Description

Technical Field

[0001] The invention relates to the technical field of land surveying and mapping equipment, and in particular to a land surveying and mapping equipment that can be quickly folded and stored. Background Art

[0002] Land surveying and mapping refers to the use of computer technology, optoelectronic technology, network communication technology, space science, and information science as the basis, with the Global Positioning System (GPS), remote sensing (RS), and geographic information system (GIS) as the technical core, to obtain graphics and location information reflecting the current status of the ground through measurement methods based on the existing characteristic points and boundaries on the ground for the planning, design, and administrative management of engineering construction.

[0003] When conducting land surveying, a level is generally used. However, in sandy areas, the wind contains a lot of sand, which causes sand to enter the tripod bracket below the level after the level is stored. When carrying the level, sand leaks out from the tripod bracket, which can easily cause damage to the level. Improvements need to be made to this problem.

[0004] Therefore, it is necessary to design a land surveying and mapping device that is highly practical and can be quickly folded and stored to prevent the level from being damaged by sand. Summary of the invention

[0005] The object of the present invention is to provide a land surveying and mapping device that can be quickly folded and stored to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a land surveying and mapping device that can be quickly folded and stored, comprising a level, a storage mechanism, a folding mechanism and a protective mechanism, wherein the bottom of the level is fixedly connected to a chassis.

[0007] Wherein, the storage mechanism comprises:

[0008] A rotating block is rotatably connected to the middle of the front side of the chassis, a bracket is fixedly connected to the side of the rotating block away from the chassis, a fixed shaft is fixedly connected to the middle of the bottom of the chassis, a positioning ring is fixedly connected to the bottom outside the fixed shaft, a deformation plate is rotatably connected to the outside of the positioning ring, a rotating frame 2 is rotatably connected to the side of the deformation plate away from the positioning ring, and a sliding sleeve is fixedly connected to the side of the rotating frame 2 away from the deformation plate.

[0009] According to the above technical solution, the folding mechanism includes a folding groove, a fixing bolt, a fixing nut, a rotating leg, an outer guard plate, an insert plate and a supporting foot. The folding groove is opened on the front of the bracket, the fixing bolt is fixedly connected to the bottom of the right side of the folding groove, the right end of the fixing nut is threadedly connected to the middle of the fixing bolt, the rotating leg is rotatably connected to the middle of the fixing nut, the outer guard plate is fixedly connected to the back of the rotating leg, the insert plate is fixedly connected to the bottom of the rotating leg, and the supporting foot is fixedly connected to the bottom of the insert plate.

[0010] According to the above technical scheme, the protective mechanism includes a magnetic block 1, a fixed plate, a spring, a cleaning frame, a cleaning roller, a magnetic block 2, an air bag and a blowing pipe, the magnetic block 1 is fixedly connected to the front of the plug plate, the fixed plate is fixedly connected to the bottom of the back side of the folding groove, the spring is fixedly connected to the top of the fixed plate, the cleaning frame is fixedly connected to the top of the spring, the cleaning roller is rotatably connected to the inner side of the cleaning frame, the magnetic block 2 is fixedly connected to the top of the cleaning frame, the air bag is fixedly connected to the top of the folding groove, and the blowing pipe is fixedly connected to the left and right sides of the bottom of the air bag.

[0011] According to the above technical solution, a rotating frame 1 is fixedly connected to the outer side of the positioning ring, the deformable plate is rotatably connected to the inner middle part of the rotating frame 1, the positioning ring is rotatably connected to the deformable plate through the rotating frame 1, and a pair of deformable plates can be provided to support the rotating frame.

[0012] According to the above technical solution, the inner side of the sliding sleeve is slidably connected to the outer side of the bracket, so that the sliding sleeve can slide on the bracket.

[0013] According to the above technical solution, the right end of the fixing nut passes through the left side of the bracket, the left side of the rotating leg, the right side of the rotating leg and the right side of the bracket and extends to the middle of the fixing bolt and is threadedly connected to the fixing bolt, so as to support and fix the rotating leg.

