Background

The leveling rod is an important measuring tool for measuring the ground elevation, but can be influenced by various factors such as wind, vibration and the like during the use, and the factors can influence the reading accuracy of the leveling rod. In order to improve the measurement accuracy of the leveling rod, the leveling rod auxiliary device may be used for measurement. Level gauge measurement is one of the most basic and common measurement works in the current engineering measurement work.

Examples: novel leveling rod is measured and is assisted device

As shown in fig. 1-5, a novel leveling rod measurement auxiliary device comprises the following specific structures:

the inner base 1, annular spout 2 has been seted up to the top surface of base 1, the both sides of spout 2 respectively sliding fit installs curved slider 3, the common fixed mounting rotary platform 4 of upper end of slider 3, the both sides fixed mounting of rotary platform 4 top surface has a plurality of symmetrical support 5 that set up, screw rod fixation clamp 6 is installed respectively to the upper end of support 5, two screw rod fixation clamp 6 symmetry sets up.

The center of the top surface of the base 1 is provided with a groove 7, an annular gear 8 is fixedly arranged in the groove 7, a rotating shaft 9 is rotatably arranged at the eccentric position of the bottom surface of the rotating platform 4 through a damping bearing, and a gear 10 meshed with the annular gear 8 is fixedly arranged at the lower end of the rotating shaft 9. The gear 10 and the inner gear ring 8 are meshed with each other, when a user rotates the rotary platform 4, the gear 10 can play a limiting role on the rotary platform 4, so that the stability of the rotary platform 4 is improved, and the gear 10 can be prevented from rotating under the action of damping of a damping bearing at the joint of the rotating shaft 9 and the rotary platform 4 without other external force, so that the rotary platform 4 can stay at any rotation angle, and the using effect of the device is improved.
