Description
Technical Field
The utility model relates to a teaching facility, concretely relates to optical system teaching stand.
Background
The assembly and debugging of the camera lens in the optical system are very complex, and the assembly and debugging involve the adjustment of the interval of each lens, the position of a diaphragm, the total optical length and the like in the lens, which directly affect the imaging quality of the lens, and a clear image is necessarily the result of continuous analysis and debugging.
In the teaching process of the optical system, the imaging principle and the debugging process need to be displayed to students by adjusting the intervals of all lenses, the positions of diaphragms, the total optical length and the like, but the existing teaching display equipment is complex to operate, wastes time and labor.
Disclosure of Invention
The utility model aims at providing a compact structure, use reliable optical system teaching stand, solve the problem that the operation is complicated that current teaching display device exists, labour saving and time saving.
The technical scheme of the utility model is that:
the utility model provides an optical system teaching stand, includes supporting platform, is located each lens, the diaphragm of supporting platform top and has imaging sensor's circuit board, and the coincidence of each lens, diaphragm and imaging sensor's central line, the signal output part of circuit board links to each other with the computer, and its technical essential is: the periphery of each lens, diaphragm and circuit board is equipped with the carriage respectively and with carriage complex side cap, the carriage is down along being fixed with the silk braid and left and right support wheelset, the silk braid is located between left and right support wheelset on the horizontal direction, and the silk braid on each carriage is staggered arrangement on the horizontal direction, supporting platform comprises left and right support rail, the preceding, the back supporting shoe of connecting in left and right support rail preceding, rear end that are parallel to each other, and left and right support rail upper surface is equipped with the logical long recess that corresponds with left and right support wheelset, be equipped with the lead screw with each silk braid one-to-one between preceding, the back supporting shoe, the one end that the circuit board was kept away from to the lead screw is fixed with the knob.
The optical system teaching display stand is characterized in that the inner peripheral wall of the bearing frame is provided with a compensating washer for fixing lenses with different outer diameters.
In the optical system teaching display stand, the length of the thread sleeve is greater than the thickness of the bearing frame, so that the driving stability is improved.
The utility model has the advantages that:
1. each lens of cooperation drive through lead screw, silk cover, diaphragm and circuit board on the optical axis position change to reach the interval of adjusting each lens, the position and the optics total length of diaphragm, make the student more clearly and definitely the formation of image principle, how to debug the formation of image effect, it is very convenient when utilizing the knob to adjust, labour saving and time saving has solved the problem that the operation is complicated that current teaching display device exists.
2. The assembling mode of the bearing frame and the side cover is more convenient to replace a very-type lens, diaphragms with different apertures and circuit boards of different types, and the bearing frame and the side cover are flexible to use and simple to operate.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a side view of the present invention.
In the figure: 1. the device comprises a support rail, 2 support wheel sets, 3 bearing frames, 4 side covers, 5 thread sleeves, 6 lead screws, 7 support blocks, 8 knobs, 9 diaphragms, 10 lenses, 11 gaskets, 12 circuit boards, 13 imaging sensors and 14 computers.
Detailed Description
As shown in fig. 1 and fig. 2, the optical system teaching display stand comprises a supporting platform, three lenses 10 positioned above the supporting platform, a diaphragm 9 and a circuit board 12 with an imaging sensor 13, wherein the center lines of the three lenses 10, the diaphragm 9 and the imaging sensor 13 are coincident, and the signal output end of the circuit board 12 is connected with a computer 14.
The peripheries of the three lenses 10, the diaphragm 9 and the circuit board 12 are respectively provided with a bearing frame 3 and a side cover 4 matched with the bearing frame 3, and the lower edge of the bearing frame 3 is fixed with a screw sleeve 5 and a left and a right supporting wheel sets 2. The thread sleeves 5 are horizontally positioned between the left and right supporting wheel sets 2, and the thread sleeves 5 on the bearing frames 3 are horizontally arranged in a staggered manner. The supporting platform consists of a left supporting rail 1 and a right supporting rail 1 which are parallel to each other, and a front supporting block 7 and a rear supporting block 7 which are connected to the front end and the rear end of the left supporting rail 1 and the rear end of the right supporting rail 1. The upper surfaces of the left and right supporting rails 1 are provided with through long grooves corresponding to the left and right supporting wheel sets 2. And lead screws 6 which are in one-to-one correspondence with the screw sleeves 5 are arranged between the front supporting block 7 and the rear supporting block 7, and a knob 8 is fixed at one end, far away from the circuit board 12, of each lead screw 6.
In this embodiment, in order to fix lenses with different outer diameters, the inner peripheral wall of the carrying frame 3 outside the two lenses 10 close to the object side is provided with a compensation washer 11. The length of the thread sleeve 5 is larger than the thickness of the bearing frame 3 so as to improve the driving stability.
When the adjustable lens is used, the screw rod 6 is rotated through the knob 8, so that the lens 10, the diaphragm 9 and the circuit board 12 are driven to displace, the mutual distance is changed, and the purpose of adjustment is achieved. The imaging sensor 13 on the circuit board 12 converts the optical signal into an electrical signal and transmits the electrical signal to the computer 14, and imaging on the display screen of the computer 14 is convenient for a student to observe imaging effect.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
