Description

Technical Field

[0001] The utility model relates to the technical field of angle measurement, in particular to an angle measurement device used for steel structure detection. Background Art

[0002] Steel structures are characterized by high strength, light weight, good overall rigidity and strong resistance to deformation. Therefore, they are particularly suitable for building large-span, ultra-high and ultra-heavy buildings. During the use of steel structures, their welding angles, cutting angles or installation angles need to be measured.

[0003] Some existing devices generally open the measuring angle bar 1 and the measuring angle bar 2 to a certain angle by turning a knob, and then the measuring head can be placed against the steel structure to be measured to measure the weld angle. The measuring device for the weld angle of the building steel structure has the advantage of being easy to measure, so that the measuring head can adapt to various narrow gaps and measure accurately, thereby improving the application range of the measuring device. In addition, through the coordinated use of a bidirectional screw rod, a screw sleeve, a hollow frame, a movable block and a connecting rod, the measuring angle bar 1 and the measuring angle bar 2 can be opened to a certain angle for measurement.

[0004] However, in actual use, when the above-mentioned equipment is used to detect some places with smaller installation angles, its measuring bar may not be able to touch the installation location, which may cause deviation in the measurement angle; in view of this, we propose an angle measurement device for steel structure detection. Utility Model Content

[0005] The purpose of the utility model is to provide an angle measuring device for steel structure detection to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an angle measuring device for steel structure detection, comprising a measuring rod, a measuring table is arranged on the front of the measuring rod, an auxiliary rod is rotatably connected to the back of the measuring rod near the measuring table, a placement groove is provided on the back of the measuring rod away from the measuring table, an embedding groove is provided on the front of the measuring rod near the placement groove, an installation groove is provided on the back of the auxiliary rod away from the measuring table, a connecting rod is rotatably connected to one side of the inner wall of the placement groove, a fixing rod is rotatably connected to one side of the inner wall of the installation groove, and a fixing groove is provided on one side of the inner wall of the installation groove. An embedded block is fixedly connected to one side of the connecting rod, and a fixed block is fixedly connected to the top of the fixing rod. A supporting structure is provided at the bottom of the inner wall of the mounting groove, and the supporting structure includes a slide groove. A slide groove is provided at the bottom of the inner wall of the mounting groove, and a slider is clamped inside the slide groove. A limiting groove is provided on one side of the inner wall of the slide groove near the fixed groove, and a support rod is hinged on the top of the slider. A protrusion is provided on one side of the slider, and the size of the protrusion is adapted to the size of the limiting groove. A storage groove is provided on the side of the fixing rod near the mounting groove, and a supporting structure is also provided on the side of the connecting rod near the placement groove.

[0007] Preferably, the fixing block is convexly arranged, the position of the fixing block corresponds to the position of the fixing groove, and the size of the fixing block is adapted to the size of the fixing groove, which can enable the fixing block to be well inserted into the fixing groove.

[0008] Preferably, the position of the embedding block corresponds to the position of the embedding groove, and the size of the embedding block matches the size of the embedding groove, which can enable the embedding block to accurately slide into the embedding groove.

[0009] Preferably, the size of the support rod is matched with the size of the storage slot, and the position of the placement slot corresponds to the position of the installation slot, which can make the positions of the connecting rod and the fixing rod relative to each other and make it more convenient to measure the angle.

[0010] Preferably, a groove is provided at one end of the auxiliary rod, a spring is fixedly connected to one side of the inner wall of the groove, an internal thread is provided on the arc-shaped inner wall of the groove, a baffle is fixedly connected to one end of the spring, an extension rod is provided on one side of the baffle, and an external thread is provided on the arc-shaped surface of the extension rod.

[0011] Preferably, the internal thread corresponds to the external thread, and the internal thread meshes with the external thread, and the size of the extension rod matches the size of the groove.

[0012] Compared with the prior art, the utility model provides an angle measuring device for steel structure detection, which has the following beneficial effects:

[0013] 1. In order to avoid measurement deviation when measuring places with smaller installation angles, the angle measuring equipment used for steel structure detection takes out the connecting rod and the fixing rod from the placement slot and the installation slot respectively when measuring places with smaller angles, so that the connecting rod and the measuring rod are set at right angles, and the fixing rod and the auxiliary rod are set at right angles. In this way, the connecting rod and the fixing rod can be extended to places with smaller angles for detection. At the same time, the slider is slid to one side of the inner wall of the slide slot close to the fixing slot, and the slider is embedded in the limit slot. In this way, the support rod supports the fixing rod, so that the fixing rod is not easy to slide and cause deviation in the measurement data. Similarly, a support rod is also provided on one side of the connecting rod to support the connecting rod. In this way, the equipment is not easy to cause deviation when measuring places with smaller angles.

[0014] 2. In order to prevent the device from being unable to adapt to different measurement scenarios, the measuring rod and the auxiliary rod are both provided with extension rods at the ends away from the measuring table. When in use, the external thread provided on the outer surface of the extension rod engages with the internal thread provided on the inner wall of the groove, so that the extension rod is limited inside the groove. The extension rod is rotated to extend out of the groove, so that the elastic force of the spring pops the extension rod out of the groove and allows the extension rod to be extended faster. In this way, the measuring rod and the auxiliary rod can be extended to better adapt to the needs of different scenarios for measurement. BRIEF DESCRIPTION OF THE DRAWINGS
