Description

Technical Field

[0001] This utility model relates to the field of lumbar support belt technology, and in particular to a lumbar support belt with a pressure-applying structure. Background Technology

[0002] In existing technologies, lumbar supports, as wearable devices used to protect the lower back and spine, have been widely used in medical rehabilitation, sports protection, and workplace injury prevention. Their core design concept is to apply appropriate physical pressure and support to the lower back, limiting excessive flexion, extension, lateral bending, and rotation of the lumbar spine, thereby alleviating or preventing common lower back problems such as lumbar muscle strain, herniated discs, and degenerative lumbar spine diseases. Traditional lumbar supports often use a structure combining synthetic fibers (such as nylon and polyester) with elastic bands, with Velcro closures at both ends for adjustment. Several rigid or semi-rigid support plates, support strips, or fiber sheets are often embedded inside or near the body to provide necessary support. This type of design can compensate for pressure on the lower back to a certain extent, reducing the load on the lumbar spine.

[0003] Chinese patent CN 218605199 U discloses a lumbar support belt, comprising: a belt body, a support strip, and two support plates. The support strip is located on the side of the belt body closest to the body and in the middle of the belt body, with its length direction perpendicular to the length direction of the belt body. The two support plates are located on either side of the support strip's length direction, with a gap between the support strip and the support plates. This invention, by setting a support strip in the middle of the belt body, with its length direction aligned with the width direction of the belt, allows the support strip to conform to the lumbar spine during wear, facilitating support for the lumbar spine. The support plates on both sides of the support strip protect the lower back on both sides of the lumbar spine. The gap between the two support plates and the support strip provides deformation space, conforming to the curvature of the waist and reducing gaps between the support strip / plates and the waist, thus allowing the belt to better fit the body and protect the lumbar spine. Although CN218605199U has made some improvements in fit design compared to traditional flat lumbar supports, the support components in this solution are still mainly rigid strips, which cannot form three-dimensional pressure in multiple directions. The support force is only transmitted along the vertical direction of the plane, and the tightness of the waist belt can only be achieved by tightening the Velcro as a whole. It is impossible to achieve zoned pressure or dynamic adjustment in different sections of the waist, making it difficult for users to obtain a flexible and stable fit.

[0004] Therefore, how to meet the demand for precise, adjustable, and all-round pressure support for the waist, and resolve the functional degradation and discomfort caused by long-term wear, remains a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a waist support belt with a pressure structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lumbar support belt with a pressure-adjusting structure, comprising:

[0008] A waist support, used to wrap around the waist;

[0009] The first connecting part is provided at both ends of the waist support and is used to initially fix the waist support to the waist of the human body;

[0010] A pair of support members are located on the side of the lumbar support away from the waist and in the middle of the lumbar support.

[0011] A pair of restraint straps, one end of each restraint strap is connected to the waist support, and the other end is connected to the first connecting part or the second connecting part of one end of the other restraint strap through a second connecting part provided on the restraint strap. A through slot is provided on each restraint strap. The two restraint straps are arranged in a cross shape, and the end of one restraint strap away from the support passes through the through slot of the other restraint strap and is connected to the first connecting part.

[0012] In one example of this application, the lumbar support includes two mounting portions and a third connecting portion, the third connecting portion being arranged in a stretchable and elastic manner between the two mounting portions.

[0013] In one example of this application, the support is fixedly connected to the surface of the mounting portion near the third connection portion by means of sewing or adhesive.

[0014] In one example of this application, the restraint strap includes a restraint member fixedly connected to one of the mounting parts, a limiting buckle installed on the end of the restraint member away from the support member, and a tightening adjustment member slidably connected to the limiting buckle. The tightening adjustment member can adjust the connection position of the limiting buckle to adjust the tightness of the restraint strap.

[0015] In one example of this application, in each of the restraint straps, the restraint member is mounted on one of the mounting portions, the other end of the restraint member extends beyond the support on that mounting portion and toward another mounting portion, and the tightening adjustment member is mounted on the other mounting portion.

