Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping instruments, in particular to a folding bracket of a surveying and mapping instrument and a surveying and mapping device. 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 installed and fixed on a tripod. In order to facilitate the carrying of the tripod, traditional tripods all have the function of folding and retracting. In the existing patent application with application number CN201620517675.8, a surveying instrument bracket is proposed. However, the inner rod and the sleeve rod of the bracket are fixed by bolts installed on the sleeve rod. Therefore, when adjusting and moving the inner rod, it is necessary to rotate the bolt first so that the bolt and the inner rod are out of contact, thereby releasing the fixation of the inner rod and the sleeve rod. When the movement and adjustment of the inner rod is completed, it is necessary to rotate the bolt in the opposite direction again to press the bolt against the inner rod, thereby fixing the inner rod and the sleeve rod by utilizing the friction between the bolt and the inner rod. This process is relatively cumbersome, which will result in low efficiency in the movement and adjustment of the inner rod, thereby reducing the adjustment efficiency of the instrument installed on the bracket. At the same time, the inner rod and the sleeve rod are fixed only by the friction between the bolt and the inner rod, and the fixing effect is poor. When the instrument installed on the bracket is heavy, the inner rod and the sleeve rod are prone to relative displacement under the action of the weight of the instrument, so it needs to be improved. Utility Model Content

[0003] The main purpose of the utility model is to provide a folding bracket for a surveying and mapping instrument and a surveying and mapping device, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A folding bracket for a surveying and mapping instrument comprises a mounting connecting plate, three rotating support legs are rotatably mounted on the mounting connecting plate, telescopic support legs are slidably mounted on the rotating support legs, a fixed structure is movably mounted on the telescopic support legs, the fixed structure consists of a base plate, a rack, a connecting rod, a fixed spring and an anti-slip baffle, there are two racks and they are symmetrically fixedly mounted on the left and right ends of the base plate, there are three connecting rods and they are evenly fixedly mounted on the inner end of the base plate, there are three fixing springs and they are respectively sleeved on the three connecting rods, and there are three anti-slip baffles and they are respectively fixedly mounted on the inner ends of the three connecting rods.

[0006] Preferably, the rotating support leg is composed of a connecting member and a connecting arm, the connecting member is rotatably mounted on the mounting connecting plate, the connecting arm has two connecting arms which are symmetrically fixedly mounted on the lower end of the connecting member, a U-shaped mounting groove is provided at the inner end of the connecting arm, and a tooth groove is provided at the inner end of the connecting arm and on the outer side of the U-shaped mounting groove.

[0007] Preferably, the telescopic support leg is slidably installed in two U-shaped installation grooves opened at the inner ends of the two connecting arms, three spring receiving grooves are evenly opened at the outer end of the telescopic support leg, and three through holes are evenly opened at the inner end of the telescopic support leg, and the spring receiving grooves and the through holes are connected to each other.

[0008] Preferably, the base plate on the fixed structure is located outside the telescopic supporting leg, and the base plate is also located between the two connecting arms, and the rack can be engaged with the tooth groove provided at the inner end of the connecting arm.

[0009] Preferably, the connecting rod on the fixed structure is inserted into a spring receiving groove and a through hole provided on the telescopic supporting leg, the fixed spring is located in the spring receiving groove, and the anti-slip baffle is located on the inner side of the telescopic supporting leg.

[0010] A surveying and mapping device comprises a surveying and mapping device and the above-mentioned surveying and mapping instrument folding bracket, wherein the surveying and mapping device is fixedly mounted on the upper end of a mounting connecting plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By arranging a fixing structure on the telescopic support leg, the fixing and releasing of the telescopic support leg and the rotating support leg can be made simpler and more convenient, thereby making the adjustment efficiency of the telescopic support leg higher, and further making the adjustment efficiency of the surveying and mapping equipment higher. When it is necessary to release the fixing between the telescopic support leg and the rotating support leg, it is only necessary to push the base plate and the rack on the fixing structure toward the telescopic support leg, so that the rack and the tooth groove on the rotating support leg are disengaged. When it is necessary to fix the telescopic support leg and the rotating support leg, the base plate and the rack can be loosened. At this time, under the elastic force of the fixing spring, the rack will move away from the telescopic support leg, so that the rack and the tooth groove can be engaged. At the same time, the existence of the fixing structure can make the fixing effect between the telescopic support leg and the rotating support leg better. Under the heavy pressure of the surveying and mapping equipment, the telescopic support leg and the rotating support leg are not easy to produce relative displacement.
