Technical Field

[0001] The present invention relates to the technical field related to engineering surveying and mapping brackets, and in particular to a windproof engineering surveying and mapping bracket. Background Art

[0002] In construction projects, in order to make each module meet the requirements, it is necessary to use surveying tools for measurement to ensure that there will be no deviation during construction. Then, in order to improve the stability of the surveying equipment during use, it is necessary to use brackets to improve its stability. Reference publication number CN210661961U is a surveying instrument bracket for surveying and mapping engineering. The bracket cooperates with a cam and a movable sleeve plate, and when the cam rotates, the movable sleeve plate is driven to move upward or downward. When the movable sleeve plate moves upward, it will drive the support plate to move upward. When both sets of support plates move upward, the lifting platform will drive the surveying instrument to move upward, thereby conveniently adjusting the height of the bracket. However, there are still the following problems: In the actual use of the above device, although the purpose of adjusting the height is achieved by moving the support plate, the stability of the bracket will decrease as the height changes, and when the height increases, the windward area will also increase, so that the bracket may move in the wind, thereby reducing the accuracy of surveying and mapping.

[0003] Therefore, we proposed a windproof engineering surveying and mapping bracket that can solve the above problems well. Summary of the invention

[0010] Preferably, fixing rods are fixed to both sides of the bottom of the bracket body by screws, and the bottoms of the fixing rods are slidably engaged in the interior of the accommodating frame.

[0011] Through the above structural arrangement, the accommodating rack can be raised and lowered.

[0012] Preferably, the inner end of the fixing rod is threadedly connected to a rotating rod, and the top of the rotating rod is rotatably connected to the top end of the interior of the accommodating frame via a bearing.

[0013] Through the above structural arrangement, the rotating rod can be rotated.

[0014] Preferably, a stabilizing rod is fixed to the bottom of the rotating rod, and the stabilizing rod is arranged in a spiral shape, and the bottom of the rotating rod passes through the bottom of the accommodating frame.
