The technical problems to be solved in the utility model is the problem that exists at above-mentioned micro objective objective apparatus, a kind of novel micro objective device is provided, make microscopical simple in structure, easy to assembly, and reduced the difficulty of processing of critical component and assembled difficulty, improve product percent of pass, further reduced microscopical cost.
The technical solution of the utility model is: novel micro objective device, and it is located at eyepiece below, and described novel micro objective device is made up of the jacket tube that vertically is provided with perforation, the last cup being located at rotatable urceolus in the overcoat and being located at the overcoat top; Its sleeve side wall has a window, is provided with inner core in the urceolus, is provided with object lens moving up and down in the inner core; It is characterized in that: the inner core in the described urceolus is provided with fluting, and described object lens are arranged in the objective tube.
Fluting on the described inner core is axial along inner core.
Described have two at least along the axial fluting of inner core.
Described overcoat is provided with window, and the corresponding position of window of described urceolus is provided with projection.
The arranged outside of described objective tube has and the corresponding protruding button of fluting on the inner core, and protruding button protrudes from the lateral surface of inner core.
The inwall of described urceolus be provided with objective tube on stretch out the helical guideway groove that the protruding button of slotting on the inner core matches.
Described inner core upper end is provided with the flange platform, is provided with projection above the flange platform, and the relevant position of projection and last cup is chimeric fixing.
Compare with prior art, the beneficial effects of the utility model are: this novel objective apparatus has been saved the structure that guide bar has been simplified inner core, object lens are directly installed on the objective tube, reduced the difficulty of processing of each parts, reduced the assembling difficulty of micro objective device, improved yield rate, last cup and overcoat socket, moving up and down of rotating band animal lens barrel by urceolus, thus object lens are moved up and down.So just can regulate the focal length and the microscopical enlargement ratio of object lens.The processing assembling of the utility model product is easier, and cost is lower, and product is more durable, and precision is higher, better quality.
