The lifting device is characterized in that a through hole is formed in a table top mechanism, a vertical rod part is arranged in the through hole in a penetration way, the table top mechanism comprises two symmetrical vertical guide rails arranged at the lower part of the table top mechanism, positioning wheels and movable pulleys are arranged on the two vertical guide rails respectively, the two movable pulleys are connected through a cross shaft, a lifting motor is arranged on the table top mechanism, an output shaft of the lifting motor is connected with the cross shaft, a first guide wheel positioned above the movable pulleys and a second guide wheel connected with the vertical rod part are further arranged on the table top mechanism; a steel rope sequentially bypasses the movable pulleys, the first guide wheel and the second guide wheel; one end of the steel rope is fixed on the vertical rod part and the other end of the steel rope is fixed on the table top mechanism. The lifting device is reasonable in structure, convenient to mount and maintain and steady and quiet to lift.

Description

A kind of lowering or hoisting gear that makes up optometry platform transverse arm mechanism
Technical field
The utility model relates to a kind of optometry equipment parts, especially a kind of lowering or hoisting gear that makes up optometry platform transverse arm mechanism.
Background technique
The lifting device structure that has combination optometry platform Top Crossbeam mechanism now is comparatively complicated, and maintenance and installation are inconvenient, and relatively poor in the lifting process stationarity, and lifting process is easy to generate noise, influences comfort.
The model utility content
The utility model provides a kind of lowering or hoisting gear that makes up optometry platform transverse arm mechanism at the defective that prior art exists, and can reduce operating noise, effectively promotes the stability of transverse arm mechanism lifting, and simplified structure, reduces cost.
For this reason, the utility model is taked following technological scheme: a kind of lowering or hoisting gear that makes up optometry platform transverse arm mechanism, comprise on vertical rod parts and the table top mechanism vertical rod parts transverse arm mechanism is set, it is characterized in that having through hole in the described table top mechanism, wear the vertical rod parts in the through hole, this table top mechanism comprises the vertical guide of two symmetries in its underpart, article two, on the vertical guide positioning wheel and movable pulley are housed respectively, two movable pulleys join by a transverse axis, in the described table top mechanism lifting motor is set, the output shaft of lifting motor and described transverse axis join, also be provided with first upper saw pulley that is positioned at the movable pulley top and second upper saw pulley that joins with the vertical rod parts in the described table top mechanism, one steel cable is walked around movable pulley successively, first upper saw pulley, second upper saw pulley, steel cable one end is fixed on the vertical rod parts, and the other end is fixed in the table top mechanism.The output shaft of lifting motor orders about movable pulley oscilaltion in slide rail, drives first upper saw pulley and the rotation of second upper saw pulley successively by steel cable, and drives the oscilaltion of vertical rod parts by second upper saw pulley, reaches the purpose of regulating transverse arm mechanism high and low position.
As preferably, described positioning wheel setting-in makes in the lifting process each positioning parts firm in orbit.
As preferably, described table top mechanism bottom is provided with the base of supporting bable tops mechanism, lifter board face stability.
As preferably, described lifting motor is the straight line lifting motor.
The utility model constitutes a kind of Motorized lift device that is used for the lifting of optometry platform Top Crossbeam mechanism by straight line lifting motor, a plurality of movable pulley and upper saw pulley, and is rational in infrastructure, easy to installation and maintenance, and lifting is steadily quiet.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. transverse arm mechanism 2. vertical rod parts 3. table top mechanisms 4. output shafts, 5. steel cables, 6. lifting motors, 7. transverse axis 8. movable pulleys 9. guide rails 10. first upper saw pulleys 11. second upper saw pulleys 12. bases.
Embodiment
The lowering or hoisting gear of combination optometry platform transverse arm mechanism as shown in Figure 1 comprises vertical rod parts 2 and table top mechanism 3, has through hole in the table top mechanism 3, wears vertical rod parts 2 in the through hole, is nested with a transverse arm mechanism 1 on the vertical rod parts 2.This table top mechanism 3 comprises on 9, two vertical guide 9 of vertical guide of two symmetries in its underpart is equipped with positioning wheel and movable pulley 8 respectively, and positioning wheel is inlaid in the slide rail 9.Two movable pulleys 8 join by transverse axis 7, straight line lifting motor 6 is set in the table top mechanism 3, the output shaft 4 and the transverse axis 7 of lifting motor 6 join, also be provided with first upper saw pulley 10 that is positioned at movable pulley 8 tops and second upper saw pulley 11 that joins with vertical rod parts 2 in the table top mechanism 3, and walk around movable pulley 8, first upper saw pulley 10, second upper saw pulley 11 successively by steel cable 5, steel cable 5 one ends are fixed on the vertical rod parts 2, and the other end is fixed in the table top mechanism 3.Table top mechanism 3 bottoms also connect the base 12 of a supporting bable tops mechanism 3.
Output shaft by lifting motor during lifting orders about movable pulley oscilaltion in slide rail, drive first upper saw pulley and the rotation of second upper saw pulley successively by steel cable, and, reach the purpose of regulating transverse arm mechanism high and low position by the oscilaltion of second upper saw pulley drive vertical rod parts.The utility model constitutes a kind of Motorized lift device that is used for the lifting of optometry platform Top Crossbeam mechanism by straight line lifting motor, a plurality of movable pulley and upper saw pulley, and is rational in infrastructure, easy to installation and maintenance, and lifting is steadily quiet.
It needs to be noted, the mode of the foregoing description only limits to describe embodiment, but the utility model is confined to aforesaid way incessantly, therefore and those skilled in the art can modify in not breaking away from scope of the present utility model in view of the above easily, and scope of the present utility model should comprise the principle that the utility model discloses and the maximum magnitude of new feature.
