Abstract
A kind of novel opposite opened folding cover plate comprises frame, and a returning face plate is respectively established on the right the second from left limit of frame, and returning face plate is movably fixed on frame by the rotating shaft of lower end, and rotating shaft one end is fixed with sprocket wheel through frame, on it, and two are even connected by chain between wheel; Returning face plate described in one of them is provided with pull bar, conductive bar, ratchet opened lock fixed pole and is located at and turns dog end, in the middle of described conductive bar, hinge joint is on returning face plate, one end and conductive bar one end of described pull bar are hinged, the conductive bar other end connects ratchet opened lock fixed pole, conductive bar can be driven to rotate by pull bar, conductive bar is rotated and is driven ratchet opened lock fixed pole to rotate, and ratchet opened lock fixed pole rotational is opened or locking ratchet.The utility model has the advantage of, laborsaving, at the uniform velocity can beat and close or close.
Description
Technical field
The utility model relates to a kind of opposite opened folding cover plate, particularly a kind of laborsaving, opposite opened folding cover plate at the uniform velocity.
Prior art
Hang on thing hole at three ringwalls, use that monolithic cover plate is folding to be opened, the counterweight of use is comparatively large, and effective vent can be much less than actual aperture, and guardrail height is difficult to ensure.Due to the restriction in principle, when opening opening, the speed that cover plate is opened can be more and more faster, this is because cover plate and weight all constantly accelerate to cause under the effect of inertia.For the cover plate that centre is folding, after unlatching, there is certain dead angle, during closedown, need larger active force.
Summary of the invention
The technical problem of the utility model solution is, provides a kind of laborsaving, at the uniform velocity opposite opened folding cover plate, is specially adapted to the thing hole of three ringwalls.
The technical scheme solving above technical problem is, a kind of novel opposite opened folding cover plate comprises frame, a returning face plate is respectively established on the right the second from left limit of frame, returning face plate is movably fixed on frame by the rotating shaft of lower end, rotating shaft one end is fixed with sprocket wheel through frame, on it, and two are even connected by chain between wheel;
Returning face plate described in one of them is provided with pull bar, conductive bar, ratchet opened lock fixed pole and is located at and turns dog end, in the middle of described conductive bar, hinge joint is on returning face plate, one end and conductive bar one end of described pull bar are hinged, the conductive bar other end connects ratchet opened lock fixed pole, conductive bar can be driven to rotate by pull bar, conductive bar is rotated and is driven ratchet opened lock fixed pole to rotate, and ratchet opened lock fixed pole rotational is opened or locking ratchet.
Further, returning face plate lower end is provided with counterweight.
Further, described returning face plate is provided with fence locking.
Further, cover plate also comprises hydraulic push rod, and hydraulic push rod one end is connected on returning face plate, and the other end is connected on frame.
Further, conductive bar is connected with ratchet opened lock fixed pole by active lever, and in the middle of described active lever, hinge joint is on returning face plate, and one end and conductive bar link, and the other end is connected with ratchet opened lock fixed pole by hard bar.
The utility model has the advantage of, utilize existing folding cover plate basis on to locking ratcheting operation mechanism improve, make more convenient operation.Ratchet opened lock fixed pole is used for pull bar, removes this step of independent open detent from, and when only pulling pull bar, plate renovated by cover plate is just can open state.Hydraulic push rod auxiliary cover plate open and maintain that cover plate is opened, closing velocity stable.Chain drive ensure that side cover plate synchronization action.The unlatching of cover plate, closedown only need an action to complete.
accompanying drawing explanation
Be described further below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side diagram of the present utility model.
Fig. 3 is the enlarged drawing of P point in this Fig. 1.
As figure, frame 1, returning face plate 2, rotating shaft 3, sprocket wheel 4, chain 5, pull bar 6, conductive bar 7, ratchet opened lock fixed pole 8, ratchet 9, ratchet opened lock fixed pole 10, counterweight 10, fence locking 11, hydraulic push rod 12, active lever 13, hard bar 14.
detailed description of the invention
As in Fig. 1, a kind of novel opposite opened folding cover plate comprises frame 1, a returning face plate 2 is respectively established on the right the second from left limit of frame 1, returning face plate 2 is movably fixed on frame 1 by the rotating shaft 3 of lower end, returning face plate 2 lower end is also provided with counterweight 10, rotating shaft 3 one end is fixed with sprocket wheel 4 through frame 1, on it, as in Fig. 2, is connected between two sprocket wheels 4 by chain 5;
Returning face plate 2(described in one of them is returning face plate initiatively) be provided with pull bar 6, conductive bar 7, ratchet opened lock fixed pole 8, fence locking 11, hydraulic push rod 12, and be located at the ratchet 9 of rotating shaft 3, returning face plate 2 upper end is provided with in the middle of conductive bar 7 and links on returning face plate 2, fence locking 11 is located at the upper end of returning face plate 2, one end and conductive bar 7 one end of pull bar 6 are hinged, conductive bar 7 other end is connected with ratchet opened lock fixed pole 10 by active lever 13, as in Fig. 3, in the middle of active lever 13, hinge joint is on returning face plate 2, one end and conductive bar 7 link, the other end is by linking in the fixing hole of hard bar 14, hard bar 14 is located at ratchet opened lock fixed pole 10 and connects, conductive bar 7 can be driven to rotate by pull bar 6, conductive bar 7 is rotated and is driven active lever 13 to rotate (taking anchor point as turning cylinder), active lever 13 is rotated by hard bar 14 drive activity ratchet open locking bar 10, ratchet opened lock fixed pole 10 rotational is opened or locking ratchet 9, hydraulic push rod 12 one end is connected on returning face plate 2, and the other end is connected on frame 1.
