Description

Technical Field

[0001] This utility model relates to the field of caulking compound construction technology, specifically a caulking compound construction degree measuring instrument. Background Technology

[0002] Joint sealant is a sealing material used in building construction to fill structural gaps (such as walls, roofs, and roads). Its workability (i.e., the fluidity of the material under specific conditions) is a key indicator for measuring its workability. If the workability is too low (poor fluidity), it will lead to difficulties in filling the gaps and failure to fully fill them. If the workability is too high (excessive fluidity), it may cause adverse effects such as dripping and deformation after construction, thus affecting the sealing effect and project quality. Therefore, workability measurement is a core testing item for joint sealant production quality control, project material selection, and construction acceptance.

[0003] Traditional instruments are typically operated manually. Operators must manually adjust the height of the cone, release it, and use a stopwatch to time the depth of penetration, then read the depth using a ruler. This method can lead to inconsistencies in the measured height or timing, resulting in errors. Furthermore, traditional instruments require an external temperature chamber to heat the sample container before testing. During testing, the temperature drops, causing measurement deviations and significantly reducing the accuracy and consistency of measurements. This makes them quite inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a sealant application degree tester to solve the problem mentioned in the background art where the temperature of the sample container drops during measurement, affecting the test results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealant application degree measuring instrument, comprising a control base, a column inserted and installed on the outer surface of the control base, a drive motor fixedly installed inside the control base, and a second gear fixedly installed at the output end of the drive motor, a tray rotatably installed inside the control base, a circular groove formed on the outer surface of the control base, the circular groove of the control base being concentrically designed with the sample container, a fan fixedly installed at the end of the control base away from the column, a heating element fixedly installed inside the control base, a temperature sensor fixedly installed inside the control base, and an air duct formed inside the control base, the air duct of the control base connecting the fan, heating element, and temperature sensor in series.

[0006] Preferably, a retaining ring is fitted onto the outer surface of the circular groove of the control base, and the retaining ring and the tray are concentrically designed, with the outer surface of the retaining ring fitting against the outer surface of the sample container.

[0007] By adopting the above technical solution, the sample container can be blocked and limited by the retaining ring, so that the gap between the retaining ring and the sample container can be eliminated, and the hot air passing through the air duct will not leak, so as to fully heat the sample container.

[0008] Preferably, a slip ring is fixedly installed on the outer surface of the rotating shaft of the tray, and a first electromagnet is fixedly installed on the outer surface of the end of the tray near the retaining ring, and the outer surface of the first electromagnet is in contact with the outer surface of the sample container.

[0009] By adopting the above technical solution, the first electromagnet can also be energized when the tray rotates through the slip ring, so that the first electromagnet can firmly attract the sample container. When the tray drives the sample container to rotate, the sample container will not get stuck and unable to rotate. Furthermore, the uniformity of hot air heating can be further improved by the tray driving the sample container to rotate.

[0010] Preferably, a first gear is fixedly mounted on the outer surface of the tray, and the first gear meshes with a second gear, and the diameter of the second gear is smaller than the diameter of the first gear.

[0011] By adopting the above technical solution, the second gear can be driven by the drive motor to rotate, and the first gear meshing with the second gear can follow the rotation, thereby driving the tray to rotate. This allows the sample container that has been tested to rotate to the untested area and maintain concentricity, so that the cone will fall at the same distance during the next test, thus improving the accuracy of the data obtained during the test.

[0012] Preferably, the outer surface of the column is uniformly provided with scale lines, and a limit block is slidably installed on the outer surface of the column, and the screws on the outer surface of the limit block are in contact with the outer surface of the column.

[0013] By adopting the above technical solution, the limit block can be quickly moved to the required height and locked by the scale line of the column, which improves the convenience of fixing the limit block and restricts the position of the moving block by the limit block, so that the moving block can be quickly moved to the set height during multiple measurements, which greatly reduces the error caused by different heights during measurement.

[0014] Preferably, a second electromagnet is fixed to one end of the column and facing forward. A movable block is slidably installed on the outer surface of the column, and the side surface of the movable block is in contact with the outer surface of the second electromagnet. A plug-in rod is fixedly installed on the outer surface of the movable block near the retaining ring, and a fixing rod is slidably installed on the outer surface of the plug-in rod. A cone is fixed on the outer surface of the fixing rod, and the outer surface of the fixing rod is in contact with the outer surface of the cone.

