Technical Field

[0001] The utility model relates to the technical field of level instruments, in particular to a level instrument for municipal road construction. Background Art

[0002] Municipal road construction is a vital part of urban infrastructure construction. It is not only directly related to the smooth traffic on urban roads, but also to the travel safety and quality of life of citizens. In the process of municipal road construction, the level plays an important role. It is mainly used to ensure the levelness and flatness of roads, bridges and other buildings. By using the level, construction workers can accurately measure and adjust the level of the road surface to ensure the flatness of the road and avoid improper slopes or unevenness, thereby improving the comfort and safety of the road.

[0003] At present, the angle fixing effect of the tripod support part of the ordinary municipal road construction level on the market is poor when in use. It is easily affected by the gravity of the instrument or the influence of the moving device, causing the support angle to change. It is often necessary to readjust the angle of the support many times, which is not convenient to use and may even seriously affect the measurement work of the instrument. In addition, the support part is difficult to adjust according to the terrain conditions, resulting in the tilt of the level itself. In addition, the level sometimes needs to be rotated horizontally when in use in order to detect the horizontal state of other directions. However, the ordinary level lacks fixation after the lateral angle is rotated, and the level is easily affected by external forces and rotated at will.

Figure 1 and attached Figure 3 As shown, the position of the ring sleeve 11 is fixed more firmly.

[0025] Further, three groups of connecting rods 7 are provided, and the three groups of connecting rods 7 are equidistantly distributed in a circular axis array manner. One end of the connecting rod 7 is hingedly connected to the lower end of the first telescopic rod 2. Figure 1As shown, the connecting rod 7 can push the first telescopic rod 2 to rotate when following the movement of the fixing plate 12, so that the rotation angle of the first telescopic rod 2 can be adjusted.

[0026] Furthermore, multiple groups of threaded holes 10 are provided, and the multiple groups of threaded holes 10 are equidistantly distributed at one side of the bottom of the first telescopic rod 2 in a linear array manner. The threaded holes 10 are adapted to the fastening screws 9, and one end of the fastening screws 9 passes through the top thread of the second telescopic rod 3 and is inserted into the inside of the threaded holes 10.

[0029] Working principle: When using, first place the device on a relatively flat ground, then slide the ring sleeve 11 along the outer surface of the screw rod 5. When the ring sleeve 11 gradually slides down, the ring sleeve 11 drives the fixed plate 12 to slide down, and the fixed plate 12 drives the connecting rod 7 to move. The two ends of the return spring 17 are hinged and rotated between the bottom of the first telescopic rod 2 and the fixed plate 12, and at the same time, push the first telescopic rod 2, so that the bottom of the first telescopic rod 2 rotates away from the screw rod 5. The greater the expansion angle of the first telescopic rod 2, the lower the height of the main platform 1. When the main platform 1 is at a suitable height position, stop sliding the ring sleeve 11, and then follow the outer thread of the screw 5. The position of the ring sleeve 11 can be limited by rotating the two sets of tightening screw sleeves 6 so that they are respectively tightly attached to the top and bottom ends of the ring sleeve 11. Then, pull the second telescopic rod 3 according to the indication on the bubble level 15 so that the anti-slip foot pads 4 are in contact with the ground and the bubble in the bubble level 15 is in the middle position of the bubble level 15. Then, insert the fastening screw 9 through the second telescopic rod 3 into a set of threaded holes 10 at appropriate positions and tighten it. Then, place the external level instrument in the middle of the supporting turntable 8, and turn the push bolt 13 to make the rubber surface splint 14 tightly attached to the outside of the external level instrument.

[0030] When the lateral angle of the external horizontal instrument needs to be adjusted, the moving block 16 can be pressed downward first to compress the reset spring 17. When the plug-in column at one end of the moving block 16 slides out of the socket at the bottom of the supporting turntable 8, the supporting turntable 8 can be directly rotated, so that the rotating shaft 18 rotates in the middle of the main platform body 1, driving the supporting turntable 8 to rotate smoothly. After the supporting turntable 8 drives the external horizontal instrument to rotate to a suitable angle, the moving block 16 can be released. Under the rebound of the reset spring 17, the plug-in column at one end of the moving block 16 slides into a group of sockets at the bottom of the supporting turntable 8 at a suitable position to fix the lateral rotation angle of the supporting turntable 8. The above is the entire working principle of the utility model.