[0014] According to the above technical solution, sliding grooves are opened on the left and right sides of the folding groove, and sliders are set on the left and right sides of the cleaning frame corresponding to the sliding grooves. The cleaning frame is slidably connected to the inner wall of the bracket through the sliders, so that the cleaning frame can slide on the inner wall of the bracket.

[0015] According to the above technical solution, a pressure valve is provided at the top of the blowing pipe. By providing the pressure valve, leakage of air in the air bag caused by accidental touching can be avoided.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, when the level needs to be stored, the rotating leg is rotated to move the magnetic block 1 at the bottom of the rotating leg to the front of the bracket, and the magnetic block 1 is inserted into the folding groove, so that the magnetic block 1 is close to and contacts the magnetic block 2. At this time, the magnetic block 1 and the magnetic block 2 are magnetically adsorbed, so that the magnetic block 2 drives the cleaning frame to rise, and at the same time, the cleaning roller inside the cleaning frame contacts and rolls on the side of the rotating leg stored in the bracket. When the cleaning roller contacts the rotating leg, the cleaning roller rolls and cleans the outer wall of the rotating leg, and the swept sand leaks out through the bottom of the folding groove, so as to avoid the sand being stored together into the inside of the triangular bracket when it is stored and folded, causing damage to the level during subsequent storage.

[0017] When the magnetic block is inserted into the folding groove, the magnetic block contacts and squeezes the air bag. At this time, the air in the air bag is blown downward through the pressure valve in the blowing pipe, and dust can be blown from the side of the rotating leg close to the inner wall of the bracket, so as to avoid sand on the cleaning roller, and ensure that there will be no sand inside the device after storage, which will cause safety hazards when the level is stored;

[0018] When folding and storage is required, it is only necessary to rotate the rotating leg to insert the magnetic block into the folding groove, and at the same time push it from the outside of the bracket to the fixed axis. At this time, the deformable plate in the rotating frame one on the positioning ring rotates, causing the sliding sleeve to slide upward on the outside of the bracket, and at the same time, the side of the bracket close to the fixed axis is brought closer to the fixed axis, thereby reducing the overall space volume of the device, so that the device occupies less space after being folded and stored, making the device easy to store and carry.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-4 The present invention provides a technical solution: a land surveying and mapping device that can be quickly folded and stored, including a level 1, a storage mechanism 3, a folding mechanism 4 and a protective mechanism 5, and a chassis 2 is fixedly connected to the bottom of the level 1.

[0032] Wherein, the storage mechanism 3 comprises:

[0033] A rotating block 301 is rotatably connected to the middle of the front of the chassis 2. A bracket 302 is fixedly connected to the rotating block 301 away from the chassis 2.

At this time, the deformable plate 305 in the rotating frame 1 on the positioning ring 304 rotates, causing the sliding sleeve 307 to slide upward on the outside of the bracket 302, and at the same time, the side of the bracket 302 close to the fixed axis 303 is brought closer to the fixed axis 303, thereby reducing the overall space volume of the device, so that the device occupies less space after being folded and stored, making the device easy to store and carry.

[0039] The right end of the fixing nut 403 passes through the left side of the bracket 302, the left side of the rotating leg 404, the right side of the rotating leg 404 and the right side of the bracket 302 and extends to the middle of the fixing bolt 402 and is threadedly connected to the fixing bolt 402, which can support and fix the rotating leg 404.

[0040] Slide grooves are provided on the left and right sides of the folding groove 401, and sliders are provided on the left and right sides of the cleaning frame 504 corresponding to the slide grooves.

[0041] A pressure valve is provided at the top of the blowing pipe 508 to prevent air leakage in the air bag 507 caused by accidental touching.

[0042] When the level needs to be stored, the rotating leg 404 is rotated to move the magnet 501 at the bottom of the rotating leg 404 to the front of the bracket 302, and the magnet 501 is inserted into the folding groove 401, so that the magnet 501 is close to and contacts the magnet 2 506.
