Description
Technical Field
[0001] The utility model relates to the field of measuring poles, in particular to a measuring pole for construction engineering. Background Art
[0002] Measuring poles are mostly measuring tools used in conjunction with levels. There are still certain problems when using measuring poles. For example, when using traditional measuring poles, due to its simple structure, it only has a single retractable pole body. When in use, it needs to be held by workers or inserted into the ground to stand upright. However, when the workers hold or insert the measuring pole into the ground, it is easy for the measuring pole to be unable to maintain a horizontal and vertical state due to force, resulting in deviations in measurement data during measurement. At the same time, the bottom of traditional measuring poles is generally conical and used to be inserted into the soil. However, sometimes the ground is cement or dry and hard soil, which will make it impossible to insert or difficult to insert, resulting in difficulty in fixing the measuring pole. Utility Model Content
[0003] The utility model aims to provide a benchmark for construction engineering measurement, which has the advantages of anti-tilting and convenient fixing.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A mounting seat is bolted to the surface of the connecting block, and there are four mounting seats. A rotating rod is rotatably connected to the inside of the mounting seat through a bearing. A supporting rod is fixedly sleeved on the surface of the rotating rod. An extension rod is arranged inside the supporting rod, and a fixing block is bolted to the bottom of the extension rod.
[0007] By adopting the above technical scheme, the utility model has a universal ball fixedly sleeved on the surface of the first set of rods. When the supporting rod lifts the connecting block, under the action of gravity, the first set of rods drives the universal ball to slide inside the universal groove, so that the first set of rods is in a horizontal vertical state. By screwing the second limit bolt to fix the universal ball, and then extending the second set of rods, the third set of rods and the fourth set of rods, the measuring benchmark can always be in a horizontal vertical state to ensure the accuracy of the measurement data. By installing four mounting seats on the connecting block, when the rotating rod inside the mounting seat is unfolded on the connecting block, the anti-slip pads on the four fixed blocks contact the ground to support them, and by using the extension rod, the distance between the fixed block and the mounting seat can be extended, so that the supporting area is enlarged, the stability of the support is improved, and the situation that the measuring benchmark is inconvenient to be fixed upright due to cement ground or dry and hard soil is prevented.
[0008] The utility model is further configured as follows: the first set of rods, the second set of rods and the third set of rods are all symmetrically bolted with sliders inside, and the second set of rods, the third set of rods and the fourth set of rods are all provided with sliding grooves used in conjunction with the sliders on their surfaces.
[0009] The above technical solution is adopted to facilitate the telescopic limiting of the second set of rods, the third set of rods and the fourth set of rods.
[0010] The utility model is further configured as follows: the surfaces of the first set of rods, the second set of rods and the third set of rods are all threadedly connected with first limit bolts, and the three first limit bolts are used in conjunction with the second set of rods, the third set of rods and the fourth set of rods respectively.
[0011] By adopting the above technical solution, the positions of the second set of rods, the third set of rods and the fourth set of rods are limited.
[0012] The utility model is further configured as follows: a second limit bolt is threadedly connected to the surface of the connection block, and one end of the second limit bolt penetrates into the interior of the universal groove and is used in conjunction with the universal ball.
[0013] The above technical solution is adopted to limit and fix the universal ball.
[0014] The utility model is further configured as follows: one end of the rotating rod penetrates the outside of the mounting seat and is threadedly connected to a limiting nut.
[0015] The above technical solution is adopted to limit the rotation of the rotating rod.
[0016] The utility model is further configured as follows: a guide block is symmetrically bolted inside the support rod, and a guide groove used in conjunction with the guide block is opened on the surface of the extension rod.
[0017] By adopting the above technical solution, the extension rod is slidably limited.
[0018] The utility model is further configured as follows: a third limit bolt is threadedly connected to the surface of the support rod, and the third limit bolt is used in conjunction with the extension rod.
[0019] By adopting the above technical solution, the position of the extension rod inside the support rod is limited.
[0020] The utility model is further configured as follows: an anti-skid pad is bolted to the bottom of the fixing block.
[0021] The above technical solution is adopted to improve the supporting friction with the ground.
[0022] In summary, the utility model has the following beneficial effects:
[0023] 1. The utility model has a universal ball fixedly sleeved on the surface of the first set of rods. When the support rod lifts the connecting block, the first set of rods drives the universal ball to slide inside the universal groove under the action of gravity, so that the first set of rods is in a horizontal vertical state. The universal ball is fixed and limited by twisting the second limit bolt, and then the second set of rods, the third set of rods and the fourth set of rods are extended, so that the measuring benchmark is always in a horizontal vertical state, ensuring the accuracy of the measurement data;
[0024] 2. The utility model has four mounting seats installed on the connecting block. When the rotating rod inside the mounting seat is unfolded on the connecting block, the anti-skid pads on the four fixed blocks contact the ground to support them. By using the extension rod, the distance between the fixed block and the mounting seat can be extended to increase the supporting area and improve the stability of the support, thereby preventing the situation in which the measuring benchmark is inconvenient to erect and fix due to cement ground or dry and hard soil.
