The azimuth holding component in the embodiment of the disclosure supports and limits a plurality of dimensions of the leveling substrate 2 in the horizontal direction, so as to limit the leveling substrate 2 to rotate in the horizontal direction, thereby ensuring that the azimuth angle of the azimuth holding component is always kept unchanged in the process of adjusting the leveling substrate 2, the azimuth holding component can adopt a supporting and limiting structure such as a strip, a block, a ball, an L shape and the like, and the number of the azimuth holding components can be determined according to the shape of the leveling substrate 2 and the shape of the azimuth holding component.

In some embodiments of the present disclosure, the base 1 may be provided with a chute that provides at least one of the azimuth holding assemblies to be displaced along a straight line, so as to enable the azimuth holding assembly to meet the clamping of the leveling base plate 2 with different specifications. Specifically, the displacement direction of the chute is a linear direction in which the azimuth holding assembly is made to be close to or away from the leveling base plate 2, and the azimuth holding assembly may be fixed at a target position of the chute by clamping, bolting, or other means.

In some disclosed embodiments, the orientation maintaining assembly may include at least: 1 azimuth adjuster 4a having elastic deformation amount and 2 azimuth holders 4b having no elastic deformation amount; the azimuth adjuster 4a is abutted against one side of the leveling base plate 2, the 2 azimuth retainers 4b are abutted against the opposite side of the leveling base plate 2, and the force application points of the three on the leveling base plate 2 form an isosceles triangle supporting structure taking the azimuth adjuster 4a as a vertex angle. That is, 2 azimuth holders 4b are on the same straight line, and the azimuth adjuster 4a is located on the middle vertical line between the azimuth holders 4 b.

In the embodiment, 1 azimuth adjuster 4a with elastic deformation quantity is arranged on one side of the leveling substrate 2, and 2 azimuth retainers 4b without elastic deformation quantity are arranged on the other opposite side of the leveling substrate, and the azimuth adjuster 4a with elastic deformation quantity and the azimuth retainers 4b can keep certain limiting pressure on the leveling substrate 2, so that the limiting capacity of the leveling substrate 2 is ensured; on the other hand, the assembly and adjustment of the leveling substrate are also facilitated, and the problems of rigid friction, part damage and reliability and precision reduction in the assembly and adjustment process are avoided. And the isosceles triangle supporting structure is formed by the azimuth adjuster and the azimuth retainer, which is also beneficial to self-balancing of the leveling substrate.

It will be appreciated by those skilled in the art that a rigid retaining structure may be employed without the orientation adjuster having an elastic deformation amount, but a small degree of coordinated adjustment is required during adjustment, so that the problem of rigid friction is avoided.

In some disclosed embodiments, the azimuth adjuster 4a may include: an adjustable ball seat 411, in which a first rolling ball 412 and a spring (not shown) for supporting the first rolling ball 412 to be deformed in a linear expansion are provided (shielded by the adjustable ball seat 411); the spherical surface of one side of the first rolling ball head 412 far away from the spring is exposed out of the adjustable ball head seat 411 and is propped against the side surface of the leveling substrate 2.

Preferably, the rolling ball heads of the azimuth adjuster 4a and the azimuth retainer 4b are of equal-height structures on the base 1, so that contact points of the azimuth adjuster 4a and the azimuth retainer 4b with the leveling base plate 2 are located at the same horizontal plane as much as possible, and the stress balance of the leveling base plate 2 is ensured.

Before adjustment, the two second rolling balls 422 of the 2 azimuth holders 4b are firstly respectively contacted with the same side face of the leveling base plate 2, and the two contact points are used as an azimuth line which can be determined by presetting the relative positions of the two azimuth holders 4 b. The first rolling ball 412 of the azimuth adjuster 4a is contacted with the opposite side of the leveling base plate 2, and due to the spring in the first rolling ball 412, the first rolling ball 412 can move back and forth along the adjustable ball seat 411 and has a certain pre-pressure, the first rolling ball 412 is automatically adjusted by the lateral component force during leveling, the other 2 second rolling balls 422 are matched to always keep three lateral points of the leveling base plate 2 in contact, an isosceles triangle is formed, and meanwhile, the two second rolling balls 422 are identical to the stress points on the side surface of the leveling base plate 2, so that better gesture stability is provided. In the leveling process, the 2 second rolling balls 422 are always tangent to the side face of the leveling base plate 2, namely, the azimuth line is always coincident with the side edge of the leveling base plate 2, so that the azimuth angle of the leveling base plate 2 is not changed in the adjusting process.

In some embodiments of the present disclosure, the azimuth adjuster 4a and the azimuth retainer 4b may be fixed to the base 1 by bolts, but may be fixed by clamping, bonding, or the like.

When the leveling device is used, the locking screw is twisted, the adjusting state of the leveling bolt is opened, and then the leveling bolt is fastened by twisting the locking screw after the leveling purpose is achieved by adjusting the leveling bolt, so that the leveling bolt is prevented from loosening.

Although the leveling bolt assembly 3 also has a certain height adjusting function, the leveling bolt assembly is essentially used for leveling, the accuracy of adjusting the height of the leveling bolt assembly is seriously dependent on personnel experience, the target height of the leveling base plate 2 is set by adopting the height adjusting ball head 5 in the embodiment of the disclosure, and the leveling bolt assembly 3 is used for adjusting the height. Preferably, the height adjustment ball 5 may be a ball stud.

Further, a groove for accommodating the spherical surface is formed in the position of the leveling base plate 2 relative to the height adjusting ball head 5, so that the influence on the height adjusting range of the leveling base plate can be avoided.

Preferably, the height adjusting ball 5 in the embodiment of the present disclosure may be disposed around one of the leveling bolt assemblies 3 to support the leveling base plate 2 instead of the leveling bolt assembly 3 before leveling is completed.

When the leveling bolt assembly is used, the height adjustment ball head 5 can be utilized to set the target height to replace the leveling bolt assembly 3 at the body side to be propped against the base 1, and the height error is much smaller than that of a planar bolt due to spherical tangent contact, so that the height adjustment precision can be effectively improved. And then the adjustment of pitch angle and roll angle is completed by sequentially adjusting other leveling bolt assemblies 3, so that the leveling function is realized. And then the leveling bolt component 3 replaced by the height adjusting ball head 5 is completely abutted against the base 1, and the height adjusting ball head 5 is separated from the base 1.

The structure, assembly and use method of the leveling base plate 2, the leveling bolt assembly 3, the azimuth adjuster 4a, the azimuth retainer 4b and the height adjustment ball 5 in this embodiment can refer to the above embodiment, and will not be described herein.

When the leveling device is used, firstly, one leveling bolt assembly 3 closest to the height adjusting ball head 5 is separated from the base 1, then the height adjusting ball head 5 is used for contacting the base 1, the target height is set, and then the other two leveling bolt assemblies 3 are adjusted based on the target height, so that the pitch angle and the roll angle of the leveling substrate 2 are adjusted until leveling is achieved, and the two leveling bolt assemblies 3 are locked; and then the unadjusted leveling bolt assembly 3 is completely contacted with the base 1, and after locking, the height adjusting ball head 5 is separated from the base 1, so that the adjustment of the height, the pitch angle and the roll angle is completed, and in the process, the azimuth angle of the leveling substrate 2 is ensured to be unchanged due to the interaction of the azimuth adjuster 4a and the azimuth retainer 4 b.
