Description

Technical Field

[0001] The utility model belongs to the technical field of building material detection, and specifically refers to a flatness detector for building materials. Background Art

[0002] Building materials are various materials used in construction projects. After the building materials are processed, it is necessary to detect the flatness of their surfaces. If the surface flatness is insufficient, gaps are likely to be formed during construction, affecting the project quality.

[0003] A flatness detection device for building materials in a construction project disclosed in the patent with the publication number of CN216361586U starts the motor to move the movable plate left and right. The rotation of the movable plate is restricted by the limiting rod, thereby driving the sleeve to move left and right, making the pulley slide on the top of the building material plate. When encountering an uneven position, the pulley will move up and down, driving the indicating arrow to point to different scales on the detection ruler, achieving the effect of simple structure and convenient use of the detection device.

[0004] However, due to the small change value of the flatness of building materials and the relatively fine pointer scale, it is inconvenient for operators to observe, and it is easy to miss or misdetect. Moreover, since building materials are mostly exposed to the outside, they are likely to be attached with particulate debris, and the debris is likely to affect the detection result of flatness during the detection process, resulting in detection errors. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing monitoring equipment is inconvenient for observing the change value of flatness, and it is easy to miss or misdetect. Moreover, when detecting building materials, the debris adhered to the surface is likely to affect the detection result, resulting in detection errors.

[0006] To achieve the above functions, the technical solution adopted by the utility model is as follows: a flatness detector for building materials, including a detection table, and further including a movable detection mechanism and a pressing and positioning mechanism arranged on the detection table; the movable detection mechanism includes a support plate and an electric push rod. The support plates are arranged at both ends of the detection table. A guide rod and a lead screw are arranged between the two groups of support plates. The lead screw is rotatably arranged. A slider is threadedly connected to the lead screw. The slider is slidably arranged on the guide rod. The electric push rod is arranged on the bottom wall of the slider. An installation plate is arranged on the electric push rod. A detection component and a cleaning component are installed on the installation plate.

[0007] Further, the detection component includes a detection box and a connecting rod. The detection box is installed on one side of the mounting plate. An activity cavity is provided inside the detection box. A first piston is movably arranged inside the activity cavity. An air hole is provided on the bottom wall of the activity cavity. A column tube is provided on the top wall of the activity cavity. A second piston is movably arranged inside the column tube. The connecting rod is connected to the bottom wall of the first piston. The connecting rod movably penetrates through the bottom wall of the activity cavity and is provided with a connecting frame. A spring is provided between the connecting frame and the bottom wall of the detection box. A roller is rotatably arranged on the connecting frame.

[0008] Further, an observation window is provided on the detection box. A transparent plate is provided on the observation window. Scale markings are provided on the transparent plate. The scale markings are arranged close to the column tube.

[0009] Further, the cleaning component includes an air pump and an air pipe. The air pump is installed on the other side of the mounting plate. The air pipe is connected to the air pump. The end of the air pipe is arranged close to both sides of the roller.

[0010] Preferably, the pressing and positioning mechanism includes a pressing plate and a screw rod. The pressing plate movably penetrates through both ends of the detection table. The screw rod is rotatably arranged on the bottom wall of the detection table. The screw rod is threadedly connected to the pressing plate.

[0011] Preferably, the pressing plate is arranged in a U shape. A cushion plate is provided on the top wall of the pressing plate. The material of the cushion plate is rubber.

[0012] The beneficial effects of the present utility model adopting the above structure are as follows:

[0013] 1. By arranging a lead screw and a guide rod, cooperating with a slider and an electric push rod, the mounting plate can be driven to translate. By using the connecting frame, the roller and the spring, the connecting rod can be driven to move according to the undulation of the building material. The connecting rod drives the first piston to move, so that the first piston squeezes the liquid in the activity cavity into the column tube. Since the cross-section of the activity cavity is much larger than that of the column tube, when the volume remains unchanged, the moving height of the liquid in the column tube can be increased, and the moving distance of the second piston can be amplified. Cooperating with the scale markings, it is convenient for observation and recording.

[0014] 2. By arranging an air pump and cooperating with an air pipe, the building material above the moving direction of the moving wheel can be cleaned, avoiding the influence of adhered sundries on the detection result and improving the detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following will further describe the present utility model in detail with reference to the accompanying drawings.

