Description

Technical Field

[0001] This utility model relates to the field of thickness detection technology, and in particular to a thickness gauge for detecting the thickness of building waterproof coatings. Background Technology

[0002] Building waterproofing coatings are key materials for ensuring the waterproofing performance of buildings. They are mostly high-molecular synthetic materials that are viscous liquids at room temperature. After being applied, they can form a tough waterproof film on the substrate surface through solvent evaporation, water evaporation, or reaction curing. Common types include polyurethane, polymer cement, asphalt, and modified asphalt waterproofing coatings. After the waterproofing construction is completed, a sample of the waterproofing layer needs to be inspected using a thickness gauge.

[0003] Existing technologies, such as the utility model with publication number CN220602379U, relate to the field of measuring rulers. Specifically, a frosted pad is adhesively adhered to the side wall of the handle, the top of the handle is mounted on the bottom of a supporting base plate, a back plate is mounted on the side wall of the supporting base plate via a disassembly and assembly mechanism, and a scale plate is connected to the outer walls of the front and rear sides of the back plate via a sliding mechanism. A scale is installed in the middle of the left outer wall of the back plate. This utility model can reliably measure and observe the thickness of acrylic casting sheets, effectively solving the problem of data errors caused by visual inspection in traditional devices, thus improving the accuracy of the test data.

[0004] However, after the test is completed, sand, dust and other particles in the sample may adhere to the test plate. When the thickness of the waterproof coating is tested again, it is difficult for the probe to make close and accurate contact with the coating surface. Tiny sand particles will form gaps between the sample and the test plate, causing the thickness gauge to measure the distance from the probe to the sand particles, rather than the actual thickness of the coating, resulting in a deviation in the measurement results. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that after the test is completed, sand, dust and other particles in the sample may adhere to the test plate. When the thickness of the waterproof coating is tested again, it is difficult for the probe to make close and accurate contact with the coating surface. Tiny sand particles will form gaps between the sample and the test plate, causing the thickness gauge to measure the distance from the probe to the sand particles instead of the actual thickness of the coating, resulting in a deviation in the measurement results. Therefore, this invention proposes a thickness gauge for testing the thickness of building waterproof coatings.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a thickness gauge for detecting the thickness of a building waterproof coating, comprising a body and a scraping device. A detector is fixedly mounted on the surface of the body, and a contact rod is mounted on the surface of the detector. A disc is fixedly connected to the surface of the body, and the contact rod is positioned directly above the disc. The scraping device includes a pull rod, which is slidably connected to the disc. A scraper is fixedly connected to the upper surface of the pull rod, penetrating the disc. A groove is formed on the surface of the disc, and the scraper is adapted to the groove. A stop is rotatably connected to the lower surface of the pull rod, and a protrusion is fixedly connected to the surface of the stop. A bracket is fixedly connected to the inner wall of the body, and a through hole is formed at the center of the bracket. The protrusion is adapted to the through hole. A centering component is provided on the surface of the disc. By setting up the scraping device, impurities on the disc surface are cleaned promptly, reducing the possibility of measurement deviations due to impurities. This ensures that each test accurately reflects the thickness of the waterproof coating, greatly simplifies cleaning work, reduces the number of interruptions in the testing process, maintains work rhythm, improves testing efficiency, and ensures the continuity and integrity of the test data.

[0007] Preferably, a pressure spring is fixedly connected to the lower surface of the disc body, and a gasket is fixedly connected to the end of the pressure spring away from the disc body. By setting the pressure spring, when the scraper cleans the impurities on the surface of the disc body and re-fits it with the slot, the original restraint of the pressure spring is released, and the elastic force squeezes the gasket. Under the elastic force of the pressure spring, the gasket squeezes the stop block, and the stop block drives the protrusion through the bracket.

[0008] Preferably, the gasket is sleeved with the pull rod, and the gasket abuts against the stop block.

[0009] Preferably, a knob is fixedly connected to the lower surface of the stop block. The stop block is located on the lower surface of the bracket. By setting the stop block, when the cleaning of impurities in the disc is completed and the scraper needs to be reset and fixed, the pressure spring loses its restraint and generates elastic force to squeeze the pad. The pad pushes the stop block to move, and the stop block drives the protrusion through the bracket. Then, the knob is rotated to make the protrusion and the bracket tightly abut against each other.

[0010] Preferably, the centering component includes a collar that is slidably connected to the disc body. A stop block is fixedly connected to the upper surface of the collar. Ear plates are spaced apart along the outer edge of the upper surface of the disc body. Rectangular holes are formed on the ear plates. A sliding plate is slidably connected to the inner wall of the rectangular holes. A handle is fixedly connected to one side of the collar. By setting the centering component, the sample can be accurately pushed to the center position of the disc body, ensuring the consistency and standardization of the measurement position, effectively eliminating measurement errors caused by sample position deviation, making the test results more reliable, and more accurately reflecting the actual thickness of the waterproof coating.

