Embodiment Construction

[0032] see Figure 1-11 As shown, a titanium alloy geometric lock knee joint includes a calf plate 1, an upper knee seat plate 2, and a thigh sleeve 3. The lower end of the calf plate 1 is hinged with a foot plate 4, and the upper end is provided with a knee seat plate 5. The left and right sides of seat plate 5 are respectively provided with left side board 501a and right side board 501b, and one end of described left side board 501a is provided with left support board 502a along the length direction of calf board 1, and one end of right side board 501b is along the length direction of calf board 501b. The length direction of the plate 1 is provided with a right support plate 502b, the above-knee seat plate 2 is hinged on the upper ends of the left support plate 502a and the right support plate 502b, and the thigh sleeve 3 is installed on the lap seat plate 2; Between the plate 501a and the right side plate 501b, a first rotating shaft 6 is rotatably connected at one end away...

Abstract

The invention discloses a novel titanium alloy geometric knee-locking joint. The knee-locking joint comprises a shank plate, a knee upper seat plate and a thigh sleeve, the lower end of the shank plate is hinged to a foot plate, the upper end of the shank plate is provided with a knee lower seat plate, the knee lower seat plate is provided with a left side plate and a right side plate, one end ofthe left side plate is provided with a left support plate, one end of the right side plate is provided with a right support plate, the knee upper seat plate is hinged to the upper ends of the left support plate and the right support plate, and the thigh sleeve is arranged on the knee upper seat plate; a second rotating shaft rotatably connects the left side plate and the right side plate; a left turntable and a right turntable are fixedly arranged on the second rotating shaft; and the shank plate is connected to a pressing sleeve in a sliding manner, two sides of the pressing sleeve are provided with connecting plates, the connecting plates are provided with driving slide grooves, and the left turntable and the right turntable are provided with convex columns. The novel titanium alloy geometric knee-locking joint not only has a simple structure, but also can ensure that the foot plate does not swing when walking, and particularly can effectively prevent the foot plate from rotating around the lower end of the shank plate when standing.

Description

technical field [0001] The invention relates to the technical field of human prosthesis, in particular to a titanium alloy geometric lock knee joint. Background technique [0002] The prosthetic knee joint is an important motor function compensation device for amputees. The installation of prosthetic knee joint can restore the original shape or function of the patient's disabled limb, reduce dysfunction, and enable the patient to live, study and work independently. At present, there are mainly single-axis knee joints, multi-axis knee joints, knee joints with locks, load-bearing self-locking knee joints, hydraulic or pneumatic control knee joints, intelligent prosthetic knee joints and bionic knee joints, etc. to a certain extent. It meets the requirements of prosthetic wearers. However, when the existing titanium alloy geometric lock knee joint is in use, because the foot plate is hinged at the lower end of the calf plate, the foot plate will swing with the lifting of the ...
