Description

Technical Field

[0001] This utility model relates to the field of diffuse reflection light source combination technology, and in particular to a combinable strip diffuse reflection light source. Background Technology

[0002] Diffuse light sources, with their advantages of soft light, uniform illumination, and glare-free illumination, have been widely used in industrial automation inspection, machine vision recognition, and other fields. Among them, strip diffuse light sources, due to their elongated illumination area and strong adaptability, have become the preferred light source type for industrial production line inspections (such as mixed-material inspection of plug-in resistors, appearance inspection of capacitors, and surface inspection of keyboards), lightbox backlighting, and corridor contour lighting. Existing strip diffuse light sources typically employ an arc-shaped diffuse reflector structure, achieving large-area uniform illumination and reaching a fluorescent lamp-like lighting effect. Furthermore, they can be customized to a certain extent in terms of color and length to meet the basic usage requirements of different scenarios.

[0003] However, most existing strip diffuse reflection light sources are integrated fixed structures, with their length, illumination range, and luminous power preset at the factory. They cannot be flexibly adjusted according to changes in actual application scenarios. When used in the same application scenario, the strip diffuse reflection light source needs to be assembled. However, the splicing method of the existing strip diffuse reflection light source is generally to fix it with tape or bolts. After fixing, it is not convenient to adjust the angle between the strip diffuse reflections, thus affecting the illumination effect. Utility Model Content

The second threaded rod is rotatably disposed at the bottom of the second limiting groove. The second threaded rod extends into the limiting block through threaded engagement. The second rotating mechanism is disposed in the first housing and is used to drive the second threaded rod to rotate.

[0010] Based on the above scheme, the second rotating mechanism includes a first gear, a second gear, and a third rotating mechanism. The first gear is rotatably disposed in the first housing and is fixedly connected to the second threaded rod.

[0014] Based on the above scheme, a rubber pad is fixedly provided on the side wall of the mounting block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, by setting a relative moving mechanism and a positioning post, after the mounting block is inserted into the support frame of another light source body, the head of the first internal hexagonal bolt can be turned by an internal hexagonal wrench. Then, the rotation of the first internal hexagonal bolt head can push the positioning post to move and extend into the positioning groove. Thus, the assembly of the light source body can be achieved by the cooperation between the positioning post and the positioning groove and the cooperation between the mounting frame and the mounting block.

[0016] 2. In this utility model, by setting a limiting mechanism, the second internal hexagonal bolt head can be turned by an internal hexagonal wrench, so that the limiting block can move from the second limiting groove and extend into the first limiting groove.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-5 As shown, this utility model embodiment provides a combinable strip diffuse reflection light source, including a light source body 1, a mounting frame 2, a mounting block 4, a first cavity 5, a relative movement mechanism, and a limiting mechanism. A U-shaped mounting frame 2 is fixedly installed on one side wall of the light source body 1. A positioning groove 3 is opened on the side wall of the mounting frame 2 near the light source body 1. A mounting block 4 is fixedly installed on the side wall of the light source body 1 away from the mounting frame 2. The shape of the mounting block 4 is adapted to the inner wall of the mounting frame 2. A first cavity 5 is opened on both sides of the mounting block 4. An installation opening is opened on the side wall of the first cavity 5 away from the mounting block 4. A positioning post 6 is slidably installed in the installation opening. The positioning post 6 is adapted to the shape of the positioning groove 3. The relative movement mechanism is set between the mounting block 4 and the positioning post 6 to drive the two positioning posts 6 to move relative to each other. The limiting mechanism is set on the positioning post 6 to limit the distance between the positioning post 6 and the side wall of the positioning groove 3. A rubber pad is fixedly installed on the side wall of the mounting block 4.

[0028] Reference Figures 1-3The relative movement mechanism includes a first housing 7, a first threaded rod 8, and a first rotation mechanism. The first housing 7 is slidably disposed within a first cavity 5 and is fixedly connected to a positioning post 6. The first threaded rod 8 is rotatably disposed within the first cavity 5 and passes through the first cavity 5 via a threaded engagement. The first rotation mechanism is disposed between the mounting block 4 and the first threaded rod 8 and is used to drive the two first threaded rods 8 to rotate synchronously. The first rotation mechanism includes a second cavity 9, a second bevel gear 12, and a first drive mechanism. The second cavity 9 is opened within the mounting block 4. The inner wall of the second cavity 9 is rotatably disposed with a first bevel gear 10. A first connecting rod 11 is fixedly disposed between the first bevel gear 10 and the first threaded rod 8. The second bevel gear 12 is rotatably disposed on the inner wall of the second cavity 9 and meshes with the first bevel gear 10. The first drive mechanism is disposed on the mounting block 4 and is used to drive the second bevel gear 12 to rotate. The mechanism includes a first drive groove and a first hexagon socket head cap 13. The first drive groove is formed on the side wall of the mounting block 4. The first hexagon socket head cap 13 is rotatably disposed in the first drive groove. A drive rod is fixedly disposed between the first hexagon socket head cap 13 and the second bevel gear 12. Specifically, after the operator inserts the mounting block 4 into the support frame of another light source body 1, the operator can use an Allen wrench to tighten the first hexagon socket head cap 13. The rotation of the first hexagon socket head cap 13 can drive the second bevel gear 12 to rotate. At the same time, the meshing of the second bevel gear 12 with the first bevel gear 10 drives the first connecting rod 11 and the first threaded rod 8 to rotate. Then, the threaded engagement of the first threaded rod 8 with the first housing 7 drives the first housing 7 and the positioning post 6 to move and extend into the positioning groove 3. Thus, the assembly of the light source body 1 can be achieved through the engagement of the positioning post 6 with the positioning groove 3 and the engagement of the mounting bracket 2 with the mounting block 4.

