through the through hole of the sliding buckle to form an adjustment end.

[0016] The beneficial effects of the anti-slip buckle structure and waist support belt provided in this application are as follows: Compared with the prior art, the anti-slip buckle structure of this application embodiment, by setting an anti-slip member, which covers at least one buckle wall of the buckle, and having a first anti-slip portion on the anti-slip member in contact with the buckle wall, increases the friction between the anti-slip member and the buckle. An external strap passes through the through-hole of the buckle and connects to the side of the anti-slip member facing away from the buckle wall, thereby restricting the sliding of the external strap relative to the buckle and ensuring the buckle maintains a stable posture under force. Furthermore, the stability of the buckle's posture also improves the overall symmetry and comfort of the protective gear, enhancing the user experience. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] In the design of various protective gear products (such as lumbar support belts, knee pads, etc.), in order to adapt to the different body shapes of different users, it is usually necessary to set an adjustable strap structure to adjust the tightness of the protective gear.

[0025] Adjustment methods often employ a combination of a sliding buckle structure and a strap structure. For example, an elastic band and a tension band can be used in conjunction with a sliding buckle structure. Specifically, one end of the elastic band is connected to the protective gear body, and the other end passes through the sliding buckle and is connected to the protective gear body. One end of the tension band is connected to the protective gear body, and the other end passes through the sliding buckle to form a free end for the user to pull and adjust. By pulling the tension band, the elastic band is tightened, thereby adjusting the overall tightening force.

[0026] Because the tension band needs to be threaded inside the slip buckle and slides relative to it during adjustment, the surface of the slip buckle is usually designed to be relatively smooth to reduce frictional resistance when the tension band moves. However, this design means that when the user pulls the tension band and the force is transmitted through the slip buckle to the elastic band, the slip buckle is prone to twisting or deflection due to uneven force. This causes the contact surface between the slip buckle and the elastic band and tension band to change from an ideal contact surface to an end-compression state, resulting in the elastic band and tension band being squeezed to both ends of the slip buckle. This causes the force transmission path to be obstructed and efficiency reduced. This not only increases the pulling force required for adjustment, making tension adjustment difficult, but also affects the overall symmetry and comfort of wearing the protective gear, reducing the user experience.

[0027] Please refer to the following: Figures 1 to 5The anti-slip buckle structure 10 provided in this application embodiment will now be described. The anti-slip buckle structure 10 includes: a sliding buckle 11, which has a through hole 111 and includes buckle walls 112 located on opposite sides of the through hole 111; and an anti-slip member 121, which covers at least one buckle wall 112. The side of the anti-slip member 121 that contacts the buckle wall 112 has a first anti-slip portion 122, and the side of the anti-slip member 121 that faces away from the buckle wall 112 is used to connect an external strap 200 to limit the sliding of the external strap 200 relative to the buckle wall 112.

[0028] External strap 200 refers to an adjusting strap, such as elastic band 22, tension band 23, etc., which can be elastic or non-elastic. Sliding buckle 11 refers to a buckle structure with a through hole 111, which is used for the anti-slip part 121 or other components to pass through, and the opposite sides of the through hole 111 form buckle walls 112.

[0029] The slider 11 can be formed from rigid plastic or metal. The slider 11 can be rectangular, with rounded transition surfaces at both ends (e.g.,...). Figure 1 (As shown); a rectangular through hole 111 can be provided in the middle of the sliding buckle 11, and transition arc surfaces can be provided at both ends of the rectangular through hole 111. The specific shapes of the sliding buckle 11 and the through hole 111 can be designed as needed. There can be one through hole 111, and all straps pass through one through hole 111; there can also be two or more through holes 111, which can be set according to the straps.

[0030] The anti-slip component 121 covers at least one snap wall 112, and has a first anti-slip portion 122 on the side in contact with the snap wall 112 to increase the friction with the snap 11. The anti-slip component 121 can be strip-shaped or sheet-shaped. Specifically, the anti-slip component 121 can be made of flexible plastic, silicone, latex, rubber, or fabric.

