Detailed ways

In order to make the purpose and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1 and Figure 2, the utility model embodiment provides a kind of portable civil engineering construction measuring device, comprises level 4, top plate 20 and support bar 17, and described level 4 is arranged on the lower end of top plate 20, level 4 and top plate 20 are all arranged on the left side of the support rod 17, the center of the top plate 20 bottom surface is provided with a spherical hole 10, the straight rod 6 is fixedly installed on the top surface of the level 4, and a ball seat 7 is fixedly installed on the upper end of the straight rod 6, and the ball seat 7 is embedded in In the described spherical hole 10, a through hole 12 is vertically provided on the right side of the top plate 20, and a first screw rod 13 is arranged in the through hole 12, and the lower end of the first screw rod 13 extends to the outside along the opening of the lower end of the through hole 12, and is fixed laterally. A cross bar 9 is installed, the upper end of the first screw 13 extends to the outside along the opening of the upper end of the through hole 12, and a nut is threaded, the top plate 20 is fixed on the cross bar 9 by the nut, and a slide is fixedly installed on the right side of the cross bar 9. Block 8, a dovetail groove 16 is vertically arranged on the left side of the support rod 17, and the slider 8 is slidably installed in the dovetail groove 16, wherein the ball seat and the spherical hole are just like balls, and the friction between the two is reduced. Small, it will not affect the swing of the straight rod, so that the ball seat can rotate or swing freely in the spherical hole.

In this embodiment, the upper end of the slider 8 is horizontally provided with a first screw hole 15, and a second screw rod 14 is threaded in the first screw hole 15, and one end of the second screw rod 14 extends along the opening on the left side of the first screw hole 15 to Outside, and fixedly install a rotating block 19, the bottom surface of dovetail groove 16 is vertically provided with more than one second screw hole 18, and the second screw rod can be screwed in the second screw hole, thereby slide block is fixed in the dovetail groove.

In this embodiment, a fixed block 5 is fixedly installed on the bottom surface of the level 4, and a third screw hole 3 is provided on the bottom surface of the fixed block 5, and a third screw 2 is threaded in the third screw hole 3, and the lower end of the third screw 2 is fixedly installed. A weight 1, the weight can be a metal material.

In this embodiment, a handle 11 is fixedly installed on the surface of the top plate 20, and the level is moved conveniently through the handle.

In this embodiment, a tripod (not shown) is fixedly installed at the lower end of the support rod 17, and the tripod only needs to enable the support rod to be placed on the ground.

In this embodiment, a scale (not shown) is arranged vertically on the right side of the support rod 17, which is convenient for grasping the distance when the level moves.

Working principle: Since the level is movably connected to the top plate through the ball seat, when in use, the heavy object is screwed to the lower end of the level. After releasing the heavy object, the level will swing with the swing of the heavy object. When the heavy object stops swinging, The straight rod will be perpendicular to the ground, and the level fixed on the straight rod will be perpendicular to the ground, so that no matter which direction the support rod is tilted, the level will always be perpendicular to the ground, which facilitates leveling and increases work efficiency. Under the action of heavy objects, the outside breeze cannot blow to the level, which increases the stability. The level can be pulled up and down along the chute through the handle. After the height is determined, turn the rotating block, and the rotation of the rotating block drives the second screw. One end of the second screw rod is screwed into the second screw hole, thereby effectively fixing the slider and avoiding the displacement of the slider.
