Detailed Description
The present invention is described herein with reference to the accompanying drawings, and it is to be understood that the present invention is not limited to the illustrations, but is intended to cover various changes and modifications within the spirit and scope of the invention.
Example 1
As shown in fig. 1-9, a quick limiting mechanism comprises an outer sleeve 1, a positioning plate 2 and a locking rod 3;
the outer sleeve 1 is of a hollow structure, the outer wall of one end is provided with threads, the end face of the end provided with the threads is also provided with an outer sleeve rotating hand wheel 1.1, the other end is uniformly provided with 4 limiting block telescopic holes 1.2 along the circumferential direction, and the inner wall is provided with releasing limiting holes 1.3 and locking limiting holes 1.4 which are linearly arranged along the length direction of the outer sleeve 1;
the center of the plate surface of the positioning plate 2 is provided with a positioning plate center connecting screw hole 2.2, the outer sleeve 1 is screwed in the positioning plate center connecting screw hole 2.2 of the positioning plate 2 through threads on the outer wall, and a positioning pin 2.1 vertical to the plate surface of the positioning plate 2 is arranged along the circumference of the positioning plate center connecting screw hole 2.2;
the locking rod 3 is cylindrical, one end of the locking rod 3 is arranged in the outer sleeve 1, 4 limiting blocks 3.3 are uniformly arranged at one end arranged in the outer sleeve 1 along the circumference, the limiting blocks 3.3 are movably arranged in the limiting block telescopic holes 1.2, 4 protrusions 3.1 are uniformly arranged on the outer wall of one end of the locking rod 3, which is provided with the limiting blocks 3.3, each protrusion 3.1 is provided with a pin hole, and each limiting block 3.3 is also provided with a pin hole; the limiting block 3.3 is movably connected with the bulge 3.1 through a connecting rod 3.2; the other end of the locking rod 3 extends out of the end face of the outer sleeve 1, a collision bead 3.4 is further arranged on the side face of the cylinder of the locking rod 3, the collision bead 3.4 is located in the locking limiting hole 1.4 in a limiting state, the collision bead 3.4 is located in the releasing limiting hole 1.3 in a releasing state, and a pull ring hole and a pull ring are further radially formed in one end, extending out of the end face of the outer sleeve 1, of the locking rod 3.
When the positioning device is used, firstly, 4 positioning pins 2.1 of the positioning plate 2 are inserted into the positioning holes on the surfaces of the 4 limited parts, so that the relative positions of the limited parts in a plane parallel to the positioning plate 2 are fixed, and the connecting screw hole 2.2 in the center of the positioning plate 2 aligns to the gap between the limited parts.
Subsequently, the outer sleeve 1 is screwed into the central connecting screw hole 2.2 of the positioning plate and then inserted into the gap between the limited pieces. At this time, the lock lever 3 is pushed so that the collision bead 3.4 is fed from the release stopper hole 1.3 to the lock stopper hole 1.4, and the lock lever 3 is fixed again. In the process of feeding the collision bead 3.4 from the releasing limiting hole 1.3 to the locking limiting hole 1.4, the locking rod 3 is pushed in the axial direction, the connecting rod 3.2 can be linked, and the limiting block 3.3 is pushed out of the limiting block telescopic hole 1.2 in the radial direction, so that the limiting block 3.3 and the positioning plate 2 act together, and the relative position of the limiting block in the direction perpendicular to the positioning plate 2 is fixed.
When the spacing is required to be relieved, the pull ring is pulled outwards, the collision bead 3.4 retreats from the locking spacing hole 1.4 to the releasing spacing hole 1.3 and is fixed, the locking rod 3 retreats axially, the connecting rod 3.2 is linked, the spacing block 3.3 is further pulled back to the spacing block telescopic hole 1.2 along the radial direction, and then the positioning pin 2.1 of the positioning plate 2 is pulled out from the positioning hole on the surface of the spacing block, so that the spacing can be relieved quickly.
Example 2
The present embodiment is different from embodiment 1 in that: the face of the end face, far away from the locking rod 3, of the limiting block 3.3, of the end face, extending out of the outer sleeve 1 is an inclined face, correspondingly, the inner wall face of the limiting block telescopic hole 1.2, contacted with the inclined face of the limiting block 3.3, is also an inclined face, namely, the cross section of the limiting block telescopic hole 1.2 is in a right-angled trapezoid shape, and therefore the self-locking phenomenon caused by unreasonable design and assembly parameters can be effectively avoided. It can be easily inferred by those skilled in the art that the normal direction of the inclined surface is biased toward the end of the locking lever 3 extending out of the outer sleeve 1, rather than biased toward the end of the locking lever 3 extending out of the outer sleeve 1.
In addition, the release limiting hole 1.3 and the locking limiting hole 1.4 can be replaced by annular release limiting grooves and locking limiting grooves which are arranged along the circumference of the inner wall of the outer sleeve 1, and the structure is more beneficial to processing and forming.