[0031] The buckle wall 112 refers to the two side wall structures on the slide buckle 11 that are arranged opposite each other in the width direction X around the through hole 111, and are used to support and guide the belt passing through the through hole 111.

[0032] The first anti-slip part 122 specifically refers to a protrusion or texture on the side of the anti-slip part 121 that contacts the buckle wall 112, and is made of a friction elastic material. Its structure can take the form of anti-slip particles, anti-slip ribs, or anti-slip coating, etc., and restricts the sliding or twisting of the anti-slip part 121 by contacting the buckle wall 112 of the sliding buckle 11.

[0033] The anti-slip component 121 covers the buckle wall 112. The covering method can be to directly adhere to the surface of the buckle 11, or to pass through the through hole 111 multiple times and wrap around the surface of the buckle 11. When the anti-slip component 121 covers the buckle wall 112 of the buckle 11, the first anti-slip part 122 is in close contact with the buckle wall 112 of the buckle 11, increasing the friction.

[0034] In some embodiments, after one end of the anti-slip member 121 passes through the through hole 111 of the slide buckle 11, it can be connected to the other end of the anti-slip member 121 to form a ring structure covering the surface of the slide buckle 11, making the connection more stable.

[0035] The side of the anti-slip component 121 facing away from the buckle wall 112 is used to connect the external strap 200. The external strap 200 is fixed to the anti-slip component 121, and the anti-slip component 121 contacts the buckle wall 112 through the first anti-slip part 122, thereby restricting the sliding of the external strap 200 relative to the buckle wall 112. The connection between the anti-slip component 121 and the external strap 200 can be a detachable connection, such as a snap connection or Velcro connection; or a fixed connection, such as an adhesive connection or a sewn connection.

[0036] By covering the buckle wall 112 of the slip buckle 11 with the anti-slip component 121, the first anti-slip part 122 of the anti-slip component 121 directly contacts the buckle wall 112 of the slip buckle 11, suppressing the twisting of the slip buckle 11 caused by uneven force; the anti-slip component 121 is connected to the external strap 200 to restrict the sliding of the external strap 200, thereby forming a friction control layer between the slip buckle 11 and the external strap 200, thereby optimizing the force transmission path and improving the stability of the protective gear.

[0037] In operation, the outer strap 200, such as the elastic band 22, passes through the through hole 111 of the sliding buckle 11. The anti-slip element 121 covers the surface of the sliding buckle 11, and the first anti-slip part 122 contacts the surface of the sliding buckle 11, increasing the friction between the sliding buckle 11 and the anti-slip element 121. The side of the anti-slip element 121 facing away from the buckle wall 112 is connected to the outer strap 200, restricting the sliding of the outer strap 200 relative to the sliding buckle 11. This structural design makes it difficult for the sliding buckle 11 to twist or deflect under force, maintaining stable contact between the sliding buckle 11 and the outer strap 200, and improving the efficiency of force transmission.

[0038] The anti-slip component 121 can cover all the buckle walls 112 of the sliding buckle 11, or it can only cover one buckle wall 112 of the sliding buckle 11. For example, it can cover the surface of one buckle wall 112 of the sliding buckle 11, keeping the surface of the other buckle wall 112 smooth. When the outer strap 200 is set as an elastic band 22 and a tension band 23, the elastic band 22 is connected and fixed to the anti-slip component 121 covering one side of the buckle wall 112 of the sliding buckle 11. The first anti-slip part 122 on the anti-slip component 121 generates a large friction force, effectively preventing the elastic band 22 from slipping relative to the sliding buckle 11 during use. At the same time, the tension band 23 is attached to the other side of the buckle 11 where the anti-slip component 121 is not provided, forming a low-friction sliding channel. This asymmetrical structural design realizes functional partitioning, with high friction on one side for fixing the elastic band 22 and low friction on the other side for smooth adjustment of the tension band 23. This ensures a clear and efficient force transmission path, significantly improving the smoothness of adjustment and operational efficiency. At the same time, it suppresses the torsion of the sliding buckle 11 due to force eccentricity, enhancing the overall structural stability and user experience.

