Description
Technical field
The utility model belongs to technical field of knitting machinery, particularly the portable plate door-opening mechanism of flat machine.
Background technology
The portable plate door-opening mechanism kind of existing flat machine is various, as used driven by motor cam mechanism, using curved bar structures etc.; The portable plate door-opening mechanism that uses driven by motor cam mechanism, its advantage is that the noise producing in integrated model work is smaller, but the processing cost of part is high, installs complicated; The portable plate door-opening mechanism of curved bar structures relies on moving object to suppress driving, and the working environment therefore producing in larger noise ，Shi textile mills at work is relatively made an uproar, and the person is injured to some extent.
Summary of the invention
The purpose of this utility model is for a kind of simple in structure, easily processing, the portable plate door-opening mechanism of the flat machine that the noise that produces in work is little are provided.
For this reason, the technical solution of the utility model is: the portable plate door-opening mechanism of flat machine, is characterized in that: it comprises portable plate, curved bar, the first fixed axis, the second fixed axis, slide track seat, plastic pulley, crashproof glue, rubber limited post and pillar; In the middle of described curved bar, be fixed on the first fixed axis, there are three lever arms; Described curved bar movable upper end Bei has a circular arc concave surface on top; A described curved bar lower end wherein side lever arm is flexibly connected with portable plate bottom by the second fixed axis; On the lever arm of described curved bar lower end opposite side, there is a vertical movement locus face, there is the confined planes of inclination below described movement locus face; The confined planes lower end of described curved bar connects an extension spring; In the middle of described portable plate, there is the first bearing pin and the second bearing pin; On described the first bearing pin, a torsion spring is installed, described torsion spring one end is near portable plate inwall, and the other end is pressed on the second bearing pin; Described the second bearing pin matches with the circular arc concave surface on curved bar top; Described slide track seat is arranged on pillar, and plastic pulley is equipped with in slide track seat bottom; Described plastic pulley is close to the movement locus face of curved bar; Described column bottom has crashproof glue, has rubber limited post on crashproof glue.
The utility model passes through to portable plate applied thrust, portable plate is rotated counterclockwise around the second fixed axis, thereby the second bearing pin is slipped into along the circular arc concave surface in curved bar, the torsion spring one end of installing on the first bearing pin is near portable plate inwall, the other end is pressed on the second bearing pin, thereby portable plate and curved bar link together; Otherwise, to portable plate, apply pulling force, open.
During the utility model work, driving downslide rail chair at lifting motor moves upward along pillar, plastic pulley on slide track seat rises along the movement locus face rolling of curved bar, be initially under the effect of tension spring tension, curved bar drives portable plate to turn clockwise around the first fixed axis, and when curved bar is about to hit rubber limited post, tension spring tension is close to zero, gravity by portable plate self is rotated further, until portable plate is all opened; Driving downslide rail chair at lifting motor moves downward along pillar, plastic pulley on slide track seat glides along the movement locus face rolling of curved bar, force curved bar to drive portable plate to be rotated counterclockwise around the first fixed axis, plastic pulley contacts with the movement locus face of curved bar all the time, the pulling force of extension spring also increases gradually, curved bar and plastic roller near together with do sliding motion, until slide track seat glides to limit, portable plate is closed, so no matter open mode or closure state, the noise of its generation is all very little.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment of the present utility model, be described in further detail.
Fig. 1 is the structural representation of the utility model while not working.
The structural representation of closure state when Fig. 2 is the utility model work.
The structural representation of open mode when Fig. 3 is the utility model work.
The specific embodiment
Referring to accompanying drawing.The present embodiment comprises portable plate 1, curved bar 5, the first fixed axis 6, the second fixed axis 7, slide track seat 12, plastic pulley 11, crashproof glue 10, rubber limited post 8 and pillar 13; In the middle of described curved bar 5, be fixed on the first fixed axis 6, there are three lever arms; Described curved bar has a circular arc concave surface 53 on 5 movable upper end Bei tops; A described curved bar 5 lower ends wherein side lever arm are flexibly connected with portable plate 1 bottom by the second fixed axis 7; On the lever arm of described curved bar 5 lower end opposite sides, have a vertical movement locus face 52, described movement locus face 52 has the confined planes 51 of inclination below; Confined planes 51 lower ends of described curved bar 5 connect an extension spring 9; In the middle of described portable plate 1, there is the first bearing pin 3 and the second bearing pin 4; On described the first bearing pin 3, a torsion spring 2 is installed, described torsion spring 2 one end are near portable plate 1 inwall, and the other end is pressed on the second bearing pin 4; Described the second bearing pin 4 matches with the circular arc concave surface 53 on curved bar 5 tops; Described slide track seat 12 is arranged on pillar 13, and plastic pulley 11 is equipped with in slide track seat 12 bottoms; Described plastic pulley 11 is close to the movement locus face 52 of curved bar 5; Described pillar 13 bottoms have crashproof glue 10, on crashproof glue 10, have rubber limited post 8.
As shown in Figure 1, when the present embodiment is not worked, give portable plate 1 applied thrust, portable plate 1 is rotated counterclockwise around the second fixed axis 7, thereby the second bearing pin 4 is slipped into along the circular arc concave surface 53 in curved bar 5, torsion spring 2 one end of installing on the first bearing pin 3 are near portable plate 1 inwall, and the other end is pressed on the second bearing pin 4, thereby portable plate 1 and curved bar 5 link together; Otherwise, apply pulling force to portable plate 1, open.
