Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optics, and more specifically, to an optical module with adjustable position. Background Art
[0002] The optical module with multiple lenses combined for reflection is usually fixed on a bracket and its position is not adjustable. When the emission position of the incident light source is offset, the focus point will be affected. Therefore, the utility model proposes an optical module with adjustable position. Utility Model Content
[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and to provide an optical module with adjustable position. The optical module has the characteristics of adjustable distance between lenses and convenient adjustment.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves an optical module with adjustable position, including a first cylindrical lens, a side surface of the first lens is provided with a frame fixed thereto, the frame has an external thread, a barrel is sleeved on the frame, the barrel has an internal thread, the frame is threadedly connected in the barrel, a second lens fixed thereto is provided in the barrel, a center hole is opened on the second lens, the second lens is a concave lens, the end of the first lens facing the second lens is provided with a first reflective film close to the center position, and the end of the second lens facing the first lens is provided with a second reflective film.
[0005] The utility model is further configured as follows: the second lens is arranged at an end of the barrel away from the first lens.
[0006] In summary, the utility model has the following beneficial effects: the position-adjustable optical module involved in the utility model can adjust the focus by changing the distance between the first lens and the second lens when the incident light source slightly deviates from the axial distance of the first lens, so as to ensure the use accuracy of the optical module, the distance between the lenses is adjustable, the adjustment is convenient, the overall function is complete, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0008] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0009] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0010] Example 1
[0011] See also Figure 1 As shown, a position-adjustable optical module involved in this embodiment includes a first cylindrical lens 1, a side of the first lens 1 is provided with a frame 2 fixed thereto, the frame 2 has an external thread, a tube 3 is sleeved on the frame 2, the tube 3 has an internal thread, the frame 2 is threadedly connected in the tube 3, a second lens 4 fixed thereto is provided in the tube 3, a center hole 5 is opened in the second lens 4, the second lens 4 is a concave lens, a first reflective film 6 close to the center position is provided at one end of the first lens 1 facing the second lens, and a second reflective film 7 is provided at one end of the second lens 4 facing the first lens.
[0012] Furthermore, the second lens 4 is disposed at an end of the barrel 3 away from the first lens 1 .
[0013] In this embodiment, by rotating the tube 3 clockwise relative to the frame 2, the tube 3 drives the second lens 4 to move away from the first lens 1; by rotating the tube 3 counterclockwise relative to the frame 2, the tube 3 drives the second lens 4 to move toward the first lens 1.
[0014] The utility model relates to an optical module with adjustable position. When the incident light source slightly deviates from the axial distance of the first lens, the focusing point can be adjusted by changing the distance between the first lens and the second lens to ensure the use accuracy of the optical module. The distance between the lenses is adjustable, the adjustment is convenient, the overall function is complete, and the practicability is strong.