[0039] The anti-slip buckle structure 10 provided in this application embodiment, compared with the prior art, increases the friction between the anti-slip member 121 and the buckle 11 by providing an anti-slip member 121. The anti-slip member 121 covers at least one buckle wall 112 of the buckle 11, and the first anti-slip part 122 on the anti-slip member 121 contacts the buckle wall 112. The outer strap 200 passes through the through hole 111 of the buckle 11 and connects to the side of the anti-slip member 121 facing away from the buckle wall 112, thereby restricting the sliding of the outer strap 200 relative to the buckle 11 and keeping the buckle 11 stable under force. Furthermore, the stability of the buckle 11's posture also improves the overall symmetry and comfort of the protective gear, enhancing the user experience of the product.

[0040] In some embodiments of this application, the first anti-slip part 122 includes a plurality of anti-slip particles, which are spaced apart on the side of the anti-slip member 121 that contacts the buckle wall 112.

[0041] Anti-slip particles are distributed in a dotted structure on the side of the anti-slip part 121 that contacts the buckle wall 112. The contact points, whether discrete or uniform, increase the frictional resistance. When the buckle 11 is under force, the load is dispersed through multi-point contact, preventing the buckle 11 from deflecting.

[0042] The anti-slip particles can be made of materials such as silicone, rubber, or latex, and can be fixed to the anti-slip part 121 by hot pressing or screen printing. By designing the anti-slip particles, the contact stability between the anti-slip part 121 and the buckle wall 112 of the sliding buckle 11 is improved, and the force transmission efficiency is reduced due to the deflection of the sliding buckle 11 relative to the external strap 200.

[0043] Please refer to some embodiments of this application. Figure 2The first anti-slip part 122 includes a plurality of anti-slip strips 1221, which are spaced apart on the side of the anti-slip member 121 that contacts the buckle wall 112.

[0044] Anti-slip strips 1221 are spaced apart on the side of the anti-slip member 121 that contacts the buckle wall 112. The spacing can be either an array or a discrete distribution, forming a linear contact area and increasing the friction area. In some embodiments, the anti-slip strips 1221 extend along the length of the buckle 11, and multiple anti-slip strips 1221 are spaced apart along the width of the buckle 11 on the side of the anti-slip member 121 that contacts the buckle wall 112. The length direction Y of the buckle 11 refers to the direction of its long side, and the width direction X of the buckle 11 refers to the direction of its short side.

[0045] When the external strap 200, such as the tension belt 23, moves, the anti-slip strip 1221 provides directional frictional resistance through its strip-shaped anti-slip structure, thus maintaining the stability of the sliding buckle 11.

[0046] The anti-slip strip 1221 can be made of materials such as silicone, rubber, or latex, and can be fixed to the anti-slip component 121 by bonding, hot pressing, or screen printing. The anti-slip strip 1221 can also be formed by stacking multiple small anti-slip segments along the length Y or width X direction of the sliding buckle 11 (e.g., ...). Figure 2 (As shown).

[0047] In some embodiments of this application, the first anti-slip part 122 includes an anti-slip layer connected to the side of the anti-slip member 121 that contacts the buckle wall 112.

[0048] An anti-slip layer covers the side of the anti-slip component 121 that contacts the buckle wall 112, forming a continuous friction surface that provides a better anti-slip effect. Specifically, silicone or rubber materials can be used to completely cover the side of the anti-slip component 121 that contacts the buckle wall 112, thereby enhancing the coefficient of friction through the viscoelasticity of the material itself.

[0049] The anti-slip layer can be fixed to the side of the anti-slip part 121 that contacts the buckle wall 112 by hot pressing, or it can be integrally formed with the surface of the anti-slip part 121 by injection molding.

