[0047] Please refer to the atta Figure 1 - atta Figure 5 chment. This embodiment relates to a lumbar support belt, which is used to be bound around the outer periphery of the user's waist to provide support for the user's waist, thereby preventing or alleviating the user's waist injury.

[0048] Specifically, the lumbar support belt includes two belt linings arranged at intervals and a first adjustment assembly 1 and a second adjustment assembly 2 respectively installed on the two belt linings. Among them, the first adjustment assembly 1 includes a support shell 11, a mounting seat 12, a pulley group 13 and a pull rope 14. The support shell 11 includes a mounting portion 111 and a support portion 112 connected to the mounting portion 111. The mounting portion 111 is installed on the belt lining and forms a mounting cavity with the belt lining. The mounting cavity is provided with a first opening 113 and a second opening 114; the support portion 112 extends outward from the edge of the mounting portion 111 to support the user's lumbar and dorsal regions; the mounting seat 12 is arranged in the mounting cavity and forms a mounting space with the inner surface of the support shell 11; the pulley group 13 is arranged in the mounting space and is rotatably installed on the mounting seat 12; a part of the pull rope 14 is configured to connect the pulley group 13 and the second adjustment assembly 2 through the first opening 113, and another part is configured to extend out of the outside through the second opening 114 to form a control portion, and the control portion is configured to adjust the distance between the pulley group 13 and the second adjustment assembly 2 under the action of an external force.

[0049] In this embodiment, the second adjusting component 2 can adopt the same structural composition as the first adjusting component 1 and be arranged in parallel with the first adjusting component 1; of course, it can also adopt a structural composition different from that of the first adjusting component 1. Exemplarily, the number and arrangement of the pulleys of the second adjusting component 2 are different from those of the pulley set 13 of the first adjusting component 1.

[0050] In this embodiment, the support shell 11 is of a soft structure, and specifically, a plastic material with a certain flexibility can be adopted. The support shell 11 is a whole-piece structure, and a part of it forms the installation part 111 and extends outward from the edge of the installation part 111 to form the support part 112. The support part 112 is used to support and hold up the user's waist and back. The installation part 111 is rectangular, and a cuboid-shaped installation cavity is formed between it and the belt lining body. The first opening 113 and the second opening 114 are respectively arranged on the left and right sides of the installation cavity.

[0051] The mounting seat 12 is a plate-shaped part, covering the installation part 111, and an installation space for installing the pulley set 13 is formed between the two. At the same time, the mounting seat 12 is used to position the pulley set 13 to ensure reliable rotation of the pulley set 13 inside the installation space. The mounting seat 12 is of a rigid structure. Through the mounting seat 12, sufficient supporting force can be provided to the waist when the waist belt is in use. The setting of the pulley set 13 can make the pulling force of the user more labor-saving.

[0052] A part of the structure of the pull rope 14 is connected to the pulley set 13 and the second adjusting component 2 through the first opening 113. The pull rope 14 is wound around the pulley set 13 in the installation space, and after being led out through the first opening 113, it is connected to the second adjusting component 2; further, another part extends out of the outside world through the second opening 114 to form a control part. The user can hold the control part and pull the pull rope 14 outward, thereby shortening the distance between the pulley set 13 and the second adjusting component 2, and further making the first adjusting component 1 and the second adjusting component 2 of the whole waist belt close to clamp the user's waist, so that the whole waist belt is tightened to achieve the effect of supporting the waist.

[0053] The belt lining body can adopt a skin-friendly fabric with good air permeability, thereby enhancing air permeability and the comfort of being close to the body, effectively improving the user experience of the user. In this embodiment, the belt lining body can be connected to the support shell 11 by means of bonding, heat melting, partial embedding and sewing, etc.

[0054] Compared with the form of adding a support back plate and a pulley box to the lining body of the waist belt in the traditional prior art to realize the tightening and loosening of the waist belt, the structure of the waist belt in this embodiment is thinner and lighter; at the same time, compared with the external pulley box of the waist belt adopted in the prior art, this waist belt is more close to the body and invisible, improving the user experience.

[0055] Optionally, the support shell 11 is detachably connected to the mounting base 12.

[0056] In this embodiment, the support shell 11 can be provided with a buckle, and at the same time, a slot can be provided on the mounting base 12. Through the snap connection of the buckle and the slot, the detachable connection between the mounting base 12 and the support shell 11 is realized. Of course, in other embodiments, the support shell 11 and the mounting base 12 can also be connected by threaded fasteners, which can also achieve the effects of convenient assembly and reliable fixation.