[0016] In one example of this application, the restraint includes a pressing body, one end of which is fixedly connected to the mounting part and the other end is fixedly connected to the limiting buckle, and the through slot is provided on the pressing body.

[0017] In one example of this application, the pressing body is arranged in a tapering shape from the fourth connecting part away from the limiting buckle to the fifth connecting part closer to the limiting buckle, and the through slot is arranged in a triangular shape with a tapering shape from the fourth connecting part to the fifth connecting part.

[0018] In one example of this application, the limiting buckle includes a sliding buckle body, on which a first connecting groove is provided. One end of the tightening adjustment member is a fixed end, which is fixed to the side of the mounting part away from the support member, and the other end is an adjustment end. After passing through the first connecting groove, the adjustment end is folded back to the side of the mounting part away from the support member. A second connecting part is provided at the adjustment end.

[0019] In one example of this application, both the mounting part and the tightening adjustment part are integrally molded from elastic fabric.

[0020] In one example of this application, both the first connecting part and the second connecting part adopt a Velcro structure.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The lumbar support belt with a pressure structure described in this application adapts to different waist sizes and provides primary fixation by setting retractable mounting parts on both sides of the lumbar support and a third connecting part in the middle. The support component is combined with the mounting part by sewing or gluing to achieve basic support for the lumbar spine. The cross-interlacing of two restraint straps is guided by pressing the main body and the triangular tapered through-hole, and combined with the sliding locking of the limit buckle and tightening adjustment component, a multi-directional, zoned and adjustable secondary pressure support is formed. At the same time, relying on the wedge effect of the triangular through-hole and the adaptive expansion and contraction function of the elastic one-piece molded material, it maintains continuous tension and close fit on the front, back and sides of the waist. This structure not only significantly improves the fit and support stability of the waist during work, but also improves the durability of the components by simplifying the wearing process, enhancing the convenience and comfort of use, and effectively avoiding the problems of local overpressure, loosening and displacement, and discomfort caused by long-term wear caused by traditional one-way tension design. Thus, it achieves refined, adjustable and all-round support for the waist. Attached Figure Description

[0031] Reference Figures 1-3This application discloses a lumbar support belt with a pressure structure, including a lumbar support 1. Both ends of the lumbar support 1 are connected to first connecting parts 2. When the lumbar support 1 is wrapped around and bound to the waist of a person, the first connecting parts 2 at both ends of the lumbar support 1 are connected to each other. A pair of support members 7 and a pair of binding straps 3 are provided on the side of the lumbar support 1 away from the waist. The support members 7 are located near the middle of the lumbar support 1. One end of each binding strap 3 is connected to the lumbar support 1, and the other end is connected to the first connecting part 2 or the second connecting part 4 of another binding strap 3 through a second connecting part 4 provided on the binding strap 3. A slot 804 is provided on each binding strap 3. The two binding straps 3 are arranged in a crisscross pattern, with one binding strap 3 passing over the support member 7 and through the slot 804 of the other binding strap 3. When the lumbar support 1 is wrapped around and bound to the waist of a person, the two binding straps 3 cross and press against the support member 7, connecting to the lumbar support 1. In the example of this application, both the first connecting part 2 and the second connecting part 4 adopt a Velcro structure.

[0032] The lumbar support belt with a pressure-applying structure disclosed in this application includes a lumbar support 1 that can be wrapped around the waist. Both ends of the lumbar support 1 are provided with Velcro fasteners for initial fixation to the user's waist. A pair of support members 7 are provided in the middle of the side of the lumbar support 1 away from the waist. Two binding straps 3 form a cross structure. One end of each binding strap 3 is connected to the lumbar support 1, and the other end can be connected to a first connecting part 2 at the end of the lumbar support 1 via its own Velcro fastener, or to another second connecting part 4. For example, the two ends of the lumbar support 1 can be glued together first, then one of the second connecting parts 4 can be glued to the first connecting part 2, and then the other second connecting part 4 can be glued to the first connecting part 2 or the aforementioned second connecting part 4. Simultaneously, one binding strap 3 passes through the slot 804 of the other binding strap 3 to achieve cross-pressure. With this cross-structure, the user can flexibly adjust the tightness of the binding straps 3 and achieve a symmetrical pressure distribution. When worn, the cross-force of the binding straps 3 establishes stable pressure support in the front, back, and sides of the waist, effectively enhancing the fit and stability of the lumbar support belt.

