[0002] Surveying and mapping instruments are instruments and devices designed and manufactured for surveying and mapping operations, such as data collection, processing, and output. They are various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction.

[0003] Application No. CN202222952681.4 The utility model belongs to the field of surveying and mapping instruments, specifically a leveling structure of a measuring and mapping instrument with a fixing function, including a fixed plate, a lifting mechanism fixedly connected to the bottom of the fixed plate, the lifting mechanism including a bearing plate, a threaded column, a rotating block and a top column, and a threaded column fixedly connected to the top of the bearing plate; the fixed plate is operated and connected for fixed use, and the internal lifting mechanism can be adjusted when in use, and the internal rotating block is directly held and rotated to adjust the height of the internal threaded column, and the internal multiple rotating blocks are rotated at the same time to adjust the height, so as to solve the problem that due to the use restrictions of some surveying and mapping instruments, it is not convenient to adjust, resulting in the need to adjust the support frame of the bottom plate during operation, which is not convenient to use and increases the use of adjustment steps, thereby achieving the effect of facilitating adjustment.

[0004] Based on the search of the above patents and the application of the leveling structure of existing surveying and mapping instruments, it is understood that: currently, when the surveying and mapping instrument is in use, if it is tilted, it will affect the surveying and mapping results, and most leveling methods require manual adjustment and cannot be adjusted adaptively. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a leveling structure for a surveying and mapping instrument to solve the problem that if the existing surveying and mapping instrument is tilted during use, it will affect the surveying and mapping results, and most leveling means require manual adjustment and cannot be adjusted adaptively.

[0006] The purpose and effect of the leveling structure of a surveying and mapping instrument of the utility model are achieved by the following specific technical means:

[0007] A leveling structure for a surveying and mapping instrument comprises a base; the rear end position of the base is fixedly connected to the lower position of the front end of a lifting frame, a sliding rod is arranged on both sides of the front end of the lifting frame, the two sliding rods are symmetrically distributed on both sides of a threaded rod, the threaded rod is rotatably connected to the middle position of the lifting frame, the sliding rod is slidably connected to both sides of the rear end of a lifting plate, the lifting plate is located at the front end position of the lifting frame, an adjustment seat is fixedly installed at the middle position of the front end of the lifting plate, slots are arranged on both sides of the adjustment seat, and sockets are arranged on both sides of the front end of the lifting plate, the sockets of the lifting plate are flush with the slots of the adjustment seat, and the sockets of the lifting plate and the slots of the adjustment seat are plugged in through the plug rods.

[0008] According to an embodiment of the utility model, a threaded hole is opened in the middle position of the top rear end of the lifting plate, and the threaded rod is located inside the threaded hole of the lifting plate.

[0009] According to an embodiment of the utility model, a semicircular groove is provided at a middle position of the top of the adjustment seat, and a through groove is provided at a bottom position of the semicircular groove of the adjustment seat.

[0010] According to one embodiment of the utility model, a leveling ball is placed in the semicircular groove of the adjustment seat, and the bottom position of the leveling ball is fixedly connected to a counterweight block through an extension rod. The counterweight block is located below the adjustment seat and has a cylindrical structure design. The counterweight block is located above the base.

[0011] According to an embodiment of the utility model, a clamp is fixedly connected to the upper position of the leveling ball, the clamp is located directly above the counterweight block, and the surveying instrument body is clamped on the upper inner side of the clamp.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When the surveying instrument body needs to be adjusted horizontally, the surveying instrument body is placed in the internal position of the fixture for fixed installation, and then the base is placed in the detection position. With the cooperation of the counterweight block and the leveling ball, the leveling ball will adaptively rotate in the semicircular groove of the adjustment seat to ensure that the fixture above the leveling ball is in a horizontal state. Then the surveying instrument body can achieve adaptive adjustment effect, avoiding manual intervention adjustment, which is troublesome and will also cause adjustment errors.

[0014] When the threaded rod is rotated, the threaded rod cooperates with the threaded hole of the lifting plate to drive the lifting plate to slide downward until the bottom position of the counterweight block contacts the top position of the base. When the lifting plate continues to move downward, the bottom position of the adjustment seat fits with the top position of the counterweight block, thereby limiting the counterweight block. At this time, the surveying instrument body fixed by the clamp will not shake, so there is no need to remove the surveying instrument body when the device is moved. BRIEF DESCRIPTION OF THE DRAWINGS