[0011] Preferably, a fixed spring is connected between the end of the slide away from the abutment block and the ear plate. By setting the fixed spring, when the tester grabs the handle and pulls the collar upward, the abutment block pushes the slide to push the sample to the center of the disc. After releasing the handle, the fixed spring, which was originally compressed, is released and immediately releases its elastic potential energy, generating a strong elastic force.

[0012] Preferably, the upper surface of the abutment block is provided with an angle, and the side of the sliding plate near the abutment block is adapted to the abutment block. There are three sliding plates, which are arranged in a circular array. By setting the sliding plates, when the test sample is placed on the disk, the user pulls the collar, and the collar drives the abutment block to push the sliding plate to slide. Due to its planar structure, the sliding plate can apply a uniform and stable pushing force to the sample and push the sample smoothly to the center of the disk.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a scraping device, after the test is completed, rotating the knob causes the protrusion to align with the bracket and presses the pull rod upward. The pull rod pushes the scraper out of the slot. Then, rotating the scraper causes it to rub against the surface of the disc, cleaning the impurities on the disc surface. Afterward, the scraper and the slot are re-fitted, and the pressure spring, no longer restrained, generates elastic force to squeeze the pad. The pad squeezes the stop block, causing the protrusion to pass through the bracket. At this time, rotating the knob causes the protrusion to abut against the bracket, thus fixing the scraper and reducing the possibility of the scraper coming off during the test. By setting up a scraping device, impurities on the disc surface are cleaned in a timely manner, reducing the possibility of measurement deviations caused by impurities. This ensures that each test accurately reflects the thickness of the waterproof coating, greatly simplifies the cleaning work, reduces the number of interruptions in the testing process, maintains the work rhythm, improves the efficiency of the testing work, and ensures the consistency and integrity of the test data.

[0015] In this invention, by setting a centering component, during testing, the sample is placed on the disc, then the handle is grasped and the collar is pulled upwards. As the collar slides upwards, it causes the abutment block to abut against the slide plate. The slide plate slides under force, squeezing the sample and pushing it to the center of the disc. Then, the handle is released, and the collar moves downwards under the influence of gravity, causing the abutment block to move away from the slide plate. At this time, the fixing spring loses its restraint and generates elastic force to squeeze the slide plate back to its original position, thus allowing the thickness to be measured. By setting a centering component, the sample can be accurately pushed to the center of the disc, ensuring the consistency and standardization of the measurement position, effectively eliminating measurement errors caused by sample position deviation, making the test results more reliable, and more accurately reflecting the actual thickness of the waterproof coating.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a thickness gauge for detecting the thickness of a building waterproof coating, including a body 1 and a scraping device 5. The body 1 is U-shaped with an opening on one side. An opening is provided at one bottom end of the body 1. A detector 2 is fixedly installed on the surface of the body 1. A touch rod 3 is installed on the surface of the detector 2. A disc 4 is fixedly connected to the surface of the body 1. The disc 4 is located above the bottom opening of the body 1, and the touch rod 3 is located directly above the disc 4.

[0023] In this implementation scheme: the scraping device 5 includes a pull rod 53, which is slidably connected to the disc body 4. The upper surface of the pull rod 53 passes through the disc body 4 and is fixedly connected to a scraper 51. A slot is opened on the surface of the disc body 4, and the scraper 51 is adapted to the slot. A stop block 57 is rotatably connected to the lower surface of the pull rod 53. A protrusion 56 is fixedly connected to the surface of the stop block 57. A bracket 52 is fixedly connected to the inner wall of the machine body 1. The bracket 52 is located in the bottom opening of the machine body 1. A through hole is opened in the center of the bracket 52, and the protrusion 56 is adapted to the through hole. A centering component 59 is provided on the surface of the disc body 4. By setting up the scraping device 5, impurities on the surface of the disc body 4 are cleaned in time, reducing the deviation of measurement results caused by impurities, ensuring that each test can truly reflect the thickness of the waterproof coating, greatly simplifying the cleaning work, reducing the number of interruptions in the testing process, maintaining the work rhythm, improving the efficiency of the testing work, and ensuring the continuity and integrity of the test data.

[0024] Specifically, a pressure spring 54 is fixedly connected to the lower surface of the disc body 4. The pressure spring 54 is sleeved on the pull rod 53. A gasket 55 is fixedly connected to the end of the pressure spring 54 away from the disc body 4. By setting the pressure spring 54, when the scraper 51 cleans the impurities on the surface of the disc body 4 and re-sleeves with the slot, the original restraint on the pressure spring 54 is released, and the elastic force squeezes the gasket 55. Under the elastic force of the pressure spring 54, the gasket 55 squeezes the stop block 57, and the stop block 57 drives the protrusion 56 to pass through the bracket 52.

