Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-3, the magnetic-type mechanism for picking of one of the present utility model, comprise pilot bar 1, coil spring 2, guide holder and mount pad, guide holder and mount pad are the hollow housing of upper and lower opening.
Pilot bar 1 is located in coil spring 2, and the top of pilot bar 1 has rib 11, and the bottom of pilot bar 1 is provided with pin 12, and pin 12 to be plugged on pilot bar 1 sidewall and to stretch out.
The upper end of coil spring 2 is against the rib 11 of pilot bar 1, and the lower end abutment mount pad of coil spring 2, the bottom of pilot bar 1 is fixed with a magnetite 3.
The sidewall of guide holder is provided with guide groove, guide groove comprises two elongated slots 421 and two short grooves 422, each elongated slot 421 and the spaced setting of short groove 422, and led by skewed slot 423 and are interconnected in the bottom of adjacent elongated slot 421 and the bottom of short groove 422, skewed slot 423 totally four, the bottom of each skewed slot 423 tilts from shallow to deep and the bottom angled direction of all skewed slots 423 is consistent, and as Figure 1-3, the bottom of skewed slot 423 is all inclined upwardly in the counterclockwise direction from shallow to deep.
The top of elongated slot 421 is higher than the top of short groove 422, and the top of the top of elongated slot 421 and short groove 422 is along the absorption distance of the height difference H >=magnetite 3 of pilot bar 1 length direction; Pin 12 is arranged in guide groove; Pilot bar 1 is located in guide holder, and guide holder is fixedly mounted on mount pad inside.
Guide holder comprises guide holder 4, spacing sleeve 5 and lower guide holder 6, upper guide holder 4 comprises first fixing body 41 on top and the first director 42 of bottom, first fixing body 41 offers the first notch 411, elongated slot 421 and short groove 422 are opened on the sidewall of the first director 42; Lower guide holder 6 comprises on second director 61 on top and the second fixing body 62, second fixing body 62 of bottom and offers the second notch 621; Spacing sleeve 5 top and bottom all have projection 51, the projection 51 at top and the first notch 411 grafting, the projection 51 of bottom and the second notch 621 grafting, and the first fixing body 41 and the second fixing body 62 are all fixed with mount pad.Second director 61 top offers four grooves 611, and the direction of tilt of described groove 611 is contrary with the direction of tilt of skewed slot 423, and as Figure 1-3, the bottom of groove 611 is downward-sloping from deep to shallow all in the counterclockwise direction.Each groove 611 lays respectively at an elongated slot 421 or short groove 422 below along pilot bar 1 length direction.
Mount pad comprises the upper mount pad 7, middle base 8 and the lower mount pad 9 that are connected successively, mount pad 7 in the lower end abutment of coil spring 2, first fixing body 41 is fixed with upper mount pad 7, second fixing body 62 is fixed with lower mount pad 9, magnetite 3 moves up and down in lower mount pad 9, namely magnetite 3 is in lower mount pad 9 inside always, and magnetite 3 can be prevented like this to be damaged.
Working process of the present utility model is as follows:
During assumed initial state, pin 12 coordinates with elongated slot 421 top, so by the bottom of lower mount pad 9 against outside desktop or external bracing body, and promote pilot bar 1, pin 12 on pilot bar 1 is moved down, coil spring 2 by compression, after pin 12 leaves elongated slot 421 simultaneously, first contacts with the bottom surface of groove 611.Continue to promote pilot bar 1 downward, pin 12 moves down along the bottom surface of groove 611, and now pin 12 moves to the below of skewed slot 423.Unclamp pilot bar 1, due to the screen resilience effect of coil spring 2, pin 12 can move up along skewed slot 423, thus move in an adjacent short groove 422, and coordinate with short groove 422 top, as shown in Figure 2, now magnetite 3 is positioned at nadir, magnetite 3 is nearest with parts to be drawn, and within absorption distance, parts to be drawn are in suction status.Next time again by the bottom of lower mount pad 9 against outside desktop or external bracing body, and promote pilot bar 1, it is downward that pin 12 leaves short groove 422 summit, first contacts with the bottom surface of another groove 611.Continue to promote pilot bar 1 downward, pin 12 moves down along the bottom surface of groove 611, and now pin 12 moves to the below of skewed slot 423.Unclamp pilot bar 1, due to the screen resilience effect of coil spring 2, pin 12 can move up along skewed slot 423, thus move in an adjacent elongated slot 421, and coordinate with elongated slot 421 top, as shown in Figure 3, now magnetite 3 is positioned at vertex, farthest, outside absorption distance, parts to be drawn are in disengaged position for magnetite 3 and the parts distance that will draw.
Suppose that two elongated slots 421 and two short grooves 422 are well-distributeds, namely adjacent elongated slot 421 top and short groove 422 head clearance 90 °, so pilot bar often rotates 90 °, and magnetite 3 completes the conversion of a disengaged position and suction status.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
