Description
Technical field
The utility model relates to the simple microscope that a kind of student experimenting is used.
Background technology
At present, the biology laboratory of school is difficult to offer the operation that experimentizes of everyone microscope of student.Microscopical shortage has restricted carrying out of student's Bioexperiment.After more existing schools carry out student experiment in group or lecture experiment, though the student is gone up on the surface experimental result is answered fluently, in fact the student obviously is to lack practice to standardization, the dexterity of whole experimental implementation.
If thereby microscopical one-tenth instinct reduces and to make and can both afford an one's own microscope in each student's hand, the study of student's microscope short-term will become long-term autonomous Inquiry Learning so.To Students'learning is a lot of benefits.
The utility model content
The purpose of the utility model provides a kind of simple microscope with low cost.
For achieving the above object, the utility model is taked following technical scheme:
Simple microscope comprises microscope base, upright arm, transverse arm, fixed lens barrel, draw tube, focusing wheel and objective table; Said microscope base is processed by plank; Said upright arm and transverse arm are processed by pvc pipe; Said fixed lens barrel is the PVC three-way piece that is provided with preformed groove; Said draw tube is a pvc pipe; Said focusing wheel is the toy wheel; Said objective table is made up of support arm that links together and transparent plate body; Upright arm is vertically fixed on the microscope base; One end of transverse arm and upright arm be linked together, the central connector of the other end of transverse arm and fixed lens barrel be linked together; The preformed groove of fixed lens barrel is positioned on its one of them straight-through connector, and towards central connector; The straight-through connector that is provided with preformed groove of fixed lens barrel up, the non-straight-through connector that is provided with preformed groove is down; Draw tube is inserted in the straight-through connector that is provided with preformed groove of fixed lens barrel, but and the relative fixed lens barrel move up and down; Outer surface at draw tube is fixed with a tooth bar parallel with the draw tube axis direction, and tooth bar is among the preformed groove of fixed lens barrel; Be connected with wheel shaft on the focusing wheel, wheel shaft is horizontally through the central connector of fixed lens barrel; Gear is housed on wheel shaft, and gear mesh is answered tooth bar and is carried out transmission; In fixed lens barrel non-is provided with the straight-through connector of preformed groove, object lens are installed; Eyepiece is installed in draw tube.
During use, rotate the focusing wheel, but then draw tube relative fixed lens barrel moves upward or moves downward and focus.Because the most materials of the utility model all are to process with cheap material, so the manufacturing cost of this machine is very low.Under the prerequisite that satisfies student's request for utilization, greatly reduce student's acquisition cost.
As improvement, also a lighting device can be set below objective table, be used for initiatively providing to observe using up.
In addition, can be provided with the camera web member, be used to connect computer camera at the end that is used to observe of draw tube.So the sight in the microscope can show through computer display screen, and capture and record a video, improve the Students'learning quality greatly through computer software.
It is easy, simple and practical, cheap that the utility model is made, and can improve students'interest in learning and results of learning greatly as the teaching accessory.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further.
As shown in Figure 1, the present embodiment simple microscope comprises: microscope base 1, upright arm 2, transverse arm 3, fixed lens barrel 4, draw tube 5, focusing wheel 6 and objective table 7.
Microscope base 1 is processed by plank.Upright arm 2 and transverse arm 3 are processed by pvc pipe.Fixed lens barrel 4 is the PVC three-way pieces that are provided with preformed groove 44.Draw tube 5 is pvc pipes.Focusing wheel 5 is toy wheels.Objective table 7 is made up of support arm that links together 71 and transparent plate body 72.
Upright arm 2 is vertically fixed on the microscope base 1.One end of transverse arm 3 and upright arm 2 be linked together, the central connector of the other end of transverse arm 3 and fixed lens barrel 4 43 be linked together; The preformed groove 44 of fixed lens barrel 4 is positioned on its first straight-through connector 41, and towards central connector 43; First of fixed lens barrel 4 leads directly to connector 41 up, and the second straight-through connector 42 down; Draw tube 5 is inserted in the first straight-through connector 41 of fixed lens barrel 4, but and relative fixed lens barrel 4 move up and down; Outer surface at draw tube 5 is fixed with a tooth bar 8 parallel with draw tube 5 axis directions, and tooth bar 8 is among the preformed groove 44 of fixed lens barrel 4.Be connected with wheel shaft 9 on the focusing wheel 6, wheel shaft 9 is horizontally through the central connector 43 of fixed lens barrel 4, and gear 10 is housed on wheel shaft 9, gear 10 corresponding tooth bars 8 and carry out transmission.In the second straight-through connector 42 of fixed lens barrel 4, object lens 11 are installed, eyepiece 12 is installed in draw tube 5.Rotate focusing wheel 6, gear 10 cooperates transmission with tooth bar 8, and draw tube 5 relative fixed lens barrels 4 move upward accordingly and move downward, thereby can change the distance between object lens 11 and the eyepiece 12, realize focusing.
In the present embodiment, below objective table, be provided with a lighting device that constitutes by box body 13, dry cell 14, lamp pearl 15 and switch 16, be used for initiatively providing to observe using up.
