Description

Technical Field

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

[0002] Surveying and mapping is the process of measuring and drawing. Based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with the global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS) as the core technology, the existing characteristic points and boundaries on the ground are measured to obtain graphics and location information reflecting the current situation of the ground for the planning, design, and administrative management of engineering construction. A surveying instrument is generally composed of a surveying instrument and a surveying bracket;

[0003] Most of the existing surveying instruments and surveying brackets adopt an integrated design, and the surveying bracket generally adopts a double-section structure. The double-section structure can be suitable for users of different heights to a certain extent. However, the integrated design of the surveying instrument and the bracket causes the surveying instrument and the bracket to be stored together in a storage box during transportation and carrying of the surveying instrument. This method makes the storage box relatively large, which is not conducive to transportation. At the same time, its large size makes it difficult for operators to carry it alone. Therefore, a portable geographic information surveying instrument is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a portable geographic information surveying and mapping instrument that can solve the problems of the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable geographic information surveying and mapping instrument, comprising a mounting plate, three supporting legs are rotatably connected to the mounting plate, telescopic legs are slidably connected inside the supporting legs, one end of the telescopic legs away from the supporting legs is fixedly connected to a fixing nail, a surveying and mapping instrument body is arranged on the mounting plate, an adjusting knob is rotatably connected to the side of the mounting plate away from the surveying and mapping instrument body, a fixed threaded rod is threadedly connected to the supporting legs, a mounting groove is opened on the mounting plate, and a disassembly and assembly component is arranged inside the mounting groove.

[0006] Preferably, the disassembly and assembly assembly includes a fixing rod, which is rotatably connected to the inside of the mounting groove, the fixing rod is fixedly connected to the adjusting knob, a connecting sleeve is fixedly connected to the bottom of the surveying instrument body, a slot is provided on the inner wall of the connecting sleeve, a through hole is provided on the fixing rod, a fixing rod is slidably connected to the inside of the through hole, a limiting rod is slidably connected to the inside of the fixing rod, the limiting rod passes through the fixing rod and the adjusting knob and extends to the outside of the adjusting knob, a limiting slot is provided on the limiting rod, the upper end of the limiting rod is fixedly connected to a second elastic component, the other end of the second elastic component is fixedly connected to the inner wall of the fixing rod, one end of the fixing rod close to the limiting rod is fixedly connected to a limiting ball, a first elastic component is movably sleeved on the fixing rod, and two ends of the first elastic component are respectively fixedly connected to the surface of the limiting ball and the inner wall of the fixing rod.

[0007] Preferably, the end of the clamping rod away from the limiting ball is arc-shaped.

[0008] Preferably, a docking groove is provided on the connecting sleeve, a docking block is fixedly connected to the fixing rod, and soft magnets are fixedly connected to the inner wall of the mounting groove and the surface of the connecting sleeve.

[0009] Preferably, the limiting groove is arc-shaped, and the limiting ball is half spherical.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) When the portable geographic information surveying and mapping instrument needs to be installed between the surveying and mapping instrument body and the mounting plate, it is only necessary to insert the connecting sleeve into the interior of the mounting groove and push the limiting rod upward, so that the limiting ball is located at the position of the limiting groove. At this time, the second elastic component is in a compressed state and the first elastic component is in a normal state. When the slot on the connecting sleeve moves to the position of the limiting rod, the limiting rod is no longer exerted with force. At this time, the second elastic component releases the thrust to reset the limiting rod, so that the limiting ball is separated from the interior of the limiting groove. At this time, the limiting ball contacts the surface of the limiting rod and is limited. The change in the surface diameter of the limit rod causes the clamping rod to move outward and be inserted into the inside of the clamping slot, thereby completing the fixation between the surveying instrument body and the mounting plate. When disassembly is required, it is only necessary to push the limit rod again. Therefore, the disassembly and installation between the surveying instrument body and the mounting plate are more convenient and quick, thereby facilitating the carrying of the surveying instrument body and avoiding the phenomenon that the surveying instrument body cannot be stored due to the integral structure of the surveying instrument and the supporting legs. The surveying instrument body can be stored separately in the storage box, thereby reducing the bumps caused during carrying and avoiding damage.

[0012] (2) The portable geographic information surveying and mapping instrument, by providing a docking groove and a docking block, can limit the position of the connecting sleeve, and can then preliminarily calibrate the position of the slot and the position of the clamping rod, thereby ensuring normal installation between the surveying and mapping instrument body and the mounting plate.

DETAILED DESCRIPTION

[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a portable geographic information surveying and mapping instrument, including a mounting plate 1, three supporting legs 5 are rotatably connected to the mounting plate 1, telescopic legs 6 are slidably connected inside the supporting legs 5, and one end of the telescopic legs 6 away from the supporting legs 5 is fixedly connected with a fixing nail 7, a surveying and mapping instrument body 2 is arranged on the mounting plate 1, an adjusting knob 3 is rotatably connected to the side of the mounting plate 1 away from the surveying and mapping instrument body 2, a fixed threaded rod 8 is threadedly connected to the supporting legs 5, a mounting groove 11 is opened on the mounting plate 1, and a disassembly assembly is arranged inside the mounting groove 11;

[0021] By setting the fixed threaded rod 8, when the length of the telescopic leg 6 needs to be adjusted, it is only necessary to pull the telescopic leg 6. At this time, when the telescopic leg 6 reaches the specified length, the fixed threaded rod 8 is rotated so that the fixed threaded rod 8 and the surface of the telescopic leg 6 are in conflict with each other, thereby achieving the effect of fixing the telescopic leg 6;

[0022] The provision of the fixing nail 7 enables the device to be inserted into the ground, thereby improving its stability during use and preventing it from tilting or falling due to external forces, thereby ensuring the safety of the surveying instrument body 2 and preventing it from being damaged.

