Description

Technical Field

[0001] This utility model relates to the field of knee joint pad technology, and in particular to an adjustable knee joint pad. Background Technology

[0002] In the fields of rehabilitation medicine, sports injury recovery, and daily care, knee joint fixation and angle adjustment are common needs. During surgery, the angle needs to be adjusted to facilitate joint treatment and medication. During medication and treatment, the joint flexion direction must be kept fixed. After surgery, the knee joint flexion angle needs to be gradually adjusted to restore function. Existing knee joint fixation devices often have problems such as inaccurate angle adjustment, inability to adapt to users with different leg lengths, and poor comfort. Utility Model Content

[0003] Therefore, to address the aforementioned problems, this utility model proposes an adjustable knee joint pad. It solves the technical problem that existing knee joint pads are not easily adjustable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable knee pad includes a thigh pad, a calf pad rotatably disposed on one side of the thigh pad, and a rotating assembly disposed between the thigh pad and the calf pad. The thigh pad and the calf pad have receiving grooves, and an extension plate is slidably disposed within the receiving grooves. The extension plate extends beyond the receiving grooves. The thigh pad and the calf pad have fixing members for securing the extension plate. The rotating assembly includes a fixing block disposed on the thigh pad and the calf pad, a rotating block rotatably disposed on the fixing block, two screws disposed on the two rotating blocks, and a rotating rod connecting the ends of the two screws. The threads on the two screws are opposite, and the rotating rod has an internal thread. One end of each of the two screws is located inside the rotating rod and threadedly connected to it.

[0006] Further:

[0007] The fastener includes multiple insertion holes on the extension plate, through grooves on the thigh pad and calf pad, a push rod passing through the through groove, and a first spring in the through groove. One end of the push rod extends out of the through groove, and the other end of the first spring is provided with an insertion block. The first spring is sleeved on the push rod, and the first spring can push the insertion block to be inserted into the insertion hole.

[0008] The thigh pad and calf pad are detachably placed on a base plate, which has multiple slots, and the end of the extension plate can be locked into the corresponding slot.

[0009] The receiving groove is provided with sliding grooves on both sides, and the extension plate is provided with sliders on both sides, and the sliders can slide along the sliding grooves.

[0010] The calf pad is provided with an arc-shaped frame, and multiple second springs are provided inside the arc-shaped frame. The other end of each second spring is provided with an arc-shaped plate.

[0011] The extension plate at the calf pad is provided with a foot support plate, and the top of the foot support plate is covered with a sponge pad.

[0012] The calf pad is provided with at least one long groove, and an elastic diaphragm is provided on the long groove, and the elastic diaphragm is provided with multiple air vents.

[0013] The thigh pad is provided with fixing straps on both sides. One side of the fixing strap has a hook and loop fastener side, and the other side of the fixing strap has a loop fastener side.

[0014] The thigh pad and calf pad are equipped with flexible pads.

[0015] The surface of the rotating rod is provided with anti-slip texture.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] In use, rotating the rotating rod precisely adjusts the angle between the thigh pad and the calf pad to meet different usage needs. The extension length of the extension plate can also be adjusted according to the height of different patients, adapting to various usage scenarios and users with different leg lengths. Furthermore, through the cooperation of the push rod and the first spring, the extension plate can be firmly fixed in the desired position, preventing slippage during use. Furthermore, the bottom of the extension plate is secured in the corresponding slot, providing good fixation and preventing accidental unfolding or retraction of the thigh and calf pads. Furthermore, the arc-shaped frame and arc-shaped plate design provide better support for the calf, while the second spring increases comfort and reduces localized pressure. Furthermore, the foot support plate provides support for the foot, helping to maintain knee joint stability. Furthermore, the long groove and elastic diaphragm increase the breathability of the calf pad, reducing stuffiness during prolonged use; the elastic diaphragm adapts to the shape changes of the calf, maintaining a close fit. Furthermore, the design of the fixing straps and Velcro ensures a secure fixation between the thigh pad and the thigh, preventing displacement of the device during use. Attached Figure Description
