Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, it relates to a portable flatness testing device for building engineering. Background Technology

[0002] Flatness refers to the fact that the surface of something is not perfectly flat during processing or production. The difference between the unevenness produced during processing and the absolute level is the flatness. In building engineering inspection, the surface flatness of the walls, floors, etc. of a building not only affects the appearance of the building, but also has a certain impact on the stability of the building's surface decoration layer. The surface flatness of a building must be within the error data index specified by the state, which requires the use of testing equipment for detection.

[0003] However, existing flatness testing equipment has a lot of electronic components at the top, which leads to high production costs. In addition, this type of testing equipment is prone to damage, which increases the cost of using the device.

[0004] Furthermore, the structure of the testing equipment is relatively simple and lacks a rapid marking function. This means that after uneven areas are measured on the exterior wall, manual marking with a marker is required, which affects the testing efficiency. Utility Model Content

[0015] The present invention is further provided with a pressing block fixed on the outer wall of the top plate to facilitate pressing down the top plate.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a portable flatness testing device for building engineering, which has the following advantages:

[0018] 1. By setting a contact rod, bracket, wheels, and scale on the base plate, the user can press the top plate and contact rod towards the wall using the pressing block, causing the wheels to contact the wall. At this time, the unevenness of the wall will compress the wheels and contact rod, thereby deforming the first spring. The user can then observe the extension length of the contact rod by observing the scale to see if it is consistent, thus achieving the detection effect. Compared with detection equipment that integrates electronic components, this design has a simpler structure and lower cost, reducing the operating cost of the device.

[0019] 2. By incorporating a marker pen, a second spring, and a retaining ring, when uneven areas are detected on the building wall, the user can press down on the marker pen to mark them, facilitating quick location and repair later. The user can also remove the marker pen by turning the tightening screw for easy replacement, increasing the overall speed of the device during inspection.

[0020] 3. By setting up a shoulder strap, nuts, and threaded posts, the user can place the nuts at both ends of the shoulder strap onto the upper end of the threaded posts, and then rotate the nuts to install them onto the upper end of the threaded posts, thereby achieving the effect of fixing the shoulder strap to the base plate. With this design, the user can carry the device with the shoulder strap, making it more convenient to use. Attached Figure Description

A pressing block 28 is fixedly installed on the outer wall of the top plate 4.

[0031] In this embodiment, a second spring 15 is fixedly provided at the outer end of the circular hole 13 and on the upper surface of the base plate 1. A retaining ring 16 is fixedly provided at the upper end of the second spring 15. The marker 14 is located inside the retaining ring 16.

[0032] More specifically, the user can first place the device on the wall, and then press the top plate 4 and contact rod 8 towards the wall using the pressing block 28, so that the wheel 10 contacts the wall. At this time, the unevenness of the wall will squeeze the wheel 10 and contact rod 8, thereby deforming the first spring 12.

[0035] Please refer to Figure 1 As a further embodiment for convenient observation of the extension length of the contact rod 8: a scale 27 is provided on the outer wall of the contact rod 8.

[0036] Specifically, users can use the scale 27 to check the extension length of the contact rod 8 to see if it is consistent, in order to judge the flatness of the wall surface.

[0037] In summary, when using the device, the user can first place it on the wall, and then press the top plate 4 and contact rod 8 towards the wall using the pressing block 28, so that the wheel 10 contacts the wall. At this time, the unevenness of the wall will squeeze the wheel 10 and contact rod 8, thereby deforming the first spring 12. The user can then observe the extension length of the contact rod 8 by observing the scale 27 to see if it is consistent, thus achieving the detection effect. When an uneven position is detected in the building wall, the user can press down the marker pen 14 to mark it, so as to facilitate quick search and repair later. The user can also remove the marker pen 14 by rotating the tightening screw 18 for easy replacement, increasing the overall speed of the device during detection.
