FIG. 1 is a schematic view of the overall structure of the buffering strut of the present invention;
FIG. 2 is a sectional view of the buffering strut structure of the present invention;
the objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.
Detailed Description
Referring to fig. 1 and 2, the anti-rotation buffer support rod provided in this embodiment includes a fixed rod 1, a through guide groove 11 is formed in the fixed rod 1, a movable rod 2 connected to an external suction cup (not shown in the figure) is installed at one end of the guide groove 11, a connection cap 3 connected to an external vacuum air pipe connector (not shown in the figure) is installed at the other end of the guide groove 11, the connection cap 3 abuts against the movable rod 2 through an elastic member 4, and the elastic member 4 is provided as a spring; the movable rod 2 comprises a sliding part 21 which is in sliding connection with the guide groove 11, two mounting holes 22 are symmetrically formed in the outer side surface of the sliding part 21, a sliding block 23 is respectively mounted in each mounting hole 22, and sliding grooves 12 which are matched with the sliding blocks 23 one by one are formed in the inner side surface of the guide groove 11 along the length direction of the guide groove; the outer diameter of the sliding part 21 is larger than the outer diameter of the main body of the movable rod 2, an annular limiting table 13 is arranged at the end part of the guide groove 11, and the main body of the movable rod 2 movably penetrates through the annular limiting table 13; the outer side surface of the fixed rod 1 is provided with a thread structure 14 for fixedly mounting the buffering support rod.
It should be noted that, this embodiment sets up traditional buffering branch into dead lever 1 and movable rod 2 of relative slidable mounting, when carrying out the vacuum adsorption operation, can keep dead lever 1 motionless, only carries out the product through the flexible of movable rod 2 and adsorbs to prevent to stretch out and draw back and take place to buckle with the vacuum tube that dead lever 1 is connected, guarantee the vacuum adsorption power.
Further, this embodiment is external with traditional spring, sets up to spring built-in structure, prevents that the metal powder that the friction produced between spring and the buffering branch from dropping the product on, influences the use of product. Specifically, through the guide way 11 that process through in dead lever 1, the movable rod 2 and the connection cap 3 through the spring butt are installed respectively to both ends, and when the telescopic motion was done to movable rod 2 in guide way 11, carry out the compression of spring, even spring and 11 inner walls of guide way friction can produce metal powder, nevertheless because be vacuum negative pressure state in the guide way 11, metal powder can be taken out from connecting cap 3, prevents that it from dropping on the product. Meanwhile, in the embodiment, the sliding groove 12 is processed in the guide groove 11, the sliding block 23 is installed on the movable rod 2, and the movable rod 2 and the fixed rod 1 are limited to rotate while sliding relatively through the sliding fit of the sliding block 23 and the sliding groove 12. It should be noted that, when the chute 12 is processed to be smooth, polishing is required, and the slider 23 is provided as a sliding ball so that the movable rod 2 can move up and down smoothly.
