Example 1
As shown in fig. 1 and 2, the self-limiting rotary pawl mechanism 5 of the present invention includes a vertical cantilever 501, a side stop 502, a pin 503, and a pawl 504; a round hole is formed in the lower portion of the vertical cantilever 501, a round hole is formed in the upper portion of the pawl 504, a pin shaft 503 penetrates through the round hole to connect the vertical cantilever 501 and the pawl, and the side stop block 502 is fixedly welded to the right lower side of the vertical cantilever 501; the upper end of the pawl 504 is semicircular, and the left and right sides are straight edges.
The vertical cantilever 501 is connected with the pawl 504 through a pin 503, and the pawl 504 can rotate around the pin 503; when the pawl 504 rotates clockwise around the pin 503 to a certain position, the upper right of the pawl 504 contacts with the side stop block 502, and the rotation of the pawl 504 is limited; the pawl 504 cannot rotate counterclockwise around the pin 503 due to the position of the side stop 502, so the pawl mechanism has a self-limiting function.
Example 2
The left side of the pawl 504 is a straight line segment, the right side is the combination of a straight line segment and an oblique line segment, and the left and right straight line segments are tangent to a semicircle at the upper end thereof; the circular hole in the pawl 504 is eccentrically disposed with respect to the symmetrical center line of the semicircle at the upper end thereof.
Wherein, the upper end of the right oblique line segment of the pawl 504 is connected with the straight line segment, and the lower end inclines to the left side. Thus, when the storage box 9 contacts the right side of the pawl 504, the storage box 9 only makes line contact with the pawl rather than surface contact, and therefore the storage box 9 is protected and abrasion of the pawl 504 is reduced.
The circular hole in the pawl 504 is eccentrically positioned with respect to the semi-circular symmetrical center line of its upper end so that when the right side of the pawl 504 is forced to rotate clockwise, its upper portion is more likely to contact the side stop 502, and the distance of eccentricity can be determined according to the rotation angle set by the pawl mechanism.
And simultaneously, the utility model discloses from spacing gyration pawl mechanism simple structure, it is convenient to maintain, and the cost is lower, but wide use in simple link of controlling.
