Description

Technical Field

[0001] This application relates to the field of flatness testing, and more specifically, to a flatness testing device. Background Technology

[0002] In the process of decoration and renovation, tools for testing the flatness of a surface are frequently used. Most existing flatness testing devices use a spirit level to test the surface. The spirit level directly displays the angular displacement and measures the degree of deviation of the measured surface from its horizontal, vertical, and tilt positions.

[0003] Existing flatness testing devices mostly rely on manual leveling for calibration, which leads to data deviations caused by device tilting during the testing process. Furthermore, the detection of deviations is delayed, requiring repeated adjustments and calibrations, resulting in low efficiency. Traditional contact testing methods, such as straightedges and feeler gauges, require direct contact with the wall surface for measurement, which is not only cumbersome and time-consuming but also susceptible to human error, making it difficult to intuitively reflect the flatness deviation values. Therefore, a flatness testing device is needed to help solve this problem. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a flatness testing device. This addresses the problem that existing flatness testing devices often rely on manual leveling, leading to data deviations caused by device tilting during testing. Furthermore, deviations are often delayed in detection, requiring repeated adjustments and calibrations, resulting in low efficiency. Traditional contact testing methods, such as straightedges and feeler gauges, require direct contact with the wall surface for measurement, which is not only cumbersome and time-consuming but also susceptible to human error, making it difficult to intuitively reflect the flatness deviation values.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A flatness testing device includes: a first mounting plate and a second mounting plate. A plug rod is vertically fixed at the top of the first mounting plate, and the plug rod is installed through the second mounting plate. Plug plates are symmetrically and vertically fixed at the top of the first mounting plate. Through slots are symmetrically formed on both sides of the second mounting plate, and the plug plates are installed through the through slots. A handle is fixed on the inner side of the second mounting plate. A protruding plate is provided on the side of the second mounting plate above the handle, and a bubble meter is embedded in the protruding plate. A receiving cavity is formed near the top of the second mounting plate, and a horizontal plate is hinged to the receiving cavity. A laser is hinged to the end of the horizontal plate away from the second mounting plate. A mounting cavity is formed near the bottom of the first mounting plate, and a horizontal plate is hinged to the mounting cavity. A scale plate is embedded at the top of the horizontal plate. The laser and the scale plate work together to determine the flatness of the cavity wall.

[0008] Furthermore, a positioning hole is provided at the hinge end of the horizontal plate, and a fixing component for assisting in fixing the horizontal plate is installed on the outer side of the second mounting plate.

[0009] Furthermore, the fixing assembly includes a fixing cylinder fixed to the outer side of the second mounting plate. The fixing cylinder has a compression chamber inside, a pin is slidably disposed in the compression chamber, and a pressure spring for assisting the pin to press is installed in the compression chamber. The pin is engaged with the positioning hole, and a connecting rod is fixed to one end of the pin. The connecting rod extends through the fixing cylinder.

[0010] Furthermore, the end of the pin that extends into the positioning hole has a rectangular block structure.

[0011] Furthermore, limit strips are symmetrically and vertically fixed on both sides of the plug plate, and limit grooves are symmetrically opened on both sides of the through groove, with the limit strips and the limit grooves engaging with each other.

[0012] Furthermore, a positioning bolt is threaded onto the outer side of the plug plate, and one end of the positioning bolt presses against the inner side of the through groove.

[0013] Furthermore, an adsorption plate is embedded in the top of the horizontal plate and the mounting cavity, and the two adsorption plates work together to adsorb each other.

[0014] The beneficial effects of this application are as follows: the embedded installation design of the bubble meter allows the inspector to monitor the horizontal status of the device in real time, avoiding the deviation of the test data caused by the tilt of the device and improving the accuracy of the test. The use of the laser meter and the scale plate together realizes non-contact flatness test. The flatness deviation of the wall surface is intuitively displayed by the landing point of the laser beam on the scale plate. The test efficiency is high and the results are intuitive.

[0015] The horizontal plate is quickly fixed by inserting a pin into the positioning hole through a top pressure spring using a fixed component. The operation is simple and the fixation is stable, avoiding accidental flipping of the horizontal plate during the testing process and affecting the test results. Attached Figure Description

[0025] The following is a detailed description of a flatness detection device provided in this application, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this application.

