Abstract
The invention relates to a lifter, wherein one end of inner side of upper and lower frames (1, 2) are arranged with upper frame sliding groove (101) and lower frame sliding groove (201); two couples of connecting rods (3) are crossed, and connected via the cross point by hinge axle (4); two couples of connecting rods (3) are between the upper and lower frames (1, 2); one end of connecting rod (3) via fixed point axle (11) is connected to the upper and lower frames (1, 2), while another end via cam driven element is on the upper and lower sliding grooves (101, 201); the cam driven element (10) is matched with the sliding groove; the planes of upper and lower frames (1, 2) are vertical to the axle of lead screw (6); one end of upper frame (1) is mounted with lifting nut (9); one end of lead screw is through the lifting nut (9) and adjusting wheel (5) to be fixed on lower frame (2).
Description
Technical field
The present invention relates to the lifting machinery field, more specifically saying so is applicable to the adjustable a kind of lifting mechanism of surrounding edge machine operation podium level.
Background technology
Because the variety of mattress in the market, the inconsistency of mattress height, and the height of bench board is certain, in order to make the operator that a service platform that adapts to the differing heights bed mattress edge-enclosing be arranged, it is essential designing a kind of Height Adjustable service platform, and this Height Adjustable platform can be realized by lifting mechanism.
Summary of the invention
The present invention is in order to address the above problem, provide a kind of can be to the adjustable lifting mechanism of surrounding edge machine operation podium level.
It is as follows that the present invention addresses the above problem institute's employing technology: it comprises upper ledge, lower frame, the two pairs of connecting rods, hinge, screw mandrel, lifting nut, adjusting knurl; The inboard end of described upper ledge and lower frame is provided with upper ledge chute and lower frame chute respectively, and two pairs of connecting rods are the X cross-like respectively, and are connected as one by point of crossing by hinge, and two pairs of connecting rods place respectively between upper ledge and lower frame two sides; Two pairs of connecting rod one ends are connected with lower frame with upper ledge by the fixed pivot axle, and the other end is separately positioned on upper ledge chute and the lower frame chute by cam follower, cam follower and chute bearing fit, cam follower can be on chute sway; The plane of upper ledge and lower frame and screw mandrel axis are perpendicular, the end dress lifting nut of upper ledge, and an end of screw mandrel passes the lifting nut and the adjusting knurl that match with it and is fixed on the lower frame.Move up and down along screw mandrel by adjusting knurl scalable lifting nut, driven the up-and-down movement of upper ledge, cam follower is along the chute sway, and cam follower drivening rod one end sway realizes X-shaped connecting rod height adjustment up and down.
The lifting that the present invention is simple in structure, safe and reliable, can realize step-less adjustment has solved surrounding edge machine operation podium level and has regulated problem.

The specific embodiment
Shown in Fig. 1,2,3 and 4, the embodiment of the invention is made up of upper ledge 1, lower frame 2, two pairs of connecting rods 3, hinge 4, screw mandrel 6, screw mandrel cover 8, lifting nut 9, adjusting knurl 5, cam follower 10, fixed pivot axles 11.Upper ledge 1 and lower frame 2 inboard ends are provided with upper ledge chute 101 and lower frame chute 201 respectively, two pairs of connecting rods 3 are the X cross-like respectively, and connect as one by point of crossing by hinge 4, two pairs of connecting rods 3 place respectively between upper ledge 1 and lower frame 2 two sides, two pairs of connecting rod 3 one ends are connected with lower frame 2 with upper ledge 1 by fixed pivot axle 11, the other end is separately positioned on upper ledge chute 101 and the lower frame chute 201 by cam follower 10, cam follower and chute bearing fit, cam follower 10 can be on chute sway, the plane of upper ledge 1 and lower frame 2 and screw mandrel 6 axis are perpendicular, the one end dress lifting nut 9 of upper ledge 1, an end of screw mandrel 6 passes the lifting nut 9 and the adjusting knurl 5 that match with it and is fixed on the lower frame 2.Move up and down along screw mandrel 6 by adjusting knurl 5 scalable lifting nuts 9, driven the up-and-down movement of upper ledge 1, also drive the up-and-down movement of the service platform 7 above the upper ledge 1.Be with screw mandrel cover 8 outside the screw mandrel 6, screw mandrel cover 8 lower ends are fixed on the upper ledge 1.
Regulate adjusting knurl 5 and make screw mandrel 6 rotations, lifting nut 9 and screw mandrel 6 relative motions, because screw mandrel 6 is fixed on lower frame 2, lifting nut 9 drives upper ledge 1 up-and-down movement, cam follower 10 drives whole connecting rod 3 one end sway along the chute sway, has realized X-shaped connecting rod 3 height adjustments, played support fixation effect, realized the lifting of surrounding edge machine operation platform 7 upper ledge 1.
