Technical Field
[0001] This utility model relates to the field of rehabilitation products, and more specifically, to a lumbar support component. Background Technology
[0002] With changing lifestyles, prolonged desk work and study, along with poor posture, reduce muscle activity and impair blood circulation, leading to a rising incidence of lumbar diseases. Common lumbar conditions such as lumbar muscle strain and herniated discs cause significant pain and negatively impact quality of life. To alleviate lumbar symptoms and better protect the lower back, existing technology discloses a lumbar support structure that can be worn around the waist, with the tightness adjusted by pulling a cable on the support.
[0003] The inventors discovered during their research that existing lumbar support structures have at least the following drawbacks:
[0004] The cable is wrapped around the outer surface of the lumbar support body. The cable changes direction by multiple protrusions installed on the outer side of the lumbar support body. The cable and the protrusions are in sliding friction contact, resulting in high resistance when pulling, difficult adjustment, and low adjustment accuracy. Utility Model Content
[0005] The purpose of this utility model includes, for example, providing a lumbar support component that can reduce the resistance encountered when pulling the cable, has flexible and labor-saving adjustment operation, high adjustment accuracy, and a wide range of applications.
[0006] The embodiments of this utility model can be implemented as follows:
[0007] In a first aspect, this utility model provides a lumbar support component, comprising:
[0008] The lumbar support body, the lumbar support component, and the tension adjustment mechanism are provided. The lumbar support component is detachably connected to the inner side of the lumbar support body, and the side of the lumbar support component away from the lumbar support body is designed to fit against the human waist. The tension adjustment mechanism includes two positioning components and two sets of pulling units. The two positioning components are both installed on the side of the lumbar support body away from the lumbar support component.
[0009] Each of the pulling units includes a cable and multiple steering wheels, which are distributed on two positioning members. Each steering wheel is rotatably engaged with a positioning member. One end of each cable is fixedly connected to one of the two positioning members, and the other end passes through multiple steering wheels in the same group in sequence before slidingly connecting to the other of the two positioning members.
[0010] In an optional embodiment, each of the cables is secured with a handle at the end furthest from the positioning element.
[0011] Based on the above scheme, when it is necessary to adjust the tightness, the operator can hold the two handles at the ends of the two cables with both hands, which is not easy to slip, makes it convenient to apply force, saves more effort, and makes the adjustment operation more efficient and quick.
[0012] In an optional embodiment, the handle and the lumbar support body are detachably coupled via a Velcro assembly.
[0013] Based on the above solution, once the length of the cable is adjusted, that is, after the tightness of the waist support body is adjusted, the handle is attached to the appropriate position on the waist support body using the Velcro assembly. The cable is not easy to come loose automatically and can always be kept at the set length, resulting in good waist support effect.
[0014] In an optional embodiment, the positioning element includes a positioning plate and a plurality of mounting seats fixed to the positioning plate, each of the mounting seats cooperating with the positioning plate to define a mounting cavity, and the steering wheel is rotatably mounted in the mounting cavity.
[0015] Based on the above scheme, the directional wheel is positioned inside the mounting cavity, and the position of the directional wheel is stable and reliable, thereby improving the stability of the cable.
[0016] In an optional embodiment, the positioning member is provided with a plurality of first slots, each of the first slots being disposed opposite to a corresponding mounting base;
[0017] The mounting base has a first side and a second side opposite to each other in the arrangement direction of the two positioning members. The first side is provided with a mounting port and a second slot communicating with the mounting port. The two ends of the axle of the steering wheel are respectively engaged in the first slot and the second slot.
[0018] Based on the above scheme, the directional wheel is inserted into the mounting cavity from the first side, and the two ends of the directional wheel axle are respectively inserted into the first slot and the second slot. The bottom walls of the first slot and the second slot restrict the position of the axle, ensuring that the axle can rotate stably.
[0019] In an optional embodiment, the second side of the mounting base is provided with two wire holes, and the cable is sequentially threaded through the two wire holes.
[0020] Based on the above scheme, the cable is threaded through two wire holes. The cable is positioned by the wire holes and is not easy to slip off the adjusting wheel, making the tension adjustment more reliable.
[0021] In an optional embodiment, two elastic strips are provided on the side where the lumbar support body connects to the lumbar support pad.
[0022] Based on the above solution, two elastic strips are used to enhance the side support of the lumbar support body, thereby making the lumbar support body fit more closely to the human waist and improving the lumbar support effect.
[0023] In an optional embodiment, the lumbar support assembly further includes a wear-resistant plate, which is installed on the side of the lumbar support body away from the lumbar support member. The wear-resistant plate is provided with multiple grooves for receiving wires, and the cable passes through the multiple grooves for receiving wires in sequence.
[0024] Based on the above solution, when adjusting the tension of the cable, the cable contacts the wear-resistant plate, and the cable does not easily come into direct contact with the main body of the lumbar support, thus preventing wear on the main body of the lumbar support.
[0025] In an optional embodiment, the lumbar support is configured as a support pad or a support plate.