[0015] By employing the above technical solution, the moving block is attracted by the second electromagnet. After the moving block reaches the set location, it can be attracted and fixed. When measuring, the second electromagnet is de-energized, which can effectively reduce the error caused by hand shaking or force. At the same time, the cone can be easily fixed to one end of the fixing rod, and after the measurement is completed, the fixing rod can be easily removed from the plug rod, which facilitates the cleaning of residual grease on the outer surface of the cone. After cleaning, the plug rod can be inserted back and maintained at the original height, which greatly improves the convenience of cleaning and reduces the error caused by hand operation during measurement.

[0016] Preferably, elastic buckles are fixedly installed on both outer surfaces of the fixing rod, and the elastic buckles engage with the plug rod. A grating ruler assembly is fixedly installed at the end of the column away from the fixing rod, and the other end of the grating ruler assembly is connected to the moving block.

[0017] Using the above technical solution, the distance between the fixed rod and the plug rod can be adjusted by the elastic buckle to adjust the position and distance of the cone above the sample container, so as to obtain test results at different positions. The falling distance of the moving block can be recorded by the grating ruler assembly, so that the control base can accurately record the falling distance of the moving block within a set time. When the time is up, the grating ruler assembly automatically records the unknown, which greatly improves the accuracy of the falling distance during measurement.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the sealant workability measuring instrument:

[0019] 1. When using this product, simply fill the sample container with the grease and place it inside the control base, ensuring the retaining ring seals the gap between the grease and the sample container. Then, adjust the heating temperature of the heating element through the control base and start the fan to inject air into the control base. This allows the air to be heated and sent into the air duct of the control base. The temperature sensor monitors and controls the opening and closing of the heating element. Together with the tray, this rotates the sample container to heat it evenly and maintain the temperature of the sample container and grease during subsequent measurements, reducing measurement errors caused by temperature drops.

[0020] 2. Once the sample container is placed inside the control base, the first electromagnet can be activated. The sample container is fixed by the attraction of the first electromagnet, which enables the drive motor to drive the second gear to rotate. The first gear, which meshes with the second gear, rotates together, allowing the tray to rotate and driving the sample container to rotate. After the cone is inserted into the grease and the measurement is completed, the measurement position of the sample container can be changed by rotating the tray without moving the cone, which greatly improves the accuracy and convenience of data when performing multiple measurements.

[0021] 3. The limit block can be quickly moved to the required height by the scale lines on the outer surface of the column. Then, the position of the fixing rod on the plug rod can be adjusted by the elastic buckle, so that the distance between the cone and the sample container can be adjusted to limit and adjust the height of the moving block. This ensures that the cone is at the same height during multiple measurements by limiting the limit block, thereby improving the accuracy of the data obtained in subsequent measurements.

[0022] 4. By using the attraction of the second electromagnet, the moving block can be attracted and fixed after reaching the measurement position. During measurement, the moving block can fall naturally when the second electromagnet is de-energized, and the grating ruler assembly records the data after the second electromagnet is de-energized. This greatly increases the distance the cone penetrates into the grease during measurement, further improving the accuracy of the measurement and eliminating errors caused by manual operation.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a caulking compound application degree tester, including a control base 1, a column 12 inserted and installed on the outer surface of the control base 1, a drive motor 2 fixedly installed inside the control base 1, and a second gear 7 fixedly installed at the output end of the drive motor 2, a tray 3 rotatably installed inside the control base 1, a circular groove opened on the outer surface of the control base 1, and the circular groove of the control base 1 is concentrically designed with the sample container, a retaining ring 8 is engaged and installed on the outer surface of the circular groove of the control base 1, and the retaining ring 8 is concentrically designed with the tray 3, and a first gear 6 is fixedly installed on the outer surface of the tray 3, and the first gear 6 meshes with the second gear 7. The second gear 7 has a smaller diameter than the first gear 6. A slip ring 4 is fixedly installed on the outer surface of the rotating shaft of the tray 3. A first electromagnet 5 is fixedly installed on the outer surface of the tray 3 near the retaining ring 8, and the outer surface of the first electromagnet 5 is in contact with the outer surface of the sample container. The outer surface of the retaining ring 8 is in contact with the outer surface of the sample container. A fan 9 is fixedly installed on the end of the control base 1 away from the column 12. A heating element 10 is fixedly installed inside the control base 1. A temperature sensor 11 is fixedly installed inside the control base 1. An air duct is opened inside the control base 1, and the air duct of the control base 1 connects the fan 9, the heating element 10, and the temperature sensor 11 in series.

