Description

Technical Field

[0001] This utility model relates to the field of glass testing technology, specifically to a device for testing the light transmittance of plexiglass. Background Technology

[0002] Acrylic glass light transmittance testing devices are professional equipment used to accurately measure the light transmittance-related performance indicators of acrylic glass. Common types include light transmittance testers, spectrophotometers, and haze meters, which are used to measure the light transmittance of acrylic glass, that is, the percentage of light flux transmitted through the acrylic glass to the incident light flux.

[0003] Existing glass transmittance testers only measure the glass plane, not the cross-section. However, the internal structure of glass may vary in different directions. Measuring only the planar transmittance fails to reveal how light propagates along the cross-section, thus not comprehensively reflecting the anisotropy of the glass's optical properties. Furthermore, internal defects such as bubbles, impurities, and cracks may affect the transmittance of the plane and cross-section to different degrees. Some defects may be overlooked during planar testing, but their scattering and absorption effects on light may be more pronounced in the cross-section. Additionally, for specially treated glass, such as surface coatings or internal doping, measuring only the planar transmittance cannot accurately assess the effects of these treatments on light in different directions.

[0004] Therefore, it is necessary to invent a device for testing the light transmittance of plexiglass to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the light transmittance of plexiglass, in order to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for testing the light transmittance of plexiglass, comprising a base, wherein support frames are vertically fixedly installed on both sides of the upper end of the base, and a crossbeam is provided on the top of the two support frames, and a sample holder is provided on the upper surface of the base and between the two support frames.

[0007] A detection probe is fixedly installed at the bottom center of the crossbeam, and electric push rods are fixedly installed at both ends of the top of the crossbeam. The output ends of the two electric push rods penetrate through the bottom of the crossbeam.

[0008] The two support frames are provided with symmetrical screws in opposite directions. Each screw has a washer fixedly installed at its front end. The front of the washer is serrated and made of rubber material.

[0009] As a preferred embodiment of this utility model, a contact slot is provided on the upper surface of the base, and a contact connector is fixedly installed at the bottom of the sample holder. The contact connector is adapted to the contact slot for insertion and connection.

[0010] As a preferred embodiment of this utility model, the upper surface of the sample holder is provided with a clamping groove, and a lamp tube is embedded in the bottom of the clamping groove. The sample holder is located directly below the detection probe and the electric push rod.

[0011] As a preferred embodiment of this utility model, both of the support frames have through holes at their top ends, and support columns are fixedly installed at the bottom of both ends of the crossbeam. The support columns are adapted to the through holes and are vertically inserted into the through holes. The length of the support column is greater than the height of the base.

[0012] As a preferred embodiment of this utility model, both of the support frames have symmetrical through-hole threaded holes on their sides, the screw is threadedly connected to the corresponding threaded hole, and the two gaskets are located at the two ends directly above the sample holder.

[0013] As a preferred embodiment of this utility model, the front of the base is provided with a display screen and control buttons, and the internal control components of the base are electrically connected to the detection probe, electric push rod, etc. via wires.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The sample holder design enables the detection of light transmittance across the cross-section of acrylic glass. This allows for the acquisition of light propagation along the glass's cross-section, comprehensively reflecting the anisotropy of the glass's optical properties, filling a gap in existing testing methods, and more accurately evaluating the optical characteristics of the glass.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-5 The device for testing the light transmittance of plexiglass shown includes a base 1, with support frames 2 vertically fixed on both sides of the upper end of the base 1, a crossbeam 3 on the top of the two support frames 2, and a sample holder 4 on the upper surface of the base 1 and located between the two support frames 2.

[0026] A detection probe 33 is fixedly installed at the bottom center of the crossbeam 3, and electric push rods 32 are fixedly installed at both ends of the top of the crossbeam 3. The output ends of the two electric push rods 32 pass through the bottom of the crossbeam 3.

[0027] Two support frames 2 are provided with symmetrical screws 23 in opposite directions. Each screw 23 has a washer 24 fixedly installed at its front end. The front of the washer 24 is serrated and made of rubber material.

[0028] In this example, since the size of the clamping groove 41 is not suitable for all glass samples of different sizes, the electric push rod 32, through the up-and-down movement of its output end, can abut against the glass sample placed vertically in the clamping groove 41 of the sample holder 4, thereby playing a certain role in clamping and fixing it, and can be flexibly adjusted according to the thickness of the acrylic sample. The detection probe 33, as the core detection component, accurately detects information such as the light intensity after light passes through the acrylic glass, and calculates the transmittance through an internal algorithm, providing key data for evaluating the light transmittance performance of the acrylic glass.

[0029] Furthermore, in the above technical solution, a contact slot 11 is provided on the upper surface of the base 1, and a contact connector 42 is fixedly installed on the bottom of the sample holder 4. The contact connector 42 is adapted to the contact slot 11 for insertion and connection.

