Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a flatness detector. Background Art

[0002] Construction engineering covers the construction of houses and their ancillary facilities and the installation of supporting equipment, including electrical, water supply and drainage, etc. It requires multidisciplinary and professional collaboration, from design to construction, decoration and final acceptance to ensure the quality and safety of the building. Using a variety of materials and machinery, such as concrete, excavators, etc., construction engineering is a comprehensive engineering field.

[0003] The Chinese patent with publication number CN215865169U discloses a device for detecting the flatness of construction project quality. The device has a long extension range of a multi-stage hydraulic cylinder, which improves the telescopic space ratio of the supporting part and facilitates the telescopic movement of the supporting part. After adjusting the height, a motor is used to drive the second rotating wheel to roll on the lower plate, thereby driving the moving plate and the hanging plate to move. The first slider and the second slider are used to limit the moving posture of the hanging plate respectively, thereby reducing the lateral skewness of the hanging plate and improving the stability of use. The detection device body is driven to move by the mobile module, thereby realizing detection in the same area and reducing the number of movements, so as to achieve the effect of occupying a small space during transportation, facilitating movement and transportation, and facilitating adjustment of the height of the detector.

[0004] Although the above device has a certain telescopic ability, which can reduce the occupied space and facilitate movement and transportation, it still has a large volume after being retracted by the multi-stage hydraulic cylinder, which limits its convenience in movement and transportation. Utility Model Content

[0005] The utility model aims to provide a flatness detector which can reduce occupied space when not in use and improve convenience in movement and transportation.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A flatness detector includes a base and a detection device body. Two limit rods are installed inside the base along its length direction. A moving block is slidably installed on the outer surfaces of the two limit rods. A first threaded rod is rotatably installed inside the base along its length direction. The first threaded rod penetrates the inside of the moving block and is threadedly connected with it. A first motor is installed on the outer surface of the base. The output shaft of the first motor is connected to the first threaded rod. Side panels are installed on both sides of the upper surface of the moving block. A flip plate is rotatably installed between the two side panels. A lifting mechanism capable of driving the detection device body to rise and fall is arranged inside the flip plate. Two plug holes are provided on the outer surface of one of the side panels. The angle between the two plug holes is 90 degrees. A fixing mechanism capable of plugging and cooperating with the plug holes is arranged on the outer surface of the flip plate.

[0008] It can be seen that through the setting of structures such as the first motor and the first threaded rod, the detection device body can be driven to move horizontally, and through the setting of the lifting mechanism, the detection device body can be driven to move vertically, so that the wall can be tested for flatness in height and length directions, and through the setting of the fixing mechanism, the flip plate can be folded to a horizontal state and fixed, thereby greatly reducing the space occupied by the device and improving the convenience in movement and transportation.

[0009] Furthermore, the lifting mechanism includes a second threaded rod rotatably installed inside the flip plate, a nut seat is installed on the outer surface of the second threaded rod, and the detection device body is installed on the outer surface of the nut seat, the outer surface of the second threaded rod near the bottom is sleeved with a first bevel gear, and a second motor is installed on the outer surface of the flip plate, the end of the second motor output shaft passes through the interior of the flip plate and is installed with a second bevel gear, and the second bevel gear is meshingly connected with the first bevel gear.

[0010] Starting the second motor drives the second bevel gear to rotate. Since the second motor is meshed with the first bevel gear, it can drive the second threaded rod to rotate. The inner wall of the flip plate limits the nut seat, so that the nut seat can move along the length direction of the second threaded rod and drive the detection device body to rise and fall. The second motor is arranged on the bottom side, which can increase the weight of the bottom of the flip plate, making it more labor-saving when flipping the flip plate.

[0011] Furthermore, the fixing mechanism includes a fixing sleeve installed on the outer surface of the flip plate, a positioning rod is inserted into the interior of the fixing sleeve, and the positioning rod is plugged into the socket, a shoulder is provided on the outer surface of the positioning rod located at the lower side of the fixing sleeve, and a spring is sleeved on the outer surface of the positioning rod, and both ends of the spring are respectively abutted against the fixing sleeve and the shoulder.

[0012] When the flip plate is flipped to a vertical state, the positioning rod can be pulled out of the current socket first, and then the flip plate can be flipped. During the flipping process, the positioning rod can be loosened, and the end of the positioning rod can be driven to rest against the outer surface of the side plate under the push of the spring. Therefore, when the flip plate is flipped to a vertical state, the end of the positioning rod just corresponds to the other socket and is automatically inserted into it, so that the flip plate can be fixed. Similarly, when the device is not in use, the flip plate can be flipped to a horizontal state to reduce the occupied space.

[0013] Furthermore, support plates are rotatably mounted at both ends of both side surfaces in the width direction of the base, a third threaded rod is vertically penetrated through the interior of the support plate and threadedly connected, and an anti-skid pad is rotatably mounted at the bottom of the third threaded rod.

[0014] When the device is in use, in order to improve the overall stability, the support plate can be flipped outward and the device can be supported by the anti-skid pad, thereby improving the stability of the device; and when the ground is uneven, the height of the anti-skid pad can be adjusted by rotating the third threaded rod, so that the device can still maintain a horizontal state on the uneven ground, thereby improving the accuracy of detection.

[0015] Furthermore, a first magnet sheet is disposed on the outer surface of the support plate, and a second magnet sheet matched with the first magnet sheet is disposed on the outer surface of the base.

[0016] When the device is not in use, the support plate can be folded onto the side surface of the base to reduce the occupied space, and the support plate can be fixed to the side surface of the base through the adsorption effect of the first magnet sheet and the second magnet sheet, which is convenient for movement and transportation.

[0017] Furthermore, a handle is installed on the outer surface of the flip plate, and an anti-slip rubber sleeve is provided on the outer surface of the handle.

[0018] The setting of the handle makes it easy to flip the flip board, and the setting of the anti-slip rubber sleeve can increase the friction of the hand and reduce the situation of hand slipping. BRIEF DESCRIPTION OF THE DRAWINGS
