The utility model provides a kind of focusing lens component 100, please refers to Fig. 1 and Fig. 2, and Fig. 1 is that the utility model one is real The schematic perspective view of an immunity analysis instrument is applied, Fig. 2 is the schematic cross-sectional view of the focusing lens component in Fig. 1.

In the present embodiment, focusing lens component 100 may include the first fixing piece 10 and amasthenic lens 20.

Wherein, the first fixing piece 10 includes main part 11 and the supporting sleeve 12 that connect with main part 11, on main part 11 It is formed with the first threaded hole 112, supporting sleeve 12 and the first threaded hole 112 are coaxially disposed.Amasthenic lens 20 includes first segment 21 With second segment 22, external screw thread is formed on first segment 21, external screw thread and the first threaded hole 112 are cooperatively connected, so that amasthenic lens 20 can be along the axial movement of the first threaded hole 112, to adjust the focal length of amasthenic lens 20, second segment 22 is connected to supporting sleeve On 12 inner sidewall.

The utility model is respectively arranged with first with the cooperation of the first segment 21 of amasthenic lens 20 on the first fixing piece 10 Threaded hole 112 and the supporting sleeve 12 cooperated with the second segment 22 of amasthenic lens 20, on the one hand, the first threaded hole 112 and first The cooperation of section 21 can be in order to adjusting and fixed-focus camera lens 20；On the other hand, supporting sleeve 12 is connected to amasthenic lens 20 It is also possible to prevent to cause the axis direction of amasthenic lens 20 to occur when the first threaded hole 112 cooperates with first segment 21 on second segment 22 The phenomenon that offset, occurs.

Specifically, in the present embodiment, as shown in Fig. 2, amasthenic lens 20 further includes third section 23.Wherein, third section 23 The two sides of second segment 22 are separately positioned on first segment 21.Wherein, amasthenic lens 20 is hollow structure, and amasthenic lens 20 also wraps Optical mirror slip 24 is included, side of the third section 23 far from second segment 22 is arranged in optical mirror slip 24, for receiving scattering light.

Wherein, optical mirror slip 24 can be convex lens, and convex lens is fixed in the third section 23 of amasthenic lens 20.It is specific and Speech, convex lens are fixed on the end position of the one end of third section 23 far from second segment 22.

In the present embodiment, third section 23 and first segment 21 are separately positioned on the two sides of second segment 22.Correspondingly, it props up The side of the close third section 23 of main part 11 is arranged in support set pipe 12, and second segment 22 is connected to the inner sidewall of supporting sleeve 12 On.Second segment 22 is arranged between first segment 21 and third section 23, the supporting to amasthenic lens 20 of supporting sleeve 12 can be made The middle position that active force acts on amasthenic lens 20 is connect, so that amasthenic lens 20 axially retains effect more preferably.

Optionally, the outer diameter of second segment 22 is greater than the outer diameter of first segment 21 and third section 23.Pass through setting second segment 22 Outer diameter is greater than the outer diameter of first segment 21 and third section 23, on the one hand can be in order to assembling amasthenic lens 20；On the other hand, support sleeve Pipe 12 be relatively large in diameter or the second segment 22 of amasthenic lens 20 provides biggish support torque, and then reduce mobile focus Frictional force when camera lens 20 between second segment 22 and supporting sleeve 12, so that the adjusting of amasthenic lens 20 is more smooth.

Optionally, the difference that the internal diameter of supporting sleeve 12 and the outer diameter of second segment 22 is arranged is 0-0.05mm.For example, can be with For 0mm, 0.01mm, 0.02mm, 0.03mm, 0.04mm or 0.05mm etc..Preferably, the internal diameter and second of supporting sleeve 12 is set The difference of the outer diameter of section 22 is 0-0.02mm.For example, in one embodiment, the internal diameter and second segment of supporting sleeve 12 can be set The difference of 22 outer diameter is 0mm, and the outer diameter of the internal diameter and second segment 22 that indicate supporting sleeve 12 is equal in magnitude.In another implementation In example, the difference that the internal diameter of supporting sleeve 12 and the outer diameter of second segment 22 can be set is 0.02mm, indicates supporting sleeve 12 Internal diameter be greater than second segment 22 outer diameter, and the inner diameter values of supporting sleeve 12 subtract second segment 22 outer diameter value be equal to 0.02mm. By can reduce the frictional force between supporting sleeve 12 and second segment 22 for 22 clearance fit of supporting sleeve 12 and second segment, So that the adjusting of amasthenic lens 20 is more smooth.