[0050] In some embodiments of this application, the first anti-slip part 122 includes raised anti-slip texture, which is provided on the side of the anti-slip member 121 that contacts the buckle wall 112.

[0051] The anti-slip texture can be applied to the side of the anti-slip component 121 that contacts the buckle wall 112 by surface embossing or printing. The specific shape of the anti-slip texture can be a grid, diamond pattern, serrated pattern, etc. The anti-slip texture, through its regularly or randomly distributed raised structure, creates a micro-interlocking effect when the buckle 11 contacts the anti-slip component 121.

[0052] The anti-slip texture forms a micro-rough surface through its uneven structure, enhancing surface friction performance. The anti-slip texture can be made of materials such as silicone, rubber, or latex. In some embodiments, the anti-slip texture is made of rubber and is distributed in a grid pattern on the side of the anti-slip member 121 that contacts the buckle wall 112.

[0053] By setting the first anti-slip part 122, the friction between the anti-slip part 121 and the surface of the buckle wall 112 of the sliding buckle 11 is increased, the fixing effect between the anti-slip part 121 and the sliding buckle 11 is enhanced, the sliding buckle 11 is prevented from twisting or deflecting during use, and the contact surface between the sliding buckle 11 and the external strap 200 (elastic strap 22, tension strap 23, etc.) is kept in an ideal state, thereby improving the overall symmetry and comfort of the protective gear and improving the user experience of the product.

[0054] In some embodiments, a second anti-slip portion (not shown) may be provided on the side of the anti-slip member 121 facing away from the buckle wall 112, forming a double-sided anti-slip structure with the first anti-slip portion 122. The first anti-slip portion 122 and the second anti-slip portion act on the surface of the slip buckle 11 and the contact surface of the outer strap 200, respectively. Providing the second anti-slip portion can increase the friction with the outer strap 200, thereby enhancing the stability of the anti-slip buckle structure 10. The second anti-slip portion may include granular protrusions, striped protrusions, anti-slip textures, or continuously covered anti-slip coating dots, and its material may be the same as or different from that of the first anti-slip portion 122.

[0055] As a result, the sliding of the outer strap 200 relative to the slip buckle 11 is further restricted, improving the overall anti-slip effect of the anti-slip buckle structure 10.

[0056] In some embodiments of this application, the material of the first anti-slip part 122 is silicone, rubber or latex.

[0057] The first anti-slip part 122 can be made of high friction elastic materials such as silicone, rubber or latex, which can significantly increase the static friction between the anti-slip part 121 and the outer surface of the sliding buckle 11, effectively preventing the anti-slip part 121 from sliding or shifting during use, thereby keeping the external strap 200 connected to the anti-slip part 121 stable relative to the sliding buckle 11.

[0058] Silicone material possesses excellent wear resistance, aging resistance, and biocompatibility, making it suitable for protective gear products used close to the skin for extended periods. Rubber, on the other hand, has a high coefficient of friction and tear resistance, ensuring stable fixation of the anti-slip component 121. Latex material has excellent elasticity and flexibility, allowing it to better conform to the minor unevenness on the surface of the clip 11 wall 112, increasing the actual contact area and thus enhancing friction.

[0059] By selecting the above materials, the friction between the anti-slip component 121 and the surface of the buckle wall 112 of the sliding buckle 11 is improved. The anti-slip component 121 can fit more firmly into the buckle wall 112 of the sliding buckle 11, reducing the twisting or deflection of the sliding buckle 11 during use, and improving the reliability of the structure and the smoothness of operation.

[0060] Please refer to some embodiments of this application. Figure 2 The anti-slip component 121 is made of fabric.

[0061] The fabric material has good flexibility and abrasion resistance, which can better cover the buckle wall 112 of the sliding buckle 11. Specifically, nylon, polyester or cotton fabric materials can be used.

[0062] The fabric's flexibility allows the anti-slip component 121 to adapt to deformation and bend, reducing the feeling of foreign objects during use. The fabric material also has good breathability and comfort, which can enhance the overall wearing experience of the protective gear.

