Detailed Description

In order that those skilled in the art will better understand the present utility model, the following technical scheme of the present utility model will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1 to 4, the alignment frame of the leveling instrument comprises a support 1 and a leveling instrument 2, wherein the support 1 is provided with a spherical cavity 3, the lower side of the support 1 is provided with a limit groove 4, a sphere 5 is installed in the spherical cavity 3 in a matched mode, the upper end and the lower end of the sphere 5 are symmetrically connected with connecting rods 6, the connecting rods 6 positioned on the upper side of the sphere 5 are connected with the bottom end of the leveling instrument 2, the limit groove 4 is in sliding fit with a lifting plate 7, the lifting plate 7 is provided with a screw 8 which is threaded with the support 1, the lifting plate 7 is provided with an avoidance opening 9, the connecting rods 6 positioned on the lower side of the sphere 5 are positioned in the avoidance opening 9, the support 1 is provided with a plurality of through holes 10 communicated with the spherical cavity 3, the lifting plate 7 is connected with a collision rod 11 positioned in the through holes 10, and the end part of the collision rod 11 is provided with a cambered surface 12 with the radian matched sphere 5.

In this embodiment, when an alignment frame of a level is used, after the bracket 1 is placed on a placement surface, if the angle of the level 2 needs to be adjusted, the screw 8 is loosened, so that the lifting plate 7 moves downwards, the lifting plate 7 descends stably under the effect of the limit groove 4, the lifting plate 7 moves downwards, the abutting rod 11 installed on the lifting plate 7 moves downwards, the cambered surface 12 is separated from the fixation of the sphere 5, at this time, the connecting rod 6 on the lower side of the sphere 5 is stirred to realize the movement of the corresponding connecting rod 6 on the upper side of the sphere 5, and under the characteristic of the sphere 5, the level 2 can realize the adjustment of the corresponding angle direction, so as to achieve the purpose of quick adjustment; after the position is determined, the locking screw 8 drives the lifting plate 7 to move upwards, so that the purpose that the cambered surface 12 contacts the sphere 5 to fix the sphere 5 under the effect of friction force is achieved, and the fixing effect is enhanced due to the arrangement of the plurality of contact resisting rods 11.