[0033] The lumbar support belt with pressure structure described in this application differs from the traditional unidirectional tension design, which can simultaneously form stable pressure support on the front, back, and sides of the waist. This zoned pressure method allows for flexible adjustment of the belt tension according to the user's needs, effectively improving fit and preventing displacement. It also simplifies the wearing process and enhances the overall stability and comfort of the waist, better meeting the dual needs of waist protection and freedom of movement.

[0034] As a preferred example of this application, the lumbar support 1 includes two mounting portions 5 and a third connecting portion 6 connecting the two mounting portions 5, wherein the third connecting portion 6 is elastically extendable. In the example of this application, the lumbar support belt consists of the lumbar support 1, a first connecting portion 2, a support member 7, and a restraint strap 3, etc. The lumbar support 1 includes two mounting portions 5 surrounding both sides of the waist and a retractable third connecting portion 6 connecting the two mounting portions 5. The user can glue and fix the two mounting portions 5 to the front and back of the waist through the first connecting portion 2 and adjust the length of the third connecting portion 6 to adapt to different waist sizes, thereby improving the versatility and wearing comfort of the lumbar support belt.

[0035] As a preferred example of this application, the support member 7 is fixedly connected to the surface of the mounting part 5 near the third connecting part 6 by sewing or gluing. The combined design of the split mounting part 5 and the flexible third connecting part 6 retains the stability of the rigid support while mitigating the pulling sensation when bending over through the flexible connecting section in the middle. When the wearer leans forward, the flexible middle section naturally extends, while the rigid support members 7 on both sides still maintain the wrapping protection of the lumbar spine. The rigid connection structure between the support member 7 and the mounting part 5 can evenly transmit the pressure applied by the restraint strap 3 to both sides of the waist, avoiding the local pressure accumulation caused by insufficient overall rigidity in traditional lumbar supports. At the same time, the flexible middle connecting part alleviates the discomfort of the upper and lower edges of the lumbar support squeezing the ribcage and pelvis. When the body bends over or turns, the flexible middle connecting part can naturally deform with the movement, while the rigid support members 7 on both sides form an "anchoring zone" through the sewing fixing points. This rigid-flexible partitioning design does not restrict normal range of motion and ensures that the lumbar support does not shift or slip during exercise.

[0036] As a preferred example of this application, the restraint strap 3 includes a restraint member 8 fixedly connected to one of the mounting parts 5, a limiting buckle 9 installed on the restraint member 8 away from the fixed end, and a tightening adjustment member 10 slidably connected to the limiting buckle 9. The tightening adjustment member 10 can adjust the connection position of the limiting buckle 9 to adjust the tightness of the restraint strap 3. In the example of this application, the binding strap 3 consists of three parts: a binding member 8 is securely connected to the mounting part 5 near the support member 7, and the other end extends beyond the support member 7 to another mounting part 5 to form an outer end, providing a reliable pressing base for subsequent binding; a limiting buckle 9 is installed on the outer end of the binding member 8, and a sliding hole is provided on it to allow the tightening adjustment member 10 to slide through. One end of the tightening adjustment member 10 is connected to the waist support 1 through the mounting part 5, and the other end is provided with a second connecting part 4 with a Velcro structure. After passing through the limiting buckle 9, the second connecting part 4 is attached to the first connecting part 2 at the end of the waist support 1, or to another second connecting part 4, so that the binding strap 3 can slide freely along the guide rail of the limiting buckle 9 when wrapped around the waist and achieve precise pressure adjustment. When in use, the user wraps the waist support 1 around the waist and then glues and fixes the two mounting parts 5 together through the first connecting part 2. The length of the third connecting part 6 is adjusted according to the waist circumference to obtain the initial tension. Then, the tightening adjustment parts 10 of the two binding straps 3 are passed out from the limit buckle 9 and bent in the opposite direction to fit and lock with the first connecting part 2 or another second connecting part 4. The distance that the binding part 8 and the limit buckle 9 are adjusted by the tightening adjustment part 10 determines the pressure. The binding part 8 and the tightening adjustment part 10 automatically expand and contract when the waist curve changes to maintain stable tension. The interlaced binding straps 3 apply uniform force to the waist in multiple directions at the same time.

