Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a quick locking piece, as shown in fig. 1, including stop pin 1, stop pin 1 has and is shaft-like pin 102, has seted up slot 4 at the tip of pin 102, inserts at slot 4 department of interlude and is equipped with lockplate 3 that is used for realizing the locking, as shown in fig. 2, sets up the locking strip hole 7 that runs through the plate body on lockplate 3's the plate body, and locking strip hole 7 sets up and is the slope form along the length direction of plate body.
Meanwhile, the end of the pin rod 102 is notched by the insertion slot 4, so that the symmetrically distributed locking lugs 5 are formed on two sides of the insertion slot 4, the locking lugs 5 and the pin rod 102 are integrally formed, the symmetrically distributed locking lugs 5 are respectively designated as a first locking lug and a second locking lug, the first locking lug and the second locking lug are respectively provided with a straight pin hole 6, when the locking plate 3 is inserted into the insertion slot 4, a straight pin penetrates into the locking strip hole 7 and the straight pin hole 6, the locking plate 3 automatically falls under the guiding action of the locking strip hole 7, then is matched with a self-locking hole 13 correspondingly arranged on the movable sleeve 9, and quick locking is realized by a wedging and fixing mode.
The straight pin hole 6 and the locking strip hole 7 are used for locking the straight pin together, in order to enable the straight pin to smoothly penetrate into the hole, the straight pin hole 6 is set to be a round hole, the circle centers of the straight pin hole formed in the first locking lug and the straight pin hole formed in the second locking lug are all located on the same straight line, and therefore the straight pin is enabled to keep penetrating linearly.
In addition, in order to prevent the locked locking pin from separating from the fixed shaft 8 and the movable sleeve 9, the locking pin 1 further comprises a limiting circular plate 101, the limiting circular plate 101 is fixed at one end of the pin rod 102, and the diameter of the limiting circular plate 101 is larger than that of the locking holes formed in the fixed shaft 8 and the movable sleeve 9, so that the limiting effect is realized.
The utility model also discloses a shaft assembly, including fixed axle 8, movable sleeve 9, as shown in fig. 3, fixed axle 8 is pegged graft mutually with movable sleeve 9 and is realized connecting the locking through novel disclosed quick locking piece.
The method specifically comprises the following steps: as shown in fig. 3, a shaft head 10 is formed at the end of the fixed shaft 8, an inner locking hole 11 is formed on the shaft head 10, and an outer locking hole 12 is formed on the movable sleeve 9; as shown in fig. 4 and 5, a self-locking groove 13 which is engaged with the locking plate 3 is formed in an outer wall of the movable sleeve 9. Therefore, as shown in fig. 6, when the fixing shaft 8 is inserted into the movable sleeve 9 through the shaft head 10, the inner locking hole 11 is aligned with the outer locking hole 12, the locking pin 1 of the quick locking piece is inserted into the aligned inner locking hole 11 and the aligned outer locking hole 12, the locking plate 3 is inserted into the slot 4, the straight pin is synchronously inserted into the straight pin hole 6 and the locking bar hole 7, the straight pin needs to contact with the lower half part of the locking bar hole 7 first, then the locking plate 3 slides downwards under the guiding action of the obliquely arranged locking bar hole 7 until the top end of the locking bar hole 7 abuts against the straight pin, and meanwhile, the locking plate 3 is clamped into the self-locking groove 13 to realize locking.