[0025] Specifically, the gasket 55 is fitted onto the pull rod 53, and the gasket 55 abuts against the stop block 57.

[0026] Specifically, a knob 58 is fixedly connected to the lower surface of the stop 57. The stop 57 is located on the lower surface of the bracket 52. By setting the stop 57, when the cleaning of impurities in the disc 4 is completed and the scraper 51 needs to be reset and fixed, the pressure spring 54 loses its restraint and generates elastic force to squeeze the pad 55. The pad 55 pushes the stop 57 to move. The stop 57 drives the protrusion 56 to pass through the bracket 52. Then, the knob 58 is rotated so that the protrusion 56 and the bracket 52 are tightly abutted.

[0027] Specifically, the centering component 59 includes a collar 591, which is slidably connected to the disc body 4. A stop block 592 is fixedly connected to the upper surface of the collar 591. Ear plates are spaced apart on the outer edge of the upper surface of the disc body 4. Rectangular holes are opened on the ear plates. A sliding plate 593 is slidably connected to the inner wall of the rectangular holes. The sliding plate 593 is perpendicular to the stop block 592. The sliding plate 593 is T-shaped. The outer side of the sliding plate 593 moves in cooperation with the stop block 592. The inner side of the sliding plate 593 is an arc plate used to cooperate with the sample. A handle 595 is fixedly connected to one side of the collar 591. By setting the centering component 59, the sample can be accurately pushed to the center position of the disc body 4, ensuring the consistency and standardization of the measurement position, effectively eliminating the measurement error caused by the deviation of the sample position, making the test results more reliable, and more accurately reflecting the actual thickness of the waterproof coating.

[0028] Specifically, a fixing spring 594 is connected between the end of the sliding plate 593 away from the abutment block 592 and the ear plate.

[0029] In this embodiment: by setting a fixed spring 594, when the tester grasps the handle 595 and pulls the collar 591 upward, the abutment block 592 pushes the slide plate 593 to push the sample to the center of the disc 4, and then releases the handle 595, the fixed spring 594 is released from its original compressed state and immediately releases its elastic potential energy, generating a strong elastic force.

[0030] Specifically, the upper surface of the abutment block 592 is provided with an angle, and the side of the sliding plate 593 near the abutment block 592 is adapted to the abutment block 592. There are three sliding plates 593, and the three sliding plates 593 are arranged in a circular array.

[0031] In this embodiment: by setting up a sliding plate 593, when the test sample is placed on the disk 4, the user pulls the collar 591, the collar 591 drives the abutment block 592 to push the sliding plate 593 to slide. The sliding plate 593, with its planar structure, can apply a uniform and stable pushing force to the sample and push the sample smoothly to the center position of the disk 4.

[0032] Working principle: By setting up the scraping device 5, after the test is completed, rotating the knob 58 drives the protrusion 56 to correspond with the bracket 52 and pushes the pull rod 53 upward. The pull rod 53 pushes the scraper 51 out of the slot. Then, the scraper 51 is rotated. While rotating, the scraper 51 rubs against the surface of the disc 4 to clean the impurities on the surface of the disc 4. Then, the scraper 51 is re-fitted with the slot. The pressure spring 54 is released and generates elastic force to squeeze the pad 55. The pad 55 squeezes the stop block 57 and drives the protrusion 56 to pass through the bracket 52. At this time, rotating the knob 58 drives the protrusion 56 to abut against the bracket 52, which can fix the scraper 51 and reduce the possibility of the scraper 51 coming off during the test. By setting up the scraping device 5, impurities on the surface of the disc 4 are cleaned in time, reducing the possibility of deviation in measurement results caused by impurities. This ensures that each test can accurately reflect the thickness of the waterproof coating, greatly simplifies the cleaning work, reduces the number of interruptions in the test process, maintains the work rhythm, improves the efficiency of the test work, and ensures the consistency and integrity of the test data.

[0033] By setting the centering component 59, during testing, the sample is placed on the disc 4, then the handle 595 is grasped and the collar 591 is pulled upwards. As the collar 591 slides upwards, it causes the stop block 592 to abut against the slide plate 593. The slide plate 593 slides under force, squeezing the sample and pushing it to the center of the disc 4. Then, the handle 595 is released, and the collar 591 moves downwards under the influence of gravity, causing the stop block 592 to move away from the slide plate 593. At this time, the fixing spring 594 loses its restraint and generates elastic force to squeeze the slide plate 593 back to its original position, thus allowing the thickness to be measured. By setting the centering component 59, the sample can be accurately pushed to the center of the disc 4, ensuring the consistency and standardization of the measurement position, effectively eliminating measurement errors caused by sample position deviation, making the test results more reliable, and more accurately reflecting the actual thickness of the waterproof coating.
