Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a light source with an adjustable rotating mounting bracket. Background Technology

[0002] Laboratories typically require multiple light sources mounted on the ceiling in various directions. By changing the angle of these light sources, multi-directional illumination can be achieved to meet experimental requirements. Since the angle of the light sources needs frequent adjustment, they are usually equipped with rotatable mounting brackets. These brackets not only facilitate heat dissipation but also allow for adaptive adjustment of the light source's intensity and angle based on its size, ensuring stability and lifespan. However, simply relying on a rotating shaft cannot guarantee the correct rotation angle, especially for laboratory light sources which require high precision in their illumination angle and frequent movement and rotation. For example, Chinese patent document CN202020074766.5 discloses a fixture for surface light source detection, including a base with a vertical support rod. A fixed outer frame is connected to the vertical support rod, and a detachable mounting seat is installed on the fixed outer frame. The light source is mounted in the mounting seat. The base also has a mounting sliding groove opposite the vertical support rod, with screws in the groove to secure the measuring device to the base. It can simultaneously fix measuring equipment and light source; the distance between the light source and measuring equipment is adjustable; it can be adapted to measuring equipment of various sizes; by changing the light source mounting block, light sources of various sizes can be tested; the mounting block method makes it convenient to place and remove the light source. However, frequent angular rotation can easily cause wear on the rotating shaft, affecting the stability of use. At the same time, frequent and excessive rotation can also easily cause the wire harness between the light source and the bracket to be overstretched and broken, resulting in damage to the light source and affecting the stability and safety of its use.

[0003] Therefore, it is necessary for those skilled in the art to provide a light source with an adjustable rotating mounting bracket to prevent the wiring harness from breaking during long-term rotation experiments, and to prevent the shaft from separating, thereby improving the stability and safety of the light source. Utility Model Content

[0004] The purpose of this invention is to provide a light source with an adjustable rotating mounting bracket, in order to solve the technical problems in the prior art where frequent angular rotation between the light source and the bracket easily leads to wear on the rotating shaft and excessive stretching of the wire harness, causing it to break.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a light source with an adjustable rotating mounting bracket, including a light source box and an adjustable rotating mounting bracket installed outside the light source box.

[0007] Furthermore, the horizontal angle disc includes a mounting shaft and a scale body. The mounting shaft is fitted and connected inside the scale center shaft. The scale body has a scale in the circumferential direction. The scale body is located on the side of the adjusting arm away from the scale center shaft. A thrust bearing is also provided between the scale body and the adjusting arm. One side of the thrust bearing abuts against the scale body, and the other side of the thrust bearing abuts against the side of the adjusting arm.

[0008] Furthermore, the diameter of the dial body is greater than the width of the adjusting arm, a portion of the circumferential side of the dial body protrudes outside the adjusting arm, and a horizontal scale pointer is detachably connected to the edge of the adjusting arm, with the end of the horizontal scale pointer extending to the outer edge of the scale of the dial body.

[0009] Furthermore, a locking ring is also fitted on the mounting shaft of the horizontal angle plate. The locking ring is located on the upper surface of the adjusting arm facing the scale center axis. The locking ring is detachably connected to the adjusting arm and can rotate around the scale center axis with the adjusting arm. A locking hole is provided in the circumferential direction of the locking ring. The locking hole penetrates the wall of the locking ring. A horizontal locking wrench is threaded in the locking hole.

[0010] Furthermore, a wire channel is provided axially inside the horizontal angle plate, the wire channel penetrates the wall of the horizontal angle plate, one end of the wire channel is connected to the scale center axis, and the other end of the wire channel is directly opposite the light source box. A wire is provided inside the scale center axis, and a wire bundle hole is provided on the top surface of the light source box. The wire bundle hole is coaxially arranged with the wire channel.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please see Figure 1 This utility model provides a light source with an adjustable rotating mounting bracket, including a light source box 1 and an adjustable rotating mounting bracket installed outside the light source box 1. The light source box 1 can be rotatably mounted on the adjustable rotating mounting bracket along two coordinate axes.

