Description

Technical Field

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

[0002] When carrying out construction projects, buildings are often inspected after construction, and parallelism inspection is also one of the most common inspections. Parallelism refers to the degree of parallelism of two building planes. If the parallelism differs too much, it is easy to lead to insufficient support stability of the building, and it is not convenient for subsequent accurate construction. For example, the patent with publication number CN219956394U discloses a parallelism detection device for engineering buildings, including an outer rod, an inner rod is slidably connected to the inner rod inside the outer rod, a gasket is fixedly connected to one side of the inner rod, a slide is fixedly connected to one side of the gasket by a fixing bolt, two sliders are slidably connected to the inner side of the slide, a connecting plate is fixedly connected to the top of the slider, a clamping plate is fixedly connected to one side of the connecting plate, a sliding rod is slidably connected to the inner side of the clamping plate, a limiting plate is fixedly connected to one side of the sliding rod, and a block is fixedly connected to the other side of the sliding rod. The device is configured with an outer rod and an inner rod, by sliding the inner rod to a suitable height and tightening the bolts on the surface of the outer rod to fix the outer rod and the inner rod, so that the device can be adjusted to a suitable height, thereby facilitating the detection of buildings of different heights. However, the device cannot directly display the angle between two non-parallel buildings and can only detect whether the two buildings are parallel, resulting in low accuracy.

[0003] To this end, the utility model provides a parallelism detection device. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a parallelism detection device, including a support frame 1, the support frame 1 includes two telescopic rods, a detection structure is installed between the two telescopic rods, the detection structure includes a detection rod 7 and two sliding rods 8, the sliding rod 8 is slidably connected to the detection rod 7, the sliding rod 8 is rotatably connected to the telescopic rod, a sliding shaft 9 is slidably fitted on the sliding rod 8, one end of the sliding shaft 9 is equipped with a detection head 12, one side of the detection rod 7 is rotatably fitted with a detection disk 17 and a pointer 18, and the two detection heads 12 correspond to the detection disk 17 and the pointer 18 respectively.

[0022] In this embodiment, the telescopic rod includes a first rod body 2 and a second rod body 3 , which are slidably connected to each other. A plurality of positioning bolts 4 are installed on the first rod body 2 , and the positioning bolts 4 correspond to the second rod body 3 .

[0023] Specifically, the height of the device can be adjusted by sliding the second rod 3 upwards, and the second rod 3 can be fixed by the positioning bolt 4, so as to facilitate the inspection of higher buildings.

[0024] A rotating frame 5 is fixed to one end of the second rod body 3, and a first rotating shaft 6 is fixed to the sliding rod 8. The first rotating shaft 6 is rotatably connected to the rotating frame 5. A damping block is installed between the first rotating shaft 6 and the rotating frame 5. The first rotating shaft 6 and the rotating frame 5 can be fixed by damping.

[0025] Specifically, the detection rod 7 and the sliding rod 8 can be rotated by the first rotating shaft 6, thereby driving the detection head 12, the detection disk 17 and the pointer 18 to rotate, thereby ensuring that the detection head 12 is in contact with the building, thereby ensuring the detection effect and expanding the scope of application of the device.

[0026] A through slot 10 is provided in the sliding rod 8, and the through slot 10 corresponds to the sliding shaft 9. A fixing bolt 11 is threaded on the sliding rod 8, and the fixing bolt 11 corresponds to the sliding shaft 9. A groove 22 is provided in the detection head 12, and a pressure plate 13 is installed in the groove 22. A spring 14 is fixed between the pressure plate 13 and the groove wall of the groove 22. A first electrode piece 15 is fixed in the groove 22, and a second electrode piece 16 is fixed on the pressure plate 13. The first electrode piece 15 corresponds to the second electrode piece 16. A second rotating shaft 21 is fixed on one side of the detection rod 7, and an indicator light 20 is fixed on the second rotating shaft 21. The indicator light 20 is connected to the first electrode piece 15 and the second electrode piece 16 by an electric wire. The second rotating shaft 21 is rotatably connected to the detection disk 17 and the pointer 18. A torsion spring is installed between the rotating shaft 21 and the detection disk 17 and the pointer 18. A pull rope 19 is fixed between the two detection heads 12 and the detection disk 17 and the pointer 18 respectively.

[0027] Specifically, when performing detection, the sliding shaft 9 can be pushed so that the sliding shaft 9 pushes the detection head 12 to move. When the lengths pushed by the two sliding shafts 9 are the same, if one of the detection heads 12 is in contact with the building and the other detection head 12 is not in contact with the building, the two are not parallel. At this time, the pressure plate 13 in contact with the building is squeezed, so that the first electrode sheet 15 contacts the second electrode sheet 16, so that the indicator light 20 lights up, and then the detection disk 17 that is not in contact with the building is pushed alone, so that the detection disk 17 pulls the detection disk 17 or the pointer 18 alone through the pull rope, so that the angle between the two can be directly displayed.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
