Abstract
Description
Technical Field
[0001] This utility model relates to the field of random laser experimental equipment, specifically to an adjustable random laser sample holder. Background Technology
[0002] A random laser is a special type of laser that operates based on stimulated emission amplification, which occurs when light undergoes multiple scattering in a disordered gain system. The internal structure of a random laser is complex and random, and when energy is supplied, it emits a very unique light pattern. A random laser consists of three main parts: a laser medium, a pump source, and a random feedback loop. Unlike traditional lasers, random lasers only require a pump source and gain medium, not a resonant cavity. A random laser sample can be prepared by injecting a mixed solution of dye and liquid crystal into a liquid crystal cell made of two transparent glass plates bonded together through capillary action. This random laser sample can emit a special spectrum under the illumination of an external light source. For the convenience of experimental use, dyes and other materials are usually mixed directly to make a transparent gel-like sample. Such samples are usually soft and vary in thickness. They are usually made into sheets or filaments to facilitate multiple sets of comparative experiments. However, the clamping force of existing fixtures is affected by the thickness of the sample. Thin samples are subject to less clamping force and are easy to detach from the fixture, while thick samples are subject to greater clamping force. Excessive clamping force can easily damage the sample. Moreover, existing fixtures are not easy to adjust the position of the sample, making the experimental process inconvenient and difficult to meet experimental requirements. Utility Model Content

Detailed Implementation
[0021] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.
[0022] Example 1:
[0023] Reference Figures 1 to 6 This utility model provides an adjustable random laser sample holder, including a support frame 1, an adjustment frame 2, and two slides 3 movably mounted on the adjustment frame 2. One end of the adjustment frame 2 is rotatably mounted on the support frame 1. The support frame 1 is provided with an adjustment mechanism 4 for fixing the angle position of the adjustment frame 2. A folding plate 31 is rotatably mounted on the slides 3. The middle part of the folding plate 31 is rotatably connected to the slides 3. A fixing plate 32, an elastic element 33, and a fastener 34 are provided on the slides 3. The fastener 34 is used to fix the slides 3 on the adjustment frame 2. A pad 5 is detachably mounted on the fixing plate 32. The elastic element 33 acts on the folding plate 31 to drive one end of the folding plate 31 to elastically abut against the pad 5.
[0024] In use, the two slides 3 can be fixed by fasteners 34 on the two slides 3 respectively so that the distance between the two slides 3 can be adjusted according to the sample length. It is suitable for clamping samples of different lengths. Based on the structure of the folding plate 31 rotating on the slide 3, applying force to rotate one end of the folding plate 31 can drive the other end of the folding plate 31 away from the pad 5. After the sample is placed at the gap between the folding plate 31 and the pad 5, the external force is removed. The elastic element 33 acts on the folding plate 31 to drive one end of the folding plate 31 to elastically abut against the pad 5 to clamp the sample. Different sizes of pads 5 can be replaced to adjust the clamping force between the folding plate 31 and the pad 5. The angle position of the sample can be adjusted by adjusting the angle position of the adjusting frame 2 through the adjusting mechanism 4 as needed, which facilitates experimental operation and meets experimental requirements.
[0025] Example 2:
[0026] Reference Figures 1 to 6 In conjunction with the technical solution of Embodiment 1, in this embodiment,
[0027] The adjusting frame 2 is provided with a mounting column 6, and the support frame 1 is provided with a mounting cylinder 7 for the mounting column 6 to be rotated and installed. The adjusting mechanism 4 is provided on the mounting cylinder 7 and is used to clamp the mounting column 6.
[0028] After rotating the adjustment frame 2 to the designated position as needed, the entire adjustment frame 2 can be fixed by clamping the mounting column 6 through the adjustment mechanism 4, thereby adjusting the angle of the adjustment frame 2 and thus adjusting the angle of the clamped sample.