[0057] Please refer to the attached Figure 3 and the attached Figure 4 and the attached Figure 6 and the attached Figure 7 Optionally, the support shell 11 includes a first side 115 and a second side 116 opposite to the first side 115. The first side 115 is close to the mounting base 12. The support shell 11 is a shelled structure, and the shelling depth of the support shell 11 gradually decreases along the direction from the first side 115 to the second side 116, so as to facilitate the elastic deformation of the support portion 112.

[0058] In this embodiment, the outer surface of the support shell 11 is a streamline structure. The overall support shell 11 is a shelled structure, forming a curved cover shape. In the direction from the first side 115 to the second side 116, the gradual decrease of the shelling depth makes the depth of the internal cavity of the support shell 11 gradually decrease, thereby ensuring that the elasticity of the support portion 112 gradually increases in this direction. In this embodiment, when the user uses this waist belt, it is wrapped around the waist on both sides of the back central axis. Among them, the user's back central axis and the areas near the central axis should require sufficient support to ensure the fixation and clamping of the waist, while the areas far from the central axis and close to the side waist only require appropriate support. However, in the area close to the side waist, a larger deformation of the waist belt is required. Therefore, this structure of the support shell 11 meets the user's different support force requirements for the support points of different parts of the waist.

[0059] Optionally, a plurality of deformation ventilation holes 117 are provided on the support portion 112 to facilitate the elastic deformation of the support portion 112.

[0060] In this embodiment, a plurality of deformation ventilation holes 117 are distributed on the support portion 112. The deformation ventilation holes 117 can be circular holes or other regular shapes or irregularly shaped holes. The present application does not make specific limitations on the shape of the deformation ventilation holes 117. The deformation ventilation holes 117 can improve the breathability of this waist belt. At the same time, the hollow structure of the deformation ventilation holes 117 can also reduce the weight of the support shell 11, ensure that the entire waist belt is lighter in weight, and improve the user's experience; in addition, on the premise of ensuring sufficient stiffness of the support shell 11, forming a plurality of deformation ventilation holes 117 on the support shell 11 is beneficial to the elastic deformation of the support portion 112.

[0061] In this embodiment, deformation ventilation holes 117 are not provided in the installation part 111, but are provided in the support part 112. Since the mounting base 12 needs to provide stronger support for this waist belt, deformation ventilation holes 117 are not provided in the installation part 111 to avoid affecting the structural stability of the installation part 111 due to material reduction in this area, resulting in deformation of the support part 112 under external force, deviation of the internal pulley group 13, and poor sliding of the pull rope 14; setting a plurality of deformation ventilation holes 117 in the support part 112 can give full play to the ventilation function of this waist belt and is beneficial to elastic deformation.

[0062] Optionally, a plurality of reinforcing ribs are provided on the outer surface or the inner surface of the installation part 111.

[0063] In this embodiment, one or both of the outer surface and the inner surface of the installation part 111 are provided with reinforcing ribs, so as to locally strengthen the structural strength of the installation part 111 and ensure that the installation part 111 has sufficient support strength.

[0064] Specifically, the reinforcing rib is one of a convex rib, a convex block, a character, and a pattern provided on the outer side surface of the installation part 111. By being integrally injection-molded with the installation part 111, while enhancing the connection strength, it can be used as a kind of identification of the product, so that additional identification does not need to be set, reducing subsequent processes.

[0065] Optionally, the waist belt further includes a support plate 15. The support plate 15 is of a rigid structure. The support plate 15 is arranged in the installation space and is disposed opposite to the mounting base 12. The pulley group 13 is arranged between the mounting base 12 and the support plate 15.

[0066] In this embodiment, the support plate 15 can also be a rectangular steel plate. The support plate 15 is embedded in the installation space. The support plate 15 further enhances the strength of the entire first adjustment assembly 1 and improves the support effect of the entire first adjustment assembly 1.

[0067] Please refer to the attached Figure 2 、attached Figure 3 、attached Figure 8 and attached Figure 9 . Further, the support plate 15 includes a first plate 151, a second plate 152, and a third plate 153 that are sequentially connected. The first plate 151 and the third plate 153 are respectively disposed opposite to the mounting base 12. The second plate 152 is inclined. A first space and a second space are respectively formed between the first plate 151 and the third plate 153 and the mounting base 12. The heights of the first space and the second space are different. The first space and the second space are used to accommodate pulleys at different heights in the pulley group 13.

