Abstract
Description
Technical Field
[0001] This utility model relates to a field surveying device for construction engineering cost, belonging to the technical field of surveying devices. Background Technology
[0002] The main function of the on-site cost measurement device for construction projects is to help engineers accurately measure and calculate various data of construction projects, thereby providing a reliable basis for project cost estimation, helping engineers and decision-makers to make more reasonable decisions, optimize design schemes, control costs, and ensure project quality.
[0003] Existing on-site cost surveying devices are typically placed separately from their support legs, and are usually stored in boxes to prevent damage. However, these boxes are mostly made of plastic, and if workers accidentally drop heavy items while searching for items in a warehouse, the boxes containing the devices can easily be damaged. Therefore, we offer a new on-site cost surveying device for construction projects to address these issues. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a construction project cost on-site surveying device, the specific technical solution of which is as follows:
[0005] A construction project cost on-site surveying device includes a base, a fixed block rotatably connected inside the base, a support rod connected to the bottom surface of the fixed block, an extension rod slidably connected inside the support rod, an insert rod slidably connected inside the extension rod, a limit block connected to the bottom surface of the extension rod, a slider rotatably connected inside the limit block, a connecting rod connected to the bottom surface of the slider, a support foot connected to the bottom surface of the connecting rod, a limit hole formed inside the support foot, a fixed plate threaded inside the base, and a plug connected to the outer surface of the fixed plate.
[0006] Preferably, a baffle is slidably connected inside the support rod, and the outer surface of the baffle is slidably connected to the outer surface of the extension rod.
[0007] Preferably, a positioning rod is connected to the upper surface of the baffle, a limiting plate is connected to the upper surface of the positioning rod, the outer surface of the positioning rod is slidably connected to the inside of the support rod, and the outer surface of the limiting plate is slidably connected to the inside of the support rod.
[0008] Preferably, a surveying instrument is mounted on the upper surface of the base, and the outer surface of the insertion rod is slidably connected to the inside of the support rod.
[0009] Preferably, a limiting plate is slidably connected inside the limiting block, and a transmission block is connected to the outer surface of the limiting plate.
[0010] Preferably, the outer surface of the limiting plate is slidably connected to the interior of the slider, and the outer surface of the transmission block is slidably connected to the interior of the limiting block.
[0011] Preferably, a resistance block is connected to the outer surface of the fixing block, and the outer surface of the resistance block is rotatably connected to the interior of the base.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This on-site construction cost surveying device utilizes the cooperation of components such as an extension rod, a slider, and a limiting plate. Firstly, the extension rod can rotate, forming a 90-degree angle with the support rod. The slider can also rotate, forming a 90-degree angle with the connecting rod, making the connecting rod parallel to the support rod. This allows the support legs to contact each other above the surveying instrument, forming a cage-like shape that covers the instrument. This protects the surveying instrument from damage when a heavy object falls on it. The limiting plate restricts the position of the support legs, connecting them to prevent them from falling apart. It is very practical and solves the problem of surveying instruments being easily damaged by impacts.
[0014] 2. This on-site construction cost surveying device utilizes the cooperation between components such as baffles and limiting plates. The baffles can move to block the extension rod, preventing it from rotating arbitrarily when pulled out of the support rod. The limiting plates can move within the limiting block and the slider. Under the action of gravity, the limiting plates can insert into the slider from the limiting block, thus preventing the slider from rotating. This provides sufficient position for the surveying instrument to perform surveying and ensures that the support rod, extension rod, and connecting rod are aligned in a straight line, preventing arbitrarily bending, which is very convenient.

[0022] The present invention will now be further described with reference to the accompanying drawings.
[0023] Please see Figure 1 - Figure 6 The system includes a base 1, with a fixed block 2 rotatably connected inside the base 1. A support rod 3 is connected to the bottom surface of the fixed block 2. A rod is installed inside the base 1, and the fixed block 2 is installed on the outer surface of the rod. The fixed block 2 can rotate along the outer surface of the rod, and the base 1 also restricts the position of the fixed block 2, preventing the fixed block 2 from moving laterally along the rod. The rotation angle of the fixed block 2 is restricted by the base 1. When the fixed block 2 rotates to a position parallel to the upper and lower surfaces of the base 1, it will be restricted by the base 1 and cannot continue to rotate. The fixed block 2 will fix the position of the support rod 3. When the fixed block 2 rotates, it will rotate the support rod 3 along with it, so as to make the support rod 3 parallel to the upper and lower surfaces of the base 1.
[0024] An extension rod 4 is slidably connected inside the support rod 3, and an insertion rod 5 is slidably connected inside the extension rod 4. The outer surface of the insertion rod 5 is slidably connected to the inside of the support rod 3. The support rod 3 restricts the direction in which the extension rod 4 can move, thereby preventing the extension rod 4 from deviating from its position. The extension rod 4 fixes the position of the insertion rod 5. When the extension rod 4 moves, it will move the insertion rod 5 with it. The support rod 3 restricts the position in which the insertion rod 5 can move, and by restricting the position in which the insertion rod 5 can move, the position in which the extension rod 4 can move is restricted. When the insertion rod 5 moves to the bottom, the space opened inside the support rod 3 is sufficient for the extension rod 4 to rotate. Moreover, when the extension rod 4 is at a 90-degree angle to the support rod 3, its side will be blocked by the inner wall of the space opened in the support rod 3.
