Technical Field

[0001] This utility model relates to the field of engineering surveying technology, specifically to a benchmark for engineering surveying. Background Technology

[0002] Currently, surveying refers to measuring and sampling the shape, size, spatial location, and attributes of natural geographical elements or artificial structures on the earth's surface and drawing them into maps. Although there are many types of surveying poles on the market today, most of them are just changes in form, and their functions have not changed much. In the current use of surveying poles, there is only a single head and pole, which is unstable during surveying, causing inconvenience to the staff and affecting the surveying results, resulting in reduced surveying efficiency. At the same time, the traditional surveying poles are too tall and inconvenient to carry. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 5 This utility model provides a technical solution: a marker for engineering surveying, including a first connecting rod 1 and a second connecting rod 3. The first connecting rod 1 has a plurality of recycling grooves 5 on its inner outer side. A rotating plate 7 is rotatably connected inside the plurality of recycling grooves 5. A support plate 8 is slidably connected inside the rotating plate 7. Sliding grooves 15 are provided on both sides of the inner cavity of the rotating plate 7. A locking block 13 is slidably connected inside the two sliding grooves 15. A second spring 14 is fixedly connected to one side of the locking block 13. The second spring 14 is fixedly connected to the support plate 8. Two locking holes 12 are provided on both sides of the rotating plate 7. The two locking holes 12 cooperate with the two locking blocks 13.

[0020] A mating block 20 is fixedly installed on the top of the first connecting rod 1. An annular groove 21 is formed on the outer side of the mating block 20. A ball groove 16 is formed on the bottom of the second connecting rod 3. Several movable balls 18 are arranged inside the ball groove 16. The several movable balls 18 are in rolling connection with the second connecting rod 3. A connecting groove 17 is formed inside the second connecting rod 3. Parts of the several movable balls 18 are located on the outer side of the second connecting rod 3 and inside the connecting groove 17. By changing the partial structural position of each movable ball 18, it is determined whether it mates with the annular groove 21. The connecting groove 17 mates with the mating block 20, and the several movable balls 18 mate with the annular groove 21. Through the mate of the several movable balls 18 with the annular groove 21 and the mate of the connecting groove 17 with the mating block 20, the device is easy to assemble and disassemble.

[0021] The outer side of the second connecting rod 3 is threaded with an outer limiting sleeve 2. The outer limiting sleeve 2 cooperates with several movable balls 18. A pull plate 4 is fixedly installed on the outer side of the outer limiting sleeve 2. The outer limiting sleeve 2 can control the left and right movement of several movable balls 18. The pull plate 4 facilitates the movement of the outer limiting sleeve 2. An annular baffle is provided on the outer side of the first connecting rod 1 to prevent the outer limiting sleeve 2 from moving downward too far.

[0022] The first connecting rod 1 has several pins 9 slidably connected inside. One end of each pin 9 extends into the inside of the recycling trough 5. A fixing block 10 is fixedly connected to the outside of each pin 9. The fixing block 10 is located inside the recycling trough 5. A first spring 11 is fixedly connected to one side of the fixing block 10. The first spring 11 is fixedly connected to the first connecting rod 1. A hole 19 is provided on one side of the support plate 8. The hole 19 cooperates with the pins 9. Through the cooperation of the hole 19 and the pins 9, the support plate 8 and the rotating plate 7 are fixed after recycling.

[0023] Several limiting blocks 6 are fixedly installed on the outer side of the first connecting rod 1, and the angle of the rotating plate 7 is limited by the limiting blocks 6.

[0024] In summary, for the surveying pole used in this project, the first connecting rod 1 and the second connecting rod 3 are held by hand during use. When assembling the device, firstly, the tip of the first connecting rod 1 is brought into contact with the ground. Then, the pull plate 4 is pushed upwards by hand, causing the outer limiting sleeve 2 to move upwards. After the outer limiting sleeve 2 moves upwards, several movable balls 18 will move outwards. At this time, the mating block 20 is inserted into the connecting groove 17. Then, the outer limiting sleeve 2 is pushed downwards. Through the compression of the outer limiting sleeve 2, several movable balls 18 move inwards. The engagement of these movable balls 18 with the annular groove 21 facilitates the assembly of the device. When stabilizing the surveying pole, firstly... First, pull several pins 9, using the pulling force to cause the first spring 11 to elastically deform, thereby pulling the pins 9 out of the socket 19. Then, rotate several rotating plates 7 outwards, and adjust the support plate 8 according to different situations. Hold the two locking blocks 13 by hand, so that the support plate 8 can extend and retract, thereby contacting the ground and achieving stability of the device during measurement. When not in use, the operator can retract the support plate 8 into the rotating plate 7, and then pull the pins 9. When the rotating plate 7 rotates into the recycling trough 5, release the pins 9. Under the elastic force of the first spring 11, the pins 9 are inserted into the socket 19, thereby achieving the purpose of fixing the recycled support plate 8.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
