Detailed Implementation

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5A portable geographic information surveying and mapping device according to a utility model embodiment includes: a housing 6, with a detector 3 slidably connected inside the housing 6 for geographic information surveying and mapping; a lens 13 fixedly connected to the front surface of the detector 3; the lens 13 is located at the center of the front surface of the detector 3; cooling fans are fixedly connected to the left and right sides of the detector 3 for heat dissipation; a main connecting shaft 12 is rotatably connected to the left and right sides of the housing 6 for connecting the handle and various moving parts inside the housing, with a handle 8 and a transmission gear 18 fixedly connected to the main connecting shaft 12, transmitting the rotation of the handle to the rotation of the gear through the connecting shaft; a limit block 2 is fixedly connected to the side surface of the housing 6 to limit the range of motion of the handle 8; a rack 4 is fixedly connected in the grooves on the upper and lower side surfaces of the detector 3, the rack 4 meshing with the transmission gear 18, which can convert the rotation of the transmission gear 18 into horizontal movement;

[0024] A ratchet and pawl mechanism 17 is provided on the inner right side surface of the housing 6; the ratchet and pawl mechanism 17 includes a ratchet and a pawl, the ratchet is fixedly connected to the main connecting shaft 12, the pawl is engaged with the ratchet, and the pawl is fixedly connected to the fixed shaft on the right side of the housing 6. The unidirectional rotation of the transmission gear can be realized through the above ratchet and pawl mechanism.

[0025] A sealing door 1 is rotatably connected to the front end of the enclosure 6 to protect the equipment inside the enclosure 6; a top block 20 is rotatably connected to the front end of the enclosure 6 to open the sealing door 1; a cam transmission mechanism is provided on the lower inner surface of the enclosure 6, the cam transmission mechanism including a starting cam 19 and a guide rail 21, the lower surface of the starting cam 19 being rotatably connected to the lower inner wall of the enclosure 6, the upper surface of the starting cam 19 being rotatably connected to both the detector 3 and the guide rail 21, the guide rail 21 being rotatably connected to the transmission shafts on both sides of the enclosure 6, and the transmission shafts being rotatably connected to the rotation shaft of the top block 20. Through the above mechanism, the sliding of the detector 3 can be associated with the rotation of the top block 20; a main cooling fan 7 is fixedly connected to the rear surface of the enclosure 6 for heat dissipation of the equipment inside the enclosure;

[0026] When transitioning from storage to operation, rotating handle 8 causes the main connecting shaft to rotate, which in turn drives the ratchet and transmission gear 18 to rotate. The rotation of transmission gear 8 causes the detector 3 to slide outward along the track via rack 4, which is fixedly connected to the detector 3. The sliding of detector 3 causes starting cam 19 to rotate around its fixed shaft, which is fixed to the lower inner wall of housing 6. The rotation of starting cam 19 drives the transmission shaft, which is connected to the rotation shaft of top block 20, to slide along the guide groove on housing 6 via guide rail 21. One end of the transmission shaft is connected to the outer surface of top block 20. The sliding of the transmission shaft can pull top block 20 to rotate around its rotation shaft, thus allowing the detector 3 to slide outward, and the sealing door 1 to open automatically. During this process, the ratchet and pawl ensure that detector 3 is only allowed to move outward, preventing unnecessary shaking. When storage is needed, rotate the handle on the right side surface of the housing 6 to release the pawl, and then rotate the handle 8 in the opposite direction. The rotation of the handle 8 drives the transmission gear 18 to rotate in the opposite direction, which drives the detector 3 to slide inward through the rack 4. At the same time, through the starting cam 19 and the guide rail 21, the detector 3 drives the aforementioned transmission shaft to slide in the opposite direction. After the detector 3 enters the housing, as the detector 3 moves inward, the top block 20 gradually reduces the force applied to the sealing door 1. Under the action of the spring, the sealing door 1 gradually closes until it reaches the storage position.

[0027] A connecting seat 15 is fixedly connected to the center of the lower surface of the housing 6. Connecting grooves are provided around the connecting seat 15 and are evenly distributed around the central axis of the connecting seat 15 for connecting the bracket 9. The bracket 9 is used to provide stable support for the entire device in the working state. A connecting block groove is provided on the rectangular side of the bracket 9, and a connecting block 14 is rotatably connected in the connecting block groove. The connecting block 14 is hinged to the connecting groove on the connecting seat 15 to realize the rotation of the bracket 9. Guide grooves 11 are provided on the four side surfaces and the lower side surface of the housing 6 to restrict the movement of the bracket 9 in the storage state.

[0028] A display screen 5 is rotatably connected to the upper surface of the housing 6 to display relevant data during operation.

[0029] A power supply 16 is fixedly connected to the lower inner wall of the housing 6. The power supply 16 is separated from the detector 3 by a partition and is used to store electrical energy. A charging port 10 is provided on the side surface of the housing 6 for connecting a charging cable.

[0030] Working Principle: When surveying is not required, all functional modules are located inside the housing 6, protected by the sealing door 1. When surveying is required, turning the handle 8 to the rear of the housing 6 causes the detector 3 to move towards the opening of the housing 6 via the transmission gear 18 and rack 4. Simultaneously, the detector 3 drives the top block 20 to rotate via the starting cam 19 and guide rail 21, opening the sealing door 1 to both sides. The detector 3 then extends from the housing 6 to perform measurement and surveying. While the detector 3 is in operation, the ratchet and pawl mechanism 17 prevents it from sliding inward, thus preventing data errors caused by inward or outward movement. If necessary, the support 9 can be unfolded and lowered from the four sides of the housing 6, and its movement is restricted by the connecting seat 15 to ensure stable support for the equipment. When the work is completed and the equipment needs to be put away, the handle located on the right outer surface of the housing 6, which is fixedly connected to the fixed shaft and fixedly connected to the ratchet, is rotated to release the restriction on the rotation of the ratchet. Then, the handle 8 is rotated in the opposite direction to realize the retraction movement of the detector base 3. At the same time as the detector 3 moves, the sealing door 1 is automatically closed by the spring, so that the entire equipment returns to a portable state.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
