Description

Technical Field

[0001] The present application relates to the field of housing construction technology, and in particular to a device for detecting the flatness of interior and exterior walls of a house. Background Art

[0002] The interior and exterior walls of a building generally refer to the wall structures inside and outside the building. In construction, the interior and exterior walls assume multiple functions such as support, heat insulation, sound insulation, and decoration. Therefore, the exterior walls have high requirements for flatness, which directly affects the structural stability and aesthetic appearance of the building. The flatness detection device can ensure that the wall flatness meets the design requirements, avoid problems such as unevenness and deformation of the wall surface, and ensure the overall quality and appearance of the building. Secondly, the flatness detection device can help construction workers to identify problems during the construction process and promptly correct wall flatness that does not meet the standard, thereby improving construction efficiency, reducing secondary repair costs, and reducing waste.

[0003] Chinese utility model patent number CN221404179U discloses a device for detecting the flatness of interior and exterior walls of a house. The device comprises a long plate, with fixed plates fixedly connected to the upper and lower sides of the long plate. A movable rod is slidably connected to the interior of the fixed plate. A spring is sleeved on the exterior of the movable rod. The right end of the movable rod is fixedly connected to a connecting plate, the left end of the movable rod is fixedly connected to a piston plate, the left end of the fixed plate is fixedly connected to a sleeve, and the left end of the sleeve is fixedly connected to a suction cup. Two measuring assemblies are provided inside the long plate. This utility model realizes the detection of the flatness of the interior and exterior walls of a house. It has a simple structure and is more convenient and flexible to use, which is convenient for construction personnel to operate and maintain. It can also be fixed to the wall to detect flatness, thereby providing a more stable measurement environment, reducing the influence of external factors on the measurement results, and thus improving the accuracy and reliability of the detection.

[0004] When the flatness detection device is in use, a suction cup is used to fix the flatness detection device on the wall. The suction cup has unstable adsorption force and has high requirements for the wall surface. If the flatness detection device is heavy, there is a risk of the suction cup falling off, and the flatness detection device cannot be safely and firmly positioned at the location where measurement is required. Utility Model Content

[0005] In order to ensure that the flatness detection device is safely and firmly located at the position where measurement is required, the present application provides a flatness detection device for the interior and exterior walls of a house.

[0006] This application provides a device for detecting the flatness of interior and exterior walls of a house, which adopts the following technical solution:

[0007] A device for detecting the flatness of interior and exterior walls of a house comprises a detection plate, a detection assembly is provided on the detection plate, a lifting assembly is provided at the bottom of the detection plate, the lifting assembly comprises a lifting seat, a support column and a motor, the support column is provided at the bottom of the detection plate, a sliding plate is provided at one end of the support column away from the detection plate, the sliding plate is slidingly provided on the lifting seat, the motor is provided at the bottom of the lifting seat, a threaded rod is coaxially fixed to the motor shaft of the motor, the sliding plate is threadedly connected to the threaded rod, the forward and reverse rotation of the motor drives the threaded rod to rotate, and the sliding plate slides toward or away from the motor.

[0008] By adopting the above technical solution, when it is necessary to detect the flatness of the interior and exterior walls of a house, the lifting seat contacts the ground, the motor drives the threaded rod to rotate, causing the sliding plate to slide, and the support column drives the detection plate to rise and fall. The detection plate can be fixed at the position to be detected and can be adjusted appropriately. The flatness detection device is safely and firmly located at the position to be measured.

[0009] Optionally, the lifting seat is provided with a cavity for accommodating a sliding plate, the sliding plate slides vertically in the lifting seat cavity, the lifting seat is provided with a through hole for the support column to pass through, and the sliding plate drives the support column to slide along the axis direction of the through hole.

[0010] By adopting the above technical solution, the sliding plate slides stably in the cavity and is not easy to separate from the lifting seat. The detection plate rises and falls stably when passing through the support column.

[0011] Optionally, the detection assembly includes a sliding block, a fixed block and a detection ruler, the detection plate is provided with a sliding groove for the sliding block to slide, the sliding block slides along the length direction of the sliding groove, the fixed block is arranged on the sliding block, the fixed block is provided with a detection groove for accommodating the detection ruler, the fixed block is provided with a scale bar, the detection ruler is provided with a positioning block, the fixed block is provided with a positioning groove for the positioning block to slide, and the positioning block slides along the length direction of the positioning groove.

An adjusting screw is threadedly connected to the threaded hole, and the adjusting screw is set on the fixed block. When the adjusting screw rotates, it drives the fixed block to slide.

[0014] By adopting the above technical solution, the adjusting screw is rotated to make the sliding block slide in the limiting groove. When the flatness detection device does not directly abut the wall, the screw can be adjusted for fine adjustment so that the detection ruler abuts the inner and outer wall surfaces, which reduces the difficulty of use and does not require adjusting the lifting seat to make the detection ruler abut the inner and outer wall surfaces.

[0015] Optionally, a sliding spring is provided at the bottom of the detection groove, the elastic force direction of the sliding spring is parallel to the length of the detection ruler, one end of the sliding spring is provided at the bottom of the detection groove, and the other end is provided at one end of the detection ruler close to the fixed block.

[0016] By adopting the above technical solution, the sliding spring allows the detection ruler to always abut against the inner and outer walls, making it convenient for the inspection personnel to read the changes in the scale through the ruler.

[0017] Optionally, a shift block is provided at one end of the adjusting screw away from the sliding block.

[0018] By adopting the above technical solution, the shift block allows the inspector to hold it better and easily adjust the rotation of the screw.
