Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping devices, and particularly relates to a portable surveying and mapping device. Background Technique

[0002] A surveying and mapping device is a device used to measure and map the shape, size, position, and other features of the Earth's surface or other objects. Surveying and mapping devices usually include surveying instruments, data acquisition devices, computer software, and drawing devices, etc. Common surveying and mapping devices include total stations, levels, GPS receivers, laser rangefinders, photogrammetry instruments, etc. These devices can be used to measure information such as the coordinates, elevations, distances, and angles of ground points, and convert this information into digital data for subsequent processing and analysis. Surveying and mapping devices are widely used in fields such as land surveying, urban planning, engineering construction, geological exploration, and map drawing. With the continuous development of technology, the accuracy and efficiency of surveying and mapping devices have been continuously improved, providing more reliable and efficient support for various surveying and mapping work.

[0003] According to a disclosed shock-absorbing bracket for a surveying and mapping device (publication number: CN220488688U), the three support legs of the tripod in the above application are hinged to the outermost extension of the top of the tripod, which results in a large gap between the three support legs of the tripod when they are retracted. The staff cannot grasp them with one hand, and the large gap causes the overall occupied space volume of the three support legs to be larger, which is not convenient for carrying and storing. Moreover, the angle adjustment of the support legs is limited. Content of the Utility Model

[0004] The purpose of the utility model is to provide a portable surveying and mapping device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A portable surveying and mapping device, including a mounting base, the top surface of the mounting base is fixedly connected with a surveying instrument, and a control part convenient for storage is arranged at the bottom of the mounting base. The control part includes:

[0006] A fixed rail, the top surface of the fixed rail is fixedly connected with the bottom surface of the mounting base. A cross-shaped slider is penetrated and slidably connected inside the fixed rail. The bottom surface of the cross-shaped slider is fixedly connected with a hinge block. A support leg is penetrated and hinged inside the hinge block. By pulling the support leg, the support leg drives the cross-shaped slider to slide inside the fixed rail and the folding rail through the hinge block. A cross-shaped limiting groove is opened inside the fixed rail. A connecting rod is penetrated and slidably connected inside the cross-shaped limiting groove. A rotating rod is penetrated and rotatably connected to the surface of the connecting rod;

[0007] A folding rail, wherein one side of the folding rail close to the connecting rod is fixedly connected to the surface of the connecting rod, and the surface of the folding rail close to the fixed rail is fixedly connected to an insertion rod, and a limiting hole is provided on the surface of the insertion rod. When the limiting hole provided on the surface of the insertion rod is aligned with the position of the limiting rod, the compressed spring will drive the cross rod by pushing the linkage rod to insert the limiting rod into the limiting hole.

[0008] Preferably, a slot is provided on the surface of one side of the fixed rail close to the folding rail. The folding rail is moved with the rotating rod as the axis so that the insertion rod fixedly connected to the surface of the folding rail is aligned with the slot and pushed into the slot. The surface of the fixed rail is penetrated and slidably connected with a limiting rod, and the limiting rod passes through the slot.

[0009] Preferably, a cross bar is fixedly connected to the surface of the limit rod, and the linkage rod will drive the limit rod through the cross bar so that it is no longer inserted into the limit hole, and the folding rail can be pulled out, so that the folding rail can pull the inserted rod out of the slot, and the end of the cross bar away from the limit rod is fixedly connected to the linkage rod.

[0010] Preferably, a shaft rod passes through and is rotatably connected to the inner side of the fixed rail, and the torsion rod is moved so that the torsion rod drives the cam to rotate around the shaft rod. When the cam rotates, it will contact the arc surface of the linkage rod, so that the linkage rod compresses the spring again.

[0011] Preferably, one end of the insertion rod close to the limiting rod is an inclined surface, and the bottom surface of the limiting rod is an arcuate surface. When the insertion rod is inserted into the slot, the inclined surface of the insertion rod gradually contacts the arcuate surface at the bottom end of the limiting rod.

[0012] Preferably, the shaft rod passes through and is fixedly connected to a cam, and a torsion rod is fixedly connected to the surface of the cam.

