On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0037] The utility model provides a level measuring device for construction, which includes a device body 1, a measuring component for level measurement, and an adjusting mechanism 2 for adjusting the angle of the measuring component. A first installation cavity is provided inside the device body 1, the adjusting mechanism 2 is arranged in the first installation cavity of the device body 1, the measuring component is arranged outside the device body 1, and is connected to the adjusting mechanism 2. By adjusting the adjusting mechanism 2, the angle of the measuring component can be changed to achieve level measurement of a slope with an initial angle.

[0038] Embodiment 1:

[0039] The adjustment mechanism 2 includes a threaded rod 212, a threaded slider 213, a rack 215 and a gear 216. The threaded rod 212 is arranged along the length direction of the device body 1. The threaded slider 213 is sleeved on the threaded rod 212 and threadedly connected with the threaded rod 212. Both ends of the threaded rod 212 are fixed to the device body 1. A slide groove 214 is provided at the bottom of the first installation cavity. The slide groove 214 extends along the axial direction of the threaded rod 212. The bottom of the threaded slider 213 is slidably connected to the slide groove 214. A knob 211 for rotating the threaded rod 212 is provided on the outer wall of the device body 1. The end of the threaded rod 212 passes through the device body 1 and is fixedly connected to the knob 211.

[0040] The rack 215 is fixedly arranged on the top of the threaded slider 213, and the top of the rack 215 is provided with a plurality of teeth for meshing with the gear 216, and the gear 216 is meshed on the top of the rack 215. The two ends of the gear 216 are provided with connecting shafts, which pass through the device body 1 and are connected to the measuring component shaft.

[0041] The measuring assembly includes a rotating member 12, a level 13 and a scale line 11. The rotating member 12 is coaxially arranged with the gear 216. A recess for mounting the level 13 is provided in the middle of the rotating member 12. Both ends of the level 13 are fixed on the inner side walls opposite to each other in the recess.

[0042] The threaded rod 212 is rotated by the knob 211 to move the threaded slider 213 and the rack 215 on the top of the threaded slider 213. The rack 215 drives the gear 216 to rotate through the teeth meshing with the gear 216. The gear 216 drives the rotating member 12 to rotate, thereby achieving the angle adjustment of the level 13.

[0043] The scale lines 11 are arranged on the device body 1 along the circumference of the rotating member 12. The rotating member 12 is also provided with a pointer 14, and the position of the pointer 14 is arranged corresponding to the end of the level 13. When the user rotates the knob 211 to drive the rotating member 12 to rotate, the rotation angle can be confirmed by the pointer 14 on the rotating member 12 and the scale lines 11 on the device body 1.

[0044] Embodiment 2:

[0045] The outer wall of the device body 1 is detachably connected with a protective device, which is used to protect the level 13 to prevent the surface of the level 13 from absorbing dust and reducing the viewing clarity of the measurement data.

[0046] The protective device includes a protective cover 3 and a fixing box 31 for fixing the protective cover 3. The protective cover 3 is cylindrical. Connecting rods 35 for inserting into the fixing box 31 are provided on both sides of the protective cover 3. The protective cover 3 is made of transparent material for easy observation of the level meter 13 and the scale line 11.

[0047] A second installation cavity is provided in the fixing box 31 , and a limiting groove 36 for inserting the connecting rod 35 is provided on the side of the second installation cavity. A limiting assembly is provided inside the second installation cavity, and the connecting rod 35 inserted into the limiting groove 36 is fixed by the limiting assembly.

[0048] The limiting assembly includes a telescopic card rod 32 and a pull block 34 disposed in the second installation cavity. One end of the telescopic card rod 32 passes through the fixed box 31 and is fixedly connected to the pull block 34. A spring 33 is sleeved on the telescopic card rod 32. The spring 33 is located between the pull block 34 and the fixed box 31. One end of the spring 33 is fixedly connected to the fixed box 31, and the other end of the spring 33 is fixedly connected to the pull block 34. The telescopic card rod 32 forms a telescopic structure with the fixed box 31 through the spring 33 and the pull block 34. Under the action of the spring 33, the telescopic card rod 32 is always kept in the fixed box 31. The telescopic card rod 32 will continue to give pressure to the connecting rod 35 inserted into the fixed box 31, so that the insertion end of the connecting rod 35 is fixed in the fixed box 31, thereby fixing the protective cover 3.

[0049] Furthermore, the contact surface between the connecting rod 35 and the telescopic card rod 32 is provided with a slot with an inclined surface, and the end of the telescopic card rod 32 inserted into the slot is correspondingly provided with an inclined surface, which is conducive to the engagement between the connecting card rod 35 and the telescopic card rod 32, making the connection between the connecting card rod 35 and the telescopic card rod 32 more stable.

[0050] The working principle of the construction level measuring device of the utility model is as follows:

[0051] The initial angle of the level 13 on the device body 1 is 0°, that is, the position of the pointer 14 on the rotating member 12 points to the 0° position of the scale line 11 .

[0052] When measuring the levelness of a ground with a certain inclination angle (slope), firstly, according to the theoretical inclination angle of the ground, the knob 211 is turned to adjust the angle of the level 13 to the same as the theoretical inclination angle. The rotation angle of the level 13 can be confirmed by the pointer on the rotating member 12 and the scale line 11.

[0053] Then the device body 1 is placed on the ground, and whether the ground is flat and whether the actual tilt angle is correct is determined by observing the level meter 13. If the actual tilt angle of the ground is the same as the theoretical tilt angle, the level meter 13 should be in a horizontal position.

[0054] At the same time, when measuring the level of civil construction by means of a level measuring device, in order to improve the protective effect of the level 13 and prevent the surface of the level 13 from absorbing dust and reducing the clarity of the measurement data, a protective cover 3 can be inserted outside the measuring component to protect the protective cover 3.

[0055] The utility model provides a level measuring device for construction, which realizes angle adjustment of the measuring component by setting an adjustment mechanism 2 and a measuring component, so that the level measuring device can measure the level of the ground with a certain angle, thereby improving the measurement operation accuracy of the level meter 13.

[0056] The rotation adjustment of the rotating member 12 is realized by the combination of the threaded rod 212, the threaded slider 213, the rack 215 and the gear 216. The control of the angle adjustment is realized by the combination of the rotating member 12, the pointer 14 and the scale line 11.

[0057] By arranging a protective device on the outside of the measuring assembly, dust can be prevented from being adsorbed on the surface of the level meter 13, thereby reducing the viewing clarity of the measured data.

[0058] By combining the fixing box 31 and the limiting assembly, the dust cover 3 is fixed so that the dust cover 3 can be kept outside the measuring assembly, thereby improving the protection effect of the level meter 13.
