Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixture technology, specifically a fixture for rapid testing of the retroreflection coefficient of reflective coatings. Background Technology
[0002] The fixture for rapid testing of retroreflective coefficient of reflective coatings is a device used to clamp and install samples in the rapid testing of retroreflective coefficient of reflective coatings.
[0003] Based on the above, the inventors have discovered that: Currently, there are many rapid tests for the retroreflection coefficient of reflective coatings on the market. However, in general, rapid tests for the retroreflection coefficient of reflective coatings involve the operator holding the sample and placing it under the testing instrument. However, even slight shaking by the operator can easily cause the sample to vibrate, thus affecting the accuracy of the testing instrument's measurement. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a fixture for rapid testing of the retroreflection coefficient of reflective coatings, aiming to achieve a more practical purpose. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model discloses a fixture for rapid testing of the retroreflection coefficient of reflective coatings, comprising a base plate, a pad fixed to the top of the base plate, a sample placed on the top of the pad, a clamping mechanism on the outer wall of the sample, and a limiting mechanism on the outer wall of the clamping mechanism.
[0006] The clamping mechanism includes:
[0007] Four clamping plates are provided, each located at the bottom of the sample. A slider is fixed to the bottom of each of the four clamping plates. Two iron pillars slide on the inner wall of each slider, and the outer walls of the two iron pillars are fixed to the inner wall of the base plate.
[0008] As a preferred embodiment of this utility model, the outer wall of the base plate has two limiting blocks that slide, and both limiting blocks are disposed on the outer wall of the sample.
[0009] As a preferred embodiment of this utility model, each of the four clamping plates has a connecting plate at its top end, and each of the four connecting plates has a pressure plate fixed at its bottom end. The four pressure plates are all located at the top of the sample.
[0010] As a preferred embodiment of this utility model, the inner walls of the four connecting plates are threaded with studs, and the bottom ends of the four studs are threaded with the inner walls of the clamping plates.
[0011] As a preferred embodiment of this utility model, the limiting mechanism includes:
[0012] Four magnets are located at the top of an iron column. Each of the four magnets has a connecting column fixed to its top. Each of the four connecting columns has a sliding ring plate on its outer wall. One side of each of the four ring plates is fixed to the outer wall of a clamping plate.
[0013] As a preferred embodiment of this utility model, the inner walls of the four connecting columns are provided with recesses, and the four recesses are all located on the outer wall of the ring plate.
[0014] As a preferred embodiment of this utility model, two limiting posts are fixed to the outer walls of the two limiting blocks, and one end of each of the four limiting posts is matched with the inner wall of the base plate.
[0015] The beneficial effects of this utility model are:
[0016] 1. In this scheme, the sample is placed on top of the pad, and two limiting blocks slide on the outer wall of the base plate until the outer walls of the two limiting blocks abut against the outer wall of the sample. At the same time, the outer wall of the limiting post fixed to the outer wall of the limiting blocks engages with the inner wall of the base plate, thus limiting and fixing the sample in front and behind the pad. A clamp slides on the outer wall of the base plate, causing the slider fixed at the bottom of the clamp to slide on the inner wall of the base plate. At the same time, the inner wall of the slider slides with the outer wall of the iron column fixed to the inner wall of the base plate until the outer wall of the clamp abuts against the bottom of the sample. The outer wall of the connecting column fits into the inner wall of the ring plate, so that the magnet fixed at the bottom of the connecting column magnetically attracts the top of the iron column, thereby strengthening the stability of the sample installed on top of the pad and preventing the sample from shaking on top of the pad due to external interference, thus making the device more stable in clamping and installing the sample.
