Description

Technical Field

[0001] The utility model belongs to the technical field of tripods, and more specifically, particularly relates to a tripod for a surveying and mapping instrument. Background Art

[0002] Surveying instruments are important construction tools in surveying work. Surveying instruments require auxiliary support from other equipment during use. These support devices usually use tripods. However, tripods are mostly designed with a bottom cone structure during application, mainly for use on soft soil and uneven ground. This structure results in poor mobility on flat ground. The frame needs to be moved as a whole during movement, which is not convenient for position adjustment within a small range.

[0003] Based on the above, the inventors have found the following problems: during the use of the existing surveying instrument tripod, the surveying instrument needs to be leveled by the tripod, but leveling the tripod on some irregular roads will bring inconvenience to the staff, and the tripod cannot be fine-tuned, which will reduce the use efficiency of the tripod.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a surveying instrument tripod is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0005] The purpose and effect of the tripod for surveying and mapping instrument of the utility model are achieved by the following specific technical means:

[0006] A surveying instrument tripod comprises a support platform, a plurality of fixing frames are installed at the bottom end of the support platform, a support rod is arranged inside the fixing frame, a support member is installed at the bottom end of the support rod, a chamber is arranged inside the support member, and an adjustment mechanism is installed inside the chamber.

[0007] Furthermore, the adjustment mechanism includes a bevel gear 1, a threaded rod is fixedly installed on the bottom end of the bevel gear 1, a slider is installed on the surface of the threaded rod through a thread, a movable block is fixedly installed on the bottom end of the slider through a connecting rod, and a supporting foot is fixedly installed on the bottom end of the movable block.

[0008] Furthermore, a handle is provided on one side surface of the support member, and an output end of the handle passes through the support member to the inside of which a second bevel gear is fixedly installed, and the second bevel gear is meshed with the first bevel gear.

[0009] Furthermore, a pedal is fixedly mounted on the surface of the support rod.

[0010] Furthermore, a fixing bolt is provided on one side of the fixing frame.

[0011] Furthermore, the support platform, support rod and fixing frame are all made of carbon fiber material.

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

[0013] Through the cooperation between bevel gear one and bevel gear two, first, when the staff uses the tripod, they can lower the support rod through the fixing bolts. After the staff adjusts to a suitable height according to their own height, they can install the surveying instrument on the support platform. Then, when the instrument needs to be leveled, the handle can be turned to drive bevel gear two and bevel gear one to rotate, and then the slider can be driven to move. The height of the movable block and the support foot can be fine-tuned, which is convenient for the staff to level the instrument. The operation steps are very simple, which indirectly brings convenience to the staff, and the design greatly increases the practicality.

[0014] The carbon fiber material design makes the tripod have the characteristics of high strength and light weight, which can provide stable support and reduce the overall weight. It is suitable for surveying and mapping instruments that require high stability and portability, which indirectly improves the use efficiency of the tripod. BRIEF DESCRIPTION OF THE DRAWINGS
