However, in actual use, the support structure of traditional lumbar support frames is almost always fixed inside the lumbar support. Due to differences in the body shape of users, the fixed support structure may not be able to be adjusted according to the user's needs, which will result in the lumbar support frame not achieving the best expected effect of distributing pressure. It may even create new pressure points due to the mismatch between the support structure and the curve of the human body, thereby increasing the user's treatment cycle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotary lumbar support frame, which solves the problem that in actual use, the support structure of traditional rotary lumbar support frames is almost always fixed inside the lumbar support. Due to differences in the body shape of users, the fixed support structure may not be able to be adjusted according to the user's needs, resulting in the lumbar support frame's pressure distribution effect not achieving the best expected results.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In actual use, the support structure of traditional lumbar support frames is almost always fixed inside the lumbar support. Due to differences in the body shape of users, the fixed support structure may not be able to be adjusted according to the user's needs, which will result in the lumbar support frame not achieving the best expected effect of distributing pressure. It may even create new pressure points due to the mismatch between the support structure and the curve of the human body, thereby increasing the user's treatment cycle.

[0016] In view of this, the present invention provides a rotary lumbar support frame. This rotary lumbar support frame, through the cooperation of a pressure-distributing seat, a loading groove, a support rod, a first hook surface, and a first rough surface, achieves the effect of dispersing pressure from the outside of the lumbar support frame. It allows users to easily change the position of the support structure according to their needs, and enables the vertical pressure on the waist to be decomposed into components along the diagonal direction of the support structure in a cross-shaped manner, so that the pressure is transmitted to the edge of the lumbar support, avoiding the concentration of pressure on the user's lumbar spine, thereby protecting the user's lumbar spine.

[0017] Example 1, by Figure 1-6 It is known that a type of lumbar support frame includes a lumbar support 1, and a pressure-distributing mechanism is provided on the back of the lumbar support 1. The pressure-distributing mechanism includes a pressure-distributing seat 2, a loading groove 3, a support rod 4, a first hook surface 5, and a first rough surface 6. The pressure-distributing seat 2 is fixedly connected to the back of the lumbar support 1. The outer wall of the pressure-distributing seat 2 is provided with a loading groove 3. The support rod 4 is inserted into the inside of the loading groove 3. The side of the support rod 4 is provided with a first hook surface 5. The outer wall of the first hook surface 5 is fixedly connected to the side of the outer wall of the pressure-distributing seat 2 near the loading groove 3, and the outer wall of the first hook surface 5 is in contact with the back of the lumbar support 1. The side of the outer wall of the first hook surface 5 away from the back of the lumbar support 1 is fixedly connected to the first rough surface 6. The side of the outer wall of the first rough surface 6 away from the first hook surface 5 is fixedly connected to the side of the outer wall of the pressure-distributing seat 2 away from the back of the lumbar support 1. In specific implementation, it is particularly worth noting that the lumbar support 1 is generally shaped like a Chinese character "hui" (a square frame with a hollow center). It can be made of nylon mesh fabric to improve the breathability of the lumbar support 1. A medical silica gel coating can be additionally arranged on the inner layer of the lumbar support 1 to improve the anti-slip performance of the lumbar support 1. The pressure distribution seat 2 is generally formed by a pair of parallel brackets and a pair of cross brackets, and an opening is arranged at the center of the intersection, which is convenient for a user to move the support rods 4. The pressure distribution seat 2 can be made of thermoplastic polyurethane elastomer, so that the pressure distribution seat 2 has a certain deformation capability. A containing groove 3 is formed at each end of the pressure distribution seat 2, a plurality of containing grooves 3 are communicated with each other, and the support rods 4 are accommodated inside the containing grooves 3. There are two support rods 4, the support rods 4 are bendable plastic strips, and the support rods 4 can be made of nickel-titanium alloy. The first hook surface 5 and the first loop surface 6 are nylon hook and loop fasteners, and the area of the first hook surface 5 is slightly larger than that of the first loop surface 6, which is convenient for a user to separate the first hook surface 5 from the first loop surface 6. In an initial state, the two support rods 4 are arranged in parallel inside the pressure distribution seat 2. When the lumbar support 1 cannot meet the expectation of the user, firstly, the user can pinch one end of the first hook surface 5 and exert force towards a side away from the first loop surface 6, so as to drive the first hook surface 5 to separate from the first loop surface 6. At this time, the support rods 4 located inside the containing grooves 