[0025] The adjustable rotating mounting bracket includes an adjusting arm 2 and a scale center shaft 3. The scale center shaft 3 is a hollow cylindrical structure. One end of the scale center shaft 3 is fixedly connected to a wall. The adjusting arm 2 is rotatably mounted on the scale center shaft 3 around its axis. The light source box 1 is mounted on the adjusting arm 2, and simultaneously, the light source box 1 is rotatably mounted on the adjusting arm 2 in a direction perpendicular to the axis of the scale center shaft 3. This allows the light source box 1 to rotate around two coordinate axes.

[0026] The adjusting arm 2 has a U-shaped frame structure, with the scale center shaft 3 installed in the middle of the adjusting arm 2. At the same time, the two ends of the adjusting arm 2 are respectively installed on both sides of the light source box 1, so that the light source box 1 is subjected to uniform force on the adjustable rotating mounting bracket and the rotation stability is guaranteed.

[0027] Further, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 The adjusting arm 2 has a through hole 21 in the middle, which penetrates the wall of the adjusting arm 2. The scale center shaft 3 is located above the adjusting arm 2 and directly opposite the through hole 21. A horizontal angle disk 31 is slidably provided at one end of the scale center shaft 3 facing the adjusting arm 2. One end of the horizontal angle disk 31 passes through the through hole 21 and is plugged into the adjusting arm 2. The other end of the horizontal angle disk 31 can abut against the bottom wall of the adjusting arm 2.

[0028] The horizontal angle disc 31 includes a mounting shaft 311 and a scale disc 312. The diameter of the mounting shaft 311 is smaller than that of the through hole 21. The mounting shaft 311 passes through the through hole 21 and is fitted into the scale center shaft 3. The diameter of the scale disc 312 is larger than that of the through hole 21. The scale disc 312 has graduations (not shown in the figure) on its circumference to facilitate accurate rotation by the operator. The scale disc 312 is located on the side of the adjusting arm 2 away from the scale center shaft 3. A thrust bearing 4 is also provided between the scale disc 312 and the adjusting arm 2. One side of the thrust bearing 4 abuts against the scale disc 312, and the other side of the thrust bearing 4 abuts against the side of the adjusting arm 2, so that the adjusting arm 2 can rotate relative to the axis of the scale center shaft 3.

[0029] In this embodiment, the horizontal angle disk 31 is provided with a first mating hole 313, which penetrates the wall of the horizontal angle disk 31. The scale center shaft 3 is provided with a second mating hole 301, which penetrates the wall of the scale center shaft 3. The second mating hole 301 can be directly opposite the first mating hole 313. In use, a bolt or pin or other locking device is used to pass through the second mating hole 301 and the first mating hole 313 to fix the horizontal angle disk 31 to the scale center shaft 3. Multiple first mating holes 313 and second mating holes 301 are provided and evenly distributed along the axis of the scale center shaft 3. Pins (not shown) are used to align different first mating holes 313 and second mating holes 301 with each other to achieve height adjustment of the horizontal angle disk 31, the adjusting arm 2 and the light source box 1 on it.

[0030] In use, the horizontal angle disk 31 is fixed relative to the scale center axis 3, while the adjusting arm 2 can rotate relative to the axis of the scale center axis 3. When the adjusting arm 2 is rotated, the adjusting arm 2 rotates on the horizontal angle disk 31 using the thrust bearing 4.

[0031] In this embodiment, the diameter of the dial body 312 is larger than the width of the adjusting arm 2, so that part of the circumferential side of the dial body 312 protrudes outside the adjusting arm 2. At the same time, a horizontal scale pointer 6 is detachably connected to the edge of the adjusting arm 2, and the end of the horizontal scale pointer 6 extends to the outside of the scale of the dial body 312. Since the dial body 312 is fixedly set, when rotating the adjusting arm 2, the operator can accurately confirm the rotation angle of the adjusting arm 2 according to the horizontal scale pointer 6, thereby ensuring the accuracy and stability of use.

