Description

Technical Field

[0001] This utility model relates to the field of wall inspection technology, specifically a wall surface flatness inspection device. Background Technology

[0002] During building construction or interior decoration, specialized testing devices are needed to inspect the flatness of wall surfaces to ensure their smoothness. Existing wall surface flatness testing devices, such as the one disclosed in CN218268120U, use a level for measurement. By rotating a turntable, the connecting shaft is rotated, thereby adjusting the height of the level and allowing measurement of different wall heights. The first slider and clamp can be detached, allowing for handheld measurement of the level, thus providing multiple usage methods for the device.

[0003] However, the existing technical solutions mentioned above still have some shortcomings in actual use. The existing detection devices mainly use a level to measure the surface flatness during actual testing. However, the level is a rectangular strip structure. In the actual testing process, when the wall is uneven, it is not possible to accurately determine the location of the unevenness and the difference in flatness, which makes it difficult to provide accurate data for subsequent wall correction. Therefore, it is necessary to design a wall surface flatness detection device to better meet the actual use needs. Utility Model Content

[0004] The purpose of this invention is to provide a wall surface flatness detection device to solve the problem mentioned in the background art that the location of wall unevenness and the difference in flatness cannot be accurately determined.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall surface flatness detection device, comprising a fixing plate, a threaded rod connected to a bearing inside the fixing plate, and a knob fixed to the front end of the threaded rod through the fixing plate;

[0006] Also includes:

[0007] Mounting plate, symmetrically fixed on the fixed plate, with cylinders fixed at equal intervals on the upper surface of the mounting plate, and movable plates at equal intervals below the mounting plate, with vertical rods fixed vertically on the upper surface of the movable plates;

[0008] A crossbar is connected to the threaded rod by a thread, and the crossbar is located on the front side of the mounting plate.

[0009] Preferably, a handle is fixed to the upper end of the fixed plate, and a foam anti-slip sleeve is fixed to the surface of the handle. The handle makes it easy to carry the entire device, and the foam anti-slip sleeve can increase the friction between the handle and the user's hand, preventing the device from slipping.

[0010] Preferably, the cylinder and the movable plate are distributed in a one-to-one correspondence, and the cylinder is made of transparent pressure acrylic sheet, and the surface of the cylinder is marked with scale lines. Through the transparent structure of the cylinder and the scale lines, the flatness difference can be easily determined.

[0011] Preferably, a rolling ball is installed on the lower end face of the movable plate, and one end of a spring is fixed on the upper end face of the movable plate, while the other end of the spring is fixed to the lower end face of the mounting plate. The ball facilitates the movement of the device, and the elasticity of the spring provides a basic force for the automatic reset of the movable plate.

[0012] Preferably, the vertical rod can slide up and down through the mounting plate, and an indicator plate is fixed at the upper end of the vertical rod. The indicator plate works in conjunction with the cylindrical scale to indicate data. The indicator plate can be moved by the sliding action between the vertical rod and the mounting plate. The difference in flatness of the wall surface can be accurately determined by the indicator plate and the cylindrical scale.

[0013] Preferably, the crossbar passes through the fixed plate and can slide back and forth, and there are sliding rods fixed at equal intervals on the crossbar. When the crossbar moves, the sliding guidance between the crossbar and the fixed plate can ensure the stability of the crossbar's movement.

[0014] Preferably, the slide bar and the mounting plate are slidably connected, and the slide bar and the vertical bar are distributed in a one-to-one correspondence. The sliding action between the slide bar and the mounting plate can provide a basic force for locking and unlocking the vertical bar.