[0013] Preferably, the end of the linkage rod close to the cam is an arc-shaped surface, and the end of the linkage rod away from the cam is fixedly connected to a spring. The insertion rod is inserted into the slot, so that the limit rod is lifted up and the linkage rod is driven to rise together through the cross bar. The end of the spring away from the linkage rod is fixedly connected to the inner wall of the fixed rail.

[0014] Compared with the prior art, the utility model provides a portable surveying and mapping device with the following beneficial effects:

[0015] 1. After the portable surveying device is used, push the support legs and contract them to the central position of the mounting base. Then, turn the twisting rod, causing the cam to rotate around the shaft rod. When the cam rotates, it will contact the arc surface of the linkage rod, causing the linkage rod to compress the spring again. And the linkage rod will drive the limiting rod through the cross bar to no longer insert into the limiting hole, so that the folding rail can be pulled out. The folding rail can pull out the insertion rod from the slot. At the same time, the rotating rod is wider than the connecting rod, which can prevent the connecting rod from falling off and can also make the connecting rod rotate around the rotating rod, enabling the folding rail to fold down. The ability of the folding rail to fold can expand the support range of the support legs while making it more convenient for storage and carrying.

[0016] 2. For the portable surveying device, due to the foldable folding rail, the mounting base does not need to be of a large size, only needs to be able to fix the surveying instrument. The folding and extension of the matching fixed rail and folding rail can minimize the distance between the support legs, making it more convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1-6As shown in the figure, the utility model provides a technical solution: a portable surveying and mapping device, including a mounting base 1, on the top surface of the mounting base 1 is fixedly connected a surveying instrument 3, and at the bottom of the mounting base 1 is provided a control part 2 which is convenient for storage. The control part 2 includes: a fixed rail 21, a folding rail 22, a cross slider 23, a hinge block 24, a support leg 25, a cross limiting groove 26, a connecting rod 27, a rotating rod 28, a plug rod 29, a limiting hole 210, a slot 211, a limiting rod 212, a cross bar 213, a linkage rod 214, a spring 215, a shaft rod 216, a cam 217, and a twisting rod 218.

[0025] The top surface of the fixed rail 21 is fixedly connected to the bottom surface of the mounting base 1. The inner side of the fixed rail 21 penetrates and is slidably connected with the cross slider 23. The bottom surface of the cross slider 23 is fixedly connected with the hinge block 24. The inner side of the hinge block 24 penetrates and is hinged with the support leg 25. By pulling the support leg 25, the support leg 25 drives the cross slider 23 to slide within the fixed rail 21 and the folding rail 22 through the hinge block 24, which is more convenient for adjusting the distance and angle between the support legs 25. A cross limiting groove 26 is opened on the inner side of the fixed rail 21. The inner side of the cross limiting groove 26 penetrates and is slidably connected with the connecting rod 27. The surface of the connecting rod 27 penetrates and is rotatably connected with the rotating rod 28. The side of the folding rail 22 close to the connecting rod 27 is fixedly connected to the surface of the connecting rod 27. A plug rod 29 is fixedly connected to the surface of the folding rail 22 close to the fixed rail 21. A limiting hole 210 is opened on the surface of the plug rod 29. When the limiting hole 210 opened on the surface of the plug rod 29 is aligned with the position of the limiting rod 212, the compressed spring 215 drives the cross bar 213 through the linkage rod 214 to insert the limiting rod 212 into the limiting hole 210, so that the folding rail 22 is limited and cannot be pulled out.