[0029] Specifically, the adjusting mechanism 4 includes a threaded cap 41 and an elastic plate 42. The mounting cylinder 7 is provided with several mounting grooves 71, and an elastic plate 42 is rotatably installed in each mounting groove 71. One end of the elastic plate 42 is rotatably connected to the mounting groove 71. The elastic plate 42 is provided with a pressure plate 421 for pressing against the mounting post 6. The other end of the elastic plate 42 is provided with a raised part 422. The raised part 422 is inclined and extends out of the mounting groove 71. The mounting cylinder 7 is provided with a threaded part 72 for threaded connection of the threaded cap 41. One end of the threaded cap 41 is provided with a part that abuts against the raised part 422 and is used to gradually push the raised part 422 into the mounting groove 71.
[0030] With the threaded engagement between the threaded cap 41 and the mounting cylinder 7, rotating the threaded cap 41 will cause it to move axially relative to the mounting cylinder 7. When the threaded cap 41 is completely disengaged from the raised portion 422 of the elastic plate 42, the elastic plate 42 will only lightly touch the mounting post 6. There will be only a slight friction between the pressure plate 421 on the elastic plate 42 and the mounting post 6. The operator can rotate the adjusting bracket 2 by applying a small force. When the threaded cap 41 approaches and pushes against the raised portion 422 of the elastic plate 42, the threaded cap 41 gradually pushes the raised portion 422... 2. Push it into the mounting groove 71. During this process, the elastic plate 42 is driven by its own elastic force to press the pressure plate 421 against the mounting column 6. The friction between the pressure plate 421 and the mounting column 6 increases continuously. That is, the frictional resistance when the adjusting frame 2 rotates can be adjusted by rotating the threaded cover 41 in conjunction with several elastic plates 42. The operator can adjust the magnitude of the friction when the adjusting frame 2 rotates as needed, so that the adjusting frame 2 can be adjusted to the designated position at any time and is not easy to deflect accidentally under the action of external force, which provides convenience for experimental operation.
[0031] Specifically, fastener 34 is a fastening bolt, slide 3 is movably sleeved on adjustment frame 2, fastening bolt is used to abut against adjustment frame 2, slide 3 is provided with threaded hole for fastening bolt thread installation, and fastening bolt is provided with a rotating handle.
[0032] The fastening bolt engages with the threaded hole. By rotating the handle, the fastening bolt can move closer to or further away from the adjusting frame 2. When it is necessary to move the slide 3, rotate the fastening bolt to drive it away from the adjusting frame 2, releasing the limit between the slide 3 and the adjusting frame 2, making it easy to move the slide 3. When it is necessary to fix the slide 3, rotate the fastening bolt to drive it closer to and abut against the adjusting frame 2, thus fixing the slide 3. This allows the operator to adjust the distance between the two slides 3 and their height position on the adjusting frame 2 as needed, adapting to the clamping of samples of various lengths, and also allowing adjustment of the height position of the clamped sample.
[0033] Example 3:
[0034] Reference Figures 1 to 6 In combination with the technical solutions of Embodiment 1 and Embodiment 2, in this embodiment, the pad 5 is provided with a slot 51, and the fixing plate 32 is provided with a plug 321 that is inserted and cooperates with the slot 51.
[0035] The pad 5 is detachably installed on the fixed plate 32 by means of plug-in connection, which makes it easy to replace the pad 5 of different thicknesses as needed to adjust the clamping force between the folding plate 31 and the pad 5, and facilitates experimental operation.
[0036] Specifically, the elastic element 33 is a torsion spring, which is located at the rotatable connection between the folding plate 31 and the slide block 3. The torsion spring acts on the folding plate 31 to drive one end of the folding plate 31 to elastically abut against the pad block 5.
[0037] The spring force of the torsion spring drives the folding plate 31 to elastically abut against the pad 5 to cooperate with the pad 5 to achieve the clamping work of the sample. The pad 5 of different thicknesses can be replaced as needed to adjust the clamping force between the folding plate 31 and the pad 5.
[0038] Specifically, both the pad 5 and the folding plate 31 are provided with textures 8 to increase friction.
[0039] By setting the texture 8 to increase friction, the sample can be effectively prevented from accidentally falling off the folding plate 31 and the pad 5.
[0040] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
