Description

Technical Field

[0001] The present application relates to the technical field of surveying and mapping equipment, and in particular to an adjustable surveying and mapping instrument mounting bracket. Background Art

[0002] A surveying instrument is a professional measuring device. In order to ensure the stability of the surveying instrument when using it, it is generally installed on a professional surveying instrument mounting bracket. By adjusting the position and height of the mounting bracket, the laser point of the surveying instrument is aligned with the control point to ensure the accuracy of the measurement.

[0003] For example, a surveying instrument support device for surveying and mapping engineering with patent number (CN202121913140.X) includes a mounting plate and a surveying instrument body, and is characterized in that: an inner bracket is equidistantly installed at the bottom end of the mounting plate, the inner bracket is inserted into the inside of the outer bracket, a connecting rod is installed on the top of the outer bracket, the connecting rod is equidistantly installed on the positioning plate, the positioning plate and the mounting plate bracket are connected through an adjustment assembly, and a stabilizing member is installed at the bottom end of the outer bracket.

[0004] In the above structure, when in use, the support device is placed above the control point to align the laser point of the surveying instrument with the control point; after the surveying instrument is installed on the bracket, it needs to be leveled, and after leveling, there will be a slight deviation between the laser point of the surveying instrument and the control point; when using this device, since the installation position of the surveying instrument relative to the support device is fixed, secondary alignment can only be achieved by moving the support device again, which is prone to large deviations and inconvenient to operate.

[0005] Therefore, it is necessary to design an adjustable surveying instrument mounting bracket which is convenient for adjusting the mounting position of the surveying instrument, so as to facilitate secondary alignment of the laser point and the control point. Utility Model Content

[0019] Further, the driving member is a driving screw, and the driving screw is threadedly connected to the slider;

[0020] The driving screw is rotatably arranged on the base.

[0021] Furthermore, the top surface of the base is partially concave to form a moving groove, and the connecting plate is arranged in the moving groove;

[0022] The bottom surface of the moving groove is partially concave to form a driving groove, and the extending direction of the driving groove is perpendicular to the extending direction of the connecting plate;

[0023] The driving screw is rotatably arranged in the driving groove.

[0024] Furthermore, one end of the driving screw is inserted through the side wall of the base to form a knob portion.

[0025] Furthermore, the support assembly comprises:

[0026] Three outer support rods, distributed in a circular array below the base, and hinged to the base at their ends;

[0029] Furthermore, the outer support rod is partially concave near the bottom to form a telescopic groove;

[0030] A limiting groove corresponding to the telescopic groove is formed on the inner support rod, and a plurality of the limiting grooves are arranged in a linear array along the extending direction of the inner support rod;

[0031] A limiting shell corresponding to the position of the telescopic slot is fixedly arranged on the outer supporting rod, and the limiting member is movably arranged in the limiting shell.

[0032] Furthermore, one end of the limiting member away from the limiting groove is fixedly connected to the limiting shell through an elastic member;

[0034] Furthermore, one end of the inner support rod away from the base forms a tapered portion.

[0035] The beneficial effect of the present application is that an adjustable surveying instrument mounting bracket is provided, which is convenient for adjusting the mounting position of the surveying instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The outer support rod 201 is partially concave near the bottom to form a telescopic slot 204 that penetrates the side wall of the outer support rod 201, and a limiting slot 205 corresponding to the telescopic slot 204 is formed on the inner support rod 202. The inner support rod 202 is provided with a plurality of limiting slots 205 in a linear array along the extension direction; a limiting shell 206 corresponding to the telescopic slot 204 is provided on the outer support rod 201, and a limiting member 203 is movably arranged in the limiting shell 206; one end of the limiting member 203 away from the limiting slot 205 is fixedly connected to the limiting shell 206 by a spring 207; the side wall of the limiting shell 206 is partially concave to form an unlocking slot 208, and an unlocking block 209 is inserted through the unlocking slot 208 and fixedly connected to the limiting member 203;

[0056] When the spring 207 is in a relaxed state, the limit piece 203 passes through the telescopic slot 204 and engages with the limit slot 205; when unlocking, the unlocking block 209 is pushed, and the unlocking block 209 drives the limit piece 203 to squeeze the spring 207, and the limit piece 203 is disengaged from the limit slot 205. At this time, the inner support rod 202 can be retracted, and the unlocking block 209 is released.