3 are exposed, and the user draws the support rods 4 out, the same operation is performed on the other support rod 4, so that both the two support rods 4 are separated from the containing grooves 3. Then, the user resets the first hook surface 5 and the first loop surface 6 at the horizontal position, and then separates the two crossed first hook surfaces located on the same side from the two corresponding first loop surfaces 6 through the above method. At this time, the two containing grooves 3 located on the same side of the cross structure are opened (that is, the two first hook surfaces located above and below the two parallel first hook surfaces are opened). Finally, the user inserts the two support rods 4 into the two containing grooves 3 respectively, and the two support rods 4 meet at the center of the pressure distribution seat 2. Since the pressure distribution seat 2 has certain elasticity, the position of one support rod 4 is determined first, and the other support rod 4 moves from the outside of the first support rod to the final position through the opening in the outer wall of the pressure distribution seat 2. The two support rods 4 finally form an "X" shape, and then the two first hook surfaces 5 are reset, that is, the adjustment is completed. The X-shaped structure forms "diagonal support" through two crossed support rods 4. When the waist bears vertical pressure (such as self-weight load during sitting for a long time and standing), the X-shaped rods can decompose the pressure into component forces along the diagonal direction, conduct the component forces to the edge of the lumbar support 1 towards both sides through the intersection point, and finally conduct the component forces to the back and the hips, so as to avoid pressure concentration on the middle part of the lumbar vertebra, thereby achieving the purpose of distributing pressure, further improving the pressure distribution effect on the basis of the hui-shaped lumbar support frame, and further improving the wearing comfort of the user; Further, a second hook surface 7 is fixedly connected to the front side of the lumbar support 1, and a second loop surface 8 is fixedly connected to the side of the back surface of the lumbar support 1 away from the pressure distribution seat 2; In the specific implementation process, it is worth noting that the second hook surface 7 and the second rough surface 8 are nylon Velcro. The area of ​​the second hook surface 7 is smaller than that of the second rough surface 8. When using it, the user holds the second hook surface 7 and the second rough surface 8 with both hands respectively, and folds it around the waist. According to the user's feeling, the second hook surface 7 can be fixed to the second rough surface 8 in a suitable position, which improves the wearing convenience of the loop-type waist support frame. Furthermore, a fixing mechanism is provided between the second hook surface 7 and the second rough surface 8; the fixing mechanism includes a first groove 9, a lifting button 10, a buckle 11, and a second groove 12; the first groove 9 is opened on the outer wall of the second hook surface 7 away from the front of the waist support 1, the lifting button 10 is fixedly connected inside the first groove 9, the buckle 11 is snapped onto the outer wall of the lifting button 10, the second groove 12 is sleeved on the outer wall of the buckle 11, and the second groove 12 is opened on the outer wall of the second rough surface 8 away from the back of the waist support 1. In the specific implementation process, it is worth noting that there are five first grooves 9 arranged vertically, and each groove is fixedly connected to a hinge 10. The hinge 10 can be made of polyoxymethylene. There are multiple sets of buckles 11, with five in each set, corresponding one to one with the hinge 10. The buckle 11 is made of the same material as the hinge 10. Under normal circumstances, the user fixes the waist support 1 through the second hook surface 7 and the second rough surface 8. At this time, the hinge 10 and the buckle 11 can enhance the stability of the waist support 1 when worn and prevent slippage or displacement. When the second hook surface 7 or the second rough surface 8 fails, the user can fix it through the hinge 10 and the buckle 11, which can also achieve the same fixing effect, ensure the functionality of the waist support 1, and improve the service life of the waist support 1. Example 2, by Figure 1-6 It can be seen that the side of the waist support 1 away from the second hook surface 7 is fixedly connected to the support frame 13; In the specific implementation process, it is worth noting that the front of the support frame 13 is designed to protect the waist 1, and a sponge pad is provided on its outside. The material of the support frame 13 can be a blend of elastic polyester fiber and spandex, which can combine rigidity and elasticity. It acts around the waist of the human body to distribute the pressure on the waist, thereby improving the stability and comfort of the waist support. Furthermore, pressure-reducing pads 14 are provided on both sides of the support frame 13, and the outer wall of the pressure-reducing pads 14 is fixedly connected to the front of the waist support 1. In the specific implementation process, it is worth noting that there are two pressure-distributing pads 14, located on both sides of the support frame 13. They are buffer layers that come into contact with the human body. Their material can be memory foam, which can ensure comfort and distribute local pressure. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