[0026] On one side surface of the fixed rail 21 close to the folding rail 22, a slot 211 is provided. The folding rail 22 is toggled with the rotating rod 28 as the axis, so that the insertion rod 29 fixedly connected to the surface of the folding rail 22 is aligned with the slot 211 and pushed in, so that the insertion rod 29 is inserted into the slot 211. A limiting rod 212 penetrates and is slidably connected to the surface of the fixed rail 21, and the limiting rod 212 penetrates the slot 211. A cross bar 213 is fixedly connected to the surface of the limiting rod 212. The linkage rod 214 will drive the limiting rod 212 through the cross bar 213 to no longer insert into the limiting hole 210, and then the folding rail 22 can be pulled out, so that the folding rail 22 can pull the insertion rod 29 out of the slot 211. At the same time, the rotating rod 28 is wider than the connecting rod 27, which can prevent the connecting rod 27 from falling off and can also make the connecting rod 27 rotate with the rotating rod 28 as the axis. One end of the cross bar 213 away from the limiting rod 212 is fixedly connected to the linkage rod 214. A shaft rod 216 penetrates and is rotatably connected to the inner side of the fixed rail 21. After use, the support leg 25 is pushed and the support leg 25 is contracted to the central position of the mounting seat 1, and then the twisting rod 218 is toggled, so that the twisting rod 218 drives the cam 217 to rotate with the shaft rod 216 as the center. When the cam 217 rotates, it will abut against the arc surface of the linkage rod 214, so that the linkage rod 214 compresses the spring 215 again.

[0027] One end of the insertion rod 29 close to the limiting rod 212 is a bevel surface, and the bottom surface of the limiting rod 212 is an arc surface. The shaft rod 216 penetrates and is fixedly connected to the cam 217, and a twisting rod 218 is fixedly connected to the surface of the cam 217. One end of the linkage rod 214 close to the cam 217 is an arc surface, and a spring 215 is fixedly connected to the end of the linkage rod 214 away from the cam 217. The insertion rod 29 is inserted into the slot 211, and the bevel surface of the insertion rod 29 will gradually abut against the arc surface at the bottom end of the limiting rod 212, so that while the limiting rod 212 is lifted, it will drive the linkage rod 214 to rise together through the cross bar 213. When the linkage rod 214 rises, it will compress the spring 215. One end of the spring 215 away from the linkage rod 214 is fixedly connected to the inner wall of the fixed rail 21.

[0028] Based on the above embodiments, when the surveying device is in use, first, the folding rail 22 is toggled with the rotating rod 28 as the axis, so that the insertion rod 29 fixedly connected to the surface of the folding rail 22 is aligned with the slot 211 and pushed in, so that the insertion rod 29 is inserted into the slot 211. And the inclined surface of the insertion rod 29 will gradually abut against the arc surface at the bottom end of the limiting rod 212, so that while the limiting rod 212 is lifted, the linkage rod 214 will be driven to rise together by the cross bar 213. When the linkage rod 214 rises, the spring 215 will be compressed. When the limiting hole 210 opened on the surface of the insertion rod 29 is aligned with the position of the limiting rod 212, the compressed spring 215 will drive the cross bar 213 through the linkage rod 214 to insert the limiting rod 212 into the limiting hole 210, so that the folding rail 22 is limited and cannot be pulled out. Then, by pulling the support leg 25, the support leg 25 can drive the cross slider 23 to slide in the fixed rail 21 and the folding rail 22 through the hinge block 24, which is more convenient for adjusting the distance and angle between the support legs 25. After use, push the support leg 25 and make the support leg 25 contract to the central position of the mounting seat 1. Then, toggle the twisting rod 218, so that the twisting rod 218 drives the cam 217 to rotate around the shaft rod 216. When the cam 217 rotates, it will abut against the arc surface of the linkage rod 214, so that the linkage rod 214 will compress the spring 215 again, and the linkage rod 214 will drive the limiting rod 212 through the cross bar 213 to no longer insert into the limiting hole 210, and then the folding rail 22 can be pulled out, so that the folding rail 22 can pull the insertion rod 29 out of the slot 211. At the same time, the rotating rod 28 is wider than the connecting rod 27, which can prevent the connecting rod 27 from falling off and can also make the connecting rod 27 rotate around the rotating rod 28 as the axis, so that the folding rail 22 can be folded downwards. By being able to fold the folding rail 22, while expanding the support range of the support leg 25, it is more convenient for storage and carrying.

[0029] With the foldable folding rail 22, the mounting seat 1 does not need to be of a large size, and only needs to be able to fix the surveying instrument 3. The folding and extension of the supporting fixed rail 21 and the folding rail 22 can minimize the distance between the support legs 25 and is more convenient for carrying.

[0030] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements that do not depart from the spirit of the present invention are all within the protection scope of the present invention.
