[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0031] Combine the following Figures 1 to 3 The utility model is described as a universally adjustable crutch.

[0032] like Figures 1 to 3 As shown, the utility model provides a universal adjustable crutch, comprising an adjusting sleeve 1, a support rod 2, a support base 3, an adjusting member 4 and a connecting member 5.

[0033] Among them, the support rod 2 is inserted into the adjusting sleeve 1 from top to bottom, the supporting base 3 is rotatably connected to the lower end of the adjusting sleeve 1, the adjusting member 4 is threadedly connected to the adjusting sleeve 1, the adjusting member 4 is located on the upper side of the supporting base 3, and the adjusting member 4 is used to limit the rotation angle of the supporting base 3. The connecting member 5 passes through the adjusting sleeve 1 and the supporting base 3 from top to bottom, and the connecting member 5 is used to limit the supporting base 3 from being separated from the adjusting sleeve 1.

[0034] In the universal adjustable crutch provided in the present embodiment, like the commonly used universal adjustable crutch, the adjusting sleeve 1 is arranged on the supporting base 3, and the adjusting sleeve 1 can drive the supporting rod 2 to adjust the direction on the supporting base 3. Relative to the supporting rod 2, the supporting base 3 can rotate along the horizontal axis or along the vertical axis, thereby realizing universal rotation, and the adjusting member 4 is threadedly connected to the adjusting sleeve 1, and the adjusting member 4 can adjust its position on the adjusting sleeve 1, that is, the distance between the adjusting member 4 and the supporting base 3, by rotating itself, so as to limit the rotation angle of the supporting base 3 along the horizontal axis. For example, when the distance between the adjusting member 4 and the supporting base 3 is one centimeter, the rotation angle of the supporting base 3 is 10°, and when the distance between the adjusting member 4 and the supporting base 3 is two centimeters, the rotation angle of the supporting base 3 is 20°, that is, the relative angle between the supporting rod 2 and the supporting base 3 can be limited during use to avoid the situation where the user falls due to excessive rotation angle, which is safer.

[0035] In some embodiments, an adjustment boss 6 is provided on the top of the support base 3, and the cross-section of the adjustment boss 6 is trapezoidal. A receiving groove adapted to the shape of the adjustment boss 6 is provided on the bottom of the adjustment member 4, and the cross-section of the receiving groove is trapezoidal. The adjustment member 4 is covered on the adjustment boss 6, and the top of the support base 3 is set as a boss structure. The cross-sections of the adjustment boss 6 and the receiving groove are both trapezoidal. The adjustment member 4 can better fit the adjustment boss 6 and the support base 3, and can better limit the rotation angle of the support base 3.

[0036] In some embodiments, the lower end of the adjusting sleeve 1 is hemispherical, and a rotation groove is provided in the middle of the adjusting boss 6. The rotation groove is hemispherical and matched with the adjusting sleeve 1. The lower end of the adjusting sleeve 1 is set to be hemispherical, which can make the rotation of the supporting base 3 smoother.

[0037] In some embodiments, the universal adjustable crutch also includes an adjusting nut 7 and a buffer spring 8, the adjusting nut 7 is threadedly connected to the lower end of the connecting member 5, the lower end of the buffer spring 8 abuts against the adjusting nut 7, and the upper end of the buffer spring 8 abuts against the supporting base 3.

[0038] Specifically, the adjusting nut 7 is sleeved on the lower end of the connecting member 5, and a buffer spring 8 is connected between the adjusting nut 7 and the supporting base 3. When the connecting member 5 tilts along with the adjusting sleeve 1, if the adjusting nut 7 at the other end is not restricted by the buffer spring 8, the adjusting nut 7 can tilt along with the connecting member 5 unimpeded. However, after the buffer spring 8 is arranged between the adjusting nut 7 and the supporting base 3, the buffer spring 8 will be twisted in the process of tilting along with the adjusting nut 7, generating a certain twisting force, thereby slowing down the tilting speed of the adjusting nut 7 and the connecting member 5, making the rotation softer, and enabling the user to better control the crutch.

[0039] In some embodiments, the buffer spring 8 is a conical spring, which can provide greater lateral stability and less bending tendency, and can effectively slow down the tilting speed of the connecting member 5 and the adjusting sleeve 1.

[0040] In some embodiments, the universal adjustable crutch also includes a protective cover 9, which is detachably connected to the support base 3. A receiving cavity is provided inside the protective cover 9, and the adjusting nut 7 and the buffer spring 8 are both located in the receiving cavity. By providing the protective cover 9, the adjusting nut 7 and the buffer spring 8 can be protected from corrosion and their service life can be extended.

[0041] Furthermore, the protective cover 9 is threadedly connected to the supporting base 3, which is very convenient for both disassembly and installation.

[0042] In some embodiments, the adjusting sleeve 1 and the supporting base 3 are both provided with a connecting through hole 10 for the connecting member 5 to pass through. The outer diameter of the connecting member 5 is smaller than the inner diameter of the connecting through hole 10. The connecting through hole 10 serves to limit the tilting angle of the connecting member 5. Specifically, the adjusting sleeve 1 will drive the connecting member 5 to tilt during the tilting process. Since the connecting through hole 10 is provided on the supporting base 3 and the connecting member 5 passes through the connecting through hole 10, the tilting rotation of the connecting member 5 is restricted by the connecting through hole 10, and the tilting angle of the connecting member 5 is affected. Furthermore, the aperture of the connecting through hole 10 is between 10 mm and 16 mm, and the tilting angle of the connecting member 5 restricted by the connecting through hole 10 is between 20° and 25°.

[0043] In some embodiments, the universal adjustable crutch also includes a limit pin 11 and a limit spring 12. The outer walls of the adjustment sleeve 1 and the support rod 2 are provided with a limit hole 13 adapted to the limit pin 11. The limit spring 12 is arranged at the upper end of the connecting member 5. The limit spring 12 is connected to the limit pin 11 to drive the limit pin 11 to be inserted into the limit hole 13. The limit spring 12 is used to drive the limit pin 11 to be inserted into the limit hole 13, which is very convenient for disassembly and installation.

[0044] In some embodiments, the universal adjustable crutch also includes multiple support feet 14, which are detachably connected to the bottom of the support base 3. The support feet 14 play a supporting role to prevent the support base 3 from directly contacting the ground, thereby increasing the service life of the support base 3. Furthermore, rubber foot pads can be provided at the bottom of the support feet 14, which can reduce the wear of the support feet 14 and increase the service life of the support feet 14.

[0045] In some embodiments, the universal adjustable crutch further includes a crutch head 15 , which is disposed at the upper end of the support rod 2 , making it more convenient to use.

[0046] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