[0037] The binding strap 3 described in this application achieves precise adjustment of the applied pressure through the sliding connection between the limiting buckle 9 and the tightening adjustment component 10. Combined with the elastic telescopic section or sliding positioning function, it can automatically conform to the waist curve and maintain tension continuously, thereby significantly improving the fit, support stability and wearing comfort of the waist support belt, and effectively preventing displacement and excessive local pressure.

[0038] As a preferred example of this application, the restraint member 8 includes a pressing body 801, one end of which is fixedly connected to the mounting part 5, and the other end is fixedly connected to the limiting buckle 9. The through slot 804 is disposed on the pressing body 801. As a specific example of this application, one end of the pressing body 801 is sewn to the mounting part 5 on the side of the support member 7 away from the third connecting part 6 via a fourth connecting part 802, and the other end is fixedly connected to the limiting buckle 9 via a fifth connecting part 803. The limiting buckle 9 can be locked and fixed by a tightening adjustment member 10 fixed on another mounting part 5. In use, the two restraint straps 3 are led out from the left and right mounting parts 5 respectively. After one restraint strap 3 passes through the through slot 804 of the other restraint strap 3, a cross-shaped restraint structure is formed. The tightening adjustment members 10 of the two restraint straps 3 are tightened and fixed by Velcro. This application adopts a structural design that combines the pressing body 801 with the through slot 804 to form two intersecting binding straps 3, which abandons the traditional one-way tightening method. It can form stable pressure support in multiple directions of the waist at the same time, which significantly improves the fit and support stability of the waist belt to the body, and effectively prevents the waist belt from shifting and becoming too loose or too tight in some areas while maintaining flexibility.

[0039] As a preferred example of this application, the pressing body 801 is arranged in a tapering cross-section from the fourth connecting portion 802 away from the limiting buckle 9 to the fifth connecting portion 803 near the limiting buckle 9. Preferably, the through slot 804 is triangular in design, and the through slot 804 is arranged in a tapering cross-section from the fourth connecting portion 802 away from the limiting buckle 9 to the fifth connecting portion 803 near the limiting buckle 9. The restraint member 8 disclosed in this application has a triangular through slot 804 on the pressing body 801. The through slot 804 gradually narrows from the fourth connecting part 802 away from the limiting buckle 9 to the fifth connecting part 803 closer to the limiting buckle 9. The pressing body 801 itself also has an arc-shaped tapering cross section in the same direction. This design allows the two restraint straps 3 to be accurately guided and closely conform to the waist curve when they cross and interlock. At the same time, this structure ensures the reliability of the end connection of the restraint member 8 and the pressing deformation, enhances the overall stability of the waist support belt for the waist, simplifies the wearing process, better meets the needs of waist protection and freedom of movement, and provides users with a more comfortable and effective waist support experience.