[0032] Furthermore, a locking ring 32 is fitted onto the mounting shaft 311 of the horizontal angle disc 31. The locking ring 32 is located on the upper surface of the adjusting arm 2 facing the scale center axis 3. The locking ring 32 is detachably connected to the adjusting arm 2 using fasteners such as bolts or screws, so that the locking ring 32 can rotate around the scale center axis 3 along with the adjusting arm 2. The locking ring 32 has a locking hole 33 in the circumferential direction, which penetrates the wall of the locking ring 32. A horizontal locking wrench 5 is threaded into the locking hole 33, and the end of the horizontal locking wrench 5 can pass through the locking hole 33 and abut against the circumferential side wall of the mounting shaft 311. Thus, when the adjusting arm 2 rotates to the designated position, rotating the horizontal locking wrench 5 causes the end of the horizontal locking wrench 5 to abut against the circumferential side wall of the mounting shaft 311, thereby locking the adjusting arm 2.

[0033] Furthermore, a wire channel 314 is provided axially within the horizontal angle disk 31, penetrating the wall of the horizontal angle disk 31. One end of the wire channel 314 is connected to the scale center shaft 3, and the other end of the wire channel 314 is directly opposite the light source box 1. A wire (not shown in the figure) is provided within the scale center shaft 3, and the wire is used to electrically connect to the light source inside the light source box 1.

[0034] The top surface of the light source box 1 is provided with a wire-binding hole 9, which is coaxially arranged with the wire channel 314. The wire-binding hole 9 ensures that the wire is perpendicular to the center line of the wire channel 314, preventing the wire from being twisted during long-term rotation experiments.

[0035] Please see Figure 7 The side of the light source box 1 is detachably connected to a rotating shaft 11, and a side angle plate 7 is fitted over the rotating shaft 11. The side angle plate 7 is detachably connected to the end of the adjusting arm 2 by fasteners such as bolts or screws. The rotating shaft 11 is rotatably mounted inside the side angle plate 7. The side angle plate 7 is provided with a scale.

[0036] In use, the angle of the light source box 1 can be adjusted by rotating the light source box 1 around the axis of the side angle plate 7.

[0037] Furthermore, the rotating shaft 11 is also provided with an angle locking screw 8, which can be used to lock the rotating shaft 11 and the side angle plate 7 into one piece. The specific locking method of the angle locking screw 8 can be found in a locking mechanism disclosed in patent CN220488091U. The specific structure will not be limited here.

[0038] In another embodiment, a slider (not shown) is provided radially inside the rotating shaft 11. One end of the slider can abut against the inner ring wall of the side angle disk 7, and the other end of the slider can abut against the angle locking screw 8. By rotating the angle locking screw 8, the slider is pushed against the inner ring wall of the side angle disk 7, thereby locking the rotating shaft 11 and the side angle disk 7 into one piece.

[0039] In other embodiments, the angle locking screw 8 can be mounted on the side angle plate 7. One end of the angle locking screw 8 passes through the side angle plate 7 and abuts against the side wall of the light source box 1, while the other end abuts against the side angle plate 7. In use, the side angle plate 7 is fixed relative to the adjusting arm 2. When the light source box 1 rotates to the designated position within the adjusting arm 2, the angle locking screw 8 is rotated so that the end of the angle locking screw 8 abuts against the side wall of the light source box 1, thereby fixing the light source box 1 relative to the adjusting arm 2 and achieving positioning.

[0040] In this embodiment, a fall protection wire 10 is provided on the top surface of the light source box 1. One end of the fall protection wire 10 is detachably connected to the top surface of the light source box 1, and the other end of the fall protection wire 10 is installed on the adjusting arm 2. The fall protection wire 10 is used to prevent the light source box 1 from falling off the adjusting arm 2 and to ensure safety during use.

[0041] This invention uses a scale on its own to identify the adjustable mechanism, and then uses locking structures to fix it, ensuring accurate positioning. By adding adjustable horizontal and angular positions, this invention changes the original fixed installation of the light source to one where the top of the light source can rotate freely left and right horizontally via a central rotating shaft, and the sides can be tilted up and down via angle dials on both sides of the light source, thus meeting a wider range of irradiation experiment requirements.

[0042] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
