[0008] The adjusting mechanism comprises a tightness component, a pawl component, a one-way transmission component and a driving component which are respectively rotatably arranged on the sock body; the tightness component is connected with the tight elastic rope, the pawl component can prevent the tightness component from reversing; the rotation of the tightness component can drive the one-way transmission component to rotate, and vice versa; the rotation of the one-way transmission component can unidirectionally drive the driving component to rotate, and vice versa; the transmission belt tightly encloses the driving components of two adjacent adjusting mechanisms, and the rotation of one driving component can cause the rotation of another driving component through the transmission belt.

[0009] Further, the tightness assembly comprises a ratchet shaft, a ratchet gear and a ratchet body; the ratchet shaft is rotatably connected to the sock body, two ends of the tight elastic rope are respectively arranged on the ratchet shaft, and the ratchet gear and the ratchet body are coaxially and fixedly connected to the sock body; the ratchet gear can drive the one-way transmission assembly to rotate, and vice versa; the pawl assembly can prevent the ratchet body from reversing.

[0010] Further, the pawl assembly comprises a pawl shaft, a torsion spring and a first pawl; the pawl shaft is arranged on the sock body, the first pawl is rotatably connected to the pawl shaft and connected to the pawl shaft through the torsion spring, and the first pawl can prevent the ratchet body from reversing.

[0011] Further, the one-way transmission assembly comprises a transmission shaft, a transmission gear, a one-way rotating disc, a second pawl and a one-way spring; the transmission shaft is rotatably connected to the sock body, the transmission gear and the one-way rotating disc are coaxially and fixedly arranged on the transmission shaft; the transmission gear and the ratchet gear are engaged, the second pawl is slidably connected to the one-way rotating disc along the radial direction of the one-way rotating disc and connected to the transmission shaft through the one-way spring; the rotation of the one-way rotating disc can drive the driving assembly to rotate in one direction through the second pawl, and vice versa.

[0012] Further, the driving assembly comprises a fixed rod and an inner ratchet ring; the fixed rod is fixedly arranged on the sock body, the inner ratchet ring is rotatably connected to the fixed rod and coaxial with the transmission shaft, and the transmission belt tightly surrounds the inner ratchet rings of two adjacent driving assemblies; the inner ratchet ring can drive the second pawl to rotate in one direction, and vice versa.

[0033] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, therefore only as an example, and cannot limit the protection scope of the present application.

[0034] Please refer to Figures 1-6 , the embodiment provides an adjustable varicose socks, including sock body 1, tight elastic rope 2, adjustment mechanism 3 and transmission belt 4. It should be understood that the sock body 1 itself has a certain elasticity, after wearing can give a certain pressure.

[0035] The tight elastic rope 2 is provided with a plurality of tight elastic rope 2 close to the circumference of the sock body 1, and is connected with the adjustment mechanism 3, the adjustment mechanism 3 and the tight elastic rope 2 one by one, two adjacent adjustment mechanism 3 is connected through the transmission belt 4. In the embodiment, the tight elastic rope 2 and the adjustment mechanism 3 are respectively provided with two groups, more can be set according to the demand in actual production.

[0036] The adjusting mechanism 3 comprises a tightness assembly 31, a pawl assembly 32, a one-way transmission assembly 33 and a driving assembly 34 rotatably arranged on the sock body 1 respectively; the tightness assembly 31 is connected with the tight elastic rope 2, the pawl assembly 32 can prevent the tightness assembly 31 from reversing; the rotation of the tightness assembly 31 can drive the rotation of the one-way transmission assembly 33, and vice versa; the rotation of the one-way transmission assembly 33 can unidirectionally drive the rotation of the driving assembly 34, and vice versa; the driving assemblies 34 of two adjacent adjusting mechanisms 3 are tightly surrounded by the transmission belt 4, and the rotation of one driving assembly 34 can cause the rotation of the other driving assembly 34 through the transmission belt 4. It should be understood that the rotation of the tightness assembly 31 can drive the rotation of the one-way transmission assembly 33, and the rotation of the one-way transmission assembly 33 can drive the rotation of the tightness assembly 31; the rotation of the one-way transmission assembly 33 can unidirectionally drive the rotation of the driving assembly 34, and the rotation of the driving assembly 34 can unidirectionally drive the rotation of the one-way transmission assembly 33. In this embodiment, the clockwise rotation of the driving assembly 34 drives the clockwise rotation of the one-way transmission assembly 33, and further drives the counterclockwise rotation of the tightness assembly 31; the clockwise rotation of the driving assembly 34 can drive the clockwise rotation of the one-way transmission assembly 33, but the counterclockwise rotation of the driving assembly 34 cannot cause the rotation of the one-way transmission assembly 33; the clockwise rotation of the one-way transmission assembly 33 cannot cause the rotation of the driving assembly 34, and the counterclockwise rotation of the one-way transmission assembly 33 can cause the rotation of the driving assembly 34. Through the above arrangement, the reverse rotation of the tightness assembly 31 can independently reduce the pressure in the area where it is located, and the reverse rotation of the driving assembly 34 caused by accidental touch is avoided, thereby reducing the overall pressure.

