Described knee joint includes bearing 4, side cover 5, nut 6, rotatable axle bed 7, sprocket shaft 8, joint housing 14, chain 15, sprocket wheel the 16, first limbs and the second limbs；Described first limbs include first stop the 17, first spring the 18, first pull bar 19, the first spacing adjusting nut 20 and the first movable spring seat 21, described second limbs include that the second stop 23, second is spacing Adjusting nut the 24, second spring the 25, second pull bar 26 and the second movable spring seat 27.Described rotatable axle bed 7 and described negative pressure Bucket 1 connects, and described joint housing 14 is positioned at below negative pressure bucket 1, and described joint housing 14 is used for accommodating described chain 15, described Sprocket wheel 16 and described sprocket shaft 8；Described rotatable axle bed 7 is located at the two ends of sprocket shaft 8 and is positioned at the both sides of joint housing 14, Bearing 4 is located on rotatable axle bed 7, and nut 6 is contained in the two ends of sprocket shaft 8 and is fixed on by sprocket shaft 8 on rotatable axle bed 7, Sprocket wheel 16 is located on sprocket shaft 8, and chain 15 is located on sprocket wheel 16, and described side cover 5 is located at the outside of rotatable axle bed 7 so that by spiral shell Female 6 cover；One end of described chain 15 is connected with the upper end of the first pull bar 19, the other end of described chain 15 and the second pull bar 26 Upper end connect；Described first stop 17 is located at the top in the first limbs, and the center of described first stop 17 is porose, institute Stating the lower end of the first pull bar 19 to be connected through the hole at the first stop 17 center with the first movable spring seat 21, the first spring 18 fills On the first pull bar 19 and between the first stop 17 and the first movable spring seat 21, the first spacing adjusting nut 20 is located at The bottom of the first pull bar 19；Described second stop 23 is located at the top in the second limbs, the center of described second stop 23 Porose, the lower end of described second pull bar 26 is connected through the hole at the second stop 23 center with the second movable spring seat 27, and second Spring 25 is contained on the second pull bar 26 and between the second stop 23 and the second movable spring seat 27, the second spacing adjustment spiral shell Female 24 are located on the second pull bar 26；First limbs and the second limbs are located at below joint housing 14 and the first limbs are positioned at second Before limbs；Described first stop 17 and described second stop 23 are respectively used to limit described first spring 18 and described The upper end position of the second spring 25.

Described ankle joint includes adjustable spring seat 9, inclination angle balance back-moving spring 10, universal joint 11, fixing spring base 12 and The gudgeon of universal joint 13；The upper end of described universal joint 11 is connected with the lower end of the second limbs by the gudgeon of universal joint 13, universal joint 11 times End is connected by the upper end of the gudgeon of universal joint 13 with artificial limb foot, and described adjustable spring seat 9 is located at the bottom of the second limbs, described solid Determining spring base 12 and be located at the upper end of artificial limb foot, described inclination angle balance back-moving spring 10 is located at above artificial limb foot, is wound in institute State on universal joint 11, and between adjustable spring seat 9 and fixing spring base 12.

When this utility model uses, when human body is squatted down, the negative pressure bucket 1 accommodating deformed limb drive rotatable axle bed 7 (negative pressure Bucket 1 and rotatable axle bed 7 are connected), then driven described sprocket shaft 8 and sprocket wheel 16 by rotatable axle bed 7, by sprocket wheel 16 Described chain 15 is driven to interlock so that the most described first spring 18 of described first movable spring seat 21, described second bullet Spring 25 and described second movable spring seat 27 expand downwards stretching, it is to avoid chain 15 folds or takes off tooth.When human body is by the state of squatting down When being transformed to standing state, chain 15 is pulled by the higher expansionary force being extruded generation by the first movable spring 18, by Chain 15 band movable sprocket 16 and sprocket shaft 8 move, then are driven rotatable axle bed 7 and negative pressure bucket 1 to assist human body station by sprocket shaft 8 Vertical.

When standing, the first spring 18 is in expansion state, and the second spring 25 is in the compressive state of respective degrees, and by Two spacing adjusting nuts 24 limit the compression degree of the second spring 25.When squatting down, the first spring 18 is in compressive state, and by One spacing adjusting nut 20 limits the compression degree of the first spring 18 and degree of squatting down, and the second spring 25 is in expands shape accordingly State, it is to avoid chain 15 folds or takes off tooth.

Wherein, due to different people when walking, leg all has certain flexibility, and therefore, this utility model passes through Second spacing adjusting nut 24 is set so that user can adjust the second spacing adjusting nut 24 according to self walking habits and exist Position on second pull bar 26, so that the angle of walking is mated with user's walking habits.When adjusting the according to personal habits Behind the two spacing adjusting nuts 24 position on the second pull bar 26, when can reach walking, calf respective angles returns naturally Bend.It addition, by arranging the second spacing adjusting nut 24, when can reach to stand, the second spring 25 will not the effect of reverse inflection Really.

Further, by arranging the second spring 25, so that chain 15 is unlikely to folding occur in the course of the work Or the phenomenon disconnected.

Further, since different user is when squatting down, the angle squatted down also is not quite similar, and therefore, is using this multi-functional vacation During limb, user can regulate the first spacing adjusting nut 20 position on the first pull bar 19 according to own situation, so that Angle of squatting down meets the custom of squatting down of self.

This utility model takes into full account that in naked joint artificial limb, when landing, has convex-concave can go out in the case of tilting on ground The problem of existing stationarity difference, combines by universal joint and inclination angle are balanced back-moving spring, makes the stationarity problem of landing of artificial limb It is resolved.
