Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the scope of the present invention is not limited by the disclosure below.
The technical solution of the present invention will be further explained with reference to fig. 1, fig. 2, fig. 3 and fig. 4.
A first embodiment, as shown in fig. 1, 2, 3 and 4: a mechanical stop mechanism for an ankle joint, comprising: switching dish 1 and rotatable setting are in connecting plate 2 of 1 one end of switching dish, connecting plate 2 on be provided with locating part 3, locating part 3 include spacing knob fixing base 4 and spacing knob 5, spacing knob 5 including the little double-screw bolt that sets gradually, big double-screw bolt and nut, fixing base 4 in set gradually with 5 little screw hole and the big screw hole that match of spacing knob, the big screw hole in be provided with compression spring 6, spacing knob 5 can rotate out the setting and be in spacing knob fixing base 4 on, switching dish 1 in be provided with the confession 5 gliding arc spacing groove 7 of portion of screwing out of spacing knob.
The limiting pieces 3 are sequentially arranged on the connecting plate 2 in two groups. The arc-shaped limiting grooves 7 are sequentially arranged in the adapter plate 1 in two groups. The other end of the adapter plate 1 is provided with a motor 8, and the output end of the motor 8 penetrates through the adapter plate 1 to be connected with the connecting plate 2;
the outer side of the connecting plate 2 is provided with a shank supporting component 9, the shank supporting component 9 comprises a shank supporting connecting plate 10, a shank support 11 and a directional limit knob 12, the shank supporting connecting plate 10 is provided with a reversing shaft fixing plate 13, the shank support 11 is provided with a reversing shaft 14, the reversing shaft 14 is detachably arranged on the reversing shaft fixing plate 13 through the directional limit knob 12, the reversing shaft fixing plate 13 and the reversing shaft 14 are rotatably arranged, and the shank supporting connecting plate 10 is rotatably arranged on the outer side of the connecting plate 2. The leg support 11 is provided with a leg support binding belt 15.
In the using process: when the limit knob 5 is screwed into the limit knob fixing seat 4, the small screw column can be screwed out of the connecting plate 2 and is matched with the arc-shaped limit groove 7 to form a limit area. When the limit knob 5 is screwed out of the limit knob fixing seat 4, the large stud can be ejected out of the limit knob fixing seat 4 by means of the compression spring 6, and at the moment, the small stud is ejected out of the arc-shaped limit groove 7, so that the limit state is released.
When the limit knob 5 is screwed in, the limit knob 5 can be screwed in the limit knob fixing seat 4 through the compression spring 6; when the limit knob 5 is screwed out, the compression spring 6 can push the large stud out of the large threaded hole to stop rotating, so that the small stud is ensured not to be safely pushed out in the small threaded hole, and a good holding effect is achieved.
The motor 8 drives the connecting plate 2 to do sector motion, and the sector angle is determined by the moving range of the limiting knob 5 in the arc-shaped limiting groove 7.
