Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a flatness detection device for assembled buildings. Background Art

[0002] Prefabricated buildings are structures that shift much of the traditional on-site construction work to the factory. Components and accessories (such as floor slabs, wall panels, stairs, and balconies) are manufactured in the factory, transported to the construction site, and assembled and installed on-site using reliable connections. Prefabricated buildings require testing for flatness after assembly, requiring specialized flatness testing equipment.

[0003] A Chinese utility model patent with the announcement number CN221649433U discloses a construction engineering flatness detection device. The device drives a lead screw to rotate forward through a motor, and the forward rotation of the lead screw drives a movable seat to move to the left. The movable seat drives a detection box to move to the left through a moving rod, and the detection wheel begins to roll left along the wall. When the wall surface becomes uneven, the position of the movable plate in the detection box will change. The distance sensor detects the position fluctuation of the movable plate, and the detection result is displayed on the display screen. After the detection is completed, the staff can analyze and judge the specific situation of the wall flatness based on the data on the display screen. This effectively improves the accuracy of the detection results. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] In actual use, although the device can accurately detect the flatness of the building, it lacks an integrated structure that can automatically mark the concave and convex positions, making it inconvenient for staff to subsequently find and repair the concave and convex positions, thereby reducing the practicality of the device. For this reason, we provide a flatness detection device for prefabricated buildings. Utility Model Content

[0008] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0009] As a further improvement of the above solution, guide blocks are fixedly connected to both sides of the upper part of the movable column, and guide grooves are provided on the frame at positions corresponding to the guide blocks and are slidably connected to the guide blocks.

[0010] As a further improvement of the above solution, both ends of the spring are fixedly connected to the inner cavity top and the limiting plate respectively.

[0011] As a further improvement of the above solution, the bottom of the inner cavity of the storage box is designed as a funnel-shaped structure.

[0012] As a further improvement of the above solution, a valve is provided on the discharge pipe.

[0014] As a further improvement of the above solution, both sides of the frame are fixedly connected with support frames, and the support frames are fixedly connected with counterweight blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model drives the screw rod to rotate through the motor, so that it can drive the moving column to move, and the movement of the moving column can drive the vertical rod to move, thereby driving the roller and the marking pen to move together. At the same time, by utilizing the movable cooperation between the limit plate and the cavity and the elastic effect of the spring itself, when the roller encounters a concave and convex surface during the rolling process, it can automatically move vertically, thereby driving the marking pen to move vertically together.

[0027] Please combine Figure 1-5 , a flatness detection device for an assembled building in this embodiment includes:

[0028] A frame 1 is rotatably connected to a screw rod 2, one side of the frame 1 is fixedly connected to a motor, and the end of the motor's rotor is coaxially fixedly connected to one end of the screw rod 2;

[0029] The marking detection component includes a moving column 101 which is threadedly connected to the outside of the screw rod 2. A cavity is opened at the lower part of the moving column 101, and the interior of the cavity is movably connected to a limit plate 102. A spring 103 is also provided inside the cavity. The two ends of the spring 103 are respectively fixedly connected to the top of the inner cavity of the cavity and the limit plate 102. The bottom of the limit plate 102 is fixedly connected to a vertical rod 104 and the bottom end of the vertical rod 104 extends to the outside of the cavity. The bottom end of the vertical rod 104 is rotatably connected to a roller 105. A storage box 106 is fixedly connected to the outside of one side of the moving column 101.

A baffle 108 is provided on the outside of the nozzle of the discharge pipe 107. A horizontal plate 109 is fixedly connected to the baffle 108 through a bracket and One end of the horizontal plate 109 extends to the interior of the cavity and is slidably connected to the cavity wall. A connecting rod 110 is hinged between the horizontal plate 109 and the vertical rod 104 through a hinge. The external fixed sleeve of the vertical rod 104 is provided with a ring, and a marking pen 111 is fixedly connected to the ring. A marking plate 112 is fixedly connected to one side of the bottom of the frame 1. Guide blocks 3 are fixedly connected to both sides of the upper part of the moving column 101. A guide groove is provided at the position corresponding to the guide block 3 on the frame 1 and is slidably connected to the guide block 3, which can play a certain guiding role in the horizontal movement of the moving column 101. The bottom of the inner cavity of the storage box 106 is designed as a funnel-shaped structure, which is convenient for the rapid discharge of the marking powder to prevent residue.