[0040] As a preferred example of this application, the limiting buckle 9 includes a sliding buckle body 901, on which a first connecting groove 902 is provided. The tightening adjustment member 10 is fixed to the mounting part 5 on the side away from the support member 7 via a fixed end 11, and the other end is set as an adjusting end 12. The adjusting end 12 passes through the first connecting groove 902 and then folds back to the side of the mounting part 5 away from the support member 7. The second connecting part 4 is provided on the adjusting end 12. When the waist support belt is wrapped around the waist, after the two ends of the waist support 1 are initially connected by the first connecting part 2, the tightening adjustment member 10 slides in the first connecting groove 902 by pulling the adjusting end 12, thereby adjusting the overall tightness of the binding belt 3. Then, the second connecting part 4 is connected and fixed to the corresponding connecting part to realize the pressure binding of the waist support belt on the waist. This setting further discloses a tightening adjustment member 10 including a fixed end 11 and an adjusting end 12, which, together with the first connecting groove 902 of the limiting buckle 9, allows the user to easily adjust the tightness of the binding belt 3 with one hand, improving the convenience of use. In the example of this application, a second connecting groove 903 is also provided on the sliding body 901, and the fifth connecting part 803 of the pressing body 801 is fixed in the second connecting groove 903.

[0041] As a preferred example of this application, both the lumbar support 1 and the tightening adjustment component 10 are integrally molded from elastic fabric. The lumbar support 1 and tightening adjustment component 10, both integrally molded from elastic fabric, allow the elastic fabric to automatically adjust its tightness according to the movement of the waist. While providing stable pressure support, it does not excessively restrict the waist, ensuring freedom of movement and giving the lumbar support belt good elasticity and fit. Furthermore, the integral molding design reduces the number of splices between components, lowers the risk of damage to the lumbar support belt, improves its durability, simplifies the manufacturing process, and makes the lumbar support belt more comfortable and convenient to wear.

[0042] As a preferred example of this application, both the mounting part 5 and the tightening adjustment member 10 are integrally molded from elastic fabric. For example, the mounting part 5 is made of knitted elastic cotton fabric, the third connecting part 6 is made of rubber sheet, the support member 7 is made of rigid silicone, achieving a support effect that is both rigid and flexible, and the restraint member 8 is made of nylon strap.

[0043] Compared to existing technologies, this application utilizes the lumbar support 1 and the binding strap 3 to achieve dual-level pressure on the waist. Combined with the support member 7, it provides excellent support for the waist. The combined design of the split mounting part 5 and the flexible third connecting part 6 retains the stability of the rigid support while mitigating the pulling sensation when bending over through the flexible connecting section in the middle. When the wearer leans forward, the flexible middle part naturally extends, while the rigid support members 7 on both sides still maintain the wrapping protection of the lumbar spine. The rigid connection structure between the support member 7 and the mounting part 5 can evenly transmit the pressure applied by the binding strap 3 to both sides of the waist, avoiding the localized pressure accumulation caused by insufficient overall rigidity in traditional lumbar supports. Meanwhile, the flexible connecting part in the middle alleviates the discomfort caused by the pressure of the upper and lower edges of the lumbar support on the ribcage and pelvis. When the body bends over or turns, the flexible connecting part in the middle can naturally deform with the movement, while the rigid support members 7 on both sides form "anchoring zones" through sewn fixing points. This rigid-flexible partition design does not restrict the normal range of motion, and ensures that the lumbar support does not shift or slip during exercise. In the restraint straps 3, two restraint straps 3 are led out from the left and right mounting parts 5 respectively. After one restraint strap 3 passes through the triangular slot 804 of the other restraint strap 3, it is adjusted by the buckle. Secured with Velcro, the two binding straps 3 intersect each other through the triangular slots 804. The beveled surface of the triangular slots 804 creates a wedge effect that tightens as it is pulled, preventing the straps from loosening or shifting even during vigorous activity. This ensures a stable wrap around the waist. The crossing angle evenly distributes pressure to the upper and lower edges of the waist support, avoiding edge lifting or localized marks caused by single-point force in traditional parallel straps. When bending over, the triangular slots allow for slight slippage of the straps, allowing them to naturally extend with waist movements without completely loosening. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