[0026] Based on the above solution, lumbar support components can be selected as needed, allowing for flexible use.
[0027] In an optional embodiment, when the lumbar support is configured as a support pad, the support pad is provided with a plurality of massage protrusions for contacting the human lumbar region.
[0028] Based on the above design, the massage protrusions come into contact with the waist, providing not only waist support but also massage, thus enhancing comfort.
[0029] The beneficial effects of this utility model embodiment include, for example:
[0030] In summary, the lumbar support component provided in this embodiment uses cables supported and guided by multiple directional rollers. When it is necessary to adjust the tightness of the lumbar support body, the free ends of two cables are pulled simultaneously, that is, the ends of the two cables not connected to the positioning components are pulled at the same time. When the cables slide relative to the directional rollers, they drive the directional rollers to rotate. In this way, there is rolling friction between the cables and the directional rollers, resulting in low friction and low resistance to the cables. Pulling the cables is less strenuous, the adjustment operation is more convenient, and the tightness can be controlled more accurately, improving the adjustment precision. This allows the lumbar support body to achieve the optimal lumbar support state and improve the comfort of use. Attached Figure Description

[0045] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0046] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0047] Please refer to Figures 1-7 This embodiment provides a lumbar support component, including a lumbar support body 100, a lumbar support member 200, and a tension adjustment mechanism 300. The lumbar support member 200 is detachably connected to the inner side of the lumbar support body 100, and the side of the lumbar support member 200 away from the lumbar support body 100 is designed to fit against the human waist; the tension adjustment mechanism 300 includes two positioning members 310 and two sets of pulling units 320, and both positioning members 310 are installed on the side of the lumbar support body 100 away from the lumbar support member 200. Each set of pulling units 320 includes a cable 321 and multiple directional rollers 322. The multiple directional rollers 322 are distributed on two positioning members 310, and each directional roller 322 is rotatably engaged with a positioning member 310. One end of each cable 321 is fixedly connected to one of the two positioning members 310, and the other end passes through multiple directional rollers in the same set in sequence and is slidably connected to the other positioning member 310.
[0048] As described above, the lumbar support component provided in this embodiment can be used in the following ways, for example:
[0049] First, attach the lumbar support component 200 to the inner side of the lumbar support body 100 using Velcro, ensuring the height of the lumbar support component 200 is appropriate. Then, place the lumbar support component 200 against the waist, bringing the two sides of the lumbar support body 100 together and securing them with Velcro, thus positioning the lumbar support body 100 around the waist and simultaneously positioning the lumbar support component 200. Next, hold the free ends of the two cables 321 with both hands and pull them, bringing the two positioning pieces 310 closer together, adjusting the tightness of the lumbar support body 100. After adjustment, secure the cables 321 to the lumbar support body 100, ensuring the cables 321 are secure and that the lumbar support body 100 provides stable and consistent support, improving the lumbar support effect.
[0050] It should be understood that the pull cables 321 are supported and guided by multiple adjusting wheels 322. When it is necessary to adjust the tightness of the lumbar support body 100, the free ends of both pull cables 321 are pulled simultaneously. As the pull cables 321 slide relative to the adjusting wheels 322, they drive the adjusting wheels 322 to rotate. In this way, there is rolling friction between the pull cables 321 and the adjusting wheels 322, resulting in low friction and low resistance on the pull cables 321. Pulling the pull cables 321 is less strenuous, the adjustment operation is more convenient, and the tightness can be controlled more accurately, improving the adjustment precision. This allows the lumbar support body 100 to achieve the optimal lumbar support state and improve the comfort of use. Because the sliding of both pull cables 321 is very smooth and silky, and the sliding synchronization of the two pull cables 321 is high, the force is evenly distributed on both sides of the lumbar support body 100, resulting in high adjustment quality.
[0051] The following embodiments illustrate the detailed structure of the lumbar support component of this application by way of example.
[0052] Please refer to Figure 1 In this embodiment, optionally, a handle 323 is fixed to the end of each cable 321 away from the positioning member 310. When it is necessary to adjust the tension, the operator can hold the two handles 323 at the ends of the two cables 321 with both hands respectively. This makes it less likely to slip, easier to apply force, less strenuous, and more efficient and quick to adjust.
[0053] Optionally, the handle 323 can be detachably attached to the lumbar support body 100 via a Velcro assembly.
[0054] It should be understood that after the length of the cable 321 is adjusted, that is, after the tightness of the waist support body 100 around the waist is adjusted, the handle 323 is attached to the appropriate position on the waist support body 100 using the Velcro assembly. The cable 321 is not easy to come loose automatically and can always stay at the set length, resulting in a good waist support effect.
[0055] It should be noted that the handle 323 has an inner hole for fingers to pass through. The inner hole is an arc-shaped hole, and the diameter of the inner hole gradually changes from one side to the other. Specifically, the inner hole has a larger diameter on the side away from the cable 321. This side allows fingers to pass through without squeezing them, making operation more comfortable.
