Description

Technical Field

[0001] The utility model relates to the technical field of leg support frames, and more specifically, to a leg support frame for nursing. Background Art

[0002] In the prior art, a nursing leg support is an important medical auxiliary device used to support and fix the patient's legs to help recover or relieve pain. However, the existing leg support has certain limitations in design, especially in the adjustment of the support strength. This defect has a significant impact on the convenience and effect of use.

[0003] First, the inability to adjust the support strength means that the leg brace cannot be personalized to the specific needs of different patients. Different patients have different body shapes, injury sites, and recovery stages, and a fixed support strength may not provide them with the best support and comfort. For example, some patients may need a stronger support to immobilize the injury, while others may need a lighter support to promote blood circulation.

[0004] Secondly, a non-adjustable brace may cause discomfort to the patient during long-term use. As the recovery process progresses, the patient's support needs may change, but a fixed-force brace cannot adapt to these changes. This may not only delay the recovery process, but also increase the patient's pain and discomfort. Utility Model Content

Multiple fixing grooves 10 are respectively equidistantly opened on the multiple adjusting disks 9, and an intermediate column 11 is respectively clamped in each fixing groove 10. Screws 12 are respectively provided at both ends of the intermediate column 11, and nuts 13 are threaded on the screws 12. The nuts 13 fit on the adjusting disks 9. Each screw 12 is respectively provided with a hexagonal section 14, and the hexagonal section 14 and the intermediate column 11 are coaxially arranged. The supporting mechanism includes a folding plate 19, a cylinder 20 and a leg support 21. The folding plate 19 is installed on the intermediate wheel 3, and the leg support 21 is rotatably connected to the fixed rod 1. The cylinder 20 is respectively rotatably connected to the folding plate 19 and the leg support 21. An intermediate plate 22 is rotatably provided on the leg support 21, and the intermediate plate 22 is rotatably connected to the folding plate 19.

[0032] In this embodiment, when it is necessary to adjust the supporting strength of the leg rest 21, first, according to the situation of the required adjustment strength, the middle column 11 of different lengths is selected and stuck in multiple fixing grooves 10, and then the nut 13 is threadedly connected to the screw 12. The connection between the nut 13 and the screw 12 can be facilitated by the hexagonal section 14. The spring 8 is connected to the adjustment disk 9 of the connected part. The spring 8 of this part cannot participate in the transmission of elastic force, so the length of the spring 8 will be changed. After the length of the spring 8 changes, the stiffness coefficient will change accordingly. Therefore, when the spring 8 is compressed to the same length, the elastic force generated is greater, so a greater thrust will be applied to the two clamping disks 2, so the force of the rotation of the folding plate 19 can be changed, thereby completing the adjustment process. Under the synchronous action of the cylinder 20, a supporting force can be applied to the leg rest 21. When the leg is attached to the leg rest 21, a thrust is applied synchronously by the cylinder 20 and the spring 8, thereby ensuring the generation of supporting force, and the supporting force is transmitted through the folding plate 19 and the middle plate 22.

[0033] See also Figure 1 As an implementation method of a nursing leg support frame for the connecting mechanism: the connecting mechanism includes an adjusting rod 15 and a threaded sleeve 16, the adjusting rod 15 is coaxially installed on the pull rod 5, the threaded sleeve 16 is threadedly connected to the adjusting rod 15, an adjusting sleeve 17 is provided on the threaded sleeve 16, a resistance sleeve 18 is provided on the spring 8, the resistance sleeve 18 is slidably connected to the pull rod 5, and the adjusting sleeve 17 is pressed against the resistance sleeve 18.

[0034] More specifically, when the resistance sleeve 18 on the spring 8 needs to be fixed, the threaded sleeve 16 is first threadedly connected to the adjusting rod 15, so that the resistance sleeve 18 is pressed against the adjusting sleeve 17. When the spring 8 applies thrust, the threaded sleeve 16 limits the position of the resistance sleeve 18, thereby ensuring the generation of thrust.

[0035] In summary, when the overall equipment is in use or running: when it is necessary to adjust the supporting strength of the leg rest 21, first select the intermediate columns 11 of different lengths according to the strength to be adjusted and clamp them in multiple fixing grooves 10, and then thread the nut 13 on the screw 12. The connection between the nut 13 and the screw 12 can be facilitated by the hexagonal section 14. The spring 8 is connected to the adjustment disk 9 of the connected part. The spring 8 of this part cannot participate in the transmission of elastic force, so the length of the spring 8 will be changed. After the length of the spring 8 changes, the stiffness coefficient will change accordingly. Therefore, when the spring 8 is compressed to the same length, the elastic force generated is greater, so a greater thrust will be applied to the two clamping disks 2, so the force of the rotation of the folding plate 19 can be changed, thereby completing the adjustment process. Under the synchronous action of the cylinder 20, a supporting force can be applied to the leg rest 21. When the leg is attached to the leg rest 21, a thrust is applied synchronously by the cylinder 20 and the spring 8, thereby ensuring the generation of the supporting force, and the supporting force is transmitted through the folding plate 19 and the intermediate plate 22.

[0036] When the abutment sleeve 18 on the spring 8 needs to be fixed, the threaded sleeve 16 is first threadedly connected to the adjusting rod 15, so that the abutment sleeve 18 is pressed against the adjusting sleeve 17. When the spring 8 applies thrust, the threaded sleeve 16 limits the position of the abutment sleeve 18, thereby ensuring the generation of thrust.

[0037] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
