Technical Field

[0001] The utility model belongs to the technical field of measuring instrument brackets, in particular to a portable measuring instrument bracket. Background Art

[0002] Engineering surveying instruments are instruments for various types of orientation, distance, angle, height, mapping and photogrammetry required for surveying work during the planning, design, construction and management stages of engineering construction. When using a surveying instrument, it is also necessary to use a bracket.

[0003] In the Chinese utility model patent with publication number CN218348324U, a portable measuring instrument bracket is provided. When the bracket needs to be carried out for measurement, multiple supporting parts are folded inward so that the cross bar passes through the through slot on the slider. Under the action of the limit block, the cross bar can be restricted on the slider, and the multiple supporting parts can be restricted on the cross bar at the same time, so that the multiple supporting parts can be fixed, avoiding the bracket from being loose when carried. The design uses the limit block and the cross bar to effectively fix the multiple supporting parts, thereby improving the portability of the bracket.

[0004] After searching and combining with actual measurement work experience, it is found that the measuring instrument bracket proposed in the above-mentioned comparative documents still has some defects and shortcomings in the process of implementation: it is not convenient to control the synchronous operation of multiple support parts, and it is not convenient to limit its maximum expansion range, and the bracket is prone to tipping over. When storing the bracket, it is necessary to push multiple sliders to move in sequence, and then use the snap-fit ​​method to achieve the positioning of the support part. The operation is complicated, and the height of the bracket is not adjustable. The volume is large, and it is difficult to meet the needs of outdoor measurement work for higher flexibility. Therefore, it is urgent to improve the existing portable bracket of the measuring instrument and provide a portable bracket of the measuring instrument. Utility Model Content