[0068] In this embodiment, the support plate 15 is not a flat structure. Specifically, the support plate 15 includes a first plate 151, a second plate 152, and a third plate 153 that are connected in sequence. Of course, the entire support plate 15 can be an integral structure, and the first plate 151, the second plate 152, and the third plate 153 can be formed by a bending process. In this embodiment, the first plate 151 and the third plate 153 are parallel to each other and are both disposed opposite to the mounting seat 12. A first space and a second space are respectively formed between the first plate 151 and the third plate 153 and the mounting seat 12. Since the gaps between the first plate 151 and the third plate 153 and the mounting seat 12 are different, pulleys of different heights can be conveniently arranged in the first space and the second space to meet the selection requirements of the pulley group 13 for pulleys. In fact, when the size of the pulleys of the pulley group 13 is determined, the structure of the support plate 15 can be further designed so that the first space and the second space can accurately adapt to the pulley size. Of course, by the inclined arrangement of the second plate 152, the support plate 15 can also adapt to the curved surface structure inside the support shell 11.

[0069] Please refer to the attached Figure 10 and the attached Figure 11 , optionally, the mounting seat 12 is convexly provided with a positioning shaft 121, and a positioning hole 154 is opened at a position on the support plate 15 relative to the positioning shaft 121. The pulley of the pulley group 13 is sleeved on the positioning shaft 121, and the positioning shaft 121 passes through the positioning hole 154.

[0070] In this embodiment, the mounting seat 12 is convexly provided with a positioning shaft 121 for limiting the pulley. The positioning shaft 121 can be integrally formed on the mounting seat 12 or can be connected to the plate surface of the mounting seat 12 by welding. The positioning shaft 121 is a hollow structure. Under the condition of permitted strength, by making the positioning shaft 121 a hollow structure, the weight of the entire waist belt can be reduced. A pulley is sleeved on the positioning shaft 121, and the other end of the positioning shaft 121 is placed in the positioning hole 154. When the pulling rope 14 is dragged, the limiting effect of the positioning hole 154 on the positioning shaft 121 can ensure the stability of the pulley operation.

[0071] In this embodiment, the mounting seat 12 is convexly provided with a baffle 122. The baffle 122 semi - surrounds the outer periphery of the pulley. The baffle 122 is arranged with a gap from the pulley and is directly opposite to the position where the pulling rope 14 is in contact with the pulley. The baffle 122 can ensure that the pulling rope 14 always winds around the outer periphery of the pulley and does not come off.

[0072] Please refer to the attached Figure 2 , the attached Figure 6 and the attached Figure 7 , optionally, the support shell 11 is provided with a second opening 114 near the first side 115, and the pulling rope 14 passes through the second opening 114 after passing around the pulley group 13.

[0073] In this embodiment, the second opening 114 is a rectangular hole formed in the support shell 11. The pulling rope 14 wound around the pulley set 13 can be led out through the second opening 114, and a control part convenient for the user to hold and pull is arranged at the end of the pulling rope 14 where it leads out of the second opening 114.

[0074] Please refer to the attached Figure 4 and the attached Figure 5 . Optionally, a limiting groove 1141 is arranged on the inner wall of the second opening 114 along the width direction of the second opening 114. A first guiding member 1142 is arranged in the limiting groove 1141. The surface of the first guiding member 1142 is smooth, and the pulling rope 14 can slide on the surface of the first guiding member 1142.

[0075] In this embodiment, the limiting groove 1141 extends along the width direction of the second opening 114. When the user drags the pulling rope 14, the pulling rope 14 rubs against the inner wall of the second opening 114, which is likely to cause structural wear of the support shell 11 and is also likely to break the pulling rope 14 during long-term friction. By embedding the first guiding member 1142 in the limiting groove 1141 and making the outer surface of the first guiding member 1142 contact the pulling rope 14, when the user drags the pulling rope 14, the pulling rope 14 only rubs against the surface of the first guiding member 1142, and the surface of the first guiding member 1142 is smooth, which can reduce the friction coefficient, extend the service life of the pulling rope 14, and also prevent the inner wall of the support shell 11 at the second opening 114 from being worn.

[0076] In this embodiment, the first guiding member 1142 can be made of a metal wire. The outer wall surface of the metal wire is smooth. Two limiting bosses 123 are also arranged on the side wall of the mounting seat 12. The two ends of the metal wire extend towards the inside of the support shell 11, and the two ends of the metal wire are respectively wound around the limiting bosses 123, so as to fix the metal wire.

[0077] Please refer to the attached Figure 1 、the attached Figure 2 、the attached Figure 10 and the attached Figure 11 . Optionally, the pulley set 13 includes a plurality of winding pulleys 131. The axes of the plurality of winding pulleys 131 are collinear. The winding pulley 131 includes two first wire grooves 1311 arranged in parallel. The pulling rope 14 is connected end to end to form a ring structure. The pulling rope 14 passes through the first wire grooves 1311, and the winding pulley 131 is arranged in the first space.
