[0002] Lasers are widely used in industrial processing, agriculture, optical communication and medical fields. Currently, the visible light indicator devices commonly on the market can ensure that the laser and visible light are coaxial by installing them at the laser's output emission port. However, the red light emitter on the indicator device is mostly fixed and difficult to adjust later. Moreover, because the light shines on the mirror surface, the indicator has a high temperature when working and lacks a heat dissipation structure design, which affects the service life of the indicator device. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a red light spot position indicator.

[0004] A red light dot position indicator includes: a lens holder and a red light holder. The red light holder is mounted on the lens holder, and a lens is mounted on the lens holder. The angle between the lens mounting direction and the horizontal direction is 45 degrees. The red light holder has a mounting slot, and a red light emitter is mounted on the mounting slot. The red light emitter and the lens are located on the same optical path. The red light holder also has multiple adjustment holes, which extend from the outside of the red light holder to the mounting slot. The adjustment holes have threads inside, and adjustment screws are fitted inside the adjustment holes. The lens holder also has a heat dissipation groove.

[0005] Furthermore, the adjustment holes include a first adjustment hole, a second adjustment hole, a third adjustment hole, and a fourth adjustment hole, with the first and third adjustment holes being symmetrically positioned, and the second and fourth adjustment holes being symmetrically positioned.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1-5The red light dot position indicator shown includes: a lens mounting base 1 and a red light mounting base 2. The red light mounting base 2 is mounted on the lens mounting base 1. A lens 3 is mounted on the lens mounting base 1. The angle between the mounting direction of the lens 3 and the horizontal direction is 45 degrees, that is, the lens 3 is mounted at a 45-degree angle for reflecting light. The red light mounting base 2 has a mounting slot, and a red light emitter 5 is mounted on the mounting slot. The red light emitter 5 and the lens 3 are located on the same optical path to ensure the transmission of red light. The red light mounting base 2 also has multiple adjustment holes for adjusting the position of the red light emitter 5. The adjustment holes extend from the outside of the red light mounting base 2 to the mounting slot. The adjustment holes have threads inside and adjustment screws are installed inside the adjustment holes. The lens mounting base 1 also has multiple heat dissipation grooves 7, which are evenly spaced on the outer wall of the lens mounting base 1.

[0028] The aforementioned red light position indicator, by opening multiple adjustment holes on the red light mounting base 2 and installing adjustment screws in the adjustment holes, allows for minute adjustments to the installation position of the red light emitter 5 by controlling the different displacement and elongation of the different screws, thereby improving the flexibility of use. The heat on the lens 3 is transferred to the lens mounting base 1. By opening heat dissipation grooves 7 on the lens mounting base 1, the contact area between the lens mounting base 1 and the external air is increased, improving the heat exchange rate. Even during long-term use, the indicator can dissipate heat in time, ensuring the service life of the indicator.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the adjustment holes include a first adjustment hole 201, a second adjustment hole 202, a third adjustment hole 203, and a fourth adjustment hole 204. The positions of the first adjustment hole 201 and the third adjustment hole 203 are symmetrical, and the positions of the second adjustment hole 202 and the fourth adjustment hole 204 are also symmetrical. Through the four symmetrically arranged adjustment holes, set screws are installed in the holes with threads to ensure that the set screws are balanced in pairs. By rotating the set screws, their displacement is controlled, thereby controlling the elongation of the set screws in the mounting slot, thus achieving the clamping of the red light emitter 5 in different mounting positions. This also realizes the micro-adjustment of the mounting position, improving the flexibility of the use process. It should be noted that the mounting position here is only a micro-adjustment and does not involve a large displacement adjustment. Therefore, it can ensure the stable clamping of the red light emitter 5 within the micro-adjustment range.

[0030] like Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the lens mounting base 1 has symmetrically provided lens mounting slots 8 inside, and the lens 3 is installed on the lens mounting slots 8. The lens mounting slots 8 are specifically provided on the inner wall of the lens mounting base 1. By setting the lens mounting slots 8, the lens 3 can be stably installed. The lens mounting slots 8 also have a 45-degree angle with the light outlets at both ends of the lens mounting base 1, so that the lens 3 is installed at a 45-degree angle.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the position indicator also includes a cover plate 4, which is mounted on the red light mounting base 2. The red light mounting base 2 is also provided with a plurality of second connection holes 207, and the cover plate 4 is connected to the red light mounting base 2 through the second connection holes 207. During assembly, the second connection holes 207 are used in conjunction with screws for connection and installation. The cover plate 4 mainly serves a protective function and ensures that the position indicator looks more beautiful and smooth, with strong integration. At the same time, the detachable design also facilitates the installation of the internal red light emitter 5.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in this embodiment, the red light mounting base 2 has a wire harness compartment 205, which communicates with the mounting slot. The red light mounting base 2 also has a wire harness through hole, which communicates with the wire harness compartment 205. By designing the wire harness compartment 205 to communicate with the mounting slot, it can be ensured that the wire harness of the red light transmitter 5 is collected in the wire harness compartment 205. This design not only allows the wire harness to be better organized and ensures aesthetics, but also plays a role in protecting the wire harness.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the bottom of the red light fixing base 2 is provided with a light outlet 10, which is located in the optical path between the red light emitter 5 and the lens 3. The setting of the light outlet 10 can ensure the emission of light from the red light emitter 5. At the same time, the light outlet 10 is located in the optical path between the red light emitter 5 and the lens 3, so even if the position of the red light emitter 5 is slightly adjusted under the action of the set screw, the transmission of red light can still be guaranteed.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in this embodiment, the lens mounting base 1 is provided with multiple adapter connection ports 6, and adapters 9 are connected and installed on the adapter connection ports 6. The adapters 9 are used to connect the position indicator to the light outlet of the laser emitter, so as to realize the overlap of the laser target point and the red light target point. The adapter connection ports 6 are also connected by screws to realize the stable connection between the lens mounting base 1 and the light outlet of the laser emitter.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the red light fixing base 2 is provided with a plurality of first connecting holes 206, and the lens fixing base 1 is connected to the red light fixing base 2 through the first connecting holes 206; similarly, screws are used to cooperate with the first connecting holes 206 for installation, thereby realizing the assembly between the lens fixing base 1 and the red light fixing base 2.

[0036] like Figures 1-5 As shown, in this embodiment, during the assembly process, the lens 3 is first inserted into the lens mounting slot 8, and the lens 3 is at a 45-degree angle to the horizontal direction. Then, the red light emitter 5 is installed into the mounting slot on the red light fixing seat 2. The wire harness is located in the wire harness compartment 205. The cover plate 4 is installed on the red light fixing seat 2, and then the red light fixing seat 2 is installed on the lens fixing seat 1. Then, the position indicator is connected to the light outlet of the laser emitter. The position of the red light emitter 5 is finely adjusted by installing set screws in the first adjustment hole 201, the second adjustment hole 202, the third adjustment hole 203 and the fourth adjustment hole 204 distributed around the red light fixing seat 2, so that the red light target point coincides with the laser target point. Multiple heat dissipation slots 7 effectively increase the overall heat dissipation area of ​​the indicator surface, improve the service life of the position indicator, and the overall structure of the device is simple and lightweight. The red light fixing seat 2 adopts an arc-shaped transition design, making the overall appearance surface look smoother and the overall structural curve more rounded. The overall center of gravity of the laser tube is more biased towards the center of the laser tube.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
