[0001] This utility model relates to the technical field of ground flatness testing devices, specifically a flatness testing device for self-leveling construction. Background Technology

[0002] During the construction of buildings and roadbeds, the flatness of the ground needs to be tested to ensure that the indoor space can be laid with tiles more smoothly, and also to ensure that the road surface is flat and avoids excessive bumps when vehicles are driving.

In addition, after a defect is detected, the user cannot observe the defect in real time and cannot accurately locate the defect. Therefore, we propose a flatness testing device for self-leveling construction. Utility Model Content

[0020] 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.

[0021] Please see Figures 1-5A flatness testing device for self-leveling construction includes a mounting base 1. A connector 3 is tightly fitted to the outer wall of the mounting base 1. A mounting base 2 is fixedly mounted at the end of the connector 3 away from the mounting base 1. A motor 12 is fixedly mounted on the outer wall of the mounting base 1. A transmission wheel 5 is fixedly mounted on the output shaft of the motor 12. A transmission belt 6 is tumblingly connected to the middle of the transmission wheel 5. A lead screw 4 is fixedly mounted on the outer wall of the transmission wheel 5. An electromagnet 7 is threadedly connected to the outer wall of the lead screw 4. A movable plate 8 is fixedly mounted on the outer wall of the electromagnet 7. A circular groove 17 is formed in the middle of the movable plate 8. An electrode plate 20 is fixedly mounted on the top of the inner wall of the circular groove 17. A limit ring 23 is slidably connected to the inner wall of the circular groove 17. A slide rod 19 is fixedly sleeved on the inner wall of the 23. An electrode plate 22 is fixedly mounted on the bottom of the limiting ring 23. An electrode plate 21 is fixedly mounted on the bottom of the inner wall of the circular groove 17. A ball bearing 11 is rotatably connected to the bottom of the slide rod 19. An electrode plate 24 is fixedly mounted on the top of the slide rod 19. A spring 18 abuts against the top of the limiting ring 23. A fixing plate 9 is fixedly mounted on the top of the mounting base 1. A controller 10 is fixedly mounted on the top of the fixing plate 9. Mounting base 1 and mounting base 2 are both provided with mounting grooves 13 at their ends. A retaining spring 14 is sleeved on the inner wall of the mounting groove 13. A connecting pin 15 abuts against the outer wall of the retaining spring 14. A strong magnetic strip 16 is provided on the inner wall of mounting base 1, mounting base 2 and connecting piece 3.

[0022] In the above structure, the installation base 1, installation base 2, connector 3, mounting groove 13, snap ring 14, and connecting pin 15 allow the user to adapt the detection device to ground of different lengths by adding connectors 3 of different lengths. At the same time, the low cost and easy processing of installation base 1, installation base 2, and connector 3 reduce the production and processing costs of the detection device, thereby improving its application range and practicality.

[0023] In a preferred embodiment: the outer wall of the ball 11 is in rolling connection with the ground, and the distance between the second electrode plate 21 and the third electrode plate 22 is 1cm when they are in rolling connection. After the ball 11 and the third electrode plate 22 are disconnected and the limiting ring 23 rises by 1cm, the top of the fourth electrode plate 24 is connected to the bottom of the first electrode plate 20.

[0024] In the above structure, the arrangement of the ball bearing 11, electrode plate three 22, electrode plate one 20, electrode plate two 21, electrode plate three 22, and electrode plate four 24 allows the detection device to utilize the rolling of the ball bearing 11 against the ground. When the ground has unevenness, the ball bearing 11 will cause the slide rod 19 to lift the limiting ring 23, thereby bringing electrode plate four 24 into contact with electrode plate one 20. Combined with the control action of the controller 10, an electrical signal is generated when the two contact, causing the corresponding electrode plate four 24 to move. When the red and yellow dual-color indicator lights up red, it accurately locates uneven areas on the ground, making it easier for users to repair these areas. This improves the detection and positioning accuracy of the device. Conversely, when there are depressions on the ground, the ball bearing 11 will cause the spring 18 to push the limit ring 23 down due to the disappearance of the ground resistance. This causes the electrode plate 21 to contact the electrode plate 22, which in turn causes the controller 10 to light up yellow in conjunction with the red and yellow dual-color indicator light. This achieves bidirectional detection and increases the detection range of the device.