[0056] Please refer to Figures 1-3 In this embodiment, optionally, the positioning member 310 includes a positioning plate and a plurality of mounting seats 312 fixed on the positioning plate. Each mounting seat 312 cooperates with the positioning plate to define a mounting cavity 315, and the directional wheel 322 is rotatably mounted in the mounting cavity 315. The directional wheel 322 is positioned in the mounting cavity 315, and the position of the directional wheel 322 is stable and reliable, thereby improving the stability of the cable 321.
[0057] It should be understood that four mounting seats 312 can be provided on each positioning plate. The same cable 321 cooperates with the four mounting seats 312 located on the two positioning plates respectively. Each mounting seat 312 is equipped with a directional wheel 322. In this way, each cable 321 passes around the four directional wheels 322 in sequence.
[0058] Optionally, the positioning element 310 is provided with multiple first slots 313, each first slot 313 being opposite to a corresponding mounting base 312. When the number of mounting bases 312 is eight, each positioning strip 311 is provided with four first slots 313, and a total of four first slots 313 are designed on the two positioning strips 311. The mounting base 312 has a first side and a second side opposite to each other in the arrangement direction of the two positioning elements 310. The first side is provided with a mounting opening and a second slot 314 connecting the mounting opening; the two ends of the axle of the directional wheel 322 are respectively engaged in the first slot 313 and the second slot 314.
[0059] In this way, the directional wheel 322 is inserted into the mounting cavity 315 from the first side, and the two ends of the axle of the directional wheel 322 are respectively inserted into the first slot 313 and the second slot 314. The bottom wall of the first slot 313 and the second slot 314 restricts the position of the axle, ensuring that the axle can rotate stably.
[0060] Furthermore, the second side of the mounting base 312 is provided with two wire holes 316, and the cable 321 is sequentially threaded through the two wire holes 316. With the cable 321 threaded through the two wire holes 316, the cable 321 is positioned by the wire holes 316, making it less likely to slip off the adjusting wheel 322, and the tension adjustment is more reliable.
[0061] Optionally, in order to ensure the tight fit between the cable 321 and the directional wheel 322 and to prevent the cable 321 from slipping off the directional wheel 322, an annular positioning groove is provided on the outer circumferential surface of the directional wheel 322, and the cable 321 is wound around the annular positioning groove.
[0062] Furthermore, each positioning bar 311 is also provided with a positioning lug 317, and two cables 321 are respectively threaded through the corresponding positioning lug 317. After the cable 321 is led out from the outermost directional wheel 322 and threaded through the positioning lug 317, the positioning lug 321 is positioned by the positioning lug 317, and the position of the cable 321 and the directional wheel 322 is more stable.
[0063] Please refer to Figure 3 In this embodiment, optionally, two elastic strips 500 are provided on the side where the lumbar support body 100 connects to the lumbar support pad. The two elastic strips 500 enhance the side support of the lumbar support body 100, thereby making the lumbar support body 100 fit more closely to the waist and improving the lumbar support effect.
[0064] It should be understood that the elastic strip 500 can be fixed to the lumbar support body 100 by means of sewing or other methods.
[0065] In addition, the outer side of the lumbar support body 100 is provided with a hand strap 110, in which the operator's hands can be inserted to make it easy to surround the two sides of the lumbar support body 100.
[0066] Please refer to Figure 1 and Figure 4 In this embodiment, optionally, the lumbar support component also includes a wear-resistant plate 400. The wear-resistant plate 400 is installed on the side of the lumbar support body 100 away from the lumbar support member 200. The wear-resistant plate 400 is provided with multiple grooves 410 for receiving wires, and the cable 321 is sequentially passed through the multiple grooves 410 for receiving wires. When adjusting the tension of the cable 321, the cable 321 contacts the wear-resistant plate 400, and the cable 321 does not easily come into direct contact with the lumbar support body 100, thus preventing wear on the lumbar support body 100.
[0067] Please refer to Figures 6-7 In this embodiment, the lumbar support 200 can optionally be configured as a support pad or a support plate. The lumbar support 200 can be selected as needed, providing flexibility in its use.
[0068] Optionally, when the lumbar support 200 is configured as a support pad, the support pad is provided with multiple massage protrusions 210 for contact with the human lumbar region. The massage protrusions 210, in contact with the human lumbar region, not only provide lumbar support but also massage, thereby improving comfort.
[0069] In addition, when the lumbar support component 200 is set as a support plate, the support plate can be made of polymer material, which has a good manufacturing effect, and the curvature of the support plate is more in line with the curve of the human waist, fits the waist better, and has a good support effect.
[0070] The lumbar support component provided in this embodiment has a rolling contact between the cable 321 and the directional wheel 322, resulting in low friction, smoother and more flexible operation, and less likelihood of jamming. The lumbar support body 100 is evenly stressed on both sides, and the lumbar support body 100 fits more tightly with the waist, improving the lumbar support effect.
[0071] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
