[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1 to 3 The utility model provides an embodiment: a calibration device for a construction engineering inspection ruler, comprising a ruler body 1, the left side of the ruler body 1 being rotatably connected to a rotating shaft 2, where the left side of the ruler body 1 is connected to the rotating shaft 2 and can rotate relative to the ruler body 2 3, the outside of the rotating shaft 2 is fixedly connected to the ruler body 2 3, the rear ends of the ruler body 1 and the ruler body 2 3 are engraved with scales, the left side of the ruler body 1 is in contact with the right side of the ruler body 2 3, where the left side of the ruler body 1 is in close contact with the right side of the ruler body 2 3, ensuring the accuracy of the measurement, and the top ends of the ruler body 1 and the ruler body 2 3 are fixedly connected to a leveling device, where the leveling device can ensure that the inspection ruler is on a stable horizontal line to prevent deviation.
[0033] The inner wall of the ruler body 2 3 is slidably connected to a cleaning component for cleaning the wall. The cleaning component includes a ball 4. The outer part of the ball 4 is slidably connected to the inner wall of the ruler body 2 3. The outer side of the ball 4 is fixedly connected to a rotating column 5. The ball 4 here provides a stable support for the rotating column 5. The outer side of the rotating column 5 is slidably connected to the inner wall of the ruler body 2 3. The outer side of the rotating column 5 is slidably connected to the inner wall of the ruler body 1. The outer side of the rotating column 5 is fixedly connected to an outer box 6. The outer side of the outer box 6 is fixedly connected to a scraper 7. The scraper 7 here can scrape and clean uneven areas on the wall, thereby improving the accuracy of the measurement.
[0034] One side of the outer box 6 is fixedly connected with a card block 18, and the left inner wall of the ruler body 2 3 is slidably connected with a card assembly for fixing the position. The card assembly includes a slide post 9, and the outer portion of the slide post 9 is slidably connected to the left inner wall of the ruler body 2 3. Here, the ruler body 2 3 provides a stable support for the slide post 9. The outer sleeve of the slide post 9 is provided with a spring 10. The front end of the slide post 9 is fixedly connected with a card block 2 11, and the top of the card block 2 11 is slidably connected to the bottom end of the card block 1 8. Here, the card block 2 11 can ensure that the card block 8 will not rotate at will. The outer portion of the card block 2 11 is slidably connected to the inner wall of the ruler body 2 3, one end of the spring 10 is fixedly connected to one side of the card block 2 11, and the other end of the spring 10 is fixedly connected to one side of the inner wall of the ruler body 2 3. Here, the card block 2 11 and the ruler body 2 3 provide a stable support for the spring 10, and one side of the ruler body 1 is fixedly connected with a protrusion 12.
[0035] Reference Figure 1 、 Figure 4 and Figure 5 The left side of the ruler body 1 is fixedly connected with a side block 13, and the ruler body 1 here provides support for the side block 13. At the same time, the side block 13 here is also the key structure for the engagement between the ruler body 1 and the ruler body 2 3. The inner wall of the side block 13 is slidably connected to the limit plate 14, and the outer side of the limit plate 14 is slidably connected to the inner wall of the ruler body 2 3. The top of the limit plate 14 is fixedly connected with a ball 15. The limit plate 14 here can prevent the ball 15 from escaping the sliding range of the side block 13. The ball 15 and the ruler body 2 3 are in an engaging relationship. A spring 2 16 is provided inside the side block 13, and one end of the spring 2 16 is fixedly connected to one side of the limit plate 14, and the other end of the spring 2 16 is fixedly connected to one side of the inner wall of the side block 13. The spring 2 16 here is to maintain the engaging relationship between the ball 15 and the ruler body 2 3 to prevent it from falling off.
[0036] Working Principle: In the initial state, ruler body 1 and ruler body 2, 3, are connected by shaft 2, parallel to each other and in close contact. The left side of ruler body 1 is connected to shaft 2, while ruler body 2, 3, is fixed to the outside of shaft 2. Scales are located at the rear ends of ruler bodies 1 and 2, 3, for reading data during measurement.
[0037] Before taking a measurement, ensure the wall is clean and flat. This is where the cleaning assembly comes into play. Ball bearings 4 slide along the inner walls of ruler body 2 3 and ruler body 1 1, driving the rotating column 5 and outer box 6. Scrapers 7 on the outside of outer box 6 scrape against the wall, cleaning any uneven areas and improving measurement accuracy.
[0038] After cleaning is complete, the slide post 9 slides along the inner wall of the ruler body 2 3, pushing the block 2 11 outward until the top of the block 2 11 abuts against the bottom of the block 1 8, locking the block. At this point, the spring 10 is compressed, providing the necessary elastic force to ensure a tight connection between the block 2 11 and the block 1 8, preventing them from loosening during use.
[0039] Both ruler body 1 and ruler body 2 are equipped with leveling devices at their tops to ensure the device is level during measurement. If the device is not level, adjust the relative angle of ruler body 1 and ruler body 2 until the leveling device is level.
[0040] After confirming the device is level and fixed in position, you can move it along the wall to measure. The scales on the first and second bodies 3 are used to read the measurement value, and the contact surface of the first and second bodies 3 ensures measurement stability.
[0041] After the measurement is completed, the ruler body 1 can be rotated. At this time, the ball 15 will move downward with the cooperation of the limit plate 14 and the spring 2 16, thereby canceling its engagement with the ruler body 2 3. Then, the protrusion 12 is aligned with the groove at the front end of the ruler body 2 3 and engaged. The ruler body 1 and the ruler body 2 3 can be folded to reduce the volume, making it easier to carry and store the device.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