[0015] Preferably, a clamping plate is also fixed on the slide rod, and the clamping plate is set inside the mounting plate. Limiting teeth are also evenly fixed on the clamping plate. At the same time, the limiting teeth can achieve the limiting function by contacting the vertical rod. By adjusting the position of the slide rod and the clamping plate, the limiting teeth can be made to contact the vertical rod to achieve the limiting function, which facilitates the observation of the flatness difference later.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This wall surface flatness detection device adopts multiple sets of moving measuring mechanisms, which can effectively detect whether the wall surface is flat and accurately determine the unevenness of the wall surface for later repair. Combined with the locking mechanism and the indicating mechanism, it can easily determine the wall flatness difference, determine whether the wall meets the construction standards, and provide data support for whether the wall needs repair. The specific details are as follows:

[0017] This wall surface flatness detection device is equipped with a vertical rod. When detecting the flatness of the wall, the device uses a movable plate, ball bearings, vertical rod, indicator plate, and scale on a cylinder to determine whether the wall is flat. Furthermore, it can accurately determine the location of unevenness and the overall difference in flatness based on the data indicated by the indicator plate at different positions, providing data support for subsequent wall repair.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a wall surface flatness detection device, including a fixed plate 1, a threaded rod 3 connected to a bearing inside the fixed plate 1, and a knob 4 fixed through the front end of the threaded rod 3 through the fixed plate 1; it also includes: a mounting plate 5, which is symmetrically fixed on the fixed plate 1, with cylinders 6 fixed at equal intervals on the upper surface of the mounting plate 5, and movable plates 7 arranged at equal intervals below the mounting plate 5, with vertical rods 8 fixed vertically on the upper surface of the movable plates 7; and a horizontal rod 9, which is connected to the threaded rod 3 by threads and is located on the front side of the mounting plate 5.

[0026] A handle 2 is fixed to the upper end of the fixed plate 1, and a foam anti-slip sleeve is fixed to the surface of the handle 2; cylinders 6 and movable plates 7 are distributed in a one-to-one correspondence, and cylinders 6 are made of transparent pressure acrylic sheets, with scale lines marked on their surfaces; a rolling ball bearing 701 is installed on the lower end face of the movable plate 7, and one end of a spring 702 is fixed to the upper end face of the movable plate 7, with the other end of the spring 702 fixed to the lower end face of the mounting plate 5; a vertical rod 8 passes through the mounting plate 5 and can slide up and down, and an indicator disc 801 is fixed to the upper end of the vertical rod 8. The indicator dial 801 works in conjunction with the scale lines on the cylinder 6 to indicate data; the crossbar 9 passes through the fixed plate 1 and can slide back and forth, and slide rods 10 are fixed at equal intervals on the crossbar 9; the slide rods 10 and the mounting plate 5 are slidably connected, and the slide rods 10 and the vertical rods 8 are distributed in a one-to-one correspondence; a clamping plate 1001 is also fixed on the slide rod 10, and the clamping plate 1001 is set inside the mounting plate 5, and the clamping plate 1001 is also evenly fixed with limiting teeth 1002, and the limiting teeth 1002 contact with the vertical rods 8 to achieve a limiting function.

[0027] When using this wall surface flatness testing device, such as Figure 1 , Figure 2 and Figure 5 As shown, the device can be easily moved by holding the handle 2. The device is then aligned with the wall to be inspected. At this time, the ball bearing 701 contacts the wall. The rolling action of the ball bearing 701 allows for easy adjustment of the position of the entire device. After adjustment, pressing the handle 2 causes the fixed plate 1 and the mounting plate 5 to move relative to the movable plate 7. At this time, the spring 702 contracts under force, and the vertical rod 8 slides under force until the fixed plate 1 contacts the wall. When the vertical rod 8 moves, it simultaneously drives the indicator plate 801 to slide inside the cylinder 6. The scale line indicated by the indicator plate 801 on the cylinder 6 can be used to determine whether the wall is flat. Based on the values ​​read from different positions, the location of unevenness in the wall can be accurately determined for later repair.

[0028] When conducting testing, and after the testing is completed, it is necessary to record the test data, such as... Figure 1 , Figure 3 and Figure 4 As shown, simply turning knob 4 will rotate the threaded rod 3. Through the threaded connection between the threaded rod 3 and the horizontal bar 9, the sliding rod 10 can be moved, thereby moving the clamping plate 1001 and the limiting tooth 1002. When the limiting tooth 1002 contacts the vertical bar 8 and generates pressure, it can limit the vertical bar 8. This makes it convenient to remove the device after measurement and record the measurement data. By recording the data, it can be determined whether the wall's standard flatness difference meets the construction standards, providing data support for whether the wall needs to be repaired later. This is the working principle of the wall surface flatness detection device.

[0029] 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.