[0030] In this example, by adapting and connecting the contact slot 11 on the upper surface of the base 1 with the contact connector 42 at the bottom of the sample holder 4, the sample holder 4 can be quickly installed and disassembled, making it convenient to replace different samples for testing; at the same time, a stable electrical connection is achieved to power the lamp tube and other components on the sample holder 4, ensuring the normal operation of the auxiliary lighting function.

[0031] Furthermore, in the above technical solution, a clamping groove 41 is provided on the upper surface of the sample holder 4, and a lamp tube is embedded in the bottom of the clamping groove 41. The sample holder 4 is located directly below the detection probe 33 and the electric push rod 32.

[0032] Furthermore, in the above technical solution, the top of each of the two support frames 2 is provided with a through hole 21, and the bottom of both ends of the crossbeam 3 are fixedly installed with support columns 31. The support columns 31 are adapted to the through holes 21, and the support columns 31 are vertically inserted into the through holes 21. The length of the support column 31 is greater than the height of the base 1.

[0033] In this example, the through holes 21 on the support frame 2 are adapted to the support columns 31 at both ends of the crossbeam 3, allowing the crossbeam 3 to be stably installed on top of the support frame 2, ensuring the stability of the entire device structure and providing reliable support for components such as the detection probe 33. Furthermore, this structural design allows the crossbeam 3 to be quickly disassembled and installed from the support frame 2, and the support columns 31 also serve to support the crossbeam 3. Therefore, when inspecting the plane of the glass, the crossbeam 3 is disassembled, simultaneously moving the detection probe 33 and the electric push rod 32, thus placing the crossbeam 3 above the sample holder 4, so that the crossbeam 3 and the sample holder 4 are arranged in a cross shape. This allows the detection probe 33 below the crossbeam 3 to detect the light transmittance of the horizontally placed glass plane on the sample holder 4.

[0034] Furthermore, in the above technical solution, both support frames 2 have symmetrical through-hole threaded holes 22 on their sides, the screw 23 is threadedly connected to the corresponding threaded hole 22, and the two gaskets 24 are located at the two ends directly above the sample holder 4.

[0035] In this example, the threaded hole 22, screw 23, and washer 24 are combined. The threaded hole 22 and screw 23 are threadedly connected. Rotating the screw 23 can push the serrated rubber washer 24 at the front end to move towards the sample holder 4. The serrated design increases friction and can firmly clamp the vertically placed glass sample; the rubber material avoids damage to the sample, ensuring that the acrylic sample is stably fixed during the test and preventing deviations in the test results due to sample movement.

[0036] Furthermore, in the above technical solution, the front of the base 1 is provided with a display screen and control buttons, and the internal control components of the base 1 are electrically connected to the detection probe 33, electric push rod 32, etc. via wires.

[0037] In this example, the display screen and control buttons are located on the front of the base 1. The display screen intuitively shows data such as the light transmittance of the plexiglass measured by the detection probe 33, allowing operators to obtain test results in real time without complex conversions or calculations. The control buttons allow operators to start / stop the detection, set detection parameters such as sensitivity, and control the raising and lowering of the electric push rod 32, enabling human-machine interaction, making the device operation more convenient and user-friendly, and improving detection efficiency.

[0038] The working process of the acrylic glass light transmittance testing device provided by this utility model is as follows:

[0039] Testing the cross-sectional transmittance: Place the acrylic sample vertically in the clamping groove 41 of the sample holder 4, with the side cross-section of the sample facing upwards and the bottom surface in contact with the bottom of the clamping groove 41 at the upper end of the sample holder 4. Rotate the screw 23 on the side of the support frame 2, which pushes the serrated rubber pad 24 towards the sample through the threaded hole 22 until the pad 24 clamps both sides of the sample, ensuring the sample is stable and does not damage the surface.

[0040] To test the transmittance of the plane, the crossbeam 3 needs to be disassembled and the structure adjusted: First, pull the support columns 31 at both ends of the crossbeam 3 out of the through holes 21 at the top of the support frame 2, and disassemble the crossbeam 3. Place the crossbeam 3 horizontally above the sample holder 4, so that the crossbeam 3 and the sample holder 4 are arranged in a cross shape, and align the detection probe 33 with the sample plane. Place the plexiglass sample horizontally above the sample holder 4. When not clamping the plane with screws 23, the sample can usually be placed horizontally.

[0041] If the two screws 23 can effectively clamp and fix the vertically placed glass sample using the two opposite washers 24, then the detection probe 33 can be installed at the bottom of the output end of the two electric push rods 32. Then, the electric push rods 32 can be started by the control button on the front of the base 1, driving the detection probe 33 to move up and down. The distance between the probe and the sample cross-section can be adjusted according to the sample thickness, usually close to the sample surface or maintaining a fixed detection distance. This eliminates the resistance of the electric push rods 32 to the top of the glass sample, increasing its practicality.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
