Abstract
The utility model relates to an external set electric control stepless zoom for a microscope, an external set stepless zoom case is arranged at the side of a manual zoom regulating shaft of the microscope. A stepless zoom drive mechanism, a caging device and a control circuit are arranged in the zoom case, the stepless zoom drive mechanism comprises a micromotor, a two-stage reducer composed of a gear pair and a worm gear pair, and the worm-wheel shaft of the reducer is connected with the manual zoom regulating shaft of the microscope through a shaft coupler. The caging device mainly comprises a pair of caging collars installed on the worm-wheel shaft, colliding blocks are respectively arranged on the two caging collars, and two caging inching switches are arranged on the corresponding position. The ordinary microscope is additionally provided with the external set stepless zoom case, not only the high-performance microscope with the electric control stepless zoom function is produced, but also the ordinary microscope can be reconstructed at low cost into the microscope with the electric control stepless zoom function.
Description
Affiliated technical field
The utility model relates to the microscope in the medicine equipment, refers to that specifically microscopical change doubly installs.
Background technology
Microscope in use needs to regulate its enlargement factor.Because the restriction of microscope light path and physical construction, generally all employing simply manually becomes times structure, promptly becomes a times knob by adjusted and rotates change times regulating shaft, thereby realize the change of its enlargement factor.Manually become doubly and need operate with hand, obviously convenient inadequately concerning the very busy medical worker of both hands like this.At present, have only the minority ophthalmic operating microscope to adopt built-in stepless change times structure, but the structure more complicated of the built-in stepless change power microscope of this specialty, price is very expensive, and can not transform simple microscope.
Summary of the invention
The purpose of this utility model is to propose the automatically controlled stepless change of a kind of microscope external and doubly installs, by on simple microscope, installing light, small and exquisite a, high-performance, times box of the stepless change of external cheaply additional, realize the stepless anamorphosis function of simple microscope, to overcome the deficiencies in the prior art.
The automatically controlled stepless change of a kind of microscope external of the present utility model is doubly installed, comprise a simple microscope, be provided with the stepless change of an external times box in this microscopical manual change times regulating shaft is other, be provided with stepless change times gear train, stop means and control circuit in this change times box; Described stepless change times gear train comprises that a micromotor, pays the two stage reducer of forming by one group of gear pair and one group of worm and gear, and the worm-wheel shaft of described speed reduction unit links to each other with a microscopical manual change times regulating shaft by a shaft coupling.During operation, the operator controls the running of foot controller control micromotor, and the transmission that motor is paid by gear pair, worm and gear makes worm-wheel shaft and becomes a times regulating shaft rotation by its drive is manual, thereby realizes the automatic change of microscope operation doubly.
Because microscopical change doubly can only be carried out within the specific limits, can only carry out within the specific limits so automatically controlled stepless change is doubly operated also.For this reason, limit becoming the scope of doubly regulating by one group of stop means.Described stop means mainly comprises a pair of spacing collar that is loaded on the worm-wheel shaft, this two spacing collars position on worm-wheel shaft can be regulated by holding screw, on two spacing collars, be respectively equipped with collision block, be provided with two position limited inching switches in the correspondence position that becomes times box in addition, the position of this two microswitch is in respectively on the movement locus of two collision blocks, and is determined by the extreme position of worm-wheel shaft.When rotating to extreme position, control circuit shuts down motor immediately, and reports to the police according to the state of position limited inching switch when worm-wheel shaft (times regulating shaft is coaxial with becoming).
Advantage of the present utility model is by install the stepless change of external times box additional on simple microscope, high performance microscope can not only be produced, and microscope can be at low cost simple microscope be transformed into automatically controlled stepless anamorphosis function with automatically controlled stepless anamorphosis function.
Description of drawings
Fig. 1 is the structural representation of the automatically controlled stepless change times box of external of the present utility model;
Fig. 2 is the vertical view of Fig. 2;
Fig. 3 is an installation site of the present utility model synoptic diagram.
Among the figure: 1 microscope body, 2 manually become times regulating shaft, and 2a manually becomes times adjusting knob, and 3 become times box, the 3a base plate, the 3b lid, 4 micromotors, 51,52 gear pairs, 61,62 worm and gears are paid, 63 worm-wheel shafts, 7 shaft joints, 81,82 spacing collars, 91,92 collision blocks.10 flanges, S1, S2 position limited inching switch, 11 control circuit boards.
Embodiment
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing.
External of the present utility model becomes manual change times regulating shaft 2 sides that times box 3 is located at microscope body 1, as shown in Figure 3.
By Fig. 1, Fig. 2, becoming times box 3 is made up of base plate 3a and lid 3b, base plate 3a is fixed on micromachine 4 on the other microscope body 1 of manual change times regulating shaft 2, stepless change times gear train by joint flange 10 and is installed on the base plate 3a with, stop means and control circuit board 11, and lid 3b covers on the base plate 3a.
Described stepless change times gear train comprises that a micromotor 4, pays 61,62 two stage reducers of forming by 51,52 and one groups of worms and wormwheels of one group of gear pair, and the worm-wheel shaft 63 of this stepless change times gear train links to each other with manual change times regulating shaft 2 by shaft joint 7.
Described limit control mainly comprises two spacing collars 81,82 that are loaded on the worm-wheel shaft 63, this two spacing collars position on worm-wheel shaft can be regulated by holding screw, on two spacing collars, be respectively equipped with collision block 91,92, be provided with two microswitch S1, S2 in the correspondence position that becomes times box plate in addition, the position of this two microswitch is in respectively on the movement locus of two spacing collars 81,82, and is determined by the extreme position of worm-wheel shaft 63.
Claims (2)
1. the automatically controlled stepless change of microscope external is doubly installed, comprise a simple microscope, it is characterized in that: in the other stepless change of an external times box that is provided with of the manual change times regulating shaft of simple microscope, be provided with stepless change times gear train, stop means and control circuit in this change times box, described stepless change times gear train comprises that a micromotor, pays the two stage reducer of forming by one group of gear pair and one group of worm and gear, and the worm-wheel shaft of described speed reduction unit links to each other with a microscopical manual change times regulating shaft by a shaft coupling.
