Detailed description of the invention
The embodiment of barrel assembly described in the utility model is described below with reference to the accompanying drawings.This area
Those of ordinary skill will be consequently realised that, in the case of without departing from spirit and scope of the present utility model, and can
By with various different in the way of or a combination thereof described embodiment is modified.Therefore, accompanying drawing and retouching
State the most illustrative rather than for limiting scope of the claims.Additionally, at this
In description, accompanying drawing draws not in scale, and identical reference represents identical part.
Provide a kind of barrel assembly in the present embodiment, barrel assembly as shown in Figure 1, including: lens barrel
1, this lens barrel 1 is the structure of cylindric upper opening, and the bottom of lens barrel 1 is provided with the unthreaded hole of preliminary dimension,
This unthreaded hole penetrates the core of the lower surface of the closing of this lens barrel 1 and is formed, and unthreaded hole is placed in for exposure
First eyeglass 2 of lower section;Eyeglass, eyeglass can be one or more, and eyeglass is stacked on towards unthreaded hole direction
In lens barrel so that the center superposition of eyeglass;In annular gap between lens barrel 1 and eyeglass, O is installed,
O is for adjusting the size of unthreaded hole, and O is for adjusting the amount of interference between eyeglass and lens barrel 1.
By said structure, according to various sizes of eyeglass, as long as changing different O, can complete
The adjustment of the amount of interference between the adjustment of unthreaded hole, and eyeglass and lens barrel 1 so that the optical center energy of eyeglass
Reach and the center superposition of lens barrel 1, and then make lens combination reach optimum solution image force state.Solve basis
It is corresponding that different lens design must produce new lens barrel mould, and carries out according to actual size after lens barrel molding
Die correction so that the problem that exploitation schedule cannot shorten.
In one alternate embodiment, as it is shown in figure 1, this eyeglass includes the first eyeglass 2, this first eyeglass
2 foots being positioned at lens barrel 1;Be provided with the first O 3 in the lower section of this first eyeglass 2, this is first years old
The lower surface laminating of the upper surface of O 3 and this first eyeglass 2, the excircle of this first O 3
The inner peripheral surface laminating of face and unthreaded hole, this first O 3 is for adjusting the size of this unthreaded hole, by more
Change the first O 3, the size of lens barrel unthreaded hole can be adjusted as required.
As it is shown in figure 1, in one alternate embodiment, in the first eyeglass 2 and the annular gap of lens barrel 1
Inside being provided with the second O 4, this second O 4 is for adjusting the dry of the first eyeglass 2 and lens barrel 1
The amount of relating to, according to various sizes of first eyeglass 2, by changing the second O 4, i.e. adjustable the first mirror
The center of sheet 2 and stacking eyeglass above it and the center superposition of lens barrel 1.
As in figure 2 it is shown, in one alternate embodiment, this eyeglass includes the second eyeglass 7, this second eyeglass
7 tops being positioned at other eyeglasses.The 3rd O 5 He it is provided with between this second eyeglass 7 and lens barrel 1
4th O 6, at the inner surface of lens barrel 1, has and lays the 3rd O 5 and the 4th O 6
Shoulder, the 3rd O 5 is placed in the upper surface of shoulder, and the 4th O 6 is placed in the 3rd O 5
Upper surface, the second eyeglass 7 be positioned at below the second eyeglass 7 and the eyeglass adjacent with the second eyeglass 7
Between be provided with spacer ring 8, the inner peripheral surface patch of the outer circumference surface of this spacer ring 8 and the 3rd O 5
Closing, this spacer ring 8 is used for adjusting mirror spacing;3rd O 5, the 4th O 6 are for adjustment the
Amount of interference between two eyeglasses 7 and lens barrel 1.By changing spacer ring 8, in that context it may be convenient to adjust mirror spacing,
According to various sizes of second eyeglass 7, by changing the 3rd O the 5, the 4th O 6, can adjust
Whole second eyeglass 7 and the amount of interference of lens barrel 1 so that the center of the second eyeglass 7 is heavy with the center of lens barrel 1
Close.
As in figure 2 it is shown, in one alternate embodiment, between the first eyeglass 2 and the second eyeglass 7,
It is stacked with eyeglass.The upper surface of each eyeglass and the position of engagement sides in the eyeglass of stacking have annular
Projection, stacking eyeglass in the lower surface of each eyeglass and the position of engagement sides there is loop concave,
The eyeglass of stacking is mutually fastened by this annular projection and this loop concave, for guaranteeing stablizing of optical axis.
In one alternate embodiment, annular projection and the loop concave of eyeglass can be multiple, i.e.
Outer annular projection and the radially inner side of loop concave, can have annular projection and loop concave the most again,
Make optical axis more stable.And, annular projection can have fixed block radially along horizontal direction,
The radial direction of loop concave, with on the fixed block of annular projection position one to one, can have fixing groove,
When making to fasten, fixed block and fixing groove grafting, limit the circular-rotation of eyeglass further.
The material of lens barrel can be various, in one alternate embodiment, uses aluminum lens barrel, it is possible to
Lens barrel is made to have advantage lightweight, that intensity is high.
The mutual snap-fit design of high-pixel camera head mirror sheet is present to ensure that optical axis stable, first piece, last
Piece eyeglass and mechanism member are main and lens barrel interference parts.Design general aluminum lens barrel difference of arranging in pairs or groups
Rubber o-ring size guarantee lens barrel light hole size (the first O) and component interference amount (second and third,
Four O), as in figure 2 it is shown, this general lens barrel only needs replacement o circle can meet different high pixel
Photographic head demand.
In sum, by barrel assembly of the present utility model, it is achieved that techniques below effect:
1. use the eyeglass with annular projection and loop concave mutually to fasten so that lens set is more firm,
And then guarantee optical axis stable;
2. can quickly adjust the size of unthreaded hole by replacement o circle, and adjust the dry of eyeglass and lens barrel
The amount of relating to, and then accelerate the judgement speed to lens monomer optical characteristics, shorten the construction cycle.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, right
For those skilled in the art, this utility model can have various modifications and variations.All in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection domain of the present utility model.
