[0002] As a key measuring tool in construction, the surveying benchmark in building engineering is used throughout the entire project lifecycle, playing an important role from early planning to final acceptance. Its applications are numerous. For example, during the construction of the main structure, in the construction of walls and columns, the benchmark serves as a reference for verticality detection, and is used in conjunction with a total station or laser plumb line for calibration.

[0003] Construction engineering surveying benchmarks are important tools used in construction engineering surveying to determine height, elevation, verticality, or as a measurement reference. They are usually composed of a pole, fixing devices, and auxiliary accessories. Their core function is to provide a stable vertical reference line or a fixed height benchmark for surveying instruments, ensuring the accuracy of measurement data and construction precision.

[0004] In existing technologies, most use single or multi-section metal rods, such as aluminum alloy or carbon fiber, which are connected by threads or buckles. The height is adjustable and the stability is high, but they are inconvenient to carry and take up a lot of space. Therefore, in order to address the above problems, a building engineering surveying rod with a folding structure is proposed. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail. This application discloses a surveying benchmark for building engineering with a folding structure. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A construction engineering surveying pole with a folding structure includes a support plate 1. A base 11 is mounted on the top of the outer wall of the support plate 1. A plurality of first fixing frames 12 are fixedly connected to the bottom of the outer wall of the base 11. A connecting block 13 is rotatably connected to the outer wall of the first fixing frame 12. A first support leg 14 is fixedly connected to the bottom of the outer wall of the connecting block 13. A connecting sleeve 15 is fixedly connected to the inner wall of the first support leg 14. The inner wall of the connecting sleeve 15 slides in contact with a limiting plate 16. The bottom of the outer wall of the limiting plate 16... A connecting rod 17 is fixedly connected to the first support leg 14. A second fixing frame 18 is fixedly connected to the bottom of the outer wall of the connecting rod 17. A connecting strip 19 is rotatably connected to the outer wall of the second fixing frame 18. A third fixing frame 10 is rotatably connected to the inner wall of the connecting strip 19. A second support leg 101 is fixedly connected to the bottom of the outer wall of the third fixing frame 10. A threaded sleeve 102 is fixedly connected to the outer wall of the second support leg 101. The threaded sleeve 102 is threadedly connected to the first support leg 14. A groove 103 is opened on the side wall of the threaded sleeve 102.

[0020] When the equipment is working, rotating the second support leg 101 causes the threaded sleeve 102 to rotate until the threaded sleeve 102 disengages from the first support leg 14. Pulling the second support leg 101 outward causes the connecting bar 19 to pull the connecting rod 17 to move. Continue pulling the second support leg 101 until the connecting bar 19 extends beyond the first support leg 14. At this time, the limiting plate 16 slides to the bottom of the connecting sleeve 15, bending the second support leg 101 so that it folds along the direction of the connecting bar 19. The third fixing frame 10 rotates around the connecting bar 19 until the slot 103 overlaps with the connecting bar 19. During the bending process, the second fixing frame 18 and the connecting bar 19 also rotate in coordination until the second support leg 101 and the first support leg 14 are folded together. By using the connecting bar 19 and the threaded sleeve 102, the first support leg 14 and the second support leg 101 can be folded together, reducing the space occupied by the equipment and making it easier for staff to store and carry the equipment.

[0021] Reference Figure 1 and Figure 5 The bottom of the inner side wall of the second support leg 101 is threaded with a first threaded post 2. The bottom of the outer side wall of the first threaded post 2 is fixed with a pair of fixing plates 21. The side wall of the fixing plate 21 is fixed with a connecting post 22. The outer side wall of the connecting post 22 is rotatably connected with a support post 23. The bottom of the outer side wall of the support post 23 is fixed with a base plate 24. The outer side wall of the first threaded post 2 is fixed with a first connecting plate 25. The first connecting plate 25 is in contact with the second support leg 101.

[0022] When the equipment is working, rotating the first connecting plate 25 can rotate the first threaded column 2. At this time, the distance between the first connecting plate 25 and the second support leg 101 will change. When the base plate 24 contacts the ground, the support column 23 and the connecting column 22 will rotate to increase the contact area between the base plate 24 and the ground. With the first connecting plate 25 and the first threaded column 2, it is convenient for the staff to adjust the equipment according to the ground conditions, so that the height of a single support leg of the equipment can be changed, reducing the situation where the equipment cannot be used normally due to low ground flatness.

[0023] Reference Figure 1 and Figure 6 The bottom of the outer side wall of the support plate 1 is fixedly connected to several limiting cylinders 3. The inner side wall of the limiting cylinder 3 is threadedly connected to a second threaded post 31. The bottom of the outer side wall of the second threaded post 31 is fixedly connected to a tapered leg 32. The outer side wall of the second threaded post 31 is fixedly connected to a second connecting disc 33.

