Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a highly controllable surveying and mapping instrument. Background Art

[0002] Surveying and mapping instruments refer to instruments and devices designed and manufactured for surveying and mapping operations, such as data collection, processing, and output. They are used during the planning, design, construction, and management phases of engineering projects, and involve tasks such as orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry.

[0003] Among existing Chinese utility models, the publication number CN220205308U discloses a surveying instrument that is easy to adjust the surveying height, including a surveying instrument body, a bracket installed at the bottom end of the surveying instrument body, buttons evenly distributed on the front of the lower side of the surveying instrument body, and a transparent plate covering the lower side of the surveying instrument body. The transparent plate has insertion slots at positions corresponding to the buttons, and a protective cover is provided on the front of the insertion slot. The utility model is provided with a protective cover and a transparent plate. In actual use, the transparent plate and the protective cover cooperate with each other to protect the graphics on the buttons to prevent them from being worn off during use, which is convenient for staff to use normally. A support plate and a rotating plate are provided. When in use, the rotating plate can block sunlight, thereby facilitating staff to normally view the content displayed on the display screen and facilitating staff to operate the surveying instrument body.

[0004] Referring to the aforementioned surveying instrument with adjustable height, the height of the surveying instrument is adjusted by adjusting the length of the tripod. However, during the height adjustment process, the opening and closing angles of the tripod are inevitably affected, causing the level of the entire surveying instrument to change. This requires the instrument to be re-leveled after each adjustment of the tripod height, making the height adjustment operation relatively inconvenient. Therefore, how to effectively adjust the height of the surveying instrument without affecting the horizontal placement of the surveying instrument is an important issue that needs to be addressed in the design of a height-controllable surveying instrument.

[0055] The positions of the pressing block 1005 and the pressing tip block 1006 correspond to the position of the rotating block 1 605 .

[0056] A fixing ring 11 is fixedly connected to the inner side walls of the top and bottom of the placement cavity 9, and six limiting rods 2 12 are fixedly connected to the side walls of the fixing ring 11 at equal distances. The other ends of the six limiting rods 2 12 are fixedly connected to the inner side walls of the placement cavity 9, and the six limiting rods 2 12 are slidably connected to the push block 1004.

[0058] When the present invention is in use, the electrical components appearing in the present application are all externally connected to a power supply and a control switch. When placing the surveying and mapping instrument, the three bracket rods 3 are pulled apart, and the angles of the three bracket rods 3 are adjusted respectively so that the entire surveying and mapping instrument is placed horizontally. The three supporting structures 6 corresponding to the three bracket rods 3 are independent of each other. Therefore, when adjusting the opening angle of the bracket rod 3, it will not be affected by the other two bracket rods 3. When pulling the bracket rod 3, the bracket rod 3 drives the fixed block 601 to move, the fixed block 601 pulls the connecting rod 602 to move, the connecting rod 602 pulls the fixed frame 603 to move, the fixed frame 603 moves on the threaded rod 604 and synchronously drives the threaded rod 604 to rotate, the rotation of the threaded rod 604 drives the rotating block 605 to rotate, and the rubber pad 606 rotates with the rotation of the rotating block 605.

[0059] After adjustment, turn the handle block 1014 again, the handle block 1014 drives the rotating block 2 1013 to rotate, the rotating block 2 1013 drives the threaded rod 2 1011 to rotate, the threaded rod 2 1011 rotates and drives the moving ring 1012 to move, the moving ring 1012 drives the fixed block 2 1001 to move, the fixed block 2 1001 moves and drives the connecting rod 2 1002 to move, the connecting rod 2 1002 drives the fixed block 3 1003 to move, the fixed block 3 1003 drives the pushing block 1004 to move, the pushing block 1004 drives the pressing block 1005 to move, so that the pressing block 1005 is tightly pressed against the rubber pads 606 on the three rotating blocks 1 605, and the pressing tip 1006 on the pressing block 1005 is tightly pressed into the rubber pad 606, thereby better fixing the three rotating blocks 1 605 synchronously;

[0060] The fixed rotating block 605 restricts the rotation of the threaded rod 604. If the threaded rod 604 cannot rotate, the fixing frame 603 cannot move, thereby forming a stable triangle between the support rod 3, the connecting rod 602 and the threaded rod 604. The angle of the support rod 3 is well fixed, so that the entire surveying and mapping instrument can be stably placed on the ground.

[0061] When adjusting the height, the rotating threaded sleeve 201 is rotated, and the limit rod 204 can limit the rotation of the lifting threaded cylinder 202, so that the rotation of the rotating threaded sleeve 201 can drive the lifting threaded cylinder 202 to rise, and the lifting threaded cylinder 202 drives the surveying and mapping instrument body 4 to rise. Since the bracket rod 3 is fixed and cannot be rotated, it is convenient to adjust the height of the surveying and mapping instrument better without affecting the horizontal placement of the surveying and mapping instrument during operation.

[0062] The present invention is not limited to the above-described embodiments. Any changes in shape or structure fall within the scope of protection of the present invention.
