Description

Technical Field

[0001] This utility model relates to the field of optical testing technology, and more specifically, to an optical adjustment testing mechanism. Background Technology

[0002] In current laboratory experiments, light is often required. Traditionally, light is projected onto experimental materials by passing a light source through an optical lens. However, different experimental materials require different light. Current optical testing mechanisms, such as the optical lens testing mechanism with patent publication number CN218298759U, cannot adjust the distance between the optical lens and the light source during experiments. If different light conditions are required, such as light that can be obtained by adjusting the distance between the optical lens and the light source, another optical lens must be installed to achieve the desired light. This is too cumbersome and has poor adaptability to different scenarios. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This utility model provides an optical adjustment testing mechanism, such as... Figure 1 As shown, it includes: a mounting base 1, an optical lens 2, a light source assembly 3 for projecting light onto the optical lens 2, and an adjustment assembly 4 for adjusting the distance between the optical lens 2 and the light source assembly 3; the light source assembly 3 is disposed on the mounting base 1; the adjustment assembly 4 is slidably disposed on the light source assembly 3; and the optical lens 2 is detachably disposed on the adjustment assembly 4.

[0022] Specifically, the distance between the optical lens 2 and the light source 32 is adjusted by adjusting component 4 to achieve light under different usage requirements. The adjustment method of component 4 is convenient and quick, without the need for additional operation steps, and the adjustment accuracy is precise and efficient, which can meet the usage requirements under various conditions. The installation method of optical lens 2 is simple and quick, and different optical lenses 2 can be replaced according to actual usage requirements, further improving the applicability of the optical testing mechanism.

[0023] Specifically, the optical lens 2 can be a convex lens, a concave lens, etc., and can be selected according to actual usage requirements.

[0024] Further, the adjustment assembly 4 includes: an adjustment seat 41, an adjustment knob 42, a mounting plate 43, a limiting bolt 44, a first support column 45, a second support column 46, and a tension spring 47; the optical lens 2 is detachably mounted on the adjustment seat 41; the adjustment seat 41 is slidably mounted on the light source assembly 3; the adjustment knob 42 is mounted on the adjustment seat 41 and threadedly connected to the light source assembly 3; the mounting plate 43 is mounted on the adjustment seat 41; the mounting plate 43 has a limiting groove for limiting the limiting bolt 44; the limiting bolt 44 is mounted on the light source assembly 3 and located within the limiting groove; when the limiting bolt 44 abuts against the mounting plate 43, the mounting plate 43 abuts against the light source assembly 3; the first support column 45 is mounted on the light source assembly 3; the second support column 46 is mounted on the adjustment seat 41; one end of the tension spring 47 is fixedly connected to the first support column 45, and the other end is fixedly connected to the second support column 46.

[0025] Specifically, such as Figure 2 As shown, when it is necessary to adjust the distance between the optical lens 2 and the light source 32, simply turn the adjustment knob 42 to move the adjustment seat 41. After adjusting to slightly beyond the required adjustment distance, stop rotating the adjustment knob 42. At this time, the tension spring 47 is in a stretched state and will slowly pull the adjustment seat 41 back in the opposite direction. During the slow pull-back process, when it moves to the adjusted distance, tighten the limit bolt 44 to stop the adjustment seat 41 from moving and fix it in this position, thus completing the adjustment. Fine adjustments made by using the tension spring 47 can make the adjustment more accurate and convenient.

[0026] Specifically, such as Figure 2 As shown, when it is necessary to reset the adjustment seat 41, simply loosen the limit bolt 44 so that it no longer abuts against the mounting plate 43. At this time, the adjustment knob 42 can be rotated, and the tension spring 47, being in a stretched state after adjustment, will drive the adjustment seat 41 to reset on the light source fixing seat 31, so that it is reset to the initial position.

[0027] Specifically, in this embodiment, there are two first pillars 45, two second pillars 46, and two tension springs 47, which are arranged opposite to each other on the adjustment seat 41; the two sets of tension springs 47 provide more balanced and slower elastic force, so that the adjustment seat 41 can adjust the position of the optical lens 2 and the light source 32 with higher precision.