[0025] In a preferred embodiment: electrode plate 4 24 is electrically connected to electrode plate 1 20, electrode plate 21 is electrically connected to electrode plate 3 22, electrode plate 1 20 and electrode plate 3 22 are both electrically connected to controller 10, and the top of the fixing plate 9 is also provided with several red and yellow dual-color indicator lights, and the several red and yellow dual-color indicator lights are all electrically connected to controller 10.

[0026] In the above structure, through the electrode plate 21, electrode plate 3, and controller 10, during the detection operation, electrode plate 10, electrode plate 4, electrode plate 21, and electrode plate 22 respectively use the lifting and lowering of ball bearing 11 to detect the flatness of the ground. When depressions and bumps are detected, an alarm is issued in time. At the same time, the controller 10 controls the motor 12 to stop the operation, and also enables the electromagnet 7 to be energized to stop the moving plate 8. This ensures that the user can make timely repair work on the ground and avoid omissions in repairing uneven ground when it is detected. This ensures the accuracy of the user's ground repair and improves the automation and intelligence of the device.

[0027] In a preferred embodiment: the outer walls of mounting base 1, mounting base 2 and connector 3 are all provided with sliding grooves, and the inner wall of the sliding groove is fixedly assembled with the outer wall of the strong magnetic strip 16. The outer wall of electromagnet 7 is slidably connected with the outer wall of the strong magnetic strip 16, and the electromagnet 7 attracts the strong magnetic strip 16 with opposite polarities after being energized.

[0028] In the above structure, through the set slide and movable plate 8 structure, after the user has installed the detection device, the detection work can be completed by the automatic movement of the movable plate 8. Therefore, the user does not need to move the device to carry out the detection work. The user only needs to observe the status of the red and yellow dual-color indicator lights to complete the detection work, thereby improving the user's efficiency in detecting the ground.

[0029] In a preferred embodiment: the outer wall of the movable plate 8 is slidably connected to the outer walls of the mounting base 1, the mounting base 2, and the connector 3, and the mounting base 1, the mounting base 2, and the connector 3 are all made of pine wood.

[0030] In the above structure, pine wood is easy to process and has low cost, which ensures that when users perform inspection work on ground of different lengths, they only need to add connectors of different lengths 3 to complete the installation work, thereby reducing the cost of the inspection device during use and further improving the practicality of the inspection device.

[0031] In a preferred embodiment, there are two lead screws 4, and both lead screws 4 are symmetrically distributed along the outer wall of the mounting base 1. The outer walls of the mounting base 1, the mounting base 2, and the connector 3 are all tightly fitted to the wall.

[0032] In the above structure, the two lead screws 4 are used to drive both sides of the moving plate 8 to move, thereby avoiding jamming of the moving plate 8 during operation. At the same time, the motor 12, the transmission wheel 5 and the transmission belt 6 work together to drive the two lead screws 4 to rotate synchronously, thereby achieving the effect of a single motor 12 driving two lead screws 4 to rotate, thus ensuring the smoothness of the detection device during operation and the efficiency of energy utilization.

[0033] Working Principle: Firstly, during installation, users can add connectors 3 of varying lengths to adapt the device to different ground lengths, thus increasing its detection range. Secondly, when connecting mounting base 1, mounting base 2, and connectors 3, users can press the connecting pin 15 to retract it, allowing for quick connection between mounting base 1, mounting base 2, and connectors 3, thereby improving assembly efficiency. During detection, the ball bearings 11 roll along the ground due to the movement of the moving plate 8. When a protrusion appears on the ground, the ball bearings 11 move upwards towards the protrusion. This causes electrode plate 24 to contact electrode plate 20, which, in conjunction with controller 10, controls the corresponding red and yellow dual-color indicator light to illuminate red. Conversely, when there is a depression in the ground, electrode plate 22 contacts electrode plate 21, causing the red and yellow dual-color indicator light to illuminate yellow, thus achieving a bidirectional detection effect. When a protrusion or depression is detected, motor 12 will stop operating under the control of controller 10, and electromagnet 7 will be energized, causing electromagnet 7 and strong magnetic strip 16 to attract each other, keeping the moving plate 8 in place. This allows users to quickly locate and repair protrusions or depressions, improving the accuracy and efficiency of repairing protrusions and depressions in the ground.

[0034] 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.