[0026] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0027] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0028] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-4 As shown, this utility model provides a flatness detection device, comprising a first mounting plate 1 and a second mounting plate 2. A plug-in rod 3 is vertically fixed at the top of the first mounting plate 1 and is installed through the second mounting plate 2. A plug-in plate 4 is symmetrically and vertically fixed at the top of the first mounting plate 1. Through slots 5 are symmetrically opened on both sides of the second mounting plate 2, and the plug-in plate 4 is installed through the through slots 5. Limiting strips 41 are symmetrically and vertically fixed on both sides of the plug-in plate 4. Limiting grooves 51 are symmetrically opened on both sides of the through slots 5. The limiting strips 41 and the limiting grooves 51 are fitted together. A positioning bolt 42 is threaded on the outer side of the plug-in plate 4, and one end of the positioning bolt 42 presses against the inner side of the through slot 5.

[0030] The dual guiding structure of the plug rod 3 and the plug plate 4, combined with the plugging design of the limiting strip 41 and the limiting groove 51, effectively improves the guiding accuracy of the second mounting plate 2 during sliding adjustment, reduces the shaking error during the detection process, and the top pressing fixing method of the positioning bolt 42 can quickly lock the position of the second mounting plate 2. The operation is convenient and the fixing is reliable, which can adapt to the detection needs of walls of different heights.

[0031] A handle 6 is fixed on the inner side of the second mounting plate 2. A protruding plate is provided above the handle 6 on the side of the second mounting plate 2. A bubble meter 7 is embedded in the protruding plate. A receiving cavity 8 is opened near the top of the second mounting plate 2. A horizontal plate 9 is hinged to the receiving cavity 8. A laser meter 10 is hinged to the end of the horizontal plate 9 away from the second mounting plate 2. An installation cavity is opened near the bottom of the first mounting plate 1. A horizontal plate 11 is hinged to the installation cavity. A scale plate 12 is embedded in the top of the horizontal plate 11. The laser meter 10 and the scale plate 12 cooperate to determine the flatness of the cavity wall. Adsorption plates 13 are embedded in the top of the horizontal plate 11 and the installation cavity. The two adsorption plates 13 cooperate to adsorb each other.

[0032] The embedded installation design of the bubble meter 7 allows inspectors to monitor the horizontal status of the device in real time, avoiding data deviation caused by device tilt and improving inspection accuracy. The combined use of the laser meter 10 and the scale plate 12 enables non-contact flatness inspection. The flatness deviation of the wall surface is intuitively displayed by the position of the laser beam landing on the scale plate 12, resulting in high inspection efficiency and intuitive results.

[0033] The horizontal plate 9 has a positioning hole 91 at the hinge end. The second mounting plate 2 has a fixing component 14 for fixing the horizontal plate 9. The fixing component 14 includes a fixing cylinder 15 fixed on the outer side of the second mounting plate 2. The fixing cylinder 15 has a compression chamber. A pin 18 is slidably disposed in the compression chamber. A pressing spring 16 for pressing the pin 18 is installed in the compression chamber. The pin 18 is engaged with the positioning hole 91. A connecting rod 17 is fixed to one end of the pin 18. The connecting rod 17 extends through the fixing cylinder 15. The end of the pin 18 that extends into the positioning hole 91 has a rectangular block structure.

[0034] The horizontal plate 9 is quickly fixed by the fixed component 14, which drives the pin 18 to be inserted into the positioning hole 91 through the top pressure spring 16. The operation is simple and the fixation is stable, avoiding the horizontal plate 9 from accidentally flipping over during the test and affecting the test results.

[0035] Working principle: When using this flatness testing device, the first mounting plate 1 is attached to the bottom of the wall surface to be tested, and the second mounting plate 2 is installed through the plug rod 3 and slides along it. At the same time, the plug plate 4 is inserted into the through grooves 5 on both sides of the second mounting plate 2. The sliding guide stability is ensured by the plugging and cooperation of the limiting strip 41 and the limiting groove 51. The positioning bolt 42 presses against the inner side of the through groove 5 to fix the second mounting plate 2. After adjusting to the required testing height.

[0036] The bubble level 7 is embedded in the protruding plate on the side of the second mounting plate 2. The position of the bubble indicates whether the entire device is level, ensuring accurate detection. When wall flatness needs to be detected, the horizontal plate 9 inside the cavity 8 of the second mounting plate 2 is rotated 90 degrees. The pin 18 is inserted into the positioning hole 91 of the horizontal plate 9 by the top pressure spring 16 in the fixing cylinder 15 of the fixing assembly 14. At this time, the laser instrument 10 at the end of the horizontal plate 9 emits a laser beam. Simultaneously, the horizontal plate 11 inside the mounting cavity of the first mounting plate 1 unfolds, and the scale plate 12 on its top cooperates with the laser beam of the laser instrument 10. The wall flatness deviation is determined by the position of the laser beam landing on the scale plate 12. The horizontal plate 11 and the adsorption plate 13 at the mounting cavity are fixed after unfolding by magnetic adsorption, ensuring the stability of the scale plate 12 during the detection process.