[0017] 2. In this solution, the connecting plate slides on the outer wall of the clamping plate, so that the bottom end of the pressure plate fixed on the outer wall of the connecting plate fits against the top end of the sample. The outer wall of the stud is threaded with the inner wall of the connecting plate until the bottom end of the stud is threaded with the inner wall of the clamping plate. This combination of the pressure plate and the clamping plate secures the sample to the top of the pad. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example: Figures 1-5 As shown, this utility model provides a fixture for rapid testing of the retroreflection coefficient of reflective coatings, including a base plate 1, a pad 2 fixed to the top of the base plate 1, a sample 3 provided at the top of the pad 2, a clamping mechanism 4 provided on the outer wall of the sample 3, and a limiting mechanism 5 provided on the outer wall of the clamping mechanism 4.
[0027] Clamping mechanism 4 includes:
[0028] Four clamping plates 41 are provided at the bottom of the sample 3. Each clamping plate 41 has a slider 42 fixed at its bottom. Two iron pillars 43 slide on the inner wall of each slider 42. The outer walls of the two iron pillars 43 are fixed to the inner wall of the base plate 1. Each clamping plate 41 has a connecting plate 44 at its top. Each connecting plate 44 has a pressure plate 45 fixed at its bottom. Each pressure plate 45 is provided at the top of the sample 3. Each connecting plate 44 has a stud 46 threaded on its inner wall. The bottom of each stud 46 is threaded to the inner wall of the clamping plate 41.
[0029] As attached Figure 1 and Figure 2 As shown, two limiting blocks 6 slide on the outer wall of the base plate 1. Both limiting blocks 6 are set on the outer wall of the sample 3. Two limiting posts 7 are fixed on the outer wall of each of the two limiting blocks 6. One end of each of the four limiting posts 7 is matched with the inner wall of the base plate 1 to facilitate the normal use of the device.
[0030] As attached Figure 1, Figure 3 , Figure 4 and Figure 5 As shown, the limiting mechanism 5 includes:
[0031] Four magnets 51 are all located at the top of the iron column 43. Each of the four magnets 51 has a connecting column 52 fixed at its top. Each of the four connecting columns 52 has a sliding ring plate 53 on its outer wall. One side of each of the four ring plates 53 is fixed to the outer wall of the clamping plate 41. Each of the four connecting columns 52 has a recess 54 on its inner wall. Each of the four recesses 54 is located on the outer wall of the ring plate 53. This strengthens the stability of the sample 3 installed at the top of the pad 2 and prevents the sample 3 from shaking at the top of the pad 2 due to external interference.
[0032] Working principle: In use, place sample 3 on top of pad 2. Use two limiting blocks 6 to slide on the outer wall of base plate 1 until the outer walls of the two limiting blocks 6 abut against the outer wall of sample 3. At the same time, the outer wall of the limiting post 7 fixed to the outer wall of the limiting block 6 engages with the inner wall of base plate 1, thus limiting and fixing sample 3 in front and behind pad 2. Use clamp 41 to slide on the outer wall of base plate 1, causing the slider 42 fixed at the bottom of clamp 41 to slide on the inner wall of base plate 1. At the same time, the inner wall of slider 42 slides against the outer wall of iron post 43 fixed to the inner wall of base plate 1 until the outer wall of clamp 41 abuts against the bottom of sample 3. Use the outer wall of connecting post 52 and ring plate 5 The inner wall of the 3 is fitted so that the magnet 51 fixed at the bottom of the connecting column 52 is magnetically attracted to the top of the iron column 43, thereby strengthening the stability of the sample 3 installed on the top of the pad 2 and preventing the sample 3 from shaking on the top of the pad 2 due to external interference. This makes the device more stable in clamping and installing the sample 3. The connecting plate 44 slides on the outer wall of the clamping plate 41 so that the bottom of the pressure plate 45 fixed on the outer wall of the connecting plate 44 fits against the top of the sample 3. The outer wall of the stud 46 is threaded with the inner wall of the connecting plate 44 until the bottom of the stud 46 is threaded with the inner wall of the clamping plate 41. Under the combination of the pressure plate 45 and the clamping plate 41, the sample 3 is firmly installed on the top of the pad 2.
