Description

Technical Field

[0001] This utility model relates to the field of fiber optic collimator technology, and in particular to a fiber optic collimator with angle adjustment. Background Technology

[0002] An optical fiber collimator is an optical device that converts transmitted light within an optical fiber into collimated light, or couples external parallel light into a single-mode optical fiber. It has wide applications in fields such as optical fiber communication, laser processing, and spectral analysis.

[0003] Traditional fiber optic collimators are mostly fixed structures and cannot adjust the optical path angle. If the optical path direction needs to be adjusted to cope with changes in equipment layout, traditional collimators need to be disassembled and reinstalled, which increases maintenance costs and time. They are difficult to adapt to complex and ever-changing application environments and are not conducive to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle-adjustable fiber optic collimator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An angle-adjustable fiber optic collimator includes a fiber optic collimator body and a collimating lens. One end of the fiber optic collimator body is threaded with an anti-slip cover, and the tail end of the fiber optic collimator body is connected to a fiber core body. The fiber optic collimator body has four sliding grooves and one sliding groove. An arc-shaped iron block is installed in the sliding groove. A sliding sleeve is slidably fitted on the outside of the fiber optic collimator body. Connectors are provided at all four ends of the inner wall of the sliding sleeve. The connectors are fixedly connected to the collimating lens. The collimating lens is located inside the fiber optic collimator body. The connectors are slidably located in the sliding groove. A limit component is provided at one end of the sliding sleeve.

[0007] In addition, a preferred structure is that both ends of the connector are provided with tensile dustproof plates, and the other end of the tensile dustproof plate is fixedly connected to one end of the slide groove.

[0008] In addition, a preferred structure is that one end of the sliding sleeve is provided with a hidden groove, a through hole, and a limiting groove, the hidden groove being connected to the through hole, and the through hole being connected to the limiting groove.

[0009] Furthermore, in a preferred configuration, the limiting component includes an arc-shaped magnet, which is located within the second slide groove and attracts the arc-shaped iron block.

[0010] In addition, a preferred structure is that springs are provided at both ends of the top of the arc-shaped magnet, the springs are located in the hidden groove, and the top of the springs are fixedly connected to the top of the hidden groove.

[0011] In addition, a preferred structure is that the top of the arc-shaped magnet is provided with a connecting rod, which is located between two springs and slides through the through hole.

[0012] In addition, a preferred structure is that a circular stop is provided at the top of the connecting rod, the circular stop is located in the limiting groove, and a T-shaped pull rod is provided at the top of the circular stop.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the divergence angle or convergence angle of the light beam is affected by changing the distance between the collimating lens and the light source, thereby indirectly affecting the exit angle of the light beam. When the direction of the optical path needs to be adjusted, there is no need to disassemble and reinstall it. It can cope with complex and ever-changing application environments and is easy to use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-7 An angle-adjustable fiber optic collimator includes a fiber optic collimator body 1 and a collimating lens 6. One end of the fiber optic collimator body 1 is threaded with an anti-slip cover 3, and the tail end of the fiber optic collimator body 1 is connected with a fiber core body 2. The fiber optic collimator body 1 has four sliding grooves 11 and one sliding groove 12. An arc-shaped iron block 5 is installed in the sliding groove 12. A sliding sleeve 4 is slidably fitted on the outside of the fiber optic collimator body 1. Connectors 8 are provided at all four ends of the inner wall of the sliding sleeve 4. The connectors 8 are fixedly connected to the collimating lens 6. The collimating lens 6 is located inside the fiber optic collimator body 1. The connectors 8 are slidably located in the sliding groove 11. A limit component 7 is provided at one end of the sliding sleeve 4.

[0025] The connector 8 is equipped with a tensile dustproof plate 9 at both ends. The other end of the tensile dustproof plate 9 is fixedly connected to one end of the slide groove 11 to prevent dust or debris from entering the fiber optic collimator body 1 and affecting normal use.

[0026] Meanwhile, one end of the sliding sleeve 4 is provided with a hidden groove 41, a through hole 42, and a limiting groove 43. The hidden groove 41 is connected to the through hole 42, and the through hole 42 is connected to the limiting groove 43.

[0027] Furthermore, the limiting component 7 includes an arc-shaped magnet 71, which is located in the slide groove 12 and attracts the arc-shaped iron block 5, so that the limiting component 7 can limit the position of the slide sleeve 4, thereby limiting the position of the collimating lens 6, which facilitates the use of the fiber optic collimator.

[0028] Meanwhile, springs 73 are provided at both ends of the top of the arc magnet 71. The springs 73 are located in the hidden groove 41, and the top of the springs 73 are fixedly connected to the top of the hidden groove 41. The springs 73 further restrict the position of the sliding sleeve 4.

[0029] Meanwhile, a connecting rod 72 is provided on the top of the arc-shaped magnet 71. The connecting rod 72 is located between the two springs 73 and slides through the through hole 42.

[0030] Furthermore, a circular stop 74 is provided at the top of the connecting rod 72. The circular stop 74 is located in the limiting groove 43. A T-shaped pull rod 75 is provided at the top of the circular stop 74. Pulling the T-shaped pull rod 75 will cause the connecting rod 72 to move synchronously.

[0031] In this embodiment, when it is necessary to adjust the exit angle of the optical path, the T-shaped lever 75 is pulled upward to drive the connecting rod 72 to move synchronously. The arc magnet 71 will then leave the arc iron block 5, thereby squeezing the spring 73, and then pushing the sliding sleeve 4 to move, driving the collimating lens 6 to move within the fiber collimator body 1. When it moves to the appropriate position, the T-shaped lever 75 is slowly loosened. The arc magnet 71 slowly moves downward under the elastic reset action of the spring 73 until the arc magnet 71 and the arc iron block 5 are attracted together. At this time, the sliding sleeve 4 is limited by the action of the spring 73 and the arc magnet 71. The collimating lens 6 moves within the fiber collimator body 1, thereby changing the distance between the collimating lens 6 and the fiber core body 2, thus affecting the divergence angle or convergence angle of the beam, and indirectly affecting the exit angle of the beam. This realizes the adjustment of the beam exit angle of the fiber collimator, which is convenient for use in complex and ever-changing application environments.

[0032] In this invention, by changing the distance between the collimating lens 6 and the light source, the divergence angle or convergence angle of the light beam is affected, which indirectly affects the exit angle of the light beam. When the direction of the optical path needs to be adjusted, there is no need to disassemble and reinstall it. It can cope with complex and ever-changing application environments and is easy to use.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