[0032] First, the sludge needs to be filled into the sample container and placed inside the control base 1, so that the sample container can contact the outer surface of the retaining ring 8 and the first electromagnet 5. Then, the temperature of the heating element 10 can be adjusted by the control base 1 and the fan 9 can be turned on to send air into the control base 1 and heat it through the heating element 10. Then, the temperature of the hot air is monitored by the temperature sensor 11. Once the temperature reaches the set value, the heating element 10 can be automatically turned off. The sample container can be rotated by the rotation of the tray 3, and the first electromagnet 5 can be energized and attracted by the slip ring 4 to heat the sample container evenly and keep the sample container at a constant temperature. This prevents measurement errors caused by temperature drop during subsequent measurements and greatly reduces the data error of the measuring instrument caused by temperature drop.

[0033] The outer surface of the column 12 is evenly marked with scale lines, and a limit block 13 is slidably installed on the outer surface of the column 12. The screws on the outer surface of the limit block 13 are in contact with the outer surface of the column 12. A second electromagnet 15 is fixed forward on one side surface of the column 12. A moving block 14 is slidably installed on the outer surface of the column 12, and the side surface of the moving block 14 is in contact with the outer surface of the second electromagnet 15. A plug-in rod 18 is fixedly installed on the outer surface of the moving block 14 near the retaining ring 8, and a fixing rod 17 is slidably installed on the outer surface of the plug-in rod 18. A cone is fixed on the outer surface of the fixing rod 17, and the outer surface of the fixing rod 17 is in contact with the outer surface of the cone.

[0034] Secondly, the position of the limiting block 13 on the column 12 can be adjusted and fixed by the scale lines on the outer surface of the column 12 to limit the moving height of the moving block 14. Then, the distance between the fixing rod 17 and the plug rod 18 can be adjusted, and the cone can be fixed on the outer surface of the fixing rod 17 so that the moving block 14 can quickly reach the limited height during measurement. Then, the moving block 14 is attracted and fixed by the second electromagnet 15. After that, the second electromagnet 15 is de-energized, so that the cone on the moving block 14 can automatically fall and insert into the grease in the sample container. During the falling process, the falling distance is recorded by the grating ruler assembly 16, which greatly improves the convenience and accuracy of measurement and reduces the error generated by the measuring instrument.

[0035] The outer surfaces of both sides of the fixed rod 17 are fixedly equipped with elastic buckles 19, and the elastic buckles 19 are engaged with the plug rod 18. The end of the column 12 away from the fixed rod 17 is fixedly equipped with a grating ruler assembly 16, and the other end of the grating ruler assembly 16 is connected to the moving block 14.

[0036] After the first measurement is completed, the moving block 14 can be lifted and fixed by the second electromagnet 15. Then, the elastic buckle 19 can be pressed to disengage from the plug rod 18, allowing the fixing rod 17 to be removed from the plug rod 18 for easy cleaning of the grease adhering to the outer surface of the cone. After the fixing rod 17 is reset, the drive motor 2 can drive the second gear 7 to rotate, which in turn drives the first gear 6 meshing with the second gear 7 to rotate. This allows the tray 3 to rotate the sample container attracted by the first electromagnet 5, allowing the sample container to rotate to a position where it was not measured after the measurement, so that it can be measured again. This allows the cone to be measured again without moving and to remain in the original position, greatly reducing the measurement error caused by movement and improving the accuracy of the measuring instrument.

[0037] Working principle: After the grease is filled into the sample container, the sample container is placed inside the control base 1. The sample container is then attracted and fixed by the activation of the first electromagnet 5. Subsequently, the fan 9 and heating element 10 are activated, and the temperature of the heated air blown in is measured by the temperature sensor 11. The hot air passes through the air duct inside the control base 1 to heat the sample container, ensuring a constant temperature for both the sample container and the grease. The position of the limiting block 13 on the column 12 is then adjusted and fixed. The position of the fixing rod 17 on the insertion rod 18 is then adjusted, and the cone is fixed to the outer surface of the fixing rod 17. The moving block 14 is then moved to a suitable height and attracted and fixed by the second electromagnet 15. When measurement is required, the second electromagnet 15 is de-energized, allowing the moving block 14 to automatically descend and the cone to be inserted into the grease. The distance of the moving block 14's descent is recorded by the grating ruler assembly 16, greatly improving the accuracy of the data obtained during the use of the measuring instrument and enhancing its convenience.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
