Description

Technical Field

[0001] The utility model belongs to the field of leveling structures, and in particular relates to a ground laying leveling structure. Background Art

[0002] Ground leveling is to make the original ground of the building reach the leveling standard through certain methods. Before laying wooden floors, the flatness of the ground must be ensured. The two common leveling methods are traditional cement mortar leveling and self-leveling leveling. The former uses ordinary cement mortar for leveling, while the latter uses high-polymer self-leveling cement for ground treatment.

[0003] A Chinese patent with publication number CN214942538U discloses a ground laying leveling structure. When a worker adjusts the height of an upper top seat, he only needs to hold a handle and rotate it, thereby rotating a rotating ring. Under the action of a threaded connection between the rotating ring and the threaded sleeve, and under the limiting action of an inner rod and an outer tube on the upper top seat, the threaded sleeve drives the upper top seat to move upward, thereby achieving height adjustment of the upper top seat. In this application, when a user pushes the rotating ring to rotate by means of a handle, the inner rod affects the user's hand to rotate around the lower base, thereby affecting the adjustment efficiency of the leveling structure.

[0004] In view of this, the present utility model is proposed. Utility Model Content
