Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a foldable surveying and mapping device for urban planning surveying and mapping. Background Art

[0002] Surveying and mapping instruments are needed for surveying and mapping operations in urban planning. Surveying and mapping instruments refer to instruments designed and manufactured for surveying and mapping operations such as data collection, processing, and output. There are various types of surveying and mapping instruments, including electronic automatic surveying and mapping and manual surveying and mapping.

[0003] The existing patent authorization number is: CN220251026U, which discloses a foldable surveying instrument for urban planning surveying and mapping, including a surveying instrument body and a foldable triangular support frame fixed under the surveying instrument body, a detection lens is arranged on the surface of the surveying instrument body, a track frame is fixedly connected to the surface of the surveying instrument body, and a sliding block is slidably connected to the inner cavity of the track frame through a sliding groove. When the working environment of the foldable surveying instrument for urban planning surveying and mapping is dusty and adheres to the detection lens, alcohol is dripped into the dripping groove at this time, and the alcohol soaks the alcohol wiping pad through the connecting groove, and then the sliding block is slid on the track frame to drive the connecting plate to move, and the dust on the surface of the detection lens is first wiped off by the dust wiping pad, and then the alcohol wiping pad is used to wipe the dust off. Perform a second detailed wipe to effectively clean the detection lens, which can keep the detection lens clean at all times to prevent affecting the surveying and mapping results; the surveying and mapping instrument mainly controls the flow of alcohol to automatically wipe the lens of the surveying and mapping instrument. Although the electronic surveying and mapping device is easy to operate and accurate in measurement, it is very susceptible to the influence of electricity and external air dust, and often has problems such as insufficient power or internal faults in the surveying and mapping. For the measurement of some local small areas in urban planning, in most cases, it is more practical to use a manual surveying and mapping device with a simpler structure. However, some existing manual surveying and mapping devices have a relatively simple structure and cannot be folded and stored as needed. Moreover, the measurement accuracy is insufficient during measurement;

The slide frame 13 is placed on the slide rail 12 and then cooperated with the surveying and mapping measuring line 11 for mobile precise surveying. A folding moving component is provided between the top of the three groups of mobile slide frames 13 and the top of one end of the slide rail 12 for common rotation. The folding moving component is used to drive the mobile slide frames 13 at different positions to selectively slide along the top of the slide rail 12. While controlling the movement of the mobile slide frame 13 to cooperate with the surveying and mapping pointer 17 to measure the distance, the mobile slide frame 13 can be effectively folded and stored, thereby improving the mutual correlation between the mobile slide frames 13 in the surveying and mapping of the device and improving the efficiency of surveying and mapping.

[0018] In the embodiment of the present invention, the surveying and mapping pointer 17 is set to an isosceles triangle structure, and the distance measurement is performed by using the indication of the surveying and mapping pointer 17 toward the tip of the surveying and mapping measurement line 11 in conjunction with the movement of the moving slide frame 13;

[0019] See also Figure 4 , positioning sliders 15 are installed on the inner side walls of both sides of the mobile slide frame 13, and positioning grooves 16 are opened on the outer side walls of the slide rail 12 corresponding to the positioning sliders 15. The positioning sliders 15 slide along the inside of the positioning grooves 16 to prevent the mobile slide frame 13 from detaching in the vertical direction when it is placed on the slide rail 12 and moves. At the same time, the two ends of the positioning grooves 16 are set to a closed state to prevent the positioning sliders 15 from sliding out of the positioning grooves 16, that is, to prevent the mobile slide frame 13 from sliding off from the slide rail 12.

[0020] In one embodiment of the present invention, the folding moving assembly includes a moving shaft 27 installed at the middle of the top of the moving slide frame 13 and a fixed shaft 14 installed at one end of the top of the slide rail 12. The fixed shaft 14 and the moving shaft 27 farthest from the fixed shaft 14 are respectively rotatably connected with a long outer swing rod I 18 and a long outer swing rod II 19. The long outer swing rod I 18 and the long outer swing rod II 19 are located on the same side of the slide rail 12, and the outer ends are rotatably connected through the swing rod shaft 20. The other two moving shafts 27 at the top of the moving slide frame 13 are rotatably connected to each other. The outer ends of the short outer swing rods Ⅰ21 and Ⅱ22 are respectively connected to the fixed shaft 14 through the swing rod rotating shaft 20. Under the rotation connection of the long outer swing rods Ⅰ18, Ⅱ19 and the swing rod rotating shaft 20, the fixed shaft 14 is connected to the farthest moving shaft 27, that is, when the farthest moving sliding frame 13 is controlled to move, the long outer swing rods Ⅰ18, Ⅱ19 and the swing rod rotating shaft 20 are connected to the fixed shaft 14 through the swing rod rotating shaft 20.

Similarly, under the rotation connection of the swing rod shaft 20, the short outer swing rod I 21, and the short outer swing rod II 22, the relative movement of the two middle moving slide frames 13 is effectively controlled and connected. At the same time, a group of four-bar shafts 28 are arranged above the slide rail 12 between the two middle moving slide frames 13. The four-bar shafts 28 are respectively rotated toward the middle direction of the long outer swing rod I 18, the long outer swing rod II 19, the short outer swing rod I 21, and the short outer swing rod II 22 to connect the long inner swing rod II 24, the long inner swing rod I 23, The short inner swing rod II 26 and the short inner swing rod I 25 are connected to the long inner swing rod I 23, the long inner swing rod II 24, the short inner swing rod I 25 and the short inner swing rod II 26 by swinging, and the long outer swing rod I 18, the long outer swing rod II 19, the short outer swing rod I 21 and the short outer swing rod II 22 are connected to form a whole by swinging. When the three groups of moving slide frames 13 are controlled to move for measurement through the connection between the above structures, the corresponding operation conditions are as follows: the moving slide frames 13 from near to far from the fixed rotating shaft 14 are marked as A, B and C respectively;

[0021] When A is controlled to move, the short outer swing rod II 22 is driven to swing toward the short outer swing rod I 21. At this time, under the connection of the long inner swing rod I 23 and the long inner swing rod II 24, the long outer swing rod II 19 is controlled to expand away from the long outer swing rod I 18, so that C moves backward and B is in a static state, that is, the mobile measurement of A and C is realized;

[0022] When B is controlled to move, the short outer swing rod Ⅰ21 and the short outer swing rod Ⅱ22 are driven to unfold and separate, the long inner swing rod Ⅰ23 and the long inner swing rod Ⅱ24, the long outer swing rod Ⅱ19 and the long outer swing rod Ⅰ18 are synchronously unfolded and separated, thereby driving C to move backward. At this time, A is in a stationary state, that is, the simultaneous mobile measurement of B and C is realized;

[0023] Through the above connection, the device can perform multi-position measurements simultaneously during surveying and mapping, and is simple to operate and has a built-in folding and storage function.

[0024] It should be noted that the long inner swing rod I 23, the long inner swing rod II 24, the short inner swing rod I 25 and the short inner swing rod II 26 are placed on different horizontal planes, that is, they are distributed separately at the rotating assembly of the four-bar shaft 28 to prevent mutual influence and obstruction of normal rotation.

[0025] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
