It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be arbitrarily combined with each other.
[0038] As described in the above background art, for the structures on the aircraft with relative position installation requirements, there are usage requirements for the installation supports for installing products with position adjustment. In the existing position adjustment solutions of the supports, since the position adjustment is achieved by increasing or decreasing gaskets in one direction according to the installation requirements, it leads to complex adjustment construction processes, and the gaskets are prone to wear, resulting in functional failure or performance degradation.
[0039] In view of the above problems, the embodiments of the present utility model provide a support assembly with a two-way position adjustment function. This support assembly does not use gaskets for position adjustment. By providing a toothed plate fixedly connected to the installation base body, and partitioning the outer end face of the toothed plate, one adjustment area is provided with long teeth along the first direction, and the other adjustment area is provided with long teeth along the second direction. Long teeth in two directions corresponding to the toothed plate are provided on the bottom surface of the support installation surface. Through the cooperation of the long teeth in two directions, the position adjustment of the support in two directions on the installation base body is realized, thus avoiding the occurrence of functional failure or performance degradation caused by gasket wear.
[0040] The present utility model provides several specific embodiments that can be combined with each other. For the same or similar concepts or processes, they may not be repeated in some embodiments.

Referring to Figure 1 and Figure 2 shown, the overall structure of the support assembly with a two-way position adjustment function provided by the embodiments of the present utility model includes: a base body 1, a two-way adjustment toothed plate 2 and a support 3.
[0042] As Figure 1 and Figure 2 shown, the two-way adjustment tooth plate 2 in the embodiment of the present utility model is fixedly installed on one side end face of the base body 1. A first groove penetrating its symmetry axis is provided on the outer end face of the two-way adjustment tooth plate 2. The two-way adjustment tooth plate 2 is divided into two adjustment regions through this first groove; the first adjustment region is provided with long teeth along the first direction, and the second adjustment region is provided with long teeth along the second direction, and the second direction is perpendicular to the first direction. It should be noted that the first groove on the outer end face of the two-way adjustment tooth plate 2 serves as a tool withdrawal groove for machining the long teeth on the two-way adjustment tooth plate 2. As Figure 3 shown, for Figure 1 the structural schematic diagram of the outer end face of the two-way adjustment tooth plate in the support assembly with two-way position adjustment function provided by the embodiment shown, Figure 3 the directions of the long teeth in the two adjustment regions are schematically shown.

The end face of the support 3 is divided into two adjustment regions through the second groove; the third adjustment region is provided with long teeth along the first direction, and the fourth adjustment region is provided with long teeth along the second direction. It should be noted that the second groove on the inner end face of the support 3 serves as a tool withdrawal groove for machining the long teeth on the inner side of the support 3. As Figure 6 shown, for Figure 1 the structural schematic diagram of the outer end face of the support in the support assembly with two-way position adjustment function provided by the embodiment shown, Figure 6 the directions of the long teeth in the two adjustment regions of the end face of the support 3 are schematically shown; and Figure 6 the directions of the long teeth in the two adjustment regions of the end face of the support 3 in Figure 3 correspond to the directions of the long teeth in the two adjustment regions of the end face of the two-way adjustment tooth plate 2.
[0044] Based on the mating structure machined on the opposite end faces of the above two-way adjustment tooth plate 2 and the support 3, after the support 3 is connected to the two-way adjustment tooth plate 2 and the base body 1 through the connection structure, the third adjustment region on the inner end face of the support 3 meshes with the long teeth in the first adjustment region on the outer end face of the two-way adjustment tooth plate 2, for adjusting the position of the support 3 in the first direction, and the fourth adjustment region on the inner end face of the support 3 meshes with the long teeth in the second adjustment region on the outer end face of the two-way adjustment tooth plate 2, for adjusting the position of the support 3 in the second direction.

In addition, in a set of opposite end faces of the matched bidirectional adjustment tooth plate 2 and the support 3, two tooth structures can be adopted. For example, triangular cross-section teeth are used in the first adjustment area and the third adjustment area, and trapezoidal cross-section teeth are used in the second adjustment area and the fourth adjustment area.
