Abstract
An automatic locking mechanism can include one or more annular elements having teeth facing each other or facing away from each other. The automatic locking mechanism can include a rod disposed between the annular elements. The rod can have one or more pins configured to interface with the teeth of the annular elements. The pins and the teeth are also configured to rotate the rod when the annular elements move relative to the rod. The rotation of the rod can toggle a hook end of the rod in a hook receptacle, which can change states of the locking mechanism.
Claims20
An automatic locking mechanism for a clamping device, comprising
- a first element,
- wherein the first element comprises one or more annular elements,
- wherein the one or more annular elements comprise multiple first teeth arranged around the one or more annular elements, wherein each first tooth of the multiple first teeth comprises a first valley area formed with a neighbor first tooth and a first slanting surface rising from the first valley area,
- wherein the one or more annular elements comprise multiple second teeth arranged around the one or more annular elements, wherein each second tooth of the multiple second teeth comprises a second valley area formed with a neighbor second tooth and a second slanting surface rising from the second valley area,
- wherein the first and second multiple teeth are spaced apart at a fixed distance;
- a second element,
- wherein the second element is disposed in the one or more annular elements of the first element,
- wherein the second element comprises one or more protruded elements for interfacing with the first and second slanting surfaces,
- wherein the interfacing of the one or more protruded elements with the first and second slanting surfaces is configured so that under a first force causing the one or more protruded elements to contact the first slanting surface, the one or more protruded elements moves along the first slanting surface to rest at the first valley area, which causes the second element to rotate a first angle in a rotating direction, and
- wherein the interfacing of the one or more protruded elements with the first and second slanting surfaces is configured so that under a second force causing the one or more protruded elements to contact the second slanting surface, the one or more protruded elements moves along the second slanting surface to rest at the second valley area, which causes the second element to rotate a second angle in the same rotating direction.
7 more elements
An automatic locking mechanism for a clamping device, comprising
- a first element,
- wherein the first element comprises a first annular element,
- wherein the first annular element comprises multiple first teeth arranged around the first annular element, wherein each first tooth of the multiple first teeth comprises a first valley area and a first slanting surface rising from the first valley area,
- wherein the first element comprises a second annular element,
- wherein the second annular element comprises multiple second teeth arranged around the second annular element, wherein each second tooth of the multiple second teeth comprises a second valley area and a second slanting surface rising from the second valley area,
- wherein the first and second annular elements are configured so that the multiple first teeth face the multiple second teeth;
- a second element,
- wherein the second element is disposed in the first and second annular elements of the first element,
- wherein the second element comprises a protruded element disposed between the first and second slanting surfaces of the first element for interfacing with the first and second slanting surfaces,
- wherein the protruded element and the first and second slanting surfaces is configured so that under a first force causing the protruded element to contact the first slanting surface, the protruded element moves along the first slanting surface to rest at the first valley area, which causes the second element to rotate a first angle in a rotating direction,
- wherein the at least a protruded element and the first and second slanting surfaces is configured so that under a second force causing the protruded element to contact the second slanting surface, the protruded element moves along the second slanting surface to rest at the second valley area, which causes the third element to rotate a second angle in the same rotating direction.
8 more elements
An automatic locking mechanism for a clamping device, comprising
- a first element,
- wherein the first element comprises an annular element,
- wherein the annular element comprises multiple first teeth arranged around the annular element, wherein each first tooth of the multiple first teeth comprises a first valley area and a first slanting surface rising from the first valley area,
- wherein the annular element comprises multiple second teeth arranged around the annular element, wherein each second tooth of the multiple second teeth comprises a second valley area and a second slanting surface rising from the second valley area, wherein the multiple first teeth and the multiple second teeth are disposed on opposite sides of the annular element;
- a second element,
- wherein the second element is disposed in the annular element of the first element,
- wherein the second element comprises two protruded elements configured so that the multiple first and second teeth are disposed between the two protruded elements,
- wherein the two protruded elements and the first and second slanting surfaces are configured so that under a first force causing a first protruded element of the two protruded elements to contact the first slanting surface, the first protruded element moves along the first slanting surface to rest at the first valley area, which causes the second element to rotate a first angle in a rotating direction,
- wherein the two protruded elements and the first and second slanting surfaces are also configured so that under a second force causing a second protruded element of the two protruded elements to contact the second slanting surface, the second protruded element moves along the second slanting surface to rest at the second valley area, which causes the second element to rotate a second angle in the same rotating direction.