[0025] The bottom surface of the extension rod 4 is connected to the limiting block 6. The slider 7 is rotatably connected inside the limiting block 6. The extension rod 4 will restrict the position of the limiting block 6. When the extension rod 4 moves, it will move the limiting block 6 with it. The limiting block 6 has a rod inside. When the slider 7 can rotate to ninety degrees along the outer surface of the rod, the outer surface of the slider 7 will be blocked by the limiting block 6.
[0026] The bottom surface of slider 7 is connected to connecting rod 8, and the bottom surface of connecting rod 8 is connected to support foot 9. Slider 7 will fix the position of connecting rod 8. When slider 7 moves, it will move connecting rod 8 with it, so that connecting rod 8 can be at a 90-degree angle with limit block 6. Connecting rod 8 will fix the position of support foot 9. When connecting rod 8 moves, it will move support foot 9 with it.
[0027] The support foot 9 has a limiting hole 10 inside. The base 1 is internally threaded with a fixing plate 11. The outer surface of the fixing plate 11 is connected with a plug 12. The surface of the fixing plate 11 is connected with a threaded rod. The user can connect the fixing plate 11 to the base 1 through the threaded rod. The plug 12 of the fixing plate 11 can be inserted into the limiting hole 10. When the support rod 3 is parallel to the upper and lower surfaces of the base 1, the extension rod 4 is at a 90-degree angle to the support rod 3, and the connecting rod 8 is at a 90-degree angle to the limiting block 6, the three plugs 12 will be directly above the base 1. At this time, the user can remove the fixing plate 11 and insert the plugs 12 into the limiting hole 10 to connect the three plugs 12.
[0028] The support rod 3 has a baffle 13 slidably connected inside. The outer surface of the baffle 13 is slidably connected to the outer surface of the extension rod 4. The support rod 3 restricts the direction in which the baffle 13 can move. The baffle 13 blocks the extension rod 4 so that the extension rod 4 cannot rotate. The baffle 13 can descend on its own under the action of gravity.
[0029] A positioning rod 14 is connected to the upper surface of the baffle 13, and a limiting plate 15 is connected to the upper surface of the positioning rod 14. When the baffle 13 moves, it will move the positioning rod 14, and when the positioning rod 14 moves, it will move the limiting plate 15.
[0030] The outer surface of the positioning rod 14 is slidably connected to the inside of the support rod 3, and the outer surface of the limiting plate 15 is slidably connected to the inside of the support rod 3. The support rod 3 restricts the direction of movement of the positioning rod 14, and the limiting plate 15 can only move within the support rod 3, thereby limiting the position that the positioning rod 14 can move.
[0031] A surveying instrument 16 is mounted on the upper surface of the base 1. A limiting plate 17 is slidably connected inside the limiting block 6. A transmission block 18 is connected to the outer surface of the limiting plate 17. The surveying instrument 16 can be mounted above the base 1 as in existing equipment. The limiting plate 17 cannot be completely detached from the limiting block 6. When the transmission block 18 moves, it will move the limiting plate 17 along with it.
[0032] The outer surface of the limiting plate 17 is slidably connected to the inside of the slider 7, and the outer surface of the transmission block 18 is slidably connected to the inside of the limiting block 6. The slider 7 restricts the position that the limiting plate 17 can move. By inserting the transmission block 18 into the limiting block 6, the position of the limiting block 6 is restricted, so that the limiting block 6 cannot rotate.
[0033] The outer surface of the fixed block 2 is connected to the resistance block 19. The outer surface of the resistance block 19 is rotatably connected to the inside of the base 1. The fixed block 2 will fix the position of the resistance block 19. When the fixed block 2 moves, it will move the resistance block 19 with it. The surface of the resistance block 19 is relatively rough, so as to increase the friction between the fixed block 2 and the base 1, so that the fixed block 2 will not move too flexibly.
[0034] The surveying instrument 16 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.
[0035] When using this utility model, firstly, the fixing plate 11 needs to be rotated down, then the fixing block 2 is rotated so that the fixing block 2 is parallel to the upper and lower surfaces of the base 1. Then, the baffle 13 is moved so that the baffle 13 moves into the support rod 3. Then, the extension rod 4 is rotated to a position perpendicular to the support rod 3. Then, the transmission block 18 is moved so that the limiting plate 17 is pulled out from the slider 7. Then, the slider 7 is rotated to a position perpendicular to the limiting block 6. In this way, the plug 12 will be directly above the base 1. At this time, the user can pick up the fixing plate 11 and insert the plug 12 into the limiting hole 10.
[0036] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