[0024] When the equipment is working and encounters soft soil, the second connecting plate 33 can be rotated to rotate the second threaded post 31 until the second threaded post 31 disengages from the limiting cylinder 3. Then, the first connecting plate 25 can be rotated until the first threaded post 2 disengages from the second support leg 101. At this time, the limiting cylinder 3 can be screwed into the bottom of the second support leg 101. At this time, the tapered leg 32 can replace the base plate 24 to support the equipment. The tapered leg 32 and the second threaded post 31 make it easy for the staff to adjust the equipment according to the actual situation and adapt the equipment to different terrains.

[0025] Reference Figure 3 and Figure 4 A pair of limiting blocks 4 are fixed to the outer wall of the second support leg 101, and a collar 41 is slidably contacted on the outer wall of the first support leg 14, and the collar 41 is in contact with the second support leg 101.

[0026] When the equipment is working, the collar 41 can be slid above the limiting block 4. At this time, the collar 41 will be placed in the middle position between the first support leg 14 and the second support leg 101. The collar 41 will restrict the first support leg 14 and the second support leg 101 to a certain extent. The stability of the connection between the first support leg 14 and the second support leg 101 is increased by setting the limiting block 4 and the collar 41 when the equipment is working.

[0027] Reference Figure 5 The outer side wall of the first connecting plate 25 has several scraping grooves 5.

[0028] When the equipment is working, the scraper groove 5 can scrape away the sweat and other liquids that stick to the worker's palm when the worker rotates the first connecting plate 25. The scraper groove 5 reduces the probability of slippage when the worker rotates the first connecting plate 25, making it easier for the worker to use the equipment.

[0029] Reference Figure 3 and Figure 4 The outer side wall of the first support leg 14 is provided with a threaded line 6, which is threadedly connected to the collar 41.

[0030] When the equipment is working, the operator can screw the collar 41 onto the thread 6. At this time, the thread 6 can fix the collar 41. The thread 6 makes it easy for the operator to place the collar 41.

[0031] Reference Figure 4 The connecting strip 19 is made of a rigid material.

[0032] When the equipment is working, the connecting strip 19 plays an important connecting role. By making the connecting strip 19 a rigid material, the possibility of the connecting strip 19 bending and breaking during equipment operation is reduced.

[0033] Working principle: When the equipment is working, rotating the second support leg 101 causes the threaded sleeve 102 to rotate until the threaded sleeve 102 disengages from the first support leg 14. Pulling the second support leg 101 outward causes the connecting bar 19 to pull the connecting rod 17 to move. Continue pulling the second support leg 101 until the connecting bar 19 extends beyond the first support leg 14. At this time, the limiting plate 16 slides to the bottom of the connecting sleeve 15, bending the second support leg 101 so that it folds along the direction of the connecting bar 19. The third fixing bracket 10 rotates around the connecting bar 19 until the slot 103 overlaps with the connecting bar 19. During the bending process, the second fixing bracket 18 and the connecting bar 19 also rotate in coordination until the second support leg 101... The first support leg 14 and the second support leg 101 can be folded together via the connecting strip 19 and the threaded sleeve 102, reducing the space occupied by the equipment and making it easier for staff to store and carry. When the equipment is in operation, rotating the first connecting plate 25 causes the first threaded column 2 to rotate, changing the distance between the first connecting plate 25 and the second support leg 101. When the base plate 24 contacts the ground, the support column 23 and the connecting column 22 rotate to increase the contact area between the base plate 24 and the ground. The first connecting plate 25 and the first threaded column 2 allow staff to adjust the equipment according to ground conditions, allowing each support leg to be folded. The height can be adjusted to reduce the possibility of equipment malfunction due to uneven ground. When the equipment encounters soft soil during operation, the second connecting plate 33 can be rotated to rotate the second threaded post 31 until it disengages from the limiting cylinder 3. Then, the first connecting plate 25 can be rotated until the first threaded post 2 disengages from the second support leg 101. At this point, the limiting cylinder 3 can be screwed into the bottom of the second support leg 101. The tapered leg 32 can then replace the base plate 24 to support the equipment. The tapered leg 32 and the second threaded post 31 allow operators to easily adjust the equipment according to actual conditions, making it adaptable to different terrains. When the equipment is in operation, the collar 41 can be slid above the limiting block 4. At this point, the collar 41 will... Positioned between the first support leg 14 and the second support leg 101, the collar 41 provides a certain constraint on the connection between them. The limiting block 4 and the collar 41 increase the stability of the connection between the first support leg 14 and the second support leg 101 during operation. When the equipment is working, the scraper groove 5 can remove sweat and other liquids adhering to the operator's palms when rotating the first connecting plate 25. The scraper groove 5 reduces the probability of slippage when rotating the first connecting plate 25, facilitating operation. During operation, the operator can screw the collar 41 onto the threaded wire 6, which then secures the collar 41.To facilitate the placement of the collar 41 by the staff, the connecting strip 19 plays an important connecting role during equipment operation. By making the connecting strip 19 a rigid material, the possibility of bending and breakage during equipment operation is reduced.
