Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a schematic structural view of a preferred embodiment of a piston ring with a limiting mechanism according to the present invention;
fig. 2 is an enlarged view of a portion a in fig. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, an embodiment of the present invention includes:
a piston ring with a spacing mechanism, comprising: piston ring body 1, piston ring body 1's one end has first ladder link 2, piston ring body 1's the other end has second ladder link 3, but first ladder link 2 and second ladder link 3 cross-over cooperation, first ladder link 2 and 3 cross-over of second ladder link overlap, coincide each other.
Be provided with stop gear on the first step link 2, stop gear includes: stopper 4, slide 5, spring 6, first round hole 7 and second round hole 8, first round hole 7 and the second round hole 8 that are linked together are seted up to the head of first step link 2, the top at first round hole 7 is seted up to second round hole 8, the one end fixed connection of spring 6 is in the bottom surface of first round hole 7, the other end and the slide 5 fixed connection of spring 6, slide 5 slides in first round hole 7, stopper 4 is fixed to be set up at the upper surface of slide 5, set up on the second step link 3 with stopper 4 matched with spacing groove 9.
The diameter of the second round hole 8 is smaller than that of the first round hole 7, the sliding plate 5 is of a circular structure, and the diameter of the sliding plate 5 is larger than that of the second round hole 8, so that the sliding plate 5 is limited to slide in the first round hole 7.
