Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a large-area light reflectance difference compensation measuring instrument. Background Technology

[0002] The ratio of the radiant energy reflected from an object to the total radiant energy projected onto the object is called the reflectivity of that object. This applies to all wavelengths and should be called total reflectivity, or simply reflectivity.

[0003] According to the inspection institute, Chinese Patent Publication No. CN219625355U discloses a large-area light reflectivity difference compensation measuring instrument, which has the advantages of being easy to place the probe stably above the standard plate and the working ceramic plate, and being easy to operate.

[0004] However, when using the above technical solution, it is necessary to loosen two screws in sequence to adjust the height of the probe. After adjustment, it is necessary to tighten the two first screws to fix the position of the probe. At the same time, when disassembling and assembling the guide rod, the movable block must be removed first. This makes the assembly of the device and the adjustment of the probe height quite troublesome, thus reducing the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the background technology by proposing a large-area light reflectance difference compensation measuring instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A large-area optical reflectivity difference compensation measuring instrument includes:

[0008] The reflectivity meter body;

[0009] A hollow mounting base is fixedly installed on the top of the reflectivity measuring instrument body. A rotating disk is movably mounted on the top of the hollow mounting base. Multiple storage seats are fixedly installed on the top of the rotating disk. A drive motor for driving the rotating disk to rotate is fixedly installed inside the hollow mounting base.

[0010] The probe is mounted above the rotating disk via an adjustment assembly.

[0011] Preferably, the adjustment assembly includes a fixed block fixedly mounted on the outside of the reflectivity meter body. A retaining plate is detachably mounted on the fixed block, and a stud is fixedly mounted on the top of the retaining plate. A drive tube is threaded onto the surface of the stud, and two positioning rings are movably embedded in the surface of the drive tube. A connecting rod is fixedly mounted on the surface of each positioning ring, and the other end of the connecting rod is fixedly mounted on the surface of the probe. Limiting strips are fixedly mounted on opposite sides of the two connecting rods, and the limiting strips are slidably connected to the surface of the stud.

[0012] Preferably, the fixing block has an insertion hole on its side, which can be inserted into or separated from the card plate. A sliding rod that passes through the bottom of the insertion hole and penetrates the bottom of the card plate is inserted through the bottom of the insertion hole. A fixing plate is fixedly installed at the lower end of the rod. A spring is connected between the top of the fixing plate and the bottom of the fixing block.

[0013] Preferably, the surface of the drive tube has two symmetrically formed annular notches, and the two annular notches are slidably connected to two positioning rings respectively.

[0014] Preferably, a plurality of rubber particles are fixedly mounted on the surface of the drive tube.

[0015] Preferably, the surface of the stud has a limiting groove, and the limiting groove is slidably connected to both limiting strips.

[0016] Compared with existing technologies, the advantages of the large-area light reflectance difference compensation measuring instrument provided by this utility model are as follows:

[0017] 1. The user holds the drive tube and rotates it, causing the drive tube to move spirally up or down along the surface of the stud. This allows the probe to move vertically under the control of the limiting strip and the limiting groove, achieving the effect of rapid adjustment of the probe height. This solves the problem in traditional technology where two screws need to be loosened in sequence to adjust the probe height appropriately.

[0018] 2. By inserting the card plate and the fixing block, as well as the insertion rod and the card plate and the fixing block, the device can be quickly assembled, which improves the practicality of the device. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 4 A large-area light reflectance difference compensation measuring instrument, comprising:

[0026] The reflectance measuring instrument body 1; a hollow mounting base 2, fixedly installed on the top of the reflectance measuring instrument body 1, with a rotating disk 3 movably mounted on the top of the hollow mounting base 2. Multiple placement seats 4 are fixedly installed on the top of the rotating disk 3, and a drive motor 5 for driving the rotating disk 3 to rotate is fixedly installed inside the hollow mounting base 2; a probe 6, installed above the rotating disk 3 via an adjustment component. For the reflectance measurement of the standard plate and the working ceramic plate, please refer to the prior art document CN219625355U, which is existing publicly available technology, and will not be described in detail in this technical solution.

[0027] The adjustment assembly includes a fixed block 7 fixedly installed on the outside of the reflectivity measuring instrument body 1. A retaining plate 8 is detachably installed on the fixed block 7. An insertion hole 15 is provided on the side of the fixed block 7, and the insertion hole 15 can be inserted into or separated from the retaining plate 8. A rod 16 that slides through the bottom of the retaining plate 8 passes through the bottom of the insertion hole 15. A fixing plate is fixedly installed at the lower end of the rod 16. A spring 17 is connected between the top of the fixing plate and the bottom of the fixed block 7. When disassembling the stud 9, the fixing plate is pulled down, causing the rod 16 to move down and disengage from the retaining plate 8. Then, the retaining plate 8 is pulled outward, and the stud 9 can be quickly removed. When installing, the fixing plate is pulled down first, and then the retaining plate 8 is inserted into the insertion hole 15. Then, the fixing plate is released, and under the action of the spring 17, the rod 16 moves up quickly and inserts into the retaining plate 8, thus completing the installation and fixing of the stud 9, which facilitates the rapid assembly of the device.

[0028] A stud 9 is fixedly installed on the top of the card plate 8. A drive tube 10 is threaded onto the surface of the stud 9. Two positioning rings 11 are movably embedded on the surface of the drive tube 10. Two annular recesses 18 are symmetrically opened on the surface of the drive tube 10, and the two annular recesses 18 are slidably connected to the two positioning rings 11 respectively. By utilizing the slidable connection between the annular recesses 18 and the positioning rings 11, the positioning rings 11 can be moved and restricted within the annular recesses 18.

[0029] Each positioning ring 11 has a connecting rod 12 fixedly installed on its surface, and the other end of the connecting rod 12 is fixedly installed on the surface of the probe 6. Limiting strips 13 are fixedly installed on opposite sides of the two connecting rods 12, and the limiting strips 13 are slidably connected to the surface of the stud 9. The surface of the stud 9 has a limiting groove 14, and the limiting groove 14 is slidably connected to both limiting strips 13. By using the sliding engagement between the limiting strips 13 and the limiting grooves 14, it can be ensured that the positioning ring 11 and the probe 6 can only move vertically.

[0030] Furthermore, multiple rubber particles 19 are fixedly installed on the surface of the drive tube 10, which increases the frictional resistance between the user's hand and the surface of the drive tube 10 when the user rotates the drive tube 10, making it easier for the user to rotate the drive tube 10.

[0031] The working principle of this utility model is as follows:

[0032] When using the device, to adjust the height of the probe 6, the user holds the drive tube 10 and rotates it, causing the drive tube 10 to move spirally upward or downward along the surface of the stud 9. At this time, due to the sliding engagement of the limiting strip 13 and the limiting groove 14, it can be ensured that the probe 6 will not deflect when the drive tube 10 moves spirally. Thus, by using the limiting strip 13 and the limiting groove 14, the height of the probe 6 can be quickly adjusted.

[0033] Then, when disassembling the stud 9, pull the fixing plate down to make the insert rod 16 move down and disengage from the clamping plate 8. Then pull the clamping plate 8 outward to quickly remove the stud 9. When installing, first pull down the fixing plate, then insert the clamping plate 8 into the insertion hole 15, and then release the fixing plate. Then, under the action of the spring 17, the insert rod 16 quickly moves up and inserts into the clamping plate 8, thus completing the installation and fixing of the stud 9, which facilitates the rapid assembly of the device.

[0034] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