[0063] Furthermore, the fabric itself has a microscopic rough surface, which can increase friction and maintain an anti-slip effect relative to the buckle wall 112. In addition, the external strap 200 can also be directly sewn onto the side of the anti-slip part 121 away from the buckle wall 112, which facilitates connection and maintains a long-term stable anti-slip effect. The first anti-slip part 122 or the second anti-slip part can be formed on the anti-slip part 121 by heat pressing or screen printing.

[0064] In some embodiments of this application, after one end of the anti-slip member 121 passes through the through hole 111, it is fixedly connected to the other end of the anti-slip member 121 by stitching to cover the buckle wall 112.

[0065] The anti-slip component 121 adopts a closed-loop fixing method. The free end of the anti-slip component 121 after passing through the through hole 111 is stitched to the other free end to form a closed structure, so as to completely cover at least one buckle wall 112 of the sliding buckle 11. When the two ends of the anti-slip component 121 are fixedly connected, the closed-loop structure forms a uniform covering pressure on the surface of the sliding buckle 11. In addition, one end of the anti-slip component 121 can be designed as a thin strip to facilitate passing through the through hole 111.

[0066] During the sliding process of the external strap 200 under force, the friction force between the anti-slip component 121 and the sliding buckle 11 is transformed into a constraint force through the closed-loop structure, preventing the anti-slip component 121 from being displaced along the sliding buckle 11.

[0067] The anti-slip component 121 is connected at both ends by sewing, which is simple to install and provides high connection strength and durability, effectively preventing loosening during use. In addition, the sewing process is mature and low in cost, and the sewing position and density can be flexibly adjusted as needed, achieving a stable connection of the anti-slip component 121 on the sliding buckle 11, providing a stable foundation for the subsequent function of the first anti-slip part 122.

[0068] Please refer to some embodiments of this application. Figure 3 One end of the anti-slip member 121 passes through the through hole 111 and is connected to the other end of the anti-slip member 121 to cover the buckle wall 112. At least one end of the anti-slip member 121 is provided with a connecting part 1211, which is used to fix and connect with the external strap 200.

[0069] One end of the anti-slip component 121 passes through the through hole 111 of the slide buckle 11 and connects to the other end of the anti-slip component 121, forming a ring structure that covers the surface of the slide buckle 11. The connection method can be a detachable connection, such as a snap connection or Velcro fastening; or a fixed connection, such as an adhesive connection or a sewn connection.

[0070] After the two ends of the anti-slip component 121 are fixed to each other, a connecting part 1211 is provided on at least one end. The connecting part 1211 can be extended from the anti-slip component 121 and form an integral structure with the anti-slip component 121.

[0071] By providing a connecting part 1211 for fixed connection with the external strap 200, the anti-slip component 121 and the external strap 200 can be relatively fixed, further anchoring the external strap 200 as a whole onto the anti-slip component 121. The friction between the first anti-slip part 122 and the sliding buckle 11 effectively prevents the external strap 200 from slipping, circumferentially twisting, or tilting relative to the sliding buckle 11 during use. Especially in scenarios where the tension band 23 is frequently adjusted, the connecting part 1211 can distribute the force, avoiding stress concentration in the through hole 111 area, thereby improving the stability and durability of the structure.

[0072] Please see Figures 1 to 5 This application provides a waist support belt 100, including a waist belt 20 and an anti-slip buckle structure 10 as described above, the anti-slip buckle structure 10 being connected to the waist belt 20.

[0073] There are various types of waist belts 20, and the elastic bands 22 on them also come in various forms. The anti-slip buckle structure 10 can be installed in a suitable position depending on the type of waist belt 20 and the structure of the elastic band 22. For example, in a fully enclosed waist belt 20, the anti-slip buckle structure 10 is usually connected to the side or front of the elastic band 22; in a split waist belt 20, where the left and right elastic bands 22 are connected in the middle, the anti-slip buckle structure 10 is usually placed on the side of the elastic band 22. Furthermore, the anti-slip buckle structures 10 can be used in pairs to achieve symmetrical compression.

