It is mounted on fuselage to seat, both ends are equipped with second oil-free bushing fixed by the second limited block, and second limited block is same
Sample plays the position-limiting action up and down of lifting process；The lower limit mechanical switch is mounted on fuselage by switch base；On described
Limit mechanical switch is installed on fuselage；
Structure is consistent at left and right sides of the driving unit, mainly includes cylinder, rack gear, rack bar side lower position block, rack gear
Side upper limit position block, load platform, pin shaft, bearing pin side lower position block, bearing pin side upper limit position block；
The cylinder is mounted on fuselage, and cylinder push-rod is connect with load platform middle position；The load platform both ends
It is separately installed with rack bar side lower position block and bearing pin side lower position block；The rack gear lower end is equipped with rack bar side upper limit position block；Institute
It states pin shaft lower end and bearing pin side upper limit position block is installed；
The gear unit mainly includes gear, the first axle sleeve, the second axle sleeve, transmission shaft, shaft coupling, flat key；The tooth
Wheel is connected by flat key, the first axle sleeve, the second axle sleeve and transmission shaft, and two sides transmission shaft is connected by shaft coupling, so that two sides reach
To the effect of Synchronous Transmission.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the utility model elevator portion cross-sectional view；
Specific embodiment
Referring to figs. 1 to Fig. 2, that show the specific structures of the preferred embodiment of the utility model.It below will specifically
The design feature of bright each element of the utility model.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of elevating mechanism, including gear unit,
Driving unit, case unit.
The gear unit is connect by bearing block 201 with case unit, and the driving unit passes through rack gear 101 and transmission
The gear 305 of unit engages, to realize the load platform synchronization lifting on the driving unit of two sides.
Structure is consistent at left and right sides of the case unit comprising fuselage 204, rack gear guide holder 207, pin shaft guide holder
208, the first limited block 205, the second limited block 206, bearing block 201, switch base 203, upper limit mechanical switch 202, lower limit
Mechanical switch 209；
The rack gear guide holder 207 is mounted on fuselage 204, and upper and lower ends are equipped with the first oil-free bushing 201, and described the
One oil-free bushing 201 is fixed by the first limited block 205；First limited block 205 plays the bound of lifting process simultaneously
Position effect；The pin shaft guide holder 208 is mounted on fuselage 204, and both ends are equipped with second fixed by the second limited block 206
Oil-free bushing 211, second limited block 206 equally play the position-limiting action up and down of lifting process；The lower limit machinery is opened
209 are closed to be mounted on fuselage by switch base 203；The upper limit mechanical switch 202 is installed on fuselage 204；
Structure is consistent at left and right sides of the driving unit, and the cylinder 103 is mounted on fuselage 204, the push rod of cylinder 103
It is connect with 106 middle position of load platform；106 both ends of load platform are separately installed with rack bar side lower position block 107 and pin
Axis side lower position block 108；101 lower end of rack gear is equipped with rack bar side upper limit position block 102；105 lower end of pin shaft is equipped with