[0022] Such as Figures 1-4As shown in the figure, a flatness detector for building materials proposed by the present utility model includes a detection table 1, and further includes a movable detection mechanism 2 and a pressing and positioning mechanism 3 arranged on the detection table 1; the movable detection mechanism 2 includes a support plate 4 and an electric push rod 5. The support plates 4 are arranged at both ends of the detection table 1. A guide rod 6 and a lead screw 7 are arranged between the two groups of support plates 4. The lead screw 7 is rotatably arranged. A slider 8 is threadedly connected to the lead screw 7. The slider 8 is slidably arranged on the guide rod 6. The electric push rod 5 is arranged on the bottom wall of the slider 8. An installation plate 9 is arranged on the electric push rod 5. A detection component 10 and a cleaning component 11 are installed on the installation plate 9. Place the building materials on the detection table 1, fix the building materials by using the pressing and positioning mechanism 3, start the electric push rod 5 to drive the installation plate 9 to move. The installation plate 9 drives the detection component 10 and the cleaning component 11 to approach the building materials. By starting the motor connected to the lead screw 7, drive the lead screw 7 to rotate. The lead screw 7 drives the slider 8 to move along the guide rod 6, so that the slider 8 drives the electric push rod 5 to move, and further drives the detection component 10 and the cleaning component 11 to move, and perform flatness detection on the building materials.

[0023] As Figure 3 shown, the detection component 10 includes a detection box 12 and a connecting rod 13. The detection box 12 is installed on one side of the installation plate 9. An activity cavity 14 is arranged in the detection box 12. A piston one 15 is movably arranged in the activity cavity 14. An air hole 16 is arranged on the bottom wall of the activity cavity 14. A column tube 17 is arranged on the top wall of the activity cavity 14. A piston two 18 is movably arranged in the column tube 17. The connecting rod 13 is connected to the bottom wall of the piston one 15. An observation window 22 is arranged on the detection box 12. A transparent plate 23 is arranged on the observation window 22. A scale marking 24 is arranged on the transparent plate 23. The scale marking 24 is arranged close to the column tube 17. The connecting rod 13 movably penetrates the bottom wall of the activity cavity 14 and is provided with a connecting frame 19. A spring 20 is arranged between the connecting frame 19 and the bottom wall of the detection box 12. A roller 21 is rotatably arranged on the connecting frame 19. After the roller 21 contacts the building materials, as the detection box 12 moves, when the roller 21 encounters concave and convex positions, it drives the connecting rod 13 to move. The connecting rod 13 drives the piston one 15 to move. The piston one 15 squeezes the liquid in the activity cavity 14 into the column tube 17. Since the volume of the liquid cannot be compressed, when the volume remains unchanged and the cross-section becomes smaller, the required length becomes longer. Thus, it can push the piston two 18 to move, thereby magnifying the undulation height of the building materials. Cooperating with the scale marking 24, it is convenient to observe the change of the flatness of the building materials.

[0024] As Figure 1 and 2 shown, the cleaning component 11 includes an air pump 25 and an air pipe 26. The air pump 25 is installed on the other side of the installation plate 9. The air pipe 26 is connected to the air pump 25. The end of the air pipe 26 is arranged close to both sides of the roller 21. Before detection, start the air pump 25 to compress the air and spray it through the air pipe 26, which can clean both sides of the moving wheel and reduce the influence of sundries on the monitoring results.

[0025] As Figure 1 and 2 shown, the pressing and positioning mechanism 3 includes a pressing plate 27 and a screw rod 28. The pressing plate 27 movably penetrates through both ends of the inspection table 1. The pressing plate 27 is arranged in a U shape. A cushion plate 29 is provided on the top wall of the pressing plate 27. The material of the cushion plate 29 is rubber. The screw rod 28 is rotatably arranged on the bottom wall of the inspection table 1. The screw rod 28 is threadedly connected to the pressing plate 27. When fixing the building materials, rotate the screw rod 28 to drive the pressing plate 27 to move downward, so that the pressing plate 27 drives the cushion plate 29 to move and press and fix the building materials. At the same time, since the cushion plate 29 has a certain buffering effect, it can avoid damaging the building materials.

[0026] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present invention, without creative design, structures and embodiments similar to the technical solution are all within the protection scope of the present invention.
