At first, see also Fig. 1, disclose the configuration cut-away view of the utility model the first embodiment, a kind of CCD image-taking device that the utility model provides is described, comprise a sampling image lens 10, a stretching tube 20, a camera lens stack shell 30 and a zoom lens 40, wherein:

This sampling image lens 10 is commercial product, in be loaded with a charge coupled cell 11 (CCD), and these sampling image lens 10 1 ends have the charge coupled cell 11 capture hole 12 that external capture is used are provided.In addition, this sampling image lens 10 also has a cohesive end 13 can supply fixedly sampling image lens 10, and perhaps, this cohesive end 13 also can provide the linking driving element to move to drive sampling image lens 10.

This stretching tube 20 is the socket shape body of both-end opening, is formed with energy and the capture hole 12 fixing spiro union portions 21 of linking on one end outer wall, makes stretching tube 20 to be fixed into one with sampling image lens 10; The other end of stretching tube 20 is made T shape socket 22 forms of expanding, and is formed with a groove 23 in stretching tube 20, and these groove 23 energy and capture hole 12 are connected.

The both-end of this camera lens stack shell 30 externally is open shape, and be to make external diameter to be slightly less than the straight tube body of a groove 23, the outer wall energy of camera lens stack shell 30 is slidedly arranged in above-mentioned cylinder groove 23, and be formed with a containing hole 31 in this camera lens stack shell 30, be formed with a lock-joining part 32 on the hole wall in these containing hole 31 contiguous capture holes 12, utilize this lock-joining part 32 described zoom lens 40 that locks, and then make camera lens stack shell 30 and zoom lens 40 be fixed into one.

This zoom lens 40 is socket shape body, form by establishing lens 50 in a lens barrel 41, a stiff end 43 and an exposed junction 44 that this lens barrel 41 has a mirror hole 42 and is seated these mirror hole 42 bilaterals, this stiff end 43 provides the lock-joining part 32 of above-mentioned camera lens stack shell 30 fixing, expose the bottom that this exposed junction 44 extends to camera lens stack shell 30, and this exposed junction 44 is formed with mirror groove 45 and fixes lens 50.When wish application the utility model increased the enlargement ratio of sampling image lens 10 picked-up imagings, these lens 50 can select convex lens to be implemented.

According to above-mentioned configuration, these lens 50 can provide charge coupled cell 11 sequentially via capture hole 12, mirror hole 42, to have an X-rayed the external world 60 to the CCD image-taking device.

Then, see also 2, disclose the key diagram of device shown in Figure 1 before stretching, the outer wall that this stretching tube 30 is described forms a fixed part 33, utilize this fixed part 33 and the CCD image-taking device that the utility model provides is fixed in a stiff end 70, this stiff end 70 is provided by a detection machine, and the equipment that perhaps by other demands, mounts the CCD image-taking device is provided.Then, when between stretching tube 20 and camera lens stack shell 30 in the situation that do not have to move relative to stretching, charge coupled cell 11 can be used lens 50 as visual focus P and tested object 80 captures one of in 60 to external world, wherein, is to use distance between capture hole 12 and visual focus P as focal distance f 1.In particular, cylinder groove 23 in stretching tube 20 has one and is beneficial to and adjusts that camera lens stack shell 30 approaches relatively or away from the basic depth H 1 (as shown in Figure 2) in capture hole 12, and this zoom lens 40 itself has to hold and carries the base altitude H2 of lens 50 away from capture hole 12; Wherein, this basic depth H 1 can be for adjusting the top of zoom lens 40 and the relative spacing h1 between capture hole 12 between stretching tube 20 and camera lens stack shell 30, so that lens 50 places form visual focus P; According to this, the pass between described relative spacing h1 and basic depth H 1 is: 0＜h1＜=H1, and described base altitude H2, relative spacing h1 and the triangular pass of focal distance f 1 are: 0＜(H2+h1)=f1.

please continue and consult 3, disclose the key diagram of device shown in Figure 1 after stretching, but illustrate drawing fixedly all-in-one-piece sampling image lens 10 move up with stretching tube 20, and make between stretching tube 20 and camera lens stack shell 30 produce relative to away from stretching move, the relative spacing h2(that adds in great achievement Fig. 3 as the relative spacing h1 in Fig. 2 is h2〉h1, and meet 0＜h2＜=H1 relational expression) time, have the effect that increases focal distance f 2 (be f2〉f1, and meet 0＜(H2+h2)=f2 relational expression), according to this, can make the profile size of imaging 81 of tested object 80 in Fig. 2 relatively less than the imaging 82 of tested object 80 in Fig. 3.Therefore, application the utility model, the adjustable focal length scope of the commercially available CCD sampling image lens that not only can increase, the enlargement ratio of the commercially available CCD sampling image lens picked-up imaging of can also increasing.

In addition, Fig. 1 is consulted in R. S. V. P., is provided with at least one O shape between the cell wall that described cylinder groove 23 is described and the outer wall of camera lens stack shell 30 and encircles.In particular, the cell wall of this groove 23 is provided with an O shape ring 61 of the outer wall of a contact camera lens stack shell 30, and the outer wall of this camera lens stack shell 30 is provided with the 2nd O shape ring 62 of the cell wall of a contact cylinder groove 23.According to this, please remerge and consult Fig. 2 and Fig. 3, illustrate when a described O shape ring 61 can produce relative stretching running with the 2nd O shape ring 62 between stretching tube 20 and camera lens stack shell 30, avoid the cell wall of a groove 23 and the outer wall of camera lens stack shell 30 to be infected with dust.

Except this implemented, the utility model also was embodied as sampling image lens 10 fixing, and moving lens stack shell 30 produces relative displacements, similarly can reach the adjusting focal length scope or zoom in or out the effect of imaging multiplying power.

Above explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, in the situation that do not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all falling into protection domain of the present utility model.