[0074] The anti-slip buckle structure 10 utilizes its anti-slip function to reliably lock the elastic band 22 on the waist belt 20 and smoothly adjust the tension band 23, which not only improves the ease of use but also enhances the stability and safety of the waist support belt 100.

[0075] Please refer to some embodiments of this application. Figures 1 to 5 The waist belt 20 includes a main body 21, an elastic band 22 and a tension band 23. One end of the elastic band 22 is fixed to the main body 21, and the other end of the elastic band 22 passes through the through hole 111 of the sliding buckle 11 and is fixed to the main body 21. The elastic band 22 is fixedly connected to the anti-slip component 121. One end of the tension band 23 is fixed to the main body 21, and the other end of the tension band 23 passes through the through hole 111 of the sliding buckle 11 to form an adjustment end.

[0076] The main body 21 is the basic structure of the waist belt 20, and can be understood as excluding other parts such as the adjustment belt. The elastic band 22 is used to adjust the tightness of the main body 21 to accommodate different user body shapes. The tension band 23 is used to adjust the tension of the elastic band 22. The elastic band 22 is a resistance band, and the tension band 23 can be either a resistance band or a non-elastic band. Figure 5 Two sets of elastic bands 22 and tension bands 23 are symmetrically arranged on the left and right, and two anti-slip buckle structures 10 are also provided accordingly.

[0077] like Figure 4 Both ends of the elastic band 22 are fixed to the main body 21, forming a closed loop structure, and the sliding buckle 11 is threaded onto the elastic band 22. One end of the tension band 23 is fixed to the main body 21, and the other end passes through the sliding buckle 11 to form an adjustment end, which is free for the user to pull and adjust.

[0078] When the user pulls the adjustment end, the tension band 23 pulls the sliding buckle 11 and the elastic band 22, causing them to shift relative to the main body 21. Because the anti-slip part 121 and the elastic band 22 form an effective connection, the first anti-slip part 122 contacts the buckle wall 112 of the sliding buckle 11, generating high friction. This effectively prevents twisting or shifting between the elastic band 22 and the sliding buckle 11 during the adjustment process of the tension band 23, ensuring that the contact surfaces of the elastic band 22 and the sliding buckle 11 maintain a stable contact state. This allows the force applied by the tension band 23 to be evenly transmitted to the elastic band 22 through the sliding buckle 11, significantly reducing the tension required for adjustment. It also avoids abnormal compression of the elastic band 22 and tension band 23 by the end of the sliding buckle 11, maintaining symmetrical force on both sides of the waist support belt 100, and improving the evenness of the waist wrap and the stability of the support during wear.

[0079] In some embodiments, such as Figure 1-5The sliding buckle 11 is designed as a long strip structure with a through hole 111 in the middle; the anti-slip component 121 is designed as a sheet-like webbing with multiple latex threads distributed on its surface. The surface of the anti-slip component 121 with latex threads covers one buckle wall 112 of the sliding buckle 11, the elastic band 22 passes through the through hole 111 and is fixedly connected to the anti-slip component 121, and the tension band 23 passes through the through hole 111 and is attached to the other side wall of the sliding buckle 11. Thus, the elastic band 22 is fixed to the anti-slip part 121, and the first anti-slip part 122 contacts the buckle wall 112 of the sliding buckle 11 to generate high friction, which restricts the twisting tendency of the sliding buckle 11 during the adjustment of the tension band 23, so that the sliding buckle 11, the elastic band 22, and the tension band 23 always maintain a surface contact state, avoiding the interruption of the force transmission path caused by the sliding end of the sliding buckle 11 squeezing the external strap 200. The stability of the sliding buckle 11 is improved when the tension band 23 is adjusted, the operating pull is significantly reduced, the force distribution on both sides of the waist support belt 100 is more uniform, and the symmetry and comfort when wearing are improved.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
