Abstract
The invention discloses a lens stand. The lens stand comprises a pedestal and a barrel, wherein the barrel is extended from the pedestal to the axial direction of the barrel. A first cavity for holding an image sensor is formed in the pedestal, the barrel encircles a second cavity for holding a lens barrel assembled with an optical lens, and the lens barrel is screwed with the barrel. A circular groove is formed inside the end of the pedestal close to the barrel, and the inner surface of the circular groove is a smooth surface. The inside diameter of the circular groove is greater than or equal to that of the barrel. A plurality of through grooves are formed in the axial direction of the barrel, and the through grooves are extended to the tail end of the barrel from the intersected position of the barrel and the pedestal. When the lens barrel and the barrel are blocked by threads or the torsion of the lens barrel relative to the barrel is over high, the screwed position between the lens barrel and the barrel can be conveniently adjusted, so that the lens barrel is stably screwed with the barrel. The invention also provides a lens module with the lens stand.

Embodiment
Below in conjunction with accompanying drawing and multiple embodiment, microscope base of the present invention and the camera lens module with this microscope base are described in further detail.
First embodiment
See also Fig. 1 to Fig. 3, its a kind of microscope base 10 provided for the first embodiment.This microscope base 10 comprises integrated pedestal 11 and cylinder portion 13, and described cylinder portion 13 extends from pedestal 11 along the axis in cylinder portion 13.Described pedestal 11 encloses the first cavity 111 formed for accommodating image sensor, described cylinder portion 13 surrounds second cavity 131 is assembled with optical lens lens barrel 40 (referring to Fig. 6) in order to collecting, and described second cavity 131 and the first cavity 111 are interconnected.
In present embodiment, described pedestal 11 is cube-shaped framework, and described cylinder portion 13 is in hollow cylindrical.The tip inside of described pedestal 11 near a portion 13 is formed with a circular groove 113, and described circular groove 113 is for positioning lens barrel 40.Concrete, the inside surface of described circular groove 113 is smooth surface, the internal diameter of described circular groove 113 slightly larger than or equal the internal diameter in described cylinder portion 13.
The external diameter in described cylinder portion 13 is less than or equal to the length of side of pedestal 11.The inside surface of described second cavity 131 forms multiple internal thread (not shown).Described cylinder portion 13 is axially formed with multiple groove 133 along it, and the bearing of trend of described groove 133 and the central shaft in described cylinder portion 13 are parallel to each other, and described groove 133 extends to the tail end in a portion 13 from described cylinder portion 13 and the intersection of pedestal 11.In present embodiment, the quantity of described groove 133 is four.Described cylinder portion 13 is divided into the curved portions at multiple interval by described groove 133, when described lens barrel 40 is housed in described second cavity 131, if there is screw thread stuck phenomenon in lens barrel 40 and described cylinder portion 13, then can make the relative lens barrel 40 in described cylinder portion 13 that radial elastic deformation occur by external force, thus the mutual alignment in lens barrel 40 and described cylinder portion 13 can be adjusted relatively easily, make lens barrel 40 and described cylinder portion 13 return to the state that is normally spirally connected, avoid damaging the screw thread on cylinder portion 13 or lens barrel 40.In present embodiment, the material in described cylinder portion 13 is plastic cement, and its elasticity coefficient is less than or equal to the elasticity coefficient of lens barrel 40.
Refer to Fig. 4, the present invention also provides a kind of camera lens module 100, and described camera lens module 100 comprises described lens barrel 40 and above-mentioned microscope base 10, described lens barrel 40 and described microscope base 10 threaded engagement.When assembling in described lens barrel 40 to described microscope base 10, the lens barrel 40 that optical lens is housed is put into described circular groove 113 (referring to Fig. 2) from described first cavity 111, after the sidewall of lens barrel 40 and the sidewall of circular groove 113 fit tightly, can determine that lens barrel 40 is steadily placed.Then, lens barrel 40 rotation is screwed into described cylinder portion 13.Now, if the threaded engagement precision in the screw thread of lens barrel 40 or cylinder portion 13 is not high, cause lens barrel 40 and cylinder portion 13 that screw thread stuck phenomenon occurs, or when the external diameter of lens barrel 40 is less times greater than the internal diameter in described cylinder portion 13, torsion can increase, and now makes described cylinder portion 13 that elastic deformation occur by external force, thus can adjust the screw position between lens barrel 40 and cylinder portion 13 easily, lens barrel 40 and cylinder portion 13 are steadily spirally connected, easy for installation.
Second embodiment
Refer to Fig. 5, the microscope base 20 that second embodiment provides is roughly the same with the microscope base 10 that the first embodiment provides, and its difference is, described microscope base 20 also comprises a urceolus 15, described urceolus 15 around described cylinder portion 13a, and is arranged with described cylinder portion 13a concentric.The diameter of described urceolus 15 is greater than the diameter of described cylinder portion 13a, makes to be formed with a gap 17 between described urceolus 15 and described cylinder portion 13a.In present embodiment, described urceolus 15 is the ring-type closed.Described urceolus 15, for when radial elastic deformation occurs cylinder portion 13a, stops that it continues to increase deformation, cannot recover to avoid a portion 13a because deformation is excessive.Be appreciated that, after lens barrel 40 is assembled to this microscope base 20, described urceolus 15 can also work the effect of being in the light, prevent parasitic light from entering optical mirror slip in lens barrel 40.
3rd embodiment
Refer to Fig. 6, the microscope base 30 that 3rd embodiment provides is roughly the same with the microscope base 10 that the first embodiment provides, its difference is, microscope base 30 also comprise multiple be in same circumference and separate arc columnar part 151a, described multiple arc columnar part 151a correspondence is arranged on described groove 133 side, to hide described groove 133a.In present embodiment, the quantity of described arc columnar part 151a is four, and each described arc columnar part 151a hides described groove 133 completely.The end of described arc columnar part 151a is formed with a grab 19, and described grab 19 extends to the position flushed with cylinder portion 13b inside surface along lens barrel 40 radial direction, and when 13b deformation in cylinder portion is excessive, grab 19 and cylinder portion 13b hook together.Thus, the microscope base 40 of present embodiment can not only stop that portion's 13b deformation is excessive, can also be in the light to optical lens.Certainly, the quantity of described arc columnar part 151a is not limited only to four, can increase according to specific needs or reduce its quantity.
Microscope base of the present invention is offered a circular groove 113 on its base and is arranged groove 133 in its portion, can adjust the position of the lens barrel 40 that optical lens is housed in advance, makes it be spirally connected with cylinder portion 13 more reposefully.When lens barrel 40 is not high with the threaded engagement precision in cylinder portion 13, when causing lens barrel 40 and cylinder portion 13 that stuck phenomenon occurs, or when the external diameter of lens barrel 40 is less times greater than the internal diameter in described cylinder portion 13, torsion can increase, make described cylinder portion 13 that elastic deformation occur by external force, thus the position that is spirally connected that can adjust easily between lens barrel 40 and cylinder portion 13, lens barrel 40 and cylinder portion 13 are steadily spirally connected, easy for installation.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