[0029] Reference Figure 4 and Figure 5The limiting mechanism includes a first limiting groove 14, a second limiting groove, a second threaded rod 16, and a second rotating mechanism. The bottom of the positioning groove 3 has multiple first limiting grooves 14 arranged in a ring shape. The end of the positioning post 6 furthest from the mounting block 4 has a second limiting groove. A limiting block 15 is slidably disposed within the second limiting groove. The second threaded rod 16 is rotatably disposed at the bottom of the second limiting groove and extends into the limiting block 15 via a threaded engagement. The second rotating mechanism is disposed within the first housing 7 and is used to drive the second threaded rod 16 to rotate. The second rotating mechanism includes a first gear 17, a second gear 18, and a third rotating mechanism. The first gear 17 is rotatably disposed within the first housing 7 and is fixedly connected to the second threaded rod 16. The second gear 18... The first housing 7 is rotatably mounted on the first housing 7. The second gear 18 meshes with the first gear 17. The third rotating mechanism is mounted on the first housing 7 and is used to drive the second gear 18 to rotate. Specifically, the operation of the third rotating mechanism can drive the second gear 18 to rotate. At the same time, the meshing of the second gear 18 with the first gear 17 drives the first gear 17 and the second threaded rod 16 to rotate. Thus, the threaded engagement between the second gear 18 and the limiting block 15 can drive the limiting block 15 to move and extend into the first limiting groove 14. Thus, the engagement of the limiting block 15 with the first limiting groove 14 and the second limiting groove can realize the limiting and unlocking between the positioning post 6 and the positioning groove 3, thereby facilitating the angle adjustment between the light source body 1.

[0030] Reference Figure 4 and Figure 5The third rotating mechanism includes a spline opening 19, a drive opening 20, a spline rod 21, and a synchronous rotating mechanism. The spline opening 19 is located on the second gear 18, and the drive opening 20 is located on the first housing 7. The spline rod 21 is rotatably disposed within the first cavity 5, passing through the spline opening 19 and the drive opening 20. The spline rod 21 is slidably connected to the side wall of the spline opening 19. The synchronous rotating mechanism is located between the mounting block 4 and the spline rod 21, and is used to drive the two spline rods 21 to rotate synchronously. The synchronous rotating mechanism includes a third cavity, a fourth bevel gear 23, and a second driving mechanism. The third cavity is located within the mounting block 4, and a third bevel gear 22 is rotatably disposed on the inner wall of the third cavity. A second connecting rod is fixedly disposed between the third bevel gear 22 and the spline rod 21. The fourth bevel gear 23 is rotatably disposed on the inner wall of the third cavity, and the fourth bevel gear 23 is slidably connected to the third bevel gear 21. The bevel gear 22 meshes with the fourth bevel gear 23. The second drive mechanism is mounted on the mounting block 4 and is used to drive the fourth bevel gear 23 to rotate. The second drive mechanism includes a second drive groove and a second hexagon socket head 24. The second drive groove is opened on the side wall of the mounting block 4. The second hexagon socket head 24 is rotatably mounted at the bottom of the second drive groove. A second drive rod is fixedly installed between the second hexagon socket head 24 and the fourth bevel gear 23. Specifically, the second hexagon socket head 24 can be turned by using an Allen wrench. The rotation of the second hexagon socket head 24 can drive the fourth bevel gear 23 to rotate. At the same time, the meshing of the fourth bevel gear 23 with the third bevel gear 22 drives the third bevel gear 22, the second connecting rod, and the spline rod 21 to rotate. Thus, the second gear 18 can be driven to rotate through the sliding fit between the spline rod 21 and the side wall of the spline opening 19.

[0031] Working principle: During use, after the operator inserts the mounting block 4 into the support frame of the other light source body 1, they can use an Allen wrench to tighten the first Allen bolt head 13. The rotation of the first Allen bolt head 13 drives the second bevel gear 12 to rotate. Simultaneously, the meshing of the second bevel gear 12 with the first bevel gear 10 drives the first connecting rod 11 and the first threaded rod 8 to rotate. Furthermore, the threaded engagement between the first threaded rod 8 and the first housing 7 causes the first housing 7 and the positioning pin 6 to move and extend into the positioning groove 3. Thus, the assembly of the light source body 1 is achieved through the engagement of the positioning pin 6 with the positioning groove 3 and the engagement of the mounting frame 2 with the mounting block 4. Afterwards, the operator rotates the light source body 1 to adjust the angle between the light source bodies 1. Then, the operator can use an Allen wrench to tighten the second Allen bolt head 13. When the bolt head 24 is tightened, the rotation of the second hex bolt head 24 drives the fourth bevel gear 23 to rotate. Simultaneously, the meshing of the fourth bevel gear 23 with the third bevel gear 22 drives the third bevel gear 22, the second connecting rod, and the spline rod 21 to rotate. Thus, the sliding engagement between the spline rod 21 and the side wall of the spline opening 19 drives the second gear 18 to rotate. The meshing of the second gear 18 with the first gear 17 drives the first gear 17 and the second threaded rod 16 to rotate. Thus, the threaded engagement between the second gear 18 and the limiting block 15 drives the limiting block 15 to move and extend into the first limiting groove 14. Thus, the engagement of the limiting block 15 with the first limiting groove 14 and the second limiting groove respectively achieves the limiting between the positioning post 6 and the positioning groove 3, thereby realizing the angle adjustment between the light source body 1.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