[0037] In other schemes, the tightness assembly 31 comprises a ratchet shaft 311, a ratchet gear 312 and a ratchet body 313; the ratchet shaft 311 is rotatably connected to the sock body 1, and the two ends of the tight elastic rope 2 are arranged on the ratchet shaft 311 respectively; the ratchet gear 312 and the ratchet body 313 are coaxially and fixedly connected to the sock body 1 respectively; the ratchet gear 312 can drive the rotation of the one-way transmission assembly 33, and vice versa, and the pawl assembly 32 can prevent the reverse rotation of the ratchet body 313.

[0038] In other schemes, the pawl assembly 32 comprises a pawl shaft 321, a torsion spring 322 and a first pawl 323; the pawl shaft 321 is arranged on the sock body 1, and the first pawl 323 is rotatably connected to the pawl shaft 321 and connected to the pawl shaft 321 through the torsion spring 322; the first pawl 323 can prevent the reverse rotation of the ratchet body 313.

[0039] In other embodiments, the one-way transmission assembly 33 includes a transmission shaft 331, a transmission gear 332, a one-way turntable 333, a second pawl 334, and a one-way spring 334. The transmission shaft 331 is rotatably connected to the sock body 1, and the transmission gear 332 and the one-way turntable 333 are coaxially fixed on the transmission shaft 331. The transmission gear 332 meshes with the ratchet gear 312, and the second pawl 334 is radially slidably connected to the one-way turntable 333 and connected to the transmission shaft 331 through the one-way spring 334. The rotation of the one-way turntable 333 can drive the drive assembly 34 to rotate unidirectionally through the second pawl 334, and vice versa.

[0040] In other embodiments, the drive assembly 34 includes a fixed rod 341 and an inner ratchet ring 342. The fixed rod 341 is fixed to the stocking body 1, and the inner ratchet ring 342 is rotatably connected to the fixed rod 341 and coaxial with the transmission shaft 331. The transmission belt 4 tightly wraps around the inner ratchet rings 342 of two adjacent drive assemblies 34. The inner ratchet ring 342 can drive the second pawl 334 to rotate in one direction, and vice versa. It should be understood that the inner ratchet ring 342 has ratchet teeth corresponding to the second pawl 334, so that there is unidirectional transmission between it and the second pawl 334.

[0041] In other designs, the sock body 1 has an opening on one side, with Velcro straps on both sides of the opening. These Velcro straps allow the sock body 1 to be connected into a loop. The opening makes it easier for the wearer to put on the sock, while the Velcro straps allow for easier fastening and sealing, and also facilitate initial pressure adjustments.

[0042] Furthermore, the stocking body 1 also has a pocket inside, which can be filled with a medicine packet. By setting up the pocket and filling it with a medicine packet, the effect of the medicine can be enhanced on specific areas, meeting more needs.

[0043] The process of using the adjustable varicose vein stockings described above is as follows: By rotating any one of the drive components 34, all the other drive components 34 will rotate together. The rotating drive component 34 drives the one-way transmission component 33 to rotate in one direction, and the rotation of the one-way transmission component 33 will drive the rotation of the tensioning component 31. Since the tensioning component 31 is connected to the elastic cord 2, the rotation of the tensioning component 31 will cause the elastic cord 2 to wrap around the tensioning component 31. The pawl component 32 can prevent the tensioning component 31 from reversing, that is, prevent the elastic cord 2 from loosening, and the area will be tightened and pressurized. Since all the drive components 34 rotate at the same time, the elastic cords 2 of each part will gradually wrap around their corresponding tensioning components 31, and all areas will be pressurized, thereby completing the overall pressure adjustment.

[0044] When it is needed to reduce the local pressure, the pawl assembly 32 of the area needed to be reduced is rotated, the tightness assembly 31 is gradually reversed, the elastic cord 2 is gradually loosened, although the reverse of the tightness assembly 31 will cause the reverse of the one-way transmission assembly 33, but due to the one-way transmission characteristics of the one-way transmission assembly 33 and the driving assembly 34, the reverse of the one-way transmission assembly 33 will not cause the reverse of the driving assembly 34, that is, loosening the elastic cord 2 of the area will not cause the rotation of the remaining driving assembly 34, thus the pressure of the specific area can be reduced.

[0045] The adjustable varicose socks can adjust the compression force as a whole and reduce the pressure of specific areas according to the needs.

[0046] The above examples are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