[0028] Further, the light source assembly 3 includes: a light source mounting base 31 and a light source 32; the light source 32 is disposed on the light source mounting base 31; the light source mounting base 31 is detachably connected to the mounting base 1; a guide rail 33 is disposed on the light source mounting base 31; an adjusting base 41 is slidably disposed on the guide rail 33; an adjusting knob 42 is threadedly connected to the light source mounting base 31; a limiting bolt 44 is detachably disposed on the light source mounting base 31; when the limiting bolt 44 abuts against the mounting plate 43, the mounting plate 43 abuts against the light source mounting base 31.

[0029] Specifically, such as Figure 2 As shown, the light source 32 can emit light stably; the guide rail 33 on the light source mounting base 31 ensures that the position of the adjusting base 41 will not deviate during the adjustment process; when the adjustment is in the appropriate position, the mounting plate 43 abuts against the light source mounting base 31, thereby locking the position of the adjusting base 41 at this time.

[0030] Specifically, such as Figure 2 As shown, the adjustment knob 42 is a fine-tooth micro-adjustment knob, which is threadedly connected to the light source mounting base 31. During rotation, it will drive the adjustment base 41 to move in the forward or reverse direction.

[0031] Furthermore, a power supply rail 34 is also provided on the light source mounting base 31.

[0032] Specifically, such as Figure 2 As shown, the power supply rail 34 guides the power supply line of the light source 32 to prevent the power supply line from interfering with the optical experiment.

[0033] Furthermore, the light source 32 and the optical lens 2 are coaxially arranged at their center.

[0034] Specifically, such as Figure 2 As shown, in order to achieve better lighting effects, the light projected by the light source 32 and the center part of the light lens are set coaxially to achieve better lighting effects.

[0035] Furthermore, the tension spring 47 and the adjusting seat 41 are arranged in parallel.

[0036] Specifically, such as Figure 2As shown, the tension spring 47 and the adjusting seat 41 are arranged in parallel, which makes their stroke smoother during the adjustment or reset process, and allows for more precise adjustment of the distance between the optical lens 2 and the light source 32.

[0037] Furthermore, the adjusting seat 41 is provided with a plurality of mounting bolt holes for installing the second support column 46.

[0038] Specifically, such as Figure 2 As shown, the tension of the spring 47 on the adjustment seat 41 can be adjusted according to the different positions of the second pillar 46 installed on the adjustment seat 41, so as to better meet the actual use requirements and further improve the applicability and scenario adaptability of the optical testing mechanism.

[0039] Furthermore, a scale 5 is provided on the same side of both the light source fixing base 31 and the adjusting base 41.

[0040] Specifically, such as Figure 2 As shown, during the adjustment process, the adjustment distance can be more accurately controlled by the scale 5 on the side, without the need for additional measuring components.

[0041] In the specific implementation process, when it is necessary to adjust the distance between the optical lens 2 and the light source 32: First, loosen the limiting bolt 44 so that it no longer abuts against the mounting plate 43. At this time, the adjusting seat 41 can move on the light source fixing seat 31. By rotating the adjusting knob 42, the adjusting seat 41 can move on the guide rail 33 of the light source fixing seat 31. The adjustment distance can be controlled by the scale 5 on one side of the adjusting seat 41 and the light source fixing seat 31. When the distance moved by the adjusting seat 41 slightly exceeds the distance to be adjusted, stop rotating the adjusting knob 42. The elastic force of the tension spring 47 will make the adjusting seat 41 slowly move back. When it moves to the distance to be adjusted, tighten the limiting bolt 44 so that it abuts against the mounting plate 43. At this time, the mounting plate 43 also abuts against the light source fixing seat 31, thus completing the position locking of the adjusting seat 41.

[0042] When the experiment ends and the position of the adjusting seat 41 needs to be reset: loosen the limiting bolt 44 so that it no longer abuts against the mounting plate 43. At this time, the adjusting seat 41 can move on the light source fixing seat 31. By rotating the adjusting knob 42 in the opposite direction and under the elastic force of the tension spring 47, the adjusting seat 41 continuously resets and moves until the adjusting seat 41 is reset to the initial position and the tension spring 47 is in a balanced state. At this time, the reset of the adjusting seat 41 is completed.

[0043] This utility model discloses an optical adjustment testing mechanism that uses an adjustment component 4 to adjust the distance between the optical lens 2 and the light source 32, thereby projecting the light required for the actual experiment without the need to replace the optical lens 2. Both the adjustment component 4 and the light source component 3 are provided with a scale 5 on one side, which can be used to further increase the adjustment accuracy during the adjustment process and achieve better experimental results.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
