Description
Technical field
The utility model relates to a kind of lens barrel and microscope base, second annular conical surface that relates in particular to a kind of first annular conical surface of lens barrel and microscope base reaches and prevents that bits, some glue are convenient, and uses corresponding second annular conical surface of first annular conical surface to make the lens barrel and the microscope base of the effect of central shaft and optical axis coincidence.
Background technology
Lens barrel and the microscope base that can see on the market at present, as shown in Figure 1, it comprises a lens barrel 10 and microscope base 11, be formed with a hollow channel 12 in the lens barrel 10, be embedded with a lens combination 13 in this hollow channel 12, the optical axis a of lens combination 13 overlaps with the central shaft b of hollow channel 12, but the light signal scioptics group 13 of object and converging on the image sensor 14, and be provided with internal thread in the hollow channel 12 of lens barrel 10, and in microscope base 11 the same hollow channel 121 that forms, its outer surface is provided with external thread, and be meshed with the internal thread of lens barrel 10, though small trifling the falling on the image sensor 14 when using said structure can prevent lens barrel 10 with microscope base 11 combinations is shaped and influence image, using later, its problem is:
One, because lens barrel 10 is directly to mesh with single screw thread with microscope base 11, so when assembling lens barrel 10 and microscope base 11, easily because of rocking or threaded engagement is incorrect to be made optical axis a overlap with central shaft b to depart from, and the light signal can't be delivered on the image sensor 14 accurately, make image fog or halation occurs.
They are two years old, when lens barrel 10 and microscope base 11 is under the situation about directly meshing with single screw thread, allow the lens barrel 10 and the engagement place of microscope base 11 produce the gap during long-term the use easily, and in a single day the gap produces and promptly can enlarge day by day, optical axis a and central shaft b then can produce and depart from like this, allow object the light signal can't as the expection be sent on the image sensor 14, so effect is undesirable.
The utility model content
The technical problems to be solved in the utility model provides a kind of bits, some glue convenience of preventing, and use the second corresponding annular conical surface of first annular conical surface to make central shaft and optical axis coincidence, it comprises members such as a lens barrel, a microscope base, a lens combination and a group image sensor and forms, and the purpose of this utility model is:
The modern is more and more higher for the requirement of the sharpness of image, the sharpness of image then is that the light signal of object converges and is delivered to then on the image sensor through lens combination, and the central shaft that must make optical axis and lens barrel, microscope base in the middle of this overlap just can reach the best become the shadow effect, so in view of this, lens barrel of the utility model and microscope base improvement, as shown in Figure 2, it comprises that lens barrel, microscope base and lens combination form, and entirety of lens package is located among the lens barrel, lens barrel is relative with microscope base, make up to screw togather the mode that locks, so optical axis promptly can overlap with central shaft.
For solving the problems of the technologies described above, first annular conical surface that the utility model forms on lens barrel and relative microscope base form second annular conical surface, and allow first annular conical surface and the second annular conical surface tabling, can use the corresponding conical surface to make the central shaft location of lens barrel and microscope base firm, and optical axis and central shaft can not depart from yet under long-term use, the light signal of object can be converged accurately, and be sent to image sensor, and lens barrel can be lowered and microscope base rocks, in this lens barrel of the present utility model as can be known and the microscope base design is very firm and stability is splendid.
For solving the problems of the technologies described above, the utility model is provided with locking part and is meshed with the corresponding portion of microscope base in the lens barrel inboard, and locking part and outside corresponding portion reaches by this and prevents that bits, some glue are convenient.
The utility model prevents bits, some glue conveniently owing to reaching, and uses corresponding second annular conical surface of first annular conical surface to make the effect of central shaft and optical axis coincidence.Has novelty and creativeness.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model comprises members such as a lens barrel 20, a microscope base 30, a lens combination 40 and a group image sensor 50 and forms, as shown in Figure 2, and wherein:
Lens barrel 20 is the interior hollow cylinder that accommodation space 21 is arranged, and 211 inboards of the flange below lens barrel 20 are provided with locking part 22, and the outside of flange 211 is provided with first annular conical surface 23 below lens barrel 20;
Microscope base 30 is the interior hollow base frame that accommodation space 31 is arranged, and is provided with corresponding portion 32 on the flange 321 in microscope base 30 outsides, and is provided with depressed part 331 on microscope base 30 flanges 321 bottoms, and this depressed part 331 is provided with second annular conical surface 33;
Lens combination 40, group is located in the accommodation space 21 of lens barrel 20;
Image sensor 50, group is located in the accommodation space 31 of microscope base 30.
Embodiment 1
As shown in Figure 2, lens combination 40 is installed in the lens barrel 20, and the locking part 22 of lens barrel 20 is an internal thread, be positioned on the flange of accommodation space 21, be provided with first annular conical surface 23 that forms the inclined-plane in lens barrel 20 outsides, then the corresponding portion 32 of microscope base 30 is an external thread, be positioned on the flange in microscope base 30 outsides, and with the engagement of the internal thread of lens barrel 20, locking part 22 is outside corresponding portion 32, and microscope base 30 is provided with a depressed part 331, and be provided with first annular conical surface, 23 corresponding second annular conical surfaces 33 with lens barrel 20 outsides in depressed part 331 wall sides, use first annular conical surface 23 and second annular conical surface 33 that lens barrel 20 is overlapped with the optical axis a of lens combination 40 with the central shaft b of microscope base 30, so earlier with lens barrel 20 and microscope base 30 relative after, in locking part 22 and corresponding portion 32 engagements, first annular conical surface 23 and second annular conical surface 33 are chimeric too, again glue is put at last in lens barrel 20 first annular conical surfaces 23 and microscope base 30 second annular conical surfaces 33 joints, fix by the gummed mode, and microscope base 30 height can surpass the bottom of lens barrel 20, make combined and instant between the two; Reach by this light signal can accurately be delivered on the shadow sensor 50, and optical axis a and central shaft b yet can not depart from and lower lens barrel 20 and rock with microscope base 30 under long-term use, more can be meshed by the corresponding portion of lens barrel locking part with microscope base, locking part and outside corresponding portion reaches and prevents that bits, some glue from acting on easily.