[0023] Further, the disassembly assembly includes a fixing rod 12, the fixing rod 12 is rotatably connected to the inside of the mounting groove 11, the fixing rod 12 is fixedly connected to the adjusting knob 3, the bottom of the surveying instrument body 2 is fixedly connected to a connecting sleeve 10, the inner wall of the connecting sleeve 10 is provided with a card slot 14, the fixing rod 12 is provided with a through hole 15, the inside of the through hole 15 is slidably connected to a card rod 16, the inside of the fixing rod 12 is slidably connected to a limit rod 4, the limit rod 4 passes through the fixing rod 12 and the adjusting knob 3 and extends To the outside of the adjustment knob 3, a limiting groove 9 is provided on the limiting rod 4, the upper end of the limiting rod 4 is fixedly connected with a second elastic component 19, the other end of the second elastic component 19 is fixedly connected to the inner wall of the fixing rod 12, and the end of the clamping rod 16 close to the limiting rod 4 is fixedly connected with a limiting ball 17 in the shape of a half sphere, and the clamping rod 16 is movably sleeved with a first elastic component 18, and the two ends of the first elastic component 18 are respectively fixedly connected to the surface of the limiting ball 17 and the inner wall of the fixing rod 12;

[0024] The end of the clamping rod 16 away from the limiting ball 17 is arc-shaped;

[0025] When it is necessary to install the surveying instrument body 2 and the mounting plate 1, it is only necessary to insert the connecting sleeve 10 into the inside of the mounting groove 11 and push the limiting rod 4 upward, so that the limiting ball 17 is located at the position of the limiting groove 9. At this time, the second elastic component 19 is in a compressed state, and the first elastic component 18 is in a normal state. When the card slot 14 on the connecting sleeve 10 moves to the position of the card rod 16, the limiting rod 4 is no longer exerted. At this time, the second elastic component 19 releases the thrust to reset the limiting rod 4, so the limiting ball 17 is disengaged from the inside of the limiting groove 9. At this time, the limiting ball 17 is in contact with the surface of the limiting rod 4 and is therefore limited. The change in the surface diameter of the limit rod 4 causes the clamping rod 16 to move outward and be clamped into the inside of the clamping slot 14, thus completing the fixation between the surveying instrument body 2 and the mounting plate 1. When disassembly is required, it is only necessary to push the limit rod 4 again. Therefore, the disassembly and installation between the surveying instrument body 2 and the mounting plate 1 are more convenient and quick, thereby facilitating the carrying of the surveying instrument body 2, avoiding the phenomenon that the surveying instrument body 2 cannot be stored due to the integral structure of the surveying instrument body 2 and the supporting legs 5, and thus the surveying instrument body 2 can be stored separately in the storage box, thereby reducing the bumping phenomenon caused during carrying, thereby avoiding damage.

[0026] Furthermore, a docking groove 21 is provided on the connecting sleeve 10, and a docking block 20 is fixedly connected to the fixing rod 12;

[0027] By providing the docking groove 21 and the docking block 20 , the connecting sleeve 10 can be limited, and the position of the slot 14 and the position of the clamping rod 16 can be preliminarily calibrated, thereby ensuring the normal installation between the surveying instrument body 2 and the mounting plate 1 .

[0028] Furthermore, a soft magnet 13 is fixedly connected to the inner wall of the mounting groove 11 and the surface of the connecting sleeve 10;

[0029] By setting the soft magnet 13, when the surveying instrument body 2 needs to be adjusted in the reverse direction during use, the operator only needs to turn the adjusting knob 3. At this time, the adjusting knob 3 is subjected to force to drive the fixing rod 12 to be subjected to force together. Under the restriction of the docking block 20 and the docking groove 21, the connecting sleeve 10 drives the surveying instrument body 2 to rotate, so the observation direction of the surveying instrument body 2 can be conveniently adjusted. At this time, under the mutual adsorption of the soft magnets 13, the stability of the surveying instrument body 2 can be improved, so that it will not rotate arbitrarily, thereby ensuring the accuracy of the detection data.

[0030] Working principle: when it is necessary to install the surveying instrument body 2 and the mounting plate 1, it is only necessary to insert the connecting sleeve 10 into the inside of the mounting groove 11 and push the limiting rod 4 upward, so that the limiting ball 17 is located at the position of the limiting groove 9. At this time, the second elastic component 19 is in a compressed state and the first elastic component 18 is in a normal state. When the slot 14 on the connecting sleeve 10 moves to the position of the clamping rod 16, it no longer exerts force on the limiting rod 4. At this time, the second elastic component 19 releases the thrust to reset the limiting rod 4, so that the limiting ball 17 is separated from the inside of the limiting groove 9. At this time, the limiting ball 17 contacts the surface of the limiting rod 4, so it is affected by the change in the surface diameter of the limiting rod 4, and the clamping rod 16 moves outward and is clamped into the inside of the slot 14, so that the fixing between the surveying instrument body 2 and the mounting plate 1 is completed. When disassembly is required, it is only necessary to push the limiting rod 4 again, so that the surveying instrument body 2 and the mounting plate 1 are more convenient and quick to disassemble and install, thereby facilitating the carrying of the surveying instrument body 2.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
