Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a fixed base for a surveying and mapping instrument. Background Art

[0002] A surveying instrument is an instrument used for measuring and drawing, and is widely used in engineering construction, topographic surveying, construction layout and other fields. A surveying instrument is usually composed of a telescope, a horizontal plate, a base and other components. It can measure horizontal and vertical angles, as well as distance and elevation. It can input the measurement data into a computer for processing, and can directly take photos for archiving or do surface observation, measurement and drawing. There are many types of surveying instruments, including theodolites, levels, planar meters, etc. Surveying instruments often need to be used with a bracket. When in use, the surveying instrument needs to be fixed to the bracket through the base.

[0003] In the existing patent application with application number CN202222352739.1, a base quick-release structure for an engineering surveying instrument is proposed. Although the installation base and the support seat can be installed by rotating the driving rod to drive the driving wheel to rotate, so that the installing threaded column is threadedly installed inside the threaded groove, the steps of disassembling and assembling the surveying instrument by rotating the driving rod to drive the driving wheel and the installing threaded column to rotate are still relatively cumbersome, and need to be further simplified to further improve the efficiency of disassembling and assembling the surveying instrument, thereby further improving the efficiency of using the surveying instrument. Utility Model Content

[0004] The main purpose of the utility model is to provide a surveying instrument fixing base, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A surveying instrument fixed base includes a mounting base, on which two connecting and fixing structures are symmetrically mounted, and the mounting base is mounted on a supporting tripod via the two connecting and fixing structures, the connecting and fixing structure consists of a base plate, a limit block and a limit spring, the limit block is fixedly mounted on the lower end of the base plate, the limit spring is fixedly mounted on the inner end of the base plate, a limit plug is fixedly mounted on the lower end of the mounting base and between the two connecting and fixing structures, and the limit plug is simultaneously inserted into the supporting tripod.

[0007] Preferably, a surveying and mapping instrument is fixedly mounted on the mounting base.

[0008] Preferably, two mounting through slots are symmetrically provided on the mounting base, and mounting rods are fixedly installed in the mounting through slots.

[0009] Preferably, the supporting tripod is composed of a mounting plate and telescopic supporting legs, and there are three telescopic supporting legs which are all rotatably mounted on the mounting plate.

[0010] Preferably, a plurality of connecting through grooves are symmetrically provided on the mounting plate, and a limiting socket is provided on the mounting plate and on the inner sides of the plurality of connecting through grooves, and the connecting through grooves and the limiting socket both penetrate the mounting plate from top to bottom.

[0011] Preferably, the limit pin is inserted into the limit hole opened on the mounting plate, and a mounting hole is opened on the base plate on the connecting and fixing structure. The base plate is movably mounted on the mounting rod fixedly installed in the mounting groove through the mounting hole, and the limit spring is sleeved on the mounting rod. The base plate can pass downward through the mounting groove opened on the mounting plate, and the limit block can pass downward through the mounting groove opened on the mounting plate and move to the bottom of the mounting plate.

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

[0013] By arranging a connecting and fixing structure and a limit plug on the mounting base, the disassembly and assembly steps between the surveying and mapping instrument and the supporting tripod can be simplified, thereby further improving the disassembly and assembly efficiency of the surveying and mapping instrument and the supporting tripod, and further improving the use efficiency of the surveying and mapping instrument. When the surveying and mapping instrument is installed and fixed on the supporting tripod, it is only necessary to insert the limit plug into the limit plug hole, and at the same time, the limit block on the connecting and fixing structure is passed downward through the connecting groove. Finally, under the elastic force of the limit spring, the limit block is stuck at the lower end of the mounting plate. When the surveying and mapping instrument needs to be separated from the supporting tripod, it is only necessary to push the base plate inward. When the base plate contacts the inner wall of the connecting groove, the surveying and mapping instrument and the mounting base can be moved upward, so that the limit block can be passed upward through the connecting groove.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a surveying instrument fixed base comprises a mounting base 1, on which a surveying instrument 4 is fixedly mounted, two mounting through slots 9 are symmetrically provided on the mounting base 1, in which mounting rods 10 are fixedly mounted, a supporting tripod 3 is composed of a mounting plate 5 and telescopic supporting legs 6, and there are three telescopic supporting legs 6 which are all rotatably mounted on the mounting plate 5, a plurality of connecting through slots 7 are symmetrically provided on the mounting plate 5, a limiting plug hole 8 is provided on the mounting plate 5 and on the inner side of the plurality of connecting through slots 7, and both the connecting through slots 7 and the limiting plug hole 8 penetrate the mounting plate 5 from top to bottom.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, two connecting and fixing structures 2 are symmetrically installed on the mounting base 1, and the mounting base 1 is installed on the supporting tripod 3 through the two connecting and fixing structures 2. The connecting and fixing structure 2 is composed of a base plate 12, a limit block 13 and a limit spring 14. The limit block 13 is fixedly installed at the lower end of the base plate 12, and the limit spring 14 is fixedly installed at the inner end of the base plate 12. A limit plug 11 is fixedly installed at the lower end of the mounting base 1 and between the two connecting and fixing structures 2. The limit plug 11 is inserted into the supporting tripod 3 at the same time. The limit plug 11 is inserted into the limit plug hole 8 opened on the mounting plate 5. The base plate 12 on the connecting and fixing structure 2 is provided with a limit plug. The mounting hole 15 is used for movably mounting the base plate 12 on the mounting rod 10 fixedly mounted in the mounting groove 9 through the mounting hole 15. The limit spring 14 is sleeved on the mounting rod 10. The base plate 12 can pass downward through the mounting groove 9 provided on the mounting plate 5. The limit block 13 can pass downward through the mounting groove 9 provided on the mounting plate 5 and move to the bottom of the mounting plate 5. By arranging the connecting fixing structure 2 and the limit plug 11 on the mounting base 1, the disassembly and assembly steps between the surveying and mapping instrument 4 and the supporting tripod 3 can be simplified, thereby further improving the disassembly and assembly efficiency of the surveying and mapping instrument 4 and the supporting tripod 3, and further improving the use efficiency of the surveying and mapping instrument 4.

[0022] It should be noted that the utility model is a surveying instrument fixing base. When the surveying instrument 4 is installed and fixed on the supporting tripod 3, it is only necessary to insert the limit plug 11 downward into the limit plug hole 8 opened on the mounting plate 5, and at the same time, the limit block 13 on the connecting and fixing structure 2 is downwardly passed through the connecting through groove 7 opened on the mounting plate 5. When the limit block 13 enters the connecting through groove 7, the squeezed limit block 13 and the base plate 12 will slide inward on the mounting rod 10. At this time, the limit spring 14 will be compressed by the base plate 12. When the limit block 13 passes through the connecting through groove 7 downward, the limit spring 14 will be compressed by the base plate 12. Under the elastic force of the positioning spring 14, the base plate 12 and the limit block 13 will move outward, and finally the limit block 13 will be stuck at the lower end of the mounting plate 5. At this time, the surveying and mapping instrument 4 and the mounting base 1 are fixed on the supporting tripod 3; when it is necessary to separate the surveying and mapping instrument 4 from the supporting tripod 3, it is only necessary to push the base plate 12 inward. When the base plate 12 contacts the inner wall of the connecting groove 7, the surveying and mapping instrument 4 and the mounting base 1 can be moved upward, so that the limit block 13 on the connecting and fixing structure 2 passes upward through the connecting groove 7. At this time, the surveying and mapping instrument 4 and the supporting tripod 3 are separated.
