Preferably, in the anti-falling mechanism of lifting table, rope is two, every corresponding four wheel flutters of rope, and connect five swinging gear.
Preferably, in the anti-falling mechanism of lifting table, four wheel flutters are positioned at rectangular four angles, and the line of centers of oblong Width overlaps with the line of centers of lifting table table top length direction; On the line of centers that in five swinging gear, is arranged on lifting table table top length direction, in all the other four, two arrange along lifting table table top length direction, be positioned on the line of centers of oblong length direction simultaneously, and symmetrical about lifting table table top length direction line of centers; Two other arranges along lifting table mesa width direction, and symmetrical about lifting table table top length direction line of centers.
Preferably, in the anti-falling mechanism of lifting table, telescoping cylinder is connected with normal-open electromagnetic valve.
Preferably, in the anti-falling mechanism of lifting table, telescoping cylinder is double acting Gas spring cylinder.
The beneficial effects of the utility model:
Telescoping cylinder is connected with a plurality of latch segments with swinging gear by rope, under the motion of flexible telescoping cylinder, drive swinging gear motion, and then the location status of control latch segment, when lifting table arrives a certain floor, a part for latch segment is inserted in the default crack of floor, when lifting table will continue to move, latch segment is fully retracted in platform table top.
Accompanying drawing explanation
Fig. 1 is the structural representation of the selected embodiment of the utility model.
In figure 1, telescoping cylinder, 2, wheel flutter, 3, lifting table table top, 4, latch segment, 5, steering track rod, 6, rope, 7, connecting panel, 8, normal-open electromagnetic valve, 9, source of the gas, 10, rotating shaft, the line of centers of a, lifting table table top length direction, the line of centers of b, oblong length direction.
The specific embodiment
For the ease of those skilled in the art, better understand the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further details, following is only the exemplary protection domain of the present utility model that do not limit.
With reference to accompanying drawing 1, a kind of anti-falling mechanism of lifting table, comprise telescoping cylinder 1, above rope 6, a plurality of swinging gear and an a plurality of latch segment 4, rope 6 is connected with telescoping cylinder 1 and swinging gear, latch segment 4 is rotationally connected with lifting table table top 3, a swinging gear of each latch segment 4 corresponding connection, telescoping cylinder 1 pulls by swinging gear and drives latch segment 4 to stretch out or retraction lifting table table top 3 through rope 6 when flexible.
In the present embodiment, anti-falling mechanism also includes connecting panel 7, and telescoping cylinder 1 is connected with connecting panel 7, and rope 6 one end are connected with connecting panel 7, and the other end is connected on connecting panel 7 after more than one wheel flutter 2 connects a plurality of swinging gear.
In the present embodiment, telescoping cylinder 1 is in the center of lifting table table top 3.
In the present embodiment, swinging gear and latch segment 4 are arranged symmetrically with about lifting table table top line of centers.
In the present embodiment, swinging gear is two steering track rods 5, and each steering track rod 5 one end is fixedly connected with rope 6, and the other end and latch segment 4 are articulated as one, and latch segment 4 is connected with lifting table table top 3 by rotating shaft 10.
In the present embodiment, rope 6 is two, every corresponding four wheel flutters 2 of rope 6, and connect five swinging gear.Four wheel flutters 2 are positioned at rectangular four angles, and the line of centers of oblong Width overlaps with the line of centers a of lifting table table top length direction; On the line of centers a that in five swinging gear, is arranged on lifting table table top length direction, in all the other four, two arrange along lifting table table top length direction, the line of centers b that is simultaneously positioned at oblong length direction is upper, and symmetrical about the line of centers a of lifting table table top length direction; Two other arranges along lifting table mesa width direction, and symmetrical about the line of centers a of lifting table table top length direction.
